+The Southeast African cheetah (Acinonyx jubatus jubatus) is the nominate cheetah subspecies native to East and Southern Africa. The Southern African cheetah lives mainly in the lowland areas and deserts of the Kalahari, the savannahs of Okavango Delta, and the grasslands of the Transvaal region in South Africa. In Namibia, cheetahs are mostly found in farmlands.
+
+
+== Taxonomy ==
+
+The Southern African cheetah was first described by German naturalist Johann Christian Daniel von Schreber in his book Die Säugethiere in Abbildungen nach der Natur mit Beschreibungen (The Mammals illustrated as in Nature with Descriptions), published in 1775. Schreber described the species on basis of a specimen from the Cape of Good Hope. It is therefore the nominate subspecies. Subpopulations have been called "South African cheetah" and "Namibian cheetah."Following Schreber's description, other naturalists and zoologists also described cheetah specimens from many parts of Southern and East Africa that today are all considered synonyms of A. j. jubatus:
+Felis guttata proposed in 1804 by Johann Hermann;
+Felis fearonii proposed in 1834 by Andrew Smith;
+Felis lanea proposed in 1877 by Philip Sclater;
+Acinonyx jubatus obergi proposed in 1913 by Max Hilzheimer;
+Acinonyx jubatus ngorongorensis proposed in 1913 by Hilzheimer on basis of a specimen from Ngorongoro, German East Africa;
+Acinonyx jubatus velox proposed in 1913 by Edmund Heller on basis of a cheetah that was shot by Kermit Roosevelt in June 1909 in the Kenyan highlands.
+Acinonyx rex proposed in 1927 by Reginald Innes Pocock on basis of a specimen from the Umvukwe Range in Rhodesia.In 2005, the authors of Mammal Species of the World grouped A. j. guttata, A. j. lanea, A. j. obergi, and A. j. rex under A j. jubatus, whilst recognizing A. j. raineyi and A. j. velox as valid taxa and considering P. l. ngorongorensis as synonymous with raineyi.In 2017, the Cat Classification Task Force of the Cat Specialist Group subsumed all cheetah populations from most parts of Eastern and Southern Africa to A. j. jubatus, thus making it the most widespread subspecies in the continent.
+
+
+== Evolutionary history ==
+From the early Pleistocene, the earliest African cheetah fossils have been found in the lower beds of the Olduvai Gorge site in northern Tanzania, although cheetah fossils in Southern Africa were found to be 3.5 to 3.0 million years old. The Southeast African cheetah is the second-oldest subspecies.Cheetahs from Africa and Asia were previously considered as genetically identical with each other. DNA research and analysis started in the early 1990s and showed that the Southern and East African cheetahs are indeed separate subspecies.Until September 2009, the Asiatic cheetah was thought to be identical to African cheetahs. Stephen J. O'Brien from the Laboratory of Genomic Diversity of the National Cancer Institute was of the opinion that they have been separated from each other for only 5,000 years, which is not enough time to be classified as distinct subspecies.In early 2011, results of phylogeographic analysis of 94 cheetah samples from museum collections, wild and captive specimens, revealed that Southeast African and Asiatic cheetahs are genetically distinct, and probably diverged between 32,000 and 67,000 years ago. The mitochondrial DNA data indicate that the cheetah samples from East Africa had no common haplotype with samples from Southern Africa, although one haplotype present in cheetah samples from Tanzania and Kenya clustered with samples from South Africa. The population in East Africa might have derived from a relatively recent recolonization event. The divergence between the cheetah populations in Southern, East and Northern Africa occurred between 6,700 and 32,400 years ago.
+
+
+== Genetics ==
+
+Historically, cheetahs were thought to be genetically homogeneous. In 2011, results of a phylogeographic study revealed that the Asiatic cheetah and cheetah populations in Africa are genetically distinct and separated between 32,000 and 67,000 years ago.The woolly cheetah was discovered in the late 19th century by English zoologist Philip Sclater. It was considered as a separate species of cheetah that had a thicker body, and longer and denser fur. Several specimens were obtained. These creatures may be the same species as the present-day cheetah, but with a genetic disposition to long fur. In 1877, Sclater, of the Zoological Society of London, wrote of a recent acquisition by the zoo. In 1878, a second woolly cheetah was reported as a preserved specimen in the South African Museum. Both the London and South African specimens had come from Beaufort West. In 1884, a third skin was obtained from the same area, though this had more distinct spots and was a little smaller. By the late 1880s, the trophy hunters had eliminated the woolly cheetahs; from the number and locality of specimens, this variant seems to have evolved very recently (generations rather than millennia); perhaps all those animals (it seems only a handful are known at best) were the offspring of a single couple born around 1875, or maybe one more generation. The woolly cheetah has, in any case, vanished.The king cheetah was considered a different species in 1927 by naturalist Reginald Innes Pocock. It was found to be a mutation caused by a recessive gene. The king cheetah is a rare variant of the Southern cheetah, first discovered in southern Rhodesia in 1925. A king cheetah was first found in South Africa in 1940 and in Botswana in 1942. However, in 1981, king cheetahs were shown to have never been a different species, as king cheetahs were born from regular parents at the De Wildt Cheetah and Wildlife Centre in South Africa, and another king cheetah were born from two female cheetahs having mated with a wild-caught male cheetah from the Transvaal Province, and more king cheetahs were born later at the De Wildt Cheetah Centre. The king cheetahs are found in South Africa, Zimbabwe, and Botswana. In 2012, the cause of this alternative coat pattern was found to be a mutation in the gene for transmembrane aminopeptidase Q (Taqpep), the same gene responsible for the striped "mackerel" versus blotched "classic" patterning seen in tabby cats.The cheetah also has melanism as one of its rare color morphs. A melanistic cheetah in Zambia was seen by Vesey Fitzgerald in the company of a spotted cheetah.
+
+
+== Physical characteristics ==
+
+The cheetah is a medium-sized cat. An adult male cheetah's total size can measure from 168 to 200 cm (66 to 79 in) and 162 to 213 cm (64 to 84 in) for females. Adult cheetahs are 70 to 90 cm (28 to 35 in) tall at the shoulder. Males are slightly taller than females and have slightly bigger heads with wider incisors and longer mandibles.Measurements taken of wild cheetahs in Namibia indicate that the females range in head-and-body length from 113 to 140 cm (44 to 55 in) with 59.5-to-73.0 cm (23.4-to-28.7 in) long tails, and weigh between 21.0 and 63.0 kg (46.3 and 138.9 lb); males range in head-and-body length from 113 to 136 cm (44 to 54 in) with 60-to-84 cm (24-to-33 in) long tails, and weigh between 28.5 and 65.0 kg (62.8 and 143.3 lb).The cheetah has a bright yellow or sometimes a golden coat, and its fur is slightly thicker than that of other subspecies. The white underside is very distinct, especially on the neck and breast, and it has less spotting on its belly. The spots on the face are more pronounced, and as a whole its spots seem more dense than those of most other subspecies. The tear marks are notably thicker at the corners of the mouth, and almost all of them have distinct brown mustache markings. Like the Asiatic cheetah, it is known to have fur behind its tail and have both white and black tips at the end of its tail. However, the cheetah may also have only a black tip at the end of its tail.
+In desert areas, such as the Kalahari, cheetahs are somewhat smaller and lighter in weight, with thinner, bright-colored fur, a trait the Northwest African cheetah also has.
+
+
+== Distribution and habitat ==
+
+The Southeast African cheetah usually lives on grasslands, savannahs, scrub forests, and arid environments such as  deserts and semidesert steppes. These cheetahs can be found in open fields, where they chase and hunt herbivorous mammals such as antelopes at a very high speed. In South Africa, the cheetah also prefers woodlands (in Kruger National Park), shrublands, high mountains, mountainous grasslands, and montane areas where favorable prey are mostly available.
+The Southeast African cheetah is currently the most common subspecies and was widespread everywhere in southern to central Africa, ranging from South Africa to the southern Democratic Republic of the Congo (Katanga Province) and southern Tanzania. Its range is now greatly reduced, where it occurs in an area of 1,223,388 km2 (472,353 sq mi), 22% of its original range.In the past, less than 10,000 cheetahs were hunted in Namibian farmlands. Previously estimated at mere 2,000 individuals since the 1990s, as of 2015, over 3,500 cheetahs live in Namibia today. The country maintains the largest population of wild cheetahs worldwide. About 90-95% of the cheetahs live on Namibian farmlands; others live in the Kalahari Basin, the coastal deserts of Namib and Kaokoveld, and the central to northeastern region of the country. Although Namibian cheetahs are mostly found outside of protected areas, they also live in Naankuse Wildlife Sanctuary, Namib-Naukluft National Park, and Bwabwata National Park. The cheetahs are rather uncommon in Etosha National Park and in Palmwag.
+With an approximate population of 2,000 cheetahs as of 2016, Botswana has the second-largest population of cheetahs. They are mostly found in arid habitats of the Central Kalahari, Mokolodi Nature Reserve, and Kgalagadi Transfrontier Park (known as Gemsbok National Park in Botswana) in the south, and in the southwest and also in the northern region of the country that holds the largest prey base, such as in Okavango Delta, Chobe National Park, and Moremi Game Reserve. Khutse Game Reserve is also known to contain high abundance of suitable prey base for cheetahs, such as springboks, gemsboks, and wildebeests. Cheetahs are rarely found in the eastern Botswana and at the Zimbabwean border.
+In South Africa, cheetahs live in the Limpopo, Mpumalanga, North West, and Northern Cape Provinces. After conservation efforts throughout the years, cheetahs have been reintroduced in the eastern, western, and southern parts, and recently in the Free State province of the country. Over 90% of the cheetah population is found outside protected areas such as game reserves and in farmlands. More than 412 cheetahs are in Kruger National Park, subpopulations of 300 to 350 in parks and reserves, and 400 to 500 free-roaming on farmlands in the Limpopo and North West Province, although the Kgalagadi Transfrontier Park is the stronghold for cheetahs.  Kruger and Kalahari Gemsbok National Parks hold the largest populations; they are home to roughly 42% of South Africa's cheetahs. Cheetahs had not always been common in South Africa. As of now, the country contains the third-largest population of cheetahs after years of conservation actions and reintroductions into the wild. In 2016, it is estimated about 1,500 adult cheetahs live in the wild.
+The population of cheetahs has been dramatically decreased in Zimbabwe, from about a thousand to 400, as of 2007. Currently, the Zimbabwean population is estimated at 165 individuals. Prior the population decline, cheetahs were more widespread in Zimbabwe, and its population had excellent growth rate, in which over 1,500 individuals thrived. Back in 1973, an estimated 400 cheetahs lived in Zimbabwe and had increased to 470 in 1987. Afterwards in 1991, a total population of 1,391 cheetahs was found by the Zimbabwe Department of Parks and Wildlife Management, whilst in 1996, a population of 728 cheetahs lived on commercial farmlands alone. In 1999, a minimum total population of 1,520 was estimated, in which over 1,200 of these cheetahs lived on commercial farmlands, while 320 were found in national parks. A year later, several reports questioned whether the Zimbabwean cheetahs were stable or decreasing, but it was increasing at the time. However, cheetahs are known to be highly threatened in farmlands in which between 1999 and 2007, 80% of the population of Zimbabwean cheetahs living in private farmlands fell into massive decline due to human-cheetah conflict, reduced from over a thousand to less than 400 as of 2007. About 100 cheetahs were killed by livestock farmers in Zimbabwe's lowveld per year. Following years later, about 150 to 170 adult cheetahs are found there, and the human-cheetah conflict is no longer a major threat to the species. Most of the Zimbabwean cheetahs live in protected areas today. Cheetahs are mainly found in the southern to central regions. Isolated populations are found in northwestern Zimbabwe, such as Victoria Falls, Matetsi, and Kazuma Pan, also near the Mozambican border. Hwange National Park, the largest reserve with an area of 14,650 km2 (5,660 sq mi), is the main stronghold for the Zimbabwean cheetahs. Cheetahs also live in Matobo National Park. The cheetahs of the Zambezi Valley are nearly extinct, as only three individuals remain in Matusadona National Park and 9 in the Mana Pools National Park. Twenty-nine remain in the Zimbabwean lowveld, most of which live in Gonarezhou National Park, private reserves (Bubye, Save, Malilangwe, Nuanetsi), and at the Chilojo Cliffs.In Zambia, cheetahs are mostly spotted at Matamene Camp of Liuwa Plain National Park from the Western Province. The national park is part of the Kavango–Zambezi Transfrontier Conservation Area. They are also present at the 5,000 km2 (1,900 sq mi) Kafue National Park, near the Kafue River and at the 22,400 km2 (8,600 sq mi) Sioma Ngwezi National Park (the second-largest park in Africa) in the southwest corner of Zambia. About 100 cheetahs live in the country.
+In 2007, between 50 and 90 cheetahs were estimated to survive in Mozambique, where the species inhabits grasslands, savannahs, and mixed Acacia and mopane woodlands. Most habitats consist of wetlands and rivers. Historically, it was widespread in the country, but by 1975, the population had declined to about 200 individuals due to intense poaching during the Mozambican Civil War. Camera traps set up in 2004 and 2011 revealed constant presence of cheetahs, other predators and herbivores in Mozambique's conservation areas in Great Limpopo Transfrontier Park. Around 35 cheetahs live in Limpopo National Park. Cheetahs are also present in Zinave National Park and Banhine National Park, which are part of the Great Limpopo Transfrontier Park.Apart from the central and northern regions, the now-rare cheetah lived in southern Tanzania. It ranged close to the Zambia/Malawi borders in the southwest to the southeasternmost part of the country. These cheetahs are found at Mpanga-Kipengere Game Reserve and the Uwanda Game Reserve. Whether or not they are extinct in Selous Game Reserve is unknown.
+The indigenous population of cheetahs was extinct in Eswatini. In 1997, three cheetahs have been reintroduced into the Hlane Royal National Park, the largest (30,000 ha (300 km2)) protected area of Eswatini.The cheetah was once thought to be extinct in Angola, but in 2010 two adult male cheetahs were spotted in the 16,000 km2 (6,200 sq mi) Iona National Park. It was the first time cheetahs have been sighted in the wild of Angola in 30 years. This protected area provides suitable habitat for the cheetah, as it has a large, open savannah where springbok and oryx occur.In the 1980s, cheetahs occurred in three protected areas, namely Kasungu National Park, Nyika National Park and Vwaza Marsh Game Reserve, also at the Zambian border in the west. In 2007, the small cheetah population was considered locally extinct due to loss of suitable habitat and lack of prey.
+
+
+=== Former range ===
+In early 20th century, African cheetahs were widespread everywhere in the continent, until they lost most of their ranges and disappeared from 23 countries. Cheetahs are locally extinct from Lesotho and the southern part of the Democratic Republic of the Congo. They used to live in the Katanga, southern Bandundu, southern Kasai-Occidental, and Bas-Congo. They probably extended to Kinshasa. It was previously estimated that about 100 to 500 cheetahs lived in the Congo between 1950-70s. Kundelungu National Park was one of the remaining stronghold for the cheetahs after recent extinction of cheetahs from Virunga National Park and Sudan cheetahs from Garamba National Park during the 1960s. Rumored sightings have been reported occasionally in the southern regions of the Congo, such as near the Angolan border, around the Sandoa Territory and on the Kibara Plateau of Upemba National Park. To this day, Upemba is still considered as the only national park of the country to contain cheetah populations.
+
+
+== Ecology and behavior ==
+
+
+=== Reproduction and lifecycle ===
+Male cheetahs are sociable and may live in a group with other males. Males establish their territories by marking their territories by urinating on trees or termite mounds.
+The females, though, are not sociable and do not establish a territory. They are solitary and avoid each other. However, they may live with their mothers, daughters, or sisters on their home ranges. The female's home range's size can depend on the prey base. Cheetahs in southern African woodlands have ranges as small as 34 km2 (13 sq mi), while in some parts of Namibia, they can reach 1,500 km2 (580 sq mi).
+Female cheetahs can reproduce at 13 to 16 months of age and with a typical age of sexual maturity between 20 and 23 months. The gestation can last for 90 to 95 days. Cub births mostly occur at November to January in Namibia and November to March in Zambia. Females hunt solo, except the cheetah cubs accompany their mothers to learn how to hunt on their own after the age of 5–6 weeks. After the cubs reach 18 months of age, the mother leaves her cubs, and the siblings remain as a group for a few months until the sisters leave the group and the brothers stay together. The male cubs may form alliances with other males after separating from their mother.
+
+
+=== Hunting and diet ===
+
+The cheetah is a carnivorous mammal. It preys on medium-sized and large antelopes, and fast, small animals such as Cape hares and rodents. It prefers Thomson's gazelles, impala, kudu, puku, oribi, springbok, gemsbok, steenbok, wildebeest, warthog, red hartebeest, and other ungulates. The cheetah's preferred prey species is the oryx and the nyala
+
+
+=== Enemies and competitors ===
+Like other cheetahs, they are threatened and outranked by larger predators in their area. They are threatened by lions and spotted hyenas as they can steal their carcasses. The cheetahs would surrender their meals to spotted hyenas. However, coalitions of male adult cheetahs can chase predators away, and a single cheetah can chase jackals and a lone wild dog away.
+
+
+== Threats ==
+The Southern cheetah is a vulnerable subspecies, due to poaching, habitat loss, and lack of prey. Indiscriminate capture and removal of wild cheetahs in southern Africa continue to threaten the survival of this species, as it may reduce the genetic diversity in the wild and they breed poorly in captivity. Its survival is also threatened by inbreeding. In Botswana, the cheetahs are mostly threatened by habitat changes.
+The cheetah was also highly threatened by hunting and range loss. In early 1930s, the cheetahs were hunted down and almost went extinct in South Africa. Therefore, it has lost most of its range, mostly in South Africa and Mozambique. Only a few dozen of them live in the southern part of Mozambique. It also disappeared from many regions of South Africa, only living in the northern and northeastern parts of the country.
+During the 1970s, 9,500 cheetahs were killed in Namibian farmlands. As a protected species in Namibia, people are allowed to remove Namibian cheetahs only if they pose a threat to livestock or human life. Unfortunately, farmers might capture Namibian cheetahs, often removing or killing those that have not taken any livestock. About 90% of the Namibian cheetah population live on farmlands.
+In Botswana, the cheetah is protected under the Conserved Animal legislation since 1968, which strictly limits hunting and capture. Before then, the decline of suitable prey caused the cheetahs to feed on livestock. About 50 cheetah were previously hunted down by tribesmen each year to protect livestock.
+Limited international trade in live animals and skins is permitted from Namibia, Zimbabwe, and Botswana.
+
+
+== Conservation status ==
+
+Previously estimated at a population of 4,190 individuals in Southern Africa since 2007, the total population of the Southern cheetah has likely reached over 6,000 individuals, with Namibia having the largest cheetah population worldwide. Since 1990, the population was estimated to be about 2,500 individuals in Namibia; until 2015, the cheetah population has  increased to more than 3,500 in the country. Botswana contains the second-largest population of cheetahs - in 2007, an estimated population of 1,800. However, in 2016, about 2,000 cheetahs were in Botswana, which is about 20% of the world's cheetahs. Around 550 to 850 cheetahs were left in South Africa in 2007. After many conservation efforts, the cheetah population has boosted to more than 1,000. In 2013, the estimated population was between 1,200 and 1,300 cheetahs in South Africa. Whilst an estimated that 1,500 adult cheetahs live in South Africa since 2016, the Endangered Wildlife Trust stated that the total population ranges between 1,166 and 1,742 cheetahs in South Africa alone in 2017. In Zimbabwe, on the contrary, the cheetahs' population has severely declined, from more than 1,500 cheetahs since 1999 to 400 cheetahs in 2007, to between 150 and 170 cheetahs as of 2015. In 2007, around 100 individuals remained in Zambia and between 50 and 90 were left in Mozambique.Several conservation projects for the cheetah species exist in African countries and Iran. Like the Asiatic cheetah, the Southern cheetah got more attention from people than other subspecies.
+Three cheetah subspecies are included on the IUCN list of vulnerable species (three African subspecies threatened, Northwest African and Asiatic subspecies in critical condition), as well as on the US Endangered Species Act: threatened species - Appendix I of CITES (Convention on International Trade in Endangered Species).
+Founded in Namibia in 1990, the Cheetah Conservation Fund's mission is to be the world's resource charged with protecting the cheetah and to ensure its future. The organization works with all stakeholders within the cheetah's ecosystem to develop best practices in research, education, and ecology, and create a sustainable model from which all other species, including people, will benefit. Around 12,400 cheetahs were estimated to remain in the wild in 25 African countries. Recently, 6,674 mature individuals were found by the IUCN; Namibia has the most, with more than 3,500, of which 90% of them are living outside of protected areas. Breeding programs have been successful, including the use of in vitro fertilization, in zoos around the world.
+The cheetahs are known to be poor breeders in captivity, though several organizations, such as the De Wildt Cheetah and Wildlife Centre, have succeeded in breeding high numbers of cheetah cubs. In 2009, the centre has bred more than 800 cubs.
+
+
+== Reintroduction projects ==
+
+
+=== In Africa ===
+
+
+==== South Africa ====
+The cheetah once occurred in several areas of Southern Africa, but not commonly in South Africa.
+The species lives mostly on the eastern and northern locations of South Africa. Since the 1960s, the cheetah had been imported from Namibia, which used to contain healthy populations of cheetahs at the time, and has been reintroduced to their former ranges and in small reserves. About 29% of the cheetah population was indigenously from South Africa whilst 71% was those imported from Namibia. The first known reintroductions were in KwaZulu Natal, Gauteng, Lowveld, Eastern Cape, Western Cape, and Southern Kalahari. There are currently 1,500 mature cheetahs within the country.In December 2003, after the cheetahs were heavily hunted in the Great Karoo and Eastern Cape areas to extinction 125 years ago, cheetahs have returned to the Karoo, starting with a severely injured female wild-born cheetah named Sibella (circa 2001 – 11 September 2015) that went through surgery at the De Wildt Cheetah and Wildlife Trust and was later reintroduced to Samara Private Game Reserve. The reintroduction process was a success. Sibella was a capable hunter and successfully raised 18 cubs. About 2% of the wild population of cheetahs in South Africa occurs in that region. The cheetahs living in Samara are also in better condition,  threats from apex predators such as lions and hyenas no longer exist. Sibella's youngest daughter Chilli has given birth to the first third-generation cheetah cubs of the Samara Private Game Reserve in January 2017.A National Cheetah Metapopulation Project was launched in 2011 by the Endangered Wildlife Trust. Its purpose is to develop and co-ordinate a national metapopulation management plan for cheetahs in smaller fenced reserves in South Africa. For instance, the cheetahs have been reintroduced in around 50 of these South African reserves. Fragmented subpopulations of cheetahs are currently increasing in a few hundreds. As of July 2014, further plans exist to reintroduce the cheetahs in six more small fenced reserves over the next few years.
+For the first time after 100 years of extinction since the colonial period, the cheetah has recently been reintroduced into the Free State in 2013, with two male wild cheetahs that have been relocated from the Eastern Cape's Amakhala Game Reserve to the Free State's Laohu Valley Reserve, where the critically endangered South China tiger from Save China's Tigers (SCT) are part of a rewilding project in South Africa. A female cheetah has yet to be reintroduced to Laohu Valley. In early 2016, an adult female has been reintroduced to the reserve. Three wild cheetah cubs have been born for the first time in Laohu Valley Reserve in February 2017, making them the first cheetahs born in the wild since their disappearance from the Free State province in over a century. With three mature individuals and three cubs, six cheetahs are in Laohu Valley Reserve.In 2016, a reintroduction and rewilding project known as Rewilding iSimangaliso for cheetahs is going on in iSimangaliso situated in KwaZulu-Natal province, including lions and Cape wild dogs, which were first introduced in late 2013. The 15 collared resident cheetahs in uMkhuze Game Reserve are seen by visitors during game drives.

+In May 2017, two male and two female cheetahs were imported from South Africa and reintroduced to Liwonde National Park.
+
+
+==== Zambia ====
+Since 1989, only a few cheetahs had been recorded at the Lower Zambezi National Park, despite the area being apparently suitable habitat for cheetahs. Chiawa Camp, in association with National Parks and Wildlife and Japan Aid, approached the Cheetah Conservation Fund for a study group to assess the suitability of Lower Zambezi. In October 1994, reintroduction attempts were made with three cheetahs to the Lower Zambezi. However, the reintroduction project had been unsuccessful, as two of them were killed by traps; one survivor remained for three years alone. Further plans exist to reintroduce the cheetah to the Lower Zambezi.

+=== Outside Africa ===
+
+Asiatic cheetahs had existed in India for thousands of years, but as a result of hunting and other disastrous causes, they have disappeared there, with the last known Indian cheetah having been spotted in 1951. The critically endangered species currently lives in Iran, as the country itself is unwilling to give their cheetahs to India. A captive propagation project has been proposed. Minister of Environment and Forests Jairam Ramesh told the Rajya Sabha on 7 July 2009, "The cheetah is the only animal that has been described extinct in India in the last 100 years. We have to get them from abroad to repopulate the species." He was responding to a call for attention from Rajiv Pratap Rudy of the Bharatiya Janata Party (BJP). "The plan to bring back the cheetah, which fell to indiscriminate hunting and complex factors like a fragile breeding pattern is audacious given the problems besetting tiger conservation." Two naturalists, Divya Bhanusinh and MK Ranjit Singh, suggested importing cheetahs from Namibia, after which they will be bred in captivity and, in time, released in the wild.Multiple suitable potential sites from the Indian states of Gujarat, Madhya Pradesh, and Rajasthan which consisted of forests, grasslands, savannahs, and deserts were chosen for the cheetah reintroduction project in India, such as Banni Grasslands Reserve, Desert National Park, Palpur-Kuno Wildlife Sanctuary and Gajner Wildlife Sanctuary. They are also known to be where the Asiatic cheetahs and other mystical animals coexisted for several years until they had recently gone extinct from the region. Nauradehi Wildlife Sanctuary was chosen as the most suitable site for reintroduced Namibian cheetahs.However, the plan to introduce this subspecies to India has been suspended in 2012, after discovering the distinctness between the cheetahs from Asia and Africa, having been separated between 32,000 and 67,000 years ago.
+
+
+== In captivity ==
+
+Cheetahs are known to be difficult to breed in captivity because of their social behaviors and breeding problems. The cub mortality in captivity and in the wild is high at about 50%. On average, 30% of all captive-bred cubs born in captivity may die within a month.The Southern cheetah is the most widespread subspecies breeding in captivity around the world, while  Sudanese cheetahs are found only in a few European and Middle Eastern zoos and wildlife centers. The subspecies is found in various zoos worldwide in America, Africa, Eurasia, and Australia.
+Several zoos, facilities, breeding centers, and wildlife parks part of the American (Species Survival Plan, Association of Zoos and Aquariums) and Eurasian (European Endangered Species Programme, European Association of Zoos and Aquaria) captive-breeding programs have been successfully increasing populations of cheetahs, such as White Oak Conservation from Yulee, Florida, the Wildlife Safari from Winston, Oregon, that bred more than 178 cheetahs and the De Wildt Cheetah and Wildlife Centre from South Africa where hundreds of cheetah cubs have been born. The Fota Wildlife Park from Ireland is also known for successfully breeding cheetahs in captivity right before starting a captive-breeding project with the Northeast African cheetah.

The films Cheetah (1989) and Duma (2005) were both loosely based on this book. However, Duma takes place in South Africa instead of Kenya. The cheetahs that starred in the film were South African cheetahs from the Kragga Kamma Game Park of the Eastern Cape province. In November 2011, one of the five adult cheetahs that starred in the film had died from an unusual kidney failure.

+The cheetah (Acinonyx jubatus) is a large cat native to Africa and central Iran. It is the fastest land animal, estimated to be capable of running at 80 to 128 km/h (50 to 80 mph) with the fastest reliably recorded speeds being 93 and 98 km/h (58 and 61 mph), and as such has evolved specialized adaptations for speed, including a light build, long thin legs and a long tail. It typically reaches 67–94 cm (26–37 in) at the shoulder, and the head-and-body length is between 1.1 and 1.5 m (3 ft 7 in and 4 ft 11 in). Adults weigh between 21 and 72 kg (46 and 159 lb). Its head is small and rounded, with a short snout and black tear-like facial streaks. The coat is typically tawny to creamy white or pale buff and is mostly covered with evenly spaced, solid black spots. Four subspecies are recognised.
+The cheetah lives in three main social groups: females and their cubs, male "coalitions", and solitary males. While females lead a nomadic life searching for prey in large home ranges, males are more sedentary and instead establish much smaller territories in areas with plentiful prey and access to females. The cheetah is active  during the day, with peaks during dawn and dusk. It feeds on small- to medium-sized prey, mostly weighing under 40 kg (88 lb), and prefers medium-sized ungulates such as impala, springbok and Thomson's gazelles. The cheetah typically stalks its prey to within 60–70 m (200–230 ft), charges towards it, trips it during the chase and bites its throat to suffocate it to death. It breeds throughout the year. After a gestation of nearly three months, a litter of typically three or four cubs is born. Cheetah cubs are highly vulnerable to predation by other large carnivores such as hyenas and lions. They are weaned at around four months and are independent by around 20 months of age.
+The cheetah occurs in a variety of habitats such as savannahs in the Serengeti, arid mountain ranges in the Sahara and hilly desert terrain in Iran. The cheetah is threatened by several factors such as habitat loss, conflict with humans, poaching and high susceptibility to diseases. Historically ranging throughout most of Sub-Saharan Africa and extending eastward into the Middle East and to central India, the cheetah is now distributed mainly in small, fragmented populations in central Iran and southern, eastern and northwestern Africa. In 2016, the global cheetah population was estimated at 7,100 individuals in the wild; it is listed as Vulnerable on the IUCN Red List. In September 2022, they were reintroduced to India after being extinct in the country for 70 years. In the past, cheetahs were tamed and trained for hunting ungulates. They have been widely depicted in art, literature, advertising, and animation.
+
+
+== Etymology ==
+The vernacular name "cheetah" is derived from Hindustani Urdu: چیتا and Hindi: चीता (ćītā). This in turn comes from Sanskrit: चित्रय (Chitra-ya) meaning 'variegated', 'adorned' or 'painted'. In the past, the cheetah was often called "hunting leopard" because they could be tamed and used for coursing. The generic name Acinonyx probably derives from the combination of two Greek words: ἁκινητος (akinitos) meaning 'unmoved' or 'motionless', and ὄνυξ (onyx) meaning 'nail' or 'hoof'. A rough translation is "immobile nails", a reference to the cheetah's limited ability to retract its claws. A similar meaning can be obtained by the combination of the Greek prefix a– (implying a lack of) and κῑνέω (kīnéō) meaning 'to move' or 'to set in motion'. The specific name jubatus is Latin for 'crested, having a mane'.A few old generic names such as Cynailurus and Cynofelis allude to the similarities between the cheetah and canids.
+
+
+== Taxonomy ==
+
+In 1777, Johann Christian Daniel von Schreber described the cheetah based on a skin from the Cape of Good Hope and gave it the scientific name Felis jubatus. Joshua Brookes proposed the generic name Acinonyx in 1828. In 1917, Reginald Innes Pocock placed the cheetah in a subfamily of its own, Acinonychinae, given its striking morphological resemblance to the greyhound and significant deviation from typical felid features; the cheetah was classified in Felinae in later taxonomic revisions.In the 19th and 20th centuries, several cheetah specimens were described; some were proposed as subspecies. An example is the South African specimen known as the "woolly cheetah", named for its notably dense fur—this was described as a new species (Felis lanea) by Philip Sclater in 1877, but the classification was mostly disputed. There has been considerable confusion in the nomenclature of cheetahs and leopards (Panthera pardus) as authors often confused the two; some considered "hunting leopards" an independent species, or equal to the leopard.
+
+
+=== Subspecies ===
+In 1975, five subspecies were considered valid taxa: A. j. hecki, A. j. jubatus, A. j. raineyi, A. j. soemmeringii and A. j. venaticus. In 2011, a phylogeographic study found minimal genetic variation between A. j. jubatus and A. j. raineyi; only four subspecies were identified. In 2017, the Cat Classification Task Force of the IUCN Cat Specialist Group revised felid taxonomy and recognised these four subspecies as valid. Their details are tabulated below:
+
+
+== Phylogeny and evolution ==
+The cheetah's closest relatives are the cougar (Puma concolor) and the jaguarundi (Herpailurus yagouaroundi). Together, these three species form the Puma lineage, one of the eight lineages of the extant felids; the Puma lineage diverged from the rest 6.7 mya. The sister group of the Puma lineage is a clade of smaller Old World cats that includes the genera Felis, Otocolobus and Prionailurus.The oldest cheetah fossils, excavated in eastern and southern Africa, date to 3.5–3 mya; the earliest known specimen from South Africa is from the lowermost deposits of the Silberberg Grotto (Sterkfontein). Though incomplete, these fossils indicate forms larger but less cursorial than the modern cheetah. Fossil remains from Europe are limited to a few Middle Pleistocene specimens from Hundsheim (Austria) and Mosbach Sands (Germany). Cheetah-like cats are known from as late as 10,000 years ago from the Old World. The giant cheetah (A. pardinensis), significantly larger and slower compared to the modern cheetah, occurred in Eurasia and eastern and southern Africa in the Villafranchian period roughly 3.8–1.9 mya. In the Middle Pleistocene a smaller cheetah, A. intermedius, ranged from Europe to China. The modern cheetah appeared in Africa around 1.9 mya; its fossil record is restricted to Africa.Extinct North American cheetah-like cats had historically been classified in Felis, Puma or Acinonyx; two such species, F. studeri and F. trumani, were considered to be closer to the puma than the cheetah, despite their close similarities to the latter. Noting this, palaeontologist Daniel Adams proposed Miracinonyx, a new subgenus under Acinonyx, in 1979 for the North American cheetah-like cats; this was later elevated to genus rank. Adams pointed out that North American and Old World cheetah-like cats may have had a common ancestor, and Acinonyx might have originated in North America instead of Eurasia. However, subsequent research has shown that Miracinonyx is phylogenetically closer to the cougar than the cheetah; the similarities to cheetahs have been attributed to convergent evolution.The three species of the Puma lineage may have had a common ancestor during the Miocene (roughly 8.25 mya). Some suggest that North American cheetahs possibly migrated to Asia via the Bering Strait, then dispersed southward to Africa through Eurasia at least 100,000 years ago; some authors have expressed doubt over the occurrence of cheetah-like cats in North America, and instead suppose the modern cheetah to have evolved from Asian populations that eventually spread to Africa. The cheetah is thought to have experienced two population bottlenecks that greatly decreased the genetic variability in populations; one occurred about 100,000 years ago that has been correlated to migration from North America to Asia, and the second 10,000–12,000 years ago in Africa, possibly as part of the Late Pleistocene extinction event.
+
+
+== Genetics ==
+The diploid number of chromosomes in the cheetah is 38, the same as in most other felids. The cheetah was the first felid observed to have unusually low genetic variability among individuals, which has led to poor breeding in captivity, increased spermatozoal defects, high juvenile mortality and increased susceptibility to diseases and infections. A prominent instance was the deadly feline coronavirus outbreak in a cheetah breeding facility of Oregon in 1983 which had a mortality rate of 60%—higher than that recorded for previous epizootics of feline infectious peritonitis in any felid. The remarkable homogeneity in cheetah genes has been demonstrated by experiments involving the major histocompatibility complex (MHC); unless the MHC genes are highly homogeneous in a population, skin grafts exchanged between a pair of unrelated individuals would be rejected. Skin grafts exchanged between unrelated cheetahs are accepted well and heal, as if their genetic makeup were the same.The low genetic diversity is thought to have been created by two population bottlenecks from c. 100,000 years and c. 12,000 years ago, respectively. The resultant level of genetic variation is around 0.1–4% of average living species, lower than that of Tasmanian devils, Virunga gorillas, Amur tigers, and even highly inbred domestic cats and dogs.
+
+
+=== King cheetah ===
+
+The king cheetah is a variety of cheetah with a rare mutation for cream-coloured fur marked with large, blotchy spots and three dark, wide stripes extending from the neck to the tail. In Manicaland, Zimbabwe, it was known as nsuifisi and thought to be a cross between a leopard and a hyena. In 1926 Major A. Cooper wrote about a cheetah-like animal he had shot near modern-day Harare, with fur as thick as that of a snow leopard and spots that merged to form stripes. He suggested it could be a cross between a leopard and a cheetah. As more such individuals were observed it was seen that they had non-retractable claws like the cheetah.In 1927, Pocock described these individuals as a new species by the name of Acinonyx rex ("king cheetah"). However, in the absence of proof to support his claim, he withdrew his proposal in 1939. Abel Chapman considered it a colour morph of the normally spotted cheetah. Since 1927 the king cheetah has been reported five more times in the wild in Zimbabwe, Botswana and northern Transvaal; one was photographed in 1975.In 1981, two female cheetahs that had mated with a wild male from Transvaal at the De Wildt Cheetah and Wildlife Centre (South Africa) gave birth to one king cheetah each; subsequently, more king cheetahs were born at the centre. In 2012, the cause of this coat pattern was found to be a mutation in the gene for transmembrane aminopeptidase  (Taqpep), the same gene responsible for the striped "mackerel" versus blotchy "classic" pattern seen in tabby cats. The appearance is caused by reinforcement of a recessive allele; hence if two mating cheetahs are heterozygous carriers of the mutated allele, a quarter of their offspring can be expected to be king cheetahs.
+
+
+== Characteristics ==
+
+The cheetah is a lightly built, spotted cat characterised by a small rounded head, a short snout, black tear-like facial streaks, a deep chest, long thin legs and a long tail. Its slender, canine-like form is highly adapted for speed, and contrasts sharply with the robust build of the genus Panthera. Cheetahs typically reach 67–94 cm (26–37 in) at the shoulder and the head-and-body length is between 1.1 and 1.5 m (3 ft 7 in and 4 ft 11 in). The weight can vary with age, health, location, sex and subspecies; adults typically range between 21 and 72 kg (46 and 159 lb). Cubs born in the wild weigh 150–300 g (5.3–10.6 oz) at birth, while those born in captivity tend to be larger and weigh around 500 g (18 oz). Cheetahs are sexually dimorphic, with males larger and heavier than females, but not to the extent seen in other large cats. Studies differ significantly on morphological variations among the subspecies.The coat is typically tawny to creamy white or pale buff (darker in the mid-back portion). The chin, throat and underparts of the legs and the belly are white and devoid of markings. The rest of the body is covered with around 2,000 evenly spaced, oval or round solid black spots, each measuring roughly 3–5 cm (1.2–2.0 in). Each cheetah has a distinct pattern of spots which can be used to identify unique individuals. Besides the clearly visible spots, there are other faint, irregular black marks on the coat. Newly born cubs are covered in fur with an unclear pattern of spots that gives them a dark appearance—pale white above and nearly black on the underside. The hair is mostly short and often coarse, but the chest and the belly are covered in soft fur; the fur of king cheetahs has been reported to be silky. There is a short, rough mane, covering at least 8 cm (3.1 in) along the neck and the shoulders; this feature is more prominent in males. The mane starts out as a cape of long, loose blue to grey hair in juveniles. Melanistic cheetahs are rare and have been seen in Zambia and Zimbabwe. In 1877–1878, Sclater described two partially albino specimens from South Africa.The head is small and more rounded compared to other big cats. Saharan cheetahs have canine-like slim faces. The ears are small, short and rounded; they are tawny at the base and on the edges and marked with black patches on the back. The eyes are set high and have round pupils. The whiskers, shorter and fewer than those of other felids, are fine and inconspicuous. The pronounced tear streaks (or malar stripes), unique to the cheetah, originate from the corners of the eyes and run down the nose to the mouth. The role of these streaks is not well understood—they may protect the eyes from the sun's glare (a helpful feature as the cheetah hunts mainly during the day), or they could be used to define facial expressions. The exceptionally long and muscular tail, with a bushy white tuft at the end, measures 60–80 cm (24–31 in). While the first two-thirds of the tail are covered in spots, the final third is marked with four to six dark rings or stripes.The cheetah is superficially similar to the leopard, which has a larger head, fully retractable claws, rosettes instead of spots, lacks tear streaks and is more muscular. Moreover, the cheetah is taller than the leopard. The serval also resembles the cheetah in physical build, but is significantly smaller, has a shorter tail and its spots fuse to form stripes on the back. The cheetah appears to have evolved convergently with canids in morphology and behaviour; it has canine-like features such as a relatively long snout, long legs, a deep chest, tough paw pads and blunt, semi-retractable claws. The cheetah has often been likened to the greyhound, as both have similar morphology and the ability to reach tremendous speeds in a shorter time than other mammals, but the cheetah can attain much higher maximum speeds.
+
+
+=== Internal anatomy ===
+
+Sharply contrasting with the other big cats in its morphology, the cheetah shows several specialized adaptations for prolonged chases to catch prey at some of the fastest speeds reached by land animals. Its light, streamlined body makes it well-suited to short, explosive bursts of speed, rapid acceleration, and an ability to execute extreme changes in direction while moving at high speed. The large nasal passages, accommodated well due to the smaller size of the canine teeth, ensure fast flow of sufficient air, and the enlarged heart and lungs allow the enrichment of blood with oxygen in a short time. This allows cheetahs to rapidly regain their stamina after a chase. During a typical chase, their respiratory rate increases from 60 to 150 breaths per minute. Moreover, the reduced viscosity of the blood at higher temperatures (common in frequently moving muscles) could ease blood flow and increase oxygen transport. While running, in addition to having good traction due to their semi-retractable claws, cheetahs use their tail as a rudder-like means of steering that enables them to make sharp turns, necessary to outflank antelopes which often change direction to escape during a chase. The protracted claws increase grip over the ground, while rough paw pads make the sprint more convenient over tough ground. The limbs of the cheetah are longer than what is typical for other cats its size; the thigh muscles are large, and the tibia and fibula are held close together making the lower legs less likely to rotate. This reduces the risk of losing balance during runs, but compromises the cat's ability to climb trees. The highly reduced clavicle is connected through ligaments to the scapula, whose pendulum-like motion increases the stride length and assists in shock absorption. The extension of the vertebral column can add as much as 76 cm (30 in) to the stride length.
+
+The cheetah resembles the smaller cats in cranial features, and in having a long and flexible spine, as opposed to the stiff and short one in other large felids. The roughly triangular skull has light, narrow bones and the sagittal crest is poorly developed, possibly to reduce weight and enhance speed. The mouth can not be opened as widely as in other cats given the shorter length of muscles between the jaw and the skull. A study suggested that the limited retraction of the cheetah's claws may result from the earlier truncation of the development of the middle phalanx bone in cheetahs.The cheetah has a total of 30 teeth; the dental formula is 3.1.3.13.1.2.1. The sharp, narrow carnassials are larger than those of leopards and lions, suggesting the cheetah can consume larger amount of food in a given time period. The small, flat canines are used to bite the throat and suffocate the prey. A study gave the bite force quotient (BFQ) of the cheetah as 119, close to that for the lion (112), suggesting that adaptations for a lighter skull may not have reduced the power of the cheetah's bite. Unlike other cats, the cheetah's canines have no gap behind them when the jaws close, as the top and bottom cheek teeth show extensive overlap; this equips the upper and lower teeth to effectively tear through the meat. The slightly curved claws, shorter and straighter than those of other cats, lack a protective sheath and are partly retractable. The claws are blunt due to lack of protection, but the large and strongly curved dewclaw is remarkably sharp. Cheetahs have a high concentration of nerve cells arranged in a band in the centre of the eyes, a visual streak, the most efficient among felids. This significantly sharpens the vision and enables the cheetah to swiftly locate prey against the horizon. The cheetah is unable to roar due to the presence of a sharp-edged vocal fold within the larynx.
+
+
+=== Speed and acceleration ===
+
+The cheetah is the world's fastest land animal. Estimates of the maximum speed attained range from 80 to 128 km/h (50 to 80 mph). A commonly quoted value is 112 km/h (70 mph), recorded in 1957, but this measurement is disputed. In 2012, an 11-year-old cheetah (named Sarah) from the Cincinnati Zoo set a world record by running 100 m (330 ft) in 5.95 seconds over a set run, recording a maximum speed of 98 km/h (61 mph).Contrary to the common belief that cheetahs hunt by simply chasing its prey at high speeds, the findings of two studies in 2013 observing hunting cheetahs using GPS collars show that cheetahs hunt at speeds much lower than the highest recorded for them during most of the chase, interspersed with a few short bursts (lasting only seconds) when they attain peak speeds. In one of the studies, the average speed recorded during the high speed phase was 53.64 km/h (33.3 mph), or within the range 41.4–65.88 km/h (25.7–40.9 mph) including error. The highest recorded value was 93.24 km/h (57.9 mph). The researchers suggested that a hunt consists of two phases—an initial fast acceleration phase when the cheetah tries to catch up with the prey, followed by slowing down as it closes in on it, the deceleration varying by the prey in question. The peak acceleration observed was 2.5 m/s (8.2 ft/s), while the peak deceleration value was 7.5 m/s (25 ft/s). Speed and acceleration values for a hunting cheetah may be different from those for a non-hunter because while engaged in the chase, the cheetah is more likely to be twisting and turning and may be running through vegetation. The speeds attained by the cheetah may be only slightly greater than those achieved by the pronghorn at 88.5 km/h (55.0 mph) and the springbok at 88 km/h (55 mph), but the cheetah additionally has an exceptional acceleration.One stride of a galloping cheetah measures 4 to 7 m (13 to 23 ft); the stride length and the number of jumps increases with speed. During more than half the duration of the sprint, the cheetah has all four limbs in the air, increasing the stride length. Running cheetahs can retain up to 90% of the heat generated during the chase. A 1973 study suggested the length of the sprint is limited by excessive build-up of body heat when the body temperature reaches 40–41 °C (104–106 °F). However, a 2013 study recorded the average temperature of cheetahs after hunts to be 38.6 °C (101.5 °F), suggesting high temperatures need not cause hunts to be abandoned.The running speed of 71 mph (114 km/h) of the cheetah was obtained as an result of a single run of one individual by dividing the distance traveled for time spent. The run lasted 2.25 seconds and was supposed to have been 73 m (240 ft) long, but was later found to have been 59 m (194 ft) long. It was therefore discredited for a faulty method of measurement.
+Cheetahs have subsequently been measured at running at a speed of 64 mph (103 km/h) as an average of three runs including in opposite direction, for a single individual, over a marked 200 m (220 yd) course, even starting the run 18 m (59 ft) behind the start line, starting the run already running on the course. Again dividing the distance by time, but this time to determine the maximum sustained speed, completing the runs in an average time of 7 seconds. Being a more accurate method of measurement, this test was made in 1965 but published in 1997.
+Subsequently with GPS-IMU collars, running speed was measured for wild cheetahs during hunts with turns and maneuvers, and the maximum speed recorded was 58 mph (93 km/h) sustained for 1–2 seconds. The speed was obtained by dividing the length by the time between footfalls of a stride.
+
+
+== Ecology and behaviour ==
+Cheetahs are active mainly during the day, whereas other carnivores such as leopards and lions are active mainly at night; These larger carnivores can kill cheetahs and steal their kills; hence, the diurnal tendency of cheetahs helps them avoid larger predators in areas where they are sympatric, such as the Okavango Delta. In areas where the cheetah is the major predator (such as farmlands in Botswana and Namibia), activity tends to increase at night. This may also happen in highly arid regions such as the Sahara, where daytime temperatures can reach 43 °C (109 °F). The lunar cycle can also influence the cheetah's routine—activity might increase on moonlit nights as prey can be sighted easily, though this comes with the danger of encountering larger predators. Hunting is the major activity throughout the day, with peaks during dawn and dusk. Groups rest in grassy clearings after dusk. Cheetahs often inspect their vicinity at observation points such as elevations to check for prey or larger carnivores; even while resting, they take turns at keeping a lookout.
+
+
+=== Social organisation ===
+
+Cheetahs have a flexible and complex social structure and tend to be more gregarious than several other cats (except the lion). Individuals typically avoid one another but are generally amicable; males may fight over territories or access to females in oestrus, and on rare occasions such fights can result in severe injury and death. Females are not social and have minimal interaction with other individuals, barring the interaction with males when they enter their territories or during the mating season. Some females, generally mother and offspring or siblings, may rest beside one another during the day. Females tend to lead a solitary life or live with offspring in undefended home ranges; young females often stay close to their mothers for life but young males leave their mother's range to live elsewhere.Some males are territorial, and group together for life, forming coalitions that collectively defend a territory which ensures maximum access to females—this is unlike the behaviour of the male lion who mates with a particular group (pride) of females. In most cases, a coalition will consist of brothers born in the same litter who stayed together after weaning, but biologically unrelated males are often allowed into the group; in the Serengeti 30% members in coalitions are unrelated males. If a cub is the only male in a litter he will typically join an existing group, or form a small group of solitary males with two or three other lone males who may or may not be territorial. In the Kalahari Desert around 40% of the males live in solitude.Males in a coalition are affectionate toward each other, grooming mutually and calling out if any member is lost; unrelated males may face some aversion in their initial days in the group. All males in the coalition typically have equal access to kills when the group hunts together, and possibly also to females who may enter their territory. A coalition generally has a greater chance of encountering and acquiring females for mating, however, its large membership demands greater resources than do solitary males. A 1987 study showed that solitary and grouped males have a nearly equal chance of coming across females, but the males in coalitions are notably healthier and have better chances of survival than their solitary counterparts.
+
+
+=== Home ranges and territories ===
+Unlike many other felids, among cheetahs, females tend to occupy larger areas compared to males. Females typically disperse over large areas in pursuit of prey, but they are less nomadic and roam in a smaller area if prey availability in the area is high. As such, the size of their home range depends on the distribution of prey in a region. In central Namibia, where most prey species are sparsely distributed, home ranges average 554–7,063 km2 (214–2,727 sq mi), whereas in the woodlands of the Phinda Game Reserve (South Africa), which have plentiful prey, home ranges are 34–157 km2 (13–61 sq mi) in size. Cheetahs can travel long stretches overland in search of food; a study in the Kalahari Desert recorded an average displacement of nearly 11 km (6.8 mi) every day and walking speeds ranged between 2.5 and 3.8 km/h (1.6 and 2.4 mph).Males are generally less nomadic than females; often males in coalitions (and sometimes solitary males staying far from coalitions) establish territories. Whether males settle in territories or disperse over large areas forming home ranges depends primarily on the movements of females. Territoriality is preferred only if females tend to be more sedentary, which is more feasible in areas with plenty of prey. Some males, called floaters, switch between territoriality and nomadism depending on the availability of females. A 1987 study showed territoriality depended on the size and age of males and the membership of the coalition. The ranges of floaters averaged 777 km2 (300 sq mi) in the Serengeti to 1,464 km2 (565 sq mi) in central Namibia. In the Kruger National Park (South Africa) territories were much smaller. A coalition of three males occupied a territory measuring 126 km2 (49 sq mi), and the territory of a solitary male measured 195 km2 (75 sq mi). When a female enters a territory, the males will surround her; if she tries to escape, the males will bite or snap at her. Generally, the female can not escape on her own; the males themselves leave after they lose interest in her. They may smell the spot she was sitting or lying on to determine if she was in oestrus.
+
+
+=== Communication ===
+
+The cheetah is a vocal felid with a broad repertoire of calls and sounds; the acoustic features and the use of many of these have been studied in detail. The vocal characteristics, such as the way they are produced, are often different from those of other cats. For instance, a study showed that exhalation is louder than inhalation in cheetahs, while no such distinction was observed in the domestic cat. Listed below are some commonly recorded vocalisations observed in cheetahs:
+
+Chirping: A chirp (or a "stutter-bark") is an intense bird-like call and lasts less than a second. Cheetahs chirp when they are excited, for instance, when gathered around a kill. Other uses include summoning concealed or lost cubs by the mother, or as a greeting or courtship between adults. The cheetah's chirp is similar to the soft roar of the lion, and its churr as the latter's loud roar. A similar but louder call ('yelp') can be heard from up to 2 km (1.2 mi) away; this call is typically used by mothers to locate lost cubs, or by cubs to find their mothers and siblings.
+Churring (or churtling): A churr is a shrill, staccato call that can last up to two seconds. Churring and chirping have been noted for their similarity to the soft and loud roars of the lion. It is produced in similar context as chirping, but a study of feeding cheetahs found chirping to be much more common.
+Purring: Similar to purring in domestic cats but much louder, it is produced when the cheetah is content, and as a form of greeting or when licking one another. It involves continuous sound production alternating between egressive and ingressive airstreams.
+Agonistic sounds: These include bleating, coughing, growling, hissing, meowing and moaning (or yowling). A bleat indicates distress, for instance when a cheetah confronts a predator that has stolen its kill. Growls, hisses and moans are accompanied by multiple, strong hits on the ground with the front paw, during which the cheetah may retreat by a few metres. A meow, though a versatile call, is typically associated with discomfort or irritation.
+Other vocalisations: Individuals can make a gurgling noise as part of a close, amicable interaction. A "nyam nyam" sound may be produced while eating. Apart from chirping, mothers can use a repeated "ihn ihn" is to gather cubs, and a "prr prr" is to guide them on a journey. A low-pitched alarm call is used to warn the cubs to stand still. Bickering cubs can let out a "whirr"—the pitch rises with the intensity of the quarrel and ends on a harsh note.Another major means of communication is by scent—the male will often investigate urine-marked places (territories or common landmarks) for a long time by crouching on his forelegs and carefully smelling the place. Then he will raise his tail and urinate on an elevated spot (such as a tree trunk, stump or rock); other observing individuals might repeat the ritual. Females may also show marking behaviour but less prominently than males do. Among females, those in oestrus will show maximum urine-marking, and their excrement can attract males from far off. In Botswana, cheetahs are frequently captured by ranchers to protect livestock by setting up traps in traditional marking spots; the calls of the trapped cheetah can attract more cheetahs to the place.Touch and visual cues are other ways of signalling in cheetahs. Social meetings involve mutual sniffing of the mouth, anus and genitals. Individuals will groom one another, lick each other's faces and rub cheeks. However, they seldom lean on or rub their flanks against each other. The tear streaks on the face can sharply define expressions at close range. Mothers probably use the alternate light and dark rings on the tail to signal their cubs to follow them.
+
+
+=== Diet and hunting ===
+
+The cheetah is a carnivore that hunts small to medium-sized prey weighing 20 to 60 kg (44 to 132 lb), but mostly less than 40 kg (88 lb). Its primary prey are medium-sized ungulates. They are the major component of the diet in certain areas, such as Dama and Dorcas gazelles in the Sahara, impala in the eastern and southern African woodlands, springbok in the arid savannas to the south and Thomson's gazelle in the Serengeti. Smaller antelopes like the common duiker are a frequent prey in the southern Kalahari. Larger ungulates are typically avoided, though nyala, whose males weigh around 120 kg (260 lb), were found to be the major prey in a study in the Phinda Game Reserve. In Namibia cheetahs are the major predators of livestock. The diet of the Asiatic cheetah consists of chinkara, desert hare, goitered gazelle, urial, wild goats and livestock; in India cheetahs used to prey mostly on blackbuck. There are no records of cheetahs killing humans. Cheetahs in the Kalahari have been reported feeding on citron melons for their water content.Prey preferences and hunting success vary with the age, sex and number of cheetahs involved in the hunt and on the vigilance of the prey. Generally only groups of cheetahs (coalitions or mother and cubs) will try to kill larger prey; mothers with cubs especially look out for larger prey and tend to be more successful than females without cubs. Individuals on the periphery of the prey herd are common targets; vigilant prey which would react quickly on seeing the cheetah are not preferred.Cheetahs hunt primarily throughout the day, sometimes with peaks at dawn and dusk; they tend to avoid larger predators like the primarily nocturnal lion. Cheetahs in the Sahara and Maasai Mara in Kenya hunt after sunset to escape the high temperatures of the day. Cheetahs use their vision to hunt instead of their sense of smell; they keep a lookout for prey from resting sites or low branches. The cheetah will stalk its prey, trying to conceal itself in cover, and approach as close as possible, often within 60 to 70 m (200 to 230 ft) of the prey (or even farther for less alert prey). Alternatively the cheetah can lie hidden in cover and wait for the prey to come nearer. A stalking cheetah assumes a partially crouched posture, with the head lower than the shoulders; it will move slowly and be still at times. In areas of minimal cover the cheetah will approach within 200 m (660 ft) of the prey and start the chase. The chase typically lasts a minute; in a 2013 study, the length of chases averaged 173 m (568 ft), and the longest run measured 559 m (1,834 ft). The cheetah can give up the chase if it is detected by the prey early or if it can not make a kill quickly. Cheetahs catch their prey by tripping it during the chase by hitting its rump with the forepaw or using the strong dewclaw to knock the prey off its balance, bringing it down with much force and sometimes even breaking some of its limbs.Cheetahs can decelerate dramatically towards the end of the hunt, slowing down from 93 km/h (58 mph) to 23 km/h (14 mph) in just three strides, and can easily follow any twists and turns the prey makes as it tries to flee. To kill medium- to large-sized prey, the cheetah bites the prey's throat to suffocate it, maintaining the bite for around five minutes, within which the prey stops struggling. A bite on the nape of the neck or the snout (and sometimes on the skull) suffices to kill smaller prey. Cheetahs have an average hunting success rate of 25–40%, higher for smaller and more vulnerable prey.Once the hunt is over, the prey is taken near a bush or under a tree; the cheetah, highly exhausted after the chase, rests beside the kill and pants heavily for five to 55 minutes. Meanwhile, cheetahs nearby, who did not take part in the hunt, might feed on the kill immediately. Groups of cheetah devour the kill peacefully, though minor noises and snapping may be observed. Cheetahs can consume large quantities of food; a cheetah at the Etosha National Park (Namibia) was found to consume as much as 10 kg (22 lb) within two hours. However, on a daily basis, a cheetah feeds on around 4 kg (8.8 lb) meat. Cheetahs, especially mothers with cubs, remain cautious even as they eat, pausing to look around for fresh prey or for predators who may steal the kill.Cheetahs move their heads from side to side so the sharp carnassial teeth tear the flesh, which can then be swallowed without chewing. They typically begin with the hindquarters, and then progress toward the abdomen and the spine. Ribs are chewed on at the ends, and the limbs are not generally torn apart while eating. Unless the prey is very small, the skeleton is left almost intact after feeding on the meat. Cheetahs might lose 10–15% of their kills to large carnivores such as hyenas and lions (and grey wolves in Iran). To defend itself or its prey, a cheetah will hold its body low to the ground and snarl with its mouth wide open, the eyes staring threateningly ahead and the ears folded backward. This may be accompanied by moans, hisses and growls, and hitting the ground with the forepaws. Cheetahs have rarely been observed scavenging kills; this may be due to vultures and spotted hyena adroitly capturing and consuming heavy carcasses within a short time.
+
+
+=== Reproduction and life cycle ===
+
+Cheetahs are induced ovulators and can breed throughout the year. Females can have their first litter at two to three years of age. Polyestrous, females have an oestrus ("heat") cycle is 12 days long on average, but it can vary from three days to a month. A female can conceive again after 17 to 20 months from giving birth, or even sooner if a whole litter is lost. Males can breed at less than two years of age in captivity, but this may be delayed in the wild until the male acquires a territory. A 2007 study showed that females who gave birth to more litters early in their life often died younger, indicating a trade-off between longevity and yearly reproductive success.Urine-marking in males can become more pronounced when a female in their vicinity comes into oestrus. Males, sometimes even those in coalitions, fight among one another to secure access to the female. Often one male will eventually win dominance over the others and mate with the female, though a female can mate with different males. Mating begins with the male approaching the female, who lies down on the ground; individuals often chirp, purr or yelp at this time. No courtship behaviour is observed; the male immediately secures hold of the female's nape, and copulation takes place. The pair then ignore each other, but meet and copulate a few more times three to five times a day for the next two to three days before finally parting ways.After a gestation of nearly three months, a litter of one to eight cubs is born (though those of three to four cubs are more common). Births take place at 20–25 minute intervals in a sheltered place such as thick vegetation. The eyes are shut at birth, and open in four to 11 days. Newborn cubs might spit a lot and make soft churring noises; they start walking by two weeks. Their nape, shoulders and back are thickly covered with long bluish grey hair, called a mantle, which gives them a mohawk-type appearance; this fur is shed as the cheetah grows older. A study suggested that this mane gives a cheetah cub the appearance of a honey badger, and could act as camouflage from attacks by these badgers or predators that tend to avoid them.Compared to other felids, cheetah cubs are highly vulnerable to several predators during the first few weeks of their life. Mothers keep their cubs hidden in dense vegetation for the first two months and nurse in the early morning. The mother is extremely vigilant at this stage; she stays within 1 km (0.62 mi) of the lair, frequently visits her cubs, moves them every five to six days, and remains with them after dark. Despite trying to make minimal noise, she cannot generally defend her litter from predators. Predation is the leading cause of mortality in cheetah cubs; a study showed that in areas with a low density of predators (such as Namibian farmlands) around 70% of the cubs make it beyond the age of 14 months, whereas in areas like the Serengeti National Park, where several large carnivores exist, the survival rate was just 17%. Deaths also occur from starvation if their mothers abandon them, fires, or pneumonia because of exposure to bad weather. Generation length of the cheetah is six years.Cubs start coming out of the lair at two months of age, trailing after their mother wherever she goes. At this point the mother nurses less and brings solid food to the cubs; they retreat away from the carcass in fear initially, but gradually start eating it. The cubs might purr as the mother licks them clean after the meal. Weaning occurs at four to six months. To train her cubs in hunting, the mother will catch and let go of live prey in front of her cubs. Cubs' play behaviour includes chasing, crouching, pouncing and wrestling; there is plenty of agility, and attacks are seldom lethal. Playing can improve catching skills in cubs, though the ability to crouch and hide may not develop remarkably.Cubs as young as six months try to capture small prey like hares and young gazelles. However, they may have to wait until as long as 15 months of age to make a successful kill on their own. At around 20 months, offspring become independent; mothers might have conceived again by then. Siblings may remain together for a few more months before parting ways. While females stay close to their mothers, males move farther off. The lifespan of wild cheetahs is 14 to 15 years for females, and their reproductive cycle typically ends by 12 years of age; males generally live as long as ten years.
+
+
+== Distribution and habitat ==
+
+Cheetahs appear to be less selective in habitat choice than other felids and inhabit a variety of ecosystems; areas with greater availability of prey, good visibility and minimal chances of encountering larger predators are preferred. They seldom occur in tropical forests. Cheetahs have been reported at elevations as high as 4,000 m (13,000 ft). An open area with some cover, such as diffused bushes, is probably ideal for the cheetah because it needs to stalk and pursue its prey over a distance. This also minimises the risk of encountering larger carnivores. Unlike the big cats, the cheetah tends to occur in low densities typically between 0.3 and 3.0 adults per 100 km2 (39 sq mi)—these values are 10–30% of those reported for leopards and lions.Cheetahs in eastern and southern Africa occur mostly in savannas like the Kalahari and Serengeti. In central, northern and western Africa cheetahs inhabit arid mountain ranges and valleys; in the harsh climate of the Sahara, cheetahs prefer high mountains, which receive more rainfall than the surrounding desert. The vegetation and water resources in these mountains supports antelopes. Iranian cheetahs occur in hilly terrain of deserts at elevations up to 2,000–3,000 m (6,600–9,800 ft), where annual precipitation is generally below 100 mm (3.9 in); the primary vegetation in these areas is thinly distributed shrubs, less than 1 m (3 ft 3 in) tall.
+
+
+=== Historical range ===
+
+In prehistoric times, the cheetah was distributed throughout Africa, Asia and Europe. It gradually fell to extinction in Europe, possibly because of competition with the lion. Today the cheetah has been extirpated in most of its historical range; the numbers of the Asiatic cheetah had begun plummeting since the late 1800s, long before the other subspecies started their decline. As of 2017, cheetahs occur in just nine per cent of their erstwhile range in Africa, mostly in unprotected areas.In the past until the mid-20th century, the cheetah ranged across vast stretches in Asia, from the Arabian Peninsula in the west to the Indian subcontinent in the east, and as far north as the Aral and Caspian Seas. A few centuries ago the cheetah was abundant in India, and its range coincided with the distribution of major prey like the blackbuck. However, its numbers in India plummeted from the 19th century onward; Divyabhanusinh of the Bombay Natural History Society notes that the last three individuals in the wild were killed by Maharaja Ramanuj Pratap Singh of Surguja (a man also noted for holding a record for shooting 1,360 tigers) in 1947. The last confirmed sighting in India was of a cheetah that drowned in a well near Hyderabad in 1957. In Iran there were around 400 cheetahs before World War II, distributed across deserts and steppes to the east and the borderlands with Iraq to the west; the numbers were falling because of a decline in prey. In Iraq, cheetahs were reported from Basra in the 1920s. Conservation efforts in the 1950s stabilised the population, but prey species declined again in the wake of the Iranian Revolution (1979) and the Iran–Iraq War (1980–1988), leading to a significant contraction of the cheetah's historical range in the region.The first survey of cheetah populations in Africa by Norman Myers in 1975 estimated a population of 15,000 individuals throughout Sub-Saharan Africa. The range covered most of eastern and southern Africa, except for the desert region on the western coast of modern-day Angola and Namibia. In the following years, as their natural habitat has been modified dramatically, cheetah populations across the region have become smaller and more fragmented.
+
+
+=== Present distribution ===
+The cheetah occurs mostly in eastern and southern Africa; its presence in Asia is limited to the central deserts of Iran, though there have been unconfirmed reports of sightings in Afghanistan, Iraq and Pakistan in the last few decades. The global population of cheetahs was estimated at nearly 7,100 mature individuals in 2016. The Iranian population appears to have decreased from 60 to 100 individuals in 2007 to 43 in 2016, distributed in three subpopulations over less than 150,000 km2 (58,000 sq mi) in Iran's central plateau. The largest population of nearly 4,000 individuals is sparsely distributed over Angola, Botswana, Mozambique, Namibia, South Africa and Zambia. Another population in Kenya and Tanzania comprises about 1,000 individuals. All other cheetahs occur in small, fragmented groups of less than 100 individuals each. Populations are feared to be declining.
+
+
+== Threats ==
+The cheetah is threatened by several factors, like habitat loss and fragmentation of populations. Habitat loss is caused mainly by the introduction of commercial land use, such as agriculture and industry. It is further aggravated by ecological degradation, like bush encroachment, which is common in southern Africa. Moreover, the species apparently requires a sizeable area to live in as indicated by its low population densities. Shortage of prey and conflict with other species such as humans and large carnivores are other major threats. The cheetah appears to be less capable of coexisting with humans than the leopard. With 76% of its range consisting of unprotected land, the cheetah is often targeted by farmers and pastoralists who attempt to protect their livestock, especially in Namibia. Illegal wildlife trade and trafficking is another problem in some places (like Ethiopia). Some tribes, like the Maasai people in Tanzania, have been reported to use cheetah skins in ceremonies. Roadkill is another threat, especially in areas where roads have been constructed near natural habitat or protected areas. Cases of roadkill involving cheetahs have been reported from Kalmand, Touran National Park, and Bafq in Iran. The reduced genetic variability makes cheetahs more vulnerable to diseases; however, the threat posed by infectious diseases may be minor, given the low population densities and hence a reduced chance of infection.
+
+
+== Conservation ==
+The cheetah has been classified as Vulnerable by the IUCN; it is listed under Appendix I of the CMS and Appendix I of CITES. The Endangered Species Act enlists the cheetah as Endangered.
+
+
+=== In Africa ===
+
+Until the 1970s, cheetahs and other carnivores were frequently killed to protect livestock in Africa. Gradually the understanding of cheetah ecology increased and their falling numbers became a matter of concern. The De Wildt Cheetah and Wildlife Centre was set up in 1971 in South Africa to provide care for wild cheetahs regularly trapped or injured by Namibian farmers. By 1987, the first major research project to outline cheetah conservation strategies was underway. The Cheetah Conservation Fund, founded in 1990 in Namibia, put efforts into field research and education about cheetahs on the global platform. The CCF runs a cheetah genetics laboratory, the only one of its kind, in Otjiwarongo (Namibia); "Bushblok" is an initiative to restore habitat systematically through targeted bush thinning and biomass utilisation. Several more cheetah-specific conservation programmes have since been established, like Cheetah Outreach in South Africa.The Global Cheetah Action Plan Workshop in 2002 laid emphasis on the need for a rangewide survey of wild cheetahs to demarcate areas for conservation efforts and on creating awareness through training programs. The Range Wide Conservation Program for Cheetah and African Wild Dogs (RWCP) began in 2007 as a joint initiative of the IUCN Cat and Canid Specialist Groups, the Wildlife Conservation Society and the Zoological Society of London. National conservation plans have been developed successfully for several African countries. In 2014, the CITES Standing Committee recognised the cheetah as a "species of priority" in their strategies in northeastern Africa to counter wildlife trafficking. In December 2016 the results of an extensive survey detailing the distribution and demography of cheetahs throughout the range were published; the researchers recommended listing the cheetah as Endangered on the IUCN Red List.The cheetah was reintroduced in Malawi in 2017.
+
+
+=== In Asia ===
+
+In 2001, the Iranian government collaborated with the CCF, the IUCN, Panthera Corporation, UNDP and the Wildlife Conservation Society on the Conservation of Asiatic Cheetah Project (CACP) to protect the natural habitat of the Asiatic cheetah and its prey. In 2004, the Iranian Centre for Sustainable Development (CENESTA) conducted an international workshop to discuss conservation plans with local stakeholders. Iran declared 31 August as National Cheetah Day in 2006. The Iranian Cheetah Strategic Planning meet in 2010 formulated a five-year conservation plan for Asiatic cheetahs. The CACP Phase II was implemented in 2009, and the third phase was drafted in 2018.During the early 2000s scientists from the Centre for Cellular and Molecular Biology (Hyderabad) proposed a plan to clone Asiatic cheetahs from Iran for reintroduction in India, but Iran denied the proposal. In September 2009, the Minister of Environment and Forests assigned the Wildlife Trust of India and the Wildlife Institute of India with examining the potential of importing African cheetahs to India. Kuno Wildlife Sanctuary and Nauradehi Wildlife Sanctuary were suggested as reintroduction sites for the cheetah because of their high prey density. However, plans for reintroduction were stalled in May 2012 by the Supreme Court of India because of a political dispute and concerns over introducing a non-native species to the country. Opponents stated the plan was "not a case of intentional movement of an organism into a part of its native range". On 28 January 2020, the Supreme Court allowed the central government to introduce cheetahs to a suitable habitat in India on an experimental basis to see if they can adapt to it. In July 2022, it was announced that eight cheetahs would be transferred from Namibia to India in August. In 2020, India signed a memorandum of understanding with Namibia as part of Project Cheetah. Eight cheetahs have been donated by Namibia that will be introduced to the Kuno National Park. The eight cheetahs were released into Kuno on September 17th, 2022 by Prime Minister Narendra Modi.

+
+== Interaction with humans ==
+
+
+=== Taming ===
+The cheetah shows little aggression toward humans, and can be tamed easily, as it has been since antiquity. The earliest known depictions of the cheetah are from the Chauvet Cave in France, dating back to 32,000–26,000 BC. According to historians such as Heinz Friederichs and Burchard Brentjes, the cheetah was first tamed in Sumer and this gradually spread out to central and northern Africa, from where it reached India. The evidence for this is mainly pictorial; for instance, a Sumerian seal dating back to c. 3000 BC, featuring a long-legged leashed animal has fueled speculation that the cheetah was first tamed in Sumer. However, Thomas Allsen argues that the depicted animal might be a large dog. Other historians, such as Frederick Zeuner, have opined that ancient Egyptians were the first to tame the cheetah, from where it gradually spread into central Asia, Iran and India.In comparison, theories of the cheetah's taming in Egypt are stronger and include timelines proposed on this basis. Mafdet, one of the ancient Egyptian deities worshiped during the First Dynasty (3100–2900 BC), was sometimes depicted as a cheetah. Ancient Egyptians believed the spirits of deceased pharaohs were taken away by cheetahs. Reliefs in the Deir el-Bahari temple complex tell of an expedition by Egyptians to the Land of Punt during the reign of Hatshepsut (1507–1458 BC) that fetched, among other things, animals called "panthers". During the New Kingdom (16th to 11th centuries BC), cheetahs were common pets for royalty, who adorned them with ornate collars and leashes. The Egyptians would use their dogs to bring the concealed prey out in the open, after which a cheetah would be set upon it to kill it. Rock carvings depicting cheetahs dating back to 2000–6000 years ago have been found in Twyfelfontein; little else has been discovered in connection to the taming of cheetahs (or other cats) in southern Africa.Hunting cheetahs are known in pre-Islamic Arabic art from Yemen. Hunting with cheetahs became more prevalent toward the seventh century AD. In the Middle East, the cheetah would accompany the nobility to hunts in a special seat on the back of the saddle. Taming was an elaborate process and could take a year to complete. The Romans may have referred to the cheetah as the leopardos (λεοπάρδος) or leontopardos (λεοντόπαρδος), believing it to be a hybrid between a leopard and a lion because of the mantle seen in cheetah cubs and the difficulty of breeding them in captivity. A Roman hunting cheetah is depicted in a 4th century mosaic from Lod, Israel. Cheetahs continued to be used into the Byzantine period of the Roman empire, with "hunting leopards" being mentioned in the Cynegetica (283/284 AD).In eastern Asia, records are confusing as regional names for the leopard and the cheetah may be used interchangeably. The earliest depiction of cheetahs from eastern Asia dates back to the Tang dynasty (7th to 10th centuries AD); paintings depict tethered cheetahs and cheetahs mounted on horses. Chinese emperors would use cheetahs and caracals as gifts. In the 13th and the 14th centuries, the Yuan rulers bought numerous cheetahs from the western parts of the empire and from Muslim merchants. According to the Ming Shilu, the subsequent Ming dynasty (14th to 17th centuries) continued this practice. Tomb figurines from the Mongol empire, dating back to the reign of Kublai Khan (1260–1294 AD), represent cheetahs on horseback. The Mughal ruler Akbar the Great (1556–1605 AD) is said to have kept as many as 1000 khasa (imperial) cheetahs. His son Jahangir wrote in his memoirs, Tuzk-e-Jahangiri, that only one of them gave birth. Mughal rulers trained cheetahs and caracals in a similar way as the western Asians, and used them to hunt game, especially blackbuck. The rampant hunting severely affected the populations of wild animals in India; by 1927, cheetahs had to be imported from Africa.
+
+		
+
+
+=== In captivity ===
+
+The first cheetah to be brought into captivity in a zoo was at the Zoological Society of London in 1829. Early captive cheetahs showed a high mortality rate, with an average lifespan of 3–4 years. After trade of wild cheetahs was delimited by the enforcement of CITES in 1975, more efforts were put into breeding in captivity; in 2014 the number of captive cheetahs worldwide was estimated at 1730 individuals, with 87% born in captivity.Mortality under captivity is generally high; in 2014, 23% of the captive cheetahs worldwide died under one year of age, mostly within a month of birth. Deaths result from several reasons—stillbirths, birth defects, cannibalism, hypothermia, maternal neglect, and infectious diseases. Compared to other felids, cheetahs need specialised care because of their higher vulnerability to stress-induced diseases; this has been attributed to their low genetic variability and factors of captive life. Common diseases of cheetahs include feline herpesvirus, feline infectious peritonitis, gastroenteritis, glomerulosclerosis, leukoencephalopathy, myelopathy, nephrosclerosis and veno-occlusive disease. High density of cheetahs in a place, closeness to other large carnivores in enclosures, improper handling, exposure to public and frequent movement between zoos can be sources of stress for cheetahs. Recommended management practices for cheetahs include spacious and ample access to outdoors, stress minimisation by exercise and limited handling, and following proper hand-rearing protocols (especially for pregnant females).Wild cheetahs are far more successful breeders than captive cheetahs; this has also been linked to increased stress levels in captive individuals. In a study in the Serengeti, females were found to have a 95% success rate in breeding, compared to 20% recorded for North American captive cheetahs in another study. On 26 November 2017, a female cheetah gave birth to eight cubs in the Saint Louis Zoo, setting a record for the most births recorded by the Association of Zoos and Aquariums. Chances of successful mating in captive males can be improved by replicating social groups such as coalitions observed in the wild.
+
+
+=== In culture ===
+
+The cheetah has been widely portrayed in a variety of artistic works. In Bacchus and Ariadne, an oil painting by the 16th-century Italian painter Titian, the chariot of the Greek god Dionysus (Bacchus) is depicted as being drawn by two cheetahs. The cheetahs in the painting were previously considered to be leopards. In 1764, English painter George Stubbs commemorated the gifting of a cheetah to George III by the English Governor of Madras, Sir George Pigot in his painting Cheetah with Two Indian Attendants and a Stag. The painting depicts a cheetah, hooded and collared by two Indian servants, along with a stag it was supposed to prey upon. The 1896 painting The Caress by the 19th-century Belgian symbolist painter Fernand Khnopff is a representation of the myth of Oedipus and the Sphinx and portrays a creature with a woman's head and a cheetah's body.

Hussein, An Entertainment, a novel by Patrick O'Brian set in the British Raj period in India, illustrates the practice of royalty keeping and training cheetahs to hunt antelopes. The book How It Was with Dooms tells the true story of a family raising an orphaned cheetah cub named Dooms in Kenya. The 2005 film Duma was based loosely on this book. The animated series ThunderCats had a character named "Cheetara", an anthropomorphic cheetah, voiced by Lynne Lipton. Comic book heroine Wonder Woman's chief adversary is Barbara Ann Minerva alias The Cheetah.The Bill Thomas Cheetah American racing car, a Chevrolet-based coupe first designed and driven in 1963, was an attempt to challenge Carroll Shelby's Shelby Cobra in American sports car competition of the 1960s. Because only two dozen or fewer chassis were built, with only a dozen complete cars, the Cheetah was never homologated for competition beyond prototype status; its production ended in 1966. In 1986, Frito-Lay introduced Chester Cheetah, an anthropomorphic cheetah, as the mascot for their snack food Cheetos. The Mac OS X 10.0 was code-named "Cheetah".

+Acrantophis dumerili, commonly known as Dumeril's boa, is a species of non-venomous snake in the family Boidae. The species is endemic to  Madagascar. There are no subspecies that are recognized as being valid.
+
+
+== Etymology ==
+The specific name, dumerili, is in honor of French herpetologist André Marie Constant Duméril.
+
+
+== Description ==
+Adults of A. dumerili usually grow to 6.5 feet (2 m) in total length (including tail) with the maximum reported to be 8 foot, 6 inches (259 cm). Males usually have longer skinnier tails, while females tend to be larger overall.The color pattern consists of a gray-brown ground color with darker patches, forming an effective camouflage against the leaf litter of the forest floor of their native habitat.
+
+		
+		
+
+
+== Distribution and habitat ==
+A. dumerili is found on Madagascar. The type locality given in the original description is "Amérique mérid. ?", which is later given as "?" by Jan (1863).Along the western coast and southwestern regions of Madagascar, it is found in a semi-arid habitat that gets fairly low amounts of precipitation.
+
+
+== Conservation status ==
+The species A. dumerili is classified as Least Concern (LC) on the IUCN Red List for the following criteria: A1cd (v2.3, 1994). This means that a population reduction of at least 20% has been observed, estimated, inferred or suspected over the last 10 years or three generations, whichever is the longer, based on a decline in area of occupancy, extent of occurrence and/or quality of habitat, and based on actual or potential levels of exploitation. The species was last assessed in 2011.A. dumerili is also listed as CITES Appendix I, which means that it is threatened with extinction and CITES prohibits international trade except when the purpose of the import is not commercial, for example for scientific research.It is threatened by deforestation and human persecution. In some areas it is feared and often killed on sight. Although some native lore would relate stories of the souls of the tribes ancestors being in the snake skins, because patterns of faces on the sides of the snakes are interpreted, making them religiously sacred and therefore not dangerous to some cultures.
+
+
+== Feeding ==
+The diet of A. dumerili consists of small animals, such as birds, lizards, and small mammals, including juvenile lemurs. It is also known to prey on other snakes.
+
+
+== Reproduction ==
+In A. dumerili sexual maturity is reached within 3 to 5 years of age. Males have anal spurs, which are used in courtship.
+The mating season is March through May, and the young are born some 6 to 8 months later. Ovoviviparous, females give birth to a litters of 6-28. Neonates are 12-18 inches (30–46 cm) long.
+
+
+== Captivity ==
+Once exported from Madagascar in great numbers, trade in A. dumerili has since been heavily restricted. The species is, however, quite prolific in captivity, and captive bred individuals are easy to find in the Exotic pet trade. Though its size makes it more suited to someone experienced with large constrictors, it has a typically docile nature, and readily feeds on rats. The main concern is that it is prone to stress, which can sometimes cause it to stop eating or can contribute to other health issues.

+The addax (Addax nasomaculatus), also known as the white antelope and the screwhorn antelope, is an antelope native to the Sahara Desert. The only member of the genus Addax, it was first described scientifically by Henri de Blainville in 1816. As suggested by its alternative name, the pale antelope has long, twisted horns – typically 55 to 80 cm (22 to 31 in) in females and 70 to 85 cm (28 to 33 in) in males. Males stand from 105 to 115 cm (41 to 45 in) at the shoulder, with females at 95 to 110 cm (37 to 43 in). They are sexually dimorphic, as the females are smaller than the males. The colour of the coat depends on the season – in the winter, it is greyish-brown with white hindquarters and legs, and long, brown hair on the head, neck, and shoulders; in the summer, the coat turns almost completely white or sandy blonde.
+The addax mainly eats grasses and leaves of any available shrubs, leguminous herbs and bushes. They are well-adapted to exist in their desert habitat, as they can live without water for long periods of time. Addax form herds of five to 20 members, consisting of both males and females. They are led by the oldest female. Due to its slow movements, the addax is an easy target for its predators: humans, lions, leopards, cheetahs and African wild dogs. Breeding season is at its peak during winter and early spring. The natural habitat of the addax are arid regions, semideserts and sandy and stony deserts.
+The addax is a critically endangered species of antelope, as classified by the IUCN. Although extremely rare in its native habitat due to unregulated hunting, it is quite common in captivity. The addax was once abundant in North Africa; however it is currently only native to Chad, Mauritania, and Niger. It is extirpated from Algeria, Egypt, Libya, Sudan, and Western Sahara, but has been reintroduced into Morocco and Tunisia.
+
+
+== Taxonomy and naming ==
+The scientific name of the addax is Addax nasomaculatus. This antelope was first described by French zoologist and anatomist Henri Blainville in 1816. It is placed in the monotypic genus Addax and the family Bovidae. Henri Blainville observed syntypes in Bullock's Pantherion and the Museum of the Royal College of Surgeons. English naturalist Richard Lydekker stated their type locality to be probably Senegambia, though he did not have anything to support the claim. Finally, from a discussion in 1898, it became more probable that British hunters or collectors obtained the addax from the part of the Sahara in Tunisia.The generic name Addax is thought to be obtained from an Arabic word meaning a wild animal with crooked horns. It is also thought to have originated from a Latin word. The name was first used in 1693. The specific name nasomaculatus comes from the Latin words nasus (or the prefix naso-) meaning nose, and maculatus meaning spotted, referring to the spots and facial markings of the species. Bedouins use another name for the addax, the Arabic bakr (or bagr) al wahsh, which literally means "the cow of the wild". That name can be used to refer to other ungulates as well. The other common names of addax are "white antelope" and "screwhorn antelope".
+
+
+== Genetics ==
+The addax has 29 pairs of chromosomes. All chromosomes are acrocentric except for the first pair of autosomes, which are submetacentric. The X chromosome is the largest of the acrocentric chromosomes, and the Y chromosome is medium-sized. The short and long arms of the pair of submetacentric autosomes correspond respectively to the 27th and 1st chromosomes in cattle and goats. In a study, the banding patterns of chromosomes in addax were found to be similar to those in four other species of the subfamily Hippotraginae.
+
+
+== History and fossil record ==
+In ancient times, the addax occurred from northern Africa through Arabia and the Levant. Pictures in a tomb, dating back to 2500 BCE, show at least the partial domestication of the addax by the ancient Egyptians. These pictures show addax and some other antelopes tied with ropes to stakes. The number of addax captured by a person were considered an indicator of his high social and economic position in the society. The pygarg ("white-buttocked") beast mentioned in Deuteronomy 14:5 is believed to have been an addax. But today, excess poaching has resulted in the extinction of this species in Egypt since the 1960s.Addax fossils have been found in four sites of Egypt – a 7000 BCE fossil from the Great Sand Sea, a 5000–6000 BCE fossil from Djara, a 4000–7000 BCE fossil from Abu Ballas Stufenmland and a 5000 BCE fossil from Gilf Kebir. Apart from these, fossils have also been excavated from Mittleres Wadi Howar (6300 BCE fossil), and Pleistocene fossils from Grotte Neandertaliens, Jebel Irhoud and Parc d'Hydra.
+
+
+== Physical description ==
+ 
+The addax is a spiral-horned antelope. Male addaxes stand from 105 to 115 cm (41 to 45 in) at the shoulder, with females at 95 to 110 cm (37 to 43 in). They are sexually dimorphic, as the females are smaller than the males. The head and body length in both sexes is  120 to 130 cm (47 to 51 in), with a 25 to 35 cm (9.8 to 13.8 in) long tail. The weight of males varies from 100 to 125 kg (220 to 276 lb), and that of females from 60 to 90 kg (130 to 200 lb).The coloring of the addax's coat varies with the season. In the winter, it is greyish-brown with white hindquarters and legs, and long, brown hair on the head, neck, and shoulders. In the summer, the coat turns almost completely white or sandy blonde. Their head is marked with brown or black patches that form an 'X' over their noses. They have scraggly beards and prominent red nostrils. Long, black hairs stick out between their curved and spiralling horns, ending in a short mane on the neck.
+
+The horns, which are found on both males and females, have two to three twists and are typically 55 to 80 cm (22 to 31 in) in females and 70 to 85 cm (28 to 33 in) in males, although the maximum recorded length is 109.2 cm (43.0 in). The lower and middle portions of the horns are marked with a series of 30 to 35 ring-shaped ridges. The tail is short and slender, ending in a puff of black hair. The hooves are broad with flat soles and strong dewclaws to help them walk on soft sand. All four feet possess scent glands. The life span of the addax is up to 19 years in the wild, which can be extended to 25 years under captivity.The addax closely resembles the scimitar oryx, but can be distinguished by its horns and facial markings. While the addax is spiral-horned, the scimitar oryx has decurved 127 cm (50 in) long horns. The addax has a brown hair tuft extending from the base of its horns to between its eyes. A white patch, continuing from the brown hair, extends until the middle of the cheek. On the other hand, the scimitar oryx has a white forehead with only a notable brown marking: a brown lateral stripe across its eyes. It differs from other antelopes by having large, square teeth like cattle and lacking the typical facial glands.

+
+
+=== Parasites ===
+The addax is most prone to parasites in moist climatic conditions. Addaxes have always been infected with nematodes in the Trichostrongyloidea and Strongyloidea superfamilies. In an exotic ranch in Texas, an addax was found host to the nematodes Haemonchus contortus and Longistrongylus curvispiculum in its abomasum, of which the former was dominant.
+
+
+== Behavior and ecology ==
+These animals are mainly nocturnal, particularly in summer. In the day, they dig into the sand in shady locations and rest in these depressions, which also protect them from sandstorms. Addax herds contain both males and females, and have from five to 20 members. They will generally stay in one place and only wander widely in search of food. The addax has a strong social structure, probably based on age, and herds are led by the oldest female.  Herds are more likely to be found along the northern edge of the tropical rain system during the summer and move north as winter falls.  They are able to track rainfall and will head for these areas where vegetation is more plentiful. Males are territorial and guard females, while the females establish their own dominance hierarchies.Due to its slow movements, the addax is an easy target for predators such as humans, lions, leopards, cheetahs and African wild dogs. Caracals, servals and hyenas attack calves. The addax is normally not aggressive, though individuals may charge if they are disturbed.
+
+
+=== Adaptations ===
+
+The addax is amply suited to live in the deep desert under extreme conditions. It can survive without free water almost indefinitely, because it gets moisture from its food and dew that condenses on plants. Scientists believe the addax has a special lining in its stomach that stores water in pouches to use in times of dehydration. It also produces highly concentrated urine to conserve water. The pale colour of the coat reflects radiant heat, and the length and density of the coat helps in thermoregulation. In the day the addax huddles together in shaded areas, and on cool nights rests in sand hollows. These practices help in dissipation of body heat and saving water by cooling the body through evaporation.In a study, eight addaxes on a diet of grass hay (Chloris gayana) were studied to determine the retention time of food from the digestive tract. It was found that food retention time was long, taken as an adaptation to a diet including a high proportion of slow fermenting grasses; while the long fluid retention time could be interpreted to be due to water-saving mechanisms with low water turnover and a roomy rumen.
+
+
+=== Diet ===
+
+The addax lives in desert terrain where it eats grasses and leaves of what shrubs, leguminous herbs and bushes are available. Primarily a grazer, its staple foods include Aristida, Panicum, and Stipagrostis, and it will only consume browse, such as leaves of Acacia trees in the absence of these grasses. It also eats perennials which turn green and sprout at the slightest bit of humidity or rain. The addax eats only certain parts of the plant and tends to crop the Aristida grasses neatly to the same height. By contrast, when feeding on Panicum grass, the drier outer leaves are left alone while it eats the tender inner shoots and seeds. These seeds are important part of the addax's diet, being its main source of protein.
+
+
+=== Reproduction ===
+Females are sexually mature at 2 to 3 years of age and males at about 2 years. Breeding occurs throughout the year, but it peaks during winter and early spring. In the northern Sahara, breeding peaks at the end of winter and the beginning of spring; in the southern Sahara, breeding peaks from September to October and from January to mid-April. Each estrus bout lasts for one or two days.In a study, the blood serum of female addaxes was analyzed through immunoassay to know about their luteal phase. Estrous cycle duration was of about 33 days. During pregnancy, ultrasonography showed the uterine horns as coiled. The maximum diameters of the ovarian follicle and the corpus luteum were 15 mm (0.59 in) and 27 mm (1.1 in). Each female underwent an anovulatory period lasting 39 to 131 days, during which there was no ovulation. Anovulation was rare in winter, which suggested the effect of seasons on the estrous cycle.Gestation period lasts 257–270 days (about nine months). Females may lie or stand during the delivery, during which one calf is born. A postpartum estrus occurs after two or three days. The calf weighs 5 kg (11 lb) at birth and is weaned at 23–29 weeks old.
+
+
+== Habitat and distribution ==
+The addax inhabits arid regions, semideserts and sandy and stony deserts. It even occurs in extremely arid areas, with less than 100 mm annual rainfall. It also inhabits deserts with tussock grasses (Stipagrostis species) and succulent thorn scrub Cornulaca. Formerly, the addax was widespread in the Sahelo-Saharan region of Africa, west of the Nile Valley and all countries sharing the Sahara Desert; but today the only known self-sustaining population is present in the Termit Massif Reserve (Niger). However, there are reports of sightings from the eastern Air Mountains (Niger) and Bodélé (Chad). Rare nomads may be seen in northern Niger, southern Algeria and Libya; and the addax is rumoured to be present along the Mali/Mauritania border, though there have been no confirmed sightings. The addax was once abundant in North Africa, native to Chad, Mauritania and Niger. It is extinct in Algeria, Egypt, Libya, Sudan and the Western Sahara. It has been reintroduced into Morocco and Tunisia.
+
+
+== Threats and conservation ==
+
+Declines in the population of the addax have been ongoing since the mid-1800s. More recently, addaxes were found from Algeria to Sudan, but due mainly to overhunting, they have become much more restricted and rare.Addaxes are easy to hunt due to their slow movements. Roadkill, firearms for easy hunting and nomadic settlements near waterholes (their dry-season feeding places) have also decreased their numbers. Moreover, their meat and leather are highly prized. Other threats include chronic droughts in the deserts, habitat destruction due to more human settlements and agriculture. Fewer than 500 individuals are thought to exist in the wild today, most of the animals being found between the Termit area of Niger, the Bodélé region of western Chad, and the Aoukar in Mauritania.Today there are over 600 addaxes in Europe, Yotvata Hai-Bar Nature Reserve (Israel), Sabratha (Libya), Giza Zoo (Egypt), North America, Japan and Australia under captive breeding programmes. There are thousands more in private collections and ranches in the United States and the Middle East. Addaxes are legally protected in Morocco, Tunisia, and Algeria; hunting of all gazelles is forbidden in Libya and Egypt. Although enormous reserves, such as the Hoggar Mountains and Tasilli in Algeria, the Ténéré in Niger, the Ouadi Rimé-Ouadi Achim Faunal Reserve in Chad, and the newly established Wadi Howar National Park in Sudan, cover areas where the addax previously occurred, some do not keep addaxes at the present time because they lack the resources. The addax has been reintroduced into Bou-Hedma National Park (Tunisia) and Souss-Massa National Park (Morocco). Reintroductions in the wild are ongoing in Jebil National Park (Tunisia) and Grand Erg Oriental (the Sahara), and another is planned for Morocco.

+The impala or rooibok (Aepyceros melampus) is a medium-sized antelope found in eastern and southern Africa. The only extant member of the genus Aepyceros and tribe Aepycerotini, it was first described to European audiences by German zoologist Hinrich Lichtenstein in 1812. Two subspecies are recognised—the common impala, and the larger and darker black-faced impala. The impala reaches 70–92 cm (28–36 in) at the shoulder and weighs 40–76 kg (88–168 lb). It features a glossy, reddish brown coat. The male's slender, lyre-shaped horns are 45–92 cm (18–36 in) long.
+Active mainly during the day, the impala may be gregarious or territorial depending upon the climate and geography. Three distinct social groups can be observed: the territorial males, bachelor herds and female herds. The impala is known for two characteristic leaps that constitute an anti-predator strategy. Browsers as well as grazers, impala feed on monocots, dicots, forbs, fruits and acacia pods (whenever available). An annual, three-week-long rut takes place toward the end of the wet season, typically in May. Rutting males fight over dominance, and the victorious male courts female in oestrus. Gestation lasts six to seven months, following which a single calf is born and immediately concealed in cover. Calves are suckled for four to six months; young males—forced out of the all-female groups—join bachelor herds, while females may stay back.
+The impala is found in woodlands and sometimes on the interface (ecotone) between woodlands and savannahs; it inhabits places near water. While the black-faced impala is confined to southwestern Angola and Kaokoland in northwestern Namibia, the common impala is widespread across its range and has been reintroduced in Gabon and southern Africa. The International Union for Conservation of Nature (IUCN) classifies the impala as a species of least concern; the black-faced subspecies has been classified as a vulnerable species, with fewer than 1,000 individuals remaining in the wild as of 2008.
+
+
+== Etymology ==
+The first attested English name, in 1802, was palla or pallah, from the Tswana phala 'red antelope'; the name impala, also spelled impalla or mpala, is first attested in 1875. Its Afrikaans name, rooibok 'red buck', is also sometimes used in English.The scientific generic name Aepyceros (lit. ‘high-horned’) comes from Ancient Greek αἰπύς (aipus, 'high, steep') + κέρας (keras, 'horn'); the specific name melampus (lit. ‘black-foot’) from μελάς (melas, 'black') + πούς (pous, 'foot').
+
+
+== Taxonomy and evolution ==
+
+The impala is the sole member of the genus Aepyceros and belongs to the family Bovidae. It was first described by German zoologist Martin Hinrich Carl Lichtenstein in 1812. In 1984, palaeontologist Elisabeth Vrba opined that the impala is a sister taxon to the alcelaphines, given its resemblance to the hartebeest. A 1999 phylogenetic study by Alexandre Hassanin (of the National Centre for Scientific Research, Paris) and colleagues, based on mitochondrial and nuclear analyses, showed that the impala forms a clade with the suni (Neotragus moschatus). This clade is sister to another formed by the bay duiker (Cephalophus dorsalis) and the klipspringer (Oreotragus oreotragus). An rRNA and β-spectrin nuclear sequence analysis in 2003 also supported an association between Aepyceros and Neotragus. The following cladogram is based on the 1999 study:
+Up to six subspecies have been described, although only two are generally recognised on the basis of mitochondrial data. Though morphologically similar, the subspecies show a significant genetic distance between them, and no hybrids between them have been reported.
+A. m. melampus Lichtenstein, 1812: Known as the common impala, it occurs across eastern and southern Africa. The range extends from central Kenya to South Africa and westward into southeastern Angola.
+A. m. petersi Bocage, 1879: Known as the black-faced impala, it is restricted to southwestern Africa, occurring in northwestern Namibia and southwestern Angola.According to Vrba, the impala evolved from an alcelaphine ancestor. She noted that while this ancestor has diverged at least 18 times into various morphologically different forms, the impala has continued in its basic form for at least five million years. Several fossil species have been discovered, including A. datoadeni from the Pliocene of Ethiopia. The oldest fossil discovered suggests its ancient ancestors were slightly smaller than the modern form, but otherwise very similar in all aspects to the latter. This implies that the impala has efficiently adapted to its environment since prehistoric times. Its gregarious nature, variety in diet, positive population trend, defence against ticks and symbiotic relationship with the tick-feeding oxpeckers could have played a role in preventing major changes in morphology and behaviour.
+
+
+== Description ==
+
+The impala is a medium-sized, slender antelope similar to the kob or Grant's gazelle in build. The head-and-body length is around 130 centimetres (51 in). Males reach approximately 75–92 centimetres (30–36 in) at the shoulder, while females are 70–85 centimetres (28–33 in) tall. Males typically weigh 53–76 kilograms (117–168 lb) and females 40–53 kilograms (88–117 lb). Sexually dimorphic, females are hornless and smaller than males. Males grow slender, lyre-shaped horns 45–92 centimetres (18–36 in) long. The horns, strongly ridged and divergent, are circular in section and hollow at the base. Their arch-like structure allows interlocking of horns, which helps a male throw off his opponent during fights; horns also protect the skull from damage.The glossy coat of the impala shows two-tone colouration – the reddish brown back and the tan flanks; these are in sharp contrast to the white underbelly. Facial features include white rings around the eyes and a light chin and snout. The ears, 17 centimetres (6.7 in) long, are tipped with black. Black streaks run from the buttocks to the upper hindlegs. The bushy white tail, 30 centimetres (12 in) long, features a solid black stripe along the midline. The impala's colouration bears a strong resemblance to the gerenuk, which has shorter horns and lacks the black thigh stripes of the impala. The impala has scent glands covered by a black tuft of hair on the hindlegs. Sebaceous glands concentrated on the forehead and dispersed on the torso of dominant males are most active during the mating season, while those of females are only partially developed and do not undergo seasonal changes. There are four nipples.Of the subspecies, the black-faced impala is significantly larger and darker than the common impala; melanism is responsible for the black colouration. Distinctive of the black-faced impala is a dark stripe, on either side of the nose, that runs upward to the eyes and thins as it reaches the forehead. Other differences include the larger black tip on the ear, and a bushier and nearly 30% longer tail in the black-faced impala.The impala has a special dental arrangement on the front lower jaw similar to the toothcomb seen in strepsirrhine primates, which is used during allogrooming to comb the fur on the head and the neck and remove ectoparasites.
+
+
+== Ecology and behaviour ==
+
+The impala is diurnal (active mainly during the day), though activity tends to cease during the hot midday hours; they feed and rest at night. Three distinct social groups can be observed – the territorial males, bachelor herds and female herds. The territorial males hold territories where they may form harems of females; territories are demarcated with urine and faeces and defended against juvenile or male intruders. Bachelor herds tend to be small, with less than 30 members. Individuals maintain distances of 2.5–3 metres (8.2–9.8 ft) from one another; while young and old males may interact, middle-aged males generally avoid one another except to spar. Female herds vary in size from 6 to 100; herds occupy home ranges of 80–180 hectares (200–440 acres; 0.31–0.69 sq mi). The mother–calf bond is weak, and breaks soon after weaning; juveniles leave the herds of their mothers to join other herds. Female herds tend to be loose and have no obvious leadership. Allogrooming is an important means of social interaction in bachelor and female herds; in fact, the impala appears to be the only ungulate to display self-grooming as well as allogrooming. In allogrooming, females typically groom related impalas, while males associate with unrelated ones. Each partner grooms the other six to twelve times.
+
+Social behaviour is influenced by the climate and geography; as such, the impala are territorial at certain times of the year and gregarious at other times, and the length of these periods can vary broadly among populations. For instance, populations in southern Africa display territorial behaviour only during the few months of the rut, whereas in eastern African populations, territoriality is relatively minimal despite a protracted mating season. Moreover, territorial males often tolerate bachelors, and may even alternate between bachelorhood and territoriality at different times of the year. A study of impala in the Serengeti National Park showed that in 94% of the males, territoriality was observed for less than four months.The impala is an important prey species for several carnivores, such as cheetahs, leopards, wild dogs and lions. The antelope displays two characteristic leaps – it can jump up to 3 metres (9.8 ft), over vegetation and even other impala, covering distances of up to 10 metres (33 ft); the other type of leap involves a series of jumps in which the animal lands on its forelegs, moves its hindlegs mid-air in a kicking fashion, lands on all fours (stotting) and then rebounds. It leaps in either manner in different directions, probably to confuse predators. At times, the impala may also conceal itself in vegetation to escape the eye of the predator. The most prominent vocalisation is the loud roar, delivered through one to three loud snorts with the mouth closed, followed by two to ten deep grunts with the mouth open and the chin and tail raised; a typical roar can be heard up to 2 kilometres (1.2 mi) away. Scent gland secretions identify a territorial male. Impalas are sedentary; adult and middle-aged males, in particular, can hold their territories for years.
+
+
+=== Parasites ===
+
+Common ixodid ticks collected from impala include Amblyomma hebraeum, Boophilus decoloratus, Hyalomma marginatum, Ixodes cavipalpus, Rhipicephalus appendiculatus and R. evertsi. In Zimbabwe, heavy infestation by ticks such as R. appendiculatus has proved to be a major cause behind the high mortality of ungulates, as they can lead to tick paralysis. Impala have special adaptations for grooming, such as their characteristic dental arrangement, to manage ticks before they engorge; however, the extensive grooming needed to keep the tick load under control involves the risk of dehydration during summer, lower vigilance against predators and gradual wearing out of the teeth. A study showed that impala adjust the time devoted to grooming and the number of grooming bouts according to the seasonal prevalence of ticks.Impala are symbiotically related to oxpeckers, which feed on ticks from those parts of the antelope's body which the animal cannot access by itself (such as the ears, neck, eyelids, forehead and underbelly). The impala is the smallest ungulate with which oxpeckers are associated. In a study it was observed that oxpeckers selectively attended to impala despite the presence of other animals such as Coke's hartebeest, Grant's gazelle, Thomson's gazelle and topi. A possible explanation for this could be that because the impala inhabits woodlands (which can have a high density of ticks), the impala could have greater mass of ticks per unit area of the body surface. Another study showed that the oxpeckers prefer the ears over other parts of the body, probably because these parts show maximum tick infestation. The bird has also been observed to perch on the udders of a female and pilfer its milk.Lice recorded from impala include Damalinia aepycerus, D. elongata, Linognathus aepycerus and L. nevilli; in a study, ivermectin (a medication against parasites) was found to have an effect on Boophilus decoloratus and Linognathus species, though not on Damalinia species. In a study of impala in South Africa, the number of worms in juveniles showed an increase with age, reaching a peak when impala turned a year old. This study recorded worms of genera such as Cooperia, Cooperoides, Fasciola, Gongylonema. Haemonchus, Impalaia, Longistrongylus and Trichostrongylus; some of these showed seasonal variations in density.Impala show high frequency of defensive behaviours towards flying insects. This is probably the reason for Vale 1977 and Clausen et al 1998 only finding trace levels of feeding by Glossina (tsetse fly) upon impala.Theileria of impala in Kenya are not cross infectious to cattle: Grootenhuis et al 1975 were not able to induce cattle infection and Fawcett et al 1987 did not find it naturally occurring.
+
+
+=== Diet ===
+
+Impala browse as well as graze; either may predominate, depending upon the availability of resources. The diet comprises monocots, dicots, forbs, fruits and acacia pods (whenever available). Impala prefer places close to water sources, and resort to succulent vegetation if water is scarce. An analysis showed that the diet of impala is composed of 45% monocots, 45% dicots and 10% fruits; the proportion of grasses in the diet increases significantly (to as high as 90%) after the first rains, but declines in the dry season. Browsing predominates in the late wet and dry season, and diets are nutritionally poor in the mid-dry season, when impala feed mostly on woody dicots. Another study showed that the dicot proportion in the diet is much higher in bachelors and females than in territorial males.Impala feed on soft and nutritious grasses such as Digitaria macroblephara; tough, tall grasses, such as Heteropogon contortus and Themeda triandra, are typically avoided. Impala on the periphery of the herds are generally more vigilant against predators than those feeding in the centre; a foraging individual will try to defend the patch it is feeding on by lowering its head. A study revealed that time spent in foraging reaches a maximum of 75.5% of the day in the late dry season, decreases through the rainy season, and is minimal in the early dry season (57.8%).
+
+
+=== Reproduction ===
+
+Males are sexually mature by the time they are a year old, though successful mating generally occurs only after four years. Mature males start establishing territories and try to gain access to females. Females can conceive after they are a year and a half old; oestrus lasts for 24 to 48 hours, and occurs every 12–29 days in non-pregnant females. The annual three-week-long rut (breeding season) begins toward the end of the wet season, typically in May. Gonadal growth and hormone production in males begin a few months before the breeding season, resulting in greater aggressiveness and territoriality. The bulbourethral glands are heavier, testosterone levels are nearly twice as high in territorial males as in bachelors, and the neck of a territorial male tends to be thicker than that of a bachelor during the rut. Mating tends to take place between full moons.
+
+Rutting males fight over dominance, often giving out noisy roars and chasing one another; they walk stiffly and display their neck and horns. Males desist from feeding and allogrooming during the rut, probably to devote more time to garnering females in oestrus; the male checks the female's urine to ensure that she is in oestrus. On coming across such a female, the excited male begins the courtship by pursuing her, keeping a distance of 3–5 metres (9.8–16.4 ft) from her. The male flicks his tongue and may nod vigorously; the female allows him to lick her vulva, and holds her tail to one side. The male tries mounting the female, holding his head high and clasping her sides with his forelegs. Mounting attempts may be repeated every few seconds to every minute or two. The male loses interest in the female after the first copulation, though she is still active and can mate with other males.Gestation lasts six to seven months. Births generally occur in the midday; the female will isolate herself from the herd when labour pain begins. The perception that females can delay giving birth for an additional month if conditions are harsh may however not be realistic. A single calf is born, and is immediately concealed in cover for the first few weeks of its birth. The fawn then joins a nursery group within its mother's herd. Calves are suckled for four to six months; young males, forced out of the group, join bachelor herds, while females may stay back.
+
+
+== Distribution and habitat ==
+
+The impala inhabits woodlands due to its preference for shade; it can also be found on the interface (ecotone) between woodlands and savannahs. Places near water sources are preferred. In southern Africa, populations tend to be associated with Colophospermum mopane and Acacia woodlands. Habitat choices differ seasonally – Acacia senegal woodlands are preferred in the wet season, and A. drepanolobium savannahs in the dry season. Another factor that could influence habitat choice is vulnerability to predators; impala tend to keep away from areas with tall grasses as predators could be concealed there. A study found that the reduction of woodland cover and creation of shrublands by the African bush elephants has favoured impala population by increasing the availability of more dry season browse. Earlier, the Baikiaea woodland, which has now declined due to elephants, provided minimum browsing for impala. The newly formed Capparis shrubland, on the other hand, could be a key browsing habitat. Impala are generally not associated with montane habitats; however, in KwaZulu-Natal, impala have been recorded at altitudes of up to 1,400 metres (4,600 ft) above sea level.The historical range of the impala – spanning across southern and eastern Africa – has remained intact to a great extent, although it has disappeared from a few places, such as Burundi. The range extends from central and southern Kenya and northeastern Uganda in the east to northern KwaZulu-Natal in the south, and westward up to Namibia and southern Angola. The black-faced impala is confined to southwestern Angola and Kaokoland in northwestern Namibia; the status of this subspecies has not been monitored since the 2000s. The common impala has a wider distribution, and has been introduced in protected areas in Gabon and across southern Africa.
+
+
+== Threats and conservation ==
+
+The International Union for Conservation of Nature and Natural Resources (IUCN) classifies the impala as a species of least concern overall. The black-faced impala, however, is classified as a vulnerable species; as of 2008, fewer than 1,000 were estimated in the wild. Though there are no major threats to the survival of the common impala, poaching and natural calamities have significantly contributed to the decline of the black-faced impala. As of 2008, the population of the common impala has been estimated at around two million. According to some studies, translocation of the black-faced impala can be highly beneficial in its conservation.Around a quarter of the common impala populations occur in protected areas, such as the Okavango Delta (Botswana); Masai Mara and Kajiado (Kenya); Kruger National Park (South Africa); the Ruaha and Serengeti National Parks and Selous Game Reserve (Tanzania); Luangwa Valley (Zambia); Hwange, Sebungwe and Zambezi Valley (Zimbabwe). The rare black-faced impala has been introduced into private farms in Namibia and the Etosha National Park. Population densities vary largely from place to place; from less than one impala per square kilometre in Mkomazi National Park (Tanzania) to as high as 135 per square kilometre near Lake Kariba (Zimbabwe).

+The impala or rooibok (Aepyceros melampus) is a medium-sized antelope found in eastern and southern Africa. The only extant member of the genus Aepyceros and tribe Aepycerotini, it was first described to European audiences by German zoologist Hinrich Lichtenstein in 1812. Two subspecies are recognised—the common impala, and the larger and darker black-faced impala. The impala reaches 70–92 cm (28–36 in) at the shoulder and weighs 40–76 kg (88–168 lb). It features a glossy, reddish brown coat. The male's slender, lyre-shaped horns are 45–92 cm (18–36 in) long.
+Active mainly during the day, the impala may be gregarious or territorial depending upon the climate and geography. Three distinct social groups can be observed: the territorial males, bachelor herds and female herds. The impala is known for two characteristic leaps that constitute an anti-predator strategy. Browsers as well as grazers, impala feed on monocots, dicots, forbs, fruits and acacia pods (whenever available). An annual, three-week-long rut takes place toward the end of the wet season, typically in May. Rutting males fight over dominance, and the victorious male courts female in oestrus. Gestation lasts six to seven months, following which a single calf is born and immediately concealed in cover. Calves are suckled for four to six months; young males—forced out of the all-female groups—join bachelor herds, while females may stay back.
+The impala is found in woodlands and sometimes on the interface (ecotone) between woodlands and savannahs; it inhabits places near water. While the black-faced impala is confined to southwestern Angola and Kaokoland in northwestern Namibia, the common impala is widespread across its range and has been reintroduced in Gabon and southern Africa. The International Union for Conservation of Nature (IUCN) classifies the impala as a species of least concern; the black-faced subspecies has been classified as a vulnerable species, with fewer than 1,000 individuals remaining in the wild as of 2008.
+
+
+== Etymology ==
+The first attested English name, in 1802, was palla or pallah, from the Tswana phala 'red antelope'; the name impala, also spelled impalla or mpala, is first attested in 1875. Its Afrikaans name, rooibok 'red buck', is also sometimes used in English.The scientific generic name Aepyceros (lit. ‘high-horned’) comes from Ancient Greek αἰπύς (aipus, 'high, steep') + κέρας (keras, 'horn'); the specific name melampus (lit. ‘black-foot’) from μελάς (melas, 'black') + πούς (pous, 'foot').
+
+
+== Taxonomy and evolution ==
+
+The impala is the sole member of the genus Aepyceros and belongs to the family Bovidae. It was first described by German zoologist Martin Hinrich Carl Lichtenstein in 1812. In 1984, palaeontologist Elisabeth Vrba opined that the impala is a sister taxon to the alcelaphines, given its resemblance to the hartebeest. A 1999 phylogenetic study by Alexandre Hassanin (of the National Centre for Scientific Research, Paris) and colleagues, based on mitochondrial and nuclear analyses, showed that the impala forms a clade with the suni (Neotragus moschatus). This clade is sister to another formed by the bay duiker (Cephalophus dorsalis) and the klipspringer (Oreotragus oreotragus). An rRNA and β-spectrin nuclear sequence analysis in 2003 also supported an association between Aepyceros and Neotragus. The following cladogram is based on the 1999 study:
+Up to six subspecies have been described, although only two are generally recognised on the basis of mitochondrial data. Though morphologically similar, the subspecies show a significant genetic distance between them, and no hybrids between them have been reported.
+A. m. melampus Lichtenstein, 1812: Known as the common impala, it occurs across eastern and southern Africa. The range extends from central Kenya to South Africa and westward into southeastern Angola.
+A. m. petersi Bocage, 1879: Known as the black-faced impala, it is restricted to southwestern Africa, occurring in northwestern Namibia and southwestern Angola.According to Vrba, the impala evolved from an alcelaphine ancestor. She noted that while this ancestor has diverged at least 18 times into various morphologically different forms, the impala has continued in its basic form for at least five million years. Several fossil species have been discovered, including A. datoadeni from the Pliocene of Ethiopia. The oldest fossil discovered suggests its ancient ancestors were slightly smaller than the modern form, but otherwise very similar in all aspects to the latter. This implies that the impala has efficiently adapted to its environment since prehistoric times. Its gregarious nature, variety in diet, positive population trend, defence against ticks and symbiotic relationship with the tick-feeding oxpeckers could have played a role in preventing major changes in morphology and behaviour.
+
+
+== Description ==
+
+The impala is a medium-sized, slender antelope similar to the kob or Grant's gazelle in build. The head-and-body length is around 130 centimetres (51 in). Males reach approximately 75–92 centimetres (30–36 in) at the shoulder, while females are 70–85 centimetres (28–33 in) tall. Males typically weigh 53–76 kilograms (117–168 lb) and females 40–53 kilograms (88–117 lb). Sexually dimorphic, females are hornless and smaller than males. Males grow slender, lyre-shaped horns 45–92 centimetres (18–36 in) long. The horns, strongly ridged and divergent, are circular in section and hollow at the base. Their arch-like structure allows interlocking of horns, which helps a male throw off his opponent during fights; horns also protect the skull from damage.The glossy coat of the impala shows two-tone colouration – the reddish brown back and the tan flanks; these are in sharp contrast to the white underbelly. Facial features include white rings around the eyes and a light chin and snout. The ears, 17 centimetres (6.7 in) long, are tipped with black. Black streaks run from the buttocks to the upper hindlegs. The bushy white tail, 30 centimetres (12 in) long, features a solid black stripe along the midline. The impala's colouration bears a strong resemblance to the gerenuk, which has shorter horns and lacks the black thigh stripes of the impala. The impala has scent glands covered by a black tuft of hair on the hindlegs. Sebaceous glands concentrated on the forehead and dispersed on the torso of dominant males are most active during the mating season, while those of females are only partially developed and do not undergo seasonal changes. There are four nipples.Of the subspecies, the black-faced impala is significantly larger and darker than the common impala; melanism is responsible for the black colouration. Distinctive of the black-faced impala is a dark stripe, on either side of the nose, that runs upward to the eyes and thins as it reaches the forehead. Other differences include the larger black tip on the ear, and a bushier and nearly 30% longer tail in the black-faced impala.The impala has a special dental arrangement on the front lower jaw similar to the toothcomb seen in strepsirrhine primates, which is used during allogrooming to comb the fur on the head and the neck and remove ectoparasites.
+
+
+== Ecology and behaviour ==
+
+The impala is diurnal (active mainly during the day), though activity tends to cease during the hot midday hours; they feed and rest at night. Three distinct social groups can be observed – the territorial males, bachelor herds and female herds. The territorial males hold territories where they may form harems of females; territories are demarcated with urine and faeces and defended against juvenile or male intruders. Bachelor herds tend to be small, with less than 30 members. Individuals maintain distances of 2.5–3 metres (8.2–9.8 ft) from one another; while young and old males may interact, middle-aged males generally avoid one another except to spar. Female herds vary in size from 6 to 100; herds occupy home ranges of 80–180 hectares (200–440 acres; 0.31–0.69 sq mi). The mother–calf bond is weak, and breaks soon after weaning; juveniles leave the herds of their mothers to join other herds. Female herds tend to be loose and have no obvious leadership. Allogrooming is an important means of social interaction in bachelor and female herds; in fact, the impala appears to be the only ungulate to display self-grooming as well as allogrooming. In allogrooming, females typically groom related impalas, while males associate with unrelated ones. Each partner grooms the other six to twelve times.
+
+Social behaviour is influenced by the climate and geography; as such, the impala are territorial at certain times of the year and gregarious at other times, and the length of these periods can vary broadly among populations. For instance, populations in southern Africa display territorial behaviour only during the few months of the rut, whereas in eastern African populations, territoriality is relatively minimal despite a protracted mating season. Moreover, territorial males often tolerate bachelors, and may even alternate between bachelorhood and territoriality at different times of the year. A study of impala in the Serengeti National Park showed that in 94% of the males, territoriality was observed for less than four months.The impala is an important prey species for several carnivores, such as cheetahs, leopards, wild dogs and lions. The antelope displays two characteristic leaps – it can jump up to 3 metres (9.8 ft), over vegetation and even other impala, covering distances of up to 10 metres (33 ft); the other type of leap involves a series of jumps in which the animal lands on its forelegs, moves its hindlegs mid-air in a kicking fashion, lands on all fours (stotting) and then rebounds. It leaps in either manner in different directions, probably to confuse predators. At times, the impala may also conceal itself in vegetation to escape the eye of the predator. The most prominent vocalisation is the loud roar, delivered through one to three loud snorts with the mouth closed, followed by two to ten deep grunts with the mouth open and the chin and tail raised; a typical roar can be heard up to 2 kilometres (1.2 mi) away. Scent gland secretions identify a territorial male. Impalas are sedentary; adult and middle-aged males, in particular, can hold their territories for years.

+The rosy-faced lovebird (Agapornis roseicollis), also known as the rosy-collared or peach-faced lovebird, is a species of lovebird native to arid regions in southwestern Africa such as the Namib Desert. Loud and constant chirpers, these birds are very social animals and often congregate in small groups in the wild. They eat throughout the day and take frequent baths. Coloration can vary widely among populations. Plumage is identical in males and females. Lovebirds are renowned for their sleep position in which they sit side-by-side and turn their faces in towards each other. Also, females are well noted to tear raw materials into long strips, "twisty-tie" them onto their backs, and fly substantial distances back to make a nest. These birds are common in the pet industry.
+
+
+== Taxonomy ==
+It was described by the French ornithologist Louis Jean Pierre Vieillot in 1818. It was originally named Psittacus roseicollis but later moved to the genus Agapornis with the other lovebirds.
+Two subspecies are recognised:
+Agapornis roseicollis, (Vieillot, 1818)Agapornis roseicollis catumbella, B.P. Hall, 1952 - Angola
+Agapornis roseicollis roseicollis, (Vieillot 1818) - Namibia, Botswana, and South Africa
+
+
+== Description ==
+The rosy-faced lovebird is a fairly small bird, 17–18 cm long, with an average wing length of 106 mm and tail length of 44–52 mm. Wild birds are mostly green with a blue rump. The face and throat are pink, darkest on the forehead and above the eye. The bill is horn-coloured, the iris is brown, and the legs and feet are grey. The pink of the A. r. roseicollis is lighter than that of the A. r. catumbella. Juvenile birds have a pale pink face and throat, a greenish fore crown and crown, and the beak has a brownish base.
+
+
+== Distribution and habitat ==
+The rosy-faced lovebird inhabits dry, open country in southwest Africa. Its range extends from southwest Angola across most of Namibia to the lower Orange River valley in northwest South Africa. It lives up to 1,600 metres above sea level in broad-leaved woodland, semi-desert, and mountainous areas. It is dependent on the presence of water sources and gathers around pools to drink.
+Escapes from captivity are frequent in many parts of the world and feral birds dwell in metropolitan Phoenix, Arizona, where they live in a variety of habitats, both urban and rural. Some dwell in cacti and others have been known to frequent feeders in decent-sized flocks. Temperatures in Arizona regularly exceed 40°C and the feral lovebirds have been observed perching in large numbers on air-conditioner vents in order to remain cool. Although they have been observed in the wild in Puerto Rico, they are probably the result of escaped pets, and no reproduction has been recorded.
+
+
+=== Status and conservation ===
+Populations have been reduced in some areas by trapping for the pet trade. However, numbers may have increased in other areas due to human creation of new water sources and the building of artificial structures which provide new nesting sites. Because of this, the species is classed as Least Concern by the International Union for Conservation of Nature (IUCN).
+
+
+== Behaviour in the wild ==
+
+The rosy-faced lovebird has various harsh, shrieking calls.
+
+
+=== Feeding ===
+The diet consists mainly of seeds and berries. When food is plentiful, the birds may gather in flocks containing hundreds of individuals. They can sometimes be pests in agricultural areas, feeding on crops such as millet.
+
+
+=== Breeding ===
+
+Lovebirds are monomorphic, meaning the male and
+female of the species look alike. The nest is built in a rock crevice or within a compartment of the large communal nests built by sociable weavers. Man-made structures such as the roofs of houses may also be used. A total of 4-6 eggs are laid between February and April. They are dull white and measure 23.5 mm by 17.3 mm. They are incubated for about 23 days. The young birds fledge after 43 days.
+
+
+== Aviculture ==
+Rosy-faced lovebirds are one of the more common parrots kept in captivity, because of their small size and ease of care and breeding. The birds are kept alone or in pairs , although due to their social requirements, they are best kept in pairs. They can be aggressive, and tend to bond towards an individual, either human or avian, and may not get on well with other people or pets. Two lovebirds may not always get along, and may have to be separated, and lovebirds should not be kept with smaller species of birds. Lovebirds require daily exercise.

+
+=== Mutations ===
+
+Rosy-faced lovebirds have the widest range of colour mutations of all the Agapornis genus. Generally speaking, these mutations fall into the genetic categories of dominant, codominant, recessive, and sex-linked recessive. While this seems fairly straightforward, it can quickly become confusing when a single specimen has multiple examples of these mutational traits.

+The red panda (Ailurus fulgens), also known as the lesser panda, is a small mammal native to the eastern Himalayas and southwestern China. It has dense reddish-brown fur with a black belly and legs, white-lined ears, a mostly white muzzle and a ringed tail. Its head-to-body length is 51–63.5 cm (20.1–25.0 in) with a 28–48.5 cm (11.0–19.1 in) tail, and it weighs between 3.2 and 15 kg (7.1 and 33.1 lb). It is well adapted to climbing due to its flexible joints and curved semi-retractile claws.
+The red panda was first formally described in 1825. The two currently recognised subspecies, the Himalayan and the Chinese red panda, genetically diverged about 250,000 years ago. The red panda's place on the evolutionary tree has been debated, but modern genetic evidence places it in close affinity with raccoons, weasels, and skunks. It is not closely related to the giant panda, which is a bear, though both possess elongated wrist bones or "false thumbs" used for grasping bamboo. The evolutionary lineage of the red panda (Ailuridae) stretches back around 25 to 18 million years ago, as indicated by extinct fossil relatives found in Eurasia and North America.
+The red panda inhabits coniferous forests as well as temperate broadleaf and mixed forests, favouring steep slopes with dense bamboo cover close to water sources. It is solitary and largely arboreal. It feeds mainly on bamboo shoots and leaves, but also on fruits and blossoms. Red pandas mate in early spring, with the females giving birth to litters of up to four cubs in summer. It is threatened by poaching as well as destruction and fragmentation of habitat due to deforestation. The species has been listed as Endangered on the IUCN Red List since 2015. It is protected in all range countries.
+Community-based conservation programmes have been initiated in Nepal, Bhutan and northeastern India; in China, it benefits from nature conservation projects. Regional captive breeding programmes for the red panda have been established in zoos around the world. It is featured in animated movies, video games, comic books and as the namesake of companies and music bands.
+
+
+== Etymology ==
+The name "panda" is thought to have originated from the red panda's local Nepali name पञ्जा pajā "claw" or पौँजा paũjā "paw". In English, it was simply called "panda"; it became known as the "red panda" or "lesser panda" to distinguish it from the giant panda, which was formally described and named in 1869. The genus name Ailurus is adopted from the ancient Greek word αἴλουρος (ailouros), meaning "cat". The specific epithet fulgens is Latin for "shining, bright".
+
+
+== Taxonomy ==
+
+The red panda was described and named in 1825 by Frederic Cuvier, who gave it its current scientific name Ailurus fulgens. Cuvier's description was based on zoological specimens, including skin, paws, jawbones and teeth "from the mountains north of India", as well as an account by Alfred Duvaucel. The red panda was described earlier by Thomas Hardwicke in 1821, but his paper was only published in 1827. In 1902, Oldfield Thomas described a skull of a male red panda specimen under the name Ailurus fulgens styani in honour of Frederick William Styan who had collected this specimen in Sichuan.
+
+
+=== Subspecies and species ===
+The modern red panda is the only recognised species in the genus Ailurus. It is traditionally divided into two subspecies: the Himalayan red panda (A. f. fulgens) and the Chinese red panda (A. f. styani). The Himalayan subspecies has a straighter profile, a lighter coloured forehead and ochre-tipped hairs on the lower back and rump. The Chinese subspecies has a more curved forehead and sloping snout, a darker coat with a less white face and more contrast between the tail rings.In 2020, results of a genetic analysis of red panda samples showed that the red panda populations in the Himalayas and China were separated about 250,000 years ago. The researchers suggested that the two subspecies should be treated as distinct species. Red Pandas in southeastern Tibet and northern Myanmar were found to be part of styani, while those of southern Tibet were of fulgens in the strict sense. DNA sequencing of 132 red panda faecal samples collected in Northeast India and China also showed two distinct clusters indicating that the Siang River constitutes the boundary between the Himalayan and Chinese red pandas. They probably diverged due to glaciation events on the southern Tibetan Plateau in the Pleistocene.
+
+
+=== Phylogeny ===
+The placement of the red panda on the evolutionary tree has been debated. In the early 20th century, various scientists placed it in the family Procyonidae with raccoons and their allies. At the time, most prominent biologists also considered the red panda to be related to the giant panda, which would eventually be found to be a bear. A 1982 study examined the similarities and differences in the skull between the red panda and the giant panda, other bears and procyonids, and placed the species in its own family Ailuridae. The author of the study considered the red panda to be more closely related to bears. A 1995 mitochondrial DNA analysis revealed that the red panda has close affinities with procyonids. Further genetic studies in 2005, 2018 and 2021 have placed the red panda within the clade Musteloidea, which also includes Procyonidae, Mustelidae (weasels and relatives) and Mephitidae (skunks and relatives).
+
+
+=== Fossil record ===
+ 
+The family Ailuridae appears to have evolved in Europe in either the Late Oligocene or Early Miocene, about 25 to 18 million years ago. The earliest member Amphictis is known from its 10 cm (4 in) skull and may have been around the same size as the modern species. Its dentition consists of sharp premolars and carnassials (P4 and m1) and molars adapted for grinding (M1, M2 and m2), suggesting that it had a generalised carnivorous diet. Its placement within Ailuridae is based on the grooves on the side of its canine teeth. Other early or basal ailurids include Alopecocyon and Simocyon, whose fossils have been found throughout Eurasia and North America dating from the Middle Miocene, the latter of which survived into the Early Pliocene.  Both have similar teeth to Amphictis and thus had a similar diet. The puma-sized Simocyon was likely a tree-climber and shared a "false thumb"—an extended wrist bone—with the modern species, suggesting the appendage was an adaptation to arboreal locomotion and not to feed on bamboo.Later and more advanced ailurids are classified in the subfamily Ailurinae and are known as the "true" red pandas. These animals were smaller and more adapted for an omnivorous or herbivorous diet. The earliest known true panda is Magerictis from the Middle Miocene of Spain and known only from one tooth, a lower second molar. The tooth shows both ancestral and new characteristics having a relatively low and simple crown but also a lengthened crushing surface with developed tooth cusps like later species. Later ailurines include Pristinailurus bristoli which lived in eastern North America from the late Miocene to the Early Pliocene and species of the genus Parailurus which first appear in Early Pliocene Europe, spreading across Eurasia into North America. These animals are classified as a sister taxon to the lineage of the modern red panda. In contrast to the herbivorous modern species, these ancient pandas were likely omnivores, with highly cusped molars and sharp premolars.The earliest fossil record of the modern genus Ailurus date no earlier than the Pleistocene and appears to have been limited to Asia. The modern red panda's lineage became adapted for a specialised bamboo diet, having molar-like premolars and more elevated cusps. The false thumb would secondarily gain a function in feeding.
+
+
+=== Genomics ===
+Analysis of 53 red panda samples from Sichuan and Yunnan showed a high level of genetic diversity. The full genome of the red panda was sequenced in 2017. Researchers have compared it to the genome of the giant panda to learn the genetics of convergent evolution, as both species have false thumbs and are adapted for a specialised bamboo diet despite having the digestive system of a carnivore. Both pandas show modifications to certain limb development genes (DYNC2H1 and PCNT), which may play roles in the development of the thumbs. In switching from a carnivorous to a herbivorous diet, both species have reactivated taste receptor genes used for detecting bitterness, though the specific genes are different.
+
+
+== Description ==
+
+The red panda's coat is mainly red or orange-brown with a black belly and legs. The muzzle, cheeks, brows and inner ear margins are mostly white while the bushy tail has red and buff ring patterns and a dark brown tip. The colouration appears to serve as camouflage in habitat with red moss and white lichen-covered trees. The guard hairs are longer and rougher while the dense undercoat is fluffier with shorter hairs. The guard hairs on the back have a circular cross-section and are 47–56 mm (1.9–2.2 in) long. It has moderately long whiskers around the mouth, lower jaw and chin. The hair on the soles of the paws allows the animal to walk in snow.The red panda has a relatively small head, though proportionally larger than in similarly sized raccoons, with a reduced snout and triangular ears, and nearly evenly lengthed limbs. It has a head-body length of 51–63.5 cm (20.1–25.0 in) with a 28–48.5 cm (11.0–19.1 in) tail. The Himalayan red panda is recorded to weigh 3.2–9.4 kg (7.1–20.7 lb), while the Chinese red panda weighs 4–15 kg (8.8–33.1 lb) for females and 4.2–13.4 kg (9.3–29.5 lb) for males. It has five curved digits on each foot, each with curved semi-retractile claws that aid in climbing. The pelvis and hindlimbs have flexible joints, adaptations for an arboreal quadrupedal lifestyle. While not prehensile, the tail helps the animal balance while climbing.The forepaws possess a "false thumb", which is an extension of a wrist bone, the radial sesamoid found in many carnivorans. This thumb allows the animal grip onto bamboo stalks and both the digits and wrist bones are highly flexible. The red panda shares this feature with the giant panda, which has a larger sesamoid that is more compressed at the sides. In addition, the red panda's sesamoid has a more sunken tip while the giant panda's curves in the middle. These features give the giant panda more developed dexterity.The red panda's skull is wide, and its lower jaw is robust. However, because it eats leaves and stems, which are not as tough, it has smaller chewing muscles than the giant panda. The digestive system of the red panda is only 4.2 times its body length, with a simple stomach, no noticeable divide between the ileum and colon, and no caecum.
+
+
+== Distribution and habitat ==
+
+The red panda inhabits Nepal, the states of Sikkim, West Bengal and Arunachal Pradesh in India, Bhutan, southern Tibet, northern Myanmar and China's Sichuan and Yunnan provinces. The global potential habitat of the red panda has been estimated to comprise 47,100 km2 (18,200 sq mi) at most; this habitat is located in the temperate climate zone of the Himalayas with a mean annual temperature range of 18–24 °C (64–75 °F). Throughout this range, it has been recorded at elevations of 2,000–4,300 m (6,600–14,100 ft).
+In Nepal, it lives in six protected area complexes within the Eastern Himalayan broadleaf forests ecoregion. The westernmost records to date were obtained in three community forests in Kalikot District in 2019. Panchthar and Ilam Districts represent its easternmost range in the country, where its habitat in forest patches is surrounded by villages, livestock pastures and roads. The metapopulation in protected areas and wildlife corridors in the Kangchenjunga landscape of Sikkim and northern West Bengal is partly connected through old-growth forests outside protected areas. Forests in this landscape are dominated by Himalayan oaks (Quercus lamellosa and Q. semecarpifolia), Himalayan birch, Himalayan fir, Himalayan maple with bamboo, Rhododendron and some black juniper shrub growing in the understoreys. Records in Bhutan, Arunachal Pradesh's Pangchen Valley, West Kameng and Shi Yomi districts indicate that it frequents habitats with Yushania and Thamnocalamus bamboo, medium-sized Rhododendron, whitebeam and chinquapin trees. In China, it inhabits the Hengduan Mountains subalpine conifer forests and Qionglai-Minshan conifer forests in the Hengduan, Qionglai, Xiaoxiang, Daxiangling and Liangshan Mountains in Sichuan. In the adjacent Yunnan province, it was recorded only in the northwestern montane part.The red panda prefers microhabitats within 70–240 m (230–790 ft) of water sources. Fallen logs and tree stumps are important habitat features, as they facilitate access to bamboo leaves. Red pandas have been recorded to use steep slopes of more than 20° and stumps exceeding a diameter of 30 cm (12 in). Red pandas observed in Phrumsengla National Park used foremost easterly and southerly slopes with a mean slope of 34° and a canopy cover of 66 per cent that were overgrown with bamboo about 23 m (75 ft) in height. In Dafengding Nature Reserve, it prefers steep south-facing slopes in winter and inhabits forests with bamboo 1.5–2.5 m (4 ft 11 in – 8 ft 2 in) tall. In Gaoligongshan National Nature Reserve, it inhabits mixed coniferous forest with a dense canopy cover of more than 75 per cent, steep slopes and a density of at least 70 bamboo plants/m2 (6.5 bamboo plants/sq ft). In some parts of China, the red panda coexists with the giant panda. In Fengtongzhai and Yele National Nature Reserves, the red panda microhabitat is characterised by steep slopes with lots of bamboo stems, shrubs, fallen logs and stumps, whereas the giant panda prefers gentler slopes with taller but lesser amounts of bamboo and less habitat features overall. Such niche separation lessens competition between the two bamboo-eating species.
+
+
+== Behaviour and ecology ==
+
+The red panda is difficult to observe in the wild, and most studies on its behaviour have taken place in captivity. The red panda appears to be both nocturnal and crepuscular, sleeping in between periods of activity at night. It typically rests or sleeps in trees or other elevated spaces, stretched out prone on a branch with legs dangling when it is hot, and curled up with its hindlimb over the face when it is cold. It is adapted for climbing and descends to the ground head-first with the hindfeet holding on to the middle of the tree trunk. It moves quickly on the ground by trotting or bounding.
+
+
+=== Social spacing ===
+Adult pandas are generally solitary and territorial. Individuals mark their home range or territorial boundaries with urine, faeces and secretions from the anal and surrounding glands. Scent-marking is usually done on the ground, with males marking more often and for longer periods. In China's Wolong National Nature Reserve, the home range of a radio-collared female was 0.94 km2 (0.36 sq mi), while that of a male was 1.11 km2 (0.43 sq mi). A one-year-long monitoring study of ten red pandas in eastern Nepal showed that the four males had median home ranges of 1.73 km2 (0.67 sq mi) and the six females of 0.94 km2 (0.36 sq mi) within a forest cover of at least 19.2 ha (47 acres). The females travelled 419–841 m (1,375–2,759 ft) per day and the males 660–1,473 m (2,165–4,833 ft). In the mating season from January to March, adults travelled a mean of 795 m (2,608 ft) and subadults a mean of 861 m (2,825 ft). They all had larger home ranges in areas with low forest cover and reduced their activity in areas that were disturbed by people, livestock and dogs.
+
+
+=== Diet and feeding ===
+
+The red panda is largely herbivorous and feeds primarily on bamboo, mainly the genera Phyllostachys, Sinarundinaria, Thamnocalamus and Chimonobambusa. It also feeds on fruits, blossoms, acorns, eggs, birds and small mammals. Bamboo leaves may be the most abundant food item year-round and the only food they can access during winter. In Wolong National Nature Reserve, leaves of the bamboo species Bashania fangiana were found in nearly 94 per cent of analysed droppings, and its shoots were found in 59 per cent of the droppings found in June.The diet of red pandas monitored at three sites in Singalila National Park for two years consisted of 40–83 per cent Yushania maling and 51–91.2 per cent Thamnocalamus spathiflorus bamboos supplemented by bamboo shoots, Actinidia strigosa fruits and seasonal berries. In this national park, red panda droppings also contained remains of silky rose and bramble fruit species in the summer season, Actinidia callosa in the post-monsoon season, and Merrilliopanax alpinus, the whitebeam species Sorbus cuspidata and tree rhododendron in both seasons. Droppings were found on 23 plant species including the stone oak species Lithocarpus pachyphyllus, Campbell's magnolia, the chinquapin species Castanopsis tribuloides, Himalayan birch, Litsea sericea and the holly species Ilex fragilis. In Nepal's Rara National Park, Thamnocalamus was found in all the droppings sampled, both before and after the monsoon. Its summer diet in Dhorpatan Hunting Reserve also includes some lichens and barberries. In Bhutan's Jigme Dorji National Park, red panda faeces found in the fruiting season contained seeds of Himalayan ivy.The red panda grabs food with one of its front paws and usually eats sitting down or standing. When foraging for bamboo, it grabs the plant by the stem and pulls it down towards its jaws. It bites the leaves with the side of the cheek teeth and then shears, chews and shallows. Smaller food like blossoms, berries and small leaves are eaten differently, being clipped by the incisors. Having the gastrointestinal tract of a carnivore, the red panda cannot properly digest bamboo, which passes through its gut in two to four hours. Hence, it must consume large amounts of the most nutritious plant matter. It eats over 1.5 kg (3 lb 5 oz) of fresh leaves or 4 kg (9 lb) of fresh shoots in a day with crude proteins and fats being the most easily digested. Digestion is highest in summer and fall but lowest in winter, and is easier for shoots than leaves. The red panda's metabolic rate is comparable to other mammals of its size, despite its poor diet. The red panda digests almost a third of dry matter, which is more efficient than the giant panda digesting 17 per cent. Microbes in the gut may aid in its processing of bamboo; the microbiota community in the red panda is less diverse than in other mammals.
+
+
+=== Communication ===
+
+At least seven different vocalisations have been recorded from the red panda, comprising growls, barks, squeals, hoots, bleats, grunts and twitters. Growling, barking, grunting and squealing are produced during fights and aggressive chasing. Hooting is made in response to being approached by another individual. Bleating is associated with scent-marking and sniffing. Males may bleat during mating, while females twitter. During both play fighting and aggressive fighting, individuals curve their backs and tails while slowly moving their heads up and down. They then turn their heads while jaw-clapping, move their heads laterally and lift a forepaw to strike. They stand on their hind legs, raise the forelimbs above the head and then pounce. Two red pandas may "stare" at each other from a distance.
+
+
+=== Reproduction and parenting ===
+
+Red pandas are "long-day" breeders, reproducing after the winter solstice as daylight grows longer. Mating thus takes place from January to March, with births occurring from May to August. Reproduction is delayed by six months for captive pandas in the southern hemisphere. Oestrous lasts a day, and females can enter oestrous multiple times a season, but it is not known how long the intervals between each cycle last.As the reproductive season begins, males and females interact more, and will rest, move, and feed near each other. An oestrous female will spend more time marking and males will inspect her anogenital region. Receptive females make tail-flicks and position themselves in a lordosis pose, with the front lowered to the ground and the spine curved. Copulation involves the male mounting the female from behind and on top, though face-to-face matings as well as belly-to-back matings while lying on the sides also occur. The male will grab the female by the sides with his front paws instead of biting her neck. Intermission is 2–25 minutes long, and the couple grooms each other between each bout.Gestation lasts about 131 days. Prior to giving birth, the female selects a denning site, such as a tree, log or stump hollow or rock crevice, and builds a nest using material from nearby, such as twigs, sticks, branches, bark bits, leaves, grass and moss. Litters typically consist of one to four cubs that are born fully furred but blind. They are entirely dependent on their mother for the first three to four months until they first leave the nest. They nurse for their first five months. The bond between mother and offspring lasts until the next mating season. Cubs are fully grown at around 12 months and at around 18 months they reach sexual maturity. Two radio-collared cubs in eastern Nepal separated from their mothers at the age of 7–8 months and left their birth areas three weeks later. They reached new home ranges within 26–42 days and became residents after exploring them for 42–44 days.
+
+
+=== Mortality and diseases ===
+The red panda's lifespan in captivity reaches 14 years. They have been recorded falling prey to leopards in the wild. Faecal samples of red panda collected in Nepal contained parasitic protozoa, amoebozoans, roundworms, trematodes and tapeworms. Roundworms, tapeworms and coccidia were also found in red panda scat collected in Rara and Langtang National Parks. Fourteen red pandas at the Knoxville Zoo suffered from severe ringworm, so the tails of two were amputated. Chagas disease was reported as the cause of death of a red panda kept in a Kansas zoo. Amdoparvovirus was detected in the scat of six red pandas in the Sacramento Zoo. Eight captive red pandas in a Chinese zoo suffered from shortness of breath and fever shortly before they died of pneumonia; autopsy revealed that they had antibodies to the protozoans Toxoplasma gondii and Sarcocystis species indicating that they were intermediate hosts. A captive red panda in the Chengdu Research Base of Giant Panda Breeding died of unknown reasons; an autopsy showed that its kidneys, liver and lungs were damaged by a bacterial infection caused by Escherichia coli.
+
+
+== Threats ==
+The red panda is primarily threatened by the destruction and fragmentation of its habitat, the causes of which include increasing human population, deforestation, the unlawful taking of non-wood forest material and disturbances by herders and livestock. Trampling by livestock inhibits bamboo growth, and clearcutting decreases the ability of some bamboo species to regenerate. The cut lumber stock in Sichuan alone reached 2,661,000 m3 (94,000,000 cu ft) in 1958–1960, and around 3,597.9 km2 (1,389.2 sq mi) of red panda habitat were logged between the mid 1970s and late 1990s. Throughout Nepal, the red panda habitat outside protected areas is negatively affected by solid waste, livestock trails and herding stations, and people collecting firewood and medicinal plants. Threats identified in Nepal's Lamjung District include grazing by livestock during seasonal transhumance, human-made forest fires and the collection of bamboo as cattle fodder in winter. Vehicular traffic is a significant barrier to red panda movement between habitat patches.Poaching is also a major threat. In Nepal, 121 red panda skins were confiscated between 2008 and 2018. Traps meant for other wildlife have been recorded killing red pandas. In Myanmar, the red panda is threatened by hunting using guns and traps; since roads to the border with China were built starting in the early 2000s, red panda skins and live animals have been traded and smuggled across the border. In southwestern China, the red panda is hunted for its fur, especially for the highly valued bushy tails, from which hats are produced. The red panda population in China has been reported to have decreased by 40 per cent over the last 50 years, and the population in western Himalayan areas are considered to be smaller. Between 2005 and 2017, 35 live and seven dead red pandas were confiscated in Sichuan, and several traders were sentenced to 3–12 years of imprisonment. A month-long survey of 65 shops in nine Chinese counties in the spring of 2017 revealed only one in Yunnan offered hats made of red panda skins, and red panda tails were offered in an online forum.
+
+
+== Conservation ==
+The red panda is listed in CITES Appendix I and protected in all range countries; hunting is illegal. It has been listed as Endangered on the IUCN Red List since 2008 because the global population is estimated at 10,000 individuals, with a decreasing population trend. A large extent of its habitat is part of protected areas.
+

+=== In captivity ===
+
+The London Zoo received two red pandas in 1869 and 1876, the first of which was caught in Darjeeling. The Calcutta Zoo received a live red panda in 1877, the Philadelphia Zoo in 1906, and Artis and Cologne Zoos in 1908. In 1908, the first captive red panda cubs were born in an Indian zoo. In 1940, the San Diego Zoo imported four red pandas from India that had been caught in Nepal; their first litter was born in 1941. Cubs that were born later were sent to other zoos; by 1969, about 250 red pandas had been exhibited in zoos. The Taronga Conservation Society started keeping red pandas in 1977.In 1978, a breed registry, the International Red Panda Studbook, was set up, followed by the Red Panda European Endangered Species Programme in 1985. Members of international zoos ratified a global master plan for the captive breeding of the red panda in 1993. By late 2015, 219 red pandas lived in 42 zoos in Japan. The Padmaja Naidu Himalayan Zoological Park participates in the Red Panda Species Survival Plan and kept about 25 red pandas by 2016. By the end of 2019, 182 European zoos kept 407 red pandas. Regional captive breeding programmes have also been established in North American, Australasian and South African zoos.

+
+== Cultural significance ==
+
+The red panda's role in the culture and folklore of local people is limited. A drawing of a red panda exists on a 13th-century Chinese scroll. In Nepal's Taplejung District, red panda claws are used for treating epilepsy; its skin is used in rituals for treating sick people, making hats, scarecrows and decorating houses. In western Nepal, Magar shamans use its skin and fur in their ritual dresses and believe that it protects against evil spirits. People in central Bhutan consider red pandas to be reincarnations of Buddhist monks. Some tribal people in northeast India and the Yi people believe that it brings good luck to wear red panda tails or hats made of its fur. In China, the fur is used for local cultural ceremonies. At weddings, the bridegroom traditionally carries the hide. Hats made of red panda tails are also used by local newlyweds as a "good-luck charm".The red panda was recognised as the state animal of Sikkim in the early 1990s and was the mascot of the Darjeeling Tea Festival. It has been featured on stamps and coins issued by several red panda range states. Anthropomorphic red pandas feature in animated movies and TV series such as The White Snake Enchantress, Bamboo Bears, Barbie as the Island Princess, DreamWork's Kung Fu Panda franchise, Aggretsuko and Disney/Pixar's Turning Red, and in several video games and comic books. It is the namesake of the Firefox browser and has been used as the namesake of music bands and of companies. Its appearance has been used for plush toys, t-shirts, postcards and other items.

+The red panda (Ailurus fulgens), also known as the lesser panda, is a small mammal native to the eastern Himalayas and southwestern China. It has dense reddish-brown fur with a black belly and legs, white-lined ears, a mostly white muzzle and a ringed tail. Its head-to-body length is 51–63.5 cm (20.1–25.0 in) with a 28–48.5 cm (11.0–19.1 in) tail, and it weighs between 3.2 and 15 kg (7.1 and 33.1 lb). It is well adapted to climbing due to its flexible joints and curved semi-retractile claws.
+The red panda was first formally described in 1825. The two currently recognised subspecies, the Himalayan and the Chinese red panda, genetically diverged about 250,000 years ago. The red panda's place on the evolutionary tree has been debated, but modern genetic evidence places it in close affinity with raccoons, weasels, and skunks. It is not closely related to the giant panda, which is a bear, though both possess elongated wrist bones or "false thumbs" used for grasping bamboo. The evolutionary lineage of the red panda (Ailuridae) stretches back around 25 to 18 million years ago, as indicated by extinct fossil relatives found in Eurasia and North America.
+The red panda inhabits coniferous forests as well as temperate broadleaf and mixed forests, favouring steep slopes with dense bamboo cover close to water sources. It is solitary and largely arboreal. It feeds mainly on bamboo shoots and leaves, but also on fruits and blossoms. Red pandas mate in early spring, with the females giving birth to litters of up to four cubs in summer. It is threatened by poaching as well as destruction and fragmentation of habitat due to deforestation. The species has been listed as Endangered on the IUCN Red List since 2015. It is protected in all range countries.
+Community-based conservation programmes have been initiated in Nepal, Bhutan and northeastern India; in China, it benefits from nature conservation projects. Regional captive breeding programmes for the red panda have been established in zoos around the world. It is featured in animated movies, video games, comic books and as the namesake of companies and music bands.
+
+
+== Etymology ==
+The name "panda" is thought to have originated from the red panda's local Nepali name पञ्जा pajā "claw" or पौँजा paũjā "paw". In English, it was simply called "panda"; it became known as the "red panda" or "lesser panda" to distinguish it from the giant panda, which was formally described and named in 1869. The genus name Ailurus is adopted from the ancient Greek word αἴλουρος (ailouros), meaning "cat". The specific epithet fulgens is Latin for "shining, bright".
+
+
+== Taxonomy ==
+
+The red panda was described and named in 1825 by Frederic Cuvier, who gave it its current scientific name Ailurus fulgens. Cuvier's description was based on zoological specimens, including skin, paws, jawbones and teeth "from the mountains north of India", as well as an account by Alfred Duvaucel. The red panda was described earlier by Thomas Hardwicke in 1821, but his paper was only published in 1827. In 1902, Oldfield Thomas described a skull of a male red panda specimen under the name Ailurus fulgens styani in honour of Frederick William Styan who had collected this specimen in Sichuan.
+
+
+=== Subspecies and species ===
+The modern red panda is the only recognised species in the genus Ailurus. It is traditionally divided into two subspecies: the Himalayan red panda (A. f. fulgens) and the Chinese red panda (A. f. styani). The Himalayan subspecies has a straighter profile, a lighter coloured forehead and ochre-tipped hairs on the lower back and rump. The Chinese subspecies has a more curved forehead and sloping snout, a darker coat with a less white face and more contrast between the tail rings.In 2020, results of a genetic analysis of red panda samples showed that the red panda populations in the Himalayas and China were separated about 250,000 years ago. The researchers suggested that the two subspecies should be treated as distinct species. Red Pandas in southeastern Tibet and northern Myanmar were found to be part of styani, while those of southern Tibet were of fulgens in the strict sense. DNA sequencing of 132 red panda faecal samples collected in Northeast India and China also showed two distinct clusters indicating that the Siang River constitutes the boundary between the Himalayan and Chinese red pandas. They probably diverged due to glaciation events on the southern Tibetan Plateau in the Pleistocene.
+
+
+=== Phylogeny ===
+The placement of the red panda on the evolutionary tree has been debated. In the early 20th century, various scientists placed it in the family Procyonidae with raccoons and their allies. At the time, most prominent biologists also considered the red panda to be related to the giant panda, which would eventually be found to be a bear. A 1982 study examined the similarities and differences in the skull between the red panda and the giant panda, other bears and procyonids, and placed the species in its own family Ailuridae. The author of the study considered the red panda to be more closely related to bears. A 1995 mitochondrial DNA analysis revealed that the red panda has close affinities with procyonids. Further genetic studies in 2005, 2018 and 2021 have placed the red panda within the clade Musteloidea, which also includes Procyonidae, Mustelidae (weasels and relatives) and Mephitidae (skunks and relatives).
+
+
+=== Fossil record ===
+ 
+The family Ailuridae appears to have evolved in Europe in either the Late Oligocene or Early Miocene, about 25 to 18 million years ago. The earliest member Amphictis is known from its 10 cm (4 in) skull and may have been around the same size as the modern species. Its dentition consists of sharp premolars and carnassials (P4 and m1) and molars adapted for grinding (M1, M2 and m2), suggesting that it had a generalised carnivorous diet. Its placement within Ailuridae is based on the grooves on the side of its canine teeth. Other early or basal ailurids include Alopecocyon and Simocyon, whose fossils have been found throughout Eurasia and North America dating from the Middle Miocene, the latter of which survived into the Early Pliocene.  Both have similar teeth to Amphictis and thus had a similar diet. The puma-sized Simocyon was likely a tree-climber and shared a "false thumb"—an extended wrist bone—with the modern species, suggesting the appendage was an adaptation to arboreal locomotion and not to feed on bamboo.Later and more advanced ailurids are classified in the subfamily Ailurinae and are known as the "true" red pandas. These animals were smaller and more adapted for an omnivorous or herbivorous diet. The earliest known true panda is Magerictis from the Middle Miocene of Spain and known only from one tooth, a lower second molar. The tooth shows both ancestral and new characteristics having a relatively low and simple crown but also a lengthened crushing surface with developed tooth cusps like later species. Later ailurines include Pristinailurus bristoli which lived in eastern North America from the late Miocene to the Early Pliocene and species of the genus Parailurus which first appear in Early Pliocene Europe, spreading across Eurasia into North America. These animals are classified as a sister taxon to the lineage of the modern red panda. In contrast to the herbivorous modern species, these ancient pandas were likely omnivores, with highly cusped molars and sharp premolars.The earliest fossil record of the modern genus Ailurus date no earlier than the Pleistocene and appears to have been limited to Asia. The modern red panda's lineage became adapted for a specialised bamboo diet, having molar-like premolars and more elevated cusps. The false thumb would secondarily gain a function in feeding.
+
+
+=== Genomics ===
+Analysis of 53 red panda samples from Sichuan and Yunnan showed a high level of genetic diversity. The full genome of the red panda was sequenced in 2017. Researchers have compared it to the genome of the giant panda to learn the genetics of convergent evolution, as both species have false thumbs and are adapted for a specialised bamboo diet despite having the digestive system of a carnivore. Both pandas show modifications to certain limb development genes (DYNC2H1 and PCNT), which may play roles in the development of the thumbs. In switching from a carnivorous to a herbivorous diet, both species have reactivated taste receptor genes used for detecting bitterness, though the specific genes are different.
+
+
+== Description ==
+
+The red panda's coat is mainly red or orange-brown with a black belly and legs. The muzzle, cheeks, brows and inner ear margins are mostly white while the bushy tail has red and buff ring patterns and a dark brown tip. The colouration appears to serve as camouflage in habitat with red moss and white lichen-covered trees. The guard hairs are longer and rougher while the dense undercoat is fluffier with shorter hairs. The guard hairs on the back have a circular cross-section and are 47–56 mm (1.9–2.2 in) long. It has moderately long whiskers around the mouth, lower jaw and chin. The hair on the soles of the paws allows the animal to walk in snow.The red panda has a relatively small head, though proportionally larger than in similarly sized raccoons, with a reduced snout and triangular ears, and nearly evenly lengthed limbs. It has a head-body length of 51–63.5 cm (20.1–25.0 in) with a 28–48.5 cm (11.0–19.1 in) tail. The Himalayan red panda is recorded to weigh 3.2–9.4 kg (7.1–20.7 lb), while the Chinese red panda weighs 4–15 kg (8.8–33.1 lb) for females and 4.2–13.4 kg (9.3–29.5 lb) for males. It has five curved digits on each foot, each with curved semi-retractile claws that aid in climbing. The pelvis and hindlimbs have flexible joints, adaptations for an arboreal quadrupedal lifestyle. While not prehensile, the tail helps the animal balance while climbing.The forepaws possess a "false thumb", which is an extension of a wrist bone, the radial sesamoid found in many carnivorans. This thumb allows the animal grip onto bamboo stalks and both the digits and wrist bones are highly flexible. The red panda shares this feature with the giant panda, which has a larger sesamoid that is more compressed at the sides. In addition, the red panda's sesamoid has a more sunken tip while the giant panda's curves in the middle. These features give the giant panda more developed dexterity.The red panda's skull is wide, and its lower jaw is robust. However, because it eats leaves and stems, which are not as tough, it has smaller chewing muscles than the giant panda. The digestive system of the red panda is only 4.2 times its body length, with a simple stomach, no noticeable divide between the ileum and colon, and no caecum.
+
+
+== Distribution and habitat ==
+
+The red panda inhabits Nepal, the states of Sikkim, West Bengal and Arunachal Pradesh in India, Bhutan, southern Tibet, northern Myanmar and China's Sichuan and Yunnan provinces. The global potential habitat of the red panda has been estimated to comprise 47,100 km2 (18,200 sq mi) at most; this habitat is located in the temperate climate zone of the Himalayas with a mean annual temperature range of 18–24 °C (64–75 °F). Throughout this range, it has been recorded at elevations of 2,000–4,300 m (6,600–14,100 ft).
+In Nepal, it lives in six protected area complexes within the Eastern Himalayan broadleaf forests ecoregion. The westernmost records to date were obtained in three community forests in Kalikot District in 2019. Panchthar and Ilam Districts represent its easternmost range in the country, where its habitat in forest patches is surrounded by villages, livestock pastures and roads. The metapopulation in protected areas and wildlife corridors in the Kangchenjunga landscape of Sikkim and northern West Bengal is partly connected through old-growth forests outside protected areas. Forests in this landscape are dominated by Himalayan oaks (Quercus lamellosa and Q. semecarpifolia), Himalayan birch, Himalayan fir, Himalayan maple with bamboo, Rhododendron and some black juniper shrub growing in the understoreys. Records in Bhutan, Arunachal Pradesh's Pangchen Valley, West Kameng and Shi Yomi districts indicate that it frequents habitats with Yushania and Thamnocalamus bamboo, medium-sized Rhododendron, whitebeam and chinquapin trees. In China, it inhabits the Hengduan Mountains subalpine conifer forests and Qionglai-Minshan conifer forests in the Hengduan, Qionglai, Xiaoxiang, Daxiangling and Liangshan Mountains in Sichuan. In the adjacent Yunnan province, it was recorded only in the northwestern montane part.The red panda prefers microhabitats within 70–240 m (230–790 ft) of water sources. Fallen logs and tree stumps are important habitat features, as they facilitate access to bamboo leaves. Red pandas have been recorded to use steep slopes of more than 20° and stumps exceeding a diameter of 30 cm (12 in). Red pandas observed in Phrumsengla National Park used foremost easterly and southerly slopes with a mean slope of 34° and a canopy cover of 66 per cent that were overgrown with bamboo about 23 m (75 ft) in height. In Dafengding Nature Reserve, it prefers steep south-facing slopes in winter and inhabits forests with bamboo 1.5–2.5 m (4 ft 11 in – 8 ft 2 in) tall. In Gaoligongshan National Nature Reserve, it inhabits mixed coniferous forest with a dense canopy cover of more than 75 per cent, steep slopes and a density of at least 70 bamboo plants/m2 (6.5 bamboo plants/sq ft). In some parts of China, the red panda coexists with the giant panda. In Fengtongzhai and Yele National Nature Reserves, the red panda microhabitat is characterised by steep slopes with lots of bamboo stems, shrubs, fallen logs and stumps, whereas the giant panda prefers gentler slopes with taller but lesser amounts of bamboo and less habitat features overall. Such niche separation lessens competition between the two bamboo-eating species.
+
+
+== Behaviour and ecology ==
+
+The red panda is difficult to observe in the wild, and most studies on its behaviour have taken place in captivity. The red panda appears to be both nocturnal and crepuscular, sleeping in between periods of activity at night. It typically rests or sleeps in trees or other elevated spaces, stretched out prone on a branch with legs dangling when it is hot, and curled up with its hindlimb over the face when it is cold. It is adapted for climbing and descends to the ground head-first with the hindfeet holding on to the middle of the tree trunk. It moves quickly on the ground by trotting or bounding.
+
+
+=== Social spacing ===
+Adult pandas are generally solitary and territorial. Individuals mark their home range or territorial boundaries with urine, faeces and secretions from the anal and surrounding glands. Scent-marking is usually done on the ground, with males marking more often and for longer periods. In China's Wolong National Nature Reserve, the home range of a radio-collared female was 0.94 km2 (0.36 sq mi), while that of a male was 1.11 km2 (0.43 sq mi). A one-year-long monitoring study of ten red pandas in eastern Nepal showed that the four males had median home ranges of 1.73 km2 (0.67 sq mi) and the six females of 0.94 km2 (0.36 sq mi) within a forest cover of at least 19.2 ha (47 acres). The females travelled 419–841 m (1,375–2,759 ft) per day and the males 660–1,473 m (2,165–4,833 ft). In the mating season from January to March, adults travelled a mean of 795 m (2,608 ft) and subadults a mean of 861 m (2,825 ft). They all had larger home ranges in areas with low forest cover and reduced their activity in areas that were disturbed by people, livestock and dogs.
+
+
+=== Diet and feeding ===
+
+The red panda is largely herbivorous and feeds primarily on bamboo, mainly the genera Phyllostachys, Sinarundinaria, Thamnocalamus and Chimonobambusa. It also feeds on fruits, blossoms, acorns, eggs, birds and small mammals. Bamboo leaves may be the most abundant food item year-round and the only food they can access during winter. In Wolong National Nature Reserve, leaves of the bamboo species Bashania fangiana were found in nearly 94 per cent of analysed droppings, and its shoots were found in 59 per cent of the droppings found in June.The diet of red pandas monitored at three sites in Singalila National Park for two years consisted of 40–83 per cent Yushania maling and 51–91.2 per cent Thamnocalamus spathiflorus bamboos supplemented by bamboo shoots, Actinidia strigosa fruits and seasonal berries. In this national park, red panda droppings also contained remains of silky rose and bramble fruit species in the summer season, Actinidia callosa in the post-monsoon season, and Merrilliopanax alpinus, the whitebeam species Sorbus cuspidata and tree rhododendron in both seasons. Droppings were found on 23 plant species including the stone oak species Lithocarpus pachyphyllus, Campbell's magnolia, the chinquapin species Castanopsis tribuloides, Himalayan birch, Litsea sericea and the holly species Ilex fragilis. In Nepal's Rara National Park, Thamnocalamus was found in all the droppings sampled, both before and after the monsoon. Its summer diet in Dhorpatan Hunting Reserve also includes some lichens and barberries. In Bhutan's Jigme Dorji National Park, red panda faeces found in the fruiting season contained seeds of Himalayan ivy.The red panda grabs food with one of its front paws and usually eats sitting down or standing. When foraging for bamboo, it grabs the plant by the stem and pulls it down towards its jaws. It bites the leaves with the side of the cheek teeth and then shears, chews and shallows. Smaller food like blossoms, berries and small leaves are eaten differently, being clipped by the incisors. Having the gastrointestinal tract of a carnivore, the red panda cannot properly digest bamboo, which passes through its gut in two to four hours. Hence, it must consume large amounts of the most nutritious plant matter. It eats over 1.5 kg (3 lb 5 oz) of fresh leaves or 4 kg (9 lb) of fresh shoots in a day with crude proteins and fats being the most easily digested. Digestion is highest in summer and fall but lowest in winter, and is easier for shoots than leaves. The red panda's metabolic rate is comparable to other mammals of its size, despite its poor diet. The red panda digests almost a third of dry matter, which is more efficient than the giant panda digesting 17 per cent. Microbes in the gut may aid in its processing of bamboo; the microbiota community in the red panda is less diverse than in other mammals.
+
+
+=== Communication ===
+
+At least seven different vocalisations have been recorded from the red panda, comprising growls, barks, squeals, hoots, bleats, grunts and twitters. Growling, barking, grunting and squealing are produced during fights and aggressive chasing. Hooting is made in response to being approached by another individual. Bleating is associated with scent-marking and sniffing. Males may bleat during mating, while females twitter. During both play fighting and aggressive fighting, individuals curve their backs and tails while slowly moving their heads up and down. They then turn their heads while jaw-clapping, move their heads laterally and lift a forepaw to strike. They stand on their hind legs, raise the forelimbs above the head and then pounce. Two red pandas may "stare" at each other from a distance.
+
+
+=== Reproduction and parenting ===
+
+Red pandas are "long-day" breeders, reproducing after the winter solstice as daylight grows longer. Mating thus takes place from January to March, with births occurring from May to August. Reproduction is delayed by six months for captive pandas in the southern hemisphere. Oestrous lasts a day, and females can enter oestrous multiple times a season, but it is not known how long the intervals between each cycle last.As the reproductive season begins, males and females interact more, and will rest, move, and feed near each other. An oestrous female will spend more time marking and males will inspect her anogenital region. Receptive females make tail-flicks and position themselves in a lordosis pose, with the front lowered to the ground and the spine curved. Copulation involves the male mounting the female from behind and on top, though face-to-face matings as well as belly-to-back matings while lying on the sides also occur. The male will grab the female by the sides with his front paws instead of biting her neck. Intermission is 2–25 minutes long, and the couple grooms each other between each bout.Gestation lasts about 131 days. Prior to giving birth, the female selects a denning site, such as a tree, log or stump hollow or rock crevice, and builds a nest using material from nearby, such as twigs, sticks, branches, bark bits, leaves, grass and moss. Litters typically consist of one to four cubs that are born fully furred but blind. They are entirely dependent on their mother for the first three to four months until they first leave the nest. They nurse for their first five months. The bond between mother and offspring lasts until the next mating season. Cubs are fully grown at around 12 months and at around 18 months they reach sexual maturity. Two radio-collared cubs in eastern Nepal separated from their mothers at the age of 7–8 months and left their birth areas three weeks later. They reached new home ranges within 26–42 days and became residents after exploring them for 42–44 days.
+
+
+=== Mortality and diseases ===
+The red panda's lifespan in captivity reaches 14 years. They have been recorded falling prey to leopards in the wild. Faecal samples of red panda collected in Nepal contained parasitic protozoa, amoebozoans, roundworms, trematodes and tapeworms. Roundworms, tapeworms and coccidia were also found in red panda scat collected in Rara and Langtang National Parks. Fourteen red pandas at the Knoxville Zoo suffered from severe ringworm, so the tails of two were amputated. Chagas disease was reported as the cause of death of a red panda kept in a Kansas zoo. Amdoparvovirus was detected in the scat of six red pandas in the Sacramento Zoo. Eight captive red pandas in a Chinese zoo suffered from shortness of breath and fever shortly before they died of pneumonia; autopsy revealed that they had antibodies to the protozoans Toxoplasma gondii and Sarcocystis species indicating that they were intermediate hosts. A captive red panda in the Chengdu Research Base of Giant Panda Breeding died of unknown reasons; an autopsy showed that its kidneys, liver and lungs were damaged by a bacterial infection caused by Escherichia coli.
+
+
+== Threats ==
+The red panda is primarily threatened by the destruction and fragmentation of its habitat, the causes of which include increasing human population, deforestation, the unlawful taking of non-wood forest material and disturbances by herders and livestock. Trampling by livestock inhibits bamboo growth, and clearcutting decreases the ability of some bamboo species to regenerate. The cut lumber stock in Sichuan alone reached 2,661,000 m3 (94,000,000 cu ft) in 1958–1960, and around 3,597.9 km2 (1,389.2 sq mi) of red panda habitat were logged between the mid 1970s and late 1990s. Throughout Nepal, the red panda habitat outside protected areas is negatively affected by solid waste, livestock trails and herding stations, and people collecting firewood and medicinal plants. Threats identified in Nepal's Lamjung District include grazing by livestock during seasonal transhumance, human-made forest fires and the collection of bamboo as cattle fodder in winter. Vehicular traffic is a significant barrier to red panda movement between habitat patches.Poaching is also a major threat. In Nepal, 121 red panda skins were confiscated between 2008 and 2018. Traps meant for other wildlife have been recorded killing red pandas. In Myanmar, the red panda is threatened by hunting using guns and traps; since roads to the border with China were built starting in the early 2000s, red panda skins and live animals have been traded and smuggled across the border. In southwestern China, the red panda is hunted for its fur, especially for the highly valued bushy tails, from which hats are produced. The red panda population in China has been reported to have decreased by 40 per cent over the last 50 years, and the population in western Himalayan areas are considered to be smaller. Between 2005 and 2017, 35 live and seven dead red pandas were confiscated in Sichuan, and several traders were sentenced to 3–12 years of imprisonment. A month-long survey of 65 shops in nine Chinese counties in the spring of 2017 revealed only one in Yunnan offered hats made of red panda skins, and red panda tails were offered in an online forum.
+
+
+== Conservation ==
+The red panda is listed in CITES Appendix I and protected in all range countries; hunting is illegal. It has been listed as Endangered on the IUCN Red List since 2008 because the global population is estimated at 10,000 individuals, with a decreasing population trend. A large extent of its habitat is part of protected areas.
+
+A red panda anti-poaching unit and community-based monitoring have been established in Langtang National Park. Members of Community Forest User Groups also protect and monitor red panda habitats in other parts of Nepal. Community outreach programs have been initiated in eastern Nepal using information boards, radio broadcasting and the annual International Red Panda Day in September; several schools endorsed a red panda conservation manual as part of their curricula.Since 2010, community-based conservation programmes have been initiated in 10 districts in Nepal that aim to help villagers reduce their dependence on natural resources through improved herding and food processing practices and alternative income possibilities. The Nepali government ratified a five-year Red Panda Conservation Action Plan in 2019. From 2016 to 2019, 35 ha (86 acres) of high-elevation rangeland in Merak, Bhutan, was restored and fenced in cooperation with 120 herder families to protect the red panda forest habitat and improve communal land. Villagers in Arunachal Pradesh established two community conservation areas to protect the red panda habitat from disturbance and exploitation of forest resources. China has initiated several projects to protect its environment and wildlife, including Grain for Green, The Natural Forest Protection Project and the National Wildlife/Natural Reserve Construction Project. For the last project, the red panda is not listed as a key species for protection but may benefit from the protection of the giant panda and golden snub-nosed monkey, with which it overlaps in range.
+
+
+=== In captivity ===
+
+The London Zoo received two red pandas in 1869 and 1876, the first of which was caught in Darjeeling. The Calcutta Zoo received a live red panda in 1877, the Philadelphia Zoo in 1906, and Artis and Cologne Zoos in 1908. In 1908, the first captive red panda cubs were born in an Indian zoo. In 1940, the San Diego Zoo imported four red pandas from India that had been caught in Nepal; their first litter was born in 1941. Cubs that were born later were sent to other zoos; by 1969, about 250 red pandas had been exhibited in zoos. The Taronga Conservation Society started keeping red pandas in 1977.In 1978, a breed registry, the International Red Panda Studbook, was set up, followed by the Red Panda European Endangered Species Programme in 1985. Members of international zoos ratified a global master plan for the captive breeding of the red panda in 1993. By late 2015, 219 red pandas lived in 42 zoos in Japan. The Padmaja Naidu Himalayan Zoological Park participates in the Red Panda Species Survival Plan and kept about 25 red pandas by 2016. By the end of 2019, 182 European zoos kept 407 red pandas. Regional captive breeding programmes have also been established in North American, Australasian and South African zoos.

+== Cultural significance ==
+
+The red panda's role in the culture and folklore of local people is limited. A drawing of a red panda exists on a 13th-century Chinese scroll. In Nepal's Taplejung District, red panda claws are used for treating epilepsy; its skin is used in rituals for treating sick people, making hats, scarecrows and decorating houses. In western Nepal, Magar shamans use its skin and fur in their ritual dresses and believe that it protects against evil spirits. People in central Bhutan consider red pandas to be reincarnations of Buddhist monks. Some tribal people in northeast India and the Yi people believe that it brings good luck to wear red panda tails or hats made of its fur. In China, the fur is used for local cultural ceremonies. At weddings, the bridegroom traditionally carries the hide. Hats made of red panda tails are also used by local newlyweds as a "good-luck charm".The red panda was recognised as the state animal of Sikkim in the early 1990s and was the mascot of the Darjeeling Tea Festival. It has been featured on stamps and coins issued by several red panda range states. Anthropomorphic red pandas feature in animated movies and TV series such as The White Snake Enchantress, Bamboo Bears, Barbie as the Island Princess, DreamWork's Kung Fu Panda franchise, Aggretsuko and Disney/Pixar's Turning Red, and in several video games and comic books. It is the namesake of the Firefox browser and has been used as the namesake of music bands and of companies. Its appearance has been used for plush toys, t-shirts, postcards and other items.

+The mandarin duck (Aix galericulata) is a perching duck species native to the East Palearctic. It is medium-sized, at 41–49 cm (16–19 in) long with a 65–75 cm (26–30 in) wingspan. It is closely related to the North American wood duck, the only other member of the genus Aix. 'Aix' is an Ancient Greek word which was used by Aristotle to refer to an unknown diving bird, and 'galericulata' is the Latin for a wig, derived from galerum, a cap or bonnet. Outside of its native range, the mandarin duck has a large introduced population in the British Isles and Western Europe, with additional smaller introductions in North America.
+
+
+== Description ==
+The adult male has a red bill, large white crescent above the eye and reddish face and "whiskers". The male's breast is purple with two vertical white bars, the flanks ruddy, and he has two orange feathers at the back (large feathers that stick up similar to boat sails). The female is similar to the female wood duck, with a white eye-ring and stripe running back from the eye, but is paler below, has a small white flank stripe, and a pale tip to its bill.Both the males and females have crests, but the purple crest is more pronounced on the male.
+Like many other species of ducks, the male undergoes a moult after the mating season into eclipse plumage. When in eclipse plumage, the male looks similar to the female, but can be told apart by its bright yellow-orange or red beak, lack of any crest, and a less-pronounced eye-stripe.
+Mandarin ducklings are almost identical in appearance to wood ducklings, and very similar to mallard ducklings. The ducklings can be distinguished from mallard ducklings because the eye-stripe of mandarin ducklings (and wood ducklings) stops at the eye, while in mallard ducklings it reaches all the way to the bill.
+
+
+=== Mutations ===
+Various mutations of the mandarin duck are found in captivity. The most common is the white mandarin duck. Although the origin of this mutation is unknown, the constant pairing of related birds and selective breeding is presumed to have led to recessive gene combinations, leading in turn to genetic conditions including leucism.
+
+
+== Distribution and habitat ==
+The species was once widespread in East Asia, but large-scale exports and the destruction of its forest habitat have reduced populations in eastern Russia and in China to below 1,000 pairs in each country; Japan, however, is thought to still hold some 5,000 pairs. The Asian populations are migratory, overwintering in lowland eastern China and southern Japan.Specimens frequently escape from collections, and in the 20th century, a large, feral population was established in Great Britain; more recently, small numbers have bred in Ireland, concentrated in the parks of Dublin. Now, about 7,000 are in Britain with other populations on the European continent, the largest of which is in the region of Berlin. Isolated populations exist in the United States. The town of Black Mountain, North Carolina, has a limited population, and a free-flying feral population of several hundred mandarins exist in Sonoma County, California. This population is the result of several ducks escaping from captivity, then reproducing in the wild. In 2018, a single bird, dubbed Mandarin Patinkin, was seen in New York City's Central Park.The habitats it prefers in its breeding range are the dense, shrubby forested edges of rivers and lakes. It mostly occurs in low-lying areas, but it may breed in valleys at altitudes of up to 1,500 m (4,900 ft). In winter, it additionally occurs in marshes, flooded fields, and open rivers. While it prefers fresh water, it may also be seen wintering in coastal lagoons and estuaries. In its introduced European range, it lives in more open habitat than in its native range, around the edges of lakes, water meadows, and cultivated areas with woods nearby.
+
+
+== Behaviour ==
+Compared to other ducks, mandarins are shy birds, preferring to seek cover under trees such as overhanging willows, and form smaller flocks, but may become bolder as a result of becoming tame from frequent interaction with humans.
+
+
+=== Breeding ===
+
+In the wild, mandarin ducks breed in densely wooded areas near shallow lakes, marshes or ponds. They nest in cavities in trees close to water and during the spring. A single clutch of nine to twelve eggs is laid in April or May. Although the male may defend the brooding female and his eggs during incubation, he himself does not incubate the eggs and leaves before they hatch. Shortly after the ducklings hatch, their mother flies to the ground and coaxes the ducklings to leap from the nest. After all of the ducklings are out of the tree, they will follow their mother to a nearby body of water.
+
+
+=== Food and feeding ===
+
+Mandarins feed by dabbling or walking on land. They mainly eat plants and seeds, especially beech mast. The species will also add snails, insects and small fish to its diet. The diet of mandarin ducks changes seasonally; in the fall and winter, they mostly eat acorns and grains. In the spring, they mostly eat insects, snails, fish and aquatic plants. In the summer, they eat dew worms, small fish, frogs, mollusks, and small snakes. They feed mainly near dawn or dusk, perching in trees or on the ground during the day.
+
+
+== Threats ==
+Predation of the mandarin duck varies between different parts of its range. Mink, raccoon dogs, otters, polecats, Eurasian eagle-owls, and grass snakes are all predators of the mandarin duck. The greatest threat to the mandarin duck is habitat loss due to loggers. Hunters are also a threat to the mandarin duck, because often they are unable to recognize the mandarin in flight and as a result, many are shot by accident. Mandarin ducks are not hunted for food, but are still poached because their extreme beauty is prized.
+
+
+== In culture ==
+
+
+=== Chinese culture ===
+
+The Chinese refer to Mandarin ducks as yuanyang (simplified Chinese: 鸳鸯; traditional Chinese: 鴛鴦; pinyin: yuānyāng), where 'yuan' (鴛) and 'yang' (鴦) respectively stand for male and female mandarin ducks. In traditional Chinese culture, mandarin ducks are believed to be lifelong couples, unlike other species of ducks. Hence they are regarded as a symbol of conjugal affection and fidelity, and are frequently featured in Chinese art.
+A Chinese proverb for loving couples uses the mandarin duck as a metaphor: "Two mandarin ducks playing in water" (simplified Chinese: 鸳鸯戏水; traditional Chinese: 鴛鴦戲水; pinyin: yuānyāng xì shuǐ). A mandarin duck symbol is also used in Chinese weddings because in traditional Chinese lore, they symbolize wedded bliss and fidelity. Because the male and female plumages of the mandarin duck are so unalike, 'yuan-yang' is frequently used colloquially in Cantonese to mean an "odd couple" or "unlikely pair" – a mixture of two different types of same category. For example, the drink yuanyang and yuan-yang fried rice. Mandarin ducks featured on the flag of Weihaiwei during British rule.
+
+
+=== Korean culture ===
+
+For Koreans, mandarin ducks represent peace, fidelity, and plentiful offspring. Similar to the Chinese, they believe that these ducks mate for life. For these reasons, pairs of wooden-carved mandarin ducks called wedding ducks are often given as wedding gifts and play a significant role in Korean marriage.
+
+
+=== Japanese culture ===
+Similarly, in Japanese the ducks are called oshidori (おしどり/オシドリ/鴛鴦) and are used in the phrase oshidori fūfu (おしどり夫婦, "a couple of lovebirds/happily married couple").

+The American alligator (Alligator mississippiensis), sometimes referred to colloquially as a gator or common alligator, is a large crocodilian reptile native to the Southeastern United States. It is one of the two extant species in the genus Alligator, and is larger than the only other living alligator species, the Chinese alligator.
+Adult male American alligators measure 3.4 to 4.6 m (11.2 to 15.1 ft) in length, and can weigh up to 453 kg (999 lb), with unverified sizes of up to 5.85 m (19.2 ft) and weights of 1,000 kg (2,200 lb) making it one of the largest members of the family Alligatoridae, alongside the black caiman. Females are smaller, measuring 2.6 to 3 m (8.5 to 9.8 ft) in length. The American alligator inhabits subtropical and tropical freshwater wetlands, such as marshes and cypress swamps, from southern Texas to North Carolina. It is distinguished from the sympatric American crocodile by its broader snout, with overlapping jaws and darker coloration, and is less tolerant of saltwater but more tolerant of cooler climates than the American crocodile, which is found only in tropical and warm subtropical climates.
+American alligators are apex predators and consume fish, amphibians, reptiles, birds, and mammals. Hatchlings feed mostly on invertebrates. They play an important role as ecosystem engineers in wetland ecosystems through the creation of alligator holes, which provide both wet and dry habitats for other organisms. Throughout the year (in particular during the breeding season), American alligators bellow to declare territory, and locate suitable mates. Male American alligators use infrasound to attract females. Eggs are laid in a nest of vegetation, sticks, leaves, and mud in a sheltered spot in or near the water. Young are born with yellow bands around their bodies and are protected by their mother for up to one year.The conservation status of the American alligator is listed as Least Concern by the International Union for Conservation of Nature. Historically, hunting had decimated their population, and the American alligator was listed as an endangered species by the Endangered Species Act of 1973. Subsequent conservation efforts have allowed their numbers to increase and the species was removed from endangered status in 1987. The species is the official state reptile of three states: Florida, Louisiana, and Mississippi.
+
+
+== Taxonomy ==
+
+The American alligator was first classified by French zoologist François Marie Daudin as Crocodilus mississipiensis in 1801. In 1807, Georges Cuvier created the genus Alligator; the American alligator and the Chinese alligator are the only extant species in the genus. They are grouped in the family Alligatoridae with the caimans. The superfamily Alligatoroidea includes all crocodilians (fossil and extant) that are more closely related to the American alligator than to either the Nile crocodile (Crocodylus niloticus) or the gharial (Gavialis gangeticus).
+
+
+== Phylogeny ==
+
+Members of this superfamily first arose in the late Cretaceous, about 100–65 million years ago (Mya). Leidyosuchus of Alberta is the earliest known fossil, from the Campanian era 83 to 72 Mya.  Fossil alligatoroids have been found throughout Eurasia, because bridges across both the North Atlantic and the Bering Strait connected North America to Eurasia about 66 to 23 Mya.
+Alligators and caimans split in North America during the late Cretaceous, and the caimans reached South America by the Paleogene, before the closure of the Isthmus of Panama during the Neogene period, from about 23 to 2.58 Mya. The Chinese alligator likely descended from a lineage that crossed the Bering land bridge during the Neogene. Fossils identical to the existing American alligator are found throughout the Pleistocene, from 2.5 million to 11.7 thousand years ago. In 2016, a Miocene (about 23 to 5.3 Mya) fossil skull of an alligator was found at Marion County, Florida. Unlike the other extinct alligator species of the same genus, the fossil skull was virtually indistinguishable from that of the modern American alligator. This alligator and the American alligator are now considered to be sister taxa, meaning that the A. mississippiensis lineage has existed in North America for over 8 million years.The alligator's full mitochondrial genome was sequenced in the 1990s, and it suggests the animal evolved at a rate similar to mammals and greater than birds and most cold-blooded vertebrates. However, the full genome, published in 2014, suggests that the alligator evolved much more slowly than mammals and birds.
+
+
+== Characteristics ==
+
+Domestic American alligators range from long and slender to short and robust, possibly in response to variations in factors such as growth rate, diet, and climate.
+
+
+=== Size ===
+The American alligator is a relatively large species of crocodilian. On average, it is the largest species in the family Alligatoridae, with only the black caiman being possibly bigger. Weight varies considerably depending on length, age, health, season, and available food sources. Similar to many other reptiles that range expansively into temperate zones, American alligators from the northern end of their range, such as southern Arkansas, Alabama, and northern North Carolina, tend to reach smaller sizes. Large adult American alligators tend to be relatively robust and bulky compared to other similar-length crocodilians; for example, captive males measuring 3 to 4 m (9 ft 10 in to 13 ft 1 in) were found to weigh 200 to 350 kg (440 to 770 lb), although captive specimens may outweigh wild specimens due to lack of hunting behavior and other stressors.There is a common belief stated throughout reptilian literature that crocodilians including the American alligator exhibit indeterminate growth, meaning the animal continues to grow for the duration of its life. However, these claims are largely based on assumptions and observations of juvenile and young adult crocodilians. One long-term mark-recapture study (1979-2015) done at the Tom Yawkey Wildlife Center in South Carolina found evidence to support patterns of determinate growth. The study allowed for the observation of life histories noting some American alligators can possibly live over the age of seventy. This studies prolong documentation of growth rates, along with several other growing studies point toward the more newly supported pattern of determinant growth in the American alligator.
+
+
+==== Relation to age ====
+Large male American alligators reach an expected maximum size up to 4.6 m (15 ft 1 in) in length and weighing up to 453 kg (999 lb), while females reach a maximum of 3 m (9 ft 10 in). On rare occasions, a large, old male may grow to an even greater length.
+
+
+==== Largest ====
+During the 19th and 20th centuries, larger males reaching 5 to 6 m (16 ft 5 in to 19 ft 8 in) were reported. The largest reported individual size was a male killed in 1890 on Marsh Island, Louisiana, and reportedly measured at 5.84 m (19 ft 2 in) in length, but no voucher specimen was available, since the American alligator was left on a muddy bank after having been measured due to having been too massive to relocate. If the size of this animal was correct, it would have weighed about 1,000 kg (2,200 lb). In Arkansas, a man killed an American alligator that was 4.04 m (13 ft 3 in) and 626 kg (1,380 lb). The largest American alligator ever killed in Florida was 5.31 m (17 ft 5 in), as reported by the Everglades National Park. The largest American alligator scientifically verified in Florida for the period from 1977 to 1993 was reportedly 4.23 m (13 ft 11 in) and weighed 473 kg (1,043 lb), although another specimen (size estimated from skull) may have measured 4.54 m (14 ft 11 in). A specimen that was 4.8 m (15 ft 9 in) long and weighed 458.8 kg (1,011.5 lb) is the largest American alligator killed in Alabama and has been declared the SCI world record in 2014.
+
+
+==== Reported sizes ====
+
+
+==== Average ====
+American alligators do not normally reach such extreme sizes. In mature males, most specimens grow up to about 3.4 m (11 ft 2 in) in length, and weigh up to 360 kg (790 lb), while in females, the mature size is normally around 2.6 m (8 ft 6 in), with a body weight up to 91 kg (201 lb). In Newnans Lake, Florida, adult males averaged 73.2 kg (161 lb) in weight and 2.47 m (8 ft 1 in) in length, while adult females averaged 55.1 kg (121 lb) and measured 2.22 m (7 ft 3 in). In Lake Griffin State Park, Florida, adults weighed on average 57.9 kg (128 lb). Weight at sexual maturity per one study was stated as averaging 30 kg (66 lb) while adult weight was claimed as 160 kg (350 lb).
+
+
+==== Sexual dimorphism ====
+While noticeable in very mature specimens, the sexual dimorphism in size of the American alligator is relatively modest among crocodilians. In the saltwater crocodile, for example, the females are only slightly larger at average (2.4 m (7 ft 10 in) in the American alligator, 2.6 m (8 ft 6 in) in the saltwater crocodile) than female American alligators, but the mature males, at 4.3 to 5.2 m (14 ft 1 in to 17 ft 1 in) typically, as opposed to 2.4 to 4 m (7 ft 10 in to 13 ft 1 in) expected in mature male American alligators, are considerably bigger than male American alligators and at median are nearly twice as long as and at least four times as heavy as the female saltwater crocodiles of the same species. Given that female American alligators have relatively higher survival rates at an early age and a large percentage of given populations consists of immature or young breeding American alligators, relatively few large mature males of the expected mature length of 3.4 m (11 ft 2 in) or more are typically seen.
+
+
+=== Color ===
+Dorsally, adult American alligators may be olive, brown, gray, or black. However, they are on average one of the most darkly colored modern crocodilians (although other alligatorid family members are also fairly dark), and can be reliably be distinguished by color via their more blackish dorsal scales against crocodiles. Meanwhile, their undersides are cream-colored. Some American alligators are missing or have an inhibited gene for melanin, which makes them albino. These American alligators are extremely rare and almost impossible to find in the wild. They could only survive in captivity, as they are very vulnerable to the sun and predators.
+
+
+=== Jaws, teeth, and snout ===
+
+American alligators have 74-80 teeth. As they grow and develop, the morphology of their teeth and jaws change significantly. Juveniles have small, needle-like teeth that become much more robust and narrow snouts that become broader as the individuals develop. These morphological changes correspond to shifts in the American alligators' diets, from smaller prey items such as fish and insects to larger prey items such as turtles, birds, and other large vertebrates. American alligators have broad snouts, especially in captive individuals. When the jaws are closed, the edges of the upper jaws cover the lower teeth, which fit into the jaws' hollows. Like the spectacled caiman, this species has a bony nasal ridge, though it is less prominent. American alligators are often mistaken for a similar animal: the American crocodile. An easy characteristic to distinguish the two is the fourth tooth. Whenever an American alligator's mouth is closed, the fourth tooth is no longer visible. It is enclosed in a pocket in the upper jaw.
+
+
+=== Bite ===
+Adult American alligators held the record as having the strongest laboratory-measured bite of any living animal, measured at up to 13,172 N (1,343.2 kgf; 2,961 lbf). This experiment had not been, at the time of the paper published, replicated in any other crocodilians, and the same laboratory was able to measure a greater bite force of 16,414 N (1,673.8 kgf; 3,690 lbf) in saltwater crocodiles; notwithstanding this very high biting force, the muscles opening the American alligator's jaw are quite weak, and the jaws can be held closed by hand or tape when an American alligator is captured. No significant difference is noted between the bite forces of male and female American alligators of equal size. Another study noted that as the American alligator increases in size, the force of its bite also increases.
+
+
+=== Movement ===
+
+When on land, an American alligator moves either by sprawling or walking, the latter involving the reptile lifting its belly off the ground. The sprawling of American alligators and other crocodylians is not similar to that of salamanders and lizards, being similar to walking. Therefore, the two forms of land locomotion can be termed the "low walk" and the "high walk". Unlike most other land vertebrates, American alligators increase their speed through the distal rather than proximal ends of their limbs. In the water, American alligators swim like fish, moving their pelvic regions and tails from side to side. During respiration, air flow is unidirectional, looping through the lungs during inhalation and exhalation; the American alligator's abdominal muscles can alter the position of the lungs within the torso, thus shifting the center of buoyancy, which allows the American alligator to dive, rise, and roll within the water.
+
+
+== Distribution ==
+
+American alligators, being native both to the Nearctic and Neotropical realms, are found in the wild in the Southeastern United States, from the Lowcountry in South Carolina, south to Everglades National Park in Florida, and west to the southeastern region of Texas. They are found in parts of North Carolina, South Carolina, Georgia, Florida, Louisiana, Alabama, Mississippi, Arkansas, Oklahoma and Texas. Some of these locations appear to be relatively recent introductions, with often small but reproductive populations. Louisiana has the largest American alligator population of any U.S. state. In the future, possible American alligator populations may be found in areas of Mexico adjacent to the Texas border. Alligators have been naturally expanding their range into Tennessee, and have established a small population in the southwestern part of that state via inland waterways, according to the state's wildlife agency.
+
+
+== Conservation status ==
+
+American alligators are currently listed as least concern by the IUCN Red List, even though from the 1800s to the mid-1900s, they were being hunted and poached by humans unsustainably. In 1987, the U.S. Fish and Wildlife Service pronounced the American alligator fully recovered.Historically, hunting and habitat loss have severely affected American alligator populations throughout their range, and whether the species would survive was in doubt. In 1967, the American alligator was listed as an endangered species (under a law that was the precursor Endangered Species Act of 1973), since it was believed to be in danger of extinction throughout all or a significant portion of its range.Both the United States Fish and Wildlife Service (USFWS) and state wildlife agencies in the South contributed to the American alligator's recovery. Protection under the Endangered Species Act allowed the species to recuperate in many areas where it had been depleted. States began monitoring their American alligator populations to ensure that they would continue to grow. In 1987, the USFWS removed the animal from the endangered species list, as it was considered to be fully recovered. The USFWS still regulates the legal trade in American alligators and their products to protect still endangered crocodilians that may be passed off as American alligators during trafficking.American alligators are listed under Appendix II of the Convention on International Trade in Endangered Species (CITES) meaning that international trade in the species (including parts and derivatives) is regulated.
+
+
+== Habitat ==
+They inhabit swamps, streams, rivers, ponds, and lakes.  A lone American alligator was spotted for over 10 years living in a river north of Atlanta, Georgia. Females and juveniles are also found in Carolina Bays and other seasonal wetlands. While they prefer fresh water, American alligators may sometimes wander into brackish water, but are less tolerant of salt water than American crocodiles, as the salt glands on their tongues do not function. One study of American alligators in north-central Florida found the males preferred open lake water during the spring, while females used both swampy and open-water areas. During summer, males still preferred open water, while females remained in the swamps to construct their nests and lay their eggs. Both sexes may den underneath banks or clumps of trees during the winter.In some areas of their range, American alligators are an unusual example of urban wildlife; golf courses are often favoured by the species due to an abundance of water and a frequent supply of prey animals such as fish and birds.
+
+
+=== Cold tolerance ===
+American alligators are less vulnerable to cold than American crocodiles. Unlike an American crocodile, which would immediately succumb to the cold and drown in water at 45 °F (7 °C) or less, an American alligator can survive in such temperatures for some time without displaying any signs of discomfort. This adaptiveness is thought to be why American alligators are widespread further north than the American crocodile. In fact, the American alligator is found farther from the equator and is more equipped to handle cooler conditions than any other crocodilian. When the water begins to freeze, American alligators go into a period of brumation; they stick their snouts through the surface, which allows them to breathe above the ice, and they can remain in this state for several days.
+
+
+== Ecology and behavior ==
+
+
+=== Basking ===
+
+American alligators primarily bask on shore, but also climb into and perch on tree limbs to bask if no shoreline is available. This is not often seen, since if disturbed, they quickly retreat back into the water by jumping from their perch.
+
+
+=== Holes ===
+American alligators modify wetland habitats, most dramatically in flat areas such as the Everglades, by constructing small ponds known as alligator holes. This behavior has qualified the American alligator to be considered a keystone species. Alligator holes retain water during the dry season and provide a refuge for aquatic organisms, which survive the dry season by seeking refuge in alligator holes, so are a source of future populations. The construction of nests along the periphery of alligator holes, as well as a buildup of soils during the excavation process, provides drier areas for other reptiles to nest and a place for plants that are intolerant of inundation to colonize. Alligator holes are an oasis during the Everglades dry season, so are consequently important foraging sites for other organisms. In the limestone depressions of cypress swamps, alligator holes tend to be large and deep, while those in marl prairies and rocky glades are usually small and shallow, and those in peat depressions of ridge and slough wetlands are more variable. 
+
+
+=== Prey ===
+
+
+==== Bite and mastication ====
+The teeth of the American alligator are designed to grip prey, but cannot rip or chew flesh like teeth of some other predators (such as canids and felids), and depend on their gizzard, instead, to masticate their food. The American alligator is capable of biting through a turtle's shell or a moderately sized mammal bone.
+
+
+==== Tool use ====
+American alligators have been documented using lures to hunt prey such as birds. This means they are among the first reptiles recorded to use tools. By balancing sticks and branches on their heads, American alligators are able to lure birds looking for suitable nesting material to kill and consume. This strategy, which is shared by the mugger crocodile, is particularly effective during the nesting season, in which birds are more likely to gather appropriate nesting materials.
+
+
+==== Aquatic vs terrestrial ====
+
+Fish and other aquatic prey taken in the water or at the water's edge form the major part of American alligator's diet and may be eaten at any time of the day or night. Adult American alligators also spend considerable time hunting on land, up to 160 feet (50 m) from water, ambushing terrestrial animals on trailsides and road shoulders. Usually, terrestrial hunting occurs on nights with warm temperatures. When hunting terrestrial prey, American alligators may also ambush them from the edge of the water by grabbing them and pulling the prey into the water, the preferred method of predation of larger crocodiles.
+
+Additionally, American alligators have recently been filmed and documented killing and eating sharks and rays; four incidents documented indicated that bonnetheads, lemon sharks, Atlantic stingrays, and nurse sharks are components of the animal's diet. Sharks are also known to prey on American alligators, in turn, indicating that encounters between the two predators are common.
+
+
+==== Common ====
+American alligators are considered an apex predator throughout their range. They are opportunists and their diet is determined largely by both their size and age and the size and availability of prey. Most American alligators eat a wide variety of animals, including invertebrates, fish, birds, turtles, snakes, amphibians, and mammals. Hatchlings mostly feed on invertebrates such as insects, insect larvae, snails, spiders, and worms, as well as small fish and frogs. As they grow, American alligators gradually expand to larger prey. Once an American alligator reaches full size and power in adulthood, any animal living in the water or coming to the water to drink is potential prey. Most animals captured by American alligators are considerably smaller than itself. A few examples of animals consumed are largemouth bass, spotted gar, freshwater pearl mussels, American green tree frogs, yellow mud turtles, cottonmouths, common moorhens, and feral wild boars. Stomach contents show, among native mammals, muskrats and raccoons are some of the most commonly eaten species. In Louisiana, where introduced coypu are common, they are perhaps the most regular prey for adult American alligators, although only larger adults commonly eat this species. It has also been reported that large American alligators prey on medium-sized American alligators, which had preyed on hatchlings and smaller juveniles.If an American alligator's primary food resource is not available, it will sometimes feed on carrion and non-prey items such as rocks and artificial objects, like bottle caps. These items help the American alligator in the process of digestion by crushing up the meat and bones of animals, especially animals with shells.
+
+
+==== Large animals ====
+Other animals may occasionally be eaten, even large deer or feral wild boars, but these are not normally part of the diet. American alligators occasionally prey on large mammals, such as deer, but usually do so when fish and smaller prey levels go down. Rarely, American alligators have been observed killing and eating bobcats, but such events are not common and have little effect on bobcat populations. Although American alligators have been listed as predators of the Nilgai and the West Indian manatees, very little evidence exists of such predation. In the 2000s, when invasive Burmese pythons first occupied the Everglades, American alligators have been recorded preying on them, possibly controlling populations, thus preventing the invasive species from spreading northwards.
+American alligator predation on Florida panthers is rare, but has been documented. Such incidents usually involve a panther trying to cross a waterway or coming down to a swamp or river to get a drink. American alligator predation on American black bears has also been recorded.
+
+
+==== Domestic animals ====
+Occasionally, domestic animals, including dogs, cats, and calves, are taken as available, but are secondary to wild and feral prey. Other prey, including snakes, lizards, and various invertebrates, are eaten occasionally by adults.
+
+
+==== Birds ====
+Water birds, such as herons and egrets, storks, waterfowl and large dabbling rails such as gallinules or coots, are taken when possible. Occasionally, unwary adult birds are grabbed and eaten by American alligators, but most predation on bird species occurs with unsteady fledgling birds in late summer, as fledgling birds attempt to make their first flights near the water's edge.
+
+
+==== Fruit ====
+In 2013, American alligators and other crocodilians were reported to also eat fruit.
+Such behavior has been witnessed, as well as documented from stomach contents, with the American alligators eating such fruit as wild grapes, elderberries, and citrus fruits directly from the trees. The discovery of this unexpected part of the American alligator diet further reveals that they may be responsible for spreading seeds from the fruit they consume across their habitat. Additionally, American alligators engage in what seems to be cooperative hunting.
+
+
+==== In Florida and East Texas ====
+The diet of adult American alligators from central Florida lakes is dominated by fish, but the species is highly opportunistically based upon local availability. In Lake Griffin, fish made up 54% of the diet by weight, with catfish being most commonly consumed, while in Lake Apopka, fish made up 90% of the food and mostly shad were taken; in Lake Woodruff, the diet was 84% fish and largely consists of bass and sunfish. Unusually in these regions, reptiles and amphibians were the most important nonpiscivore prey, mostly turtles and water snakes. In southern Louisiana, crustaceans (largely crawfish and crabs) were found to be present in the southeastern American alligators, but largely absent in southwestern American alligators, which consumed a relatively high proportion of reptiles, although fish were the most recorded prey for adults, and adult males consumed a large portion of mammals.In East Texas, diets were diverse and adult American alligators took mammals, reptiles, amphibians, and invertebrates (e.g. snails) in often equal measure as they did fish.
+
+
+=== Vocalizations ===
+
+
+==== Mechanism ====
+An American alligator is able to abduct and adduct the vocal folds of its larynx, but not to elongate or shorten them; yet in spite of this, it can modulate fundamental frequency very well. Their vocal folds consists of epithelium, lamina propria and muscle. Sounds ranged from 50 to 1200 Hz. In one experiment conducted on the larynx, the fundamental frequency depended on both the glottal gap and stiffness of the larynx tissues. As the frequency increases, there's high tension and large strains. The fundamental frequency has been influenced by the glottal gap size and subglottal pressure and when the phonation threshold pressure has been exceeded, there will be vocal fold vibration.
+
+
+==== Calls ====
+Crocodilians are the most vocal of all non-avian reptiles and have a variety of different calls depending on the age, size, and sex of the animal. The American alligator can perform specific vocalizations to declare territory, signal distress, threaten competitors, and locate suitable mates. Juveniles can perform a high-pitched hatchling call (a "yelping" trait common to many crocodilian species' hatchling young) to alert their mothers when they are ready to emerge from the nest. Juveniles also make a distress call to alert their mothers if they are being threatened. Adult American alligators can growl, hiss, or cough to threaten others and declare territory.
+
+
+==== Bellowing ====
+Both males and females bellow loudly by sucking air into their lungs and blowing it out in intermittent, deep-toned roars to attract mates and declare territory. Males are known to use infrasound during mating bellows. Bellowing is performed in a "head oblique, tail arched" posture. Infrasonic waves from a bellowing male can cause the surface of the water directly over and to either side of his back to literally "sprinkle", in what is commonly called the "water dance". Large bellowing "choruses" of American alligators during the breeding season are commonly initiated by females and perpetuated by males. Observers of large bellowing choruses have noted they are often felt more than they are heard due to the intense infrasound emitted by males. American alligators bellow in B flat (specifically "B♭1", defined as an audio frequency of 58.27 Hz), and bellowing choruses can be induced by tuba players, sonic booms, and large aircraft.
+
+
+=== Reproduction ===
+
+
+==== Breeding season ====
+The breeding season begins in the spring. On spring nights, American alligators gather in large numbers for group courtship, in the aforementioned "water dances". The female builds a nest of vegetation, sticks, leaves, and mud in a sheltered spot in or near the water.
+
+
+==== Eggs ====
+After the female lays her 20 to 50 white eggs, about the size of a goose egg, she covers them with more vegetation, which heats as it decays, helping to keep the eggs warm. This differs from Nile crocodiles, which lay their eggs in pits. The temperature at which American alligator eggs develop determines their sex (see temperature-dependent sex determination). Studies have found that eggs hatched at a temperature below 88.7 °F or a temperature above 94.1 °F will produce female offspring, while those at a temperature between 90.5 °F to 92.3 °F will produce male offspring. The nests built on levees are warmer, thus produce males, while the cooler nests of wet marsh produce females. The female remains near the nest throughout the 65-day incubation period, protecting it from intruders. When the young begin to hatch — their "yelping" calls can sometimes even be heard just before hatching commences — the mother quickly digs them out and carries them to the water in her mouth, as some other crocodilian species are known to do.
+
+
+==== Young ====
+The young are tiny replicas of adults, with a series of yellow bands around their bodies that serve as camouflage. Hatchlings gather into pods and are guarded by their mother and keep in contact with her through their "yelping" vocalizations. Young American alligators eat small fish, frogs, crayfish, and insects. They are preyed on by large fish, birds, raccoons, Florida panthers, and adult American alligators. Mother American alligators eventually become more aggressive towards their young, which encourages them to disperse. Young alligators grow 3–8 in (7.6–20.3 cm) a year and reach adulthood at 6 ft (1.8 m).
+
+
+=== Interactions with exotic species ===
+Nutria were introduced into coastal marshes from South America in the mid-20th century, and their population has since exploded into the millions. They cause serious damage to coastal marshes and may dig burrows in levees. Hence, Louisiana has had a bounty to try to reduce nutria numbers. Large American alligators feed heavily on nutria, so American alligators may not only control nutria populations in Louisiana, but also prevent them spreading east into the Everglades. Since hunting and trapping preferentially take the large American alligators that are the most important in eating nutria, some changes in harvesting may be needed to capitalize on their ability to control nutria.Recently, a population of Burmese pythons became established in Everglades National Park. Substantial American alligator populations in the Everglades may be a contributing factor in keeping the python populations low, preventing the spread of the species north. While events of predation by Burmese pythons on young American alligators have been observed, no evidence of a net negative effect has been seen on overall American alligator populations.
+
+
+=== Indicators of environmental restoration ===
+
+American alligators play an important role in the restoration of the Everglades as biological indicators of restoration success. American alligators are highly sensitive to changes in the hydrology, salinity, and productivity of their ecosystems; all are factors that are expected to change with Everglades restoration. American alligators also may control the long-term vegetation dynamics in wetlands by reducing the population of small mammals, particularly coypu, which may otherwise overgraze marsh vegetation.  In this way, the vital ecological service they provide may be important in reducing rates of coastal wetland losses in Louisiana. They may provide a protection service for water birds nesting on islands in freshwater wetlands. American alligators prevent predatory mammals from reaching island-based rookeries and in return eat spilled food and birds that fall from their nests. Wading birds appear to be attracted to areas with American alligators and have been known to nest at heavily trafficked tourist attractions with large numbers of American alligators, such as the St. Augustine Alligator Farm in St. Augustine, Florida.
+
+
+== Relationship with humans ==
+
+
+=== Attacks on humans ===
+
+American alligators are capable of killing humans, but fatal attacks are fairly rare. Mistaken identity leading to an attack is always possible, especially in or near cloudy waters. American alligators are often less aggressive towards humans than larger crocodile species, a few of which (mainly the Nile and saltwater crocodiles) may prey on humans with some regularity. Alligator bites are serious injuries, due to the reptile's sheer bite force and risk of infection. Even with medical treatment, an American alligator bite may still result in a fatal infection.
+As human populations increase, and as they build houses in low-lying areas, or fish or hunt near water, incidents are inevitable where humans intrude on American alligators and their habitats. Since 1948, 257 documented attacks on humans in Florida (about five incidents per year) have been reported, of which an estimated 23 resulted in death. Only nine fatal attacks occurred in the United States throughout the 1970s–1990s, but American alligators killed 12 people between 2001 and 2007. An additional report of alligator attacks showed a total of 376 injuries and 15 deaths recorded all from 1948 to 2004, leading this to an increase of the alligator population. In May 2006, American alligators killed three Floridians in less than a week. At least 28 fatal attacks by American alligators have occurred in the United States since 1970.
+
+
+=== Wrestling ===
+
+Since the late 1880s, alligator wrestling has been a source of entertainment for some. Created by the Miccosukee and Seminole tribes prior to the arrival of Europeans, this tourism tradition continues to persist despite criticism from animal-rights activists.
+
+
+=== Farming ===
+
+Today, alligator farming is a large, growing industry in Georgia, Florida, Texas, and Louisiana. These states produce a combined annual total of some 45,000 alligator hides. Alligator hides bring good prices and hides in the 6- to 7-ft range have sold for $300 each. The market for alligator meat is growing, and about 300,000 pounds (140,000 kg) of meat are produced annually. According to the Florida Department of Agriculture and Consumer Services, raw alligator meat contains roughly 200 Calories (840 kJ) per 3-oz (85-g) portion, of which 27 Calories (130 kJ) come from fat.
+
+
+== Culture and film ==
+The American alligator is the official state reptile of Florida, Louisiana, and Mississippi. Several organizations and products from Florida have been named after the animal.
+"Gators" has been the nickname of the University of Florida's sports teams since 1911. In 1908, a printer made a spur-of-the-moment decision to print an alligator emblem on a shipment of the school's football pennants. The mascot stuck, and was made official in 1911, perhaps because the team captain's nickname was Gator. Allegheny College and San Francisco State University both have Gators as their mascots, as well.The Gator Bowl is a college football game held in Jacksonville annually since 1946, with Gator Bowl Stadium hosting the event until the 1993 edition. The Gatornationals is a NHRA drag race held at the Gainesville Raceway in Gainesville since 1970.

+The turquoise-fronted amazon (Amazona aestiva), also called the turquoise-fronted parrot, the blue-fronted amazon and the blue-fronted parrot, is a South American species of amazon parrot and one of the most common amazon parrots kept in captivity as a pet or companion parrot. Its common name is derived from the distinctive turquoise marking on its head just above its beak.
+
+
+== Taxonomy ==
+The turquoise-fronted amazon was one of the many species originally described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae. Its specific epithet is the feminine form of the Latin adjective aestivus, "of the summer". Two subspecies are recognized:
+A. a. aestiva (nominate) is found in eastern Brazil. The leading edge of the wing ("shoulder") is red.
+A. a. xanthopteryx occurs from northern and eastern Bolivia through adjacent parts of Brazil, to Paraguay and northern Argentina. The "shoulder" is partly or wholly yellow. Generally with more yellow to the head than nominate.The taxon xanthopteryx has been treated as a separate species, but the two subspecies interbreed freely where they come into contact.
+Additionally, there are significant individual variations in both facial pattern and amount of yellow/red to the "shoulder". In one extreme, individuals with essentially no yellow on the head and entirely green "shoulders" are known from north-western Argentina.
+
+
+== Description ==
+The turquoise-fronted amazon is a mainly green parrot about 38 cm (15 in) long. They have blue feathers on the forehead above the beak and yellow on the face and crown. Distribution of blue and yellow varies greatly among individuals. Unlike most other Amazona parrots, its beak is mostly black. There is no overt sexual dimorphism to the human eye, but analysis of the feathers using spectrometry, a method which allows the plumage to be seen as it would be by a parrot's tetrachromatic vision, shows clear differences between the plumage of the sexes. Juveniles of parrots are duller and have dark irises.
+
+
+== Distribution and habitat ==
+The range of the turquoise-fronted amazon extends over eastern and northern Bolivia, eastern Brazil, Paraguay and northern Argentina. It is found in forests (though generally avoids extensive humid forests such as the Amazon), woodland, savanna and palm groves.A small feral breeding population is also present in the greener regions of Stuttgart in Germany. Although they have been observed in the wild in Puerto Rico, they are probably the result of escaped pets, and no reproduction has been recorded.
+
+
+== Breeding ==
+The turquoise-fronted amazon nests in tree cavities. The oval eggs are white and measure around 38 × 30 mm. There are usually three to five in a clutch. The female incubates the eggs for about 27 days and the chicks leave the nest about 60 days after hatching.
+
+
+== Status ==
+The status of this species is evaluated as being of least concern by BirdLife International. However, while it remains common throughout a significant part of its range, there is evidence of a population decline, and this species has been heavily traded: Since 1981 when it was listed on CITES Appendix II, 413,505 wild-caught individuals have been recorded in international trade (UNEP-WCMC CITES Trade Database, January 2005). It is regarded as a crop pest in parts of its native range.
+Paradoxically, illegal trade may have contributed to expansions of the range of this parrot: It is becoming common in Rio de Janeiro, which is not a part of its historical range, something attributed to escaped caged birds.
+
+
+== Aviculture ==
+The turquoise-fronted amazon is commonly seen as a pet, both in South America and other parts of the world. Their talking ability varies greatly from individual to individual, but some speak nearly as well as the yellow-headed amazon group (yellow-naped, Panama, yellow-crowned, double yellow-headed. They seem to have a proclivity for singing. They require interaction but also can play with toys contently for several hours at a time. Pets require plenty of toys, perches, and climbing room. As with some other birds, under no circumstances are turquoise-fronted amazons to eat avocado. Some individuals, particularly males, can be aggressive in spring, the mating season.
+An extremely rare red (or chocolate raspberry) mutation of the species appeared in captivity in 2004, bred by the psittaculturist Howard Voren. The mutation results in yellow plumage being replaced by that of a red/pink hue and greens with a chocolate-brown, with the depth and intensity of color varying by location upon the body.

+The orange-winged amazon (Amazona amazonica), also known locally as orange-winged parrot and loro guaro, is a large  amazon parrot. It is a resident breeding bird in tropical South America, from Colombia, Trinidad and Tobago south to Peru, Bolivia and central Brazil. Its habitat is forest and semi-open country. Although common, it is persecuted as an agricultural pest and by capture for the pet trade (over 66,000 captured from 1981 to 1985). It is also hunted as a food source. Introduced breeding populations have been reported in Puerto Rico and Tenerife in the Canary Islands.
+
+
+== Taxonomy ==
+The orange-winged amazon was formally described in 1766 by the Swedish naturalist Carl Linnaeus in the twelfth edition of his Systema Naturae He placed it with all the other parrots in the genus Psittacus and coined the binomial name Psittacus amazonicus. Linnaeus cited the 1760 description by the French zoologist Mathurin Jacques Brisson. Brisson used the French name "Le Perroquet Amazone" and the Latin name later used by Linnaeus, Psittacus amazonicus. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. The orange-winged amazon is now one of around 30 species placed in the genus Amazona that was introduced by the French naturalist René Lesson in 1830. The species is considered to be monotypic: no subspecies are recognised.
+
+
+== Description ==
+The orange-winged amazon is a mainly green parrot about 33 cm (13 in) long and weighing about 340 g. It has blue and yellow feathers on its head which varies in extent between individuals. The upper mandible is partly horn colored (gray) and partly dark-gray. It has orange feathers in the wings and tail, which can be seen when in flight. The male and female are identical in external appearance.
+
+
+== Behavior ==
+
+
+=== Diet and feeding ===
+The orange-winged amazons are noisy birds and makes loud, high-pitched screams. It eats fruit, seeds, nuts, blossoms, leaf buds, and berries, including the fruit of palm trees and sometimes cocoa, mangoes, and oranges. It roosts communally in palm and other trees, and large numbers can be seen at the roost sites at dawn and dusk. It is becoming common as a feral bird in the Miami, Florida area, and there are colonies in London, England.
+
+
+=== Breeding ===
+
+The orange-winged amazon nests in tree cavities. The eggs are white and there are usually three or four in a clutch. The female incubates the eggs for about 26 days and the chicks leave the nest about 60 days after hatching.The orange-winged amazon has been introduced to Tenerife in the Canary Islands, where it has been observed successfully hybridizing with a feral scaly-headed parrot (Pionus maximiliani) and also attempting to breed with feral monk parakeet (Myiopsitta monachus) and rose-ringed parakeet (Psittacula krameri), even involving itself in the former species' unusual nest-building behaviour.

+The red-lored amazon or red-lored parrot (Amazona autumnalis) is a species of amazon parrot, native to tropical regions of the Americas, from eastern Mexico south to Ecuador where it occurs in humid evergreen to semi-deciduous forests up to 1,100 m altitude. It is absent from the Pacific side of Central America north of Costa Rica. Not originally known from El Salvador, a pair - perhaps escaped from captivity - nested successfully in 1995 and 1996 in the outskirts of San Salvador and the species might expand its range permanently into that country in the future. This species has also established feral populations in several California cities.
+
+
+== Taxonomy ==
+The red-lored amazon was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae. He placed it with all the other parrots in the genus Psittacus and coined the binomial name Psittacus autumnalis. Linnaeus based his description on the "lesser green parrot" that had been described and illustrated in 1751 by the English naturalist George Edwards in the fourth volume of his A Natural History of Uncommon Birds. Edwards mistakenly believed his specimen had come from the West Indies. The type locality was later designated as southern Mexico. The red-lored amazon is now one of around thirty species placed in the genus Amazona that was introduced by the French naturalist René Lesson in 1830. The genus name is a Latinized version of the name Amazone used in the 18th century by the Comte de Buffon. The specific epithet autumnalis is Latin for "autumnal".Three subspecies are recognised:
+A. a. autumnalis (Linnaeus, 1758) – east Mexico to north Nicaragua
+A. a. salvini (Salvadori, 1891) – north Nicaragua to southwest Colombia and northwest Venezuela
+A. a. lilacina (Lesson, R, 1844) – west Ecuador - the lilacine amazonThe lilacine amazon is considered by some authorities (such as BirdLife International) to be a distinct species, Amazona lilacina.The diademed amazon (Amazona diadema) is sometimes considered conspecific with this species.
+
+
+== Description ==
+The red-lored amazon is 32–35 centimetres (13–14 in) in length, with a weight of 310–480 g. The plumage is primarily green, with a red forehead and, in some subspecies, yellow cheeks (sometimes with red spots).  The crown is blue.  Adult males and females do not differ in plumage.  Juveniles have less yellow on the cheeks, less red on the forehead, and dark irises.
+
+
+== Behavior ==
+
+
+=== Food and feeding ===
+Their food includes fruits, nuts and seeds. Like all parrots, red-lored amazons need a varied diet consisting of high quality pellets, a quality seed mix, and daily servings of fresh, bird-safe fruits and vegetables.
+
+
+=== Breeding ===
+The red-lored amazon nests in tree cavities. The eggs are white and there are usually three or four in a clutch. The female incubates the eggs for about 26 days and the chicks leave the nest about 60 days after hatching.
+
+
+== Status ==
+In some areas, notably parts of Mexico and Venezuela, the red-lored amazon has become rare through trapping for the cagebird trade. On the other hand, it seems to be able to adapt to human-altered habitat to a considerable degree.
+
+
+== Aviculture ==
+Red-lored amazons are fairly common pet parrots in the Americas. They can be devoted pets and some make fairly good talkers. Like most amazon parrots they often have a tendency to vocalize loudly, and sometimes to bite. Their behavior ranges from being quiet and curious to being aggressive, this can all be changed by basic training when the bird is of a young age. Red-lored amazons can grow up to 13 inches in length. While they largely feast on seeds, fruits and nuts, avocados and eggplants are poisonous to them and can kill them. Their average life span is up to 80 years.

+The lilacine amazon (Amazona autumnalis lilacina) or Ecuadorian red-lored amazon is an amazon parrot native to Ecuador in South America. According to the IOC World Bird List, it is still considered to be a subspecies of the red-lored amazon, although Birdlife International considers it to be a separate species, as Amazona lilacina - as does the International Union for Conservation of Nature for the purposes of the IUCN Red List, rating the lilacine amazon as critically endangered.The lilacine amazon is generally smaller than its related subspecies, with a black beak and more subdued coloring. Lilacine amazons are said to make favorable companion parrots because of their gentle, affectionate nature and agreeable temperament.
+
+
+== Description ==
+The lilacine amazon is a small parrot, approximately 34 cm long when mature, with primarily green plumage. Like the red-lored amazon, it has red lores and yellow cheeks; its distinguishing features include a fully black beak, and lilac-tipped feathers on its crown.
+
+
+== Behavior ==
+The lilacine amazon is known for its gentle and timid nature. In the wild it avoids confrontation with intruders, opting to seek cover in nearby foliage until danger has passed. It usually spends time in small- to medium-sized groups, with which it roosts at night; many birds pair off monogamously within the larger group, and they are most frequently seen flying in pairs.
+
+
+=== Diet ===
+The diet of the lilacine amazon consists primarily of fruits, nuts, berries, and seeds. Like most parrots, it possesses a powerful beak; its dexterous tongue also helps to break down and consume a diverse suite of foodstuffs.
+
+
+=== Breeding ===
+Sexual maturity is reached at three or four years of age. Like most parrots, the lilacine amazon is a monogamous breeder and a cavity nester. The hen will lay two to four eggs in a tree cavity and incubate them for a period of three weeks; the young fledge about two months after hatching.As with many other parrots, the male will keep the female and chicks nourished during their time in the nest by consuming additional food and regurgitating it for them.
+
+
+== Distribution and habitat ==
+The lilacine amazon is native to the tropical dry forests of western Ecuador north of the Gulf of Guayaquil, extending to Nariño in extreme south-western Colombia adjacent to the Ecuadorian border, where it intersects with the subspecies A. a. salvini.
+
+
+== Aviculture ==
+Lilacine amazons have become well regarded as companion parrots, intelligent with a personality often described as gentle, affectionate, and loyal. In captivity, they enjoy the company of people, and will often form a strong bond with their owner. They are not known as exceptional talkers, but most individuals are able to learn to mimic at least a few phrases. The World Parrot Trust recommends that the lilacine amazon be housed in an enclosure with a minimum length of 3 metres.The lilacine amazon has only recently become popular and common in the pet trade, formerly being quite rare. At least one captive breeding program has been established in Europe to increase the bird's numbers.

+The red-browed amazon (Amazona rhodocorytha) is a species of parrot in the family Psittacidae. It is endemic to Atlantic Forest in eastern Brazil. It has been considered a subspecies of the blue-cheeked amazon (Amazona dufresniana), but today all major authorities consider them separate species. It is threatened both by habitat loss and by being captured for the trade in wild parrots.
+
+
+== Description ==
+The red-browed amazon has a bright red crown fading to purplish-brown at the back. The cheeks and throat are blue and the wing and body plumage is green with dark markings on the back of the neck. Black and red patches can be seen on the wings when they are spread and the tail feathers have red markings and are tipped with yellow. The beak and legs are grey and the iris of the eye is orange-brown.
+
+
+== Distribution and habitat ==
+The red-browed amazon is endemic to tropical forests in eastern Brazil. It used to be widespread across the region but is now restricted to some of the larger remaining forest blocks. The largest of these is in the state of Espírito Santo and the bird is also present in three forest areas in south east Bahia and five in the states of Rio de Janeiro and Minas Gerais. Another location is in the north of the state of São Paulo and a further one in São Miguel dos Campos in the east of the state of Alagoas. The rest of this state seems to be suitable habitat but it has not been observed to be present there recently.
+
+
+== Behaviour ==
+The red-browed amazon feeds in small groups on fruit, berries, seeds and buds which it finds in the rainforest canopy. Breeding takes place between September and November. A pair of red-browed amazons maintain a territory and the nest is usually made in a cavity in a tree, the same site being used year after year. In captivity, a clutch of four eggs are usually laid, incubation takes 24 days and the young are fledged 34 days after hatching.
+
+
+== Status ==
+The red-browed amazon used to be abundant in its rainforest habitat but its numbers appear to have decreased significantly. About 2,300 individuals were counted in Espírito Santo during a survey undertaken between 2004 and 2006 and it remains common at a few sites in the state such as on the island of Ilha Grande, at Sooretama and nearby Linhares. The major threat faced by this parrot is habitat degradation with less than ten percent of the original forest cover remaining in Espírito Santo. Most of the land has been cleared of timber and converted to pasture and plantations. Another threat is the illegal collection of young birds for the international pet trade. This bird is present in several wildlife reserves but is not effectively protected against poaching even there. For all these reasons, the IUCN, in its Red List of Endangered Species, has assessed the Red-browed amazon as "Vulnerable".

+The red-crowned amazon (Amazona viridigenalis), also known as the red-crowned parrot, green-cheeked amazon or Mexican red-headed parrot, is an endangered amazon parrot native to northeastern Mexico and possibly southern Texas in the United States. A 1994 study estimated wild populations of between 2,000 and 4,300 mature individuals; the IUCN Red List considers it a globally endangered species with a decreasing population. The main threats to the native bird's survival are the illegal export of trapped birds from Mexico to the United States for the pet trade and the destruction of their natural habitat, the lowland forests of northeastern Mexico.
+
+
+== Description ==
+
+Their appearance is generally green with the most notable features being a bright red forehead and crown, dark blue streak behind the eyes, and light green cheeks. It is not uncommon for red-crowned amazons to have splashes of red and blue under their wings and have light yellow-tipped tails. They have a white eye-ring which brings out their eyes. Their iris color can range from a bright yellow to a deep red, although juveniles' eyes are gray until maturity. Red-crowned amazons usually have horn colored beaks and ceres but these can sometimes have black highlights. Their legs are flesh-colored or gray. They are approximately 11-13 inches in length from the beak to the tip of the tail feathers with a wingspan of 15-16 inches. Amazon parrots are not sexually dimorphic, so the only true way to know a parrot's sex is by genetic testing. Their average weight is 270g.
+
+
+== Range ==
+Their natural range is across the lowlands of northeastern Mexico, and possibly the southern tip of Texas. Red-crowned amazons are a resident (non-migratory) species in their native range, but they can wander outside of their breeding range to follow a food source. Feral birds have bred in urban communities of southern California, southern Florida and the island of Oahu in Hawaii.
+On June 4th, 2019, the Corpus Christi Ecological Services Field Office of the US Fish & Wildlife Service announced to the public that the USFWS considers the red-crowned parrot native to Texas in the Rio Grande Valley. However, because parrots were not mentioned in the Migratory Bird Treaty Act of 1918, birds in the Texas portion of their range are not entitled to USFWS protection, and must rely on enacted state and local laws. It is considered an Imperiled species (S2) in Texas. The USFWS estimated that there are roughly 700 wild red-crowned parrots in the Rio Grande Valley of Texas in 2019, and historical records place parrots in South Texas as early as 1885. The numbers of wild parrots in the United States now rivals populations in Mexico, due to their adaptation to urban life. However, the IUCN and other resources consider the bird to be non-native to all parts of the United States, including southern Texas. NatureServe considers the species to be "Imperiled".
+
+
+=== Feral parrots ===
+Populations of feral parrots exist in cities such as the Los Angeles metropolitan area in California, USA, especially the San Gabriel Valley. Populations also exist in the San Diego area. Captured birds there escaped and became part of the urban ecosystem, starting in about the 1960s. The California Parrot Project says that red-crowned amazons are among the thirteen species of parrots with naturalized populations in California, including six in genus Amazona. Los Angeles has been called a sanctuary for this endangered species, with a population of around 3,000 that is estimated to meet or exceed the remaining wild population in Mexico. Area residents say that although the birds annoy with their loud calls, they also inspire local pride and identity.
+
+
+== Behavior ==
+They gather in large flocks being noisiest in the morning and evening. The characteristic screeching heard of these birds usually occurs when they travel in a large flock to a new feeding area. Their diet consists of seeds, fruits, flowers and nectar. Red-crowned amazons nest in tree cavities, like most other parrots. Amazons are one of the easiest parrots to read the behavior of, as their eye color shows their pinning exceptionally well. Red-crowned amazons pin their eyes when they are excited, either positively or negatively, about something in their environment. It is easy to make out the dilations of the pupil against the bright iris. This pinning, combined with different behavioral signs, can let a fellow parrot or an owner know how the parrot is feeling. An angry parrot may fan its tail feathers while a content, affectionate parrot may purr, or bend their head down to be scratched.
+
+
+== Reproduction ==
+Red-crowned amazon parrots reach sexual maturity at about five years old. It takes the female approximately 28 days to incubate her eggs, at an average of four eggs per clutch. Fledging begins at nine weeks old. In the wild, these parrots mate for life and find tree cavities near other members of their flock, creating a breeding group known as a colony. They will return to the same cavity every year to raise chicks unless that cavity was previously poached or they did not have reproductive success there for a different reason. 
+
+
+== Aviculture ==
+These parrots are often kept as pets and can be very affectionate and playful when given the attention they need from their owners. Although some are excellent talkers and copy voices, they are best at mimicking sounds that stand out to them, such as the microwave, telephone or other pets. Many owners report a streak of mischief due to their heightened curiosity. Red-crowned amazons can live 50+ years in captivity, with some extending over 70 years old if properly cared for.Common challenges associated with owning this type of parrot includes being able to provide enough exercise for it and convincing it to eat a varied, healthy diet, close to the diet it would have in the wild. Amazons are known for becoming sedentary if not provided enough stimuli, and this can lead to health issues, such as obesity. These birds are not regarded as overly sensitive and are actually one of the hardier large species to own as a pet because common stressors for other companion parrot species are coped with better and neurotic behaviors due to stress or depression, such as feather plucking, are infrequent when compared to other species. Another challenge some owners face is the hormonal bluffing during the breeding season (spring) for adolescents that causes some parrots, especially males, to be more prone to nipping their owners, biting anyone who is not their favorite person and screaming. These hormonal outbursts decrease with age.

+The axolotl (; from Classical Nahuatl: āxōlōtl [aːˈʃoːloːtɬ] (listen)), Ambystoma mexicanum, is a paedomorphic salamander closely related to the tiger salamander. Axolotls are unusual among amphibians in that they reach adulthood without undergoing metamorphosis. Instead of taking to the land, adults remain aquatic and gilled. The species was originally found in several lakes underlying what is now Mexico City, such as Lake Xochimilco and Lake Chalco. These lakes were drained by Spanish settlers after the conquest of the Aztec Empire, leading to the destruction of much of the axolotl’s natural habitat.
+Axolotls should not be confused with the larval stage of the closely related tiger salamander (A. tigrinum), which are widespread in much of North America and occasionally become paedomorphic. Neither should they be confused with mudpuppies (Necturus spp.), fully aquatic salamanders from a different family that are not closely related to the axolotl but bear a superficial resemblance.As of 2020, wild axolotls were near extinction due to urbanization in Mexico City and consequent water pollution, as well as the introduction of invasive species such as tilapia and perch. They are listed as critically endangered in the wild, with a decreasing population of around 50 to 1,000 adult individuals, by the International Union for Conservation of Nature and Natural Resources (IUCN) and are listed under Appendix II of the Convention on International Trade in Endangered Species (CITES). Axolotls are used extensively in scientific research due to their ability to regenerate limbs, gills and parts of their eyes and brains. Axolotls were also sold as food in Mexican markets and were a staple in the Aztec diet.
+
+
+== Description ==
+
+A sexually mature adult axolotl, at age 18–27 months, ranges in length from 15 to 45 cm (6 to 18 in), although a size close to 23 cm (9 in) is most common and greater than 30 cm (12 in) is rare. Axolotls possess features typical of salamander larvae, including external gills and a caudal fin extending from behind the head to the vent. External gills are usually lost when salamander species mature into adulthood, although the axolotl maintains this feature. This is due to their neoteny evolution, where axolotls are much more aquatic than other salamander species.Their heads are wide, and their eyes are lidless. Their limbs are underdeveloped and possess long, thin digits. Males are identified by their swollen cloacae lined with papillae, while females are noticeable for their wider bodies full of eggs. Three pairs of external gill stalks (rami) originate behind their heads and are used to move oxygenated water. The external gill rami are lined with filaments (fimbriae) to increase surface area for gas exchange. Four-gill slits lined with gill rakers are hidden underneath the external gills, which prevent food from entering and allow particles to filter through.
+
+Axolotls have barely visible vestigial teeth, which develop during metamorphosis. The primary method of feeding is by suction, during which their rakers interlock to close the gill slits. External gills are used for respiration, although buccal pumping (gulping air from the surface) may also be used to provide oxygen to their lungs. Buccal pumping can occur in a two-stroke manner that pumps air from the mouth to the lungs, and with four-stroke that reverses this pathway with compression forces.
+
+Axolotls have four pigmentation genes; when mutated they create different color variants. The normal wild-type animal is brown/tan with gold speckles and an olive undertone. The five more common mutant colors are leucistic (pale pink with black eyes), golden albino (golden with gold eyes), xanthic (grey with black eyes), albino (pale pink/white with red eyes) which is more common in axolotls than some other creatures, and melanoid (all black/dark blue with no gold speckling or olive tone). In addition, there is wide individual variability in the size, frequency, and intensity of the gold speckling and at least one variant that develops a black and white piebald appearance on reaching maturity. Because pet breeders frequently cross the variant colors, double homozygous mutants are common in the pet trade, especially white/pink animals with pink eyes that are double homozygous mutants for both the albino and leucistic trait. Axolotls also have some limited ability to alter their color to provide better camouflage by changing the relative size and thickness of their melanophores.
+
+
+== Habitat and ecology ==
+
+The axolotl is native only to the freshwater of Lake Xochimilco and Lake Chalco in the Valley of Mexico. Lake Chalco no longer exists, having been drained as a flood control measure, and Lake Xochimilco remains a remnant of its former self, existing mainly as canals. The water temperature in Xochimilco rarely rises above 20 °C (68 °F), although it may fall to 6–7 °C (43–45 °F) in the winter, and perhaps lower.Surveys in 1998, 2003, and 2008 found 6,000, 1,000, and 100 axolotls per square kilometer in its Lake Xochimilco habitat, respectively. A four-month-long search in 2013, however, turned up no surviving individuals in the wild. Just a month later, two wild ones were spotted in a network of canals leading from Xochimilco.The wild population has been put under heavy pressure by the growth of Mexico City. The axolotl is currently on the International Union for Conservation of Nature's annual Red List of threatened species. Non-native fish, such as African tilapia and Asian carp, have also recently been introduced to the waters. These new fish have been eating the axolotls' young, as well as their primary source of food.Axolotls are members of the tiger salamander, or Ambystoma tigrinum, species complex, along with all other Mexican species of Ambystoma. Their habitat is like that of most neotenic species—a high-altitude body of water surrounded by a risky terrestrial environment. These conditions are thought to favor neoteny. However, a terrestrial population of Mexican tiger salamanders occupies and breeds in the axolotl's habitat.The axolotl is carnivorous, consuming small prey such as mollusks, worms, insects, other arthropods, and small fish in the wild. Axolotls locate food by smell, and will "snap" at any potential meal, sucking the food into their stomachs with vacuum force.
+
+
+== Use as a model organism ==
+
+Today, the axolotl is still used in research as a model organism, and large numbers are bred in captivity. They are especially easy to breed compared to other salamanders in their family, which are rarely captive-bred due to the demands of terrestrial life. One attractive feature for research is the large and easily manipulated embryo, which allows viewing of the full development of a vertebrate. Axolotls are used in heart defect studies due to the presence of a mutant gene that causes heart failure in embryos. Since the embryos survive almost to hatching with no heart function, the defect is very observable. The axolotl is also considered an ideal animal model for the study of neural tube closure due to the similarities between human and axolotl neural plate and tube formation; the axolotl's neural tube, unlike the frog's, is not hidden under a layer of superficial epithelium. There are also mutations affecting other organ systems some of which are not well characterized and others that are. The genetics of the color variants of the axolotl have also been widely studied.
+
+
+=== Regeneration ===
+The feature of the axolotl that attracts most attention is its healing ability: the axolotl does not heal by scarring and is capable of the regeneration of entire lost appendages in a period of months, and, in certain cases, more vital structures, such as tail, limb, central nervous system, and tissues of the eye and heart. They can even restore less vital parts of their brains. They can also readily accept transplants from other individuals, including eyes and parts of the brain—restoring these alien organs to full functionality. In some cases, axolotls have been known to repair a damaged limb, as well as regenerating an additional one, ending up with an extra appendage that makes them attractive to pet owners as a novelty. In metamorphosed individuals, however, the ability to regenerate is greatly diminished. The axolotl is therefore used as a model for the development of limbs in vertebrates. There are three basic requirements for regeneration of the limb: the wound epithelium, nerve signaling, and the presence of cells from the different limb axes. A wound epidermis is quickly formed by the cells to cover up the site of the wound. In the following days, the cells of the wound epidermis divide and grow quickly forming a blastema, which means the wound is ready to heal and undergo patterning to form the new limb.
+It is believed that during limb generation, axolotls have a different system to regulate their internal macrophage level and suppress inflammation, as scarring prevents proper healing and regeneration. However, this belief has been questioned by other studies. Axolotl’s regenerative properties leave the species as the perfect model to study the process of stem cells and its own neoteny feature. Current research can record specific examples of these regenerative properties through tracking cell fates and behaviors, lineage tracing skin triploid cell grafts, pigmentation imaging, electroporation, tissue clearing and lineage tracing from dye labeling. The newer technologies of germline modification and transgenesis are better suited for live imaging the regenerative processes that occur for axolotls.
+
+
+=== Genome ===
+The 32 billion base pair long sequence of the axolotl's genome was published in 2018 and was the largest animal genome completed at the time. It revealed species-specific genetic pathways that may be responsible for limb regeneration. Although the axolotl genome is about 10 times as large as the human genome, it encodes a similar number of proteins, namely 23,251 (the human genome encodes about 20,000 proteins). The size difference is mostly explained by a large fraction of repetitive sequences, but such repeated elements also contribute to increased median intron sizes (22,759 bp) which are 13, 16 and 25 times that observed in human (1,750 bp), mouse (1,469 bp) and Tibetan frog (906 bp), respectively.
+
+
+=== Neoteny ===
+
+When most amphibians are young, they live in water, and they use gills that can breathe in the water. When they become adults, they go through a process called metamorphosis, in which they lose their gills and start living on land. However, the axolotl is unusual in that it has a lack of thyroid stimulating hormone, which is needed for the thyroid to produce thyroxine in order for the axolotl to go through metamorphosis; therefore, it keeps its gills and lives in water all its life, even after it becomes an adult and is able to reproduce. Its body has the capacity to go through metamorphosis if given the necessary hormone, but axolotls do not produce it, and must be exposed to it from an external source, after which an axolotl undergoes an artificially-induced metamorphosis and begins living on land. One method of artificial metamorphosis induction is through an injection of iodine, which is used in the production of thyroid hormones.
+An axolotl undergoing metamorphosis experiences a number of physiological changes that help them adapt to life on land. These include increased muscle tone in limbs, the absorption of gills and fins into the body, the development of eyelids, and a reduction in the skin's permeability to water, allowing the axolotl to stay more easily hydrated when on land. The lungs of an axolotl, though present alongside gills after reaching non-metamorphosed adulthood, develop further during metamorphosis.An axolotl that has gone through metamorphosis resembles an adult plateau tiger salamander, though the axolotl differs in its longer toes. The process of artificially inducing metamorphosis can often result in death during or even following a successful attempt, and so casual hobbyists are generally discouraged from attempting to induce metamorphosis in pet axolotls.Neoteny is the term for reaching sexual maturity without undergoing metamorphosis. Many other species within the axolotl's genus are also either entirely neotenic or have neotenic populations. Sirens and Necturus are other neotenic salamanders, although unlike axolotls, they cannot be induced to metamorphose by an injection of iodine or thyroxine hormone.
+The genes responsible for neoteny in laboratory animals may have been identified; however, they are not linked in wild populations, suggesting artificial selection is the cause of complete neoteny in laboratory and pet axolotls.Six adult axolotls (including a leucistic specimen) were shipped from Mexico City to the Jardin des Plantes in Paris in 1863. Unaware of their neoteny, Auguste Duméril was surprised when, instead of the axolotl, he found in the vivarium a new species, similar to the salamander. This discovery was the starting point of research about neoteny. It is not certain that Ambystoma velasci specimens were not included in the original shipment. Vilem Laufberger in Prague used thyroid hormone injections to induce an axolotl to grow into a terrestrial adult salamander. The experiment was repeated by Englishman Julian Huxley, who was unaware the experiment had already been done, using ground thyroids. Since then, experiments have been done often with injections of iodine or various thyroid hormones used to induce metamorphosis.Neoteny has been observed in all salamander families in which it seems to be a survival mechanism, in aquatic environments only of mountain and hill, with little food and, in particular, with little iodine. In this way, salamanders can reproduce and survive in the form of a smaller larval stage, which is aquatic and requires a lower quality and quantity of food compared to the big adult, which is terrestrial. If the salamander larvae ingest a sufficient amount of iodine, directly or indirectly through cannibalism, they quickly begin metamorphosis and transform into bigger terrestrial adults, with higher dietary requirements. In fact, in some high mountain lakes there live dwarf forms of salmonids that are caused by deficiencies in food and, in particular, iodine, which causes cretinism and dwarfism due to hypothyroidism, as it does in humans.
+
+
+== Captive care ==
+
+The axolotl is a popular exotic pet like its relative, the tiger salamander (Ambystoma tigrinum). As for all poikilothermic organisms, lower temperatures result in slower metabolism and a very unhealthily reduced appetite. Temperatures at approximately 16 °C (61 °F) to 18 °C (64 °F) are suggested for captive axolotls to ensure sufficient food intake; stress resulting from more than a day's exposure to lower temperatures may quickly lead to disease and death, and temperatures higher than 24 °C (75 °F) may lead to metabolic rate increase, also causing stress and eventually death. Chlorine, commonly added to tapwater, is harmful to axolotls. A single axolotl typically requires a 150-litre (40-US-gallon) tank. Axolotls spend the majority of the time at the bottom of the tank.
+
+Salts, such as Holtfreter's solution, are often added to the water to prevent infection.In captivity, axolotls eat a variety of readily available foods, including trout and salmon pellets, frozen or live bloodworms, earthworms, and waxworms. Axolotls can also eat feeder fish, but care should be taken as fish may contain parasites.Substrates are another important consideration for captive axolotls, as axolotls (like other amphibians and reptiles) tend to ingest bedding material together with food and are commonly prone to gastrointestinal obstruction and foreign body ingestion. Some common substrates used for animal enclosures can be harmful for amphibians and reptiles. Gravel (common in aquarium use) should not be used, and is recommended that any sand consists of smooth particles with a grain size of under 1mm. One guide to axolotl care for laboratories notes that bowel obstructions are a common cause of death, and recommends that no items with a diameter below 3 cm (or approximately the size of the animal's head) should be available to the animal.There is some evidence that axolotls might seek out appropriately-sized gravel for use as gastroliths based on experiments conducted at the University of Manitoba axolotl colony, but these studies are outdated and not conclusive. As there is no conclusive evidence pointing to gastrolith use, gravel should be avoided due to the high risk of impaction.
+
+
+== Cultural significance ==
+The species is named after the Aztec deity Xolotl, who transformed himself into an axolotl. They continue to play an outsized cultural role in Mexico, and have appeared in cartoons and murals.In 2020, it was announced that the axolotl will be featured on the new design for Mexico's 50-peso banknote, along with images of maize and chinampas.

+Meller's duck (Anas melleri) is a species of the dabbling duck genus Anas. It is endemic to eastern Madagascar. Although a population was established on Mauritius in the mid-18th century, this is on the verge of extinction due to habitat loss and competition by feral domestic ducks. The species name of this species is after the botanist Charles James Meller, and its generic name is from the Latin for "duck".
+
+
+== Description ==
+
+The Meller's duck resembles a large female mallard. At 55–65 centimetres (22–26 in), it averages slightly larger than a mallard and is at the top size for the genus Anas. However, as opposed to most mallard relatives, they lack a supercilium. The speculum feathers are green as in some of its relatives, but unlike in these, it is bordered white as in the mallard. Its body is dark brown with narrow paler fringes to feathers on upper parts and wider fringes on lower parts.  Its bill is pale grey, with dark patches at the base, and is larger than normal. Its feet and legs are orange.
+
+
+== Behaviour ==
+Meller's duck breeds apparently during most of the year except May–June on Madagascar, dependent on local conditions; the Mauritian population has been recorded to breed in October and November. Unlike most of their closer relatives—with the exception of the African black duck—they are fiercely territorial during the breeding season; furthermore, pairs remain mated until the young are independent.
+
+
+== Conservation ==
+This species is listed as an endangered species by the IUCN Red List. The Lac Alaotra wetlands, where historically the largest number of these birds was to be found, have suffered habitat destruction on a large scale in the latter half of the 20th century, and local waterbird populations have declined dramatically. The Madagascar pochard was rediscovered in 2006, though not in the Lac Alaotra area.The conservation of this species was long hampered by its—entirely erroneous, see below—dismissal as a variant of the mallard which deserved no special interest. Due to its drab plumage and territorial habits, this species is not very popular among aviculturalists, although it reproduces readily in captivity like most ducks if enough space and good habitat are provided. Although a captive breeding program exists (part of the European Endangered Species Programme), the species is not very often kept in zoos either; it can be more frequently seen in Europe, such as in EEP members Cologne Zoo, Edinburgh Zoo, Durrell Wildlife Park, and Zürich Zoo.
+
+
+== Relations ==
+Due to the outward similarity of Meller's duck to the female mallard, it was commonly placed close to that species. Based on records of quasi-forced hybridization under unnatural conditions, it was even proposed to be a mere color morph of the mallard.Nowadays, it is regarded as one of the most distinct species in the mallard group, based on behavioural and mtDNA D-loop sequence comparisons. Its closest relatives is apparently the yellow-billed duck, another early divergence of the mallard clade, in which these species and the African black duck are basal, but the exact relationships of Meller's and the yellow-billed ducks to that species are fairly obscure. (The dates in these studies are probably far too recent in the face of the Early Pleistocene fossil record of mallards and the crude methodology used to arrive at the estimate.)

+The hyacinth macaw (Anodorhynchus hyacinthinus), or hyacinthine macaw, is a parrot native to central and eastern South America. With a length (from the top of its head to the tip of its long pointed tail) of about one meter it is longer than any other species of parrot. It is the largest macaw and the largest flying parrot species; the flightless kākāpō of New Zealand outweighs it at up to 3.5 kg. While generally easily recognized, it could be confused with the smaller Lear's macaw. Habitat loss and the trapping of wild birds for the pet trade have taken a heavy toll on their population in the wild, so the species is classified as Vulnerable on the International Union for Conservation of Nature's Red List, and it is protected by its listing on Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
+
+
+== Taxonomy ==
+English physician, ornithologist, and artist John Latham first described the hyacinth macaw in 1790 under the binomial name Psittacus hyacinthinus. Tony Pittman in 2000 hypothesized that although the illustration in this work appears to be of an actual hyacinthine macaw, Latham's description of the length of the bird might mean he had measured a specimen of Lear's macaw instead. However, Latham's description was based on a taxidermic specimen, which was the only one Latham knew to exist up until 1822. It was prepared from a living animal originally belonging to Lord Orford, and given to the land agent Parkinson for display in the Leverian Museum after it died.Nonetheless, Latham mentions another bird, which he calls the 'blue maccaw', supposedly the same size. This blue macaw was already described in Latham's 1781 volume of his A general synopsis of birds as merely a variety of the blue and yellow macaw, and was previously figured in the work of Mathurin Jacques Brisson (1760), Patrick Browne (1756) and Eleazar Albin (1738) as a macaw found in Jamaica. Albin, Browne and Brisson all reference even older authors and state the bird also occurs on the mainland, and Albin states this bird is the female version of the scarlet macaw. Latham mentions that the provenance of parrots in general was often confused by the fact that the birds were much traded across the world for the purposes of sale.It is one of two extant and one probably extinct species of the South American macaw genus Anodorhynchus.
+
+
+== Description ==
+The largest parrot by length in the world, the hyacinth macaw is 1 m (3 ft 3 in) long from the tip of its tail to the top of its head and weighs 1.2–1.7 kg (2 lb 10 oz – 3 lb 12 oz). Each wing is 38.8–42.5 cm (15+1⁄4–16+3⁄4 in) long. The tail is long and pointed. Its feathers are entirely blue, lighter above. However, the neck feathers can sometimes be slightly grey. The ring around the parrots eyes and area just underneath the beak are a strong, vibrant yellow.
+
+		
+		
+		
+		
+
+
+== Ecology ==
+A main predator is the toco toucan, which consumes a large percentage of the eggs. Eggs are also regularly preyed on by corvids such as jays and crows, opossums, skunks and coatis. The young are parasitized by larvae of flies of the genus Philornis.
+
+
+== Behaviour ==
+
+
+=== Food and feeding ===
+
+The majority of the hyacinth macaw diet is composed of the nuts from specific palm species, such as acuri and bocaiuva palms. They have very strong beaks for eating the kernels of hard nuts and seeds. Their strong beaks are even able to crack coconuts, the large brazil nut pods, and macadamia nuts. The birds also boast dry, smooth tongues with a bone inside them that makes them an effective tool for tapping into fruits. The acuri nut is so hard, the parrots cannot feed on it until it has passed through the digestive system of cattle. In addition, they eat fruits and other vegetable matter. The hyacinth macaw generally eats fruits, nuts, nectar, and various kinds of seeds. Also, they travel for the ripest of foods over a vast area.In the Pantanal, hyacinth macaws feed almost exclusively on the nuts of Acrocomia aculeata and Attalea phalerata palm trees. This behaviour was recorded by the English naturalist Henry Walter Bates in his 1863 book The Naturalist on the River Amazons, where he wrote that
+
+It flies in pairs, and feeds on the hard nuts of several palms, but especially of the Mucuja (Acrocomia lasiospatha). These nuts, which are so hard as to be difficult to break with a heavy hammer, are crushed to a pulp by the powerful beak of this macaw.
+Charles Darwin remarked on Bates's account of the species, calling it a "splendid bird" with its "enormous beak" able to feed on these palm nuts.In captivity, the palm nuts native to the hyacinth macaw's natural habitat are often not readily available. In these circumstances the macadamia nut (which is native to Australia) is a suitable, nutritious and readily-accepted alternative. Coincidentally, the hyacinth macaw is one of the only birds with the necessary jaw strength to open the nut, which requires 300psi of pressure to crack the shell.
+
+
+=== Tool use ===
+Limited tool use has been observed in both wild and captive hyacinth macaws. Reported sightings of tool use in wild parrots go as far back as 1863. Examples of tool use that have been observed usually involve a chewed leaf or pieces of wood. Macaws often incorporate these items when feeding on harder nuts. Their use allows the nuts the macaws eat to remain in position (prevent slipping) while they gnaw into it. It is not known whether this is learned social behavior or an innate trait, but observation on captive macaws shows that hand-raised macaws exhibit this behavior, as well. Comparisons show that older macaws were able to open seeds more efficiently.
+
+
+=== Reproduction ===
+
+Nesting takes place between July and December, with nests constructed in tree cavities or cliff faces depending on the habitat. In the Pantanal region, 90% of nests are constructed in the manduvi tree (Sterculia apetala). The hyacinth macaw depends on the toucan for its livelihood. The toucan contributes largely to seed dispersal of the manduvi tree that the macaw needs for reproduction. However, the toucan is responsible for dispersing 83 % of the seeds of Sterculia apetala, but also consumes 53% of eggs preyed. Hollows of sufficient size are only found in trees around 60 years of age or older, and competition is fierce. Existing holes are enlarged and then partially filled with wood chips. The clutch size is one or two eggs, although usually only one fledgling survives as the second egg hatches several days after the first, and the smaller fledgling cannot compete with the firstborn for food. A possible explanation for this behaviour is what is called the insurance hypothesis. The macaw lays more eggs than can be normally fledged to compensate for earlier eggs that failed to hatch or firstborn chicks that did not survive. The incubation period lasts about a month, and the male tends to his mate whilst she incubates the eggs. The chicks leave the nest, or fledge, around 110 days of age, and remain dependent on their parents until six months of age. They are mature and begin breeding at seven years of age.
+
+
+=== General traits ===
+Hyacinth macaws are the longest psittacine. They are also very even-tempered and can be calmer than other macaws, being known as "gentle giants". An attending veterinarian must be aware of specific nutritional needs and pharmacologic sensitivities when dealing with them. Possibly due to genetic factors or captive rearing limitations, this species can become neurotic/phobic, which is problematic.
+
+
+== Distribution and habitat ==
+The hyacinth macaw occurs today in three main areas in South America: In the Pantanal region of Brazil, and adjacent eastern Bolivia and northeastern Paraguay, in the cerrado regions of the eastern interior of Brazil (Maranhão, Piauí, Bahia, Tocantins, Goiás, Mato Grosso, Mato Grosso do Sul, and Minas Gerais), and in the relatively open areas associated with the Tocantins River, Xingu River, Tapajós River, and the Marajó island in the eastern Amazon Basin of Brazil. Smaller, fragmented populations may occur in other areas.Over the last few decades the known range in Bolivia has grown. It is well known from the far southeast of the country near the tri-national border point with Brazil and Paraguay, where it is considered an emblematic symbol of the region, and locals often feed the macaws maize, like chickens. In the early 1990s it became apparent the species also occurred in the remote Noel Kempff Mercado National Park area a few hundred kilometres northward. Most of the Bolivian population of this macaw is thought to be found in the San Matías Integrated Management Natural Area, an area with extensive pantanal (swamp). Censuses conducted within in 2008, 2009, 2011 and 2014, revealed stable population numbers: respectively 231, 107, 134, and 166. Bird counts in such a swampy and difficult to navigate terrain are inherently inadequate. The censuses were performed by visiting locations with previous reported sightings, however, it was not always possible to visit all sites, coverage varied. Thus in 2011 the earlier estimated population of about 300 birds in this area was considered to be largely accurate. A 2014 study which correlated sightings to habitat and extrapolated this over a larger area found the birds occur in the northern part of the Natural Area, and a similar population likely also occurs in an equally sized area to the north of this, outside of the Natural Area. In a 2018 Mongabay Latam article, park rangers relate that there is anecdotal evidence the population was increasing and spreading, as more sightings were being reported by local inhabitants and the bird was now confirmed for the first time in a number of adjacent municipalities.The hyacinth macaw has escaped or been deliberately released in to Florida, USA, but there is no evidence that the population is breeding and may only persist due to continuing releases or escapes.It prefers semi-open, somewhat wooded habitats. It usually avoids dense, humid forest, and in regions dominated by such habitats, it is generally restricted to the edge or relatively open sections (e.g. along major rivers). In different areas of their range, these parrots are found in savannah grasslands, in dry thorn forest known as caatinga, and in palm stands or swamps, particularly the moriche palm (Mauritia flexuosa).A 2014 Bolivian study in San Matías Integrated Management Natural Area which correlated sightings to habitat found that areas including seasonally inundated savannas, wetlands and anthropogenic areas habitats interspersed with a mosaic of savannas, were the best indicators for the presence of the macaws. The most preferred habitat by far was anthropogenic, which are primarily cattle ranches practising extensive grazing in this area. The authors, however, were not very impressed by these results, and cautioned the methodology might be flawed.
+
+
+== Conservation and threats ==
+
+The conservation status of the hyacinth macaw is assessed as vulnerable. The first proper estimate of its total wild population was published by Munn in 1987 as 3,000 individuals, with a range of 2,500 to 5,000. Yamashita estimated the total world captive population as equal or slightly more than that in 1988. An anonymous blogger associated with the NGO the World Wildlife Fund claimed in 2004 that an estimated 10,000 birds were taken from the wild in the 1980s, of which half were destined for the Brazilian market, and that the wild population had increased to 6,500.The hyacinth macaw is protected by law in Brazil and Bolivia, and commercial export of wild sourced specimens is banned by its listing on Appendix I of the CITES. A number of long-term studies and conservation initiatives are in place; the Hyacinth Macaw Project in the Brazilian state of Mato Grosso do Sul has carried out important research by ringing individual birds, and has created a number of artificial nests to compensate for the small number of sites available in the region.The Minnesota Zoo with BioBrasil and the World Wildlife Fund are involved in hyacinth macaw conservation.
+
+
+=== Threats ===
+Throughout the macaw's range, habitat is being lost or altered due to the introduction of cattle ranching and mechanised agriculture, and the development of hydroelectric schemes. Annual grass fires set by farmers can destroy nest trees, and regions previously inhabited by this macaw are now unsuitable also due to agriculture and plantations. Locally, it has been hunted for food, and the Kayapo Indians of Gorotire in south-central Brazil use its feathers to make headdresses and other ornaments. While overall greatly reduced in numbers, it remains locally common in the Brazilian Pantanal, where many ranch-owners now protect the macaws on their land.Parrots as a whole, being of the family Psittacidae, are some of the most threatened birds in the world. This family has the most endangered species of all bird families, especially in the neotropics, the natural home of the hyacinth macaw, where 46 of 145 species are at a serious risk of global extinction. This species qualifies as 'Vulnerable' on the IUCN Red List because the population has suffered rapid reductions with the remaining threats of illegal trapping for the cage bird trade and habitat loss A few serious threats to the survival of the species in the Pantanal include human activities, mainly those resulting in habitat loss, the burning of land for pasture maintenance, and illegal trapping The exceptionally noisy, fearless, curious, sedentary, and predictable nature of this species, along with its specialization to only one or two species of palm in each part of its range, makes them especially vulnerable to capture, shooting, and habitat destruction.Although the species has a low genetic variability, it does not necessarily pose a threat to their survival. This genetic structure accentuates the need for protection of hyacinth macaws from different regions to maintain their genetic diversity. Nevertheless, the most important factors negatively affecting the wild population prove to be habitat destruction and nest poaching.In the Pantanal, habitat loss is largely contributed to the creations of pastures for cattle, while in many other regions, it is the result of clearing land for colonization. Similarly, large areas of habitat in Amazonia have been lost for cattle ranching and hydroelectric power schemes on the Tocantins and Xingu Rivers. Many young manduvi trees are then being grazed on by cattle or burnt by fire, and the Gerias is speedily being converted to land for mechanized agriculture, cattle ranching, and exotic tree plantations. Annual grass fires set by farmers destroy a number of nest trees, and the rise of agriculture and plantations has made habitats formerly populated by the macaws unsuitable to maintain their livelihoods. Moreover, increase in commercial demand for feather art by the Kayapo Indians threatens the species, as up to 10 macaws are needed to make a single headdress.In the event of the macaws being taken from their natural environment, a variety of factors alter their health such as inadequate hygiene conditions, feeding, and overpopulation during the illegal practice of pet trade. Once birds are captured and brought into captivity, their mortality rates can become very high. Records reveal a Paraguayan dealer receiving 300 unfeathered young in 1972, with all but three not surviving. Due to the poor survival rates of the young, poachers concentrate more heavily on adult birds, which depletes the population at a rapid pace.According to Article 111 of Bolivian Environmental Law #1333, all persons involved in the trade, capture, and transportation without authorization of wild animals will suffer a two-year prison sentence, along with a fine equivalent to 100% of the value of the animal. While many trackers have been arrested, the illegal pet trade still largely continues in Santa Cruz, Bolivia. Unfortunately, animal trafficking is not necessarily viewed as a priority in the city, leaving national departmental and municipal governments unwilling to halt the trade in city centers, and local police reluctant to get involved. This ideology has in turn resulted in a lack of enforcement regarding trade in both CITES-restricted species and threatened species, with little to no restrictions regarding humane treatment of the animals, disease control, or proper hygiene. In the trade centers, the hyacinth macaw demanded the highest price of US$1,000, proving it to be a very desirable and valued bird in the pet trade industry.
+
+
+=== Conservation steps taken to preserve the hyacinth macaw ===
+In 1989, the European Endangered Species Programme for the hyacinth macaw was founded as a result of concerns about the status of the wild population and the lack of successful breeding in captivity. Breeding in captivity still remains difficult, being that hand-reared hyacinth macaw offspring have demonstrated to have higher mortality rates, especially within the first month of life. Additionally, they have a higher incidence of acute crop stasis than other macaw species due, in part, to their specific dietary requirements. The hyacinth macaw is protected by law in Brazil and Bolivia, and international trade is prohibited by its listing on Appendix I of the CITES. Appendix I has banned exporting the bird in all countries of origin, and several studies and conservational initiatives have been taken. The Hyacinth Macaw Project in the Caiman Ecological Refuge, located in the Pantanal, has employed artificial nests and chick management techniques, along with effectively raising awareness among cattle ranchers. Many ranch owners in the Pantanal and Gerais, to protect the birds, no longer allow trappers on their properties.A number of conservation actions have been proposed, including the study of the current range, population status, and extent of trading in different parts of its range. Additionally, propositions have been made to assess the effectiveness of artificial nest boxes, enforce legal measures preventing trade, and experiment with ecotourism at one or two sites to encourage donors. Furthermore, the Hyacinth Macaw Project in Mato Grosso do Sul has carried out important research by ringing individual birds and has created a number of artificial nests to compensate for the small number of sites available in the region. Furthermore, proposals to list the species as Endangered under the U.S. Endangered Species Act have been made to further protective measures in the US and to create Bolivian and Paraguayan trade management authorities under presidential control.
+
+
+=== Long-term prospects ===
+Each of the three main populations should be managed as a separate biological entity so as to avoid numbers dropping below 500. While the birds may be in decline in the wild, notably higher populations of captive macaws are being held in zoos and private collections. If success in managing and replanting the macaw's food trees and erecting nest boxes as an experiment in the Pantanals is seen, the species could survive. Survival rates could also be enhanced if ranch owners would leave all large and potential nest trees standing and eliminate all trapping on their properties. Ultimately, should these factors work in tandem with erection of nest boxes, fencing off of certain saplings, and the planting of others, the long-term prospects of the hyacinth macaw species would be greatly improved.
+
+
+== Aviculture ==
+The hyacinth macaw is sometimes kept as a companion parrot. Not recommended for novice bird-keepers, this bird requires large amounts of space, regular exercise and a custom-built stainless steel cage, as its powerful beak can easily destroy most commercially available parrot cages. In order to remain healthy, the species requires regular social interaction and play with humans or other birds. This large macaw, like most parrots has a natural inclination to chew objects and due to its physical size and strength, can cause considerable damage. It is recommended that an entire room of the owner's home is set aside for use by the bird, which should be provided with plenty of safe, destroyable wooden and leather objects to keep it amused. It is also a very expensive pet: US$10,000 is not an uncommon price for a young hyacinth macaw. The World Parrot Trust recommends that the hyacinth macaw should not be kept permanently indoors and that it should have access to an enclosure of at least 15m (50 ft) for part of the year.This bird is often described as "gentle". It is not generally an aggressive bird and it appears to enjoy interacting playfully with humans. It can cause bite injuries simply from playfully "mouthing" its owner, however, and this behavior should be discouraged with training begun when the bird is young.The hyacinth macaw can learn to talk, but it is not as gifted in that area as some other species. Nonetheless, it is an intelligent bird that may learn to use words and phrases in the correct context. It can live for over 50 years in captivity.

+The Florida softshell turtle (Apalone ferox) is a species of softshell turtle native to the Southeastern United States.
+
+
+== Geographic range ==
+The Florida softshell turtle is found primarily in the state of Florida, but it also ranges to southern sections of South Carolina, Georgia, and Alabama. It is the only species of softshell turtle whose range spans the entire Florida peninsula. They are native to the southeastern United States. Out of the Trionychidae family, the Florida softshell occupies the smallest range.
+
+
+=== Habitat use ===
+The Florida softshell turtle is a widespread species and occupies almost every freshwater habitat, even tolerating some brackish environments; however, it is not often found in water with strong currents, preferring habitats with slow-moving or still water. These different habitats include swamps, lakes, marshes, wet prairies, small rivers, creeks, and even ponds formed in man-made ditches or sinkholes.
+
+
+== Description ==
+The Florida softshell turtle is a large turtle with a flattened, pancake-like body, a long neck, an elongated head with a long snorkel-like nose, and large webbed feet, each with three claws. While most turtles have hard shells composed of scutes, the Florida softshell has a cartilaginous carapace covered in leathery skin. Ranging from olive green to dark brown, it has the darkest coloration of all the softshell species that inhabit Florida (other species include Apalone mutica calvata and Apalone spinifera aspera). It is also characterized by a white or cream-colored underside. This color pattern is known as countershading and is a form of camouflage to conceal turtles from potential predators. It is also the largest species of softshell turtle found in Florida and all of North America, ranging from 15 to 76 cm (5.9 to 29.9 in) in length. The Florida softshell also exhibits significant sexual size dimorphism. Adult females are often 3-5x larger than males. Males have a carapace length and body weight averaging about 35 cm (14 in) and 2.68 kg (5.9 lb) respectively. Nesting adult females were found to average 6.65 kg (14.7 lb) in weight and measure 40.1 cm (15.8 in) in carapace length, with the record weight documented at 43.6 kg (96 lb). However, males tend to have longer tails than their female counterparts (3 cm longer than a female of the same size). Hatchlings have a lighter carapace with yellow and orange markings and a carapacial rim. Stripes in the same color are also found on the face and neck. Their plastron is generally dark in color. As the turtle ages, these colors fade and are lost, resulting in the dark-brown coloration characteristic of adults.
+
+
+== Behavior ==
+The Florida softshell turtle is almost entirely aquatic, only emerging from the water to bask or to lay eggs. In the water, it prefers to bury itself in the sandy/muddy substrate. Like all softshells, it is very fast-moving in water and on land. While this species is omnivorous, its diet consists largely of meat, consuming mainly fish, insects, crustaceans, frogs and mollusks. It may also scavenge.
+
+
+== Reproduction ==
+
+
+=== Males ===
+The reproductive cycle of male Florida softshell turtles follows a postnuptial pattern, with a cycle of spring mating followed by spermatogenesis in the fall. The male will produce sperm during the fall and store that sperm in the epididymides through the winter. This stored sperm can then be utilized for copulation during the following spring mating season. Evidence suggests that they undergo spermatogenesis every year. Males of this species reach sexual maturity at small sizes (below 0.7 kg), allowing them to begin reproducing quickly following birth. This implies that some males may be able to reproduce as young as two years of age.
+
+
+=== Females ===
+While males consistently reach sexual maturity at small sizes, that size is larger and more variable in females. Some may reach maturity at a plastron length of 24 cm, and others may not mature until they reach a length closer to 30 cm. The onset of sexual maturity will occur anywhere from 5 – 8 years of age. The female nesting season can range anywhere from early April to early August, and incubation lasts an average of 60 – 90 days. In a study examining female reproduction, almost 10% of the females examined in a single breeding season showed signs of inactive ovaries, implying that, unlike males, females may not possess the ability to reproduce every year. Florida softshell females have the ability to produce an average of 4 – 5 egg clutches in a single breeding season, potentially producing a new clutch every three weeks. Florida softshell turtles have one of the highest annual egg production rates of any reptile. The study previously mentioned showed an average of over 20 eggs per clutch, with the largest clutch containing 38 eggs.
+
+
+== Ecology ==
+With a primarily carnivorous diet, adult Florida softshell turtles function as major predators in their aquatic ecosystems. Sitting high on the trophic scale, they generally function as secondary or tertiary consumers. However, alligators have been known to prey on the adults of the Florida softshell turtle, and raptors may take juveniles. Nest predators include the fish crow, foxes, raccoons, skunks, and river otters. At various lakes across the state of Florida (Okeechobee, Apopka, Griffin, and Jesup) scientists have observed Florida softshell females, as well as other turtle species (Pseudemys nelsoni, Kinosternon sp., and Sternotherus odoratus) laying their eggs in American alligator (Alligator mississippiensis) nests during the summer months. While the turtles may utilize vacant nests more often, they have also been known to lay eggs in occupied alligator nests. They use these nests more often in areas with limited nesting habitats and/or during years with heavier precipitation when high water levels and flooding further reduce the number of suitable nesting sites. Despite the Florida softshell's use of alligator nests, studies have shown the highest abundance of Florida softshell turtles to persist in lakes with little to no alligators as well as high primary productivity, suggesting a combination of top-down and bottom-up influences on softshell populations.
+
+
+== Anthropogenic threats ==
+The Florida softshell turtle is common throughout Florida and other parts of its range. However, wild populations are subject to various threats at the hands of humans. Some of these threats include commercial harvesting for meat, harvesting for the pet trade, and roadway mortalities.
+
+
+== Diet ==
+The Florida softshells are carnivores with their main diet consisting of small snails and fish. They also eat amphibians, insects, and mollusks and some waterfowl. These turtles will hunt, chase, and scavenge for prey.

+The blue-and-yellow macaw (Ara ararauna), also known as the blue-and-gold macaw, is a large South American parrot with mostly blue top parts and light orange underparts, with gradient hues of green on top of its head. It is a member of the large group of neotropical parrots known as macaws. It inhabits forest (especially varzea, but also in open sections of terra firme or unflooded forest), woodland and savannah of tropical South America. They are popular in aviculture because of their striking color, ability to talk, ready availability in the marketplace, and close bonding to humans. They can also live for 65–70 years.
+
+
+== Taxonomy ==
+The blue-and-yellow macaw was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae. He placed it with all the other parrots in the genus Psittacus and coined the binomial name Psittacus ararauna. This macaw is now one of the eight extant species placed in the genus Ara that was erected in 1799 by the French naturalist Bernard Germain de Lacépède. The genus name is from ará meaning "macaw" in the Tupi language of Brazil. The word is an onomatopoeia based on the sound of their call. The specific epithet ararauna comes from the Tupi Arára úna meaning "big dark parrot" for the hyacinth macaw. The word ararauna had been used by the German naturalist Georg Marcgrave in 1648 in his Historia Naturalis Brasiliae. The species is monotypic: no subspecies are recognised.
+
+
+== Description ==
+These birds can reach a length of 76–86 cm (30–34 in) and weigh 0.900–1.5 kg (2–3 lb), making them some of the larger members of their family. They are vivid in appearance with bright aqua blue feathers on the top of their body except for the head, which is lime colored. The bottom, however, is a rich deep yellow/light orange. Their beak is black, as well as the feathers under their chin. Its feet are of a gray color, save for black talons. The bird has white skin, with its face having nearly no feathers beside a few black ones spaced apart from each other forming a striped pattern around the eyes. The irises are pale light yellow.
+Blue-and-yellow macaws can live from 30 to 35 years in the wild, and reach sexual maturity between the ages of 3 and 6 years.Little variation in plumage is seen across the range. Some birds have a more orange or "butterscotch" underside color, particularly on the breast. This was often seen in Trinidad birds and others of the Caribbean area. The blue-and-yellow macaw uses its powerful beak for breaking nutshells, and for climbing up and hanging from trees. As well as nuts, it will also feed on seeds, fruits, vegetable matter, bark and leaves, also insects, snails and small animals.
+
+
+== Distribution and habitat ==
+This species occurs in Colombia, Venezuela, Peru, Brazil, Bolivia, Ecuador, and Paraguay. The range extends slightly into Central America, where it is restricted to Panama. While most breed in rural and forested areas, small numbers breed in urban cities such as Rondonópolis (Mato Grosso, Brazil), nesting in dead palms planted for ornamental purposes alongside city roads. Although they were nearly wiped out in Trinidad due to human activity during the 1970s, a recent programme of reintroduction has proved successful. Between 1999 and 2003, wild-caught blue-and-yellow macaws were translocated from Guyana to Trinidad, in an attempt to re-establish the species in a protected area around Nariva Swamp; despite this, the IUCN still lists them as extirpated from the country. A small breeding population descended from introduced birds is found in Puerto Rico, and another has inhabited Miami-Dade County, Florida, since the mid-1980s.
+
+
+== Breeding ==
+
+The blue-and-yellow macaw generally mates for life. They nest almost exclusively in dead palms and most nests are in Mauritia flexuosa palms. The female typically lays two or three eggs. The female incubates the eggs for about 28 days. One chick is dominant and gets most of the food; the others perish in the nest. Chicks fledge from the nest about 97 days after hatching. The male bird's color signals readiness for breeding. The brighter and bolder the colors, the better the chance of getting a mate.
+
+
+== Conservation and threats ==
+The blue-and-yellow macaw is on the verge of being extirpated in Paraguay, but it still remains widespread and fairly common in a large part of mainland South America. The species is therefore listed as Least Concern by BirdLife International.  It is listed on CITES Appendix II, trade restricted. Its current wild population is estimated to be between 100,000 and 200,000 individuals.
+
+
+== Aviculture ==
+Even well-tended blue-and-yellow macaws are known to "scream" for attention, and make other loud noises. Loud vocalizations, especially "flock calls", and destructive chewing are natural parts of their behavior and should be expected in captivity. Due to their large size, they also require plentiful space in which to fly around. According to World Parrot Trust, an enclosure for a blue-and-yellow macaw should, if possible, be at least 15 m (50 ft) in length. Captive macaws, kept with good diet, exercise, and veterinary care are known to have lived 60 or more years. People considering a macaw as a companion parrot must be aware of this and consider that the bird may outlive the owner.
+The blue-and-yellow macaw has been noted to blush its bare facial skin and fluff the feathers of its cheeks, head and nape when interacting with humans. This may be an expression of the parrot's emotional state.

+The red-and-green macaw (Ara chloropterus), also known as the green-winged macaw, is a large, mostly-red macaw of the genus  Ara.
+This is the largest of the genus Ara, widespread in the forests and woodlands of northern and central South America. However, in common with other macaws, in recent years there has been a marked decline in its numbers due to habitat loss and illegal capture for the parrot trade.
+
+
+== Description ==
+The green-winged macaw can be readily distinguished from the scarlet macaw. While the breast of both birds are bright red, the upper-wing covert feathers of the green-winged macaw is mostly green (as opposed to mostly yellow, or a strong mix of yellow and green in the scarlet macaw). In addition, the green-winged macaw has characteristic red lines around the eyes formed by rows of tiny feathers on the otherwise bare white skin patch; this is one of the biggest differences from a scarlet macaw to the casual viewer. Iridescent teal feathers are surrounded by red on the tail. If seen together, the green-winged macaw is clearly larger than the scarlet macaw as well.
+In terms of length, this species is second only in size to the hyacinth macaw, the largest of the macaws. The red-and-green macaw attains a total body length of 90 to 95 cm (35 to 37 in) in adults. Twelve adults were found to average 1,214 g (2.676 lb). A weight range of between 1,050 and 1,708 g (2.315 and 3.765 lb) has been reported. While its weight range is broadly similar to that of the hyacinth, the average weight of the red-and-green macaw is slightly surpassed by both the hyacinth and great green macaws, and amongst all living parrots additionally by the kakapo.
+
+
+== Behavior ==
+The green-winged macaw generally mates for life. The female typically lays two or three eggs in a nest made in a hole in a tree. The female incubates the eggs for about 28 days, and the chicks fledge from the nest about 90 days after hatching.
+
+
+== Population recovery ==
+Since 1999 a population has appeared on Trinidad. Although these might have escaped from captivity, it is also possible they have a wild origin.The historical range of this species is thought to have stretched southwards to include the Argentine provinces of Chaco, Corrientes, Formosa and Misiones. Hunting for meat, the pet trade and changes in land use are thought to have caused the species to be extirpated throughout its Argentine range by the 1960s. The species is listed as critically endangered in Argentina. In the mid-2010s birds were discovered to have colonised Iguazú National Park, and as of 2019 the species appears to have spread further into nearby Parque provincial Puerto Península.The species is furthermore the subject of a re-introduction programme to Iberá Provincial Reserve in the province of Corrientes by the World Parrot Trust, Aves Argentinas and Fundación CLT (Conservation Land Trust) (and perhaps BirdLife International), which is hoped may promote tourism to the area. Captive birds from Britain were imported in 2015 and the first pair of British birds was released in February 2019. Its wild population is estimated to be currently between 50,000 and 100,000 individuals.

+The scarlet macaw (Ara macao) is a large red, yellow, and blue Central and South American parrot, a member of a large group of Neotropical parrots called macaws. It is native to humid evergreen forests of the Neotropics. Its range extends from south-eastern Mexico to Peru, Ecuador, Colombia, Bolivia, Venezuela and Brazil in lowlands of 500 m (1,600 ft) (at least formerly) up to 1,000 m (3,300 ft), the Caribbean island of Trinidad, as well as the Pacific island of Coiba. Formerly, it ranged north to southern Tamaulipas. In some areas, it has suffered local extinction because of habitat destruction, or capture for the parrot trade, but in other areas, it remains fairly common. It is the national bird of Honduras. Like its relative the blue-and-yellow macaw, the scarlet macaw is a popular bird in aviculture as a result of its striking plumage.
+
+
+== Taxonomy ==
+The scarlet macaw was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Psittacus macao. The scarlet macaw is now placed in the genus Ara (Lacépède, 1799), one of 6 genera of Central and South American macaws.The two subspecies can be recognized by size and color detail in the feathers on the wings:
+A. m. macao (Linnaeus, 1758): South American scarlet macaw, the nominate subspecies. In the wings the medium and secondary coverts have green tip.
+A. m. cyanopterus Wiedenfeld, 1995: North Central American scarlet macaw. The Central American scarlet macaw is larger and has blue on its wings instead of green.
+
+
+=== Genetics ===
+In May 2013, it was announced that a team of scientists, led by Dr. Christopher M. Seabury and Dr. Ian Tizard of Texas A&M University had sequenced the complete genome of the scarlet macaw. Based on this genome, species-specific microsatellite genetic markers were developed to aid genetic studies throughout the range of the species.
+
+
+== Description ==
+It is about 81 centimeters (32 in) long, of which more than half is the pointed, graduated tail typical of all macaws, though the scarlet macaw has a larger percentage of tail than the other large macaws. The average weight is about 1 kilogram (2 lb 3 oz). The plumage is mostly scarlet, but the rump and tail-covert feathers are light blue, the greater upper wing coverts are yellow, the upper sides of the flight feathers of the wings are dark blue as are the ends of the tail feathers, and the undersides of the wing and tail flight feathers are dark red with metallic gold iridescence. Some individuals may have green in the wings.
+
+There is bare white skin around the eye and from there to the bill. Tiny white feathers are contained on the face patch. The upper mandible is mostly pale horn in color and the lower is black. Juveniles have dark eyes; adults have light yellow eyes.
+It is frequently confused with the slightly larger green-winged macaw, which has more distinct red lines in the face and no yellow in the wing.
+Scarlet macaws make very loud, high and sometimes low-pitched, throaty squawks, squeaks and screams designed to carry many kilometers to call for their groups.
+The scarlet macaw can live up to 75 or even 90 years in captivity, although a more typical lifespan is 40 to 50 years.
+
+
+== Behavior ==
+A typical sighting is of a single bird or a pair flying above the forest canopy, though in some areas flocks can be seen. They often gather at clay licks. Scarlet macaws communicate primarily through raucous honks; however, vocal communication is highly variable, and captive macaws are known to be adept mimics of human speech.
+
+
+=== Feeding ===
+Wild scarlet macaws feed on fruits, nuts, seeds, flowers and nectar.They also love to eat insects and larvae. They are seen feeding heavily on bugs, snails and foliage. Snails and bugs are great source of protein, as they need additional protein during breeding seasons.
+In Costa Rica's Central Pacific they have learned to feed on introduced Teak trees (Tectona grandis) and Almond Beach Trees (Terminalia sp). The local non-profit organizations have planted hundreds of those trees along the coastline from Tarcoles River basin to Esterillos Beach which had helped increase the population drastically. The combined efforts and the correct ecotourism has also an important role in the conservation of such majestic birds. Tour companies along the Tarcoles River and its mangroves have bet on the importance of birdwatching as an asset for the growth on its population.
+
+
+=== Breeding ===
+
+While comparatively docile at most times of the year, scarlet macaws may be formidably aggressive during periods of breeding. Scarlet macaws are monogamous birds, with individuals remaining with one partner throughout their lives. The hen lays two or three white eggs in a large tree cavity. The female incubates the eggs for about five weeks, and the chicks fledge from the nest about 90 days after hatching and leave their parents about a year later. Juveniles reach sexual maturity at five years of age.
+
+
+== Distribution and habitat ==
+The South American range is extensive and covers the  Amazon  forest, extending to Peru east of the Andes, to Bolivia. In Bolivia, it is very present in the Aquicuana Reserve, located in the Beni Department, near the city of Riberalta, the Capital of the Bolivian Amazon.
+
+In Central America, the range extends from extreme eastern and southern Mexico and Panama through Guatemala, El Salvador, Honduras and Belize, the island of Coiba and infrequently on the mainland of Panama, and in Costa Rica in isolated regions on the Pacific Coast; the Nicoya Peninsula the Carara National Park and Peninsula de Osa.
+The scarlet macaw has escaped or been deliberately released in to Florida, but there is no evidence that the population is breeding and may only persist due to continuing releases or escapes.Scarlet macaws inhabit humid lowland subtropical rain forests, open woodlands, river edges, and savannas.
+
+
+== Conservation status ==
+
+The habitat of scarlet macaws is also considered to have the greatest latitudinal range for any bird in the genus Ara, as the estimated maximum territorial range covers 6,700,000 km2. Nevertheless, the scarlet macaw's habitat is fragmented, and the bird is mostly confined to tiny populations scattered throughout its original range in Middle America. However, as they still occur in large numbers over most of their original range in South America, the species is classified by IUCN as least concern. Its wild population is currently estimated between 20,000 and 50,000 individuals.
+
+Commercial international trade in the species (including parts and derivatives) is prohibited by the bird's listing under CITES Appendix 1 due to predation for the pet and cage bird trade.  Both subspecies are listed by USFWS as endangered.
+
+
+== Aviculture ==
+The scarlet macaw is an early example of a parrot breeding in captivity. Captive breeding occurred in Northern Mexico at Paquime (also called Casas Grandes) and very likely Southwest New Mexico Mimbres Valley in the 11th century. Breeding pens, perches, bones, and eggshell fragments have been uncovered. The straightforward nature of scarlet macaw breeding and the value of their plumes in trade created a market for trade wherein the animals were used in religious rites north to the Colorado Plateau region.Today the scarlet macaw is found worldwide in captivity, but is best represented in captivity in the Americas. Captive techniques developed from the pet trade have positively affected wild populations: in areas with low macaws populations, the "extra" babies that typically die in the nest may be reared by humans hands and released into the wild to bolster the population, as has been done by the Tambopata Macaw Project. Their captive diet, egg incubation, assisted hatching, hand rearing, co-parenting, parent-rearing, fledgling, maturation, and breeding are well understood within the avicultural community (AFA Watchbird magazine).

+The red-fronted macaw (Ara rubrogenys) is a parrot endemic to a small semi-desert mountainous area of Bolivia. It is a critically endangered species; it has been successfully bred in captivity, and is available, if not common, as a pet. It is also sometimes known in the literature as Lafresnaye's macaw, named for the French ornithologist Frédéric de Lafresnaye, who was one of the first to describe the species.
+
+
+== Description ==
+The red-fronted macaw is 55–60 cm (21.5–23.5 in) long. It is mostly green, and has a red forehead, a red patch over the ears and bright red to orange edged under wing coverts. It has an area of pinkish skin around the eyes extending to the beak. It has red at the bend of wings and blue primary wing feathers.
+
+
+== Range and habitat ==
+The red-fronted macaw is native to a small mountainous area of south-central Bolivia situated about 200 km west of Santa Cruz, in the department of the same name, where the climate is medium altitude semi-desert. The natural vegetation consists mostly of cactus (large and small) and thorny trees and scrub. The climate is semi arid with cold nights and hot days. Rain comes in infrequent heavy storms. It is unusual in that it is the only macaw to inhabit such a climatic zone. Most macaws nest in holes in large trees, however here there are no very large trees in its range so it nests in vertical fissures in cliff faces. The bird has been captured for the pet trade in the past and killed by local farmers because it raids their crops.

+The great argus (Argusianus argus) is a species of pheasant from Southeast Asia.
+It is not to be confused with the two species of closely related crested argus, genus Rheinardia.
+
+
+== Taxonomy ==
+ 
+Carl Linnaeus gave the great argus its specific name (from which its common name and genus name are derived) because of the intricate eye-like patterns on its wings, in reference to Argus, a hundred-eyed giant in Greek mythology. There are two subspecies recognized: Nominate argus of the Malay peninsula and Sumatra, and A. a. grayi of Borneo. William Beebe considered the two races to be distinct species, but they have since been lumped.
+
+
+=== Double-banded argus ===
+The double-banded argus (Argusianus bipunctatus), known only from a portion of a single primary flight feather, was long considered a potential second species. It was described in 1871 from this feather piece, found in a millinery shipment imported to London. Its origin was hypothesized to be from Java, Indonesia or Tioman Island of Malaysia, because of the great argus's absence from these locations. Parkes (1992) rejected the double-banded argus's validity and argued that it almost certainly represents a mutant form of the great argus. The IUCN, following the precautionary principle, listed this taxon as extinct until 2012. It was removed from the IUCN Red list because the IOC had removed this species from its list of valid bird taxa in 2011. While the feather is indeed quite distinct, it represents a fairly simple divergence: The entirely asymmetrically-patterned vanes are instead near-symmetrical, and both bear the darker brown shaftward area with dense whitish speckles. The shaft is thinner than usual and the feather would probably not have been useful for flight.Nothing similar has come to notice ever since, and as the feather piece is not a composite of two feather halves glued together but an apparently natural specimen, a hoax or fake can be ruled out. Despite all conjecture that has been built around the feather piece, all that can be said is that at some time around 1870, an argus pheasant which bore at least one such feather was shot in an unknown location. Even if this individual was one of the last remnants of a now-extinct population, it is unlikely that only a single feather would have been taken from an unusual specimen of a well-known, often-hunted, and conspicuous bird, and that this single feather would have then been bundled into a shipment of normal great argus feathers. The feather is now housed in the Natural History Museum in London.
+
+
+== Names ==
+Malay language: Kuang raya "great pheasant" 
+
+
+== Description ==
+
+The great argus is a brown-plumaged pheasant with a blue head and neck, rufous red upper breast, black hair-like feathers on the crown and nape, and red legs.
+Unusual among Galliformes, the great argus has no uropygial gland.
+
+
+=== Male and female plumage ===
+The male is one of the largest of all pheasants, measuring 160–200 cm (63–79 in) in total length, including a tail of 105–143 cm (41–56 in), and weighing 2.04–2.72 kg (4.5–6.0 lb). Males have very long tail feathers and huge, broad and greatly elongated secondary wing feathers decorated with large eyespots. Young males develop their adult plumage in their third year.Females are smaller and duller than males, with shorter tails and fewer eyespots. They measure 72–76 cm (28–30 in) in total length, including a tail of 30–36 cm (12–14 in), and weighs 1.59–1.7 kg (3.5–3.7 lb).
+
+
+== Behaviour ==
+
+
+=== Diet ===
+It feeds on the forest floor in early morning and evening.
+
+
+=== Mating dance ===
+
+The male clears an open spot in the forest and prepares a dancing ground. He announces himself with loud calls to attract females, then he dances before her with his wings spread into two enormous fans, revealing hundreds of "eyes" while his real eyes are hidden behind it, staring at her.
+
+
+=== Breeding ===
+Despite displays similar to polygamous birds and though the great argus was thought to be polygamous in the wild, it has been discovered that it is actually monogamous. The hen lays only two eggs.
+
+
+== Distribution and habitat ==
+The great argus is native to the jungles of Borneo, Sumatra and the Malay Peninsula in southeast Asia.
+

+The Colombian spider monkey (Ateles fusciceps rufiventris) is a subspecies of the Black-headed spider monkey, a type of New World monkey, found in Colombia and Panama.  Some authorities, such as Froelich (1991), Collins and Dubach (2001) and Nieves (2005), do not recognize the Black-headed spider monkey as a distinct species and so treat the Colombian spider monkey as a subspecies of Geoffroy's spider monkey.The Colombian spider monkey lives in dry forests, humid forests and cloud forests, and can live up to 2,000 to 2,500 metres (6,600 to 8,200 ft) above sea level. It is entirely black with some white on its chin while the Brown-headed spider monkey (A. f. fusciceps) has a black or brown body and a brown head.The spider monkey has a black body and long limbs with thumb-less hands.  It has a prehensile and extremely flexible tail, which acts as an extra limb.  The tail has a hairless patch on the tip that is used for grip.  This hairless patch is unique in its markings, just like the human fingerprint.  Colombian spider monkeys can weigh up to 9.1 kg (20 pounds).  Fruit makes up eighty percent of the spider monkey's diet, which also includes leaves, nuts, seeds, bark, insects, and flowers. Spider monkeys contribute to the dispersion of undigested seeds from the fruits they eat. This monkey lives approximately 24 years.
+Spider monkeys are found in social groups of up to 30 individuals; however, they are usually broken up into smaller foraging groups of 3-4 individuals.  They move and climb through the forest by hand over hand (brachiation) motion.

+The black-headed spider monkey (Ateles fusciceps) is a type of New World monkey, from Central and South America. It is found in Colombia, Ecuador, and Panama. Although primatologists such as Colin Groves (1989) follow Kellogg and Goldman (1944) in treating A. fusciceps as a separate species, other authors, including Froelich (1991), Collins and Dubach (2001) and Nieves (2005) treat it as a subspecies of Geoffroy's spider monkey.The two subspecies are:
+Ateles fusciceps fusciceps - northwestern Ecuador.
+Ateles fusciceps rufiventris - southwest Colombia to eastern Panama.A. f. fusciceps lives in tropical and subtropical humid forests between 100 and 1,700 metres (330 and 5,580 ft) above sea level.  It lives in population densities of 1.2 monkeys per square kilometer. A. f. rufiventris lives in dry forests, humid forests and cloud forests, and can live up to 2,000 to 2,500 metres (6,600 to 8,200 ft) above sea level.A. f. fusciceps has a black or brown body and a brown head.  A. f. rufiventris is entirely black with some white on its chin.  The black-headed spider monkey is one of the larger New World monkeys. The head and body length, excluding tail, typically ranges between 39.3 and 53.8 cm (15.5 and 21.2 in). The prehensile tail is between 71.0 and 85.5 cm (28.0 and 33.7 in). On average, males weigh 8.89 kilograms (19.6 lb) and females weigh 8.8 kilograms (19 lb).  The brain weighs 114.7 g (4.05 oz).The black-headed spider monkey is arboreal and diurnal. It moves by climbing and brachiation. When mating, females may consort with a male for up to three days, or else mate with several males.  Mating occurs with the male and female face to face, and can last for five to 10 minutes.  The gestation period is between 226 and 232 days. The infant rides on its mother's back for 16 weeks, and is weaned at 20 months. Females attain sexual maturity at 51 months; males at 56 months. Females give birth every three years.The black-headed spider monkey is considered to be endangered by the International Union for Conservation of Nature (IUCN) due to an estimated population loss of more than 50% over 45 years (2018-2063), from hunting and human encroachment on its range of habitation.Captive black-headed spider monkeys have been known to live more than 24 years.

+The grey crowned crane (Balearica regulorum), also known as the African crowned crane, golden crested crane, golden crowned crane, East African crane, East African crowned crane, African crane, Eastern crowned crane, Kavirondo crane, South African crane and crested crane, is a bird in the crane family, Gruidae. It is found in eastern and southern Africa, and is the national bird of Uganda.
+
+
+== Taxonomy ==
+The grey crowned crane is closely related to the black crowned crane, and the two species have sometimes been treated as the same species. The two are separable on the basis of genetic evidence, calls, plumage and bare parts, and all authorities treat them as different species today.There are two subspecies. The East African B. r. gibbericeps (crested crane) occurs in the east of the Democratic Republic of the Congo and in Uganda, of which it is the national bird represented in its national flag, and Kenya to eastern South Africa. It has a larger area of bare red facial skin above the white patch than the smaller nominate species, B. r. regulorum (South African crowned crane), which breeds from Angola south to South Africa.
+
+
+== Description ==
+
+The grey crowned crane is about 1 m (3.3 ft) tall, weighs 3.5 kg (7.7 lbs), and has a wingspan of 2 m (6.5 ft). Its body plumage is mainly grey. The wings are predominantly white, but contain feathers with a range of colours, with a distinctive black patch at the very top. The head has a crown of stiff golden feathers. The sides of the face are white, and there is a bright red inflatable throat pouch. The bill is relatively short and grey, and the legs are black. They have long legs for wading through the grasses. The feet are large, yet slender, adapted for balance rather than defence or grasping. The sexes are similar, although males tend to be slightly larger. Young birds are greyer than adults, with a feathered buff face.
+This species and the black crowned crane are the only cranes that can roost in trees, because of a long hind toe that can grasp branches. This trait is assumed to be an ancestral trait among the cranes, which has been lost in the other subfamily. Crowned cranes also lack a coiled trachea and have loose plumage compared to the other cranes.
+
+
+== Distribution and habitat ==
+
+The grey crowned crane occurs in dry savannah in Sub-Saharan Africa, although it nests in somewhat wetter habitats. They can also be found in marshes, cultivated lands and grassy flatlands near rivers and lakes in Uganda and Kenya and as far south as South Africa. This animal does not have set migration patterns, and birds nearer the tropics are typically sedentary. Birds in more arid areas, particularly Namibia, make localised seasonal movements during drier periods.
+
+
+== Behaviour ==
+The grey crowned crane has a breeding display involving dancing, bowing, and jumping. It has a booming call which involves inflation of the red gular sac. It also makes a honking sound quite different from the trumpeting of other crane species. Both sexes dance, and immature birds join the adults. Dancing is an integral part of courtship, but also may be done at any time of the year.
+Flocks of 30–150 birds are not uncommon.
+
+
+=== Diet and feeding ===
+These cranes are omnivores, eating plants, seeds, grain, insects, frogs, worms, snakes, small fish and the eggs of aquatic animals. Stamping their feet as they walk, they flush out insects which are quickly caught and eaten. The birds also associate with grazing herbivores, benefiting from the ability to grab prey items disturbed by antelopes and gazelles. They spend their entire day looking for food. At night, the crowned crane spends its time in the trees sleeping and resting.
+
+
+=== Breeding ===
+
+Grey crowned cranes time their breeding season around the rains, although the effect varies geographically. In East Africa the species breeds year-round, but most frequently during the drier periods, whereas in Southern Africa the breeding season is timed to coincide with the rains. During the breeding season, pairs of cranes construct a large nest; a platform of grass and other plants in tall wetland vegetation. 
+
+The grey crowned crane lays a clutch of 2-5 glossy, dirty-white eggs, which are incubated by both sexes for 28–31 days. Chicks are precocial, can run as soon as they hatch, and fledge in 56–100 days. Once they are fully grown and independent, chicks of different sexes will separate from their parents to start their own family. Grey crowned cranes have been seen to congregate in large numbers in a ceremony akin to a wedding when two chicks are being married off. The new couple dance for a while before flying off together to start a new family.
+
+
+== Relationship with humans ==
+
+
+=== Status and conservation ===
+Although the grey crowned crane remains common over some of its range, it faces threats to its habitat due to drainage, overgrazing, and pesticide pollution. Their global population is estimated to be between 58,000 and 77,000 individuals. In 2012 it was uplisted from vulnerable to endangered by the IUCN.
+
+

+The grey crowned crane (Balearica regulorum), also known as the African crowned crane, golden crested crane, golden crowned crane, East African crane, East African crowned crane, African crane, Eastern crowned crane, Kavirondo crane, South African crane and crested crane, is a bird in the crane family, Gruidae. It is found in eastern and southern Africa, and is the national bird of Uganda.
+
+
+== Taxonomy ==
+The grey crowned crane is closely related to the black crowned crane, and the two species have sometimes been treated as the same species. The two are separable on the basis of genetic evidence, calls, plumage and bare parts, and all authorities treat them as different species today.There are two subspecies. The East African B. r. gibbericeps (crested crane) occurs in the east of the Democratic Republic of the Congo and in Uganda, of which it is the national bird represented in its national flag, and Kenya to eastern South Africa. It has a larger area of bare red facial skin above the white patch than the smaller nominate species, B. r. regulorum (South African crowned crane), which breeds from Angola south to South Africa.
+
+
+== Description ==
+
+The grey crowned crane is about 1 m (3.3 ft) tall, weighs 3.5 kg (7.7 lbs), and has a wingspan of 2 m (6.5 ft). Its body plumage is mainly grey. The wings are predominantly white, but contain feathers with a range of colours, with a distinctive black patch at the very top. The head has a crown of stiff golden feathers. The sides of the face are white, and there is a bright red inflatable throat pouch. The bill is relatively short and grey, and the legs are black. They have long legs for wading through the grasses. The feet are large, yet slender, adapted for balance rather than defence or grasping. The sexes are similar, although males tend to be slightly larger. Young birds are greyer than adults, with a feathered buff face.
+This species and the black crowned crane are the only cranes that can roost in trees, because of a long hind toe that can grasp branches. This trait is assumed to be an ancestral trait among the cranes, which has been lost in the other subfamily. Crowned cranes also lack a coiled trachea and have loose plumage compared to the other cranes.
+
+
+== Distribution and habitat ==
+
+The grey crowned crane occurs in dry savannah in Sub-Saharan Africa, although it nests in somewhat wetter habitats. They can also be found in marshes, cultivated lands and grassy flatlands near rivers and lakes in Uganda and Kenya and as far south as South Africa. This animal does not have set migration patterns, and birds nearer the tropics are typically sedentary. Birds in more arid areas, particularly Namibia, make localised seasonal movements during drier periods.
+
+
+== Behaviour ==
+The grey crowned crane has a breeding display involving dancing, bowing, and jumping. It has a booming call which involves inflation of the red gular sac. It also makes a honking sound quite different from the trumpeting of other crane species. Both sexes dance, and immature birds join the adults. Dancing is an integral part of courtship, but also may be done at any time of the year.
+Flocks of 30–150 birds are not uncommon.
+
+
+=== Diet and feeding ===
+These cranes are omnivores, eating plants, seeds, grain, insects, frogs, worms, snakes, small fish and the eggs of aquatic animals. Stamping their feet as they walk, they flush out insects which are quickly caught and eaten. The birds also associate with grazing herbivores, benefiting from the ability to grab prey items disturbed by antelopes and gazelles. They spend their entire day looking for food. At night, the crowned crane spends its time in the trees sleeping and resting.
+
+
+=== Breeding ===
+
+Grey crowned cranes time their breeding season around the rains, although the effect varies geographically. In East Africa the species breeds year-round, but most frequently during the drier periods, whereas in Southern Africa the breeding season is timed to coincide with the rains. During the breeding season, pairs of cranes construct a large nest; a platform of grass and other plants in tall wetland vegetation. 
+
+The grey crowned crane lays a clutch of 2-5 glossy, dirty-white eggs, which are incubated by both sexes for 28–31 days. Chicks are precocial, can run as soon as they hatch, and fledge in 56–100 days. Once they are fully grown and independent, chicks of different sexes will separate from their parents to start their own family. Grey crowned cranes have been seen to congregate in large numbers in a ceremony akin to a wedding when two chicks are being married off. The new couple dance for a while before flying off together to start a new family.
+
+
+== Relationship with humans ==
+
+
+=== Status and conservation ===
+Although the grey crowned crane remains common over some of its range, it faces threats to its habitat due to drainage, overgrazing, and pesticide pollution. Their global population is estimated to be between 58,000 and 77,000 individuals. In 2012 it was uplisted from vulnerable to endangered by the IUCN.

+The American bison (Bison bison) is a species of bison native to North America. Sometimes colloquially referred to as American buffalo or simply buffalo (a different clade of bovine), it is one of two extant species of bison, alongside  the European bison. Its historical range, by 9000 BC, is described as the great bison belt, a tract of rich grassland that ran from Alaska to the Gulf of Mexico, east to the Atlantic Seaboard (nearly to the Atlantic tidewater in some areas) as far north as New York, south to Georgia and, according to some sources, further south to Florida, with sightings in North Carolina near Buffalo Ford on the Catawba River as late as 1750. Once roaming in vast herds, the species nearly became extinct by a combination of commercial hunting and slaughter in the 19th century and introduction of bovine diseases from domestic cattle.  With a population in excess of 60 million in the late 18th century, the species was culled down to just 541 animals by 1889. Recovery efforts expanded in the mid-20th century, with a resurgence to roughly 31,000 wild bison as of March 2019. For many years, the population was primarily found in a few national parks and reserves. Through multiple reintroductions, the species now freely roams wild in several regions in the United States, Canada, and Mexico, with it also being introduced to Yakutia in Russia.Two subspecies or ecotypes have been described: the plains bison (B. b. bison), smaller in size and with a more rounded hump, and the wood bison (B. b. athabascae)—the larger of the two and having a taller, square hump. Furthermore, the plains bison has been suggested to consist of a northern plains (B. b. montanae) and a southern plains (B. b. bison) subspecies, bringing the total to three. However, this is generally not supported. The wood bison is one of the largest wild species of extant bovid in the world, surpassed only by the Asian gaur. Among extant land animals in North America, the bison is the heaviest and the longest, and the second tallest after the moose.
+Spanning back many millennia, Native American tribes have had cultural and spiritual connections to the American bison. It is the national mammal of the United States of America.
+
+
+== Etymology ==
+
+There are two living species of bison: the American bison and the European bison; and two types of buffalo: the African buffalo, native to Africa, and the water buffalo, native to Asia. Samuel de Champlain applied the term buffalo (buffles in French) to the bison in 1616 (published 1619), after seeing skins and a drawing shown to him by members of the Nipissing First Nation, who said they travelled forty days (from east of Lake Huron) to trade with another nation who hunted the animals. In English usage, the term buffalo dates to 1625 in North America, when the term was first recorded for the American mammal. The word buffalo is derived from the French “bœuf,” a name given to bison when French fur trappers working in the US in the early 1600s saw the animals. The word bœuf came from what the French knew as true buffalo, animals living in Africa and Asia. The term bison was first recorded in 1774, and is the correct scientific terminology.
+In Plains Indian languages in general, male and female bison are distinguished, with each having a different designation rather than there being a single generic word covering both sexes. Thus:
+
+in Arapaho: bii (bison cow), henéécee (bison bull)
+in Lakota: pté (bison cow), tȟatȟáŋka (bison bull)Such a distinction is not a general feature of the language (for example, Arapaho possesses gender-neutral terms for other large mammals such as elk, mule deer, etc.), and so presumably is due to the special significance of the bison in Plains Indian life and culture.
+
+
+== Description ==
+
+A bison has a shaggy, long, dark-brown winter coat, and a lighter-weight, lighter-brown summer coat. Male bison are significantly larger and heavier than females. Plains bison are often in the smaller range of sizes, and wood bison in the larger range. Head-rump lengths at maximum up to 3.5 m (11 ft 6 in) for males and 2.85 m (9 ft 4 in) for females long and the tail adding 30 to 95 cm (1 ft 0 in to 3 ft 1 in). Heights at withers in the species can reach up to 186 to 201 cm (6 ft 1 in to 6 ft 7 in) for B. b. bison and B. b. athabascae respectively. Typically weights can range from 318 to 1,179 kg (701 to 2,599 lb), 460 to 988 kg (1,014 to 2,178 lb) with medians of 730 to 792.5 kg (1,609 to 1,747 lb) (B.b. bison) and 943.6 kg (2,080 lb) (B.b.athabascae) in males, and 360 to 640 kg (790 to 1,410 lb) with medians of 450 to 497.6 kg (992 to 1,097 lb) in females, although the lowest weights probably representing typical weight around the age of sexual maturity at 2 to 3 years of age. The heaviest wild bull for B.b.bison ever recorded weighed 1,270 kg (2,800 lb) while there had been bulls estimated to be 1,400 kg (3,000 lb). B.b.athabascae is significantly larger and heavier on average than B.b.bison while the number of recorded samples for the former was limited after the rediscovery of a relatively pure herd. Elk Island National Park, which has wild populations of both wood and plains bison, has recorded maximum weights for bull bison of 1186 kg (plains) and 1099 kg (wood), but noted that 3/4 of all bison over 1000 kg were wood bison. When raised in captivity and farmed for meat, the bison can grow unnaturally heavy and the largest semidomestic bison weighed 1,724 kg (3,801 lb). The heads and forequarters are massive, and both sexes have short, curved horns that can grow up to 60 cm (2 ft)  long with 90 cm (3 ft) to 124 cm (4 ft) width, which they use in fighting for status within the herd and for defense.
+Bison are herbivores, grazing on the grasses and sedges of the North American prairies. Their daily schedule involves two-hour periods of grazing, resting, and cud chewing, then moving to a new location to graze again. Sexually mature young bulls may try to start mating with cows by the age of two or three years, but if more mature bulls are present, they may not be able to compete until they reach five years of age.
+For the first two months of life, calves are lighter in color than mature bison. One very rare condition is the white buffalo, in which the calf turns entirely white.
+
+
+== Evolution ==
+Bison are members of the tribe Bovini. Genetic evidence from nuclear DNA indicates that the closest living relatives of bison are yaks, with bison being nested within the genus Bos, rendering Bos without including bison paraphyletic. While nuclear DNA indicates that the two living bison species are each others closest living relatives, the mitochondrial DNA of European bison is more closely related to that of domestic cattle and aurochs, which is either suggested to be the result of incomplete lineage sorting or ancient introgression. Bison first appeared in Asia during the Early Pleistocene, around 2.6 million years ago. Bison only arrived in North America 195,000 to 135,000 years ago, during the late Middle Pleistocene, descending from the widespread Siberian steppe bison (Bison priscus), which had migrated through Beringia. Following its first appearance in North America, the bison rapidly differentiated into new species such as the largest of all bison, the long-horned Bison latifrons as well as Bison antiquus. The first appearance of bison in North America is considered to define the regional Rancholabrean faunal stage, due to its major impact on the ecology of the continent. Modern American bison are thought to have evolved from B. antiquus during the Late Pleistocene-Holocene transition via the intermediate form Bison occidentalis.
+
+
+=== Differences from European bison ===
+
+Although they are superficially similar, the American and European bison exhibit a number of physical and behavioral differences. Adult American bison are slightly heavier on average because of their less rangy build, and have shorter legs, which render them slightly shorter at the shoulder. American bison tend to graze more, and browse less than their European relatives, because their necks are set differently. Compared to the nose of the American bison, that of the European species is set farther forward than the forehead when the neck is in a neutral position. The body of the American bison is hairier, though its tail has less hair than that of the European bison. The horns of the European bison point forward through the plane of its face, making it more adept at fighting through the interlocking of horns in the same manner as domestic cattle, unlike the American bison which favors charging. American bison are more easily tamed than the European, and breed more readily with domestic cattle.
+
+
+=== Crossbreeding with cattle ===
+During the population bottleneck, after the great slaughter of American bison during the 1800s, the number of bison remaining alive in North America declined to as low as 541. During that period, a handful of ranchers gathered remnants of the existing herds to save the species from extinction. These ranchers bred some of the bison with cattle in an effort to produce "cattalo" or "beefalo". Accidental crossings were also known to occur. Generally, male domestic bulls were crossed with bison cows, producing offspring of which only the females were fertile. The crossbred animals did not demonstrate any form of hybrid vigor, so the practice was abandoned. The proportion of cattle DNA that has been measured in introgressed individuals and bison herds today is typically quite low, ranging from 0.56 to 1.8%. In the United States, many ranchers are now using DNA testing to cull the residual cattle genetics from their bison herds. The U.S. National Bison Association has adopted a code of ethics which prohibits its members from deliberately crossbreeding bison with any other species.
+
+
+== Range and population ==
+
+Despite being the closest relatives of domestic cattle native to North America, bison were never domesticated by Native Americans. Later attempts of domestication by Europeans prior to the 20th century met with limited success. Bison were described as having a "wild and ungovernable temper"; they can jump close to 1.8 m (6 ft) vertically, and run 55–70 km/h (35–45 mph) when agitated. This agility and speed, combined with their great size and weight, makes bison herds difficult to confine, as they can easily escape or destroy most fencing systems, including most razor wire. The most successful systems involve large, 6-metre (20 ft) fences made from welded steel I beams sunk at least 1.8 m (6 ft) into concrete. These fencing systems, while expensive, require very little maintenance. Furthermore, making the fence sections overlap so the grassy areas beyond are not visible prevents the bison from trying to get to new range.
+Population estimates in 2010 ranged from 400,000 to 500,000, with approximately 20,500 animals in 62 conservation herds and the remainder in approximately 6,400 commercial herds. According to the IUCN, roughly 15,000 bison are considered wild, free-range bison not primarily confined by fencing.
+The Nature Conservancy (TNC) has reintroduced bison to over a dozen nature preserves around the United States. In October 2016, TNC established its easternmost bison herd in the country, at Kankakee Sands nature preserve in Morocco, Newton County, Indiana.  In 2014, U.S Tribes and Canadian First Nations signed a treaty to help with the restoration of bison, the first to be signed in nearly 150 years.
+
+
+=== Habitat and trails ===
+
+American bison live in river valleys, and on prairies and plains.  Typical habitat is open or semiopen grasslands, as well as sagebrush, semiarid lands, and scrublands. Some lightly wooded areas are also known historically to have supported bison.  Bison also graze in hilly or mountainous areas where the slopes are not steep.  Though not particularly known as high-altitude animals, bison in the Yellowstone Park bison herd are frequently found at elevations above 2,400 m (8,000 ft) and the Henry Mountains bison herd is found on the plains around the Henry Mountains, Utah, as well as in mountain valleys of the Henry Mountains to an altitude of 3,000 m (10,000 ft). Reintroduced plains bison in Banff National Park have been observed to roam mountainous areas including high ridges and steep drainages, and archaeological finds indicate some bison historically may have spent their lives within mountains while others may have migrated in and out of mountains.
+Those in Yukon, Canada, typically summer in alpine plateaus above treeline. The first thoroughfares of North America, except for the time-obliterated paths of mastodon or muskox and the routes of the mound builders, were the traces made by bison and deer in seasonal migration and between feeding grounds and salt licks. Many of these routes, hammered by countless hoofs instinctively following watersheds and the crests of ridges in avoidance of lower places' summer muck and winter snowdrifts, were followed by the aboriginal North Americans as courses to hunting grounds and as warriors' paths. They were invaluable to explorers and were adopted by pioneers.
+Bison traces were characteristically north and south, but several key east–west trails were used later as railways. Some of these include the Cumberland Gap through the Blue Ridge Mountains to upper Kentucky. A heavily used trace crossed the Ohio River at the Falls of the Ohio and ran west, crossing the Wabash River near Vincennes, Indiana. In Senator Thomas Hart Benton's phrase saluting these sagacious path-makers, the bison paved the way for the railroads to the Pacific.
+
+
+=== Mexico ===
+
+The southern extent of the historic range of the American bison includes northern Mexico and adjoining areas in the United States as documented by archeological records and historical accounts from Mexican archives from 700 CE to the 19th century. The Janos-Hidalgo bison herd has ranged between Chihuahua, Mexico, and New Mexico, United States, since at least the 1920s. The persistence of this herd suggests that habitat for bison is suitable in northern Mexico. In 2009, genetically pure bison were reintroduced to the Janos Biosphere Reserve in northern Chihuahua adding to the Mexican bison population. In 2020, the second herd was formed in Maderas del Carmen. A private reserve named Jagüey de Ferniza has kept bisons since before the above-mentioned reintroductions in Coahuila.
+
+
+=== Introductions to Siberia ===
+
+Since 2006, an outherd of wood bison sent from Alberta's Elk Island National Park was established in Yakutia, Russia as a practice of pleistocene rewilding; wood bison are the most closely related to the extinct bison species. The bison are adapting well to the cold climate, and Yakutia's Red List officially registered the species in 2019; a second herd was formed in 2020.In Pleistocene Park, there are also 24 plains bison as wood bison could not be acquired.
+
+
+== Behavior and ecology ==
+
+Bison are migratory and herd migrations can be directional as well as altitudinal in some areas. Bison have usual daily movements between foraging sites during the summer. In the Hayden Valley, Wyoming, bison have been recorded traveling, on average, 3 km (2 mi) per day. The summer ranges of bison appear to be influenced by seasonal vegetation changes, interspersion and size of foraging sites, the rut, and the number of biting insects. The size of preserve and availability of water may also be a factor. Bison are largely grazers, eating primarily grasses and sedges. On shortgrass pasture, bison predominately consume warm-season grasses. On mixed prairie, cool-season grasses, including some sedges, apparently compose 79–96% of their diet. In montane and northern areas, sedges are selected throughout the year. Bison also drink water or consume snow on a daily basis.
+
+
+=== Social behavior and reproduction ===
+
+Female bison live in maternal herds which include other females and their offspring. Male offspring leave their maternal herd when around three years old and either live alone or join other males in bachelor herds. Male and female herds usually do not mingle until the breeding season, which can occur from July through September. However, female herds may also contain a few older males. During the breeding season, dominant bulls maintain a small harem of females for mating. Individual bulls "tend" cows until allowed to mate, by following them around and chasing away rival males. The tending bull shields the female's vision with his body so she will not see any other challenging males. A challenging bull may bellow or roar to get a female's attention and the tending bull has to bellow/roar back. The most dominant bulls mate in the first 2–3 weeks of the season. More subordinate bulls mate with any remaining estrous cow that has not mated yet. Male bison play no part in raising the young.
+
+Bison herds have dominance hierarchies that exist for both males and females. A bison's dominance is related to its birth date. Bison born earlier in the breeding season are more likely to be larger and more dominant as adults. Thus, bison are able to pass on their dominance to their offspring as dominant bison breed earlier in the season. In addition to dominance, the older bison of a generation also have a higher fertility rate than the younger ones.Bison mate in August and September; gestation is 285 days. A single reddish-brown calf nurses until the next calf is born. If the cow is not pregnant, a calf will nurse for 18 months. Cows nurse their calves for at least 7 or 8 months, but most calves seem to be weaned before the end of their first year. At three years of age, bison cows are mature enough to produce a calf. The birthing period for bison in boreal biomes is protracted compared to that of other northern ungulates, such as moose and caribou.Bison have a life expectancy around 15 years in the wild and up to 25 years in captivity. However, males and females from a hunted population also subject to wolf predation in northern Canada have been reported to live to 22 and 25 years of age, respectively.Bison have been observed to display homosexual behaviors, males much more so than females. In the case of males, it is unlikely to be related to dominance, but rather to social bonding or gaining sexual experience.
+
+
+=== Horning ===
+Bison mate in late spring and summer in more open plain areas. During fall and winter, bison tend to gather in more wooded areas. During this time, bison partake in horning behaviors. They rub their horns against trees, young saplings, and even utility poles. Aromatic trees like cedars and pine seem to be preferred. Horning appears to be associated with insect defense, as it occurs most often in the fall when the insect population is at its highest. Cedar and pines emit an aroma after bison horn them and this seems to be used as a deterrent for insects.
+
+
+=== Wallowing behavior ===
+ 
+A bison wallow is a shallow depression in the soil, which bison use either wet or dry. Bison roll in these depressions, covering themselves with dust or mud. Past and current hypotheses to explain the purpose of wallowing include grooming associated with shedding, male-male interaction (typically rutting), social behavior for group cohesion, play, relief from skin irritation due to biting insects, reduction of ectoparasite (tick and lice) load, and thermoregulation. Bison wallowing has important ecosystem engineering effects and enhances plant and animal diversity on prairies.
+
+
+=== Predation ===
+
+While often secure from predation because of their size and strength, in some areas, vulnerable individuals are regularly preyed upon by wolves. Wolf predation typically peaks in late winter, when elk migrates south and bison are distressed with heavy snows and shortages of food sources, with attacks usually being concentrated on weakened and injured cows and calves. Wolves more actively target herds with calves than those without. The length of a predation episode varies, ranging from a few minutes to over nine hours. Bison display five apparent defense strategies in protecting calves from wolves: running to a cow; running to a herd; running to the nearest bull; running in the front or center of a stampeding herd; entering water bodies, such as lakes or rivers. When fleeing wolves in open areas, cows with young calves take the lead, while bulls take to the rear of the herds, to guard the cows' escape. Bison typically ignore wolves not displaying hunting behavior. Wolf packs specializing in bison tend to have more males, because their larger size than females allows them to wrestle prey to the ground more effectively. Healthy, mature bulls in herds rarely fall prey.
+Grizzly bears are known to feed on carcass and may steal wolves' kills. While grizzlies can also pose a threat to calves and sometimes old, injured, or sick adult bison, direct killing of non-calves is rare even when targeting lone and injured young individuals; attacking healthy bison is risky for bears, who can be killed instead.
+
+
+=== Dangers to humans ===
+Bison are among the most dangerous animals encountered by visitors to the various North American national parks and will attack humans if provoked. They appear slow because of their lethargic movements, but can easily outrun humans; bison have been observed running as fast as 65 to 70 km/h (40 to 45 mph) for 8 km (5 mi). Bison may approach people for curiosity, and close encounters including to touch the animals can be dangerous, and gunshots do not startle them.
+
+Between 1980 and 1999, more than three times as many people in Yellowstone National Park were injured by bison than by bears. During this period, bison charged and injured 79 people, with injuries ranging from goring puncture wounds and broken bones to bruises and abrasions. Bears injured 24 people during the same time. Three people died from the injuries inflicted—one person by bison in 1983, and two people by bears in 1984 and 1986.
+
+
+== Hunting ==
+
+Buffalo hunting, i.e. hunting of the American bison, was an activity fundamental to the Indigenous peoples of the Great Plains. This activity was later adopted by American professional hunters, as well as by the U.S. government, in an effort to sabotage the central resource of some American Indian Nations during the later portions of the American Indian Wars, leading to the near-extinction of the species around 1890. For many tribes the buffalo was an integral part of life—something guaranteed to them by the Creator. In fact, for some Plains indigenous peoples, bison are known as the first people. The concept of species extinction was foreign to many tribes. Thus, when the U.S. government began to massacre the buffalo, it was particularly harrowing to the Indigenous people. As Crow chief Plenty Coups described it: "When the buffalo went away the hearts of my people fell to the ground, and they could not lift them up again. After this nothing happened. There was little singing anywhere." Spiritual loss was rampant; bison were an integral part of traditional tribal societies and they would frequently take part in ceremonies for each bison they killed to honor its sacrifice. In order to boost morale during this time, Sioux and other tribes took part in the Ghost Dance, which consisted of hundreds of people dancing until 100 persons were lying unconscious.Today, many conservation measures have been taken by Native Americans with the Inter Tribal Bison Council being one of the most significant. It was formed in 1990, composed of 56 tribes in 19 states. These tribes represent a collective herd of more than 15,000 bison and focus on reestablishing herds on tribal lands in order to promote culture, revitalize spiritual solidarity, and restore the ecosystem. Some Inter Tribal Bison Council members argue that the bison's economic value is one of the main factors driving its resurgence. Bison serve as a low cost substitute for cattle, and can withstand the winters in the Plains region far easier than cattle.

+
+
+=== As livestock ===
+Bison are increasingly raised for meat, hide, wool, and dairy products. The majority of American bison in the world are raised for human consumption or fur clothing. Bison meat is generally considered to taste very similar to beef, but is lower in fat and cholesterol, yet higher in protein than beef, which has led to the development of beefalo, a fertile hybrid of bison and domestic cattle. In 2005, about 35,000 bison were processed for meat in the U.S., with the National Bison Association and USDA providing a "Certified American Buffalo" program with birth-to-consumer tracking of bison via RFID ear tags. A market even exists for kosher bison meat; these bison are slaughtered at one of the few kosher mammal slaughterhouses in the U.S., and the meat is then distributed nationwide.
+Bison are found in publicly and privately held herds. Custer State Park in South Dakota is home to 1,500 bison, one of the largest publicly held herds in the world, but some question the genetic purity of the animals. Wildlife officials believe that free roaming and genetically pure herds on public lands in North America can be found only in: the Yellowstone Park bison herd; the Henry Mountains bison herd at the Book Cliffs and Henry Mountains in Utah; at Wind Cave National Park in South Dakota; Fort Peck Indian Reservation in Montana; Mackenzie Bison Sanctuary in the Northwest Territories; Elk Island National Park and Wood Buffalo National Park in Alberta; and Prince Albert National Park in Saskatchewan. Another population, the Antelope Island bison herd on Antelope Island in Utah, consisting of 550 to 700 bison, is also one of the largest and oldest public herds in the United States, but the bison in that herd are considered to be only semifree roaming, since they are confined to the Antelope Island. In addition, recent genetic studies indicate that, like most bison herds, the Antelope Island bison herd has a small number of genes from domestic cattle. In 2002, the United States government donated some bison calves from South Dakota and Colorado to the Mexican government. Their descendants live in the Mexican nature reserves El Uno Ranch at Janos and Santa Elena Canyon, Chihuahua, and Boquillas del Carmen, Coahuila, located near the southern banks of the Rio Grande, and around the grassland state line with Texas and New Mexico.
+Recent genetic studies of privately owned herds of bison show that many of them include animals with genes from domestic cattle. For example, the herd on Santa Catalina Island, California, isolated since 1924 after being brought there for a movie shoot, were found to have cattle introgression. As few as 12,000 to 15,000 pure bison are estimated to remain in the world. The numbers are uncertain because the tests used to date—mitochondrial DNA analysis—indicate only if the maternal line (back from mother to mother) ever included domesticated bovines, thus say nothing about possible male input in the process. Most hybrids were found to look exactly like purebred bison; therefore, appearance is not a good indicator of genetics.
+The size of the Canadian domesticated herd (genetic questions aside) grew dramatically through the 1990s and 2000s. The 2006 Census of Agriculture reported the Canadian herd at 195,728 head, a 34.9% increase since 2001.  Of this total, over 95% were located in Western Canada, and less than 5% in Eastern Canada. Alberta was the province with the largest herd, accounting for 49.7% of the herd and 45.8% of the farms. The next-largest herds were in Saskatchewan (23.9%), Manitoba (10%), and British Columbia (6%). The main producing regions were in the northern parts of the Canadian prairies, specifically in the parkland belt, with the Peace River region (shared between Alberta and British Columbia) being the most important cluster, accounting for 14.4% of the national herd. Canada also exports bison meat, totaling 2,075,253 kilograms (4,575,150 lb) in 2006.A proposal known as Buffalo Commons has been suggested by a handful of academics and policymakers to restore large parts of the drier portion of the Great Plains to native prairie grazed by bison. Proponents argue that current agricultural use of the shortgrass prairie is not sustainable, pointing to periodic disasters, including the Dust Bowl, and continuing significant human population loss over the last 60 years. However, this plan is opposed by some who live in the areas in question.
+
+
+== Genetics ==
+
+A major problem that bison face today is a lack of genetic diversity due to the population bottleneck the species experienced during its near-extinction event. Another genetic issue is the entry of genes from domestic cattle into the bison population, through hybridization.Officially, the "American buffalo" is classified by the United States government as a type of cattle, and the government allows private herds to be managed as such. This is a reflection of the characteristics that bison share with cattle.  Though the American bison is not only a separate species, but also is usually regarded as being in a separate genus from domestic cattle (Bos taurus), they clearly have a lot of genetic compatibility and American bison can interbreed with cattle, although only the female offspring are fertile in the first generation. These female hybrids can be bred back to either bison or domestic bulls, resulting in either 1/4 or 3/4 bison young. Female offspring from this cross are also fertile, but males are not reliably fertile unless they are either 7⁄8 bison or 7⁄8 domestic. Moreover, when they do interbreed, crossbreed animals in the first generation tend to look very much like purebred bison, so appearance is completely unreliable as a means of determining what is a purebred bison and what is a crossbred cow.  Many ranchers have deliberately crossbred their cattle with bison, and some natural hybridization could be expected in areas where cattle and bison occur in the same range. Since cattle and bison eat similar food and tolerate similar conditions, they have often been in the same range together in the past, and opportunity for crossbreeding may sometimes have been common.
+In recent decades, tests were developed to determine the source of mitochondrial DNA in cattle and bison, and most private "buffalo" herds were actually crossbred with cattle, and even most state and federal buffalo herds had some cattle DNA. With the advent of nuclear microsatellite DNA testing, the number of herds known to contain cattle genes has increased. As of 2011, though about 500,000 bison existed on private ranches and in public herds, perhaps only 15,000 to 25,000 of these bison were pure and not actually bison-cattle hybrids. "DNA from domestic cattle (Bos taurus) has been detected in nearly all bison herds examined to date."  Significant public bison herds that do not appear to have hybridized domestic cattle genes are the Yellowstone Park bison herd, the Henry Mountains bison herd, which was started with bison taken from Yellowstone Park, the Wind Cave bison herd, and the Wood Buffalo National Park bison herd and subsidiary herds started from it, in Canada.
+A landmark study of bison genetics performed by James Derr of Texas A&M University corroborated this. The Derr study was undertaken in an attempt to determine what genetic problems bison might face as they repopulate former areas, and it noted that bison seem to be adapting successfully, despite their apparent genetic bottleneck. One possible explanation for this might be the small amount of domestic cattle genes that are now in most bison populations, though this is not the only possible explanation for bison success.
+
+In the study, cattle genes were also found in small amounts throughout most national, state and private herds. "The hybridization experiments conducted by some of the owners of the five foundation herds of the late 1800s, have left a legacy of a small amount of cattle genetics in many of our existing bison herds." He also said, "All of the state owned bison herds tested (except for possibly one) contain animals with domestic cattle mtDNA."  It appears that the one state herd that had no cattle genes was the Henry Mountains bison herd; the Henry Mountain herd was started initially with transplanted animals from Yellowstone Park. However, the extension of this herd into the Book Cliffs of central Utah involved mixing the founders with additional bison from another source, so it is not known if the Book Cliffs extension of the herd is also free of cattle hybridization.
+A separate study by Wilson and Strobeck, published in Genome, was done to define the relationships between different herds of bison in the United States and Canada, and to determine whether the bison at Wood Buffalo National Park in Canada and the Yellowstone Park bison herd were possibly separate subspecies. The Wood Buffalo Park bison were determined to actually be crossbreeds between plains and wood bison, but their predominant genetic makeup was that of the expected "wood buffalo".  However, the Yellowstone Park bison herd was pure plains bison, and not any of the other previously suggested subspecies. Another finding was that the bison in the Antelope Island herd in Utah appeared to be more distantly related to other plains bison in general than any other plains bison group that was tested, though this might be due to genetic drift caused by the small size of only 12 individuals in the founder population. A side finding of this was that the Antelope Island bison herd appears to be most closely related to the Wood Buffalo National Park bison herd, though the Antelope Island bison are actually plains bison.

+Range history of bison in North America
+		
+		
+		
+In order to bolster the genetic diversity of the American bison, the National Park Service alongside the Department of the Interior announced on May 7, 2020, the 2020 Bison Conservation Initiative. This initiative focuses on maintaining the genetic diversity of the metapopulation rather than individual herds. Small populations of bison are at considerably larger risk due to their decreased gene pool and are susceptible to catastrophic events more so than larger herds. The 2020 Bison Conservation Initiative aims to translocate up to three bison every five to ten years between the Department of the Interior's herds. Specific smaller herds will require a more intense management plan. Translocated bison will also be screened for any health defects such as infection of brucellosis bacteria as to not put the larger herd at risk.

+== As a symbol ==
+
+
+=== Native Americans ===
+
+Among many Native American tribes, especially the Plains Indians, the bison is considered a sacred animal and religious symbol.  According to University of Montana anthropology and Native American studies professor S. Neyooxet Greymorning, "The creation stories of where buffalo came from put them in a very spiritual place among many tribes.  The buffalo crossed many different areas and functions, and it was utilized in many ways. It was used in ceremonies, as well as to make tipi covers that provided homes for people, utensils, shields, weapons and parts were used for sewing with the sinew."  The Sioux consider the birth of a white buffalo to be the return of White Buffalo Calf Woman, their primary cultural prophet and the bringer of their "Seven Sacred Rites".  Among the Mandan and Hidatsa, the White Buffalo Cow Society was the most sacred of societies for women.
+
+
+=== North America ===
+The American bison is often used in North America in official seals, flags, and logos. In 2016, the American bison became the national mammal of the United States. The bison is a popular symbol in the Great Plains states: Kansas, Oklahoma, and Wyoming have adopted the animal as their official state mammal, and many sports teams have chosen the bison as their mascot. In Canada, the bison is the official animal of the province of Manitoba and appears on the Manitoba flag. It is also used in the official coat of arms of the Royal Canadian Mounted Police.
+Several American coins feature the bison, most famously on the reverse side of the "buffalo nickel" from 1913 to 1938. In 2005, the United States Mint coined a nickel with a new depiction of the bison as part of its "Westward Journey" series. The Kansas and North Dakota state quarters, part of the "50 State Quarter" series, each feature bison. The Kansas state quarter has only the bison and does not feature any writing, while the North Dakota state quarter has two bison. The Montana state quarter prominently features a bison skull over a landscape. The Yellowstone National Park quarter also features a bison standing next to a geyser.
+Other institutions which have adopted the bison as a symbol or mascot include:

+The American bison (Bison bison) is a species of bison native to North America. Sometimes colloquially referred to as American buffalo or simply buffalo (a different clade of bovine), it is one of two extant species of bison, alongside  the European bison. Its historical range, by 9000 BC, is described as the great bison belt, a tract of rich grassland that ran from Alaska to the Gulf of Mexico, east to the Atlantic Seaboard (nearly to the Atlantic tidewater in some areas) as far north as New York, south to Georgia and, according to some sources, further south to Florida, with sightings in North Carolina near Buffalo Ford on the Catawba River as late as 1750. Once roaming in vast herds, the species nearly became extinct by a combination of commercial hunting and slaughter in the 19th century and introduction of bovine diseases from domestic cattle.  With a population in excess of 60 million in the late 18th century, the species was culled down to just 541 animals by 1889. Recovery efforts expanded in the mid-20th century, with a resurgence to roughly 31,000 wild bison as of March 2019. For many years, the population was primarily found in a few national parks and reserves. Through multiple reintroductions, the species now freely roams wild in several regions in the United States, Canada, and Mexico, with it also being introduced to Yakutia in Russia.Two subspecies or ecotypes have been described: the plains bison (B. b. bison), smaller in size and with a more rounded hump, and the wood bison (B. b. athabascae)—the larger of the two and having a taller, square hump. Furthermore, the plains bison has been suggested to consist of a northern plains (B. b. montanae) and a southern plains (B. b. bison) subspecies, bringing the total to three. However, this is generally not supported. The wood bison is one of the largest wild species of extant bovid in the world, surpassed only by the Asian gaur. Among extant land animals in North America, the bison is the heaviest and the longest, and the second tallest after the moose.
+Spanning back many millennia, Native American tribes have had cultural and spiritual connections to the American bison. It is the national mammal of the United States of America.
+
+
+== Etymology ==
+
+There are two living species of bison: the American bison and the European bison; and two types of buffalo: the African buffalo, native to Africa, and the water buffalo, native to Asia. Samuel de Champlain applied the term buffalo (buffles in French) to the bison in 1616 (published 1619), after seeing skins and a drawing shown to him by members of the Nipissing First Nation, who said they travelled forty days (from east of Lake Huron) to trade with another nation who hunted the animals. In English usage, the term buffalo dates to 1625 in North America, when the term was first recorded for the American mammal. The word buffalo is derived from the French “bœuf,” a name given to bison when French fur trappers working in the US in the early 1600s saw the animals. The word bœuf came from what the French knew as true buffalo, animals living in Africa and Asia. The term bison was first recorded in 1774, and is the correct scientific terminology.
+In Plains Indian languages in general, male and female bison are distinguished, with each having a different designation rather than there being a single generic word covering both sexes. Thus:
+
+in Arapaho: bii (bison cow), henéécee (bison bull)
+in Lakota: pté (bison cow), tȟatȟáŋka (bison bull)Such a distinction is not a general feature of the language (for example, Arapaho possesses gender-neutral terms for other large mammals such as elk, mule deer, etc.), and so presumably is due to the special significance of the bison in Plains Indian life and culture.
+
+
+== Description ==
+
+A bison has a shaggy, long, dark-brown winter coat, and a lighter-weight, lighter-brown summer coat. Male bison are significantly larger and heavier than females. Plains bison are often in the smaller range of sizes, and wood bison in the larger range. Head-rump lengths at maximum up to 3.5 m (11 ft 6 in) for males and 2.85 m (9 ft 4 in) for females long and the tail adding 30 to 95 cm (1 ft 0 in to 3 ft 1 in). Heights at withers in the species can reach up to 186 to 201 cm (6 ft 1 in to 6 ft 7 in) for B. b. bison and B. b. athabascae respectively. Typically weights can range from 318 to 1,179 kg (701 to 2,599 lb), 460 to 988 kg (1,014 to 2,178 lb) with medians of 730 to 792.5 kg (1,609 to 1,747 lb) (B.b. bison) and 943.6 kg (2,080 lb) (B.b.athabascae) in males, and 360 to 640 kg (790 to 1,410 lb) with medians of 450 to 497.6 kg (992 to 1,097 lb) in females, although the lowest weights probably representing typical weight around the age of sexual maturity at 2 to 3 years of age. The heaviest wild bull for B.b.bison ever recorded weighed 1,270 kg (2,800 lb) while there had been bulls estimated to be 1,400 kg (3,000 lb). B.b.athabascae is significantly larger and heavier on average than B.b.bison while the number of recorded samples for the former was limited after the rediscovery of a relatively pure herd. Elk Island National Park, which has wild populations of both wood and plains bison, has recorded maximum weights for bull bison of 1186 kg (plains) and 1099 kg (wood), but noted that 3/4 of all bison over 1000 kg were wood bison. When raised in captivity and farmed for meat, the bison can grow unnaturally heavy and the largest semidomestic bison weighed 1,724 kg (3,801 lb). The heads and forequarters are massive, and both sexes have short, curved horns that can grow up to 60 cm (2 ft)  long with 90 cm (3 ft) to 124 cm (4 ft) width, which they use in fighting for status within the herd and for defense.
+Bison are herbivores, grazing on the grasses and sedges of the North American prairies. Their daily schedule involves two-hour periods of grazing, resting, and cud chewing, then moving to a new location to graze again. Sexually mature young bulls may try to start mating with cows by the age of two or three years, but if more mature bulls are present, they may not be able to compete until they reach five years of age.
+For the first two months of life, calves are lighter in color than mature bison. One very rare condition is the white buffalo, in which the calf turns entirely white.
+
+
+== Evolution ==
+Bison are members of the tribe Bovini. Genetic evidence from nuclear DNA indicates that the closest living relatives of bison are yaks, with bison being nested within the genus Bos, rendering Bos without including bison paraphyletic. While nuclear DNA indicates that the two living bison species are each others closest living relatives, the mitochondrial DNA of European bison is more closely related to that of domestic cattle and aurochs, which is either suggested to be the result of incomplete lineage sorting or ancient introgression. Bison first appeared in Asia during the Early Pleistocene, around 2.6 million years ago. Bison only arrived in North America 195,000 to 135,000 years ago, during the late Middle Pleistocene, descending from the widespread Siberian steppe bison (Bison priscus), which had migrated through Beringia. Following its first appearance in North America, the bison rapidly differentiated into new species such as the largest of all bison, the long-horned Bison latifrons as well as Bison antiquus. The first appearance of bison in North America is considered to define the regional Rancholabrean faunal stage, due to its major impact on the ecology of the continent. Modern American bison are thought to have evolved from B. antiquus during the Late Pleistocene-Holocene transition via the intermediate form Bison occidentalis.
+
+
+=== Differences from European bison ===
+
+Although they are superficially similar, the American and European bison exhibit a number of physical and behavioral differences. Adult American bison are slightly heavier on average because of their less rangy build, and have shorter legs, which render them slightly shorter at the shoulder. American bison tend to graze more, and browse less than their European relatives, because their necks are set differently. Compared to the nose of the American bison, that of the European species is set farther forward than the forehead when the neck is in a neutral position. The body of the American bison is hairier, though its tail has less hair than that of the European bison. The horns of the European bison point forward through the plane of its face, making it more adept at fighting through the interlocking of horns in the same manner as domestic cattle, unlike the American bison which favors charging. American bison are more easily tamed than the European, and breed more readily with domestic cattle.
+
+
+=== Crossbreeding with cattle ===
+During the population bottleneck, after the great slaughter of American bison during the 1800s, the number of bison remaining alive in North America declined to as low as 541. During that period, a handful of ranchers gathered remnants of the existing herds to save the species from extinction. These ranchers bred some of the bison with cattle in an effort to produce "cattalo" or "beefalo". Accidental crossings were also known to occur. Generally, male domestic bulls were crossed with bison cows, producing offspring of which only the females were fertile. The crossbred animals did not demonstrate any form of hybrid vigor, so the practice was abandoned. The proportion of cattle DNA that has been measured in introgressed individuals and bison herds today is typically quite low, ranging from 0.56 to 1.8%. In the United States, many ranchers are now using DNA testing to cull the residual cattle genetics from their bison herds. The U.S. National Bison Association has adopted a code of ethics which prohibits its members from deliberately crossbreeding bison with any other species.
+
+
+== Range and population ==
+
+Despite being the closest relatives of domestic cattle native to North America, bison were never domesticated by Native Americans. Later attempts of domestication by Europeans prior to the 20th century met with limited success. Bison were described as having a "wild and ungovernable temper"; they can jump close to 1.8 m (6 ft) vertically, and run 55–70 km/h (35–45 mph) when agitated. This agility and speed, combined with their great size and weight, makes bison herds difficult to confine, as they can easily escape or destroy most fencing systems, including most razor wire. The most successful systems involve large, 6-metre (20 ft) fences made from welded steel I beams sunk at least 1.8 m (6 ft) into concrete. These fencing systems, while expensive, require very little maintenance. Furthermore, making the fence sections overlap so the grassy areas beyond are not visible prevents the bison from trying to get to new range.
+Population estimates in 2010 ranged from 400,000 to 500,000, with approximately 20,500 animals in 62 conservation herds and the remainder in approximately 6,400 commercial herds. According to the IUCN, roughly 15,000 bison are considered wild, free-range bison not primarily confined by fencing.
+The Nature Conservancy (TNC) has reintroduced bison to over a dozen nature preserves around the United States. In October 2016, TNC established its easternmost bison herd in the country, at Kankakee Sands nature preserve in Morocco, Newton County, Indiana.  In 2014, U.S Tribes and Canadian First Nations signed a treaty to help with the restoration of bison, the first to be signed in nearly 150 years.
+
+
+=== Habitat and trails ===
+
+American bison live in river valleys, and on prairies and plains.  Typical habitat is open or semiopen grasslands, as well as sagebrush, semiarid lands, and scrublands. Some lightly wooded areas are also known historically to have supported bison.  Bison also graze in hilly or mountainous areas where the slopes are not steep.  Though not particularly known as high-altitude animals, bison in the Yellowstone Park bison herd are frequently found at elevations above 2,400 m (8,000 ft) and the Henry Mountains bison herd is found on the plains around the Henry Mountains, Utah, as well as in mountain valleys of the Henry Mountains to an altitude of 3,000 m (10,000 ft). Reintroduced plains bison in Banff National Park have been observed to roam mountainous areas including high ridges and steep drainages, and archaeological finds indicate some bison historically may have spent their lives within mountains while others may have migrated in and out of mountains.
+Those in Yukon, Canada, typically summer in alpine plateaus above treeline. The first thoroughfares of North America, except for the time-obliterated paths of mastodon or muskox and the routes of the mound builders, were the traces made by bison and deer in seasonal migration and between feeding grounds and salt licks. Many of these routes, hammered by countless hoofs instinctively following watersheds and the crests of ridges in avoidance of lower places' summer muck and winter snowdrifts, were followed by the aboriginal North Americans as courses to hunting grounds and as warriors' paths. They were invaluable to explorers and were adopted by pioneers.
+Bison traces were characteristically north and south, but several key east–west trails were used later as railways. Some of these include the Cumberland Gap through the Blue Ridge Mountains to upper Kentucky. A heavily used trace crossed the Ohio River at the Falls of the Ohio and ran west, crossing the Wabash River near Vincennes, Indiana. In Senator Thomas Hart Benton's phrase saluting these sagacious path-makers, the bison paved the way for the railroads to the Pacific.
+
+
+=== Mexico ===
+
+The southern extent of the historic range of the American bison includes northern Mexico and adjoining areas in the United States as documented by archeological records and historical accounts from Mexican archives from 700 CE to the 19th century. The Janos-Hidalgo bison herd has ranged between Chihuahua, Mexico, and New Mexico, United States, since at least the 1920s. The persistence of this herd suggests that habitat for bison is suitable in northern Mexico. In 2009, genetically pure bison were reintroduced to the Janos Biosphere Reserve in northern Chihuahua adding to the Mexican bison population. In 2020, the second herd was formed in Maderas del Carmen. A private reserve named Jagüey de Ferniza has kept bisons since before the above-mentioned reintroductions in Coahuila.
+
+
+=== Introductions to Siberia ===
+
+Since 2006, an outherd of wood bison sent from Alberta's Elk Island National Park was established in Yakutia, Russia as a practice of pleistocene rewilding; wood bison are the most closely related to the extinct bison species. The bison are adapting well to the cold climate, and Yakutia's Red List officially registered the species in 2019; a second herd was formed in 2020.In Pleistocene Park, there are also 24 plains bison as wood bison could not be acquired.
+
+
+== Behavior and ecology ==
+
+Bison are migratory and herd migrations can be directional as well as altitudinal in some areas. Bison have usual daily movements between foraging sites during the summer. In the Hayden Valley, Wyoming, bison have been recorded traveling, on average, 3 km (2 mi) per day. The summer ranges of bison appear to be influenced by seasonal vegetation changes, interspersion and size of foraging sites, the rut, and the number of biting insects. The size of preserve and availability of water may also be a factor. Bison are largely grazers, eating primarily grasses and sedges. On shortgrass pasture, bison predominately consume warm-season grasses. On mixed prairie, cool-season grasses, including some sedges, apparently compose 79–96% of their diet. In montane and northern areas, sedges are selected throughout the year. Bison also drink water or consume snow on a daily basis.
+
+
+=== Social behavior and reproduction ===
+
+Female bison live in maternal herds which include other females and their offspring. Male offspring leave their maternal herd when around three years old and either live alone or join other males in bachelor herds. Male and female herds usually do not mingle until the breeding season, which can occur from July through September. However, female herds may also contain a few older males. During the breeding season, dominant bulls maintain a small harem of females for mating. Individual bulls "tend" cows until allowed to mate, by following them around and chasing away rival males. The tending bull shields the female's vision with his body so she will not see any other challenging males. A challenging bull may bellow or roar to get a female's attention and the tending bull has to bellow/roar back. The most dominant bulls mate in the first 2–3 weeks of the season. More subordinate bulls mate with any remaining estrous cow that has not mated yet. Male bison play no part in raising the young.
+
+Bison herds have dominance hierarchies that exist for both males and females. A bison's dominance is related to its birth date. Bison born earlier in the breeding season are more likely to be larger and more dominant as adults. Thus, bison are able to pass on their dominance to their offspring as dominant bison breed earlier in the season. In addition to dominance, the older bison of a generation also have a higher fertility rate than the younger ones.Bison mate in August and September; gestation is 285 days. A single reddish-brown calf nurses until the next calf is born. If the cow is not pregnant, a calf will nurse for 18 months. Cows nurse their calves for at least 7 or 8 months, but most calves seem to be weaned before the end of their first year. At three years of age, bison cows are mature enough to produce a calf. The birthing period for bison in boreal biomes is protracted compared to that of other northern ungulates, such as moose and caribou.Bison have a life expectancy around 15 years in the wild and up to 25 years in captivity. However, males and females from a hunted population also subject to wolf predation in northern Canada have been reported to live to 22 and 25 years of age, respectively.Bison have been observed to display homosexual behaviors, males much more so than females. In the case of males, it is unlikely to be related to dominance, but rather to social bonding or gaining sexual experience.
+
+
+=== Horning ===
+Bison mate in late spring and summer in more open plain areas. During fall and winter, bison tend to gather in more wooded areas. During this time, bison partake in horning behaviors. They rub their horns against trees, young saplings, and even utility poles. Aromatic trees like cedars and pine seem to be preferred. Horning appears to be associated with insect defense, as it occurs most often in the fall when the insect population is at its highest. Cedar and pines emit an aroma after bison horn them and this seems to be used as a deterrent for insects.
+
+
+=== Wallowing behavior ===
+ 
+A bison wallow is a shallow depression in the soil, which bison use either wet or dry. Bison roll in these depressions, covering themselves with dust or mud. Past and current hypotheses to explain the purpose of wallowing include grooming associated with shedding, male-male interaction (typically rutting), social behavior for group cohesion, play, relief from skin irritation due to biting insects, reduction of ectoparasite (tick and lice) load, and thermoregulation. Bison wallowing has important ecosystem engineering effects and enhances plant and animal diversity on prairies.
+
+
+=== Predation ===
+
+While often secure from predation because of their size and strength, in some areas, vulnerable individuals are regularly preyed upon by wolves. Wolf predation typically peaks in late winter, when elk migrates south and bison are distressed with heavy snows and shortages of food sources, with attacks usually being concentrated on weakened and injured cows and calves. Wolves more actively target herds with calves than those without. The length of a predation episode varies, ranging from a few minutes to over nine hours. Bison display five apparent defense strategies in protecting calves from wolves: running to a cow; running to a herd; running to the nearest bull; running in the front or center of a stampeding herd; entering water bodies, such as lakes or rivers. When fleeing wolves in open areas, cows with young calves take the lead, while bulls take to the rear of the herds, to guard the cows' escape. Bison typically ignore wolves not displaying hunting behavior. Wolf packs specializing in bison tend to have more males, because their larger size than females allows them to wrestle prey to the ground more effectively. Healthy, mature bulls in herds rarely fall prey.
+Grizzly bears are known to feed on carcass and may steal wolves' kills. While grizzlies can also pose a threat to calves and sometimes old, injured, or sick adult bison, direct killing of non-calves is rare even when targeting lone and injured young individuals; attacking healthy bison is risky for bears, who can be killed instead.
+
+
+=== Dangers to humans ===
+Bison are among the most dangerous animals encountered by visitors to the various North American national parks and will attack humans if provoked. They appear slow because of their lethargic movements, but can easily outrun humans; bison have been observed running as fast as 65 to 70 km/h (40 to 45 mph) for 8 km (5 mi). Bison may approach people for curiosity, and close encounters including to touch the animals can be dangerous, and gunshots do not startle them.
+
+Between 1980 and 1999, more than three times as many people in Yellowstone National Park were injured by bison than by bears. During this period, bison charged and injured 79 people, with injuries ranging from goring puncture wounds and broken bones to bruises and abrasions. Bears injured 24 people during the same time. Three people died from the injuries inflicted—one person by bison in 1983, and two people by bears in 1984 and 1986.
+
+
+== Hunting ==
+
+Buffalo hunting, i.e. hunting of the American bison, was an activity fundamental to the Indigenous peoples of the Great Plains. This activity was later adopted by American professional hunters, as well as by the U.S. government, in an effort to sabotage the central resource of some American Indian Nations during the later portions of the American Indian Wars, leading to the near-extinction of the species around 1890. For many tribes the buffalo was an integral part of life—something guaranteed to them by the Creator. In fact, for some Plains indigenous peoples, bison are known as the first people. The concept of species extinction was foreign to many tribes. Thus, when the U.S. government began to massacre the buffalo, it was particularly harrowing to the Indigenous people. As Crow chief Plenty Coups described it: "When the buffalo went away the hearts of my people fell to the ground, and they could not lift them up again. After this nothing happened. There was little singing anywhere." Spiritual loss was rampant; bison were an integral part of traditional tribal societies and they would frequently take part in ceremonies for each bison they killed to honor its sacrifice. In order to boost morale during this time, Sioux and other tribes took part in the Ghost Dance, which consisted of hundreds of people dancing until 100 persons were lying unconscious.Today, many conservation measures have been taken by Native Americans with the Inter Tribal Bison Council being one of the most significant. It was formed in 1990, composed of 56 tribes in 19 states. These tribes represent a collective herd of more than 15,000 bison and focus on reestablishing herds on tribal lands in order to promote culture, revitalize spiritual solidarity, and restore the ecosystem. Some Inter Tribal Bison Council members argue that the bison's economic value is one of the main factors driving its resurgence. Bison serve as a low cost substitute for cattle, and can withstand the winters in the Plains region far easier than cattle.

+=== As livestock ===
+Bison are increasingly raised for meat, hide, wool, and dairy products. The majority of American bison in the world are raised for human consumption or fur clothing. Bison meat is generally considered to taste very similar to beef, but is lower in fat and cholesterol, yet higher in protein than beef, which has led to the development of beefalo, a fertile hybrid of bison and domestic cattle. In 2005, about 35,000 bison were processed for meat in the U.S., with the National Bison Association and USDA providing a "Certified American Buffalo" program with birth-to-consumer tracking of bison via RFID ear tags. A market even exists for kosher bison meat; these bison are slaughtered at one of the few kosher mammal slaughterhouses in the U.S., and the meat is then distributed nationwide.
+Bison are found in publicly and privately held herds. Custer State Park in South Dakota is home to 1,500 bison, one of the largest publicly held herds in the world, but some question the genetic purity of the animals. Wildlife officials believe that free roaming and genetically pure herds on public lands in North America can be found only in: the Yellowstone Park bison herd; the Henry Mountains bison herd at the Book Cliffs and Henry Mountains in Utah; at Wind Cave National Park in South Dakota; Fort Peck Indian Reservation in Montana; Mackenzie Bison Sanctuary in the Northwest Territories; Elk Island National Park and Wood Buffalo National Park in Alberta; and Prince Albert National Park in Saskatchewan. Another population, the Antelope Island bison herd on Antelope Island in Utah, consisting of 550 to 700 bison, is also one of the largest and oldest public herds in the United States, but the bison in that herd are considered to be only semifree roaming, since they are confined to the Antelope Island. In addition, recent genetic studies indicate that, like most bison herds, the Antelope Island bison herd has a small number of genes from domestic cattle. In 2002, the United States government donated some bison calves from South Dakota and Colorado to the Mexican government. Their descendants live in the Mexican nature reserves El Uno Ranch at Janos and Santa Elena Canyon, Chihuahua, and Boquillas del Carmen, Coahuila, located near the southern banks of the Rio Grande, and around the grassland state line with Texas and New Mexico.
+Recent genetic studies of privately owned herds of bison show that many of them include animals with genes from domestic cattle. For example, the herd on Santa Catalina Island, California, isolated since 1924 after being brought there for a movie shoot, were found to have cattle introgression. As few as 12,000 to 15,000 pure bison are estimated to remain in the world. The numbers are uncertain because the tests used to date—mitochondrial DNA analysis—indicate only if the maternal line (back from mother to mother) ever included domesticated bovines, thus say nothing about possible male input in the process. Most hybrids were found to look exactly like purebred bison; therefore, appearance is not a good indicator of genetics.
+The size of the Canadian domesticated herd (genetic questions aside) grew dramatically through the 1990s and 2000s. The 2006 Census of Agriculture reported the Canadian herd at 195,728 head, a 34.9% increase since 2001.  Of this total, over 95% were located in Western Canada, and less than 5% in Eastern Canada. Alberta was the province with the largest herd, accounting for 49.7% of the herd and 45.8% of the farms. The next-largest herds were in Saskatchewan (23.9%), Manitoba (10%), and British Columbia (6%). The main producing regions were in the northern parts of the Canadian prairies, specifically in the parkland belt, with the Peace River region (shared between Alberta and British Columbia) being the most important cluster, accounting for 14.4% of the national herd. Canada also exports bison meat, totaling 2,075,253 kilograms (4,575,150 lb) in 2006.A proposal known as Buffalo Commons has been suggested by a handful of academics and policymakers to restore large parts of the drier portion of the Great Plains to native prairie grazed by bison. Proponents argue that current agricultural use of the shortgrass prairie is not sustainable, pointing to periodic disasters, including the Dust Bowl, and continuing significant human population loss over the last 60 years. However, this plan is opposed by some who live in the areas in question.
+
+
+== Genetics ==
+
+A major problem that bison face today is a lack of genetic diversity due to the population bottleneck the species experienced during its near-extinction event. Another genetic issue is the entry of genes from domestic cattle into the bison population, through hybridization.Officially, the "American buffalo" is classified by the United States government as a type of cattle, and the government allows private herds to be managed as such. This is a reflection of the characteristics that bison share with cattle.  Though the American bison is not only a separate species, but also is usually regarded as being in a separate genus from domestic cattle (Bos taurus), they clearly have a lot of genetic compatibility and American bison can interbreed with cattle, although only the female offspring are fertile in the first generation. These female hybrids can be bred back to either bison or domestic bulls, resulting in either 1/4 or 3/4 bison young. Female offspring from this cross are also fertile, but males are not reliably fertile unless they are either 7⁄8 bison or 7⁄8 domestic. Moreover, when they do interbreed, crossbreed animals in the first generation tend to look very much like purebred bison, so appearance is completely unreliable as a means of determining what is a purebred bison and what is a crossbred cow.  Many ranchers have deliberately crossbred their cattle with bison, and some natural hybridization could be expected in areas where cattle and bison occur in the same range. Since cattle and bison eat similar food and tolerate similar conditions, they have often been in the same range together in the past, and opportunity for crossbreeding may sometimes have been common.
+In recent decades, tests were developed to determine the source of mitochondrial DNA in cattle and bison, and most private "buffalo" herds were actually crossbred with cattle, and even most state and federal buffalo herds had some cattle DNA. With the advent of nuclear microsatellite DNA testing, the number of herds known to contain cattle genes has increased. As of 2011, though about 500,000 bison existed on private ranches and in public herds, perhaps only 15,000 to 25,000 of these bison were pure and not actually bison-cattle hybrids. "DNA from domestic cattle (Bos taurus) has been detected in nearly all bison herds examined to date."  Significant public bison herds that do not appear to have hybridized domestic cattle genes are the Yellowstone Park bison herd, the Henry Mountains bison herd, which was started with bison taken from Yellowstone Park, the Wind Cave bison herd, and the Wood Buffalo National Park bison herd and subsidiary herds started from it, in Canada.
+A landmark study of bison genetics performed by James Derr of Texas A&M University corroborated this. The Derr study was undertaken in an attempt to determine what genetic problems bison might face as they repopulate former areas, and it noted that bison seem to be adapting successfully, despite their apparent genetic bottleneck. One possible explanation for this might be the small amount of domestic cattle genes that are now in most bison populations, though this is not the only possible explanation for bison success.
+
+In the study, cattle genes were also found in small amounts throughout most national, state and private herds. "The hybridization experiments conducted by some of the owners of the five foundation herds of the late 1800s, have left a legacy of a small amount of cattle genetics in many of our existing bison herds." He also said, "All of the state owned bison herds tested (except for possibly one) contain animals with domestic cattle mtDNA."  It appears that the one state herd that had no cattle genes was the Henry Mountains bison herd; the Henry Mountain herd was started initially with transplanted animals from Yellowstone Park. However, the extension of this herd into the Book Cliffs of central Utah involved mixing the founders with additional bison from another source, so it is not known if the Book Cliffs extension of the herd is also free of cattle hybridization.
+A separate study by Wilson and Strobeck, published in Genome, was done to define the relationships between different herds of bison in the United States and Canada, and to determine whether the bison at Wood Buffalo National Park in Canada and the Yellowstone Park bison herd were possibly separate subspecies. The Wood Buffalo Park bison were determined to actually be crossbreeds between plains and wood bison, but their predominant genetic makeup was that of the expected "wood buffalo".  However, the Yellowstone Park bison herd was pure plains bison, and not any of the other previously suggested subspecies. Another finding was that the bison in the Antelope Island herd in Utah appeared to be more distantly related to other plains bison in general than any other plains bison group that was tested, though this might be due to genetic drift caused by the small size of only 12 individuals in the founder population. A side finding of this was that the Antelope Island bison herd appears to be most closely related to the Wood Buffalo National Park bison herd, though the Antelope Island bison are actually plains bison.
+
+Range history of bison in North America
+		
+		
+		
+In order to bolster the genetic diversity of the American bison, the National Park Service alongside the Department of the Interior announced on May 7, 2020, the 2020 Bison Conservation Initiative. This initiative focuses on maintaining the genetic diversity of the metapopulation rather than individual herds. Small populations of bison are at considerably larger risk due to their decreased gene pool and are susceptible to catastrophic events more so than larger herds. The 2020 Bison Conservation Initiative aims to translocate up to three bison every five to ten years between the Department of the Interior's herds. Specific smaller herds will require a more intense management plan. Translocated bison will also be screened for any health defects such as infection of brucellosis bacteria as to not put the larger herd at risk.

+== As a symbol ==
+
+
+=== Native Americans ===
+
+Among many Native American tribes, especially the Plains Indians, the bison is considered a sacred animal and religious symbol.  According to University of Montana anthropology and Native American studies professor S. Neyooxet Greymorning, "The creation stories of where buffalo came from put them in a very spiritual place among many tribes.  The buffalo crossed many different areas and functions, and it was utilized in many ways. It was used in ceremonies, as well as to make tipi covers that provided homes for people, utensils, shields, weapons and parts were used for sewing with the sinew."  The Sioux consider the birth of a white buffalo to be the return of White Buffalo Calf Woman, their primary cultural prophet and the bringer of their "Seven Sacred Rites".  Among the Mandan and Hidatsa, the White Buffalo Cow Society was the most sacred of societies for women.
+
+
+=== North America ===
+The American bison is often used in North America in official seals, flags, and logos. In 2016, the American bison became the national mammal of the United States. The bison is a popular symbol in the Great Plains states: Kansas, Oklahoma, and Wyoming have adopted the animal as their official state mammal, and many sports teams have chosen the bison as their mascot. In Canada, the bison is the official animal of the province of Manitoba and appears on the Manitoba flag. It is also used in the official coat of arms of the Royal Canadian Mounted Police.
+Several American coins feature the bison, most famously on the reverse side of the "buffalo nickel" from 1913 to 1938. In 2005, the United States Mint coined a nickel with a new depiction of the bison as part of its "Westward Journey" series. The Kansas and North Dakota state quarters, part of the "50 State Quarter" series, each feature bison. The Kansas state quarter has only the bison and does not feature any writing, while the North Dakota state quarter has two bison. The Montana state quarter prominently features a bison skull over a landscape. The Yellowstone National Park quarter also features a bison standing next to a geyser.
+Other institutions which have adopted the bison as a symbol or mascot include:

+The black lemur (Eulemur macaco) is a species of lemur from the family Lemuridae.  Like all lemurs, it is endemic to Madagascar. Originally, the species was thought to have two subspecies, Eulemur macaco macaco and Eulemur macaco flavifrons, both of which were elevated to species status by Mittermeier et al. in 2008 to Eulemur macaco and Eulemur flavifrons respectively. The most startling difference between the two species is the eye colour; Eulemur flavifrons, the blue-eyed black lemur, has blue eyes, while Eulemur macaco, the black lemur, has brown or orange eyes, and also has ear tufts.Both species live in northwest Madagascar. The black lemur occurs in moist forests in the Sambirano region of Madagascar and on nearby islands. The blue-eyed black lemur is restricted to the Sahamalaza Peninsula and adjacent forests. There are reports of the two species hybridizing where their ranges overlap in Manongarivo Special Reserve.
+
+
+== Physical description ==
+
+The black lemur is between 90 and 110 centimeters in length, of which 51–65 centimeters are tail. Weight typically ranges between 1.8 and 2.0 kilograms. The black lemur displays sexual dimorphism in coloration. Males have black or dark chocolate fur, while females' fur is of a lighter brown color, generally medium brown, chestnut brown or even orange-brown. Males have large black ear tufts, while females have large white ear tufts.
+The only other Eulemur species that occurs within the range of the black lemur is the common brown lemur, which overlaps with the black lemur at the extreme southern and eastern edge of its range, and the red-bellied lemur, on the Tsaratanana Massif. The common brown lemur and the red-bellied lemur have different coloration and do not show the extreme sexual dimorphism of the black lemur, making confusion between the black lemur and the other species unlikely.
+
+
+== Diet ==
+
+The black lemur primarily eats fruit, which makes up an estimated 78% of its diet. The ripeness of this fruit is vital to the lemur's diet. Other foods eaten include flowers, leaves, fungi, some invertebrates and, especially during the dry season, nectar.
+
+
+== Behavior ==
+The black lemur lives in both primary and secondary forest. It is active both during the day and at night. It forages in both the upper and middle canopy, especially at night, and during the day it also forages in the understory. In degraded habitats, it also forages on the ground and may even eat soil.The black lemur lives in groups of 2 to 15 members, including approximately equal numbers of males and females. Average group size is about 10 members, although the average may be smaller for E. m. flavifrons. Females are dominant over males, although intragroup fighting is rare.Groups have home ranges of about 3.5 to 7 hectares. Ranges overlap considerably, and population density can reach 200 individuals per square kilometer.Black lemurs also have a habit of picking up and biting at toxic millipedes. The toxins are usually not fatal to the lemurs and they try to stimulate the millipede to release its toxins in self-defence. Once this is achieved the black lemur will rub the millipede around its body to get the toxins on its fur. It is believed that they do this to help repel insects with the millipedes poison.
+
+
+=== Reproduction ===
+Mating usually takes place in April and May. During mating season, antagonism between males increases, and males sometimes roam between groups. After a gestation of about 125 days, a single infant is usually born between late August and early October. Females typically give birth for the first time at two years of age.

+The boa constrictor (scientific name also Boa constrictor), also called the red-tailed boa, is a species of large, non-venomous, heavy-bodied snake that is frequently kept and bred in captivity. The boa constrictor is a member of the family Boidae, found in tropical South America, as well as some islands in the Caribbean. A staple of private collections and public displays, its color pattern is highly variable yet distinctive. Four subspecies are currently recognized. This article focuses on the species Boa constrictor as a whole, and on the nominate subspecies B. c. constrictor.
+
+
+== Common names ==
+Though all boids are constrictors, only this species is properly referred to as a "boa constrictor"—a rare instance of an animal having the same common English name and scientific binomial name.
+All subspecies are referred to as "boa constrictors", and are part of a diverse group of New World boas referred to as "red-tailed" boas, comprising species of both Boa constrictor and Boa imperator. Within the exotic pet trade, it is also known as a "BCC", an abbreviation of its scientific name, to distinguish it from other boa species, such as Boa imperator or "BCI."
+Other common names include chij-chan (Mayan), jiboia (Latin American), and macajuel (Trinidadian).
+
+
+== Subspecies ==
+Several subspecies of Boa constrictor have been described, but many of these are poorly differentiated, and further research may redefine many of them. Some appear to be based more on location, rather than biological differences. Boa imperator, Boa nebulosa and Boa sigma have been elevated to full species status.
+
+Several other subspecies have been described at different times, but currently, these are no longer considered to be subspecies by many herpetologists and taxonomists. They include:
+
+B. c. amarali Stull, 1932
+B. c. melanogaster Langhammer, 1983: a nomen dubium.
+
+
+== Description ==
+
+
+=== Size and weight ===
+The boa constrictor is a large snake, although it is only modestly sized in comparison to other large snakes, such as the reticulated python, Burmese python, or the occasionally sympatric green anaconda, and can reach lengths from 3 to 13 ft (0.91 to 3.96 m) depending on the locality and the availability of suitable prey. Clear sexual dimorphism is seen in the species, with females generally being larger in both length and girth than males. The usual size of mature female boas is between 7 and 10 ft (2.1 and 3.0 m) whereas males are between 6 and 8 ft (1.8 and 2.4 m). Females commonly exceed 10 ft (3.0 m), particularly in captivity, where lengths up to 12 ft (3.7 m) or even 14 ft (4.3 m) can be seen. The largest documented non-stretched dry skin is deposited at Zoologische Staatssammlung München (ZSM 4961/2012) and measures 14.6 ft (4.45 m) without head. A report of a boa constrictor growing up to 18.5 ft (5.6 m) was later found to be a misidentified green anaconda.The boa constrictor is a heavy-bodied snake, and large specimens can weigh up to 27 kg (60 lb). Females, the larger sex, more commonly weigh 10 to 15 kg (22 to 33 lb). Some specimens of this species can reach or possibly exceed 45 kg (100 lb), although this is not usual.The size and weight of a boa constrictor depends on subspecies, locale, and the availability of suitable prey. B. c. constrictor reaches, and occasionally tops, the averages given above, as it is one of the relatively large subspecies of Boa constrictor.Other examples of sexual dimorphism in the species include males generally having longer tails to contain the hemipenes and also longer pelvic spurs, which are used to grip and stimulate the female during copulation. Pelvic spurs are the only external sign of the rudimentary hind legs and pelvis and are seen in all boas and pythons.
+
+
+=== Coloring ===
+
+The coloring of boa constrictors can vary greatly depending on the locality. However, they are generally a brown, gray, or cream base color, patterned with brown or reddish-brown "saddles" that become more pronounced towards the tail. This coloring gives B. constrictor species the common name of "red-tailed boas." The coloring works as a very effective camouflage in the jungles and forests of its natural range.
+Some individuals exhibit pigmentary disorders, such as albinism. Although these individuals are rare in the wild, they are common in captivity, where they are often selectively bred to make a variety of different color "morphs". Boa constrictors have an arrow-shaped head with very distinctive stripes on it: One runs dorsally from the snout to the back of the head; the others run from the snout to the eyes and then from the eyes to the jaw.
+
+Boa constrictors can sense heat via cells in their lips, though they lack the labial pits surrounding these receptors seen in many members of the family Boidae. Boa constrictors also have two lungs, a smaller (non-functional) left and an enlarged (functional) right lung to better fit their elongated shape, unlike many colubrid snakes, which have completely lost the left lung.
+
+
+== Distribution and habitat ==
+
+Depending on the subspecies, Boa constrictor can be found through South America north of 35°S (Colombia, Ecuador, Peru, Venezuela, Trinidad and Tobago, Guyana, Suriname, French Guiana, Brazil, Bolivia, Uruguay, and Argentina), and many other islands along the coasts of South America. An introduced population exists in extreme southern Florida, and a small population on St. Croix in the U.S. Virgin Islands now appears to be reproducing in the wild.
+The type locality given is "Indiis"—a mistake, according to Peters and Orejas-Miranda (1970).B. constrictor flourishes in a wide variety of environmental conditions, from tropical rainforests to arid semidesert country. However, it prefers to live in rainforest due to the humidity and temperature, natural cover from predators, and vast amount of potential prey. It is commonly found in or along rivers and streams, as it is a very capable swimmer. Boa constrictors also occupy the burrows of medium-sized mammals, where they can hide from potential predators.
+
+
+== Behavior ==
+
+Boa constrictors generally live on their own and do not interact with any other snakes unless they want to mate. They are nocturnal, but they may bask during the day when night-time temperatures are too low. As semi-arboreal snakes, young boa constrictors may climb into trees and shrubs to forage; however, they become mostly terrestrial as they become older and heavier. Boa constrictors strike when they perceive a threat. Their bite can be painful, especially from large snakes, but is rarely dangerous to humans. Specimens from Central America are more irascible, hissing loudly and striking repeatedly when disturbed, while those from South America tame down more readily. Like all snakes, boa constrictors in a shed cycle are more unpredictable, because the substance that lubricates between the old skin and the new makes their eyes appear milky, blue, or opaque so that the snake cannot see very well, causing it to be more defensive than it might otherwise be.
+
+
+=== Hunting and diet ===
+
+Their prey includes a wide variety of small to medium-sized mammals and birds. The bulk of their diet consists of rodents, but larger lizards and mammals as big as monkeys, wild pigs and ocelots are also reported to have been consumed. Young boa constrictors eat small mice, birds, bats, lizards, and amphibians. The size of the prey item increases as they get older and larger.
+Boa constrictors are ambush predators, so they often lie in wait for an appropriate prey to come along, then they attack a moment before the prey can escape. However, they have also been known to actively hunt, particularly in regions with a low concentration of suitable prey, and this behavior generally occurs at night. The boa first strikes at the prey, grabbing it with its teeth; it then proceeds to constrict the prey until death before consuming it whole. Unconsciousness and death likely result from shutting off vital blood flow to the heart and brain, rather than suffocation as was previously believed; constriction can interfere with blood flow and overwhelm the prey's usual blood pressure and circulation. This would lead to unconsciousness and death very quickly. Their teeth also help force the animal down the throat while muscles then move it toward the stomach. It takes the snake about 4–6 days to fully digest the food, depending on the size of the prey and the local temperature. After this, the snake may not eat for a week to several months, due to its slow metabolism.
+
+
+=== Reproduction and development ===
+
+Boa constrictors are viviparous, giving birth to live young. They generally breed in the dry season—between April and August—and are polygynous; thus, males may mate with multiple females. Half of all females breed in a given year, and a larger percentage of males actively attempt to locate a mate. Due to their polygynous nature, many of these males will be unsuccessful. As such, female boas in inadequate physical condition are unlikely to attempt to mate, or to produce viable young if they do mate. Reproduction in boas is almost exclusively sexual. In 2010, a boa constrictor was shown to have reproduced asexually via parthenogenesis. The Colombian rainbow boa (Epicrates maurus) was found to reproduce by facultative parthenogenesis resulting in production of WW female progeny. The WW females were likely produced by terminal automixis (see Figure), a type of parthenogenesis in which two terminal haploid products of meiosis fuse to form a zygote, which then develops into a daughter progeny. This is only the third genetically confirmed case of consecutive virgin births of viable offspring from a single female within any vertebrate lineage. In 2017, boa constrictors, along with Boa imperators and Burmese pythons, were found to contain a new set of sex determining chromosomes. Males were discovered to contain a pair of XY sex determining chromosomes, while females have a XX pair. This is the first time snakes were thought to contain male heterogamety, and since then has been found in ball pythons (Python regius) as well.During the breeding season, the female boa emits pheromones from her cloaca to attract males, which may then wrestle to select one to breed with her. During breeding, the male curls his tail around the female's and the hemipenes (or male reproductive organs) are inserted. Copulation can last from a few minutes to several hours and may occur several times over a period of a few weeks. After this period, ovulation may not occur immediately, but the female can hold the sperm inside her for up to one year. When the female ovulates, a midbody swell can be noticed that appears similar to the snake having eaten a large meal. The female then sheds two to three weeks after ovulation, in what is known as a post-ovulation shed which lasts another 2–3 weeks, which is longer than a normal shed. The gestation period, which is counted from the postovulation shed, is around 100–120 days. The female then gives birth to young that average 15–20 in (38–51 cm) in length. The litter size varies between females but can be between 10 and 65 young, with an average of 25, although some of the young may be stillborn or unfertilized eggs known as "slugs". The young are independent at birth and grow rapidly for the first few years, shedding regularly (once every one to two months). At 3–4 years, boa constrictors become sexually mature and reach the adult size of 6–10 feet (1.8–3.0 m), although they continue to grow at a slow rate for the rest of their lives. At this point, they shed less frequently, about every 2–4 months.
+
+
+== Captivity ==
+This species does well in captivity, usually becoming quite tame. It is a common sight in both zoos and private reptile collections. Though still exported from their native South America in significant numbers, they are widely bred in captivity. When kept in captivity, they are fed mice, rats, rabbits, chickens, and chicks depending on the size and age of the individual. Captive life expectancy is 20 to 30 years, with rare accounts over 40 years, making them a long-term commitment as a pet. The greatest reliable age recorded for a boa constrictor in captivity is 40 years, 3 months, and 14 days. This boa constrictor was named Popeye and died in the Philadelphia Zoo, Pennsylvania, on April 15, 1977. Proper animal husbandry is the most significant factor in captive lifespan; this includes providing adequate space, correct temperatures and humidity, and suitable food items.Up to 41.5% of captive boas test positive for eosinophilic inclusion bodies.
+
+
+== Economic significance ==
+Boa constrictors are very popular within the exotic pet trade and have been both captured in the wild and bred in captivity. Today, most captive boa constrictors are captive-bred, but between 1977 and 1983, 113,000 live boa constrictors were imported into the United States. These huge numbers of wild-caught snakes have put considerable pressure on some wild populations. Boa constrictors have also been hunted for their meat and skins, and are a common sight at markets within their geographic range. After the reticulated python, boa constrictors are the snake most commonly killed for snakeskin products, such as shoes, bags, and other items of clothing. In some areas, they have an important role in regulating the opossum populations, preventing the potential transmission of leishmaniasis to humans. In other areas, they are often let loose within the communities to control the rodent populations.
+
+
+== Conservation ==
+All boa constrictors fall under CITES and are listed under CITES Appendix II, except B. c. occidentalis, which is listed in CITES Appendix I.In some regions, boa constrictor numbers have been severely hit by predation from humans and other animals and over-collection for the exotic pet and snakeskin trades. Most populations, though, are not under threat of immediate extinction; thus, they are within Appendix II rather than Appendix I.Boa constrictors may be an invasive species in Florida.

+The American (North and South America) horned owls and the Old World eagle-owls make up the genus Bubo, at least as traditionally described. The genus name Bubo is Latin for the Eurasian eagle-owl.
+This genus contains 19 species that are found in many parts of the world. Some of the largest living Strigiformes are in Bubo. Traditionally, only owls with ear-tufts were included in this genus, but that is no longer the case.
+
+
+== Taxonomy ==
+
+The genus Bubo was introduced in 1805 by André Duméril for the horned owls. The type species is the Eurasian eagle-owl. The word bubo is Latin for the Eurasian eagle owl and was used as the specific epithet for the species by Carl Linnaeus in 1758.A molecular phylogenetic study published in 2019 found that species in the genera Scotopelia and Ketupa were embedded within the clade containing members of the genus Bubo. Thus, the genus Bubo as currently defined is paraphyletic.Systematics of which species to include among the horned owls is in an upheaval at present. While Mitochondrial DNA (mtDNA) cytochrome b sequence data favors the decision by some to regard the snowy owl as an eagle-owl adapted to Arctic conditions, moving it into Bubo, this is not accepted by all authorities, many still preferring Nyctea.Likewise disagreement exists over the decision by some to move the four fish-owls previously in the genus Ketupa provisionally into Bubo as well, which introduces a good bit of confusion. While the mtDNA cytochrome b data suggests that in this case, to make Bubo monophyletic the Scotopelia fishing owls would also need to be included there. On the other hand, the genus then becomes quite large and ill-defined, and Bubo in the expanded sense seems to consist of two distinct clades. Thus, the fish and fishing owls can alternatively be united in Ketupa if some aberrant eagle-owls – at least the barred, spot-bellied and Usambara eagle-owls, perhaps also Fraser's eagle-owl and maybe others – are moved into that genus too. As some enigmatic eagle-owls remain essentially unstudied and others – e.g. Verreaux's eagle-owl – are of unresolved relationships, more research is needed.

+
+=== Fossil record ===
+Named and distinct Bubo species are:
+
+Bubo florianae (Late Miocene of Csákvár, Hungary, tentatively placed here)
+Bubo leakeyae (Early Pleistocene of Tanzania)
+Bubo binagadensis (Late Pleistocene of Binagady, Azerbaijan)
+Bubo osvaldoi (Pleistocene of Cuba)
+Bubo insularis (Pleistocene of Sardinia)Some notable undescribed fossils of prehistoric horned owls, usually quite fragmentary remains, have also been recorded:
+
+Bubo sp. (Late Pliocene of Senèze, France)
+Bubo sp. (Late Pliocene of Rębielice Królewskie, Poland; tentatively placed here)
+Bubo sp. (Late Pleistocene of San Josecito Cavern, Mexico)Specimen UMMP V31030, a Late Pliocene coracoid from the Rexroad Formation of Kansas (USA), cannot be conclusively assigned to either Bubo or Strix. This fossil is from a taxon similar in size to the great horned owl (B. virginianus) or the great grey owl (S. nebulosa).The Sinclair owl (Bubo sinclairi) from Late Pleistocene California may have been a paleosubspecies of the great horned owl, while the roughly contemporary Bubo insularis of the central and eastern Mediterranean has been considered a junior synonym of a brown fish owl paleosubspecies. Additional paleosubspecies are discussed on the appropriate species page.
+Several presumed Bubo fossils have turned out to be from different birds. The Late Eocene/Early Oligocene eared owls "Bubo" incertus and "Bubo" arvernensis are now placed in the fossil barn-owl genera Nocturnavis and Necrobyas, respectively. "Bubo" leptosteus is now recognized as primitive owl in the genus Minerva (formerly Protostrix). "Bubo" poirreiri from the Late Oligocene or Early Miocene of Saint-Gérard-le-Puy in France, is now placed in Mioglaux.
+On the other hand, the supposed fossil heron "Ardea" lignitum from the Late Pliocene of Plaue-Rippersroda (Germany) was apparently an owl and close to Bubo or more probably actually belongs here. Given its age – about 2 million years ago or so – it is usually included in the Eurasian eagle-owl today.
+
+
+== Interactions with humans ==
+Because of their nocturnal habits, most owls do not directly interact with humans. However, in 2015, an eagle owl in Purmerend, Netherlands, attacked some fifty humans before it was caught by a hired falconer.

+The Eurasian eagle-owl (Bubo bubo) is a species of eagle-owl that resides in much of Eurasia. It is also called the Uhu and it is occasionally abbreviated to just the eagle-owl in Europe. It is one of the largest species of owl, and females can grow to a total length of 75 cm (30 in), with a wingspan of 188 cm (6 ft 2 in), with males being slightly smaller. This bird has distinctive ear tufts, with upper parts that are mottled with darker blackish colouring and tawny. The wings and tail are barred. The underparts are a variably hued buff, streaked with darker colouring. The facial disc is not very defined and the orange eyes are distinctive.Eurasian eagle-owls are found in many habitats, but are mostly birds of mountainous regions or other rocky areas, often those near varied woodland edge and shrubby areas with openings or wetlands to hunt a majority of their prey. Additionally, they inhabit coniferous forests, steppes, and other areas at varied elevations that are typically relatively remote. Eurasian eagle-owls are occasionally found amongst farmland and in park-like settings within European cities, even rarely within busier urban areas. The eagle-owl is mostly a nocturnal predator, hunting for a range of different prey species. Predominantly, their diet is composed of small mammals such as rodents and rabbits, but they also prey on larger mammals and birds of varying sizes. Other secondary prey can include reptiles, amphibians, fish, large insects and other assorted invertebrates. The species typically breeds on cliff ledges, in gullies, among rocks, or in other concealed locations. The nest is a scrape containing a clutch of two eggs typically, which are laid at intervals and hatch at different times. The female incubates the eggs and broods the young, and the male provides food for her, and when they hatch, for the nestlings, as well. Continuing parental care for the young is provided by both adults for about five months. At least 12 subspecies of the Eurasian eagle-owl are described.In addition to being one of the largest living species of owl, the Eurasian eagle-owl is also one of the most widely distributed. With a total range in Europe and Asia of about 32 million km2 (12 million sq mi) and a total population estimated to be between 250,000 and 2.5 million, the IUCN lists the bird's conservation status as being of least concern.  The vast majority of eagle-owls live in Continental Europe, Scandinavia, Russia (which is almost certainly where the peak numbers and diversity of race occurs), and Central Asia. Additional minor populations exist in Anatolia, the northern Middle East, the montane upper part of South Asia and in China; in addition, an estimated 12 to 40 pairs are thought to reside in the United Kingdom as of 2016 (where they are arguably non-native), a number which may be on the rise. Tame eagle-owls have occasionally been used in pest control because of their size to deter large birds such as gulls from nesting.
+
+
+== Description ==
+
+The Eurasian eagle-owl is among the larger birds of prey, smaller than the golden eagle (Aquila chrysaetos), but larger than the snowy owl (Bubo scandiacus), despite some overlap in size with both of those species. It is sometimes referred to as the world's largest owl, although Blakiston's fish owl (B. blakistoni) is slightly heavier on average and the much lighter weight great grey owl (Strix nebulosa) is slightly longer on average. Heimo Mikkola reported the largest specimens of eagle-owl as having the same upper body mass, 4.6 kg (10 lb), as the largest Blakiston’s fish owl and attained a length around 3 cm (1.2 in) longer. In terms of average weight and wing size, the Blakiston’s is the slightly larger species seemingly, even averaging a bit larger in these aspects than the biggest eagle-owl races from Russia. Also, although 9 cm (3.5 in) shorter than the largest of the latter species, the Eurasian eagle-owl can weigh well more than twice as much as the largest great grey owl. The Eurasian eagle-owl typically has a wingspan of 131–188 cm (4 ft 4 in – 6 ft 2 in), with the largest specimens possibly attaining 200 cm (6 ft 7 in). The total length of the species can vary from 56 to 75 cm (22 to 30 in). Females can weigh from 1.75 to 4.6 kg (3.9 to 10.1 lb), and males can weigh from 1.2 to 3.2 kg (2.6 to 7.1 lb). In comparison, the barn owl (Tyto alba), the world's most widely distributed owl species, weighs about 500 g (1.1 lb) and the great horned owl (B. virginianus), which fills the eagle-owl's ecological niche in North America, weighs around 1.4 kg (3.1 lb).
+
+Besides the female being larger,  little external sexual dimorphism is seen in the Eurasian eagle-owl, although the ear tufts of males reportedly tend to be more upright than those of females. When an eagle-owl is seen on its own in the field, distinguishing the individual’s sex is generally not possible. Gender determination by size is possible by in-hand measurements. In some populations, the female typically may be slightly darker than the male. The plumage coloration across at least 13 accepted subspecies can be highly variable. The upper parts may be brown-black to tawny-buff to pale creamy gray, typically showing dense freckling on the forehead and crown, stripes on the nape, sides, and back of the neck, and dark splotches on the pale ground colour of the back, mantle, and scapulars. A narrow buff band, freckled with brown or buff, often runs up from the base of the bill, above the inner part of the eye, and along the inner edge of the black-brown ear tufts. The rump and upper tail-coverts are delicately patterned with dark vermiculations and fine, wavy barring, the extent of which varies with subspecies. The underwing coverts and undertail coverts are similar, but tend to be more strongly barred in brownish-black.The primaries and secondaries are brown with broad, dark brown bars and dark brown tips, and grey or buff irregular lines. A complete moult takes place each year between July and December. The facial disc is tawny-buff, speckled with black-brown, so densely on the outer edge of the disc as to form a "frame" around the face. The chin and throat are white with a brownish central streak. The feathers of the upper breast generally have brownish-black centres and reddish-brown edges except for the central ones, which have white edges. The chin and throat may appear white continuing down the center of the upper breast. The lower breast and belly feathers are creamy-brown to tawny buff to off-white with a variable amount of fine dark wavy barring, on a tawny-buff ground colour. The legs and feet (which are feathered almost to the talons) are likewise marked on a buff ground colour but more faintly. The tail is tawny-buff, mottled dark grey-brown with about six black-brown bars. The bill and feet are black. The iris is most often orange but is fairly variable. In some European birds, the iris is a bright reddish, blood-orange colour but then in subspecies found in arid, desert-like habitats, the iris can range into an orange-yellow colour (most closely related species generally have yellowish irises, excluding the Indian eagle-owl).
+
+
+=== Standard measurements and physiology ===
+
+Among standard measurements for the Eurasian eagle-owl, the wing chord measures 378 to 518 mm (14.9 to 20.4 in), the tail measures 229–310 mm (9.0–12.2 in) long, the tarsus measures 64.5–112 mm (2.54–4.41 in), and the total length of the bill is 38.9–59 mm (1.53–2.32 in). The wings are reportedly the smallest in proportion to the body weight of any European owl, when measured by the weight per area of wing size, was found to be 0.72 g/cm2. Thus, they have quite high wing loading. The great horned owl has even smaller wings (0.8 g/cm2) relative to its body size. The golden eagle has slightly lower wing loading proportionately (0.65 g/cm2), so the aerial abilities of the two species (beyond the eagle’s spectacular ability to stoop) may not be as disparate as expected. Some other owls, such as barn owls, short-eared owls (Asio flammeus), and even the related snowy owls have lower wing loading relative to their size, so are presumably able to fly faster, with more agility, and for more extended periods than the Eurasian eagle-owl. In the relatively small race B. b. hispanus, the middle claw, the largest talon, (as opposed to rear hallux-claw, which is the largest in accipitrids) was found to measure from 21.6 to 40.1 mm (0.85 to 1.58 in) in length. A 3.82 kg (8.4 lb) female examined in Britain (origins unspecified) had a middle claw measuring 57.9 mm (2.28 in), on par in length with a large female golden eagle hallux-claw. Generally, owls do not have talons as proportionately large as those of accipitrids, but have stronger, more robust feet relative to their size. Accipitrids use their talons to inflict organ damage and blood loss, whereas typical owls use their feet to constrict their prey to death, the talons serving only to hold the prey in place or provide incidental damage. The talons of the Eurasian eagle-owl are very large and not often exceeded in size by diurnal raptors. Unlike the great horned owls, the overall foot size and strength of the Eurasian eagle-owl is not known to have been tested, but the considerably smaller horned owl has one of the strongest grips ever measured in a bird.The feathers of the ear tufts in Spanish birds (when not damaged) were found to measure from 63.3 to 86.6 mm (2.49 to 3.41 in). The ear openings (covered in feathers as in all birds) are relatively uncomplicated for an owl, but are also large, being larger on the right than on the left as in most owls, and proportionately larger than those of the great horned owl. In the female, the ear opening averages 31.7 mm (1.25 in) on the right and 27.4 mm (1.08 in) on the left, and in males, averages 26.8 mm (1.06 in) on the right and 24.4 mm (0.96 in) on the left. The depth of the facial disc and the size and complexity of the ear opening are directly correlated to the importance of sound in an owl’s hunting behaviour. Examples of owls with more complicated ear structures and deeper facial disc are barn owls, long-eared owls (Asio otus), and boreal owls (Aegolius funereus). Given the uncomplicated structure of their ear openings and relatively shallow, undefined facial discs, hunting by ear is secondary to hunting by sight in  eagle-owls; this seems to be true for Bubo in general. More sound-based hunters such as the aforementioned species likely focus their hunting activity in more complete darkness. Also, owls with white throat patches such as the Eurasian eagle-owl are more likely to be active in low-light conditions in the hours before and after sunrise and sunset rather than the darkest times in the middle of the night. The boreal and barn owls, to extend these examples, lack obvious visual cues such as white throat patches (puffed up in displaying eagle-owls), again indicative of primary activity being in darker periods.
+
+
+=== Distinguishing from other species ===
+The great size, bulky, barrel-shaped build, erect ear tufts, and orange eyes render this as a distinctive species. Other than general morphology, the above features differ markedly from those of two of the next largest subarctic owl species in Europe and western Asia, which are the great grey owl and the greyish to chocolate-brown Ural owl (Strix uralensis), both of which have no ear tufts and have a distinctly rounded head, rather than the blocky shape of the eagle-owl’s head. The snowy owl is obviously distinctive from most eagle-owls, but during winter the palest Eurasian eagle-owl race (B. b. sibiricus) can appear off-white. Nevertheless, the latter is still distinctively an ear-tufted Eurasian eagle-owl and lacks the pure white background colour and variable blackish spotting of the slightly smaller species (which has relatively tiny, vestigial ear tufts that have only been observed to have flared on rare occasions).
+
+The long-eared owl has a somewhat similar plumage to the eagle-owl, but is considerably smaller (an average female eagle-owl may be twice as long and 10 times heavier than an average long-eared owl). Long-eared owls in Eurasia have vertical striping like that of the Eurasian eagle-owl, while long-eared owls in North America show a more horizontal striping like that of great horned owls. Whether these are examples of mimicry either way is unclear but it is known that both Bubo owls are serious predators of long-eared owls. The same discrepancy in underside streaking has also been noted in the Eurasian and American representations of the grey owl. A few other related species overlap minimally in range in Asia, mainly in East Asia and the southern reaches of the Eurasian eagle-owl’s range. Three fish owls appear to overlap in range, the brown (Ketupa zeylonensis) in at least northern Pakistan, probably Kashmir, and discontinuously in southern Turkey, the tawny (K. flavipes) through much of eastern China, and Blakiston's fish owl in the Russian Far East, northeastern China, and Hokkaido. Fish owls are distinctively different looking, possessing more scraggy ear tufts that hang to the side rather than sit erect on top of the head, and generally have more uniform, brownish plumages without the contrasting darker streaking of an eagle-owl. The brown fish owl has no feathering on the tarsus or feet, and the tawny has feathering only on the upper portion of the tarsi, but the Blakiston’s is nearly as extensively feathered on the tarsi and feet as the eagle-owl. Tawny and brown fish owls are both slightly smaller than co-occurring Eurasian eagle-owls, and Blakiston’s fish owls are similar or slightly larger than co-occurring large northern eagle-owls. Fish owls, being tied to the edges of fresh water, where they hunt mainly fish and crabs, also have slightly differing, and more narrow, habitat preferences.In the lower Himalayas of northern Pakistan and Jammu and Kashmir, along with the brown fish owl, the Eurasian eagle-owl at the limit of its distribution may co-exist with at least two to three other eagle-owls. One of these, the dusky eagle-owl (B. coromandus) is smaller, with more uniform tan-brownish plumage, untidy uniform light streaking rather than the Eurasian’s dark streaking below and an even less well-defined facial disc. The dusky is usually found in slightly more enclosed woodland areas than Eurasian eagle-owls. Another is possibly the spot-bellied eagle-owl (B. nipalensis), which is strikingly different looking, with stark brown plumage, rather than the warm hues typical of the Eurasian, bold spotting on a whitish background on the belly, and somewhat askew ear tufts that are bold white with light brown crossbars on the front. Both species may occur in some parts of the Himalayan foothills, but they are not currently verified to occur in the same area, in part because of the spot-bellied’s preference for dense, primary forest. Most similar, with basically the same habitat preferences and the only one verified to co-occur with the Eurasian eagle-owls of the race B. b. turcomanus in Kashmir is the Indian eagle-owl (B. bengalensis). The Indian species is smaller, with a bolder, blackish facial disc border, more rounded and relatively smaller wings, and partially unfeathered toes. Far to the west, the pharaoh eagle-owl (B. ascalaphus) also seemingly overlaps in range with the Eurasian, at least in Jordan. Although also relatively similar to the Eurasian eagle-owl, the pharaoh eagle-owl is distinguished by its smaller size, paler, more washed-out plumage, and the diminished size of its ear tufts.
+
+
+=== Moulting ===
+The Eurasian eagle-owls’ feathers are lightweight and robust, but nevertheless need to be replaced periodically as they become worn. In the Eurasian eagle-owl, this happens in stages, and the first moult starts the year after hatching with some body feathers and wing coverts being replaced. The next year, the three central secondaries on each wing and three middle tail feathers are shed and regrow, and the following year, two or three primaries and their coverts are lost. In the final year of this postjuvenile moult, the remaining primaries are moulted and all the juvenile feathers will have been replaced. Another moult takes place during years 6-12 of the bird's life. This happens between June and October after the conclusion of the breeding season, and again it is a staged process with six to nine main flight feathers being replaced each year. Such a moulting pattern lasting several years is repeated throughout the bird's life.

+
+== Taxonomy ==
+The Eurasian eagle-owl was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Strix bulbo. Although Linnaeus specified the "habitat" as "Europa" the type locality is restricted to Sweden. The Eurasian eagle-owl  is now placed in the genus Bubo that was introduced by André Duméril in 1805.The genus Bubo with 20 extant species includes most of the larger owl species in the world today. Based on an extensive fossil record and a central distribution of extant species on that continent,  Bubo appears to have evolved into existence in Africa, although early radiations seem to branch from southern Asia, as well. Two genera belonging to the scops owls complex, the giant scops owls (Otus gurneyi) found in Asia and the Ptilopsis or the white-faced scops owl found in Africa, although firmly ensconced in the scops owl group, appear to share some characteristics with the eagle-owls. The Strix genus is also related to Bubo, and is considered a "sister complex", with Pulsatrix possibly being intermediate between the two. The Eurasian eagle-owl appears to represent an expansion of the genus Bubo into the Eurasian continent. A few of the other species of Bubo seem to have been derived from the Eurasian eagle-owl, making it a "paraspecies", or they at least share a relatively recent common ancestor.The pharaoh eagle-owl, distributed in the Arabian Peninsula and sections of the Sahara Desert through North Africa where rocky outcrops are found, was until recently considered a subspecies of the Eurasian eagle-owl. The pharaoh eagle-owl apparently differs about 3.8% in mitochondrial DNA from the Eurasian eagle-owl, well past the minimum genetic difference to differentiate species of 1.5%. Smaller and paler than Eurasian eagle-owls, the pharaoh eagle-owl can also be considered a distinct species largely due to its higher-pitched and more descending call, and the observation that Eurasian eagle-owls formerly found in Morocco (B. b. hispanus) apparently did not breed with the co-existing pharaoh eagle-owls. On the contrary, the race still found together with the pharaoh eagle-owl in the wild (B. b. interpositus) in the central Middle East has been found to interbreed in the wild with the pharaoh eagle-owl, although genetical materials have indicated B. b. interpositus may itself be a distinct species from the Eurasian eagle-owl, as it differs from the nominate subspecies of the Eurasian eagle-owl by 2.8% in mitochondrial DNA. For three Asian Eurasian eagle-owl subspecies (B. b. ussuriensis, B. b. kiautschensis and B. b. hemachlana, respectively), it was found that they met the criterion for subspecies well, with a high haplotype diversity and in spite of a relatively recent common ancestor and low genetic diversity.  The Indian eagle-owl (B. bengalensis) was also considered a subspecies of the Eurasian eagle-owl until recently, but its smaller size, distinct voice (more clipped and high-pitched than the Eurasian), and the fact that it is largely allopatric in distribution (filling out the Indian subcontinent) with other Eurasian eagle-owl races has led to it being considered a distinct species. The mitochondrial DNA of the Indian species also appears considerably distinct from the Eurasian species. The Cape eagle-owl (B. capensis) appears to represent a return of this genetic line back into the African continent, where it leads a lifestyle similar to Eurasian eagle-owls, albeit far to the south. Another offshoot of the northern Bubo group is the snowy owl. It appears to have separated from other Bubo species at least 4 million years ago.The fourth and most famous derivation of the evolutionary line that includes the Eurasian eagle-owl is the great horned owl, which appears to have been the result of primitive eagle-owls spreading into North America. According to some authorities, the great horned owls and Eurasian eagle-owls are barely distinct as species, with a similar level of divergence in their plumages as the Eurasian and North American representations of the great grey owl or the long-eared owl. More outward physical differences exist between the great horned owl and the Eurasian eagle-owl than in those two examples, including a great size difference favoring the Eurasian species, the great horned owl’s horizontal rather than vertical underside barring, yellow rather than orange eyes, and a much stronger black bracket to the facial disc, not to mention a number of differences in their reproductive behaviour and distinctive voices. Furthermore, genetic research has revealed that the snowy owl is more closely related to the great horned owl than are Eurasian eagle-owls. The most closely related species beyond the pharaoh, Indian, and Cape eagle-owls to the Eurasian eagle-owl is the smaller, less powerful and African spotted eagle-owl (B. africanus), which was likely to have divided from the line before they radiated away from Africa. Somehow, genetic materials indicate the spotted eagle-owl appears to share a more recent ancestor with the Indian eagle-owl than with the Eurasian eagle-owl or even the sympatric Cape eagle-owl. Eurasian eagle-owls in captivity have produced apparently healthy hybrids with both the Indian eagle-owl and the great horned owl. The pharaoh, Indian, and Cape eagle-owls and the great horned owl are all broadly similar in size to each other, but all are considerably smaller than the Eurasian eagle-owl, which averages at least 15–30% larger in linear dimensions and 30–50% larger in body mass than these other related species, possibly as the eagle-owls adapted to warmer climates and smaller prey. Fossils from southern France have indicated that during the Middle Pleistocene, Eurasian eagle-owls (this paleosubspecies is given the name B. b. davidi) were larger than they are today, even larger were those found in Azerbaijan and in the Caucasus (either B. b. bignadensis or B. bignadensis), which were deemed to date to the Late Pleistocene. About 12 subspecies are recognized today.

+=== Subspecies ===
+
+B. b. bubo (Linnaeus, 1758) – Also known as the European eagle-owl, the nominate subspecies inhabits continental Europe from near the Arctic Circle in Norway, Sweden, Finland, the southern Kola Peninsula, and Arkhangelsk where it ranges north to about latitude 64° 30' N., southward to the Baltic Sea, central Germany, to southeastern Belgium, eastern, central, and southern France to Italy and Sicily, and through Central and Southeastern Europe to Greece. It intergrades with B. b. ruthenus in northern Russia around the basin of the upper Mezen River and in the eastern vicinity of Gorki Leninskiye, Tambov and Voronezh, and intergrades with B. b. interpositus in northern Ukraine. This is a medium-sized race, measuring in wing chord length 435–480 mm (17.1–18.9 in) in males and 455–500 mm (17.9–19.7 in). In captive owls of this subspecies, the mean wingspan were 157 cm (5 ft 2 in) for males and 167.5 cm (5 ft 6 in) for females. The total bill length is 45 to 56 mm (1.8 to 2.2 in). Adult male European eagle-owls from Norway weigh 1.63 to 2.81 kg (3.6 to 6.2 lb), averaging 2.38 kg (5.2 lb), while females there weigh from 2.28 to 4.2 kg (5.0 to 9.3 lb), averaging 2.95 kg (6.5 lb). Unsurprisingly, adult owls from western Finland were about the same size, averaging 2.65 kg (5.8 lb). Another set of Finnish eagle-owls averaged somewhat larger still, with males averaging 2.64 kg (5.8 lb) and females averaging 3.16 kg (7.0 lb). The subspecies seems to follow Bergmann’s rule in regards to body size decreasing closer to the Equator, as specimens from central Europe average 2.14 or 2.3 kg (4.7 or 5.1 lb) in body mass and those from Italy average about 2.01 kg (4.4 lb). The weight range for eagle-owls in Italy is 1.5 to 3 kg (3.3 to 6.6 lb). The nominate subspecies is perhaps the darkest and most richly coloured of eagle-owl subspecies. Many nominate birds are heavily overlaid with broad black streaking over the upper-parts, head and chest. While generally a brownish base-colour, many nominate owls can appear rich rufous, especially about the head, upper-back and wing primaries. The lower belly is usually a buff brown, as opposed to whitish or yellowish in several other subspecies. Birds seen from southern Italy and Sicily may show a tendency to be smaller than more northern birds and reportedly are duller, possessing paler ground coloration, and more narrow streaks, but museum specimens are often not hugely distinct from north Italian eagle-owls. In Scandinavia, some birds are so darkly plumaged as to give a blackish-brown impression with almost no paler colour showing.
+B. b. hispanus (Rothschild and Hartert, 1910) – Also known as the Spanish eagle-owl or the Iberian eagle-owl. This subspecies mainly occurs on the Iberian Peninsula, where it occupies a majority of Spain and scattered spots in Portugal. B. b. hispanus at least historically occurred in wooded areas of the Atlas Mountains in Algeria, Morocco and Tunisia, making it the only subspecies of Eurasian eagle-owl known to breed in Africa, but this population is thought to be extinct. This is a fairly small-bodied subspecies. In males, wing chord length can range from 40 to 45 cm (16 to 18 in) and in females from 445 to 485 mm (17.5 to 19.1 in). Wingspans in this subspecies can vary from 131 to 168 cm (4 ft 4 in to 5 ft 6 in), averaging about 154.1 cm (5 ft 1 in). Among standard measurements of B. b. hispanus, the tail is 23 to 31 cm (9.1 to 12.2 in), the total bill length is 38.9 to 54.3 mm (1.53 to 2.14 in) and the tarsus is 64.5 to 81 mm (2.54 to 3.19 in). Adult male B. b. hispanus from Spain weigh 1.22 to 1.9 kg (2.7 to 4.2 lb), averaging 1.63 kg (3.6 lb), while females weigh from 1.75 to 2.49 kg (3.9 to 5.5 lb), averaging 2.11 kg (4.7 lb). In terms of its life history, this may be the most extensively studied subspecies of eagle-owl. The Spanish eagle-owl is the most similar in plumage to the nominate subspecies amongst other subspecies, but tends to be a somewhat lighter, more greyish colour, with generally lighter streaking and a paler belly.
+B. b. ruthenus (Buturlin and Zhitkov, 1906) – May be also known as the eastern eagle-owl. This subspecies replaces the nominate in eastern Russia from about latitude 660 N. in the Timan-Pechora Basin south to the western Ural Mountains and the upper Don and lower Volga Rivers. This is a fairly large subspecies going on wing chord length, which is 430–468 mm (16.9–18.4 in) in males and 470–515 mm (18.5–20.3 in) in females. The subspecies is intermediate in coloration between the nominate subspecies and B. b. sibiricus. B. b. ruthenus may be confused with B. b. interpositus, even by authoritative ornithologists. B. b. interpositus is darker than B. b. ruthenus, distinctly more yellowish, less gray, and its brown pattern is darker, heavier, and more regular. The entire colour pattern of B. b. interpositus is brighter, richer, and more contrasting than that of B. b. ruthenus, but B. b. interpositus, though very well characterized, is an intermediate subspecies.
+B. b. interpositus (Rothschild and Hartert, 1910) – May be also known as Aharoni’s eagle-owl or the Byzantine eagle-owl. B. b. interpositus ranges from southern Russia, south of the nominate, with which it intergrades in northern Ukraine, from Bessarabia and the steppes of the Ukraine north to Kyiv and Kharkiv then eastward to the Crimea, the Caucasus and Transcaucasia to northwestern and northern Iran (Elburz, region of Tehran, and probably the southern Caspian districts), and through Asia Minor south to Syria and Iraq but not to the Syrian desert where it is replaced by the pharaoh eagle-owl. The latter and B. b. interpositus reportedly hybridize from western Syria south to southern Palestine. B. b. interpositus may be a distinct species from the Eurasian eagle-owl based on genetic studies. This medium-sized subspecies is about the same size as the nominate subspecies B. b. bubo, with male wing chord lengths 425 to 475 mm (16.7 to 18.7 in) and female lengths of 440 to 503 mm (17.3 to 19.8 in). It differs from the nominate subspecies by being paler and more yellow, less ferruginous, and by having a sharper brown pattern; from B. b. turcomanus by being very much darker and less yellow, and also by being much more sharply and heavily patterned with brown. Aharoni’s eagle-owl is darker and more rusty than B. b. ruthenus.
+B. b. sibiricus (Gloger, 1833) – Also known as the western Siberian eagle-owl. This subspecies is distributed from the Ural Mountains of western Siberia and Bashkiria to the mid Ob River and the western Altai Mountains, north to limits of the taiga, the most northerly distribution known in the species overall. B. b. sibiricus is a large subspecies, wherein the males measure 435–480 mm (17.1–18.9 in) in wing chord length, while the females are 472–515 mm (18.6–20.3 in). Captive males were found to measure 155 to 170 cm (5 ft 1 in to 5 ft 7 in) in wingspan and weigh 1.62 to 3.2 kg (3.6 to 7.1 lb); whereas the females measure 165 to 190 cm (5 ft 5 in to 6 ft 3 in) in wingspan and weigh 2.28 to 4.5 kg (5.0 to 9.9 lb). Males were cited with a mean body mass of approximately 2.5 kg (5.5 lb). This subspecies is physically the most distinctive of all the Eurasian eagle-owls, and is sometimes considered the most "beautiful and striking". It is the most pale of the eagle-owl subspecies; the general coloration is a buffy off-white overlaid with dark markings. The crown, hindneck and underparts are streaked blackish but somewhat sparingly, with the lower breast and belly indistinctly barred, the primary coverts dark, contrasting with rest of the wing. The head, back and shoulders are only somewhat dark unlike in most other subspecies. In the eastern limits of its range, B. b. sibiricus may intergrade with B. b. yenisseensis.
+B. b. yenisseensis (Buturlin, 1911) – Also known as the eastern Siberian eagle-owl. This subspecies is found in central Siberia from about the Ob eastward to Lake Baikal, north to about latitudes 580 to 590 N on the Yenisei River, south to the Altai, Tarbagatai and the Saur Mountain ranges and in Tannu Tuva and Khangai Mountains in northwestern Mongolia, grading into B. b. sibiricus near Tomsk in the west and into B. b. ussuriensis in the east of northern Mongolia. The zone of intergradations with the latter in Mongolia seems to be quite extensive, with intermediate eagle-owls being especially prevalent around the Tuul River Valley, resulting in owls intermediate in coloration between B. b. yenisseensis and B. b. ussuriensis. B. b. yenisseensis is a large subspecies, with wing chord lengths of 435–470 mm (17.1–18.5 in) in males and 473–518 mm (18.6–20.4 in) in females. B. b. yenisseensis is typically much darker with more yellowish ground colour than B. b. sibiricus. It does have a similar amount of dazzling white on its underwing as does sibiricus. It is buffy-greyish overall with well-expressed dark patterning on the upper-parts and around the head. The underside is overall pale greyish with black streaking.
+B. b. jakutensis (Buturlin, 1908) – May be also known as the Yakutian eagle-owl. This subspecies inhabits northeastern Siberia, from southern Yakutia north to about latitude 640 N., west in the basin of the Vilyuy River to the upper Nizhnyaya Tunguska River, and east to the coast of the Sea of Okhotsk from Magadan south to the Khabarovsk Krai. It has been reported farther north, from the regions of the upper Kolyma River and the upper Anadyr. Eurasian eagle-owls are absent in Kamchatka and north of the Verkhoyansk Range. This is a large subspecies, rivaling the proceeding two subspecies as the largest of all eagle-owls, going on wing chord length, which subspecies is largest is unclear considering the extensive size overlap in wing size. The wing chord is 455 to 490 mm (17.9 to 19.3 in) in males and 480 to 503 mm (18.9 to 19.8 in) in females. B. b. jakutensis is much darker and browner above than both B. b. sibiricus and B. b. yenisseensis, though its coloration is more diffused, less sharp than the latter. It is more distinctly streaked and barred below than B. b. sibiricus while being whiter and more heavily vermiculated below than B. b. yenisseensis. This subspecies evidences an almost disheveled, wild appearance suggesting more than other races the fish owl group. B. b. jakutensis has more muted brown and conspicuously elongated feathers, somewhat looser hanging ear tufts and a bulky, large-headed and almost neckless look even for an eagle-owl.
+B. b. ussuriensis (Poljakov, 1915) – Would presumably be also known as the Ussuri eagle-owl. This subspecies ranges from southeastern Siberia, to the south of the range of B. b. jakutensis, southward through eastern Transbaikal, Amurland, Sakhalin, Ussuriland and the Manchurian portion of the Chinese provinces of Shaanxi, Shanxi and Hebei. This subspecies is also reportedly found in the southern Kuril Islands ranging down to as far as northern Hokkaido, the only Japanese representation in the Eurasian eagle-owl species, although this is apparently not a stable, viable population. Going on wing chord length, B. b. ussuriensis is slightly smaller than the various subspecies from further north in Siberia. Males have a wing chord length of 430–475 mm (16.9–18.7 in) and females are 460–502 mm (18.1–19.8 in). This subspecies differs from B. b. jakutensis by being much darker throughout. It is also darker than B. b. yenisseensis. The brown markings on the upper parts of B. b. ussuriensis are much more extensive and diffused than in B. b. jakutensis or B. b. yenisseensis, with the result that the white markings are much less conspicuous in B. b. ussuriensis than in the other two subspecies. The under parts are also more buffy, much less white, and more heavily streaked and vermiculated in B. b. ussuriensis than in the two more northerly, larger subspecies. It overlaps considerably with jakutensis and some birds are of an intermediate appearance.
+B. b. turcomanus (Eversmann, 1835) – Also known as the steppe eagle-owl. It is distributed from Kazakhstan between the Volga and upper Ural Rivers, the Caspian Sea coast and the former Aral Sea, but replaced in that country by B. b. omissus in the mountainous south and in the coastal region of the Mangyshlak Peninsula by B. b. gladkovi. Out of Kazakhstan, the range of B. b. turcomanus continues through the Transbaikal and the Tarim Basin to western Mongolia. This subspecies appears to be variable in size, but is generally medium-sized. Males can range in wing chord length from 418–468 mm (16.5–18.4 in) and females from 440 to 512 mm (17.3 to 20.2 in). In standard measurements, the tail is 260–310 mm (10–12 in), the tarsus is 77–81 mm (3.0–3.2 in) and the bill is 45–47 mm (1.8–1.9 in). This subspecies can reportedly weigh from 1.5 to 3.8 kg (3.3 to 8.4 lb). The plumage background colour is pale, yellowish-buff. The dark patterns on the upper- and underparts is paler, less well-defined and more shattered than in B. b. interpositus. Dark longitudinal patterning on the under-parts discontinue above the belly. B. b. turcomanus is greyer than B. b. hemalachanus but is otherwise somewhat similar-looking. This subspecies is unique in that it seems to shun mountainous and obvious rocky habitats in favor of low hills, plateaus, lowlands, steppes, and semideserts at or near sea-level.B. b. omissus (Dementiev, 1932) – May be also known as the Turkoman eagle-owl or the Turkmenian eagle-owl. B. b. omissus is native to Turkmenistan and adjacent regions of northeastern Iran and western Xinjiang. This is a small subspecies (only nikolskii averages smaller among currently accepted races), with males possessing a wing chord length of 404–450 mm (15.9–17.7 in) and females of 425 to 460 mm (16.7 to 18.1 in). B. b. omissus may be considered a typical sub-desert form. The general coloration is an ochre to buffy off-yellow; with the dark pattern on the upper- and under-parts being relatively undefined. The dark shaft-streaks on nape are very narrow, while the dark longitudinal patterning on the underparts does not cover the belly. A dark cross-pattern on the belly and flanks is thinner and paler than in B. b. turcomanus and some individuals may appear almost all pale below. Compared to B. b. nikolskii, which may occupy the more southern reaches of the same upland ranges, it is somewhat larger as well as darker, less distinctly yellowish and more heavily streaked.
+B. b. nikolskii (Zarudny, 1905) – May be also known in English as either the Afghan eagle-owl or the Iranian eagle-owl. The range of B. b. nikolskii appears to extend from the Balkan Mountains and Kopet Dagh in southern Transcaspia eastward to southeastern Uzbekistan or to perhaps southwestern Tadzhikistan, then southward 290 N. It may range north to Iran, Afghanistan and Baluchistan south to the region of Kalat, or at about latitude of Hindu Kush. In Iran, B. b. nikolskii is replaced by B. b. interpositus in the north, and probably also in the northwest, and probably by B. b. hemalachana in Badakhshan, part of northeastern Afghanistan. The birds of southern Tadzhikistan found west of the Pamirs are more or less intermediate between B. b. omissus and B. b. hemachalana. This is the smallest known subspecies of eagle-owl, though the only known measurements have been of wing chord length. Males can measure 378 to 430 mm (14.9 to 16.9 in) and females can measure 410 to 465 mm (16.1 to 18.3 in) in wing chord. Other than its smaller size, B. b. nikolskii is distinguished from the somewhat similar B. b. omissus by its rusty wash and being less dark above.
+B. b. hemachalana (Hume, 1873) – Also known as the Himalayan eagle-owl. The range of B. b. hemachalana extends from the Himalayas, from Pakistan through Jammu and Kashmir and Ladakh to at least Bhutan, also living in Tibet. Its range continues also westward to the Tian Shan system in Russian Turkestan, west to the Karatau, north to the Dzungarian Alatau, east to at least the Tekkes Valley in Xinjiang, and south to the regions of Kashgar, Yarkant and probably the western Kunlun Mountains. This bird is partly migratory, descending to the plains of Turkmenistan with colder winter weather, and apparently reaches northern Balochistan. This is a medium-sized subspecies, though it is larger than other potentially abutting arid Asian eagle-owl subspecies, which share a somewhat similar yellowish ground colour. The male attains a wing chord length of 420–485 mm (16.5–19.1 in), while the female’s wing chord is 450–505 mm (17.7–19.9 in). The bill measures 4.2–4.5 cm (1.7–1.8 in) in length. 11 adult eagle-owls of the subspecies from the Tibetan Plateau averaged 301 mm (11.9 in) in tail length, 78 mm (3.1 in) in tarsus length and scaled an average of 2.16 kg (4.8 lb) in mass. This subspecies is physically similar to B. b. turcomanus but the background colour is more light yellowish-brown and less buff. The dark patterns on the upperparts and underparts are more expressed and less regular than in B. b. turcomanus and B. b. omissus and the general colour from the mantle to the ear tufts is a more consistent brownish colour than most other abutting races. B. b. hemachalana differs from B. b. yenisseensis by being much more yellow on the rump, under tail coverts, and outer tail feathers, rather than grayish or whitish, and the ground coloration of its body is more yellowish above, and is less whitish below. Dark longitudinal pattern on the under-parts cover the forebelly.
+B. b. kiautschensis (Reichenow, 1903) – This subspecies could be also known as the North Chinese eagle-owl. It ranges from South Korea and China, south of the range of B. b. ussuriensis, southward to Kwangtung and Yunnan, and inland to Szechwan and southern Kansu. This is a smallish subspecies, with the male’s wing chord measuring 410–448 mm (16.1–17.6 in) and the female’s being 440–485 mm (17.3–19.1 in). In Korea, this subspecies was found to average 2.26 kg (5.0 lb) in mass, with a range of 1.8 to 2.9 kg (4.0 to 6.4 lb). B. b. kiautschensis is much darker, more tawny and rufous, and slightly smaller than B. b. ussuriensis. According to museum accounts, it resembles the nominate subspecies from Europe (though obviously considerably disparate in distribution) rather closely in coloration but differs from it by being paler, more mottled, and less heavily marked with brown on the upper parts, by having narrower dark shaft streaks on the under parts, which average also duller and more ocher, and by averaging smaller. Images from South Korea of captive and wild owls show, on the contrary, that this race may be easily as darkly marked as most nominate eagle-owls with a more rufous base colour altogether suggesting a richer and more dusky-colored eagle-owl than from almost any other population.
+B. b. swinhoei (Hartert, 1913) – This subspecies could be also known as the South Chinese eagle-owl. It is endemic to southeastern China. A quite rufescent form, it is somewhat similar to B. b. kiautschensis. In this smallish subspecies, the wing chord measures 41–46.5 cm (16.1–18.3 in) in both sexes. This is a rather poorly known and described subspecies and is considered invalid by some authorities.

+
+== Habitat ==
+
+Eagle-owls are distributed somewhat sparsely, but can potentially inhabit a wide range of habitats, with a partiality for irregular topography. They have been found in habitats as diverse as northern coniferous forests to the edge of vast deserts. Essentially, Eurasian eagle-owls have been found living in almost every climatic and environmental condition on the Eurasian continent, excluding the greatest extremities, i.e. they are absent from humid rainforest in Southeast Asia, and the high Arctic tundra, both of which they are more or less replaced by other species of Bubo owls. They are often found in the largest numbers in areas where cliffs and ravines are surrounded by a scattering of trees and bushes. Grassland areas such as alpine meadows or desert-like steppe can also host them so long as they have the cover and protection of rocky areas. The preference of eagle-owls for places with irregular topography has been reported in most known studies. The obvious benefit of such nesting locations is that both nests and daytime roosts located in rocky areas and/or steep slopes would be less accessible to predators, including man. Also, they may be attracted to the vicinity of riparian or wetlands areas, because the soft soil of wet areas is conducive to burrowing by the small, terrestrial mammals normally preferred in the diet, such as voles and rabbits.Due to their preference for rocky areas, the species is often found in mountainous areas, and can be found up to elevations of 2,100 m (6,900 ft) in the Alps, 4,500 m (14,800 ft) in the Himalayas, and 4,700 m (15,400 ft) in the adjacent Tibetan Plateau. They can also be found living at sea level and may nest amongst rocky sea cliffs. Despite their success in areas such as subarctic zones and mountains that are frigid for much of the year, warmer conditions seem to result in more successful breeding attempts per studies in the Eifel region of Germany. In a study from Spain, areas primarily consisting of woodlands (52% of study area being forested) were preferred with pine trees predominating the oaks in habitats used, as opposed to truly mixed pine-oak woodland. Pine and other coniferous stands are often preferred in great horned owls, as well, due to the constant density, which make  overlooking the large birds more likely. In mountainous forest, they are not generally found in enclosed wooded areas, as is the tawny owl (Strix alucco), instead usually near forest edge. Only 2.7% of the habitat included in the territorial ranges for eagle-owls per the habitat study in Spain consisted of cultivated or agricultural land. Compared to golden eagles, though, they can visit cultivated land more regularly in hunting forays due to their nocturnal habits, which allow them to largely evade human activity. Other accounts make clear that farmland is only frequented where its less intensively farmed, holds more extensive treed and bushy areas, and often has limited to no irrigation; farmland areas with fallow or abandoned fields are more likely to hold
+more prey, so are prone to less frequent human disturbance. In the Italian Alps, almost no pristine habitat remained, and eagle-owls nested locally in the vicinity of towns, villages, and ski resorts.
+
+Although found in the largest numbers in areas sparsely populated by humans, farmland is sometimes inhabited, and they even have been observed living in park-like or other quiet settings within European cities. Since 2005, at least five pairs have nested in Helsinki. This is due in part to feral European rabbits (Oryctolagus cuniculus) having recently populated the Helsinki area, originally from pet rabbits released to the wild. The number is expected to increase due to the growth of the European rabbit population in Helsinki. European hares (Lepus europaeus), the often preferred prey species by biomass of the eagle-owls in their natural habitat, live only in rural areas of Finland, not in the city centre. In June 2007, an eagle-owl nicknamed 'Bubi' landed in the crowded Helsinki Olympic Stadium during the European Football Championship qualification match between Finland and Belgium. The match was interrupted for six minutes. After tiring of the match, following Jonathan Johansson's opening goal for Finland, the bird left the scene. Finland's national football team have had the nickname Huuhkajat (Finnish for "Eurasian eagle-owls") ever since. The owl was named "Helsinki Citizen of the Year" in December 2007. In 2020, a brood of three eagle-owl chicks was raised by their mother on a large, well-foliaged planter on an apartment window in the city centre of Geel, Belgium.
+
+
+== Distribution ==
+The Eurasian eagle-owl is one of the most widely distributed of all owl species, although it is far less wide-ranging than the barn owl, the short-eared owl (Asio flammeus) and long-eared owl and lacks the circumpolar range of boreal species such as great grey owl, boreal owl and northern hawk owl (Surnia ulula). This eagle-owl reaches its westernmost range in the Iberian peninsula, both almost throughout Spain and more spottily in Portugal. From there, the Eurasian eagle-owl ranges widely in the south of France from Toulouse to Monaco and as far north into the central part of the country as in Allier. Farther north, they are found sporadically and discontinuously in Luxembourg, southern and western Belgium and scarcely into the Netherlands. It is infrequently found in southern and central United Kingdom. In Germany, the eagle-owl can be found in large but highly discontinuous areas, mostly in the south and central areas but is almost entirely absent in areas such as Brandenburg. Across from its south German range, this species range is nearly continuous into the Czech Republic, Slovakia, northern and eastern Hungary and very spottily into Poland. In the fairly montane countries of Switzerland and Austria, the eagle-owl can be found fairly broadly. In Italy, the Eurasian eagle-owl is found where the habitat is favorable in much of the northern, western and central portions down to as far south Melito di Porto Salvo. From Italy, this species sweeps quite broadly along the Mediterranean coast in Southeastern Europe from Slovenia mostly continuously to most of Greece and Bulgaria. In eastern Europe, the Eurasian eagle-owl is found essentially throughout from central Romania to Estonia. The species also occupies a majority of Scandinavia, most broadly  in Norway and subarctic Finland (more spottily in Sweden) and much of Denmark.The Eurasian eagle-owl's range in Russia is truly massive, with the species apparently nearly unbound by habitat, with their distribution only excluding them from the true Arctic zone, i.e. their range stops around the tree line. If not the most densely populated species, they almost certainly stand as Russia's most widely distributed owl species. From Russia, they are found throughout Central Asia, residing continuously in each nation from Kazakhstan down to Afghanistan. In Asia Minor, they are found broadly in Georgia, Azerbaijan and somewhat so in western and southern Turkey but is quite sporadic in distribution overall in Turkey. A spotty range also exists in the Middle East in Syria, Iraq, Lebanon, Israel, Jordan and western Iran, the species being found broadly only in north and western Iran. In South Asia, the Eurasian eagle-owl is found mostly often in northern Pakistan, northern Nepal and Bhutan and more marginally into far northern India. This species resides throughout Mongolia, almost the entirety of China (mainly absent only from southern Yunnan and southern Guangxi). From China and eastern Russia, the Eurasian eagle-owl is found throughout Korea, Sakhalin, the Kuril Islands and rarely into Japan in northern Hokkaido. Besides the Kurils, the farthest eastern part of the range for this species is in Magadan in the Russian Far East.
+
+
+== Behaviour ==
+
+The Eurasian eagle-owl is largely nocturnal in activity, as are most owl species, with its activity focused in the first few hours after sunset and the last few hours before sunrise. In the northern stretches of its range, partial diurnal behaviour has been recorded, including active hunting in broad daylight during the late afternoon. In such areas, full nightfall is essentially non-existent at the peak of summer, so eagle-owls must presumably hunt and actively brood at the nest during daylight. The Eurasian eagle-owl has a number of vocalizations that are used at different times. It will usually select obvious topographic features such as rocky pinnacles, stark ridges and mountain peaks to use as regular song posts. These are dotted along the outer edges of the eagle-owl's territory and they are visited often but only for a few minutes at a time.Vocal activity is almost entirely confined to the colder months from late fall through winter, with vocal activity in October through December mainly having territorial purposes and from January to February being primarily oriented towards courtship and mating purposes. Vocalizations in a Spanish study begin no sooner than 29 minutes after sunset and end no later than 55 minutes before sunrise. The territorial song, which can be heard at great distance, is a deep resonant ooh-hu with emphasis on the first syllable for the male, and a more high-pitched and slightly more drawn-out uh-hu for the female. It is not uncommon for a pair to perform an antiphonal duet. The widely used name in Germany as well as some other sections of Europe for this species is uhu due to its song. At 250–350 Hz, the Eurasian eagle-owls territorial song or call is deeper, farther-carrying and is often considering "more impressive" than the territorial songs of the great horned owl or even that of the slightly larger Blakiston's fish owl, although the horned owl’s call averages slightly longer in duration. Other calls include a rather faint, laughter-like OO-OO-oo and a harsh kveck-kveck. Intruding eagle-owls and other potential dangers may be met with a "terrifying", extremely loud hooo. Raucous barks not unlike those of ural owls or long-eared owls have been recorded but are deeper and more powerful than those species’ barks. Annoyance at close quarters is expressed by bill-clicking and cat-like spitting, and a defensive posture involves lowering the head, ruffling the back feathers, fanning the tail and spreading the wings.
+
+The Eurasian eagle-owl rarely assumes the so-called "tall-thin position", which is when an owl adopts an upright stance with plumage closely compressed and may stand tightly beside a tree trunk. Among others, the long-eared owl is among the most often reported to sit with this pose. The great horned owl has been more regularly recorded using the tall-thin, if not as consistently as some Strix and Asio owls, and it is commonly thought to aid camouflage if encountering a threatening or novel animal or sound. The Eurasian eagle-owl is a broad-winged species and engages in a strong, direct flight, usually consisting of shallow wing beats and long, surprisingly fast glides. It has, unusually for an owl, also been known to soar on updrafts on rare occasions. The latter method of flight has led them to be mistaken for Buteos, which are smaller and quite differently proportioned. Usually when seen flying during the day, it is due to being disturbed or displaced from its roost by humans or mobbing animals, such as crows. Eurasian eagle-owls are highly sedentary, normally maintaining a single territory throughout their adult lives.
+Eurasian eagle-owl are considered a completely non-migratory bird, as are all members of the Bubo genus excluding the snowy owl. Even those near the northern limits of their range, where winters are harsh and likely to bear little in food, the eagle-owl does not leave its native range. In 2020, a study presented evidence of a short distance distribution by adult eagle-owls in the fall subsequent to breeding, with 5 adults found to move over 20 km (12 mi) away from their nests. There are additionally claimed cases from Russia of Eurasian eagle-owls moving south for the winter, as the icebound, infamously harsh climate there may be too severe even for these hardy birds and their prey. Similarly, Eurasian eagle-owls living in the Tibetan highlands and Himalayas may in some ancedotal cases vacate their normal territories when winter hits and move south. In both of those examples, these are old, unverified reports and there is no evidence whatsoever of consistent, annual migration by Eurasian eagle-owls and the birds may eke out a living on their normal territories even in the sparsest times.

+
+=== Territoriality ===
+Eurasian eagle-owls are strictly territorial and will defend their territories from interloping eagle-owls year around, but territorial calling appears to peak around October to early January. Territory size is similar or occasionally slightly greater than great horned owl: averaging 15 to 80 km2 (5.8 to 30.9 sq mi). Territories are established by the male eagle-owl, who selected the highest points in the territory from which to sing. The high prominence of singing perches allows their song to be heard at greater distances and lessens the need for potentially dangerous physical confrontations in the areas where territories may meet. Nearly as important in territorial behaviour as vocalization is the white throat patch. When taxidermied specimens with flared white throats were placed around the perimeter of eagle-owl territories, male eagle-owls reacted quite strongly and often attacked the stuffed owl, reacting more mildly to a stuffed eagle-owl with a non-flared white throat. Females were less likely to be aggressive to mounted specimens and did not seem to vary in their response whether exposed to the specimens with or without the puffed up white patch. In January and February, the primary function for vocalization becomes for the purpose of courtship. More often than not, eagle-owls will pair for life but usually engage in courtship rituals annually, most likely to re-affirm pair bonds. When calling for the purposes of courtship, males tend to bow and hoot loudly but do so in a less contorted manner than the male great horned owl. Courtship in the Eurasian eagle-owl may involve bouts of "duetting", with the male sitting upright and the female bowing as she calls. There may be mutual bowing, billing and fondling before the female flies to a perch where coitus occurs, usually taking place several times over the course of a few minutes.
+
+
+=== Nests ===
+
+The male selects breeding sites and advertises their potential to the female by flying to them and kneading out a small depression (if soil is present) and making staccato notes and clucking noises. Several potential sites may be presented, with the female selecting one. In Baden-Wurttenberg, Germany, the amount of male nest site visits were found to increase in time spent over the pre-laying breeding season from a mean of 29 minutes to 3 hours with frequent incubation like sitting by the male. Like all owls, Eurasian eagle-owls do not build nests or add material but nest on the surface or material already present. Eurasian eagle-owls normally nest on rocks or boulders, most often utilizing cliff ledges and steep slopes, as well as crevices, gullies, holes or caves. Rocky areas that also prove concealing woodlots as well as, for hunting purposes, that border river valleys and grassy scrubland may be especially attractive. If only low rubble is present, they will nest on the ground between rocks. Often, in more densely forested areas, they've been recorded nesting on the ground, often among roots of trees, under large bushes and under fallen tree trunks. Steep slopes with dense vegetation are preferred if nesting on the ground, although some ground nests are surprisingly exposed or in flat spots such as in open spots of the taiga, steppe, ledges of river banks and between wide tree trunks. All Eurasian eagle-owl nests in the largely forested Altai Krai region of Russia were found to be on the ground, usually at the base of pines. This species does not often use other bird’s nests as does the great horned owl, which often prefers nests built by other animals over any other nesting site. The Eurasian eagle-owl has been recorded in singular cases using nests built by common buzzards (Buteo buteo), golden eagle, greater spotted (Clanga clanga) and white-tailed eagles (Haliaeetus albicilla), common ravens (Corvus corax) and black storks (Ciconia nigra). Among the eagle-owls of the fairly heavily wooded wildlands of Belarus, they more commonly utilize nests built by other birds than most eagle-owls, i.e. stork or accipitrid nests, but a majority of nests are still located on the ground. This is contrary to the indication that ground nests are selected only if rocky areas or other bird nests are unavailable, as many will utilize ground nests even where large bird nests seem to be accessible. Tree holes being used for nesting sites are even more rarely recorded than nests constructed by other birds. While it may be assumed that the eagle-owl is too large to utilize tree hollows, when other large species like the great grey owl have never been recorded nesting in one, the even more robust Blakiston's fish owl nests exclusively in cavernous hollows. The Eurasian eagle-owl often uses the same nest site year after year.
+
+
+=== Parental behaviour ===
+
+In Engadin, Switzerland, the male eagle-owl hunts until the young are 4 to 5 weeks old and the female spends all her time brooding at the nest. After this point, the female gradually resumes hunting from both herself and the young and thus provides a greater range of food for the young. While it may seem contrary to the species’ highly territorial nature, there is one verified cases of polygamy in Germany, with a male apparently mating with two females, and cooperative brooding in Spain, with a third adult of undetermined sex helping a breeding pair care for the chicks. The response of Eurasian eagle-owls to humans approaching at the nest is quite variable. The species is often rather less aggressive than some other owls, including related species like the spot-bellied eagle-, great horned and snowy owls, many of the northern Strix species and even some rather smaller owl species, which often fearlessly attack any person found to be nearing their nests. Occasionally, if a person climbs to an active nest, the adult female eagle-owl will do a distraction display, in which they feign an injury. This is an uncommon behaviour in most owls and most often associated with small birds trying to falsely drawl the attention of potential predators away from their offspring. More commonly, the female flies off and abandons her nest temporarily, leaving the eggs or small nestlings exposed, when a human approaches it. Occasionally, if cornered both adults and nestlings will do an elaborate threat display, also rare in owls in general, in which the eagle-owls raise their wings into a semi-circle and puff up their feathers, followed by a snapping of their bills. Apparently eagle-owls of uncertain and probably exotic origin in Britain are likely to react aggressively to humans approaching the nest. Also, aggressive encounters involving eagle-owls around their nest, despite being historically rare, apparently have increased in recent decades in Scandinavia. The discrepancy of aggressiveness at the nest between the Eurasian eagle-owl and its Nearctic counterpart may be correlated to variation in the extent of nest predation that the species endured during the evolutionary process.
+
+
+=== Eggs and offspring development ===
+
+The eggs are normally laid at intervals of three days and are incubated only by the female. Laying generally begins in late winter but may be later in the year in colder habitats. During the incubation period, the female is brought food at the nest by her mate. A single clutch of white eggs is laid; each egg can measure from 56 to 73 mm (2.2 to 2.9 in) long by 44.2 to 53 mm (1.74 to 2.09 in) in width, and will usually weigh about 75 to 80 g (2.6 to 2.8 oz). In Central Europe, eggs average 59.8 mm × 49.5 mm (2.35 in × 1.95 in), and in Siberia, eggs average 59.4 mm × 50.1 mm (2.34 in × 1.97 in). Their eggs are only slightly larger than those of snowy owls and the nominate subspecies of great horned owl, while similar in size to those of spot-bellied eagle-owls and Blakiston's fish owls. The Eurasian eagle-owl’s eggs are noticeably larger than those of Indian eagle-owl and pharaoh eagle-owls. Usually clutch size is one or two, rarely three or four, and exceptionally to six. The average number of eggs laid varies with latitude in Europe. Clutch size ranges from 2.02 to 2.14 in Spain and the massifs of France, and 1.82 to 1.89 in central Europe and the eastern Alps; in Sweden and Finland, the mean clutch size is 1.56 and 1.87, respectively. While variation based on climate is not unusual for different wide-ranging palearctic species, the higher clutch size of western Mediterranean eagle-owls is also probably driven by the presence of lagomorphs in the diet, which provide high nutritional value than most other regular prey. The average clutch size, attributed as 2.7, was the lowest of any European owl per one study. One species was attributed with an even lower clutch size in North America, the great grey owl with a mean of 2.6, but the mean clutch size was much higher for the same species in Europe, at 4.05.In Spain, incubation is from mid-January to mid-March, hatching and early nestling period is from late March to early April, fledging and postfledging dependence can range from mid-April to August, and territorial/courtship is anytime hereafter; i.e. the period between the beginning of juvenile dispersal to egg laying; from September to early January. The same general date parameters were followed in southern France. In the Italian Alps, the mean egg-laying date was similarly February 27, but the young were more likely to be dependent later, as all fledglings were still being cared for by the end of August, and some even lingered under parental care until October. In northern climes, the breeding season shifts somewhat later by as much as a month so that egg laying may be as late as late March or early April. Nonetheless, the Eurasian eagle-owl is one of the earliest nesting bird species in Europe or northern, temperate Asia.The first egg hatches after 31 to 36 days of incubation. The eggs hatch successively; although the average interval between egg-laying is 3 days, the young tend to hatch no more than a day or two apart. Like all owls that nest in the open, the downy young are often a mottled grey with some white and buff, which provides camouflage. They open their eyes at 4 days of age. The chicks grow rapidly, being able to consume small prey whole after roughly 3 weeks. In Andalusia, the most noticeable development of the young before they leave the nest was the increase of body size, which was the highest growth rate of any studied owl and faster than either snowy or great horned owls. Body mass increased fourteen times over from 5 days old to 60 days old in this study. The male continues to bring prey, leaving it on or around the nest, and the female feeds the nestlings, tearing up the food into suitably sized pieces. The female resumes hunting after about 3 weeks, which increases the food supply to the chicks. Siblicide has been recorded widely in Eurasian eagle-owls, and according to some authorities, is almost a rule in the species. Many nesting attempts produce two fledglings, indicating that siblicide is not as common as in other birds of prey, especially some eagles. In Spain, males are thought to be the first egg laid to reduce the likelihood of sibling aggression due to the size difference, thus the younger female hatchling is less likely to be killed, since it is similar in size to its older sibling.Apparently, the point at which the chicks venture out of the nest is driven by the location of the nest. In elevated nest sites, chicks usually wander out of the nest at 5 to as late as 7 weeks of age, but have been recorded leaving the nest if the nest is on the ground as early as 22 to 25 days old. The chicks can walk well at 5 weeks of age and by 7 weeks are taking short flights. Hunting and flying skills are not tested prior to the young eagle-owls leaving the nest. Young Eurasian eagle-owls leave the nest by 5–6 weeks of age and typically can be flying weakly (a few metres) by about 7–8 weeks of age. Normally, they are cared for at least another month. By the end of the month, the young eagle-owls are quite assured fliers. A few cases have been confirmed of adult eagle-owls in Spain feeding and caring for postfledgling juvenile eagle-owls that were not their own.
+
+A study from southern France found the mean number of fledglings per nest was 1.67. In central Europe, the mean number of fledglings per nest was between 1.8 and 1.9. The mean fledgling rate in the Italian Alps was 1.89, thus being similar. In the Italian Alps, heavier rainfall during breeding decreased fledgling success because it inhibited the ability of the parents to hunt and potentially exposed nestlings to hypothermia. In the reintroduced population of eagle-owls in Eifel, Germany, occupied territories produced an average of 1.17 fledglings, but not all occupying pairs attempted to breed, with about 23% of those attempting to breed being unsuccessful. In slightly earlier studies, possibly due to higher persecution rates, the mean number of young leaving the nest was often lower, such as 1.77 in Bavaria, Germany, 1.1 in lower Austria, and 0.6 in southern Sweden. An experimental supplemental feeding program to young eagle-owls on two small Norwegian islands were found to increase mean numbers of fledglings from a mean of about 1.2 to 1.7 despite evidence that increased human activity near the nest decreased owlet survivability. While sibling owls are close in the stage between leaving the nest and fully fledged, about 20 days after leaving the nest, the family unit seems to dissolve and the young disperse quickly and directly. All told, the dependence of young eagle-owls on their parents lasts for 20 to 24 weeks. Independence in central Europe is from September to November. The young leave their parents' care normally on their own, but are also sometimes chased away by their parents. The young Eurasian eagle-owls reach sexual maturity by the following year, but do not normally breed until they can establish a territory at around 2–3 years old. Until they are able to establish their own territories, young eagle-owls spend their lives as nomadic "floaters", and while they also call, select inconspicuous perch sites unlike breeding birds. Male floaters are especially wary about intrusion into an established territory to avoid potential conspecific aggression.
+
+
+== Status ==
+
+The Eurasian eagle-owl has a very wide range across much of Europe and Asia, estimated to be about 32,000,000 km2 (12,000,000 sq mi). In Europe, the population is estimated at 19,000 to 38,000 breeding pairs, and in the whole world around 250,000 to 2,500,000 individual birds. The population trend is thought to be decreasing because of human activities, but with such a large range and large total population, the International Union for Conservation of Nature has rated the bird as being of least concern. Although roughly equal in adaptability and wideness of distribution, the great horned owl, with a total estimated population up to 5.3 million individuals, apparently has a total population that is roughly twice that of the Eurasian eagle-owl. Numerous factors, including a shorter history of systematic persecution, lesser sensitivity to human disturbance while nesting, somewhat greater ability to adapt to marginal habitats and widespread urbanization, and slightly smaller territories may play into the horned owls greater numbers in modern times. Eurasian eagle-owls are listed in Appendix II of the Convention on International Trade in Endangered Species (CITES) meaning international trade (including in parts and derivatives) is regulated.
+
+
+=== Longevity ===
+The Eurasian eagle-owl surely is one of the longest-living owls on average. The eagle-owl can live for up to 20 years in the wild. At one time, the oldest ringed eagle-owl was considered a 19-year-old specimen. Some studies posited that in protected areas, lifespans ranging up to 15–20 years may not be uncommon. A record-breaking specimen banded in the wild was subsequently found to survive to be 27 years and 9 months old. Like many other bird species in captivity, they can live much longer without having to endure difficult natural conditions, and have possibly survived up to 68 years in zoo collections. Healthy adults normally have no natural predators, thus are considered apex predators. The leading causes of death for this species are man-made; electrocution, traffic accidents, and shooting frequently claim the lives of eagle-owls.
+
+
+=== Anthropogenic mortality ===
+Electrocution was the greatest cause of mortality in 68% of 25 published studies, and accounted, on average, for 38.2% of the reported eagle-owl deaths. This was particularly true in the Italian Alps, where the number of dangerous, uninsulated pylons near nests was extremely high, but is highly problematic almost throughout the species’ European distribution. In one telemetry study, 55% of 27 dispersing young were electrocuted within 1 year of their release from captivity, while electrocution rates of wild-born young are even higher. Mortality in the Swiss Rhine Valley was variable, in radio-tagged, released individuals, most died as a result of starvation (48%) rather than human-based causes, but 93% of the wild, untagged individuals found dead were due to human activities, 46% due to electrocution, and 43% due to collision with vehicles or trains. Insulation of pylons is thought to result in a stabilisation of the local population due to floaters taking up residence in unoccupied territories that formerly held deceased eagle-owls. Eurasian eagle-owls from Finland were found mainly to die due to electrocution (39%) and collisions with vehicles (22%). Wind turbine collisions can also be a serious cause of mortality locally.Eagle-owls have been singled out historically as a threat to game species, thus to the economic well-being of landowners, game-keepers, and even governmental agencies, and as such, have been singled out for widespread persecution. Local extinctions of Eurasian eagle-owls have been primarily due to persecution. Examples of this include northern Germany in 1830, the Netherlands sometimes in the late 19th century, Luxembourg in 1903, Belgium in 1943, and central and western Germany in the 1960s. In trying to determine causes of death for 1476 eagle-owls from Spain, most were unknown and undetermined types of trauma. The largest group that could be determined, 411 birds, was due to collisions, more than half of which were from electrocution, while 313 were due to persecution, and merely 85 were directly attributable to natural causes. Clearly, while pylon safety is perhaps the most serious factor to be addressed in Spain, persecution continues to be a massive problem for Spanish eagle-owls. Of seven European nations where modern Eurasian eagle-owl mortality is well-studied, continual persecution is by far the largest problem in Spain, although also continues to be serious (often comprising at least half of studied mortality) in France. From France and Spain, nearly equal numbers of eagle-owls are poisoned (for which raptors might not be the main target), or shot intentionally.
+
+
+=== Conservation and reintroductions ===
+
+While the eagle-owl remains reasonably numerous in some parts of its habitat where nature is still relatively little disturbed by human activity, such as the sparsely populated regions of Russia and Scandinavia, concern has been expressed about the future of the Eurasian eagle-owl in Western and Central Europe. There, very few areas are not heavily modified by human civilisation, thus exposing the birds to the risk of collisions with deadly man-made objects (e.g. pylons) and a depletion of native prey numbers due to ongoing habitat degradation and urbanisation.In Spain, long-term governmental protection of the Eurasian eagle-owl seems to have no positive effect on reducing the persecution of eagle-owls. Therefore, Spanish conservationists have recommended to boost education and stewardship programs to protect eagle-owls from direct killing by local residents. Unanimously, biologists studying eagle-owl mortality and conservation factors have recommended to proceed with the proper insulation of electric wires and pylons in areas where the species is present. As this measure is labour-intensive and therefore rather expensive, few efforts have actually been made to insulate pylons in areas with few fiscal resources devoted to conservation such as rural Spain. In Sweden, a mitigation project was launched to insulate transformers that are frequently damaged by eagle-owl electrocution.Large reintroduction programs were instituted in Germany after the eagle-owl was deemed extinct in the country as a breeding species by the 1960s, as a result of a long period of heavy persecution. The largest reintroduction there occurred from the 1970s to the 1990s in the Eifel region, near the border with Belgium and Luxembourg. The success of this measure, consisting in more than a thousand eagle-owls being reintroduced at an average cost of US$1,500 per bird, is a subject of controversy. Those eagle-owls reintroduced in the Eifel region appear to be able to breed successfully, and enjoy nesting success comparable with wild eagle-owls from elsewhere in Europe. Mortality levels in the Eifel region, though, appear to remain quite high due to anthropogenic factors. Also, concerns exist about a lack of genetic diversity of the species in this part of Germany. Apparently, the German reintroductions have allowed eagle-owls to repopulate neighbouring parts of Europe, as the breeding populations now occurring in the Low Countries (the Netherlands, Belgium, and Luxembourg) are believed to be the result of influx from regions further to the east. Smaller reintroductions have been done elsewhere, and the current breeding population in Sweden is believed to be primarily the result of a series of reintroductions. Conversely to numerous threats and declines incurred by Eurasian eagle-owls, areas where human-dependent, non-native prey species such as brown rats (Rattus norvegicus) and rock pigeons (Columba livia) have flourished, have given the eagle-owls a primary food source and allowed them occupy regions where they were once marginalized or absent.
+
+
+=== Occurrence in Great Britain ===
+The Eurasian eagle-owl at one time occurred naturally in Great Britain. Some, including the RSPB, have claimed that it had disappeared about 10,000–9,000 years ago, after the last ice age, but fossil remains found in Meare Lake Village indicate the eagle-owl occurring as recently as roughly 2,000 years ago in the fossil record. The lack of presence of the Eurasian eagle-owl in British folklore or writings in recent millennium may indicate the lack of occurrence by this species there. The flooding of the land bridge between Britain and continental Europe may have been responsible for their extirpation as they only disperse over limited distances, although early human persecution presumably played a role as well. Some reportages of eagle-owls in Britain have been revealed to actually be great horned owls or Indian eagle-owls, the latter a particularly popular owl in falconry circuits. Some breeding pairs do still occur in Britain, though the exact number of pairs and individuals is not definitely known. The World Owl Trust stated that they believe some eagle-owls occurring in North England and Scotland are naturally occurring, making the flight of roughly 350 to 400 km (220 to 250 mi) from the west coast of Norway to Shetland and the east coast of Scotland, as well as possibly from the coasts of the Netherlands and Belgium to the south. Although not migratory, eagle-owls can disperse some notable distances in young birds seeking a territory.Prior studies of eagle-owl distribution have indicated a strong reluctance to cross large bodies of water in the species. Many authorities state that the Eurasian eagle-owls occurring in Britain are individuals that have escaped from captivity. While, until the 19th century, wealthy collectors may have released unwanted eagle-owls, despite press to the contrary,  no evidence of any organization or individual intentionally releasing eagle-owls recently with the intent to establish a breeding population has been found. Many feel that the eagle-owl would be classified as an "alien" species. Due to its predatory abilities, many, especially those in the press, have expressed alarm of their effect on "native" species. From 1994 to 2007, 73 escaped eagle-owls were not registered as returned, while 50 escapees were recaptured. Several recorded breeding attempts have been studied, and most were unsuccessful, due in large part to incidental disturbance by humans and some due to direct persecution, with eggs having been smashed.
+
+
+=== Effect on conservation-dependent species ===
+As highly opportunistic predators,  Eurasian eagle-owls hunt almost any appropriately sized prey they encounter. Most often, they take whatever prey is locally common and can take a large number of species considered harmful to human financial interests, such as rats, mice, and pigeons. Eurasian eagle-owls do take rare or endangered species, as well. Among the species considered at least vulnerable (up to critically endangered as in the mink and eel, both heavily overexploited by humans) to extinction known to be hunted by Eurasian eagle-owls are Russian desman (Desmana moschata) Pyrenean desman (Galemys pyrenaicus), barbastelle (Barbastella barbastellus), European ground squirrel (Spermophilus citellus), southwestern water vole (Arvicola sapidus), European mink (Mustela lutreola), marbled polecat (Vormela peregusna), lesser white-fronted goose (Anser erythrops), Egyptian vulture (Neophron percnopterus), greater spotted eagle (Clanga clanga), eastern imperial eagle (Aquila heliaca), saker falcon (Falco cherrug), houbara bustard (Chlamydotis undulata), great bustard (Otis tarda), spur-thighed tortoise (Testudo graeca), Atlantic cod (Gadus morhua), European eel (Anguilla anguilla) and lumpfish (Cyclopterus lumpus).

+The great horned owl (Bubo virginianus), also known as the tiger owl (originally derived from early naturalists' description as the "winged tiger" or "tiger of the air"), or the hoot owl, is a large owl native to the Americas. It is an extremely adaptable bird with a vast range and is the most widely distributed true owl in the Americas. Its primary diet is rabbits and hares, rats and mice, and voles, although it freely hunts any animal it can overtake, including rodents and other small mammals, larger mid-sized mammals, birds, reptiles, amphibians, and invertebrates. In ornithological study, the great horned owl is often compared to the Eurasian eagle-owl (Bubo bubo), a closely related species, which despite the latter's notably larger size, occupies the same ecological niche in Eurasia, and the red-tailed hawk (Buteo jamaicensis), with which it often shares similar habitat, prey, and nesting habits by day, thus is something of a diurnal ecological equivalent. The great horned owl is one of the earliest nesting birds in North America, often laying eggs weeks or even months before other raptorial birds.
+
+
+== Description ==
+The great horned owl is generally colored for camouflage. The underparts of the species are usually light with some brown horizontal barring; the upper parts and upper wings are generally a mottled brown usually bearing heavy, complex, darker markings. All subspecies are darkly barred to some extent along the sides, as well. 
+
+A variable-sized white patch  is seen on the throat. The white throat may continue as a streak running down the middle of the breast even when the birds are not displaying, which in particularly pale individuals can widen at the belly into a large white area. South American great horned owls typically have a smaller white throat patch, often unseen unless actively displaying, and rarely display the white area on the chest. Individual and regional variations in overall color occur, with birds from the subarctic showing a washed-out, light-buff color, while those from the Pacific Coast of North America, Central America, and much of South America can be a dark brownish color overlaid with blackish blotching. The skin of the feet and legs, though almost entirely obscured by feathers, is black. Even tropical great horned owls have feathered legs and feet. The feathers on the feet of the great horned owl are the second-longest known in any owl (after the snowy owl). The bill is dark gunmetal-gray, as are the talons.All great horned owls have a facial disc. This can be reddish, brown, or gray in color (depending on geographical and racial variation) and is demarked by a dark rim culminating in bold, blackish side brackets. This species' "horns" are tufts of feathers, called plumicorns. The purpose of plumicorns is not fully understood, but the hypothesis that they serve as a visual cue in territorial and sociosexual interactions with other owls is generally accepted.
+
+
+=== Physiology and measurements ===
+
+The great horned owl is the heaviest extant owl in Central and South America and is the second-heaviest owl in North America, after the closely related, but very different-looking snowy owl. It is heavily built, with a barrel-shaped body, a large head, and broad wings. Its size can vary considerably across its range, with populations in interior Alaska and Ontario being largest and populations in California and Texas being smallest, though those from the Yucatán Peninsula and Baja California appear to be even smaller. Adult great horned owls range in length from 43 to 64 cm (17 to 25 in), with an average of 55 cm (22 in), and possess a wingspan of 91 to 153 cm (3 ft 0 in to 5 ft 0 in), with an average of 122 cm (48 in). Females are somewhat larger than males. Mean body weight is 1,608 g (3.545 lb) for females and 1,224 g (2.698 lb) for males. Depending on subspecies, maximum weight can reach 2,503 g (5.518 lb).
+
+The wing chord length is 297–400 mm (11.7–15.7 in). The wing loading, the measured wing area compared to weight, is high, meaning the wings are relatively small in surface area for the bird's weight; the species' wing loading has been described as proportionately the highest among raptors. The tail, being relatively short as is typical of most owls, is 175 to 252 mm (6.9 to 9.9 in) long. Like other owl species, the great horned owl is capable of “silent flight”, which is the way owls fly while making almost no discernable noise, despite their large size. This is made possible thanks to three main components of the owl's wing structure. The leading edge of their feathers have serrations that help to disrupt the turbulence generated by wing flapping, then the softer feathers help deaden the sound, and finally the trailing fringe of the feathers that works to finish cutting the sounds made by flight. The structure of the great horned owl wing also allows it to fly at a very low speeds for the size of the species, as slow as 2 miles per hour when they are gliding on breezes.
+
+The legs, feet, and talons are large and powerful. Tarsal length is 54–80 mm (2.1–3.1 in). The average foot span of a fully spread foot, from talon to talon, is around 20 cm (7.9 in), as compared to 8 cm (3.1 in) in long-eared owls, 13 to 15 cm (5.1 to 5.9 in) in barn owls, and 18 cm (7.1 in) in the great grey owl. Great horned owls can apply at least 300 lb/in2 of crushing power in their talons, a pressure considerably greater than the human hand is capable of exerting. In some big females, the gripping power of the great horned owl may be comparable to much larger raptor species such as the golden eagle.The hard, inflexible bill of the great horned owl is 3.3–5.2 cm (1.3–2.0 in) long, although the culmen, the exposed bill portion as measured along the top of the beak, is only 2.1 to 3.3 cm (0.83 to 1.30 in).The outer ear openings, which are concealed by feathers on the sides of the head, are relatively smaller than those of the Eurasian eagle owl, being 2.3 cm (0.91 in) in vertical axis, with the left ear slightly larger than the right. Like most exclusively (or near exclusively) nocturnal species, the great horned owl has asymmetrical ear holes that allow for the triangulation of sounds when hunting in the dark. The different-height holes, while still close together, are differentiated enough that the owl is able to use the timing and direction of the sound waves hitting each hole to precisely locate prey even if the prey is located under cover such as snow. The disc-like shape of their faces also helps to direct the sounds they hear toward their ears. While the true nature/purpose of the ear tufts that are present on the great horned owl is unknown, researchers agree that the tufts do not play any role in the hearing ability of the owl. It is estimated that their hearing is up to ten times that of a human being.The great horned owl's eyes, just slightly smaller than the eyes of a human being, are large even for an owl and rank proportionately among the largest eyes of all terrestrial vertebrates. The great horned owl has cylindrical eyes which creates more distance from the lens of the eye to the retina, which allows it to act more like a telephoto lens for farther distance sight compared to that possible from round eyes. They are visually highly adapted for nocturnal hunting and provide a wide, almost completely binocular field of view, a large corneal surface and a predominantly rod retina. The great horned owl's eye contains both rods and cones like most species that see in color, but the vision of a great horned owl closely resembles that of many other nocturnal species. The peak wavelengths that are observed by the cones is 555 nm and the research suggests that the great horned owl has relatively weak color vision, especially compared to other bird species. Despite (or perhaps as a result of) the poorer sense of color vision, the owl manages to have excellent night vision. Instead of turning its eyes, an owl must turn its whole head, and the great horned owl can rotate its neck 270°. The iris is yellow, except in the amber-eyed South American great horned owl (B. v. nacurutu).

+=== Calls ===
+The great horned owl's song is normally a low-pitched but loud ho-ho-hoo hoo hoo (or also transcribed as bu-bubu booh, who-hoo-ho-oo or who-ho-o-o, whoo-hoo-o-o, whoo) and can last for four or five syllables. The call is resonant and has warranted descriptions as varied as "solemn" and "terrifying". The female's call is higher and rises in pitch at the end of the call. Female vocalizations are higher in pitch because of a smaller syrinx in the larger sex. Calling seems to peak after rather than before midnight. Usually, territorial hooting decreases in February or March at the onset of egg laying. On occasion, this species exhibits "an indescribable assemblage of hoots, chuckles, screeches, and squawks, given so rapidly and disconnectedly that the effect is both startling and amusing". Descriptions of some of these odd sounds including a growling krrooo-ooo note pair, a laughing whar, whah, wha-a-a-a-ah, a high-pitched ank, ank, ank; a weak, soft erk, erk, a cat-like meee-owwwwww, a hawk-like note of ke-yah, ke-yah, and a nighthawk-like peent. These vocalizations may be variously uttered when the birds are disturbed and angered at the nest (frequently preceding an attack on an interloping human or other animal), represent the vocal development of young owls, or are given during courtship and during territorial disputes with other owls. Young owls still in the care of their parents make loud, persistent hissing or loud, piercing screeching sounds that are often confused with the calls of the barn owl.
+
+
+=== Species identification ===
+
+The combination of the species' bulk, prominent ear tufts and barred plumage distinguishes it through much of the range, but it may be easily confused with the lesser or Magellanic horned owl (B. magellanicus), which may overlap in range. The Magellanic horned owl was once considered a subspecies of the great horned, but is now almost universally considered a distinct species, as is supported by genetic materials, with the great horned being the paraspecies. Overall coloration is similar, but the Magellanic is markedly smaller with smaller feet and a smaller head, with finer, but more numerous brownish bars on the underside, rather than the blotchy, irregular barring typical of great horned owls. Other eagle-owls may superficially be somewhat similar, but the species is generically allopatric with the exception of wintering snowy owls. More tropical species with ear tufts, the stygian owl (A. stygius) and striped owl (A. clamator), are much smaller. Other large owls lack ear tufts.
+
+
+== Taxonomy ==
+The great horned owl is part of the genus Bubo, which may include as many as 25 other extant taxa, predominantly distributed throughout Africa. The great horned owl represents one of the one or two radiations of this genus across the Bering land bridge to the Americas. Whereas the Magellanic horned owl clearly divided once the owl had spread through the Americas, the consensus seems to be that the snowy owl and the great horned owl divided back in Eurasia and the snowy then spread back over the Arctic through northernmost North America separately from the radiation of the horned owl. The great horned and Eurasian eagle-owls may in fact be conspecifics, based on similarities in life history, geographic distribution, and appearance. In one case, a zoo-kept male great horned owl and female Eurasian eagle-owl produced an apparently healthy hybrid. Genetic testing indicates that the snowy owl, not the Eurasian eagle-owl, is the most closely related living species. Pleistocene era fossils have been found of Bubo owls in North America, which may either be distinct species or paleosubspecies, from as far east as Georgia, but predominantly in the Rocky Mountains and to the west of them. Almost all fossils indicate these owls were larger than modern great horned owls.
+
+
+=== Subspecies ===
+
+A large number of subspecies, more than 20 altogether, have been named. However, many of these are not true subspecies and only examples of individual or clinal variation. Subspecies differences are mainly in color and size and generally follow Gloger's and Bergmann's rules: The most conservative treatments of great horned owl subspecies may describe as few as 10, although an intermediate number is typical in most writings.
+Common/eastern great horned owl (Bubo virginianus virginianus) (Gmelin, 1788)Eastern United States eastwards from at least as far west as Minnesota to Texas; northeastwards in distribution to southern Quebec, southern Ontario, Nova Scotia and Prince Edward Island. Resident all-year. The race B. v. mesembrinus from Central America south of the Isthmus of Tehuantepec, may be merely a southerly leg of this race, as its coloring is almost exactly the same as virginianus, although with rather smaller body size. However, mesembrinus type owls are discontinuous in range, with only paler owls from pallescens and mayensis found in the in-between range before the northern virginianus reappears back up in South Texas.
+The "nominate race" is a medium-hued form, neither darkly saturated nor strikingly pale. Darker gray or somewhat paler individuals are known. It tends to be richly tinged with rufous and barred distinctly blackish-brown below with rather soft contrast. The feet can range from tawny to buff to creamy and are the legs are typically barred dark to a moderate extent. The facial disc is often a solid cinnamon-red color. This is mid-to-large race, with a wing chord length of 319–371 mm (12.6–14.6 in), averaging 339 mm (13.3 in), in males and 343–388 mm (13.5–15.3 in), averaging 362.8 mm (14.28 in), in females. Unexpectedly, although it is not the longest-winged, the nominate is the heaviest known race as males weigh from 985 to 1,588 g (2.172 to 3.501 lb), averaging 1,318 g (2.906 lb), and females weigh from 1,417 to 2,503 g (3.124 to 5.518 lb), averaging 1,768.5 g (3.899 lb); the prior figures originally from a huge sample around Michigan. In comparison, B. v. subarcticus, though averaging longer in wing length averages somewhat less heavy. On the contrary, in Costa Rica, within the range of the possibly synonymous mesembrinus, great horned owls average approximately 1,000 g (2.2 lb), the lightest average mass reported anywhere for this species.  Other standard measurements of this race are a tail length of 190 to 235 mm (7.5 to 9.3 in), a tarsus length of about 56 to 58 mm (2.2 to 2.3 in) and a bill length of 35 to 50 mm (1.4 to 2.0 in). B. v. virginianus also tends to have relatively the longest ear tufts on any race.South American great horned owl (Bubo virginianus nacurutu) (Vieillot, 1817)A lowland form occurring in disjunct populations from eastern Colombia to the Guyanas; also from Brazil and Uruguay south of the Amazon Basin to Bolivia, the Buenos Aires Province in northern Argentina and western Paraguay; resident all-year. Includes the proposed subspecies scotinus, elutus, and deserti. The status of this form, especially the relationships between the scattered subpopulations and with ssp. nigrescens and the Magellanic horned owl, deserves more study.
+Dull, earthy brownish color is typical; birds from the semiarid interior of Brazil often have much white on uppertail- and ear-coverts against a dull gray background (sometimes separated as deserti). This race is less fuscous than nigrescens. It is the only subspecies where the iris is amber, not yellow. The Magellanic horned owl, while somewhat similar in coloring, has yellow eyes like other horned owls, not amber eyes. B. v. nacurutu is a medium-sized race, smaller than most in North America but not as small as some of the Mexican races. The wing chord length is 330–354 mm (13.0–13.9 in) in males and 340–376 mm (13.4–14.8 in) in females. The tail in both sexes can range from 184 to 217 mm (7.2 to 8.5 in). Only three birds have had published weights, two males scaling 1,011 and 1,132 g (2.229 and 2.496 lb) and one female weighing 1,050 g (2.31 lb). The most notable feature of this race is its large bill, at 43 to 52 mm (1.7 to 2.0 in), which is the biggest of any horned owl race despite the otherwise moderate size of B. v. nacurutu.Northern/sub-Arctic great horned owl (Bubo virginianus subarcticus) (Hoy, 1852)Breeding range from Mackenzie, British Columbia region east to the southern Hudson Bay; southern limit unclear but at least reaches to Montana and North Dakota. Non-breeding birds are regularly found south to latitude 45°S, i.e. Wyoming or South Dakota, occasionally ranging beyond this limit especially in years with low prey in the north. This race includes the birds described as occidentalis (based on a wintering individual, as was the original subarcticus) and sclariventris. The older name wapacuthu was occasionally used for this subspecies, but it cannot with certainty be assigned to a recognizable taxon and is thus considered a nomen dubium. The population described as algistus is probably based on wandering individuals and/or various intergrades of subarcticus with other races.
+This is the palest form of horned owl, with the ground color essentially whitish with a faint buff tinge above; black underside barring variable from indistinct to pronounced, being most often prominent on the upper chest amongst otherwise pale plumage. This race shows little to no reddish coloration. B. v. subarcticus shows a very high degree of clinal variation, ranging from in the Contiguous United States where owls are often medium-grayish and more heavily marked to the subarctic zone in Canada where very pale birds with almost non-existent markings are prominent. Very pale birds are similar to a young female snowy owl from a distance. In this race, the feet range from immaculate white to buff, with little or no mottling. In the west of Canada, subarcticus may hybridize with the dark saturatus and may do the same with this similarly dark heterocnemis in the east. In both cases, they may produce intermediate looking hybrids of reddish tone, like a virginianus but with sharper contrasting of colors. This is one of the largest-bodied subspecies. The wing chord length is 323–372 mm (12.7–14.6 in), averaging 346.7 mm (13.65 in), in males and 339–390 mm (13.3–15.4 in), averaging 362.5 mm (14.27 in), in females. Body mass ranges from 865 to 1,460 g (1.907 to 3.219 lb), averaging 1,196.5 g (2.638 lb), in males and from 1,112 to 2,046 g (2.452 to 4.511 lb), averaging 1,556 g (3.430 lb), in females. Tail length is 200 to 225 mm (7.9 to 8.9 in) and 220 to 240 mm (8.7 to 9.4 in) in males and females, respectively. Bill length is 35 to 43 mm (1.4 to 1.7 in) in both and one bird had a tarsus of 66 mm (2.6 in).California great horned owl (Bubo virginianus pacificus) (Cassin, 1854)Central and southern California west of the Sierra Nevada except for the San Joaquin Valley, south to Northwestern Baja California, Mexico. Intergrades with pallescens in San Diego County, California (see also below). Resident all-year.
+Very rich brown, dark underside barring distinct, less pronounced than in saturatus but more pronounced than in pallescens. Humeral area is black. Feet are mottled dark. The facial disc is often even darkly mottled. This is a fairly small-bodied race, in fact including the lightest wild great horned owl adult ever weighed. The wing chord length is 305–362 mm (12.0–14.3 in), averaging 332.5 mm (13.09 in), in males and 335–375 mm (13.2–14.8 in), averaging 351.4 mm (13.83 in), in females. Body mass ranges from 680 to 1,272 g (1.499 to 2.804 lb), averaging 991.7 g (2.186 lb), in males and from 825 to 1,668 g (1.819 to 3.677 lb), averaging 1,312.7 g (2.894 lb), in females. Tail length is 175 to 218 mm (6.9 to 8.6 in) and 203 to 230 mm (8.0 to 9.1 in) in males and females, respectively. Bill length is 34 to 41 mm (1.3 to 1.6 in) and one bird had a tarsus of 57 mm (2.2 in).Coastal great horned owl (Bubo virginianus saturatus) (Ridgway, 1877)Pacific coast from southeastern Alaska to northern California. Includes the previously described form of  B. v. leucomelas. The often-recognized race B. v. lagophonus is often now considered a mere clinal variation of the same race from interior Alaska to Oregon, the Snake River, and northwestern Montana. These forms may be reported in winter as far south as Colorado and Texas, but these are in times of irruption.
+A dark and overall brownish form with heavily barred and mottled underside, with a dull tawny base. Inland birds (lagophonus) tend to have a more grayish base, the coastal owls being more richly brown. Otherwise, inland and coastal owls are practically the same. The facial disc can range from gray to reddish-gray to dark rufous. The feet are fairly dusky gray typically, although some buff-footed individuals are known, and legs are more prominently barred with black than in other North American races. This is a large race going on linear measurements, which in Alaskan owls outmatch those of all other races but for heterocnemis in Ontario (which may itself be a discontinuous eastern wing of this race). The wing chord length is 330–370 mm (13–15 in), averaging 348.3 mm (13.71 in), in males and 339–400 mm (13.3–15.7 in), averaging 374.7 mm (14.75 in), in females. Tail length is 191 to 245 mm (7.5 to 9.6 in) and 196 to 252 mm (7.7 to 9.9 in) in males and females. In both sexes, known bill and tarsal lengths are 35 to 44 mm (1.4 to 1.7 in) and 62 to 70 mm (2.4 to 2.8 in). No weights are known to have been published.North Andean great horned owl (Bubo virginianus nigrescens) (Berlepsch, 1884)Andes; arid temperate and puna zones from Colombia to northwestern Peru. Resident all-year round. Presumably synonymous with the described columbianus.
+A dark, cold gray-brown form with heavy fuscous blotching. Arguably this is the darkest colored race on average, though it could be rivaled by individuals from saturatus and elachistus. This race has only minimally the rufous tinge seen in other darkish races, although some nigrescens may have a cinnamon facial disc. The largest winged race of owl in South America, this owl has a wing chord length of 345–365 mm (13.6–14.4 in) in males and 350–382 mm (13.8–15.0 in) in females. The tail in both sexes can range from 185 to 217 mm (7.3 to 8.5 in). Bill length is 40 to 50 mm (1.6 to 2.0 in), again relatively long as in nacurutu and one bird had a tarsal length of 80 mm (3.1 in), indicating relatively long legs in the race. No published weights are known. Apparently, despite its sizeable wing area, nigrescens is notably smaller overall when specimens are compared side-by-side with those from saturatus.Desert great horned owl (Bubo virginianus pallescens) (Stone, 1897)San Joaquin Valley southeastwards through arid regions of southeastern California and southern Utah eastwards to western Kansas and southwards to Guerrero and western Veracruz in Mexico; intergrades with pacificus in San Diego County, if not elsewhere; vagrant individuals of saturatus and the Rocky Mountains population, which look similar to intergrades, also seem to occur in its range. Resident all-year. This race is likely synonymous with melanocercus.
+A pale dusky buff form with indistinct barring, especially on the underside. Darker individuals tend to have a deeper fulvous base to their upper sides. Humeral area is umber in color and the feathers of the feet are white and usually unmarked. A small race, it averages slightly larger in wing length than pacificus but weighs less on average. The wing chord length is 318–367 mm (12.5–14.4 in), averaging 337.2 mm (13.28 in), in males and 332–381 mm (13.1–15.0 in), averaging 348.9 mm (13.74 in), in females. Body mass ranges from 724 to 1,257 g (1.596 to 2.771 lb), averaging 914.2 g (2.015 lb), in males and from 801 to 1,550 g (1.766 to 3.417 lb), averaging 1,142.2 g (2.518 lb), in females. In both sexes, tail length is 190 to 235 mm (7.5 to 9.3 in) and bill length is 33 to 43 mm (1.3 to 1.7 in).Yucatán great horned owl (Bubo virginianus mayensis) (Nelson, 1901)Endemic to the southern two-thirds of the Yucatán Peninsula. Resident all-year.
+A medium-pale form, fairly similar to pallescens in both hue and ventral markings. Going on linear measurements, B. v. mayensis is smaller than all North American horned owls, even the smallish pallescens, and is only slightly larger at median than the following race. This race has wing chord and tail lengths of 297–340 mm (11.7–13.4 in) and 180 to 198 mm (7.1 to 7.8 in) in males and 303–357 mm (11.9–14.1 in) and 199 to 210 mm (7.8 to 8.3 in) in females. In both sexes, the bill length is 39 to 41 mm (1.5 to 1.6 in) and tarsal length is 54 to 65 mm (2.1 to 2.6 in).Baja California great horned owl (Bubo virginianus elachistus) (Brewster, 1902)Southern Baja California, Mexico. Resident all-year.
+Similar in color to pacificus but even darker and more heavily barred, like a miniaturized saturatus. It is considerably (5–10%) smaller than pacificus linearly; some size overlap does occur though. On average, it is the smallest known subspecies. Males have a wing chord length of 305 to 335 mm (12.0 to 13.2 in), tail length of 175 to 206 mm (6.9 to 8.1 in) and bill length of 33 to 38 mm (1.3 to 1.5 in). A single female had a wing chord of 330 mm (13 in) and tail of 211 mm (8.3 in).Northeastern great horned owl (Bubo virginianus heterocnemis) (Oberholser, 1904)Breeds in eastern Canada (northern Quebec, Labrador, Newfoundland). Its southern breeding range seems to be delineated by the Saint Lawrence River.  In winter, this race may disperses southwards throughout Ontario to as far as the Northeastern United States. This subspecies may be synonymous with saturatus, although it is distributed far to the east of that race. B. v. heterocnemis is surrounded by the much paler subarcticus to its west and quite differently marked virginianus to its south, the latter two overlap and possibly hybridize in some of the northeast.
+A fairly dark and grey, heavily barred form. Feet pale with dusky mottling. Going on median reported linear measurements (since body mass is unknown), this is the largest bodied subspecies on average. Males have a wing chord length of 350 to 365 mm (13.8 to 14.4 in) and females range from 370 to 390 mm (15 to 15 in). In both sexes, the tail is 220 to 250 mm (8.7 to 9.8 in) and the bill is 38 to 48 mm (1.5 to 1.9 in).Rocky Mountains great horned owl (Bubo virginianus pinorum) (Dickerman & Johnson, 2008)The Rocky Mountains population breeds south of the Snake River in Idaho south to Arizona, New Mexico, and the Guadalupe Mountains of Texas. Westwards, it is presumed to occur to the Modoc Plateau and Mono Lake of California. This race was included in the presumed subspecies occidentalis, but was recently first described and named as a distinct subspecies and makes up the missing piece in the once-muddled distribution of great horned owls in the West and Rockies. Downslope movements into valleys occupied by pallescens might occur, but this needs study.
+A medium gray form, intermediate in coloring between saturatus and pallescens. Moderately barred and tinged buff or ochraceous on the underside. Feet mottled. This is a largish race, wing chord lengths being inexplicably greater in males, at 350 to 397 mm (13.8 to 15.6 in), than in females, at 327 to 367 mm (12.9 to 14.4 in). Tail length can range from 190 to 233 mm (7.5 to 9.2 in) and a female weighed 1,246 g (2.747 lb).
+
+
+== Distribution and habitat ==
+
+The breeding habitat of the great horned owl extends high into the subarctic of North America, where they are found up to the northwestern and southern Mackenzie Mountains, Keewatin, Ontario, northern Manitoba, Fort Chimo in Ungava, Okak, Newfoundland and Labrador, Anticosti Island and Prince Edward Island. They are distributed throughout most of North America and very spottily in Central America and then down into South America south to upland regions of Argentina, Bolivia and Peru, before they give way to the Magellanic horned owl, which thence ranges all the way to Tierra del Fuego, the southern tip of the continent. It is absent or rare from southern Guatemala, El Salvador, Nicaragua, and Costa Rica to Panama (where only two records) in Central America and the mangrove forests of northwestern South America. The species is also absent from the West Indies, the Haida Gwaii and almost all off-shore islands in the Americas, its ability to colonize islands apparently being considerably less than those of barn owls and short-eared owls. Since the division into two species, the great horned owl is the second most widely distributed owl in the Americas, just after the barn owl.The great horned owl is among the world's most adaptable owls or even bird species in terms of habitat. The great horned owl can take up residence in trees that border all manner of deciduous, coniferous, and mixed forests, tropical rainforests, pampas, prairie, mountainous areas, deserts, subarctic tundra, rocky coasts, mangrove swamp forests, and some urban areas. It is less common in the more extreme areas of the Americas. In the Mojave and Sonora Deserts, they are absent from the heart of the deserts and are only found on the vegetated or rocky fringes. Even in North America, they are rare in landscapes including more than 70% old-growth forest, such as the aspen forest of the Rockies. They have only been recorded a handful of times in true rainforests such as the Amazon rainforest. In the Appalachian Mountains, they appear to use old-growth forest but in Arkansas are actually often found near temporary agricultural openings in the midst of large areas of woodland. Similarly in south-central Pennsylvania, the owls use cropland and pasture more than deciduous and total forest cover, indicating preference for fragmented landscapes. In prairies, grasslands and deserts, they can successfully live year round as long as there are rocky canyons, steep gullies and/or wooded coulees with shade-giving trees to provide them shelter and nesting sites.In mountainous areas of North America, they are usually absent above the tree line, but great horned owls can be found up to 2,100 m (6,900 ft) in California and 3,300 m (10,800 ft) in the Rockies. In the Andean Mountains,  on the other hand, they have adapted to being a true montane species, often found at least 3,300 m (10,800 ft) above sea level and are regularly recorded in treeless Puna grassland zones at 4,100 to 4,500 m (13,500 to 14,800 ft) in Ecuador and Peru. They are generally rare in non-tidal wetland habitat, and are replaced in the high Arctic tundra by snowy owls. They prefer areas where open habitats, which they often hunt in, and woods, where they tend to roost and nest, are juxtaposed. Thus lightly populated rural regions can be ideal. This species can occasionally be found in urban or suburban areas. However, they seem to prefer areas with less human activity and are most likely to be found in park-like settings in such developed areas, unlike eastern and western screech owls (Megascops asio & M. kennicottii) which may regularly occur in busy suburban settings. All mated great horned owls are permanent residents of their territories, but unmated and younger birds move freely in search of company and a territory, and leave regions with little food in winter.
+
+
+== Behavior ==
+
+In most aspects of their behavior, great horned owls are typical of owls and most birds of prey. From experimentally raising young owls in captivity, Paul L. Errington felt that they were a bird of "essentially low intelligence" that could only hunt when partially wild and instinctually driven by hunger to hunt whatever they first encounter. He showed captive birds that were provided strips of meat from hatching, rather than having to hunt or to simulate hunting to obtain food, had no capacity to hunt. On the contrary, William J. Baerg compared behaviorally his captive-raised great horned owls to parrots, which are famously intelligent birds, although not as often playful "it knows its keeper and usually accepts whatever he wishes to do with a good deal of tolerance". Arthur C. Bent also noted the variability in temperaments of great horned owls to their handlers, some generally pleasant, though most are eventually aggressive. Most captive specimens, once mature, seem to resent attempts at contact and are often given to attacking their keepers. They will only follow cues when conditioned from an early age but rarely with the same level of success seen in some diurnal birds of prey trained for falconry or entertainment, although this does not necessarily correlate with intelligence as posited by Errington. Carl D. Marti also disagrees with Errington's assessments, noting that their prey selection is not as "completely random as Errington suggested"; while "Great Horned Owls appeared to select their mammalian prey in general relation to the prey populations...cottontails, appeared to be selected as prey out of relation to their population status."Like most owls, the great horned owl makes great use of secrecy and stealth. Due to its natural-colored plumage, it is well camouflaged both while active at night and while roosting during the day. During the daytime it roosts usually in large trees (including snags & large hollows but usually thick branches) but may occasionally be in crevices or small caves in rocks or in dense shrubbery. Pine and other coniferous trees may be preferred where available since they are particularly dense and provide cover throughout the year. Typically, males have a favorite roosting site not far from the nest, sometimes used over successive years. While roosting, great horned owls may rest in the "tall-thin" position, where they sit as erect and hold themselves as slim as is possible. The kind of posture is well known as a further method of camouflage for other owls, like long-eared owls or great grey owls, especially if humans or other potential mammalian carnivores approach them. The Eurasian eagle owl rarely, if ever, assumes the tall-thin position. Outside of the nesting season, great horned owls may roost wherever their foraging path ends at dawn. Generally great horned owls are active at night, although in some areas they may be active in the late afternoon or early morning. At dusk, the owl utters a few calls before flying to a more open sing-post, i.e. large bare branch or large rocks to deliver song. Normally several perches are used to mark occupied territory or to attract a female. Despite its camouflage and cryptic locations, this species can still sometimes be spotted on its daytime roosts, especially by American crows (Corvus brachyrhynchos). Since owls are, next to red-tailed hawks, perhaps the main predator of crows and their young, crows sometimes congregate from considerable distances to mob owls and caw angrily at them for hours on end. When the owls try to fly off to avoid this harassment, they are often followed by the corvids.
+
+
+=== Territoriality and movements ===
+Typically, great horned owls are highly sedentary, often capable of utilizing a single territory throughout their mature lives. Although some species such as snowy owls, northern saw-whet owls, long-eared and short-eared owls are true migrants, most North American owls are not migratory and will generally show fidelity to a single territory year around. In great horned owls, mated pairs occupy territories year-round and long-term. Territories are established and maintained through hooting, with highest activity before egg-laying and second peak in autumn when juveniles disperse, and can range from an average of 16 km2 (6.2 sq mi) in Yukon to an average of 2.1 km2 (0.81 sq mi) in Wyoming.Most territorial defense is performed by males, but females frequently assist their partners in hooting contests with neighbors or intruders, even during incubation. On occasion, although territory borders may be successfully maintained via vocalizations alone without even seeing the competing owl, such confrontations may turn physical, with various levels of threats distinguished. The highest threat level involves the spreading of wings, bill-clapping, hissing, higher-pitched screams of longer duration, with general body poised to strike with its feet at intruder. If the intruder continues to press the confrontation, the defending owl will "hop" forward and strike it with feet, attempting to grasp and rake with claws.Territoriality appears to place a limit on the number of breeding pairs in a given area. Individuals prevented from establishing a territory live a silent existence as "floaters". Radio-telemetry revealed that such floaters concentrate along boundaries of established territories. At Kluane Lake in Yukon, incursions into neighboring territories were observed only twice—by females when a neighboring female had died or emigrated, suggesting that territorial defense may be sex-specific. At least four dead great horned owls in Kluane were apparently killed by others of their own species in territorial conflicts. Owls killed by other horned owls are sometimes cannibalized, although the origin of the killing may have been territorial aggression. Northern populations occasionally irrupt south during times of food shortage, but there is no annual migration even at the northern limits of the great horned owl's range.

+
+=== Hunting behavior ===
+
+Hunting tends to peak between 8:30 pm and midnight and then can resume from 4:30 am to sunrise. Hunting tends to be most prolonged during winter by virtue of prey being more scarce.  However, great horned owls can learn to target certain prey during daylight in the afternoon when it is more vulnerable, such as eastern fox squirrels (Sciurus niger) while they're building their leaf nests and chuckawallas (Sauromalus ater) sunning themselves on desert rocks. Owls hunt mainly by watching from a snag, pole or other high perch. During hunting forays, they often fly about 50 to 100 m (160 to 330 ft) from perch to perch, stopping to survey for food at each, until they sense a prey item below. From such vantage points, owls dive down to the ground, often with wings folded, to ambush their prey. Effective maximum hunting distance of an owl from an elevated perch is 90 m (300 ft). Due to their short but broad wings, great horned owls are ideally suited for low speed and maneuverability. Despite reports that they do not hunt on the wing, they also sometimes hunt by flying low over openings on the ground, scanning below for prey activity. Great horned owls can fly at speeds of more than 65 km/h (40 mph) in level flight. Hunting flights are slow, often quartering low above the ground where prey is likely to occur in open country or open woodland. Brief hovering flight (for about 6–18 seconds) has been described, especially in windy areas. On occasion owls may actually walk on the ground in pursuit of small prey or, rarely, inside a chicken coop to prey on the fowl within. Rodents and invertebrates may be caught on foot around the base of bushes, through grassy areas, and near culverts and other human structures in range and farm habitat. The great horned owl is generally a poor walker on the ground; it walks like a starling, with a pronounced side-to-side gait. They have been known to wade into shallow water for aquatic prey, although this has been only rarely reported. Owls can snatch birds and some arboreal mammals directly from tree branches in a glide as well. The stiff feathering of their wings allows owls to produce minimal sound in flight while hunting.Almost all prey are killed by crushing with the owl's feet or by incidentally stabbing of the talons, though some may be bitten about the face as well. Prey is swallowed whole when possible. When prey is swallowed whole, owls regurgitate pellets of bone and other non-digestible bits about 6 to 10 hours later, usually in the same location where the prey was consumed. Great horned owl pellets are dark gray or brown in color and very large, 7.6 to 10.2 cm (3.0 to 4.0 in) long and 3.8 cm (1.5 in) thick, and have been known to contain skulls up to 3 cm (1.2 in) in width inside them. However, not all prey can be swallowed at once, and owls will also fly with prey to a perch and tear off pieces with their bill. Most dietary studies focus on pellets found under perches and around nests, since they provide a more complete picture of the diversity of prey consumed, but prey remains outside of pellets may provide clues to prey excluded from the pellets and a combination of both is recommended. Many large prey items are dismembered. Great horned owls may behead large prey before taking it to its nest or eating perch. The legs may also be removed, as may (in some bird prey) the wings. The great horned owl will also crush the bones of its prey to make it more compact for carrying. On occasion, the owls may return to the kill site to continue eating if the prey is too heavy to fly with after dismemberment. Many owls will accrue a cache of prey, especially those who are nesting. Caches must be at a safe location, usually the crotch of a tall tree. In northern regions, where large prey is prevalent, an owl may let uneaten food freeze and then thaw it out later using its own body heat.  Hunting success seems to require fairly open understory, and experimental testing of microhabitat proved that open areas provided more hunting success on five species of rodent, with cloudy nights and denser bush foliage both decreasing success.
+
+
+== Prey and trophic ecology ==
+ 
+Prey can vary greatly based on opportunity. According to one author, "Almost any living creature that walks, crawls, flies, or swims, except the large mammals, is the great horned owl's legitimate prey". In fact, the great horned owl has the most diverse prey profile of any raptor in the Americas. Over 500 species have been identified as great horned owl prey, with dozens more identified only to genus or general type (especially numerous invertebrates) and presumably several more unknown from their relatively little-studied populations in the Neotropics. Mammals (more than 200 species) and birds (nearly 300 species) make up the majority of their diet. Their diet in North America is made up of 87.6% mammals, 6.1% birds, 1.6% reptiles and amphibians with the remaining 4.7% being made up by insects, other assorted invertebrates and fish. Estimated mass of individual prey for the owls has ranged from as little as 0.4 g (0.014 oz) to as much as 6.8 kg (15 lb) Most prey is in the range of 4 g (0.14 oz) (shrews) to 2,300 g (5.1 lb) (jackrabbits). A single owl requires about 50 to 100 g (1.8 to 3.5 oz) of food per day and can subsist on a large kill over several days. Despite the great diversity of prey taken by these predators, in most of the continental United States from the East to the Midwest as well as Canada and Alaska, great horned owls largely live off just a handful of prey species: three species of lagomorph: the eastern cottontail (Sylvilagus floridanus), the snowshoe hare (Lepus americanus) and the black-tailed jackrabbit (Lepus californicus); two species of New World mice: the white-footed mouse and the North American deermouse (Peromyscus leucopus & maniculatus); approximately three species of vole: the meadow, prairie and woodland voles (Microtus pennsylvanicus, ochrogaster & pinetorum); and one introduced pest, the brown rat.
+
+
+=== Rodents ===
+
+Small rodents form the great majority of great horned owl prey by number. Weighing a mere 14 to 31.5 g (0.49 to 1.11 oz) and 20 to 58 g (0.71 to 2.05 oz) on average, the nine species of New World mice in Peromyscus and eight species voles in Microtus recorded in the diet would appear to be overly small to be as important as they are to a predatory bird of this size. The prominence of these genera is undoubtedly due to the abundance of both genera in the wooded edge habitats frequented by great horned owls. It is estimated that a family of owls with two offspring would need to take about a half dozen (voles) to a dozen (mice) of these rodents every night to satisfy their dietary requirements but apparently the accessibility and abundance of these foods is irresistible as their numeric dominance is indisputable. By winter in areas that hold heavy snow, Peromyscus mice often come to outnumber the voles in the diet since the mice tend to travel over the surface of the snow while the voles make tunnels underneath the snow. In fact, a healthy family of great horned owls can decimate a colony of field rats, thus potentially performing a key role in controlling a highly destructive pest.  Great horned owls living in the timbered fringes of garbage or refuse dumps may subsist mostly on rats.In the Rockies, California, the Southwestern United States and northern Mexico, the diversity of this species' diet rises, in sync with the diversity of rodents. Especially important, from Colorado to Washington state is the northern pocket gopher (Thomomys talpoides), although assorted other pocket gophers (Geomys, Cratogeomys, Zygogeomys, Pappogeomys and other Thomomys ssp.) are readily taken. While the northern weighs from 90 to 120 g (3.2 to 4.2 oz), other pocket gophers hunted average from 95 to 545 g (0.209 to 1.202 lb) in mass. From Washington to Baja California a very important food is the pocket mice, primarily the Great Basin pocket mouse (Perognathus parvus). While the Great Basin species is a relative giant at 22 g (0.78 oz), other hunted pocket mice (which may include both Perognathus and Chaetodipus ssp.) can average nearly as light as 8 g (0.28 oz). In East Texas, the 159 g (5.6 oz) hispid cotton rat (Sigmodon hispidus) is the most commonly recorded prey species. The same species constituted 75% by number of a small sampling in Oklahoma. In semi-desert and other arid habitats, kangaroo rats become increasingly important prey, ten species have been reported in the diet but most prominently the Ord's  and Merriam's kangaroo rats (Dipodomys ordii & merriami), both being widespread, numerous and relatively diminutive (at 42 and 48 g (1.5 and 1.7 oz)). Eight known larger species of kangaroo rats, including the giant kangaroo rat (Dipodomys ingens) averaging at 152 g (5.4 oz), are also taken.The squirrels, including ground squirrels, marmots (Marmota), prairie dogs (Cynomys), chipmunks and tree squirrels, are diurnal and so are largely unavailable to great horned owls as prey. Occasionally though, one will be caught from their leaf nest, nest hole or burrow entrance first thing in the morning or in the late afternoon and approximately 35 species have been successfully predated by these owls. In general larger sized than other rodent families, the species hunting range from the 62 g (2.2 oz) gray-collared chipmunk (Tamias cinereicollis) to the 5,775 g (12.732 lb) hoary marmot (Marmota caligata); thus, squirrels can be provide a very fulfilling meal.  An even larger rodent is sometimes attacked as prey by great horned owls, the North American porcupine (Erethizon dorsatum), in which average adults range from 4,500 to 9,000 g (9.9 to 19.8 lb). This has been determined from owls who have porcupine quills imbedded in them, sometimes resulting in death. On occasion, they are successful in killing porcupine, even adults as determined by the size of the quills left behind and prey remains at bloodied kill sites. Other rodents recorded as secondary prey in North America include flying squirrels (Glaucomys ssp.), the golden mouse (Ochrotomys nuttalli), red-backed voles & bog lemmings (Myodes & Synaptomys ssp.), the muskrat (Ondatra zibethicus), the northern grasshopper mouse (Onychomys leucogaster), the northern pygmy mouse (Baiomys taylori) and jumping mice (Zapus & Napaeozapus ssp.).
+
+
+=== Lagomorphs ===
+ 
+Although generally no match for rodents in sheer quantity of individuals, in terms of prey biomass, the most significant prey of North American great horned owls are hares and rabbits. About a dozen lagomorphs species are known to be hunted by the owl, from the relatively tiny 420 g (0.93 lb) pygmy rabbit to several hares weighing more than 2,000 g (4.4 lb). Two hare species, the black-tailed jackrabbit and snowshoe hare, are so important to the owls as a food source that the local owl populations sharply rise and fall in sync with the hares' cyclical population trends. With adult weights of 800 to 1,900 g (1.8 to 4.2 lb) in adult cottontails, 900 to 2,000 g (2.0 to 4.4 lb) in snowshoe hares and 1,400 to 2,700 g (3.1 to 6.0 lb) in black-tailed jackrabbits, these species are overall the largest regular prey for this species. In Utah, where great horned owls are dependent on the jackrabbits, average brood size rose from 2 at jackrabbit population lows to 3.3 when the jackrabbits were at their peak. At the peak of population cycle, jackrabbits accounted for 90.2% and desert cottontails (Sylvilagus audubonii) for another 8.7% of prey biomass. In the short-grass prairie of Colorado, mountain cottontail (Sylvilagus nuttallii) and black-tailed jackrabbits predominated in October to December, making up 42.9% by number (and nearly all the biomass), thence dropping to 9.3% by number in April, while voles rose to 32.2% peak in May, down to a minimum of 10.2% by number in June. Further north in Colorado, in the absence of jackrabbits, the mountain cottontails falls to third place by number (12.9%) behind the northern pocket gopher (36.5%) and prairie vole (24.7%) but still dominates the biomass, making up about half. In central Utah, the lagomorphs (black-tailed jackrabbit/desert cottontail) and Ord's kangaroo rat each made up 39% of the food by number, respectively. The mountain cottontail dominates the biomass of prey in the Sierran foothills of California, making up 61.1% of the biomass, although are numerically secondary to desert woodrat. Remarkably, in the Morley Nelson Snake River Birds of Prey National Conservation Area of Idaho, individual rodents (1159 counted) were more than 10 times more numerous than lagomorphs (114 counted) by quantity and yet the jackrabbit and mountain cottontail still made up approximately half of the biomass. The dependence on lagomorphs also extends into Mexico, as in Baja California about a quarter of identified prey was black-tailed jackrabbit and either desert or the larger Mexican cottontail (Sylvilagus cunicularius). In the northern boreal forest, great horned owls are even more dependent on the snowshoe hare. At the peak of the 10 year hare cycle, snowshoe hares were by far the largest component of both summer and winter diets (77–81% and 90–99%, respectively, in Alberta; 83–86% and 75–98%, respectively, in Yukon). At the lowest point of the hare's cycle, summer diets consisted of only 0–16% snowshoe hare in Alberta and 12.7% in Yukon. When hares were scarce, great horned owls in these regions fed mostly on large rodents, mice and voles, grouse and ducks. Because fewer of these alternative prey species are available in boreal forest during winter, owls had to emigrate or suffer high mortalities if they stayed. In Alberta, the local population of great horned owls can increase threefold from hare population lows to peaks. The dependency on the snowshoe hare by the great horned owl extends into Alaska as well.
+
+
+=== Other mammals ===
+Other mammals are taken readily as well. From both the tropics and the United States, several species of opossum may be taken, down to the size of the tiny dwarf fat-tailed mouse opossum (Thylamys velutinus). In Brazil, white-eared opossum (Didelphis albiventris) were found in 12% of pellets, but all specimens appeared to be juveniles each weighing about 1,000 g (2.2 lb). Quite differently, in Pennsylvania, Virginia opossum (Didelphis virginianus) made up 6% by number of prey but due to their large size (approximately 2,500 g (5.5 lb)) and that all specimens were adults, they occupied the highest percentage of biomass of any species in a wide study from that state. At least eight species of shrews are taken by opportunity and make up the smallest mammalian prey taken by great horned owls, as specimens of least shrew (Cryptotis parva) or masked shrew (Sorex cinereus) have had an estimated weight of only 2 g (0.071 oz). One of the more regularly taken shrews, though, is the larger 19.5 g (0.69 oz) northern short-tailed shrew (Blarina brevicauda), which was represented in more than 2% of pellets in the Upper Midwest. Moles, of at least four or five species, are also widely but lightly reported as prey. Remnants of armadillo, presumably nine-banded armadillo (Dasypus novemcinctus), have been found around owl nests in the south. 11 species of bat are known to be hunted by great horned owls. One pellet in Texas was found to be composed entirely of Mexican free-tailed bats (Tadarida brasiliensis). Smaller species of mammalian carnivore, such as ringtail (Bassariscus astutus), American mink (Neogale vison), black-footed ferret (Mustela nigripes) and various other small mustelids (Mustela ssp.), are sometimes taken as prey. Prey in the form of canids, like foxes or coyotes (Canis latrans) are often juveniles presumably snatched from the mouths of dens by night. Kit and swift foxes of up to adult size may taken. Surprisingly, at least two cases of a great horned owl preying on an adult raccoon (Procyon lotor) have been reported. One instance of an owl taking a bobcat (Lynx rufus) as prey was also reportedly observed. In one case, a great horned owl was the likely killer of an adult female fisher (Martes pennanti), though young ones are typically taken. Occasionally, domestic carnivores are also prey. A few cases of young or small dogs (Canis lupus familiaris) and several of juvenile and adult cats (Felis silvestris catus) being killed by great horned owls have been reported. The most infamous predatory association amongst relatively larger carnivores is that with skunks. Due to their poor sense of smell, great horned owls are the only predators to routinely attack these bold mammals with impunity. All six skunk species found in North America are reported as prey, including adult striped skunks (Mephitis mephitis), which can be three times as heavy as the attacking owl. In one single nest, the remains of 57 striped skunks were found. Due to the proclivity of skunk predation, great horned owls nests frequently smell strongly of skunk and occasionally stink so powerfully of skunk that they leave the smell at kill sites or on prey remains.
+
+
+=== Birds ===
+
+After mammals, birds rank as the next most important general prey group. Birds are usually considerably secondary in the diet but outnumber the mammals in the diet by diversity, as more than 250 species have been killed in North America alone. Statistically, the most significant avian prey seems to be galliforms, of which they are known to have preyed on 23 species, basically consisting of all of the native species found in the United States. In the Upper Midwest, the ring-necked pheasant (Phasianus colchicus) and northern bobwhite (Colinus virginianus) were the fifth and sixth (out of 124 identified species) most significant prey species in 4838 pellets. Errington characterized the predatory pressure exerted on bobwhites by great horned owls as "light but continuous pressure", which may be considered characteristic of the species' hunting of all galliforms. Usually coveys of quail are partially protected by spending the night roosting communally in dense thickets but should a hunting owl be able to track down the communal roost, losses can be fairly heavy until the roost relocates. Similarly, owls may track down sleeping grouse, which also roost in vegetation but more openly than quail. Some grouse, such as greater prairie chicken (Tympanuchus cupido), sharp-tailed grouse (Tympanuchus phasianellus) and greater sage-grouse (Centrocercus urophasianus),  may also been vulnerable to great horned owls while displaying conspicuously in openings on a lek first thing in the morning. In the boreal forest, especially in years where the snowshoe hare experiences population decreases, great horned owls prey fairly heavily (approximately 25% of biomass) on ruffed grouse (Bonasa umbellus) and spruce grouse (Falcipennis canadensis), enough so in the earlier bird to possibly contribute to population reductions. Larger species of galliform are not immune to predation either. On Protection Island in Washington state, introduced common peafowl (Pavo cristatus) are an important prey item. The wild turkey (Meleagris gallopavo), 4 to 8 kg (8.8 to 17.6 lb) on average between the sexes, is probably the largest bird the great horned owl hunts in which they kill adults. Both full-grown wild turkeys and adult domestic turkeys have been hunted and killed. Under normal circumstances, domestic chicken (Gallus gallus domesticus) will be ignored in favor of wild prey. On occasion, individual owls, especially inexperienced juveniles, will become habitual fowl killers. These errant owls mainly hunt chickens, though will also take domestic guineafowl, turkeys and anything else available. In general, chickens kept in locked cages with enclosed tops overnight are safe from great horned owls; not so chickens left free range or in open enclosures.While galliforms are widely reported, the few cases where great horned owls locally turn to birds as the primary food source over mammals, these may often be local responses to the abundance of breeding water birds or concentrations of roosting water birds, since they tend to roost in relatively open spots. They have been known to predate more than 110 different species of assorted water bird. In prairie wetlands of North Dakota, avian prey, primarily represented by ducks and the American coot (Fulica americana) came to represent 65% by number and 83% by biomass of the diet of the local owls, also including secondarily grebes, smaller rails and shorebirds as well as upland-based species like grey partridge (Perdix perdix), sharp-tailed grouse and passerines. 77% of the ducks in that study were juveniles, the largest duck being a male mallard (Anas platyrhnychos) weighing approximately 1,250 g (2.76 lb), but nearly all the coots were adults. On Protection Island, Washington, where they are no native land mammals, rhinoceros auklets (Cerorhinca monocerata), both adults and nestlings, were the most numerous prey, present in 93% of 120 pellets. Species as large as adult Canada geese, snow goose and great blue herons have been successfully killed. The nestlings of even larger species like trumpeter swans (Cygnus buccinator), American white pelicans (Pelecanus eryhtrorhynchos), brown pelicans (Pelecanus occidentalis) and sandhill cranes (Grus canadensis) have also been killed by these owls.
+Other assorted birds are taken seemingly at random opportunity. The predatory effect of this species on other raptorial birds, which is often considerable, is explored in the following section. In Brazil, it was found in a small study that birds overall outnumbered mammals in pellets, although most were not determined to species and the ones that were shown a tremendously diverse assemblage of birds with no obvious dietary preference. Although not usually numerically significant, 86 species of passerine have been taken by great horned owls. Members from most North American families are known as prey, although among smaller types such as chickadees, warblers, sparrows, cardinals, wrens and most tyrant flycatchers only a few species from each have been recorded. Nonetheless, an occasionally unlucky migrant or local breeder is sometimes snatched. Fledgling songbirds are regularly taken in spring and summer. The smallest avian prey known for great horned owls are the 5.8 g (0.20 oz) blue-grey gnatcatcher (Polioptila caerulea) and the 6.2 g (0.22 oz) ruby-crowned kinglet (Regulus calendula). Somewhat larger bodied families are more prominent, i.e. the corvids (14 species) and icterids (14 species) and, secondarily, the kingbirds (Tyrannus ssp.), thrushes, mimids and European starling (Sturnus vulgaris). This is likely due to the fact that the larger passerines usually roost in relatively open spots and have larger, more conspicuous nests. Crows and ravens tend to be grabbed off of their communal roosts by night.
+
+
+=== Other prey ===
+The great horned owl rarely misses an opportunity to hunt reptiles and amphibians. However, lizards are largely unavailable as prey due to their typically diurnal periods of activity. However, some snakes are partially or largely nocturnal, and more than a dozen species are hunted in North America. Snakes hunted range from small, innocuous garter snakes (Thamnophis ssp.) and night snakes (Hypsiglena torquata) to venomous species like cottonmouths (Agkistrodon piscivorus) and prairie rattlesnakes (Crotalus virdis) and formidable, large species like common king snakes (Lampropeltis getula) and black rat snakes (Pantherophis obsoletus), which in mature specimens can rival the owl in mass and sheer predatory power. The capture of the hatchlings of very large reptiles such as loggerhead turtles (Caretta caretta) and American alligators (Alligator mississippiensis) by great horned owls has been reported, in both cases likely when the baby reptiles are attempting to make their way to the security of water. On rare occasion, salamanders, frogs and toads are reported as prey.  On rare occasions, fish are taken including goldfish (Carassius auratus), bluegill (Lepomis macrochirus), bullheads (Ameiurus ssp.), other catfish, suckers, sunfish, eels and dace and chub. Many types of invertebrates are recorded as prey. These include mainly insects, but also crayfish, crabs, spiders, scorpions and worms. The occasionally invertebrate prey taken largely consists of common, large insects such as various beetles, crickets, grasshoppers, water bugs and katydids, some of which the great horned owl has even reportedly caught via "hawking", i.e. swooping at on the wing. In some cases, the content of insects in great horned owl pellets may actually be due to the owls eating other birds which have freshly eaten insects in their own stomachs. It is commonly believed that routine insectivory in great horned owls is mainly restricted to inexperienced young owls too unskilled to graduate to larger prey yet. It is clearly inefficient for owls of this size to attempt to raise young on a diet of foods as small as insects. Although rare, carrion-feeding has been recorded in great horned owls, especially ones wintering in Canada and other northern areas during harsh weather. Road kills are sometimes opportunistically eaten. A case of an owl scavenging a white-tailed deer (Odocoileus virginianus) carcass, ultimately tearing off the deer's leg, was captured on a motion capture video camera set out to film wildlife.
+
+
+=== Urban vs rural diet ===
+Studies comparing the diets of rural and urban great horned owls have identified that the most abundant rodent prey in their environment fulfils the majority of their diet. A study of food niche overlap between closely nested barn and great horned owls living in rural north-eastern Oregon identified voles as by far the most common prey. In southwestern British Columbia, Townsend's voles were the most common prey species, while consumption of rats increased as the nesting location became more urban and rats replaced voles as the most abundant and stable food source.  A similar focus on rats was found in populations in urban parks in Seattle.  Although a stable and highly abundant food source, a diet consisting of primarily rats can be harmful to urban great horned owls due to bioaccumulation of rodenticides.
+
+
+=== Interspecific predatory relationships ===
+
+Due to their very broad dietary habits, the great horned owls share their prey with many other predators, including avian, mammalian and reptilian ones. Almost every study comparing the diets of North American owls illustrates the considerable overlap in the dietary selection of these species, as all species, besides the primarily insectivorous varieties, rely on many of the same small rodent species for most of their diet, extending from the small northern saw-whet owl and eastern screech owl to the great horned and great grey owls.In a long-term study of a block of Michigan, all nine species of accipitrid, falcon and owl that stayed to breed there were found to be primarily dependent on the same two rodent genera, the meadow vole and the two common Peromyscus species. In the Great Basin, the owls share black-tailed jackrabbit and desert cottontail as the primary prey with golden eagles, red-tailed hawks and ferruginous hawks (Buteo regalis); all four species had diets with more than 90% of the biomass is made up of those lagomorphs. Of these, the great horned owl and golden eagle were able to nest most closely to one another because they had the most strongly dissimilar periods of activity. In California, when compared to the local red-tailed hawks and western diamondback rattlesnakes (Crotalus atrox), the diets were most similar in that by number about 15-20% of all three species' diets depended on cottontails, but the largest portion was made up of ground squirrels in the hawk and the rattlesnake and desert woodrats and other assorted rodents in the great horned owl. In the boreal forests, the great horned owl's prolificacy as a snowshoe hare hunter places it second only to the Canada lynx (Lynx canadensis) among all predators. Although locally dependent on the hares as their main food, northern goshawks (Accipiter gentilis), red-tailed hawks and golden eagles apparently do not have as large of an impact on the hares, nor do mammalian carnivore generalists that also kill many hares, like the fisher, bobcat, wolverine (Gulo gulo), coyote and larger varieties (i.e. wolves (Canis lupus), cougars (Puma concolor) and bears (Ursus ssp.)).The relationship between great horned owls and other raptorial birds in its range is usually decidedly one-sided. While certain species, such as the red-tailed hawk and northern goshawk, might be seen as potential competition for the owls, most others seem to be regarded merely as prey by great horned owls. The great horned owl is both the most prolific and diverse predator in America of other birds of prey, with other accomplished raptor-hunters such as the goshawk and the golden eagle being more restricted in range, habitat and number in North America and thus having a more minor impact. All studies have found raptors are a small portion of this owl's diet but predation can be seriously detrimental for such prey, as raptors tend to be territorial and sparsely distributed as a rule and thus can be effectively decimated by a small number of losses. In the gray hawk (Buteo plagiatus), for example, in a study of one breeding block of Arizona, the owls were observed to visit nests nightly until all the nestlings were gone.Raptorial birds in general tend to have large, conspicuous nests which may make them easier for a hunting owl to locate. The great horned owl gains an advantage by nesting earlier than any other raptor in its range (indeed any bird), as it is able to exploit the other raptors as food while in a more vulnerable state as their own nestlings have become well developed. On average, great horned owls begin nesting about three weeks before red-tailed hawks begin to build nests, although some raptors may locally breed as much as two months after the owls.More so than diurnal varieties of raptor, fairly significant numbers of owls are hunted, as all species are to some extent nocturnal and thus their corresponding activity can attract the horned owl's unwanted attention. The extent of predation on other owls depends on the habitat preferences of the other species. Eastern and western screech owls may be most vulnerable since they prefer similar wooded edge habitat. In a block of Wisconsin, great horned owls were responsible for the failure of 78% of eastern screech owl's nests. Long-eared owls and, to a lesser extent, barn owls tend to hunt in open, sparsely treed habitats more so than great horned owls, but since they may return to wooded spots for nesting purposes, they may be more vulnerable there. The long-eared owl and barn owls are often compared to the great horned owl as these medium-sized species often occur in abutting habitats and often hunt primarily the same vole and mice species, although the alternate prey of the great horned tends to be much larger, including the smaller owls themselves. In a pair of studies from Colorado, the average weight of prey for long-eared owls was 28 to 30 g (0.99 to 1.06 oz), 46 to 57.1 g (1.62 to 2.01 oz) for barn owl and 177 to 220 g (6.2 to 7.8 oz) for the great horned owl.Both young and adult great grey owls, despite their superficially superior size, are apparently hunted with impunity by great horned owls. In the boreal forests, both the northern hawk owl and great grey owl appear to be in greater danger of great horned owl predation in years where the snowshoe hare have low populations. Great horned owls were the leading cause of mortality in juvenile spotted owls (30% of losses) and juvenile great grey owls (65% of losses). Less is known about relations with the snowy owl, which may compete with great horned owls for food while invading south for the winter. Anecdotally, both snowy and great horned owls have rarely been reported to dominate or even kill one another depending on the size and disposition of the individual owls, although the snowy's preference for more open areas again acts as something of a buffer. The snowy may be the one North American owl too formidable for the great horned owl to consider as prey.Whereas owls of any age are freely attacked by great horned owls whether nesting or not, when it comes to diurnal raptors, great horned owls are mainly a danger around the nest. They often hunt diurnal raptors when they come across their often relatively conspicuous active platform nests during hunting forays in spring and summer, taking numbers of both nestlings and brooding adults. Again, like owls, diurnal raptors are attacked depending on the relative similarity of their habitat preferences to the owl. Cooper's hawks (Accipiter cooperii) and red-tailed hawks tend to be most vulnerable, as they prefer the same wooded edges frequented by great horned owls. Other diurnal raptors may be attracted to more enclosed wooded areas, such as sharp-shinned hawks (Accipiter striatus) or zone-tailed hawks (Buteo albonotatus), or more open plain and meadow areas, such as Northern harriers (Circus hudsonius) and ferruginous hawks, but this is almost never a total insurance against predation as all of these are recorded prey.In a study of red-shouldered hawk (Buteo lineatus) and broad-winged hawk (Buteo brachyurus) breeding in New York, despite their nesting in deeper woods than those that host these owls, the main cause of nest failure was great horned owl predation. Similarly, the great horned owl was the primary cause of nesting failure for both desert-dwelling Harris's hawks (Parabuteo unicinctus) and forest-dwelling northern goshawk in Arizona (39% and 40% of failures, respectively), wetland-inhabiting osprey (Pandion haliaetus) in Delaware (21% of failures) and peregrine falcons (Falco peregrinus) in the Western United States (27% of failures). The fact that many of the nests great horned owls use are constructed by accipitrids may lead to localized conflicts, almost always to the detriment of the hawks rather than the owls. While the young of larger diurnal raptors are typically stolen in the night, great horned owls also readily kill large adult raptors both in and out of breeding seasons, including osprey, northern goshawk and rough-legged buzzard.Great horned owls are frequently mobbed by other birds. Most accipitrids will readily mob them, as will falcons. Hen harriers, northern goshawks, Cooper's hawks, Harris's hawks, red-tailed hawks, Swainson's hawks, ferruginous hawks, red-shouldered hawks, American kestrels, peregrine falcons, prairie falcons (Falco mexicanus) and common ravens (Corvus corax) are among the reported species who have been recorded diving on great horned owls when they discover them. In Arizona and Texas, they may be mobbed by Mexican jays and western scrub jays (Aphelocoma wollweberi & californica) and western and Cassin's kingbirds (Tyrannus verticalis & vociferans). In addition, there are several documented incidences of American crows mobbing a great horned owl, in groups of dozens or even hundreds of crows. In response to mobbing, if the owl flies it alights to the nearest secluded spot. If an owl alights on ground or on exposed branch or ledge, it may respond to swooping and stooping flights of corvids and raptors with threat display and raising of its wings.

+
+== Reproduction ==
+
+Great horned owls are some of the earliest-breeding birds in North America, seemingly in part because of the lengthy nightfall at this time of year and additionally the competitive advantage it gives the owl over other raptors. In most of North America, courtship is from October to December and mates are chosen by December to January. This species was once thought to be strictly monogamous, but recent analysis indicates one male may mate with two females simultaneously, as was discovered for the first time in 2018 in Reno, Nevada. During courtship in late fall or early winter, the male attracts the attention of his mate by hooting emphatically while leaning over (with the tail folded or cocked) and puffing up his white throat to look like a ball. The white throat may serve as a visual stimulus in the low light conditions typical of when this owl courts. He often flies up and down on a perch, while approaching the potential mate. Eventually, he comes to approach the female and tries to rub his bill against hers while repeatedly bowing. If receptive, the female hoots back when the pair meet but is more subdued in both her hoot and display. The male may convince the female by bringing her freshly caught prey, which they will share. While males often hoot emphatically for about a month or six weeks towards the end of the year, the period where females also hoot is usually only a week to ten days. Pairs typically breed together year after year and may mate for life, although they associate with each other more loosely when their young become mostly independent. Pairs rekindling their reproductive relationship in the winter may perform a milder courtship to strengthen pair bonds before producing young.Males select nesting sites and bring the females' attention to them by flying to the nest and then stomping on it. Considering the owls' large size, nests with open access are preferred to those enclosed with surrounding branches. Like all owls, great horned owls do not build their own nest. Great horned owls tend to examine an area for an abandoned nest, generally from larger birds like hawks, and take over the nest for raising their own young. They nest in a wider variety of sites than any other North American bird. Many nests are in cavernous hollows of dead trees or their branches, and especially in southern states in large trees along the edge of old-growth lots. In mountainous or hilly areas, especially in canyons of the Southwest and Rocky Mountains, cliff ledges, small caves, and other sheltered depressions may be used. Owls living in prairie country, in the absence of other animals' nests, riparian tree-hollows or man-made structures, will use boulders, buttes, railroad cuts, low bushes and even the bare ground as nest sites. Ground nests have also been recorded in the midst of tall grasses in Florida and in the midst of brushy spots on desert ground. Even the burrow entrances of American badger and coyote dens have reportedly been used as nests, in spite of the inherent risk of sharing space with such potentially dangerous co-inhabitants. Nesting behavior for the great horned owl appears to be more closely related to prey availability than it does to seasonal conditions. There has been some evidence that if prey availability is low enough then the species may forgo mating entirely for a season. Male and female owls of the species have been observed to help incubate the eggs once they have been laid on a nest.
+
+Most tree nests used by great horned owls are constructed by other animals, often from a height of about 4.5 to 22 m (15 to 72 ft) off the ground. They often take over a nest used by some other large bird, sometimes adding feathers to line the nest but usually not much more. Allegedly there have some cases where the owls have reinforced a nest structure or appeared to have reconstructed a nest, but as a rule no owl species has ever been known to actually build a nest. Great horned owls in the Southwest may also use nests in cacti, built by Harris's hawk and red-tailed hawk, as well as large hollows in cacti. The nests they use are often made by most larger types of acciptrids, from species as small as Cooper's hawks to bald eagle and golden eagle, though perhaps most often those of red-tailed hawks and other buteonines. Secondly in popularity are crow and raven (Corvus ssp.) nests. Even Canada goose, black-crowned night heron (Nycticorax nycticorax) and great blue heron nests have been used, the latter sometimes right in the midst of an active heronry. The leaf nests of squirrels are also regularly used but in general great horned owls are partial to stick nests since they provide a much firmer, safer foundation.The stage at which eggs are laid is variable across North America. In Southern Florida, eggs may be laid as early as late November to as late as early January. In the southeast, from south Texas to Georgia, egg laying may begin from late December to early February. From Southern California to northern Louisiana, egg laying is from early February to late March. The largest swath of egg-laying owls from central California to South Carolina to as far north as Ohio and Massachusetts is from late February to early April. In the Rocky Mountains, Northwestern United States, northern New England and eastern Canada, egg laying is from early March to late April. In the rest of Canada and Alaska, egg laying may be from late March to early May. The latest known date of egg laying was in mid-June in Saskatchewan and the Yukon Territory. In northwestern Utah and north-central Alberta, egg-laying can be 3–4 weeks earlier than usual when food is abundant and weather is favorable. For owls found in more tropical climates, the dates of the breeding season are somewhat undefined. There are usually 2 eggs per clutch, but clutches range in size from 1 to 6 eggs (over 3 is uncommon, over 4 is very rare), depending on environmental conditions. The average egg width is 46.5 mm (1.83 in), the average length is 55 mm (2.2 in) and the average weight is 51 g (1.8 oz), although mass could be slightly higher elsewhere because this figure is from Los Angeles County, CA where the owls are relatively small. The incubation period ranges from 28 to 37 days, averaging 33 days. The female alone usually does all the incubation and rarely moves from the nest, while the male owl captures food and brings it to her, with the first nightly food delivery typically occurring soon after dark.The young weigh 34.7 g (1.22 oz) at birth on average and can gain about 33 g (1.2 oz) a day for the first four weeks of life, with typical weights in the range of 800 or 1,000 g (1.8 or 2.2 lb) by 25–29 days for males and females, respectively. When first hatched the young are covered in whitish gray down, with some brownish about the wings. Gradually the soft juvenal downy plumage comes through the down, being typically a cinnamon-buff color, but with variable hues predicting the eventual color of the mature owls. The extent of down gradually diminishes, developing mature-looking plumage by late summer, although many first year birds still have scattered bits of down into autumn. By late autumn, first-year birds look similar to adults but with a slightly warmer, reddish tinge, less well developed ear tufts and a smaller white throat patch. The nestling owls develop mostly in behavior between two weeks and two months of age, in which time they adapt the ability to defend themselves, grasp foods and climb. Vocally, the young are able to exert weak chips while still in the egg, developing into a raspy chirp shortly after hatching. The calls of the young increase rapidly in intensity, pitch and character, some juvenile males mimicking their father's hooting in fall but usually they conclude with various odd gurgling notes. The earliest competent hooting by juvenile owls is not until January. Young owls move onto nearby branches at 6 weeks and start to fly about a week later. However, the young are not usually competent fliers until they are about 10 to 12 weeks old. The age at which the young leave the nest is variable based on the abundance of food.The young birds stay in an area ranging from 13 to 52 ha from the nest into fall, but will usually disperse up to several thousand hectares by the end of fall. The offspring have been seen still begging for food in late October (5 months after leaving the nest) and most do not fully leave their parents territory until right before the parents start to reproduce for the next clutch (usually December to January). Birds may not breed for another year or two, and are often vagrants ("floaters") until they establish their own territories. Based on the development of the bursa, great horned owls reach sexual maturity at two years of age.
+
+
+=== Urban vs rural nesting ===
+While urban and rural populations show little difference in productivity, there are differences in nest selection.  Rural owls use old raptor nests more frequently than urban birds, who utilize crow or squirrel nests. Additionally, urban nesting individuals utilize trees that are taller/wider in diameter and nest much higher compared to rural nesting Great Horned Owls. The reason behind this increased tree height is due to the fact that urban areas have large trees used for ornamentation, shade and shelter. The higher nesting within the taller trees was attributed to human avoidance. Both rural and urban nesting sites were often within range of paved roads, likely a result of the great horned owl’s tendency to hunt along roadwaysStudies have shown that nesting in urban areas can influence adult great horned owls to lay eggs earlier than those who nest in rural areas. In Wisconsin, eggs in urban nests hatched a month earlier (January rather than February) than their counterparts in rural areas, probably due to increased protection from wind and cold. Nesting owls at sites in Winnipeg, Manitoba began nesting five to six weeks earlier than those in rural parts of Manitoba, presumably due to experiencing an extremely warm winter by Winnipeg’s standards, as well as benefitting from the local urban heat island.

+== Mortality and longevity ==
+
+
+=== Longevity and natural mortality ===
+Great horned owls seem to be the most long-living owl in North America. Among all owls, they may outrank even the larger Eurasian eagle owl in known longevity records from the wild, with almost 29 years being the highest age for an owl recorded in North America. In captivity, the record for the longest lived great horned owl was 50 years. A more typical top lifespan of a great horned owl is approximately 13 years. In general, great horned owls are most vulnerable in the early stages of life, although few species press attacks on the owl's nests due to the ferocious defensive abilities of the parents. Occasionally, nestlings and fledglings will fall from the nest too early to escape or to competently defend themselves and fall prey to foxes, bobcat, coyotes, or wild or feral cats. Occasionally raccoons and American black bears consume eggs and nestlings from tree nests and Virginia opossum may take the rare unguarded egg. Crows and ravens have been reported eating eggs and small nestlings. This can normally only happen when owls are driven from the nest by human activity or are forced to leave the nest to forage by low food resources but on occasion huge flocks of crows have been able to displace owls by harassing them endlessly. In general, great horned owls rarely engage in siblicide, unlike many other raptorial birds. Siblicide occurred at 9 of 2,711 nests in Saskatchewan. Most cases where young owls are killed and/or consumed by their siblings or parents appear to occur when the nestling is diseased, impaired or starving or is inadvertently crushed. Adults generally have no natural predators, excepting both North American eagles and other owls of their own species.Occasionally, great horned owls may be killed by their own prey. Although typically able to kill skunks without ill effect, five owls were found blind after getting sprayed in their eyes by skunks. Cases where the quills of porcupines have killed or functionally disabled them have been observed as well. Violent fights have been observed between great horned owls after attempts to capture rat snakes and black racers. When a peregrine falcon repeatedly attacked a great horned owl near its nest along the Hudson River, it was apparently unable to dispatch the larger raptor despite several powerful strikes. During their initial dispersal in fall, juvenile owls have a high mortality rate, frequently more than 50%. For owls in the Yukon Territory, juvenile survival in the 9 weeks after dispersal has dropped from 80% to 23.2% in a span of three years in response of instability of food supply. In the Yukon, adults on territory had an average annual survival rate of 90.5%. Anemia, caused by Leucocytozoon ziemanni and the drinking of blood by swarming, blood-drinking blackflies (Simulium ssp.), was a leading cause of juvenile mortality in the Yukon.
+
+
+=== Human-related mortality ===
+The great horned owl is not considered a globally threatened species by the IUCN. Including the Magellanic species, there are approximately 5.3 million wild horned owls in the Americas. Most mortality in modern times is human-related, caused by owls flying into man-made objects, including buildings, cars, power lines, or barbed wire. In one study, the leading cause of death for owls was collision with cars, entanglement with wires, flying into buildings and, lastly, electrocution. Among 209 banded nestlings in yet another study, 67% were found dead after independence: 56 were found shot, 41 were trapped, 15 hit by cars, 14 found dead on highways and 14 electrocuted by overhead power lines. Secondary poisoning from pest control efforts is widely reported variously due to anticoagulant rodenticides, strychnine, organophosphates (famphur applied topically to cattle (Bos primigenius taurus)), organochlorines, and PCBs.Frequently, the species were denominated a pest due to the perceived threat it posed to domestic fowl and potentially small game. The first genuine nature conservationists, while campaigning against the "Extermination Being Waged Against the Hawks and Owls", continued to advocate the destruction of great horned owls due to their predatory effect on other wildlife. Thus, small bounties were offered in trade for owl bodies. Around the turn of the 20th century, the great horned owl was considered endangered in the state of Michigan because of the large number of poachers who were illegally hunting and collecting it. Hunting and trapping of great horned owls may continue on a small scale but is now illegal in most countries.
+
+
+=== Effect on conservation-dependent species ===
+Occasionally, these owls may prey on threatened species. Following the devastation to its populations from DDT, the reintroduction of the peregrine falcon to the Mississippi and Hudson Rivers was hampered by great horned owls killing both young and adult peregrines at night. Similarly, as mainly recorded in New England, attempts to reintroduce ospreys, after they were also hit hard by DDT, were affected by heavy owl predation on nestlings, and the owls were also recorded to take a large toll locally on the threatened colonies of roseate terns. Where clear-cutting occurs in old-growth areas of the Pacific Northwest, spotted owls have been badly affected by considerable great horned owl predation. While at least the ospreys and peregrines have rebounded admirably nonetheless, bird and mammal species that are much rarer overall sometimes fall prey to great horned owls, many in which even sporadic losses can be devastating. Among the species considered threatened, endangered or critically endangered by the IUCN which are also known to be killed by great horned owls are Townsend's ground squirrels (Urocitellus townsendii), Pacific pocket mice (Perognathus pacificus), giant kangaroo rats, Stephens' kangaroo rat (Dipodomys stephensi), black-footed ferrets, greater and lesser prairie chickens, marbled murrelets (Brachyramphus marmoratus), ivory-billed woodpeckers, Florida scrub jays (Aphelocoma coerulescens), pinyon jays, Kirtland's warblers (Setophaga kirtlandii) and rusty blackbirds (Euphagus carolinus). The American Bird Conservancy's "green list" includes birds with considerable population declines (many classed as near threatened by the IUCN) or other immediate threats and/or restricted populations. Altogether, great horned owls hunt 50 different species from that list.
+
+
+== Iconography and myth ==
+Many warrior-based tribes of Native Americans admired the great horned owl for their "strength, courage and beauty". The Pima of the Southwest believed that owls were reincarnations of slain warriors who fly about by night. The Arikara of the Great Plains had mystic owl societies in which initiates were made to adorn a facial mask made of the wing and tail feathers of great horned owls. Some Indian nations regarded the great horned owl as a friendly spiritthat could aid in matters of love, such as the Passamaquoddy of Maine, who felt the call of this species was a magical love flute designed to ignite human passions. The Hopi of the Southwest also associated this owl with fertility, albeit of a different kind: they believed the calling of the owls into summer predicted hot weather, which produced good peach crops. During the winter solstice, the Hopi performed a ceremony with great horned owl feathers in hopes of summoning the heat of summer. Tribes in New Mexico were known to use owl wing-feathers to produce arrows which could strike their enemies with a minimum of sound. The Zuni held owl feathers in their mouths hoping to gain some of the silence that owls use in ambushes while striking their own enemies from other tribes. The Iroquois felt the origin of the great horned owl was due to an unformed owl annoying Raweno, the almighty creator, while Raweno created the rabbit, causing Raweno to make the owl "covered with mud" (dark camouflage) and doomed to ceaselessly call "whoo whoo", which he used while harassing Raweno by night because Raweno was active during the day.

+The Abyssinian ground hornbill or northern ground hornbill (Bucorvus abyssinicus) is an African bird, found north of the equator, and is one of two species of ground hornbill. It is the second largest species of African hornbill, only surpassed by the slightly larger southern ground hornbill.
+
+
+== Taxonomy ==
+The Abyssinian ground hornbill was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1780 in his Histoire Naturelle des Oiseaux. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text.  Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Buceros abyssinicus in his catalogue of the Planches Enluminées. The type locality is Ethiopia. The Abyssinian ground hornbill is now placed in the genus Bucorvus that was introduced, originally as a subgenus, by the French naturalist René Lesson in 1830. The species is monotypic. The generic name is derived from the name of the genus Buceros introduced by Carl Linnaeus in 1758 for the Asian hornbills where corvus is the Latin word for a "raven".
+
+
+== Description ==
+Abyssinian ground hornbill is a large, terrestrial hornbill with black body feathers and white primary feathers which are visible in flight.  The adult male has a patch of bare blue skin around the eye and an inflatable patch of bare skin on the neck and throat which is red, apart from the upper throat which is blue. The bill is long and black except for a reddish patch at the base of the mandible. On top of the bill there is a short open-ended black casque. The female is similar but smaller with any bare skin being wholly dark blue. Juvenile birds are dark sooty-brown with a smaller bill, with an incipient casque. As the juvenile matures, which usually takes 3 years, it gradually develops the plumage, bare skin colour and casque of the adults.  The total length is 90 to 110 cm (35 to 43 in).The Abyssinian ground hornbill has long feathers that look like eyelashes that surround its eyes. These protect the eyes from injury.It reportedly averages around 90 to 100 cm (35 to 39 in) tall, around 110 cm (43 in) and weighs approximately 4 kg (8.8 lb). Per Stevenson and Fanshawe, the Abyssinian is a larger species on average than the southern ground hornbill, at 102 cm (40 in), but published weights and standard measurements contrarily indicate the southern species is indeed slightly larger.
+
+
+=== Voice ===
+A deep booming uh-uh, uh-uh-uh which is far carrying and is normally made at dawn from either a perch or from the ground. The male and female sing in duets.
+
+
+== Distribution and habitat ==
+
+The Abyssinian ground hornbill is found in Northern sub-Saharan Africa from southern Mauritania, Senegal and Guinea east to Eritrea, Ethiopia, north western Somalia, north western Kenya and Uganda.It is found in open habitats such as savanna, sub-desert scrub, and rocky areas, preferring short vegetation which enables its visual foraging technique. The areas inhabited by this species are usually drier areas than the preferred habitat of the Southern ground hornbill. It will tolerate disturbed areas but does require large trees to be used as nest sites.The Abyssinian ground hornbill has escaped or been deliberately released in to Florida, USA, but there is no evidence that the population is breeding and may only persist due to continuing releases or escapes.
+
+
+== Behaviour ==
+The Abyssinian ground hornbill lives in open grassland, in pairs or small family parties. They patrol their territory by walking and are reluctant fliers, usually only taking to the air when alarmed. In captivity, they can live 35–40 years. Diet in the wild consists of a wide variety of small vertebrates and invertebrates, including tortoises, lizards, snakes, birds, spiders, beetles, and caterpillars; they also take carrion, some fruits, seeds, and groundnuts. Groups of ground hornbills have territories of 2–100 square miles (5.2–259.0 km2). They are diurnal.
+
+
+=== Breeding ===
+The breeding season of the Abyssinian ground hornbill varies across its range: the West African populations breed in June through to August, Nigerian and Ugandan populations breed in January, and Kenyan birds breed as late as November. They prefer to nest in large trees, with baobabs and palm stumps being preferred; the nest is constructed in a cavity. They have also been recorded nesting in other types of cavities including holes in rocks and man-made cavities such as bee-hive logs or baskets. In the ground hornbills the females are partially sealed in using a mixture of mud and vegetation. In other hornbills the nesting female moult their all flight feathers at once but this is not the case in the ground hornbills. The male prepares the nest by lining the cavity with dry leaves before the female enters and lays a clutch of one or two eggs over around five days. She starts to incubate as soon as the first egg is laid so that the chick which hatches first has a head start in development over its sibling. Incubation of each egg takes between 37 and 41 days, during which time there is no effort to keep the cavity clean and the male is responsible for providing food to the incubating female. The weight of the newly hatched chick is around 70 g (2.5 oz) and the first-hatched grows rapidly at the expense of the second, which will normally die of starvation before it is four days old by which time its sibling can weigh as much as 350 g (12 oz). When the surviving chick is 21 to 33 days old the mother leaves the nest and starts to help in food provision, then after 80 to 90 days the chick leaves the nest.Abyssinian ground hornbills invest a lot in their offspring and the fledged juveniles will remain with their parents for up to three years. They have a slow breeding rate and an average of one chick is raised to adulthood every 9 years so the adults' investment in each young bird raised is exceptionally high.
+
+
+=== Feeding ===
+Abyssinian ground hornbills are opportunist feeders, following ungulate herds and forest fires so that they can prey on small animals disturbed by the larger animals or flames. An individual hornbill can walk up to 11 km (6.8 mi) in a day, pouncing on and eating animals they come across. They have also been recorded digging for arthropods in the soil and attacking bee hives for honeycomb; they very rarely consume any plant matter. The strong bill is used to capture and overcome the prey before it is eaten.
+
+
+== Predators, parasites and diseases ==
+Abyssinian ground hornbills are preyed on by large carnivores, such as leopards. Human predation for food occurs in some countries, including northern Cameroon and Burkina Faso. The nests may be preyed upon by smaller terrestrial predators.
+The Abyssinian ground hornbill is a known host for the bird lice Bucorvellus docophorus, Bucerophagus productus and Bucerophagus africanus; it is also a host for the nematode Histiocephalus bucorvi and the tapeworms Chapmania unilateralis, Idiogenes bucorvi, Ophryocotyloides pinguis, and Paruterina daouensis. An individual held in captivity but which had been caught in the wild died from an infection of the bacteria Aeromonas hydrophila, a common pathogen in fish but not previously recorded in wild Abyssinian ground hornbills. In North America captive Abyssinian ground hornbills have also been known to die because of West Nile virus.
+
+
+== Cultural importance ==
+Abyssinian ground hornbills are not a normal quarry for commercial hunters, although they are not uncommon in captivity in zoos. In some areas the species has cultural significance and hunters may tie the severed head and neck of these birds around their necks in the belief that it helps them stalk their wild ungulate quarry. In some villages the call is often imitated and there are even entire songs based on the male and female duets of Abyssinian ground hornbills.
+
+
+== Status and conservation ==
+The Abyssinian ground hornbill is subject to the loss and degradation of its habitat and it is a quarry of hunters, in a similar way to its congener, the Southern ground hornbill, and, as a result, it is thought that the population may have started a rapid decline. As a result of this perceived decline the IUCN give its status as Vulnerable.

+The Eleonora cockatoo, Cacatua galerita eleonora, also known as medium sulphur-crested cockatoo, is a subspecies of the sulphur-crested cockatoo. It is native to the Aru Islands in the province of Maluku in eastern Indonesia, but has also been introduced to Kai Islands. It is common in aviculture.
+The Eleonora cockatoo was named by Otto Finsch. He discovered the subspecies in Amsterdam's Artis zoo and named it after Maria Eleonora van der Schroef, the wife of the then director of the zoo. This subspecies was accepted by Gerlof Mees in 1972 and Joseph Forshaw (1989) and recognised by Edward C. Dickinson and James Van Remsen Jr. (2013).
+
+
+== Characteristics ==
+
+It is the smallest of the four subspecies of Cacatua galerita, at approx. 44 cm (17 in) long and weighing between 404–602 g (14–21 oz). Apart from the size difference, the Eleonora differs from the greater sulphur crested in that it doesn't have as prominent white eyerings (they often are a pale blue), the crest of an Eleonora is often less curved and it doesn't have the pointy upper mandible, which is only found in Cacatua galerita galerita. Although a smaller and lighter bird, in practice it may be difficult to differentiate this subspecies from the Triton cockatoo.The Eleonora cockatoo often has pale yellow ear patches, and yellow diffusion throughout the body, especially under the wings and tail. The Eleonora also has a bald patch behind its crest.
+
+
+== Diet and habitat ==
+In the wild, the Eleonora cockatoo is found in open woodlands, forests, and semi-arid forested areas, as well as partially cleared forest areas. It feeds on nuts, berries, flower buds, flowers, seeds and insects.
+
+
+== Reproduction ==
+The breeding season of this cockatoo is mainly from September to January. The birds build their nests in a tree hollow or rock crevice. The female lays 2–3 white oval eggs, which hatch after a period of 30 days. Both parents incubate the eggs and in turn provide for the chicks. The young fledge after about 75 days.
+
+
+== Intelligence and beat perception ==
+One notable Eleonora cockatoo is Snowball, a bird recently demonstrated to be capable of beat induction – in other words, that the bird is capable of perceiving a musical beat and dancing to it.Like all cockatoos, the Eleonora cockatoo is widely considered to be very intelligent and emotionally complex.

+The sulphur-crested cockatoo (Cacatua galerita) is a relatively large white cockatoo found in wooded habitats in Australia, New Guinea, and some of the islands of Indonesia. They can be locally very numerous, leading to them sometimes being considered pests. A highly intelligent bird, they are well known in aviculture, although they can be demanding pets.
+
+
+== Distribution ==
+In Australia, sulphur-crested cockatoos can be found widely in the north and east, ranging from the Kimberley to as far south as Tasmania, but avoiding arid inland areas with few trees. They are numerous in suburban habitats in cities such as Adelaide, Melbourne, Canberra, Sydney and Brisbane. Except for highland areas, they occur throughout most of New Guinea and on nearby smaller islands such as Waigeo, Misool and Aru, and various islands in the Cenderawasih Bay and Milne Bay.
+There are four recognised subspecies:
+
+
+=== Introduced species ===
+Within Australia, sulphur-crested cockatoos of the nominate race have also been introduced to Perth, which is far outside the natural range. Outside Australia, they have been introduced to Singapore, where their numbers have been estimated to be between 500 and 2000. They have also been introduced to Palau and New Zealand. In New Zealand, the introduced populations may number less than 1000. This species has also been recorded as established in Hawaii and from various islands in Wallacea (e.g. Kai Islands and Ambon), but it is unclear if it has managed to become established there.
+
+
+== Description ==
+
+Sulphur-crested cockatoos are 44–55 cm (17.5–21.5 in) long, with the Australian subspecies larger than subspecies from New Guinea and nearby islands. The plumage is overall white, while the underwing and -tail are tinged yellow. The expressive crest is yellow. The bill is black, the legs are grey, and the eye-ring is whitish. Males typically have almost black eyes, whereas the females have a more red or brown eye, but this requires optimum viewing conditions to be seen. The differences between the subspecies are subtle. C. g. fitzroyi is similar to the nominate race but lacks the yellow on the ear tufts and has slightly blueish skin around the eye. C. g. eleonora is similar to  C. g. fitzroyi but is smaller and has broader feathers in the crest, and C. g. triton is similar to C. g. eleonora except it has a smaller bill.It is similar in appearance to the three species of corellas found in Australia. However, corellas are smaller, lack the prominent yellow crest and have pale bills. In captivity, the sulphur-crested cockatoo is easily confused with the smaller yellow-crested cockatoo or the blue-eyed cockatoo with a differently shaped crest and a darker blue eye-ring.
+
+
+== Behaviour ==
+
+Sulphur-crested cockatoos' distinctive raucous calls can be very loud, which is a result of an adaptation in order to travel through the forest environments in which they live, including tropical and subtropical rainforests. These birds are naturally curious, as well as very intelligent. They have adapted very well to European settlement in Australia and live in many urban areas.
+Being intelligent, in Sydney, Australia they have learned how to open garbage bins as a source of food. The behavior spreads among the birds by imitation. In captivity some will spontaneously dance to music with a variety of unique moves.These birds are very long-lived, and can live upwards of 70 years in captivity, although they only live to about 20–40 years in the wild. They have been known to engage in geophagy, the process of eating clay to detoxify their food. These birds produce a very fine powder to waterproof themselves instead of oil as many other birds do.
+The sulphur-crested cockatoo is a seasonal breeder in Australia; little is known about its breeding behaviour in New Guinea. In southern Australia the breeding season is from August to January, whereas in northern Australia the season is from May to September. The nest is a bed of wood chips in a hollow in a tree. Like many other parrots it competes with others of its species and with other species for nesting sites. Two to three eggs are laid and incubation lasts between 25–27 days. Both parents incubate the eggs and raise the nestlings. The nestling period is between 9 and 12 weeks, and the young fledglings remain with their parents for a number of months after fledging.Sulphur-crested cockatoos have range of visually observable expressions. A 2009 study involving an Eleonora cockatoo (the subspecies Cacatua galerita eleonora) named Snowball found that sulphur-crested cockatoos are capable of synchronizing movements to a musical beat. Sulphur-crested cockatoos use facial expressions (with their feathers) to indicate positive emotions.Species that feed on the ground are very vulnerable to predator attack. The cockatoo has evolved a behavioural adaptation to protect against this: whenever there is a flock on the ground, there is at least one high up in a tree (usually a dead tree), keeping guard. This is so well known that it has even entered Australian slang: a person keeping guard for sudden police raids on illegal gambling gatherings is referred to as a cockatoo or cocky for short.
+
+
+== Pest status ==
+
+In some parts of Australia, sulphur-crested cockatoos can be very numerous, and may cause damage to cereal and fruit crops and newly planted tree seedlings, as well as soft timber on houses and outdoor furniture. Consequently, they are sometimes shot or poisoned as pests. A government permit is required for any culling, because the birds are a protected species under the Australian Commonwealth Law.
+
+
+== Aviculture ==
+Sulphur-crested cockatoos may no longer be imported into the United States as a result of the Wild Bird Conservation Act (WBCA). However, they have been bred in captivity, with Eleonora and Triton cockatoos the most common subspecies seen in aviculture in the USA and Europe. They are socially demanding pets and have a natural desire to chew wood and other hard and organic materials. They are also loud, often unleashing loud squawks or piercing screeches. They may also make aggressive, unpredictable movements which can frighten people and animals unaware of the accompanying affection.
+One cockatoo called Fred was still alive at 100 years of age in 2014. Cocky Bennett of Tom Ugly's Point in Sydney was a celebrated sulphur-crested cockatoo who reached an age of 100 years or more. He had lost his feathers and was naked for much of his life, and died in the early years of the twentieth century. His body was stuffed and preserved after death. Another 'cocky', born in 1921 and residing in Arncliffe with his owner Charlie Knighton, was 76 years old in the late 1990s.Sulphur-crested cockatoos, along with many other parrots, are susceptible to psittacine beak and feather disease, a viral disease, which causes birds to lose their feathers and grow grotesquely shaped beaks. The disease occurs naturally in the wild, and in captivity.

+The little corella (Cacatua sanguinea), also known as the short-billed corella, bare-eyed cockatoo, blood-stained cockatoo,  and little cockatoo is a white cockatoo native to Australia and southern New Guinea. It was known as Birdirra among the Yindjibarndi people of the central and western Pilbara. They would keep them as pets, or traditionally cook and eat them. The downy feathers are used in traditional ceremonies and dances where they adorn head and armbands.
+
+
+== Taxonomy ==
+
+The first recorded description of the species was by English ornithologist John Gould in 1843. There are four subspecies as follows:
+C. s. sanguinea
+C. s. normantoni
+C. s. transfreta
+C. s. gymnopis
+C. s. westralensis (Mathews 1917)
+
+
+== Description ==
+
+The little corella is a small white cockatoo growing to 35–41 cm (14–16 in) in length and weighs 370–630 g (13–22 oz), with a mean weight of 525 g (1.157 lb). It is similar in appearance to both the long-billed corella and the western corella, but the little corella is smaller, and unlike either of those species, it has upper and lower mandibles of similar length. It is easily distinguished from the long-billed corella by the lack of an orange throat bar. C. s. normantoni and C. s. normantoni are a little smaller than the nominate form. C. s. normantoni is lightly brownish on the underside of flight and tail feathers. C. s. gymnopis has darker blue eye-rings, more strongly marked pink lores and a yellow wash to the lower-ear coverts. Females are slightly smaller than males in weight, wing length, culmen size, tarsus length, tail length and eye ring diameter.
+
+
+== Distribution and habitat ==
+The nominate form, C. s. sanguinea is found in Northern Australia. C. s. normantoni is found on the Western Cape York Peninsula. C. s. transfreta is found in New Guinea. C. s. gymnopis is found in Central, Eastern, and South-eastern Australia. Habitat ranges from the arid deserts of central Australia to the eastern coastal plains, but they are not found in thick forests. Little corellas can also be found in urban areas, including Melbourne, Canberra, Sydney and Brisbane, where they feed on lawns and playing fields. They are numerous in farmlands throughout New South Wales and Queensland, and have become so common in some areas that they are considered to be crop pests, and can be destructive to the trees in which they perch, by chewing the bark off smaller twigs.
+
+
+== Behaviour ==
+Little corellas congregate in flocks of up to several thousand, which often include other birds such as galahs, sulfur-crested cockatoos and red-tailed black cockatoos. They generally roost in trees overnight, and fly off to feed in the early morning before returning in the late evening. Flocks will often fly many kilometers between their feeding and roosting areas, and in desert areas must also fly to watering holes twice a day, while corellas which live in coastal areas do not have to fly long distances to find water.
+
+
+=== Call ===
+The call consists of high pitched notes and screeches somewhat similar to the sulfur-crested cockatoo. Large flocks will call simultaneously and can create a deafening screeching sound audible from several kilometers away.
+
+
+=== Breeding ===
+
+Breeding occurs from May to October, and usually takes place earlier in the north of its range. The nest is usually in a tree hollow, cliff cavity or termite mound.
+
+
+=== Feeding ===
+Little corellas usually feed on the ground, however occasionally feed in trees and shrubs. They eat a variety of both wild and cultivated seeds and regularly feed on lawn grasses in urban areas. They frequently feed on cereal crops such as wheat, barley and maize and can become a considerable agricultural pest in some areas.
+
+
+=== Playing ===
+When little corellas play, they become very noisy. They have conversations with each other, fly around and also show off. Little corellas show off by hanging themselves upside-down with their feet, beaks or both.
+
+
+== Relationship to humans ==
+In Australia, little corellas are considered "unprotected native fauna" and may be shot (without a permit), trapped or gassed (with a permit) by landowners. Permits are also available to take a limited number of little corellas from the wild each year for avicultural purposes.
+
+
+== Threats ==
+In July 2019, in a scene that was said to resemble a "horror movie", about 60 corellas in Adelaide, South Australia, died in a suspected case of poisoning, after "falling from the sky", bleeding from their mouths, and wailing. At least 57 of the birds were long-billed corellas, with a few of them being were short-billed corellas. It was hoped that whoever poisoned them would get traced after doing a report on toxicology, which could nevertheless take several weeks to complete, because in Australia, people were required to register if they purchase poisons, according to Sarah King, founder of Casper's Bird Rescue, who witnessed the deaths, and also said that the type of poison was a slow one that takes several weeks to work. Additionally, the local Alexandrina council had beforehand called for short-billed corellas to be culled for damaging crops and chewing on streetlights, damaging built infrastructure such as buildings and sporting equipment, and displacing other native species of birds and bees, possums, and other organisms.

+The yellow-crested cockatoo (Cacatua sulphurea) also known as the lesser sulphur-crested cockatoo, is a medium-sized (about 34-cm-long) cockatoo with white plumage, bluish-white bare orbital skin, grey feet, a black bill, and a retractile yellow or orange crest. The sexes are similar.
+The yellow-crested cockatoo is found in wooded and cultivated areas of East Timor and Indonesia's islands of Sulawesi and the Lesser Sundas. It is easily confused with the larger and more common sulphur-crested cockatoo, which has a more easterly distribution and can be distinguished by the lack of pale yellow coloring on its cheeks (although some sulphur-cresteds develop yellowish patches). Also, the yellow-crested cockatoo's crest is a brighter color, closer to orange. The citron-crested cockatoo, which is a subspecies of the yellow-crested cockatoo, is similar, but its crest is clearly orange.The yellow-crested cockatoo's diet consists mainly of seeds, buds, fruits, nuts, and herbaceous plants.
+
+
+== Taxonomy ==
+
+According to the International Ornithological Congress, 6 subspecies have been recognized:
+C. s. sulphurea (nominate subspecies) (Gmelin, JF, 1788) – Sulawesi and nearby smaller islands
+C. s. abbotti (Abbott's yellow-crested cockatoo) (Oberholser, 1917) –  Masalembu Islands
+C. s. djampeana Hartert, E, 1897 – Tanah Jampea
+C. s. occidentalis Hartert, E, 1898 – Lesser Sundas from Lombok to Alor (thereby restricting C. p. parvula to Timor)
+C. s. parvula (Timor yellow-crested cockatoo) (Bonaparte, 1850) – Sumbawa, Komodo, Flores, Timor, and various other islands in the Lesser Sundas
+C. s. citrinocristata (citron-crested cockatoo) (Fraser, 1844) – SumbaPreviously, only 4 of these were recognized, but djampeana and occidentalis were recognized in 2022 based on a 2014 phylogenetic study. The subspecies paulandrewi, thought to be endemic to the Tukangbesi Islands and also recognized in the 2014 study, is not recognized by the IOC.
+
+
+== Breeding ==
+The yellow-crested cockatoo nests in tree cavities. The eggs are white and usually two in a clutch. The incubation is shared by both parents. The eggs are incubated for about 28 days and the chicks leave the nest about 75 days after hatching.
+
+
+== Status and conservation ==
+
+The yellow-crested cockatoo is critically endangered. Numbers have declined dramatically due to illegal trapping for the cage-bird trade. Between 1980 and 1992, over 100,000 of these birds were legally exported from Indonesia, yet a German proposal submitted to CITES to move it to Appendix I was not approved. It has since been moved to Appendix I. The current population is estimated at fewer than 2,500 individuals and is thought to be declining in number.The subspecies C. s. abbotti is found only on the island of Masakambing. Its population on this tiny island (about 5 km2 or 1.9 mi2) had fallen to 10 as of June and July 2008. The decline results from trapping and logging, especially of mangrove (Avicennia apiculata) and kapok trees.Several national parks provide protection of their habitat, including Rawa Aopa Watumohai National Park on Sulawesi, Komodo National Park on Komodo Island, the national parks of Manupeu Tanah Daru and Laiwangi Wanggameti on Sumba, and the Nino Konis Santana National Park in East Timor (Timor-Leste).
+
+
+== Introduced population ==
+An introduced population of these birds is found in Hong Kong. They are a common sight across the densely populated area on both sides of the harbour, easily spotted in the woods and public parks in the north and west of Hong Kong Island. The large group has apparently developed from a number of caged birds that have been released into the Hong Kong area over many years. An often repeated story is that Hong Kong Governor Sir Mark Aitchison Young released the Government House's entire bird collection – including a large number of yellow-crested cockatoos – hours before surrendering Hong Kong to Japanese troops in December 1941.  Historians and conservation biologists in Hong Kong have found no evidence to corroborate this story, and believe that Hong Kong's yellow-crested cockatoo population is made up of escaped pets. The earliest record of an escaped pet yellow-crested cockatoo comes from 1959.

+The long-billed corella or slender-billed corella (Cacatua tenuirostris) is a cockatoo native to Australia, which is similar in appearance to the little corella. This species is mostly white, with a reddish-pink face and forehead, and has a long, pale beak, which is used to dig for roots and seeds. It has reddish-pink feathers on the breast and belly.
+
+
+== Taxonomy ==
+The long-billed corella does not have any recognized subspecies. The first formal written description was by German naturalist Heinrich Kuhl in 1820. It is one of several related species of cockatoos called corellas and classified in the subgenus Licmetis within the genus Cacatua, members of which are known as "white cockatoos".
+
+
+== Description ==
+The adult long-billed corella measures from 38 to 41 cm in length, has a wingspan around 80–90 cm, and averages 567 g in weight. It has a long, bone-coloured beak, and a rim of featherless, bluish skin around the eyes. The plumage is predominantly white with reddish feathers around the eyes and lores. The underside of the wings and tail feathers are tinged with yellow.
+
+
+== Distribution and habitat ==
+The long-billed corella can be found in the wild in Victoria and southeastern New South Wales. It has extended its range since the 1970s into Melbourne, Victoria and can now be found in Tasmania, South Australia and southeast Queensland. A feral population resides in Perth, Western Australia as of the mid-1980s, which has conservation implications as this species may hybridize with the endangered western corella.  
+The long-billed corella is found in grassy woodlands and grasslands, including pasture, fields of agricultural crop, and urban parks.
+
+
+== Ecology and behaviour ==
+
+
+=== Call ===
+The call of the long-billed corella is a quick, quavering, falsetto currup!, wulluk-wulluk, or cadillac-cadillac combined with harsh screeches.
+
+
+=== Breeding ===
+Breeding generally takes place in Austral winter to spring (from July to November). Long-billed corellas form monogamous pairs and both sexes share the task of building the nest, incubating the eggs, and caring for the young. Nests are made in decayed debris, the hollows of large old eucalypts, and occasionally in the cavities of loose gravely cliffs. 2–3 dull white, oval eggs are laid on a lining of decayed wood. The incubation period is around 24 days and chicks spend about 56 days in the nest.
+
+
+=== Feeding ===
+The long-billed corella typically digs for roots, seeds, corms, and bulbs, especially from the weed onion grass. Native plants eaten include murnong Microseris lanceolata, but a substantial portion of the bird's diet now includes introduced plants.
+
+
+== Relationship with humans ==
+
+
+=== As pets ===
+
+Long-billed corellas are now popular as pets in many parts of Australia, although they were formerly uncommon, and their captive population has stabilised in the last decade. This may be due to their ability to mimic words and whole sentences to near perfection. The long-billed corella has been labeled the best "talker" of the Australian cockatoos, and possibly of all native Psittacines.
+
+
+=== As pests ===
+Long-billed corellas are viewed as agricultural pests, particularly in western Victoria and Western Australia. They can create significant crop damage and are also well known for tearing up pieces of asphalt along roadsides and even damaging power lines. Permits are regularly issued in Western Australia and sometimes issued in Victoria for the culling of this species. Within NSW, the corellas are the most common pest among sporting fields and golf courses, as they can dig holes in the ground up to 3 in across and 6 in deep.In July 2019, in a scene that was said to resemble a "horror movie", about 60 corellas in Adelaide, South Australia, died in a suspected case of poisoning, after "falling from the sky", bleeding from their mouths, and wailing. At least 57 of the birds were long-billed corellas, and a few of them were short-billed corellas. It was hoped that whoever poisoned them would get traced after doing a report on toxicology, which could nevertheless take several weeks to complete, because in Australia, people were required to register if they purchase poisons, according to Sarah King, founder of Casper's Bird Rescue, who witnessed the deaths, and also said that the type of poison was a slow one that takes several weeks to work. Additionally, the local Alexandrina council had beforehand called for short-billed corellas to be culled for damaging crops and chewing on streetlights, damaging built infrastructure such as buildings and sporting equipment, and displacing other native species of birds and bees, possums, and other organisms.

+The Goeldi's marmoset or Goeldi's monkey (Callimico goeldii) is a small, South American New World monkey that lives in the upper Amazon basin region of Bolivia, Brazil, Colombia, and Peru. It is the only species classified in the genus Callimico, and the monkeys are sometimes referred to as "callimicos". The species takes its name from its discoverer, Swiss-Brazilian naturalist Emil August Goeldi.Goeldi's marmosets are blackish or blackish-brown in color and the hair on their head and tail sometimes has red, white, or silverly brown highlights. Their bodies are about 8–9 inches (20–23 cm) long, and their tails are about 10–12 inches (25–30 cm) long. They weigh about 0.4835 Kg in captivity and 0.500 Kg in the wild. Their digits have claw like nails except for the hallux, which serve for clinging, scansorial travel, and to extract food from trees.
+
+
+== Taxonomy and Evolution ==
+Goeldi's marmoset was first described in 1904, making Callimico one of the more recent monkey genera to be described. In older classification schemes it was sometimes placed in its own family Callimiconidae and sometimes, along with the marmosets and tamarins, in the subfamily Callitrichinae in the family Cebidae. More recently, Callitrichinae has been (re-)elevated to family status as Callitrichidae.Molecular phylogenetics shows that C. goeldii evolved from an ancestral callitrichine and shares this origin with marmosets making them sister taxa. One evolutionary argument to account for their differences, states that C. goeldii conserves primitive traits such as single births and a third molar lost in many marmosets. Alternatively, another evolutionary argument indicates that Callimicos came from a two-molar marmoset and reintroduced the remote traits, which in either case selectively give them the ability to access to different resources and occupy different niches. Similarities in delayed embryonic development and secondary limb-bone ossification between C. goeldii and marmosets are evidence of their close evolutionary relationship.
+
+
+== Reproduction ==
+Females reach sexual maturity at 8.5 months, males at 16.5 months. The gestation period lasts from 144 to 159 days. Callimicos studied in captivity in North America and Europe for near 40 years have shown to produce on average 3.5 offspring during their lifetime. However, 30% of the females and 45% of the males observed in these settings never reproduced.Unlike other New World monkeys, they have the capacity to give birth twice a year. Biannual births occur regularly in captivity and less consistently in the wild and are attributed to postpartum estrus that allows the female to be ready to reproduce soon after parturition. The availability of fungus -an important food source for C. goeldii- throughout the year also contributes to these multiple births.The mother carries a single baby monkey per pregnancy, whereas most other species in the family Callitrichidae usually give birth to twins. These singleton births provide the offspring with longer maternal care and weaning delay that results in faster growth rates and in turn earlier sexual maturity than the other marmosets.
+
+
+== Infant Care ==
+For the first 2–3 weeks the mother acts as the primary caregiver after which the father and the helpers, who are often the siblings, share many of the responsibilities. However, mothers in the wild have been observed giving their babies to other members of the troop as early as 10 days after parturition, which is late for other marmosets.At birth, Callimicos offspring weigh 10% the weight of their mother’s whereas the twinning marmosets weight double that amount, which explains the delay in allocare in C. goeldii since it is not as crucial as it is for its counterparts. Cooperative care in callitrichines is therefore necessary to help mothers recover from gestation, parturition, and lactation as well as to share the energetic cost of carrying the infant among the helpers and the father.Caregivers must also provide food to the infants when they turn 4 weeks of age. The task of food provisioning includes tolerance to food robbing since infants are at a stage of learning how to forage by themselves. Also at week 4, mothers stop nursing in the wild, but that behaviour is believed to be influenced by the presence of the observers and therefore, it is suspected that nursing resumes when humans are not present. Whereas C. goeldii in captivity, nursing extends until the infant is 8-15 weeks old. Thus, the offspring will be weaned when it becomes about 63 days of age.  There is no difference between male and female helpers on the amount of involvement on infant care. Even juvenile C. goeldii participate as active caregivers.Infants are carried entirely during the first month and 63% of the time on the next month. They do not leave their guardian side until they become 2.5 months of age and around 3 months old, they are rarely carried, but locomotive independence comes more forcibly than voluntarily. Females outnumber males by 2 to 1. The life expectancy in captivity is about 10 years.
+
+
+== Development ==
+From birth to about 18 months old, callimicos grow faster than other marmosets in part because the energy they would otherwise invest on thermal regulation and activity costs if they were not carried by their mothers is instead directed to growth. Likewise, a longer lactation period is also responsible for a faster development. Growth rate and weight gain is similar in both male and female infants and juveniles.
+
+
+== Distribution and Habitat ==
+Callimicos’ geographic distribution extends from the Colombian Amazon in the Rio Caquetá to the Peruvian Amazon down to the western Brazilian Amazon and into the Pando department of northwestern Bolivia. Its presence on the Ecuadorian Amazon has yet to be confirmed. The distribution of this species is patchy, and its density seems to be dependent on its polyspecific associations with tamarins.Sightings of callimicos have been made at the base of the Cordillera Oriental of the Andes in Colombia in the Department of Putumayo along the Putumayo and Caquetá rivers.In Peru, to the north of the country, they occur in the Pucacuro National Reserve close to the Tigre River, where they are known as Chichi by residents in the area. To the south, they are found at the Centro de Investigación y Capacitación Río Los Amigos (CICRA), the Manu National Park, and the Concesión de Conservación Rodal Semillero Tahuamanu (CCRST), as well as at areas adjacent to the two later ones. Callimicos were also spotted near the Yurua River and Sierra del Divisor in groups of 3 to 12 individuals each.Some of the records were obtained by trapping during the 70s and 80, and on one of those occasions, the group was brought for breeding at the Centro de Conservación y Reprodución de Primates in Iquitos. Provisioning in stationary sites and playbacks that mimicked their vocalizations and that of tamarines with whom they associate were also employed to attract them.In Brazil, they occur in the south-west Amazon of the state of Acre in Brazil, over the Serra do Divisor south near Juruá river, into the Gregório river at the state of Amazonas, to the Laco river, further south to the upper Purús and in the Madeira basin near the Abunã river in the state of Rondônia. High densities of this species have been recorded in the Pando department in Bolivia.Goeldi's marmosets prefer to forage in dense scrubby undergrowth; perhaps because of this, they are rare, with groups living in separate patches of suitable habitat, separated by miles of unsuitable flora. In the wet season, their diet includes fruit, insects, spiders, lizards, frogs, and snakes. In the dry season, they feed on fungi, the only tropical primates known to depend on this source of food. They live in small social groups (approximately six individuals) that stay within a few feet of one another most of the time, staying in contact via high-pitched calls. They are also known to form polyspecific groups with tamarins such as the white-lipped tamarin and brown-mantled tamarin.  This is perhaps because Goeldi's marmosets are not known to have the X-linked polymorphism which enables some individuals of other New World monkey species to see in full tri-chromatic vision.

+The black-tufted marmoset (Callithrix penicillata), also known as Mico-estrela in Portuguese, is a species of New World monkey that lives primarily in the Neo-tropical gallery forests of the Brazilian Central Plateau. It ranges from Bahia to Paraná, and as far inland as Goiás, between 14 and 25 degrees south of the equator, and can commonly be seen in the City of Rio de Janeiro where it was introduced. This marmoset typically resides in rainforests, living an arboreal life high in the trees, but below the canopy. They are only rarely spotted near the ground.
+
+
+== Physical description ==
+The black-tufted marmoset is characterized by black tufts of hair around their ears. It typically has some sparse white hairs on its face. It usually has a brown or black head and its limbs and upper body are gray, as well as its abdomen, while its rump and underside are usually black. Its tail is ringed with black and white and is not prehensile, but is used for balance. It does not have an opposable thumb and its nails tend to have a claw-like appearance. The black-tufted marmoset reaches a size of 7.48 to 8.7 inches (19.0 to 22.1 centimetres) and weighs up to 12.35 oz (350 g).
+
+
+== Behavior ==
+
+Diurnal and arboreal, the black-tufted marmoset has a lifestyle very similar to other marmosets. It typically lives in family groups of 2 to 14. The groups usually consist of a reproductive couple and their offspring. Twins are very common among this species and the males, as well as juvenile offspring, often assist the female in the raising of the young.
+Though the black-tufted marmoset lives in small family groups, it is believed that they share their food source, sap trees, with other marmoset groups. Scent marking does occur within these groups, but it is believed that the marking is to deter other species rather than other black-tufted marmoset groups, because other groups typically ignore these markings. They also appear to be migratory, often moving in relation to the wet or dry seasons, however, the extent of their migration is unknown.
+Though communication between black-tufted marmosets has not been studied thoroughly, it is believed that it communicates through vocalizations. It has known predator-specific cries and appears to vocalize frequently outside of predator cries.
+
+
+== Food and predation ==
+ The black-tufted marmoset diet consists primarily of tree sap which it gets by nibbling the bark with its long lower incisors. In periods of drought, it will also include fruit and insects in its diet. In periods of serious drought it has also been known to eat small arthropods, molluscs, bird eggs, baby birds and small vertebrates.
+Large birds of prey are the greatest threat to the black-tufted marmoset, however, snakes and wild cats also pose a danger to them. Predator-specific vocalizations and visual scanning are its only anti-predation techniques.
+
+
+== Reproduction ==
+The black-tufted marmoset is monogamous and lives in family groups. It reproduces twice a year, producing 1 to 4 offspring, though most often just twins. Its gestation period is 150 days and offspring are weaned after 8 weeks. There is considerable parental investment by this species, with both parents, as well as older juveniles, helping to raise the young. The offspring are extremely dependent on their parents and though they are sexually mature at 18 months, they typically do not mate until much later, staying with their family group until they do.
+
+
+== Ecosystem roles and conservation status ==
+The black-tufted marmoset is a mutualist with many species of fruit trees because it distributes the seeds from the fruit it consumes throughout the forests. However, it is a parasite on other species of trees because it creates sores in trees in order to extract sap, while offering no apparent benefit to the trees. Though this marmoset is not a main food source to any specific species, it is a food source to a number of different species, specifically large birds of prey, wild cats, and snakes.
+The black-tufted marmoset is listed as having no special status on the IUCN Red List or the United States Endangered Species Act List. It is listed in Appendix II of CITES and is not currently considered an endangered or threatened species. In Rio de Janeiro State, where it was introduced alongside the common marmoset, it is considered as an invasive species posing a danger to the survival of the endangered golden lion tamarin through competition. Management of the species in its invaded habitat has included proposals for sterilization of reproductive-age individuals, relocation, and public awareness campaign for prevention of further releases.

+The Nicobar pigeon (Caloenas nicobarica, Car: ma-kūö-kö) is a bird found on small islands and in coastal regions from the Andaman and Nicobar Islands, India, east through the Malay Archipelago, to the Solomons and Palau. It is the only living member of the genus Caloenas alongside the extinct spotted green pigeon, and is the closest living relative of the extinct dodo and Rodrigues solitaire.
+
+
+== Taxonomy ==
+In 1738, the English naturalist Eleazar Albin included a description and two illustrations of the Nicobar pigeon in his A Natural History of Birds. When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he placed the Nicobar pigeon with all the other pigeons in the genus Columba. Linnaeus included a brief description, coined the binomial name Columba nicobarica and cited Albin's work. The species is now placed in the genus Caloenas erected by English zoologist George Robert Gray in 1840 with the Nicobar pigeon as the type species.Two subspecies are recognised:
+C. n. nicobarica (Linnaeus, 1758) – Andaman and Nicobar Islands, Malay Archipelago to New Guinea, Philippines and Solomon Islands
+C. n. pelewensis Finsch, 1875 – Palau IslandBased on cladistic analysis of mtDNA cytochrome b and 12S rRNA sequences, the Nicobar pigeon is sometimes called the closest living relative of the extinct didines (Raphinae), which include the famous dodo (Raphus cucullatus). However, the study's results showed this as one weak possibility from a limited sample of taxa.  In any case, nDNA β-fibrinogen intron 7 sequence data agrees with the idea of the Raphinae as a subfamily of pigeons (and not an independent family, as was previously believed due to their bizarre apomorphies) that was part of a diverse Indopacific radiation, to which the Nicobar pigeon also belongs.The following cladogram, from Shapiro and colleagues (2002), shows the Nicobar pigeon's closest relationships within Columbidae, a clade consisting of generally ground-dwelling island endemics.
+
+A similar cladogram was published in 2007, differing only in the inverted placement of Goura and Didunculus, as well as in the inclusion of the pheasant pigeon and the thick-billed ground pigeon at the base of the clade.C. nicobarica is a quite singular columbiform (though less autapomorphic than the flightless Raphinae), as are for example the tooth-billed pigeon (Didunculus strigirostris) and the crowned pigeons (Goura), which are typically considered distinct subfamilies. Hence, the Nicobar pigeon may well constitute another now-monotypic subfamily. And while any of the semi-terrestrial pigeons of Southeast Asia and the Wallacea cannot be excluded as possible closest living relative of the Raphinae, the Nicobar pigeon makes a more plausible candidate than for example the group of imperial-pigeons and fruit-doves, which seems to be part of the same radiation.Whether it is possible to clarify such deep-time phylogenies without a comprehensive study of all major lineages of living Columbidae remains to be seen. The primitive molecular clock used to infer the date the ancestors of the Nicobar pigeon and the didines diverged has since turned out to be both unreliable and miscalibrated. But what little evidence is available still suggests that the Nicobar pigeon is distinct from all other living lifeforms since the Paleogene – most likely some time between 56-34 million years ago during the Eocene, which makes up the bulk of the Paleogene period.From subfossil bones found on New Caledonia and Tonga, an extinct species of Caloenas, the Kanaka pigeon (C. canacorum) was described. It was about one-quarter larger than the Nicobar pigeon. Considering that it must have been a good source of food, it was most likely hunted to extinction by the first human settlers of its home islands. It probably was extinct by 500 BC. The Spotted green pigeon (C. maculata) is a more recently extinct species from an unknown Pacific locality; it probably disappeared in the 19th century and most likely succumbed to introduced European rats. It is placed in Caloenas as the least awkward possibility; its true affinities are presently indeterminate and it is perhaps more likely to represent a distinct genus of the Indopacific radiation of Columbidae.
+
+
+== Description ==
+
+It is a large pigeon, measuring 40 cm (16 in) in length. The head is grey, like the upper neck plumage, which turns into green and copper hackles. The tail is very short and pure white. The rest of its plumage is metallic green. The cere of the dark bill forms a small blackish knob; the strong legs and feet are dull red. The irises are dark.Females are slightly smaller than males; they have a smaller bill knob, shorter hackles and browner underparts. Immature birds have a black tail and lack almost all iridescence. There is hardly any variation across the birds' wide range. Even the Palau subspecies C. n. pelewensis has merely shorter neck hackles, but is otherwise almost identical.It is a very vocal species, giving a low-pitched repetitive call.
+
+
+== Distribution and habitat ==
+
+On the Nicobar Islands (which are referred to in its common and scientific names), the most significant colony of Nicobar pigeons in modern times was found on Batti Malv, a remote wildlife sanctuary between Car Nicobar and Teressa. The 2004 Indian Ocean tsunami caused massive damage on the Nicobar Islands, and to what extent Batti Malv was affected is still not clear. But while everything on some islets in the Great Nicobar Biosphere Reserve was destroyed, Batti Malv lighthouse – a skeletal tower a dozen metres high, standing a few metres ASL at the highest point of the low-lying island – was little-damaged and put back in operation by the survey ship INS Sandhayak less than one month after the disaster. An April 2007 survey by the Indian Coast Guard vessel ICGS Vikram found the lighthouse tower "totally covered" in vines, indicating rampant regeneration of vegetation – but perhaps also that damage to the island's forest was severe, as a cover of creeping plants is typical of early succession stages, while a photo of the lighthouse taken before the tsunami shows rather mature forest.
+
+
+=== Found in Australia ===
+A Nicobar pigeon was found by the Bardi Jawi Indigenous rangers on the Dampier Peninsula in the western Kimberley, Australia in May 2017. As part of biosecurity measures, it was reported to quarantine services and was removed by Australian Department of Agriculture officials.
+
+
+== Behaviour and ecology ==
+The Nicobar pigeon's breeding range encompasses the Andaman and Nicobar Islands of India, the Mergui Archipelago of Myanmar, offshore islands of south-western Thailand, Peninsular Malaysia, southern Cambodia and Vietnam, and many of the small islands between Sumatra, the Philippines and the Solomon Islands. On Palau, the only distinct subspecies C. n. pelewensis is found.
+
+The Nicobar pigeon roams in flocks from island to island, usually sleeping on offshore islets where no predators occur and spends the day in areas with better food availability, not shying away from areas inhabited by humans. Its food consists of seeds, fruit and buds, and it is attracted to areas where grain is available. A gizzard stone helps to grind up hard food items. Its flight is quick, with regular beats and an occasional sharp flick of the wings, as is characteristic of pigeons in general. Unlike other pigeons, groups tend to fly in columns or single file, not in a loose flock. The white tail is prominent in flight when seen from behind and may serve as a sort of "taillight", keeping flocks together when crossing the sea at dawn or dusk. The young birds' lack of a white tail is a signal of their immaturity clearly visible to conspecifics – to an adult Nicobar pigeon, it is obvious at a glance which flockmembers are neither potential mates, nor potential competitors for mates, nor old enough to safely guide a flock from one island to another.This species nests in dense forest on offshore islets, often in large colonies. It builds a loose stick nest in a tree. It lays one elliptical faintly blue-tinged white egg.In 2017, several individual Caloenas nicobarica were sighted in the Kimberley region of Western Australia with a juvenile captured at Ardyaloon (One Arm Point), near Broome - the first time the bird has been sighted on the Australian mainland.
+
+
+== Conservation ==
+
+Nicobar pigeons are hunted in considerable numbers for food, and also for their gizzard stone which is used in jewellery. The species is also trapped for the local pet market, but as it is on CITES Appendix I, commercial international trade is prohibited. Internationally, captive breeding is able to supply the birds demanded by zoos, where this attractive and unusual bird is often seen. Direct exploitation of the species, even including the illegal trade, might be sustainable on its own; however, its available nesting habitat is decreasing. The offshore islets which it requires are often logged for plantations, destroyed by construction activity, or polluted by nearby industry or harbours. Also, increased travel introduces predators to more and more of the breeding sites, and colonies of the Nicobar pigeon may be driven to desert such locations or be destroyed outright. Though the bird is widely distributed and in some locations very common --even on small Palau it is still reasonably plentiful, with an estimated 1,000 adult birds remaining—its long-term future is increasingly jeopardized. For these reasons, the IUCN considers C. nicobarica a near threatened species.

+The Bactrian camel (Camelus bactrianus), also known as the Mongolian camel or domestic Bactrian camel, is a large even-toed ungulate native to the steppes of Central Asia. It has two humps on its back, in contrast to the single-humped dromedary. Its population of 2 million exists mainly in the domesticated form. Their name comes from the ancient historical region of Bactria.Domesticated Bactrian camels have served as pack animals in inner Asia since ancient times. With its tolerance for cold, drought, and high altitudes, it enabled the travel of caravans on the Silk Road. Bactrian camels, whether domesticated or feral, are a separate species from the wild Bactrian camel, which is the only truly wild (as opposed to feral) species of camelid in the Old World.
+
+
+== Taxonomy ==
+The Bactrian camel shares the genus Camelus with the dromedary (C. dromedarius) and the wild Bactrian camel (C. ferus). The Bactrian camel belongs to the family Camelidae. The ancient Greek philosopher Aristotle was the first European to describe the camels: In his 4th century BCE History of Animals he identified the one-humped Arabian camel and the two-humped Bactrian camel. The Bactrian camel was given its current binomial name Camelus bactrianus by Swedish zoologist Carl Linnaeus in his 1758 publication Systema Naturae.In 2007, Peng Cui (of the Chinese Academy of Sciences) and colleagues carried out a phylogenetic study of the evolutionary relationships between the two tribes of Camelidae: Camelini – consisting of the three Camelus species (the study considered the wild Bactrian camel as a subspecies of the Bactrian camel) – and Lamini – consisting of the alpaca (Vicugna pacos), the guanaco (Lama guanicoe), the llama (L. glama) and the vicuña (V. vicugna). The study revealed that the two tribes had diverged 25 million years ago (early Miocene), notably earlier than what had been previously estimated from North American fossils. Speciation began first in Lamini as the alpaca came into existence 10 million years ago. Nearly 2 million years later, the Bactrian camel and the dromedary emerged as two independent species. However, the fossil record suggests a far more recent divergence between the Bactrian camel and the dromedary because despite a moderately rich fossil record of camelids, no fossil that fits within this divergence is older than middle Pleistocene (about 0.8 Ma).The Bactrian camel and the dromedary often interbreed to produce fertile offspring. Where the ranges of the two species overlap, such as in northern Punjab, Iran and Afghanistan, the phenotypic differences between them tend to decrease as a result of extensive crossbreeding between them. The fertility of their hybrid has given rise to speculation that the Bactrian camel and the dromedary should be merged into a single species with two varieties. However, a 1994 analysis of the mitochondrial cytochrome b gene revealed that the species display 10.3% divergence in their sequences.
+
+
+=== Differences from wild Bactrian camels ===
+The wild Bactrian camel (Camelus ferus) was first described by Nikolay Przhevalsky in the late 19th century and has now been established as a distinct species from the Bactrian camel (Camelus bactrianus).
+Zoological opinion nowadays tends to favour the idea that C. bactrianus and C. dromedarius are descendants of two different subspecies of C. ferus (Peters and von den Driesch 1997: p. 652) and there is no evidence to suggest that the original range of C. ferus included those parts of Central Asia and Iran where some of the earliest Bactrian remains have been found. In particular, a population of wild Bactrian camel has been discovered to live within a part of the Gashun Gobi region of the Gobi Desert. This population is distinct from domesticated herds both in genetic makeup and in behavior.As many as three regions in the genetic makeup are distinctly different from Bactrian camels, with up to a 3% difference in the base genetic code. However, with so few wild camels, what the natural genetic diversity within a population would have been is not clear.Another difference is the ability of these wild camels to drink saltwater slush, although whether the camel can extract useful water from it is not yet certain. Domesticated camels are unable to drink such salty water.
+
+
+== Description ==
+
+The Bactrian camel is the largest mammal in its native range and is the largest living camel while being shorter at the shoulder than the dromedary. Shoulder height is from 160 to 180 cm (5.2 to 5.9 ft) with the overall height ranging from 230 to 250 cm (7.5 to 8.2 ft), head-and-body length is 225–350 cm (7.38–11.48 ft), and the tail length is 35–55 cm (14–22 in). At the top of the humps, the average height is 213 cm (6.99 ft).
+
+Body mass can range from 300 to 1,000 kg (660 to 2,200 lb), with males weighing around 600 kg, and females around 480 kg. Its long, wooly coat varies in colour from dark brown to sandy beige. A mane and beard of long hair occurs on the neck and throat, with hairs measuring up to 25 cm (9.8 in) long.
+The shaggy winter coat is shed extremely rapidly, with huge sections peeling off at once, appearing as if sloppily shorn. The two humps on the back are composed of fat (not water as is sometimes thought). The face is typical of a camelid, being long and somewhat triangular, with a split upper lip. The long eyelashes, along with the sealable nostrils, help to keep out dust in the frequent sandstorms which occur in their natural range. The two broad toes on each foot have undivided soles and are able to spread widely as an adaptation to walking on sand. The feet are very tough, as befits an animal of extreme environments.
+
+
+== Natural habitat ==
+These camels are migratory, and their habitat ranges from rocky mountain massifs to flat arid desert, stony plains, and sand dunes. Conditions are extremely harsh – vegetation is sparse, water sources are limited and temperatures are extreme. The coat of the Bactrian camel can withstand cold as low as −30 °C (−22 °F) in winter to 50 °C (122 °F) in summer. The camels' distribution is linked to the availability of water, with large groups congregating near rivers after rain or at the foot of the mountains, where water can be obtained from springs in the summer months, and in the form of snow during the winter.
+
+
+== Life history ==
+
+Bactrian camels are exceptionally adept at withstanding wide variations in temperature, ranging from freezing cold to blistering heat. They have a remarkable ability to go without water for months at a time, but when water is available they may drink up to 57 liters at once. When well fed, the humps are plump and erect, but as resources decline, the humps shrink and lean to the side. When moving faster than a walking speed, they pace, by stepping forwards with both legs on the same side (as opposed to trotting, using alternate diagonals as done by most other quadrupeds). Speeds of up to 65 kilometres per hour (40 mph) have been recorded, but they rarely move this fast. Bactrian camels are also said to be good swimmers. The sense of sight is well developed and the sense of smell is extremely good. The lifespan of Bactrian camels is estimated at up to 50 years, more often 20 to 40 in captivity.
+
+
+=== Diet ===
+
+Bactrian camels are diurnal, sleeping in the open at night and foraging for food during the day. They are primarily herbivorous. With tough mouths that can withstand sharp objects such as thorns, they are able to eat plants that are dry, prickly, salty or bitter, and can ingest virtually any kind of vegetation. When other nutrient sources are not available, these camels may feed on carcasses, gnawing on bones, skin, or various different kinds of flesh. In more extreme conditions, they may eat any material they find, which has included rope, sandals, and even tents. Their ability to feed on a wide range of foods allows them to live in areas with sparse vegetation. The first time food is swallowed, it is not fully chewed. The partly masticated food (called cud) goes into the stomach and later is brought back up for further chewing.
+Bactrian camels belong to a fairly small group of animals that regularly eat snow to provide their water needs. Animals living above the snowline may have to do this, as snow and ice can be the only forms of water during winter, and by doing so, their range is greatly enlarged. The latent heat of snow and ice is big compared with the heat capacity of water, forcing animals to eat only small amounts at a time.
+
+
+=== Reproduction ===
+
+Bactrian camels are induced ovulators – they ovulate after insemination (insertion of semen into the vagina); the seminal plasma, not the spermatozoa, induces ovulation. Ovulation occurs in 87% of females after insemination: 66% ovulate within 36 hours and the rest by 48 hours (the same as natural mating). The least amount of semen required to elicit ovulation is about 1.0 ml.Males during mating time are often quite violent and may bite, spit, or attempt to sit on other male camels. The age of sexual maturity varies, but is usually reached at 3–5 years. Gestation lasts around 13 months. One or occasionally two calves are produced, and the female can give birth to a new calf every other year. Young Bactrian camels are precocial, being able to stand and run shortly after birth, and are fairly large at an average birth weight of 36 kg (79 lb). They are nursed for about 1.5 years. The young calf stays with its mother for three to five years, until it reaches sexual maturity, and often helps raise subsequent generations for those years. Wild camels sometimes breed with domesticated or feral camels.
+
+
+== Genome ==
+The Bactrian Camels Genome Sequencing and Analysis Consortium provides a C. bactrianus ferus genome using next generation sequencing.
+
+
+== Relationship to humans ==
+
+The Bactrian camel was domesticated circa ~4,500 BCE. The dromedary is believed to have been domesticated between 4000 BCE and 2000 BCE in Arabia. As pack animals, these ungulates are virtually unsurpassed, able to carry 170–250 kg (370–550 lb) at a rate of 47 kilometres (29 mi) per day, or 4 kilometres per hour (2.5 mph) over a period of four days. The species was a mainstay of transportation on the Silk Road. Furthermore, Bactrian camels are frequently ridden, especially in desertified areas. In ancient Sindh, for example, Bactrian camels of two humps were initially used by the rich for riding. The camel was later brought to other areas such as Balochistan and Iran for the same purpose.
+Bactrian camels have been the focus of artwork throughout history. For example, western foreigners from the Tarim Basin and elsewhere were depicted in numerous ceramic figurines of the Chinese Tang dynasty (618–907).
+
+
+=== United States imports ===
+Bactrian camels were imported to the U.S. several times in the mid- to late 1800s, both by the U.S. military and by merchants and miners, looking for pack animals sturdier and hardier than horses and mules. Although the camels met these needs, the United States Camel Corps was never considered much of a success. Having brought two shipments of fewer than 100 camels to the U.S., plans were made to import another 1,000, but the US Civil War interrupted this. Most surviving camels of these endeavors, both military and private, were merely turned loose to survive in the wild. As a result, small feral herds of Bactrian camels existed during the late 19th century in the southwest deserts of the United States.
+
+
+=== Documentaries ===
+The Story of the Weeping Camel is a 2003 Mongolian documentary/story about a family of nomadic shepherds trying to get a white calf accepted by his mother, which rejected him after a difficult birth.
+
+
+=== Military use ===
+The Indian Army uses these camels to patrol in Ladakh. It was concluded that after carrying out trials and doing a comparative study with a single-humped camel brought from Rajasthan that the double-humped camel is better suited for the task at hand. Colonel Manoj Batra, a veterinary officer of the Indian Army, stated that the double-humped camel "are best suited for these conditions. They can carry loads of 170 kilograms (370 lb) at more than 17,000 feet (5,200 m) which is much more than the ponies that are being used as of now. They can survive without water for at least 72 hours."

+The Iberian wolf (Canis lupus signatus, or Canis lupus lupus, Spanish and Portuguese : Lobo ibérico), is a subspecies of grey wolf. It inhabits the northwest of the Iberian Peninsula, which includes northwestern Spain and northern Portugal. It is home to 2,200-2,700 wolves which have been isolated from mixing with other wolf populations for over a century. They form the largest wolf population in Western Europe.Due to population controls and damage to livestock, Iberian wolves were, as of September 2021, the only Western European subspecies of wolf whose hunting remained legal, yet only in Spain. Nonetheless, very few hunting permits were given every year, strictly north of the Douro river. Along with the difficulty of their hunt by virtue of their vigilant nature and the rarity of their sightings, they were strongly desired by many European hunters as a big-game trophy.
+
+
+== Taxonomy ==
+The Iberian wolf Canis lupus signatus Cabrera 1907 is classified as Canis lupus lupus by Mammal Species of the World. Some authors claim that the south-eastern Spanish wolf, last sighted in Murcia in the 1930s, was a different subspecies called Canis lupus deitanus. It was even smaller and more reddish in color, without dark spots. Both subspecies were nominated by the Spanish-born zoologist Ángel Cabrera in 1907.
+The Iberian wolf's skull morphometrics, mtDNA, and microsatellites differ from other European wolves. In 2016, a study of mitochondrial DNA sequences of both modern and ancient wolves indicated that in Europe, the two most genetically distinct haplotypes form the Italian wolf, and separately, the Iberian wolf.
+The National Center for Biotechnology Information/Genbank lists the Iberian wolf under Canis lupus signatus.In 2020, a genomic study of Eurasian wolves found that the populations of the Dinaric Alps-Balkan Mountains region, the Iberian peninsula, and Italy diverged from each other 10,500 years ago followed by negligible gene flow between them. Their long-term isolation may explain the morphological and genetic differences between them.
+
+
+== Description ==
+
+Cabrera identified two types of wolves living in Spain. In comparison, C. l. lupus had a pale, undefined stroke on the cheek that contrasts with the white on the throat; C. l. signatus had a white stroke on the cheek that joins the white throat and with a reddish snout; and C. l. deitanus was much smaller and with more colouring than the wolves to the north. C. l. signatus is described by Cabrera as being 140–180 cm in head and body length, and 70–80 cm height at the shoulders.The Iberian wolf differs from the more common Eurasian wolf with its slighter frame, white marks on the upper lips, the dark marks on the tail, and a pair of dark marks in its front legs that give it its subspecies name, signatus ("marked"). The subspecies differentiation may have developed at the end of the Pleistocene Ice Ages due to the isolation of the Iberian Peninsula when glacier barriers grew in the Pyrenees and eventually reached the Gulf of Biscay in the west and the Mediterranean in the east.
+Height is 70–90 cm and body length 110–140 cm. Females weigh 25–35 kg while Males weigh 35–55 kg.
+
+
+== Diet ==
+The Iberian wolf lives in small packs. It is considered to be beneficial because it keeps the population of wild boars stable, thus allowing some respite to the endangered capercaillie populations which suffer greatly from boar predation. It also eats rabbits, roe deer, red deer, ibexes and even small carnivores and fish.
+
+
+== Distribution and conservation ==
+Wolf populations strongly declined across Europe during the 18th and 19th centuries largely due to human persecution, and by the end of the Second World War they had been eradicated from all of Central Europe and almost all of Northern Europe. Their population decline continued until the 1960s, with isolated populations surviving in Italy, Spain, Portugal, Greece, and Finland. Wolf populations have commenced recovering naturally since then.
+
+The Iberian wolf consists of over 2,000 individuals in over 350 packs distributed across 140,000 km2. 
+Their densities in some regions are among the highest in Europe, with up to 7 wolves/100 km2. In 2018, a study identified that this wolf could be categorised into 11 genetic groups. Four groups were identified in the Portuguese regions of Alto Minho, Alto Trás-os-Montes, and one group located south of the Douro river. Seven groups were identified in the Spanish regions of western Galicia, eastern Galicia, western Asturias, central Asturias, eastern Asturias, south-eastern Asturias, and Castilla y León.Until the 1930s, Iberian wolves were relatively spread throughout Portugal, but destruction of habitat, loss of wild ungulates and the persecution by humans made it lose most of its territory (from around 44,100 km2 in 1900–1930, to only 16,300 km2 in 2002–2003) though populations have grown to about 29,000 km2 since.Some Spanish naturalists and conservationists such as Félix Rodríguez de la Fuente called for the end of the hunting and the protection of the animal. Today, the hunting of wolves is banned in Portugal, and in Spain since 2021. The 2003 census estimated the total Iberian population to be 2,000 wolves. Wolves have been reported as returning to Navarre and the Basque Country and to the provinces of Extremadura, Madrid, and Guadalajara. A male wolf was found recently in Catalonia, where the last native wolf was killed in 1929. However, this animal was not a member of the Iberian subspecies, but an Italian wolf (C. l. italicus) migrating from France. As of 2013, an estimated 300 individuals remain in Portugal.In October 2013, Ecologists in Action called for an urgent review of the Iberian wolf census, which may overestimate their numbers. Later that month, wolf association Lobo Marley sent 198,000 signatures calling for the animal's protection to the European Parliament Committee on Petitions. Over a few weeks in September and October 2013, about 30 puppies and young wolves were killed by hunters in Asturias, León, and Cantabria.Although hunting is banned in Portugal, about 45% of wolf deaths are due to human activities, including illegal hunting. Calling the rate unsustainable, 10 organisations signed a statement requesting stronger protection.
+
+
+=== Southern population ===
+
+Sierra Morena is a system of rugged mountain ranges in the south of the Iberian Peninsula where a very small wolf population has lived in isolation for half a century. A breeding pair of wolves was last sighted in 2013, however an extensive survey in 2016 could not find a breeding population. The DNA of a road-killed wolf from 2003 indicated high levels of inbreeding and 30% of the genome being that of dog. It is thought that as the population of these wolves declined, the inability to find a mate led to inbreeding and hybridization with dogs. The wolves in this region may now be extinct.

+The crested caracara (Caracara plancus) is a bird of prey in the family Falconidae. It is found from the southern United States through Central and South America to Tierra del Fuego. It was formerly placed in the genus Polyborus.
+
+
+== Description ==
+The crested caracara has a total length of 50–65 cm (20–26 in) and a wingspan of 120–132 cm (47–52 in). Its weight is 0.9–1.6 kg (2.0–3.5 lb), averaging 1,348 g (2.972 lb) in seven birds from Tierra del Fuego. Individuals from the colder southern part of its range average larger than those from tropical regions (as predicted by Bergmann's rule) and are the largest type of caracara. In fact, they are the second-largest species of falcon in the world by mean body mass, second only to the gyrfalcon. The cap, belly, thighs, most of the wings, and tail tip are dark brownish, the auriculars (feathers surrounding the ear), throat, and nape are whitish-buff, and the chest, neck, mantle, back, upper tail coverts, crissum (the undertail coverts surrounding the cloaca), and basal part of the tail are whitish-buff barred dark brownish. In flight, the outer primaries show a large conspicuous whitish-buff patch ('window'), as in several other species of caracaras. The legs are yellow and the bare facial skin and cere are deep yellow to reddish-orange. Juveniles resemble adults, but are paler, with streaking on the chest, neck, and back, grey legs, and whitish, later pinkish-purple, facial skin and cere.
+
+		
+		
+		
+		
+
+
+== Behavior ==
+A bold, opportunistic raptor, the crested caracara is often seen walking around on the ground looking for food. It mainly feeds on carcasses of dead animals, but steals food from other raptors, raids bird and reptile nests, and takes live prey if the possibility arises (mostly insects or other small prey [such as small mammals, small birds, amphibians, reptiles, fish, crabs, and worms], but at least up to the size of a snowy egret). It may also eat fruit. It is dominant over the black and turkey vulture at carcasses. The crested caracara takes live prey that has been flushed by wildfire, cattle, and farming equipment. The opportunistic nature of this species means that the crested caracara seeks out the phenomena associated with its food, e.g. wildfires and circling vultures. It is typically solitary, but several individuals may gather at a large food source (e.g. dumps). Breeding takes place in the Southern Hemisphere spring/summer in the southern part of its range, but timing is less strict in warmer regions. The nest is a large, open structure, typically placed on the top of a tree or palm, but sometimes on the ground. The typical clutch size is two eggs.
+
+		
+		
+		
+		
+		
+		
+
+
+== Distribution and habitat ==
+The crested caracara occurs from Tierra del Fuego in southernmost South America to the southern United States, Mexico, and Central America. An isolated population occurs on the Falkland Islands. It avoids the Andean highlands and dense humid forest, such as the Amazon rainforest, where it is largely restricted to relatively open sections along major rivers. Otherwise, it occurs in virtually any open or semi-open habitat and is often found near humans.
+Reports have been made of the crested caracara as far north as San Francisco, California. and, in 2012, near Crescent City, California. Some are believed to possibly be living in Nova Scotia, with numerous sightings throughout the 2010s. In July 2016 a northern caracara was reported and photographed by numerous people in the upper peninsula of Michigan, just outside of Munising. In June 2017, a northern caracara was sighted far north in St. George, New Brunswick, Canada. A specimen was photographed in Woodstock, Vermont in March 2020. The species has recently become more common in central and north Texas and is generally common in south Texas and south of the US border. It can also be found (nesting) in the Southern Caribbean (e.g. Aruba, Curaçao and Bonaire), Mexico, and Central America. 
+
+
+=== Florida caracara ===
+Florida is home to a relict population of northern caracaras that dates to the last glacial period, which ended around 12,500 BP. At that time, Florida and the rest of the Gulf Coast were covered in an oak savanna. As temperatures increased, the savanna between Florida and Texas disappeared. Caracaras were able to survive in the prairies of central Florida and the marshes along the St. Johns River. Cabbage palmettos are a preferred nesting site, although they also nest in southern live oaks. Their historical range on the modern-day Florida peninsula included Okeechobee, Osceola, Highlands, Glades, Polk, Indian River, St. Lucie, Hardee, DeSoto, Brevard, Collier, and Martin counties. They are currently most common in DeSoto, Glades, Hendry, Highlands, Okeechobee, and Osceola Counties. It has been seen on the East Coast as far as extreme eastern Seminole County, Florida (Lake Harney), where it is now considered a resident, but listed as threatened. 
+
+
+=== Crested caracara in Mexico ===
+Mexican ornithologist Rafael Martín del Campo proposed that the northern caracara was possibly the sacred "eagle" depicted in several pre-Columbian Aztec codices, as well as the Florentine Codex. This imagery was adopted as a national symbol of Mexico, but it is not the bird depicted on the flag, which is a golden eagle (Aquila chrysaetos), which is the national bird.
+
+
+=== Texan eagle ===
+Balduin Möllhausen, the German artist accompanying the 1853 railroad survey (led by Lt. Amiel Weeks Whipple) from the Canadian River to California along the 35th parallel, recounted observing what he called the "Texan Eagle", which, in his account, he identified as Audubon's Polyborus vulgaris. This sighting occurred in the Sans Bois Mountains in southeastern Oklahoma. Many Texans incorrectly refer to the caracara as the “Mexican eagle”.
+
+
+== Status ==
+Throughout most of its range, its occurrence is common to very common. It is likely to benefit from the widespread deforestation in tropical South America, so is considered to be of least concern by BirdLife International.

+The red-legged seriema  (Cariama cristata), also known as the crested cariama  and crested seriema, is a mostly predatory terrestrial bird in the seriema family (Cariamidae), included in the Gruiformes in the old paraphyletic circumscription but recently placed in a distinct order: Cariamiformes (along with three extinct families).
+The red-legged seriema is widely distributed in South America, occurring in central and eastern Brazil through eastern Bolivia and Paraguay to Uruguay and central Argentina (south to La Pampa).Like the black-legged seriema, farmers often use them as guard animals to protect poultry from predators and sometimes human intruders.
+
+
+== Taxonomy ==
+The red-legged seriema was described in 1766 by the Swedish naturalist Carl Linnaeus in the twelfth edition of his Systema Naturae. He coined the binomial name Palamedea cristata. The red-legged seriema is now the only species placed in the genus Cariama that was introduced by the French zoologist Mathurin Jacques Brisson in 1760. The specific epithet cristata is Latin for "crested", "plumed" or "tufted". The German naturalist Georg Marcgrave used the Latin word Cariama for the red-legged seriema in his Historia naturalis Brasiliae, which was published in 1648.The name is derived from the Portuguese word seriema, which comes from a Tupi word corresponding to çariama, derived from the words çaria (crest) and am (raised).
+
+
+== Description ==
+
+The red-legged seriema is around 75 to 90 centimetres (30 to 35 in) long and weighs about 1.5 to 2.2 kilograms (3.3 to 4.9 lb), with long legs, necks, and tails. The males are slightly larger than females. It has a greyish-brown plumage, finely barred and vermiculated with dark brown and black; pale brown on the head, neck, and breast; white on belly. The long, broad outer tail has a subterminal black band and a white tip. It has a reddish beak and very long, salmon-coloured legs. The eyes are yellow. Soft feathers emerge from the base of the bill to form a distinctive fan-shaped crest.Many other characteristics are shared with the black-legged seriema (Chunga burmeisteri), the only other living member of its family. Some of these traits are discussed in the Cariamidae article.
+
+
+== Distribution and habitat ==
+The red-legged seriema inhabits most of central and eastern Brazil, Paraguay, eastern and southeastern Bolivia, Uruguay, and northeastern Argentina. It is found at elevations up to 6,600 feet (2,000 m).The red-legged seriema prefers grassland habitat to any other. Though it likes to inhabit lush meadows near rivers, it will not readily move into wetlands or crop fields. It frequents semi-open and fairly dry areas such as thorny scrub and semi-arid woodland regions, savannas and ranchlands, and also hilly grasslands near wooded areas. This species is very typical in Caatinga, Cerrado and Chaco.
+
+
+== Behavior and ecology ==
+Seriemas are wary, territorial, and diurnal birds. Generally, the red-legged seriema is sedentary, although there are reports of temperature-related migrations. It is typically seen singly or in pairs, but occasionally in groups of up to four individuals, apparently families. It usually walks on the ground and can easily run faster than a human in its habitat. It will flee a car on foot at speeds up to 25 km/h (15 mph) before flying.Territorial defense may involve agonistic confrontation between individuals, initially characterized by full vocalization duets followed by short runs and flights towards intruders, alternated with claws and beak attacks. In one conflict between two birds, they jumped at each other feet-first, keeping their balance by flapping.This species typically nests on low trees or bushes, so that adults are able to reach the nest from the ground by short hops or flutters rather than by flying.
+
+
+== Vocalization ==
+Full vocalization by the seriema is mainly done at dawn and to a lesser extent, during at dusk. It can also occur irregularly at other times of day.The song has a quality described as "a cross between 'the serrated bark of a young dog and the clucking of turkeys'". At the loudest part of the song, the bird has its neck bent so its head is touching its back. Both members of a pair as well as young down to the age of two weeks sing; often one member of a family starts a song just as another finishes, or two sing simultaneously. The song can be heard several kilometers away; in Emas National Park, Brazil, in 1981–1982, observers often heard four red-legged seriemas or groups singing at once.The full song consists of three sections:
+
+Repeated single notes at constant pitch (1,200 to 1,300 Hz) and duration but increasing tempo
+Repeated two- or three-note subphrases of slightly higher pitch with increasing tempo
+Subphrases of up to 10 notes, shorter ones rising in pitch and longer ones falling, two-subphrase combinations increasing in number of notes and tempo and then decreasing in tempo.Their song was notably sampled by Boards of Canada on their track "Happy Cycling" on their debut album Music Has the Right to Children, which was taken from the Vangelis album La Fête Sauvage.
+
+
+== Diet ==
+Red-legged seriemas are omnivorous, probably eating prey in response to its abundance. Diets mainly consist of arthropods (such as grasshoppers, beetles, ants and spiders), insect larvae, lizards, amphibians, snakes, rodents and other small vertebrates; occasionally, corn (Zea) grains and other crops, wild fruits and tree gum. In captivity, and probably even in the wild, eggs and chicks of other bird species are also eaten.Typically feeds alone or in pairs, seasonally in small family groups; forages walking steadily, looking for food on the ground or in low vegetation. Foraging birds sometimes stays obscured due to cryptic plumage colours. It grabs small vertebrates in its beak and beats them against the ground before dismembering them with its beak and claws.
+During a long term study in Arcos municipality, Minas Gerais, Brazil, a research team placed a camera trap at one of 44 seriema nests in their study area. On 29 September 2018 it recorded a 20 minute video of an adult killing one of three nestlings, eating part of it, and allowing the other two nestlings to feed on the carcass. It was the first documented parental infanticide and cannibalism by the species in the wild though it had been observed in a captive individual. The researchers note that very few red-legged seriema broods fledge three young and speculate that the third nestling serves as reserve food for the other two in times of stress.
+
+
+== Reproduction ==
+Seriemas are monogamous. In the wild, the breeding season correlates to the rainy months of February to July in the northeast of Brazil, September to January in central Brazil and November to December in Argentina.During the breeding season, the male, more intimidating or forcing himself on the female, spreads out his wings laterally, moving them forward and displaying the contrasting arrangement of the flight feathers, a pattern similar to that of certain birds of prey, such as the African secretarybird (Sagittarius serpentarius). The display is often followed by a strut in front of the female, with the head pointing and the crest lifted. The male also gives food (from the normal diet) to the female. Both birds call, thereby reinforcing the bond between them as well as establishing the territories of the pair. Copulation takes place on the ground.Typically, 2–3 white, softly spotted eggs are laid. Incubation is done by both sexes, lasting 24–30 days. The chicks are coated with long, light brown feathers and are fed by both parents; initially, they weigh around 40–60 g (1.4–2.1 oz). At around 14 days of age, the chicks are able to leave their nests. At this time, the chick is able to make a call similar to the adult vocalization, although very faint, to attract the parents' attention to itself. Adult plumage is obtained in 4–5 months.

+The southern white rhinoceros or southern white rhino (Ceratotherium simum simum) is one of the two subspecies of the white rhinoceros (the other being the much rarer northern white rhinoceros). It is the most common and widespread subspecies of rhinoceros.
+A document published by CITES in 2021, found the estimated total population of Southern White Rhino in 2021 to be 15,940 individuals, a decline of 24% since the previous census published in 2015. South Africa remains a stronghold for this subspecies, conserving an estimated 12,968 individuals as of 2021, down 20.22% since the previous census.
+
+
+== Taxonomic and evolutionary history ==
+The southern white rhinoceros is the nominate subspecies; it was given the scientific name Ceratotherium simum simum by the English explorer William John Burchell in the 1810s. The subspecies is also known as Burchell's rhinoceros (Ceratotherium simum burchellii) after Burchell and Oswell's rhinoceros (Ceratotherium simum oswellii) after William Cotton Oswell, respectively. However, these are considered synonyms of its original scientific name.
+Ceratotherium simum kiaboaba (or Rhinoceros kiaboaba), also known as straight-horned rhinoceros, was proposed as a different subspecies (or species) found near Lake Ngami and north of the Kalahari desert. However, it is now considered part of the southern white rhinoceros.
+Following the phylogenetic species concept, research in 2010 suggested the southern and northern white rhinoceros may be different species, rather than subspecies, in which case the correct scientific name for the northern subspecies is Ceratotherium cottoni and the southern subspecies should be known as simply Ceratotherium simum. Distinct morphological and genetic differences suggest the two proposed species have been separated for at least a million years.
+
+
+== Physical descriptions ==
+
+The southern white rhinoceros is one of largest and heaviest land animals in the world. It has an immense body and large head, a short neck and broad chest. Females weigh around 1,700 kg (3,750 lb) and males around 2,300 kg (5,070 lb). The head-and-body length is 3.4–4 m (11.2–13.1 ft) and a shoulder height of 160–186 cm (5.25–6.10 ft). It has two horns on its snout. The front horn is larger than the other horn and averages 60 cm (24 in) in length and can reach 150 cm (59 in). Females usually have longer but thinner horns than the males, who have larger but shorter ones. The southern white rhinoceros also has a prominent muscular hump that supports its large head. The colour of this animal can range from yellowish brown to slate grey. Most of its body hair is found on the ear fringes and tail bristles, with the rest distributed sparsely over the rest of the body. The southern white rhino has a distinctive flat, broad mouth that is used for grazing.Southern white rhinos are strictly herbivores (graminivores) that feed on short grasses.
+
+
+== Mating and reproduction ==
+Little is known about Southern White Rhinoceros mating habits,but females reproduce every 2-3 years.They give birth to a single calf after the gestation period that lasts around 16 months. Newborn calves weigh about 45 kg (100 pounds) at birth. Young usually become independent in 2-3 years.
+.
+
+
+== Habitat and distribution ==
+
+The southern white rhino lives in the grasslands, savannahs, and shrublands of southern Africa, ranging from South Africa to Zambia. About 98.5% of southern white rhino live in just five countries: South Africa, Namibia, Zimbabwe, Kenya and Uganda. 
+The southern white rhino was nearly extinct in the early 20th century, with less than 20 individuals in a single South African reserve. The small population of white rhinoceros slowly recovered over the years, growing to 840 individuals in the 1960s and to 1,000 in the 1980s. White rhino trophy hunting was legalized and regulated in 1968, and after initial miscalculations is now generally seen to have assisted in the species' recovery by providing incentives for landowners to boost rhino populations. In 2001, it was estimated that there were 11,670 white rhinos in the wild of southern Africa with a further 777 individuals in captivity worldwide, making it the most common rhinoceros in the world. By the end of 2007, wild-living southern white rhinos had increased to an estimated 17,480 animals. In 2015, there was an estimated population of 19,682–21,077 in the wild.
+
+
+== Threats ==
+
+The southern white rhinoceros is listed as Near Threatened; it is mostly threatened by habitat loss, continuous poaching in recent years, and the high illegal demand for rhino horn for commercial purposes and use in traditional Chinese medicine.
+
+
+== Conservation status ==
+
+
+=== Introduction/reintroduction projects ===
+
+There are smaller reintroduced populations within the historical range of the southern white rhinoceros in Namibia, Botswana, Zimbabwe, Eswatini, Zambia and in southwestern Democratic Republic of the Congo, while a small population survives in Mozambique. Populations have also been introduced outside of the former range of the species to Kenya, Uganda and Zambia, where their northernmost relatives used to occur. The southern white rhinoceros have been reintroduced in the Ziwa Rhino Sanctuary in Uganda, and in the Lake Nakuru National Park and the Kigio Wildlife Conservancy in Kenya.
+In 2010, nine southern white rhinoceros were imported from South Africa and shipped to the Yunnan province from southeast China where they were kept in an animal wildlife park for acclimation. In March 2013, seven of the animals were shipped to the Laiyanghe National Forest Park, a habitat where Sumatran and Javan rhinoceros once lived. Two of the southern white rhinos began the process of being released into the wild on May 13, 2014.
+
+
+=== In captivity ===
+Wild-caught southern white rhinoceros will readily breed in captivity given appropriate amounts of space and food, as well as the presence of other female rhinos of breeding age. Many rhinoceros living in zoos today are a part of a cooperative breeding program to increase population numbers and maintain genetic diversity without pulling individuals from the wild. For instance, 96 calves have been born at the San Diego Zoo Safari Park since 1972. However, the rate of reproduction is fairly low among captive-born southern white females, potentially due to their diet. Ongoing research through San Diego Zoo Global is hoping to not only focus on this, but also on identifying other captive species that are possibly affected and developing new diets and feeding practices aimed at enhancing fertility. When managed correctly the rate of natural reproduction among captive-born southern white females is relatively good as can be seen by the success of John Frederik Hume's rhino breeding initiative, which currently has an average of 200 natural births per year and has seen more than 1800 natural births since 1993. In South Africa a population of southern white rhinos are being raised on farms and ranches for their horns along with the black rhino.

+The white rhinoceros, white rhino or square-lipped rhinoceros (Ceratotherium simum) is the largest extant species of rhinoceros. It has a wide mouth used for grazing and is the most social of all rhino species. The white rhinoceros consists of two subspecies: the southern white rhinoceros, with an estimated 19,682–21,077 wild-living animals in the year 2015, and the much rarer northern white rhinoceros. The northern subspecies has very few remaining individuals, with only two confirmed left in 2018 (two females: Fatu, 18 and Najin, 29), both in captivity. Sudan, the world's last known male Northern white rhinoceros, died in Kenya on 19 March 2018 at age 45.
+
+
+== Naming ==
+
+A popular albeit widely discredited theory of the origins of the name "white rhinoceros" is a mistranslation from Dutch to English. The English word "white" is said to have been derived by mistranslation of the Dutch word "wijd", which means "wide" in English. The word "wide" refers to the width of the rhinoceros' mouth. So early English-speaking settlers in South Africa misinterpreted the "wijd" for "white" and the rhino with the wide mouth ended up being called the white rhino and the other one, with the narrow pointed mouth, was called the black rhinoceros. Ironically, Dutch (and Afrikaans) later used a calque of the English word, and now also call it a white rhino. This suggests the origin of the word was before codification by Dutch writers. A review of Dutch and Afrikaans literature about the rhinoceros has failed to produce any evidence that the word wijd was ever used to describe the rhino outside of oral use.An alternative name for the white rhinoceros, more accurate but rarely used, is the square-lipped rhinoceros. The white rhinoceros' generic name, Ceratotherium, given by the zoologist John Edward Gray in 1868, is derived from the Greek terms keras (κέρας) "horn" and thērion (θηρίον) "beast". Simum, is derived from the Greek term simos (σιμός), meaning "flat nosed".
+
+
+== Taxonomy and evolution ==
+
+The white rhinoceros of today was said to be likely descended from Ceratotherium praecox which lived around 7 million years ago. Remains of this white rhino have been found at Langebaanweg near Cape Town. A review of fossil rhinos in Africa by Denis Geraads has however suggested that the species from Langebaanweg is of the genus Ceratotherium, but not Ceratotherium praecox as the type specimen of Ceratotherium praecox should, in fact, be Diceros praecox, as it shows closer affinities with the black rhinoceros Diceros bicornis. It has been suggested that the modern white rhino has a longer skull than Ceratotherium praecox to facilitate consumption of shorter grasses which resulted from the long-term trend to drier conditions in Africa. However, if Ceratotherium praecox is in fact Diceros praecox, then the shorter skull could indicate a browsing species. Teeth of fossils assigned to Ceratotherium found at Makapansgat in South Africa were analysed for carbon isotopes and the researchers concluded that these animals consumed more than 30% browse in their diet, suggesting that these are not the fossils of the extant Ceratotherium simum which only eats grass. It is suggested that the real lineage of the white rhino should be; Ceratotherium neumayri → Ceratotherium mauritanicum → C. simum with the Langebaanweg rhinos being Ceratotherium sp. (as yet unnamed), with black rhinos being descended from C. neumayri via Diceros praecox.
+
+Recently, an alternative scenario has been proposed under which the earliest African Ceratotherium is considered to be Ceratotherium efficax (now synonymous with C. mauritanicum), known from the Late Pliocene of Ethiopia and the Early Pleistocene of Tanzania. This species is proposed to have been diversified into the Middle Pleistocene species C. mauritanicum in northern Africa, C. germanoafricanum in East Africa, and the extant C. simum. The first two of these are extinct, however, C. germanoafricanum is very similar to C. simum and has often been considered a fossil and ancestral subspecies to the latter. The study also doubts the ancestry of C. neumayri from the Miocene of southern Europe to the African species.
+The ancestor of both the black and the white rhinos was likely a mixed feeder, with the two lineages then specializing in browsing and grazing, respectively. The oldest definitive record of the White Rhinoceros is during the mid-Early Pleistocene at Olduvai Gorge in Tanzania, around 1.8 Ma.
+
+
+=== Southern white rhinoceros ===
+
+There are two subspecies of white rhino: the southern white rhinoceros (Ceratotherium simum simum) and the northern white rhinoceros. As of 31 December 2007, there were an estimated 17,460 southern white rhinos in the wild (IUCN 2008), making them by far the most abundant subspecies of rhino in the world; the number of southern white rhinos outnumbers all other rhino subspecies combined. South Africa is the stronghold for this subspecies (93.0%), conserving 16,255 individuals in the wild in 2007 (IUCN 2008). There are smaller reintroduced populations within the historical range of the species in Namibia, Botswana, Zimbabwe, Uganda and Eswatini, while a small population survives in Mozambique. Populations have also been introduced outside of the former range of the species to Kenya and Zambia.Wild-caught southern whites will readily breed in captivity given appropriate amounts of space and food, as well as the presence of other female rhinos of breeding age. However, for reasons that are not currently understood, the rate of reproduction is extremely low among captive-born southern white females.
+
+
+=== Northern white rhinoceros ===
+
+The northern white rhinoceros or northern square-lipped rhinoceros (Ceratotherium simum cottoni) is considered critically endangered and possibly extinct in the wild. Formerly found in several countries in East and Central Africa south of the Sahara, this subspecies is a grazer in grasslands and savanna woodlands.
+Initially, six northern white rhinoceros lived in the Dvůr Králové Zoo in the Czech Republic. Four of the six rhinos (which were also the only reproductive animals of this subspecies) were transported to Ol Pejeta Conservancy in Kenya, where scientists hoped they would successfully breed and save this subspecies from extinction. One of the two remaining in the Czech Republic died in late May 2011. Both of the last two males capable of natural mating died in 2014 (one in Kenya on 18 October and one in San Diego on 15 December). In 2015, the Kenyan government placed the last remaining male of the subspecies at Ol Pejeta under 24-hour armed guard to deter poachers, but he was put down on 19 March 2018 due to multiple health problems caused by old age, leaving just two females alive which reside at the Ol Pejeta complex.  Staff hope to inseminate the remaining females with the last male's semen, although the semen is not preferable due to the age of the rhino.Following the phylogenetic species concept, recent research has led to the hypothesis that the northern white rhinoceros is a different species, rather than a subspecies of white rhinoceros as was previously thought, in which case the correct scientific name for the former should be Ceratotherium cottoni. Distinct morphological and genetic differences suggest the two proposed species have been separated for at least a million years. However, the results of the research were not universally accepted by other scientists.
+
+
+== Description ==
+
+The white rhinoceros is the largest of the five living species of rhinoceros. By mean body mass, the white rhinoceros falls behind only the three extant species of elephant as the largest land animal and terrestrial mammal alive today. It weighs slightly more on average than a hippopotamus despite a considerable mass overlap between these two species. It has a massive body and large head, a short neck and broad chest.
+
+The head and body length is 3.7 to 4 m (12.1 to 13.1 ft) in males and 3.4 to 3.65 m (11.2 to 12.0 ft) in females, with the tail adding another 70 cm (28 in) and the shoulder height is 170 to 186 cm (5.58 to 6.10 ft) in the male and 160 to 177 cm (5.25 to 5.81 ft) in the female. The male, averaging about 2,300 kg (5,070 lb) is heavier than the female, at an average of about 1,700 kg (3,750 lb). The largest size the species can attain is not definitively known; specimens of up to 3,600 kg (7,940 lb) are considered reliable, while larger sizes up to 4,500 kg (9,920 lb) have been claimed but are not verified. On its snout it has two horn-like growths, one behind the other. These are made of solid keratin, in which they differ from the horns of bovids (cattle and their relatives), which are keratin with a bony core, and deer antlers, which are solid bone.
+
+The front horn is larger and averages 60 cm (24 in) in length, reaching as much as 150 cm (59 in) but only in females. The white rhinoceros also has a noticeable hump on the back of its neck. Each of the four stumpy feet has three toes. The color of the body ranges from yellowish-brown to slate grey. Its only hair is the ear fringes and tail bristles. White rhinos have a distinctive broad, straight mouth which is used for grazing. Its ears can move independently to pick up sounds, but it depends most of all on its sense of smell. The olfactory passages that are responsible for smell are larger than their entire brain. The white rhinoceros has the widest set of nostrils of any land-based animal.
+
+
+== Genome ==
+
+The genome size of the white rhinoceros is 2581.22 Mb. A diploid cell has 2 x 40 autosomals and 2 sex chromosomes (XX or XY).
+
+
+== Behavior and ecology ==
+White rhinos are found in grassland and savannah habitat. Herbivore grazers that eat grass, preferring the shortest grains, the white rhinoceros is one of the largest pure grazers. It drinks twice a day if water is available, but if conditions are dry it can live four or five days without water. It spends about half of the day eating, one-third resting, and the rest of the day doing various other things. White rhinos, like all species of rhinoceros, love wallowing in mud holes to cool down. The white rhinoceros is thought to have changed the structure and ecology of the savanna's grasslands. Comparatively, based on studies of the African elephant, scientists believe the white rhino is a driving factor in its ecosystem. The destruction of the megaherbivore could have serious cascading effects on the ecosystem and harm other animals.
+
+White rhinos produce sounds which include a panting contact call, grunts and snorts during courtship, squeals of distress, and deep bellows or growls when threatened. Threat displays (in males mostly) include wiping its horn on the ground and a head-low posture with ears back, combined with snarl threats and shrieking if attacked. The vocalizations of the two species differ between each other, and the panting contact calls between individual white rhinos in each species can vary as well. The differences in these calls aid the white rhinos in identifying each other and communicating over long distances. The white rhinoceros is quick and agile and can run 50 km/h (31 mph).
+White rhinos live in crashes or herds of up to 14 animals (usually mostly female). Sub-adult bulls will congregate, often in association with an adult cow. Most adult bulls are solitary. Dominant bulls mark their territory with excrement and urine. The dung is laid in well defined piles. It may have 20 to 30 of these piles to alert passing white rhinos that it is his territory. Another way of marking their territory is wiping their horns on bushes or the ground and scraping with their feet before urine spraying. They do this around ten times an hour while patrolling territory. The same ritual as urine marking except without spraying is also commonly used. The territorial male will scrape-mark every 30 m (98 ft) or so around its territory boundary. Subordinate males do not mark territory. The most serious fights break out over mating rights with a female. Female territory overlaps extensively, and they do not defend it.
+
+
+=== Reproduction ===
+
+Females reach sexual maturity at 6–7 years of age while males reach sexual maturity between 10 and 12 years of age. Courtship is often a difficult affair. The bull stays beyond the point where the cow acts aggressively and will give out a call when approaching her. The bull chases and or blocks the way of the cow while squealing or wailing loudly if the cow tries to leave his territory. When ready to mate the cow curls her tail and gets into a stiff stance during the half-hour copulation. Breeding pairs stay together between 5–20 days before they part their separate ways. The gestation period of a white rhino is 16 months. A single calf is born and usually weighs between 40 and 65 kg (88 and 143 lb). Calves are unsteady for their first two to three days of life. When threatened, the baby will run in front of the mother, which is very protective of her calf and will fight for it vigorously. Weaning starts at two months, but the calf may continue suckling for over 12 months. The birth interval for the white rhino is between two and three years. Before giving birth, the mother will chase off her current calf. White rhinos can live to be up to 40–50 years old.Adult white rhinos have no natural predators (other than humans) due to their size, and even young rhinos are rarely attacked or preyed on due to the mother's presence and their tough skin. One exceptional successful attack was perpetrated by a lion pride on a roughly half-grown white rhinoceros, which weighed 1,055 kg (2,326 lb), and occurred in Mala Mala Game Reserve, South Africa.
+
+
+== Distribution ==
+
+The southern white rhino lives in Southern Africa. About 98.5% of white rhinos live in just five countries (South Africa, Namibia, Zimbabwe, Kenya, and Uganda). Almost at the edge of extinction in the early 20th century, the southern subspecies have made a tremendous comeback. In 2001 it was estimated that there were 11,670 white rhinos in the wild with a further 777 in captivity worldwide, making it the most common rhino in the world. By the end of 2007 wild-living southern white rhinos had increased to an estimated 17,480 animals (IUCN 2008).
+The northern white rhino (Ceratotherium simum cottoni) formerly ranged over parts of northwestern Uganda, southern Chad, southwestern Sudan, the eastern part of Central African Republic, and northeastern Democratic Republic of the Congo (DRC). The last surviving population of wild northern white rhinos are or were in Garamba National Park, Democratic Republic of the Congo (DRC) but in August 2005, ground and aerial surveys conducted under the direction of African Parks Foundation and the African Rhino Specialist Group (ARSG) only found four animals: a solitary adult male and a group of one adult male and two adult females. In June 2008 it was reported that the species may have gone extinct in the wild.Like the black rhino, the white rhino is under threat from habitat loss and poaching, most recently by Janjaweed. Although there are no measurable health benefits, the horn is sought after for traditional medicine and jewelry.
+
+
+== Poaching ==
+
+Historically the major factor in the decline of white rhinos was uncontrolled hunting in the colonial era, but now poaching for their horn is the primary threat. The white rhino is particularly vulnerable to hunting because it is a large and relatively unaggressive animal with very poor eyesight and generally lives in herds.
+Despite the lack of scientific evidence, the rhino horn is highly prized in traditional Asian medicine, where it is ground into a fine powder or manufactured into tablets to be used as a treatment for a variety of illnesses such as nosebleeds, strokes, convulsions, and fevers. Due to this demand, several highly organized and very profitable international poaching syndicates came into being and would carry out their poaching missions with advanced technologies ranging from night vision scopes, silenced weapons, darting equipment, and even helicopters. The ongoing civil war in the Democratic Republic of Congo and incursions by poachers primarily coming from Sudan have further disrupted efforts to protect the few remaining northern rhinos.In 2013, poaching rates for white rhinos nearly doubled from the previous year. As a result, the white rhino has now received Near Threatened status as its total population tops out at 20,000 members. Poaching of the animal has gone virtually unchecked in most of Africa, and the non-violent nature of the rhinoceros makes it susceptible to poaching. Mozambique, one of the four main countries the white rhino lives in, is used by poachers as a passageway to South Africa, which holds a fairly large number of white rhinos. Here, rhinos are regularly killed and their horns are smuggled out of the country. As of 2014, Mozambique labels white rhino poaching as a misdemeanor. The white rhino population in South Africa's Kruger National Park fell by 60% between 2013 and 2021, to an estimated 3529 individuals.In March 2017 the Thoiry Zoo, located in France, was broken into by poachers. A Southern white rhinoceros named Vince was found shot dead in his enclosure; the poachers had removed one of his horns and had attempted to remove his second horn. This is believed to be the first time a rhinoceros had been killed in a European zoo.Even with increased anti-poaching efforts in many African countries, many poachers are still willing to risk death or prison time because of the tremendous amount of money that they stand to make. Rhino horn can fetch tens of thousands of dollars per kilogram on the black market in Asia and, depending on the exact price, can be worth more than its weight in gold. Poachers are also starting to use social media sites for obtaining information on the location of rhino in popular tourist attractions (such as Kruger National Park) by searching for geotagged photographs posted online by unsuspecting tourists. By using GPS coordinates of rhinos in recent photographs, poachers can more easily find and kill their targets.
+
+
+== Modern conservation tactics ==
+
+The northern white rhino is critically endangered to the point that only two of these rhinos are known to remain in the world, both in captivity. Several conservation tactics have been taken to prevent this subspecies from disappearing from the planet. Perhaps the most notable type of conservation effort for these rhinos is having moved them from Dvur Kralove Zoo in the Czech Republic to Kenya's Ol Pejeta Conservancy on 20 December 2009, where they have been under constant watch every day, and have been given favorable climate and diet, to which they have adapted well, to boost their chances of reproducing.
+To save the northern white rhino from extinction, Ol Pejeta Conservancy announced that it would introduce a fertile southern white rhino from Lewa Wildlife Conservancy in February 2014. They placed the male rhino in an enclosure with both female northern white rhinos in hopes to cross-breed the subspecies. Having the male rhino with two female rhinos was expected to increase competition for the female rhinos and in theory, should result in more mating experiences. Ol Pejeta Conservancy did not announce any news of rhino mating.On 22 August 2019, using (ICSI), eggs from Fatu and Najin "were successfully inseminated" using the seminal fluid from Saut and Suni. The male Sudan's sperm was harvested before his death and is still in Kenya. On 11 September 2019, it was announced that "two embryos" were generated and will be kept in a frozen state, until placed in a surrogate female. On 15 January 2020, it was announced that "another embryo" was created using the same techniques; all three embryos are "from Fatu".
+
+
+== In captivity ==
+
+Most white rhinos in zoos are southern white rhinos; in 2001 it was estimated that there were 777 white rhinos in captivity worldwide.The San Diego Zoo Safari Park in San Diego, California, US had two northern white rhinos, one of which was wild-caught. On 22 November 2015, a 41-year-old female named Nola (born in 1974), which had been on loan from the Dvůr Králové Zoo in Dvůr Králové, Czech Republic) since 1989, was euthanized after experiencing a downturn in health. On 14 December 2014, a 44-year-old male named Angalifu died of old age at the San Diego Zoo. The other four captive northern white rhinos were loaned to Ol Pejeta Conservancy in Kenya, and only two remain alive. Females Najin and Fatu are still living, while males Suni and Sudan died in 2014 and 2018, respectively. The northern white rhinos had been transferred to Ol Pejeta Conservancy from the Dvůr Králové Zoo in 2009 in an attempt to protect the taxa in their natural habitat. The only two northern white rhinos left are maintained under 24-hour armed guard in Kenya.

+The red-tailed monkey (Cercopithecus ascanius), also known as the black-cheeked white-nosed monkey, red-tailed guenon, redtail monkey, or Schmidt's guenon, is a species of primate in the family Cercopithecidae.
+It is found in Angola, Cameroon, Central African Republic, Democratic Republic of the Congo, Kenya, Rwanda, South Sudan, Tanzania, Uganda, Zambia, and possibly Burundi. The red-tailed monkey is usually black, red, or orange. Although native to this region, it has spread north and south as well as it can survive in different habitats and under different conditions. It is a distinct creature in its habitats and is gradually becoming endangered due to deforestation and over-exploitation through hunting and predation.
+
+
+== Taxonomy and classification ==
+There are five subspecies recognized for this species:
+
+Cercopithecus ascanius ascanius
+Cercopithecus ascanius atrinasus
+Cercopithecus ascanius katangae
+Cercopithecus ascanius whitesidei
+Cercopithecus ascanius schmidti
+
+
+== Anatomy ==
+
+
+=== Distinguishing features ===
+
+The red-tailed monkey is named as it sounds, for its red coloration of the tail's underside as well as the bi-coloration of the tail as the reddish color increases from the base to the tip. There are other features characteristic to this mammal as well such as the white nose and cheeks in the midst of black or dark grey body fur. Red-tailed monkeys also have very large, elastic cheeks which are used in gathering food and storing it in their mouths for safety.
+
+
+=== Size ===
+Sizes of their bodies range between individuals as well as between the sexes as males are larger than the females. Body length ranges from 1 to 2 foot (12-24 inches), without the tail included, males being on the upper end of the scale and females being on the lower. Adult males also weigh between 7 and 10 pounds and females weigh slightly less between 6 and 8 pounds. The tail length can reach up to 35 inches long which can be twice the body length for some red-tailed monkeys. The tail helps the monkeys achieve balance.
+
+
+== Behavior ==
+
+
+=== Communication and vocalization ===
+Red-tailed monkeys communicate using different methods which are characteristic of communicating specific behaviors or things. Physical and vocal communication are used between members of social groups of these monkeys to demonstrate social dominance, submissiveness, or greeting. Vocal communication is used between members of social groups of red-tailed monkeys in which the more submissive monkey will make a soft, oscillating call to its elder. Physical communication is exhibited in nose to nose greetings where two red-tailed guenons touch their noses together. This is a sign of affection and can be followed by playful behavior. Visual communication is used as a sign of warning to others to stay away and as a defense against predators. Red-tailed monkeys practice staring or staring with their mouth open. When these monkeys implement staring, they lift their eyebrows to retract the skin on their forehead which makes the skin on the face expand backwards revealing the underneath of their eyelids. On the dark fur background, their eyelids can be seen very easily by others and understand it as a display that the red-tailed monkey is being  threatened and the other species needs to stay away. Head-bobbing is another threat display in which the monkey moves its head up and down. These types of communication can be used separately or together depending on how  threatened the monkey feels to its surroundings. Other types of communication are used such as chemical and olfactory communication; however, not much information is available on this type of communication.
+
+
+=== Feeding habits ===
+Red-tailed monkeys are primarily fructivorous, but are considered omnivorous because they will eat leaves, flowers, or insects in times where fruit is scarce. As they forage, these monkeys gather their findings in the expandable cheeks of their mouths. The pouches will hold a large amount of food where they can forage in one area and then carry their food away to another location where it is safe to consume without the threat of another stealing from them.
+
+
+=== Social structure ===
+Red-tailed monkeys are social primates that form groups that can range in size from 7 to 30 individuals. The groups consist of one dominant male and females and their offspring, male or female juveniles. Groups generally stay together through all periods of the day and through life, except for males who reach maturity. These males will leave the group they were born into and go on to form all male groups with other red-tailed monkey males or survive alone until they can replace the dominant male of a different social group. The females practice allomaternal care in which the various females in a group will help take care of their own young as well as the young of other females in the group. Often, the different social groups will congregate for support from each other when food is unlimited and in abundance.Red-tailed monkeys have been observed interacting with blue monkeys, including interspecies grooming.
+
+
+=== Activity and habitat ===
+Red-tailed monkeys are active in the early morning and evening which is characterized as diurnal activity. They act as important seed dispersers as they collect fruit and other food items. Their dispersal is throughout the tropical forest of in East and Central Africa ranging to Kenya and many areas of the Congo. The red-tailed monkey species is categorized in recognized subspecies and these subspecies have different ranges, the subspecies C. a. schmidti having the widest distribution from Congo into countries of Kenya, Tanzania, and Uganda and the subspecies C. a. atrinasus having the smallest distribution restricted to a local habitat of Zovo, Angola. They are primarily arboreal but will come to the ground. In the trees, they are very active and travel at greater speeds than being on the ground. On the ground, they travel quadrupedally, on all four legs. While they show a dominating preference for being arboreal in activity and where they choose to rest, they forage on the ground and as a result, they spend an adequate amount of their time on the forest floor as well.
+
+
+== Reproduction ==
+Like all placental mammals, red-tailed monkeys produce viviparous young. They tend to only give birth to a single young per mating season. Their mating system is characterized as polygynous meaning that one male mates with multiple females and is a common sight in mammals due to advantages of the grouped social system. The most prominent and successful mating season is from the month of November extending into the month of February; however, breeding can occur throughout the course of an entire year. In some studies, it has been seen that the red-tailed monkey will interbreed and hybridize with another species in its genus: the blue monkey (C. mitis). The hybrids have been seen on the terrestrial island of Gombe, Tanzania, and this hybridization could serve a vital purpose in the reproduction of both the red-tailed and blue monkey species, and quite possibly, produce a new species in the future.
+
+
+== Conservation status ==
+Conservation efforts for the red-tailed monkey are of "least concern" as listed by the IUCN Red List of Threatened Species. This has been justified because this species of monkey is located at many different habitats throughout the Congo and throughout East-Central Africa. Also, the species is quite abundant in these areas and they have an average lifespan of about 28 years. The red-tailed monkey is subject to predation by crowned eagles, wild cats, and occasionally, humans and chimpanzees. Despite the influence of predation on their population, no major threat to this species in terms of endangerment is posed, although some locations of their habitat suffer from deforestation and hunting pressure as well.

+The Diana monkey (Cercopithecus diana) is an Old World monkey found in the high canopy forests in Sierra Leone, Liberia, and western Côte d’Ivoire. Named for its white brow which is said to resemble the bow of the Roman goddess Diana, this black-grey guenon has a white throat, crescent-shaped browband, ruff and beard.
+
+
+== Taxonomy ==
+Two taxa formerly considered subspecies of the Diana monkey have recently been elevated to full species status: the roloway monkey (C. roloway) is found in Côte d'Ivoire and Ghana, and the Dryas monkey (C. dryas) found in the DR Congo.
+
+
+== Distribution ==
+This species can be found in West Africa, from Sierra Leone to Côte d'Ivoire.
+
+
+== Habitat ==
+The Diana monkey is found in the primary forests, and does not thrive in secondary forests.  The species is regarded as endangered by the IUCN as well as by the United States Fish and Wildlife Service, the chief dangers to them being habitat destruction (they are now virtually confined to coastal areas) and hunting for bushmeat.
+
+
+== Description ==
+The Diana monkey ranges from 40 to 55 cm in length, excluding its tail, which is of a uniform 3–4 cm diameter and 50–75 cm long. Adults weigh between 4–7 kg.
+They are generally black or dark grey, but have a white throat, crescent-shaped browband, ruff and beard; the browband gave the species its common name, since it was held to resemble the crescent on the brow of the goddess Diana. The monkeys' underarms are also white, and they have a white stripe down their thighs, while the backs of their thighs, and their lower backs, are a chestnut colour. Apart from the browband, ruff and beard, and some fringes on their limbs, their fur is rough and tough.
+
+
+== Biology and behavior ==
+Individual Diana monkeys may live for up to 20 years. This monkey is active during the day. It feeds at all levels of the canopy, and rarely comes down to the ground. Diana monkeys retreat to the upper levels of the trees at night, though they do not make nests. They feed mainly on fruit and insects, but also take flowers, young leaves, and invertebrates, and are in turn preyed on by the crowned hawk-eagle, the leopard, the common chimpanzee, and humans.
+The Diana monkey is a noisy presence in the forest. Its marked coloration allows a wide range of visual social signals. Female Diana monkeys produce specific alarm calls, alert calls and contact calls depending on the differences in predator fauna, suggesting that the flexibility of female calls are better than that of males. Other forest residents such as the yellow-casqued hornbill are able to discriminate these and take appropriate action.Diana Monkeys communicate both to local group members and distant competitors with different kind of alarm sounds. Diana Monkeys produce loud noises to make other monkeys aware of leopards or other competitors in their area. 
+Groups consist of a single male with a number of reproducing females and their infants. In good conditions, adult females reproduce annually. Gestation lasts about 5 months, and the young nurse for a further 6 months. Normally, only a single infant is born. Although the young are born in a fairly well-developed condition, with open eyes and able to grasp their mothers, at least in zoo conditions, Diana monkey mothers appear anxious and possessive, rarely letting young infants leave them. As infants grow, however, they become very playful. Juveniles reach sexual maturity at an age of about 3 years. Daughters remain in their mothers' social groups, while males leave their natal groups shortly before attaining sexual maturity.
+
+
+== Human relevance ==
+Like most primates, Diana monkeys can carry diseases that can be communicated to humans, like yellow fever and tuberculosis. Native tribes in the tropical forest of West Africa poach Diana monkeys, which are sold as luxury meat and seen as a commodity.

+De Brazza's monkey (Cercopithecus neglectus) is an Old World monkey endemic to the riverine and swamp forests of central Africa. The largest species in the guenon family, it is one of the most widespread arboreal African primates. Aside from size, it can be differentiated from other cercopithecus monkeys by its orange diadem and white beard. Due to its cryptic nature, the species is not well documented in all of its habitats but has shown unique traits such as pair-bonding and aggressive behavior towards other guenons.
+
+
+== Etymology ==
+Locally known as swamp monkeys, these primates are named after the Italian naturalist and explorer Jacques Savorgnan de Brazza. 
+Their scientific species name, neglectus, which means to pay no attention to, was given to them because of their ability to hide from both humans and predators.
+
+
+== Description ==
+
+The De Brazza's monkey is the most sexually dimorphic species of guenon; males weigh around 7 kilograms, while females weigh around 4 kilograms. Adults have grey agouti fur with a reddish-brown back, black limbs and tail, and a white rump. Both sexes have cheek pouches they use to carry food while they forage. Males have a distinct blue scrotum, while females have a red perianal region and visible nipples. Juveniles lack the darker colors on the extremities that is characteristic of adults, but retain the whites stripes and red rump while infants are a uniform brown agouti with only a small beard. The white muzzle and beard, along with an orange crescent on its forehead and white stripes on its thighs distinguish it from other guenons. Due to this distinctive appearance, the monkey is sometimes referred to as the "Ayatollah Monkey" after the similarly-bearded Grand Ayatollah Ruhollah Khomeini.
+
+
+== Ecology ==
+
+
+=== Distribution and habitat ===
+De Brazza's monkeys range across the swamps, bamboo and dry mountain forests of Angola, Cameroon, Central African Republic, Congo, The Democratic Republic of the Congo, Equatorial Guinea, Ethiopia, Gabon, Kenya, South Sudan, Nigeria and Uganda and possibly Tanzania though reports have not been confirmed. Troops are found almost exclusively near water, rarely venturing farther than 1 km away from a river or tributary. As a result they can sometimes be seen swimming. The monkeys prefer dense forest and vegetation, only venturing into more open forest to feed. They are mainly arboreal, but descends to the ground to feed on herbaceous plants. Due to its cryptic nature there is no accurate population estimate for the species over its entire range.
+
+
+=== Diet ===
+The diet of De Brazza's monkeys consists mostly of herbaceous plants found on the forest floor, and fruits when available. These are supplemented with insects, seeds, and other food sources when primary foods are scarce.
+
+
+=== Predators ===
+Predators of the De Brazza's monkey include the crowned eagle, leopard, humans, and common chimpanzees. Though rare, dogs and pythons may also predate on juvenile De Brazza's. The typical predator response is to curl up in a tight ball against the side of a tree with the orange crown and white stripes on the thighs hidden and wait silently for the predator to leave. Individuals will only move if the predator approaches their position, and even then they move quietly and slowly to try and escape notice.
+
+
+== Behavior ==
+
+The lifespan of the De Brazza's monkey is thought to correspond similarly to other members of Cercopithecus which live up to 22 years in the wild and 30 years in captivity. Its cryptic nature makes the De Brazza's monkey hard to observe in the wild. Troop sizes are small for a guenon, ranging from 2-10 individuals on average. In some areas of Western Africa, such as Gabon and Cameroon, small pair-bonded groups of a male, female, and infants and juveniles have been observed. In Eastern Africa, the DeBrazza's monkeys live in single male, multi-female groups. Solitary males do not create bachelor groups and will occasionally depose an alpha male to take over access to the females.Male De Brazza's monkey communicates with booming sounds. These are usually heard early in the morning when the male calls out to establish his territory, though he will also use this call to bring the group back together if they get separated. When attacked by predators, males will give an alarm call. In the case of crowned eagles, males will emit a short bark before attacking the eagle to scare it off. Females have also been observed to give alarms calls and growl at humans. Otherwise, female vocalizations are limited to quiet croaks given when feeding or resting. Infants and juveniles will give shrill squeals of distress when separated from their mothers or the group. Given the cryptic nature of this species, hearing their calls is sometimes the only way to know they are present. Unlike other guenons, which often form polyspecific associations to decrease predation and increase foraging, DeBrazza's monkeys will be aggressive towards other species and have only been known to tolerate some colobine species which do not compete with them for resources.
+
+
+=== Reproduction ===
+Female De Brazza's monkeys reach sexual maturity around 5 years of age, while males do not reach maturity until closer to 6 years of age. Most juveniles males will leave their natal group before they reach maturity. The breeding season lasts from February to March, but females can also go into estrous during times of high food availability. Gestation lasts between 5 to 6 months, and an infant stays close to its mother for the first year of its life at which point it is weaned. Females usually have one infant at a time, though twins have been born on rare occasions, with a year long inter-birth interval.
+
+
+== Conservation ==
+The De Brazza's monkey is listed as least concern by the IUCN Red List. The main threats to DeBrazza's monkeys are deforestation due to logging and agriculture, and bushmeat hunting. There are several captive population housed in zoos across Europe and North America. The Association of Zoos and Aquariums (AZA) manages captive population under a species survival plan. This is unique because the species is not listed as vulnerable or endangered, but has been sponsored by the AZA to proactively prevent need for reactive conservation in the future. More data is needed to fully assess the conservation needs of this species.

+The big (or large) hairy armadillo (Chaetophractus villosus) is one of the largest and most numerous armadillos in South America. It lives from sea level to altitudes of up to 1,300 meters across the southern portion of South America, and can be found in grasslands, forests, and savannahs, and has even started claiming agricultural areas as its home. It is an accomplished digger and spends most of its time below ground. It makes both temporary and long-term burrows, depending on its food source.Armadillos are protected from predators by a series of thin, bony plates along the head and back. They reach sexual maturity at around 9 months and have been known to live over 30 years in captivity. Though this animal is routinely harvested for its meat and its shell, or simply killed by farmers, it has shown resiliency, and populations seem to be handling this exploitation well. Currently, no protective practices are in place for this armadillo, but it does live in many protected areas. This species of armadillo is a preferred research animal due to its adaptability to laboratory settings, and relative hardiness in situations of stress.
+
+
+== Description and taxonomy ==
+
+Chaetophractus villosus or the big hairy armadillo is the most abundant species of armadillo in Argentina. The armadillo's head and body are covered by protective bony plates, with its head plate being the most prominent. Along its back, flexible bands that encircle the torso allow flexibility in this otherwise stiff armor. The underside of this armadillo is densely covered in hair and this trait is how it got its common name. Long, coarse hairs also project from the bony plates, making this armadillo much hairier than other related species. The average individual grows from 26 to 34 cm (10 to 13 in) in body length, 22–40 cm (8.7–15.7 in) in extreme cases, and weighs 2 kg (4.4 lb), with a range of 1–3 kg (2.2–6.6 lb) by the time it reaches maturity. The tail measures 9 to 17 cm (3.5 to 6.7 in) long. Powerful front claws are used for both foraging and avoiding predators. The armadillo can use specially evolved membranes in its nose to obtain oxygen from the surrounding soil particles without inhaling any of the soil itself.The genus Chaetophractus consists of two or three species, C. vellerosus (the screaming hairy armadillo), C. nationi (the Andean hairy armadillo, which may actually be a population of C. vellerosus), and C. villosus. These species are recognized by the large amount of hair that extends all over their bodies, but especially on their undersides. The skulls follow the same patterns as other dasypodids, but females exhibit longer bones in the rostrocaudal plane, which is one of the key characteristics that shows the sexual dimorphism of these species. Not much is known about the cranial morphology of these species, especially bone descriptions. More research is being done to better describe these species and the skeletal differences between them.  For now, body size, habitat, and behaviors are the best way to discern the differences.
+
+
+== Diagnosis ==
+When trying to determine the differences between these species, a few noticeable traits stand out. The first difference is size; C. villosus is the larger species. It can grow to a length of 34 cm (13 in). C. vellerosus is much smaller, being able to fit in the palm of a hand when fully grown, usually weighing only a kilogram. Both species are covered with much more hair than any other armadillos, mostly sprouting from its underside or between the bony plates along its back. When C. villosus is sexually aroused with an erect penis, species determination is easier. Its penis can be as long as 35 mm, and usually remains completely withdrawn inside a skin receptacle. The lesser hairy armadillo can usually be found in higher altitudes because its smaller size and slower metabolic rate helps it survive in areas with less food.
+
+
+== Fossil record ==
+The presence of a carapace containing osteoderms is one of the very distinctive features of armadillos, and is true for fossil taxa as well. These elements are evident frequently in the paleontological record due to their resilience. Three distinct areas are recognized in these hardened plates. The outer and inner parts are made of thin, compact bone, while the middle zone is thicker and contains tissues for hair follicles and sweat glands. The presence of red bone marrow is rare in members of Chaetophractus, but widespread in Dasypus novemcinctus osteoderms. These findings propose an early split of both subfamilies and maintain the hypothesis that the Euphractinae are more derived than the Dasypodinae.C. villosus earliest known fossils were found in the Pampean region, which suggests this is where the species originated. Fossil records then indicate the migration into Patagonia as the main dispersal route, which most likely occurred after the Pleistocenic glaciations. Using molecular dating, scientists estimated the first armadillos emerged around the Cretaceous/Tertiary boundary. This was followed by the divergence of anteaters and sloths in the Early Eocene era.
+
+
+== Geographic distribution ==
+The C. villosus home range encompasses the Pampas and Patagonia as far south as Santa Cruz, Argentina and Magallanes, Chile. It is found in the Gran Chaco Province of Bolivia, Paraguay, and Argentina, and is starting to migrate south into the Tierra del Fuego province of Argentina, as well. It can be found in the Biobío province and south to Aisén Province, both in eastern Chile. Climate change, allegedly, and the opportunistic tendencies of this armadillo are allowing them to live in more areas. Unlike some other armadillos, the big hairy armadillo has not experienced drastic change in its territory. It has not migrated as far north as some other species.
+
+
+== Ecology ==
+Members of Chlamyphoridae, including C. villosus, have evolved very interesting and specific traits to help them survive. The most recognizable of these are the bony plates that cover the armadillos' heads and backs. These protective plates allow the individual a fair measure of protection against its natural predators. This species also has a remarkable respiratory adaptation when the nostrils are completely covered in soil. It is able to maintain sufficient respiratory movements due to a mechanism that allows it to use air that fills the space between soil particles, without inhaling the particles themselves. This, along with its powerful digging claws and high surface-area-to-mass ratio, contributes to this fossorial, or subterranean, lifestyle. Even with the added challenge of burrowing, this armadillo maintains similar ratios as nonfossorial species and suggests it has adapted to a burrowing lifestyle as a way to avoid extreme temperatures and predators, rather than any help it could receive from foraging.Little is known about the hemostasis of this species. Platelet counts are similar between sexes and they seem to remain similar even when in captivity. They are comparable to most other mammals and react in the same manner to proven agonists. More studies in this area could reveal biomedical advances, but little more is known now.Scientists conducting studies on the C. villosus penis muscles revealed this species' very long penis exhibits variability. During its waking hours, it remains hidden beneath a skin receptacle, until it becomes erect and it projects outside in a rostral direction. During its slow wave sleep phase, penile protrusion makes some very complex movements. The penis during this phase is not erect, but remains outside of its receptacle. During paradoxical sleep, no erections occur, and the penile muscles share the characteristics of the rest of the body.
+
+
+== Life history and behavior ==
+Chaetophractus villosus spends most of its time burrowing in the ground and looking for insects or worms as its main foraging method. Its powerful front claws and snout allow it to rout through the sediment with relative ease. When the armadillo detects a predator, it will run to the nearest burrow and wedge itself in using its legs; only the bony plates are exposed to predators. When it cannot get to one of its burrows, it will lay down flat on the ground to better protect its softer underside.Most of this armadillo's activity occurs starting at dusk and continues on into the night. It can be seen active in the day, however, when enough food cannot be found during the night. It uses its sense of smell to find prey, and shovels soil away to reach it. Most individuals breed in the late winter or spring, but in captivity they have been known to conceive year round. After a gestation period of 60 to 75 days, the female will usually give birth to a litter of one to two young which are suckled for another 50 to 80 days.C. villosus seems to be able to burrow through most sediment, but tends to shy away from rockier terrains. They tend to burrow into the side of a hill rather than on flat ground. Their temporary burrows (in search of food or safety) are usually shallower and not as complex as their home burrows, which are usually much deeper and can be quite complex, with many escape tunnels and dens. The orientation of their burrows depends largely on the wind direction. This allows them to be well adapted to arid desert terrain.
+
+
+== Conservation ==
+C. villosus is rated as a least concern species, due to its large population and widespread habitat range. It also has a remarkable ability to adapt to many changing environments. It is considered a least concern species because it is not predicted to decrease into any of the threatened categories any time soon. In fact, the population seems to be increasing.

+The Roti Island snake-necked turtle (Chelodina mccordi), also commonly known as McCord's snakeneck turtle, is a critically endangered turtle species from Rote Island in Indonesia.
+
+
+== Taxonomy ==
+Chelodina mccordi belongs to the genus Chelodina (Australian snake-necked turtles) within the family Chelidae (Austro-South American side-necked turtles).
+Chelodina mccordi was originally described from Rote Island but was later split into three subspecies. Chelodina mccordi rotensis from eastern Rote and Chelodina mccordi timorensis from Timor. In a recent paper the eastern Rote form was found to be identical to the western form and they were synonymised. This leaves the species with two subspecies one on Rote Island and one on Timor.
+
+
+== History ==
+The Roti Island snake-necked turtle was split from the New Guinea snake-necked turtle and regarded as distinct species in 1994 after Dr. Anders Rhodin, director of the Chelonian Research Foundation in Lunenburg (Massachusetts), found differences between the two species. The first snake-necked turtles on Rote Island had been discovered in 1891 by George Albert Boulenger.
+
+
+== Etymology ==
+Both the specific name, mccordi, and one of the common names, McCord's snakeneck turtle, are in honor of Dr. William Patrick McCord (born 1950), a veterinarian and turtle expert from Hopewell Junction, New York.
+
+
+== Description ==
+The carapace of C. mccordi can reach a straight length of 18–24 centimetres (7.1–9.4 in). The color of the carapace is a pale grey brown. Occasionally there are also specimens which have a chestnut-coloured hue. The plastron is a pale buff white. The neck, which is nearly as long as the carapace, is dark brown on the upperparts with round tubercles. The underparts are light beige. The iris is black surrounded by a white ring.
+
+
+== Habitat ==
+The natural habitat of Chelodina mccordi includes swamps, rice terraces, and small lakes.
+
+
+== Reproduction ==
+Adults of C. mccordi may have up to three breeding periods in a year. A typical clutch consists of eight to fourteen eggs. The size of an egg is 30 mm × 20 mm (1.18 in × 0.79 in) and may weigh 8–10 grams (0.28–0.35 oz). The first hatchlings emerge after incubating for three months, and the last hatchlings leave after four months. Upon emerging, a hatchling's shell is about 28 mm × 20 mm (1.10 in × 0.79 in) and has yellow spots on the plastron, which become darker in a few weeks until the entire plastron becomes almost black. As the juveniles grow, their coloration progressively becomes paler until they finally achieve the color of the adults.
+
+
+== Threats ==
+The Roti Island snake-necked turtle is one of the most desired turtles in the international pet trade. Even before it was scientifically described it was so over-collected that the legal trade was prohibited in 2001 due to its rarity.  The two or three remaining populations live in an area of only 70 km2 (27 square miles) in the central highlands of Rote Island. It is still illegally captured and it is often offered on markets under the label of the New Guinea snake-necked turtle which is also legally protected. In 2004 it was listed in Appendix II of CITES.
+Outside of capture by humans there are few natural threats to this species.  There are some reports of predation by feral pigs (Sus scrofa) and loss of habitat, but illegal capture and trade remain the primary threat.

+The red-footed tortoise (Chelonoidis carbonarius) is a species of tortoise from northern South America. These medium-sized tortoises generally average 30 cm (12 in) as adults, but can reach over 40 cm (16 in). They have dark-colored, loaf-shaped carapaces (back shell) with a lighter patch in the middle of each scute (scales on the shell), and dark limbs with brightly colored scales that range from pale yellow to dark red. Recognized differences are seen between red-footed tortoises from different regions. They are closely related to the yellow-footed tortoise (C. denticulatus) from the Amazon Basin. They are popularly kept as pets, and over-collection has caused them to be vulnerable to extinction.The species name has often been misspelled as carbonaria, an error introduced in the 1980s when Chelonoidis was elevated to genus and mistakenly treated as feminine, an error recognized and fixed in 2017.
+
+Their natural habitat ranges from savannah to forest edges around the Amazon Basin. They are omnivorous with a diet based on a wide assortment of plants, mostly fruit when available, but also including grasses, flowers, fungi, carrion, and invertebrates. They do not brumate, but may aestivate in hot, dry weather.
+Eggs, hatchlings, and juvenile tortoises are food for many predators, but the main threats for adults are jaguars and humans. Population density ranges from locally common to very scarce due in part to habitat destruction and over-collection for food and the pet trade.
+
+
+== Names ==
+Red-footed tortoises have many common names: red-leg, red-legged, or red-foot tortoise (often without the hyphen) and the savanna tortoise, as well as local names, such as carumbe or karumbe, which means 'slow moving' (Brazil, Paraguay), wayapopi or morrocoy (Venezuela, Colombia), and  variations of jabuti such as japuta and jabuti-piranga (Brazil, Argentina). In Portuguese, jabuti (jaboti) refers to both the red-footed tortoise and the yellow-footed tortoise.
+It is also called kati in Natú and sambó in Kiriri.
+
+
+== Taxonomy ==
+Red footed tortoises were originally assigned to the genus Testudo (named by Carl Linnaeus in 1758) for a short time, but it soon became the term for turtles with high-domed shells, elephantine legs, and completely terrestrial habits—the tortoises. In 1835, Leopold Fitzinger used Geochelone to differentiate some non-Mediterranean tortoises, apparently based on size and lack of specific identifying characteristics such as the hinged shell in the African hingeback tortoises. He used the term Chelonoidis as a subgenus for the species from South America. Few people used these terms until they were resurrected by Hewitt in 1933 and Loveridge and Williams in 1957.
+In 1982, Roger Bour and Charles Crumly each separated Geochelone into different genera based on anatomic differences, especially in the skulls. That resulted in the formation or restoration of several genera: Aldabrachelys, Astrochelys, Cylindraspis, Indotestudo, Manouria, and Chelonoidis. Chelonoidis was distinguished from other Geochelone by their South American location, as well as the absence of the nuchal scute (the marginal centered over the neck) and the presence of a large, undivided supracaudal (the scute or scutes directly over the tail), as well as differences in the skull. Many of these generic names are still debated; for example, no specific definition of Geochelone is given, and Chelonoidis is primarily used for geography rather than unique anatomic characteristics.The species name carbonarius means 'coal-like' referring to a dark coal with glowing patches. It was originally identified by Johann Baptist von Spix in 1824. The holotype was kept in the Zoologischen Sammlung des Bayerischen Staates in Munich, Germany, but was lost. Paulo Vanzolini believes it may have come from near the city of Manaus, Brazil, on the Rio Negro. No subspecies of red-footed tortoise are recognized, although many believe the species has five or more variants that may be subspecies or even separate species.
+
+
+== Description ==
+Red-footed tortoises show sex, regional, and individual variations in color, shell shape, and minor anatomical characteristics. Adult  carapaces are generally an elongated oval with sides that are nearly parallel, although the sides of males may curve inwards. They are fairly highly domed and smooth with a rather flat back (although the scutes may be raised or 'pyramided' in some individuals, especially captive specimens). Often, a high point over the hips is seen, with a small sloped section over the neck. The vertebral and costal scutes (the scutes along the center and sides of the carapace) are black or dark brown with a pale yellow areole in the center. The marginals (scutes along the edge of the carapace) 'tuck under' along the sides and flare slightly over the limbs. They are dark with the pale aureole along the middle of the lower edge. The nuchal scute (the marginal over the neck) is absent, and the marginals over the tail are joined as one large supracaudal. Growth rings are clearly evident in most individuals, but become worn smooth with age.
+
+ 
+The plastron (bottom shell) is large and thick along the edges. The gulars (frontmost pair of plastron scutes) do not protrude much past the front of the carapace. The plastron of a male is deeply indented, and the anal scutes (rearmost pair of plastron scutes) may be used to sex the animal while the color pattern varies by region.
+
+The head is relatively small with a squared-off profile and flat on top, longer than it is wide. The eye is large with a brown, almost black iris, and rarely any sclera visible around it. The upper jaw is slightly hooked, and the upper jaw is notched in the front middle. About 15 to 20 'teeth' or fine grooves occur on each side of each jaw. A nearly circular tympanum is located behind and below the eye and is covered with a dark scale. The scales of the head are generally smallish and irregular, becoming small and pebbly on the neck. Many of the scales are colored pale yellow to brick red, especially those on the top of the head, above the tympanum, around the nostrils, on the lower jaw, and on the sides of the neck. Males are usually slightly more colorful than females, and colors vary by region.
+The limbs are generally cylindrical with five claws on the fore limbs and four on the hind, but no visible toes. The fore limbs are slightly flattened and the front surface is covered with large scales, mostly with the same color as the head. They are not as large or protrusive as they are in more primitive species such as the African spurred tortoise (Geochelone sulcata). The tail is muscular, varies in length and overall shape by sex, and lacks any sort of claw on the tip.Average adult sizes vary by region and sex, and 'giants' are often encountered. Red-footed tortoises average 30–35 cm (12–14 in) with males slightly larger overall. Tortoises up to 45 cm (18 in) are fairly common and over 50 cm (20 in) are occasionally discovered. The largest known specimen, from Paraguay, was 60 cm (24 in) long, and weighed over 28 kg (62 lb). It is unknown if the 'giants' represent diet availability, genetic issues, longevity, or other possibilities.Hatchling and young red-footed tortoises have much rounder and flatter carapaces that start off as mostly pale yellow to brown. New growth adds dark rings around the pale center of each scute. The marginals of very young tortoises are serrated, especially over the hind limbs. This probably aids in both camouflage against the leaf litter and in making the small animals harder to eat. Young tortoises are generally more colorful overall.
+Males are slightly larger and more colorful overall. The carapace of a  male from north of the Amazon basin shows a 'wasp waist', or constrictions along the sides. The male's plastron is deeply indented to help with positioning during mating. The male's tail is long and muscular, generally carried along a side while the female's tail is short and conical.
+The anal scutes vary to allow the male's tail more mobility and allows more protection for the female's hind end. The gap between the points of the anal scales and the marginals is wider and the anal scutes form a broader angle- almost a straight line across- in males to allow the tail to move laterally. The angle is more closed (to about a 90° angle) and the points are closer to the marginals in females.
+
+
+== Distribution and habitat ==
+
+Red-footed tortoises range from southeastern Panama to Venezuela, Guyana, Suriname, and Guiana in the north; south along the Andes to the west in Colombia, Ecuador, Peru, and Bolivia; east to Brazil, and along the southern range in Bolivia, Paraguay, and possibly northern Argentina. They are not evenly distributed within their range. For example, they are not often found in central Brazil or in heavily forested areas in general, and have only documented in Peru since 1985. Accurate range information is complicated by the sheer size of the range, political and geographic barriers, and confusion about where many specimens were collected.They are also found on several Caribbean Islands, although it is not always clear if they are native or brought by humans. Many of the colonies seem to have been established in the 17th century as food supplies or as pets. They are found on the former Netherlands Antilles, Trinidad, Tobago, Grenada, Barbados, St. Vincent, the Grenadines, Santa Lucia, Martinique, Dominica, Guadalupe, the Leeward Islands, the Virgin Islands, and Puerto Rico.
+
+The preferred habitat of the red-footed tortoise varies somewhat by region, but generally includes fairly consistent seasonal temperatures near 30 °C (86 °F) that rarely get lower than 20 °C (68 °F) or over 35 °C (95 °F), generally with high humidity and plenty of rainfall, although some of the areas can get quite dry. Most of the range experiences cooler wet seasons (April to August) and warmer dry seasons (September to March), but some parts of the southern range have occasional cold snaps. Red-footed tortoises are often found in or near transitional areas between forest and savannah, such as forest clearings, wood edges, or along waterways.
+
+
+=== Regional variations ===
+Various authors have divided the red-footed tortoise into different groups by anatomy and geography. Peter Pritchard recognized seven types, but DNA research has identified five genotypes.The most obvious differences are between the groups found north or south of the Amazon basin. The 'northern' variants all look very much like the holotype and are distinguished primarily by shell, head, and limb coloration. The variants south of the Amazon are generally both larger and smaller than the holotype, have a very different plastral pattern, and have an enlarged scale or 'spur' on the inside of the fore limb elbow.
+
+
+==== Northeastern variant ====
+This is the holotype of the species. Head and limb colors are generally light orange to red. Plastrons are mostly pale yellow. They range in the Guiana Shield- Venezuela, Guyana, Suriname, Guiana, and northern Brazil.
+
+
+==== Northwestern variant ====
+They are similar to the northeastern variant, but their carapace base color is grey, dark brown, or coffee rather than black. Their pale plastrons have central dark areas resembling an exclamation point. Their heads and limbs are generally pale yellow to orange. The average size is slightly smaller than usual- 30–35 cm. They are found in southeast Panama and Colombia.
+
+
+==== Northern variant ====
+These also are similar to the northeastern variant, with head and limb colors generally pale yellow to light orange, rarely red, and their heads and limbs are often slightly different colors. The average size is slightly smaller than usual- 30–35 cm. They are found in Colombia, Ecuador, and Peru.
+
+
+==== Southern variant ====
+ 
+The southern variants' carapaces are often not quite black to dark brown, sometimes with light grey or whitish between the scutes. Their plastrons are mostly dark in a symmetrical mottled pattern. Size tends to be larger on average then northeastern variants, with the largest individuals found in this area. Fore limbs feature a slightly enlarged scale on the side of the 'elbow'. Adult males do not have the constricted waist, and females average a bit larger than the males. They are seen in the Gran Chaco - Bolivia, Paraguay, and northern Argentina.
+
+
+==== Eastern variant ====
+Carapaces of the eastern variants are often light grey or whitish between the scutes. Their plastrons are mostly dark in a symmetrical mottled pattern. Size tends to be smaller on average than northeastern variants, also reaching sexual maturity at a smaller size. Fore limbs feature a slightly enlarged scale on the side of the 'elbow'. Their heads and limbs are either yellowish or red, ranging to brilliant cherry-red. They are located in east to southeast Brazil. The red-headed type of this variant is often called a 'cherry-head' in the pet trade.
+
+
+== Population features ==
+Little information is available about population density or sex ratios. Many specimens are recorded from near research stations and cities, but that is almost certainly more due to the ease of finding them there than higher localized populations. They are considered one of the most common turtle species in many localities. When a dam was being built in the Edo region of Venezuela, several hundreds of the red- and yellow-footed tortoises were captured for relocation. Large numbers are also found in markets, confiscated at airports, etc. However, very few records exist from Peru, Ecuador, Argentina, and central Brazil. In the Guiana Shield region, islands of higher populations and stretches where few have been located are seen.Counting tortoises that are often well-hidden, dug in, deep in burrows, etc. is difficult. Trained dogs discover many that otherwise might not be found. One study showed a nearly balanced mix of 1.32 males per female, and 1.05 red-footed tortoises per hectare (2.4 acres) on the island, which may be an underestimate due to the difficulty in finding the tortoises.
+
+
+== Evolutionary history and fossil record ==
+The genus Chelonoidis has two main subcategories based on appearance and habitat- the C. carbonarius and the C. chilensis groups. The C. carbonarius group has the closely related red- and yellow-footed tortoises that clearly share a common ancestor. The C. chilensis group features the Chaco tortoise (C. chilensis) and Galápagos tortoise (C. niger), which share similar habitats and a basic appearance, but otherwise do not seem to be closely related. The relationship between the groups is unclear.Several theories are offered to explain the relatively small number of tortoise species in South America and the relationship between them, but the fossil record is not very complete. One long-held theory is that they came from Asia using the land bridge, then spread down through North America and shared ancestors with the gopher tortoises (Gopherus species). Another holds Geochelone ancestors floated over from central Africa, taking advantage of their ability to float, resist salt water, and go without food for extended periods.
+DNA studies suggest that the carbonarius group may be related to the African hingeback tortoises (Kinixys species). This suggests that they might have come from Gondwana before it separated into Africa and South America some 130 million years ago.  One ancestral form from about 5mya, Chelonoidis hesterna (Auffenberg 1971), is thought to have lived in wet forests and split into two species in the Miocene with the yellow-footed tortoises remaining in the deep forest and the red-footeds colonizing the edges of the forests and the emerging savannahs. As the climate and topography changed, groups of red-footed tortoises became physically separated and genetically isolated.
+
+
+== Ecology and behavior ==
+The red-footed tortoise's climate in the northern part of the range changes little day to day  and rarely gets too hot for them, so the tortoises do not need to practice any form of dormancy and can often forage all day long. The tortoises in Moskovitz's study area were most active after 3:00pm while many species from warmer climes would be most active in the morning and evening. Tortoises from the southern parts of the range experience much hotter, colder, and drier conditions than most of the range and aestivate when food becomes scarce. They may aestivate or brumate when the temperatures are low enough.Most species of tortoise spend much of their day inactive, and red-footed tortoises generally spend over 50% of the daylight hours at rest. They may rest for even longer after a large meal, with five- to ten-day stretches being common. One large specimen seems to have stayed in the same position for over a month. Resting tortoises barely move, allowing leaf litter to accumulate on them, and termites have built tunnels on the carapaces of resting red-footed tortoises.
+
+ They seek shelter in places that offer thermoregulation and protection from predators. Treefalls are a favored site, as are debris piles, burrows (especially those of the armadillo (Dasypodidae family) and agouti (Dasyprocta species)), hollow logs, holes, and heavy vegetation cover. They generally try to find tight-fitting resting places, and will occasionally 'wedge' themselves between roots and trunks but remain otherwise exposed. Burrows and holes are often flooded and the tortoises will rest in the water and mud with just their nostrils and eyes exposed. In warmer weather, they press up against moister, cooler surfaces in shelter areas. The tortoises show personal preferences with many individuals always seeking out a specific type of shelter.Shelters are often communal with as many tortoises as can fit in the space. Good shelters are so important, and visibility is so poor that the tortoises will leave scent trails that they or others can follow. Some shelters are so heavily used by tortoises that clear trails in the dirt lead to them, though individual tortoises may not return to a given shelter regularly.Besides communal shelters and scent marking, red-footed tortoises also show other signs of semisocial behavior such as lack of aggression at feeding sites, not protecting territory, and group feeding at fruit falls and carrion (although it is not unusual for one tortoise to block access or even try to make off with some of the food). Red-footed tortoises often follow each other, usually a smaller one following a larger and quite often males following males, but all combinations are seen. They have also been observed following apparent scent trails laid by an individual a day or two earlier.
+
+
+=== Predators ===
+Hatchling and young tortoises are at high risk of predation. Tegu lizards (Tupinambis species), ring-tailed coatis (Nasua nasua), and introduced rats and mongooses attack nests and eggs. Many predators take the young tortoises, including large lizards, snakes, crocodilians, and even large turtles; predatory birds such as the curassow (Crax species), guan (Penelope species), rails, cuckoos, and falcons; and mammals such as cats (Felidae species), opossums, foxes, peccaries, and feral dogs.Other than humans, the main predators of the adult tortoises are jaguars (Panthera onca). Red-footed and yellow-footed tortoises seem to be a significant food source for jaguars in some parts of their respective ranges, such as Manú National Park in Peru. Jaguars bite at the carapace and work at cracking or prying it apart to extract the soft tissues. Many tortoises show toothmarks from attacks that they survived, often on the hind end when they were otherwise protected in a burrow or shelter.
+
+
+=== Diet ===
+Discussing the diet of the red-footed tortoise is difficult due to the wide variety of foods it eats, the variety and seasonal availability of plants available across the extensive range, interpreting what field reports are trying to describe, and because studying fecal pellets gives very different results than what the animals are observed eating.Forest-dwelling tortoises in the Chelonoidis, Indotestudo, Manouria, and Kinixys genera are omnivores with upper and lower intestines about the same length, while herbivorous genera such as Gopherus and Testudo have longer large intestines to digest fibrous grasses. Most omnivorous tortoises have no other specialized digestive structures, reflecting their generalized, flexible diet.
+
+The bulk of the diet is some sort of fruit or seed pod. Common fruits come from cacti (Opuntia), figs (Ficus), pehen (Acacia aroma), Spondias, Annona, Philodendron, bromeliads, and more. Up to five different kinds of fruits are often found in fecal pellets. The entire fruit is eaten, and the seeds are passed and can germinate, giving red- and yellow-footed tortoises a significant role in seed dispersal. Red-footed tortoises have been observed at the base of fruit trees, apparently waiting for fruit to fall.The rest of the diet includes grasses, leaves, flowers, roots, and shoots from a wide assortment of plants as well as fungi, live invertebrates (such as ants, termites, beetles, butterflies, snails, and worms), carrion, and feces (especially from foxes). Tortoises are often found at carcasses feeding until gorged, and occasionally eat small live animals such as snakes and rodents. Pebbles and sand are also often found in fecal pellets.
+The diet changes based on season and availability. In the wet season it may be roughly 70% fruit, 25% fresh leaves and shoots, and the rest being fungi and animal food. The dry season sees 40% fruits, 23% flowers, 16% fresh leaves and shoots, and the rest fungi, moss, and animal food.Omnivorous tortoises seek out foods high in calcium even if other foods are more readily available, and  even eat mineral-rich soil if they cannot get adequate calcium in the diet.
+
+
+=== Movement ===
+Red-foot tortoises forage over areas ranging from 0.63 to 117.5 hectares (1.6 to 290.3 acres) usually making a 'spiderweb' pattern centered on a good hide or a recent fruit fall. They generally move methodically  around 5 to 20 m/hr (5.5-22 yd/hr), but can raise up on their long legs and move up to 100 m/hr (109 yd/hr) when they want. While they generally forage in zig-zag or looping patterns, they sometimes move 100 m (110 yd) or more in fairly straight lines, often at a rapid pace. They show a marked preference for moving under medium to dense vegetation cover.
+
+
+=== Lifecycle ===
+All turtles and tortoises start as eggs. Red-footed tortoise eggs are roughly spherical and average around 5.0 by 4.2 cm (2.0 by 1.7 in) and weigh 50 g (1.8 oz) with two to seven eggs in a clutch, although the same females may lay multiple clutches near each other. The incubation period is 105–202 days, with 150 being typical.Hatchlings use an egg tooth to open the egg. They stay in the egg or nest for several days. Hatchling shells are bent almost in half in the egg and take some time to straighten out. The 3.6 by 6.3 cm (1.4 by 2.5 in) hatchling's carapace is flat, somewhat creased from being folded in the egg, and has serrated sides. Little is known of the daily activities or diet of hatchling wild tortoises. Subadult tortoises grow quickly to reach breeding sizes- roughly 20 to 25 cm (7.9 to 9.8 in), depending on the average adult size of the regional variant.
+ 
+The peak time for courtship and reproduction is the early wet season in April and May, although it can happen at any time. Courtship noises and possibly scent cues seem to attract other tortoises to 'courting sites' under fruiting  trees such as Genipa. When two tortoises meet about a meter apart, they engage in some specific behaviors to identify the other. The first trigger is head and limb color; the bright red, orange, yellow, or white colors on the dark skin identify the other animal as the proper species. Next, the larger tortoise makes jerky side-to-side head movements for two to four seconds. If both tortoises are males, one will either withdraw and retreat, or they may try to ram each other, trying to get their gular scutes under the other one, then pushing them several meters away as quickly as possible. The defeated tortoise is sometimes flipped onto his back in the process. The defeated tortoise will leave the area afterwards. Neither head bobbing nor ritual combat have been observed in tortoises south of the Amazon Basin, possibly due to the lack of yellow-footed tortoises in the area. Males mounting other males, and even females mounting either sex have been witnessed and are thought to show dominance.
+
+If the other tortoise is a female, she will move away and the male will follow, touching her carapace and occasionally sniffing at her cloaca. If the female stops, the male may either wait for her to resume moving or leave. Males make loud 'clucking' sounds during the chase. After trailing, the male mounts the female, his feet planted on the costals of her carapace, rams his anal scutes against her supracaudal, and makes a loud raspy 'bark'. If the female resumes walking, he may fall off and resume trailing. Females sometimes seem to intentionally use low limbs to knock males off. A receptive female  extends her hind legs and lifts her plastron as the male plants himself on his own extended hind legs as he works to align their cloacae for insertion. The tail, scutes, and penis of the tortoise are designed to work around the awkwardness of the shell. The male often leans his head over her head and holds his jaws wide open making calls that get louder. He may bite her, as well, sometimes quite aggressively. The shells can make loud clacking noises during the forceful thrusts. The female walks away after copulation, sometimes knocking the male off her.
+The female begins nesting five to six weeks after mating. Digging the nests is often difficult in hard soil. The female may urinate to soften the soil before using her hind legs to dig a chamber about 10 by 20 cm (3.9 by 7.9 in) in about three and a half hours. Inexperienced females often dig several partial nests, and even experienced females may abandon a nest they are working on and start another. When the nest is ready, she lowers her tail as deep into the nest as she can and deposits an egg every 30 to 120 seconds. She recovers the nest and tamps the soil down. Females get better at digging, covering, and camouflaging nests over time. After it is covered and hidden, she often gets a long drink of water, then finds a shelter and rest. Very rarely, a red-footed tortoise lays eggs on the surface, or within a patch of cacti.As with other tortoises, red-footed tortoises can reproduce most of their lives, although the number of eggs laid and the ratio of successful hatchlings improves as the tortoise matures, then drops off again as the tortoise ages. Because of the difficulty in determining the age of a wild tortoise, few data on longevity exist, although many live for 30 years or more in captivity.
+
+
+== Conservation and relations with humans ==
+The red-foot tortoise is considered vulnerable and is listed in CITES Appendix II, restricting international trade- although this does not offer protection within a country and smuggling still occurs in large numbers. Conservation parks and refuges, captive-breeding farms in natural conditions, and increased captive breeding in other countries has helped, but they are still exported in large numbers (35,565 from 2000 to 2005), mostly as pets and food. The recorded exports do not include smuggling or other losses, which some estimate to be well over twice that number. They are considered especially at risk in Argentina and Colombia, and are considered more at risk than yellow-footed and Chaco tortoises.
+They are widely used as food throughout their ranges, especially where other meats are limited. Their ability to go a long time without eating makes it easy to catch and keeps them fresh for extended periods. The Catholic Church allows tortoises to be eaten on fasting days when most meats are forbidden such as Lent. Tortoise pie (pastel de morrocoy, served in a tortoise shell) is a favorite food for those times, and large numbers of tortoises are exported just for that purpose. Even people living in countries with an abundance of available livestock enjoy wild game, such as tortoises, when possible. Hunting for food is so extensive that Colombia and some other countries import tortoises from neighbors.
+Habitat destruction is another significant threat to the red-footed tortoise, and so many other species. They are also widely collected as local pets and their shells are sold as souvenirs.
+
+
+== Captive care ==
+Red-footed tortoises are popular pet tortoises around the world. They are relatively inexpensive, are a manageable size, have interesting personalities, and are colorful. Pet tortoises should be purchased as captive-bred from a reliable breeder when possible to both help protect wild populations and to avoid internal parasites.Any reptile can carry Salmonella species, so keepers should practice proper hygiene, such as washing their hands after handling the animals or their wastes. Dogs, even well-behaved dogs, often attack or chew on tortoises, so great care must be taken if they are around.
+
+
+=== Housing ===
+All tortoises should be housed outdoors when conditions allow. Outdoor pens should allow space for exercise, secure walls that are at least 1.5 times taller than the tortoise is long, and security from both predators and escape. Shelter and water should always be provided.Indoor housing is generally scaled to the size of the tortoise and must be secure and waterproof for this high-humidity species, as well as offering adequate space. Aquaria and plastic tubs are often used for younger tortoises, while a "tortoise table" (similar to shelf-less bookcase lying on its back), indoor minigreenhouse, or large indoor pen can be used for larger tortoises or groups of tortoises.An indoor habitat should be lined with a substrate such as hardwood mulches (like cypress), coconut coir, soil and sand mixes, or some combination. A hide and water dish are necessary, and live or silk plants also help.
+
+
+=== Environment ===
+Heat, light, and humidity must be kept within proper guidelines for healthy tortoises. Red-footed tortoises are most active at temperatures from 27 to 30 °C (81 to 86 °F). A warmer area of 30 to 31 °C (86 to 88 °F) is recommended, and night temperatures can drop a few degrees lower. High levels of humidity should be available in some part of the habitat.Lighting should be low and diffuse or plenty of shade should be offered. Lights that emit UVB wavelengths are recommended to help the tortoise metabolize calcium correctly and help regulate the pineal gland if the tortoise will be indoors for extended periods.
+
+
+=== Captive diet ===
+Pet tortoises should be allowed to forage in a well-planted outdoor pen whenever possible. The basic diet should consist of a variety of plants, vegetables, and fruits with occasional meat, and be high in calcium and fiber, and low in sugars and fats. Fruits should be kept as whole as possible. Commercial tortoise pellets can be offered along with fresh foods.
+The bulk of the diet should be leafy greens such as turnip or collard greens, dandelion, leafy or curly lettuces, endive, kale, cabbage, edible tree or plant leaves such as mulberry or hibiscus, lettuce mixes, parsley, grape leaves, etc.
+Vegetables and fruits offer variety and other nutrients, but are a smaller part of the captive diet. Good choices would include: cactus pads and fruits, papaya, figs, mango, mushrooms, pumpkin, squash, melon, pineapple, strawberry, cucumber, hays and grasses (such as wheatgrass), corn, peas and beans, carrot, apple, pear, plums, and okra.
+Meats form a very small part of the captive diet, and can include live bugs or invertebrates (especially slugs), baby mice or rats, chicken, egg, organ meat, lean beef, tuna or other 'oily' fish, or cat or dog food.
+Calcium should be supplemented frequently in very small amounts. Other vitamins can be offered in very small amounts as well, but are best provided through a balanced, varied diet.

+The common snapping turtle (Chelydra serpentina) is a species of large freshwater turtle in the family Chelydridae. Its natural range extends from southeastern Canada, southwest to the edge of the Rocky Mountains, as far east as Nova Scotia and Florida. The three species of Chelydra and the larger alligator snapping turtles (genus Macrochelys) are the only extant chelydrids, a family now restricted to the Americas. The common snapping turtle, as its name implies, is the most widespread.The common snapping turtle is noted for its combative disposition when out of the water with its powerful beak-like jaws, and highly mobile head and neck (hence the specific epithet serpentina, meaning "snake-like"). In water, it is likely to flee and hide underwater in sediment. The common snapping turtle has a life-history strategy characterized by high and variable mortality of embryos and hatchlings, delayed sexual maturity, extended adult longevity, and iteroparity (repeated reproductive events) with low reproductive success per reproductive event.Females, and presumably also males, in more northern populations mature later (at 15–20 years) and at a larger size than in more southern populations (about 12 years). Lifespan in the wild is poorly known, but long-term mark-recapture data from Algonquin Park in Ontario, Canada, suggest a maximum age over 100 years.
+
+
+== Anatomy and morphology ==
+
+C. serpentina has a rugged, muscular build with a ridged carapace (upper shell), although ridges tend to be more pronounced in younger individuals. The carapace length in adulthood may be nearly 50 cm (20 in), though 25–47 cm (9.8–18.5 in) is more common. C. serpentina usually weighs 4.5–16 kg (9.9–35.3 lb). Per one study, breeding common snapping turtles were found to average 28.5 cm (11.2 in) in carapace length, 22.5 cm (8.9 in) in plastron length and weigh about 6 kg (13 lb).Males are larger than females, with almost all  weighing in excess of 10 kg (22 lb) being male and quite old, as the species continues to grow throughout life. Any specimen above the aforementioned weights is exceptional, but the heaviest wild specimen caught reportedly weighed 34 kg (75 lb). Snapping turtles kept in captivity can be quite overweight due to overfeeding and have weighed as much as 39 kg (86 lb). In the northern part of its range, the common snapping turtle is often the heaviest native freshwater turtle.
+
+
+== Ecology and life history ==
+Common habitats are shallow ponds or streams. Some may inhabit brackish environments, such as estuaries. These sources of water tend to have an abundance of aquatic vegetation due to the shallow pools. Common snapping turtles sometimes bask—though rarely observed—by floating on the surface with only their carapaces exposed, though in the northern parts of their range, they also readily bask on fallen logs in early spring. In shallow waters, common snapping turtles may lie beneath a muddy bottom with only their heads exposed, stretching their long necks to the surface for an occasional breath. Their nostrils are positioned on the very tip of the snout, effectively functioning as snorkels.Snapping turtles are omnivorous.  Important aquatic scavengers, they are also active hunters that use ambush tactics to prey on anything they can swallow, including many invertebrates, fish, frogs, reptiles (including snakes and smaller turtles), unwary birds, and small mammals. In some areas adult snapping turtles can occasionally be incidentally detrimental to breeding waterfowl, but their effect on such prey as ducklings and goslings is frequently exaggerated. As omnivorous scavengers though, they will also feed on carrion and a surprisingly large amount of aquatic vegetation.
+
+Common snapping turtles have few predators when older, but eggs are subject to predation by crows, American mink, skunks, foxes, and raccoons. As hatchlings and juveniles, most of the same predators will attack them as well as herons (mostly great blue herons), bitterns, hawks, owls, fishers, American bullfrogs, large fish, and snakes. There are records during winter in Canada of hibernating adult common snapping turtles being ambushed and preyed on by northern river otters. Other natural predators which have reportedly preyed on adults include coyotes, American black bears, American alligators and their larger cousins, alligator snapping turtles. Large, old male snapping turtles have very few natural threats due to their formidable size and defenses, and tend to have a very low annual mortality rate.These turtles travel extensively over land to reach new habitats or to lay eggs. Pollution, habitat destruction, food scarcity, overcrowding, and other factors drive snappers to move; it is quite common to find them traveling far from the nearest water source. Experimental data supports the idea that snapping turtles can sense the Earth's magnetic field, which could also be used for such movements (together with a variety of other possible orientation cues).This species mates from April through November, with their peak laying season in June and July. The female can hold sperm for several seasons, using it as necessary. Females travel over land to find sandy soil in which to lay their eggs, often some distance from the water. After digging a hole, the female typically deposits 25 to 80 eggs each year, guiding them into the nest with her hind feet and covering them with sand for incubation and protection.Incubation time is temperature-dependent, ranging from 9 to 18 weeks. One study on the incubation period of the common snapping turtle incubated the eggs at two temperatures: 20 °C (68 °F) and 30 °C (86 °F). The research found that the incubation period at the higher temperature was significantly shorter at approximately 63 days, while at the lower temperature the time was approximately 140 days. In cooler climates, hatchlings overwinter in the nest. The common snapping turtle is remarkably cold-tolerant; radiotelemetry studies have shown some individuals do not hibernate, but remain active under the ice during the winter.Common snapping turtle hatchlings have recently been found to make sounds before nest exit onto the surface, a phenomenon also known from species in the South American genus Podocnemis and the Ouachita map turtle. These sounds are mostly "clicking" noises, but other sounds, including those that sound somewhat like a “creak” or rubbing a finger along a fine-toothed comb, are also sometimes produced.In the northern part of their range snapping turtles do not breathe for more than six months because ice covers their hibernating site. These turtles can get oxygen by pushing their head out of the mud and allowing gas exchange to take place through the membranes of their mouth and throat. This is known as extrapulmonary respiration.If they cannot get enough oxygen through this method they start to utilize anaerobic pathways, burning sugars and fats without the use of oxygen. The metabolic by-products from this process are acidic and create very undesirable side effects by spring, which are known as oxygen debt. Although designated as "least concern" on the IUCN redlist, the species has been designated in the Canadian part of its range as "Special Concern" due to its life history being sensitive to disruption by anthropogenic activity.
+
+
+== Systematics and taxonomy ==
+Currently, no subspecies of the common snapping turtle are recognized. The former Florida subspecies osceola is currently considered a synonym of serpentina, while the other former subspecies Chelydra rossignonii and Chelydra acutirostris are both recognized as full species.
+
+
+== Behavior ==
+In their environment, they are at the top of the food chain, causing them to feel less fear or aggression in some cases. When they encounter a species unfamiliar to them such as humans, in rare instances, they will become curious and survey the situation and even more rarely may bump their nose on a leg of the person standing in the water. Although snapping turtles have fierce dispositions, when they are encountered in the water or a swimmer approaches, they will slip quietly away from any disturbance or may seek shelter under mud or grass nearby.
+
+
+== Relationship with humans ==
+
+
+=== As food ===
+The common snapping turtle is a traditional ingredient in turtle soup; consumption in large quantities, however, can become a health concern due to potential concentration of toxic environmental pollutants in the turtle's flesh.
+
+
+=== Captivity ===
+The common snapping turtle is not an ideal pet. Its neck is very flexible, and a wild turtle can bite its handler even if picked up by the sides of its shell. The claws are as sharp as those of bears and cannot be trimmed as can dog claws. The turtle uses its paws like a bear for hunting and slicing food, while biting it. Despite this, a snapping turtle cannot use its claws for either attacking (its legs have no speed or strength in "swiping" motions) or eating (no opposable thumbs), but only as aids for digging and gripping. Veterinary care is best left to a reptile specialist. A wild common snapping turtle will make a hissing sound when it is threatened or encountered, but they prefer not to provoke confrontations.It is a common misconception that common snapping turtles may be safely picked up by the tail with no harm to the animal; in fact, this has a high chance of injuring the turtle, especially the tail itself and the vertebral column. Lifting the turtle with the hands is difficult and dangerous. Snappers can stretch their necks back across their own carapace and to their hind feet on either side to bite. When they feel stressed, they release a musky odor from behind their legs.
+It may be tempting to rescue a snapping turtle found on a road by getting it to bite a stick and then dragging it out of immediate danger. This action can, however, severely scrape the legs and underside of the turtle and lead to deadly infections in the wounds. The safest way to pick up a common snapping turtle is by grasping the carapace behind the back legs, being careful to not grasp the tail. There is a large gap behind the back legs that allows for easy grasping of the carapace and keeps hands safe from both the beak and claws of the turtle. It can also be picked up with a shovel, from the back, making sure the shovel is square across the bottom of the shell. The easiest way, though, is with a blanket or tarp, picking up the corners with the turtle in the middle.Snapping turtles are raised on some turtle farms in Mainland China.
+
+
+=== In politics ===
+
+The common snapping turtle was the central feature of a famous American political cartoon. Published in 1808 in protest at the Jeffersonian Embargo Act of 1807, the cartoon depicted a snapping turtle, jaws locked fiercely to an American trader who was attempting to carry a barrel of goods onto a British ship. The trader was seen whimsically uttering the words "Oh! this cursed Ograbme" ("embargo" spelled backwards, and also "O, grab me" as the turtle is doing). This piece is widely considered a pioneering work within the genre of the modern political cartoon.In 2006, the common snapping turtle was declared the state reptile of New York by vote of the New York Legislature after being chosen by the state's public elementary school children.
+
+
+=== Reputation ===
+
+While it is widely rumored that common snapping turtles can bite off human fingers or toes, and their powerful jaws are more than capable of doing so, no proven cases have ever been presented for this species, as they use their overall size and strength to deter would-be predators. Common snapping turtles are "quite docile" animals underwater that prefer to avoid confrontations rather than provoke them.In 2002, a study done in the Journal of Evolutionary Biology found that the common snapping turtle (Chelydra serpentina) registered between 208 and 226 Newtons of force when it came to jaw strength. In comparison, the average bite force of a human (molars area) is between 300 and 700 Newtons. Another non-closely related species known as the alligator snapping turtle has been known to bite off fingers, and at least three documented cases are known.
+
+
+== Invasive species ==
+In recent years in Italy, large mature adult C. serpentina turtles have been taken from bodies of water throughout the country. They were most probably introduced by the release of unwanted pets. In March 2011, an individual weighing 20 kg (44 lb) was captured in a canal near Rome; another individual was captured near Rome in September 2012.In Japan, the species was introduced as an exotic pet in the 1960s; it has been recorded as the source of serious bite injuries. In 2004 and 2005, some 1,000 individuals were found in Chiba Prefecture, making up the majority of individuals believed to have been introduced.
+
+
+== Conservation ==
+The species is currently classified as Least Concern by the IUCN, but has declined sufficiently due to pressure from collection for the pet trade and habitat degradation that Canada and several U.S. states have enacted or are proposing stricter conservation measures. In Canada, it is listed as "Special Concern" in the Species at Risk Act in 2011 and is a target species for projects that include surveys, identification of major habitats, investigation and mitigation of threats, and education of the public including landowners. Involved bodies include governmental departments, universities, museums, and citizen science projects.Although Common snapping turtles are listed as a species of least concern, anthropogenic factors still may have major effects on populations. Decades of road mortality may cause severe population decline in common snapping turtle populations present in urbanized wetlands. A study in southwestern Ontario monitored a population near a busy roadway and found a loss of 764 individuals in only 17 years. The population decreased from 941 individuals in 1985 to 177 individuals in 2002. Road mortality may put common snapping turtle populations at risk of extirpation. Exclusion fencing could aid in decreasing population loss.

+The Jamaican boa or yellow snake (Chilabothrus  subflavus; Jamaican Patois: nanka) is a boa species endemic to Jamaica. No subspecies are currently recognized. Like all other boas, it is not venomous.
+
+
+== Description ==
+The Jamaican boa is golden-green around the head and along the anterior section of the body, with black zigzag crossbars, becoming black toward the posterior end of its body. The snake's body is quite long, up to 2 metres (6 feet 7 inches) in total length.
+
+
+== Distribution and habitat ==
+Found in Jamaica cockpit country, including Goat Island. The type locality given is "Jamaica". Moist limestone forests.
+
+
+== Conservation status ==
+The Jamaican boa's natural populations greatly and constantly declined since the late 19th century, mainly because of predation by introduced species (such as mongooses), human persecution, and habitat destruction. In-situ conservation of the Jamaican boa is seriously hindered by the lack of information on demographic and ecological parameters as well as by a poor understanding of the population structure and species distribution in the wild. This species is classified as Vulnerable (VU) on the IUCN Red List of Threatened Species with the following criteria: A2ce (v2.3, 1994). A species is listed as such when the best available evidence indicates that a population decline of 20% is expected within the next ten years or three generations, whichever is the longer, due to a decline in the quality and area of occupancy. It is therefore considered to be facing a high risk of extinction in the wild.

+The chital or cheetal (Axis axis; ), also known as the spotted deer, chital deer, and axis deer, is a deer species  native to the Indian subcontinent. It was first described and given a binomial name by German naturalist Johann Christian Polycarp Erxleben in 1777. A moderate-sized deer, male chital reach 90 cm (35 in) and females 70 cm (28 in) at the shoulder. While males weigh 70–90 kg (150–200 lb), females weigh around 40–60 kg (88–132 lb). It is sexually dimorphic; males are larger than females, and antlers are present only on males. The upper parts are golden to rufous, completely covered in white spots. The abdomen, rump, throat, insides of legs, ears, and tail are all white. The antlers, three-pronged, are nearly 1 m (3 ft 3 in) long.
+
+
+== Etymology ==
+The vernacular name "chital" (pronounced ) comes from cītal (Hindi: चीतल), derived from the Sanskrit word citrala (चित्रल), meaning "variegated" or "spotted". The name of the cheetah has a similar origin. Variations of "chital" include "cheetal" and "cheetul". Other common names for the chital are Indian spotted deer (or simply the spotted deer) and axis deer.
+
+
+== Taxonomy and phylogeny ==
+The chital was first described by Johann Christian Polycarp Erxleben in 1777 as Cervus axis. In 1827, Charles Hamilton Smith placed the chital in its own subgenus Axis under the genus Cervus. Axis was elevated to generic status by Colin P. Groves and Peter Grubb in 1987. The genus Hyelaphus was considered a subgenus of Axis. However, a morphological analysis showed significant differences between Axis and Hyelaphus. A phylogenetic study later that year showed that Hyelaphus is closer to the genus Rusa than Axis. Axis was revealed to be paraphyletic and distant from Hyelaphus in the phylogenetic tree; the chital was found to form a clade with the barasingha (Rucervus duvaucelii) and the Schomburgk's deer (Rucervus schomburgki). The chital was estimated to have genetically diverged from the Rucervus lineage in the Early Pliocene about 5 million years ago. The following cladogram is based on a 2006 phylogenetic study:
+Fossils of extinct Axis species dating to the early to Middle Pliocene were excavated from Iran in the west to Indochina in the east. Remains of the chital were found in the Middle Pleistocene deposits of Thailand along with sun bear, Stegodon, gaur, wild water buffalo and other living and extinct mammals.
+
+
+== Description ==
+
+The chital is a moderately sized deer. Males reach up to 90–100 cm (35–39 in) and females 65–75 cm (26–30 in) at the shoulder; the head-and-body length is around 1.7 m (5 ft 7 in). While immature males weigh 30–75 kg (66–165 lb), the lighter females weigh 25–45 kg (55–99 lb). Mature stags can weigh up to 98–110 kg (216–243 lb).The tail, 20 cm (7.9 in) long, is marked by a dark stripe that stretches along its length. The species is sexually dimorphic; males are larger than females, and antlers are present only on males.The dorsal (upper) parts are golden to rufous, completely covered in white spots. The abdomen, rump, throat, insides of legs, ears, and tail are all white. A conspicuous black stripe runs along the spine (back bone). The chital has well-developed preorbital glands (near the eyes) with stiff hairs. It also has well-developed metatarsal glands and pedal glands located in its hind legs. The preorbital glands, larger in males than in females, are frequently opened in response to certain stimuli.Each of the antlers has three lines on it. The brow tine (the first division in the antler) is roughly perpendicular to the beam (the central stalk of the antler). The antlers, three-pronged, are nearly 1 m (3 ft 3 in) long. Antlers, as in most other cervids, are shed annually. The antlers emerge as soft tissues (known as velvet antlers) and progressively harden into bony structures (known as hard antlers), following mineralisation and blockage of blood vessels in the tissue, from the tip to the base. A study of the mineral composition of the antlers of captive barasinga, chital, and hog deer showed that the antlers of the deer are very similar. The mineral content of the chital's antlers was determined to be (per kg) 6.1 mg (0.094 gr) copper, 8.04 mg (0.1241 gr) cobalt, and 32.14 mg (0.4960 gr) zinc.Hooves measure between 4.1 and 6.1 cm (1.6 and 2.4 in) in length; hooves of the fore legs are longer than those of the hind legs. The toes taper to a point. The dental formula is 0.1.3.33.1.3.3, same as the elk. The milk canine, nearly 1 cm (0.39 in) long, falls off before one year of age, but is not replaced by a permanent tooth as in other cervids. Compared to the hog deer, the chital has a more cursorial build. The antlers and brow tines are longer than those in the hog deer. The pedicles (the bony cores from which antlers arise) are shorter, and the auditory bullae are smaller in the chital. The chital may be confused with the fallow deer. Chital have several white spots, whereas fallow deer usually have white splotches. Fallow also have palmate antlers whereas chital have 3 distinct points on each side. The chital has a prominent white patch on its throat, while the throat of the fallow deer is completely white. The biggest distinction is the dark brown stripe running down the chital's back. The hairs are smooth and flexible.
+
+
+== Distribution and habitat ==
+The chital ranges over 8–30°N in India and through Nepal, Bhutan, Bangladesh, and Sri Lanka. The western limit of its range is eastern Rajasthan and Gujarat. The northern limit is along the Terai belt of the foothills of the Himalaya and from Uttar Pradesh and Uttaranchal through to Nepal, northern West Bengal and Sikkim and then to western Assam and the forested valleys of Bhutan, which are below an elevation of 1,100 m (3,600 ft). The eastern limit of its range is through western Assam to the Sunderbans of West Bengal and Bangladesh. Andaman and Nicobar Islands  and Sri Lanka are the southern limits. Chital occur sporadically in the forested areas throughout the rest of the Indian peninsula. Within Bangladesh, it currently only exists in the Sundarbans and some ecoparks situated around the Bay of Bengal, as it became extinct in the central and north-east of the country.
+
+
+=== Australia ===
+The chital was the first species of deer introduced into Australia in the early 1800s by Dr. John Harris, surgeon to the New South Wales Corps, and he had about 400 of these animals on his property by 1813. These did not survive, and the primary range of the chital is now confined to a few cattle stations in North Queensland near Charters Towers and several feral herds on the NSW north and south coasts. While some of the stock originated from Sri Lanka (Ceylon), the Indian race likely is also represented.
+
+
+=== The United States ===
+In the 1860s, axis deer were introduced to the island of Molokai, Hawaii, as a gift from Hong Kong to King Kamehameha V. The deer were introduced to Lanai, another of the Hawaiian Islands, soon afterward and are now plentiful on both islands. The deer were introduced to Maui island in the 1950s to increase hunting opportunities. Because the deer have no natural predators on the Hawaiian islands, their population is growing 20 to 30% each year, causing serious damage to agriculture and natural areas.Releasing them on the island of Hawaii was planned, as well, but this was abandoned after pressure from scientists over damage to landscapes caused by the deer on other islands. In 2012, deer were spotted on the island of Hawaii; wildlife officials believe people had flown the deer by helicopter and transported them by boat onto the island. In August 2012, a helicopter pilot pleaded guilty to transporting four axis deer from Maui to Hawaii. Hawaiian law now prohibits "the intentional possession or interisland transportation or release of wild or feral deer."In 1932, axis deer were introduced to Texas. In 1988, self-sustaining herds were found in 27 counties, located in Central and South Texas. The deer are most populous on the Edwards Plateau, where the land is similar to that of India.
+
+
+=== Croatia ===
+Chital of unknown origin were introduced to the island of Brijuni in 1911. They also live on Rab Island, and the population on the two islands comprised about 200 individuals as of 2010. Attempts by hunters to introduce the species to the mainland of Croatia were unsuccessful.
+
+
+== Behaviour and ecology ==
+
+Chital are active throughout the day. In the summer, time is spent in rest under shade, and the sun's glare is avoided if the temperature reaches 80 °F (27 °C); activity peaks as dusk approaches. As days grow cooler, foraging begins before sunrise and peaks by early morning. Activity slows down during midday, when the animals rest or loiter about slowly. Foraging recommences by late afternoon and continues till midnight. They fall asleep a few hours before sunrise, typically in the forest which is cooler than the glades. These deer typically move in a single file on specific tracks, with a distance of two to three times their width between them, when on a journey, typically in search of food and water sources. A study in the Gir National Park (Gujarat, India) showed that chital travel the most in summer of all seasons.When cautiously inspecting its vicinity, the chital stands motionless and listens with rapt attention, facing the potential danger, if any. This stance may be adopted by nearby individuals, as well. As an antipredator measure, chital flee in groups (unlike the hog deer that disperse on alarm); sprints are often followed by hiding in dense undergrowth. The running chital has its tail raised, exposing the white underparts. The chital can leap and clear fences as high as 1.5 m (4.9 ft) but prefers to dive under them. It stays within 300 m (980 ft) of cover.A gregarious animal, the chital forms matriarchal herds comprising an adult female and her offspring of the previous and the present year, which may be associated with individuals of any age and either sex, male herds, and herds of juveniles and mothers. Small herds are common, though aggregations of as many as 100 individuals have been observed. Groups are loose and disband frequently, save for the juvenile-mother herd. Herd membership in Texas is typically up to 15; herds can have five to 40 members in India. Studies in the Nallamala Hills (Andhra Pradesh, India) and the Western Ghats (western coast of India) showed seasonal variation in the sex ratio of herds; this was attributed to the tendency of females to isolate themselves ahead of parturition. Similarly, rutting males leave their herds during the mating season, hence altering the herd composition. Large herds are most common in monsoon, observed foraging in the grasslands.Predators of chitals include Indian wolves, Bengal tigers, Asiatic lions, leopards, pythons, dholes, Indian pariah dogs, bears, and crocodiles. Fishing cats, jungle cats, foxes, golden jackals and eagles target juveniles. Males are less vulnerable than females and juveniles.A vocal animal, the chital, akin to the North American elk, gives out bellows and alarm barks. Its calls are, however, not as strong as those of elk or red deer; they are mainly coarse bellows or loud growls. Bellowing coincides with rutting. Dominant males guarding females in oestrus make high-pitched growls at less powerful males. Males may moan during aggressive displays or while resting. Chital, mainly females and juveniles, bark persistently when alarmed or if they encounter a predator. Fawns in search of their mother often squeal. The chital can respond to the alarm calls of several animals, such as the common myna and langurs.Marking behaviour is pronounced in males. Males have well-developed preorbital glands (near the eyes). They stand on their hind legs to reach tall branches and rub the open preorbital glands to deposit their scent there. This posture is also used while foraging. Urine marking is also observed; the smell of urine is typically stronger than that of the deposited scent. Sparring between males begins with the larger male displaying his dominance before the other; this display consists of hissing heading away from the other male with the tail facing him, the nose pointing to the ground, the ears down, the antlers upright, and the upper lip raised. The fur often bristles during the display. The male approaches the other in a slow gait. Males with velvet antlers may hunch over instead of standing erect as the males with hard antlers. The opponents then interlock their horns and push against each other, with the smaller male producing a sound at times which is louder than that produced by sambar deer, but not as much as the barasinga's. The fight terminates with the males stepping backward, or simply leaving and foraging. Fights are not generally serious.Individuals may occasionally bite one another. Common mynas are often attracted to the chital. An interesting relationship has been observed between herds of chital and troops of the northern plains grey langurs, a widespread South Asian monkey. Chital benefit from the langurs' eyesight and ability to post a lookout from trees, while the langur benefit from the chital's strong sense of smell, both of which help keep a check on potential danger. The chital also benefit from fruits dropped by langurs from trees such as Terminalia bellirica and Phyllanthus emblica. The chital has been observed foraging with sambar deer in the Western Ghats.
+
+
+=== Diet ===
+
+Grazers as well as browsers, the chital mainly feed on grasses throughout the year. They prefer young shoots, in the absence of which, tall and coarse grasses are nibbled off at the tips. Browse forms a major portion of the diet only in the winter-October to January-when the grasses, tall or dried up, are no longer palatable. Browse includes herbs, shrubs, foliage, fruits, and forbs; Moghania species are often preferred while browsing. Fruits eaten by chital in the Kanha National Park (Madhya Pradesh, India) include those of Ficus species from January to May, Cordia myxa from May to June, and Syzygium cumini from June to July. Individuals tend to group together and forage while moving slowly. Chital are generally silent when grazing together. Males often stand on their hindlegs to reach tall branches. Water holes are visited nearly twice daily, with great caution. In the Kanha National Park, mineral licks rich in calcium and phosphorus pentoxide were scraped at by the incisors. Chital also gnaw bones and fallen antlers for their minerals. Males in velvet indulge in such osteophagia to a greater extent. Chital in the Sunderbans may be omnivores; remains of red crabs have been found in the rumen of individuals.
+
+
+=== Reproduction ===
+
+Breeding takes place throughout the year, with peaks that vary geographically. Sperm is produced year-round, though testosterone levels register a fall during the development of the antlers. Females have regular oestrus cycles, each lasting three weeks. The female can conceive again two weeks to four months after the birth. Males sporting hard antlers are dominant over those in velvet or those without antlers, irrespective of their size. Courtship is based on tending bonds. A rutting male fasts during the mating season and follows and guards a female in oestrus. The pair does several bouts of chasing and mutual licking before copulation.The newborn is hidden for a week after birth, a period much shorter than most other deer. The mother-fawn bond is not very strong, as the two get separated often, though they can reunite easily as the herds are cohesive. If the fawn dies, the mother can breed once again so as to give birth twice that year. The males continue their growth till seven to eight years. The average lifespan in captivity is nearly 22 years. The longevity in the wild, however, is merely five to ten years.The chital is found in large numbers in dense deciduous or semievergreen forests and open grasslands. The highest numbers of chital are found in the forests of India, where they feed upon tall grass and shrubs. Chital have been also spotted in Phibsoo Wildlife Sanctuary in Bhutan, which has the only remaining natural sal (Shorea robusta) forest in the country. They do not occur at high altitudes, where they are usually replaced by other species such as the sambar deer. They also prefer heavy forest cover for shade and avoid direct sunlight.
+
+
+== Conservation status ==
+The chital is listed on the IUCN Red List as least concern "because it occurs over a very wide range within which there are many large populations". Currently, no range-wide threats to chitals are present, and they live in many protected areas. However, population densities are below ecological carrying capacity in many places due to hunting and competition with domestic livestock. Hunting for the deer's meat has caused substantial declines and local extinctions. The axis deer is protected under Schedule III of the Indian Wildlife Protection Act (1972) and under the Wildlife (Preservation) (Amendment) Act, 1974 of Bangladesh. Two primary reasons for its good conservation status are its legal protection as a species and a network of functioning protected areas.The chital has been introduced to the Andaman Islands, Argentina, Australia, Brazil, Chile, Mexico, Paraguay, Uruguay, Alabama, Point Reyes National Seashore in California, Florida, Hawaii, Mississippi, and Texas in the United States, and the Veliki Brijun Island in the Brijuni Archipelago of the Istrian Peninsula in Croatia.With effect from 2 August 2022, the European Union added the chital to the list of invasive alien species and banned its import into the EU.

+The pygmy hippopotamus or pygmy hippo (Choeropsis liberiensis) is a small hippopotamid which is native to the forests and swamps of West Africa, primarily in Liberia, with small populations in Sierra Leone, Guinea, and Ivory Coast. It has been extirpated from Nigeria.The pygmy hippo is reclusive and nocturnal. It is one of only two extant species in the family Hippopotamidae, the other being its much larger relative, the common hippopotamus (Hippopotamus amphibius) or Nile hippopotamus. The pygmy hippopotamus displays many terrestrial adaptations, but like the hippo, it is semiaquatic and relies on water to keep its skin moist and its body temperature cool. Behaviors such as mating and giving birth may occur in water or on land. The pygmy hippo is herbivorous, feeding on ferns, broad-leaved plants, grasses, and fruits it finds in the forests.
+A rare nocturnal forest creature, the pygmy hippopotamus is a difficult animal to study in the wild.
+Pygmy hippos were unknown outside West Africa until the 19th century. Introduced to zoos in the early 20th century, they breed well in captivity and the vast majority of research is derived from zoo specimens. The survival of the species in captivity is more assured than in the wild; in a 2015 assessment, the International Union for Conservation of Nature estimated that fewer than 2,500 pygmy hippos remain in the wild.Pygmy hippos are primarily threatened by loss of habitat, as forests are logged and converted to farm land, and are also vulnerable to poaching, hunting for bushmeat, natural predators, and war. Pygmy hippos are among the species illegally hunted for food in Liberia.
+
+
+== Taxonomy and origins ==
+Nomenclature of the pygmy hippopotamus reflects that of the hippopotamus; the plural form is pygmy hippopotamuses or pygmy hippopotami. A male pygmy hippopotamus is known as a bull, a female as a cow, and a baby as a calf.  A group of hippopotami is known as a herd or a bloat.
+
+The pygmy hippopotamus is a member of the family Hippopotamidae where it is classified as a member of the genus Choeropsis ("resembling a hog"). Members of Hippopotamidae are sometimes known as hippopotamids. Sometimes the sub-family Hippopotaminae is used. Further, some taxonomists group hippopotami and anthracotheres in the superfamily Anthracotheroidea or Hippopotamoidea.
+A sister species of the pygmy hippopotamus may have been the little-studied Malagasy pygmy hippopotamus (Hippopotamus madagascariensis), one of three recently extinct species from Madagascar. H. madagascariensis was the same size as C. liberiensis and shared its terrestrial behavior, inhabiting the forested highlands of Madagascar, rather than open rivers. It is believed to have gone extinct within the last 500 years.The taxonomy of the genus of the pygmy hippopotamus has changed as understanding of the animal has developed. Samuel G. Morton initially classified the animal as Hippopotamus minor, but later determined it was distinct enough to warrant its own genus, and labeled it Choeropsis. In 1977, Shirley C. Coryndon proposed that the pygmy hippopotamus was closely related to Hexaprotodon, a genus that consisted of prehistoric hippos mostly native to Asia.This assertion was widely accepted, until Boisserie asserted in 2005 that the pygmy hippopotamus was not a member of Hexaprotodon, after a thorough examination of the phylogeny of Hippopotamidae. He suggested instead that the pygmy hippopotamus was a distinct genus, and returned the animal to Choeropsis.  ITIS verifies Hexaprotodon liberiensis as the valid scientific name.  All agree that the modern pygmy hippopotamus, be it H. liberiensis or C. liberiensis, is the only extant member of its genus. The American Society of Mammalogists moved it back to Choeropsis in 2021, a move supported by the IUCN.
+
+
+=== Nigerian subspecies ===
+A distinct subspecies of pygmy hippopotamus existed in Nigeria until at least the 20th century, though the validity of this has been questioned. The existence of the subspecies, makes Choeropsis liberiensis liberiensis (or Hexaprotodon liberiensis liberiensis under the old classification) the full trinomial nomenclature for the Liberian pygmy hippopotamus. The Nigerian pygmy hippopotamus was never studied in the wild and never captured. All research and all zoo specimens are the Liberian subspecies. The Nigerian subspecies is classified as C. liberiensis heslopi.The Nigerian pygmy hippopotamus ranged in the Niger River Delta, especially near Port Harcourt, but no reliable reports exist after the collection of the museum specimens secured by I. R. P. Heslop, a British colonial officer, in the early 1940s. It is probably extinct. The subspecies is separated by over 1,800 km (1,100 mi) and the Dahomey Gap, a region of savanna that divides the forest regions of West Africa. The subspecies is named after I. R. P. Heslop, who claimed in 1945 to have shot a pygmy hippo in the Niger Delta region and collected several skulls. He estimated that perhaps no more than 30 pygmy hippos remained in the region.Heslop reportedly sent four pygmy hippopotamus skulls he collected to the British Museum of Natural History in London. These specimens were not subjected to taxonomic evaluation, however, until 1969 when G. B. Corbet classified the skulls as belonging to a separate subspecies based on consistent variations in the proportions of the skulls. The Nigerian pygmy hippos were seen or shot in Rivers State, Imo State and Bayelsa State, Nigeria. While some local populations are aware that the species once existed, its history in the region is poorly documented.
+
+
+=== Evolution ===
+
+The evolution of the pygmy hippopotamus is most often studied in the context of its larger cousin. Both species were long believed to be most closely related to the family Suidae (pigs and hogs) or Tayassuidae (peccaries), but research within the last 10 years has determined that pygmy hippos and hippos are most closely related to cetaceans (whales and dolphins). Hippos and whales shared a common semi-aquatic ancestor that branched off from other artiodactyls around 60 mya.This hypothesized ancestor likely split into two branches about six million years later. One branch would evolve into cetaceans, the other branch became the anthracotheres, a large family of four-legged beasts, whose earliest member, from the Late Eocene, would have resembled narrow hippopotami with comparatively small and thin heads.Hippopotamids are deeply nested within the family Anthracotheriidae. The oldest known hippopotamid is the genus Kenyapotamus, which lived in Africa from 16 to 8 mya. Kenyapotamus is known only through fragmentary fossils, but was similar in size to C. liberiensis. The Hippopotamidae are believed to have evolved in Africa, and while at one point the species spread across Asia and Europe, no hippopotami have ever been discovered in the Americas. Starting 7.5 to 1.8 mya the Archaeopotamus, likely ancestors to the genus Hippopotamus and Hexaprotodon, lived in Africa and the Middle East.While the fossil record of hippos is still poorly understood, the lineages of the two modern genera, Hippopotamus and Choeropsis, may have diverged as far back as 8 mya. The ancestral form of the pygmy hippopotamus may be the genus Saotherium. Saotherium and Choeropsis are significantly more basal than Hippopotamus and Hexaprotodon, and thus more closely resemble the ancestral species of hippos.
+
+
+=== Extinct pygmy and dwarf hippos ===
+Several species of small hippopotamids have also become extinct in the Mediterranean in the late Pleistocene or early Holocene. Though these species are sometimes known as "pygmy hippopotami" they are not believed to be closely related to C. liberiensis. These include the Cretan dwarf hippopotamus (Hippopotamus creutzburgi), the Sicilian hippopotamus (Hippopotamus pentlandi), the Maltese hippopotamus (Hippopotamus melitensis) and the Cyprus dwarf hippopotamus (Hippopotamus minor).These species, though comparable in size to the pygmy hippopotamus, are considered dwarf hippopotamuses, rather than pygmies. They are likely descended from a full-sized species of European hippopotamus, and reached their small size through the evolutionary process of insular dwarfism which is common on islands; the ancestors of pygmy hippopotami were also small and thus there was never a dwarfing process. There were also several species of pygmy hippo on the island of Madagascar (see Malagasy hippopotamus).
+
+
+== Description ==
+
+Pygmy hippos share the same general form as a hippopotamus. They have a graviportal skeleton, with four stubby legs and four toes on each foot, supporting a portly frame. Yet, the pygmy is only half as tall as the hippopotamus and weighs less than 1/4 as much as its larger cousin. Adult pygmy hippos stand about 75–100 cm (2.46–3.28 ft) high at the shoulder, are 150–175 cm (4.92–5.74 ft) in length and weigh 180–275 kg (397–606 lb). Their lifespan in captivity ranges from 30 to 55 years, though it is unlikely that they live this long in the wild.The skin is greenish-black or brown, shading to a creamy gray on the lower body. Their skin is very similar to the common hippo's, with a thin epidermis over a dermis that is several centimeters thick. Pygmy hippos have the same unusual secretion as common hippos, that gives a pinkish tinge to their bodies, and is sometimes described as "blood sweat" though the secretion is neither sweat nor blood. This substance, hipposudoric acid, is believed to have antiseptic and sunscreening properties. The skin of hippos dries out quickly and cracks, which is why both species spend so much time in water.The skeleton of C. liberiensis is more gracile than that of the common hippopotamus, meaning their bones are proportionally thinner. The common hippo's spine is parallel with the ground; the pygmy hippo's back slopes forward, a likely adaptation to pass more easily through dense forest vegetation. Proportionally, the pygmy hippo's legs and neck are longer and its head smaller.
+
+The orbits and nostrils of a pygmy hippo are much less pronounced, an adaptation from spending less time in deep water (where pronounced orbits and nostrils help the common hippo breathe and see). The feet of pygmy hippos are narrower, but the toes are more spread out and have less webbing, to assist in walking on the forest floor.Despite adaptations to a more terrestrial life than the common hippopotamus, pygmy hippos are still more aquatic than all other even-toed ungulates. The ears and nostrils of pygmy hippos have strong muscular valves to aid submerging underwater, and the skin physiology is dependent on the availability of water.
+
+
+== Behavior ==
+
+The behavior of the pygmy hippo differs from the common hippo in many ways. Much of its behavior is more similar to that of a tapir, though this is an effect of convergent evolution. While the common hippopotamus is gregarious, pygmy hippos live either alone or in small groups, typically a mated pair or a mother and calf. Pygmy hippos tend to ignore each other rather than fight when they meet. Field studies have estimated that male pygmy hippos range over 1.85 km2 (460 acres), while the range of a female is 0.4 to 0.6 km2 (100–150 acres).Pygmy hippos spend most of the day hidden in rivers. They will rest in the same spot for several days in a row, before moving to a new spot. At least some pygmy hippos make use of dens or burrows that form in river banks. It is unknown if the pygmy hippos help create these dens, or how common it is to use them. Though a pygmy hippo has never been observed burrowing, other artiodactyls, such as warthogs, are burrowers.
+
+
+=== Diet ===
+Like the common hippopotamus, the pygmy hippo emerges from the water at dusk to feed. It relies on game trails to travel through dense forest vegetation. It marks trails by vigorously waving its tail while defecating to further spread its feces. The pygmy hippo spends about six hours a day foraging for food.
+
+Pygmy hippos are herbivorous. They do not eat aquatic vegetation to a significant extent and rarely eat grass because it is uncommon in the thick forests they inhabit. The bulk of a pygmy hippo's diet consists of ferns, broad-leaved plants and fruits that have fallen to the forest floor. The wide variety of plants pygmy hippos have been observed eating suggests that they will eat any plants available. This diet is of higher quality than that of the common hippopotamus.
+
+
+=== Reproduction ===
+
+A study of breeding behavior in the wild has never been conducted; the artificial conditions of captivity may cause the observed behavior of pygmy hippos in zoos to differ from natural conditions. Sexual maturity for the pygmy hippopotamus occurs between three and five years of age. The youngest reported age for giving birth is a pygmy hippo in the Zoo Basel, Switzerland which bore a calf at three years and three months. The oestrus cycle of a female pygmy hippo lasts an average of 35.5 days, with the oestrus itself lasting between 24 and 48 hours.Pygmy hippos consort for mating, but the duration of the relationship is unknown. In zoos they breed as monogamous pairs. Copulation can take place on land or in the water, and a pair will mate one to four times during an oestrus period. In captivity, pygmy hippos have been conceived and born in all months of the year. The gestation period ranges from 190 to 210 days, and usually a single young is born, though twins are known to occur.The common hippopotamus gives birth and mates only in the water, but pygmy hippos mate and give birth on both land and water. Young pygmy hippos can swim almost immediately. At birth, pygmy hippos weigh 4.5–6.2 kg (9.9–13.7 lb) with males weighing about 0.25 kg (0.55 lb) more than females. Pygmy hippos are fully weaned between six and eight months of age; before weaning they do not accompany their mother when she leaves the water to forage, but instead hide in the water by themselves. The mother returns to the hiding spot about three times a day and calls out for the calf to suckle. Suckling occurs with the mother lying on her side.

+
+== Conservation ==
+
+The greatest threat to the remaining pygmy hippopotamus population in the wild is loss of habitat. The forests in which pygmy hippos live have been subject to logging, settling and conversion to agriculture, with little efforts made to make logging sustainable. As forests shrink, the populations become more fragmented, leading to less genetic diversity in the potential mating pool.Pygmy hippos are among the species illegally hunted for food in Liberia. Their meat is said to be of excellent quality, like that of a wild boar; unlike those of the common hippo, the pygmy hippo's teeth have no value. The effects of West Africa's civil strife on the pygmy hippopotamus are unknown, but unlikely to be positive. The pygmy hippopotamus can be killed by leopards, pythons and crocodiles. How often this occurs is unknown.C. liberiensis was identified as one of the top 10 "focal species" in 2007 by the Evolutionarily Distinct and Globally Endangered (EDGE) project. Some populations inhabit protected areas, such as the Gola Forest Reserve in Sierra Leone.Basel Zoo in Switzerland holds the international studbook and coordinates the entire captive pygmy hippo population that freely breeds in zoos around the world. Between 1970 and 1991 the population of pygmy hippos born in captivity more than doubled. The survival of the species in zoos is more certain than the survival of the species in the wild. In captivity, the pygmy hippo lives from 42 to 55 years, longer than in the wild. Since 1919, only 41 percent of pygmy hippos born in zoos have been male.
+
+
+== History and folklore ==
+
+While the common hippopotamus was known to Europeans since classical antiquity, the pygmy hippopotamus was unknown outside its range in West Africa until the 19th century. Due to their nocturnal, forested existence, they were poorly known within their range as well. In Liberia the animal was traditionally known as a water cow.Early field reports of the animal misidentified it as a wild hog. Several skulls of the species were sent to the American natural scientist Samuel G. Morton, during his residency in Monrovia, Liberia. Morton first described the species in 1843. The first complete specimens were collected as part of a comprehensive investigation of Liberian fauna in the 1870s and 1880s by Dr. Johann Büttikofer. The specimens were taken to the Natural History Museum in Leiden, The Netherlands.The first pygmy hippo was brought to Europe in 1873 after being captured in Sierra Leone by a member of the British Colonial Service but died shortly after arrival. Pygmy hippos were successfully introduced to Europe in 1911. They were first shipped to Germany and then to the Bronx Zoo in New York City where they also thrived.In 1927, Harvey Firestone of Firestone Tires presented Billy the pygmy hippo to U.S. President Calvin Coolidge. Coolidge donated Billy to the National Zoo in Washington, D.C. According to the zoo, Billy is a common ancestor to most pygmy hippos in U.S. zoos today.Several folktales have been collected about the pygmy hippopotamus. One tale says that pygmy hippos carry a shining diamond in their mouths to help travel through thick forests at night; by day the pygmy hippo has a secret hiding place for the diamond, but if a hunter catches a pygmy hippo at night the diamond can be taken. Villagers sometimes believed that baby pygmy hippos do not nurse but rather lick secretions off the skin of the mother.

+The golden pheasant (Chrysolophus pictus), also known as the Chinese pheasant, and rainbow pheasant, is a gamebird of the order Galliformes (gallinaceous birds) and the family Phasianidae (pheasants). The genus name is from Ancient Greek khrusolophos, "with golden crest", and pictus is Latin for "painted" from pingere, "to paint".
+
+
+== Description ==
+It is native to forests in mountainous areas of western China, but feral populations have been established in the United Kingdom, Canada, the United States, Mexico, Colombia, Peru, Bolivia, Chile, Argentina, Uruguay, the Falkland Islands, Germany, Belgium, the Netherlands, France, Ireland, Australia and New Zealand. In England they may be found in East Anglia in the dense forest landscape of the Breckland as well as Tresco on the Isles of Scilly.
+The adult male is 90–105 cm (35–41 in) in length, its tail accounting for two-thirds of the total length. It is unmistakable with its golden crest and rump and bright red body. The deep orange "cape" can be spread in display, appearing as an alternating black and orange fan that covers all of the face except its bright yellow eye with a pinpoint black pupil.
+
+Males have a golden-yellow crest with a hint of red at the tip. The face, throat, chin, and the sides of neck are rusty tan. The wattles and orbital skin are both yellow in colour, and the ruff or cape is light orange. The upper back is green and the rest of the back and rump is golden-yellow. The tertiaries are blue whereas the scapulars are dark red. Other characteristics of the male plumage are the central tail feathers, black spotted with cinnamon, as well as the tip of the tail being a cinnamon buff. The upper tail coverts are the same colour as the central tail feathers. The male also has a scarlet breast, and scarlet and light chestnut flanks and underparts. Lower legs and feet are a dull yellow.
+The female (hen) is much less showy, with a duller mottled brown plumage similar to that of the female common pheasant. She is darker and more slender than the hen of that species, with a proportionately shorter tail (half her 60–80 cm (24–31 in) length). The female's breast and sides are barred buff and blackish brown, and the abdomen is plain buff. She has a buff face and throat. Some abnormal females may later in their lifetime get some male plumage. Lower legs and feet are a dull yellow.
+Both males and females have yellow legs and yellow bills.
+They feed on the ground on grain, leaves and invertebrates, but they roost in trees at night. During winter, flocks tend to forage close to human settlements at the edge of forest, taking primarily wheat leaves and seeds. While they can fly clumsily in short bursts, they prefer to run and spend most of their time on the ground. This type of flying is commonly known as "flapping flight" and is due to a lack of a deep layer of M. pectoralis pars thoracicus and the tendon that attaches to it. This muscle is commonly attributed to the stabilization of flight in other birds; however, the absence of this deep layer causes this mode of "flapping flight" is simply a mechanism that it shares with other ground birds in order to escape predators. However, they would rather prefer to simply run away and hide from their predators rather than to fly. If startled, they can suddenly burst upwards at great speed and with a distinctive wing sound.
+Golden pheasants lay 8 to 12 eggs at a time and will then incubate these for around 22–23 days. They tend to eat berries, grubs, seeds and other types of vegetation.
+The male has a metallic call in the breeding season.
+The golden pheasant is commonly found in zoos and aviaries, but often as hybrid specimens that have the similar Lady Amherst's pheasant in their lineage.
+There are also different mutations of the golden pheasant known from birds in captivity, including the dark-throated, yellow, cinnamon, salmon, peach, splash, mahogany and silver. In aviculture, the wild type is referred to as "red-golden" to differentiate it from these mutations.
+The coloration in the feathers can be an indication to the genetic quality of the male golden pheasant. hue, brightness, and chroma are usually measured to see color differences. results show that heterozygosity of the most polymorphic major histocompatibility complex locus was highly related with the chroma and brightness of the feathers.

+The mantled guereza (Colobus guereza), also known simply as the guereza, the eastern black-and-white colobus, or the Abyssinian black-and-white colobus, is a black-and-white colobus, a type of Old World monkey. It is native to much of west central and east Africa, including Cameroon, Equatorial Guinea, Nigeria, Ethiopia, Kenya, Tanzania, Uganda and Chad. The species consists of several subspecies that differ in appearance. It has a distinctive appearance, which is alluded to in its name; the long white fringes of hair that run along each side of its black trunk are known as a mantle. Its face is framed with white hair and it has a large white tail tuft.
+The mantled guereza is diurnal and arboreal, found in both deciduous and evergreen forests. It is an adaptable species that can cope with habitat disturbance and prefers secondary forest close to rivers or lakes. Although previously thought only to eat leaves, it also eats seeds, fruits, and arthropods. It is able to digest plant material with a high fibre content with its specialised stomach and may only eat from a few plant species at a time. It is preyed on by birds of prey and some mammals, such as the common chimpanzee and the leopard.
+The mantled guereza lives in social groups of three to fifteen individuals. These groups normally include a dominant male, several females, and the offspring of the females. It has a polygynous mating system and copulation is initiated with vocal communication. After a gestation period of just over five months, infants are born with pink skin and white fur, which darkens to the adult coloration by three to four months. The mantled guereza is well known for its dawn chorus, the males' "roar" is a method of long-distance communication that reinforces territorial boundaries. It also makes other vocalization and uses body postures, movements, and facial expressions to communicate.
+The mantled guereza is listed as Least Concern by the International Union for Conservation of Nature (IUCN) because it is widespread – although it is locally threatened in some areas, the decline is not great enough to list it in a higher category of threat. However, one subspecies found in Kenya is listed as Endangered. It can survive well in degraded forests and in some areas it is more common in logged areas than unlogged ones. The mantled guereza is also threatened by hunting for bushmeat and for its skin.
+
+
+== Etymology ==
+The mantled guereza has many alternative common names including the guereza, the eastern black-and-white colobus, the magistrate colobus, or the Abyssinian black-and-white colobus. The name "mantled" refers to its mantle, the long silky white fringes of hair that run along its body and "guereza" is the native name of the monkey in Ethiopia. The scientific name Colobus derives from Greek kolobus meaning "mutilated" which refers to its lack of thumbs.
+
+
+== Taxonomic classification ==
+The mantled guereza was first classified by Eduard Rüppell, a German naturalist and explorer, during his trip to Abyssinia between 1830 and 1834. He wrote about the species in Neue Wirbelthiere con Abyssinien, Saengthiere in 1835. It was first seen in Europe in 1890 in Berlin Zoological Garden when three individuals were purchased from a dealer from Massawa, Eritrea.
+
+The mantled guereza is in the Colobinae subfamily, also known as the leaf-eating monkeys, a group of Old World monkeys from Asia and Africa. This subfamily is split into three groups, the colobus monkeys of Africa, of which the mantled guereza is a part, the langurs, or leaf monkeys, of Asia, and an "odd-nosed" group. The African colobus monkeys are divided again by distinctions in color, behavior, and ecology. The three genera are the black-and-white colobi, the red colobi, and the olive colobi. There are three black-and-white colobi: the mantled guereza, Colobus guereza, the king colobus, C. polykomos, and the Angola colobus, C. angolensis. Groves lists seven subspecies of mantled guereza in Mammal Species of the World (MSW) (2005). The validity of the Djaffa Mountain guereza, C. g. gallarum, is uncertain, although not listed by Groves in MSW, it is recognised in his 2007 Colobinae review paper, and by International Union for Conservation of Nature (IUCN) assessors Gippolliti and Butynski in 2008.
+Western guereza, Colobus guereza occidentalis, occurs from eastern Nigeria, Cameroon, and Gabon at the edge of its western range to South Sudan and Uganda, west of the Nile.
+Omo River guereza or Abyssinian black-and-white colobus, C. g. guereza, found in Ethiopia, in the highlands west of the Rift Valley down to the reaches of the Awash River, the Omo River, and in the Blue Nile gorge.
+Djaffa Mountains guereza or Neumann's black-and-white colobus, C. g. gallarum, found in the Ethiopian Highlands east of the Rift Valley.
+Dodinga Hills guereza, C. g. dodingae, found in the Didinga Hills in South Sudan.
+Mau Forest guereza, C. g. matschiei, occurs from western Kenya and Uganda south into northern Tanzania.
+Mt Uaraguess guereza or Percival's black-and-white colobus, C. g. percivali, found in the Matthews Range in Kenya.
+Eastern black-and-white colobus, C. g. kikuyuensis, occurs in Kenya on the Ngong Escarpment of Mount Kenya and in the Aberdare Range.
+Kilimanjaro guereza, C. g. caudatus, found in Tanzania and Kenya in the forests surrounding Mount Kilimanjaro and Mount Meru.The morphological difference between subspecies is most pronounced between the southeastern Kilimanjaro guereza, C. g. caudatus, and the northwestern western guereza, C. g. occidentalis. The intermediate subspecies show a gradual change between the two.

+
+== Physical description ==
+
+The mantled guereza has a distinctive pelage, it is mostly black, with long white fringes of silky hair—known as a mantle or ornamentation—along the sides of its body and tail. The bands that make up the mantle start at the shoulders and extend along the back until they connect at the lower torso. The tail is long and ends in a white tuft which varies in how much it covers the tail. These features vary in color among subspecies, for example the tail of C. g. guereza is gray until the white tail tuft which covers half of its length, while the tail tuft of C. g. caudatus makes up 80% of the tail. The mantle color ranges from white to cream or yellow. Its face is framed by white hair and it has bushy cheek hairs. The thigh has a white stripe.Infants are born with pink skin and white hair. The hair and skin darken as they age and by three to four months they attain adult coloration. Male usually gain their coloration before females. The male typically weighs 9.3 and 13.5 kilograms (21 and 30 lb) and the female weighs between 7.8 and 9.2 kilograms (17 and 20 lb). The head and body length averages 61.5 centimetres (24.2 in) for males and 57.6 centimetres (22.7 in) for females. Like most colobi, the mantled guereza has a small thumb that is vestigial. There is dentition sexual dimorphism among the subspecies. In some, the males have larger teeth than females, in others the reverse is true, and some have no significant difference.
+
+
+== Distribution and habitat ==
+
+The mantled guereza is distributed throughout Equatorial Africa. It ranges from Nigeria and Cameroon in the west to Ethiopia, Kenya, Uganda, and northern Tanzania in the east. The mantled guereza lives in both deciduous and evergreen forests. It mainly inhabits forest and savannah woodlands and often extend into highland and montane forests. It can be found in other forest habitats, both primary and secondary, such as riparian (near fresh or brackish water), gallery, and upland forests. It is particularly common in forests close to rivers and lakes and at high elevations. It can be found in elevations as high as 3,300 metres (10,800 ft). This species prefers secondary forests and selects them over old-growth forests if given the choice. It is likely that the mantled guereza prefers these forests due to the increased number of food trees and the weaker chemical defenses of the species within. The mantled guereza is sometimes found in swamps as well as human-made habitats such as Eucalyptus plantations, which may be frequented when the monkey has nutritional deficiencies.
+
+
+== Ecology ==
+The mantled guereza is primarily arboreal, but does sometimes descend on the ground to forage and travel, perhaps more so than most other colobines. It is diurnal and rests for up to half the day. Foraging or travelling are the next most common activity. Sometime after dawn, mantled guereza groups leave their sleeping trees and will return to them at dusk. During the day, the mantled guereza has long rest periods in between periods of moving and feeding. Other activities, including grooming, greeting, playing and being vigilant, are performed to a lesser extent.
+
+Despite its reputation as an exclusive leaf-eater, the mantled guereza is not an obligate folivore. While it mainly eats leaves and fruit, its diet is quite variable. It may eat bark, wood, seeds, flowers, petioles, lianas, aquatic-plants, arthropods, soil, and even concrete from buildings. The amount of each food item in its diet varies by area and time of year. Nutritional factors like protein, tannins, and sodium levels in leaves influence its food choices. It may even intermittently travel longer distances to access plants with higher levels of nutrition. Leaves usually make up over half of its diet, although fruits are occasionally eaten more depending on the season. When foraging for leaves, the mantled guereza prefers young ones over old. With fleshy fruits, the mantled guereza prefers to eat them unripe, which may serve to reduce competition with primates that eat ripe fruits. It consumes a number of plant species but only some make up most of its diet at a specific site.Like all colobi, the mantled guereza is able to digest leaves and other plant fibers with a large, multi-chambered stomach that contains bacteria in certain areas. Like most colobines, it prefers foods with high fiber content that can be easily extracted with its specialized stomach. The mantled guereza is mostly preyed on by the crowned hawk-eagle, but it is also eaten by other birds of prey such as Verreaux's eagle. The common chimpanzee is known to hunt the guereza. The leopard is another possible predator.
+
+
+== Behaviour ==
+
+
+=== Social structure ===
+
+The mantled guereza lives in stable social groups usually containing three to fifteen members. The groups usually contain one male, several females and juveniles. In some populations, groups containing several males are common. In multi-male groups, males tend to be aggressive with one another with one being dominant. Some males may be expelled from these groups. Multi-male groups may contain father-son pairs or unrelated males. Males that are not part of groups either live solitarily or with other outside males in bachelor groups. The females keep the groups cohesive and they are matrilineally related. They rarely disperse from their natal groups, except possibly when they break apart. Males on the other hand, usually leave when they become subadults or adults. They may start out being solitary and or in bachelor groups. They gain entry into a social group either by being on the periphery or displacing a group male.Because of its low quality diet and the dispersed distribution of its food, the mantled guereza has a resident-egalitarian social structure. Female guerezas living in a group often have an egalitarian dominance style with no formalized rank relations. Relationships are relaxed and friendly with rare signals of dominance or subordinance. Physical aggression within the group is usually not harmful and rarely escalates into a conflict. Allogrooming is an important part of mantled guereza interactions and mostly occurs between females. The adult males rarely groom in the groups. While not strictly territorial, mantled guereza groups can be aggressive towards each other. In some populations, groups may defend core areas (which exist as a small part of the home range), resources, and mates. During intergroup encounters, males can engage in direct or indirect mate defense, like defending a female's resources. It is the males that participate in agonistic inter-group encounters but female may do so as well. Aggressive encounters between groups usually involve chases, displays and vocalizations rather than physical contact.
+
+
+=== Reproduction and parenting ===
+
+The mantled guereza has a polygynous harem-based mating system. Mating solicitations are made by both males and females, half of the time for each. To solicit mating, the mantled guereza will walk near its potential partner and make low-intensity mouth clicks or tough-smacks. During copulation, the males hold on the female's ankles and body. Most matings take place between individuals of the same group but copulations outside of the group have been recorded. In multi-male groups, more than one male may mate with the females. The gestation period lasts 158 days with a 16–22 month interbirth interval. The newborn guereza relies on its mother for support and must cling to her. As they grow older, infants can move on their own but keep returning to their mothers. The infants take up most of the attention in the groups. The other females in a group may handle an infant although the latter are only comfortable with their mothers. The males normally don't pay much attention to infants until they are four to five weeks old. Infants can eat solid food at about eight to nine weeks and by fifty weeks they are fully weaned and no longer need to hold on to their mothers.
+
+
+=== Communication ===
+The most notable vocalization of the mantled guereza is the "roar", which is made mainly at night or dawn by males. The sound of a roar can be carried for up to a mile. It is normally the dominant male who roars when there are multiple males in the group. Roars are used for long-distance communication and can regulate inter-group spacing without direct, physical contact while foraging. When one male starts roaring, neighboring males will start to roar as well. Often, the mantled guereza will respond to calls regardless of "caller identity," focusing more on the collective vocal displays and not the familiarity of the caller. There is variation in the roars of males which could signal the status of their group and fighting ability. With a roar, a male can advertise his body size; both actual and exaggerated. Other vocalizations are made as well. Males may snort, possibly as an alarm call. "Purrs" are made before group movements. Females and infants may "caw" when under mild distress. When in more serious distress, like if an infant is in danger, females and sub-adults will squeak or scream. "Tongue-clicking" is made during mild aggression. In addition to vocalizations, the mantled guereza communicates with several different body postures and movements, displaying of fringe fur, facial expressions, and touches.
+
+
+== Conservation status ==
+
+Because it can live in both dry and gallery forests and move on the ground, the mantled guereza is less threatened than many other colobine species. The IUCN lists it as Least Concern because "although locally threatened in parts of its range, this widespread species is not thought to be declining fast enough to place it in a higher category of threat." However, some of the subspecies are classified under different categories. The Mt Uaraguess guereza, C. g. percivali, is listed as Endangered due to its small range and its risk from hunting, while the Dodinga Hills guereza, C. g. dodingae, the Djaffa Mountains guereza, C. g. gallarum, and the Mau Forest guereza, C. g. matschiei are all listed as Data Deficient.The Dodinga Hills guereza hasn't been recorded since the 1960s. Unlike most other primate species, the mantled guereza can survive habitat degradation and can even thrive in degraded forests. Sometimes, logging may increase the number of preferred food trees for the mantled guereza and it is more abundant in logged areas than unlogged ones. However, complete forest clearance causes dramatic declines in numbers. In Uganda complete forest clearings caused a decline of 50% over eight years. The mantled guereza is also threatened by hunting for meat and its skin. Mantled guereza meat sells as bushmeat for $4–9 US. The skins have been sold for fashion or in the tourist trade.

+Western guereza, Colobus guereza occidentalis, occurs from eastern Nigeria, Cameroon, and Gabon at the edge of its western range to South Sudan and Uganda, west of the Nile.
+Omo River guereza or Abyssinian black-and-white colobus, C. g. guereza, found in Ethiopia, in the highlands west of the Rift Valley down to the reaches of the Awash River, the Omo River, and in the Blue Nile gorge.
+Djaffa Mountains guereza or Neumann's black-and-white colobus, C. g. gallarum, found in the Ethiopian Highlands east of the Rift Valley.
+Dodinga Hills guereza, C. g. dodingae, found in the Didinga Hills in South Sudan.
+Mau Forest guereza, C. g. matschiei, occurs from western Kenya and Uganda south into northern Tanzania.
+Mt Uaraguess guereza or Percival's black-and-white colobus, C. g. percivali, found in the Matthews Range in Kenya.
+Eastern black-and-white colobus, C. g. kikuyuensis, occurs in Kenya on the Ngong Escarpment of Mount Kenya and in the Aberdare Range.
+Kilimanjaro guereza, C. g. caudatus, found in Tanzania and Kenya in the forests surrounding Mount Kilimanjaro and Mount Meru.The morphological difference between subspecies is most pronounced between the southeastern Kilimanjaro guereza, C. g. caudatus, and the northwestern western guereza, C. g. occidentalis. The intermediate subspecies show a gradual change between the two.

+== Physical description ==
+
+The mantled guereza has a distinctive pelage, it is mostly black, with long white fringes of silky hair—known as a mantle or ornamentation—along the sides of its body and tail. The bands that make up the mantle start at the shoulders and extend along the back until they connect at the lower torso. The tail is long and ends in a white tuft which varies in how much it covers the tail. These features vary in color among subspecies, for example the tail of C. g. guereza is gray until the white tail tuft which covers half of its length, while the tail tuft of C. g. caudatus makes up 80% of the tail. The mantle color ranges from white to cream or yellow. Its face is framed by white hair and it has bushy cheek hairs. The thigh has a white stripe.Infants are born with pink skin and white hair. The hair and skin darken as they age and by three to four months they attain adult coloration. Male usually gain their coloration before females. The male typically weighs 9.3 and 13.5 kilograms (21 and 30 lb) and the female weighs between 7.8 and 9.2 kilograms (17 and 20 lb). The head and body length averages 61.5 centimetres (24.2 in) for males and 57.6 centimetres (22.7 in) for females. Like most colobi, the mantled guereza has a small thumb that is vestigial. There is dentition sexual dimorphism among the subspecies. In some, the males have larger teeth than females, in others the reverse is true, and some have no significant difference.
+
+
+== Distribution and habitat ==
+
+The mantled guereza is distributed throughout Equatorial Africa. It ranges from Nigeria and Cameroon in the west to Ethiopia, Kenya, Uganda, and northern Tanzania in the east. The mantled guereza lives in both deciduous and evergreen forests. It mainly inhabits forest and savannah woodlands and often extend into highland and montane forests. It can be found in other forest habitats, both primary and secondary, such as riparian (near fresh or brackish water), gallery, and upland forests. It is particularly common in forests close to rivers and lakes and at high elevations. It can be found in elevations as high as 3,300 metres (10,800 ft). This species prefers secondary forests and selects them over old-growth forests if given the choice. It is likely that the mantled guereza prefers these forests due to the increased number of food trees and the weaker chemical defenses of the species within. The mantled guereza is sometimes found in swamps as well as human-made habitats such as Eucalyptus plantations, which may be frequented when the monkey has nutritional deficiencies.
+
+
+== Ecology ==
+The mantled guereza is primarily arboreal, but does sometimes descend on the ground to forage and travel, perhaps more so than most other colobines. It is diurnal and rests for up to half the day. Foraging or travelling are the next most common activity. Sometime after dawn, mantled guereza groups leave their sleeping trees and will return to them at dusk. During the day, the mantled guereza has long rest periods in between periods of moving and feeding. Other activities, including grooming, greeting, playing and being vigilant, are performed to a lesser extent.
+
+Despite its reputation as an exclusive leaf-eater, the mantled guereza is not an obligate folivore. While it mainly eats leaves and fruit, its diet is quite variable. It may eat bark, wood, seeds, flowers, petioles, lianas, aquatic-plants, arthropods, soil, and even concrete from buildings. The amount of each food item in its diet varies by area and time of year. Nutritional factors like protein, tannins, and sodium levels in leaves influence its food choices. It may even intermittently travel longer distances to access plants with higher levels of nutrition. Leaves usually make up over half of its diet, although fruits are occasionally eaten more depending on the season. When foraging for leaves, the mantled guereza prefers young ones over old. With fleshy fruits, the mantled guereza prefers to eat them unripe, which may serve to reduce competition with primates that eat ripe fruits. It consumes a number of plant species but only some make up most of its diet at a specific site.Like all colobi, the mantled guereza is able to digest leaves and other plant fibers with a large, multi-chambered stomach that contains bacteria in certain areas. Like most colobines, it prefers foods with high fiber content that can be easily extracted with its specialized stomach. The mantled guereza is mostly preyed on by the crowned hawk-eagle, but it is also eaten by other birds of prey such as Verreaux's eagle. The common chimpanzee is known to hunt the guereza. The leopard is another possible predator.
+
+
+== Behaviour ==
+
+
+=== Social structure ===
+
+The mantled guereza lives in stable social groups usually containing three to fifteen members. The groups usually contain one male, several females and juveniles. In some populations, groups containing several males are common. In multi-male groups, males tend to be aggressive with one another with one being dominant. Some males may be expelled from these groups. Multi-male groups may contain father-son pairs or unrelated males. Males that are not part of groups either live solitarily or with other outside males in bachelor groups. The females keep the groups cohesive and they are matrilineally related. They rarely disperse from their natal groups, except possibly when they break apart. Males on the other hand, usually leave when they become subadults or adults. They may start out being solitary and or in bachelor groups. They gain entry into a social group either by being on the periphery or displacing a group male.Because of its low quality diet and the dispersed distribution of its food, the mantled guereza has a resident-egalitarian social structure. Female guerezas living in a group often have an egalitarian dominance style with no formalized rank relations. Relationships are relaxed and friendly with rare signals of dominance or subordinance. Physical aggression within the group is usually not harmful and rarely escalates into a conflict. Allogrooming is an important part of mantled guereza interactions and mostly occurs between females. The adult males rarely groom in the groups. While not strictly territorial, mantled guereza groups can be aggressive towards each other. In some populations, groups may defend core areas (which exist as a small part of the home range), resources, and mates. During intergroup encounters, males can engage in direct or indirect mate defense, like defending a female's resources. It is the males that participate in agonistic inter-group encounters but female may do so as well. Aggressive encounters between groups usually involve chases, displays and vocalizations rather than physical contact.
+
+
+=== Reproduction and parenting ===
+
+The mantled guereza has a polygynous harem-based mating system. Mating solicitations are made by both males and females, half of the time for each. To solicit mating, the mantled guereza will walk near its potential partner and make low-intensity mouth clicks or tough-smacks. During copulation, the males hold on the female's ankles and body. Most matings take place between individuals of the same group but copulations outside of the group have been recorded. In multi-male groups, more than one male may mate with the females. The gestation period lasts 158 days with a 16–22 month interbirth interval. The newborn guereza relies on its mother for support and must cling to her. As they grow older, infants can move on their own but keep returning to their mothers. The infants take up most of the attention in the groups. The other females in a group may handle an infant although the latter are only comfortable with their mothers. The males normally don't pay much attention to infants until they are four to five weeks old. Infants can eat solid food at about eight to nine weeks and by fifty weeks they are fully weaned and no longer need to hold on to their mothers.
+
+
+=== Communication ===
+The most notable vocalization of the mantled guereza is the "roar", which is made mainly at night or dawn by males. The sound of a roar can be carried for up to a mile. It is normally the dominant male who roars when there are multiple males in the group. Roars are used for long-distance communication and can regulate inter-group spacing without direct, physical contact while foraging. When one male starts roaring, neighboring males will start to roar as well. Often, the mantled guereza will respond to calls regardless of "caller identity," focusing more on the collective vocal displays and not the familiarity of the caller. There is variation in the roars of males which could signal the status of their group and fighting ability. With a roar, a male can advertise his body size; both actual and exaggerated. Other vocalizations are made as well. Males may snort, possibly as an alarm call. "Purrs" are made before group movements. Females and infants may "caw" when under mild distress. When in more serious distress, like if an infant is in danger, females and sub-adults will squeak or scream. "Tongue-clicking" is made during mild aggression. In addition to vocalizations, the mantled guereza communicates with several different body postures and movements, displaying of fringe fur, facial expressions, and touches.
+
+
+== Conservation status ==
+
+Because it can live in both dry and gallery forests and move on the ground, the mantled guereza is less threatened than many other colobine species. The IUCN lists it as Least Concern because "although locally threatened in parts of its range, this widespread species is not thought to be declining fast enough to place it in a higher category of threat." However, some of the subspecies are classified under different categories. The Mt Uaraguess guereza, C. g. percivali, is listed as Endangered due to its small range and its risk from hunting, while the Dodinga Hills guereza, C. g. dodingae, the Djaffa Mountains guereza, C. g. gallarum, and the Mau Forest guereza, C. g. matschiei are all listed as Data Deficient.The Dodinga Hills guereza hasn't been recorded since the 1960s. Unlike most other primate species, the mantled guereza can survive habitat degradation and can even thrive in degraded forests. Sometimes, logging may increase the number of preferred food trees for the mantled guereza and it is more abundant in logged areas than unlogged ones. However, complete forest clearance causes dramatic declines in numbers. In Uganda complete forest clearings caused a decline of 50% over eight years. The mantled guereza is also threatened by hunting for meat and its skin. Mantled guereza meat sells as bushmeat for $4–9 US. The skins have been sold for fashion or in the tourist trade.

+The lesser vasa parrot or black parrot (Coracopsis nigra) is a black coloured parrot endemic to most of Madagascar. It is one of four species of vasa parrots, the others being the greater vasa parrot C. vasa, the Seychelles black parrot (C. barklyi), and the Comoros black parrot (C. sibilans). The latter two were formerly considered conspecific with the lesser vasa parrot.Lesser vasa parrots inhabit the mangrove swamps and evergreen forests of Madagascar. They eat seeds, blossoms and fruit - especially berries and mangos.
+They build their nests in tree hollows and go through courtship in February.  During this time, the female may shed the feathers on her head giving it a yellowish tone.  The male's beak may also turn white during this time.
+
+
+== Taxonomy ==
+In 1743 the English naturalist George Edwards included a picture and a description of the lesser vasa parrot in his A Natural History of Uncommon Birds. He used the English name "Black Parrot from Madagascar". His drawing was made from a live bird owned by the Duke of Richmond. When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he placed the lesser vasa parrot with all the other parrots in the genus Psittacus. Linnaeus included a brief description, coined the binomial name Psittacus niger and cited Edwards's work. The specific epithet niger is Latin meaning "black".  The lesser vasa parrot is now placed in the genus Coracopsis that was introduced in 1832 by the German ornithologist Johann Georg Wagler.There are two subspecies:
+Coracopsis nigra libs, Bangs 1927
+Coracopsis nigra nigra, (Linnaeus, 1758)The Seychelles black parrot (C. barklyi) and Comoros black parrot (C. sibilans) were formerly considered subspecies, but were later split as distinct species.A 2011 genetic study found the Mascarene parrot from Réunion to be nested among the subspecies of the lesser vasa parrot from Madagascar and nearby islands, and therefore not related to the Psittacula parrots. It also found that the Mascarene parrot line diverged 4.6 to 9 million years ago, prior to the formation of Réunion, indicating this must have happened elsewhere. The cladogram accompanying the study is shown below:
+Another group of scientists later acknowledged the finding, but pointed out that the sample might have been damaged, and that further testing was needed before the issue could be fully resolved. They also noted that if Mascarinus was confirmed to be embedded within the genus Coracopsis, the latter would become a junior synonym, since the former name is older. Hume has expressed surprise by these findings, due to the anatomical similarities between the Mascarene parrot and other parrots from the islands that are believed to be psittaculines. However, a later study found that the placement of Mascarinus within Coracopsis was likely a result of cross-contamination of genetic material from the lesser vasa parrot during the study, debunking this placement, and supporting them as being two distinct, unrelated genera within different subfamilies.

+The Nile crocodile (Crocodylus niloticus) is a large crocodilian native to freshwater habitats in Africa, where it is present in 26 countries. It is widely distributed throughout sub-Saharan Africa, occurring mostly in the central, eastern, and southern regions of the continent, and lives in different types of aquatic environments such as lakes, rivers, swamps, and marshlands. In West Africa, it occurs along with two other crocodilians. Although capable of living in saline environments, this species is rarely found in saltwater, but occasionally inhabits deltas and brackish lakes. The range of this species once stretched northward throughout the Nile, as far north as the Nile Delta. On average, the adult male Nile crocodile is between 2.94 and 4.4 m (9 ft 8 in and 14 ft 5 in) in length and weighs 225 to 414.5 kg (496 to 914 lb) including stomach stones. However, specimens exceeding 6.1 m (20 ft) in length and weighing up to 1,089 kg (2,401 lb) have been recorded. It is the largest freshwater predator in Africa, and may be considered the second-largest extant reptile in the world, after the saltwater crocodile (Crocodylus porosus). Size is sexually dimorphic, with females usually about 30% smaller than males. The crocodile has thick, scaly, heavily armoured skin. 
+Nile crocodiles are opportunistic apex predators; a very aggressive crocodile, they are capable of taking almost any animal within their range. They are generalists, taking a variety of prey. Their diet consists mostly of different species of fish, reptiles, birds, and mammals. They are ambush predators that can wait for hours, days, and even weeks for the suitable moment to attack. They are agile predators and wait for the opportunity for a prey item to come well within attack range. Even swift prey are not immune to attack. Like other crocodiles, Nile crocodiles have a powerful bite that is unique among all animals, and sharp, conical teeth that sink into flesh, allowing a grip that is almost impossible to loosen. They can apply high force for extended periods of time, a great advantage for holding down large prey underwater to drown.Nile crocodiles are relatively social. They share basking spots and large food sources, such as schools of fish and big carcasses. Their strict hierarchy is determined by size. Large, old males are at the top of this hierarchy and have first access to food and the best basking spots. Crocodiles tend to respect this order; when it is infringed, the results are often violent and sometimes fatal. Like most other reptiles, Nile crocodiles lay eggs; these are guarded by the females. The hatchlings are also protected for a period of time, but hunt by themselves and are not fed by the parents.The Nile crocodile is one of the most dangerous species of crocodile and is responsible for hundreds of human deaths every year. It is common and is not endangered, despite some regional declines or extirpations.
+
+
+== Etymology and naming ==
+The binomial name Crocodylus niloticus is derived from the Greek κρόκη, kroke ("pebble"), δρῖλος, drilos ("worm"), referring to its rough skin; and niloticus, meaning "from the Nile River". The Nile crocodile is called timsah al-nil in Arabic, mamba in Swahili, garwe in Shona, ngwenya in Ndebele, ngwena in Venda, kwena in Sotho and Tswana, and tanin ha-yeor in Hebrew. It also sometimes referred to as the African crocodile, Ethiopian crocodile, and common crocodile.
+
+
+== Taxonomy ==
+Although no subspecies are currently formally recognized, as many as seven have been proposed, mostly due to variations in appearance and size noted in various populations throughout Africa. These have consisted of C. n. africanus (informally named the East African Nile crocodile), C. n. chamses (the West African Nile crocodile), C. n. cowiei (the South African Nile crocodile), C. n. madagascariensis (the Malagasy or Madagascar Nile crocodile, regionally also known as the croco Mada, which translates to Malagasy crocodile), C. n. niloticus (the Ethiopian Nile crocodile; this would be the nominate subspecies), C. n. pauciscutatus (the Kenyan Nile crocodile) and C. (n.) suchus (now widely considered a separate species).In a study of the morphology of the various populations, including C. (n.) suchus, the appearance of the Nile crocodile sensu lato was found to be more variable than that of any other currently recognized crocodile species, and at least some of these variations were related to locality. For example, a study on Lake Turkana in Kenya (informally this population would be placed in C. n. pauciscutatus) found that the local crocodiles have more osteoderms in their ventral surface than other known populations, and thus are of lesser value in leather trading, accounting for an exceptionally large (possibly overpopulated) local population there in the late 20th century. The segregation of the West African crocodile (C. suchus) from the Nile crocodile has been supported by morphological characteristics, studies of genetic materials and habitat preferences. The separation of the two is not recognized by the IUCN as their last evaluations of the group was in 2008 and 2009, years before the primary publications supporting the distinctiveness of the West African crocodiles.
+
+
+== Evolution ==
+Although originally thought to be the same species as the West African crocodile, genetic studies using DNA sequencing have revealed that the Nile crocodile is actually more closely related to the crocodiles of the Americas, namely the American (C. acutus), Cuban (C. rhombifer), Morelet's (C. moreletii), and Orinoco crocodiles (C. intermedius). The fossil species C. checchiai from the Miocene in Kenya was about the same size as the modern Nile crocodiles and shared similar physical characteristics to the modern species, and analysis of C. checchiai supports their close relationship and the theory of the Nile crocodile being the base of the evolutionary radiation of the New World crocodiles. Dispersal across the Atlantic from Africa is thought to have occurred 5 to 6 million years ago.At one time, the fossil species Rimasuchus lloydi was thought to be the ancestor of the Nile crocodile, but more recent research has indicated that Rimasuchus, despite its very large size (about 20–30% bigger than a Nile crocodile with a skull length estimated up to 97 cm (38 in)), is more closely related to the dwarf crocodile (Osteolaemus tetraspis) among living species. Two other fossil species from Africa retained in the genus Crocodylus appear to be closely related to the Nile crocodile: C. anthropophagus from Plio-Pleistocene Tanzania and C. thorbjarnarsoni from Plio-Pleistocene Kenya. C. anthropophagus and C. thorbjarnarsoni were both somewhat larger, with projected total lengths up to 7.5–7.6 m (24 ft 7 in – 24 ft 11 in). As well as being larger, C. anthropophagus and C. thorbjarnarsoni, as well as Rimasuchus spp., were all relatively broad-snouted, indicating a specialization at hunting sizeable prey, such as large mammals and freshwater turtles, the latter much larger than any in present-day Africa. Studies have since shown these other African crocodiles to be only more distantly related to the Nile crocodile.Below is a cladogram based on a 2018 tip dating study by Lee & Yates simultaneously using morphological, molecular (DNA sequencing), and stratigraphic (fossil age) data, as revised by the 2021 Hekkala et al. paleogenomics study using DNA extracted from the extinct Voay.
+
+
+== Characteristics and physiology ==
+
+Adult Nile crocodiles have a dark bronze colouration above, with faded blackish spots and stripes variably appearing across the back and a dingy off-yellow on the belly, although mud can often obscure the crocodile's actual colour. The flanks, which are yellowish-green in colour, have dark patches arranged in oblique stripes in highly variable patterns. Some variation occurs relative to environment; specimens from swift-flowing waters tend to be lighter in colour than those dwelling in murkier lakes or swamps, which provides camouflage that suits their environment, an example of clinal variation. Nile crocodiles have green eyes. The colouration also helps to camouflage them; juveniles are grey, multicoloured, or brown, with dark cross-bands on the tail and body. The underbelly of young crocodiles is yellowish green. As they mature, Nile crocodiles become darker and the cross-bands fade, especially those on the upper-body. A similar tendency in coloration change during maturation has been noted in most crocodile species.Most morphological attributes of Nile crocodiles are typical of crocodilians as a whole. Like all crocodilians, for example, the Nile crocodile is a quadruped with four short, splayed legs, a long, powerful tail, a scaly hide with rows of ossified scutes running down its back and tail, and powerful, elongated jaws. Their skin has a number of poorly understood integumentary sense organs that may react to changes in water pressure, presumably allowing them to track prey movements in the water. The Nile crocodile has fewer osteoderms on the belly, which are much more conspicuous on some of the more modestly sized crocodilians. The species, however, also has small, oval osteoderms on the sides of the body, as well as the throat. The Nile crocodile shares with all crocodilians a nictitating membrane to protect the eyes and lachrymal glands to cleanse its eyes with tears. The nostrils, eyes, and ears are situated on the top of the head, so the rest of the body can remain concealed under water. They have a four-chambered heart, although modified for their ectothermic nature due to an elongated cardiac septum, physiologically similar to the heart of a bird, which is especially efficient at oxygenating their blood. As in all crocodilians, Nile crocodiles have exceptionally high levels of lactic acid in their blood, which allows them to sit motionless in water for up to 2 hours. Levels of lactic acid as high as they are in a crocodile would kill most vertebrates. However, exertion by crocodilians can lead to death due to increasing lactic acid to lethal levels, which in turn leads to failure of the animal's internal organs. This is rarely recorded in wild crocodiles, normally having been observed in cases where humans have mishandled crocodiles and put them through overly extended periods of physical struggling and stress.

+
+=== Skull and head morphology ===
+
+The mouths of Nile crocodiles are filled with 64 to 68 sharply pointed, cone-shaped teeth (about a dozen less than alligators have). For most of a crocodile's life, broken teeth can be replaced. On each side of the mouth, five teeth are in the front of the upper jaw (premaxilla), 13 or 14 are in the rest of the upper jaw (maxilla), and 14 or 15 are on either side of the lower jaw (mandible). The enlarged fourth lower tooth fits into the notch on the upper jaw and is visible when the jaws are closed, as is the case with all true crocodiles. Hatchlings quickly lose a hardened piece of skin on the top of their mouths called the egg tooth, which they use to break through their eggshells at hatching. Among crocodilians, the Nile crocodile possesses a relatively long snout, which is about 1.6 to 2.0 times as long as broad at the level of the front corners of the eyes. As is the saltwater crocodile, the Nile crocodile is considered a species with medium-width snout relative to other extant crocodilian species.In a search for the largest crocodilian skulls in museums, the largest verifiable Nile crocodile skulls found were several housed in Arba Minch, Ethiopia, sourced from nearby Lake Chamo, which apparently included several specimens with a skull length more than 65 cm (26 in), with the largest one being 68.6 cm (27.0 in) in length with a mandibular length of 87 cm (34 in). Nile crocodiles with skulls this size are likely to measure in the range of 5.4 to 5.6 m (17 ft 9 in to 18 ft 4 in), which is also the length of the animals according to the museum where they were found. However, larger skulls may exist, as this study largely focused on crocodilians from Asia. The detached head of an exceptionally large Nile crocodile (killed in 1968 and measuring 5.87 m (19 ft 3 in) in length) was found to have weighed 166 kg (366 lb), including the large tendons used to shut the jaw.
+
+
+==== Biting force ====
+The bite force exerted by an adult Nile crocodile has been shown by Brady Barr to measure 22 kN (5,000 lbf). However, the muscles responsible for opening the mouth are exceptionally weak, allowing a person to easily hold them shut, and even larger crocodiles can be brought under control by the use of duct tape to bind the jaws together. The broadest snouted modern crocodilians are alligators and larger caimans. For example, a 3.9 m (12 ft 10 in) black caiman (Melanosuchus niger) was found to have a notably broader and heavier skull than that of a Nile crocodile measuring 4.8 m (15 ft 9 in). However, despite their robust skulls, alligators and caimans appear to be proportionately equal in biting force to true crocodiles, as the muscular tendons used to shut the jaws are similar in proportional size. Only the gharial (Gavialis gangeticus) (and perhaps some of the few very thin-snouted crocodilians) is likely to have noticeably diminished bite force compared to other living species due to its exceptionally narrow, fragile snout. More or less, the size of the tendons used to impart bite force increases with body size and the larger the crocodilian gets, the stronger its bite is likely to be. Therefore, a male saltwater crocodile, which had attained a length around 4.59 m (15 ft 1 in), was found to have the most powerful biting force ever tested in a lab setting for any type of animal.
+
+
+=== Size ===
+
+The Nile crocodile is the largest crocodilian in Africa, and is generally considered the second-largest crocodilian after the saltwater crocodile. Typical size has been reported to be as much as 4.5 to 5.5 m (14 ft 9 in to 18 ft 1 in), but this is excessive for actual average size per most studies and represents the upper limit of sizes attained by the largest animals in a majority of populations. Alexander and Marais (2007) give the typical mature size as 2.8 to 3.5 m (9 ft 2 in to 11 ft 6 in); Garrick and Lang (1977) put it at from 3.0 to 4.5 m (9 ft 10 in to 14 ft 9 in). According to Cott (1961), the average length and weight of Nile crocodiles from Uganda and Zambia in breeding maturity was 3.16 m (10 ft 4 in) and 137.5 kg (303 lb). Per Graham (1968), the average length and weight of a large sample of adult crocodiles from Lake Turkana (formerly known as Lake Rudolf), Kenya was 3.66 m (12 ft 0 in) and body mass of 201.6 kg (444 lb). Similarly, adult crocodiles from Kruger National Park reportedly average 3.65 m (12 ft 0 in) in length. In comparison, the saltwater crocodile and gharial reportedly both average around 4 m (13 ft 1 in), so are about 30 cm (12 in) longer on average, and the false gharial (Tomistoma schlegelii) may average about 3.75 m (12 ft 4 in), so may be slightly longer, as well. However, compared to the narrow-snouted, streamlined gharial and false gharial, the Nile crocodile is more robust and ranks second to the saltwater crocodile in total average body mass among living crocodilians, and is  considered to be the second-largest extant reptile. The largest accurately measured male, shot near Mwanza, Tanzania, measured 6.45 m (21 ft 2 in) and weighed about 1,043–1,089 kg (2,300–2,400 lb).
+
+
+==== Size and sexual dimorphism ====
+
+Like all crocodiles, they are sexually dimorphic, with the males up to 30% larger than the females, though the difference is considerably less compared to some species, like the saltwater crocodile. Male Nile crocodiles are about 30 to 50 cm (12 to 20 in) longer on average at sexual maturity and grow more so than females after becoming sexually mature, especially expanding in bulk after exceeding 4 m (13 ft 1 in) in length. Adult male Nile crocodiles usually range in length from 3.3 to 5.0 m (10 ft 10 in to 16 ft 5 in) long; at these lengths, an average sized male may weigh from 150 to 750 kg (330 to 1,650 lb). Very old, mature ones can grow to 5.5 m (18 ft 1 in) or more in length (all specimens over 5.5 m (18 ft 1 in) from 1900 onward are cataloged later). Mature female Nile crocodiles typically measure 2.2 to 3.8 m (7 ft 3 in to 12 ft 6 in), at which lengths the average female specimen would weigh 40 to 250 kg (88 to 551 lb).The bulk and mass of individual crocodiles can be fairly variable, some animals being relatively slender, while others being very robust; females are often bulkier than males of a similar length. As an example of the body mass increase undergone by mature crocodiles, one of the larger crocodiles handled firsthand by Cott (1961) was 4.4 m (14 ft 5 in) and weighed 414.5 kg (914 lb), while the largest specimen measured by Graham and Beard (1973) was 4.8 m (15 ft 9 in) and weighed more than 680 kg (1,500 lb). In attempts to parse the mean male and female lengths across the species, the mean adult length was estimated to be reportedly 4 m (13 ft 1 in) in males, at which males would average about 280 kg (620 lb) in weight, while that of the female is 3.05 m (10 ft 0 in), at which females would average about 116 kg (256 lb). This gives the Nile crocodile somewhat of a size advantage over the next largest non-marine predator on the African continent, the lion (Panthera leo), which averages 188 kg (414 lb) in males and 124 kg (273 lb) in females, and attains a maximum known weight of 313 kg (690 lb), far less than that of large male crocodiles.Nile crocodiles from cooler climates, like the southern tip of Africa, may be smaller, reaching maximum lengths of only 4 m (13 ft 1 in). A crocodile population from Mali, the Sahara Desert, and elsewhere in West Africa reaches only 2 to 3 m (6 ft 7 in to 9 ft 10 in) in length, but it is now largely recognized as a separate species, the West African crocodile.

+
+== Distribution and habitat ==
+The Nile crocodile is presently the most common crocodilian in Africa, and is distributed throughout much of the continent. Among crocodilians today, only the saltwater crocodile occurs over a broader geographic area, although other species, especially the spectacled caiman (Caiman crocodilus) (due to its small size and extreme adaptability in habitat and flexibility in diet), seem to actually be more abundant. This species’ historic range, however, was even wider. They were found as far north as the Mediterranean coast in the Nile Delta and across the Red Sea in Israel, Palestine and Syria. The Nile crocodile has historically been recorded in areas where they are now regionally extinct. For example, Herodotus recorded the species inhabiting Lake Moeris in Egypt. They are thought to have become extinct in the Seychelles in the early 19th century (1810–1820). Today, Nile crocodiles are widely found in, among others, Somalia, Ethiopia, Uganda, Kenya, Egypt, the Central African Republic, the Democratic Republic of the Congo, Equatorial Guinea, Tanzania, Rwanda, Burundi, Zambia, Zimbabwe, Gabon, Angola, South Africa, Malawi, Mozambique, Namibia, Sudan, South Sudan, Botswana, and Cameroon. The Nile crocodile's current range of distribution extends from the regional tributaries of the Nile in Sudan and Lake Nasser in Egypt to the Cunene of Angola, the Okavango Delta of Botswana, and the Olifants River in South Africa.Isolated populations also exist in Madagascar, which likely colonized the island after the extinction of the endemic crocodile Voay. In Madagascar, crocodiles occur in the western and southern parts from Sambirano to Tôlanaro. They have been spotted in Zanzibar and the Comoros in modern times, but occur very rarely.The species was previously thought to extend in range into the whole of West and Central Africa, but these populations are now typically recognized as a distinct species, the West African (or desert) crocodile. The distributional boundaries between these species were poorly understood, but following several studies, they are now better known. West African crocodiles are found throughout much of West and Central Africa, ranging east to South Sudan and Uganda where the species may come into contact with the Nile crocodile. Nile crocodiles are absent from most of West and Central Africa, but range into the latter region in eastern and southern Democratic Republic of Congo, and along the Central African coastal Atlantic region (as far north to Cameroon). Likely a level of habitat segregation occurs between the two species, but this remains to be confirmed.Nile crocodiles may be able to tolerate an extremely broad range of habitat types, including small brackish streams, fast-flowing rivers, swamps, dams, and tidal lakes and estuaries. In East Africa, they are found mostly in rivers, lakes, marshes, and dams, favoring open, broad bodies of water over smaller ones. They are often found in waters adjacent to various open habitats such as savanna or even semi-desert but can also acclimate to well-wooded swamps, extensively wooded riparian zones, waterways of other woodlands and the perimeter of forests. In Madagascar, the remnant population of Nile crocodiles has adapted to living within caves. Nile crocodiles may make use of ephemeral watering holes on occasion. Although not a regular sea-going species as is the American crocodile, and especially the saltwater crocodile, the Nile crocodile possesses salt glands like all true crocodiles (i.e., excluding alligators and caimans), and does on occasion enter coastal and even marine waters. They have been known to enter the sea in some areas, with one specimen having been recorded 11 km (6.8 mi) off St. Lucia Bay in 1917.
+
+
+=== Invasive potential ===
+Nile crocodiles have been recently captured in South Florida, though no signs that the population is reproducing in the wild have been found. Genetic studies of Nile crocodiles captured in the wild in Florida have revealed that the specimens are all closely related to each other, suggesting a single source of the introduction. This source remains unclear, as their genetics do not match samples collected from captives at various zoos and theme parks in Florida. When compared to Nile crocodiles from their native Africa, the Florida wild specimens are most closely related to South African Nile crocodiles. It is unknown how many Nile crocodiles are currently at large in Florida. The animals likely were either brought there to be released or are escapees.
+
+
+== Behaviour ==
+
+Generally, Nile crocodiles are relatively inert creatures, as are most crocodilians and other large, cold-blooded creatures. More than half of the crocodiles observed by Cott (1961), if not disturbed, spent the hours from 9:00 a.m. to 4:00 p.m. continuously basking with their jaws open if conditions were sunny. If their jaws are bound together in the extreme midday heat, Nile crocodiles may easily die from overheating. Although they can remain practically motionless for hours on end, whether basking or sitting in shallows, Nile crocodiles are said to be constantly aware of their surroundings and aware of the presence of other animals. However, mouth-gaping (while essential to thermoregulation) may also serve as a threat display to other crocodiles. For example, some specimens have been observed mouth-gaping at night, when overheating is not a risk. In Lake Turkana, crocodiles rarely bask at all through the day, unlike crocodiles from most other areas, for unknown reasons, usually sitting motionless partially exposed at the surface in shallows, with no apparent ill effects from the lack of basking on land.
+
+In South Africa, Nile crocodiles are more easily observed in winter because of the extensive amount of time they spend basking at this time of year. More time is spent in water on overcast, rainy, or misty days. In the southern reaches of their range, as a response to dry, cool conditions that they cannot survive externally, crocodiles may dig and take refuge in tunnels and engage in aestivation. Pooley found in Royal Natal National Park that during aestivation, young crocodiles of 60 to 90 cm (24 to 35 in) total length would dig tunnels around 1.2 to 1.8 m (3 ft 11 in to 5 ft 11 in) in depth for most, with some tunnels measuring more than 2.7 m (8 ft 10 in), the longest there being 3.65 m (12 ft 0 in). Crocodiles in aestivation are lethargic, entering a state similar to animals that hibernate. Only the largest individuals engaging in aestivation leave the burrow to sun on the warmest days; otherwise, these crocodiles rarely left their burrows. Aestivation has been recorded from May to August.Nile crocodiles usually dive for only a few minutes at a time, but can swim under water up to 30 minutes if threatened. If they remain fully inactive, they can hold their breath for up to 2 hours (which, as aforementioned, is due to the high levels of lactic acid in their blood). They have a rich vocal range and good hearing. Nile crocodiles normally crawl along on their bellies, but they can also "high walk" with their trunks raised above the ground. Smaller specimens can gallop, and even larger individuals are capable of occasional, surprising bursts of speed, briefly reaching up to 14 km/h (8.7 mph). They can swim much faster, moving their bodies and tails in a sinuous fashion, and they can sustain this form of movement much longer than on land, with a maximum known swimming speed of 30 to 35 km/h (19 to 22 mph), more than three times faster than any human.
+
+Nile crocodiles have been widely known to have gastroliths in their stomachs, which are stones swallowed by animals for various purposes. Although this is clearly a deliberate behaviour for the species, the purpose is not definitively known. Gastroliths are not present in hatchlings, but increase quickly in presence within most crocodiles examined at 2–3.1 m (6 ft 7 in – 10 ft 2 in) and yet normally become extremely rare again in very large specimens, meaning that some animals may eventually expel them. However, large specimens can have a large number of gastroliths. One crocodile measuring 3.84 m (12 ft 7 in) and weighing 239 kg (527 lb) had 5.1 kg (11 lb) of stones in its stomach, perhaps a record gastrolith weight for a crocodile. Specimens shot near Mpondwe on the Semliki River had gastroliths in their stomach despite being shot miles away from any sources for the stones; the same holds true for specimens from Kafue Flats, Upper Zambesi and Bangweulu Swamp, all of which often had stones inside them despite being nowhere near stony regions. Cott (1961) felt that gastroliths were most likely serving as ballast to provide stability and additional weight to sink in water, this bearing great probability over the theories that they assist in digestion and staving off hunger. However, Alderton (1998) stated that a study using radiology found that gastroliths were seen to internally aid the grinding of food during digestion for a small Nile crocodile.Herodotus claimed that Nile crocodiles have a symbiotic relationship with certain birds, such as the Egyptian plover (Pluvianus aegyptius), which enter the crocodile's mouth and pick leeches feeding on the crocodile's blood, but no evidence of this interaction actually occurring in any crocodile species has been found, and it is most likely mythical or allegorical fiction. However, Guggisberg (1972) had seen examples of birds picking scraps of meat from the teeth of basking crocodiles (without entering the mouth) and prey from soil very near basking crocodiles, so felt it was not impossible that a bold, hungry bird may occasionally nearly enter a crocodile's mouth, but not likely as a habitual behaviour.
+
+
+== Hunting and diet ==
+
+Nile crocodiles are apex predators throughout their range. In the water, this species is an agile and rapid hunter relying on both movement and pressure sensors to catch any prey unfortunate enough to present itself inside or near the waterfront. Out of water, however, the Nile crocodile can only rely on its limbs, as it gallops on solid ground, to chase prey. No matter where they attack prey, this and other crocodilians take practically all of their food by ambush, needing to grab their prey in a matter of seconds to succeed. They have an ectothermic metabolism, so can survive for long periods between meals. However, for such large animals, their stomachs are relatively small, not much larger than a basketball in an average-sized adult, so as a rule, they are anything but voracious eaters. Young crocodiles feed more actively than their elders, according to studies in Uganda and Zambia. In general, at the smallest sizes (0.3–1 m (1 ft 0 in – 3 ft 3 in)), Nile crocodiles were most likely to have full stomachs (17.4% full per Cott); adults at 3–4 m (9 ft 10 in – 13 ft 1 in) in length were most likely to have empty stomachs (20.2%). In the largest size range studied by Cott, 4–5 m (13 ft 1 in – 16 ft 5 in), they were the second most likely to either have full stomachs (10%) or empty stomachs (20%). Other studies have also shown a large number of adult Nile crocodiles with empty stomachs. For example, in Lake Turkana, Kenya, 48.4% of crocodiles had empty stomachs. The stomachs of brooding females are always empty, meaning that they can survive several months without food.The Nile crocodile mostly hunts within the confines of waterways, attacking aquatic prey or terrestrial animals when they come to the water to drink or to cross. The crocodile mainly hunts land animals by almost fully submerging its body under water. Occasionally, a crocodile quietly surfaces so that only its eyes (to check positioning) and nostrils are visible, and swims quietly and stealthily toward its mark. The attack is sudden and unpredictable. The crocodile lunges its body out of water and grasps its prey. On other occasions, more of its head and upper body is visible, especially when the terrestrial prey animal is on higher ground, to get a sense of the direction of the prey item at the top of an embankment or on a tree branch. Crocodile teeth are not used for tearing up flesh, but to sink deep into it and hold on to the prey item. The immense bite force, which may be as high as 5,000 lbf (22,000 N) in large adults, ensures that the prey item cannot escape the grip. Prey taken is often much smaller than the crocodile itself, and such prey can be overpowered and swallowed with ease. When it comes to larger prey, success depends on the crocodile's body power and weight to pull the prey item back into the water, where it is either drowned or killed by sudden thrashes of the head or by tearing it into pieces with the help of other crocodiles.
+
+Subadult and smaller adult Nile crocodiles use their bodies and tails to herd groups of fish toward a bank, and eat them with quick sideways jerks of their heads. Some crocodiles of the species may habitually use their tails to sweep terrestrial prey off balance, sometimes forcing the prey specimen into the water, where it can be more easily drowned. They also cooperate, blocking migrating fish by forming a semicircle across the river. The most dominant crocodile eats first. Their ability to lie concealed with most of their bodies under water, combined with their speed over short distances, makes them effective opportunistic hunters of larger prey. They grab such prey in their powerful jaws, drag it into the water, and hold it underneath until it drowns. They also scavenge or steal kills from other predators, such as lions and leopards (Panthera pardus). Groups of Nile crocodiles may travel hundreds of meters from a waterway to feast on a carcass. They also feed on dead hippopotamuses (Hippopotamus amphibius) as a group (sometimes including three or four dozen crocodiles), tolerating each other. Much of the food from crocodile stomachs may come from scavenging carrion, and the crocodiles could be viewed as performing a similar function at times as do vultures or hyenas on land. Once their prey is dead, they rip off and swallow chunks of flesh. When groups are sharing a kill, they use each other for leverage, biting down hard and then twisting their bodies to tear off large pieces of meat in a "death roll". They may also get the necessary leverage by lodging their prey under branches or stones, before rolling and ripping.The Nile crocodile possesses unique predation behavior characterized by the ability of preying both within water, where it is best adapted, and out of it, which often results in unpredictable attacks on almost any other animal up to twice its size. Most hunting on land is done at night by lying in ambush near forest trails or roadsides, up to 50 m (170 ft) from the water's edge. Since their speed and agility on land is rather outmatched by most terrestrial animals, they must use obscuring vegetation or terrain to have a chance of succeeding during land-based hunts. In one case, an adult crocodile charged from the water up a bank to kill a bushbuck (Tragelaphus scriptus) and instead of dragging it into the water, was observed to pull the kill further on land into the cover of the bush. Two subadult crocodiles were once seen carrying the carcass of a nyala (Tragelaphus angasii) across land in unison. In South Africa, a game warden far from water sources in a savannah-scrub area reported that he saw a crocodile jump up and grab a donkey by the neck and then drag the prey off. Small carnivores are readily taken opportunistically, including African clawless otters (Aonyx capensis)
+
+
+=== Interspecific predatory relationships ===
+Living in the rich biosphere of Africa south of the Sahara, the Nile crocodile may come into contact with other large predators. Its place in the ecosystems it inhabits is unique, as it is the only large tetrapod carnivore that spends the majority of its life in water and hunting prey associated with aquatic zones. Large mammalian predators in Africa are often social animals and obligated to feed almost exclusively on land. The Nile crocodile is a strong example of an apex predator. Outside water, crocodiles can meet competition from other dominant savannah predators, notably big cats, which in Africa are represented by lions, cheetahs, and leopards. In general, big cats and crocodiles have a relationship of mutual avoidance. Occasionally, if regular food becomes scarce, both lions and the crocodile will steal kills on land from each other and, depending on size, will be dominant over one another. Both species may be attracted to carrion, and may occasionally fight over both kills or carrion. Most conflicts over food occur near the water and can literally lead to a tug-of-war over a carcass that can end either way, although seldom is there any serious fighting or bloodshed between the large carnivores. Intimidation displays may also resolve these conflicts. However, when size differences are prominent, the predators may prey on each other.
+
+
+== Reproduction ==
+
+On average, sexual maturity is obtained from 12 to 16 years of age. For males, the onset of sexual maturity occurs when they are about 3.3 m (10 ft 10 in) long and mass of 155 kg (342 lb), being fairly consistent. On the other hand, that for females is rather more variable, and may be indicative of the health of a regional population based on size at sexual maturity. On average, according to Cott (1961), female sexual maturity occurs when they reach 2.2 to 3 m (7 ft 3 in to 9 ft 10 in) in length. Similarly, a wide range of studies from southern Africa found that the average length for females at the onset of sexual maturity was 2.33 m (7 ft 8 in). However, stunted sexual maturity appears to occur in populations at opposite extremes, both where crocodiles are thought to be overpopulated and where they are overly reduced to heavy hunting, sometimes with females laying eggs when they measure as small as 1.5 m (4 ft 11 in) although it is questionable whether such clutches would bear healthy hatchlings.According to Bourquin (2008), the average breeding female in southern Africa is between 3 and 3.6 m (9 ft 10 in and 11 ft 10 in). Earlier studies support that breeding is often inconsistent in females less than 3 m (9 ft 10 in) and clutch size is smaller, a female at 2.75 m (9 ft 0 in) reportedly never lays more than 35 eggs, while a female measuring 3.64 m (11 ft 11 in) can expect a clutch of up to 95 eggs. In "stunted" newly mature females from Lake Turkana measuring 1.83 m (6 ft 0 in), the average clutch size was only 15. Graham and Beard (1968) hypothesized that, while females do continue to grow as do males throughout life, that past a certain age and size that females much over 3.2 m (10 ft 6 in) in length in Lake Turkana no longer breed (supported by the physiology of the females examined here); however, subsequent studies in Botswana and South Africa have found evidence of nesting females at least 4.1 m (13 ft 5 in) in length. In the Olifants River in South Africa, rainfall influenced the size of nesting females as only larger females (greater than 3 m (9 ft 10 in)) nested during the driest years. Breeding females along the Olifants were overall larger than those in Zimbabwe. Most females nest only every two to three years while mature males may breed every year.During the mating season, males attract females by bellowing, slapping their snouts in the water, blowing water out of their noses, and making a variety of other noises. Among the larger males of a population, territorial clashes can lead to physical fighting between males especially if they are near the same size. Such clashes can be brutal affairs and can end in mortality but typically end with victor and loser still alive, the latter withdrawing into deep waters. Once a female has been attracted, the pair warble and rub the undersides of their jaws together. Compared to the tender behaviour of the female accepting the male, copulation is rather rough (even described as "rape"-like by Graham & Beard (1968)) in which the male often roars and pins the female underwater. Cott noted little detectable discrepancy in the mating habits of Nile crocodiles and American alligators. In some regions, males have reportedly mated with several females, perhaps any female that enters his claimed territory, though in most regions annual monogamy appears to be most common in this species.
+
+Females lay their eggs about one to two months after mating. The nesting season can fall in nearly every month of the year. In the northern extremes of the distribution (i.e. Somalia or Egypt), the nesting season is December through February while in the southern limits (i.e. South Africa or Tanzania) is in August through December. In crocodiles between these distributions egg-laying is in intermediate months, often focused between April and July. The dates correspond to about a month or two into the dry season within that given region. The benefits of this are presumably that nest flooding risk is considerably reduced at this time and the stage at which hatchlings begin their lives out of the egg falls roughly at the beginning of the rainy season, when water levels are still relatively low but insect prey is in recovery. Preferred nesting locations are sandy shores, dry stream beds, or riverbanks. The female digs a hole a few metres from the bank and up to 0.5 m (20 in) deep, and lays on average between 25 and 80 eggs. The number of eggs varies and depends partially on the size of the female. The most significant prerequisites to a nesting site are soil with the depth to permit the female to dig out the nest mound, shading to which mother can retire during the heat of the day and access to water. She finds a spot soft enough to allow her to dig a sideways slanted burrow. The mother Nile crocodile deposits the eggs in the terminal chamber and packs the sand or earth back over the nest pit. While, like all crocodilians, the Nile crocodile digs out a hole for a nest site, unlike most other modern crocodilians, female Nile crocodiles bury their eggs in sand or soil rather than incubate them in rotting vegetation. The female may urinate sporadically on the soil to keep it moist, which prevents soil from hardening excessively. After burying the eggs, the female then guards them for the three-month incubation period. Nests have been recorded seldom in concealed positions such as under a bush or in grasses, but normally in open spots on the bank. It is thought the Nile crocodile cannot nest under heavy forest cover as can two of the three other African crocodiles because they do not use rotting leaves (a very effective method of producing heat for the eggs) and thus require sunlight on sand or soil the surface of the egg chamber to provide the appropriate warmth for embryo development. In South Africa, the invasive plant Chromolaena odorata has recently exploded along banks traditionally used by crocodiles as nesting sites and caused nest failures by blocking sunlight over the nest chamber.When Nile crocodiles have been entirely free from disturbance in the past, they may nest gregariously with the nest lying so close together that after hatching time the rims of craters are almost contiguous. These communal nesting sites are not known to exist today, perhaps being most recently recorded at Ntoroko peninsula, Uganda where two such sites remaining until 1952. In one area, 17 craters were found in an area of 25 yd × 22 yd (75 ft × 66 ft), in another 24 in an area of 26 yd × 24 yd (78 ft × 72 ft). Communal nesting areas also reported from Lake Victoria (up until the 1930s) and also in the 20th century at Rahad River, Lake Turkana and Malawi. The behaviour of the female Nile crocodile is considered unpredictable and may be driven by the regional extent of prior human disturbance and human persecution rather than natural variability. In some areas, the mother crocodiles will only leave the nest if she needs to cool off (thermoregulation) by taking a quick dip or seeking out a patch of shade. Females will not leave nest site even if rocks are thrown at her back and several authors note her trance-like state while standing near nest, similar to that of crocodiles in aestivation but not like any other stage in their life-cycle. In such a trance, some mother Nile crocodiles may show no discernable reaction even if pelted with stones. At other times, the female will fiercely attack anything approaching their eggs, sometimes joined by another crocodile which may be the sire of the young. In other areas, the nesting female may disappear upon potential disturbance which may allow the presence of both the female and her buried nest to escape unwanted detection by predators. Despite the attentive care of both parents, the nests are often raided by humans and monitor lizards or other animals while she is temporarily absent.At a reported incubation period of about 90 days, the stage is notably shorter than that of the American alligator (110–120 days) but slightly longer than that of the mugger crocodile. Nile crocodiles have temperature-dependent sex determination (TSD), which means the sex of their hatchlings is determined not by genetics as is the case in mammals and birds, but by the average temperature during the middle third of their incubation period. If the temperature inside the nest is below 31.7 °C (89.1 °F), or above 34.5 °C (94.1 °F), the offspring will be female. Males can only be born if the temperature is within that narrow range. The hatchlings start to make a high-pitched chirping noise before hatching, which is the signal for the mother to rip open the nest. It is thought to be either difficult or impossible for hatchlings to escape the nest burrow without assistance, as the surface may become very heavy and packed above them. The mother crocodile may pick up the eggs in her mouth, and roll them between their tongue and the upper palate to help crack the shell and release her offspring. Once the eggs hatch, the female may lead the hatchlings to water, or even carry them there in her mouth, as female American alligators have been observed doing.
+
+Hatchling Nile crocodiles are between 280 and 300 mm (11 and 12 in) long at first and weigh around 70 g (2.5 oz). The hatchlings grow approximately that length each year for the first several years. The new mother will protect her offspring for up to two years, and if there are multiple nests in the same area, the mothers may form a crèche. During this time, the mothers may pick up their offspring either in their mouths or gular fold (throat pouch) to keep the babies safe. The mother will sometimes carry her young on her back to avoid natural predators of the small crocodiles, which can be surprisingly bold even with the mother around. Nile crocodiles of under two years are much more rarely observed than larger specimens, and more seldom seen than the same age young in several other types of crocodilian. Young crocodiles are shy and evasive due to the formidable array of predators that they must face in sub-Saharan Africa, spending little time sunning and moving about nocturnally whenever possible. Crocodiles two years old and younger may spend a surprising amount of time on land, as evidenced by the range of terrestrial insects found in their stomachs, and their lifestyle may resemble that of a semi-aquatic mid-sized lizard more so than the very aquatic lives of older crocodiles. At the end of the two years, the hatchlings will be about 1.2 m (3 ft 11 in) long, and will naturally depart the nest area, avoiding the territories of older and larger crocodiles. After this stage, crocodiles may loosely associate with similarly sized crocodiles and many enter feeding congregations of crocodiles once they attain 2 m (6 ft 7 in), at which size predators and cannibal crocodiles become much less of a concern. Crocodile longevity is not well established, but larger species like the Nile crocodile live longer, and may have a potential average life span of 70 to 100 years, though no crocodilian species commonly exceeds a lifespan of 50 to 60 years in captivity.

+
+=== Natural mortality of young Nile crocodiles ===
+An estimated 10% of eggs will survive to hatch and a mere 1% of young that hatch will successfully reach adulthood. The full range of causes for mortality of young Nile crocodiles is not well understood, as very young and small Nile crocodiles or well-concealed nests are only sporadically observed. Unseasonable flooding (during nesting which corresponds with the regional dry season) is not uncommon and has probably destroyed several nests, although statistical likelihood of such an event is not known. The only aspect of mortality in this age range that is well studied is predation and this is most likely the primary cause of death while the saurians are still diminutive. The single most virulent predator of nests is almost certainly the Nile monitor. This predator can destroy about 50% of studied Nile crocodile eggs on its own, often being successful (as are other nest predators) in light of the trance-like state that the mother crocodile enters while brooding or taking advantage of moments where she is distracted or needs to leave the nest. In comparison, perenties (Varanus giganteus) (the Australian ecological equivalent of the Nile monitor) succeeds in depredating about 90% of freshwater crocodile (Crocodylus johnsoni) eggs and about 25% of saltwater crocodile nests. Mammalian predators can take nearly as heavy of a toll, especially large mongooses such the Egyptian mongoose (Herpestes ichneumon) in the north and the water mongoose in the south of crocodile's range. Opportunistic mammals who attack Nile crocodile nests have included wild pigs, medium-sized wild cats and baboon troops. Like Nile monitors, mammalian predators probably locate crocodile nests by scent as the padded-down mound is easy to miss visually. Marabou storks sometimes follow monitors to pirate crocodile eggs for themselves to consume, although can also dig out nests on their own with their massive, awl-like bills if they can visually discern the nest mound.Predators of Nile crocodiles eggs have ranged from insects such as the red flour beetle (Tribolium castaneum) to predators as large and formidable as spotted hyenas (Crocuta crocuta). Unsurprisingly, once exposed to the elements as hatchlings, the young, small Nile crocodiles are even more vulnerable. Most of the predators of eggs also opportunistically eat young crocodiles, including monitors and marabous, plus almost all co-existing raptorial birds, including vultures, eagles, and large owls and buzzards. Many "large waders" are virulent predators of crocodile hatchlings, from dainty little egrets (Egretta garzetta) and compact hamerkops (Scopus umbretta) to towering saddle-billed storks (Ephippiorhynchus senegalensis), goliath herons and shoebills (Balaeniceps rex). Larger corvids and some non-wading water birds (i.e. pelicans) can also take some young Nile crocodiles. Mammalian carnivores take many hatchlings as well as large turtles and snakes, large predatory freshwater fish, such as the African tigerfish, the introduced largemouth bass, and possibly bull sharks, when they enter river systems. When crocodile nests are dug out and the young placed in water by the mother, in areas such as Royal Natal National Park predators can essentially enter a feeding frenzy. It may take a few years before predation is no longer a major cause of mortality for young crocodiles. African fish eagles can take crocodile hatchlings up to a few months of age and honey badgers can prey on yearlings. Once they reach their juvenile stage, large African rock pythons and big cats remain as the only predatory threat to young crocodiles. Perhaps no predator is more deadly to young Nile crocodiles than larger crocodiles of their own species, as, like most crocodilians, they are cannibalistic. This species may be particularly dangerous to their own kind considering their aggressive dispositions. While the mother crocodile will react aggressively toward potential predators and has been recorded chasing and occasionally catching and killing such interlopers into her range, due to the sheer number of animals who feed on baby crocodiles and the large number of hatchlings, she is more often unsuccessful at deflecting such predators.
+
+
+== Environmental status ==
+Conservation organizations have determined that the main threats to Nile crocodiles, in turn, are loss of habitat, pollution, hunting, and human activities such as accidental entanglement in fishing nets. Though the Nile crocodile has been hunted since ancient times, the advent of the readily available firearm made it much easier to kill these potentially dangerous reptiles. The species began to be hunted on a much larger scale from the 1940s to the 1960s, primarily for high-quality leather, although also for meat with its purported curative properties. The population was severely depleted, and the species faced extinction. National laws, and international trade regulations have resulted in a resurgence in many areas, and the species as a whole is no longer wholly threatened with extinction. The status of Nile crocodiles was variable based on the regional prosperity and extent of conserved wetlands by the 1970s. However, as is the case for many large animal species whether they are protected or not, persecution and poaching have continued apace and between the 1950s and 1980s, an estimated 3 million Nile crocodiles were slaughtered by humans for the leather trade. In Lake Sibaya, South Africa, it was determined that in the 21st century, persecution continues as the direct cause for the inability of Nile crocodiles to recover after the leather trade last century. Recovery for the species appears quite gradual and few areas have recovered to bear crocodile populations, i.e. largely insufficient to produce sustainable populations of young crocodiles, on par with times prior to the peak of leather trading. Crocodile 'protection programs' are artificial environments where crocodiles exist safely and without the threat of extermination from hunters.
+
+An estimated 250,000 to 500,000 individuals occur in the wild today. The IUCN Red List assesses the Nile crocodile as "Least Concern (LR/lc)". The Convention on International Trade in Endangered Species (CITES) lists the Nile crocodile under Appendix I (threatened with extinction) in most of its range; and under Appendix II (not threatened, but trade must be controlled) in the remainder, which either allows ranching or sets an annual quota of skins taken from the wild. The Nile crocodile is widely distributed, with strong, documented populations in many countries in eastern and southern Africa, including Somalia, Ethiopia, Kenya, Zambia and Zimbabwe. This species is farmed for its meat and leather in some parts of Africa. Successful sustainable-yield programs focused on ranching crocodiles for their skins have been successfully implemented in this area, and even countries with quotas are moving toward ranching. In 1993, 80,000 Nile crocodile skins were produced, the majority from ranches in Zimbabwe and South Africa. Crocodile farming is one of the few burgeoning industries in Zimbabwe. Unlike American alligator flesh, Nile crocodile meat is generally considered unappetizing although edible as tribes such as the Turkana may opportunistically feed on them. According to Graham and Beard (1968), Nile crocodile meat has an "indescribable" and unpleasant taste, greasy texture and a "repellent" smell.The conservation situation is more grim in Central and West Africa presumably for both the Nile and West African crocodiles. The crocodile population in this area is much more sparse, and has not been adequately surveyed. While the natural population in these areas may be lower due to a less-than-ideal environment and competition with sympatric slender-snouted and dwarf crocodiles, extirpation may be a serious threat in some of these areas. At some point in the 20th century, the Nile crocodile appeared to have been extirpated as a breeding species from Egypt, but has locally re-established in some areas such as the Aswan Dam. Additional factors are a loss of wetland habitats, which is addition to direct dredging, damming and irrigation by humans, has retracted in the east, south and north of the crocodile's range, possibly in correlation with global warming. Retraction of wetlands due both to direct habitat destruction by humans and environmental factor possibly related to global warming is perhaps linked to the extinction of Nile crocodiles in the last few centuries in Syria, Israel and Tunisia. In Lake St. Lucia, highly saline water has been pumped into the already brackish waters due to irrigation practices. Some deaths of crocodiles appeared to have been caused by this dangerous salinity, and this one-time stronghold for breeding crocodiles has experienced a major population decline. In yet another historic crocodile stronghold, the Olifants River, which flows through Kruger National Park, numerous crocodile deaths have been reported. These are officially due to unknown causes but analysis has indicated that environmental pollutants caused by humans, particularly the burgeoning coal industry, are the primary cause. Much of the contamination of crocodiles occurs when they consume fish themselves killed by pollutants. Additional ecological surveys and establishing management programs are necessary to resolve these questions.
+The Nile crocodile is the top predator in its environment, and is responsible for checking the population of mesopredator species, such as the barbel catfish and lungfish, that could overeat fish populations on which other species, including birds, rely. One of the fish predators seriously affected by the unchecked mesopredator fish populations (due again to crocodile declines) is humans, particularly with respect to tilapia, an important commercial fish that has declined due to excessive predation. The Nile crocodile also consumes dead animals that would otherwise pollute the waters.
+
+
+=== Attacks on humans ===
+
+Much of the hunting of and general animosity toward Nile crocodiles stems from their reputation as a man-eater, which is not entirely unjustified. Despite most attacks going unreported, the Nile crocodile along with the saltwater crocodile is estimated to kill hundreds (possibly thousands) of people each year, which is more than all other crocodilian species combined. While these species are much more aggressive toward people than other living crocodilians (as is statistically supported by estimated numbers of crocodile attacks), Nile crocodiles are not particularly more likely to behave aggressively to humans or regard humans as potential prey than saltwater crocodiles. However, unlike other "man-eating" crocodile species, including the saltwater crocodile, the Nile crocodile lives in close proximity to human populations through most of its range, so contact is more frequent. This combined with the species' large size creates a higher risk of attack. Crocodiles as small as 2.1 m (6 ft 11 in) are capable of overpowering and successfully preying on small apes and hominids, presumably including children and smaller adult humans, but a majority of fatal attacks on humans are by crocodiles reportedly exceeding 3 m (9 ft 10 in) in length.In studies preceding the slaughter of crocodiles for the leather trade, when there were believed to be many more Nile crocodiles, a roughly estimated 1,000 human fatalities per annum by Nile crocodiles were posited, with a roughly equal number of aborted attacks. A more contemporary study claimed the number of attacks by Nile crocodiles per year as 275 to 745, of which 63% are fatal, as opposed to an estimated 30 attacks per year by saltwater crocodiles, of which 50% are fatal. With the Nile crocodile and the saltwater crocodile, the mean size of crocodiles involved in non-fatal attacks was about 3 m (9 ft 10 in) as opposed to a reported range of 2.5–5 m (8 ft 2 in – 16 ft 5 in) or larger for crocodiles responsible for fatal attacks. The average estimated size of Nile crocodiles involved in fatal attacks is 3.5 m (11 ft 6 in). Since a majority of fatal attacks are believed to be predatory in nature, the Nile crocodile can be considered the most prolific predator of humans among wild animals. In comparison, lions, in the years from 1990 to 2006, were responsible for an estimated one-eighth as many fatal attacks on humans in Africa as were Nile crocodiles. Although Nile crocodiles are more than a dozen times more numerous than lions in the wild, probably fewer than a quarter of living Nile crocodiles are old and large enough to pose a danger to humans. Other wild animals responsible for more annual human mortalities either attack humans in self-defense, as do venomous snakes, or are deadly only as vectors of disease or infection, such as snails, rats and mosquitos.Regional reportage from numerous areas with large crocodile populations nearby indicate, per district or large village, that crocodiles often annually claim about a dozen or more lives per year. Miscellaneous examples of areas in the last few decades with a dozen or more fatal crocodile attacks annually include Korogwe District, Tanzania, Niassa Reserve, Mozambique and the area around Lower Zambezi National Park, Zambia. Despite historic claims that the victims of Nile crocodile attacks are usually women and children, there is no detectable trends in this regard and any human, regardless of age, gender, or size is potentially vulnerable.  Incautious human behavior is the primary drive behind crocodile attacks. Most fatal attacks occur when a person is standing a few feet away from water on a non-steep bank, is wading in shallow waters, is swimming or has limbs dangling over a boat or pier. Many victims are caught while crouching, and people in jobs that might require heavy usage of water, including laundry workers, fisherman, game wardens and regional guides, are more likely to be attacked. Many fisherman and other workers who are not poverty-stricken will go out of their way to avoid waterways known to harbor large crocodile populations.Most biologists who have engaged in months or even years of field work with Nile crocodiles, including Cott (1961), Graham and Beard (1968) and Guggisberg (1972), have found that with sufficient precautions, their own lives and the lives of their local guides were rarely, if ever, at risk in areas with many crocodiles. However, Guggisberg accumulated several earlier writings that noted the lack of fear of crocodiles among Africans, driven in part perhaps by poverty and superstition, that caused many observed cases of an "appalling" lack of caution within view of large crocodiles, as opposed to the presence of bold lions, which engendered an appropriate panic. Per Guggisberg, this disregard (essentially regarding the crocodile as a lowly creature and thus non-threatening to humans) may account for the higher frequency of deadly attacks by crocodiles than by large mammalian carnivores. Most locals are well aware of how to behave in crocodile-occupied areas, and some of the writings quoted by Guggisberg from the 19th and 20th century may need to be taken with a "grain of salt".

+The burrowing parrot (Cyanoliseus patagonus), also known as the burrowing parakeet or the Patagonian conure, is a species of parrot native to Argentina and Chile.  It belongs to the monotypic genus Cyanoliseus, with four subspecies that are currently recognized.
+The burrowing parrot is unmistakable with a distinctive white eye ring, white breast marking, olive green body colour, and brightly coloured underparts. Named for their nesting habits, burrowing parrots excavate elaborate burrows in cliff faces and ravines in order to rear their chicks. They inhabit dry, open country up to 2000 m in elevation. Once abundant across Argentina and Chile, burrowing parrot populations have been in decline due to exploitation and persecution.
+
+
+== Taxonomy, phylogeny and systematics ==
+
+The burrowing parrot was first described in 1818 by Louis Pierre Vieillot as Psittacus patagonus. The genus was later renamed Cyanoliseus by Charles Lucien Bonaparte in 1854.The burrowing parrot is the only member of the genus Cyanoliseus, making it monotypic. Together with other genera of long-tailed New World parrots, Cyanoliseus is a part of the Tribe Arini, which in turn is a part of the subfamily Arinae, or Neotropical parrots, in the family of true parrots, Psittacidae. The closest relative of the burrowing parrot is thought to be the Nanday parakeet.There are four recognized subspecies, however the subspecies C. p. conlara is considered doubtfully distinct:
+C. p. patagonus (Vieillot) is the nominate subspecies found in central to southeast Argentina, with some migrants reaching southern Uruguay
+C. p. andinus (Dabbene and Lillo) is found in northwest Argentina, from Salta to San Juan. Plumage is duller than the nominate C. p. patagonus, with much fainter markings. This population is estimated to be approximately 2000 individuals.
+C. p. conlara (Nores and Yzurieta) can be found in San Luis, between the ranges of C. p. patagonus and C. p. andinus, and is visually similar to C. p. patagonus except for a darker breast, suggesting that C. p. conlara may be a hybrid instead of a distinct subspecies
+C. p. bloxami (Olson), formerly C. p. byroni, also known as the Greater Patagonian Conure, is the Chilean sub-population. Formerly occurring from Atacama to Valdiva, now this subspecies is restricted to isolated populations in central Chile in O'Higgins, Maule and Atacama. Unlike the nominate subspecies, the white breast markings of this subspecies are prominent and extend across the whole breast, and the yellow underparts and red abdomen are much brighter. It is larger in size than C. p. patagonus at 315-390g. Populations are currently estimated at 5000-6000 individuals.Another subspecies, C. p. whitleyi (Kinnear), was described but has since been determined to be an aviary hybrid between a burrowing parrot and a species from the genus Aratinga or possibly Primolius.A study on mitochondrial DNA in burrowing parrots suggests that the species originated in Chile, the Argentinian populations arising during the Late Pleistocene from "a single migration event across the Andes, which gave rise to all extant Argentinean mitochondrial lineages". The Andes represent a strong geographical barrier, thus isolating the Chilean population, which were found to be genetically and phenotypically distinct from the Argentinian populations. This study found no support for C. p. conlara as a subspecies, and instead suggests a hybrid zone between the  C. p. patagonus and C. p. andinus ranges where C. p. conlara represents the hybrid phenotype.
+
+
+== Description ==
+Adults measure 39–52 cm in length, with a wingspan of 23–25 cm and a long, graduated tail that can range from 21 to 26 cm. Burrowing parrots are slightly sexually dimorphic, with males being slightly larger and weighing approximately 253-340 g, while females weigh 227-304 g, making it the largest member of the group of New World parakeet species commonly known as conures.The burrowing parrot is a distinctive parrot; it has a bare, white eye ring and post-ocular patch, its head and upper back are olive-brown, and its throat and breast are grey-brown with a whitish pectoral marking, which is variable and rarely extends across the whole breast. The lower thighs and the center of the abdomen are orange-red, and it is thought that the extent and hue of the red plumage indicates the quality of the individual as a breeding partner and parent. The lower back, upper thighs, rump, vent and flanks are yellow, and the wing coverts olive green. The tail is olive green with a blue caste when viewed from above and brown from below. The burrowing parrot has a grey bill and yellow-white iris with pink legs. Immature birds look like adults but with a horn coloured upper mandible patch and a pale grey iris.While both sexes look visually similar to the human eye, the burrowing parrot is sexually dichromatic. Males tend to have significantly redder and larger abdominal red patches, and both sexes look different under UV light, with males have brighter green feathers and females having brighter blue feathers.
+
+
+== Distribution and habitat ==
+The burrowing parrot can be found in much of Argentina, and there are isolated populations in central Chile. In the winter, birds in central and southern Argentina may migrate north as far as southern Uruguay, making them austral migrants, while Chilean birds migrate vertically down slope to avoid colder altitudes. Movements in the populations of northwestern Argentina are also known to occur according to food availability.The burrowing parrot prefers dry, open country, particularly in the vicinity of water courses, up to 2000 m in elevation. Habitats include montane grassy shrubland, Patagonian steppes, arid lowland, woodland savanna, and the plains of the Gran Chaco. They may also inhabit farmland and the edges of urban areas.
+
+
+== Behaviour and ecology ==
+
+
+=== Diet ===
+The diet of the burrowing parrot comprises seeds, berries, fruits, and possibly vegetable matter, and they can be seen feeding on the ground or in trees and shrubs. Their diet varies seasonally, with fruit consumption peaking during Argentina's summer (December–February), where one study found that fruit makes up 2% of their crop contents in November–December, 74% in January, 25% in February, 35%,in March and 8% in April. Specifically, burrowing parrots have been observed feeding on the fruit from various species such as the red crowberry (Empetrum rubrum), Chilean palo verde (Geoffroea decorticans), Lycium salsum, pepper trees (Schinus sp.), Prosopis sp., Discaria sp., as well as cacti. In the winter, the burrowing parrot feeds predominantly on seeds from cultivated crops and wild plants such as thistles, as well as the Patagonian oak (Nothofagus obliqua) and the Carboncillo (Cordia decandra) in the Chilean foothills.
+
+
+=== Reproduction ===
+Best known for its nesting habits, the burrowing parrot excavates industrious burrows in limestone or sandstone cliff faces, often in ravines. These burrows can be as much as 3 m deep into a cliff-face, connecting with other tunnels to create a labyrinth, ending in a nesting chamber. Breeding pairs will reuse burrows from previous years but may enlarge them. They nest in large colonies, some of the largest ever recorded for parrots, which is thought to reduce predation. The parrots tend to select larger, taller ravines, allowing for larger colonies and higher burrows and resulting in higher breeding success.In the absence of acceptable ravines or cliffs to use as nesting sites, burrowing parrots will use anthropogenic substrates such as quarries, wells and pits. Rarely, they have been known to nest in tree cavities.Studies have shown that burrowing parrots are both socially and genetically monogamous. The breeding season begins in September, and eggs are laid up to December, with two up to five eggs laid per clutch. The incubation period is 24–25  days, where the female is the sole incubator while the male provides for her. Eggs hatch asynchronously, and mortality is higher for fourth and fifth chicks in a clutch. Both parents care for the chicks. Chicks begin to fledge in late December until February, approximately eight weeks after hatching, and the fledglings depend on their parents for up to four months.
+
+
+=== Thermoregulation ===
+In order to cope with an unpredictable climate, burrowing parrots increase their body mass and decrease their basal metabolic rate (BMR) in the winter in order to conserve energy, insulate against cold ambient temperatures and to survive reductions in food availability, in concurrence with other birds found in the southern hemisphere.
+
+
+== Status and relationship to humans ==
+
+The burrowing parrot currently has a conservation status of least concern according to the IUCN Red List, however populations are currently declining, due to exploitation for the wildlife trade and persecution as a crop pest. In Chile, the burrowing parrot (specifically, the C. p. bloxami subspecies) is on the national vertebrate red list. It is currently listed under Appendix II of CITES, allowing for international trade. Due to their nesting habits, they are particularly vulnerable to human disturbances and habitat degradation.The burrowing parrot was officially named as a crop pest in Argentina in 1984, leading to increased persecution. Their status as a crop pest has excluded them protection under Argentina's ban on wildlife trade, however the province of Río Negro has deemed population reductions sufficient and banned hunting and trade of the burrowing parrot as of 2004. Studies have shown that the effects of crop predation by burrowing parrots is economically insignificant. Additionally, birds of the Chilean subspecies (C. p. bloxami) have been hunted for feast-day in Chile.The Mapuche people of the province of Neuquén in the Patagonian Andes celebrate the annual fledging of burrowing parrots with a festival.
+
+
+=== Aviculture ===
+The burrowing parrot, commonly called the Patagonian conure in aviculture, is a popular companion parrot. It is known for being playful, gentle and affectionate with humans, even cuddly when tame - it can also learn to talk and mimic sounds from its environment. As a large parakeet, it requires plenty of living space and the opportunity to fly on a regular basis in order to thrive. The maximum verified lifespan for this species in captivity is 19.5 years, however plausible claims of burrowing parrots living up to 34.1 years have also been reported.The subspecies typically found in aviculture is the nominate ssp., Cyanoliseus patagonus patagonus - also known as the lesser Patagonian conure. Tens of thousands of burrowing parakeets were previously removed from the wild and exported for the pet trade, however most birds available for purchase as pets are captive-bred at present.

Males tend to have significantly redder and larger abdominal red patches, and both sexes look different under UV light, with males have brighter green feathers and females having brighter blue feathers.
+
+
+== Distribution and habitat ==
+The burrowing parrot can be found in much of Argentina, and there are isolated populations in central Chile. In the winter, birds in central and southern Argentina may migrate north as far as southern Uruguay, making them austral migrants, while Chilean birds migrate vertically down slope to avoid colder altitudes. Movements in the populations of northwestern Argentina are also known to occur according to food availability.The burrowing parrot prefers dry, open country, particularly in the vicinity of water courses, up to 2000 m in elevation. Habitats include montane grassy shrubland, Patagonian steppes, arid lowland, woodland savanna, and the plains of the Gran Chaco. They may also inhabit farmland and the edges of urban areas.
+
+
+== Behaviour and ecology ==
+
+
+=== Diet ===
+The diet of the burrowing parrot comprises seeds, berries, fruits, and possibly vegetable matter, and they can be seen feeding on the ground or in trees and shrubs. Their diet varies seasonally, with fruit consumption peaking during Argentina's summer (December–February), where one study found that fruit makes up 2% of their crop contents in November–December, 74% in January, 25% in February, 35%,in March and 8% in April. Specifically, burrowing parrots have been observed feeding on the fruit from various species such as the red crowberry (Empetrum rubrum), Chilean palo verde (Geoffroea decorticans), Lycium salsum, pepper trees (Schinus sp.), Prosopis sp., Discaria sp., as well as cacti. In the winter, the burrowing parrot feeds predominantly on seeds from cultivated crops and wild plants such as thistles, as well as the Patagonian oak (Nothofagus obliqua) and the Carboncillo (Cordia decandra) in the Chilean foothills.
+
+
+=== Reproduction ===
+Best known for its nesting habits, the burrowing parrot excavates industrious burrows in limestone or sandstone cliff faces, often in ravines. These burrows can be as much as 3 m deep into a cliff-face, connecting with other tunnels to create a labyrinth, ending in a nesting chamber. Breeding pairs will reuse burrows from previous years but may enlarge them. They nest in large colonies, some of the largest ever recorded for parrots, which is thought to reduce predation. The parrots tend to select larger, taller ravines, allowing for larger colonies and higher burrows and resulting in higher breeding success.In the absence of acceptable ravines or cliffs to use as nesting sites, burrowing parrots will use anthropogenic substrates such as quarries, wells and pits. Rarely, they have been known to nest in tree cavities.Studies have shown that burrowing parrots are both socially and genetically monogamous. The breeding season begins in September, and eggs are laid up to December, with two up to five eggs laid per clutch. The incubation period is 24–25  days, where the female is the sole incubator while the male provides for her. Eggs hatch asynchronously, and mortality is higher for fourth and fifth chicks in a clutch. Both parents care for the chicks. Chicks begin to fledge in late December until February, approximately eight weeks after hatching, and the fledglings depend on their parents for up to four months.
+
+
+=== Thermoregulation ===
+In order to cope with an unpredictable climate, burrowing parrots increase their body mass and decrease their basal metabolic rate (BMR) in the winter in order to conserve energy, insulate against cold ambient temperatures and to survive reductions in food availability, in concurrence with other birds found in the southern hemisphere.
+
+
+== Status and relationship to humans ==
+
+The burrowing parrot currently has a conservation status of least concern according to the IUCN Red List, however populations are currently declining, due to exploitation for the wildlife trade and persecution as a crop pest. In Chile, the burrowing parrot (specifically, the C. p. bloxami subspecies) is on the national vertebrate red list. It is currently listed under Appendix II of CITES, allowing for international trade. Due to their nesting habits, they are particularly vulnerable to human disturbances and habitat degradation.The burrowing parrot was officially named as a crop pest in Argentina in 1984, leading to increased persecution. Their status as a crop pest has excluded them protection under Argentina's ban on wildlife trade, however the province of Río Negro has deemed population reductions sufficient and banned hunting and trade of the burrowing parrot as of 2004. Studies have shown that the effects of crop predation by burrowing parrots is economically insignificant. Additionally, birds of the Chilean subspecies (C. p. bloxami) have been hunted for feast-day in Chile.The Mapuche people of the province of Neuquén in the Patagonian Andes celebrate the annual fledging of burrowing parrots with a festival.
+
+
+=== Aviculture ===
+The burrowing parrot, commonly called the Patagonian conure in aviculture, is a popular companion parrot. It is known for being playful, gentle and affectionate with humans, even cuddly when tame - it can also learn to talk and mimic sounds from its environment. As a large parakeet, it requires plenty of living space and the opportunity to fly on a regular basis in order to thrive. The maximum verified lifespan for this species in captivity is 19.5 years, however plausible claims of burrowing parrots living up to 34.1 years have also been reported.The subspecies typically found in aviculture is the nominate ssp., Cyanoliseus patagonus patagonus - also known as the lesser Patagonian conure. Tens of thousands of burrowing parakeets were previously removed from the wild and exported for the pet trade, however most birds available for purchase as pets are captive-bred at present.

+The rhinoceros iguana (Cyclura cornuta) is an endangered species of iguana that is endemic to the Caribbean island of Hispaniola (shared by Haiti and the Dominican Republic) and its surrounding islands. A large lizard, they vary in length from 60 to 136 centimetres (24 to 54 in), and skin colours range from a steely grey to a dark green and even brown. Their name derives from the bony-plated pseudo-horn or outgrowth which resembles the horn of a rhinoceros on the iguana's snout. It is known to coexist with the Ricord's iguana (C. ricordii); the two species are the only taxa of rock iguana to do so.
+
+
+== Taxonomy ==
+The rhinoceros iguana is a species of lizard belonging to the genus Cyclura.   The rhinoceros iguana's specific name, cornuta, is the feminine form of the Latin adjective cornutus, meaning "horned" and refers to the horned projections on the snouts of males of the species.  The species was first identified by Pierre Joseph Bonnaterre in 1789.In addition to the nominate race (C. c. cornuta) found on Hispaniola, the other subspecies is the extinct Navassa Island iguana (C. c. onchiopsis). The Mona ground iguana (Cyclura stejnegeri) from Puerto Rico was originally thought to be a subspecies (and still is by some taxonomists), as Cyclura cornuta stejnegeri.
+
+
+== Anatomy and morphology ==
+The rhinoceros iguana, like other members of the genus Cyclura, is a large-bodied, heavy-headed lizard with strong legs and a vertically flattened tail. A crest of pointed horned scales extends from the nape of their neck to the tip of their tail. Their color is a uniform gray to brown drab. Most adults weigh 4.56 to 9 kilograms (10.1 to 19.8 lb). Like all reptiles, rhinoceros iguanas are cold-blooded, meaning they need external sources to heat themselves; they move as the sun shifts in order to get an optimal internal temperature.These iguanas are characterized by the growth of bony prominent tubercles on their snouts which resemble horns. Males possess an adipose pad in the form of a helmet on the occipital region of the head, and a large dewlap. This species, like other species of Cyclura, is sexually dimorphic; males are larger than females, and have more prominent dorsal crests and "horns" in addition to large femoral pores on their thighs, which are used to release pheromones.
+
+
+== Distribution and habitat ==
+
+Ranging throughout Hispaniola (in both Haiti and the Dominican Republic), rhinoceros iguana populations are stable only on Isla Beata, and the extreme of the Barahona Peninsula, inside Jaragua National Park. There are moderately dense populations in the southeastern region of Haiti and its offshore islands, including the brackish lake of Étang Saumâtre, as well as the Dominican hypersaline Lake Enriquillo and its lake island, Isla Cabritos. Populations in Haiti are even more endangered due to deforestation, poaching for bushmeat, and human clearing practices. In general, the iguanas are found most abundantly in (although not restricted to) scrub woodland in Hispaniolan dry forests, which are characterized by xeric, rocky habitats of eroded limestone in coastal terraces and lowlands of the mainland, and several offshore islands and small cays in a variety of subtropical life zones and habitat types. The biome that the rhinoceros iguanas live in are ones that receive very little rain with little trees and shrubs. This species has been known to exhibit phenotypic plasticity like other iguanas. While historically present near coastlines, human activity and introduced predators have forced rhinoceros iguanas inland.An individual was photographed on May 4, 2008 on Limbe Island in northern Haiti. It had been caught by a group of fishermen from Bas-Limbe, Bord de Mer village. The rhinoceros iguanas caught on Limbe Island are illegally eaten by the local population. This sighting represents a new area previously not thought to be in the range of C. cornata.
+Aside from Hispaniola and its surrounding islands, the rhinoceros iguana was previously found on Navassa Island (with an endemic subspecies: C. c. onchiopsis), but was extirpated there.
+
+
+== Behaviour ==
+Rhinoceros iguanas, like most members of Cyclura, are usually docile and well-tempered. Although quick to flee when attacked or threatened, they will aggressively attack by biting and repeatedly striking with their thick tail if cornered.
+
+
+== Diet ==
+
+The rhinoceros iguana, like most Cyclura species, is primarily herbivorous, consuming leaves, flowers, berries, and fruits from different plant species. A study in 2000 by Dr Allison Alberts of the San Diego Zoo revealed that seeds passing through the digestive tracts of Cyclura species germinate more rapidly than those that do not. These seeds in the fruits consumed by cycluras have an adaptive advantage by sprouting before the end of very short rainy seasons. The rhinoceros iguana is also an important means of distributing these seeds to new areas (particularly when females migrate to nesting sites) and, as the largest native herbivores of their island's ecosystem, they are essential for maintaining the balance between climate and vegetation. Rhinoceros iguanas do appear to be opportunistic carnivores, as individual animals have been observed eating small lizards, snakes, and insects.
+
+
+== Ecology ==
+The rhinoceros iguana's only confirmed native predator is the Hispaniola racer (Haitiophis anomalus), a large snake which has been recorded to give chase to juvenile iguanas, as well as wait for them outside the exit holes of their burrow. However, most predation of iguanas comes from invasive species like feral dogs (Canis familiaris), feral cats (Felis catus), small Indian mongooses (Urva auropunctata), and feral pigs (Sus domesticus), which all feed on eggs, adults, and juveniles.
+
+
+== Mating and reproduction ==
+Male rhinoceros iguanas, unlike other members of the genus Cyclura, reach sexual maturity at four to five years of age. Females become sexually mature at two to three years of age. Male rhinoceros iguanas are territorial and the most aggressive males will have the largest range of territory. Mating takes place at the beginning of, or just prior to, the first rainy season of the year (May to June) and lasts for two to three weeks. Females lay from 2 to 34 eggs, with an average clutch size of 17, within 40 days. Females guard their nests for several days after laying their eggs, and incubation lasts approximately 85 days.Notably, despite rhinoceros iguanas exhibiting some sexual dimorphism in size and horn development, they exhibit comparatively less sexual dimorphism than most other iguanas. Both male and female rhinoceros iguanas lack prominent mid-dorsal spines on their neck, which are typically very large in male iguanas of other species, both have well-developed dewlaps, and both develop horns. By contrast, in many other animals that exhibit horns such as ungulates or rhinoceros beetles, horns are often only present in males. Rhinoceros iguanas are also reported to show less dimorphism in size than other iguana species. This reduced dimorphism has been suggested to be due to intense female-female competition in rhinoceros iguanas, given the scarcity of nesting sites in their island environment, and females will use their horns to fight with one another over access to nesting sites much as males fight for access to females. Similar female-female combat over nesting sites has been documented in other island iguanas such as the marine iguana.
+
+
+== Conservation ==
+
+Although rhinoceros iguanas are the most common species of Cyclura kept in captivity, approximately 10,000-16,000 iguanas remain in the wild. A successful breeding program existed at the Parque Zoológico Nacional of the Dominican Republic (ZooDom) from 1974 to 1994, with an average of 100 babies hatching annually. These efforts included reintroductions of captive-bred "head-started" young to several protected areas in the southwest Dominican Republic, in order to reduce the odds of predation by snakes and introduced carnivorans, such as mongooses or feral cats and dogs. The program has not continued since 1995, due to an administrative change at the zoo. International trade in the species is regulated under the Appendix I of the Convention on International Trade in Endangered Species. Illegal logging, competition from domestic grazers (cows, pigs, goats), predation on young by invasive species, limestone mining, harvesting for the pet trade, hunting for bushmeat, pollution, and wildfires are all manmade threats to the rhinoceros iguana's survival.
+
+
+== Captivity ==
+
+The rhinoceros iguana is well established in captivity, both in public and private collections. As of 2007, rhinoceros iguanas were present in captivity throughout the United States (total 39 males, 32 females, and 36 undetermined individuals) at 20 zoological institutions, with an additional 533 animals of unassigned subspecies, reported by seven American Zoological and Aquarium Association institutions. The actual number may be much higher, considering animals kept at European and Asian zoos, and the amount kept as pets in private collections. As a result, the demand for wild-caught animals to supply zoos and the pet trade has been reduced.

+The mute swan (Cygnus olor) is a species of swan and a member of the waterfowl family Anatidae. It is native to much of Eurosiberia, and (as a rare winter visitor) the far north of Africa. It is an introduced species in North America, home to the largest populations outside of its native range, with additional smaller introductions in Australasia and southern Africa. The name 'mute' derives from it being less vocal than other swan species. Measuring 125 to 160 cm (49 to 63 in) in length, this large swan is wholly white in plumage with an orange beak bordered with black. It is recognizable by its pronounced knob atop the beak, which is larger in males.
+
+
+== Taxonomy ==
+The mute swan was first formally described by the German naturalist Johann Friedrich Gmelin as Anas olor in 1789, and was transferred by Johann Matthäus Bechstein to the new genus Cygnus in 1803. Both cygnus and olor mean "swan" in Latin; cygnus is a variant form of cycnus, a borrowing from Greek κύκνος kyknos, a word of the same meaning.Despite its Eurasian origin, its closest relatives are the black swan of Australia and the black-necked swan of South America, not the other Northern Hemisphere swans of the genus Cygnus. The species is monotypic, with no living subspecies.
+
+
+== Evolution ==
+Mute swan subfossils, 6,000 years old, have been found in post-glacial peat beds of East Anglia, Great Britain. They have been recorded from Ireland east to Portugal and Italy, and from France, 13,000 BP (Desbrosse and Mourer-Chauvire 1972–1973). The paleosubspecies. Cygnus olor bergmanni, which differed only in size from the living bird, is known from fossils found in Azerbaijan. A related paleospecies recorded from fossils and subfossils is the Giant swan, Cygnus falconeri, a flightless species which lived on the islands of Malta and Sicily during the Middle Pleistocene.
+Fossils of swan ancestors more distantly allied to the mute swan have been found in four U.S. states: California, Arizona, Idaho and Oregon. The timeline runs from the Miocene to the late Pleistocene, or 10,000 BP. The latest find was in Anza Borrego Desert, a state park in California. Fossils from the Pleistocene include Cygnus paloregonus from Fossil Lake, Oregon, Froman's Ferry, Idaho, and Arizona, referred to by Howard in The Waterfowl of the World as "probably the mute type swan".
+
+
+== Description ==
+Adults of this large swan typically range from 140 to 160 cm (55 to 63 in) long, although can range in extreme cases from 125 to 170 cm (49 to 67 in), with a 200 to 240 cm (79 to 94 in) wingspan. Males are larger than females and have a larger knob on their bill. On average, this is the second largest waterfowl species after the trumpeter swan, although male mute swans can easily match or even exceed a male trumpeter in mass. Among standard measurements of the mute swan, the wing chord measures 53–62.3 cm (20.9–24.5 in), the tarsus is 10–11.8 cm (3.9–4.6 in) and the bill is 6.9–9 cm (2.7–3.5 in). The plumage is white, while the legs are dark grey. The beak of the mute swan is bright orange, with black around the nostrils and a black nail.
+The mute swan is one of the heaviest flying birds. In several studies from Great Britain, males (known as cobs) were found to average from about 10.6 to 11.87 kg (23.4 to 26.2 lb), with a weight range of 9.2–14.3 kg (20–32 lb) while the slightly smaller females (known as pens) averaged about 8.5 to 9.67 kg (18.7 to 21.3 lb), with a weight range of 7.6–10.6 kg (17–23 lb). While the top normal weight for a big cob is roughly 15 kg (33 lb), one unusually big Polish cob weighed almost 23 kg (51 lb) and this counts as the largest weight ever verified for a flying bird, although it has been questioned whether this heavyweight could still take flight.Young birds, called cygnets, are not the bright white of mature adults, and their bill is dull greyish-black, not orange, for the first year. The down may range from pure white to grey to buff, with grey/buff the most common. The white cygnets have a leucistic gene. Cygnets grow quickly, reaching a size close to their adult size in approximately three months after hatching. Cygnets typically retain their grey feathers until they are at least one year old, with the down on their wings having been replaced by flight feathers earlier that year.
+All mute swans are white at maturity, though the feathers (particularly on the head and neck) are often stained orange-brown by iron and tannins in the water.
+
+
+=== Polish swan ===
+
+The colour morph C. o. morpha immutabilis (immūtābilis is Latin for "immutable, unchangeable, unalterable"), also known as the "Polish swan", has pinkish (not dark grey) legs and dull white cygnets; as with white domestic geese, it is found only in populations with a history of domestication. Polish swans carry a copy of a gene responsible for leucism.
+
+
+== Behaviour ==
+
+Mute swans nest on large mounds that they build with waterside vegetation in shallow water on islands in the middle or at the very edge of a lake. They are monogamous and often reuse the same nest each year, restoring or rebuilding it as needed. Male and female swans share the care of the nest, and once the cygnets are fledged it is not uncommon to see whole families looking for food. They feed on a wide range of vegetation, both submerged aquatic plants which they reach with their long necks, and by grazing on land. The food commonly includes agricultural crop plants such as oilseed rape and wheat, and feeding flocks in the winter may cause significant crop damage, often as much through trampling with their large webbed feet, as through direct consumption. It will also feed on small proportions of aquatic insects, fish and frogs.Unlike black swans, mute swans are usually strongly territorial with just a single pair on smaller lakes, though in a few locations where a large area of suitable feeding habitat is found they can be colonial. The largest colonies have over 100 pairs, such as at the colony at Abbotsbury Swannery in southern England, and at the southern tip of Öland Island, Ottenby Preserve, in the coastal waters of the Baltic Sea, and can have nests spaced as little as 2 m (7 ft) apart. Non-mated juveniles up to 3–4 years old commonly form larger flocks, which can total several hundred birds, often at regular traditional sites. A notable flock of non-breeding birds is found on the River Tweed estuary at Berwick-upon-Tweed in northeastern England, with a maximum count of 787 birds. A large population exists near the Swan Lifeline Station in Windsor, and live on the Thames in the shadow of Windsor Castle. Once the adults are mated they seek out their own territories and often live close to ducks and gulls, which may take advantage of the swan's ability to reach deep water weeds, which tend to spread out on the water surface.The mute swan is less vocal than the noisy whooper and Bewick's swans; they do, however, make a variety of sounds, often described as "grunting, hoarse whistling, and snorting noises." During a courtship display, mute swans utter a rhythmic song. The song help synchronize the movements of their heads and necks. It could technically be employed to distinguish a bonded couple from two dating swans, as the rhythm of the song typically fails to match the pace of the head movements in two dating swans. Mute swans usually hiss at competitors or intruders trying to enter their territory. The most familiar sound associated with mute swans is the vibrant throbbing of the wings in flight which is unique to the species, and can be heard from a range of 1 to 2 km (0.6 to 1 mi), indicating its value as a contact sound between birds in flight. Cygnets are especially vocal, and communicate through a variety of whistling and chirping sounds when content, as well as a harsh squawking noise when distressed or lost.
+
+Mute swans can be very aggressive in defence of their nests and are highly protective of their mate and offspring. Most defensive acts from a mute swan begin with a loud hiss and, if this is not sufficient to drive off the predator or intruder, are followed by a physical attack. Swans attack by striking at the threat with bony spurs in their wings, accompanied by biting with their large bill, while smaller waterbirds such as ducks are normally grabbed with the swan's bill and dragged or thrown clear of the swan and its offspring. The wings of the swan are very powerful, though not strong enough to break an adult man's leg, as is commonly misquoted. Large waterfowl, such as Canada geese, (more likely out of competition than in response to potential predation) may be aggressively driven off, and mute swans regularly attack people who enter their territory.The cob is responsible for defending the cygnets while on the water, and will sometimes attack small watercraft, such as canoes, that it feels are a threat to its young. The cob will additionally try to chase the predator out of his family territory, and will keep animals such as foxes and raptors at bay. In New York (outside its native range), the most common predators of cygnets are common snapping turtles. Healthy adults are rarely preyed upon, though canids such as coyotes, felids such as lynx, and bears can pose a threat to infirm ones (healthy adults can usually swim away from danger and nest defense is usually successful.) and there are a few cases of healthy adults falling prey to golden eagles. In England, there has been an increased rate of attacks on swans by out-of-control dogs, especially in parks where the birds are less territorial. This is considered criminal in British law, and the birds are placed under the highest protection due to their association with the monarch. Mute swans will readily attack dogs to protect themselves and their cygnets from an attack, and an adult swan is capable of overwhelming and drowning even large dog breeds.The familiar pose with neck curved back and wings half raised, known as busking, is a threat display. Both feet are paddled in unison during this display, resulting in more jerky movement. The swans may also use the busking posture for wind-assisted transportation over several hundred meters, so-called windsurfing.Like other swans, mute swans are known for their ability to grieve for a lost or dead mate or cygnet. Swans will go through a mourning process, and in the case of the loss of their mate, may either stay where its counterpart lived, or fly off to join a flock. Should one of the pair die while there are cygnets present, the remaining parent will take up their partner's duties in raising the clutch.
+
+
+== Breeding ==
+
+Mute swans lay from 4 to 10 eggs. The female broods for around 36 days, with cygnets normally hatching between the months of May and July. The young swans do not achieve the ability to fly before about 120 to 150 days old. This limits the distribution of the species at the northern edge of its range as the cygnets need to learn to fly before the ponds and lakes freeze over.
+
+
+== Distribution and habitat ==
+The mute swan is found naturally mainly in temperate areas of Europe then across the Palearctic as far east as Primorsky Krai, near Sidemi.It is partially migratory throughout northern latitudes in Europe and Asia, as far south as North Africa and the Mediterranean. It is known and recorded to have nested in Iceland and is a vagrant to that area as well as to Bermuda, according to the UN Environment Programme chart of international status chart of bird species, which places it in 70 countries, breeding in 49 countries, and vagrant in 16 countries. While most of the current population in Japan is introduced, mute swans are depicted on scrolls more than 1,000 years old, and wild birds from the mainland Asian population still occur rarely in winter. Natural migrants to Japan usually occur along with whooper and sometimes Bewick's swans.The mute swan is protected in most of its range, but this has not prevented illegal hunting and poaching. It is often kept in captivity outside its natural range, as a decoration for parks and ponds, and escapes have happened. The descendants of such birds have become naturalised in the eastern United States and Great Lakes, much as the Canada goose has done in Europe.
+
+
+=== World population ===
+
+
+==== Native populations ====
+
+The total native population of mute swans is about 500,000 birds at the end of the breeding season (adults plus young), of which up to 350,000 are in Russia. The largest single breeding concentration is 11,000 pairs in the Volga Delta.The population in the United Kingdom is about 22,000 birds as of the 2006–2007 winter, a slight decline from the peak of about 26,000–27,000 birds in 1990. This includes about 5,300 breeding pairs, the remainder being immatures. Other significant populations in Europe include 6,800–8,300 breeding pairs in Germany, 4,500 pairs in Denmark, 4,000–4,200 pairs in Poland, 3,000–4,000 pairs in the Netherlands, about 2,500 pairs in Ireland, and 1,200–1,700 pairs in Ukraine.For many centuries, mute swans in Great Britain were domesticated for food, with individuals being marked by nicks on their webs (feet) or beaks to indicate ownership. These marks were registered with the Crown and a Royal Swanherd was appointed. Any birds not so marked became Crown property, hence the swan becoming known as the "Royal Bird". It is quite possible that this domestication saved the mute swan from extirpation through overhunting in Great Britain.Populations in western Europe were largely exterminated by hunting pressure in the 13th–19th centuries, with the exception of semi-domesticated birds maintained as poultry by large landowners. Better protection in the late 19th and early 20th centuries allowed birds to return to most or all of their former range. More recently in the period from about 1960 up to the early 1980s, numbers declined significantly again in many areas in England, primarily due to lead poisoning from birds swallowing lead shot from shooting and discarded fishing weights made from lead. After lead weights and shot were mostly replaced by other less toxic alternatives, mute swan numbers increased again rapidly.
+
+
+==== Introduced populations ====
+Since being introduced into North America, the mute swan has increased greatly in number to the extent that it is considered as an invasive species there. Populations introduced into other areas remain small, with around 200 in Japan, fewer than 200 in New Zealand and Australia, and about 120 in South Africa.
+
+
+===== North America =====
+The mute swan was introduced to North America in the late 19th century. Recently, it has been widely viewed as an invasive species because of its rapidly increasing numbers and its adverse effects on other waterfowl and native ecosystems. For example, a study of population sizes in the lower Great Lakes from 1971 to 2000 found that mute swan numbers were increasing at an average rate of at least 10% per year, doubling the population every seven to eight years. Several studies have concluded that mute swans severely reduce densities of submerged vegetation where they occur.In 2003, the U.S. Fish and Wildlife Service proposed to "minimize environmental damages attributed to Mute Swans" by reducing their numbers in the Atlantic Flyway to pre-1986 levels, a 67% reduction at the time. According to a report published in the Federal Register of 2003 the proposal was supported by all thirteen state wildlife agencies which submitted comments, as well as by 43 bird conservation, wildlife conservation and wildlife management organisations. Ten animal rights organisations and the vast majority of comments from individuals were opposed. At this time mute swans were protected under the Migratory Bird Treaty Act due to a court order, but in 2005 the United States Department of the Interior officially declared them a non-native, unprotected species. Mute swans are protected in some areas of the U.S. by local laws as, for example, in Connecticut.The status of the mute swan as an introduced species in North America is disputed by the interest group "Save the Mute Swans". They assert that mute swans are native in the region and therefore deserving of protection. They claim that mute swans had origins from Russia and cite historical sightings and fossil records. These claims have been rejected as specious by the U.S. Department of the Interior.
+
+
+===== Oceania =====
+The mute swan had absolute protection in New Zealand under the Wildlife Act 1953, but this was changed in June 2010 to a lower level of protection. It still has protection, but is now allowed to be killed or held in captivity at the discretion of the Minister of Conservation.A small feral population exists in the vicinity of Perth, Australia; however, it is believed to number less than 100 individuals.
+
+
+== In popular culture ==
+
+The mute swan has been the national bird of Denmark since 1984. Prior to that, the skylark was considered Denmark's national bird (since 1960).The fairy tale "The Ugly Duckling" by Hans Christian Andersen tells the story of a cygnet ostracised by his fellow barnyard fowl because of his perceived unattractiveness. To his delight (and to the surprise of others), he matures into a graceful swan, the most beautiful bird of all.Today, the British Monarch retains the right to ownership of all unmarked mute swans in open water, but Queen Elizabeth II exercised her ownership only on certain stretches of the Thames and its surrounding tributaries. This ownership is shared with the Vintners' and Dyers' Companies, who were granted rights of ownership by the Crown in the 15th century.The mute swans in the moat at the Bishops Palace at Wells Cathedral in Wells, England have for centuries been trained to ring bells via strings attached to them to beg for food. Two swans are still able to ring for lunch.The pair of swans in the Boston Public Garden are named Romeo and Juliet after the Shakespearean couple; however, it was found that both of them are females.

+The laughing kookaburra (Dacelo novaeguineae) is a bird in the kingfisher subfamily Halcyoninae. It is a large robust kingfisher with a whitish head and a brown eye-stripe. The upperparts are mostly dark brown but there is a mottled light-blue patch on the wing coverts. The underparts are cream-white and the tail is barred with rufous and black. The plumage of the male and female birds is similar. The territorial call is a distinctive laugh that is often delivered by several birds at the same time, and is widely used as a stock sound effect in situations that involve a jungle setting.The laughing kookaburra is native to eastern mainland Australia, but has also been introduced to parts of New Zealand, Tasmania, and Western Australia. It occupies dry eucalypt forest, woodland, city parks and gardens. This species is sedentary and occupies the same territory throughout the year. It is monogamous, retaining the same partner for life. A breeding pair can be accompanied by up to five fully grown non-breeding offspring from previous years that help the parents defend their territory and raise their young. The laughing kookaburra generally breeds in unlined tree holes or in excavated holes in arboreal termite nests. The usual clutch is three white eggs. The parents and the helpers incubate the eggs and feed the chicks. The youngest of the three nestlings or chicks is often killed by the older siblings. When the chicks fledge they continue to be fed by the group for six to ten weeks until they are able to forage independently.A predator of a wide variety of small animals, the laughing kookaburra typically waits perched on a branch until it sees an animal on the ground and then flies down and pounces on its prey. Its diet includes lizards, insects, worms, snakes, mice and it is known to take goldfish out of garden ponds.
+The International Union for Conservation of Nature (IUCN) has classed the laughing kookaburra as a species of least concern as it has a large range and population, with no widespread threats.
+
+
+== Taxonomy ==
+The laughing kookaburra was first described and illustrated (in black and white) by the French naturalist and explorer Pierre Sonnerat in his Voyage à la nouvelle Guinée, which was published in 1776. He claimed to have seen the bird in New Guinea. In fact Sonnerat never visited New Guinea and the laughing kookaburra does not occur there. He probably obtained a preserved specimen from one of the naturalists who accompanied Captain James Cook to the east coast of Australia. Edme-Louis Daubenton and François-Nicolas Martinet included a coloured plate of the laughing kookaburra based on Sonnerat's specimen in their Planches enluminées d'histoire naturelle. The plate has the legend in French "Martin-pecheur, de la Nouvelle Guinée" (Kingfisher from New Guinea).In 1783, the French naturalist Johann Hermann provided a formal description of the species based on the coloured plate by Daubenton and Martinet. He gave it the scientific name Alcedo novæ Guineæ. The current genus Dacelo was introduced in 1815 by the English zoologist William Elford Leach, and is an anagram of Alcedo, the Latin word for a kingfisher. The specific epithet novaeguineae combines the Latin novus for new with Guinea, based on the erroneous belief that the specimen had originated from New Guinea. For many years it was believed that the earliest description was by the Dutch naturalist Pieter Boddaert and his scientific name Dacelo gigas was used in the scientific literature, but in 1926 the Australian ornithologist Gregory Mathews showed that a description by Hermann had been published earlier in the same year, 1783, and thus had precedence.  The inaccurate impression of geographic distribution given by the name in current usage had not by 1977 been considered an important enough matter to force a change in favor of D. gigas.In the 19th century this species was commonly called the "laughing jackass", a name first recorded (as Laughing Jack-Ass) in An Account of the English Colony in New South Wales by David Collins which was published in 1798. In 1858 the ornithologist John Gould used "great brown kingfisher", a name that had been coined by John Latham in 1782. Another popular name was "laughing kingfisher". The names in several Australian indigenous languages were listed by European authors including Go-gan-ne-gine by Collins in 1798, Cuck'anda by René Lesson in 1828 and Gogera or Gogobera by George Bennett in 1834. In the early years of the 20th century "kookaburra" was included as an alternative name in ornithological publications, but it was not until 1926 in the second edition of the Official Checklist of Birds of Australia that the Royal Australasian Ornithologists Union officially adopted the name "laughing kookaburra". The name comes from Wiradjuri, an endangered Aboriginal language.The genus Dacelo contains four kookaburra species of which the rufous-bellied kookaburra and the spangled kookaburra are restricted to New Guinea and islands in the Torres Straits. The blue-winged kookaburra and the laughing kookaburra are both widespread in Australia.Two subspecies are recognised:
+D. n. novaeguineae (Hermann, 1783) – the nominate subspecies, east Australia, Tasmania and introduced into southwest Australia
+D. n. minor Robinson, 1900 – Cape York Peninsula south to Cooktown
+
+
+== Description ==
+
+The laughing kookaburra is the largest species of kingfisher, outsizing even the giant kingfisher in body mass. It is a stout, stocky bird 41–47 cm (16–19 in) in length, with a large head, prominent brown eyes, and a long and robust bill. The sexes are very similar, although the female is usually larger and has less blue to the rump than the male. The male weighs 196–450 g (6.9–15.9 oz), mean 307 g (10.8 oz) and the female 190–465 g (6.7–16.4 oz), mean 352 g (12.4 oz). They have a white or cream-coloured body and head with a dark brown stripe across each eye and more faintly over the top of the head. The wings and back are brown with sky blue spots on the shoulders. The tail is rusty reddish-orange with dark brown bars and white tips on the feathers. The heavy bill is black on top and bone-coloured on the bottom. The subspecies D. n. minor has a similar plumage to the nominate but is smaller in size.The laughing kookaburra can be distinguished from the similarly sized blue-winged kookaburra by its dark eye, dark eye-stripe, shorter bill and the smaller and duller blue areas on the wing and rump. Male blue-winged kookaburras also differ in having a barred blue and black tail.
+
+
+=== Call ===
+
+The name "laughing kookaburra" refers to the bird's "laugh", which it uses to establish territory among family groups. It can be heard at any time of day, but most frequently at dawn and dusk.This species possesses a tracheo-bronchial syrinx, which creates two sources of vibrations so it can produce two frequencies at the same time with multiple harmonics. The laughing kookaburras call is made through a complex sound production system, by forcing air from the lungs into the bronchial tubes. While the structure for producing calls is present from an early age, the kookaburra’s song is a learned behavior. The breeding pair within a riot of kookaburra teach the fledglings to produce the signature laughing call after the young have left the nest. The adult male will sing a short portion of the call while the offspring mimics this call, usually unsuccessfully. The singing lessons tend to last two weeks before the fledgling can properly sing and take part in crepuscular choral songs. Once mastered, the young can join in crepuscular chorus songs that aid in establishing territory.
+
+One bird starts with a low, hiccuping chuckle, then throws its head back in raucous laughter: often several others join in. If a rival tribe is within earshot and replies, the whole family soon gathers to fill the bush with ringing laughter. The laughing chorus has 5 variable elements: 1. "Kooa"; 2. "Cackle"; 3. "Rolling", a rapidly repeated "oo-oo-oo"; 4. Loud "Ha-ha"; followed by 5. Male's call of "Go-go" or female's call of "Gurgle".  Hearing kookaburras in full voice is one of the more extraordinary experiences of the Australian bush, something even locals cannot ignore; some visitors, unless forewarned, may find their calls startling.
+Those calls are produced to attract/guard mates, establish and maintain the social hierarchy, and declare and defend a territory, as their calls are more often correlated with aggressiveness. Calls are utilized as neighbor/kin recognition to exhibit that groups are still inhabiting a territory. These calls also demonstrate to receivers that highly coordinated groups are of better quality and health. Acoustic communication between laughing kookaburras increases 2–3 months before the breeding season, September to January, because male aggression also increases.The duetting call requires higher levels of cooperation within the group. The coordination of calls amongst kookaburras has been hypothesized to strengthen the main long-term pair bond and may have evolved as a mechanism to solidify the group’s bonds since it is energetically costly to learn a new song. Neighboring groups exhibit degrees of cooperation as well since chorus songs between neighbors are delivered without any overlap, alternating between groups.
+
+
+==== Other forms of acoustic communication ====
+Squawking is another common form of acoustic communication in D. novaeguineae that is used in a slew of different contexts. Laughing kookaburras have been noted to squawk when nesting, exhibiting submissive behavior, and when fledglings are waiting to be fed. Laughing kookaburras have a greater repertoire of calls than other kookaburra species like the Blue-winged kookaburra (Dacelo leachii) that produces two simple types of calls: “barks” and “hiccups”. This large range of calls is highlighted through cadencing, intonation, and frequency modulations that allow more detailed information to be conveyed.
+
+
+== Distribution and habitat ==
+The laughing kookaburra is native to eastern Australia and has a range that extends from the Cape York Peninsula in the north to Cape Otway in the south. It is present on both the eastern and the western sides of the Great Dividing Range. In the south the range extends westwards from Victoria to the Yorke Peninsula and the Flinders Ranges in South Australia.It has been introduced into many other areas probably because of its reputation for killing snakes. In December 1891, the Western Australian parliament included 'Laughing Jackass' in the schedule of strictly preserved Australian native birds in the Game Bill, moved by Horace Sholl, member for North District. He described it as native of the North West.  His nomination is, therefore, certainly a reference to the blue-winged kookaburra (Dacelo leachii), not the laughing kookaburra (Dacelo novaeguineae). The Game Act, 1892 (Western Australia), "An Act to provide for the preservation of imported birds and animals, and of native game," provided that proclaimed Australian native birds and animals listed in the First Schedule of the Act could be declared protected from taking. Laughing Jackass was one of 23 Australian native bird species named in the schedule. Laughing kookaburras from Eastern States were released near Mullewa in around 1896 and over the following decade hundreds of birds were imported from Victoria and released around Perth. By 1912 breeding populations had been established in a number of areas. The present range in Western Australia is southwest of a line joining Geraldton on the west coast and Hopetoun on the south coast. In Tasmania the laughing kookaburra was introduced at several locations beginning in 1906. It now mainly occurs northeast of a line joining Huonville, Lake Rowallan, Waratah and Marrawah. It was introduced on Flinders Island in around 1940, where it is now widespread, and on Kangaroo Island in 1926.In the 1860s, during his second term as governor of New Zealand, George Grey arranged for the release of laughing kookaburras on Kawau Island. The island lies in the Hauraki Gulf, about 40 km (25 mi) north of Auckland on the North Island of New Zealand. It was thought that the introduction had been unsuccessful but in 1916 some birds were discovered on the adjacent mainland. It now breeds in a small region on the western side of the Hauraki Gulf between Leigh and Kumeu.The usual habitat is open sclerophyll forest and woodland. It is more common where the understory is open and sparse or where the ground is covered with grass. Tree-holes are needed for nesting. It also occurs near wetlands and in partly cleared areas or farmland with trees along roads and fences. In urban areas it is found in parks and gardens. The range of the laughing kookaburra overlaps with that of the blue-winged kookaburra in an area of eastern Queensland that extends from the Cape York Peninsula south to near Brisbane. Around Cooktown the laughing kookaburra tends to favour areas near water while the blue-winged kookaburra keeps to drier habitats.
+
+
+== Behaviour ==
+
+Kookaburras occupy woodland territories (including forests) in loose family groups, and their laughter serves the same purpose as a great many other bird calls—to mark territorial borders. Most species of kookaburras tend to live in family units, with offspring helping the parents hunt and care for the next generation of offspring.
+
+
+=== Breeding ===
+
+During mating season, the laughing kookaburra reputedly indulges in behaviour similar to that of a wattlebird. The female adopts a begging posture and vocalises like a young bird. The male then offers her his current catch accompanied with an "oo oo oo" sound. However, some observers maintain that the opposite happens – the female approaches the male with her current catch and offers it to him. Nest-building may start in August with a peak of egg-laying from September to November. If the first clutch fails, they will continue breeding into the summer months.The female generally lays a clutch of three semi-glossy, white, rounded eggs, measuring 36 mm × 45 mm (1.4 in × 1.8 in), at about two-day intervals. Both parents and auxiliaries incubate the eggs for 24–26 days. Hatchlings are altricial and nidicolous, fledging by day 32–40.  If the food supply is not adequate, the third egg will be smaller and the third chick will also be smaller and at a disadvantage relative to its larger siblings. Chicks have a hook on the upper mandible, which disappears by the time of fledging. If the food supply to the chicks is not adequate, the chicks will quarrel, with the hook being used as a weapon. The smallest chick may even be killed by its larger siblings. If food is plentiful, the parent birds spend more time brooding the chicks, so the chicks are not able to fight.
+
+
+=== Feeding ===
+
+Kookaburras hunt much as other kingfishers (or indeed Australasian robins) do, by perching on a convenient branch or wire and waiting patiently for prey to pass by. Common prey include mice and similar-sized small mammals, a large variety of invertebrates (such as insects, earthworms and snails), yabbies, small fish, lizards, frogs, small birds and nestlings, and most famously, snakes.  Small prey are preferred, but kookaburras sometimes take large creatures, including venomous snakes, much longer than their bodies. When feeding their young, adult laughing kookaburras will make “Chuck calls”, which are deep, guttural calls that differ significantly from their daily chorus songs.
+
+
+=== Visual Displays ===
+To further enhance territorial behavior, kookaburras will partake in two types of aerial displays: trapeze and circular flights. Trapeze flights are aptly named after the swooping motion that neighboring kookaburras will make towards one another in midair when defending territory. During trapeze flights, an individual from each riot will perch on branches bordering the others’ territory and fly back and forth between trees within their established home range and trees bordering neighboring kookaburras territory. These displays have been observed to last up to a half an hour and are usually accompanied by calls from the sender and members of that individual's riot. Circle flights are initiated when an individual circumnavigates a neighboring territory by flying over the area and then quickly invading neighboring territory. Once inside the neighboring territory, the individual will fly in circles around the other kookaburras inhabiting the area, which results in a typical laughing call or squawking depending on whether the neighbors’ dominance status. Flight displays are useful for communicating over long distances, but other forms of visual signals can be effective for short-range communication.
+Close range visual signals can be used to convey aggression or indicate incoming threats to the flock. Aggressive posturing is used as a warning before attacking, a signal that is commonly received by foreign kookaburras encroaching on another groups’ territory. Laughing kookaburras will splay out their wings and propel their head forward while shaking their tail feathers to exhibit dominance and ward off intruders. The aggressive posturing is followed up by chasing off the unwanted individual before attacking. Visual displays are also used to communicate vigilance and the presence of threats via alert postures. D. novaeguineae will open its beak, ruffle up the feathers surrounding its cap, and angle their heads towards the direction of the threat. Depending on the urgency of the threat, alarm postures may be followed by loud laugh-like calls to warn other members of the flock.
+
+
+== Relationship with humans ==
+Laughing kookaburras are a common sight in suburban gardens and urban settings, even in built-up areas, and are so tame that they will often eat out of a person's hands, and allow them to rub their bellies. It is not uncommon for kookaburras to snatch food out of people's hands without warning, by swooping in from a distance. People often feed them pieces of raw meat. Laughing kookaburras are often kept in zoos.
+The kookaburra is also the subject of a popular Australian children's song, the "Kookaburra" which was written by Marion Sinclair in 1934.Recordings of this bird have been edited into Hollywood movies for decades, usually in jungle settings, beginning with the Tarzan series in the 1930s, and more recently in the film The Lost World: Jurassic Park (1997).
+
+
+== Conservation status ==
+
+The population density of the laughing kookaburra in Australia varies between 0.04 and 0.8 birds/ha depending on the habitat. Assuming an average of 0.3 birds/ha the total population may be as large as 65 million individuals. However, this may represent a severe over-estimate since the population of the laughing kookaburra seems to be undergoing a marked decline with Birdata showing a 50% drop in sightings from 2000 to 2019, and a drop in the reporting rate from 25% to 15% over the same period. The population in New Zealand is relatively small and is probably less than 500 individuals. Given the extended range and the large stable population, the species is evaluated as of "least concern" by the International Union for Conservation of Nature.

+The fulvous whistling duck or fulvous tree duck (Dendrocygna bicolor) is a species of whistling duck that breeds across the world's tropical regions in much of Mexico and South America, the West Indies, the southern United States, sub-Saharan Africa and the Indian subcontinent. It has plumage that is mainly reddish brown, long legs and a long grey bill, and shows a distinctive white band across its black tail in flight. Like other members of its ancient lineage, it has a whistling call which is given in flight or on the ground. Its preferred habitat consists of wetlands with plentiful vegetation, including shallow lakes and paddy fields.
+The nest, built from plant material and unlined, is placed among dense vegetation or in a tree hole. The typical clutch is around ten whitish eggs. The breeding adults, which pair for life, take turns to incubate, and the eggs hatch in 24–29 days. The downy grey ducklings leave the nest within a day or so of hatching, but the parents continue to protect them until they fledge around nine weeks later.
+The fulvous whistling duck feeds in wetlands by day or night on seeds and other parts of plants. It is sometimes regarded as a pest of rice cultivation, and is also shot for food in parts of its range. Despite hunting, poisoning by pesticides and natural predation by mammals, birds, and reptiles, the large numbers and huge range of this duck mean that it is classified as least concern by the International Union for Conservation of Nature.
+
+
+== Taxonomy ==
+The whistling ducks, Dendrocygna, are a distinctive group of eight bird species within the duck, goose and swan family, Anatidae, which are characterised by a hump-backed, long-necked appearance and the whistled flight calls that give them their English name. They were an early split from the main duck lineage, and were predominant in the Late Miocene before the subsequent extensive radiation of more modern forms in the Pliocene and later. The fulvous whistling duck forms a superspecies with the wandering whistling duck. It has no recognised subspecies, although the birds in northern Mexico and the southern US have in the past been assigned to D. b. helva, described as having paler and brighter underparts and a lighter crown than D. b. bicolor.The duck was first described by Johann Friedrich Gmelin in 1789 and given the name Anas fulva but the name was "preoccupied", or already used, by Friedrich Christian Meuschen in 1787 for another species. This led to the next available name proposed by French ornithologist Louis Jean Pierre Vieillot in 1816 from a Paraguayan specimen as Anas bicolor. The whistling ducks were moved to their current genus, Dendrocygna, by British ornithologist William John Swainson in recognition of their differences from other ducks. The genus name is derived from the Ancient Greek dendron, "tree", and Latin cygnus, "swan", and  bicolor is Latin for "two-coloured". "Fulvous" means reddish-yellow, and is derived from the Latin equivalent fulvus. Old and regional names include large whistling teal, brown tree duck, Mexican duck, pichiguila, squealer and Spanish cavalier.
+
+
+== Description ==
+The fulvous whistling duck is 45–53 cm (18–21 in) long; the male weighs 748–1,050 g (26.4–37.0 oz), and the female averages marginally lighter at 712–1,000 g (25.1–35.3 oz). The wingspan ranges from 85 to 93 cm.It is a long-legged duck, mainly different shades of brown; head, neck and breast are particularly rich buff (fulvous) with a darker back. The mantle is more darker shade of brown with buff-tipped feathers, the flight feathers and tail are dark brown, and a dark brown to black stripe runs through the center of the crown down the back of the neck to the base of the mantle. It has whitish stripes on its flanks, a long grey bill and grey legs. In flight, the wings are brown above and black below, with no white markings, and a white crescent on the rump contrasts with the black tail. All plumages are fairly similar, but the female is slightly smaller and duller-plumaged than the male. The juvenile has paler underparts, and appears generally duller, especially on the flanks. There is a complete wing moult after breeding, and birds then seek the cover of dense wetland vegetation while they are flightless. Body feathers may be moulted throughout the year; each feather is replaced only once annually.These are noisy birds with a clear whistling kee-wee-ooo call given on the ground or in flight, frequently heard at night. Quarrelling birds also have a harsh repeated kee. In flight, the beating wings produce a dull sound. The calls of males and females show differences in structure and an acoustic analysis on 59 captive birds demonstrated 100% accuracy in sexing when compared with molecular methods.Adult birds in Asia can be confused with the similar lesser whistling duck, which is smaller, has a blackish crown and lacks an obvious dark stripe down the back of the neck. Juvenile fulvous whistling ducks are very like young lesser whistling ducks, but the crown colour is still a distinction. Juvenile comb ducks are bulkier than whistling ducks and have a dark cap to the head. In South America and Africa, juvenile white-faced whistling ducks are separable from fulvous by their dark crowns, barred flanks and chestnut breasts.
+
+
+== Distribution and habitat ==
+
+The fulvous whistling duck has a very large range extending across four continents. It breeds in lowland South America from northern Argentina to Colombia and then up to the southern US and the West Indies. It is found in a broad belt across sub-Saharan Africa and down the east of the continent to South Africa and Madagascar. The Indian subcontinent is the Asian stronghold. It undertakes seasonal movements in response to the availability of water and food. African birds move southwards in the southern summer to breed and return north in the winter, and Asian populations are highly nomadic due to the variability of rainfall. This species has strong colonising tendencies, having expanded its range in Mexico, the US and the West Indies in recent decades with northerly range expansions into California in late 19th century and rice-growing regions of the U.S. Gulf Coastal Plain in the early to mid-20th century, given its affinity for rice-growing areas. Breeding in the northern American region is restricted to the Gulf Coastal Plain of Texas and Louisiana and localities in southern California and south- and east-central Florida. Observations of the bird outside the nesting season, especially since the 1950s have been recorded in temperate regions as far north as the Mississippi River Basin, eastern Great Lakes region, and along the Pacific and Atlantic Coasts right up to southern Canada. Wandering birds can turn up far beyond the normal range, sometimes staying to nest, as in Morocco, Peru and Hawaii.The fulvous whistling duck is found in lowland marshes and swamps in open, rice fields, flat country, and it avoids wooded areas. It is not normally a mountain species, breeding in Venezuela, for example, only up 300 m (980 ft), but the single Peruvian breeding record was at 4,080 m (13,390 ft).
+
+
+== Behaviour ==
+
+This species is usually found in small groups, but substantial flocks can form at favoured sites. It walks well, without waddling, and normally feeds by upending, though it can dive if necessary. It does not often perch in trees, unlike other whistling ducks. It flies at low altitude with slow wingbeats and trailing feet, in loose flocks rather than tight formation. It feeds during the day and at night in fairly large flocks, often with other whistling duck species, but rests or sleeps in smaller groups in the middle of the day. They are noisy and display their aggression towards other individuals by throwing back their heads. Before taking off in alarm, they often shake their head sideways.Several arthropod parasites have been recorded on this duck, including chewing mites of the families Philopteridae and Menoponidae, feather mites and skin mites. Internal helminth parasites include roundworms, tapeworms and flukes. In a survey in Florida, all 30 ducks tested carried at least two helminth species; none had blood parasites. Only one duck had no mites or lice.
+
+
+=== Breeding ===
+
+Breeding coincides with the availability of water. In South America and South Africa, the main nesting period is December–February, in Nigeria it is July–December, and in North America mid-May–August. In India, the breeding season is from June to October but peaking in July and August. Fulvous whistling ducks show lifelong monogamy; the courtship display is limited to some mutual head-dipping before mating and a short dance after copulation in which the birds raise their bodies side by side while treading water.Pairs may breed alone or in loose groups. In South Africa, nests may be within 50 m (160 ft) of each other, and breeding densities of up to 13.7 nests per square kilometre (35.5 per square mile) have been found in Louisiana. The nest, 19–26 cm (7.5–10.2 in) across, is made from plant leaves and stems and has little or no soft lining. It is usually built on the ground (unlike the Black-bellied whistling duck), in marsh vegetation, and in artificial habitats such as shallowly-flooded rice fields, in dense vegetation and close to water, but sometimes in tree holes. In India, the use of tree holes, and even the old nests of raptors or crows, is much more common than elsewhere. Eggs are laid at roughly 24- to 36-hour intervals, starting before the nest is complete, resulting in some losses from the clutch. They are whitish and on average measure 53.4 mm × 40.7 mm (2.10 in × 1.60 in) and weigh 50.4 g (1.78 oz). The clutch is usually around ten eggs, but other females sometimes lay into the nest, so 20 or more may be found on occasion. Eggs may also be added to the nests of other species, like ruddy duck.Both sexes incubate, changing over once a day, with the male often taking the greater share of this duty. The eggs hatch in about 24–29 days, The downy ducklings are grey, with paler upperparts, and a white band on the neck, and weigh 22–38 g (0.78–1.34 oz) within a day of hatching. Like all ducklings, they are precocial and leave the nest after a day or so, but the parents protect them until they fledge around nine weeks later. Eggs and duckling may be preyed on by mammals, birds and reptiles; one parent may try to distract a potential predator with a broken-wing display while the other adult leads the ducklings away. Birds are sexually mature after one year, and the maximum known age is 6.5 years.In South Africa, a few records of hybridization with the white-faced whistling duck have been noted in the wild; in most parts of southern Africa, the two species breed at different times, bicolor during the dry season (April to September) and viduata during the rains (October to March). Hybridization in captivity is more frequent but limited to other species in the genus Dendrocygna.
+
+
+== Feeding ==
+
+The fulvous whistling duck feeds in wetlands by day or night, often in mixed flocks with relatives such as white-faced or black-bellied whistling ducks. Its food is generally plant material, including seeds, bulbs, grasses and stems, but females may include animal items such as aquatic worms, molluscs and insects as they prepare for egg-laying, which may then comprise up to 4% of their diet. Ducklings may also eat a few insects. Foraging is by picking plant items while walking or swimming, by upending, or occasionally by diving to a depth of up to 1 m (3.3 ft). Favoured plants include water snowflake, aquatic ragweeds, bourgou millet, shama grass, Cape blue water lily, waxy-leaf nightshade, beakrush, flatsedge and polygonums. Rice is normally a small part of the diet, and a survey in Cuban rice fields found that the plants taken were mainly weeds growing with the crop. However, in a study in Louisiana, 25% of the diet of incubating females consisted of cereal.
+
+
+== Status ==
+The International Union for Conservation of Nature (IUCN) estimates the population of the fulvous whistling duck to be from 1.3 to 1.5 million individuals around the world. This may be an underestimate since regional assessments suggest 1 million birds in the Americas, 1.1 million in Africa and at least 20,000 in South Asia for a grand total of 2.12 million ducks around the world. The population appears to be declining, but the decrease is not rapid enough to trigger the vulnerability criteria for extinction. The large numbers and huge breeding range mean that this duck is classified by the IUCN as being of Least Concern. It is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.The fulvous whistling duck has expanded its range in the West Indies, and into the southern US. A series of invasions from South America and reaching the eastern US commenced around 1948, fueled by rice cultivation, and breeding was recorded in Cuba in 1964, and Florida in 1965. Some Florida birds still winter in Cuba. In Africa, it bred on the Cape Peninsula between 1940 and the 1960s. A survey of eighteen species which had colonised the area in recent decades found that most were wetland species that had used irrigated farmland as "stepping stones" across the arid country separating the peninsula from the breeding main range. However, the status of the two whistling duck species featured in the research is dubious since they are popular ornamental species, so their origin is unclear.Outside North America it is subject to hunting for food or because of its liking for rice, and persecution means that it is now rare in Madagascar. Pesticides used on rice fields may also have an adverse impact, causing liver and breast muscle damage even at sub-lethal levels.

+The red-shouldered macaw (Diopsittaca nobilis) is a small green South American parrot, a member of a large group of Neotropical parrots called macaws. The species is named for the red coverts on its wings. It is the smallest macaw, being 30–35 cm (12–14 in) in length - similar in size to the Aratinga parakeets. It is native to the tropical lowlands, savannah, and swamplands of Brazil, the Guianas, Bolivia, Venezuela, and far south-eastern Peru. It has two distinct subspecies, the noble macaw and the Hahn's macaw, and a possible poorly distinct third subspecies that has longer wings, but is otherwise similar to the noble macaw. The Hahn's subspecies is named for German zoologist Carl-Wilhelm Hahn, who in 1834 began compiling Ornithologischer Atlas oder naturgetreue Abbildung und Beschreibung der aussereuropäischen Vögel (Engl: Ornithological Atlas or natural depiction and description of birds from outside Europe).Red-shouldered macaws are frequently bred in captivity for the pet trade, where they are sometimes described as mini-macaws.
+Though wild populations of red-shouldered macaws have declined locally due to habitat loss, they are listed as Least Concern by IUCN. They are listed on Appendix II of CITES, trade restricted.
+
+
+== Taxonomy ==
+The red-shouldered macaw was formally described in 1758 by the Swedish naturalist Carl Linnaeusin the tenth edition of his Systema Naturae. He placed it with all the other parrots in the genus Psittacus and coined the binomial name Psittacus nobilis. The red-shouldered macaw is now the only species placed in the genus Diopsittaca that was introduced in 1912 by the American ornithologist Robert Ridgway. The genus name combines the Ancient Greek dios meaning "noble" with psittakē meaning "parrot". The specific epithet noblilis is Latin meaning "noble". There are two distinct subspecies, D. n. nobilis (Hahn's macaw) and D. n. cumanensis (noble macaw), and some with longer wings might represent a poorly differentiated subspecies, D. n. longipennis, which intergrades with D. n. cumanensis in central Goiás, Brazil. The species is sometimes subsumed into the genus Ara.Taxonomy proposed by BirdLife International splits the red-shouldered macaw into two species.
+
+Northern red-shouldered macaw (Diopsittaca nobilis)
+Southern red-shouldered macaw (Diopsittaca cumanensis)
+
+
+== Description ==
+The red-shouldered macaw, at 30 cm (12 in) long and 165 g (5.8 oz) weight, is the smallest of all the macaws. Like all macaws, it has a long narrow tail and a large head. It has bright green feathers on the body, with dark or slate blue feathers on the head just above the beak. The wings and tail have feathers that are bright green above and olive-green below. The leading edges of the wings, especially on the underside, are red.  (These red feathers appear at puberty.) Their eyes are orange, and the skin around the eyes is white without feathers, just as in the larger macaws. This bare patch of facial skin is smaller in proportion to the head than the one seen in most larger macaws. The Hahn's macaw and noble macaw can be distinguished by the Hahn's having a black upper mandible and the Noble's having a lighter, horn-colored upper mandible.
+Their natural vocalizations are more akin to screeches than they are to whistles.
+
+
+== Behavior ==
+Red-shouldered macaws are very kind natured. Their personality is similar to the large macaws.
+
+
+=== Breeding ===
+
+The red-shouldered macaw nests in a hole in a tree. There are usually three or four white eggs in a clutch. The female incubates the eggs for about 24 to 26 days, and the chicks fledge from the nest about 54 days after hatching.
+
+
+== Aviculture ==
+Although a noisy bird that is not suitable for apartment living, the red-shouldered macaw can be an excellent pet. If properly socialized, it is typically a gentle, intelligent bird that bonds well with humans and gets on well with well-behaved children. In addition, it is an excellent talker that can be taught many tricks. It may be a more suitable pet parrot for those who lack the space in their homes for a larger macaw, although it requires daily exercise outside of its cage. It is also recommended by the World Parrot Trust that this parrot should have access to an outside enclosure for at least part of the year. The red-shouldered macaw can live for 25-40 years in captivity.

+The emu () (Dromaius novaehollandiae) is the second-tallest living bird after its ratite relative the ostrich. It is endemic to Australia where it is the largest native bird and the only extant member of the genus Dromaius. The emu's range covers most of mainland Australia, but the Tasmanian, Kangaroo Island and King Island subspecies became extinct after the European settlement of Australia in 1788.
+Emus are soft-feathered, brown, flightless birds with long necks and legs, and can reach up to 1.9 metres (6.2 ft) in height. Emus can travel great distances, and when necessary can sprint at 48 km/h (30 mph); they forage for a variety of plants and insects, but have been known to go for weeks without eating. They drink infrequently, but take in copious amounts of water when the opportunity arises.
+Breeding takes place in May and June, and fighting among females for a mate is common. Females can mate several times and lay several clutches of eggs in one season. The male does the incubation; during this process he hardly eats or drinks and loses a significant amount of weight. The eggs hatch after around eight weeks, and the young are nurtured by their fathers. They reach full size after around six months, but can remain as a family unit until the next breeding season. The emu is an important cultural icon of Australia, appearing on the coat of arms and various coins. The bird features prominently in Indigenous Australian mythology.
+The bird is sufficiently common for it to be rated as a least-concern species by the International Union for Conservation of Nature. Despite this, some local populations are listed as endangered, with subspecies such as the Tasmanian emu going extinct by the 1800s. Threats to their survival include predation of their eggs, roadkills, and fragmentation of their habitats.
+
+
+== Etymology ==
+The etymology of the common name "emu" is uncertain, but is thought to have come from an Arabic word for large bird that was later used by Portuguese explorers to describe the related cassowary in Australia and New Guinea. Another theory is that it comes from the word "ema", which is used in Portuguese to denote a large bird akin to an ostrich or crane. In Victoria, some terms for the emu were Barrimal in the Dja Dja Wurrung language, myoure in Gunai, and courn in Jardwadjali. The birds were known as murawung or birabayin to the local Eora and Darug inhabitants of the Sydney basin.
+
+
+== Taxonomy ==
+
+
+=== History ===
+Emus were first reported as having been seen by Europeans when explorers visited the western coast of Australia in 1696. This was during an expedition led by Dutch captain Willem de Vlamingh who was searching for survivors of a ship that had gone missing two years earlier. The birds were known on the eastern coast before 1788, when the first Europeans settled there. The birds were first mentioned under the name of the "New Holland cassowary" in Arthur Phillip's Voyage to Botany Bay, published in 1789 with the following description:
+This is a species differing in many particulars from that generally known, and is a much larger bird, standing higher on its legs and having the neck longer than in the common one. Total length seven feet two inches. The bill is not greatly different from that of the common Cassowary; but the horny appendage, or helmet on top of the head, in this species is totally wanting: the whole of the head and neck is also covered with feathers, except the throat and fore part of the neck about half way, which are not so well feathered as the rest; whereas in the common Cassowary the head and neck are bare and carunculated as in the turkey.
+The plumage in general consists of a mixture of brown and grey, and the feathers are somewhat curled or bent at the ends in the natural state: the wings are so very short as to be totally useless for flight, and indeed, are scarcely to be distinguished from the rest of the plumage, were it not for their standing out a little. The long spines which are seen in the wings of the common sort, are in this not observable,—nor is there any appearance of a tail. The legs are stout, formed much as in the Galeated Cassowary, with the addition of their being jagged or sawed the whole of their length at the back part.

+The species was named by ornithologist John Latham in 1790 based on a specimen from the Sydney area of Australia, a country which was known as New Holland at the time. He collaborated on Phillip's book and provided the first descriptions of, and names for, many Australian bird species; Dromaius comes from a Greek word meaning "racer" and novaehollandiae is the Latin term for New Holland, so the name can be rendered as "fast-footed New Hollander". In his original 1816 description of the emu, the French ornithologist Louis Jean Pierre Vieillot used two generic names, first Dromiceius and later Dromaius. It has been a point of contention ever since as to which name should be used; the latter is more correctly formed, but the convention in taxonomy is that the first name given to an organism stands, unless it is clearly a typographical error. Most modern publications, including those of the Australian government, use Dromaius, with Dromiceius mentioned as an alternative spelling.

+
+=== Systematics ===
+The emu was long classified, with its closest relatives the cassowaries, in the family Casuariidae, part of the ratite order Struthioniformes. An alternate classification was proposed in 2014 by Mitchell et al., based on analysis of mitochondrial DNA. This splits off the Casuariidae into their own order, the Casuariformes, and includes only the cassowaries in the family Casuariidae, placing the emus in their own family, Dromaiidae. The cladogram shown below is from their study.
+Two different Dromaius species were present in Australia at the time of European settlement, and one additional species is known from fossil remains. The insular dwarf emus, D. n. baudinianus and D. n. minor, originally present on Kangaroo Island and King Island respectively, both became extinct shortly after the arrival of Europeans. D. n. diemenensis, another insular dwarf emu from Tasmania, became extinct around 1865. The mainland subspecies, D. n. novaehollandiae, remains common. The population of these birds varies from decade to decade, largely being dependent on rainfall; in 2009, it was estimated that there were between 630,000 and 725,000 birds. Emus were introduced to Maria Island off Tasmania, and Kangaroo Island off the coast of South Australia, during the 20th century. The Maria Island population died out in the mid-1990s. The Kangaroo Island birds have successfully established a breeding population.In 1912, the Australian ornithologist Gregory M. Mathews recognised three living subspecies of emu, D. n. novaehollandiae (Latham, 1790), D. n. woodwardi Mathews, 1912 and D. n. rothschildi Mathews, 1912. The Handbook of the Birds of the World, however, argues that the last two of these subspecies are invalid; natural variations in plumage colour and the nomadic nature of the species make it likely that there is a single race in mainland Australia. Examination of the DNA of the King Island emu shows this bird to be closely related to the mainland emu and hence best treated as a subspecies.

+
+== Description ==
+The emu is the second tallest bird in the world, only being exceeded in height by the ostrich; the largest individuals can reach up to 150 to 190 cm (59 to 75 in) in height. Measured from the bill to the tail, emus range in length from 139 to 164 cm (55 to 65 in), with males averaging 148.5 cm (58.5 in) and females averaging 156.8 cm (61.7 in). Emus are the fourth or fifth heaviest living bird after the two species of ostrich and two larger species of cassowary, weighing slightly more on average than an emperor penguin. Adult emus weigh between 18 and 60 kg (40 and 132 lb), with an average of 31.5 and 37 kg (69 and 82 lb) in males and females, respectively. Females are usually slightly larger than males and are substantially wider across the rump.
+
+Although flightless, emus have vestigial wings, the wing chord measuring around 20 cm (8 in), and each wing having a small claw at the tip. Emus flap their wings when running, perhaps as a means of stabilising themselves when moving fast. They have long necks and legs, and can run at speeds of 48 km/h (30 mph) due to their highly specialised pelvic limb musculature. Their feet have only three toes and a similarly reduced number of bones and associated foot muscles; emus are unique among birds in that their gastrocnemius muscles in the back of the lower legs have four bellies instead of the usual three. The pelvic limb muscles of emus contribute a similar proportion of the total body mass as do the flight muscles of flying birds. When walking, the emu takes strides of about 100 cm (3.3 ft), but at full gallop, a stride can be as long as 275 cm (9 ft). Its legs are devoid of feathers and underneath its feet are thick, cushioned pads. Like the cassowary, the emu has sharp claws on its toes which are its major defensive attribute, and are used in combat to inflict wounds on opponents by kicking. The toe and claw total 15 cm (6 in) in length. The bill is quite small, measuring 5.6 to 6.7 cm (2.2 to 2.6 in), and is soft, being adapted for grazing. Emus have good eyesight and hearing, which allows them to detect threats at some distance.The neck of the emu is pale blue and shows through its sparse feathers. They have grey-brown plumage of shaggy appearance; the shafts and the tips of the feathers are black. Solar radiation is absorbed by the tips, and the inner plumage insulates the skin. This prevents the birds from overheating, allowing them to be active during the heat of the day. A unique feature of the emu feather is the double rachis emerging from a single shaft. Both of the rachis have the same length, and the texture is variable; the area near the skin is rather furry, but the more distant ends resemble grass. The sexes are similar in appearance, although the male's penis can become visible when he urinates and defecates. The plumage varies in colour due to environmental factors, giving the bird a natural camouflage. Feathers of emus in more arid areas with red soils have a rufous tint while birds residing in damp conditions are generally darker in hue. The juvenile plumage develops at about three months and is blackish finely barred with brown, with the head and neck being especially dark. The facial feathers gradually thin to expose the bluish skin. The adult plumage has developed by about fifteen months.The eyes of an emu are protected by nictitating membranes. These are translucent, secondary eyelids that move horizontally from the inside edge of the eye to the outside edge. They function as visors to protect the eyes from the dust that is prevalent in windy arid regions. Emus have a tracheal pouch, which becomes more prominent during the mating season. At more than 30 cm (12 in) in length, it is quite spacious; it has a thin wall, and an opening 8 centimetres (3 in) long.
+
+
+== Distribution and habitat ==
+
+Once common on the east coast of Australia, emus are now uncommon there; by contrast, the development of agriculture and the provision of water for stock in the interior of the continent have increased the range of the emu in arid regions. Emus live in various habitats across Australia both inland and near the coast. They are most common in areas of savannah woodland and sclerophyll forest, and least common in heavily populated districts and arid areas with annual precipitation of less than 600 millimetres (24 in). Emus predominantly travel in pairs, and while they can form large flocks, this is an atypical social behaviour that arises from the common need to move towards a new food source. Emus have been shown to travel long distances to reach abundant feeding areas. In Western Australia, emu movements follow a distinct seasonal pattern – north in summer and south in winter. On the east coast their wanderings seem to be more random and do not appear to follow a set pattern.
+
+
+== Behaviour and ecology ==
+Emus are diurnal birds and spend their day foraging, preening their plumage with their beak, dust bathing and resting. They are generally gregarious birds apart from the breeding season, and while some forage, others remain vigilant to their mutual benefit. They are able to swim when necessary, although they rarely do so unless the area is flooded or they need to cross a river.
+
+Emus begin to settle down at sunset and sleep during the night. They do not sleep continuously but rouse themselves several times during the night. When falling asleep, emus first squat on their tarsi and enter a drowsy state during which they are alert enough to react to stimuli and quickly return to a fully awakened state if disturbed. As they fall into deeper sleep, their neck droops closer to the body and the eyelids begin to close. If there are no disturbances, they fall into a deeper sleep after about twenty minutes. During this phase, the body is gradually lowered until it is touching the ground with the legs folded underneath. The beak is turned down so that the whole neck becomes S-shaped and folded onto itself. The feathers direct any rain downwards onto the ground. It has been suggested that the sleeping position is a type of camouflage, mimicking a small mound. Emus typically awake from deep sleep once every ninety minutes or so and stand upright to feed briefly or defecate. This period of wakefulness lasts for ten to twenty minutes, after which they return to slumber. Overall, an emu sleeps for around seven hours in each twenty-four-hour period. Young emus usually sleep with their neck flat and stretched forward along the ground surface.
+
+The vocalisations of emus mostly consist of various booming and grunting sounds. The booming is created by the inflatable throat pouch; the pitch can be regulated by the bird and depends on the size of the aperture. Most of the booming is done by females; it is part of the courtship ritual, is used to announce the holding of territory and is issued as a threat to rivals. A high-intensity boom is audible 2 kilometres (1.2 mi) away, while a low, more resonant call, produced during the breeding season, may at first attract mates and peaks while the male is incubating the eggs. Most of the grunting is done by males. It is used principally during the breeding season in territorial defence, as a threat to other males, during courtship and while the female is laying. Both sexes sometimes boom or grunt during threat displays or on encountering strange objects.On very hot days, emus pant to maintain their body temperature. Their lungs work as evaporative coolers and, unlike some other species, the resulting low levels of carbon dioxide in the blood do not appear to cause alkalosis. For normal breathing in cooler weather, they have large, multifolded nasal passages. Cool air warms as it passes through into the lungs, extracting heat from the nasal region. On exhalation, the emu's cold nasal turbinates condense moisture back out of the air and absorb it for reuse. As with other ratites, the emu has great homeothermic ability, and can maintain this status from −5 to 45 °C (23 to 113 °F). The thermoneutral zone of emus lies between 10 and 30 °C (50 and 86 °F).
+
+As with other ratites, emus have a relatively low basal metabolic rate compared to other types of birds. At −5 °C (23 °F), the metabolic rate of an emu sitting down is about 60% of that when standing, partly because the lack of feathers under the stomach leads to a higher rate of heat loss when standing from the exposed underbelly.
+
+
+=== Diet ===
+
+Emus forage in a diurnal pattern and eat a variety of native and introduced plant species. The diet depends on seasonal availability with such plants as Acacia, Casuarina and grasses being favoured. They also eat insects and other arthropods, including grasshoppers and crickets, beetles, cockroaches, ladybirds, bogong and cotton-boll moth larvae, ants, spiders and millipedes. This provides a large part of their protein requirements. In Western Australia, food preferences have been observed in travelling emus; they eat seeds from Acacia aneura until the rains arrive, after which they move on to fresh grass shoots and caterpillars; in winter they feed on the leaves and pods of Cassia and in spring, they consume grasshoppers and the fruit of Santalum acuminatum, a sort of quandong. They are also known to feed on wheat, and any fruit or other crops that they can access, easily climbing over high fences if necessary. Emus serve as an important agent for the dispersal of large viable seeds, which contributes to floral biodiversity. One undesirable effect of this occurred in Queensland in the early twentieth century when emus fed on the fruit of prickly pears in the outback. They defecated the seeds in various places as they moved around, and this led to a series of campaigns to hunt emus and prevent the seeds of the invasive cactus being spread. The cacti were eventually controlled by an introduced moth (Cactoblastis cactorum) whose larvae fed on the plant, one of the earliest examples of biological control. The δ13C of the emu's diet is reflected in the δ13C of the calcite of its egg shell.Small stones are swallowed to assist in the grinding up and digestion of the plant material. Individual stones may weigh 45 g (1.6 oz) and the birds may have as much as 745 g (1.642 lb) in their gizzards at one time. They also eat charcoal, although the reason for this is unclear. Captive emus have been known to eat shards of glass, marbles, car keys, jewellery and nuts and bolts.Emus drink infrequently but ingest large amounts when the opportunity arises. They typically drink once a day, first inspecting the water body and surrounding area in groups before kneeling down at the edge to drink. They prefer being on firm ground while drinking, rather than on rocks or mud, but if they sense danger, they often stand rather than kneel. If not disturbed, they may drink continuously for ten minutes. Due to the scarcity of water sources, emus are sometimes forced to go without water for several days. In the wild, they often share water holes with kangaroos, other birds and animals; they are wary and tend to wait for the other animals to leave before drinking.
+
+
+=== Breeding ===
+
+Emus form breeding pairs during the summer months of December and January and may remain together for about five months. During this time, they stay in an area a few kilometres in diameter and it is believed they find and defend territory within this area. Both males and females put on weight during the breeding season, with the female becoming slightly heavier at between 45 and 58 kg (99 and 128 lb). Mating usually takes place between April and June; the exact timing is determined by the climate as the birds nest during the coolest part of the year. During the breeding season, males experience hormonal changes, including an increase in luteinising hormone and testosterone levels, and their testicles double in size.Males construct a rough nest in a semi-sheltered hollow on the ground, using bark, grass, sticks and leaves to line it. The nest is almost always a flat surface rather than a segment of a sphere, although in cold conditions the nest is taller, up to 7 cm (2.8 in) tall, and more spherical to provide some extra heat retention. When other material is lacking, the bird sometimes uses a spinifex tussock a metre or so across, despite the prickly nature of the foliage. The nest can be placed on open ground or near a shrub or rock. The nest is usually placed in an area where the emu has a clear view of its surroundings and can detect approaching predators.Female emus court the males; the female's plumage darkens slightly and the small patches of bare, featherless skin just below the eyes and near the beak turn turquoise-blue. The colour of the male's plumage remains unchanged, although the bare patches of skin also turn light blue.  When courting, females stride around, pulling their neck back while puffing out their feathers and emitting low, monosyllabic calls that have been compared to drum beats. This calling can occur when males are out of sight or more than 50 metres (160 ft) away.  Once the male's attention has been gained, the female circles her prospective mate at a distance of 10 to 40 metres (30 to 130 ft). As she does this, she looks at him by turning her neck, while at the same time keeping her rump facing towards him. If the male shows interest in the parading female, he will move closer; the female continues the courtship by shuffling further away but continuing to circle him.If a male is interested, he will stretch his neck and erect his feathers, then bend over and peck at the ground. He will circle around and sidle up to the female, swaying his body and neck from side to side, and rubbing his breast against his partner's rump. Often the female will reject his advances with aggression, but if amenable, she signals acceptance by squatting down and raising her rump.
+
+Females are more aggressive than males during the courtship period, often fighting for access to mates, with fights among females accounting for more than half the aggressive interactions during this period.  If females court a male that already has a partner, the incumbent female will try to repel the competitor, usually by chasing and kicking.  These interactions can be prolonged, lasting up to five hours, especially when the male being fought over is single and neither female has the advantage of incumbency. In these cases, the females typically intensify their calls and displays.The sperm from a mating is stored by the female and can suffice to fertilise about six eggs. The pair mate every day or two, and every second or third day the female lays one of a clutch of five to fifteen very large, thick-shelled, green eggs. The shell is around 1 mm (0.04 in) thick, but rather thinner in northern regions according to indigenous Australians. The shell is substantially composed of calcite, and its δ13C is a function of the emu's diet. The eggs are on average 13 cm × 9 cm (5.1 in × 3.5 in) and weigh between 450 and 650 g (1.0 and 1.4 lb). The maternal investment in the egg is considerable, and the proportion of yolk to albumen, at about 50%, is greater than would be predicted for a precocial egg of this size. This probably relates to the long incubation period which means the developing chick must consume greater resources before hatching. The first verified occurrence of genetically identical avian twins was demonstrated in the emu. The egg surface is granulated and pale green. During the incubation period, the egg turns dark green, although if the egg never hatches, it will turn white from the bleaching effect of the sun.The male becomes broody after his mate starts laying, and may begin to incubate the eggs before the clutch is complete. From this time on, he does not eat, drink, or defecate, and stands only to turn the eggs, which he does about ten times a day. He develops a brood patch, a bare area of wrinkled skin which is in intimate contact with the eggs. Over the course of the eight-week incubation period, he will lose a third of his weight and will survive on stored body fat and on any morning dew that he can reach from the nest. As with many other Australian birds, such as the superb fairywren, infidelity is the norm for emus, despite the initial pair bond: once the male starts brooding, the female usually wanders off, and may mate with other males and lay in multiple nests; thus, as many as half the chicks in a brood may not be fathered by the incubating male, or even by either parent, as emus also exhibit brood parasitism.
+
+Some females stay and defend the nest until the chicks start hatching, but most leave the nesting area completely to nest again; in a good season, a female emu may nest three times. If the parents stay together during the incubation period, they will take turns standing guard over the eggs while the other drinks and feeds within earshot. If it perceives a threat during this period, it will lie down on top of the nest and try to blend in with the similar-looking surrounds, and suddenly stand up to confront and scare the other party if it comes close.Incubation takes 56 days, and the male stops incubating the eggs shortly before they hatch. The temperature of the nest rises slightly during the eight-week period. Although the eggs are laid sequentially, they tend to hatch within two days of one another, as the eggs that were laid later experienced higher temperatures and developed more rapidly. During the process, the precocial emu chicks need to develop a capacity for thermoregulation. During incubation, the embryos are kept at a constant temperature but the chicks will need to be able to cope with varying external temperatures by the time they hatch.Newly hatched chicks are active and can leave the nest within a few days of hatching. They stand about 12 cm (5 in) tall at first, weigh 0.5 kg (17.6 oz), and have distinctive brown and cream stripes for camouflage, which fade after three months or so. The male guards the growing chicks for up to seven months, teaching them how to find food. Chicks grow very quickly and are fully grown in five to six months; they may remain with their family group for another six months or so before they split up to breed in their second season. During their early life, the young emus are defended by their father, who adopts a belligerent stance towards other emus, including the mother. He does this by ruffling his feathers, emitting sharp grunts, and kicking his legs to drive off other animals. He can also bend his knees to crouch over smaller chicks to protect them. At night, he envelops his young with his feathers. As the young emus cannot travel far, the parents must choose an area with plentiful food in which to breed. In captivity, emus can live for upwards of ten years.
+
+
+=== Predation ===
+
+There are few native natural predators of emus still extant. Early in its species history it may have faced numerous terrestrial predators now extinct, including the giant lizard Megalania, the thylacine, and possibly other carnivorous marsupials, which may explain their seemingly well-developed ability to defend themselves from terrestrial predators. The main predator of emus today is the dingo, which was originally introduced by Aboriginals thousands of years ago from a stock of semi-domesticated wolves. Dingoes try to kill the emu by attacking the head. The emu typically tries to repel the dingo by jumping into the air and kicking or stamping the dingo on its way down. The emu jumps as the dingo barely has the capacity to jump high enough to threaten its neck, so a correctly timed leap to coincide with the dingo's lunge can keep its head and neck out of danger.Despite the potential prey-predator relationship, the presence of predaceous dingoes does not appear to heavily influence emu numbers, with other natural conditions just as likely to cause mortality. Wedge-tailed eagles are the only avian predator capable of attacking fully-grown emus, though are perhaps most likely to take small or young specimens. The eagles attack emus by swooping downwards rapidly and at high speed and aiming for the head and neck. In this case, the emu's jumping technique as employed against the dingo is not useful. The birds try to target the emu in open ground so that it cannot hide behind obstacles. Under such circumstances, the emu can only run in a chaotic manner and change directions frequently to try to evade its attacker. Other raptors, monitor lizards, introduced red foxes, feral and domestic dogs, and feral pigs occasionally feed on emu eggs or kill small chicks.
+
+
+=== Parasites ===
+Emus can suffer from both external and internal parasites, but under farmed conditions are more parasite-free than ostriches or rheas. External parasites include the louse Dahlemhornia asymmetrica and various other lice, ticks, mites and flies. Chicks sometimes suffer from intestinal tract infections caused by coccidian protozoa, and the nematode Trichostrongylus tenuis infects the emu as well as a wide range of other birds, causing haemorrhagic diarrhoea. Other nematodes are found in the trachea and bronchi; Syngamus trachea causing haemorrhagic tracheitis and Cyathostoma variegatum causing serious respiratory problems in juveniles.
+
+
+== Relationship with humans ==
+
+Emus were used as a source of food by indigenous Australians and early European settlers. Emus are inquisitive birds and have been known to approach humans if they see unexpected movement of a limb or piece of clothing. In the wild, they may follow and observe people. Aboriginal Australians used a variety of techniques to catch the birds, including spearing them while they drank at waterholes, catching them in nets, and attracting them by imitating their calls or by arousing their curiosity with a ball of feathers and rags dangled from a tree. The pitchuri thornapple (Duboisia hopwoodii), or some similar poisonous plant, could be used to contaminate a waterhole, after which the disoriented emus were easy to catch. Another stratagem was for the hunter to use a skin as a disguise, and the birds could be lured into a camouflaged pit trap using rags or imitation calls. Aboriginal Australians only killed emus out of necessity, and frowned on anyone who hunted them for any other reason. Every part of the carcass had some use; the fat was harvested for its valuable, multiple-use oil, the bones were shaped into knives and tools, the feathers were used for body adornment and the tendons substituted for string.The early European settlers killed emus to provide food and used their fat for fuelling lamps. They also tried to prevent them from interfering with farming or invading settlements in search of water during drought. An extreme example of this was the Emu War in Western Australia in 1932. Emus flocked to the Chandler and Walgoolan area during a dry spell, damaging rabbit fencing and devastating crops. An attempt to drive them off was mounted, with the army called in to dispatch them with machine guns; the emus largely avoided the hunters. Emus are large, powerful birds, and their legs are among the strongest of any animal and powerful enough to tear down metal fencing. The birds are very defensive of their young, and there have been two documented cases of humans being attacked by emus.
+
+
+=== Economic value ===
+In the areas in which it was endemic, the emu was an important source of meat to Aboriginal Australians. They used the fat as bush medicine and rubbed it into their skin. It served as a valuable lubricant, was used to oil wooden tools and utensils such as the coolamon, and was mixed with ochre to make the traditional paint for ceremonial body adornment. Their eggs were also foraged for food.An example of how the emu was cooked comes from the Arrernte of Central Australia who called it Kere ankerre:
+
+Emus are around all the time, in green times and dry times. You pluck the feathers out first, then pull out the crop from the stomach, and put in the feathers you've pulled out, and then singe it on the fire. You wrap the milk guts that you've pulled out into something [such as] gum leaves and cook them. When you've got the fat off, you cut the meat up and cook it on fire made from river red gum wood.
+
+The birds were a food and fuel source for early European settlers, and are now farmed, in Australia and elsewhere, for their meat, oil and leather. Commercial emu farming started in Western Australia around 1970. The commercial industry in the country is based on stock bred in captivity, and all states except Tasmania have licensing requirements to protect wild emus. Outside Australia, emus are farmed on a large scale in North America, with about 1 million birds in the US, Peru, and China, and to a lesser extent in some other countries. Emus breed well in captivity, and are kept in large open pens to avoid the leg and digestive problems that arise from inactivity. They are typically fed on grain supplemented by grazing, and are slaughtered at 15 to 18 months.The Salem district administration in India advised farmers in 2012 not to invest in the emu business which was being heavily promoted at the time; further investigation was needed to assess the profitability of farming the birds in India. In the United States, it was reported in 2013 that many ranchers had left the emu business; it was estimated that the number of growers had dropped from over five thousand in 1998 to one or two thousand in 2013. The remaining growers increasingly rely on sales of oil for their profit, although, leather, eggs, and meat are also sold.
+
+Emus are farmed primarily for their meat, leather, feathers and oil, and 95% of the carcass can be used. Emu meat is a low-fat product (less than 1.5% fat), and is comparable to other lean meats. Most of the usable portions (the best cuts come from the thigh and the larger muscles of the drum or lower leg) are, like other poultry, dark meat; emu meat is considered for cooking purposes by the US Food and Drug Administration to be a red meat because its red colour and pH value approximate that of beef, but for inspection purposes it is considered to be poultry.
+Emu fat is rendered to produce oil for cosmetics, dietary supplements, and therapeutic products. The oil is obtained from the subcutaneous and retroperitoneal fat; the macerated adipose tissue is heated and the liquefied fat is filtered to get a clear oil. This consists mainly of fatty acids of which oleic acid (42%), linoleic and palmitic acids (21% each) are the most prominent components. It also contains various anti-oxidants, notably carotenoids and flavones.There is some evidence that the oil has anti-inflammatory properties; however, there have not yet been extensive tests, and the USDA regards pure emu oil as an unapproved drug and highlighted it in a 2009 article entitled "How to Spot Health Fraud". Nevertheless, the oil has been linked to the easing of gastrointestinal inflammation, and tests on rats have shown that it has a significant effect in treating arthritis and joint pain, more so than olive or fish oils. It has been scientifically shown to improve the rate of wound healing, but the mechanism responsible for this effect is not understood. A 2008 study has claimed that emu oil has a better anti-oxidative and anti-inflammatory potential than ostrich oil, and linked this to emu oil's higher proportion of unsaturated to saturated fatty acids. While there are no scientific studies showing that emu oil is effective in humans, it is marketed and promoted as a dietary supplement with a wide variety of claimed health benefits. Commercially marketed emu oil supplements are poorly standardised.
+
+Emu leather has a distinctive patterned surface, due to a raised area around the feather follicles in the skin; the leather is used in such items as wallets, handbags, shoes and clothes, often in combination with other leathers. The feathers and eggs are used in decorative arts and crafts. In particular, emptied emu eggs have been engraved with portraits, similar to cameos, and scenes of Australian native animals. Mounted Emu eggs and emu-egg containers in the form of hundreds of goblets, inkstands and vases were produced in the second half of the nineteenth century, all richly embellished with images of Australian flora, fauna and indigenous people by travelling silversmiths, founders of a 'new Australian grammar of ornament'. They continued longstanding traditions that can be traced back to the European mounted ostrich eggs of the thirteenth century and Christian symbolism and notions of virginity, fertility, faith and strength. For a society of proud settlers who sought to bring culture and civilisation to their new world, the traditional ostrich-egg goblet, freed from its roots in a society dominated by court culture, was creatively made novel in the Australian colonies as forms and functions were invented to make the objects attractive to a new, broader audience. Significant designers Adolphus Blau, Julius Hogarth, Ernest Leviny, Julius Schomburgk, Johann Heinrich Steiner, Christian Quist, Joachim Matthias Wendt, William Edwards and others had the technical training on which to build flourishing businesses in a country rich in raw materials and a clientele hungry for old-world paraphernalia.
+
+
+=== Cultural references ===
+
+The emu has a prominent place in Australian Aboriginal mythology, including a creation myth of the Yuwaalaraay and other groups in New South Wales who say that the sun was made by throwing an emu's egg into the sky; the bird features in numerous aetiological stories told across a number of Aboriginal groups. One story from Western Australia holds that a man once annoyed a small bird, who responded by throwing a boomerang, severing the arms of the man and transforming him into a flightless emu. The Kurdaitcha man of Central Australia is said to wear sandals made of emu feathers to mask his footprints. Many Aboriginal language groups throughout Australia have a tradition that the dark dust lanes in the Milky Way represent a giant emu in the sky. Several of the Sydney rock engravings depict emus, and the birds are mimicked in Indigenous dances. Hunting emus, known as kari in the Kaurna language, features in the major Dreaming story of the Kaurna people of the Adelaide region about the ancestor hero Tjilbruke.
+The emu is popularly but unofficially considered as a faunal emblem – the national bird of Australia. It appears as a shield bearer on the Coat of arms of Australia with the red kangaroo, and as a part of the Arms also appears on the Australian 50-cent coin. It has featured on numerous Australian postage stamps, including a pre-federation New South Wales 100th Anniversary issue from 1888, which featured a 2 pence blue emu stamp, a 36-cent stamp released in 1986, and a $1.35 stamp released in 1994. The hats of the Australian Light Horse are decorated with emu feather plumes.Trademarks of early Australian companies using the emu included Webbenderfer Bros frame mouldings (1891), Mac Robertson Chocolate and Cocoa (1893), Dyason and Son Emu Brand Cordial Sauce (1894), James Allard Pottery Wares (1906), and rope manufacturers G. Kinnear and Sons Pty. Ltd. still use it on some of their products.There are around six hundred gazetted places in Australia with "emu" in their title, including mountains, lakes, hills, plains, creeks and waterholes. During the 19th and 20th centuries, many Australian companies and household products were named after the bird. In Western Australia, Emu beer has been produced since the early 20th century and the Swan Brewery continues to produce a range of beers branded as "Emu". The quarterly peer-reviewed journal of the Royal Australasian Ornithologists Union, also known as Birds Australia, is entitled Emu: Austral Ornithology.The comedian Rod Hull featured a wayward emu puppet in his act for many years and the bird returned to the small screen in the hands of his son Toby after the puppeteer's death in 1999. In 2019, American insurance company Liberty Mutual launched an advertising campaign that features LiMu Emu, a CGI-rendered emu.Another popular Emu on social media is Emmanuel, a resident of Knuckle Bump Farms in south Florida.  Taylor Blake, an employee, since 2013 has recorded video shorts explaining aspects of the farm and is often interrupted as Emmanuel the Emu photobombs her videos earning constant rebukes; the term “Emmanuel don’t do it!” has become popular on social media.

+== Status and conservation ==

+In John Gould's Handbook to the Birds of Australia, first published in 1865, he lamented the loss of the emu from Tasmania, where it had become rare and has since become extinct; he noted that emus were no longer common in the vicinity of Sydney and proposed that the species be given protected status. In the 1930s, emu killings in Western Australia peaked at 57,000, and culls were also mounted in Queensland during this period due to rampant crop damage. In the 1960s, bounties were still being paid in Western Australia for killing emus, but since then, wild emus have been granted formal protection under the Environment Protection and Biodiversity Conservation Act 1999. Their occurrence range is between 4,240,000 and 6,730,000 km2 (1,640,000–2,600,000 sq mi), and a 1992 census suggested that their total population was between 630,000 and 725,000. Their population trend is thought to be stable and the International Union for Conservation of Nature assesses their conservation status as being of least concern. The isolated emu population of the New South Wales North Coast Bioregion and Port Stephens is listed as endangered by the New South Wales Government.Although the population of emus on mainland Australia is thought to be higher now than it was before European settlement, some local populations are at risk of extinction. The threats faced by emus include the clearance and fragmentation of areas of suitable habitat, deliberate slaughter, collisions with vehicles and predation of the eggs and young.

+The pied imperial pigeon (Ducula bicolor) is a relatively large, pied species of pigeon. It is found in forest, woodland, mangrove, plantations and scrub in Southeast Asia, ranging from Myanmar and Thailand, throughout Indonesia and east to the Philippines (where it is locally called as camasu and balud-puti) and the Bird's Head Peninsula in New Guinea. It is mainly found on small islands and in coastal regions. It remains locally common, and is therefore considered to be of least concern by BirdLife International and IUCN.
+
+
+== Taxonomy ==
+
+Its taxonomy is confusing and remains unsettled. It has sometimes included the Torresian, yellowish and silver-tipped imperial pigeons as subspecies. The widespread nominate subspecies of the pied imperial pigeon differs from all these by its plain white thighs and undertail coverts (though often with a dark spot at the very tip), and its narrowly dark-tipped bluish bill. For comparison, the other species' have black-spotted undertail coverts and thighs (spotting mainly near thighs in silver-tipped imperial pigeon), the bill of the Torresian imperial pigeon is greenish-yellow, and the bills of the yellowish and silver-tipped imperial pigeons are bluish at the base and yellowish at the tip. Furthermore, the yellowish imperial pigeon has a distinctive yellowish tinge to its plumage (some pied imperial pigeons may also appear yellowish, but infrequently to the same extent), and the silver-tipped imperial pigeon has silvery-grey remiges. However, the taxon melanura of the Moluccas, which usually is considered a subspecies of the pied imperial pigeon, resembles the Torresian imperial pigeon in bill, thighs and undertail coverts, but has a significantly broader black tail-tip. Consequently, some have suggested it should be placed under the Torresian imperial pigeon, while others have suggested it should be considered an entirely separate species, D. melanura (for which the name black imperial pigeon has been used – an unfortunate choice, as only the tail has significantly more black than the other members of this group, and the name black imperial pigeon usually has been used for D. melanochroa). Yet others have considered melanura to be invalid, instead believing it only is a morph of D. b. bicolor, as both types can be found on some islands.

+Dyscophus guineti, the false tomato frog or the Sambava tomato frog, is a species of frog in the family Microhylidae. It is endemic to Madagascar. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical swamps, swamps, freshwater marshes, intermittent freshwater marshes, and heavily degraded former forest. It is threatened by habitat loss.
+Description, The Dyscophus guineti male frogs are yellowish, and in size 60-65mm. The female frogs are red- orange often with many small reticulations, in size 90-95mm. Some of these frogs have an Odontoma which are tumors from a tooth that also contain tissue. These cause bad tooth eruption and displacement of erupted teeth. Another aspect which concerns these frogs is the way they capture their prey using their tongues and mouth.  It is based on how close their prey is to them, the way they capture it changes.  If their prey is smaller and at an azimuthal location of less than 40A degrees, they will aim their heads at the prey and not their tongues.  If their prey is larger and at an azimuthal location greater than 40A then they proceed to aim both their head and tongue at their prey.  The process when the prey is larger is better known as hydrostatic elongation.  The dysciphus guinteti also has tongue movements sperate of the lower jaw which changes their speed, momentum, and projection of their tongue in different situations.

+The red lory (Eos bornea) is a species of parrot in the family Psittaculidae. It is the second-most commonly kept lory in captivity, after the rainbow lorikeet.
+
+
+== Taxonomy ==
+In 1751 the English naturalist George Edwards included an illustration and a description of the red lory in the fourth volume of his A Natural History of Uncommon Birds. He used the English name "The long-tailed scarlet lory". Edwards based his hand-coloured etching on a stuffed specimen that he had purchased from a toyshop in London. He was uncertain of its origin. Edward gave his specimen to the collector Hans Sloane and subsequently a visitor to Sloane's house suggested that the bird may have come from Borneo. When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he placed the red lory with the other parrots in the genus Psittacus. Linnaeus included a brief description, coined the binomial name Psittacus borneus and cited Edwards' work. The red lory is now one of six species placed in the genus Eos that was introduced by the German naturalist Johann Georg Wagler in 1832. The genus name is from the Ancient Greek eōs meaning "dawn". The specific epithet borneus, bornea is a toponym from Borneo. This is an error as the species does not occur on the island.There is some uncertainty as to whether Edwards' plate actually depicts a red lory and the binomial name Eos rubra (Gmelin, 1788) has sometimes been used for this species.The word "lory" comes from the Malay lūri, a name used for a number of species of colourful parrots. The name was used by the Dutch writer Johan Nieuhof in 1682 in a book describing his travels in the East Indies. The spelling "laurey" was used by English naturalist Eleazar Albin in 1731 for a species of parrot from Brazil, and then in 1751 Edwards used the spelling "lory" for five species of parrot from the East Indies. Edwards credited Nieuhof for the name.Two subspecies are recognised:
+E. b. cyanonotha (Vieillot, 1818) – Buru (central Maluku Islands)
+E. b. bornea (Linnaeus, 1758) – south Maluku Islands and Kai Islands
+
+
+== Description ==
+ 
+The red lory is about 31 cm (12 in) long. They weigh 30-300 grams. It is mostly red and all the plumage of the upper body is red. There are red, blue, and black marks on the back and wings, and the tail is reddish-brown with blue under-tail coverts. The beak is orange and the legs are grey. The irises are red except in E. b. bernsteini, which has brown irises. There is no bare skin at the base of the lower mandible. The male and female have identical external appearance. Juveniles are duller and have brown irises and a brownish beak. Their bills are narrower and less powerful than other types of parrots and their gizzards are generally thin-walled and weak. A defining characteristic of a Lory is their brush tongues with papillae at the tips to help them feed on pollen and nectar.
+
+
+== Distribution and habitat ==
+Lories and lorikeets live in Indonesia, New Guinea, Australia and the Pacific. The red lory in particular is endemic to the Moluccas and surrounding islands in Indonesia. Its natural habitats are tropical moist lowland forests and tropical mangrove forests.
+It also was introduced to Taiwan.
+
+
+== Aviculture ==
+This intelligent bird has a playful personality and a colourful appearance. They are often described as flamboyant, theatrical and pugnacious birds. The subspecies, Buru red lory (Eos bornea cyanonothus) is darker, more maroon in colour, and is often confused in captivity with the nominate. Inadvertent interbreeding between the two subspecies has made a clear identification difficult for pet owners as hybrids can be found. The other two subspecies are not as common, Rothschild's red lory (Eos bornea rothschildi) and Bernstein's red lory (Eos bornea bernsteini). Lories are very intelligent, trainable, affectionate, playful and curious and they can display interesting behaviors. For example, some lories have wrapped themselves in a washcloth for sleeping or some sleep on their backs with their feet up in the air. When kept as a pet, they should be given toys (ropes, bells, balls, swings), chewing items and branches. They require much attention and care. They should be bathed frequently in a bird bath, bowl or shower, and they can be dried by the sun or by a blow drier. A moderate amount of their feathers should be clipped to prevent them from flying. Young birds must be socialized and exposed to new people and new things (new cages, toys, vet visits, wing and nail clippings). Outdoor housing is preferred, but if housed in cages, the cages must be large and cleaned often. They may be kept alone or with others, as long as they are closely monitored for signs of aggression. Mated pairs defend their territories forcefully.
+
+
+== Diet ==
+In the wild, lories eat nectar, pollen, fruits, and occasional insects. As pets they should be fed a good formulated diet. Smaller lories should be fed fresh nectar (commercial or home-made) daily. Larger birds can be fed pellets from a bird food company, or fruits and vegetables such as apples, pomegranates, papaya, grapes, cantaloupe, pineapple, figs, kiwi, and corn-on-the-cob. Lories can be given treats to reward positive behavior. Fresh, clean water should be provided daily.

+The blue-streaked lory (Eos reticulata) is also known as the blue-necked lory. It is a medium-sized parrot (31 cm), which is found on the Tanimbar Islands and Babar in the southern Moluccas.
+
+
+== Appearance ==
+The blue-streaked lory is about 31 centimetres (12 in) in length, including the tail. They weigh between 145 and 155 grams (5.1 and 5.5 oz).Adults of both sexes look the same – this is called sexually monomorphic.Most of the bird's general plumage is bright red. Against this intense red background, there are scattered electric blue feathers near the ears and on the nape of the neck, which is where the bird gets its name. From the area to the base of the neck, there is an indigo-violet stripe. The lower part of the nape of the neck, to the top of the back, is a bluish black. The main part of the back, as well as the rump, is red. Wing coverts and flights are red with black tips. The upper part of the tail feathers are a reddish black, and the underside of the tail is a muted red. The iris of the eye is orange-red. The beak is sharply curved, short, and bright red-orange. The feet are medium gray, and the claws are black.
+
+
+== Social ecology ==
+There are estimated to be between 100,000 and 500,000 blue-streaked lories in the wild.While their diet in the wild is unknown, it is thought to be similar to that of most lories and lorikeets, with pollen, nectar, fruit, and some insects making up the vast bulk of the ingesta.These lories are known as one of the louder species, and when kept in captivity, people's neighbors who desire quiet might be disturbed or annoyed by the bird's penetrating voice. The call is described as a shrill series of screeches in succession, or singular screeches.Social and gregarious, these birds travel in noisy flocks of up to ten individuals when possible.The bird's lifespan in captivity is reported to be 28–32 years.The usual clutch of eggs is 2, but in exceptional circumstances, 3 eggs may be laid. In commercial aviculture for breeding, it is very important to set up compatible pairs, to prevent harm to one member of the pair.Incubation time is 25 days, and from the time of hatching, the time to fledge is approximately 12 weeks.
+
+
+== Threats ==
+Main threats to the bird in the wild are habitat degradation (logging, forest extirpation to plant palms or other monocultures) and trapping for the pet trade.The birds have a restricted and small range, but because the population is not fragmented, it is not severely threatened.Both primary, old growth forest and replacement, or secondary, forest are preferred habitats. These parrots will live in mangrove forests as well as on human managed lands such as coconut plantations.
+
+
+== Legal status ==
+The IUCN lists these parrots as Near Threatened. For international trade, this parrot is listed as CITES Appendix II, which means that commercial trade must be done with special permits.
+
+
+== Relationship with humans ==
+The bird is tame and playful when they have been raised by humans in captivity. Wild caught birds, being wild, are shy. The bird readily adapts to life in captivity.
+
+
+== Taxonomic note ==
+There are no subspecies; only the nominate race is recognized.

+Grévy's zebra (Equus grevyi), also known as the imperial zebra, is the largest living wild equid and the most threatened of the three species of zebra, the other two being the plains zebra and the mountain zebra. Named after Jules Grévy, it is found in parts of Kenya, Somalia and Ethiopia. Superficially, Grévy's zebras’ physical features can help to identify it from the other zebra species; their overall appearance is slightly closer to that of a mule, compared to the more “equine” (horse) appearance of the plains and mountain zebras. Compared to other zebra species, Grévy’s are the tallest; they have mule-like, larger ears, and have the tightest stripes of all zebras. They have distinctively erect manes, and more slender snouts.
+The Grévy's zebra live in semi-arid savanna, where they feed on grasses, legumes, and browse, such as acacia; they can survive up to five days without water. They differ from the other zebra species in that they do not live in a harem, and they maintain few long-lasting social bonds. Stallion territoriality and mother–foal relationships form the basis of the social system of the Grévy's zebra. Despite a handful of zoos and animal parks around the world having had successful captive-breeding programs, in its native home this zebra is listed by the IUCN as endangered. Its population has declined from 15,000 to 2,000 since the 1970s. In 2016, the population was reported to be “stable”; however, as of 2020, the wild numbers are still estimated at only around 2,250 animals, in part due to anthrax outbreaks in eastern Africa.
+
+
+== Taxonomy and naming ==
+The Grévy's zebra was first described by French naturalist Émile Oustalet in 1882. He named it after Jules Grévy, then president of France, who, in the 1880s, was given one by the government of Abyssinia. Traditionally, this species was classified in the subgenus Dolichohippus with plains zebra and mountain zebra in Hippotigris. Groves and Bell (2004) place all three species in the subgenus Hippotigris.Fossils of zebra-like equids have been found throughout Africa and Asia in the Pliocene and Pleistocene deposits. Notable examples include E. sanmeniensis from China, E. cautleyi from India, E. valeriani from central Asia and E. oldowayensis from East Africa. The latter, in particular is very similar to the Grévy's zebra and may have been its ancestor. 
+The modern Grévy's zebra arose in the Middle Pleistocene. Zebras appear to be a monophyletic lineage and recent (2013) phylogenies have placed Grevy's zebra in a sister taxon with the plains zebra. In areas where Grévy's zebras are sympatric with plains zebras, the two may gather in same herds and fertile hybrids do occur.
+
+
+== Description ==
+
+The Grévy's zebra is the largest of all wild equines. It is 2.5–2.75 m (8.2–9.0 ft) in head-body with a 55–75 cm (22–30 in) tail, and stands 1.45–1.6 m (4.8–5.2 ft) high at the withers. These zebras weigh 350–450 kg (770–990 lb). Grévy's zebra differs from the other two zebras in its more primitive characteristics.: 147  It is particularly mule-like in appearance; the head is large, long, and narrow with elongated nostril openings;: 147  the ears are very large, rounded, and conical and the neck is short but thick. The zebra's muzzle is ash-grey to black in colour with the lips having whiskers. The mane is tall and erect; juveniles have a mane that extends to the length of the back and shortens as they reach adulthood.As with all zebra species, the Grevy's zebra's pelage has a black and white striping pattern. The stripes are narrow and close-set, being broader on the neck, and they extend to the hooves. The belly and the area around the base of the tail lack stripes and are just white in color, which is unique to the Grevy's zebra. Foals are born with brown and white striping, with the brown stripes darkening as they grow older.
+
+
+== Range and ecology ==
+
+The Grévy's zebra largely inhabits northern Kenya, with some isolated populations in Ethiopia.: 147  It was extirpated from Somalia and Djibouti and its status in South Sudan is uncertain. It lives in Acacia-Commiphora bushlands and barren plains. Ecologically, this species is intermediate between the arid-living African wild ass and the water-dependent plains zebra.: 147  Lactating mares and non-territorial stallions use areas with green, short grass and medium, dense bush more often than non-lactating mares and territorial stallions.Grévy's zebras rely on grasses, legumes, and browse for nutrition. They commonly browse when grasses are not plentiful. Their hindgut fermentation digestive system allows them to subsist on diets of lower nutritional quality than that necessary for ruminant herbivores. Grevy's zebras can survive up to a week without water, but will drink daily when it is plentiful. They often migrate to better watered highlands during the dry season. Mares require significantly more water when they are lactating. During droughts, the zebras will dig water holes and defend them. The Grévy's zebra's main predator is the lion, but adults can be hunted by spotted hyenas. African hunting dogs, cheetahs and leopards almost never attack adults, even in desperate times, but sometimes prey on young animals, although mares are fiercely protective of their young. In addition, they are susceptible to various gastro-intestinal parasites, notably of the genus Trichostrongylus.
+
+
+== Behaviour and life history ==
+
+Adult stallions mostly live in territories during the wet seasons but some may stay in them year round if there's enough water left. Stallions that are unable to establish territories are free-ranging: 151  and are known as bachelors. Mares, young and non-territorial stallions wander through large home ranges. The mares will wander from territory to territory preferring the ones with the highest-quality food and water sources. Up to nine stallions may compete for a mare outside of a territory. Territorial stallions will tolerate other stallions who wander in their territory. However, when an oestrous mare is present the territorial stallion keeps other stallions at bay.: 151  Non-territorial stallions might avoid territorial ones because of harassment. When mares are not around, a territorial stallion will seek the company of other stallions. The stallion shows his dominance with an arched neck and a high-stepping gait and the least dominant stallions submit by extending their tail, lowering their heads and nuzzling their superior's chest or groin.: 151 Zebras produce numerous sounds and vocalisations. When alarmed, they produce deep, hoarse grunts. Whistles and squeals are also made when alarmed, during fights, when scared or in pain. Snorts may be produced when scared or as a warning. A stallion will bray in defense of his territory, when driving mares, or keeping other stallions at bay. Barks may be made during copulation and distressed foals will squeal. The call of the Grévy's zebra has been described as "something like a hippo's grunt combined with a donkey's wheeze". To get rid of flies or parasites, they roll in dust, water or mud or, in the case of flies, they twitch their skin. They also rub against trees, rocks and other objects to get rid of irritations such as itchy skin, hair or parasites. Although Grévy's zebras do not perform mutual grooming, they do sometimes rub against a conspecific.
+
+
+=== Reproduction ===
+
+Grévy's zebras can mate and give birth year round, but most mating takes place in the early rainy seasons and births mostly take place in August or September after the long rains. An oestrous mare may visit as many as four territories a day and will mate with the stallions in them. Among territorial stallions, the most dominant ones control territories near water sources, which mostly attract mares with dependant foals, while more subordinate stallions control territories away from water with greater amounts of vegetation, which mostly attract mares without dependant foals.
+
+The resident stallions of territories will try to subdue the entering mares with dominance rituals and then continue with courtship and copulation. Grévy's zebra stallions have large testicles and can ejaculate a large amount of semen to replace the sperm of other males. This is a useful adaptation for a species whose mares mate polyandrously. Bachelors or outside territorial stallions sometimes "sneak" copulation of mares in another stallion's territory. While mare associations with individual stallions are brief and mating is promiscuous, mares who have just given birth will reside with one stallion for long periods and mate exclusively with that stallion. Lactating females are harassed by stallions more often than non-lactating ones and thus associating with one male and his territory provides an advantage as he will guard against other males.Gestation of the Grévy's zebra normally lasts 390 days, with a single foal being born. A new-born zebra will follow anything that moves, so new mothers prevent other mares from approaching their foals while imprinting their own striping pattern, scent and vocalisation on them. Mares with young foals may gather into small groups. Mares may leave their foals in "kindergartens" while searching for water. The foals will not hide, so they can be vulnerable to predators. However, kindergartens tend to be protected by an adult, usually a territorial stallion. A mare with a foal stays with one dominant territorial stallion who has exclusive mating rights to her. While the foal may not be his, the stallion will look after it to ensure that the mare stays in his territory. To adapt to a semi-arid environment, Grévy's zebra foals have longer nursing intervals and wait until they are three months old before they start drinking water. Although offspring become less dependent on their mothers after half a year, associations with them continue for up to three years.
+
+
+== Relationship with humans ==
+
+The Grévy's zebra was known to the Europeans in antiquity and was used by the Romans in circuses. It was subsequently forgotten in the Western world for a thousand years. In the seventeenth century, the king of Shoa (now central Ethiopia) exported two zebras; one to the Sultan of Turkey and another to the Dutch governor of Jakarta. A century later, in 1882, the government of Abyssinia sent one to French president Jules Grévy. It was at that time that the animal was recognised as its own species and named in Grévy's honour.
+
+
+=== Status and conservation ===
+
+The Grévy's zebra is considered endangered. Its population was estimated to be 15,000 in the 1970s and by the early 21st century the population was lower than 3,500, a 75% decline.: 11  In 2008 it was estimated that there are less than 2,500 Grévy's zebras still living in the wild, further declining to fewer than 2,000 mature individulas in 2016. Nonetheless, the Grévy's zebra population trend was considered stable as of 2016.There are also an estimated 600 Grévy's zebras in captivity.: 20  Captive herds have been known to thrive, like at White Oak Conservation in Yulee, Florida, United States, where more than 70 foals have been born. There, research is underway in partnership with the Conservation Centers for Species Survival on semen collection and freezing and on artificial insemination.The Grévy's zebra is legally protected in Ethiopia. In Kenya, it is protected by the hunting ban of 1977. In the past, Grévy's zebras were threatened mainly by hunting for their skins which fetched a high price on the world market. However, hunting has declined and the main threat to the zebra is habitat loss and competition with livestock. Cattle gather around watering holes and the Grévy's zebras are fenced from those areas.: 17  Community-based conservation efforts have shown to be the most effective in preserving Grévy's zebras and their habitat. Less than 0.5% of the range of the Grévy's zebra is in protected areas. In Ethiopia, the protected areas include Alledeghi Wildlife Reserve, Yabelo Wildlife Sanctuary, Borana National Park, and Chelbi Sanctuary. In Kenya, important protected areas include the Buffalo Springs, Samburu and Shaba National Reserves and the private and community land wildlife conservancies in Isiolo, Samburu and the Laikipia Plateau.The mesquite plant was introduced into Ethiopia around 1997 and is endangering the zebra's food supply. An invasive species, it is replacing the two grass species, Cenchrus ciliaris and Chrysopogon plumulosus, which the zebras eat for most of their food.

+The scarlet ibis (Eudocimus ruber) is a species of ibis in the bird family Threskiornithidae. It inhabits tropical South America and part of the Caribbean. In form, it resembles most of the other twenty-seven extant species of ibis, but its remarkably brilliant scarlet coloration makes it unmistakable. It is one of the two national birds of Trinidad and Tobago, and its Tupi–Guarani name, guará, is part of the name of several municipalities along the coast of Brazil.This medium-sized wader is a hardy, numerous, and prolific bird, and it has protected status around the world.  Its IUCN status is Least Concern. The legitimacy of Eudocimus ruber as a biological classification, however, is in dispute. Traditional Linnaean taxonomy classifies it as a unique species, but some scientists have moved to reclassify it as a subspecies of a more general American ibis species, along with its close relative, the American white ibis (Eudocimus albus).
+
+
+== Taxonomy ==
+The species was first classified by Carl Linnaeus in 1758. Initially given the binomial nomenclature of  Scolopax rubra (the name incorporates the Latin adjective ruber, "red"), the species was later designated Guara rubra and ultimately Eudocimus ruber.Biologically the scarlet ibis is very closely related to the American white ibis (Eudocimus albus) and is sometimes considered conspecific with it, leaving modern science divided over their taxonomy. The two birds each have exactly the same bones, claws, beaks, feather arrangements and other features – their one marked difference lies in their pigmentation. Traditional taxonomy has regarded the two as separate and distinct.Early ornithological field research revealed no natural crossbreeding among the red and white, lending support to the two-species viewpoint. More recent observation, however, has documented significant crossbreeding and hybridization in the wild. Researchers Cristina Ramo and Benjamin Busto found evidence of interbreeding in a population where the ranges of the scarlet and white ibises overlap along the coast and in the Llanos in Colombia and Venezuela. They observed individuals of the two species mating and pairing, as well as hybrid ibises with pale orange plumage, or white plumage with occasional orange feathers, and have proposed that these birds be classified as a single species. Hybridization has been known to occur frequently in captivity. However, the two color forms persist in the wild despite overlapping ranges and hybrid offspring having a distinctive color type, so according to the cohesion species concept they would be functionally different species.Some biologists now wish to pair them with Eudocimus albus as two subspecies of the same American ibis. Others simply define both of them as one and the same species, with ruber being a color variation of albus.
+
+
+== Description ==
+
+Adult plumage is virtually all scarlet. The feathers may show various tints and shades, but only the tips of their wings deviate from their namesake color. A small but reliable marking, these wingtips are a rich inky black (or occasionally dark blue) and are found only on the longest primaries – otherwise the birds' coloration is "a vivid orange-red, almost luminous in quality." Scarlet ibises have red bills and feet however the bill is sometimes blackish, especially toward the end. They have a long, narrow, decurved bill. Their legs and neck are long and extended in flight.A juvenile scarlet ibis is a mix of grey, brown, and white. As it grows, a heavy diet of red crustaceans produces the scarlet coloration. The color change begins with the juvenile's second moult, around the time it begins to fly: the change starts on the back and spreads gradually across the body while increasing in intensity over a period of about two years. The scarlet ibis is the only shorebird with red coloration in the world.
+Adults are 55–63 centimetres (22–25 in) long, and the males, slightly larger than females, typically weigh about 1.4 kilograms (3.1 lb). Their bills are also on average around 22% longer than those of females. The life span of the scarlet ibis is approximately sixteen years in the wild and twenty years in captivity. An adult scarlet ibis has a wingspan of around 54 centimetres (21 in). Though it spends most of its time on foot or wading through water, the bird is a very strong flyer: they are highly migratory and easily capable of long-distance flight. They move as flocks in a classic V formation.
+
+
+== Distribution and habitat ==
+
+The range of the scarlet ibis is very large, and colonies are found throughout vast areas of South America and the Caribbean islands. Native flocks exist in Brazil; Colombia; French Guiana; Guyana; Suriname; and Venezuela, as well as the islands of the Netherlands Antilles, and Trinidad and Tobago. Flocks gather in wetlands and other marshy habitats, including mud flats, shoreline and rainforest. Outlying colonies have been identified in the coastal areas of the states of Espírito Santo, Rio de Janeiro, São Paulo (for example in the Santos-Cubatão mangroves of the Baixada Santista district), Paraná and  Santa Catarina. In recent years, bird colonies can be seen as far south as in the coastal areas of Joinville and the island of São Francisco do Sul.The highest concentrations are found in the Llanos region of western Venezuela and eastern Colombia. The fertile and remote tropical grassland plain of the Llanos provides a safe haven far from human encroachment. Together with its relative the bare-faced ibis, the scarlet ibis is remarkably prolific and conspicuous in the region.Scarlet ibis vagrants have been identified in Belize, Ecuador, and Panama; Aruba, Cuba, Dominica, Grenada, and Jamaica; sightings have even been made in the United States. The species may well have been a natural vagrant to the Gulf Coast in the 19th century or earlier – in The Birds of America, John James Audubon made brief remarks regarding three rubra specimens he encountered in Louisiana. However, virtually all modern occurrences of the species in North America have been introduced or escaped birds. In one notable example from 1962, scarlet ibis eggs were placed in white ibis nests in Florida's Greynolds Park, and the resulting population hybridised easily, producing "pink ibises" that are still occasionally seen.
+
+
+== Behavior ==
+
+
+=== Breeding ===
+
+Mating pairs build nests in a simple style, typically "loose platforms of sticks" of a quality sometimes described as "artless". They roost in leaf canopies, mostly preferring the convenient shelter of young waterside mangrove trees. Scarlet ibises like wet, muddy areas such as swamps, but for safety they build their nests in trees well above the water. If they can, they nest on islands, where their eggs and chicks are less likely to be in danger from predators.To attract a female, the male will perform a variety of mating rituals such as "preening, shaking, bill popping, head rubbing, and high flights. As with most birds, mating does not involve any coupling or insertion: instead, a transfer of seminal fluids occurs during external contact between the cloacal openings. After a gestation period of five to six days, the female lays a clutch of three to five smooth, matte eggs which typically incubate for 19–23 days. After a successful courtship, pairs remain faithful and cohabitant, sharing parental responsibilities for the young.In southeastern Brazil, the ibises gather in colonies in mid-September and build nests at the beginning of November. Egg laying within the colony was synchronous, with female birds laying eggs in three waves in early November, late December and late January.
+
+
+=== Feeding ===
+Their distinctive long, thin bills are used to probe for food in soft mud or under plants. Popularly imagined to be eating only shrimp, a recent study in the Llanos has found that much of their diet consists of insects, of which the majority were scarabs and ground beetles. One species in particular, a scarab beetle Dyscinetus dubius, formed a large part of the diet. Other insect prey include water beetles and water bugs. In contrast, the diet of the co-occurring American white ibis there differed, the latter consuming more bugs, fish and crustaceans.
+
+They do, however, eat much shrimp and other similar fare like small crabs, mollusks and other crustaceans, such as crayfish. The large quantity of shrimp and other red shellfish produces a surfeit of astaxanthin, a carotenoid which is the key component of the birds' red pigmentation. Frogs, small snakes, small fish, fruits and seeds are also occasional prey items for scarlet ibises. When kept in zoos, the birds' diet often contains beetroot and carrot supplement to maintain color vibrancy in their plumage.The Llanos are notable in that these wetland plains support seven species of ibis in the one region. Here, scarlet ibis are the most aggressive, and attack other species to steal their food. They have also been observed trailing white-faced whistling ducks (Dendrocygna viduata) and domestic livestock, and catching insects disturbed by them.
+
+
+=== Social behavior ===
+The scarlet ibis is a sociable and gregarious bird, and very communally-minded regarding the search for food and the protection of the young. They live in flocks of thirty or more. Members stay close, and mating pairs arrange their nests in close proximity to other pairs in the same tree.For protection, flocks often congregate in large colonies of several thousand individuals. They also regularly participate in mixed flocks, gaining additional safety through numbers: storks, spoonbills, egrets, herons and ducks are all common companions during feedings and flights.
+
+
+== Status ==
+The species has protected status throughout the world, and the International Union for Conservation of Nature has classified the scarlet ibis as a species of Least Concern on the IUCN Red List. Though several local populations appear to be in decline, global totals remain relatively large and the current rate of losses is not considered a threat to the species' survival. Nonetheless, recent losses by established populations in French Guiana have become a concern for conservationists, and in Brazil the bird has been included on a national list of endangered species.
+
+
+=== Relationship with humans ===
+The scarlet ibis and the cocrico are the national birds of Trinidad and Tobago. Both birds are featured on the coat of arms of Trinidad and Tobago. The cocrico is found on Tobago, Venezuela and Colombia. The scarlet ibis is associated with Trinidad; there are not documented records of the scarlet ibis on Tobago for the last fifteen years.An important local habitat for the scarlet ibis is the wildlife sanctuary of Caroni Swamp of Trinidad, a 199 hectares (490 acres) wetland reserve first designated in 1953 specifically to provide a habitat for the scarlet ibis.Using the bird as a literary symbol, American author James Hurst composed a popular short story, "The Scarlet Ibis" (1960). A more recent short story, "Scarlet Ibis" by Margaret Atwood, is included in Bluebeard's Egg (1983). The name also belongs to a book of verse by American poet Susan Hahn.

+The black lemur (Eulemur macaco) is a species of lemur from the family Lemuridae.  Like all lemurs, it is endemic to Madagascar. Originally, the species was thought to have two subspecies, Eulemur macaco macaco and Eulemur macaco flavifrons, both of which were elevated to species status by Mittermeier et al. in 2008 to Eulemur macaco and Eulemur flavifrons respectively. The most startling difference between the two species is the eye colour; Eulemur flavifrons, the blue-eyed black lemur, has blue eyes, while Eulemur macaco, the black lemur, has brown or orange eyes, and also has ear tufts.Both species live in northwest Madagascar. The black lemur occurs in moist forests in the Sambirano region of Madagascar and on nearby islands. The blue-eyed black lemur is restricted to the Sahamalaza Peninsula and adjacent forests. There are reports of the two species hybridizing where their ranges overlap in Manongarivo Special Reserve.
+
+
+== Physical description ==
+
+The black lemur is between 90 and 110 centimeters in length, of which 51–65 centimeters are tail. Weight typically ranges between 1.8 and 2.0 kilograms. The black lemur displays sexual dimorphism in coloration. Males have black or dark chocolate fur, while females' fur is of a lighter brown color, generally medium brown, chestnut brown or even orange-brown. Males have large black ear tufts, while females have large white ear tufts.
+The only other Eulemur species that occurs within the range of the black lemur is the common brown lemur, which overlaps with the black lemur at the extreme southern and eastern edge of its range, and the red-bellied lemur, on the Tsaratanana Massif. The common brown lemur and the red-bellied lemur have different coloration and do not show the extreme sexual dimorphism of the black lemur, making confusion between the black lemur and the other species unlikely.
+
+
+== Diet ==
+
+The black lemur primarily eats fruit, which makes up an estimated 78% of its diet. The ripeness of this fruit is vital to the lemur's diet. Other foods eaten include flowers, leaves, fungi, some invertebrates and, especially during the dry season, nectar.
+
+
+== Behavior ==
+The black lemur lives in both primary and secondary forest. It is active both during the day and at night. It forages in both the upper and middle canopy, especially at night, and during the day it also forages in the understory. In degraded habitats, it also forages on the ground and may even eat soil.The black lemur lives in groups of 2 to 15 members, including approximately equal numbers of males and females. Average group size is about 10 members, although the average may be smaller for E. m. flavifrons. Females are dominant over males, although intragroup fighting is rare.Groups have home ranges of about 3.5 to 7 hectares. Ranges overlap considerably, and population density can reach 200 individuals per square kilometer.Black lemurs also have a habit of picking up and biting at toxic millipedes. The toxins are usually not fatal to the lemurs and they try to stimulate the millipede to release its toxins in self-defence. Once this is achieved the black lemur will rub the millipede around its body to get the toxins on its fur. It is believed that they do this to help repel insects with the millipedes poison.
+
+
+=== Reproduction ===
+Mating usually takes place in April and May. During mating season, antagonism between males increases, and males sometimes roam between groups. After a gestation of about 125 days, a single infant is usually born between late August and early October. Females typically give birth for the first time at two years of age.

+The yellow anaconda (Eunectes notaeus), also known as the Paraguayan anaconda, is a boa species endemic to southern South America. It is one of the largest snakes in the world but smaller than its close relative, the green anaconda. No subspecies are currently recognized. Like all boas and pythons, it is non-venomous and kills its prey by constriction.
+
+
+== Etymology ==
+
+The Neo-Latin specific name notaeus derives from Ancient Greek: νωταίος, romanized: nōtaios, lit. 'dorsal' (νωταίος is a poetic form of νωτιαίος/nōtiaios). In distinguishing his new species Eunectes notaeus from Eunectes murinus, Edward Drinker Cope stated, "Dorsal scales are larger and in fewer rows."
+
+
+== Description ==
+
+Adults grow to an average of 3.3 to 4.4 m (10.8 to 14.4 ft) in total length. Females are generally larger than males, and have been reported up to 4.6 m (15.1 ft) in length. They commonly weigh 25 to 35 kg (55 to 77 lb), but specimens weighing more than 55 kg (121 lb) have been observed. The color pattern consists of a yellow, golden-tan or greenish-yellow ground color overlaid with a series of black or dark brown saddles, blotches, spots and streaks.
+
+
+== Distribution and habitat ==
+The range of the yellow anaconda encompasses the drainage of the Paraguay River and its tributaries, from the Pantanal region in Bolivia, Paraguay, and western Brazil to northeastern Argentina and northern Uruguay.
+It prefers mostly aquatic habitats, including swamps, marshes, and brush-covered banks of slow-moving rivers and streams. The species appears to have been introduced in Florida, although it is unknown whether the small population (thought to derive from escaped pets) is reproductive.
+
+
+== Ecology ==
+The yellow anaconda forages predominantly in shallow water in wetland habitats. Most predation occurs from June to November, when flooding has somewhat subsided and wading birds are the most common prey. Observations and analysis of gut and waste contents from regularly flooded areas in the Pantanal region of southwestern Brazil indicate that they are generalist feeders that employ both ambush predation and wide-foraging strategies.
+Their prey consists nearly exclusively of aquatic or semi-aquatic species, including a wide variety of mammals, birds, reptiles, amphibians, fish and eggs. Larger specimens can prey upon larger animals, such as brocket deer, capybaras or peccaries. The prey-to-predator weight ratio is often much higher than for other types of Boidae. Cannibalism has been observed in this species, though it is not clear how often this occurs.The yellow anaconda has few predators. Juveniles and the occasional adult may be taken by caimans, larger anacondas, jaguars, cougars, some canids such as the crab-eating fox, mustelids, and raptors. The species is also hunted by humans for its skin.
+
+
+== Interactions with humans ==
+
+In captivity the species has a reputation for being unpredictable and somewhat dangerous to humans. In the United States, the import, transportation and sale of the species across state lines were banned in 2012 to try to prevent the yellow anaconda from becoming an invasive species in areas such as the Florida Everglades. The conservation status of the yellow anaconda has not been assessed by the IUCN.

+The Indian star tortoise (Geochelone elegans) is a threatened tortoise species native to India, Pakistan and Sri Lanka where it inhabits dry areas and scrub forest. It has been listed as Vulnerable on the IUCN Red List since 2016, as the population is thought to comprise more than 10,000 individuals, but with a declining trend. It is threatened by habitat loss and poaching for the illegal wildlife trade. It was upgraded to CITES Appendix I in 2019 by full consensus among all member states, giving it the highest level of international protection from commercial trade. Conservation group TRAFFIC found 6,040 were seized globally that were intended to be sold in the pet trade.
+
+
+== Anatomy and morphology ==
+The carapace of G. elegans is very convex, with dorsal shields often forming humps; the lateral margins are nearly vertical; the posterior margin is somewhat expanded and strongly serrated. It has no nuchal scute, and the supracaudal is undivided, and curved inward in the male; the shields are strongly striated concentrically. The first vertebral scute is longer than broad, and the others are broader than long, with the third at least as broad as the corresponding costal. The plastron is large, truncated or openly notched in front, and deeply notched and bifid behind; the suture between the humerals is much longer than that between the femorals; the suture between the pectorals is very short; the axillary and inguinal sutures are rather small. The head is moderate in size, with the forehead swollen, convex, and covered with rather small and irregular shields; the beak is feebly hooked, bi- or tricuspid; the edges of the jaws are denticulated; the alveolar ridge of the upper jaw is strong. The outer-anterior face of the fore limbs have numerous unequal-sized, large, imbricate, bony, pointed tubercles; the heel has large, more or less spur-like tubercles; a group of large conical or subconical tubercles is found on the hinder side of the thigh. The carapace is black, with yellow areolae from which yellow streaks radiate; these streaks are usually narrow and very numerous. The plastron likewise has black and yellow, radiating streaks. The Indian star tortoise can grow to 10 inches long.
+
+The patterning, although highly contrasting, is disruptive and breaks the outline of the tortoise as it sits in the shade of grass or vegetation. They are mostly herbivorous and feed on grasses, fallen fruit, flowers, and leaves of succulent plants, and will occasionally eat carrion. In captivity, however, they should never be fed meat.
+The sexual dimorphism of adult Indian star tortoises is quite apparent. Females are considerably larger than their male counterparts. In addition, the females' plastrons are much flatter than those of the males, which have a concave shape.
+The shape of this creature is presumed to be specially adapted to naturally assist it to return to a stable stance after it has been turned over. Mathematicians Gábor Domokos of the Budapest University of Technology and Economics and Péter Várkonyi of Princeton University designed a homogeneous object called a gömböc that has exactly one unstable balance point and exactly one stable balance point. Just as a bottom-weighted (nonhomogeneous weight distribution) sphere would always return to the same upright position, they found it was possible to construct a shape that behaves the same way. After that, they noted the similarity to the Indian star tortoise and subsequently tested 30 turtles by turning them upside down. They found many of them to be self-righting.
+
+
+== Distribution and habitat ==
+
+The Indian star tortoise ranges from India (except Lower Bengal), extending west to Sindh province (Pakistan) and Sri Lanka. A large number of specimens of this species are found in the illegal wildlife trade in India. Few studies exist which have quantified wild populations and the effect of trade on them.

+The northern bald ibis, hermit ibis, or waldrapp (Geronticus eremita) is a migratory bird found in barren, semi-desert or rocky habitats, often close to running water. This 70–80 cm (28–31 in) glossy black ibis, which, unlike many members of the ibis family, is non-wading, has an unfeathered red face and head, and a long, curved red bill. It breeds colonially on coastal or mountain cliff ledges, where it typically lays two to three eggs in a stick nest, and feeds on lizards, insects, and other small animals.
+The northern bald ibis was once widespread across the Middle East, northern Africa, southern and central Europe, with a fossil record dating back at least 1.8 million years. It disappeared from Europe over 300 years ago, although reintroduction programs in the region are underway. In 2019 there were about 700 wild birds remaining in southern Morocco, and fewer than 10 in Syria, where it was rediscovered in 2002 but where their number declined in the following years, maybe to zero.
+To combat these low numbers, reintroduction programs have been instituted internationally in recent times, with a semi-wild breeding colony in Turkey which counted almost 250 birds in 2018 as well as sites in Austria, Italy, Spain, and northern Morocco. These programs and the natural growth in Morocco from about 200 birds in the 1990s helped to downlist the northern bald ibis from Critically Endangered to Endangered on the IUCN Red List in 2018. There are about 2000 northern bald ibises living in captivity.
+The reasons for the species' long-term decline are unclear, but hunting, loss of foraging habitat, and pesticide poisoning have been implicated in the rapid loss of colonies in recent decades.
+
+
+== Taxonomy ==
+The ibises are gregarious, long-legged wading birds with long down-curved bills. Along with the spoonbills they form one subfamily within the family Threskiornithidae. The northern bald ibis' closest relative, and the only other member of the genus, is the southern bald ibis, G. calvus, of southern Africa. The two Geronticus species differ from other ibises in that they have unfeathered faces and heads, breed on cliffs rather than in trees, and prefer arid habitats to the wetlands used by their relatives.
+
+The northern bald ibis was described and illustrated by Swiss naturalist Conrad Gesner in his Historiae animalium in 1555, and given the binomial name Upupa eremita by Carl Linnaeus in his 1758 Systema Naturae. It was moved to its current genus by the German herpetologist Johann Georg Wagler in 1832. This species has an interesting history of description, oblivion and rediscovery.The species probably split into two distinct populations at least 400 years ago and, since then, the two populations have been diverging morphologically, ecologically, and genetically; nevertheless, the Turkish and Moroccan populations of this ibis are not currently classed as separate subspecies. One consistent difference between the eastern and western birds is a single mutation in the cytochrome b gene of their mitochondrial DNA.Fossils of the northern bald ibis have been found at a Holocene (c. 10,000 years ago) site in southern France, in middle Pleistocene (c. 900,000 years ago) strata in Sicily, and in Pliocene-Pleistocene boundary (c. 1.8 million years ago) deposits on the Mediterranean coast of Spain. What appears to be an ancestral form, Geronticus balcanicus, was found in the late Pliocene of Bulgaria, further illustrating the early widespread presence of this genus in Europe, and suggesting that Geronticus eremita may have originated in southeastern Europe or the Middle East.The genus name, Geronticus, is derived from the Ancient Greek γέρων, meaning old man and refers to the bald head of the aged. Eremita is Late Latin for hermit, from the Greek ἐρημία, meaning desert, and refers to the arid habitats inhabited by this species. The alternative common name waldrapp is German for forest raven, the equivalent of the Latin Corvo sylvatico of Gesner, adapted as Corvus sylvaticus by Linnaeus.
+
+
+== Description ==
+
+The northern bald ibis is a large, glossy black bird, 70–80 cm (28–31 in) long with a 125–135 cm (49–53 in) wingspan and an average weight of 1.0–1.3 kg (35–46 oz). The plumage is black, with bronze-green and violet iridescence, and there is a wispy ruff on the bird's hind neck. The face and head are dull red and unfeathered, and the long, curved bill and the legs are red. In flight, this bird has powerful, shallow, and flexible wing beats. It gives guttural hrump and high, hoarse hyoh calls at its breeding colonies, but is otherwise silent.The sexes are similar in plumage, although males are generally larger than females, and, as with other ibises that breed in colonies, have longer bills. The longer-billed males are more successful in attracting a mate. The downy chick has uniformly pale brown plumage, and the fledged juvenile resembles the adult except that it has a dark head, light grey legs, and a pale bill. The unfeathered areas of the young bird's head and neck gradually become red as it matures. Moroccan birds have a significantly longer bill than Turkish birds of the same sex.
+If the eastern and western populations are considered to be separable subspecies, it is unclear which should be considered to be the nominate (first-named) form, since the first description of this species was based on a now-extinct population from Switzerland which is of unknown race.The northern bald ibis is readily distinguished from its close relative, the southern bald ibis of Southern Africa, by the southern species' whitish face. The northern bald can also be confused with the similarly dark-plumaged glossy ibis, which overlaps its range, but it is larger and stockier than that species. In flight, when the bill and face colouration may not be visible, the bald ibis' less rounded wings and shorter neck give it a different profile from glossy ibis, and its relatively short legs mean that its feet do not project beyond the tail, unlike those of the glossy ibis.
+
+
+== Habitat and range ==
+
+Unlike many other ibises, which nest in trees and feed in wetlands, the northern bald ibis breeds on undisturbed cliff ledges, and forages for food in irregularly cultivated, grazed dry areas such as semi-arid steppes, and fallow fields. The close proximity of adequate steppe feeding areas to breeding cliffs is an important habitat requirement.The northern bald ibis was once widespread across the Middle East, northern Africa, and southern and central Europe; fossil bones have been found at Solothurn dated to the Mesolithic and Neolithic Periods. It bred along the Danube and Rhone Rivers, and in the mountains of Spain, Italy, Germany, Austria and Switzerland (Gesner's original description was of a Swiss bird), and most probably also in the Upper Adriatic region.  It used castle battlements as well as cliff ledges for nesting before vanishing from Europe at least three centuries ago. It is also extinct over most of its former range, and now almost the entirety of the wild breeding population of just over 500 birds is in Morocco, at Souss-Massa National Park, where there are three documented colonies, and near the mouth of the Oued Tamri (north of Agadir), where there is a single colony containing almost half the Moroccan breeding population. There is some movement of birds between these two sites.Religious traditions helped this species to survive in one Turkish colony long after the species had disappeared from Europe, since it was believed that the ibis migrated each year to guide Hajj pilgrims to Mecca. The ibis was protected by its religious significance, and a festival was held annually to celebrate its return north. The Turkish ibis population was centred near the small town of Birecik in the southeast of the country, and during the first half of the 20th century, the Birecik colony maintained a relatively stable population of about 500 breeding pairs, reaching an estimated total population of about 3,000 around 1930. By the 1970s, numbers had drastically declined and a captive breeding program was initiated in 1977 with one adult pair and nine chicks taken from the wild. This program largely failed to revert the decline; there were 400 birds in 1982, five pairs in 1986, and seven pairs in 1987. Only three birds returned from their wintering grounds in 1989, and just one in 1990. The returning birds died before they could reproduce, thus rendering the species extinct in the wild in Turkey as of 1992. Once the wild Turkish population became non-viable, the colony was maintained as a flock which was free-flying for most of the year but caged in autumn to prevent migration.
+
+After the demise of the migratory Turkish colony, the northern bald ibis was known to survive in the wild only at the Moroccan sites, although occasional sightings of birds in Yemen, Eritrea, Saudi Arabia, and Israel during the 1980s and 1990s suggested that there was still a colony somewhere in the Middle East. Intensive field surveys in spring 2002, based on the knowledge of Bedouin nomads and local hunters, revealed that the species had never become completely extinct on the Syrian desert steppes. Following systematic searches, 15 old nesting sites were found, one, near Palmyra, was still hosting an active breeding colony of seven individuals. Although the ibis had been declared extinct in Syria more than 70 years earlier, the bird appears to have been relatively common in the desert areas until 20 years ago, when a combination of overexploitation of its range lands and increasing hunting pressures initiated a dramatic decline.The Moroccan breeding birds are resident, dispersing along the coast after the nesting season. It has been suggested that coastal fog provides extra moisture for this population, and enables the ibises to remain year-round. In the rest of its former range, away from the Moroccan coastal locations, the northern bald ibis migrated south for the winter, and formerly occurred as a vagrant to Spain, Iraq, Egypt, the Azores, and Cape Verde.
+
+Satellite tagging of 13 Syrian birds in 2006 showed that the three adults in the group, plus a fourth untagged adult, wintered together from February to July in the highlands of Ethiopia, where the species had not been recorded for nearly 30 years. They travelled south on the eastern side of the Red Sea via Saudi Arabia and Yemen, and returned north through Sudan and Eritrea.
+
+
+== Behaviour ==
+
+
+=== Breeding ===
+
+The northern bald ibis breeds in loosely spaced colonies, nesting on cliff ledges or amongst boulders on steep slopes, usually on the coast or near a river. Volunteer climbers have created extra ledge spaces in the Souss-Massa colonies to ensure that breeding population is not limited by the availability of nest ledges, and artificial nest boxes are used in the managed colony at Birecik. In the past, the birds also nested in buildings.This ibis starts breeding at three to five years of age, and pairs for life. The male chooses a nest site, cleans it, and then advertises for a female by waving his crest and giving low rumbling calls. Once the birds have paired, the bond is reinforced through bowing displays and mutual preening. The nest is a loose construction of twigs lined with grass or straw. G. eremita normally lays two to four rough-surfaced eggs, which weigh an average of 50.16 g (1.769 oz), and are initially blue-white with brown spots, becoming brown during incubation. An egg in the collection of the British Museum was marked more thickly at the broad end, with "spots and very small blotches of yellowish brown and pale rufous". It was 0.93 in long and 0.68 in wide (2.37 × 1.73 cm). The clutch is incubated for 24–25 days to hatching, the chicks fledge in another 40–50 days, and the first flight takes place at about two months. Both parents incubate and feed the chicks.The northern bald ibis lives for an average of 20 to 25 years in captivity (oldest recorded male 37 years, oldest recorded female 30 years). The average age in the wild has been estimated as 10 to 15 years.
+
+
+=== Feeding ===
+
+This gregarious species commutes in flocks from the cliff breeding sites or winter roosts to its feeding areas, flying in a V formation. The flocks may contain up to 100 birds in winter. During the breeding season, the ibises regularly forage up to 15 km (9.3 mi) from the colony, and, although steppe not in current cultivation is preferred for feeding, they will also use fallow ground, and occasionally even actively cultivated fields.The northern bald ibis consumes a very wide variety of mainly animal food; faecal analysis of the Moroccan breeding population has shown that lizards and tenebrionid beetles predominate in the diet, although small mammals, ground-nesting birds, and invertebrates such as snails, scorpions, spiders, and caterpillars are also taken. Males will sometimes "scrounge" food from females. As the flock moves across the ground, the ibis uses its long bill to feel for food items in the loose, sandy soil. Since this bird hunts mainly by probing, a soft surface seems to be vital, and it is important that any vegetation is sparse, and not more than 15–20 cm (6–8 in) high.
+
+
+== Conservation status ==
+
+Although the northern bald ibis was long extinct in Europe, many colonies in Morocco and Algeria survived until the early 20th century, when they began to decline more rapidly, the last colony in Algeria disappearing in the late 1980s. In Morocco there were about 38 colonies in 1940 and 15 in 1975, but the last migratory populations in the Atlas Mountains had vanished by 1989. The species is endangered according to the IUCN scale, with an estimated population in 2018 of around 147 breeding pairs in the wild and over 1,000 in captivity. It was formerly considered critically endangered until heavy conservation action secured the breeding sites in Morocco and even allowed the birds to expand to other sites, as well as the semi-wild population conserved in Turkey as well as the reintroduction projects in Europe. The northern bald ibis is one of the key species to which the draft Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies, and it has a detailed, internationally agreed conservation action plan under the agreement. As a species that is threatened with extinction, it is listed on Appendix 1 of CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora), which means that commercial trade in the species (including parts and derivatives) is prohibited.The northern bald ibis has declined for several centuries, at least partly as a consequence of unidentified natural causes. The more rapid decline in the past hundred years, with a loss of 98% of the population between 1900 and 2002, is the result of a combination of factors. These include significant human persecution, especially hunting, and also the loss of steppe and non-intensive agricultural areas (particularly in Morocco), pesticide poisoning, disturbance, and dam construction. The discovery in Jordan of three dead adults from the Turkish colony seemed to confirm that the overuse of pesticides is still a cause of death on migration. These birds were tracked by satellite after leaving Birecik; they stopped off briefly at the Syrian colony, and were later found dead in the Jordanian desert. Although the cause of death was initially thought to have been from poison, probably laid by chicken farmers to kill rodents, the autopsy revealed that they had actually been
+electrocuted whilst standing on electricity pylons.
+
+
+=== Wild populations ===
+
+
+==== Morocco ====
+Monitoring of Moroccan wild population is guaranteed by BirdLife International partners, especially by RSPB, SEO/BirdLife and, recently GREPOM in cooperation with Souss-Massa National Park administration and the support of institutions like Prince Albert II of Monaco Foundation which is the Species Champion for Northern Bald Ibis. For the first time in the species' recorded history, there is now evidence of population growth in the wild, and the population in Morocco increased to 100 breeding pairs in the decade prior to 2008 and reached a record of 113 breeding pairs in 2013. Simple site and species protection has facilitated this growth. Quantitative assessments of the importance of sites for breeding, roosting, and foraging have guided actions to prevent disturbance and the loss of key areas to mass tourism development. Wardening by members of the local community has reduced human intrusion and increased the perceived value of the birds. The provision of drinking water and the removal and deterrence of predators and competitors enhances breeding prospects, and monitoring has confirmed that steppe and two-year fallows are key feeding habitats. 
+In early 2019 the total population in the two colonies of Souss-Massa National Park and Tamri reached 708 birds after 147 breeding pairs that laid eggs have produced 170 chicks in the last breeding season.Maintaining such non-intensive land uses in the future may present major management challenges, and the recovery in the Souss-Massa region remains precarious because the population is concentrated in just a few places. However, it could provide opportunities for natural extension of the range to formerly occupied sites further north in Morocco.
+
+The main cause of breeding failure at the Souss-Massa National Park is the loss of eggs to predators, especially the common raven which nest monitoring has shown to have had a serious impact at one sub-colony. The effects of predators on adult birds have not been studied, but the very similar southern bald ibis, Geronticus calvus, is hunted by large raptors, particularly those that share its breeding cliffs. There is evidence of chick starvation in some years, but the main threats to breeding birds are human disturbance and the loss of feeding habitat. There was a dramatic mortality incident at the Moroccan colonies in May 1996, when 40 adults died or disappeared over a period of nine days. Although analyses have not identified the cause, an obscure virus, a toxin, or botulism are thought to be the most likely causes of the deaths.
+
+
+==== Syria ====
+Conservation efforts for the Northern bald ibis in Syria began with the discovery of an unreported relict colony of this species in early 2002 in the Palmyra desert. The bald ibises still breeding in Syria, discovered during an extensive biodiversity survey carried out as part of a FAO cooperation project, are the last living descendants of those depicted in Egyptian hieroglyphs from 4500 years ago. The discovery was made possible through the use of traditional ecological knowledge of the Bedouin nomads.Following the discovery in Syria, a successful community-based ibis breeding intensive protection program was established in Palmyra during years 2002–2004, in parallel with an extensive capacity building program in the benefit of the local community and staff from the Syrian Steppe Commission. Fourteen chicks successfully fledged during this period.Beside protection and training operations, data on threats and on feeding and breeding ecology were collected in the field. An Ibis Protected Area was recommended and established, and an awareness and education program was also launched and successfully implemented.Two breeding failures were recorded in 2005 and 2008 following a change of project management and of ibis protection strategy, that occurred between 2004 and 2005. Three birds were tagged with satellite tags and the migratory route and wintering site of the colony were discovered in 2006. Three surveys were undertaken at the wintering site on the Ethiopian highlands between 2006 and 2009, establishing that no immediate threats were present at the site.Thanks to an IUCN project the Ibis Protected Area in Palmyra desert was further developed in 2008–2009, addressing the threats of infrastructure proliferation and oil company heavy prospection schemes.Meanwhile, it became apparent that only adults were reaching the wintering site in Ethiopia and that it was the low survival rate of immature birds - and thus an insufficient recruitment at the breeding colony in Palmyra - that was causing the slow and steady decline of the colony from 3 breeding pairs in 2002 to just 1 in 2010. Satellite tracking and surveys conducted in western Saudi Arabia during 2009–2010, with key cooperation of the Saudi Wildlife Authority, suggested that a combination of hunting and electrocution were causing a high mortality of dispersing immature ibises. This mortality is currently regarded as the main cause of the low recruitment occurred at the Palmyra colony during the years following the high breeding performance of period 2002-2004 (only 3 recruitment events out of 14 chicks fledged).A supplementation trial could be eventually conducted in 2010 by introducing captive-born chicks into the wild colony in Palmyra. For this aim, a first captive breeding center was established in Palmyra. Three chicks introduced at the wild colony in Palmyra followed a migrating wild adult for more than 1000 km from Palmyra well into southwest Saudi Arabia.The success of the trial, unique of its kind, reinvigorated the hopes that the colony could be still saved. Conservation efforts were interrupted in March 2011 due to the worsening of the political situation in Syria. Palmyra trained rangers have reportedly continued to protect the breeding birds even during the subsequent years. The last year a lone bird was seen returning to Palmyra is 2014 (it returned alone also in 2013). In 2015 no birds came back. As of 2017, some birds are still seen at the wintering grounds.
+
+
+==== Turkey ====
+With the loss of the genuinely wild Turkish population, the Ministry of Environment and Forestry's Directorate of Natural Preservation and National Parks established a new semi-wild colony at Birecik. This was heavily managed, with birds taken into captivity after the breeding season to prevent migration. The program was successful, with numbers at 205 as of March 2016. The intent is to allow the birds to migrate once the population reaches a stable 100 pairs, excluding young.The birds are released in late January or early February to breed outside the cages on ledges and, mainly, in the nest boxes in the breeding station compound. The ibises are free flying and forage around the Birecik area in forest nurseries, agricultural fields, and along the Euphrates, but supplementary food is also provided. Following the end of the breeding season, the birds are taken into cages in late July or early August to prevent migration. A trial migration using tagged birds confirmed the risks presented to travelling birds by pesticides. Later on the Syrian Civil War added one more reason to keep preventing migration.
+
+
+=== Reintroductions ===
+
+The guidelines for the conservation and reintroduction of the northern bald ibis were established in 2003 at an International Advisory Group for Northern Bald Ibis (IAGNBI) conference in Innsbruck at the Alpenzoo, which maintains the European studbook for the northern bald ibis.Decisions taken at the meeting included:
+There should be no augmenting of the wild populations at Souss-Massa or in Palmyra using zoo-bred ibises.
+There are two distinctive populations of northern bald ibis, and the separate ranges of the eastern and western forms should be respected.
+In order to prepare birds for release, groups of chicks should be hand-reared by human "parents".
+Migration routes and stop-over points will have to be taught to young birds, since it is unlikely that they will discover this information by themselves.A second conference in Spain in 2006 stressed the need to survey potential and former sites in north-west Africa and the Middle East for currently undetected colonies. The need to raise the standards of hygiene and husbandry in the Birecik aviaries was reiterated, and the prevalence of skin problems in a number of zoos reinforced the view that no zoo birds should be used for any free-flying trials. In future captive breeding and releasing programmes, only birds of known origin should be used.
+
+
+==== Zoo populations ====
+
+There are 850 northern bald ibises in European zoos and a further 250 in captivity in Japan and North America. The 49 European zoos keeping this species produce 80 to 100 young birds per year, and earlier attempts at releasing captive-bred birds included close to 150 birds between 1976 and 1986 from an aviary at Birecik, 75 from Tel Aviv Zoo in 1983, and an unspecified number from a project in Almería, Spain, from 1991 to 1994; all these attempts were unsuccessful. All northern bald ibises in zoos, other than those in Turkey, are of the western population, and were imported from Morocco. Three bloodlines exist; the earliest relates to importations to Zoo Basel, Switzerland in the 1950s and 1960s, the next is the descendants of birds taken in the 1970s to stock Rabat Zoo, and the last captured wild birds were those taken to the Naturzoo, Rheine, in 1976 and 1978. Captive birds have a high incidence of skin problems, and 40% of those birds that had to be put down suffered from chronic ulcerative dermatitis, characterised by feather loss, rawness, and ulceration on the back, neck, and the undersides of the wings. The cause of this disease is unknown. Other major disease problems reported in zoo collections have been avian tuberculosis, gastric foreign bodies, bone disease, and heart problems. An outbreak of West Nile virus in Bronx Park, New York, involved northern bald ibises amongst many other species of birds and mammals.
+
+
+==== Europe ====
+In 1504, a decree by Archbishop Leonhard of Salzburg made the northern bald ibis one of the world's earliest officially protected species. They nested in the cliffs and on castles and ruins in the Graz/Steiermark and Salzburg regions of Austria and vanished around 1630–1645. Young birds were hunted as a delicacy at feasts for the nobility. Despite the decree, it died out in Austria as elsewhere in Europe.
+
+There are now two ibis reintroduction projects in Austria, at Grünau and Kuchl.[1] A research station at Grünau has a breeding colony managed, like the Turkish population, as a free-flying flock which is caged at migration time. The aim here is to investigate flock interactions and hormonal status, behavioural and ecological aspects of natural foraging, and the establishment of traditions via social learning.The Scharnstein Project is an attempt to establish a migratory waldrapp colony by using ultralight planes to teach a migration route. The scheme builds on the Grünau research by developing a method to control and guide the autumn migration of a founder population, which then can pass this migration tradition to subsequent generations. In May 2002, 11 birds from the Vienna Zoo and the Grünau colony were trained to follow two microlight planes, and in 2003, a first attempt was made to lead a group of birds from Scharnstein to southern Tuscany. Due to adverse weather and technical problems, the birds had to be transported by road over a considerable part of the distance. The subsequent releases were more successful, with birds wintering in Tuscany, and, from 2005, returning to northern Austria. In 2008, a female ibis named Aurelia flew 930 km (580 mi) back to Austria for her fourth return to the breeding site. The hazards of the journey are shown by the loss of her two offspring and her mate while on the southern journey in the autumn of 2007.
+
+In August 2013 the European Union agreed to provide support to reintroduction projects until 2019 under its LIFE+ Biodiversity programme. The Reason for Hope project under the leadership of the biologist Dr. Johannes Fritz has operated one breeding and observation site in Austria, in Kuchl, near Salzburg, and two similar sites in Burghausen, Bavaria, and in Überlingen on Lake Constance in Baden-Württemberg. The positions and flight patterns of migratory birds are monitored with light-weight solar transmitters. After learning to follow their human foster-mothers seated in ultralight aircraft, around 30 young birds are led over the Alps to spend the winter months in Tuscany. Numerous studies on migratory bird behaviour have been published and presentations given at symposiums.  In November 2019 it was announced that the project team succeeded in uniting juvenile birds with experienced adult birds so that they could fly to their wintering site together.Proyecto Eremita is a Spanish reintroduction involving the release of nearly 30 birds in the Ministry of Defence training ground in La Janda district, Barbate, Cádiz Province. It had its first success in 2008, when a pair laid two eggs. This is probably the first attempt to breed in the wild in Spain for 500 years as the last definite reference to the northern bald ibis breeding in Spain is from a 15th-century falconry book. This effort has been undertaken by the Andalusian government's Environmental Ministry, the Spanish Ministry of Defence, and the Zoobotánico de Jeréz (Jerez Zoo and Botanical Gardens), with the assistance of the Doñana Biological Station, CSIC and volunteers from the Cádiz Natural History Society. Previously, two birds left the area in 2005 and 14 in 2006, but nothing is known of their whereabouts other than that a ringed bird from Spain was seen in the Middle Atlas, Morocco in 2005. Internet pictures of this species taken near Armação de Pêra, Algarve, Portugal in 2009 and later, may be related to those releases in Spain. In the interim, the Spanish colony has been growing very well, from 9 breeding pairs in 2011, 10 in 2012 and 15 in 2013 to 23 breeding pairs in 2014, which successfully raised 25 chicks in 2014 (Quercus 349(2015): 14-23). In 2014 the total population of this colony was 78 wild birds split into two colonies, originally along the cliffs of the Atlantic coast and in 2012 with a second colony of 5–6 breeding pairs that started at the cliffs 10 km inland next to a country road at La Barca de Vejer (Vejer de la Frontera).
+
+
+==== Northern Morocco ====
+
+There is a planned reintroduction of the ibis at Ain Tijja-Mezguitem in the north-east of Morocco. Since the wild populations further south remain vulnerable, and the porous sandstone of their breeding ledges is exposed to erosion, the intention is to establish a non-migratory population (stocked from German, Swiss, and Austrian zoos) in an area where this species was known to have bred up to about 1980. The station in the Rif mountains was built in 2000, and stocked with the first group of zoo-bred birds. A second importation of zoo-bred birds and the construction of an information centre took place in 2004. Six pairs bred in 2006 subsequent to a change in the birds' diet, and six offspring from five nests were successfully reared. In 2007 there were 19 birds (13 adults and six juveniles) in the aviary.The rock walls of the mountains have many potential breeding ledges, and an artificial lake provides water to the birds and to the local human population. Steppe pasture which is not exposed to herbicides or pesticides gives good foraging. Once the population reaches around 40 birds, a release will be initiated, subject to international agreement. The reintroduction site is 760 km (470 mi) from Agadir on the other side of the Atlas Mountains, so accidental contamination of the wild colonies is unlikely.
+
+
+== In culture ==
+
+According to local legend in the Birecik area, the northern bald ibis was one of the first birds that Noah released from the Ark as a symbol of fertility, and a lingering religious sentiment in Turkey helped the colonies there to survive long after the demise of the species in Europe, as described above.This ibis was revered as a holy bird and a symbol of brilliance and splendour in Ancient Egypt, where, together with the sacred ibis, it was regarded as an embodiment of Thoth, scribe of the gods, who was usually depicted with a man's body and the head of an ibis. The Old Egyptian word akh, "to be resplendent, to shine", was denoted in hieroglyphs by a bald ibis, presumably as a reference to its glossy plumage. In a more abstract sense, akh stood for excellence, glory, honour, and virtue. It has also been used to signify the soul or spirit, one of five elements constituting personality.Herodotus wrote of the man-eating Stymphalian birds, which had wings of brass and sharp metallic feathers they could fire at their victims. Ridding Lake Stymphalia in Arcadia of these creatures was one of the twelve labours of Heracles. These mythical birds are sometimes considered to be based on the northern bald ibis, but since they were described as marsh birds, and usually depicted without crests, the legendary species is more likely to be derived from the sacred ibis. Some depictions, such as the 6th-century BC Athenian black-figure amphora in the British Museum, clearly show the black head and white body of the sacred ibis. After the bald ibis became extinct in Central Europe, some later writers thought that Gesner's description was one of several in his book depicting mythical creatures.
+
+The bird painted in 1490 in one of the Gothic frescoes in the Holy Trinity Church in Hrastovlje (now southwestern Slovenia) in the Karst by John of Kastav was most probably the northern bald ibis. A small illustration of the northern bald ibis is found in the illuminated St Galler Handschrift of 1562, a drawing by Joris Hoefnagel in Missale Romanum (1582-1590) and in paintings in the collection of Rudolf II at Vienna. It is believed that it had also been depicted at other places in Istria and Dalmatia, where it was presumably native during the Middle Ages, e.g. in the local church in Gradišče pri Divači and in the coat of arms of the noble family Elio from Koper. The portal of Lukovec Castle in Lukovica pri Brezovici (central Slovenia) also features this species.In Birecik, Turkey an ancient celebration 'Kelaynak yortusu' held in mid-February to mark the return of the birds from Africa was revived in the 1950s.Several countries have produced postage stamps which depict the northern bald ibis. They include Algeria, Morocco, Sudan, Syria, Turkey, and Yemen, which are breeding or migration locations; Austria, which is seeking to reintroduce the bird; and Jersey, which has a small captive population.

+The Angolan giraffe (Giraffa camelopardalis angolensis or Giraffa giraffa angolensis), also known as the Namibian giraffe, is a subspecies of giraffe that is found in northern Namibia, south-western Zambia, Botswana, and western Zimbabwe.
+
+
+== Taxonomy ==
+A 2009 genetic study on this subspecies suggests the northern Namib Desert and Etosha National Park populations each form a separate subspecies. However, genetic studies based on mitochondrial DNA do not support the division into two subspecies., but could identify giraffes in southern Zimbabwe as the Angolan giraffe, suggesting a further eastward distribution than expected.
+
+
+== Description ==
+This subspecies has large brown blotches with edges that are either somewhat notched or have angular extensions. The spotting pattern extends throughout the legs but not the upper part of the face. The neck and rump patches tend to be fairly small. The subspecies also has a white ear patch. 
+
+
+== Habitat ==
+Home range size of Angolan giraffes was found to be larger in unproductive areas such as the Namib Desert and much smaller in more productive areas such as Lake Manyara National Park. However, that home range size could be affected by abiotic(e.g climate), biotic(e.g forage availability, predator densities) and human influence(e.g population growth)
+
+
+== Seasonal movement ==
+As far as seasonal movements of giraffes were concerned, they were not as distinctive as those in other giraffe populations around the world. Male Giraffe  moves longer than Female giraffe and also it has longer average daily movement (5.64km compared to 1.87km in 180 days during hot-dry season).

+The northern giraffe (Giraffa camelopardalis), also known as three-horned giraffe, is the type species of giraffe, G. camelopardalis, and is native to North Africa, although alternative taxonomic hypotheses have proposed the northern giraffe as a separate species.Once abundant throughout Africa since the 19th century, Northern giraffes ranged from Senegal, Mali and Nigeria from West Africa to up north in Egypt.  The similar West African giraffes lived in Algeria and Morocco in ancient periods until their extinctions due to the Saharan dry climate.Giraffes collectively are considered Vulnerable to extinction by the International Union for Conservation of Nature (IUCN), with around 97,000 wild individuals alive in 2016,  of which 5,195 are Northern giraffes.
+
+
+== Taxonomy and evolution ==
+The current IUCN taxonomic scheme lists one species of giraffe with the name G. camelopardalis and nine subspecies. A 2021 whole genome sequencing study suggests the northern giraffe as a separate species, and postulates the existence of three distinct subspecies.
+
+
+== Description ==
+
+Often mistaken with the Southern Giraffes, Northern giraffes can be differentiated by the shape and size of the two distinctive horn-like protuberances known as ossicones on their foreheads; they are longer and larger than those of southern giraffes. Bull Northern giraffes have a third cylindrical ossicone in the center of the head just above the eyes, which is from 3 to 5 inches long.
+
+
+== Distribution and habitat ==
+Northern giraffes live in savannahs, shrublands, and woodlands. After numerous local extinctions, Northern giraffes are the least numerous giraffe species, and the most endangered. In East Africa, they are mostly found in Kenya and southwestern Ethiopia, and rarely in northeastern Democratic Republic of the Congo and South Sudan. In Central Africa, there are about 2,000 in the Central African Republic, Chad and Cameroon. Once widespread in West Africa, a few hundred Northern giraffes are confined in the Dosso Reserve of Kouré, Niger. They are isolated in South Sudan, Kenya, Chad and Niger. They commonly live both in and outside of protected areas.The earliest ranges of the Northern giraffes were in Chad during the late Pliocene. Once abundant in North Africa, they lived in Algeria from the early Pleistocene during the Quaternary period. They lived in Morocco, Libya and Egypt until their extinction there around AD 600, as the drying climate of the Sahara made conditions impossible for giraffes. Giraffe bones and fossils have been found across these countries.

+Gorillas are herbivorous,  predominantly ground-dwelling great apes that inhabit the tropical forests of equatorial Africa. The genus Gorilla is divided into two species: the eastern gorilla and the western gorilla, and either four or five subspecies. The DNA of gorillas is highly similar to that of humans, from 95 to 99% depending on what is included, and they are the next closest living relatives to humans after chimpanzees and bonobos.
+Gorillas are the largest living primates, reaching heights between 1.25 and 1.8 metres, weights between 100 and 270 kg, and arm spans up to 2.6 metres, depending on species and sex. They tend to live in troops, with the leader being called a silverback. The Eastern gorilla is distinguished from the Western by darker fur colour and some other minor morphological differences. Gorillas tend to live 35–40 years in the wild. The oldest gorilla known is Fatou (b. 1957), who is still alive at the advanced age of 65 years.
+Gorillas' natural habitats cover tropical or subtropical forest in Sub-Saharan Africa. Although their range covers a small percentage of Sub-Saharan Africa, gorillas cover a wide range of elevations. The mountain gorilla inhabits the Albertine Rift montane cloud forests of the Virunga Volcanoes, ranging in altitude from 2,200 to 4,300 metres (7,200 to 14,100 ft). Lowland gorillas live in dense forests and lowland swamps and marshes as low as sea level, with western lowland gorillas living in Central West African countries and eastern lowland gorillas living in the Democratic Republic of the Congo near its border with Rwanda.
+There are thought to be around 316,000 western gorillas in the wild, and 5,000 eastern gorillas. Both species are classified as Critically Endangered by the IUCN; all subspecies are classified as Critically Endangered with the exception of the mountain gorilla, which is classified as Endangered. There are many threats to their survival, such as poaching, habitat destruction, and disease, which threaten the survival of the species. However, conservation efforts have been successful in some areas where they live.
+
+
+== Etymology ==
+
+The word "gorilla" comes from the history of Hanno the Navigator (c.  500 BC), a Carthaginian explorer on an expedition to the west African coast to the area that later became Sierra Leone. Members of the expedition encountered "savage people, the greater part of whom were women, whose bodies were hairy, and whom our interpreters called Gorillae". It is unknown whether what the explorers encountered were what we now call gorillas, another species of ape or monkeys, or humans. Skins of gorillai women, brought back by Hanno, are reputed to have been kept at Carthage until Rome destroyed the city 350 years later at the end of the Punic Wars, 146 BC.
+The American physician and missionary Thomas Staughton Savage and naturalist Jeffries Wyman first described the western gorilla in 1847 from specimens obtained in Liberia. They called it Troglodytes gorilla, using the then-current name of the chimpanzee genus.  The species name was derived from Ancient Greek  Γόριλλαι (gorillai)  'tribe of hairy women', as described by Hanno.
+
+
+== Evolution and classification ==
+The closest relatives of gorillas are the other two Homininae genera, chimpanzees and humans, all of them having diverged from a common ancestor about 7 million years ago. Human gene sequences differ only 1.6% on average from the sequences of corresponding gorilla genes, but there is further difference in how many copies each gene has. Until recently, gorillas were considered to be a single species, with three subspecies: the western lowland gorilla, the eastern lowland gorilla and the mountain gorilla. There is now agreement that there are two species, each with two subspecies. More recently, a third subspecies has been claimed to exist in one of the species. The separate species and subspecies developed from a single type of gorilla during the Ice Age, when their forest habitats shrank and became isolated from each other.Primatologists continue to explore the relationships between various gorilla populations. The species and subspecies listed here are the ones upon which most scientists agree.
+The proposed third subspecies of Gorilla beringei, which has not yet received a trinomen, is the Bwindi population of the mountain gorilla, sometimes called the Bwindi gorilla.
+Some variations that distinguish the classifications of gorilla include varying density, size, hair colour, length, culture, and facial widths. Population genetics of the lowland gorillas suggest that the western and eastern lowland populations diverged around 261 thousand years ago.
+
+
+== Characteristics ==
+
+Wild male gorillas weigh 136 to 227 kg (300 to 500 lb), while adult females weigh 68–113 kg (150–250 lb). Adult males are 1.4 to 1.8 m (4 ft 7 in to 5 ft 11 in) tall, with an arm span that stretches from 2.3 to 2.6 m (7 ft 7 in to 8 ft 6 in). Female gorillas are shorter at 1.25 to 1.5 m (4 ft 1 in to 4 ft 11 in), with smaller arm spans. Colin Groves (1970) calculated the average weight of 42 wild adult male gorillas at 144 kg, while Smith and Jungers (1997) found the average weight of 19 wild adult male gorillas to be 169 kg. Adult male gorillas are known as silverbacks due to the characteristic silver hair on their backs reaching to the hips. The tallest gorilla recorded was a 1.95 m (6 ft 5 in) silverback with an arm span of 2.7 m (8 ft 10 in), a chest of 1.98 m (6 ft 6 in), and a weight of 219 kg (483 lb), shot in Alimbongo, northern Kivu in May 1938. The heaviest gorilla recorded was a 1.83 m (6 ft 0 in) silverback shot in Ambam, Cameroon, which weighed 267 kg (589 lb). Males in captivity can be overweight and reach weights up to 310 kg (683 lb).
+
+The eastern gorilla is more darkly coloured than the western gorilla, with the mountain gorilla being the darkest of all. The mountain gorilla also has the thickest hair. The western lowland gorilla can be brown or greyish with a reddish forehead. In addition, gorillas that live in lowland forest are more slender and agile than the more bulky mountain gorillas. The eastern gorilla also has a longer face and broader chest than the western gorilla. Like humans, gorillas have individual fingerprints.
+Their eye colour is dark brown, framed by a black ring around the iris. Gorilla facial structure is described as mandibular prognathism, that is, the mandible protrudes farther out than the maxilla. Adult males also have a prominent sagittal crest.
+Gorillas move around by knuckle-walking, although they sometimes walk upright for short distances, typically while carrying food or in defensive situations. A 2018 study investigating the hand posture of 77 mountain gorillas at Bwindi Impenetrable National Park (8% of the population) found that knuckle walking was done only 60% of the time, and they also supported their weight on their fists, the backs of their hands/feet, and on their palms/soles (with the digits flexed). Such a range of hand postures was previously thought to have been used by only orangutans. Studies of gorilla handedness have yielded varying results, with some arguing for no preference for either hand, and others right-hand dominance for the general population.Studies have shown gorilla blood is not reactive to anti-A and anti-B monoclonal antibodies, which would, in humans, indicate type O blood. Due to novel sequences, though, it is different enough to not conform with the human ABO blood group system, into which the other great apes fit.A gorilla's lifespan is normally between 35 and 40 years, although zoo gorillas may live for 50 years or more. Colo, a female western gorilla at the Columbus Zoo and Aquarium, was the oldest known gorilla at 60 years of age when she died on 17 January 2017. Ozzie was 61 years old at the time of his death in January 2022.
+
+
+== Distribution and habitat ==
+
+Gorillas have a patchy distribution. The range of the two species is separated by the Congo River and its tributaries. The western gorilla lives in west central Africa, while the eastern gorilla lives in east central Africa. Between the species, and even within the species, gorillas live in a variety of habitats and elevations. Gorilla habitat ranges from montane forest to swampland. Eastern gorillas inhabit montane and submontane forests between 650 and 4,000 m (2,130 and 13,120 ft) above sea level.Mountain gorillas live in montane forests at the higher end of the elevation range, while eastern lowland gorillas live in submontane forests at the lower end. In addition, eastern lowland gorillas live in montane bamboo forests, as well as lowland forests ranging from 600–3,308 m (1,969–10,853 ft) in elevation. Western gorillas live in both lowland swamp forests and montane forests, at elevations ranging from sea level to 1,600 m (5,200 ft). Western lowland gorillas live in swamp and lowland forests ranging up to 1,600 m (5,200 ft), and Cross River gorillas live in low-lying and submontane forests ranging from 150–1,600 m (490–5,250 ft).
+
+
+== Ecology ==
+
+
+=== Diet and foraging ===
+
+A gorilla's day is divided between rest periods and travel or feeding periods. Diets differ between and within species. Mountain gorillas mostly eat foliage, such as leaves, stems, pith, and shoots, while fruit makes up a very small part of their diets. Mountain gorilla food is widely distributed and neither individuals nor groups have to compete with one another. Their home ranges vary from 3 to 15 km2 (1.2 to 5.8 sq mi), and their movements range around 500 m (0.31 mi) or less on an average day. Despite eating a few species in each habitat, mountain gorillas have flexible diets and can live in a variety of habitats.
+
+Eastern lowland gorillas have more diverse diets, which vary seasonally. Leaves and pith are commonly eaten, but fruits can make up as much as 25% of their diets. Since fruit is less available, lowland gorillas must travel farther each day, and their home ranges vary from 2.7 to 6.5 km2 (1.0 to 2.5 sq mi), with day ranges 154–2,280 m (0.096–1.417 mi). Eastern lowland gorillas will also eat insects, preferably ants. Western lowland gorillas depend on fruits more than the others and they are more dispersed across their range. They travel even farther than the other gorilla subspecies, at 1,105 m (0.687 mi) per day on average, and have larger home ranges of 7–14 km2 (2.7–5.4 sq mi). Western lowland gorillas have less access to terrestrial herbs, although they can access aquatic herbs in some areas. Termites and ants are also eaten.
+Gorillas rarely drink water "because they consume succulent vegetation that is comprised of almost half water as well as morning dew", although both mountain and lowland gorillas have been observed drinking.
+
+
+=== Nesting ===
+
+Gorillas construct nests for daytime and night use. Nests tend to be simple aggregations of branches and leaves about 2 to 5 ft (0.61 to 1.52 m) in diameter and are constructed by individuals. Gorillas, unlike chimpanzees or orangutans, tend to sleep in nests on the ground. The young nest with their mothers, but construct nests after three years of age, initially close to those of their mothers. Gorilla nests are distributed arbitrarily and use of tree species for site and construction appears to be opportunistic. Nest-building by great apes is now considered to be not just animal architecture, but as an important instance of tool use.Gorillas make a new nest to sleep on daily and do not use the previous one. This even if remaining in the same place. Usually, they are made an hour before dusk, to be ready to sleep when night falls. Gorillas sleep longer than humans, an average of 12 hours per day.
+
+
+=== Threats and competition ===
+One possible predator of gorillas is the leopard. Gorilla remains have been found in leopard scat, but this may be the result of scavenging. When the group is attacked by humans, leopards, or other gorillas, an individual silverback will protect the group, even at the cost of his own life. Gorillas do not appear to directly compete with chimpanzees in areas where they overlap. When fruit is abundant gorilla and chimpanzee diets converge, but when fruit is scarce gorillas resort to vegetation. The two apes may also feed on different species, whether fruit or insects. Gorillas and chimpanzees usually ignore or avoid each other when feeding on the same tree, but coalitions of chimpanzees have been observed attacking families of gorillas including silverbacks and killing infants.
+
+
+== Behaviour ==
+
+
+=== Social structure ===
+
+Gorillas live in groups called troops. Troops tend to be made of one adult male or silverback, with a harem of multiple adult females and their offspring. However, multiple-male troops also exist. A silverback is typically more than 12 years of age, and is named for the distinctive patch of silver hair on his back, which comes with maturity. Silverbacks have large canine teeth that also come with maturity. Both males and females tend to emigrate from their natal groups. For mountain gorillas, females disperse from their natal troops more than males. Mountain gorillas and western lowland gorillas also commonly transfer to second new groups.Mature males also tend to leave their groups and establish their own troops by attracting emigrating females. However, male mountain gorillas sometimes stay in their natal troops and become subordinate to the silverback. If the silverback dies, these males may be able to become dominant or mate with the females. This behaviour has not been observed in eastern lowland gorillas. In a single male group, when the silverback dies, the females and their offspring disperse and find a new troop. Without a silverback to protect them, the infants will likely fall victim to infanticide. Joining a new group is likely to be a tactic against this. However, while gorilla troops usually disband after the silverback dies, female eastern lowlands gorillas and their offspring have been recorded staying together until a new silverback transfers into the group. This likely serves as protection from leopards.
+
+The silverback is the centre of the troop's attention, making all the decisions, mediating conflicts, determining the movements of the group, leading the others to feeding sites, and taking responsibility for the safety and well-being of the troop. Younger males subordinate to the silverback, known as blackbacks, may serve as backup protection. Blackbacks are aged between 8 and 12 years and lack the silver back hair. The bond that a silverback has with his females forms the core of gorilla social life. Bonds between them are maintained by grooming and staying close together. Females form strong relationships with males to gain mating opportunities and protection from predators and infanticidal outside males. However, aggressive behaviours between males and females do occur, but rarely lead to serious injury. Relationships between females may vary. Maternally related females in a troop tend to be friendly towards each other and associate closely. Otherwise, females have few friendly encounters and commonly act aggressively towards each other.Females may fight for social access to males and a male may intervene. Male gorillas have weak social bonds, particularly in multiple-male groups with apparent dominance hierarchies and strong competition for mates. Males in all-male groups, though, tend to have friendly interactions and socialise through play, grooming, and staying together, and occasionally they even engage in homosexual interactions. Severe aggression is rare in stable groups, but when two mountain gorilla groups meet the two silverbacks can sometimes engage in a fight to the death, using their canines to cause deep, gaping injuries.
+
+
+=== Reproduction and parenting ===
+
+Females mature at 10–12 years (earlier in captivity), and males at 11–13 years. A female's first ovulatory cycle occurs when she is six years of age, and is followed by a two-year period of adolescent infertility. The estrous cycle lasts 30–33 days, with outward ovulation signs subtle compared to those of chimpanzees. The gestation period lasts 8.5 months. Female mountain gorillas first give birth at 10 years of age and have four-year interbirth intervals. Males can be fertile before reaching adulthood. Gorillas mate year round.Females will purse their lips and slowly approach a male while making eye contact. This serves to urge the male to mount her. If the male does not respond, then she will try to attract his attention by reaching towards him or slapping the ground. In multiple-male groups, solicitation indicates female preference, but females can be forced to mate with multiple males. Males incite copulation by approaching a female and displaying at her or touching her and giving a "train grunt". Recently, gorillas have been observed engaging in face-to-face sex, a trait once considered unique to humans and bonobos.
+
+Gorilla infants are vulnerable and dependent, thus mothers, their primary caregivers, are important to their survival. Male gorillas are not active in caring for the young, but they do play a role in socialising them to other youngsters. The silverback has a largely supportive relationship with the infants in his troop and shields them from aggression within the group. Infants remain in contact with their mothers for the first five months and mothers stay near the silverback for protection. Infants suckle at least once per hour and sleep with their mothers in the same nest.Infants begin to break contact with their mothers after five months, but only for a brief period each time. By 12 months old, infants move up to five m (16 ft) from their mothers. At around 18–21 months, the distance between mother and offspring increases and they regularly spend time away from each other. In addition, nursing decreases to once every two hours. Infants spend only half of their time with their mothers by 30 months. They enter their juvenile period at their third year, and this lasts until their sixth year. At this time, gorillas are weaned and they sleep in a separate nest from their mothers. After their offspring are weaned, females begin to ovulate and soon become pregnant again. The presence of play partners, including the silverback, minimizes conflicts in weaning between mother and offspring.
+
+
+=== Communication ===
+
+Twenty-five distinct vocalisations are recognised, many of which are used primarily for group communication within dense vegetation. Sounds classified as grunts and barks are heard most frequently while traveling, and indicate the whereabouts of individual group members. They may also be used during social interactions when discipline is required. Screams and roars signal alarm or warning, and are produced most often by silverbacks. Deep, rumbling belches suggest contentment and are heard frequently during feeding and resting periods. They are the most common form of intragroup communication.For this reason, conflicts are most often resolved by displays and other threat behaviours that are intended to intimidate without becoming physical. As a result, fights do not occur very frequently. The ritualized charge display is unique to gorillas. The entire sequence has nine steps: (1) progressively quickening hooting, (2) symbolic feeding, (3) rising bipedally, (4) throwing vegetation, (5) chest-beating with cupped hands, (6) one leg kick, (7) sideways running, two-legged to four-legged, (8) slapping and tearing vegetation, and (9) thumping the ground with palms to end display.A gorilla's chest-beat may vary in frequency depending on its size. Smaller ones tend to have higher frequencies, while larger ones tend to be lower. They also do it the most when females are ready to mate.
+
+
+== Intelligence ==
+
+Gorillas are considered highly intelligent. A few individuals in captivity, such as Koko, have been taught a subset of sign language. Like the other great apes, gorillas can laugh, grieve, have "rich emotional lives", develop strong family bonds, make and use tools, and think about the past and future. Some researchers believe gorillas have spiritual feelings or religious sentiments. They have been shown to have cultures in different areas revolving around different methods of food preparation, and will show individual colour preferences.
+
+
+=== Tool use ===
+
+The following observations were made by a team led by Thomas Breuer of the Wildlife Conservation Society in September 2005. Gorillas are now known to use tools in the wild. A female gorilla in the Nouabalé-Ndoki National Park in the Republic of Congo was recorded using a stick as if to gauge the depth of water whilst crossing a swamp. A second female was seen using a tree stump as a bridge and also as a support whilst fishing in the swamp. This means all of the great apes are now known to use tools.In September 2005, a two-and-a-half-year-old gorilla in the Republic of Congo was discovered using rocks to smash open palm nuts inside a game sanctuary. While this was the first such observation for a gorilla, over 40 years previously, chimpanzees had been seen using tools in the wild 'fishing' for termites. Nonhuman great apes are endowed with semiprecision grips, and have been able to use both simple tools and even weapons, such as improvising a club from a convenient fallen branch.
+
+
+== Scientific study ==
+American physician and missionary Thomas Staughton Savage obtained the first specimens (the skull and other bones) during his time in Liberia. The first scientific description of gorillas dates back to an article by Savage and the naturalist Jeffries Wyman in 1847 in Proceedings of the Boston Society of Natural History, where Troglodytes gorilla is described, now known as the western gorilla. Other species of gorilla were described in the next few years.
+
+The explorer Paul Du Chaillu was the first westerner to see a live gorilla during his travel through western equatorial Africa from 1856 to 1859. He brought dead specimens to the UK in 1861.The first systematic study was not conducted until the 1920s, when Carl Akeley of the American Museum of Natural History traveled to Africa to hunt for an animal to be shot and stuffed. On his first trip, he was accompanied by his friends Mary Bradley, a mystery writer, her husband, and their young daughter Alice, who would later write science fiction under the pseudonym James Tiptree Jr. After their trip, Mary Bradley wrote On the Gorilla Trail. She later became an advocate for the conservation of gorillas, and wrote several more books (mainly for children). In the late 1920s and early 1930s, Robert Yerkes and his wife Ava helped further the study of gorillas when they sent Harold Bigham to Africa. Yerkes also wrote a book in 1929 about the great apes.
+After World War II, George Schaller was one of the first researchers to go into the field and study primates. In 1959, he conducted a systematic study of the mountain gorilla in the wild and published his work. Years later, at the behest of Louis Leakey and the National Geographic, Dian Fossey conducted a much longer and more comprehensive study of the mountain gorilla. When she published her work, many misconceptions and myths about gorillas were finally disproved, including the myth that gorillas are violent.
+Western lowland gorillas (G. g. gorilla) are believed to be one of the zoonotic origins of HIV/AIDS. The SIVgor Simian immunodeficiency virus that infects them is similar to a certain strain of HIV-1.
+
+
+=== Genome sequencing ===
+The gorilla became the next-to-last great ape genus to have its genome sequenced. The first gorilla genome was generated with short read and Sanger sequencing using DNA from a female western lowland gorilla named Kamilah. This gave scientists further insight into the evolution and origin of humans. Despite the chimpanzees being the closest extant relatives of humans, 15% of the human genome was found to be more like that of the gorilla. In addition, 30% of the gorilla genome "is closer to human or chimpanzee than the latter are to each other; this is rarer around coding genes, indicating pervasive selection throughout great ape evolution, and has functional consequences in gene expression." Analysis of the gorilla genome has cast doubt on the idea that the rapid evolution of hearing genes gave rise to language in humans, as it also occurred in gorillas.
+
+
+== Captivity ==
+
+Gorillas became highly prized by western zoos since the 19th century, though the earliest attempts to keep them in captive facilities ended in their early death. In the late 1920s the care of captive gorillas significantly improved. Colo (December 22, 1956 – January 17, 2017) of the Columbus Zoo and Aquarium was the first gorilla to be born in captivity.Captive gorillas exhibit stereotypic behaviors, including eating disorders — such as regurgitation, reingestion and coprophagy — self-injurious or conspecific aggression, pacing, rocking, sucking of fingers or lip smacking, and overgrooming. Negative vigilance of visitor behaviors have been identified as starting, posturing and charging at visitors. Groups of bachelor gorillas containing young silverbacks have significantly higher levels of aggression and wounding rates than mixed age and sex groups.The use of both internal and external privacy screens on exhibit windows has been shown to alleviate stresses from visual effects of high crowd densities, leading to decreased stereotypic behaviors in the gorillas. Playing naturalistic auditory stimuli as opposed to classical music, rock music, or no auditory enrichment (which allows for crowd noise, machinery, etc. to be heard) has been noted to reduce stress behavior as well. Enrichment modifications to feed and foraging, where clover-hay is added to an exhibit floor, decrease stereotypic activities while simultaneously increasing positive food-related behaviors.Recent research on captive gorilla welfare emphasizes a need to shift to individual assessments instead of a one-size-fits-all group approach to understanding how welfare increases or decreases based on a variety of factors. Individual characteristics such as age, sex, personality and individual histories are essential in understanding that stressors will affect each individual gorilla and their welfare differently.
+
+
+== Conservation status ==
+
+All species (and subspecies) of gorilla are listed as endangered or critically endangered on the IUCN Red List. All gorillas are listed in Appendix I of the Convention on International Trade in Endangered Species (CITES), meaning that international export/import of the species, including in parts and derivatives, is regulated. Around 316,000 western lowland gorillas are thought to exist in the wild, 4,000 in zoos, thanks to conservation; eastern lowland gorillas have a population of under 5,000 in the wild and 24 in zoos. Mountain gorillas are the most severely endangered, with an estimated population of about 880 left in the wild and none in zoos. Threats to gorilla survival include habitat destruction and poaching for the bushmeat trade. Gorillas are closely related to humans, and are susceptible to diseases that humans also get infected by. In 2004, a population of several hundred gorillas in the Odzala National Park, Republic of Congo was essentially wiped out by the Ebola virus. A 2006 study published in Science concluded more than 5,000 gorillas may have died in recent outbreaks of the Ebola virus in central Africa. The researchers indicated in conjunction with commercial hunting of these apes, the virus creates "a recipe for rapid ecological extinction". In captivity, its also been observed that gorillas can also be infected with COVID-19.Conservation efforts include the Great Apes Survival Project, a partnership between the United Nations Environment Programme and the UNESCO, and also an international treaty, the Agreement on the Conservation of Gorillas and Their Habitats, concluded under UNEP-administered Convention on Migratory Species. The Gorilla Agreement is the first legally binding instrument exclusively targeting gorilla conservation; it came into effect on 1 June 2008. Governments of countries where gorillas live placed a ban on their killing and trading, but weak law enforcement still poses a threat to them, since the governments rarely apprehend poachers, traders and consumers that rely on gorillas for profit.
+
+
+== Cultural significance ==
+
+In Cameroon's Lebialem highlands, folk stories connect people and gorillas via totems; a gorilla's death means the connected person will die also. This creates a local conservation ethic. Many different indigenous peoples interact with wild gorillas. Some have detailed knowledge; the Baka have words to distinguish at least ten types of gorilla individuals, by sex, age, and relationships. In 1861, alongside tales of hunting enormous gorillas, the traveller and anthropologist Paul Du Chaillu reported the Cameroonian story that a pregnant woman who sees a gorilla will give birth to one.In 1911, the anthropologist Albert Jenks noted the Bulu people's knowledge of gorilla behaviour and ecology, and their gorilla stories. In one such story, "The Gorilla and the Child", a gorilla speaks to people, seeking help and trust, and stealing a baby; a man accidentally kills the baby while attacking the gorilla. Even far from where gorillas live, savannah tribes pursue "cult-like worship" of the apes. Some beliefs are widespread among indigenous peoples. The Fang name for gorilla is ngi while the Bulu name is njamong; the root ngi means fire, denoting a positive energy. From the Central African Republic to Cameroon and Gabon, stories of reincarnations as gorillas, totems, and transformations similar to those recorded by Du Chaillu are still told in the 21st century.Since gaining international attention, gorillas have been a recurring element of many aspects of popular culture and media. They were usually portrayed as murderous and aggressive. Inspired by Emmanuel Frémiet's Gorilla Carrying off a Woman, gorillas have been depicted kidnapping human women. This theme was used in films such as Ingagi (1930) and most notably King Kong (1933). The comedic play The Gorilla, which debuted in 1925, featured an escaped gorilla taking a woman from her house. Several films would use the "escaped gorilla" trope including The Strange Case of Doctor Rx (1942), The Gorilla Man (1943), Gorilla at Large (1954) and the Disney cartoons The Gorilla Mystery (1930) and Donald Duck and the Gorilla (1944).Gorillas have been used as opponents to jungle-themed heroes such as Tarzan and Sheena, Queen of the Jungle, as well as superheroes. The DC comics supervillain Gorilla Grodd is an enemy of the Flash. Gorillas also serve as antagonists in the 1968 film Planet of the Apes. More positive and sympathetic portrayals of gorillas include the films Son of Kong (1933), Mighty Joe Young (1949), Gorillas in the Mist (1988) and Instinct (1999) and the 1992 novel Ishmael. Gorillas have been featured in video games as well, notably Donkey Kong.

+Gorillas are herbivorous,  predominantly ground-dwelling great apes that inhabit the tropical forests of equatorial Africa. The genus Gorilla is divided into two species: the eastern gorilla and the western gorilla, and either four or five subspecies. The DNA of gorillas is highly similar to that of humans, from 95 to 99% depending on what is included, and they are the next closest living relatives to humans after chimpanzees and bonobos.
+Gorillas are the largest living primates, reaching heights between 1.25 and 1.8 metres, weights between 100 and 270 kg, and arm spans up to 2.6 metres, depending on species and sex. They tend to live in troops, with the leader being called a silverback. The Eastern gorilla is distinguished from the Western by darker fur colour and some other minor morphological differences. Gorillas tend to live 35–40 years in the wild. The oldest gorilla known is Fatou (b. 1957), who is still alive at the advanced age of 65 years.
+Gorillas' natural habitats cover tropical or subtropical forest in Sub-Saharan Africa. Although their range covers a small percentage of Sub-Saharan Africa, gorillas cover a wide range of elevations. The mountain gorilla inhabits the Albertine Rift montane cloud forests of the Virunga Volcanoes, ranging in altitude from 2,200 to 4,300 metres (7,200 to 14,100 ft). Lowland gorillas live in dense forests and lowland swamps and marshes as low as sea level, with western lowland gorillas living in Central West African countries and eastern lowland gorillas living in the Democratic Republic of the Congo near its border with Rwanda.
+There are thought to be around 316,000 western gorillas in the wild, and 5,000 eastern gorillas. Both species are classified as Critically Endangered by the IUCN; all subspecies are classified as Critically Endangered with the exception of the mountain gorilla, which is classified as Endangered. There are many threats to their survival, such as poaching, habitat destruction, and disease, which threaten the survival of the species. However, conservation efforts have been successful in some areas where they live.
+
+
+== Etymology ==
+
+The word "gorilla" comes from the history of Hanno the Navigator (c.  500 BC), a Carthaginian explorer on an expedition to the west African coast to the area that later became Sierra Leone. Members of the expedition encountered "savage people, the greater part of whom were women, whose bodies were hairy, and whom our interpreters called Gorillae". It is unknown whether what the explorers encountered were what we now call gorillas, another species of ape or monkeys, or humans. Skins of gorillai women, brought back by Hanno, are reputed to have been kept at Carthage until Rome destroyed the city 350 years later at the end of the Punic Wars, 146 BC.
+The American physician and missionary Thomas Staughton Savage and naturalist Jeffries Wyman first described the western gorilla in 1847 from specimens obtained in Liberia. They called it Troglodytes gorilla, using the then-current name of the chimpanzee genus.  The species name was derived from Ancient Greek  Γόριλλαι (gorillai)  'tribe of hairy women', as described by Hanno.
+
+
+== Evolution and classification ==
+The closest relatives of gorillas are the other two Homininae genera, chimpanzees and humans, all of them having diverged from a common ancestor about 7 million years ago. Human gene sequences differ only 1.6% on average from the sequences of corresponding gorilla genes, but there is further difference in how many copies each gene has. Until recently, gorillas were considered to be a single species, with three subspecies: the western lowland gorilla, the eastern lowland gorilla and the mountain gorilla. There is now agreement that there are two species, each with two subspecies. More recently, a third subspecies has been claimed to exist in one of the species. The separate species and subspecies developed from a single type of gorilla during the Ice Age, when their forest habitats shrank and became isolated from each other.Primatologists continue to explore the relationships between various gorilla populations. The species and subspecies listed here are the ones upon which most scientists agree.
+The proposed third subspecies of Gorilla beringei, which has not yet received a trinomen, is the Bwindi population of the mountain gorilla, sometimes called the Bwindi gorilla.
+Some variations that distinguish the classifications of gorilla include varying density, size, hair colour, length, culture, and facial widths. Population genetics of the lowland gorillas suggest that the western and eastern lowland populations diverged around 261 thousand years ago.
+
+
+== Characteristics ==
+
+Wild male gorillas weigh 136 to 227 kg (300 to 500 lb), while adult females weigh 68–113 kg (150–250 lb). Adult males are 1.4 to 1.8 m (4 ft 7 in to 5 ft 11 in) tall, with an arm span that stretches from 2.3 to 2.6 m (7 ft 7 in to 8 ft 6 in). Female gorillas are shorter at 1.25 to 1.5 m (4 ft 1 in to 4 ft 11 in), with smaller arm spans. Colin Groves (1970) calculated the average weight of 42 wild adult male gorillas at 144 kg, while Smith and Jungers (1997) found the average weight of 19 wild adult male gorillas to be 169 kg. Adult male gorillas are known as silverbacks due to the characteristic silver hair on their backs reaching to the hips. The tallest gorilla recorded was a 1.95 m (6 ft 5 in) silverback with an arm span of 2.7 m (8 ft 10 in), a chest of 1.98 m (6 ft 6 in), and a weight of 219 kg (483 lb), shot in Alimbongo, northern Kivu in May 1938. The heaviest gorilla recorded was a 1.83 m (6 ft 0 in) silverback shot in Ambam, Cameroon, which weighed 267 kg (589 lb). Males in captivity can be overweight and reach weights up to 310 kg (683 lb).
+
+The eastern gorilla is more darkly coloured than the western gorilla, with the mountain gorilla being the darkest of all. The mountain gorilla also has the thickest hair. The western lowland gorilla can be brown or greyish with a reddish forehead. In addition, gorillas that live in lowland forest are more slender and agile than the more bulky mountain gorillas. The eastern gorilla also has a longer face and broader chest than the western gorilla. Like humans, gorillas have individual fingerprints.
+Their eye colour is dark brown, framed by a black ring around the iris. Gorilla facial structure is described as mandibular prognathism, that is, the mandible protrudes farther out than the maxilla. Adult males also have a prominent sagittal crest.
+Gorillas move around by knuckle-walking, although they sometimes walk upright for short distances, typically while carrying food or in defensive situations. A 2018 study investigating the hand posture of 77 mountain gorillas at Bwindi Impenetrable National Park (8% of the population) found that knuckle walking was done only 60% of the time, and they also supported their weight on their fists, the backs of their hands/feet, and on their palms/soles (with the digits flexed). Such a range of hand postures was previously thought to have been used by only orangutans. Studies of gorilla handedness have yielded varying results, with some arguing for no preference for either hand, and others right-hand dominance for the general population.Studies have shown gorilla blood is not reactive to anti-A and anti-B monoclonal antibodies, which would, in humans, indicate type O blood. Due to novel sequences, though, it is different enough to not conform with the human ABO blood group system, into which the other great apes fit.A gorilla's lifespan is normally between 35 and 40 years, although zoo gorillas may live for 50 years or more. Colo, a female western gorilla at the Columbus Zoo and Aquarium, was the oldest known gorilla at 60 years of age when she died on 17 January 2017. Ozzie was 61 years old at the time of his death in January 2022.
+
+
+== Distribution and habitat ==
+
+Gorillas have a patchy distribution. The range of the two species is separated by the Congo River and its tributaries. The western gorilla lives in west central Africa, while the eastern gorilla lives in east central Africa. Between the species, and even within the species, gorillas live in a variety of habitats and elevations. Gorilla habitat ranges from montane forest to swampland. Eastern gorillas inhabit montane and submontane forests between 650 and 4,000 m (2,130 and 13,120 ft) above sea level.Mountain gorillas live in montane forests at the higher end of the elevation range, while eastern lowland gorillas live in submontane forests at the lower end. In addition, eastern lowland gorillas live in montane bamboo forests, as well as lowland forests ranging from 600–3,308 m (1,969–10,853 ft) in elevation. Western gorillas live in both lowland swamp forests and montane forests, at elevations ranging from sea level to 1,600 m (5,200 ft). Western lowland gorillas live in swamp and lowland forests ranging up to 1,600 m (5,200 ft), and Cross River gorillas live in low-lying and submontane forests ranging from 150–1,600 m (490–5,250 ft).
+
+
+== Ecology ==
+
+
+=== Diet and foraging ===
+
+A gorilla's day is divided between rest periods and travel or feeding periods. Diets differ between and within species. Mountain gorillas mostly eat foliage, such as leaves, stems, pith, and shoots, while fruit makes up a very small part of their diets. Mountain gorilla food is widely distributed and neither individuals nor groups have to compete with one another. Their home ranges vary from 3 to 15 km2 (1.2 to 5.8 sq mi), and their movements range around 500 m (0.31 mi) or less on an average day. Despite eating a few species in each habitat, mountain gorillas have flexible diets and can live in a variety of habitats.
+
+Eastern lowland gorillas have more diverse diets, which vary seasonally. Leaves and pith are commonly eaten, but fruits can make up as much as 25% of their diets. Since fruit is less available, lowland gorillas must travel farther each day, and their home ranges vary from 2.7 to 6.5 km2 (1.0 to 2.5 sq mi), with day ranges 154–2,280 m (0.096–1.417 mi). Eastern lowland gorillas will also eat insects, preferably ants. Western lowland gorillas depend on fruits more than the others and they are more dispersed across their range. They travel even farther than the other gorilla subspecies, at 1,105 m (0.687 mi) per day on average, and have larger home ranges of 7–14 km2 (2.7–5.4 sq mi). Western lowland gorillas have less access to terrestrial herbs, although they can access aquatic herbs in some areas. Termites and ants are also eaten.
+Gorillas rarely drink water "because they consume succulent vegetation that is comprised of almost half water as well as morning dew", although both mountain and lowland gorillas have been observed drinking.
+
+
+=== Nesting ===
+
+Gorillas construct nests for daytime and night use. Nests tend to be simple aggregations of branches and leaves about 2 to 5 ft (0.61 to 1.52 m) in diameter and are constructed by individuals. Gorillas, unlike chimpanzees or orangutans, tend to sleep in nests on the ground. The young nest with their mothers, but construct nests after three years of age, initially close to those of their mothers. Gorilla nests are distributed arbitrarily and use of tree species for site and construction appears to be opportunistic. Nest-building by great apes is now considered to be not just animal architecture, but as an important instance of tool use.Gorillas make a new nest to sleep on daily and do not use the previous one. This even if remaining in the same place. Usually, they are made an hour before dusk, to be ready to sleep when night falls. Gorillas sleep longer than humans, an average of 12 hours per day.
+
+
+=== Threats and competition ===
+One possible predator of gorillas is the leopard. Gorilla remains have been found in leopard scat, but this may be the result of scavenging. When the group is attacked by humans, leopards, or other gorillas, an individual silverback will protect the group, even at the cost of his own life. Gorillas do not appear to directly compete with chimpanzees in areas where they overlap. When fruit is abundant gorilla and chimpanzee diets converge, but when fruit is scarce gorillas resort to vegetation. The two apes may also feed on different species, whether fruit or insects. Gorillas and chimpanzees usually ignore or avoid each other when feeding on the same tree, but coalitions of chimpanzees have been observed attacking families of gorillas including silverbacks and killing infants.
+
+
+== Behaviour ==
+
+
+=== Social structure ===
+
+Gorillas live in groups called troops. Troops tend to be made of one adult male or silverback, with a harem of multiple adult females and their offspring. However, multiple-male troops also exist. A silverback is typically more than 12 years of age, and is named for the distinctive patch of silver hair on his back, which comes with maturity. Silverbacks have large canine teeth that also come with maturity. Both males and females tend to emigrate from their natal groups. For mountain gorillas, females disperse from their natal troops more than males. Mountain gorillas and western lowland gorillas also commonly transfer to second new groups.Mature males also tend to leave their groups and establish their own troops by attracting emigrating females. However, male mountain gorillas sometimes stay in their natal troops and become subordinate to the silverback. If the silverback dies, these males may be able to become dominant or mate with the females. This behaviour has not been observed in eastern lowland gorillas. In a single male group, when the silverback dies, the females and their offspring disperse and find a new troop. Without a silverback to protect them, the infants will likely fall victim to infanticide. Joining a new group is likely to be a tactic against this. However, while gorilla troops usually disband after the silverback dies, female eastern lowlands gorillas and their offspring have been recorded staying together until a new silverback transfers into the group. This likely serves as protection from leopards.
+
+The silverback is the centre of the troop's attention, making all the decisions, mediating conflicts, determining the movements of the group, leading the others to feeding sites, and taking responsibility for the safety and well-being of the troop. Younger males subordinate to the silverback, known as blackbacks, may serve as backup protection. Blackbacks are aged between 8 and 12 years and lack the silver back hair. The bond that a silverback has with his females forms the core of gorilla social life. Bonds between them are maintained by grooming and staying close together. Females form strong relationships with males to gain mating opportunities and protection from predators and infanticidal outside males. However, aggressive behaviours between males and females do occur, but rarely lead to serious injury. Relationships between females may vary. Maternally related females in a troop tend to be friendly towards each other and associate closely. Otherwise, females have few friendly encounters and commonly act aggressively towards each other.Females may fight for social access to males and a male may intervene. Male gorillas have weak social bonds, particularly in multiple-male groups with apparent dominance hierarchies and strong competition for mates. Males in all-male groups, though, tend to have friendly interactions and socialise through play, grooming, and staying together, and occasionally they even engage in homosexual interactions. Severe aggression is rare in stable groups, but when two mountain gorilla groups meet the two silverbacks can sometimes engage in a fight to the death, using their canines to cause deep, gaping injuries.
+
+
+=== Reproduction and parenting ===
+
+Females mature at 10–12 years (earlier in captivity), and males at 11–13 years. A female's first ovulatory cycle occurs when she is six years of age, and is followed by a two-year period of adolescent infertility. The estrous cycle lasts 30–33 days, with outward ovulation signs subtle compared to those of chimpanzees. The gestation period lasts 8.5 months. Female mountain gorillas first give birth at 10 years of age and have four-year interbirth intervals. Males can be fertile before reaching adulthood. Gorillas mate year round.Females will purse their lips and slowly approach a male while making eye contact. This serves to urge the male to mount her. If the male does not respond, then she will try to attract his attention by reaching towards him or slapping the ground. In multiple-male groups, solicitation indicates female preference, but females can be forced to mate with multiple males. Males incite copulation by approaching a female and displaying at her or touching her and giving a "train grunt". Recently, gorillas have been observed engaging in face-to-face sex, a trait once considered unique to humans and bonobos.
+
+Gorilla infants are vulnerable and dependent, thus mothers, their primary caregivers, are important to their survival. Male gorillas are not active in caring for the young, but they do play a role in socialising them to other youngsters. The silverback has a largely supportive relationship with the infants in his troop and shields them from aggression within the group. Infants remain in contact with their mothers for the first five months and mothers stay near the silverback for protection. Infants suckle at least once per hour and sleep with their mothers in the same nest.Infants begin to break contact with their mothers after five months, but only for a brief period each time. By 12 months old, infants move up to five m (16 ft) from their mothers. At around 18–21 months, the distance between mother and offspring increases and they regularly spend time away from each other. In addition, nursing decreases to once every two hours. Infants spend only half of their time with their mothers by 30 months. They enter their juvenile period at their third year, and this lasts until their sixth year. At this time, gorillas are weaned and they sleep in a separate nest from their mothers. After their offspring are weaned, females begin to ovulate and soon become pregnant again. The presence of play partners, including the silverback, minimizes conflicts in weaning between mother and offspring.
+
+
+=== Communication ===
+
+Twenty-five distinct vocalisations are recognised, many of which are used primarily for group communication within dense vegetation. Sounds classified as grunts and barks are heard most frequently while traveling, and indicate the whereabouts of individual group members. They may also be used during social interactions when discipline is required. Screams and roars signal alarm or warning, and are produced most often by silverbacks. Deep, rumbling belches suggest contentment and are heard frequently during feeding and resting periods. They are the most common form of intragroup communication.For this reason, conflicts are most often resolved by displays and other threat behaviours that are intended to intimidate without becoming physical. As a result, fights do not occur very frequently. The ritualized charge display is unique to gorillas. The entire sequence has nine steps: (1) progressively quickening hooting, (2) symbolic feeding, (3) rising bipedally, (4) throwing vegetation, (5) chest-beating with cupped hands, (6) one leg kick, (7) sideways running, two-legged to four-legged, (8) slapping and tearing vegetation, and (9) thumping the ground with palms to end display.A gorilla's chest-beat may vary in frequency depending on its size. Smaller ones tend to have higher frequencies, while larger ones tend to be lower. They also do it the most when females are ready to mate.
+
+
+== Intelligence ==
+
+Gorillas are considered highly intelligent. A few individuals in captivity, such as Koko, have been taught a subset of sign language. Like the other great apes, gorillas can laugh, grieve, have "rich emotional lives", develop strong family bonds, make and use tools, and think about the past and future. Some researchers believe gorillas have spiritual feelings or religious sentiments. They have been shown to have cultures in different areas revolving around different methods of food preparation, and will show individual colour preferences.
+
+
+=== Tool use ===
+
+The following observations were made by a team led by Thomas Breuer of the Wildlife Conservation Society in September 2005. Gorillas are now known to use tools in the wild. A female gorilla in the Nouabalé-Ndoki National Park in the Republic of Congo was recorded using a stick as if to gauge the depth of water whilst crossing a swamp. A second female was seen using a tree stump as a bridge and also as a support whilst fishing in the swamp. This means all of the great apes are now known to use tools.In September 2005, a two-and-a-half-year-old gorilla in the Republic of Congo was discovered using rocks to smash open palm nuts inside a game sanctuary. While this was the first such observation for a gorilla, over 40 years previously, chimpanzees had been seen using tools in the wild 'fishing' for termites. Nonhuman great apes are endowed with semiprecision grips, and have been able to use both simple tools and even weapons, such as improvising a club from a convenient fallen branch.
+
+
+== Scientific study ==
+American physician and missionary Thomas Staughton Savage obtained the first specimens (the skull and other bones) during his time in Liberia. The first scientific description of gorillas dates back to an article by Savage and the naturalist Jeffries Wyman in 1847 in Proceedings of the Boston Society of Natural History, where Troglodytes gorilla is described, now known as the western gorilla. Other species of gorilla were described in the next few years.
+
+The explorer Paul Du Chaillu was the first westerner to see a live gorilla during his travel through western equatorial Africa from 1856 to 1859. He brought dead specimens to the UK in 1861.The first systematic study was not conducted until the 1920s, when Carl Akeley of the American Museum of Natural History traveled to Africa to hunt for an animal to be shot and stuffed. On his first trip, he was accompanied by his friends Mary Bradley, a mystery writer, her husband, and their young daughter Alice, who would later write science fiction under the pseudonym James Tiptree Jr. After their trip, Mary Bradley wrote On the Gorilla Trail. She later became an advocate for the conservation of gorillas, and wrote several more books (mainly for children). In the late 1920s and early 1930s, Robert Yerkes and his wife Ava helped further the study of gorillas when they sent Harold Bigham to Africa. Yerkes also wrote a book in 1929 about the great apes.
+After World War II, George Schaller was one of the first researchers to go into the field and study primates. In 1959, he conducted a systematic study of the mountain gorilla in the wild and published his work. Years later, at the behest of Louis Leakey and the National Geographic, Dian Fossey conducted a much longer and more comprehensive study of the mountain gorilla. When she published her work, many misconceptions and myths about gorillas were finally disproved, including the myth that gorillas are violent.
+Western lowland gorillas (G. g. gorilla) are believed to be one of the zoonotic origins of HIV/AIDS. The SIVgor Simian immunodeficiency virus that infects them is similar to a certain strain of HIV-1.
+
+
+=== Genome sequencing ===
+The gorilla became the next-to-last great ape genus to have its genome sequenced. The first gorilla genome was generated with short read and Sanger sequencing using DNA from a female western lowland gorilla named Kamilah. This gave scientists further insight into the evolution and origin of humans. Despite the chimpanzees being the closest extant relatives of humans, 15% of the human genome was found to be more like that of the gorilla. In addition, 30% of the gorilla genome "is closer to human or chimpanzee than the latter are to each other; this is rarer around coding genes, indicating pervasive selection throughout great ape evolution, and has functional consequences in gene expression." Analysis of the gorilla genome has cast doubt on the idea that the rapid evolution of hearing genes gave rise to language in humans, as it also occurred in gorillas.
+
+
+== Captivity ==
+
+Gorillas became highly prized by western zoos since the 19th century, though the earliest attempts to keep them in captive facilities ended in their early death. In the late 1920s the care of captive gorillas significantly improved. Colo (December 22, 1956 – January 17, 2017) of the Columbus Zoo and Aquarium was the first gorilla to be born in captivity.Captive gorillas exhibit stereotypic behaviors, including eating disorders — such as regurgitation, reingestion and coprophagy — self-injurious or conspecific aggression, pacing, rocking, sucking of fingers or lip smacking, and overgrooming. Negative vigilance of visitor behaviors have been identified as starting, posturing and charging at visitors. Groups of bachelor gorillas containing young silverbacks have significantly higher levels of aggression and wounding rates than mixed age and sex groups.The use of both internal and external privacy screens on exhibit windows has been shown to alleviate stresses from visual effects of high crowd densities, leading to decreased stereotypic behaviors in the gorillas. Playing naturalistic auditory stimuli as opposed to classical music, rock music, or no auditory enrichment (which allows for crowd noise, machinery, etc. to be heard) has been noted to reduce stress behavior as well. Enrichment modifications to feed and foraging, where clover-hay is added to an exhibit floor, decrease stereotypic activities while simultaneously increasing positive food-related behaviors.Recent research on captive gorilla welfare emphasizes a need to shift to individual assessments instead of a one-size-fits-all group approach to understanding how welfare increases or decreases based on a variety of factors. Individual characteristics such as age, sex, personality and individual histories are essential in understanding that stressors will affect each individual gorilla and their welfare differently.
+
+
+== Conservation status ==
+
+All species (and subspecies) of gorilla are listed as endangered or critically endangered on the IUCN Red List. All gorillas are listed in Appendix I of the Convention on International Trade in Endangered Species (CITES), meaning that international export/import of the species, including in parts and derivatives, is regulated. Around 316,000 western lowland gorillas are thought to exist in the wild, 4,000 in zoos, thanks to conservation; eastern lowland gorillas have a population of under 5,000 in the wild and 24 in zoos. Mountain gorillas are the most severely endangered, with an estimated population of about 880 left in the wild and none in zoos. Threats to gorilla survival include habitat destruction and poaching for the bushmeat trade. Gorillas are closely related to humans, and are susceptible to diseases that humans also get infected by. In 2004, a population of several hundred gorillas in the Odzala National Park, Republic of Congo was essentially wiped out by the Ebola virus. A 2006 study published in Science concluded more than 5,000 gorillas may have died in recent outbreaks of the Ebola virus in central Africa. The researchers indicated in conjunction with commercial hunting of these apes, the virus creates "a recipe for rapid ecological extinction". In captivity, its also been observed that gorillas can also be infected with COVID-19.Conservation efforts include the Great Apes Survival Project, a partnership between the United Nations Environment Programme and the UNESCO, and also an international treaty, the Agreement on the Conservation of Gorillas and Their Habitats, concluded under UNEP-administered Convention on Migratory Species. The Gorilla Agreement is the first legally binding instrument exclusively targeting gorilla conservation; it came into effect on 1 June 2008. Governments of countries where gorillas live placed a ban on their killing and trading, but weak law enforcement still poses a threat to them, since the governments rarely apprehend poachers, traders and consumers that rely on gorillas for profit.
+
+
+== Cultural significance ==
+
+In Cameroon's Lebialem highlands, folk stories connect people and gorillas via totems; a gorilla's death means the connected person will die also. This creates a local conservation ethic. Many different indigenous peoples interact with wild gorillas. Some have detailed knowledge; the Baka have words to distinguish at least ten types of gorilla individuals, by sex, age, and relationships. In 1861, alongside tales of hunting enormous gorillas, the traveller and anthropologist Paul Du Chaillu reported the Cameroonian story that a pregnant woman who sees a gorilla will give birth to one.In 1911, the anthropologist Albert Jenks noted the Bulu people's knowledge of gorilla behaviour and ecology, and their gorilla stories. In one such story, "The Gorilla and the Child", a gorilla speaks to people, seeking help and trust, and stealing a baby; a man accidentally kills the baby while attacking the gorilla. Even far from where gorillas live, savannah tribes pursue "cult-like worship" of the apes. Some beliefs are widespread among indigenous peoples. The Fang name for gorilla is ngi while the Bulu name is njamong; the root ngi means fire, denoting a positive energy. From the Central African Republic to Cameroon and Gabon, stories of reincarnations as gorillas, totems, and transformations similar to those recorded by Du Chaillu are still told in the 21st century.Since gaining international attention, gorillas have been a recurring element of many aspects of popular culture and media. They were usually portrayed as murderous and aggressive. Inspired by Emmanuel Frémiet's Gorilla Carrying off a Woman, gorillas have been depicted kidnapping human women. This theme was used in films such as Ingagi (1930) and most notably King Kong (1933). The comedic play The Gorilla, which debuted in 1925, featured an escaped gorilla taking a woman from her house. Several films would use the "escaped gorilla" trope including The Strange Case of Doctor Rx (1942), The Gorilla Man (1943), Gorilla at Large (1954) and the Disney cartoons The Gorilla Mystery (1930) and Donald Duck and the Gorilla (1944).Gorillas have been used as opponents to jungle-themed heroes such as Tarzan and Sheena, Queen of the Jungle, as well as superheroes. The DC comics supervillain Gorilla Grodd is an enemy of the Flash. Gorillas also serve as antagonists in the 1968 film Planet of the Apes. More positive and sympathetic portrayals of gorillas include the films Son of Kong (1933), Mighty Joe Young (1949), Gorillas in the Mist (1988) and Instinct (1999) and the 1992 novel Ishmael. Gorillas have been featured in video games as well, notably Donkey Kong.

+The Victoria crowned pigeon (Goura victoria) is a large, bluish-grey pigeon with elegant blue lace-like crests, maroon breast and red irises. It is part of a genus (Goura) of four unique, very large, ground-dwelling pigeons native to the New Guinea region. The bird may be easily recognized by the unique white tips on its crests and by its deep 'whooping' sounds made while calling. Its name commemorates the British monarch Queen Victoria.
+
+
+== Description ==
+The Victoria crowned pigeon is a deep blue-grey colour with a small, black mask. Its feather crest (the signature feature of crowned pigeons other than their size) is conspicuously white-tipped. On the wing coverts is a row of feathers that are a paler blue-gray with maroon tips. These form a distinct wing bar. The chest is a deep purple-maroon color. As in all crowned pigeons, melanism has been observed. The other two crowned pigeons are somewhat superficially similar, but only the western crowned pigeon overlaps in range with the Victoria species. The Scheepmaker's crowned pigeon does not. In the western species, the crown is more scraggly and hair-like, the chest is a uniform blue-gray and not maroon, and a less distinct wing-bar is present. Both sexes are similar.This species is typically 73 to 75 cm (29 to 30 in) long. Some specimens may exceed a length of 80 cm (31 in) and a weight of 3.5 kg (7.7 lb). It is marginally larger than the two other crowned pigeons on average, at an mean of 2.39 kg (5.3 lb) in adult body mass, thus is considered the largest surviving species of pigeon of Earth. The standard measurements among pigeons on mainland New Guinea are: the wing chord is 36–39 cm (14–15 in), the tail is 27–30.1 cm (10.6–11.9 in), the bill is 3.2–3.5 cm (1.3–1.4 in) and the unfeathered tarsus is 8.5–9.8 cm (3.3–3.9 in).Like other crowned pigeons, this species makes a loud clapping sound when it takes flight. The mating calls of this species are also similar to the other two species of crowned pigeons, consisting of a deep hoota-hoota-hoota-hoota-hoota sound. When defending their territories, these birds make a resounding whup-up, whup-up, whup-up call. Their contact call is a deep, muffled, and rather human-like ummm or hmmm.The two subspecies of the Victoria crowned pigeon are  G. v. beccarii found on the mainland of New Guinea and G. v. victoria, the nominate race, found on the islands of Yapen, Biak and Supiori. The nominate subspecies is markedly smaller, with a wing chord measurement of 31.6–33.2 cm (12.4–13.1 in), with less robust legs and feet and darker overall plumage. The nominate has a sparser crest with black on the wing coverts and right above the tail.
+
+
+== Habitat ==
+The Victoria crowned pigeon is distributed in the lowland and swamp forests of northern New Guinea and surrounding islands. It usually occurs on areas that were former alluvial plains, including sago forests. Though typically found at or near sea level, occasionally birds of this species may venture up in the hills to an elevation up to about 3,000 feet.
+They fly from sea to tree every day. 
+
+
+== Behavior ==
+
+Like other crowned pigeons, the Victoria crowned pigeon is a gregarious species. They usually travel in pairs or small parties as they search for food. They walk with an unhurried gait along the forest floor. Their food typically consists of fallen fruit. Birds of this species in captivity are particularly fond of eating figs. Seeds and invertebrates may occasionally supplement the diet. When disturbed, these birds fly straight up into the canopy or a large horizontal branch of a large forest tree. After being disturbed, they may remain on their perch for a considerable time engaging in contact calls and flicking their tails. In the wild, this species tends to be shier than the western crowned pigeon, but can still occasionally be quietly approached. The males regularly engage in aggressive displays to establish dominance. In these interactions, the pigeons puff up their chests and repeatedly raise their wings as if preparing to strike their opponent. They also make short dashes at each other and may actually hit one another, but rarely make contact and can be completely peaceful towards other males outside of the early mating season.
+
+
+== Reproduction ==
+Breeding peaks late in wet season and in the dry season. When the male displays for the female, he lowers his head down, stretches forward, and then rhythmically swings his head up and down while simultaneously wagging his fanned tail. Although the female does most direct brooding, both parents help raise the young. The female usually lays a single white egg in a well-built tree nest of stems, sticks, and palm leaves. In the weeks before she lays the egg, the male brings nesting material to the female. The egg is incubated around 30 days. The young leave the nest when they are still much smaller than their parents but are actively tended to for a total of 13 weeks.
+
+
+== Status ==
+The Victoria crowned pigeon is now the most rarely occurring of the three crowned pigeon species in the wild, although it is the most widely kept species in captivity. Perhaps the most pressing threat to the species is continuing habitat loss due to logging. It now quite uncommon near human habitations because it is heavily hunted around them, particularly in areas where gun possession is prevalent. It can be quite tame and easily shot, though it now seems to be fearful of humans in the wild. Most hunting is for its plumes and meat. Trapping of pigeons to be kept alive for captive collections is now illegal but is still likely to be occurring. The Victoria crowned pigeon is evaluated as Near Threatened on the IUCN Red List of Threatened Species. It is listed in Appendix II of CITES.

+Graptemys is a genus of freshwater turtles containing 14 species, commonly known as map turtles.  Graptemys are small to medium-sized turtles that are sexually dimorphic, with females attaining as much as twice the length and ten times the mass as males in some species. Depending on the species, adult males range from 7–16 cm (2.75–6.25 in), adult females 10–29.5 cm (4–11.62 in), and hatchlings 2.5–3.8 cm (1–1.5 in),: 202–209 p.  although some sources indicate female Barbour's map turtles (Graptemys barbouri) grow to 33 cm (13 in) in length.   Most species have a distinctive dark pigmented keel that is often notched or serrated running down the center of the carapace and serrated scutes on the rear margin. The head, neck, and limbs exhibit bold patterns of yellow (occasionally orange or red) lines and spots against darker green, olive, or black base colors. The patterns on the head can be important characters in identifying the various species. The common name "map turtle" is derived from the intricate patterns on their shells that are suggestive of topographical maps, although the patterns are more apparent in some species than others, and often become obscure in older specimens. Some species are occasionally called "sawbacks", in reference to the serrated keels on their shell.They are endemic to North America, where most species occur in the rivers of the Gulf Coast of the United States, although three species are more wide-ranging, dispersed throughout the eastern two thirds of the greater Mississippi River basin, into the Great Lakes region, and east to New York and southeast Canada. Most Graptemys are lotic, river turtles, having a preference for moving water and larger lakes, and with long legs, broad feet, and long fully webbed digits they are well adapted for swimming in currents. They primarily feed on fresh water mussels, clams, snails, insects (including larva and eggs), bryozoans, sponges, algae, and various vegetation. Fish only appear in the diets of a few species and then only in a relatively small percentage of the diet. Within this spectrum of food items there is significant niche partitioning among the sexually dimorphic males and females, and microcephalic, mesocephalic, and megacephalic species occurring in the same river drainages. Like all turtles, map turtles are oviparous, typically laying eggs from late June to August. Females lay two to 15 eggs per clutch and depending on a number of variables such as species, size, and age among other factors, may skip a year between clutches, or lay as many four clutches a year.Seven of the 14 species are listed as either near threatened, vulnerable, or endangered by the IUCN Red List as of 2021, and two species, the yellow-blotched map turtle (G. flavimaculata) and the ringed map turtle (G. oculifera) are listed as threatened by the U.S. Federal Government.
+

+
+†Graptemys kerneri Ehret & Bourque, 2011
+
+
+== Etymology ==
+
+The generic name Graptemys is derived from two compounded Greek words, graptos, meaning inscribed or in writing, in reference to the patterns on the turtles shells, and emydos, meaning a freshwater turtle. The trivial names, or specific epithets, of four of the species in the genus are patronyms or eponyms, named in honor of prominent herpetologist, each of whom made significant contributions to studies on North American turtles: Thomas Barbour (G. barbouri); Fred Ray Cagle (G. caglei); Carl Henry Ernst (G. ernsti); J. Whitfield Gibbons (G. gibbonsi). One subspecies is named for the collector of the type specimen, Joseph Gustave Kohn (G. pseudogeographica kohnii). Three species are named for the rivers in which they were first discovered: Ouachita River (G. ouachitensis); Sabine River (G. sabinensis); Pearl River (G. pearlensis). The other species are all named for various aspects of the topographic map like patterns and other markings, colors, and contours of the carapace, that are most apparent in the juveniles and young adults of these attractive turtles: G. flavimaculata, flavus = yellow, maculatus = spotted or blotched; G. geographica, geographica = geographic map like; G.  nigrinoda, niger = black, nodus = knot, node, or knob; G. oculifera, oculus = eye, fero = to bear (eye shape rings on the pleurals scutes); G. pseudogeographica, pseudo = false, geographica = geographic map like; G. pulchra, pulchra = beautiful; G. versa, vers = to change (probably referring to the contrasting head patterns compared to G. pseudogeographica).
+
+
+== Description ==
+
+Graptemys species superficially resemble many other species of aquatic turtles, including sliders (Trachemys) and cooters (Pseudemys).  However, they are distinguished by a keel that runs the length of the center of the carapace. In some southern species, the keel can result in vertebral spines, resulting in the map turtle's other common name — "sawback". They also typically grow to a smaller size at maturity. They are given the common name "map turtle" due to the map-like markings on the carapace. Map turtles are known for intricate head markings and strong sexual dimorphism with mature females twice the length and 10 times the mass of mature males.
+
+
+=== Feeding morphology ===
+Females of all map turtle species can be partitioned into three groups based on head (alveolar) width and corresponding ecology and phylogeny.
+
+Microcephalic females are narrow headed, sympatric with a broader headed species, and consume few mollusks.  Microcephalic species include yellow-blotched, black-knobbed, ringed, Ouachita, and Sabine map turtles.
+Mesocephalic females have moderately broad heads and tend to eat mostly mollusks along with softer bodied prey. Mesocephalic species include Cagle's, northern, false, Mississippi, and Texas map turtles.
+Megacephalic females have exceptionally broad heads, and feed almost exclusively on mollusks. Megacephalic females include Barbour's, Escambia, Pascagoula, Pearl River, and Alabama map turtles.Males do not fit neatly into the three groups describing head width, with differences in head width likely not influencing diet.
+Due to these differences in head size and jaw strength, females tend to eat much larger prey than the males such as snails, clams, and crayfish whereas the males eat insects and smaller crustaceans.: 237 p.    
+Including deadwood material inside of the Graptemys habitat then the chances of more Graptemys migrating or being born in that area is greater. The population can use a healthy habitat that can support a significant number of Graptemys and dead wood will help with this.
+
+
+== Distribution ==
+
+Map turtles are endemic to North America. The genus ranges from the Great Lakes region and St. Lawrence River of southern Quebec and Ontario, Canada, south to the Gulf of Mexico, and the Hudson River and Delaware River basins on the Atlantic coast, west to the eastern margins of the Great Plains. Most species occur in rivers, moving waters, or larger lakes. Eleven of the 14 species have relatively limited distributions, restricted to river basins draining into the Gulf of Mexico, in the US states of Texas, Louisiana, Mississippi, Alabama, southwest Georgia, and the Florida panhandle. Three species are more wide ranging, include the Ouachita Map Turtle (G. ouachitensis) and the False Map Turtle (G. pseudogeographica) which range extensively in the Mississippi River drainage and its tributaries including much of the mid west, with the latter also ranging west into east Texas. The Northern Map Turtle (G. geographica) is the most widespread species, occurring in both Atlantic and Gulf of Mexico river drainages, from southern Quebec, Canada, west to Minnesota and eastern Kansas, south to New Jersey and above (north) of the fall line in Georgia, Alabama, and extreme northern Louisiana.: 202–209 pp. 
+
+
+== Ecology and natural history ==
+
+
+=== Habitat ===
+Map turtles are predominantly lotic, living in moving water, such as rivers and larger creeks, streams, and bayous. The northern and wide-ranging Mississippi River species (G. geographica, G. pseudogeographica, G. ouachitensis) tend to inhabit more diverse habitats, including sloughs, oxbow lakes, and backwater areas of river bottoms, as well as lakes and occasionally even ponds and marshlands. Other species use these environments much less frequently, or as juveniles or during seasonal flooding, and a few species have never been reported from areas beyond the main channels of their respective river systems (e.g. G. gibbonsi, G. pearlensis, G. sabinensis). Several species will inhabit manmade reservoirs in their river systems, while other species are very uncommon in such impoundments (e.g. G. oculifera, G. versa), and still others are entirely absent from reservoirs (e. g. G. caglei). With few exceptions (G. barbouri, G. flavimaculata, G. nigrinoda), most species do not occur in tidally influenced waterways, estuaries, or brackish waters, which are occupied by their closest relative the diamondback terrapin (Malaclemys terrapin). The upstream distributional limits of many species are often associated with the level of sunlight penetration through the forest canopy. Larger, wider waterways allow sunlight to reach the surface, providing for the growth of aquatic vegetation and algae (food) and basking sites for Graptemys populations. Smaller streams in the shadow of forest canopies, or that receive brief patchy sunlight, are rarely inhabited by Graptemys.: 84–87, 255–360 pp. : 272–343 pp. 
+
+The ecology of many species of map turtles, particularly habitat use and diet, have been well studied. Specific habitat use often differs among males and females of the same species, as well as sympatric species sharing a river system, all inextricably linked to their diets in a somewhat complex example of  niche differentiation. Ten of the 14 Graptemys species share a river basin with another Graptemys species, and three species occur in regions of Alabama, and portions of the Mississippi River. Generally the mesocephalic and megacephalic females occupy deeper areas with stronger currents and hard-bottom, limestone sections of rivers, and males inhabit slower, shallower areas of the rivers nearer to the shore, largely correlated with their respective diets and prey distribution. Graptemys rarely walk on land or move between waterways. Most species are reluctant to bask on river banks and are seldom seen even on fallen trees with one end resting on the bank. Basking sites are most often fallen tree and deadwood emerging from water with no direct contact to the banks. Although the wide-ranging, northern species (G. geographica, G. pseudogeographica, G. ouachitensis) tend to be more flexible in their basking habits.: 84–87, 255–360 pp. : 272–343 pp. The natural meandering of rivers, riparian forest, and fallen trees and deadwood in the water are all key and vital elements to sustain most map turtle populations, particularly the Gulf Coast species. The outer bend in a river is typically the deeper side, with the stronger current of the main channel, eroding and cutting into the outer bank and falling trees of the riparian zone forest as it does. While the inside of the bend is shallower, with a slower current, dropping silt deposits and building beaches and sandbars. The meandering course maintains a diverse spectrum of water depths, temperatures, currents, soft and hardpan bottoms, as well as fallen trees and logs that get lodged in the bends. Beaches and sand bars are essential nesting sites. The presence of partially submerged deadwood and trees are critical, not only for basking, but for the growth of algae, bryozoans, sponges, snails, insects and their eggs larva that live in the growth, which are important food items for turtles.: 84–87, 255–360 pp. : 272–343 pp. 
+
+
+=== Courtship behavior ===
+Adult Graptemys males have greatly elongated claws on the front feet, which are used in courtship behavior.  The male faces the considerably larger female and "fans" her face, vibrating his foreclaws against her head to induce her to cooperate in mating.
+
+
+=== Longevity ===
+Complete and accurate longevity records for map turtles are lacking. A review of zoo records published in 1992 identified the maximum period of time that many species of Graptemys lived in captivity in North American zoos, ranging from eight to 35 years, including: Barbour's map turtle (G. barbouri) 31 years 8 months; false map turtle (G. pseudogeographica ssp.) 32 years and 6 months; Mississippi map turtle (G. pseudogeographica kohnii) 35 years 5 months. However, it is important to note that in every example these records involve turtles that were acquired by the zoos as adults from the wild, or of unknown origins and of undetermined ages. Therefore the records only reflect the period of time that an individual turtle was maintained at the institutions before it died, not the full lifespan of the individual.: 13 p.  Subsequently, the longevity of two female Barbour's Map Turtles (G. barbouri) of unknown ages and origin at the Columbus Zoo were reported at 37 and 43 years. Herpetologist Carl Ernst noted northern map turtles (G. geographica) and Alabama map turtles (G. pulchra) likely live well over 20 years in the wild,: 300 & 339 p.  and ringed map turtles (G. oculifera) are known to live at least 30 years in the wild. Based on records of other turtles in the Emydidae family, it is likely Graptemys longevity exceeds these records significantly, perhaps by decades.: 114 p. 
+
+
+== Conservation ==
+The most frequently cited and best-documented threats to map turtle and sawback populations involve modifications of the rivers and lakes they inhabit and their take for the pat trade.: 198 p. 
+
+The limited ranges and restricted habitats of most species make Graptemys particularly vulnerable to conservation issues. The destruction and fragmentation of habitat through the engineering of rivers and lakes, such as channelization, dams and impoundments, gravel and sand mining, pollution, clearing and development of riparian zones, and the removal of logs and deadwood from waterways are among the foremost conservation threats to map turtles. These activities degrade or destroy nesting sites (sandbars), prey species and prey habitat, and basking sites that are essential for thermoregulation and the turtles survival. The pet trade is another significant threat to the survival of map turtles. In the year in 2000 alone, 200,000 live Graptemys were exported from the USA, predominantly to Europe, and this does not take into account the domestic market.: 192–206 p. A variety of human activities such as bycatch in gillnetting and fyke nets, injuries form boat propellers, and "plinking", the practice of shooing turtles for target practice, or for the misinformed idea that they are significant competitors for game fish, all contribute to mortalities. Seemingly benign activities such as the regular use of sandbar beaches for recreation, swimming, and heavy boat traffic are known to cause turtles to abandon stretches of rivers and nesting sites. Some lesser threats include invasive species such as fire ants (Solenopsis invicta) which are known to prey on eggs and hatchlings. Invasive plants such as water hyacinth (Eichhornia crassipes), alligator weed (Alternanthera philoxeroides), congon grass (Imperata cylindrica), cocklebur (Xanthium stramarium), and the Chinese tallow tree (Triadica sebifera) are all known to degrade Graptemys habitat and nesting beaches. Hydrilla (Hydrilla verticillata) has been associated with steep declines of black-knobbed map turtles in some areas. Conversely, maps turtles are known to feed on some non-native species of clams (Corbicula) and mussels (Dreissena).: 210–214 p. The United States Federal Government list two species, the yellow-blotched map turtle (G. flavimaculata) and the ringed map turtle (G. oculifera) as threatened species. In Texas the state government list the Cagle's Map Turtle (G. caglei) as a threatened species. The state of Louisiana list the ringed map turtle (G. oculifera) as threatened and the Ouachita map turtle (G. ouachitensis) and Sabine Map Turtle (G. sabinensis) as vulnerable. The state of Mississippi list the yellow-blotched map turtle (G. flavimaculata) as threatened and the ringed map turtle (G. oculifera) and  black-knobbed map turtle (G. nigrinoda) as endangered. In Alabama, all six species of map turtles occurring in the state are classified as nongame species protected by the state. In Georgia the Barbour's map turtle (G. barbouri) is as threatened and the northern map turtle (G.  geographica) and Alabama map turtle (G. pulchra) are considered rare species ranked S1 and S3 respectively. In Florida Barbour's map turtle (G. barbouri) is state-designated as threatened. The Government of Canada list the Northern Map Turtle (G. geographica) is a species of special concern. Seven of the 14 Graptemys species are listed as either, near threatened, vulnerable, or endangered by the IUCN Red List as of 2021 As of 2021, all Graptemys are listed as Appendix III by CITES.
+
+
+== Pet trade ==
+Throughout the pet trade, the Mississippi map turtle, the northern map turtle, and Ouachita map turtle were bred and hatched out by the thousands in the 1970s. Various other turtles were available, but as the salmonellosis Four-inch Law was established, map turtles and others slowly decreased in popularity. Today, these same three still hold the title for most common among the pet trade. Other species being captive-bred more often include the Texas map turtle, Cagle's map turtle, and the black-knobbed map turtle. Some harder-to-find map turtles include the yellow-blotched map turtle and the Pearl River map turtle.

+The Ouachita map turtle (Graptemys ouachitensis) is a species of turtle belonging to the family Emydidae.
+
+
+== Subspecies ==
+Subspecies include:
+Graptemys ouachitensis ouachitensis Cagle, 1953
+Graptemys ouachitensis sabinensis Cagle, 1953In recent years the Sabine map turtle (Graptemys ouachitensis sabinensis) has been recognized by many as a full species Sabine map turtle (Graptemys sabinensis).
+
+
+== Distribution ==
+This species is endemic to the United States. It can be found in Texas, Louisiana, Mississippi, Alabama, Oklahoma, Kansas, Arkansas, Missouri, Iowa, Minnesota, Wisconsin, Indiana, Ohio, West Virginia, Illinois, Tennessee and Kentucky. G. o. sabinensis exists only in the Sabine River of Louisiana and Texas. Both G. o. ouachitensis and G. o. sabinensis are freshwater riverine turtles. The G. o. ouachitensis is rarely seen on land unless it is nesting season or it is basking. 
+
+
+== Description ==
+This species' carapace features a row of low vertebral spines, and is serrated on the posterior rim. The carapace is olive, dark brown, or black in coloration with light yellowish markings with dark borders. The plastron color varies from cream to yellow and is patterned with dark lines and swirls. The body color is grayish brown to blackish and is marked with yellowish stripes.On the head, it has light yellow spots: a rectangular one behind each eye, an oval under each eye, and a round one on each side of the jaw. In some specimens, the spot behind and the spot under the eye can combine to form a single thick "C" stain. The eye has a black stripe in the middle.Males are significantly smaller than females. The males can grow to be as large as 5 in (12 cm) in carapace length. The females can grow to be up to 10 in (25 cm) in carapace length.
+
+
+== Natural History ==
+Hatchlings of this species have recently been found to make sounds prior to exiting the nest. These are mostly "clicking" noises, but more tonal "mewing" sounds are also sometimes present. These sounds are the first documented for any North American hatchling turtle. (Geller, G.A. and G.S. Casper. 2019. Late-term embryos and hatchlings of Ouachita Map Turtles (Graptemys ouachitensis) make sounds within the nest. Herpetological Review 50:449-452)
+
+
+== Diet ==
+Ouachita map turtles feed mainly on small aquatic animals such as shrimp, insects, molluscs, and fish. They also consume algae and aquatic plants.
+
+
+== Pet trade ==
+As they are small, Ouachita map turtles are common among turtle keepers. They can be kept with most other species and can be raised on specialty pellets and dried shrimp. Although they need heat and ultraviolet light (UVB),

+Graptemys is a genus of freshwater turtles containing 14 species, commonly known as map turtles.  Graptemys are small to medium-sized turtles that are sexually dimorphic, with females attaining as much as twice the length and ten times the mass as males in some species. Depending on the species, adult males range from 7–16 cm (2.75–6.25 in), adult females 10–29.5 cm (4–11.62 in), and hatchlings 2.5–3.8 cm (1–1.5 in),: 202–209 p.  although some sources indicate female Barbour's map turtles (Graptemys barbouri) grow to 33 cm (13 in) in length.   Most species have a distinctive dark pigmented keel that is often notched or serrated running down the center of the carapace and serrated scutes on the rear margin. The head, neck, and limbs exhibit bold patterns of yellow (occasionally orange or red) lines and spots against darker green, olive, or black base colors. The patterns on the head can be important characters in identifying the various species. The common name "map turtle" is derived from the intricate patterns on their shells that are suggestive of topographical maps, although the patterns are more apparent in some species than others, and often become obscure in older specimens. Some species are occasionally called "sawbacks", in reference to the serrated keels on their shell.They are endemic to North America, where most species occur in the rivers of the Gulf Coast of the United States, although three species are more wide-ranging, dispersed throughout the eastern two thirds of the greater Mississippi River basin, into the Great Lakes region, and east to New York and southeast Canada. Most Graptemys are lotic, river turtles, having a preference for moving water and larger lakes, and with long legs, broad feet, and long fully webbed digits they are well adapted for swimming in currents. They primarily feed on fresh water mussels, clams, snails, insects (including larva and eggs), bryozoans, sponges, algae, and various vegetation. Fish only appear in the diets of a few species and then only in a relatively small percentage of the diet. Within this spectrum of food items there is significant niche partitioning among the sexually dimorphic males and females, and microcephalic, mesocephalic, and megacephalic species occurring in the same river drainages. Like all turtles, map turtles are oviparous, typically laying eggs from late June to August. Females lay two to 15 eggs per clutch and depending on a number of variables such as species, size, and age among other factors, may skip a year between clutches, or lay as many four clutches a year.Seven of the 14 species are listed as either near threatened, vulnerable, or endangered by the IUCN Red List as of 2021, and two species, the yellow-blotched map turtle (G. flavimaculata) and the ringed map turtle (G. oculifera) are listed as threatened by the U.S. Federal Government.

+
+†Graptemys kerneri Ehret & Bourque, 2011
+
+
+== Etymology ==
+
+The generic name Graptemys is derived from two compounded Greek words, graptos, meaning inscribed or in writing, in reference to the patterns on the turtles shells, and emydos, meaning a freshwater turtle. The trivial names, or specific epithets, of four of the species in the genus are patronyms or eponyms, named in honor of prominent herpetologist, each of whom made significant contributions to studies on North American turtles: Thomas Barbour (G. barbouri); Fred Ray Cagle (G. caglei); Carl Henry Ernst (G. ernsti); J. Whitfield Gibbons (G. gibbonsi). One subspecies is named for the collector of the type specimen, Joseph Gustave Kohn (G. pseudogeographica kohnii). Three species are named for the rivers in which they were first discovered: Ouachita River (G. ouachitensis); Sabine River (G. sabinensis); Pearl River (G. pearlensis). The other species are all named for various aspects of the topographic map like patterns and other markings, colors, and contours of the carapace, that are most apparent in the juveniles and young adults of these attractive turtles: G. flavimaculata, flavus = yellow, maculatus = spotted or blotched; G. geographica, geographica = geographic map like; G.  nigrinoda, niger = black, nodus = knot, node, or knob; G. oculifera, oculus = eye, fero = to bear (eye shape rings on the pleurals scutes); G. pseudogeographica, pseudo = false, geographica = geographic map like; G. pulchra, pulchra = beautiful; G. versa, vers = to change (probably referring to the contrasting head patterns compared to G. pseudogeographica).
+
+
+== Description ==
+
+Graptemys species superficially resemble many other species of aquatic turtles, including sliders (Trachemys) and cooters (Pseudemys).  However, they are distinguished by a keel that runs the length of the center of the carapace. In some southern species, the keel can result in vertebral spines, resulting in the map turtle's other common name — "sawback". They also typically grow to a smaller size at maturity. They are given the common name "map turtle" due to the map-like markings on the carapace. Map turtles are known for intricate head markings and strong sexual dimorphism with mature females twice the length and 10 times the mass of mature males.
+
+
+=== Feeding morphology ===
+Females of all map turtle species can be partitioned into three groups based on head (alveolar) width and corresponding ecology and phylogeny.
+
+Microcephalic females are narrow headed, sympatric with a broader headed species, and consume few mollusks.  Microcephalic species include yellow-blotched, black-knobbed, ringed, Ouachita, and Sabine map turtles.
+Mesocephalic females have moderately broad heads and tend to eat mostly mollusks along with softer bodied prey. Mesocephalic species include Cagle's, northern, false, Mississippi, and Texas map turtles.
+Megacephalic females have exceptionally broad heads, and feed almost exclusively on mollusks. Megacephalic females include Barbour's, Escambia, Pascagoula, Pearl River, and Alabama map turtles.Males do not fit neatly into the three groups describing head width, with differences in head width likely not influencing diet.
+Due to these differences in head size and jaw strength, females tend to eat much larger prey than the males such as snails, clams, and crayfish whereas the males eat insects and smaller crustaceans.: 237 p.    
+Including deadwood material inside of the Graptemys habitat then the chances of more Graptemys migrating or being born in that area is greater. The population can use a healthy habitat that can support a significant number of Graptemys and dead wood will help with this.
+
+
+== Distribution ==
+
+Map turtles are endemic to North America. The genus ranges from the Great Lakes region and St. Lawrence River of southern Quebec and Ontario, Canada, south to the Gulf of Mexico, and the Hudson River and Delaware River basins on the Atlantic coast, west to the eastern margins of the Great Plains. Most species occur in rivers, moving waters, or larger lakes. Eleven of the 14 species have relatively limited distributions, restricted to river basins draining into the Gulf of Mexico, in the US states of Texas, Louisiana, Mississippi, Alabama, southwest Georgia, and the Florida panhandle. Three species are more wide ranging, include the Ouachita Map Turtle (G. ouachitensis) and the False Map Turtle (G. pseudogeographica) which range extensively in the Mississippi River drainage and its tributaries including much of the mid west, with the latter also ranging west into east Texas. The Northern Map Turtle (G. geographica) is the most widespread species, occurring in both Atlantic and Gulf of Mexico river drainages, from southern Quebec, Canada, west to Minnesota and eastern Kansas, south to New Jersey and above (north) of the fall line in Georgia, Alabama, and extreme northern Louisiana.: 202–209 pp. 
+
+
+== Ecology and natural history ==
+
+
+=== Habitat ===
+Map turtles are predominantly lotic, living in moving water, such as rivers and larger creeks, streams, and bayous. The northern and wide-ranging Mississippi River species (G. geographica, G. pseudogeographica, G. ouachitensis) tend to inhabit more diverse habitats, including sloughs, oxbow lakes, and backwater areas of river bottoms, as well as lakes and occasionally even ponds and marshlands. Other species use these environments much less frequently, or as juveniles or during seasonal flooding, and a few species have never been reported from areas beyond the main channels of their respective river systems (e.g. G. gibbonsi, G. pearlensis, G. sabinensis). Several species will inhabit manmade reservoirs in their river systems, while other species are very uncommon in such impoundments (e.g. G. oculifera, G. versa), and still others are entirely absent from reservoirs (e. g. G. caglei). With few exceptions (G. barbouri, G. flavimaculata, G. nigrinoda), most species do not occur in tidally influenced waterways, estuaries, or brackish waters, which are occupied by their closest relative the diamondback terrapin (Malaclemys terrapin). The upstream distributional limits of many species are often associated with the level of sunlight penetration through the forest canopy. Larger, wider waterways allow sunlight to reach the surface, providing for the growth of aquatic vegetation and algae (food) and basking sites for Graptemys populations. Smaller streams in the shadow of forest canopies, or that receive brief patchy sunlight, are rarely inhabited by Graptemys.: 84–87, 255–360 pp. : 272–343 pp. 
+
+The ecology of many species of map turtles, particularly habitat use and diet, have been well studied. Specific habitat use often differs among males and females of the same species, as well as sympatric species sharing a river system, all inextricably linked to their diets in a somewhat complex example of  niche differentiation. Ten of the 14 Graptemys species share a river basin with another Graptemys species, and three species occur in regions of Alabama, and portions of the Mississippi River. Generally the mesocephalic and megacephalic females occupy deeper areas with stronger currents and hard-bottom, limestone sections of rivers, and males inhabit slower, shallower areas of the rivers nearer to the shore, largely correlated with their respective diets and prey distribution. Graptemys rarely walk on land or move between waterways. Most species are reluctant to bask on river banks and are seldom seen even on fallen trees with one end resting on the bank. Basking sites are most often fallen tree and deadwood emerging from water with no direct contact to the banks. Although the wide-ranging, northern species (G. geographica, G. pseudogeographica, G. ouachitensis) tend to be more flexible in their basking habits.: 84–87, 255–360 pp. : 272–343 pp. The natural meandering of rivers, riparian forest, and fallen trees and deadwood in the water are all key and vital elements to sustain most map turtle populations, particularly the Gulf Coast species. The outer bend in a river is typically the deeper side, with the stronger current of the main channel, eroding and cutting into the outer bank and falling trees of the riparian zone forest as it does. While the inside of the bend is shallower, with a slower current, dropping silt deposits and building beaches and sandbars. The meandering course maintains a diverse spectrum of water depths, temperatures, currents, soft and hardpan bottoms, as well as fallen trees and logs that get lodged in the bends. Beaches and sand bars are essential nesting sites. The presence of partially submerged deadwood and trees are critical, not only for basking, but for the growth of algae, bryozoans, sponges, snails, insects and their eggs larva that live in the growth, which are important food items for turtles.: 84–87, 255–360 pp. : 272–343 pp. 
+
+
+=== Courtship behavior ===
+Adult Graptemys males have greatly elongated claws on the front feet, which are used in courtship behavior.  The male faces the considerably larger female and "fans" her face, vibrating his foreclaws against her head to induce her to cooperate in mating.
+
+
+=== Longevity ===
+Complete and accurate longevity records for map turtles are lacking. A review of zoo records published in 1992 identified the maximum period of time that many species of Graptemys lived in captivity in North American zoos, ranging from eight to 35 years, including: Barbour's map turtle (G. barbouri) 31 years 8 months; false map turtle (G. pseudogeographica ssp.) 32 years and 6 months; Mississippi map turtle (G. pseudogeographica kohnii) 35 years 5 months. However, it is important to note that in every example these records involve turtles that were acquired by the zoos as adults from the wild, or of unknown origins and of undetermined ages. Therefore the records only reflect the period of time that an individual turtle was maintained at the institutions before it died, not the full lifespan of the individual.: 13 p.  Subsequently, the longevity of two female Barbour's Map Turtles (G. barbouri) of unknown ages and origin at the Columbus Zoo were reported at 37 and 43 years. Herpetologist Carl Ernst noted northern map turtles (G. geographica) and Alabama map turtles (G. pulchra) likely live well over 20 years in the wild,: 300 & 339 p.  and ringed map turtles (G. oculifera) are known to live at least 30 years in the wild. Based on records of other turtles in the Emydidae family, it is likely Graptemys longevity exceeds these records significantly, perhaps by decades.: 114 p. 
+
+
+== Conservation ==
+The most frequently cited and best-documented threats to map turtle and sawback populations involve modifications of the rivers and lakes they inhabit and their take for the pat trade.: 198 p. 
+
+The limited ranges and restricted habitats of most species make Graptemys particularly vulnerable to conservation issues. The destruction and fragmentation of habitat through the engineering of rivers and lakes, such as channelization, dams and impoundments, gravel and sand mining, pollution, clearing and development of riparian zones, and the removal of logs and deadwood from waterways are among the foremost conservation threats to map turtles. These activities degrade or destroy nesting sites (sandbars), prey species and prey habitat, and basking sites that are essential for thermoregulation and the turtles survival. The pet trade is another significant threat to the survival of map turtles. In the year in 2000 alone, 200,000 live Graptemys were exported from the USA, predominantly to Europe, and this does not take into account the domestic market.: 192–206 p. A variety of human activities such as bycatch in gillnetting and fyke nets, injuries form boat propellers, and "plinking", the practice of shooing turtles for target practice, or for the misinformed idea that they are significant competitors for game fish, all contribute to mortalities. Seemingly benign activities such as the regular use of sandbar beaches for recreation, swimming, and heavy boat traffic are known to cause turtles to abandon stretches of rivers and nesting sites. Some lesser threats include invasive species such as fire ants (Solenopsis invicta) which are known to prey on eggs and hatchlings. Invasive plants such as water hyacinth (Eichhornia crassipes), alligator weed (Alternanthera philoxeroides), congon grass (Imperata cylindrica), cocklebur (Xanthium stramarium), and the Chinese tallow tree (Triadica sebifera) are all known to degrade Graptemys habitat and nesting beaches. Hydrilla (Hydrilla verticillata) has been associated with steep declines of black-knobbed map turtles in some areas. Conversely, maps turtles are known to feed on some non-native species of clams (Corbicula) and mussels (Dreissena).: 210–214 p. The United States Federal Government list two species, the yellow-blotched map turtle (G. flavimaculata) and the ringed map turtle (G. oculifera) as threatened species. In Texas the state government list the Cagle's Map Turtle (G. caglei) as a threatened species. The state of Louisiana list the ringed map turtle (G. oculifera) as threatened and the Ouachita map turtle (G. ouachitensis) and Sabine Map Turtle (G. sabinensis) as vulnerable. The state of Mississippi list the yellow-blotched map turtle (G. flavimaculata) as threatened and the ringed map turtle (G. oculifera) and  black-knobbed map turtle (G. nigrinoda) as endangered. In Alabama, all six species of map turtles occurring in the state are classified as nongame species protected by the state. In Georgia the Barbour's map turtle (G. barbouri) is as threatened and the northern map turtle (G.  geographica) and Alabama map turtle (G. pulchra) are considered rare species ranked S1 and S3 respectively. In Florida Barbour's map turtle (G. barbouri) is state-designated as threatened. The Government of Canada list the Northern Map Turtle (G. geographica) is a species of special concern. Seven of the 14 Graptemys species are listed as either, near threatened, vulnerable, or endangered by the IUCN Red List as of 2021 As of 2021, all Graptemys are listed as Appendix III by CITES.
+
+
+== Pet trade ==
+Throughout the pet trade, the Mississippi map turtle, the northern map turtle, and Ouachita map turtle were bred and hatched out by the thousands in the 1970s. Various other turtles were available, but as the salmonellosis Four-inch Law was established, map turtles and others slowly decreased in popularity. Today, these same three still hold the title for most common among the pet trade. Other species being captive-bred more often include the Texas map turtle, Cagle's map turtle, and the black-knobbed map turtle. Some harder-to-find map turtles include the yellow-blotched map turtle and the Pearl River map turtle.

+Graptemys is a genus of freshwater turtles containing 14 species, commonly known as map turtles.  Graptemys are small to medium-sized turtles that are sexually dimorphic, with females attaining as much as twice the length and ten times the mass as males in some species. Depending on the species, adult males range from 7–16 cm (2.75–6.25 in), adult females 10–29.5 cm (4–11.62 in), and hatchlings 2.5–3.8 cm (1–1.5 in),: 202–209 p.  although some sources indicate female Barbour's map turtles (Graptemys barbouri) grow to 33 cm (13 in) in length.   Most species have a distinctive dark pigmented keel that is often notched or serrated running down the center of the carapace and serrated scutes on the rear margin.

+=== Fossil species ===
+An extinct species from the Suwannee River drainage in Florida, Graptemys kerneri belonging to the female megacephalic subclade, was described in 2011 from Pleistocene fossil records. 
+
+†Graptemys kerneri Ehret & Bourque, 2011
+
+
+== Etymology ==
+
+The generic name Graptemys is derived from two compounded Greek words, graptos, meaning inscribed or in writing, in reference to the patterns on the turtles shells, and emydos, meaning a freshwater turtle. The trivial names, or specific epithets, of four of the species in the genus are patronyms or eponyms, named in honor of prominent herpetologist, each of whom made significant contributions to studies on North American turtles: Thomas Barbour (G. barbouri); Fred Ray Cagle (G. caglei); Carl Henry Ernst (G. ernsti); J. Whitfield Gibbons (G. gibbonsi). One subspecies is named for the collector of the type specimen, Joseph Gustave Kohn (G. pseudogeographica kohnii). Three species are named for the rivers in which they were first discovered: Ouachita River (G. ouachitensis); Sabine River (G. sabinensis); Pearl River (G. pearlensis). The other species are all named for various aspects of the topographic map like patterns and other markings, colors, and contours of the carapace, that are most apparent in the juveniles and young adults of these attractive turtles: G. flavimaculata, flavus = yellow, maculatus = spotted or blotched; G. geographica, geographica = geographic map like; G.  nigrinoda, niger = black, nodus = knot, node, or knob; G. oculifera, oculus = eye, fero = to bear (eye shape rings on the pleurals scutes); G. pseudogeographica, pseudo = false, geographica = geographic map like; G. pulchra, pulchra = beautiful; G. versa, vers = to change (probably referring to the contrasting head patterns compared to G. pseudogeographica).
+
+
+== Description ==
+
+Graptemys species superficially resemble many other species of aquatic turtles, including sliders (Trachemys) and cooters (Pseudemys).  However, they are distinguished by a keel that runs the length of the center of the carapace. In some southern species, the keel can result in vertebral spines, resulting in the map turtle's other common name — "sawback". They also typically grow to a smaller size at maturity. They are given the common name "map turtle" due to the map-like markings on the carapace. Map turtles are known for intricate head markings and strong sexual dimorphism with mature females twice the length and 10 times the mass of mature males.
+
+
+=== Feeding morphology ===
+Females of all map turtle species can be partitioned into three groups based on head (alveolar) width and corresponding ecology and phylogeny.
+
+Microcephalic females are narrow headed, sympatric with a broader headed species, and consume few mollusks.  Microcephalic species include yellow-blotched, black-knobbed, ringed, Ouachita, and Sabine map turtles.
+Mesocephalic females have moderately broad heads and tend to eat mostly mollusks along with softer bodied prey. Mesocephalic species include Cagle's, northern, false, Mississippi, and Texas map turtles.
+Megacephalic females have exceptionally broad heads, and feed almost exclusively on mollusks. Megacephalic females include Barbour's, Escambia, Pascagoula, Pearl River, and Alabama map turtles.Males do not fit neatly into the three groups describing head width, with differences in head width likely not influencing diet.
+Due to these differences in head size and jaw strength, females tend to eat much larger prey than the males such as snails, clams, and crayfish whereas the males eat insects and smaller crustaceans.: 237 p.    
+Including deadwood material inside of the Graptemys habitat then the chances of more Graptemys migrating or being born in that area is greater. The population can use a healthy habitat that can support a significant number of Graptemys and dead wood will help with this.
+
+
+== Distribution ==
+
+Map turtles are endemic to North America. The genus ranges from the Great Lakes region and St. Lawrence River of southern Quebec and Ontario, Canada, south to the Gulf of Mexico, and the Hudson River and Delaware River basins on the Atlantic coast, west to the eastern margins of the Great Plains. Most species occur in rivers, moving waters, or larger lakes. Eleven of the 14 species have relatively limited distributions, restricted to river basins draining into the Gulf of Mexico, in the US states of Texas, Louisiana, Mississippi, Alabama, southwest Georgia, and the Florida panhandle. Three species are more wide ranging, include the Ouachita Map Turtle (G. ouachitensis) and the False Map Turtle (G. pseudogeographica) which range extensively in the Mississippi River drainage and its tributaries including much of the mid west, with the latter also ranging west into east Texas. The Northern Map Turtle (G. geographica) is the most widespread species, occurring in both Atlantic and Gulf of Mexico river drainages, from southern Quebec, Canada, west to Minnesota and eastern Kansas, south to New Jersey and above (north) of the fall line in Georgia, Alabama, and extreme northern Louisiana.: 202–209 pp. 
+
+
+== Ecology and natural history ==
+
+
+=== Habitat ===
+Map turtles are predominantly lotic, living in moving water, such as rivers and larger creeks, streams, and bayous. The northern and wide-ranging Mississippi River species (G. geographica, G. pseudogeographica, G. ouachitensis) tend to inhabit more diverse habitats, including sloughs, oxbow lakes, and backwater areas of river bottoms, as well as lakes and occasionally even ponds and marshlands. Other species use these environments much less frequently, or as juveniles or during seasonal flooding, and a few species have never been reported from areas beyond the main channels of their respective river systems (e.g. G. gibbonsi, G. pearlensis, G. sabinensis). Several species will inhabit manmade reservoirs in their river systems, while other species are very uncommon in such impoundments (e.g. G. oculifera, G. versa), and still others are entirely absent from reservoirs (e. g. G. caglei). With few exceptions (G. barbouri, G. flavimaculata, G. nigrinoda), most species do not occur in tidally influenced waterways, estuaries, or brackish waters, which are occupied by their closest relative the diamondback terrapin (Malaclemys terrapin). The upstream distributional limits of many species are often associated with the level of sunlight penetration through the forest canopy. Larger, wider waterways allow sunlight to reach the surface, providing for the growth of aquatic vegetation and algae (food) and basking sites for Graptemys populations. Smaller streams in the shadow of forest canopies, or that receive brief patchy sunlight, are rarely inhabited by Graptemys.: 84–87, 255–360 pp. : 272–343 pp. 
+
+The ecology of many species of map turtles, particularly habitat use and diet, have been well studied. Specific habitat use often differs among males and females of the same species, as well as sympatric species sharing a river system, all inextricably linked to their diets in a somewhat complex example of  niche differentiation. Ten of the 14 Graptemys species share a river basin with another Graptemys species, and three species occur in regions of Alabama, and portions of the Mississippi River. Generally the mesocephalic and megacephalic females occupy deeper areas with stronger currents and hard-bottom, limestone sections of rivers, and males inhabit slower, shallower areas of the rivers nearer to the shore, largely correlated with their respective diets and prey distribution. Graptemys rarely walk on land or move between waterways. Most species are reluctant to bask on river banks and are seldom seen even on fallen trees with one end resting on the bank. Basking sites are most often fallen tree and deadwood emerging from water with no direct contact to the banks. Although the wide-ranging, northern species (G. geographica, G. pseudogeographica, G. ouachitensis) tend to be more flexible in their basking habits.: 84–87, 255–360 pp. : 272–343 pp. The natural meandering of rivers, riparian forest, and fallen trees and deadwood in the water are all key and vital elements to sustain most map turtle populations, particularly the Gulf Coast species. The outer bend in a river is typically the deeper side, with the stronger current of the main channel, eroding and cutting into the outer bank and falling trees of the riparian zone forest as it does. While the inside of the bend is shallower, with a slower current, dropping silt deposits and building beaches and sandbars. The meandering course maintains a diverse spectrum of water depths, temperatures, currents, soft and hardpan bottoms, as well as fallen trees and logs that get lodged in the bends. Beaches and sand bars are essential nesting sites. The presence of partially submerged deadwood and trees are critical, not only for basking, but for the growth of algae, bryozoans, sponges, snails, insects and their eggs larva that live in the growth, which are important food items for turtles.: 84–87, 255–360 pp. : 272–343 pp. 
+
+
+=== Courtship behavior ===
+Adult Graptemys males have greatly elongated claws on the front feet, which are used in courtship behavior.  The male faces the considerably larger female and "fans" her face, vibrating his foreclaws against her head to induce her to cooperate in mating.
+
+
+=== Longevity ===
+Complete and accurate longevity records for map turtles are lacking. A review of zoo records published in 1992 identified the maximum period of time that many species of Graptemys lived in captivity in North American zoos, ranging from eight to 35 years, including: Barbour's map turtle (G. barbouri) 31 years 8 months; false map turtle (G. pseudogeographica ssp.) 32 years and 6 months; Mississippi map turtle (G. pseudogeographica kohnii) 35 years 5 months. However, it is important to note that in every example these records involve turtles that were acquired by the zoos as adults from the wild, or of unknown origins and of undetermined ages. Therefore the records only reflect the period of time that an individual turtle was maintained at the institutions before it died, not the full lifespan of the individual.: 13 p.  Subsequently, the longevity of two female Barbour's Map Turtles (G. barbouri) of unknown ages and origin at the Columbus Zoo were reported at 37 and 43 years. Herpetologist Carl Ernst noted northern map turtles (G. geographica) and Alabama map turtles (G. pulchra) likely live well over 20 years in the wild,: 300 & 339 p.  and ringed map turtles (G. oculifera) are known to live at least 30 years in the wild. Based on records of other turtles in the Emydidae family, it is likely Graptemys longevity exceeds these records significantly, perhaps by decades.: 114 p. 
+
+
+== Conservation ==
+The most frequently cited and best-documented threats to map turtle and sawback populations involve modifications of the rivers and lakes they inhabit and their take for the pat trade.: 198 p. 
+
+The limited ranges and restricted habitats of most species make Graptemys particularly vulnerable to conservation issues. The destruction and fragmentation of habitat through the engineering of rivers and lakes, such as channelization, dams and impoundments, gravel and sand mining, pollution, clearing and development of riparian zones, and the removal of logs and deadwood from waterways are among the foremost conservation threats to map turtles. These activities degrade or destroy nesting sites (sandbars), prey species and prey habitat, and basking sites that are essential for thermoregulation and the turtles survival. The pet trade is another significant threat to the survival of map turtles. In the year in 2000 alone, 200,000 live Graptemys were exported from the USA, predominantly to Europe, and this does not take into account the domestic market.: 192–206 p. A variety of human activities such as bycatch in gillnetting and fyke nets, injuries form boat propellers, and "plinking", the practice of shooing turtles for target practice, or for the misinformed idea that they are significant competitors for game fish, all contribute to mortalities. Seemingly benign activities such as the regular use of sandbar beaches for recreation, swimming, and heavy boat traffic are known to cause turtles to abandon stretches of rivers and nesting sites. Some lesser threats include invasive species such as fire ants (Solenopsis invicta) which are known to prey on eggs and hatchlings. Invasive plants such as water hyacinth (Eichhornia crassipes), alligator weed (Alternanthera philoxeroides), congon grass (Imperata cylindrica), cocklebur (Xanthium stramarium), and the Chinese tallow tree (Triadica sebifera) are all known to degrade Graptemys habitat and nesting beaches. Hydrilla (Hydrilla verticillata) has been associated with steep declines of black-knobbed map turtles in some areas. Conversely, maps turtles are known to feed on some non-native species of clams (Corbicula) and mussels (Dreissena).: 210–214 p. The United States Federal Government list two species, the yellow-blotched map turtle (G. flavimaculata) and the ringed map turtle (G. oculifera) as threatened species. In Texas the state government list the Cagle's Map Turtle (G. caglei) as a threatened species. The state of Louisiana list the ringed map turtle (G. oculifera) as threatened and the Ouachita map turtle (G. ouachitensis) and Sabine Map Turtle (G. sabinensis) as vulnerable. The state of Mississippi list the yellow-blotched map turtle (G. flavimaculata) as threatened and the ringed map turtle (G. oculifera) and  black-knobbed map turtle (G. nigrinoda) as endangered. In Alabama, all six species of map turtles occurring in the state are classified as nongame species protected by the state. In Georgia the Barbour's map turtle (G. barbouri) is as threatened and the northern map turtle (G.  geographica) and Alabama map turtle (G. pulchra) are considered rare species ranked S1 and S3 respectively. In Florida Barbour's map turtle (G. barbouri) is state-designated as threatened. The Government of Canada list the Northern Map Turtle (G. geographica) is a species of special concern. Seven of the 14 Graptemys species are listed as either, near threatened, vulnerable, or endangered by the IUCN Red List as of 2021 As of 2021, all Graptemys are listed as Appendix III by CITES.
+
+
+== Pet trade ==
+Throughout the pet trade, the Mississippi map turtle, the northern map turtle, and Ouachita map turtle were bred and hatched out by the thousands in the 1970s. Various other turtles were available, but as the salmonellosis Four-inch Law was established, map turtles and others slowly decreased in popularity. Today, these same three still hold the title for most common among the pet trade. Other species being captive-bred more often include the Texas map turtle, Cagle's map turtle, and the black-knobbed map turtle. Some harder-to-find map turtles include the yellow-blotched map turtle and the Pearl River map turtle.

+The short-tailed parrot (Graydidascalus brachyurus) is the only species of the genus Graydidascalus. It is found along both banks of the Amazon river and other major Amazonian rivers in Brazil, Colombia, Bolivia, Ecuador and Peru. As suggested by its range, it is associated with the specific forest and woodland types growing near major rivers, although it also extends into the coastal deltas of French Guiana and Amapá, Brazil.
+The closest relative is the yellow-faced parrot (Alipiopsitta xanthops) and the members of the genus Pionus.
+
+
+== Description ==
+It has a total length of about 24 cm (9+1⁄2 in). It is overall green with a large dark bill (large even for a parrot) and, as suggested by its name, a very short tail. Adults show a small maroon-red spot on the shoulder and at the base of the outer tail-feathers, but typically neither are easy to see.

+The red-crowned crane (Grus japonensis), also called the Manchurian crane or Japanese crane (traditional Chinese: 丹頂鶴; simplified Chinese: 丹顶鹤; pinyin: dāndǐng hè; Japanese: 丹頂鶴 or タンチョウヅル; Korean: 두루미; the Chinese character '丹' means 'red', '頂/顶' means 'crown' and '鶴/鹤' means 'crane'), is a large East Asian crane among the rarest cranes in the world. In some parts of its range, it is known as a symbol of luck, longevity, and fidelity.
+
+
+== Description ==
+
+Adult red-crowned cranes are named for a patch of red bare skin on the crown, which becomes brighter during the mating season. Overall, they are snow white in color with black on the wing secondaries, which can appear almost like a black tail when the birds are standing, but the real tail feathers are actually white. Males are black on the cheeks, throat, and neck, while females are pearly gray in these spots. The bill is olive green to a greenish horn, the legs are slate to grayish black, and the iris is dark brown.Juveniles are a combination of white, partly tawny, cinnamon brown, and rusty or grayish. The neck collar is grayish to coffee brown, the secondaries are dull black and brown, and the crown and forehead are covered with gray and tawny feathers. The primaries are white, tipped with black, as are the upper primary coverts. The legs and bill are similar to those of adults but lighter in color.
+This species is among the largest and heaviest cranes, typically measuring about 150 to 158 cm (4 ft 11 in to 5 ft 2 in) tall and 101.2–150 cm (3 ft 4 in – 4 ft 11 in) in length (from bill to tail tip). Across the large wingspan, the red-crowned crane measures 220–250 cm (7 ft 3 in – 8 ft 2 in). Typical body weight can range from 4.8 to 10.5 kg (11 to 23 lb), with males being slightly larger and heavier than females and weight ranging higher just prior to migration. On average, it is the heaviest crane species, although both the sarus and wattled crane can grow taller and exceed this species in linear measurements.On average, adult males from Hokkaidō weighed around 8.2 kg (18 lb) and adult females there averaged around 7.3 kg (16 lb), while a Russian study found males averaged 10 kg (22 lb) and females averaged 8.6 kg (19 lb); in some cases, females could outweigh their mates despite the males' slightly larger average body weight. Another study found the average weight of the species to be 8.9 kg (20 lb). The maximum known weight of the red-crowned crane is 15 kg (33 lb). Among standard measurements, the wing chord measures 50.2–74 cm (19.8–29.1 in), the exposed culmen measures 13.5–17.7 cm (5.3–7.0 in), tail length is 21.5–30 cm (8.5–11.8 in), and the tarsus measures 23.7–31.9 cm (9.3–12.6 in).
+
+
+== Range and habitat ==
+
+In the spring and summer, the migratory populations of the red-crowned crane breed in Siberia (eastern Russia), north-eastern China and occasionally in north-eastern Mongolia (i.e., Mongol Daguur Strictly Protected Area). The breeding range centers in Lake Khanka, on the border of China and Russia. Later, in the fall, they migrate in flocks to the Korean Peninsula and east-central China to spend the winter. Vagrants have also been recorded in Taiwan. In addition to the migratory populations, a resident population is found in eastern Hokkaidō, Japan. This species nests in wetlands, marshes and rivers. In the wintering range, their habitat consists mainly of paddy fields, grassy tidal flats, and mudflats. In the flats, the birds feed on aquatic invertebrates, and, in cold, snowy conditions, the birds switch to mainly living on rice gleanings from the paddy fields.
+
+
+== Ecology and behaviour ==
+
+
+=== Diet ===
+
+Red-crowned cranes have a highly omnivorous diet, though the dietary preferences have not been fully studied. They eat rice, parsley, carrots, redbuds, acorns, buckwheat, and a variety of water plants. The animal matter in their diet consists of fish, including carp and goldfish, amphibians, especially salamanders, snails, crabs, dragonflies, small reptiles, shrimp and small birds.  The daily food requirement of adult red-crowned cranes is 750 g.They seem to prefer a carnivorous diet, although rice is now essential to survival for wintering birds in Japan and grass seeds are another important food source. While all cranes are omnivorous, per Johnsgard, the two most common crane species today (the sandhill and common cranes) are among the most herbivorous species while the two rarest species (the red-crowned and whooping cranes) are perhaps the most carnivorous species. When feeding on plants, red-crowned cranes exhibit a preference for plants with a high content of crude protein and low content of crude fiber. In Hokkaido, fish such as Tribolodon, Pungitius, Sculpin and flatfish was major prey of adults, while chicks mostly feed on various insects. In Zhalong Nature Reserve, small fish less than 10cm, such as common carps, pond loach, and Chinese sleeper was mainly taken as well as aquatic invertebreas like pond snails, dragonflys, water beetles and large amount of plant matter. Elsewhere, mudflat crabs are locally important food source in Yellow River Delta.They typically forage by keeping their heads close to the ground, jabbing their beaks into mud when they encounter something edible. When capturing fish or other slippery prey, they strike rapidly by extending their necks outward, a feeding style similar to that of the heron. Although animal prey can be swallowed whole, red-crowned cranes more often tear up large prey by grasping with their beaks and shaking it vigorously, eating pieces as they fall apart. Most foraging occurs in wet grasslands, cultivated fields, shallow rivers, or on the shores of lakes.
+
+
+=== Migration ===
+
+The population of red-crowned cranes in Japan is mostly non-migratory, with the race in Hokkaidō moving only 150 km (93 mi) to its wintering grounds. Only the mainland population experiences a long-distance migration. They leave their wintering grounds in spring by February and are established on territories by April. In fall, they leave their breeding territories in October and November, with the migration fully over by mid-December.
+
+
+=== Sociality ===
+Flock sizes are affected by the small numbers of the red-crowned crane, and given their largely carnivorous diet, some feeding dispersal is needed in natural conditions. Wintering cranes have been observed foraging, variously, in family groups, pairs, and singly, although all roosting is in larger groups (up to 80 individuals) with unrelated cranes. By the early spring, pairs begin to spend more time together, with nonbreeding birds and juveniles dispersing separately. Even while not nesting, red-crowned cranes tend to be aggressive towards conspecifics and maintain a minimum distance of 2 to 3 m (6.6 to 9.8 ft) to keep out of pecking range of other cranes while roosting nocturnally during winter. In circumstances where a crane violates these boundaries, it may be violently attacked.
+
+
+=== Breeding ===
+
+The red-crowned crane is monogamous and long-lived, with stable pair-bonding both within and between years, and believed to mate for life. The breeding maturity is thought to be reached at 3–4 years of age. All mating and egg-laying are largely restricted to April and early May. A red-crowned crane pair duets in various situations, helping to establish the formation and maintenance of the pair bond, as well as territorial advertisement and agonistic signaling. Both males and females may start a duet with the production of a start call, but the main part of the duet always began with a long male call. The pair moves rhythmically until they are standing close, throwing their heads back and letting out a fluting call in unison, often triggering other pairs to start duetting, as well. As it occurs year-round, the social implications of dancing are complex in meaning. However, dancing behavior is generally thought to show excitement in the species. Also, the performance of duet displays increased the probability of staying in a favorable area, supporting the hypothesis that duet displays function as a signal of joint resource defense in the flock.
+
+Pairs are territorial during the breeding season. Nesting territories range from 1 to 7 km2 (0.39 to 2.70 sq mi) and are often the same year after year. Most nesting territories are characterized by flat terrain, access to wetland habitat, and tall grasses. Nest sites are selected by females, but built by both sexes and are frequently in a small clearing made by the cranes, either on wet ground or shallow water over waters no more than 20 to 50 cm (7.9 to 19.7 in) deep. Sometimes, nests are built on the frozen surface of water, as frigid temperatures may persist well into nesting season. Nest building takes about a week. A majority of nests contains two eggs, though one to three have been recorded. 
+Both sexes incubate the eggs for at least 30 days. They also both feed the young when they hatch. Staying in the nest for the first few weeks, the young start to follow their parents as they forage in marshes by around 3 months of age. New hatchlings weigh about 150 g (5.3 oz) and are covered in yellow natal down for two weeks. By early fall, about 95 days after hatching, the young are fledged and are assured fliers by migration time. Although they can fly well, crane young remain together with their parents for around 9 months. Young cranes maintain a higher-pitched voice that may serve to distinguish them from outwardly similar mature birds, this stage lasting until the leave parental care. The average adult lifespan is around 30 to 40 years, with some specimens living to 75 years of age in captivity. It is one of the longest-living species of bird.
+
+
+=== Interspecies interactions ===
+The red-crowned crane is a big-sized bird and there are no natural predators within their wintering ground. With their height averaging 1.5 m (5 ft), their large size deters most predators. As a result, red-crowned cranes often react indifferently to the presence of other birds such as small raptors; with harriers, falcons, owls, and usually buzzards being allowed to hunt small prey near a crane nest without any of these parties harassing each other. However, birds more likely to be egg or nest predators, such as corvids, some buzzards, and various eagles, are treated aggressively and are threatened until they leave the crane's territory. Mammalian carnivores, including red foxes, badgers, raccoon dogs, martens, and domestic dogs which pose a threat to eggs and chicks, are attacked immediately, with the parent cranes attempting to jab them in the flanks until the predators leave the vicinitly. These small predators do not present any danger to chicks in the presence of adults and are chased away by the crane without difficulty. Larger predators such as gray wolves and large dogs can be repelled by aggressive crane pairs.Occasionally, losses at the nest occur to some of the above predators. Introduced American mink on Hokkaidō are one of the most successful predators of eggs and nestlings. Also, immature and unwary subadult or even adult cranes may be ambushed killed by red foxes in Japan and leopard cats in South Korea, though this is rare reports, especially with adults. More often, these birds can easily defend themselves by using sharp beak or just fly away from danger.Smaller white-naped cranes often nest near red-crowned cranes, but competition between these species for food in a common nesting area is lessened due to the greater portion of vegetation in the white-naped crane's diet. In cases where interactions turn aggressive between white-naped and red-crowned cranes, red-crowned cranes are dominant, as expected due to their considerably larger size. As reported researchers trying to band or examine the cranes or their nest, this powerful species is considered mildly hazardous and prone to respond quickly with considerable aggression to being approached or handled by humans and are able to inflict painful injuries using both its kicking feet and dagger-like beak.
+
+
+== Status ==
+
+The population of red-crowned cranes is split into a migratory continental population in Korea, China, Mongolia, and Russia, and a resident Japanese population in Hokkaidō. The estimated total population of the species is only 1,830 in the wild, including about 950 birds in the resident Japanese population. Of the migratory populations, about 400-500 winter in China (mainly at the Yellow River delta and Yancheng Coastal Wetlands), and the remaining 1000-1050 winter in Korea. It received endangered status on 2 June 1970.
+The National Aviary in Pittsburgh, Pennsylvania, ran a program where U.S. zoos donated eggs which were flown to Russia and raised in the Khinganski Nature Reserve and released into the wild. This program sent 150 eggs between 1995 and 2005.  The program has been put on hold to concentrate on different crane conservation programs in Russia, such as education and fire suppression. Several hundred red-crowned cranes are kept in zoos around the world. Assuredly, the international efforts of Russia, China, Japan, and Korea are needed to keep the species from extinction. The most pressing threat is habitat destruction, with a general lack of remaining pristine wetland habitats for the species to nest. In Japan, little proper nesting habitat remains and the local breeding population is close to the saturation point.In South Korea, it has been designated natural monument 202 and a first-class endangered species.
+
+
+== Culture ==
+
+
+=== China ===
+
+In China, the red-crowned crane is often featured in myths and legends. In Taoism, the red-crowned crane is a symbol of longevity and immortality. In art and literature, immortals are often depicted riding on cranes. A mortal who attains immortality is similarly carried off by a crane. Reflecting this association, red-crowned cranes are called xian he (traditional Chinese: 仙鶴; simplified Chinese: 仙鹤; pinyin: xiānhè; "fairy crane" or "crane of the immortals""). The red-crowned crane is also a symbol of nobility. Depictions of the crane have been found in Shang Dynasty tombs and Zhou Dynasty ceremonial bronzeware. A common theme in later Chinese art is the reclusive scholar who cultivates bamboo and keeps cranes. Some literati even reared cranes and trained them to dance to guqin music.
+The Ming and Qing Dynasties endowed the Red Crowned Crane with the cultural connotation of loyalty, uprightness and noble morality. Red Crowned Crane is embroidered on the clothes of a civil servant. It is listed as an important symbol next only to the Loong and Fenghuang used by the royal family. Therefore, people also regard the crane as a symbol of a high official.
+
+The image of Red Crowned Crane generally appears in Chinese cultural relics and works of art.
+		
+		
+		
+		
+Because of its importance in Chinese culture, the red-crowned crane was selected by the National Forestry Bureau of the People's Republic of China as a candidate for the title of national animal of China. This decision was deferred due to the red-crowned crane's Latin name translation as "Japanese crane".Robert Kuok's Kerry/Kuok Group also uses the red-crowned crane as its logo for operations in Hong Kong, Singapore, PR China, and overseas.
+
+
+=== Japan ===
+
+In Japan, this crane is known as the tanchōzuru and is said to live for 1,000 years. A pair of red-crowned cranes was used in the design for the Series D 1000-yen note (reverse side). In the Ainu language, the red-crowned crane is known as sarurun kamuy or "marsh kamuy". At Tsurui, they are one of the 100 Soundscapes of Japan. Cranes are said to grant favours in return for acts of sacrifice, as in Tsuru no Ongaeshi ("crane's return of a favor").
+Given its reputation, Jerry Huff, an American branding expert, recommended it as the international logo of Japan Airlines, after seeing a representation of it in a gallery of samurai crests. Huff wrote "I had faith that it was the perfect symbol for Japan Air Lines. I found that the crane myth was all positive—it mates for life (loyalty), and flies high for miles without tiring (strength).”
+
+
+=== Korea ===
+
+In Korea, the red-crowned crane is called durumi or hak and it is considered a symbol of longevity, purity, and peace. Korean seonbis regarded the bird as an icon of their constancy. The red-crowned crane is depicted on the South Korean 500 won coin and is the symbol of Incheon.

+The Eurasian griffon vulture (Gyps fulvus) is a large Old World vulture in the bird of prey family Accipitridae. It may also be known as the Griffon vulture, though it may be used for the genus as a whole. It is not to be confused with Rüppell's griffon vulture (Gyps rueppellii). It is closely related to the white-backed vulture (Gyps africanus).
+
+
+== Description ==
+The griffon vulture is 93–122 cm (37–48 in) long with a 2.3–2.8 m (7.5–9.2 ft) wingspan. In the nominate race the males weigh 6.2 to 10.5 kg (14 to 23 lb) and females typically weigh 6.5 to 10.5 kg (14 to 23 lb), while in the Indian subspecies (G. f. fulvescens), the vultures average 7.1 kg (16 lb). Extreme adult weights have been reported from 4.5 to 15 kg (9.9 to 33.1 lb), the latter likely a weight attained in captivity. Hatched naked, it is a typical Old World vulture in appearance, with a very white head, very broad wings and short tail feathers. It has a white neck ruff and yellow bill. The buff body and wing coverts contrast with the dark flight feathers.
+
+
+== Distribution and habitat ==
+
+In Italy, the species managed to survive only in the island of Sardinia, but a few attempts at reintroducing the griffon in the peninsula have been recently made, too. As a result, several specimens have been spotted again in August 2006 on the Gran Sasso massif (central Italy). Populations in Italy are thought to be undergoing a vigorous increase, thanks to reintroduction schemes in neighbouring countries taking effect, and a ban on hunting the species.
+In Croatia, a colony of griffon vultures can be found near the town of Beli on the island of Cres. There they breed at lower elevations, with some nests just 10 m (33 ft) above sea level. Therefore, contact with people is common. The population makes frequent incursions in the Slovenian territory, especially in the mountain Stol above Kobarid. The bird is protected in an area called Kuntrep on the Croatian island of Krk
+In Ireland, the first record of a griffon vulture occurred in 1843 in Cork. More recently, in 2000 a vulture took up residence on the Channel Island of Guernsey.In Cyprus, there is an unsustainable colony of fewer than 30 birds (2016) at Episkopi, in the south of the island.In Israel and the occupied territories, colonies of griffon vultures can be found in northern Israel and in the Golan Heights, where a large colony breeds in the Carmel Mountains, the Negev desert and especially at Gamla, where reintroduction projects are being carried out at breeding centres in the Carmel and Negev.
+In Greece, there are nearly 1000 birds. The majority of griffon vulture population in Greece resides in Crete, which hosts the largest insular population of the species in the world. On Crete they can be found in most mountainous areas, sometimes in groups of up to 20.Griffon vultures have been reintroduced successfully into the Massif Central in France; about 500 are now found there. Griffon vultures are regularly spotted over the Millau bridge, and since 2015 also in the Cantal Mountains.
+
+In Belgium and the Netherlands, around 100 birds were present in the summer of 2007. These were vagrants from the Pyrenees population (see below).
+In Germany, the species died out in the mid-18th century. Some 200 vagrant birds, probably from the Pyrenees, were sighted in 2006, and several dozen of the vagrants sighted in Belgium the following year crossed into Germany in search for food. There are plans to reintroduce the species in the Alps. In September 2008, pieces of a griffon vulture bone, about 35,000 years old, were excavated from Hohle Fels cave in southern Germany, which are believed to form a flute.In Serbia, there are around 60–65 pairs of griffon vultures in the western parts of the country, around Zlatar mountain and also 35 birds in the canyon of the Trešnjica river. They are under legal protection from hunting.
+
+In Austria, there is a remnant population around Salzburg Zoo, and vagrants from the Balkans are often seen.
+In Spain and France, in 2008, there were 25,000 birds, from a low of a few thousand around 1980. Spain has the biggest colony of Griffon vultures in all Europe. It is located at Hoces del Río Duratón Natural Park (Province of Segovia).
+In Portugal a few hundred pairs of griffons nest, but their distribution is strongly asymmetric. The main areas of reproduction are located in the northeast (Douro International), which is home to more than half of the Portuguese population. Though permanently resident in the interior of the country, the griffon vulture often ventures west when the breeding season is over and can occasionally reach the Tagus Estuary and Cape St. Vincent.
+The Pyrenees population has apparently been affected by an EC ruling that due to danger of BSE transmission, no carcasses must be left on the fields for the time being. This has critically lowered food availability, and consequently, carrying capacity. Although the griffon vulture does not normally attack larger living prey, there are reports of Spanish griffon vultures killing weak, young or unhealthy living animals as they do not find enough carrion to eat. In May 2013, a 52-year-old woman who was hiking in the Pyrenees and had fallen off a cliff to her death was eaten by griffon vultures before rescue workers were able to recover her body, leaving only her clothes and a few of her bones. Due to her being the first human to be documented being eaten by griffon vultures, the story brought worldwide attention to the griffon vulture problems in Southern Europe.
+In Armenia there are 46-54 pairs according to last estimation of population; the trend demonstrates slight increasing.
+In Russia, nests on the northern slopes of the Greater Caucasus.
+
+
+== Behaviour and ecology ==
+
+Like other vultures, it is a scavenger, feeding mostly from carcasses of dead animals which it finds by soaring over open areas, often moving in flocks. It establishes nesting colonies in cliffs that are undisturbed by humans while coverage of open areas and availability of dead animals within dozens of kilometres of these cliffs is high. It grunts and hisses at roosts or when feeding on carrion.
+The maximum recorded lifespan of the griffon vulture is 41.4 years for an individual in captivity.It breeds on crags in mountains in southern Europe, north Africa, and Asia, laying one egg. Griffon vultures may form loose colonies. The population is mostly resident. Juveniles and immature individuals may migrate far or embark on long-distance movements. Density Dependence in this colonial species has been shown to affect annual reproductive success with eyries in protected location (caves, potholes and sheltered ledges) producing more fledglings, and used preferentially, than low-quality eyries (exposed ledges and open crevices), which were only used when the number of breeding individuals increased.
+
+
+=== Physiology ===
+Griffon vultures have been used as model organisms for the study of soaring and thermoregulation. The energy costs of level flight tend to be high, prompting alternatives to flapping in larger birds. Vultures in particular utilize more efficient flying methods such as soaring. Compared to other birds, which elevate their metabolic rate to upwards of 16 times their basal metabolic rate in flight, soaring griffon vultures expend about 1.43 times their basal metabolic rate in flight. Griffon vultures are also efficient flyers in their ability to return to a resting heart rate after flight within ten minutes.As large scavengers, griffon vultures have not been observed to seek shelter for thermoregulation. Vultures use their bald heads as a means to thermoregulate in both extreme cold and hot temperatures. Changes in posture can increase bare skin exposure from 7% to 32%. This change allows for the more than doubling of convective heat loss in still air. Griffon vultures have also been found to tolerate increased body temperatures as a response to high ambient temperatures. By allowing their internal body temperature to change independently of their metabolic rate, griffon vultures minimize their loss of water and energy in thermoregulating. One study in particular (Bahat 1995) found that these adaptations have allowed the Griffon vulture to have one of the widest thermal neutral zones of any bird.
+
+
+=== Intraspecific competition ===
+In respect to varying age ranges, the griffon vultures evidently show no difference in feeding rates. Inevitably, as resource availability increases, feeding rates tend to follow the same pattern. Upon studying the reintroduction of this species and its impact on the intraspecific competition, old adults are more inclined to display aggressive behavior and signs of dominance in comparison to the other age ranges. In terms of comparing the male and female sexes, there are no observed differences in competitive behaviors. Lastly, the reintroduced individuals of the species and the wild-bred do not differ in dominance or feeding rate despite the differences in upbringing.
+
+
+== Threats ==
+The main cause of the rapid decline in the griffon vulture population is the consumption of poisoned baits set out by people. Wildlife conservation efforts have attempted to increase awareness of the lethal consequences of using illegally poisoned baits through education about the issue.

+The Gila monster (Heloderma suspectum,  HEE-lə) is a species of venomous lizard native to the Southwestern United States and the northwestern Mexican state of Sonora. It is a heavy, typically slow-moving reptile, up to 56 centimetres (22 in) long, and it is the only venomous lizard native to the United States. Its venomous close relatives, the four beaded lizards (all former subspecies of Heloderma horridum) inhabit Mexico and Guatemala. The Gila monster is sluggish in nature, so it is not generally dangerous and very rarely poses a real threat to humans. However, it has a fearsome reputation and is sometimes killed in spite of the species being protected by state law in Arizona.
+
+
+== History ==
+
+The name "Gila" refers to the Gila River Basin in the U.S. states of Arizona and New Mexico, where the Gila monster was once plentiful. Heloderma means "studded skin", from the Ancient Greek words helos (ἧλος), "the head of a nail or stud", and derma (δέρμα), "skin". Suspectum comes from the describer, paleontologist Edward Drinker Cope. At first, this new specimen of Heloderma was misidentified and considered to be a northern variation of the beaded lizard already known to live in Mexico. He suspected that the lizard might be venomous due to the grooves in the teeth.
+
+The Gila monster is the largest extant lizard species native to North America north of the Mexican border. Its snout-to-vent length ranges from 26 to 36 cm (10 to 14 in). The tail is about 20% of the body size, and the largest specimens may reach 51 to 56 cm (20 to 22 in) in total length. Body mass is typically in the range of 550 to 800 g (1.21 to 1.76 lb). They appear strong in their body structure with a stout snout, massive head, and "little"-appearing eyes, which can be protected by a nictitating membrane.The Gila monster has four close living relatives, all of which are beaded lizards. There are three species in Mexico: Heloderma exasperatum, Heloderma horridum and Heloderma alvarezi, as well as another species in Guatemala: Heloderma charlesbogerti.The evolutionary history of the Helodermatidae may be traced back to the Cretaceous period (145 to 166 million years ago), when Gobiderma pulchrum and Estesia mongolensis were present. The genus Heloderma has existed since the Miocene, when H. texana lived. Fragments of osteoderms from the Gila monster have been found in Late Pleistocene (10,000 to 8,000 years ago) deposits near Las Vegas, Nevada. Because the helodermatids have remained relatively unchanged morphologically, they are occasionally regarded as living fossils. Although the Gila monster appears closely related to the monitor lizards (varanids) of Africa, Asia, and Australia, their wide geographical separation and distinct features indicate that Heloderma is better placed in a separate family.
+
+
+== Skin ==
+
+The scales of the head, back, and tail contain little pearl-shaped bones (osteoderms) similar to those found in the beaded lizards from further south. The scales of the belly are free from osteoderms. Female Gila monsters go through a total shed lasting about 2 weeks before depositing their eggs. The dorsal part is often shed in one large piece. Adult males normally shed in smaller segments in August. The young seem to be in constant shed. Adults have more or less yellow to pink colors on a black surface. Hatchlings have a uniform, simple, and less colorful pattern. This drastically changes within the first 6 months of their lives. Hatchlings from the northern area of the species' distribution have a tendency to retain most of their juvenile pattern.
+
+The heads of males are very often larger and more triangular-shaped than in females. The length of the tail of the two sexes is statistically very similar, so it does not help in differentiation of the sexes. Individuals with stout tail ends occur in both nature and under human breeding.
+
+
+== Distribution and habitat ==
+
+The Gila monster is found in the Southwestern United States and Mexico, a range including Sonora, Arizona, parts of California, Nevada, Utah, and New Mexico. No records have been given from Baja California. They inhabit scrubland, succulent desert, and oak woodland, seeking shelter in burrows, thickets, and under rocks in locations with a favorable microclimate and adequate humidity. Gila monsters depend on water resources and can be observed in puddles of water after a summer rain. They avoid living in open areas, such as flats and open grasslands.

+== Ecology ==
+
+Gila monsters spend 90% of their lifetime underground in burrows or rocky shelters. They are active in the morning during the dry season (spring and early summer). The lizards move to different shelters every 4–5 days up to the beginning of the summer season. By doing so, they optimize for a suitable microhabitat. Later in the summer, they may be active on warm nights or after a thunderstorm. They maintain a surface body temperature of about 30 °C (86 °F). Close to 37 °C (99 °F), they are able to decrease their body temperature by up to 2 °C (3.6 °F) by an activated, limited evaporation via the cloaca. One study investigating a population of Gila monsters in southwestern Utah noted that the lizard's activity peaked from late April to mid June. The average distance traveled during their bouts of activity was 210 metres (690 ft), but on occasion some lizards would travel distances greater than 1 kilometre (0.62 mi). During the Gila monster's active season of approximately 90 days, only ten days were spent active. Gila monsters are slow sprinters, but they have relatively high endurance and maximal aerobic capacity (VO2 max) compared to other lizards. They are preyed upon by coyotes, badgers and raptors. Hatchlings are preyed on by snakes, such as kingsnakes (Lampropeltis sp.).
+
+
+== Diet ==
+The Gila monster's diet consists of a variety of food items – small mammals (such as young rabbits, hares, mice, ground squirrels, and other rodents), small birds, snakes, lizards, frogs, insects, other invertebrates, carrion, and the eggs of birds, lizards, snakes, and tortoises. Three to four extensive meals in spring are claimed to give them enough energy for a whole season. Nevertheless, they feed whenever they come across suitable prey. Young Gila monsters can swallow up to 50% of their body weight in a single meal. Adults may eat up to one third of their body weight in one meal.The Gila monster uses its extremely acute sense of smell to locate prey. The strong, two-ended tipped tongue, which is pigmented in black-blue colors, picks up scent molecules to be transferred to the opening of the Jacobson organ around the middle of the upper mouth cavern.
+Prey may be crushed to death if large, or eaten alive, most of the time head first, and helped down by muscular contractions and neck flexing. After food has been swallowed, the Gila monster may immediately resume tongue flicking and search behavior for identifying more prey such as eggs or young in nests. Gila monsters are able to climb trees, cacti, and even fairly straight, rough-surfaced walls.

+
+=== Pioneer beliefs ===
+In the Old West, the pioneers believed a number of myths about the Gila monster, including that the lizard had foul or toxic breath and that its bite was fatal. The Tombstone Epitaph of Tombstone, Arizona, wrote about a Gila monster that a local person caught on May 14, 1881:
+
+This is a monster, and no baby at that, it being probably the largest specimen ever captured in Arizona. It is 27 inches long and weighs 35 lb. It was caught by H. C. Hiatt on the road between Tombstone and Grand Central Mill, and was purchased by Messrs. Ed Baker and Charles Eastman, who now have it on exhibition at Kelley's Wine House, next door above Grand Hotel, Allen Street. Eastern people who have never seen one of these monsters should not fail to inspect his Aztecship, for they might accidentally stumble upon one some fine day and get badly frightened, except they know what it is.
+On May 8, 1890, southeast of Tucson, Arizona Territory, Empire Ranch owner Walter Vail captured and thought he had killed a Gila monster. He tied it to his saddle and it bit the middle finger of his right hand and would not let go. A ranch hand pried open the lizard's mouth with a pocket knife, cut open his finger to stimulate bleeding, and then tied saddle strings around his finger and wrist. They summoned Dr. John C. Handy of Tucson, who took Vail back to Tucson for treatment, but Vail experienced swollen and bleeding glands in his throat for sometime afterward.Dr. Handy's friend, Dr. George Goodfellow of Tombstone, was among the first to research the actual effects of Gila monster venom. Scientific American reported in 1890, "The breath is very fetid, and its odor can be detected at some little distance from the lizard. It is supposed that this is one way in which the monster catches the insects and small animals which form a part of its food supply – the foul gas overcoming them." Goodfellow offered to pay local residents $5.00 for Gila monster specimens. He bought several and collected more on his own. In 1891, he purposely provoked one of his captive lizards into biting him on his finger. The bite made him ill and he spent the next five days in bed, but he completely recovered. When Scientific American ran another ill-founded report on the lizard's ability to kill people, he wrote in reply and described his own studies and personal experience. He wrote that he knew several people who had been bitten by Gila monsters, but had not died from the bite.
+
+
+=== Venom delivery ===
+
+The Gila monster produces venom in modified salivary glands at the end of its lower jaws, unlike snakes, whose venom is produced in glands behind the eyes. The Gila monster lacks strong musculature in glands above the eyes; instead, in Heloderma, the venom is propelled from the gland via a tubing to the base of the lower teeth and then by capillary forces into two grooves of the tooth and then chewed into the victim. The teeth are tightly anchored to the jaw (pleurodont). Broken and regular replacement teeth have to wait every time to go into position in a determinate "wavelike" sequence. They change/replace their teeth during their entire life. The Gila monster's bright colors might be suitable to teach predators not to bother this "painful" creature. Because the Gila monster's prey consists mainly of eggs, small animals, and otherwise "helpless" prey, the Gila monster's venom is thought to have evolved for defensive rather than for hunting use.
+
+
+=== Toxicity ===
+The venom of a Gila monster is normally not fatal to healthy adult humans. No reports of fatalities have been confirmed after 1930, and the rare fatalities recorded before that time occurred in adults who were intoxicated by alcohol or had mismanaged the treatment of the bite. The Gila monster can bite quickly, and may not release the victim without intervention. If bitten, the victim may attempt to fully submerge the lizard in water, pry the jaws open with a knife or stick, or physically yank the lizard free. While pulling the lizard directly increases risk of severe lacerations from the lizard's sharp teeth, it may also mitigate envenomation. Symptoms of the bite include excruciating pain, edema, and weakness associated with a rapid drop in blood pressure.
+YouTuber and wildlife educator Coyote Peterson described the bite as "like hot lava coursing through your veins" and claimed it was "the worst pain [he] had ever experienced." It is generally regarded as the most painful venom produced by any vertebrate.More than a dozen peptides and other substances have been isolated from the Gila monster's venom, including hyaluronidase, serotonin, phospholipase A2, and several kallikrein-like glycoproteins responsible for the pain and edema caused by a bite, without producing a compartment syndrome. Four potentially lethal toxins have been isolated from the Gila monster's venom, which cause hemorrhage in internal organs and exophthalmos (bulging of the eyes), and helothermine, which causes lethargy, partial paralysis of the limbs, and hypothermia in rats. Some are similar in action of the vasoactive intestinal peptide (VIP), which relaxes smooth muscle and regulates water and electrolyte secretion between the small and large intestines. These bioactive peptides are able to bind to VIP receptors in many different human tissues. One of these, helodermin, has been shown to inhibit the growth of lung cancer.
+
+
+=== Toxins and drug research ===
+The constituents of H. suspectum venom that have received the most attention from researchers are the bioactive peptides, including helodermin, helospectin, exendin-3, and exendin-4. Exendin-4, which is specific for H. suspectum, has formed the basis of a class of medications for the treatment of type 2 diabetes, known as Glucagon-like peptide-1 agonists.
+In 2005, the U.S. Food and Drug Administration approved the drug exenatide (marketed as Byetta) for the management of type 2 diabetes. It is an extravagantly synthetic blueprint of the protein exendin-4, isolated from the Gila monster's venom. In a 3-year study with people with type 2 diabetes, exenatide showed healthy sustained glucose levels. The effectiveness is because the lizard protein is 53% identical to glucagon-like peptide-1 analog (GLP-1), a hormone released from the human digestive tract that helps to regulate insulin and glucagon. Using a sophisticated injection formula with sustained release of the drug the lizard protein remains effective much longer than the human hormone, This helps diabetics keep their blood glucose levels under control for a week by a single injection. Exenatide also slows the emptying of the stomach and causes a decrease in appetite, contributing to weight loss.The antidiabetic exenatide (Byetta®) from the venomous Gila monster is also an example of a medical value of venom peptides, targeting G protein-coupled receptors (GPCRs).
+
+
+== Lifecycle ==
+The Gila monster emerges from brumation in early March. H. suspectum sexually matures at 4–5 years old. It mates in April and May. The male initiates courtship by flicking his tongue to search for the female's scent. If the female rejects his advances, she will bite him and chase him away. When successful, copulation has been observed in captivity to last from 15 minutes to two and a half hours. There is only a single record of attempted mating outside of a shelter. The female lays eggs at the end of May into June. A clutch may consist of up to six (rarely up to eight) eggs. The incubation in captivity lasts about 5 months, depending on the incubation temperature. The hatchlings are about 16 cm (6.3 in) long and can bite and inject venom as soon as they are hatched.
+The egg development and hatching time of young in the wild has been a subject of ongoing speculation. The first model stated that youngsters hatch in fall and stay underground. The second theory postulated a nearly developed embryo remains inside the egg over winter and hatches in spring. Hatchlings (weight about 35 g (1.2 oz)) are observed at the end of April to early June.
+Discussions of the exact egg development and hatching cycle of the Gila monster came to an abrupt and unexpected end on October 28, 2016, when a backhoe was digging at the outer walls of a house in a suburb of northern Tucson. The backhoe extracted a nest of H. suspectum with five eggs in the process of hatching. The Gila monster is now known to hatch near the end of October and immediately proceed into hibernation without surfacing. They then appear on the surface from May through June the following year when prey should be abundant.
+In summer, Gila monsters gradually spend less time on the surface to avoid the hottest part of the season; occasionally, they may be active at night. Females that have laid eggs are exhausted and thin, fighting for survival, and have to spend extra effort to "reconstitute". The brumation of Gila monsters begins in October. Gila monsters can live up to 40 years in captivity, though rarely.
+Little is known about the social behavior of H. suspectum, but it has been observed engaging in male to male combat, in which the dominant male lies on top of the subordinate one and pins it with its front and hind limbs. While fighting, both lizards arch their bodies, pushing against each other and twisting around in an effort to gain the dominant position. A “wrestling match” ends when the pressure exerts their forces, although bouts may be repeated. These bouts are typically observed in the mating season. Males with greater strength and endurance are thought to enjoy greater reproductive success. Although the Gila monster has a low metabolism and one of the lowest lizard sprint speeds, it has one of the highest aerobic scope values (the increase in oxygen consumption from rest to maximum metabolic exertion) among lizards, allowing it to engage in intense aerobic activity for a sustained period of time.
+
+
+== Conservation status ==
+Gila monsters are listed as near threatened by the IUCN. They are listed as "Apparently Secure" by NatureServe.In 1952, the Gila monster became the first venomous animal to be given legal protection. They are now protected in all states of their distribution. International trade in the species is regulated under Appendix II of CITES.
+
+
+=== Relocation ===
+"Possibly the greatest threat to the continued existence of helodermatids is the man-made destruction of their habitat as the land is developed for construction or to create more cultivable land." Gila monsters found in these situations and relocated – with best intentions – up to 1.2 km (0.75 mi)  away, return to where they were found within 2 months and at great effort. This is up to five times the normal energy use than if they had not been removed, which uses up their energy stores unnecessarily. The same is true for animals relocated to appropriate habitats. Besides this, they also become more exposed to predators. Therefore, the process of simple relocation is "naïve" and potentially dangerous for both the relocated animals and existing populations and for the inhabitants of the region where the resettlement is taking place. If relocating the lizards further away, they might be totally disoriented, thus their survival is still very questionable. A more successful strategy would be, for example, if the new "settlers" were offered intensive education about this species (e.g., limited toxicity, lifestyle) with the aim of tolerating the reptile or even being proud of having this unique "roommate" in one's own neighborhood.In 1963, the San Diego Zoo became the first zoo to successfully breed Gila monsters in captivity. In the last two decades, experienced breeders have shared their knowledge and expertise to give advice to other herpetologists on overcoming the difficulties in Heloderma reproduction under human care.
+
+
+== Relationship with humans ==
+Though the Gila monster is venomous, in having laggard movement, it poses little threat to humans. However, it has a fearsome reputation and is often killed by humans. Myths that have formed about the Gila monster include that the animal's breath is toxic enough to kill humans, that it can spit venom like a spitting cobra, that it can leap several feet in the air to attack, and that the Gila monster did not have an anus and therefore expelled waste from its mouth, the source of its venom and "fetid breath" (likely stemming from the fact that its venom in fact has an intense, specific smell). Among Native American tribes, the Gila monster had a mixed standing. The Apache believed its breath could kill a man, and the Tohono O'Odham and the Pima believed it possessed a spiritual power that could cause sickness. In contrast, the Seri and the Yaqui believed the Gila monster's hide had healing properties.
+The Gila monster starred as a monster in the film The Giant Gila Monster (though the titular monster was actually portrayed by a Mexican beaded lizard). It played a minor role in the motion picture The Treasure of the Sierra Madre. In Brock Brower's 1971 novel The Late Great Creature, fictional horror movie star Simon Moro is presented as famous for playing the reptilian werewolf-like Gila Man. The 2011 animated film Rango featured a Gila monster as an Old West outlaw named Bad Bill, voiced by Ray Winstone.The Gila monster has also seen usage as a mascot and state symbol. The official mascot of Eastern Arizona College located in Thatcher, Arizona, is Gila Hank, a gun-toting, cowboy hat-wearing Gila monster.  In 2017, the Vegas Golden Knights selected a Gila monster named Chance as their official mascot. In 2019, the state of Utah made the Gila monster its official state reptile.

+The Gila monster (Heloderma suspectum,  HEE-lə) is a species of venomous lizard native to the Southwestern United States and the northwestern Mexican state of Sonora. It is a heavy, typically slow-moving reptile, up to 56 centimetres (22 in) long, and it is the only venomous lizard native to the United States. Its venomous close relatives, the four beaded lizards (all former subspecies of Heloderma horridum) inhabit Mexico and Guatemala. The Gila monster is sluggish in nature, so it is not generally dangerous and very rarely poses a real threat to humans. However, it has a fearsome reputation and is sometimes killed in spite of the species being protected by state law in Arizona.
+
+
+== History ==
+
+The name "Gila" refers to the Gila River Basin in the U.S. states of Arizona and New Mexico, where the Gila monster was once plentiful. Heloderma means "studded skin", from the Ancient Greek words helos (ἧλος), "the head of a nail or stud", and derma (δέρμα), "skin". Suspectum comes from the describer, paleontologist Edward Drinker Cope. At first, this new specimen of Heloderma was misidentified and considered to be a northern variation of the beaded lizard already known to live in Mexico. He suspected that the lizard might be venomous due to the grooves in the teeth.
+
+The Gila monster is the largest extant lizard species native to North America north of the Mexican border. Its snout-to-vent length ranges from 26 to 36 cm (10 to 14 in). The tail is about 20% of the body size, and the largest specimens may reach 51 to 56 cm (20 to 22 in) in total length. Body mass is typically in the range of 550 to 800 g (1.21 to 1.76 lb). They appear strong in their body structure with a stout snout, massive head, and "little"-appearing eyes, which can be protected by a nictitating membrane.The Gila monster has four close living relatives, all of which are beaded lizards. There are three species in Mexico: Heloderma exasperatum, Heloderma horridum and Heloderma alvarezi, as well as another species in Guatemala: Heloderma charlesbogerti.The evolutionary history of the Helodermatidae may be traced back to the Cretaceous period (145 to 166 million years ago), when Gobiderma pulchrum and Estesia mongolensis were present. The genus Heloderma has existed since the Miocene, when H. texana lived. Fragments of osteoderms from the Gila monster have been found in Late Pleistocene (10,000 to 8,000 years ago) deposits near Las Vegas, Nevada. Because the helodermatids have remained relatively unchanged morphologically, they are occasionally regarded as living fossils. Although the Gila monster appears closely related to the monitor lizards (varanids) of Africa, Asia, and Australia, their wide geographical separation and distinct features indicate that Heloderma is better placed in a separate family.
+
+
+== Skin ==
+
+The scales of the head, back, and tail contain little pearl-shaped bones (osteoderms) similar to those found in the beaded lizards from further south. The scales of the belly are free from osteoderms. Female Gila monsters go through a total shed lasting about 2 weeks before depositing their eggs. The dorsal part is often shed in one large piece. Adult males normally shed in smaller segments in August. The young seem to be in constant shed. Adults have more or less yellow to pink colors on a black surface. Hatchlings have a uniform, simple, and less colorful pattern. This drastically changes within the first 6 months of their lives. Hatchlings from the northern area of the species' distribution have a tendency to retain most of their juvenile pattern.
+
+The heads of males are very often larger and more triangular-shaped than in females. The length of the tail of the two sexes is statistically very similar, so it does not help in differentiation of the sexes. Individuals with stout tail ends occur in both nature and under human breeding.
+
+
+== Distribution and habitat ==
+
+The Gila monster is found in the Southwestern United States and Mexico, a range including Sonora, Arizona, parts of California, Nevada, Utah, and New Mexico. No records have been given from Baja California. They inhabit scrubland, succulent desert, and oak woodland, seeking shelter in burrows, thickets, and under rocks in locations with a favorable microclimate and adequate humidity. Gila monsters depend on water resources and can be observed in puddles of water after a summer rain. They avoid living in open areas, such as flats and open grasslands.
+
+
+== Ecology ==
+
+Gila monsters spend 90% of their lifetime underground in burrows or rocky shelters. They are active in the morning during the dry season (spring and early summer). The lizards move to different shelters every 4–5 days up to the beginning of the summer season. By doing so, they optimize for a suitable microhabitat. Later in the summer, they may be active on warm nights or after a thunderstorm. They maintain a surface body temperature of about 30 °C (86 °F). Close to 37 °C (99 °F), they are able to decrease their body temperature by up to 2 °C (3.6 °F) by an activated, limited evaporation via the cloaca. One study investigating a population of Gila monsters in southwestern Utah noted that the lizard's activity peaked from late April to mid June. The average distance traveled during their bouts of activity was 210 metres (690 ft), but on occasion some lizards would travel distances greater than 1 kilometre (0.62 mi). During the Gila monster's active season of approximately 90 days, only ten days were spent active. Gila monsters are slow sprinters, but they have relatively high endurance and maximal aerobic capacity (VO2 max) compared to other lizards. They are preyed upon by coyotes, badgers and raptors.

The incubation in captivity lasts about 5 months, depending on the incubation temperature. The hatchlings are about 16 cm (6.3 in) long and can bite and inject venom as soon as they are hatched.
+The egg development and hatching time of young in the wild has been a subject of ongoing speculation. The first model stated that youngsters hatch in fall and stay underground. The second theory postulated a nearly developed embryo remains inside the egg over winter and hatches in spring. Hatchlings (weight about 35 g (1.2 oz)) are observed at the end of April to early June.
+Discussions of the exact egg development and hatching cycle of the Gila monster came to an abrupt and unexpected end on October 28, 2016, when a backhoe was digging at the outer walls of a house in a suburb of northern Tucson. The backhoe extracted a nest of H. suspectum with five eggs in the process of hatching. The Gila monster is now known to hatch near the end of October and immediately proceed into hibernation without surfacing. They then appear on the surface from May through June the following year when prey should be abundant.
+In summer, Gila monsters gradually spend less time on the surface to avoid the hottest part of the season; occasionally, they may be active at night. Females that have laid eggs are exhausted and thin, fighting for survival, and have to spend extra effort to "reconstitute". The brumation of Gila monsters begins in October. Gila monsters can live up to 40 years in captivity, though rarely.
+Little is known about the social behavior of H. suspectum, but it has been observed engaging in male to male combat, in which the dominant male lies on top of the subordinate one and pins it with its front and hind limbs. While fighting, both lizards arch their bodies, pushing against each other and twisting around in an effort to gain the dominant position. A “wrestling match” ends when the pressure exerts their forces, although bouts may be repeated. These bouts are typically observed in the mating season. Males with greater strength and endurance are thought to enjoy greater reproductive success. Although the Gila monster has a low metabolism and one of the lowest lizard sprint speeds, it has one of the highest aerobic scope values (the increase in oxygen consumption from rest to maximum metabolic exertion) among lizards, allowing it to engage in intense aerobic activity for a sustained period of time.
+
+
+== Conservation status ==
+Gila monsters are listed as near threatened by the IUCN. They are listed as "Apparently Secure" by NatureServe.In 1952, the Gila monster became the first venomous animal to be given legal protection. They are now protected in all states of their distribution. International trade in the species is regulated under Appendix II of CITES.
+
+
+=== Relocation ===
+"Possibly the greatest threat to the continued existence of helodermatids is the man-made destruction of their habitat as the land is developed for construction or to create more cultivable land." Gila monsters found in these situations and relocated – with best intentions – up to 1.2 km (0.75 mi)  away, return to where they were found within 2 months and at great effort. This is up to five times the normal energy use than if they had not been removed, which uses up their energy stores unnecessarily. The same is true for animals relocated to appropriate habitats. Besides this, they also become more exposed to predators. Therefore, the process of simple relocation is "naïve" and potentially dangerous for both the relocated animals and existing populations and for the inhabitants of the region where the resettlement is taking place. If relocating the lizards further away, they might be totally disoriented, thus their survival is still very questionable. A more successful strategy would be, for example, if the new "settlers" were offered intensive education about this species (e.g., limited toxicity, lifestyle) with the aim of tolerating the reptile or even being proud of having this unique "roommate" in one's own neighborhood.In 1963, the San Diego Zoo became the first zoo to successfully breed Gila monsters in captivity. In the last two decades, experienced breeders have shared their knowledge and expertise to give advice to other herpetologists on overcoming the difficulties in Heloderma reproduction under human care.
+
+
+== Relationship with humans ==
+Though the Gila monster is venomous, in having laggard movement, it poses little threat to humans. However, it has a fearsome reputation and is often killed by humans. Myths that have formed about the Gila monster include that the animal's breath is toxic enough to kill humans, that it can spit venom like a spitting cobra, that it can leap several feet in the air to attack, and that the Gila monster did not have an anus and therefore expelled waste from its mouth, the source of its venom and "fetid breath" (likely stemming from the fact that its venom in fact has an intense, specific smell). Among Native American tribes, the Gila monster had a mixed standing. The Apache believed its breath could kill a man, and the Tohono O'Odham and the Pima believed it possessed a spiritual power that could cause sickness. In contrast, the Seri and the Yaqui believed the Gila monster's hide had healing properties.
+The Gila monster starred as a monster in the film The Giant Gila Monster (though the titular monster was actually portrayed by a Mexican beaded lizard). It played a minor role in the motion picture The Treasure of the Sierra Madre. In Brock Brower's 1971 novel The Late Great Creature, fictional horror movie star Simon Moro is presented as famous for playing the reptilian werewolf-like Gila Man. The 2011 animated film Rango featured a Gila monster as an Old West outlaw named Bad Bill, voiced by Ray Winstone.The Gila monster has also seen usage as a mascot and state symbol. The official mascot of Eastern Arizona College located in Thatcher, Arizona, is Gila Hank, a gun-toting, cowboy hat-wearing Gila monster.  In 2017, the Vegas Golden Knights selected a Gila monster named Chance as their official mascot. In 2019, the state of Utah made the Gila monster its official state reptile.

+The spiny turtle (Heosemys spinosa) is a South-East Asian turtle species. It inhabits lowland and hill rainforest, usually in the vicinity of small streams, mainly in hill areas up to 900 m above sea level.
+
+
+== Description ==
+
+The origin of its common and specific name is immediately apparent from the sharp, pointed, spiky-edged carapace, and spiny keel, of this unique turtle, also known as the 'cog-wheel turtle'.
+
+
+== Distribution ==
+The spiny turtle is known from Brunei, Indonesia, Malaysia, Myanmar, the Philippines, Singapore, and Thailand.
+
+
+== Reproduction ==
+Mating behaviour appears to be triggered by rain; in captivity, spraying males with water results in them chasing females and attempting to mount. Nothing is known of nesting behaviour in the wild. One, two, or rarely three eggs are laid per clutch; in captivity, laying usually occurs in the night or early morning. Females produce up to three clutches per year. A plastron hinge develops to ease laying. It has been bred in captivity several times; in three cases the incubation time was 106, 110, and 145 days.

+The hippopotamus ( HIP-ə-POT-ə-məs; PL: hippopotamuses or hippopotami; Hippopotamus amphibius), also called the hippo, common hippopotamus, or river hippopotamus, is a large semiaquatic mammal native to sub-Saharan Africa. It is one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus (Choeropsis liberiensis or Hexaprotodon liberiensis). Its name comes from the ancient Greek for "river horse" (ἱπποπόταμος).
+Aside from elephants and rhinos, the hippopotamus is the largest land mammal. It is also the largest extant land artiodactyl. Despite their physical resemblance to pigs and other terrestrial even-toed ungulates, the closest living relatives of the hippopotamids are cetaceans (whales, dolphins, porpoises, etc.), from which they diverged about 55 million years ago. Hippos are recognisable for their barrel-shaped torsos, wide-opening mouths with large canine tusks, nearly hairless bodies, pillar-like legs, and large size: adults average 1,500 kg (3,310 lb) for bulls (males) and 1,300 kg (2,870 lb) for cows (females). Despite its stocky shape and short legs, it is capable of running 30 km/h (19 mph) over short distances.
+Hippos inhabit rivers, lakes, and mangrove swamps. Territorial bulls each preside over a stretch of water and a group of five to thirty cows and calves. Mating and birth both occur in the water. During the day, hippos remain cool by staying in water or mud, emerging at dusk to graze on grasses. While hippos rest near each other in the water, grazing is a solitary activity and hippos typically do not display territorial behaviour on land. Hippos are among the most dangerous animals in the world due to their aggressive and unpredictable nature. They are threatened by habitat loss and poaching for their meat and ivory (canine teeth).
+
+
+== Etymology ==
+The Latin word hippopotamus is derived from the ancient Greek ἱπποπόταμος, hippopótamos, from ἵππος, híppos, 'horse', and ποταμός, potamós, 'river', meaning "horse of the river". In English, the plural is "hippopotamuses", but "hippopotami" is also used.
+
+
+== Taxonomy and origins ==
+
+
+=== Classification ===
+The modern hippopotamus and the pygmy hippopotamus are the only living members of the family Hippopotamidae. Some taxonomists place hippos and anthracotheres in the superfamily Anthracotheroidea. Hippopotamidae are classified along with other even-toed ungulates in the order Artiodactyla.: 39–40 
+
+Five subspecies of hippos have been described based on morphological differences in their skulls as well as differences in geographical range:: 3 
+H. a. amphibius – (the nominate subspecies) ranges from Gambia east to Ethiopia and then south to Mozambique and historically ranged as far north as Egypt; its skull is distinguished by a moderately reduced preorbital region, a bulging dorsal surface, elongated mandibular symphysis and larger chewing teeth.
+H. a. kiboko – found in Kenya and Somalia; was noted to be smaller and more lightly coloured than other hippos with wider nostrils, somewhat longer snout and more rounded and relatively raised orbits with the space between them being incurved.
+H. a. capensis – found in Zambia and South Africa; distinguished by wider orbits.
+H. a. tschadensis – ranges between Chad and Niger; featured a slightly shorter but broader face, and pronounced, forward-facing orbits.
+H. a. constrictus – ranged from the southern Democratic Republic of Congo to Angola and Namibia; skull characterised by a thicker preorbital region, shorter snout, flatter dorsal surface, reduced mandibular symphysis and smaller chewing teeth.The suggested subspecies above were never widely used or validated by field biologists; the described morphological differences were small enough that they could have resulted from simple variation in nonrepresentative samples.: 2  A study examining mitochondrial DNA from skin biopsies taken from 13 sampling locations found "low, but significant, genetic differentiation" among H. a. amphibius, H. a. capensis, and H. a. kiboko. Neither H. a. tschadensis nor H. a. constrictus have been tested.
+
+
+=== Evolution ===
+
+Until 1909, naturalists classified hippos together with pigs based on molar patterns. Several lines of evidence, first from blood proteins, then from molecular systematics and DNA and the fossil record, show their closest living relatives are cetaceans (whales, dolphins, and porpoises). The common ancestor of hippos and whales branched off from Ruminantia and the rest of the even-toed ungulates; the cetacean and hippo lineages split soon afterwards.
+
+The most recent theory of the origins of Hippopotamidae suggests hippos and whales shared a common semiaquatic ancestor that branched off from other artiodactyls around 60 million years ago. This hypothesised ancestral group likely split into two branches again around 54 million years ago.One branch would evolve into cetaceans, possibly beginning about 52 million years ago, with the protowhale Pakicetus and other early whale ancestors collectively known as Archaeoceti. This group eventually underwent aquatic adaptation into the completely aquatic cetaceans. The other branch became the anthracotheres, a large family of four-legged beasts, the earliest of which in the late Eocene would have resembled skinny hippos with comparatively smaller, narrower heads. All branches of the anthracotheres, except that which evolved into Hippopotamidae, became extinct during the Pliocene, leaving no descendants.A rough evolutionary lineage of the hippo can thus be traced from Eocene and Oligocene species: from Anthracotherium and Elomeryx to the Miocene species Merycopotamus and Libycosaurus and finally the very latest anthracotheres in the Pliocene. These groups lived across Eurasia and Africa. The discovery of Epirigenys in East Africa, which was likely a descent of Asian anthracotheres and a sister taxon to Hippopotamidae suggests that hippo ancestors likely entered Africa from Asia around 35 million years ago. An early hippopotamid is the genus Kenyapotamus, which lived in Africa from 15 to 9 million years ago. Hippopotamid species would spread across Africa and Eurasia, including the modern pygmy hippo. From 7.5 to 1.8 million years ago, a possible ancestor to the modern hippo, Archaeopotamus, lived in Africa and the Middle East.
+
+
+=== Extinct species ===
+Three species of Malagasy hippopotamus became extinct during the Holocene on Madagascar, the last of them within the past 1,000 years. The Malagasy hippos were smaller than the modern hippo, a likely result of the process of insular dwarfism. Fossil evidence indicates many Malagasy hippos were hunted by humans, a factor in their eventual extinction. Isolated individual Malagasy hippos may have survived in remote pockets; in 1976, villagers described a living animal called the kilopilopitsofy, which may have been a Malagasy hippo.An extinct species, Hippopotamus antiquus, ranged throughout Europe, extending as far north as Britain during the Early and Middle Pleistocene epochs, before being replaced by the modern H. amphibius during the latter part of the Middle Pleistocene. The Pleistocene also saw a number of dwarf species evolve on several Mediterranean islands, including Crete (Hippopotamus creutzburgi), Cyprus (the Cyprus dwarf hippopotamus, Hippopotamus minor), Malta (Hippopotamus melitensis), and Sicily (Hippopotamus pentlandi). Of these, the Cyprus dwarf hippo survived until the end of the Pleistocene or early Holocene. Evidence from the archaeological site Aetokremnos continues to cause debate on whether or not the species was driven to extinction, or even encountered, by man. Across Eurasia, the hippopotamus became extinct between 50,000 and 16,000 years ago.
+
+
+== Characteristics and adaptations ==
+
+The hippopotamus is a megaherbivore and is exceeded in size among land animals only by elephants and some rhinoceros species. Bulls weigh around 1,500 to 1,800 kg (3,300 to 3,960 lb) and cows around 1,300 to 1,500 kg (2,860 to 3,300 lb). Exceptionally large males have been recorded reaching 2,660 kg (5,860 lb). Male hippos appear to continue growing throughout their lives, while females reach maximum weight at around age 25. Hippos measure 2.90 to 5.05 m (9.5 to 16.6 ft) long, including a tail of about 35 to 56 cm (1.15 to 1.84 ft) in length and 1.30 to 1.65 m (4.3 to 5.4 ft) tall at the shoulder, with males and females ranging 1.40 to 1.65 m (4.6 to 5.4 ft) and 1.30 to 1.45 m (4.3 to 4.8 ft) tall at the shoulder respectively. The species has a typical head-body length of 3.3–3.45 m (10.8–11.3 ft) and an average standing height of 1.4 m (4.6 ft) at the shoulder.Hippos have barrel-shaped bodies with short tails and legs, and an hourglass-shaped skull with a long snout.: 3, 19  Their skeletal structures are graviportal, adapted to carrying their enormous weight,: 8  and their dense bones and low centre of gravity allows them to sink and move along the bottom of the water. Hippopotamuses have small legs (relative to other megafauna) because the water in which they live reduces the weight burden. The pelvis rests at an angle of 45 degrees.: 9  Hippos usually trot to move quickly on land and can gallop at 30 km/h (19 mph) when needed. They are incapable of jumping but can walk up steep banks. Despite their rounded appearance, hippos have little fat.: 3 The eyes, ears, and nostrils of hippos are placed high on the roof of their skulls. This allows these organs to remain above the surface while the rest of the body is submerged.: 259  The nostrils and ears can close when underwater while nictitating membranes cover the eyes.: 4, 116  Despite being semiaquatic and having webbed feet, an adult hippo is not a particularly good swimmer, nor can it float. It rarely enters deep water; when does, the animal moves by bouncing off the bottom. A hippo surfaces every four to six minutes, while young to breathe every two to three minutes.: 3–4  The hippopotamus sleeps with both hemispheres of the brain resting, as in all land mammals, and usually sleeps in land or in water with the nostrils exposed. Despite this, it may be capable of sleeping while submerged, intermittently surfacing to breathe without waking. They appear to transition between different phases of sleep more quickly than other mammals.
+
+The hippo's jaw is powered by huge masseter and digastric muscles which give them large, droopy cheeks.: 259  The jaw hinge allows the animal to open its mouth at almost 180°.: 17  A folded orbicularis oris muscle allows the hippo to attain an extreme gape without tearing any tissue. On the lower jaw, the incisors and canines grow continuously, the former reaching 40 cm (1 ft 4 in), while the latter can grow to up to 50 cm (1 ft 8 in). The lower canines are sharpened through contact with the smaller upper canines. The canines and incisors are used mainly for combat instead of feeding. Hippos rely on their flattened, horny lips to grasp and pull grasses which are then ground by the molars.: 259, 263  The hippo is considered to be a pseudoruminant; it has a complex three-chambered stomach, but does not "chew cud".: 22 
+
+Hippo skin is 6 cm (2 in) thick across much of its body with little hair.: 260  The animal is mostly purplish-grey or blue-black, but brownish-pink on the underside around the eyes and ears.: 260  Their skin secretes a natural, red-coloured sunscreen substance that is sometimes referred to as "blood sweat" but is neither blood nor sweat. This secretion is initially colourless and turns red-orange within minutes, eventually becoming brown. Two highly acidic pigments have been identified in the secretions; one red (hipposudoric acid) and one orange (norhipposudoric acid), which inhibit the growth of disease-causing bacteria and their light-absorption profile peaks in the ultraviolet range, creating a sunscreen effect. Regardless of diet, all hippos secrete these pigments so food does not appear to be their source; rather, they may be synthesised from precursors such as the amino acid tyrosine. This natural sunscreen cannot prevent the animal's skin from cracking if it stays out of water too long.The testes of the males do not fully descend and a scrotum is not present. In addition, the penis retracts into the body when not erect. The genitals of the female hippos are unusual in that the vagina is ridged and the vulval vestibule has two large, protruding diverticula. Both of these have an unknown function.: 28–29 A hippo's lifespan is typically 40 to 50 years.: 277  Donna the Hippo was one of the oldest living hippos in captivity. She lived at the Mesker Park Zoo in Evansville, Indiana, in the US until her death in 2012 at the age of 61. The oldest hippo ever recorded was called Bertha; she had lived in the Manila Zoo in the Philippines since it first opened in 1959. When she died in 2017, her age was estimated to be 65.
+
+
+== Distribution and status ==
+
+Hippopotamus amphibius was widespread in North Africa and Europe during the Eemian (130–115,000 years ago), with remains found as far north as England. Archaeological evidence exists of its presence in the Levant, dating to less than 3,000 years ago. The species was common in Egypt's Nile region during antiquity, but it has since been driven out. According to Pliny the Elder, in his time, the best location in Egypt for capturing this animal was in the Saite nome; the animal could still be found along the Damietta branch of the Nile after the Arab Conquest in 639. Reports of the slaughter of the last hippo in Natal Province were made at the end of the 19th century. Hippos are still found in the rivers and lakes of the northern Democratic Republic of the Congo, Uganda, Tanzania, and Kenya, north through to Ethiopia, Somalia, and Sudan, west to The Gambia, and south to South Africa.Genetic evidence suggests common hippos in Africa experienced a marked population expansion during or after the Pleistocene, attributed to an increase in water bodies at the end of the era. These findings have important conservation implications, as hippo populations across the continent are currently threatened by loss of access to fresh water. Hippos are also subject to unregulated hunting and poaching. The species is included in Appendix II of the Convention on International Trade in Endangered Species (CITES) meaning international export/import (including in parts and derivatives) requires CITES documentation to be obtained and presented to border authorities.As of 2017, the IUCN Red List drawn up by the International Union for Conservation of Nature (IUCN) lists the species as vulnerable, with a stable population estimated between 115,000 and 130,000 animals. The hippo population has declined most dramatically in the Democratic Republic of the Congo. By 2005, the population in Virunga National Park had dropped to 800 or 900 from around 29,000 in the mid-1970s. This decline is attributed to the disruptions caused by the Second Congo War. The poachers are believed to be Mai-Mai rebels, underpaid Congolese soldiers, and local militia groups. Reasons for poaching include the belief hippos are harmful to society, as well as financial gain. As of 2016, the Virunga hippo population appears to have increased again, possibly due to better protection form park rangers, who have worked with local fishermen. The sale of hippo meat is illegal, but black-market sales are difficult for Virunga National Park officers to track. Hippo meat is highly valued in some areas of central Africa and the teeth may be used as a replacement for elephant ivory.A population of hippos exists in Colombia, descended from captive individuals that escaped from Pablo Escobar's estate after this death in 1993. Their numbers grew to 100 by the 2020s and ecologists believe the population should be eradicated, as they are breeding rapidly and are an increasing menace to humans and the environment. Attempts to control them include sterilisation and culling.
+
+
+== Behaviour and ecology ==
+
+Hippos are semiaquatic and require enough water to immerse in, while being close to grass. They prefer relatively still waters with gently sloping shores though, male hippos may also be found in very small numbers in more rapid waters with rocky slopes.: 264  Hippos mostly live in freshwater habitat, but can be found in estuaries.Hippos spend most the day in water to stay cool and hydrated. Just before night begins, they leave the water to foraging on land. Like most herbivores, hippos will consume a variety of plants if presented with them in captivity, but their diet in nature consists almost entirely of grass, with only minimal consumption of aquatic plants. A hippo will travel 3–5 km (1.9–3.1 mi) per night, eating around 40 kg (88 lb) of grass. By dawn, they are back in the water. On occasion, hippos have been filmed eating carrion, usually near the water. There are other reports of meat-eating and even cannibalism and predation. The stomach anatomy of lacks adaptions to carnivory, and meat-eating is likely caused by not having enough nutrients or just an abnormal behaviour.: 82–84 Because of their size and their habit of taking the same paths to feed, hippos can have a significant impact on the land across which they walk, keeping the land clear of vegetation and depressing the ground. Over prolonged periods, hippos can divert the paths of swamps and channels. By defecating in the water, the animals also appear to pass on microbes from their gut, affecting the biogeochemical cycle.
+
+
+=== Social interaction ===
+
+It is challenging to study the interaction of bulls and cows because hippos are not sexually dimorphic, so cows and young bulls are almost indistinguishable in the field. Hippo pods fluctuate but can contain over 100 hippos. Although they lie close together, adults develop almost no social bonds. Males establish territories in water but not land, and these may range 250–500 m (270–550 yd) in lakes and 50–100 m (55–109 yd) in rivers. Territories are abandoned when the water dries up. The bull has breeding access to all the cows in his territory. Younger bachelors are allowed to stay as long as they deter to him. A younger male may challenge the old bull for control of the territory. Within the pods, the hippos tend to segregate by sex and status. Bachelor males lounge near other bachelors, females with other females, and the territorial male is on his own. When hippos emerge from the water to graze, they do so individually.: 4–5, 49–50 
+
+Hippos engage in "muck-spreading" which involves defecating while spinning their tails to distribute the faeces over a greater area. Muck-spreading occurs both on land and in water and its function is not well understood. It is unlikely to server to territorial, as the animals only establish territories in the water. They may be used as trails between the water and grazing areas.: 5, 51–52  "Yawning" serves as a threat display. When fighting, bulls use their incisors to block each other's attacks and their large canines as offensive weapons.: 259–260  When hippos become over-populated or a habitat shrinks, bulls sometimes attempt infanticide, but this behaviour is not common under normal conditions.The most common hippo vocalisation is the "wheeze honk", which can travel over long distances in air. This call starts as a high-pitched squeal followed by a deeper, resonant call.: 5  The animals can recognise the calls of other individuals. Hippos are more likely to react to the wheeze honks of strangers than those they are more familiar with. When threatened or alarmed, they produce exhalations, and fighting bulls will bellow loudly.: 5  Hippos are recorded to produce clicks underwater which may have echolocative properties. They have the unique ability to hold their heads partially above the water and send out a cry that travels through both water and air; individuals respond both above and below water.
+
+
+=== Reproduction ===
+
+Cows reach sexual maturity at five to six years of age and have a gestation period of eight months. A study of endocrine systems revealed cows may begin puberty at as early as three or four years. Males reach maturity at around 7.5 years. Both conceptions and births are highest during the wet season. Male hippo always have mobile spermatozoa and can breed year-round.: 59–61, 66  After becoming pregnant, a female hippo will typically not begin ovulation again for 17 months.
+
+Hippos mate in the water, with the cow remaining under the surface,: 63  her head emerging periodically to draw breath. Cows  give birth in seclusion and return within 10 to 14 days. Calves are born on land or shallow water weighing on average 50 kg (110 lb) and at an average length of around 127 cm (4.17 ft). The female lays on her side when nursing, which can occur underwater or on land. The young are carried on their mothers' backs in deep water.: 4, 64 Mother hippos are very protective of their young, not allowing others to get too close. One cow was recorded protecting a calf's carcass after it had died. Calves may be temporarily kept in nurseries, guarded by one or more adults, and will play amongst themselves. Like many other large mammals, hippos are described as K-strategists, in this case typically producing just one large, well-developed infant every couple of years (rather than many small, poorly developed young several times per year, as is common among small mammals such as rodents). Calves no longer need to suckle when they are a year old.: 64 
+
+
+=== Interspecies interactions ===
+
+Hippos coexist alongside a variety of large predators in their habitats. Nile crocodiles, lions, and spotted hyenas are known to prey on young hippos. Beyond these, adult hippos are not usually preyed upon by other animals due to their aggression and size. Cases where large lion prides have successfully preyed on adult hippos have been reported, but it is generally rare. Lions occasionally prey on adults at Gorongosa National Park and calves are sometimes taken at Virunga. Crocodiles are frequent targets of hippo aggression, probably because they often inhabit the same riparian habitats; crocodiles may be either aggressively displaced or killed by hippos. In turn, very large Nile crocodiles have been observed preying occasionally on calves, "half-grown" hippos, and possibly also adult female hippos. Groups of crocodiles have also been observed finishing off still-living male hippos that were previously injured in mating battles with other males.Hippos occasionally visit cleaning stations in order to be cleaned of parasites by certain species of fishes. They signal their readiness for this service by opening their mouths wide. This is an example of mutualism, in which the hippo benefits from the cleaning while the fish receive food. Hippo defecation creates allochthonous deposits of organic matter along the river beds. These deposits have an unclear ecological function. A 2015 study concluded hippo dung provides nutrients from terrestrial material for fish and aquatic invertebrates, while a 2018 study found that their dung can be toxic to aquatic life in large quantities, due to absorption of dissolved oxygen in water bodies.The parasitic monogenean flatworm Oculotrema hippopotami infests hippopotamus eyes, mainly the nictitating membrane. It is the only monogenean species (which normally live on fish) documented to live on a mammal.
+
+
+== Hippos and humans ==
+
+The earliest evidence of human interaction with hippos comes from butchery cut marks on hippo bones found at the Bouri Formation and dated to around 160,000 years ago. 4,000–5,000 year art showing hippos being hunted have been found in the Tassili n'Ajjer Mountains of the central Sahara near Djanet.: 1  The ancient Egyptians recognised the hippo as a ferocious denizen of the Nile and representations on the tombs of nobles show the animals were hunted by humans.The hippo was also known to the Greeks and Romans. The Greek historian Herodotus described the hippo in The Histories (written circa 440 BC) and the Roman naturalist Pliny the Elder wrote about the hippo in his encyclopedia Naturalis Historia (written circa 77 AD). The Yoruba people called the hippo erinmi, which means "elephant of the water". Some individual hippos have achieved international fame. Huberta became a celebrity during the Great Depression for trekking a great distance across South Africa.: 111–112 
+
+
+=== Attacks on humans ===
+The hippo is considered to be extremely aggressive and has frequently been reported charging and attacking boats. Small boats can easily be capsized by hippos and passengers can be injured or killed by the animals, or drown in the water. In one 2014 case in Niger, a boat was capsized by a hippo and 13 people were killed. Hippos will often raid farm crops if the opportunity arises, and humans may come into conflict with them on these occasions. These encounters can be fatal to either humans or hippos.
+
+
+=== In zoos ===
+
+Hippos have long been popular zoo animals. The first record of hippos taken into captivity for display is dated to 3500 BC in Hierakonpolis, Egypt. The first zoo hippo in modern history was Obaysch, who arrived at the London Zoo on 25 May 1850, where he attracted up to 10,000 visitors a day and inspired a popular song, the "Hippopotamus Polka".Hippos generally breed well in captivity; birth rates are lower than in the wild, but this can be attributed to zoos' desire to limit births, since hippos are relatively expensive to maintain. Staring in 2015, the Cincinnati Zoo built a US$73 million exhibit to house three adult hippos, featuring a 250,000 l (66,000 US gal) tank. Modern hippo enclosures also have a complex filtration system for the animal's waste, an underwater viewing area for the visitors, and glass that may be up to 9 cm (3.5 in) thick and capable holding water under pressures of 31 kPa (4.5 psi).: 158–159  In 1987, the Toledo Zoo saw the first underwater birth by a captive hippo. The exhibit was so popular, the logo of the Toledo Zoo was updated to feature the hippos.
+
+
+=== Cultural significance ===
+
+In Egyptian mythology, the god Set takes the form of a red hippopotamus and fights Horus for control of the land, but is defeated. The goddess Tawaret is depicted as a pregnant woman with a hippo head, representing fierce maternal love. The Ijaw people of the Niger Delta wore masks of aquatic animals like the hippo when practising their water spirit cults, and hippo ivory was used in the divination rituals of the Yoruba. Hippo masks were also used in Nyau funerary rituals of the Chewa of Southern Africa.: 120  According to Robert Baden-Powell, Zulu warriors referred to hippos in war chants. The Behemoth from the Book of Job, 40:15–24 is thought to be based on the hippo.Hippos have been the subjects of various African folktales. According to a San story, when the Creator assigned each animal its place in nature, the hippos wanted to live in the water, but were refused out of fear they might eat all the fish. After begging and pleading, the hippos were finally allowed to live in the water on the condition they would eat grass instead of fish, and fling their dung so it can be inspected for fish bones. In a Ndebele tale, the hippo originally had long, beautiful hair, but it was set on fire by a jealous hare and the hippo had to jump into a nearby pool. The hippo lost most of his hair and was too embarrassed to leave the water.
+
+Hippopotamuses were rarely depicted in European art during the Renaissance and Baroque periods, due to less access to specimens by Europeans. One notable exception is Peter Paul Rubens' The Hippopotamus and Crocodile Hunt (1615–1616).: 122–123  Ever since Obaysch inspired the "Hippopotamus Polka", hippos have been popular animals in Western culture for their rotund appearance, which many consider comical. The Disney film Fantasia featured a ballerina hippo dancing to the opera La Gioconda. The film Hugo the Hippo is set in Tanzania and involves the title character trying to escape being slaughtered with the help of local children. The Madagascar films feature a hippo named Gloria.: 128–129  Hippos even inspired a popular board game, Hungry Hungry Hippos.Among the most famous poems about the hippo is "The Hippopotamus" by T. S. Eliot, where he uses the animal to represent the Catholic Church. Hippos are mentioned in the novelty Christmas song "I Want a Hippopotamus for Christmas" that became a hit for child star Gayla Peevey in 1953. They also featured in the popular "The Hippopotamous Song" by Flanders and Swann.: 128, 136 A popular internet myth reports that hippos have pink milk. Biologist David Wynick states, "I think this is an Internet legend that is oft repeated but without any evidence for it that I can find... Like all mammals, hippos produce white or off-white milk for their young."

+The roan antelope (Hippotragus equinus) is a savanna antelope found in western, central, and southern Africa. Named for its roan colour (a reddish brown), it has lighter underbellies, white eyebrows and cheeks and black faces, lighter in females. It has short, erect manes, very light beards and prominent red nostrils. It is one of the largest antelope, measuring 190–240 cm (75–94 in) from head to the base of the tail, and a 37–48 cm (15–19 in) long tail. Males weigh 242–300 kg (534–661 lb) and females 223–280 kg (492–617 lb). Its shoulder height is around 130–140 cm (51–55 in).
+
+
+== Taxonomy and evolution ==
+The roan antelope shares the genus Hippotragus with the extinct bluebuck (H. leucophaeus) and the sable antelope (H. niger), and is a member of the family Bovidae. It was first described by French naturalist Étienne Geoffroy Saint-Hilaire in 1803. The specific epithet equinus derives from the Latin equus ("horse-like"), referring to the horse-like appearance of this antelope.In 1996, an analysis of mitochondrial DNA extracted from a mounted specimen of the bluebuck found that it was outside the clade containing the roan and sable antelopes. The study therefore concluded that the bluebuck is a distinct species, and not merely a subspecies of the roan antelope. The cladogram below shows the position of the roan antelope among its relatives, following the 1996 analysis:
+In 1974, palaeoanthropologist Richard Klein studied the fossils of Hippotragus species in South Africa. Most of these were found to represent the bluebuck and the roan antelope. The roan antelope seems to have appeared in the Nelson Bay Cave region following climatic changes in the Holocene.
+
+
+=== Subspecies ===
+Six subspecies are recognised:
+H. e. bakeri (Heuglin, 1863): Occurs in Sudan (East Africa).
+H. e. cottoni Dollman and Burlace, 1928: Occurs in Angola, Botswana, the southern Democratic Republic of the Congo, central and northern Malawi, and Zambia (Southern Africa).
+H. e. equinus É. Geoffroy Saint-Hilaire, 1803: Occurs in Mozambique, South Africa and Zimbabwe (Southern Africa).
+H. e. koba (Gray, 1872): Range extends from Senegal to Benin (West Africa).
+H. e. langheldi Matschie, 1898: Occurs in Burundi, the northern Democratic Republic of the Congo, Ethiopia, Kenya, Rwanda, South Sudan, Tanzania and Uganda (East Africa).
+H. e. scharicus (Schwarz, 1913): Occurs in Cameroon, the Central African Republic, Chad and eastern Nigeria (Central Africa).
+

+
+
+== Characteristics ==
+
+
+=== Physical description ===
+The roan antelope is a large antelope with a horse-like build. It is the largest antelope in the genus Hippotragus, and one of the largest species of antelopes in the world. Only elands, bongos and large male greater kudus can exceed them in weight on average. The roan antelope stands 135–160 centimetres (53–63 in) at the shoulder, and weighs 230–320 kilograms (510–710 pounds). The head-and-body length is typically between 235 and 285 centimetres (93 and 112 inches). The dark tail, terminating in a black tuft, measures up to 54 cm (21 in).
+Characteristic features include a short, erect mane of grayish brown hair extending from the back of the neck along the midline of the back up to the withers, white patches around the eyes and the mouth on the otherwise black face, and long, narrow ears with 3–5 cm (1.2–2.0 in) long tufts. The horns are ringed and arched backwards, which can reach 100 cm (39 in) long in males, slightly shorter in females. The long legs are supported by large hooves. The short, smooth coat is brown to amber. The ventral parts are yellow to white, while the neck and the manes are gray to black.
+They are somewhat similar in appearance to the sable antelopes and can be confused where their ranges overlap. Sable antelope males are notably darker, being brownish-black rather than dark brown.
+
+
+=== Habitat and behavior ===
+Roan antelopes can be found in woodland, grassland, and savannah; mainly in the tropical and subtropical grasslands, savannas, and shrublands biome, which range in tree density from forest with a grassy understory (such as the central Zambezian Miombo woodlands) to grasslands dotted with few trees, where they eat mid-length grasses.
+They live in small herds and form harem groups of 5 to 15 animals with one dominant male. Males commonly fight among themselves for dominance of their herd, brandishing their horns while both animals are on their knees.

+The sable antelope (Hippotragus niger) is an antelope which inhabits wooded savanna in East and Southern Africa, from the south of Kenya to South Africa, with a separate population in Angola.
+
+
+== Taxonomy ==
+The sable antelope shares the genus Hippotragus with the extinct bluebuck (H. leucophaeus) and the roan antelope (H. equinus), and is a member of the family Bovidae.In 1996, an analysis of mitochondrial DNA extracted from a mounted specimen of the bluebuck showed that it is outside the clade containing the roan and sable antelopes. The cladogram below shows the position of the sable antelope among its relatives, following the 1996 analysis:
+
+
+=== Subspecies ===
+Hipotragus niger has four subspecies:
+
+The southern sable antelope (H. n. niger; also known as the common sable antelope, black sable antelope, Matsetsi sable antelope or South Zambian sable antelope) is regarded as the nominate subspecies, as it was the first one to be described and named in 1838. Often referred to as the black sable antelope because it tends to have the darkest coat, this subspecies occurs south of the Zambezi River, particularly in northern Botswana and in large numbers in the Matsetsi Valley of Zimbabwe, but it is also found in South Africa. In South Africa, most of the commercial sable antelope farmers crossed their Matsetsi sable antelope (indigenous to South Africa) with Zambian sable antelope in the hope to move nearer to the nearly extinct giant sable antelope (that was larger with bigger horns). Currently, only about 15% pure Matsetsi sable antelopes are thought to exist in South Africa. The Matsetsi sable antelope population in Zimbabwe is only 450 (down from 24,000 in 1994). The sable antelope population in South Africa is about 7,000 (commercial and in reserves). Therefore, the Matsetsi sable antelope population apparently is less than 1,500 and declining. However, most of the sable antelope in the reserves are pure Matsetsi sable antelope. Anglo-American recently started a program of breeding pure Matsetsi sable antelope commercially and keeping them pure.
+The giant sable antelope (H. n. variani; also known as the royal sable antelope) is so named because both sexes are larger and their horns are recognizably longer. It is found only in a few remaining localities in central Angola. It is classified as Critically Endangered on the IUCN Red List and is listed on Appendix I of CITES.
+The Zambian sable antelope (H. n. kirkii; also known as the West Zambian sable antelope or West Tanzanian sable antelope) occurs in central Angola, western Zambia and Malawi and has the largest geographic range of the four subspecies, which extends north of the Zambezi River through Zambia, the eastern Democratic Republic of the Congo and Malawi into southwestern Tanzania. It is classified as Vulnerable.
+The eastern sable antelope (H. n. roosevelti; also known as the Shimba sable antelope) is the smallest of the four subspecies. It occurs in the coastal hinterlands of southern Kenya, particularly in the Shimba Hills National Reserve, and ranges through the region east of Tanzania's eastern escarpment and into northern Mozambique.In English "great sable antelope", "sable" or the Swahili name mbarapi are sometimes used. An archaic term used in accounts of hunting expeditions in South Africa is "potaquaine"; the origin and exact application are unclear. Local names include swartwitpens (Afrikaans), kgama or phalafala (Sotho), mBarapi or palahala (Swahili), kukurugu, kwalat or kwalata (Tswana), ngwarati (Shona), iliza (Xhosa),  impalampala (Zulu) and umtshwayeli (Ndebele).
+
+
+== Description ==
+The sable antelope is sexually dimorphic, with the male heavier and about one-fifth taller than the female. The head-and-body length is typically between 190 and 255 cm (75 and 100 in). Males reach about 117–140 cm (46–55 in) at the shoulder, while females are slightly shorter. Males typically weigh 235 kg (518 lb) and females 220 kg (490 lb). The tail is 40–75 cm (16–30 in) long, with a tuft at the end.The sable antelope has a compact and robust build, characterized by a thick neck and tough skin. It has a well-developed and often upright mane on its neck, as well as a short mane on the throat. Its general colouration is rich chestnut to black. Females and juveniles are chestnut to dark brown, while males begin darkening and turn black after three years. However, in southern populations, females have a brown to black coat. Calves less than two months old are a light tan and show faint markings. The underparts, cheek, and chin are all white, creating a great contrast with the dark back and flanks. Long, white hairs are present below the eyes, and a wide, black stripe runs over the nose.Both sexes have ringed horns which arch backwards. In females, these can reach 61–102 cm (24–40 in), while in males they are 81–165 cm (32–65 in) long. The average lifespan of the sable antelope is 19 years in the wild and 22 years in captivity.
+
+		
+
+
+== Behavior ==
+Sable antelopes live in savanna woodlands and grasslands during the dry season, where they eat mid-length grasses and leaves. They visit salt licks and have been known to chew bones to collect minerals. They are diurnal, but are less active during the heat of the day. They form herds of 10 to 30 females and calves led by a single male, called a bull. Males fight among themselves; they drop to their knees and use their horns.In each herd, the juvenile males are exiled from the herd around 3 years old. All of the female calves remain, however. When the herd gets too large, it divides into smaller groups of cows and their young. These groups form new herds, once again with only one adult bull. The young males, which have been separated from the herd, associate in "bachelor groups" of up to 12 individuals. Among the bachelors, the most dominant is the first individual to join a new group of females when the position is open. Seldom, during their fights for dominance, they are able to inflict bodily harm to any contenders.When sable antelopes are threatened by predators, including lions, they confront their attackers and fight-back aggressively. Using their scimitar-shaped horns that can reach to its vulnerable rump area (which is generally preferred by predators), they can impale their enemy. There are instances where their predators have died during such fights. In the 1950 to 1970's the antelope's numbers were reduced severely by tsetse fly pest outbreaks.The grassland habitat of the sable antelope is being reduced by habitat destruction for agricultural development. Sable antelope are important to their habitats as grazers and browsers. They are also important as prey for carnivores.
+
+
+=== Reproduction ===
+The giant sable antelope's breeding season is seasonal and births coincide with the rainy season. After a gestation period of around 9 months, the female gives birth to a single young. A newborn calf is born with a sandy coloured coat, which helps it to camouflage. The calf will lie hidden away for at least 10 days while being nursed by its mother.
+Young sable antelope are weaned at around 8 months and will become sexually mature at between 2 and 3 years. As the calf develops, its coat will darken and it will achieve its status within the herd. The life span of a giant sable antelope is around 17 years.
+
+
+=== Diet ===
+Sable antelopes are herbivores. They are specialized browsing animals that feed upon foliage, mid-length grasses, leaves and herbs, particularly those that grow on termite mounds. Tree leaves make up 90% of their diet. They are diurnal animals, meaning they are most active in the daylight, but less active during the hottest part of the day. Like other bovids, they also have a ruminant digestive system.

+The Philippine sailfin lizard, crested lizard, sail-fin lizard, sailfin water lizard, soa-soa water lizard (Hydrosaurus pustulatus) or its native name ibid is an oviparous lizard endemic to several of the islands that make up the Philippines and is also found in New Guinea and some parts of Eastern Indonesia. The Philippine Sailfin Lizard is a protected species in its native country of the Philippines as it is a target for exotic pet collectors and sought after in the international pet trade. This is largely because these lizards have unique dorsal crests (otherwise known as sailfins) that give the organism a structure similar to a sail, and the Philippine sailfin lizard also has very bright coloration patterns that make them attractive to the eye. The pustulatus species is unique within the Hydrosaurus genus because of the confusion for the past several decades of classifying these organisms amongst other lizards within their same genus in their habitat. They are also very talented swimmers, and smaller juvenile lizards can run on top of water due to their bodily structure. The genus Hydrosaurus means water dragon, which reflects the aforementioned abilities lizards have in water. The Philippine sailfin lizard usually lies close to bodies of water, stays in tree branches, and runs across the ground to get around their habitat. They utilize their sailfins/scales to do territorial displays in the presence of a competitor or a predator. In terms of their reproduction, they utilize sexual reproduction and breed one time each year, but they can produce multiple clutches of eggs with between 2 and 8 eggs. These eggs are buried into the soil for a period of two months before hatchlings are produced. Philippine sailfin lizards are heavily studied by herpetologists and other scientists, as they are unique amongst other reptile lizards with regard to their coloration and form.
+
+
+== History and taxonomy ==
+In 1829, Johann Friedrich von Eschscholtz discovered a new sailfin lizard species in the Philippines and designated it as Hydrosaurus pustulatus. The genus Hydrosaurus is specific to Southeast Asia, and it only contains three major species (with two additional species falling under H. amboinensis): H. amboinensis, H. pulsatus, and H. weberi. The Philippine sailfin lizard and the genus Hydrosaurus is also commonly referred to as a water dragon due to their excellent ability to swim in and sometimes run across water. There have been issues with the taxonomic identification of Hydrosaurus pustulatus because the original descriptions were of immature members of the  species in the 1800’s and were not descriptive enough for diagnostic procedures in environmental studies. As a result, efforts for understanding the spread of different taxonomic groupings have been a challenge.
+
+
+== Habitat and distribution ==
+The Philippine sailfin lizard is found across several of the islands that comprise the Philippines, including Guimaras, Romblon, Negros, and Cebu, but the lizard is not found in Palawan Island. The lizard is also found in New Guinea and some of eastern Indonesia. The Philippine sailfin lizard lives in tropical wooded habitats near water, like rivers, riverbanks, rice-fields and mangrove. The Philippine sailfin lizard also lives in moderately high densities in these habitats. The Philippine sailfin lizard also prefers the bodies of water that they reside nearby being freshwater. Due to confusion with H. amboinensis, the exact distribution in the Philippines has been labelled with some uncertainty. However, a genetic study that sampled individuals throughout the Philippine archipelago (from Mindanao in south to Luzon in north) found that all were H. pustulatus, which is divided into six clades. Additionally, the Philiippine sailfin lizard is often found near rocky areas close to a stream.
+
+
+== Behavior and appearance ==
+In terms of the physical characteristics, Philippine sailfin lizards are large and usually grow to a length between two and three feet, including its tail, but males are larger than females and can grow up to between 3 and 4 feet long (91 - 120 centimeters). These lizards typically weigh between 3 and 5 pounds (1.4 - 2.3 kg). Additionally, this species of lizard has a unique characteristic being its crest or sailfin, which is an upright part of its body that occurs from the base of the tail to the lower area of the back. This crest or sailfin is used not only to help with its ability to swim efficiently in water, but is also thought to assist with the lizard's ability to do territorial displays and heat/cool in different environments. The crest also makes the Philippine sailfin lizard’s body look like a sail with regard to its structure. Overall, the body and tail of the Philippine sailfin lizard is largely cylindrical.  The juvenile Philippine sailfin lizard is an excellent swimmer and has flattened toes along with smaller mass compared to adults that enable it to run across water, similar to the basilisks. The adult Philippine sailfin lizard does not usually retain a smaller mass and loses the ability to run across water, but it uses these flattened toes to swim very effectively. The flattened toes also have scale fringes that can be used for swimming and running on top of water as mentioned before. Males have a larger crest on their back than the females. The males also have bigger heads, taller sails on their tails, and darker limbs. During mating season, the head of the Philippine sailfin lizard becomes violet while only the neck area of a female’s crest can become violet. In terms of coloration, Philippine sailfin lizards have dark green and brown skin, and can also have yellow patches on the back side of their body and near their heads. The Philippine sailfin lizard has a flattened tail that is used to propel in water more quickly, adding to its natural born ability to be agile and swift in water to evade prey. In the presence of predators, the Philippine sailfin lizard either drops from the tree branch it is residing on, runs, or swims to the bottom of the body of water it is closest to and can hold its breath for up to 15 minutes. Philippine sailfin lizards are also diurnal and spend most of the day time resting in vegetation out in the sun. In general, the Philippine sailfin lizard utilizes running to move around its habitats and away or toward predators and competitors, and their lifespan can be anywhere between 10 and 20 years. The Philippine sailfin lizard also has a unique physical feature being a vestigial eye (which is also known as parietal or pineal eye) on the top of the lizard's skull that can detect differing angles of light from the sun and is thought to be used to find a sense of direction.
+
+
+== Life cycle and reproduction ==
+Philippine sailfin lizards reproduce through sexual reproduction, and they only breed once every year with potentially multiple clutches of eggs. In order for female Philippine sailfin lizards to lay their eggs after mating and birth, they dig relatively shallow holes in soil near their watery-habitats, and these eggs then incubate for approximately two months. The eggs then eventually become hatchlings during the rainy season, which actually are born with a natural swiftness and agility that allows them to evade their predators by running across the water unlike adult lizards that swim. These female Philippine sailfin lizards are able to lay several clutches of eggs a year that each can contain anywhere between 2 and 8 eggs. It's also important to note that these eggs are laid above the flood line.
+
+
+== Conservation ==
+Philippine sailfin lizards have now been classified as vulnerable by the IUCN. Their main threats are habitat loss, being hunted for food, and collection for the pet trade. The factors contributing to this vulnerable conservation status include habitat loss, hunting by exotic meat collectors and the pet trade. It is currently illegal according to Philippine law to export the lizard out of the country, but some exotic pet collectors claim to already be in possession of these lizards and breed them in captivity to sell them to buyers in the United States of America. In fact, the median price for these lizards is $700, which is considerably more expensive than other lizards. Some of the most well known trading centers for the Philippine sailfin lizards are 1) Puerto Princesa City, Palawan Island, 2) Cebu City, Cebu Island, and 3) Davao City, Mindanao Island. It’s essential that conservation efforts to create protected areas within the Philippines for the Philippine sailfin lizard are within the habitats that they normally live in and not these trading areas. In terms of the history of the pet trade, Philippine sailfin lizards were sold in higher frequency between  1980 and 1990 because the Philippines as a country was exporting them internationally, but they now do not export these lizards anymore, leaving Indonesia to be the primary source of exporting them.
+
+
+== Diet ==
+The Philippine sailfin lizards are omnivores and they eat plants including leaves and fruits in addition to insects and crustaceans. Juvenile Philippine sailfin lizards start out preferring meat more than plants, but the balance comes as they age. Their diet is easy to replicate, which is why they are a target for exotic pet collectors, but they’re not as docile compared to other lizards. The Philippine sailfin lizard’s omnivorous diet is also reflected by its relatively simple dental complexity, specifically with the posterior teeth of the mouth having less defined tricuspid teeth and the posterior teeth being tricuspid. As a result, the lizard cannot primarily be a carnivore since its teeth were not designed to do so.
+
+
+== In captivity ==
+In terms of keeping a Philippine sailfin lizard in captivity, they are typically kept in large enclosures with tropical-styled heating, semi-arboreal resources, access to submerging in water to mimic their natural environment. Breeding in captivity has only been done in a few cases, but this explanation has also been used as a method of smuggling the Philippine sailfin lizards out of their native habitats for sale. Since it is common in many parts of the Philippines, the pet trade in many regions still continues and some are even unrecognized by the government. It’s also important to note that the Philippine sailfin lizards are to be approached with caution when held captive as they are extremely nervous and can scratch people, but studies have shown that hand-feeding these lizards helps them become less nervous and gain trust.

+The lar gibbon (Hylobates lar), also known as the white-handed gibbon, is an endangered primate in the gibbon family, Hylobatidae. It is one of the better-known gibbons and is often kept in captivity.
+
+
+== Taxonomy ==
+There are five subspecies of lar gibbon:
+Malaysian lar gibbon (H. l. lar)
+Carpenter's lar gibbon (H. l. carpenteri)
+Central lar gibbon (H. l. entelloides)
+Sumatran lar gibbon (H. l. vestitus)
+Yunnan lar gibbon (H. l. yunnanensis) (possibly extinct)
+
+
+== Physical description ==
+
+The fur coloring of the lar gibbon varies from black and dark-brown to light-brown, sandy colors. The hands and feet are white-colored, likewise a ring of white hair surrounds the black face. Both males and females can be all color variants, and the sexes also hardly differ in size.  Gibbons are true brachiators, propelling themselves through the forest by swinging under the branches using their arms.  Reflecting this mode of locomotion, the white-handed gibbon has curved fingers, elongated hands, extremely long arms and relatively short legs, giving it an intermembral index of 129.7, one of the highest of the primates.  As with all apes, the number of caudal vertebrae has been reduced drastically, resulting in the loss of a functional tail. Gibbons have tough, bony padding on their buttocks, known as the ischial callosities, or sitting pads.
+
+
+== Distribution and habitat ==
+
+Lar gibbons have the greatest north-south range of any of the gibbon species.  They are found in Indonesia, Laos, Malaysia, Myanmar and Thailand. Their range historically extended from southwest China to Thailand and Burma south to the whole Malay Peninsula in primary and secondary tropical rain forests.  It is also present in the northwest portion of the island of Sumatra. In recent decades, especially, the continental range has been reduced and fragmented. Lar gibbons are likely extinct in China, but if they still exist, they would only be found in southwest Yunnan, their former range.Lar gibbon are usually found in lowland dipterocarp forest, hill dipterocarp forest, and upper dipterocarp forest, including primary lowland and submontane rainforest, mixed deciduous bamboo forest, and seasonal evergreen forest. They are not usually found higher than 1200 meters above sea level. 
+The gibbon genus is highly allopatric, usually separated by large rivers. As a result, their range extends through southern and eastern Myanmar, but only east of the Salween River. They are found through the Malay Peninsula. Lar gibbons also exist west of the Mekong River in northwestern Laos and northern Sumatra.
+The lar gibbon can be found living in sympatry with several other primates and apes, including orangutans (Pongo pygmaeus), siamangs (S. syndactylus), pileated gibbons (Hylobates pileatus), purple-faced langurs (Trachypithecus spp.), Thomas's langur (Presbytis thomasi), slow loris (Nycticebus coucang), and several macaques (Macaca spp.) 
+In Thailand, lar gibbons probably number between 15,000 and 20,000, though there may be as few as 10 in China, if any.
+
+
+== Diet and dentition ==
+
+The lar gibbon is considered frugivorous with fruit constituting 50% of its diet, but leaves (29%) are a substantial part, with insects (13%) and flowers (9%) forming the remainder. In the wild, lar gibbons will eat a large variety of foods, including figs and other small, sweet fruits, liana fruit, tree fruit and berries, as well as young leaves, buds and flowers, new shoots, vines, vine shoots, and insects, including mantids and wasps, and even birds' eggs.  During the summer months, when figs and leaves are less available, insect consumption increases twenty-fold relative to the winter.Its dental formula is 2.1.2.32.1.2.3, the generalized formula for Old World monkeys and apes (including humans).  The dental arcade is U-shaped, and the mandible is thin and light.  The incisors are broad and flat, while the molars have low, rounded cusps with thick enamel.  The most noticeable characteristic of the dentition of Hylobates lar is the presence of large, dagger-like canines in both the upper and lower jaw.  These canines are not sexually dimorphic.
+
+
+== Behavior ==
+
+Lar gibbons are diurnal and arboreal, inhabiting rain forests. Lar gibbons are usually active for an average of 8.7 hours per day, leaving their sleeping sites right around sunrise and entering sleeping trees an average of 3.4 hours before sunset. 
+On average, lar gibbons spend their days feeding (32.6%), resting (26.2%), traveling (24.2%), in social activities (11.3%), vocalizing (4.0%) and in intergroup encounters (1.9%), although actual proportions of activities can change significantly over the course of the year. They rarely come to the ground, instead using their long arms to brachiate through the trees. With their hooked hands, they can move swiftly with great momentum, swinging from the branches.  Although they rarely come to the ground naturally, while there, they walk  bipedally with arms raised above their heads for balance. Their social organization is dominated by monogamous family pairs, with one breeding male and one female along with their offspring.  When a juvenile reaches sexual maturity, it is expelled from the family unit.  However, this traditional conception has come under scrutiny.  Long-term studies conducted in Khao Yai National Park in Thailand suggest their mating system is somewhat flexible, incorporating extra-pair copulations, partner changes and polyandrous groupings. This multimale polyandry may be attributed to cooperative territory use and female defense. As range size increases, males are more successful in defending it in a pair or group. Additionally, these extra pair copulations may increase the chance of reproduction with a mate of superior genetic quality and decrease the chance of infanticide.
+
+
+=== Vocalisations ===
+
+Family groups inhabit a firm territory, which they protect by warding off other gibbons with their calls.  Each morning, the family gathers on the edge of its territory and begins a "great call", a duet between the breeding pair.  Each species has a typified call and each breeding pair has unique variations on that theme.  The great call of Hylobates lar is characterized by its frequent use of short hoots with more complex hoots, along with a "quavering" opening and closing.  These calls are one of the traits used determining species differences among the gibbons. Recent studies indicate that gibbon song have evolved to communicate conflict in terms of predation. In the presence of tiger, clouded leopard, crested serpent eagle and reticulated python songs were more likely to contain sharp wow elements than normal duets.
+
+
+=== Reproduction ===
+
+Sexually, they are similar to other gibbons. Mating occurs in every month of the year, but most conceptions occur during the dry season in March, with a peak in births during the late rainy season, in October. On average, females reproduce for the first time at about 11 years of age in the wild, much later than in captivity. Gestation is six months long on average, and pregnancies are usually of a single young. Young are nursed for approximately two years, and full maturity comes at about eight years. The life expectancy of the lar gibbons in the wild is about 25 years.
+
+
+== Conservation ==
+
+Lar gibbons are threatened in various ways: they are sometimes hunted for their meat, sometimes a parent is killed to capture young animals for pets, but perhaps the most pervasive is the loss of habitat. Lar gibbon habitats are already threatened by forest clearance for the construction of roads, agriculture, ecotourism, domesticated cattle and elephants, forest fires, subsistence logging, illegal logging, new village settlement, and palm oil plantations.

+Iguana (, Spanish: [iˈɣwana]) is a genus of herbivorous lizards that are native to tropical areas of Mexico, Central America, South America, and the Caribbean. The genus was first described in 1768 by Austrian naturalist Josephus Nicolaus Laurenti in his book Specimen Medicum, Exhibens Synopsin Reptilium Emendatam cum Experimentis circa Venena. Two species are placed in the genus, the green iguana, which is widespread throughout its range and a popular pet, and the Lesser Antillean iguana, which is native to the Lesser Antilles. Genetic analysis indicates that the green iguana may comprise a complex of multiple species, some of which have been recently described, but the Reptile Database considers all of these as subspecies of the green iguana.The word "iguana" is derived from the original Taino name for the species, iwana.
+In addition to the two species in the genus Iguana, several other related genera in the same family have common names of the species including the word "iguana".The species is a popular quarry for pets, and has been widely introduced beyond its native area, into Ishigaki Island, Florida Peninsula, Hawaii, numerous islands in the Lesser Antilles, Singapore, Thailand, and Taiwan.
+
+
+== Anatomy and physiology ==
+Iguanas can range from 1.5 to 1.8 m (5 to 6 ft) in length, including their tails. These lizards possess a dewlap and a row of elongated scales running from the midline of their necks down to their tails. Iguanas have varying types of scales covering different areas of their body, for example,  some large, round tuberculate scales are scattered around the lateral region of the neck among smaller, overlapping scales. The scales on the dorsal trunk of their bodies are also thicker and more tightly packed than those on the ventral sides. These scales may be a variety of colors and are not always visible from close distances. They have a large, round scale on their cheeks known as a subtympanic shield.Iguanas have keen vision and can see shapes, shadows, colors, and movement at long distances. Their visual acuity enables them to navigate through crowded forests and to locate food. They employ visual signals to communicate with other members of the same species.The tympanum, the iguana's eardrum, is located above the subtympanic shield (or "ear shield") behind each eye.
+Iguanas are often hard to spot, as they tend to blend into their surroundings, and their coloration enables them to hide from larger predators.Like most reptiles, an iguana has a three-chambered heart with two atria, one ventricle, and two aortae with a systemic circulation.
+The muscles of an iguana are very light in color due to the high proportion of fast-twitch, glycolytic muscle fibers (type A). These A fibers are not very vascularized and are low in myoglobin, giving them their pale look. This high density of A fibers allows iguanas to move very quickly for a short period of time, which facilitates short bursts of movement, but is inefficient for long duration movement, since cellular respiration in A fibers is anaerobic.
+
+
+=== Parietal eye ===
+Several species of lizards, including the iguanas, have a pale scale towards the back of their heads marking the parietal eye. This organ is sensitive to changes in illumination and sends signals to the pineal gland noting the change between day and night. A photopigment commonly found in the lamprey, known as parapinopsin, is also found in the iguana, and is sensitive to ultraviolet light and aids in the signaling between day and night.
+
+
+=== Skull morphology and diet ===
+
+Iguanas have developed an herbivorous lifestyle, foraging exclusively on vegetation and foliage. To acquire, process, and digest plant matter, herbivorous lizards must have a higher bite force relative to their size in comparison to carnivorous or omnivorous reptiles. The skull of the iguana has undergone modifications resulting in a strong bite force and efficient processing of vegetation, according to one study.  To accomplish this biomechanically, herbivorous lizards  have taller and wider skulls, shorter snouts, and larger bodies relative to carnivorous and omnivorous reptiles.  Increasing the strength of the skull allows for increased muscle presence and increases the ability of the skull to withstand stronger forces.
+
+Furthermore, the teeth of the iguana are acrodontal, meaning that their teeth sit on top of the surface of the jaw bone and project upwards. The teeth themselves are small and serrated - designed to grasp and shear food.
+
+
+=== Reproduction ===
+Male iguanas, like other male examples of Squamata, have two hemipenes. During copulation, one hemipenis is inserted into the female's cloacal vent. A female can store sperm from previous mates for several years to continue to fertilize her eggs in case she finds no male within her territory when she is ready to lay again.
+
+
+=== Mating/courtship ===
+Iguanas tend to follow a promiscuous or polygynadrous mating style during the dry season. Mating during the dry season ensures that their offspring will hatch during the wet or rainy season when food will be more plentiful. Females control large territories, where they make several nests. Males compete for the females in an area and mark their won territory with a pheromone secreted from the femoral pores on the dorsal side of their hind limbs. Male behavior during sexual competition involves head bobbing, extending and retracting their dewlap, nuzzling and biting the necks of females, and on occasion, changing color. Once a female chooses a male, he straddles the female and holds her in place by biting onto her shoulder, which sometimes leaves scars on females. After copulation, eggs are laid within several nests and allowed to incubate. This low level of parental intervention with their offspring makes iguanas an example of r-strategy reproduction.
+
+
+== Phylogeny ==
+A phylogeny based on nuclear protein-coding genes, reviewed by Vidal and Hedges (2009), suggested that the subclade Iguania is in a group with snakes and anguimorphs (lizards). These groups share an oral gland capable of secreting toxins (a derived trait). The phylogeny based on whole mitochondrial genomes, though, as proposed by Rest et al. (2003), places the green iguana as the closest relative of the mole skink (Plestiodon egregius). Lepidosaurs are reptiles with overlapping scales, and within this group both iguanians and tuataras (Sphenodon) project their tongues to seize prey items instead of using their jaws, which is called tongue prehension. Iguanians are the only lineage within the Squamata that display this trait, meaning that it was gained independently in both iguanians and tuataras. Iguanians are also the only squamates that primarily use their sight to identify and track prey rather than chemoreception or scent, and employ an ambush technique of catching prey instead of active searching.A study by Breuil et al. (2020) found the taxonomy of the genus Iguana as follows, with I. delicatissima being the most basal member of the group. The species are classified as subspecies based on the ReptileDatabase definitions.
+
+The Reptile Database synonymizes I. rhinolopha with I. iguana, only considering it a distinctive population, and recognizes I. insularis and I. melanoderma as subspecies of I. iguana. Four subspecies of green iguana are recognized under this treatment: I. i. insularis (Saint Vincent & the Grenadines and Grenada), I. i. sanctaluciae (Saint Lucia), I. i. melanoderma (parts of the northern Lesser Antilles, and potentially coastal Venezuela, the Virgin Islands, and Puerto Rico), and I. i. iguana (mainland South America).
+
+
+=== Extant species ===
+Two extant species in the genus Iguana are widely recognized.
+
+
+==== Subspecies ====
+Three Caribbean subspecies of the green iguana are also recognized:
+
+The Central American iguana (I. rhinolopha or I. i. rhinolopha), sometimes considered a distinct species, is largely considered synonymous with I. iguana, as the presence of horns does not necessarily indicate a new species or subspecies. The two described subspecies of I. insularis (the Saint Lucia horned iguana, I. i. sanctaluciae, and the Grenadines horned iguana, I. i. insularis) were originally described as subspecies of I. iguana, although they are genetically very similar and may not be separate subspecies from one another. Recent studies have recovered I. rhinolopha and I. insularis as distinct species based on genetics, but the Reptile  Database disagrees with these conclusions, and classifies I. rhinolopha as synonymous with I. iguana, and I. insularis as a subspecies of I. iguana. The Curaçao population of green iguanas shows major genetic divergence and may also represent an as-of-yet undescribed species or subspecies.
+
+
+== As food ==
+
+Iguanas have historically featured in the culinary traditions of Mexico and Central America. Iguana meat is also consumed in parts of the United States and Puerto Rico.
+Also, the eggs of iguana are consumed in some parts of Latin America, such as Nicaragua and Colombia.

+The jaguar (Panthera onca) is a large cat species and the only living member of the genus Panthera native to the Americas. With a body length of up to 1.85 m (6 ft 1 in) and a weight of up to 158 kg (348 lb), it is the largest cat species in the Americas and the third largest in the world. Its distinctively marked coat features pale yellow to tan colored fur covered by spots that transition to rosettes on the sides, although a melanistic black coat appears in some individuals. The jaguar's powerful bite allows it to pierce the carapaces of turtles and tortoises, and to employ an unusual killing method: it bites directly through the skull of mammalian prey between the ears to deliver a fatal blow to the brain.
+The modern jaguar's ancestors probably entered the Americas from Eurasia during the Early Pleistocene via the land bridge that once spanned the Bering Strait. Today, the jaguar's range extends from core Southwestern United States across Mexico and much of Central America, the Amazon rainforest and south to Paraguay and northern Argentina. It inhabits a variety of forested and open terrains, but its preferred habitat is tropical and subtropical moist broadleaf forest, wetlands and wooded regions. It is adept at swimming and is largely a solitary, opportunistic, stalk-and-ambush apex predator. As a keystone species, it plays an important role in stabilizing ecosystems and in regulating prey populations.
+The jaguar is threatened by habitat loss, habitat fragmentation, poaching for trade with its body parts and killings in human–wildlife conflict situations, particularly with ranchers in Central and South America. It has been listed as Near Threatened on the IUCN Red List since 2002. The wild population is thought to have declined since the late 1990s. Priority areas for jaguar conservation comprise 51 Jaguar Conservation Units (JCUs), defined as large areas inhabited by at least 50 breeding jaguars. The JCUs are located in 36 geographic regions ranging from Mexico to Argentina.
+The jaguar has featured prominently in the mythology of indigenous peoples of the Americas, including those of the Aztec and Maya civilizations.
+
+
+== Etymology ==
+The word "jaguar" is possibly derived from the Tupi-Guarani word yaguara meaning 'wild beast that overcomes its prey at a bound'. In North America, the word is pronounced disyllabic , while in British English, it is pronounced with three syllables . Indigenous peoples in Guyana call it jaguareté.
+"Onca" is derived from the Portuguese name onça for a spotted cat in Brazil that is larger than a lynx; cf. ounce. The word "panther" is derived from classical Latin panthēra, itself from the ancient Greek πάνθηρ (pánthēr).
+
+
+== Taxonomy and evolution ==
+
+
+=== Taxonomy ===
+In 1758, Carl Linnaeus described the jaguar in his work Systema Naturae and gave it the scientific name Felis onca.
+In the 19th and 20th centuries, several jaguar type specimens formed the basis for descriptions of subspecies. In 1939, Reginald Innes Pocock recognized eight subspecies based on the geographic origins and skull morphology of these specimens.
+Pocock did not have access to sufficient zoological specimens to critically evaluate their subspecific status but expressed doubt about the status of several. Later consideration of his work suggested only three subspecies should be recognized. The description of P. o. palustris was based on a fossil skull.
+By 2005, nine subspecies were considered to be valid taxa.
+Reginald Innes Pocock placed the jaguar in the genus Panthera and observed that it shares several morphological features with the leopard (P. pardus). He, therefore, concluded that they are most closely related to each other. Results of morphological and genetic research indicate a clinal north–south variation between populations, but no evidence for subspecific differentiation. DNA analysis of 84 jaguar samples from South America revealed that the gene flow between jaguar populations in Colombia was high in the past. Since 2017, the jaguar is considered to be a monotypic taxon.
+
+
+=== Evolution ===
+
+The Panthera lineage is estimated to have genetically diverged from the common ancestor of the Felidae around 9.32 to 4.47 million years ago to 11.75 to 0.97 million years ago,
+and the geographic origin of the genus is most likely northern Central Asia.
+Some genetic analyses place the jaguar as a sister species to the lion with which it diverged 3.46 to 1.22 million years ago, but other studies place the lion closer to the leopard.The lineage of the jaguar appears to have originated in Africa and spread to Eurasia 1.95–1.77 mya. The modern species may have descended from Panthera gombaszoegensis, which is thought to have entered the American continent via Beringia, the land bridge that once spanned the Bering Strait. Fossils of modern jaguars have been found in North America dating to over 850,000 years ago. Results of mitochondrial DNA analysis of 37 jaguars indicate that current populations evolved between 510,000 and 280,000 years ago in northern South America and subsequently recolonized North and Central America after the extinction of jaguars there during the Late Pleistocene.Two extinct subspecies of jaguar are recognized in the fossil record: the North American P. o. augusta and South American P. o. mesembrina.
+
+
+== Description ==
+
+The jaguar is a compact and well-muscled animal. It is the largest cat native to the Americas and the third largest in the world, exceeded in size only by the tiger and the lion. It stands 68 to 75 cm (26.8 to 29.5 in) tall at the shoulders.
+Its size and weight vary considerably: weights are normally in the range of 56–96 kg (123–212 lb). Exceptionally big males have been recorded to weigh as much as 158 kg (348 lb).
+The smallest females weigh about 36 kg (79 lb). It is sexually dimorphic, with females typically being 10–20% smaller than males. The length from the nose to the base of the tail varies from 1.12 to 1.85 m (3 ft 8 in to 6 ft 1 in). The tail is 45 to 75 cm (18 to 30 in) long and the shortest of any big cat.
+Its muscular legs are shorter than the legs of other Panthera species with similar body weight.Further variations in size have been observed across regions and habitats, with size tending to increase from north to south. Jaguars in the Chamela-Cuixmala Biosphere Reserve on the Pacific coast of central Mexico weighed around 50 kg (110 lb), which is about the size of a female cougar (Puma concolor).
+Jaguars in Venezuela and Brazil are much larger, with average weights of about 95 kg (209 lb) in males and of about 56–78 kg (123–172 lb) in females.The jaguar's coat ranges from pale yellow to tan or reddish-yellow, with a whitish underside and covered in black spots. The spots and their shapes vary: on the sides, they become rosettes which may include one or several dots. The spots on the head and neck are generally solid, as are those on the tail where they may merge to form bands near the end and create a black tip. They are elongated on the middle of the back, often connecting to create a median stripe, and blotchy on the belly. These patterns serve as camouflage in areas with dense vegetation and patchy shadows.
+Jaguars living in forests are often darker and considerably smaller than those living in open areas, possibly due to the smaller numbers of large, herbivorous prey in forest areas.The jaguar closely resembles the leopard but is generally more robust, with stockier limbs and a more square head. The rosettes on a jaguar's coat are larger, darker, fewer in number and have thicker lines, with a small spot in the middle.
+It has powerful jaws with the third-highest bite force of all felids, after the tiger and the lion.
+It has an average bite force at the canine tip of 887.0 Newton and a bite force quotient at the canine tip of 118.6.
+A 100 kg (220 lb) jaguar can bite with a force of 4.939 kN (1,110 lbf) with the canine teeth and 6.922 kN (1,556 lbf) at the carnassial notch.
+
+
+=== Color variation ===
+Melanistic jaguars are also known as black panthers. The black morph is less common than the spotted one.
+Black jaguars have been documented in Central and South America. Melanism in the jaguar is caused by deletions in the melanocortin 1 receptor gene and inherited through a dominant allele.In 2004, a camera trap in the Sierra Madre Occidental mountains photographed the first documented black jaguar in Northern Mexico. Black jaguars were also photographed in Costa Rica's Alberto Manuel Brenes Biological Reserve, in the mountains of the Cordillera de Talamanca, in Barbilla National Park and in eastern Panama.
+
+
+== Distribution and habitat ==
+
+In the 19th century, the jaguar was still sighted at the North Platte River in Colorado and coastal Louisiana.
+In 1919, sightings of jaguars were reported in the Monterey, California region.
+In 1999, its historic range at the turn of the 20th century was estimated at 19,000,000 km2 (7,300,000 sq mi), stretching from the southern United States through Central America to southern Argentina. By the turn of the 21st century, its global range had decreased to about 8,750,000 km2 (3,380,000 sq mi), with most declines in the southern United States, northern Mexico, northern Brazil, and southern Argentina.
+Its present range extends from Mexico through Central America to South America comprising Belize, Guatemala, Honduras, Nicaragua, Costa Rica, particularly on the Osa Peninsula, Panama, Colombia, Venezuela, Guyana, Suriname, French Guiana, Ecuador, Peru, Bolivia, Brazil, Paraguay and Argentina. It is considered to be locally extinct in El Salvador and Uruguay.Jaguars have been occasionally sighted in Arizona, New Mexico and Texas.
+Between 2012 and 2015, a male vagrant jaguar was recorded in 23 locations in the Santa Rita Mountains.The jaguar prefers dense forest and typically inhabits dry deciduous forests, tropical and subtropical moist broadleaf forests, rainforests and cloud forests in Central and South America; open, seasonally flooded wetlands, dry grassland and historically also oak forests in the United States. It has been recorded at elevations up to 3,800 m (12,500 ft) but avoids montane forests. It favors riverine habitat and swamps with dense vegetation cover. In the Mayan forests of Mexico and Guatemala, 11 GPS-collared jaguars preferred undisturbed dense habitat away from roads; females avoided even areas with low levels of human activity, whereas males appeared less disturbed by human population density. A young male jaguar was also recorded in the semi-arid Sierra de San Carlos at a waterhole.
+
+
+== Behavior and ecology ==
+The jaguar is mostly active at night and during twilight.
+However, jaguars living in densely forested regions of the Amazon Rainforest and the Pantanal are largely active by day, whereas jaguars in the Atlantic Forest are primarily active by night.
+The activity pattern of the jaguar coincides with the activity of its main prey species. Jaguars are good swimmers and play and hunt in the water, possibly more than tigers. They have been recorded moving between islands and the shore. Jaguars are also good at climbing trees but do so less often than cougars.
+
+
+=== Ecological role ===
+
+The adult jaguar is an apex predator, meaning it is at the top of the food chain and is not preyed upon in the wild. The jaguar has also been termed a keystone species, as it is assumed that it controls the population levels of prey such as herbivorous and seed-eating mammals and thus maintains the structural integrity of forest systems.
+However, field work has shown this may be natural variability, and the population increases may not be sustained. Thus, the keystone predator hypothesis is not accepted by all scientists.The jaguar is sympatric with the cougar (Puma concolor). In central Mexico, both prey on white-tailed deer (Odocoileus virginianus), which makes up 54% and 66% of jaguar and cougar's prey, respectively. In northern Mexico, the jaguar and the cougar share the same habitat, and their diet overlaps dependent on prey availability. Jaguars seemed to prefer deer and calves. In Mexico and Central America, neither of the two cats are considered to be the dominant predator.
+In South America, the jaguar is larger than the cougar and tends to take larger prey, usually over 22 kg (49 lb). The cougar's prey usually weighs between 2 and 22 kg (4 and 49 lb), which is thought to be the reason for its smaller size.
+This situation may be advantageous to the cougar. Its broader prey niche, including its ability to take smaller prey, may give it an advantage over the jaguar in human-altered landscapes.
+
+
+=== Hunting and diet ===
+
+The jaguar is an obligate carnivore and depends solely on flesh for its nutrient requirements. An analysis of 53 studies documenting the diet of the jaguar revealed that its prey ranges in weight from 1 to 130 kg (2.2 to 286.6 lb); it prefers prey weighing 45–85 kg (99–187 lb), with capybara (Hydrochoerus hydrochaeris) and giant anteater (Myrmecophaga tridactyla) being the most selected. When available, it also preys on marsh deer (Blastocerus dichotomus), southern tamandua (Tamandua tetradactyla), collared peccary (Dicotyles tajacu) and black agouti (Dasyprocta fuliginosa). In floodplains, jaguars opportunistically take reptiles such as turtles and caimans. Consumption of reptiles appears to be more frequent in jaguars than in other big cats. One remote population in the Brazilian Pantanal is recorded to primarily feed on aquatic reptiles and fish.
+The jaguar also preys on livestock in cattle ranching areas where wild prey is scarce.
+The daily food requirement of a captive jaguar weighing 34 kg (75 lb) was estimated at 1.4 kg (3.1 lb) of meat.The jaguar's bite force allows it to pierce the carapaces of the yellow-spotted Amazon river turtle (Podocnemis unifilis) and the yellow-footed tortoise (Chelonoidis denticulatus). It employs an unusual killing method: it bites mammalian prey directly through the skull between the ears to deliver a fatal bite to the brain. It kills capybara by piercing its canine teeth through the temporal bones of its skull, breaking its zygomatic arch and mandible and penetrating its brain, often through the ears.
+It has been hypothesized to be an adaptation to "cracking open" turtle shells; armored reptiles may have formed an abundant prey base for the jaguar following the late Pleistocene extinctions. However, this is disputed, as even in areas where jaguars prey on reptiles, they are still taken relatively infrequently compared to mammals in spite of their greater abundance.Between October 2001 and April 2004, 10 jaguars were monitored in the southern Pantanal. In the dry season from April to September, they killed prey at intervals ranging from one to seven days; and ranging from one to 16 days in the wet season from October to March.The jaguar uses a stalk-and-ambush strategy when hunting rather than chasing prey. The cat will slowly walk down forest paths, listening for and stalking prey before rushing or ambushing. The jaguar attacks from cover and usually from a target's blind spot with a quick pounce; the species' ambushing abilities are considered nearly peerless in the animal kingdom by both indigenous people and field researchers and are probably a product of its role as an apex predator in several different environments. The ambush may include leaping into water after prey, as a jaguar is quite capable of carrying a large kill while swimming; its strength is such that carcasses as large as a heifer can be hauled up a tree to avoid flood levels. After killing prey, the jaguar will drag the carcass to a thicket or other secluded spot. It begins eating at the neck and chest. The heart and lungs are consumed, followed by the shoulders.
+
+
+=== Social activity ===
+
+The jaguar is generally solitary except for females with cubs. In 1977, groups consisting of a male, female and cubs, and two females with two males were sighted several times in a study area in the Paraguay River valley. A radio-collared female moved in a home range of 25–38 km2 (9.7–14.7 sq mi), which partly overlapped with another female. The home range of the male in this study area overlapped with several females.The jaguar uses scrape marks, urine, and feces to mark its territory.
+The size of home ranges depends on the level of deforestation and human population density. The home ranges of females vary from 15.3 km2 (5.9 sq mi) in the Pantanal to 53.6 km2 (20.7 sq mi) in the Amazon to 233.5 km2 (90.2 sq mi) in the Atlantic Forest. Male jaguar home ranges vary from 25 km2 (9.7 sq mi) in the Pantanal to 180.3 km2 (69.6 sq mi) in the Amazon to 591.4 km2 (228.3 sq mi) in the Atlantic Forest and 807.4 km2 (311.7 sq mi) in the Cerrado.
+Studies employing GPS telemetry in 2003 and 2004 found densities of only six to seven jaguars per 100 km2 in the Pantanal region, compared with 10 to 11 using traditional methods; this suggests the widely used sampling methods may inflate the actual numbers of individuals in a sampling area. Fights between males occur but are rare, and avoidance behavior has been observed in the wild. In one wetland population with degraded territorial boundaries and more social proximity, adults of the same sex are more tolerant of each other and engage in more friendly and co-operative interactions.
+
+The jaguar roars or grunts for long-distance communication; intensive bouts of counter-calling between individuals have been observed in the wild. This vocalization is described as "hoarse" with five or six guttural notes. Chuffing is produced by individuals when greeting, during courting, or by a mother comforting her cubs. This sound is described as low intensity snorts, possibly intended to signal tranquility and passivity. Cubs have been recorded bleating, gurgling and mewing.
+
+
+=== Reproduction and life cycle ===
+
+In captivity, the female jaguar is recorded to reach sexual maturity at the age of about 2.5 years. Estrus lasts 7–15 days with an estrus cycle of 41.8 to 52.6 days. During estrus, she exhibits increased restlessness with rolling and prolonged vocalizations.
+She is an induced ovulator but can also ovulate spontaneously.Gestation lasts 91 to 111 days.
+The male is sexually mature at the age of three to four years.
+His mean ejaculate volume is 8.6±1.3 ml.Generation length of the jaguar is 9.8 years.In the Pantanal, breeding pairs were observed to stay together for up to five days. Females had one to two cubs.
+The young are born with closed eyes but open them after two weeks. Cubs are weaned at the age of three months but remain in the birth den for six months before leaving to accompany their mother on hunts.
+Jaguars remain with their mothers for up to two years. They appear to rarely live beyond 11 years, but captive individuals may live 22 years.In 2001, a male jaguar killed and partially consumed two cubs in Emas National Park. DNA paternity testing of blood samples revealed that the male was the father of the cubs. Two more cases of infanticide were documented in the northern Pantanal in 2013. Infanticide may be combated by the female hiding her cubs and distracting the male with courtship behavior.
+
+
+=== Attacks on humans ===
+
+The Spanish conquistadors feared the jaguar. According to Charles Darwin, the indigenous peoples of South America stated that people did not need to fear the jaguar as long as capybaras were abundant.
+The first official record of a jaguar killing a human in Brazil dates to June 2008.
+Two children were attacked by jaguars in Guyana.
+The jaguar is the least likely of all big cats to kill and eat humans, and the majority of attacks come when it has been cornered or wounded.
+
+
+== Threats ==
+
+The jaguar is threatened by loss and fragmentation of habitat, illegal killing in retaliation for livestock depredation and for illegal trade in jaguar body parts. It is listed as Near Threatened on the IUCN Red List since 2002, as the jaguar population has probably declined by 20–25% since the mid-1990s. Deforestation is a major threat to the jaguar across its range. Habitat loss was most rapid in drier regions such as the Argentine pampas, the arid grasslands of Mexico and the southwestern United States.In 2002, it was estimated that the range of the jaguar had declined to about 46% of its range in the early 20th century. In 2018, it was estimated that its range had declined by 55% in the last century. The only remaining stronghold is the Amazon rainforest, a region that is rapidly being fragmented by deforestation.
+Between 2000 and 2012, forest loss in the jaguar range amounted to 83.759 km2 (32.340 sq mi), with fragmentation increasing in particular in corridors between Jaguar Conservation Units (JCUs).
+By 2014, direct linkages between two JCUs in Bolivia were lost, and two JCUs in northern Argentina became completely isolated due to deforestation.In Mexico, the jaguar is primarily threatened by poaching. Its habitat is fragmented in northern Mexico, in the Gulf of Mexico and the Yucatán Peninsula, caused by changes in land use, construction of roads and tourism infrastructure.
+In Panama, 220 of 230 jaguars were killed in retaliation for predation on livestock between 1998 and 2014.
+In Venezuela, the jaguar was extirpated in about 26% of its range in the country since 1940, mostly in dry savannas and unproductive scrubland in the northeastern region of Anzoátegui.
+In Ecuador, the jaguar is threatened by reduced prey availability in areas where the expansion of the road network facilitated access of human hunters to forests.
+In the Alto Paraná Atlantic forests, at least 117 jaguars were killed in Iguaçu National Park and the adjacent Misiones Province between 1995 and 2008.
+Some Afro-Colombians in the Colombian Chocó Department hunt jaguars for consumption and sale of meat.
+Between 2008 and 2012, at least 15 jaguars were killed by livestock farmers in central Belize.The international trade of jaguar skins boomed between the end of the Second World War and the early 1970s.
+Significant declines occurred in the 1960s, as more than 15,000 jaguars were yearly killed for their skins in the Brazilian Amazon alone; the trade in jaguar skins decreased since 1973 when the Convention on International Trade in Endangered Species was enacted.
+Interview surveys with 533 people in the northwestern Bolivian Amazon revealed that local people killed jaguars out of fear, in retaliation, and for trade.
+Between August 2016 and August 2019, jaguar skins and body parts were seen for sale in tourist markets in the Peruvian cities of Lima, Iquitos and Pucallpa.Human-wildlife conflict, opportunistic hunting and hunting for trade in domestic markets are key drivers for killing jaguars in Belize and Guatemala.
+Seizure reports indicate that at least 857 jaguars were involved in trade between 2012 and 2018, including 482 individuals in Bolivia alone; 31 jaguars were seized in China.
+Between 2014 and early 2019, 760 jaguar fangs were seized that originated in Bolivia and were destined for China. Undercover investigations revealed that the smuggling of jaguar body parts is run by Chinese residents in Bolivia.
+
+
+== Conservation ==
+The jaguar is listed on CITES Appendix I, which means that all international commercial trade in jaguars or their body parts is prohibited. Hunting jaguars is prohibited in Argentina, Brazil, Colombia, French Guiana, Honduras, Nicaragua, Panama, Paraguay, Suriname, the United States, and Venezuela. Hunting jaguars is restricted in Guatemala and Peru. In Ecuador, hunting jaguars is prohibited, and it is classified as threatened with extinction.
+In Guyana, it is protected as an endangered species, and hunting it is illegal.
+
+In 1986, the Cockscomb Basin Wildlife Sanctuary was established in Belize as the world's first protected area for jaguar conservation.
+
+
+=== Jaguar Conservation Units ===
+In 1999, field scientists from 18 jaguar range countries determined the most important areas for long-term jaguar conservation based on the status of jaguar population units, stability of prey base and quality of habitat. These areas, called "Jaguar Conservation Units" (JCUs), are large enough for at least 50 breeding individuals and range in size from 566 to 67,598 km2 (219 to 26,100 sq mi); 51 JCUs were designated in 36 geographic regions including:
+the Sierra Madre Occidental and Sierra de Tamaulipas in Mexico
+the Selva Maya tropical forests extending over Mexico, Belize and Guatemala
+the Chocó–Darién moist forests from Honduras and Panama to Colombia
+Venezuelan Llanos
+northern Cerrado and Amazon basin in Brazil
+Tropical Andes in Bolivia and Peru
+Misiones Province in ArgentinaOptimal routes of travel between core jaguar population units were identified across its range in 2010 to implement wildlife corridors that connect JCUs. These corridors represent areas with the shortest distance between jaguar breeding populations, require the least possible energy input of dispersing individuals and pose a low mortality risk. They cover an area of 2,600,000 km2 (1,000,000 sq mi) and range in length from 3 to 1,102 km (1.9 to 684.8 mi) in Mexico and Central America and from 489.14 to 1,607 km (303.94 to 998.54 mi) in South America.
+Cooperation with local landowners and municipal, state, or federal agencies is essential to maintain connected populations and prevent fragmentation in both JCUs and corridors.
+Seven of 13 corridors in Mexico are functioning with a width of at least 14.25 km (8.85 mi) and a length of no more than 320 km (200 mi). The other corridors may hamper passage, as they are narrower and longer.In August 2012, the United States Fish and Wildlife Service set aside 3,392.20 km2 (838,232 acres) in Arizona and New Mexico for the protection of the jaguar. The Jaguar Recovery Plan was published in April 2019, in which Interstate 10 is considered to form the northern boundary of the Jaguar Recovery Unit in Arizona and New Mexico.In Mexico, a national conservation strategy was developed from 2005 on and published in 2016. The Mexican jaguar population increased from an estimated 4,000 individuals in 2010 to about 4,800 individuals in 2018. This increase is seen as a positive effect of conservation measures that were implemented in cooperation with governmental and non-governmental institutions and landowners.An evaluation of JCUs from Mexico to Argentina revealed that they overlap with high-quality habitats of about 1,500 mammals to varying degrees. Since co-occurring mammals benefit from the JCU approach, the jaguar has been called an umbrella species.
+Central American JCUs overlap with the habitat of 187 of 304 regional endemic amphibian and reptile species, of which 19 amphibians occur only in the jaguar range.
+
+
+=== Approaches ===
+
+In setting up protected reserves, efforts generally also have to be focused on the surrounding areas, as jaguars are unlikely to confine themselves to the bounds of a reservation, especially if the population is increasing in size. Human attitudes in the areas surrounding reserves and laws and regulations to prevent poaching are essential to make conservation areas effective.To estimate population sizes within specific areas and to keep track of individual jaguars, camera trapping and wildlife tracking telemetry are widely used, and feces are sought out with the help of detection dogs to study jaguar health and diet.Current conservation efforts often focus on educating ranch owners and promoting ecotourism. Ecotourism setups are being used to generate public interest in charismatic animals such as the jaguar while at the same time generating revenue that can be used in conservation efforts. A key concern in jaguar ecotourism is the considerable habitat space the species requires. If ecotourism is used to aid in jaguar conservation, some considerations need to be made as to how existing ecosystems will be kept intact, or how new ecosystems will be put into place that are large enough to support a growing jaguar population.
+
+
+== In culture and mythology ==
+
+In the pre-Columbian Americas, the jaguar was a symbol of power and strength. In the Andes, a jaguar cult disseminated by the early Chavín culture became accepted over most of today's Peru by 900 BC. The later Moche culture in northern Peru used the jaguar as a symbol of power in many of their ceramics. In the Muisca religion in Altiplano Cundiboyacense, the jaguar was considered a sacred animal, and people dressed in jaguar skins during religious rituals.
+The skins were traded with peoples in the nearby Orinoquía Region.
+The name of the Muisca ruler Nemequene was derived from the Chibcha words nymy and quyne, meaning "force of the jaguar".Sculptures with "Olmec were-jaguar" motifs were found on the Yucatán Peninsula in Veracruz and Tabasco; they show stylized jaguars with half-human faces. In the later Maya civilization, the jaguar was believed to facilitate communication between the living and the dead and to protect the royal household. The Maya saw these powerful felines as their companions in the spiritual world, and several Maya rulers bore names that incorporated the Mayan word for jaguar b'alam in many of the Mayan languages. Balam remains a common Maya surname, and it is also the name of Chilam Balam, a legendary author to whom are attributed 17th and 18th-centuries Maya miscellanies preserving much important knowledge. Remains of jaguar bones were discovered in a burial site in Guatemala, which indicates that Mayans may have kept jaguars as pets.The Aztec civilization shared this image of the jaguar as the representative of the ruler and as a warrior. The Aztecs formed an elite warrior class known as the Jaguar warrior. In Aztec mythology, the jaguar was considered to be the totem animal of the powerful deity Tezcatlipoca.A conch shell gorget depicting a jaguar was found in a burial mound in Benton County, Missouri. The gorget shows evenly-engraved lines and measures 104 mm × 98 mm (4.1 in × 3.9 in).
+Rock drawings made by the Hopi, Anasazi and Pueblo all over the desert and chaparral regions of the American Southwest show an explicitly spotted cat, presumably a jaguar, as it is drawn much larger than an ocelot.The jaguar is also used as a symbol in contemporary culture. It is the national animal of Guyana and is featured in its coat of arms.
+The flag of the Department of Amazonas features a black jaguar silhouette leaping towards a hunter.
+The crest of the Argentine Rugby Union features a jaguar.

+The lechwe, red lechwe, or southern lechwe (Kobus leche) is an antelope found in wetlands of south-central Africa.
+
+
+== Range ==
+The lechwe is native to Botswana, Zambia, southeastern Democratic Republic of the Congo, northeastern Namibia, and eastern Angola, especially in the Okavango Delta, Kafue Flats, and Bangweulu Wetlands. The species is fairly common in zoos and wild animal farms.
+
+
+== Description ==
+Adult lechwe typically stand 90 to 100 cm (35 to 39 in) at the shoulder and generally weigh from 50 to 120 kg (110 to 260 lb), with males being larger than females. They are golden brown with white bellies. Males are darker in colour, but exact hue and amount of blackish on the front legs, chest and body varies depending on subspecies. The long, spiral horns are vaguely lyre-shaped and borne only by males. The hind legs are somewhat longer in proportion than in other antelopes to ease long-distance running on marshy soil.
+
+		
+		
+		
+
+
+== Habitats ==
+Lechwe are found in marshy areas where they are an important herbivore of aquatic plants. They use the knee-deep water as protection from predators. Their legs are covered in a water-repellant substance which allows them to run quite fast in knee-deep water. Lechwe are diurnal. They gather in herds which can include many thousands of individuals. Herds are usually all of one sex, but during mating season they mix.
+
+
+== Taxonomy ==
+
+
+=== Subspecies ===
+
+Four subspecies of the lechwe have been recognized.
+Common red lechwe (Kobus leche leche) (Gray, 1850) - Widely distributed in the wetlands of Zimbabwe, Botswana, Namibia and Zambia.
+Kafue Flats lechwe (Kobus leche kafuensis) (Haltenorth, 1963) - It is confined within the Kafue Flats (seasonally inundated flood-plain on the Kafue River, Zambia).
+† Roberts' lechwe (Kobus leche robertsi) (Rothschild, 1907) - Formerly found in northeastern Zambia, now extinct. Also called the Kawambwa lechwe.
+Black lechwe (Kobus leche smithemani) (Lydekker, 1900) - Found in the Bangweulu region of Zambia.In addition, the Upemba lechwe (Kobus anselli) and the extinct Cape lechwe (Kobus venterae) are also considered subspecies by some authorities (as Kobus leche anselli and Kobus leche venterae).Although related and sharing the name "lechwe", the Nile lechwe (K. megaceros) is consistently recognized as a separate species.

+The California kingsnake (Lampropeltis californiae) is a nonvenomous colubrid snake endemic to the western United States and northern Mexico, and is found in a variety of habitats. Due to ease of care and a wide range of color variations, the California kingsnake is one of the most popular snakes in captivity.
+
+
+== Description ==
+The California kingsnake is on average 2.5 to 3.5 feet long (76 – 107 cm) though they can grow larger; California kingsnakes on Islas Angel de la Guarda, Baja California, Mexico, have been documented growing to 78 inches (2 m). A wide range of color morphs exist in the wild; they are usually found with alternating dark and light bands ranging in color from black and white to brown and cream. Some populations may have longitudinal stripes instead of bands.
+
+
+== Range and habitat ==
+The California kingsnake is widespread along the West Coast of North America to elevations of approximately 6,100 ft (1,900 m) in the Tehachapi Mountains and to over 7,000 ft (2,100 m) in the southeastern Sierra Nevada Mountains. This species lives in a wide variety of habitats, including woodland chaparral, grassland, deserts, marshes, and even suburban areas. These snakes live in Oregon, California, Nevada, Utah, Arizona, southwestern Colorado, northwestern New Mexico, and northwestern Mexico. In Arizona, they intergrade with the desert kingsnake (Lampropeltis splendida) and the Mexican black kingsnake (Lampropeltis getula nigrita). The species has also become invasive on the Spanish island of Gran Canaria.
+
+
+== Behavior ==
+
+The California kingsnake is a cathemeral species of snake; they may be active day or night depending on ambient temperatures. During colder months they retreat underground and enter a hibernation-like state called brumation. When disturbed, California kingsnakes will often coil their bodies to hide their heads, hiss, and rattle their tails, which can produce a sound somewhat resembling that of a rattlesnake. When they are nervous they tend to twitch their tails. They are considered harmless to humans, but if handled it is common for this species to bite, as well as excrete musk and fecal contents from their cloaca.
+
+
+== Diet ==
+California kingsnakes are opportunistic feeders and common food items include rodents, birds, other reptiles and amphibians. The "king" in their name refers to their propensity to hunt and eat other snakes, including venomous rattlesnakes; California kingsnakes are naturally resistant to the venom of rattlesnakes. California kingsnakes are non-venomous and kill prey by constriction; they are the strongest constrictors proportionate to body size of any snakes. This adaptation may have evolved in response to the kingsnake's preferred reptilian prey, which needs less oxygen to survive an attack by constriction than mammalian prey items.
+
+
+== Reproduction ==
+The California kingsnake is an oviparous internal fertilization animal, meaning it lays eggs, as opposed to giving live birth like some other snakes.  Courtship for this kingsnake begins in the spring usually sometime after their hibernation or first shedding and involves the males competing for available females. In order to assert dominance when fighting another male, the California Kingsnake will get onto the other male and proceed biting the other snake. Their mating ritual begins by the male snake vibrating uncontrollably. Eggs are laid between May and August, which is generally 42–63 days after mating; in preparation the female will have chosen a suitable location. The typical clutch size is five to 12 eggs with an average of nine, though clutches of 20 or more eggs are known. The hatchlings usually emerge another 40–65 days later and are approximately eight to 13 inches in length. Adult California kingsnakes are most commonly 2.5–3.5 feet in length, and rarely exceed four feet.
+
+
+== In captivity ==
+The California kingsnake is one of the most popular pet reptiles due to its ease of care, attractive appearance and docile demeanor. Due to natural color and pattern variability between individual snakes, snake enthusiasts have selectively bred for a variety of color patterns known as "morphs". Wild-type California kingsnakes are technically illegal to sell without special permits in their home state of California. These increased restrictions are due to a law that prohibits sale of native California species within state lines; albino morphs are exempt from this law. The law is loosely enforced.

+Lampropeltis getula, commonly known as the eastern kingsnake, common kingsnake, or chain kingsnake,  is a harmless colubrid species endemic to the United States and Mexico. It has long been a favorite among collectors. Nine subspecies are currently recognized, including the nominate subspecies described here.
+
+
+== Description ==
+ 
+
+Adult specimens of the speckled kingsnake, L. g. holbrooki, are the smallest race at 91.5 cm (36.0 in) in snout-to-vent length (SVL) on average, while L. g. getula is the largest at 107 cm (42 in) SVL on average. Specimens up to 208.2 cm (82.0 in) in total length (including tail) have been recorded. Weight can vary from 285 g (10.1 oz) in a small specimen of 87.2 cm (34.3 in) in total length, to 2,268 g (80.0 oz) in large specimens, of over 153 cm (60 in) in total length.The color pattern consists of a glossy black, blue black, or dark brown ground color, overlaid with a series of 23-52 white chain-like rings. Kingsnakes from the coastal plains have wider bands, while those found in mountainous areas have thinner bands or may be completely black.
+
+
+== Common names ==
+Common names for L. getula include eastern kingsnake, common kingsnake, chain kingsnake, kingsnake, Carolina kingsnake, chain snake, bastard horn snake, black kingsnake, black moccasin, common chain snake, cow sucker, eastern kingsnake, horse racer, master snake, North American kingsnake, oakleaf rattler, pied snake, pine snake, racer, rattlesnake pilot, thunder-and-lightning snake, thunderbolt, thunder snake, wamper, wampum snake. In North Carolina, it is also called the pied piper.
+
+
+== Geographic range ==
+L. getula is found in the United States in Alabama, Arizona, Arkansas, California, portions of Colorado, Delaware, Florida, Georgia, south and southwest Illinois, southern Indiana, southern Iowa, Kansas, Kentucky, Louisiana, Maryland, Mississippi, Missouri, Nebraska, southern and western Nevada, New Jersey, New Mexico, New York, North Carolina, southern Ohio, Oklahoma, southern Oregon, South Carolina, Tennessee, Texas, southern Utah, Virginia, and West Virginia. It is also found in northern Mexico, including all of Baja California. It has been introduced to Gran Canaria in the Canary Islands, where in 2014,  the population had reached an estimated 20,000 individuals.
+
+
+== Habitat ==
+The preferred habitats of L. getula are open areas, particularly grassland, but also chaparral, oak woodland, abandoned farms, desert, low mountains, sand, and any type of riparian zone, including swamps, canals, and streams. A study on the habitat use of the Eastern Kingsnake found that overall they prefer and can be found in sites with thick layer of leaf litter and dense shrubbery. From their observations throughout the course of research, they found that 79% of their tracked specimen spent the majority of their time concealed under the cover of soil and leaf litter.Although commonly described as diurnal, some reports suggest that the Eastern Kingsnake are crepuscular or nocturnal during the hottest parts of the year It has been found that Eastern Kingsnake home ranges often show little-to-no overlap.Some studies show that Eastern Kingsnakes (L. g. getula), especially males, are territorial, and will commence in combat if their territory is threatened by another snake.
+
+
+== Diet ==
+L. getula eats other snakes, including venomous snakes such as copperheads (Agkistrodon contortrix), which are responsible for more venomous snakebites than any other in the United States, as well as coral snakes (Micruroides and Micrurus), massasaugas (Sistrurus catenatus), and other rattlesnakes (Crotalus and Sistrurus). Among the non-venomous snakes preyed upon include common garter snakes (Thamnophis sirtalis), common watersnakes (Nerodia sipedon), ring-necked snakes (Diadophis punctatus), smooth earth snakes (Virginia valeriae), and worm snakes (Carphophis amoenus).It has developed a hunting technique to avoid being bitten by clamping down on the jaws of the venomous prey, but even if envenomated, it is immune. It also eats amphibians, turtle eggs, bird eggs (including those of the northern bobwhite [Colinus virginianus]), lizards (such as five-lined skinks [Plestiodon fasciatus]), and small mammals (such as white-footed mice [Peromyscus leucopus]), which it kills by constriction.Due to their diet of eating other snake species, kingsnakes are a key factor in the spread of ophidiomycosis. This is a relatively new snake fungal disease originating from the fungus, Ophidiomyces ophiodiicola. This disease has a variety of impacts on snakes and the extent of this impact is still being researched.
+
+
+== Reproduction ==
+L. getula is oviparous. Adult females lay up to several dozen eggs that hatch after 2.0-2.5 months of incubation. Hatchlings are brightly colored and feed on small snakes, lizards, and rodents. Eastern Kingsnakes (L. g. getula) are active from April–October in most parts of their habitat range and breeding occurs in the spring months. Neck-biting is a common behavior when mating.
+
+
+== In captivity ==
+Long a favorite among collectors, L. getula does well in captivity, living to 25 years or more. Some of the most popular subspecies of the common kingsnake kept in captivity are the California, Brooks', Florida, and Mexican black kingsnakes.

+The ring-tailed lemur (Lemur catta) is a large strepsirrhine primate and the most recognized lemur due to its long, black and white ringed tail. It belongs to Lemuridae, one of five lemur families, and is the only member of the Lemur genus. Like all lemurs it is endemic to the island of Madagascar and endangered. Known locally in Malagasy as maky ([makʲ] (listen), spelled maki in French) or hira, it inhabits gallery forests to spiny scrub in the southern regions of the island. It is omnivorous and the most terrestrial of extant lemurs. The animal is diurnal, being active exclusively in daylight hours.
+The ring-tailed lemur is highly social, living in groups of up to 30 individuals.  It is also female dominant, a trait common among lemurs. To keep warm and reaffirm social bonds, groups will huddle together. The ring-tailed lemur will also sunbathe, sitting upright facing its underside, with its thinner white fur towards the sun. Like other lemurs, this species relies strongly on its sense of smell and marks its territory with scent glands.  The males perform a unique scent marking behavior called spur marking and will participate in stink fights by marking their tail with their scent and wafting it at opponents.
+As one of the most vocal primates, the ring-tailed lemur uses numerous vocalizations including group cohesion and alarm calls.  Experiments have shown that the ring-tailed lemur, despite the lack of a large brain (relative to simiiform primates), can organize sequences, understand basic arithmetic operations and preferentially select tools based on functional qualities.
+Despite reproducing readily in captivity and being the most populous lemur in zoos worldwide, numbering more than 2,000 individuals, the ring-tailed lemur is listed as endangered by the IUCN Red List due to habitat destruction and hunting for bushmeat and the exotic pet trade. As of early 2017, the population in the wild is believed to have crashed as low as 2,000 individuals due to habitat loss, poaching and hunting, making them far more critically endangered.
+
+
+== Etymology ==
+Although the term "lemur" was first intended for slender lorises, it was soon limited to the endemic Malagasy primates, which have been known as "lemurs" ever since. The name derives from the Latin term lemures, which refers to specters or ghosts that were exorcised during the Lemuria festival of ancient Rome. According to Carl Linnaeus's own explanation, the name was selected because of the nocturnal activity and slow movements of the slender loris. Being familiar with the works of Virgil and Ovid and seeing an analogy that fit with his naming scheme, Linnaeus adapted the term "lemur" for these nocturnal primates. However, it has been commonly and falsely assumed that Linnaeus was referring to the ghost-like appearance, reflective eyes, and ghostly cries of lemurs. It has also been speculated that Linnaeus may also have known that some Malagasy people have held legends that lemurs are the souls of their ancestors, but this is unlikely given that the name was selected for slender lorises from India. The species name, catta, refers to the ring-tailed lemur's cat-like appearance.  Its purring vocalization is similar to that of the domestic cat.Following Linnaeus's species description, the common name "ring-tailed maucauco" was first penned in 1771 by Welsh naturalist Thomas Pennant, who made note of its characteristic long, banded tail. (The term "maucauco" was a very common term for lemurs at this time.) The now universal English name "ring-tailed lemur" was first used by George Shaw in his illustrated scientific publication covering the Leverian collection, which was published between 1792 and 1796.
+
+
+== Evolutionary history ==
+All mammalian fossils from Madagascar come from recent times. Thus, little is known about the evolution of the ring-tailed lemur, let alone the rest of the lemur clade, which comprises the entire endemic primate population of the island.  However, chromosomal and molecular evidence suggest that lemurs are more closely related to each other than to other strepsirrhine primates.  For this to have happened, it is thought that a very small ancestral population came to Madagascar via a single rafting event between 50 and 80 million years ago. Subsequent evolutionary radiation and speciation has created the diversity of Malagasy lemurs seen today.
+
+According to analysis of amino acid sequences, the branching of the family Lemuridae has been dated to 26.1 ±3.3 mya while rRNA sequences of mtDNA place the split at 24.9 ±3.6 mya.  The ruffed lemurs are the first genus to split away (most basal) in the family, a view that is further supported by analysis of DNA sequences and karyotypes.  Additionally, Molecular data suggests a deep genetic divergence and sister group relationship between the true lemurs (Eulemur) and the other two genera: Lemur and Hapalemur.The ring-tailed lemur is thought to share closer affinities to the bamboo lemurs of the genus Hapalemur than to the other two genera in its family. This has been supported by comparisons in communication, chromosomes, genetics, and several morphological traits, such as scent gland similarities.  However, other data concerning immunology and other morphological traits fail to support this close relationship. For example, Hapalemur species have short snouts, while the ring-tailed lemur and the rest of Lemuridae have long snouts. However, differences in the relationship between the orbit (eye socket) and the muzzle suggest that the ring-tailed lemur and the true lemurs evolved their elongated faces independently.The relationship between the ring-tailed lemur and bamboo lemurs is the least understood. Molecular analysis suggests that either the bamboo lemurs diverged from the ring-tailed lemur, making the group monophyletic and supporting the current two-genera taxonomy, or that the ring-tailed lemur is nested in with the bamboo lemurs, requiring Hapalemur simus to be split off into its own genus, Prolemur.The karyotype of the ring-tailed lemur has 56 chromosomes, of which four are metacentric (arms of nearly equal length), four are submetacentric (arms of unequal length), and 46 are acrocentric (the short arm is hardly observable).  The X chromosome is metacentric and the Y chromosome is acrocentric.
+
+
+=== Taxonomic classification ===
+Linnaeus first used the genus name Lemur to describe "Lemur tardigradus" (the red slender loris, now known as Loris tardigradus) in his 1754 catalog of the Museum of King Adolf Frederick.  In 1758, his 10th edition of Systema Naturae listed the genus Lemur with three included species, only one of which is still considered to be a lemur while another is no longer considered to be a primate. These species include: Lemur tardigradus, Lemur catta (the ring-tailed lemur), and Lemur volans (the Philippine colugo, now known as Cynocephalus volans).  In 1911, Oldfield Thomas made Lemur catta the type species for the genus, despite the term initially being used to describe lorises.  On January 10, 1929, the International Commission on Zoological Nomenclature (ICZN) formalized this decision in its publication of Opinion 122.The ring-tailed lemur shares many similarities with ruffed lemurs (genus Varecia) and true lemurs (genus Eulemur), and its skeleton is nearly indistinguishable from that of the true lemurs. Consequently, the three genera were once grouped together in the genus Lemur and more recently are sometimes referred to as subfamily Lemurinae (within family Lemuridae).  However, ruffed lemurs were reassigned to the genus Varecia in 1962, and due to similarities between the ring-tailed lemur and the bamboo lemurs, particularly in regards to molecular evidence and scent glands similarities, the true lemurs were moved to the genus Eulemur by Yves Rumpler and Elwyn L. Simons (1988) as well as Colin Groves and Robert H. Eaglen (1988).  In 1991, Ian Tattersall and Jeffrey H. Schwartz reviewed the evidence and came to a different conclusion, instead favoring to return the members of Eulemur and Varecia to the genus Lemur.  However, this view was not widely accepted and the genus Lemur remained monotypic, containing only the ring-tailed lemur.  Because the differences in molecular data are so minute between the ring-tailed lemur and both genera of bamboo lemurs, it has been suggested that all three genera be merged.Because of the difficulty in discerning the relationships within family Lemuridae, not all authorities agree on the taxonomy, although the majority of the primatological community favors the current classification.
+In 1996, researchers Steven Goodman and Olivier Langrand suggested that the ring-tailed lemur may demonstrate regional variations, particularly a high mountain population at Andringitra Massif that has a thicker coat, lighter coloration, and variations in its tail rings. In 2001, primatologist Colin Groves concluded that this does not represent a locally occurring subspecies.  This decision was later supported by further fieldwork that showed that the differences fell within the normal range of variation for the species.  The thicker coat was considered a local adaptation to extreme low temperatures in the region, and the fading of the fur was attributed to increased exposure to solar radiation.  Additional genetic studies in 2000 further supported the conclusion that population did not vary significantly from the other ring-tailed lemur populations on the island.
+
+
+== Anatomy and physiology ==
+
+The ring-tailed lemur is a relatively large lemur.  Its average weight is 2.2 kilograms (4.9 lb). Its head–body length ranges between 39 and 46 cm (15 and 18 in), its tail length is 56 and 63 cm (22 and 25 in), and its total length is 95 and 110 cm (37 and 43 in).  Other measurements include a hind foot length of 102 and 113 mm (4.0 and 4.4 in), ear length of 40 and 48 mm (1.6 and 1.9 in), and cranium length of 78 and 88 mm (3.1 and 3.5 in).The species has a slender frame and narrow face, fox-like muzzle.  The ring-tailed lemur's trademark—a long, bushy tail—is ringed in alternating black and white transverse bands, numbering 12 or 13 white rings and 13 or 14 black rings, and always ending in a black tip.  The total number of rings nearly matches the approximate number of caudal vertebrae (~25). Its tail is longer than its body and is not prehensile.  Instead, it is only used for balance, communication, and group cohesion.The pelage (fur) is so dense that it can clog electric clippers. The ventral (chest) coat and throat are white or cream. The dorsal (back) coat varies from gray to rosy-brown, sometimes with a brown pygal patch around the tail region, where the fur grades to pale gray or grayish brown. The dorsal coloration is slightly darker around the neck and crown. The hair on the throat, cheeks, and ears is white or off-white and also less dense, allowing the dark skin underneath to show through. The muzzle is dark grayish and the nose is black, and the eyes are encompassed by black triangular patches.  Facial vibrissae (whiskers) are developed and found above the lips (mystacal), on the cheeks (genal), and on the eyebrow (superciliary).  Vibrissae are also found slightly above the wrist on the underside of the forearm.  The ears are relatively large compared to other lemurs and are covered in hair, which has only small tufts if any.  Although slight pattern variations in the facial region may be seen between individuals, there are no obvious differences between the sexes.Unlike most diurnal primates, but like all strepsirrhine primates, the ring-tailed lemur has a tapetum lucidum, or reflective layer behind the retina of the eye, that enhances night vision.  The tapetum is highly visible in this species because the pigmentation of the ocular fundus (back surface of the eye), which is present in—but varies between—all lemurs, is very spotty.  The ring-tailed lemur also has a rudimentary foveal depression on the retina.  Another shared characteristic with the other strepsirrhine primates is the rhinarium, a moist, naked, glandular nose supported by the upper jaw and protruding beyond the chin.  The rhinarium continues down where it divides the upper lip.  The upper lip is attached to the premaxilla, preventing the lip from protruding and thus requiring the lemur to lap water rather than using suction.
+
+The skin of the ring-tailed lemur is dark gray or black in color, even in places where the fur is white.  It is exposed on the nose, palms, soles, eyelids, lips, and genitalia.  The skin is smooth, but the leathery texture of the hands and feet facilitate terrestrial movement.  The anus, located at the joint of the tail, is covered when the tail is lowered.  The area around the anus (circumanal area) and the perineum are covered in fur.  In males, the scrotum lacks fur, is covered in small, horny spines, and the two sacs of the scrotum are divided.  The penis is nearly cylindrical in shape and is covered in small spines, as well as having two pairs of larger spines on both sides.  Males have a relatively small baculum (penis bone) compared to their size.  The scrotum, penis, and prepuce are usually coated with a foul-smelling secretion.  Females have a thick, elongated clitoris that protrudes from the labia of the vulva.  The opening of the urethra is closer to the clitoris than the vagina, forming a "drip tip".Females have two pairs of mammary glands (four nipples), but only one pair is functional.  The anterior pair (closest to the head) are very close to the axillae (armpit).  Furless scent glands are present on both males and females.  Both sexes have small, dark antebrachial (forearm) glands measuring 1 cm long and located on the inner surface of the forearm nearly 25 cm (9.8 in) above the wrist joint.  (This trait is shared between the Lemur and Hapalemur genera.) The gland is soft and compressible, bears fine dermal ridges (like fingerprints), and is connected to the palm by a fine, 2 mm–high, hairless strip.  However, only the male has a horny spur that overlays this scent gland.  The spur develops with age through the accumulation of secretions from an underlying gland that may connect through the skin through as many as a thousand minuscule  ducts. The males also have brachial (arm) glands on the axillary surface of their shoulders (near the armpit). The brachial gland is larger than the antebrachial gland, covered in short hair around the periphery, and has a naked crescent-shaped orifice near the center.  The gland secretes a foul-smelling, brown, sticky substance. The brachial gland is barely developed if present at all in females.  Both genders also have apocrine and sebaceous glands in their genital or perianal regions, which are covered in fur.Its fingers are slender, padded, mostly lacking webbing, and semi-dexterous with flat, human-like nails.  The thumb is both short and widely separated from the other fingers.  Despite being set at a right angle to the palm, the thumb is not opposable since the ball of the joint is fixed in place.  As with all strepsirrhines, the hand is ectaxonic (the axis passes through the fourth digit) rather than mesaxonic (the axis passing through the third digit) as seen in monkeys and apes.  The fourth digit is the longest, and only slightly longer than the second digit.  Likewise, the fifth digit is only slightly longer than the second.  The palms are long and leathery, and like other primates, they have dermal ridges to improve grip.  The feet are semi-digitigrade and more specialized than the hands.  The big toe is opposable and is smaller than the big toe of other lemurs, which are more arboreal.  The second toe is short, has a small terminal pad, and has a toilet-claw (sometimes referred to as a grooming claw) specialized for personal grooming, specifically to rake through fur that is unreachable by the mouth.  The toilet-claw is a trait shared among nearly all living strepsirrhine primates.  Unlike other lemurs, the ring-tailed lemur's heel is not covered by fur.

+The ring-tailed lemur has a dentition of 2.1.3.32.1.3.3 × 2 = 36, meaning that on each side of the jaw it has two incisors, one canine tooth, three premolars, and three molar teeth.  Its deciduous dentition is 2.1.32.1.3 × 2 = 24.  The permanent teeth erupt in the following order: m 1/1 (first molars), i 2/2 (first incisors), i 3/3 (second incisors), C1 (upper canines), m 2/2 (second molars), c1 (lower canines), m 3/3 (third molars), p 4/4 (third premolars), p 3/3 (second premolars), p 2/2 (first premolars).Its lower incisors (i1 and i2) are long, narrow, and finely spaced while pointing almost straight forward in the mouth (procumbent).  Together with the incisor-shaped (incisiform) lower canines (c1), which are slightly larger and also procumbent, form a structure called a toothcomb, a trait unique to nearly all strepsirrhine primates.  The toothcomb is used during oral grooming, which involves licking and tooth-scraping.  It may also be used for grasping small fruits, removing leaves from the stem when eating, and possibly scraping sap and gum from tree bark.  The toothcomb is kept clean using a sublingual organ—a thin, flat, fibrous plate that covers a large part of the base of the tongue.  The first lower premolar (p2) following the toothcomb is shaped like a canine (caniniform) and occludes the upper canine, essentially filling the role of the incisiform lower canine.  There is also a diastema (gap) between the second and third premolars (p2 and p3).The upper incisors are small, with the first incisors (I1) space widely from each other, yet closely to the second incisors (I2).  Both are compressed buccolingually (between the cheek and the tongue).  The upper canines (C1) are long, have a broad base, and curve down and back (recurved).  The upper canines exhibit slight sexual dimorphism, with males exhibiting slightly larger canines than females.  Both sexes use them in combat by slashing with them.  There is a small diastema between the upper canine and the first premolar (P2), which is smaller and more caniniform than the other premolars.  Unlike other lemurs, the first two upper molars (M1 and M2) have prominent lingual cingulae, yet do not have a protostyle.
+
+
+== Ecology ==
+The ring-tailed lemur is diurnal and semi-terrestrial. It is the most terrestrial of lemur species, spending as much as 33% of its time on the ground. However it is still considerably arboreal, spending 23% of its time in the mid-level canopy, 25% in the upper-level canopy, 6% in the emergent layer and 13% in small bushes. Troop travel is 70% terrestrial.Troop size, home range, and population density vary by region and food availability. Troops typically range in size from 6 to 25, although troops with over 30 individuals have been recorded. The average troop contains 13 to 15 individuals. Home range size varies between 6 and 35 hectares (15 and 86 acres). Troops of the ring-tailed lemur will maintain a territory, but overlap is often high. When encounters occur, they are agonistic, or hostile in nature. A troop will usually occupy the same part of its range for three or four days before moving. When it does move, the average traveling distance is 1 km (0.62 mi). Population density ranges from 100 individuals per 1 km2 (0.39 sq mi) in dry forests to 250–600 individuals per km2 in gallery and secondary forests.The ring-tailed lemur has both native and introduced predators. Native predators include the fossa (Cryptoprocta ferox), the Madagascar harrier-hawk (Polyboroides radiatus), the Madagascar buzzard (Buteo brachypterus) and the Madagascar ground boa (Acrantophis madagascariensis). Introduced predators include the small Indian civet (Viverricula indica), the domestic cat and the domestic dog.
+
+
+=== Geographic range and habitat ===
+Endemic to southern and southwestern Madagascar, the ring-tailed lemur ranges further into highland areas than other lemurs.  It inhabits deciduous forests, dry scrub, montane humid forests, and gallery forests (forests along riverbanks). It strongly favors gallery forests, but such forests have now been cleared from much of Madagascar in order to create pasture for livestock. Depending on location, temperatures within its geographic range can vary from −12 °C (10 °F) at Andringitra Massif to 48 °C (118 °F) in the spiny forests of Beza Mahafaly Special Reserve.This species is found as far east as Tôlanaro, inland towards the mountains of Andringitra on the southeastern plateau, among the spiny forests of the southern part of the island, and north along the west coast to the town of Belo sur Mer.  Historically, the northern limits of its range in the west extended to the Morondava River near Morondava.  It can still be found in Kirindy Mitea National Park, just south of Morondava, though at very low densities.  It does not occur in Kirindy Forest Reserve, north of Morondava.  Its distribution throughout the rest of its range is very spotty, with population densities varying widely.The ring-tailed lemur can be easily seen in five national parks in Madagascar: Andohahela National Park, Andringitra National Park, Isalo National Park, Tsimanampetsotse National Park, and Zombitse-Vohibasia National Park.  It can also be found in Beza-Mahafaly Special Reserve, Kalambatritra Special Reserve, Pic d'Ivohibe Special Reserve, Amboasary Sud, Berenty Private Reserve, Anja Community Reserve, and marginally at Kirindy Mitea National Park.  Unprotected forests that the species has been reported in include Ankoba, Ankodida, Anjatsikolo, Anbatotsilongolongo, Mahazoarivo, Masiabiby, and Mikea.Within the protected regions it is known to inhabit, the ring-tailed lemur is sympatric (shares its range) with as many as 24 species of lemur, covering every living genus except Allocebus, Indri, and Varecia.  Historically, the species used to be sympatric with the critically endangered southern black-and-white ruffed lemur (Varecia variegata editorum), which was once found at Andringitra National Park; however, no sightings of the ruffed lemur have been reported in recent years.
+In western Madagascar, sympatric ring-tailed lemurs and red-fronted lemurs (Eulemur rufifrons) have been studied together. Little interaction takes place between the two species. While the diets of the two species overlap, they eat in different proportions since the ring-tailed lemur has a more varied diet and spends more time on the ground.
+
+
+=== Diet ===
+The ring-tailed lemur is an opportunistic omnivore primarily eating fruits and leaves, particularly those of the tamarind tree (Tamarindus indica), known natively as kily. When available, tamarind makes up as much as 50% of the diet, especially during the dry, winter season. The ring-tailed lemur eats from as many as three dozen different plant species, and its diet includes flowers, herbs, bark and sap. It has been observed eating decayed wood, earth, spider webs, insect cocoons, arthropods (spiders, caterpillars, cicadas and grasshoppers) and small vertebrates (birds and chameleons). During the dry season it becomes increasingly opportunistic.
+
+
+== Behavior ==
+
+
+=== Social systems ===
+Troops are classified as multi-male groups, with a matriline as the core group. As with most lemurs, females socially dominate males in all circumstances, including feeding priority. Dominance is enforced by lunging, chasing, cuffing, grabbing and biting. Young females do not always inherit their mother's rank and young males leave the troop between three and five years of age. Both sexes have separate dominance hierarchies; females have a distinct hierarchy while male rank is correlated with age. Each troop has one to three central, high-ranking adult males who interact with females more than other group males and lead the troop procession with high-ranking females. Recently transferred males, old males or young adult males that have not yet left their natal group are often lower ranking. Staying at the periphery of the group they tend to be marginalized from group activity.
+
+For males, social structure changes can be seasonal. During the six-month period between December and May a few males immigrate between groups. Established males transfer on average every 3.5 years, although young males may transfer approximately every 1.4 years. Group fission occurs when groups get too large and resources become scarce.In the mornings the ring-tailed lemur sunbathes to warm itself. It faces the sun sitting in what is frequently described as a "sun-worshipping" posture or lotus position. However, it sits with its legs extended outward, not cross-legged, and will often support itself on nearby branches. Sunning is often a group activity, particularly during the cold mornings. At night, troops will split into sleeping parties huddling closely together to keep warm.Despite being quadrupedal the ring-tailed lemur can rear up and balance on its hind legs, usually for aggressive displays. When threatened the ring-tailed lemur may jump in the air and strike out with its short nails and sharp upper canine teeth in a behaviour termed jump fighting. This is extremely rare outside of the breeding season when tensions are high and competition for mates is intense. Other aggressive behaviours include a threat-stare, used to intimidate or start a fight, and a submissive gesture known as pulled-back lips.Border disputes with rival troops occur occasionally and it is the dominant female's responsibility to defend the troop's home range. Agonistic encounters include staring, lunging approaches and occasional physical aggression, and conclude with troop members retreating toward the center of the home range.
+
+
+==== Olfactory communication ====
+
+Olfactory communication is critically important for strepsirrhines like the ring-tailed lemur. Males and females scent mark both vertical and horizontal surfaces at the overlaps in their home ranges using their anogenital scent glands. The ring-tailed lemur will perform a handstand to mark vertical surfaces, grasping the highest point with its feet while it applies its scent. Use of scent marking varies by age, sex and social status. Male lemurs use their antebrachial and brachial glands to demarcate territories and maintain intragroup dominance hierarchies. The thorny spur that overlays the antebrachial gland on each wrist is scraped against tree trunks to create grooves anointed with their scent. This is known as spur-marking.In displays of aggression, males engage in a social display behaviour called stink fighting, which involves impregnating their tails with secretions from the antebrachial and brachial glands and waving the scented tail at male rivals.Ring-tailed lemurs have also been shown to mark using urine.  Behaviorally, there is a difference between regular urination, where the tail is slightly raised and a stream of urine is produced, and the urine marking behavior, where the tail is held up in display and only a few drops of urine are used.  The urine-marking behavior is typically used by females to mark territory, and has been observed primarily at the edges of the troop's territory and in areas where other troops may frequent.  The urine marking behavior also is most frequent during the mating season, and may play a role in reproductive communication between groups.
+
+
+==== Auditory communication ====
+
+The ring-tailed lemur is one of the most vocal primates and has a complex array of distinct vocalizations used to maintain group cohesion during foraging and alert group members to the presence of a predator.  Calls range from simple to complex.  An example of a simple call is the purr (listen ), which expresses contentment.  A complex call is the sequence of clicks, close-mouth click series (CMCS), open-mouth click series (OMCS) and yaps (listen ) used during predator mobbing. Some calls have variants and undergo transitions between variants, such as an infant "whit" (distress call) transitioning from one variant to another (listen ).The most commonly heard vocalizations are the moan (listen ) (low-to-moderate arousal, group cohesion), early-high wail (listen ) (moderate-to-high arousal, group cohesion), and clicks (listen ) ("location marker" to draw attention).
+
+
+=== Breeding and reproduction ===
+
+The ring-tailed lemur is polygynandrous, although the dominant male in the troop typically breeds with more females than other males. Fighting is most common during the breeding season. A receptive female may initiate mating by presenting her backside, lifting her tail and looking at the desired male over her shoulder. Males may inspect the female's genitals to determine receptiveness. Females typically mate within their troop, but may seek outside males.The breeding season runs from mid-April to mid-May. Estrus lasts 4 to 6 hours, and females mate with multiple males during this period.  Within a troop, females stagger their receptivity so that each female comes into season on a different day during the breeding season, reducing competition for male attention. Females lactate during the wet season, from December through April, when resources are readily available. Females gestate during the dry season, from May through September, when resources are low. Females give birth during seasons where resources, such as flowers, are in peak. Gestation lasts for about 135 days, and parturition occurs in September or occasionally October.  In the wild, one offspring is the norm, although twins may occur. Ring-tailed lemur infants have a birth weight of 70 g (2.5 oz) and are carried ventrally (on the chest) for the first 1 to 2 weeks, then dorsally (on the back).The young lemurs begin to eat solid food after two months and are fully weaned after five months. Sexual maturity is reached between 2.5 and 3 years. Male involvement in infant rearing is limited, although the entire troop, regardless of age or sex, can be seen caring for the young. Alloparenting between troop females has been reported. Kidnapping by females and infanticide by males also occur occasionally. Due to harsh environmental conditions, predation and accidents such as falls, infant mortality can be as high as 50% within the first year and as few as 30% may reach adulthood.  The longest-lived ring-tailed lemur in the wild was a female at the Berenty Reserve who lived for 20 years. In the wild, females rarely live past the age of 16, whereas the life expectancy of males is not known due to their social structure.  The longest-lived male was reported to be 15 years old.  The maximum lifespan reported in captivity was 27 years.
+
+
+=== Cognitive abilities and tool use ===
+Historically, the studies of learning and cognition in non-human primates have focused on simians (monkeys and apes), while strepsirrhine primates, such as the ring-tailed lemur and its allies, have been overlooked and popularly dismissed as unintelligent. A couple of factors stemming from early experiments have played a role in the development of this assumption. First, the experimental design of older tests may have favored the natural behavior and ecology of simians over that of strepsirrhines, making the experimental tasks inappropriate for lemurs. For example, simians are known for their manipulative play with non-food objects, whereas lemurs are only known to manipulate non-food objects in captivity. This behaviour is usually connected with food association. Also, lemurs are known to displace objects with their nose or mouth more so than with their hands.  Therefore, an experiment requiring a lemur to manipulate an object without prior training would favor simians over strepsirrhines. Second, individual ring-tailed lemurs accustomed to living in a troop may not respond well to isolation for laboratory testing. Past studies have reported hysterical behaviour in such scenarios.The notion that lemurs are unintelligent has been perpetuated by the view that the neocortex ratio (as a measure of brain size) indicates intelligence. In fact, primatologist Alison Jolly noted early in her academic career that some lemur species, such as the ring-tailed lemur, have evolved a social complexity similar to that of cercopithecine monkeys, but not the corresponding intelligence. After years of observations of wild ring-tailed lemur populations at the Berenty Reserve in Madagascar and as well as baboons in Africa, she more recently concluded that this highly social lemur species does not demonstrate the equivalent social complexity of cercopithecine monkeys, despite general appearances.Regardless, research has continued to illuminate the complexity of the lemur mind, with emphasis on the cognitive abilities of the ring-tailed lemur. As early as the mid-1970s, studies had demonstrated that they could be trained through operant conditioning using standard schedules of reinforcement. The species has been shown to be capable of learning pattern, brightness, and object discrimination, skills common among vertebrates. The ring-tailed lemur has also been shown to learn a variety of complex tasks often equaling, if not exceeding, the performance of simians.More recently, research at the Duke Lemur Center has shown that the ring-tailed lemur can organize sequences in memory and retrieve ordered sequences without language. The experimental design demonstrated that the lemurs were using internal representation of the sequence to guide their responses and not simply following a trained sequence, where one item in the sequence cues the selection of the next. But this is not the limit of the ring-tailed lemur's reasoning skills. Another study, performed at the Myakka City Lemur Reserve, suggests that this species along with several other closely related lemur species understand simple arithmetic operations.Since tool use is considered to be a key feature of primate intelligence, the apparent lack of this behavior in wild lemurs, as well as the lack of non-food object play, has helped reinforce the perception that lemurs are less intelligent than their simian cousins. However, another study at the Myakka City Lemur Reserve examined the representation of tool functionality in both the ring-tailed lemur and the common brown lemur and discovered that, like monkeys, they used tools with functional properties (e.g., tool orientation or ease of use) instead of tools with nonfunctional features (e.g., color or texture). Although the ring-tailed lemur may not use tools in the wild, it can not only be trained to use a tool, but will preferentially select tools based on their functional qualities. Therefore, the conceptual competence to use a tool may have been present in the common primate ancestor, even though the use of tools may not have appeared until much later.
+
+
+== Conservation status ==
+In addition to being listed as endangered in 2014 by the IUCN, the ring-tailed lemur has been listed since 1977 by CITES under Appendix I, which makes trade of wild-caught specimens illegal. Although there are more endangered species of lemur, the ring-tailed lemur is considered a flagship species due to its recognizability. As of 2017, only about 2,000 ring-tailed lemurs are estimated to be left in the wild, making the threat of extinction far more serious for them than previously believed.
+
+Three factors threaten ring-tailed lemurs. First and foremost is habitat destruction.  Starting nearly 2,000 years ago with the introduction of humans to the island, forests have been cleared to produce pasture and agricultural land. Extraction of hardwoods for fuel and lumber, as well mining and overgrazing, have also taken their toll.  Today, it is estimated that 90% of Madagascar's original forest cover has been lost. Rising populations have created even greater demand in the southwest portion of the island for fuel wood, charcoal, and lumber. Fires from the clearing of grasslands, as well as slash-and-burn agriculture destroy forests.  Another threat to the species is harvesting either for food (bushmeat), fur clothing or pets. Finally, periodic drought common to southern Madagascar can impact populations already in decline.  In 1991 and 1992, for example, a severe drought caused an abnormally high mortality rate among infants and females at the Beza Mahafaly Special Reserve.  Two years later, the population had declined by 31% and took nearly four years to start to recover.The ring-tailed lemur resides in several protected areas within its range, each offering varying levels of protection. At the Beza Mahafaly Special Reserve, a holistic approach to in-situ conservation has been taken.  Not only does field research and resource management involve international students and local people (including school children), livestock management is used at the peripheral zones of the reserve and ecotourism benefits the local people.Outside of its diminishing habitat and other threats, the ring-tailed lemur reproduces readily and has fared well in captivity.  For this reason, along with its popularity, it has become the most populous lemur in zoos worldwide, with more than 2500 in captivity as of 2009.  It is also the most common of all captive primates.  Ex situ facilities actively involved in the conservation of the ring-tailed lemur include the Duke Lemur Center in Durham, North Carolina, the Lemur Conservation Foundation in Myakka City, Florida, and the Madagascar Fauna Group headquartered at the Saint Louis Zoo.  Due to the high success of captive breeding, reintroduction is a possibility if wild populations were to crash.  Although experimental releases have met success on St. Catherines Island in Georgia, demonstrating that captive lemurs can readily adapt to their environment and exhibit a full range of natural behaviors, captive release is not currently being considered.Ring-tailed lemur populations can also benefit from drought intervention, due to the availability of watering troughs and introduced fruit trees, as seen at the Berenty Private Reserve in southern Madagascar.  However, these interventions are not always seen favorably, since natural population fluctuations are not permitted.  The species is thought to have evolved its high fecundity due to its harsh environment.

+== Cultural references ==
+The ring-tailed lemur is known locally in Malagasy as maky (pronounced [ˈmakʲi̥], and spelled maki in French) or hira (pronounced [ˈhirə] or colloquially [ˈir]).  Being the most widely recognized endemic primate on the island, it has been selected as the symbol for Madagascar National Parks (formerly known as ANGAP).  The Maki brand, which started by selling T-shirts in Madagascar and now sells clothing across the Indian Ocean islands, is named after this lemur due to its popularity, despite the fact that the company's logo portrays the face of a sifaka and its name uses the French spelling.The first mention of the ring-tailed lemur in Western literature came in 1625 when English traveler and writer Samuel Purchas described them as being comparable in size to a monkey and having a fox-like long tail with black and white rings. Charles Catton included the species in his 1788 book Animals Drawn from Nature and Engraved in Aqua-tinta, calling it the "Maucauco" and regarding it as a type of monkey.It has been popularized in Western culture by the Animal Planet television series Lemur Street, as well as by the character King Julien in the animated Madagascar film and TV franchise. The ring-tailed lemur was also the focus of the 1996 Nature documentary A Lemur's Tale, which was filmed at the Berenty Reserve and followed a troop of lemurs.  The troop included a special infant named Sapphire, who was nearly albino, with white fur, bright blue eyes, and the characteristic ringed tail.This species also played a role in the 1997 comedy film Fierce Creatures, starring John Cleese, who has a passion for lemurs. Cleese later hosted the 1998 BBC documentary In the Wild: Operation Lemur with John Cleese, which tracked the progress of a reintroduction of black-and-white ruffed lemurs back into the Betampona Reserve in Madagascar.  The project had been partly funded by Cleese's donation of the proceeds from the London premier of Fierce Creatures.

+The golden lion tamarin (Leontopithecus rosalia, Portuguese: mico-leão-dourado [ˈmiku leˈɐ̃w̃ dowˈɾadu], [liˈɐ̃w̃ doˈɾadu]), also known as the golden marmoset, is a small New World monkey of the family Callitrichidae. Native to the Atlantic coastal forests of Brazil, the golden lion tamarin is an endangered species. The range for wild individuals is spread across four places along southeastern Brazil, with a recent census estimating 3,200 individuals left in the wild and a captive population maintaining about 490 individuals among 150 zoos.
+
+
+== Physical characteristics ==
+
+The golden lion tamarin gets its name from its bright reddish orange pelage and the extra long hairs around the face and ears which give it a distinctive mane. Its face is dark and hairless. The bright orange fur of this species does not contain carotenoids, which commonly produce bright orange colors in nature. The golden lion tamarin is the largest of the callitrichines. It is typically around 261 mm (10.3 in) and weighs around 620 g (1.37 lb). There is almost no size difference between males and females. As with all New World monkeys, the golden lion tamarin has tegulae, which are claw-like nails, instead of ungulae or flat nails found in all other primates, including humans. Tegulae enable tamarins to cling to the sides of tree trunks. It may also move quadrupedally along the small branches, whether through walking, running, leaping or bounding. This gives it a locomotion more similar to squirrels than primates.
+
+
+== Habitat and distribution ==
+The Golden Lion Tamarin has a very limited distribution range, as over time they have lost all but 2%–5% of their original habitat in Brazil. Today, this tamarin is confined to three small areas of the tropical rain forest in southeastern Brazil: Poço das Antas Biological Reserve, Fazenda União Biological Reserve, and private land through the Reintroduction Program. The first population estimate made in 1972 approximated the count at between 400 and 500. By 1981 the population was reduced to less than 200. Surveys from as recently as 1995 suggested that there may only have been at most 400 golden lion tamarins left in the wild; but the population has since recovered to some 3200 in the wild. Tamarins live along the far southeast border of the country in the municipalities of Silva Jardim, Cabo Frio, Saquarema, and Araruama. However, they have been successfully reintroduced to the municipalities of Rio das Ostras, Rio Bonito, and Casimiro de Abreu. Tamarins live in coastal lowland forests less than 300 m (984 ft) above sea level. They can be found in hilltop forests and swamp forests.
+
+
+== Behaviour and ecology ==
+The golden lion tamarin is active for a maximum of 12 hours daily. It uses different sleeping dens each day. By frequently moving their sleeping nests around, groups minimize the scent left behind, reducing the likelihood of predators finding them. The first activities of the day are traveling and feeding on fruits. As the afternoon nears, tamarins focus more on insects. By late afternoon, they move to their night dens. Tamarin groups use hollow tree cavities, dense vines or epiphytes as sleeping sites. Sites that are between 11 and 15 m (36 and 49 ft) off the ground are preferred. The golden lion tamarin tends to be active earlier and retire later in the warmer, wetter times of the years as the days are longer. During drier times, it forages for insects longer as they become scarcer.Golden lion tamarins are characterized by using manipulative foraging under tree barks and epiphytic bromeliads. Their sites of foraging are usually distributed around their home ranges, which are large territories (averaging 123 hectares) in which multiple foraging sites are located, to find sufficient resources over long periods of time. These areas are sufficient enough in size so that even if there is overlap in between the home range of two different groups, the interactions are minimal due to the distribution of the foraging sites (they spend 50% of their time in approximately 11% of their home range).
+
+The golden lion tamarin has a diverse, omnivorous diet consisting of fruits, flowers, nectar, bird eggs, insects and small vertebrates. They rely on microhabitats for foraging and other daily activities and tamarins will use bromeliads, palm crowns, palm leaf sheaths, woody crevices, lianas, vine tangles, tree bark, rotten logs, and leaf litters. The golden lion tamarin uses its fingers to extract prey from crevices, under leaves, and in dense growth; a behavior known as micromanipulation. It is made possible by elongated hands and fingers. Insects make up to 10–15% of its diet. Much of the rest is made of small, sweet, pulpy fruits. During the rainy season, the golden lion tamarin mainly eats fruit; however, during drier times, it must eat more of other foods like nectar and gums. Small vertebrates are also consumed more at these times as insects become less abundant.
+
+
+=== Social structure ===
+
+Golden lion tamarins are social and groups typically consist of 2-8 members. These groups usually consist of one breeding adult male and female but may also have 2–3 males and one female or the reverse. Other members include subadults, juveniles and infants of either sex.  These individuals are typically the offspring of the adults. When there is more than one breeding adult in a group, one is usually dominant over the other and this is maintained through aggressive behavior. The dominance relationship between males and females depends on longevity in the group. A newly immigrated male is subordinate to the resident adult female who inherited her rank from her mother. Both males and females may leave their natal group at the age of four, however females may replace their mothers as the breeding adult, if they die, which will lead to the dispersal of the breeding male who is likely her father. This does not happen with males and their fathers. Dispersing males join groups with other males and remain in them until they find an opportunity to immigrate to a new group. The vast majority of recruits to groups are males. A male may find an opportunity to enter into a group when the resident male dies or disappears. Males may also aggressively displace resident males from their group; this is usually done by two immigrant males who are likely brothers.  When this happens, only one of the new males will be able to breed and will suppress the reproduction of the other. A resident male may also leave a vacancy when his daughter becomes the breeding female and he must disperse to avoid inbreeding. Golden lion tamarins are highly territorial and groups will defend their home range boundaries and resources from other groups.Tamarins emit "whine" and "peep" calls, which are associated with alarm and alliances respectively. "Clucks" are made during foraging trips or during aggressive encounters, whether directed at conspecifics or predators. "Trills" are used to communicate over long distances to give away an individual's position. "Rasps" or "screeches" are usually associated with playful behavior. Tamarins communicate through chemicals marked throughout their territories. Reproductive males and females scent mark the most and their non-reproductive counterparts rarely do so. Dominant males use scent marking to show their social status and may suppress the reproductive abilities of the other males.
+
+
+=== Reproduction ===
+
+The mating system of the golden lion tamarin is largely monogamous. When there are two adult males in a group only one of them will mate with the female. There are cases of a male mating with two females, usually a mother and daughter. Reproduction is seasonal and depends on rainfall. Mating is at its highest at the end of the rainy season between late March to mid-June and births peak during the September–February rains. Females are sexually mature between the ages of 15–20 months but it isn't until they are 30 months old that they can reproduce. Only dominant females can reproduce and will suppress the reproduction of the other females in the group. Males may reach puberty by 28 months. Tamarins have a four-month gestation period. Golden lion tamarin groups exhibit cooperative rearing of the infants. This is due to the fact that tamarins commonly give birth to twins and, to a lesser extent, triplets and quadruplets. A mother is not able to provide for her litter and needs the help of the other members of the group. The younger members of the groups may lose breeding opportunities but they gain parental experience in helping to rear their younger siblings. In their first 4 weeks, the infants are completely dependent on their mother for nursing and carrying. By week five, the infants spend less time on their mother’s back and begin to explore their surroundings. Young reach their juvenile stage at 17 weeks and will socialize other group members. The sub-adult phase is reached at 14 months, when a tamarin first displays adult behaviors.
+
+
+=== Ecosystem roles ===
+
+The golden lion tamarin has a mutualistic interaction with 96 species of plants found in the Atlantic Forest. This interaction is based on seed dispersal and food sources for the tamarins. The tamarins show repeat visits to those plants with abundant resources. They tend to move around their territories, and therefore, seeds are dispersed to areas far from the parent shadow, which is ideal for germination. Their seed distribution is important to forest regeneration, and genetic variability and survival of endangered plant species.

+=== Predation ===
+A study has shown that increased predation has caused significant decreases in the population numbers. A survey conducted in 1992 found the number of wild population of golden lion tamarins to be 562 individuals in 109 groups. Currently, the average group size includes 3.6 to 5.7 individuals and densities from 0.39 groups/km to 2.35 groups/km. These predatory attacks occur at the golden lion tamarin sleeping sites. The predators make those sleeping sites, which are mainly tree holes (about 63.6%), larger in order to attack the golden lion tamarins, sometimes wiping out the entire family. The preferred sleeping sites of most golden lion tamarins are tree holes in living trees next to other larger trees with a small percentage of canopy cover. These sleeping sites not only provide a place for sleep, but also offer protection and easy access to foraging sites. Most of the tree holes are lower to the ground, so they are easier to enter. Tree holes that are located in living trees are drier, warmer, and have a lower number of insects and therefore a decreased percentage of transmitted diseases. A smaller percentage of canopy coverage allows the golden lion tamarins to detect the predators faster, and being surrounded by other large trees allows them access to escape routes. Due to degradation of their habitats, there are fewer trees that can support entire social groups and some have to resort to using bamboo (17.5%), vine tangles (9.6%), and bromeliads (4.7%) as a sleeping site, making them more susceptible to predators. Golden lion tamarins are known to use different den sites, but do not change sites often. They are more likely to reuse secure sites that will offer protection. However, the disadvantage of doing so is that predators are able to learn where these sites are located. Golden lion tamarins also scent mark their den holes, so they can quickly return to them in the afternoon time when predators are most active. While excessive scent makes it easier for golden lion tamarins to find their sleeping sites, it also helps predators locate their prey. Moreover, increased deforestation has decreased habitat space, providing predators easy access to their prey, causing a decline in the golden lion tamarin population.
+
+
+== Conservation ==
+
+Threats to the golden lion tamarin population include illegal logging, poaching, mining, urbanization, deforestation, pet trading, and infrastructure development and the introduction of alien species. In 1969, the number of individuals in the Atlantic Forest was found to have dropped to a low of 150 individuals. In 1975 the golden lion tamarin was listed under Appendix I of CITES, given to animals threatened with extinction that may be or are being affected by trade. The species was listed as Endangered by the IUCN in 1982, and by 1984 the National Zoological Park in Washington, D.C. and the World Wide Fund for Nature, through the Golden Lion Tamarin Association, began a reintroduction programme from 140 zoos worldwide. Despite the success of the project, the IUCN classification rose to Critically Endangered in 1996. By 2003 the successful establishment of a new population at União Biological Reserve enabled downgrading the species to endangered, but the IUCN warns that extreme habitat fragmentation from deforestation means the wild population has little potential for any further expansion. In an attempt to curb the golden lion tamarin's precipitous decline, several conservation programs have been undertaken. The intent is to strengthen the wild population and maintain a secure captive population in zoos worldwide. The survival rate of re-introduced animals has been encouraging, but destruction of unprotected habitat continues.
+
+
+=== Reintroduction ===
+Because of the extensive habitat loss of the golden lion tamarin, the wild population reached endangered status in the early 1980s. Beginning in 1983, there has been a huge effort on behalf of scientists and conservationists to reintroduce captive-born golden lion tamarins back into the wild. With the help of the Brazilian government, conservationists established the Poço das Antas Biological Reserve and the União Biological Reserve as sites for reintroduction. The goals of the reintroduction process include increasing the size as well as the genetic diversity of the wild population, increasing the available range to better encompass the historic range of the tamarins in Brazil, and widening the scope of public awareness and education programs.The first step of reintroduction begins with zoo free ranging programs, where tamarins have access to explore the entire zoo. However, they are kept on zoo grounds by the presence of a nest box, an ice box like container where their food is kept.  When the tamarins are reintroduced in Poço das Antas Biological Reserve, they require a large amount of post-release training and veterinary care. For the first 6–18 months the reintroduced groups are monitored. Additionally, 1-2 tamarins from each group are radio collared to allow careful monitoring, and all reintroduced tamarins are tattooed and dye marked for easy identification.
+
+
+=== Translocation ===
+Secondly, in an effort to save the golden lion tamarins from extinction, some of the golden lion tamarins have been removed from small, isolated unsafe forests and placed into a larger, protected forest; specifically they were moved to União Biological Reserve and Poço das Antas reserve. This effort to move the golden lion tamarins into União Biological Reserve in Brazil began in 1991. The golden lion tamarins faced the potential of getting new diseases that they had not been previously exposed to. Many were exposed to callitrichid hepatitis, and contracted the disease.Despite the challenge of illness, the forty-two translocated golden lion tamarins' population grew to over 200 in União Biological Reserve. The number of wild golden lion tamarins is now up in the thousands in all reserves and ranches combined in Brazil. These numbers were once down in the 200s in 1991. By 2025, the number of golden lion tamarins that are protected is projected to be greater than 2000.
+
+
+=== Effects of habitat loss ===
+Golden lion tamarins are native to the Atlantic Forest of Brazil. Their original habitat was located from the southern part of the state of Rio de Janeiro to the southern part of the state of Espirito Santo. However, deforestation of Atlantic Forest for commercial purposes, predation, and capture of the golden lion tamarins for animal trade and sale as pets has limited their population to about five municipalities across Rio de Janeiro. Most of the population is now found in the Poco des Antas Biological Reserve in Rio de Janeiro.However, due to the deforestation and fragmentation of the Atlantic forest, their home ranges have decreased in size. The decrease in size has been reported in terms of fragmentation, and today the forest consists of thousands of fragments equaling only 8% of its former size. This directly affects their areas of foraging and subsequently, the amount of resources available.
+
+
+==== Effect on juvenile behavior ====
+The habitat of the tamarins also affects their behavior and social interactions. For example, the type of trees present has a significant effect on the behavior of juvenile golden lion tamarins. Their juvenile behavior is characterized by social play between individuals of different ages and species. This is a key aspect of their social, cognitive and motor skill development, and it influences their behavior when facing competition and predators; how they play mirrors the way they act when facing predatory or competitive interactions. Social play is observed more in large branches (>10 cm) and vine tangles (4m above ground), which is considered safe for them, as they are less vulnerable to predators, compared to play in the dangerous areas including canopy branches and the forest floor. Therefore, deforestation affects the diversity in the forest and decreases the "safe" areas for play for the juvenile tamarins. As a result, play decreases and therefore the development of learned survivorship behaviors does as well. Also, if play is observed in the dangerous areas, the individuals are more exposed to predators, leading to a population decline; which resembles the effect of predation on their sleeping sites. The exposure to predation not only affects the juvenile tamarins but the adults as well, since it has been observed that play happens in the center of the group for protection of the young.
+
+
+==== Increase in inbreeding ====
+Additionally, this deforestation and fragmentation also leads to demographic instabilities, and an increased probability of inbreeding, consequently leading to inbreeding depression and a population decline. In the case of inbreeding, the problem lies in the increase of the isolated fragments where golden lion tamarins live. Inbreeding leads to low levels of genetic diversity and has a negative effect on survivorship; inbred offspring have a lower survivorship than non-inbred offspring. Fragmentation leads to a decline in dispersal and as a result, a decline in breeding with individuals of other groups. Consequently, inbreeding depression is observed in these populations. With delay breeding, the decrease and shortage of territory puts pressure on golden lion tamarins to disperse in order to find necessary resources and areas suitable for their survival. However, dispersal is risky and requires a lot of energy that could have been used for reproduction instead.

+The Bali myna (Leucopsar rothschildi), also known as Rothschild's mynah, Bali starling, or Bali mynah, locally known as jalak Bali, is a medium-sized (up to 25 cm (9.8 in) long), stocky myna, almost wholly white with a long, drooping crest, and black tips on the wings and tail. The bird has blue bare skin around the eyes, greyish legs and a yellow bill. Both sexes are similar. It is critically endangered and in 2018, fewer than 100 adults were assumed to exist in the wild.
+
+
+== Taxonomy and systematics ==
+The first scientific description of the Bali myna was made in 1912. Placed in the monotypic genus Leucopsar, it appears to be most closely related to Sturnia and the brahminy starling which was initially placed in Sturnus then later moved by a study in 2008 to Sturnia, as Sturnus as delimited was highly paraphyletic. The specific epithet commemorates the British ornithologist Lord Rothschild.
+
+
+== Description ==
+
+The Bali myna is a medium-large bird around 25 centimetres (9.8 in) in length. It is almost wholly white with a long, drooping crest, black wing-tips and tail tip. It has a yellow bill with blue bare skin around the eyes and legs. The black-winged starling (Sturnus melanopterus), a similar species, has a shorter crest and a much larger area of black on wings and tail, plus a yellow eye-ring (without feathers) and legs.
+
+
+== Distribution and habitat ==
+The Bali myna is restricted to the island of Bali (and its offshore islands) in Indonesia, where it is the island's only endemic vertebrate species. In 1991, the bird was designated the faunal emblem of Bali. Featured on the Indonesian 200 rupiah coin, its local name is jalak Bali (Balinese script: ᬚᬮᬓ᭄ᬩᬮᬶ).
+
+
+== Behaviour and ecology ==
+
+In its natural habitat it is inconspicuous, using tree tops for cover and–unlike other starlings–usually coming to the ground only to drink or to find nesting materials; this would seem to be an adaptation to its noticeability to predators when out in the open. The Bali mynah often gathers in groups when it is young to better locate food and watch out for predators. The vocalizations are a variety of sharp chattering calls and an emphatic tweet.The Bali myna's diet includes fruit, seeds, worms and insects.
+
+
+=== Breeding ===
+During the breeding season (the rainy season of Bali), males attract females by calling loudly and bobbing up and down. The birds nest in tree cavities, with the female laying and incubating two or three eggs. Both males and females bring food to the nest for chicks after hatching.
+
+
+== Status and conservation ==
+
+The Bali myna is critically endangered, and the wild population has been close to extinction since at least 1994. As of 2015, less than 100 adults are assumed to exist in the wild, with about 1,000 believed to survive in captivity. The Bali myna is listed in Appendix I of CITES. Trade even in captive-bred specimens is strictly regulated and the species is not generally available legally to private individuals. However, experienced aviculturalists may become affiliated with captive-breeding programs, allowing them to legally keep this species. The number of captive birds bought on the black market is estimated to be twice the number of legally acquired individuals in the captive breeding programs.In 2018, there were three locations on Bali where the birds existed in the wild: the West Bali National Park; Bali's small island of Nusa Penida and Begawan Foundation's breeding and release site at Melinggih Kelod, Payangan.
+
+
+=== Bali myna breeding program ===
+A "breeding loan" involves 12 breeders who each received 15 male and 15 female from the Association of Starling Conservationists from Bogor, West Java. As collateral every breeder should put up a cow in case all the birds died. The breeders are obliged to release 10 percent of the brood into the national park and the rest can be sold off privately.
+
+
+=== West Bali National Park ===
+There were an estimated 350 birds in the West Bali National Park in the 1980s. During the 1990s over 400 cage-bred birds were released into the park to increase their numbers. But by 2005, the park authorities estimated the number to have fallen to less than 10. This decline was caused primarily by poachers responding to the lucrative demand for rare birds in the caged bird market.
+
+
+=== Nusa Penida island ===
+
+A population of Bali mynas now exists on the island of Nusa Penida and its sister islands of Nusa Ceningan, Nusa Lembongan, which are 14 km off the south east coast of Bali. The islands have been transformed into an unofficial bird sanctuary by
+Friends of National Parks Foundation (FNPF), an Indonesian NGO based in Bali. This was achieved by FNPF working for many years with the 40+ villages on the islands and persuading every village to pass a traditional Balinese village regulation to protect birds, and effectively removing the threat of poachers. Since then, FNPF has rehabilitated and released several endangered birds onto the island of Nusa Penida, including many Bali mynas supplied from multiple breeders.The Begawan Foundation began its Bali Starling Breeding Program in Begawan Giri in 1999 with two pairs, which had grown to a population of 97 in 2005. A release program was started on Nusa Penida, where 64 individuals were released in 2006 and 2007. Monitoring of the released birds suggests that their numbers had increased to +100 by 2009, and had spread across Penida, with small numbers also breeding on Ceningan and Lembongan. A number of further captive-bred individuals have since been rewilded, including 6 individuals on neighboring Nusa Lembongan. The foundation expects to release approximately 10 Bali mynas each year. The birds will continue to be sourced from different breeders to increase the genetic diversity of the growing wild population on Nusa Penida. Begawan Foundation field staff have monitored the released birds on a daily basis since their release and have a dedicated Field Officer since 2010. Findings are regularly reported to the Forestry Department, with photos and films taken of the birds' activities.
+
+However, according to an audit undertaken by Begawan Foundation on both Nusa Penida and Nusa Lembongan in February and March 2015, less than 15 birds were seen to be flying in the wild. Calculations undertaken suggest that by 2015, even taking natural predation and death of older birds into account, there should be at least 200 birds flying on Nusa Penida today, indicating that illegal wildlife trade is heavily impacting the population.
+
+
+=== Sibang, Central Bali ===
+
+In 2010, Begawan Foundation made a decision to move all its captive breeding Bali starlings from Nusa Penida to a new site at Sibang, near Ubud. The breeding program then recommenced with the aim to research new release sites close by. During 2011, a total of 23 Bali starlings were donated to BF's breeding program. Three birds were donated by Jurong Bird Park, and 20 came from a variety of zoos across Europe, members of the European Endangered Species Program, whose contributions of birds meant that new genetic lines would be introduced when the imported birds were paired with the local birds held at the breeding centre in Bali.In November 2012, Begawan Foundation released four pairs of Bali starlings at its breeding site in Sibang. These birds were observed and their daily habits recorded by staff of the Foundation and students of the adjacent Green School. A program of conservation was undertaken with the local villages prior to the release and has the full support of the King of Sibang. Each bird has been ringed in order to identify it as it adapts to life in the wild. As this was a soft release, the birds often take the opportunity to return to the breeding site to find food and water. However, it is evident that new sources of fruit and a variety of insects are available in the immediate vicinity that provide a full and healthy diet for these birds and their offspring.In 2014, there were three releases by Begawan Foundation at their site in Sibang. Three male birds and one female were released in April, with support from the local community. In June, Dr. Jane Goodall, during her visit to Bali, assisted in the release of two Bali starlings.
+
+
+=== Melinggih Kelod, Payangan ===
+In late 2017, Begawan Foundation decided to concentrate its programs in Melinggih Kelod, Payangan, north of Ubud. A community-based conservation program began in the village in late 2017, providing local residents with the opportunity to breed Bali Starlings, and to be able to release F2 generation offspring within two years, and again in subsequent years. It is also envisaged that the community will be responsible for the safety of the Bali Starlings in the wild through serious monitoring and village traditional law enforcement. The Village officiated an “awik-awik” (local law) in November 2018, which has been signed by the Village Head as well as the Kelians (heads) of the banjars (village sections). The local law states that shooting/trapping/hunting the Bali Starling or any other protected wildlife in the area is prohibited. Any person from the community that is caught doing any of the above will pay a penalty of Rp10,000,000.
+The Foundation also released a number of Starlings in late 2018, creating a wild flock of Bali Starlings in the Village, which is protected by the community. It is hoped that the soft releases will give the offspring the chance to reproduce in the wild and that a program of eco-tourism can be developed to provide income for the village.
+Along with the community-based conservation program in Melinggih Kelod Village, the Foundation's Breeding and Release Centre has been relocated and is now centred in Banjar Begawan, one of the districts in the Village. This centre is open to the local community and the general public.

+The lion (Panthera leo) is a large cat of the genus Panthera native to Africa and India. It has a muscular, broad-chested body, short, rounded head, round ears, and a hairy tuft at the end of its tail. It is sexually dimorphic; adult male lions are larger than females and have a prominent mane. It is a social species, forming groups called prides. A lion's pride consists of a few adult males, related females, and cubs. Groups of female lions usually hunt together, preying mostly on large ungulates. The lion is an apex and keystone predator; although some lions scavenge when opportunities occur and have been known to hunt humans, the species typically does not actively seek out and prey on humans.
+The lion inhabits grasslands, savannas and shrublands. It is usually more diurnal than other wild cats, but when persecuted, it adapts to being active at night and at twilight. During the Neolithic period, the lion ranged throughout Africa and Eurasia from Southeast Europe to India, but it has been reduced to fragmented populations in sub-Saharan Africa and one population in western India. It has been listed as Vulnerable on the IUCN Red List since 1996 because populations in African countries have declined by about 43% since the early 1990s. Lion populations are untenable outside designated protected areas. Although the cause of the decline is not fully understood, habitat loss and conflicts with humans are the greatest causes for concern.
+One of the most widely recognised animal symbols in human culture, the lion has been extensively depicted in sculptures and paintings, on national flags, and in contemporary films and literature. Lions have been kept in menageries since the time of the Roman Empire and have been a key species sought for exhibition in zoological gardens across the world since the late 18th century. Cultural depictions of lions were prominent in Ancient Egypt, and depictions have occurred in virtually all ancient and medieval cultures in the lion's historic and current range.
+
+
+== Etymology ==
+The English word lion is derived via Anglo-Norman liun from Latin leōnem (nominative: leō), which in turn was a borrowing from Ancient Greek λέων léōn. The Hebrew word לָבִיא lavi may also be related. The generic name Panthera is traceable to the classical Latin word 'panthēra' and the ancient Greek word πάνθηρ 'panther'.
+
+
+== Taxonomy ==
+
+Felis leo was the scientific name used by Carl Linnaeus in 1758, who described the lion in his work Systema Naturae. The genus name Panthera was coined by Lorenz Oken in 1816. Between the mid-18th and mid-20th centuries, 26 lion specimens were described and proposed as subspecies, of which 11 were recognised as valid in 2005. They were distinguished mostly by the size and colour of their manes and skins.
+
+
+=== Subspecies ===
+
+In the 19th and 20th centuries, several lion type specimens were described and proposed as subspecies, with about a dozen recognised as valid taxa until 2017. Between 2008 and 2016, IUCN Red List assessors used only two subspecific names: P. l. leo for African lion populations, and P. l. persica for the Asiatic lion population. In 2017, the Cat Classification Task Force of the Cat Specialist Group revised lion taxonomy, and recognises two subspecies based on results of several phylogeographic studies on lion evolution, namely:
+P. l. leo (Linnaeus, 1758) − the nominate lion subspecies includes the Asiatic lion, the regionally extinct Barbary lion, and lion populations in West and northern parts of Central Africa. Synonyms include P. l. persica (Meyer, 1826), P. l. senegalensis (Meyer, 1826), P. l. kamptzi (Matschie, 1900), and P. l. azandica (Allen, 1924). Multiple authors referred to it as 'northern lion' and 'northern subspecies'.
+P. l. melanochaita (Smith, 1842) − includes the extinct Cape lion and lion populations in East and Southern African regions. Synonyms include P. l. somaliensis (Noack 1891), P. l. massaica (Neumann, 1900), P. l. sabakiensis (Lönnberg, 1910), P. l. bleyenberghi (Lönnberg, 1914), P. l. roosevelti (Heller, 1914), P. l. nyanzae (Heller, 1914), P. l. hollisteri (Allen, 1924), P. l. krugeri (Roberts, 1929), P. l. vernayi (Roberts, 1948), and P. l. webbiensis (Zukowsky, 1964). It has been referred to as 'southern subspecies' and 'southern lion'.However, there seems to be some degree of overlap between both groups in northern Central Africa. DNA analysis from a more recent study indicates, that Central African lions are derived from both northern and southern lions, as they cluster with P. leo leo in mtDNA-based phylogenies whereas their genomic DNA indicates a closer relationship with P. leo melanochaita.Lion samples from some parts of the Ethiopian Highlands cluster genetically with those from Cameroon and Chad, while lions from other areas of Ethiopia cluster with samples from East Africa. Researchers therefore assume Ethiopia is a contact zone between the two subspecies. Genome-wide data of a wild-born historical lion sample from Sudan showed that it clustered with P. l. leo in mtDNA-based phylogenies, but with a high affinity to P. l. melanochaita. This result suggested that the taxonomic position of lions in Central Africa may require revision.
+
+
+=== Fossil records ===
+
+Other lion subspecies or sister species to the modern lion existed in prehistoric times:
+P. l. sinhaleyus was a fossil carnassial excavated in Sri Lanka, which was attributed to a lion. It is thought to have become extinct around 39,000 years ago.
+P. leo fossilis was larger than the modern lion and lived in the Middle Pleistocene. Bone fragments were excavated in caves in the United Kingdom, Germany, Italy and Czech Republic.
+P. spelaea, or the cave lion, lived in Eurasia and Beringia during the Late Pleistocene. It became extinct due to climate warming or human expansion latest by 11,900 years ago. Bone fragments excavated in European, North Asian, Canadian and Alaskan caves indicate that it ranged from Europe across Siberia into western Alaska. It likely derived from P. fossilis, and was genetically isolated and highly distinct from the modern lion in Africa and Eurasia. It is depicted in Paleolithic cave paintings, ivory carvings, and clay busts.
+P. atrox, or the American lion, ranged in the Americas from Canada to possibly Patagonia. It arose when a cave lion population in Beringia became isolated south of the Cordilleran Ice Sheet about 370,000 years ago. A fossil from Edmonton dates to 11,355 ± 55 years ago.
+
+
+=== Evolution ===
+
+The Panthera lineage is estimated to have genetically diverged from the common ancestor of the Felidae around 9.32 to 4.47 million years ago to 11.75 to 0.97 million years ago,
+and the geographic origin of the genus is most likely northern Central Asia.
+Results of analyses differ in the phylogenetic relationship of the lion; it was thought to form a sister group with the jaguar (P. onca) that diverged 3.46 to 1.22 million years ago, but also with the leopard (P. pardus) that diverged 3.1 to 1.95 million years ago to 4.32 to 0.02 million years ago. Hybridisation between lion and snow leopard (P. uncia) ancestors possibly continued until about 2.1 million years ago. The lion-leopard clade was distributed in the Asian and African Palearctic since at least the early Pliocene. The earliest fossils recognisable as lions were found at Olduvai Gorge in Tanzania and are estimated to be up to 2 million years old.Estimates for the divergence time of the modern and cave lion lineages range from 529,000 to 392,000 years ago based on mutation rate per generation time of the modern lion. There is no evidence for gene flow between the two lineages, indicating that they did not share the same geographic area. The Eurasian and American cave lions became extinct at the end of the last glacial period without mitochondrial descendants on other continents. The modern lion was probably widely distributed in Africa during the Middle Pleistocene and started to diverge in sub-Saharan Africa during the Late Pleistocene. Lion populations in East and Southern Africa became separated from populations in West and North Africa when the equatorial rainforest expanded 183,500 to 81,800 years ago. They shared a common ancestor probably between 98,000 and 52,000 years ago. Due to the expansion of the Sahara between 83,100 and 26,600 years ago, lion populations in West and North Africa became separated. As the rainforest decreased and thus gave rise to more open habitats, lions moved from West to Central Africa. Lions from North Africa dispersed to southern Europe and Asia between 38,800 and 8,300 years ago.Extinction of lions in southern Europe, North Africa and the Middle East interrupted gene flow between lion populations in Asia and Africa. Genetic evidence revealed numerous mutations in lion samples from East and Southern Africa, which indicates that this group has a longer evolutionary history than genetically less diverse lion samples from Asia and West and Central Africa. A whole genome-wide sequence of lion samples showed that samples from West Africa shared alleles with samples from Southern Africa, and samples from Central Africa shared alleles with samples from Asia. This phenomenon indicates that Central Africa was a melting pot of lion populations after they had become isolated, possibly migrating through corridors in the Nile Basin during the early Holocene.
+
+
+=== Hybrids ===
+
+In zoos, lions have been bred with tigers to create hybrids for the curiosity of visitors or for scientific purpose. The liger is bigger than a lion and a tiger, whereas most tigons are relatively small compared to their parents because of reciprocal gene effects. The leopon is a hybrid between a lion and leopard.
+
+
+== Description ==
+
+The lion is a muscular, broad-chested cat with a short, rounded head, a reduced neck and round ears. Its fur varies in colour from light buff to silvery grey, yellowish red and dark brown. The colours of the underparts are generally lighter. A new-born lion has dark spots, which fade as the cub reaches adulthood, although faint spots often may still be seen on the legs and underparts. The lion is the only member of the cat family that displays obvious sexual dimorphism. Males have broader heads and a prominent mane that grows downwards and backwards covering most of the head, neck, shoulders, and chest. The mane is typically brownish and tinged with yellow, rust and black hairs.The tail of all lions ends in a dark, hairy tuft that in some lions conceals an approximately 5 mm (0.20 in)-long, hard "spine" or "spur" that is formed from the final, fused sections of tail bone. The functions of the spur are unknown. The tuft is absent at birth and develops at around 5+1⁄2 months of age. It is readily identifiable by the age of seven months.Of the living felid species, the lion is rivaled only by the tiger in length, weight, and height at the shoulder. Its skull is very similar to that of the tiger, although the frontal region is usually more depressed and flattened, and has a slightly shorter postorbital region and broader nasal openings than those of the tiger. Due to the amount of skull variation in the two species, usually only the structure of the lower jaw can be used as a reliable indicator of species.Skeletal muscles of the lion make up 58.8% of its body weight and represents the highest percentage of muscles among mammals.
+
+
+=== Size ===
+The size and weight of adult lions varies across global range and habitats. Accounts of a few individuals that were larger than average exist from Africa and India.
+
+
+=== Mane ===
+
+The male lion's mane is the most recognisable feature of the species. It may have evolved around 320,000–190,000 years ago. It starts growing when lions are about a year old. Mane colour varies and darkens with age; research shows its colour and size are influenced by environmental factors such as average ambient temperature. Mane length apparently signals fighting success in male–male relationships; darker-maned individuals may have longer reproductive lives and higher offspring survival, although they suffer in the hottest months of the year. The presence, absence, colour and size of the mane are associated with genetic precondition, sexual maturity, climate and testosterone production; the rule of thumb is that a darker, fuller mane indicates a healthier animal. In Serengeti National Park, female lions favour males with dense, dark manes as mates. Cool ambient temperature in European and North American zoos may result in a heavier mane. Asiatic lions usually have sparser manes than average African lions.Almost all male lions in Pendjari National Park are either maneless or have very short manes. Maneless lions have also been reported in Senegal, in Sudan's Dinder National Park and in Tsavo East National Park, Kenya. The original male white lion from Timbavati in South Africa was also maneless. The hormone testosterone has been linked to mane growth; castrated lions often have little to no mane because the removal of the gonads inhibits testosterone production. Increased testosterone may be the cause of maned lionesses reported in northern Botswana.
+
+
+=== Colour variation ===
+
+The white lion is a rare morph with a genetic condition called leucism which is caused by a double recessive allele. It is not albino; it has normal pigmentation in the eyes and skin. White lions have occasionally been encountered in and around Kruger National Park and the adjacent Timbavati Private Game Reserve in eastern South Africa. They were removed from the wild in the 1970s, thus decreasing the white lion gene pool. Nevertheless, 17 births have been recorded in five prides between 2007 and 2015. White lions are selected for breeding in captivity. They have reportedly been bred in camps in South Africa for use as trophies to be killed during canned hunts.
+
+
+== Distribution and habitat ==
+
+African lions live in scattered populations across sub-Saharan Africa. The lion prefers grassy plains and savannahs, scrub bordering rivers and open woodlands with bushes. It rarely enters closed forests. On Mount Elgon, the lion has been recorded up to an elevation of 3,600 m (11,800 ft) and close to the snow line on Mount Kenya. Savannahs with an annual rainfall of 300 to 1,500 mm (12 to 59 in) make up the majority of lion habitat in Africa, estimated at 3,390,821 km2 (1,309,203 sq mi) at most, but remnant populations are also present in tropical moist forests in West Africa and montane forests in East Africa. The Asiatic lion now survives only in and around Gir National Park in Gujarat, western India. Its habitat is a mixture of dry savannah forest and very dry, deciduous scrub forest.
+
+
+=== Historical range ===
+In Africa, the range of the lion originally spanned most of the central African rainforest zone and the Sahara desert. In the 1960s, it became extinct in North Africa, except in the southern part of Sudan.In southern Europe and Asia, the lion once ranged in regions where climatic conditions supported an abundance of prey. In Greece, it was common as reported by Herodotus in 480 BC; it was considered rare by 300 BC and extirpated by AD 100. It was present in the Caucasus until the 10th century. It lived in Palestine until the Middle Ages, and in Southwest Asia until the late 19th century. By the late 19th century, it had been extirpated in most of Turkey. The last live lion in Iran was sighted in 1942 about 65 km (40 mi) northwest of Dezful, although the corpse of a lioness was found on the banks of the Karun river in Khūzestān Province in 1944. It once ranged from Sind and Punjab in Pakistan to Bengal and the Narmada River in central India.
+
+
+== Behaviour and ecology ==
+Lions spend much of their time resting; they are inactive for about twenty hours per day. Although lions can be active at any time, their activity generally peaks after dusk with a period of socialising, grooming and defecating. Intermittent bursts of activity continue until dawn, when hunting most often takes place. They spend an average of two hours a day walking and fifty minutes eating.
+
+
+=== Group organisation ===
+
+The lion is the most social of all wild felid species, living in groups of related individuals with their offspring. Such a group is called a "pride". Groups of male lions are called "coalitions". Females form the stable social unit in a pride and do not tolerate outside females. Membership changes only with the births and deaths of lionesses, although some females leave and become nomadic. The average pride consists of around 15 lions, including several adult females and up to four males and their cubs of both sexes. Large prides, consisting of up to 30 individuals, have been observed. The sole exception to this pattern is the Tsavo lion pride that always has just one adult male. Male cubs are excluded from their maternal pride when they reach maturity at around two or three years of age.Some lions are "nomads" that range widely and move around sporadically, either in pairs or alone. Pairs are more frequent among related males who have been excluded from their birth pride. A lion may switch lifestyles; nomads can become residents and vice versa. Interactions between prides and nomads tend to be hostile, although pride females in estrus allow nomadic males to approach them. Males spend years in a nomadic phase before gaining residence in a pride. A study undertaken in the Serengeti National Park revealed that nomadic coalitions gain residency at between 3.5 and 7.3 years of age. In Kruger National Park, dispersing male lions move more than 25 km (16 mi) away from their natal pride in search of their own territory. Female lions stay closer to their natal pride. Therefore, female lions in an area are more closely related to each other than male lions in the same area.The area occupied by a pride is called a "pride area" whereas that occupied by a nomad is a "range". Males associated with a pride tend to stay on the fringes, patrolling their territory. The reasons for the development of sociality in lionesses—the most pronounced in any cat species—are the subject of much debate. Increased hunting success appears to be an obvious reason, but this is uncertain upon examination; coordinated hunting allows for more successful predation but also ensures non-hunting members reduce per capita calorific intake. Some females, however, take a role raising cubs that may be left alone for extended periods. Members of the pride tend to regularly play the same role in hunts and hone their skills. The health of the hunters is the primary need for the survival of the pride; hunters are the first to consume the prey at the site it is taken. Other benefits include possible kin selection, sharing food within the family, protecting the young, maintaining territory, and individual insurance against injury and hunger.Both males and females defend the pride against intruders, but the male lion is better-suited for this purpose due to its stockier, more powerful build. Some individuals consistently lead the defence against intruders, while others lag behind. Lions tend to assume specific roles in the pride; slower-moving individuals may provide other valuable services to the group. Alternatively, there may be rewards associated with being a leader that fends off intruders; the rank of lionesses in the pride is reflected in these responses. The male or males associated with the pride must defend their relationship with the pride from outside males who may attempt to usurp them.Asiatic lion prides differ in group composition. Male Asiatic lions are solitary or associate with up to three males, forming a loose pride while females associate with up to 12 other females, forming a stronger pride together with their cubs. Female and male lions associate only when mating. Coalitions of males hold territory for a longer time than single lions. Males in coalitions of three or four individuals exhibit a pronounced hierarchy, in which one male dominates the others and mates more frequently.
+
+
+=== Hunting and diet ===
+
+The lion is a generalist hypercarnivore and is considered to be both an apex and keystone predator due to its wide prey spectrum. Its prey consists mainly of ungulates weighing 190–550 kg (420–1,210 lb), particularly blue wildebeest, plains zebra, African buffalo, gemsbok and giraffe. They also hunt common warthog depending on availability, despite weighing less than the preferred weight range. In India, chital and sambar deer are the most common wild prey, while livestock contributes significantly to lion kills outside protected areas. They usually avoid fully grown adult elephants, rhinoceroses and hippopotamus and small prey like dik-dik, hyraxes, hares and monkeys. Unusual prey include porcupines and small reptiles. Lions kill other predators but seldom consume them.Young lions first display stalking behaviour at around three months of age, although they do not participate in hunting until they are almost a year old and begin to hunt effectively when nearing the age of two. Single lions are capable of bringing down zebra and wildebeest, while larger prey like buffalo and giraffe are riskier. In Chobe National Park, large prides have been observed hunting African bush elephants up to around 15 years old in exceptional cases, with the victims being calves, juveniles, and even subadults. In typical hunts, each lioness has a favoured position in the group, either stalking prey on the "wing", then attacking, or moving a smaller distance in the centre of the group and capturing prey fleeing from other lionesses. Males attached to prides do not usually participate in group hunting. Some evidence suggests, however, that males are just as successful as females; they are typically solo hunters who ambush prey in small bushland.Lions are not particularly known for their stamina. For instance, a lioness's heart comprises only 0.57% of her body weight and a male's is about 0.45% of his body weight, whereas a hyena's heart comprises almost 1% of its body weight. Thus, lions run quickly only in short bursts at about 48–59 km/h (30–37 mph) and need to be close to their prey before starting the attack. One study in 2018 recorded a lion running at a top speed of 74.1 km/h (46.0 mph). They take advantage of factors that reduce visibility; many kills take place near some form of cover or at night. The lion's attack is short and powerful; they attempt to catch prey with a fast rush and final leap. They usually pull it down by the rump and kill by a strangling bite to the throat. They also kill prey by enclosing its muzzle in their jaws. Male lions usually aim for the backs or hindquarters of rivals, rather than their necks.Lions typically consume prey at the location of the hunt but sometimes drag large prey into cover. They tend to squabble over kills, particularly the males. Cubs suffer most when food is scarce but otherwise all pride members eat their fill, including old and crippled lions, which can live on leftovers. Large kills are shared more widely among pride members. An adult lioness requires an average of about 5 kg (11 lb) of meat per day while males require about 7 kg (15 lb). Lions gorge themselves and eat up to 30 kg (66 lb) in one session. If it is unable to consume all of the kill, it rests for a few hours before continuing to eat. On hot days, the pride retreats to shade with one or two males standing guard. Lions defend their kills from scavengers such as vultures and hyenas.Lions scavenge on carrion when the opportunity arises, scavenging animals dead from natural causes such as disease or those that were killed by other predators. Scavenging lions keep a constant lookout for circling vultures, which indicate the death or distress of an animal. Most carrion on which both hyenas and lions feed upon are killed by hyenas rather than lions. Carrion is thought to provide a large part of lion diet.
+
+
+=== Predatory competition ===
+
+Lions and spotted hyenas occupy a similar ecological niche and compete for prey and carrion; a review of data across several studies indicates a dietary overlap of 58.6%. Lions typically ignore hyenas unless they are on a kill or are being harassed, while the latter tend to visibly react to the presence of lions with or without the presence of food. In the Ngorongoro crater, lions subsist largely on kills stolen from hyenas, causing them to increase their kill rate. In Botswana's Chobe National Park, the situation is reversed as hyenas there frequently challenge lions and steal their kills, obtaining food from 63% of all lion kills. When confronted on a kill, hyenas may either leave or wait patiently at a distance of 30–100 m (98–328 ft) until the lions have finished. Hyenas feed alongside lions and force them off a kill. The two species attack one another even when there is no food involved for no apparent reason. Lion predation can account for up to 71% of hyena deaths in Etosha National Park. Hyenas have adapted by frequently mobbing lions that enter their home ranges. When the lion population in Kenya's Masai Mara National Reserve declined, the spotted hyena population increased rapidly.Lions tend to dominate cheetahs and leopards, steal their kills and kill their cubs and even adults when given the chance. Cheetahs often lose their kills to lions or other predators. A study in the Serengeti ecosystem revealed that lions killed at least 17 of 125 cheetah cubs born between 1987 and 1990. Cheetahs avoid their competitors by hunting at different times and habitats. Leopards take refuge in trees, but lionesses occasionally attempt to climb up and retrieve their kills.Lions similarly dominate African wild dogs, taking their kills and slaying pups or adult dogs. Population densities of wild dogs are low in areas where lions are more abundant. However, there are a few reported cases of old and wounded lion falling prey to wild dogs. Nile crocodiles may also kill and eat lions, evidenced by the occasional lion claw found in crocodile stomachs.
+
+
+=== Reproduction and life cycle ===
+
+Most lionesses reproduce by the time they are four years of age. Lions do not mate at a specific time of year and the females are polyestrous. Like those of other cats, the male lion's penis has spines that point backward. During withdrawal of the penis, the spines rake the walls of the female's vagina, which may cause ovulation. A lioness may mate with more than one male when she is in heat. Generation length of the lion is about seven years. The average gestation period is around 110 days; the female gives birth to a litter of between one and four cubs in a secluded den, which may be a thicket, a reed-bed, a cave, or some other sheltered area, usually away from the pride. She will often hunt alone while the cubs are still helpless, staying relatively close to the den. Lion cubs are born blind, their eyes opening around seven days after birth. They weigh 1.2–2.1 kg (2.6–4.6 lb) at birth and are almost helpless, beginning to crawl a day or two after birth and walking around three weeks of age. To avoid a buildup of scent attracting the attention of predators, the lioness moves her cubs to a new den site several times a month, carrying them one-by-one by the nape of the neck.Usually, the mother does not integrate herself and her cubs back into the pride until the cubs are six to eight weeks old. Sometimes the introduction to pride life occurs earlier, particularly if other lionesses have given birth at about the same time. When first introduced to the rest of the pride, lion cubs lack confidence when confronted with adults other than their mother. They soon begin to immerse themselves in the pride life, however, playing among themselves or attempting to initiate play with the adults. Lionesses with cubs of their own are more likely to be tolerant of another lioness's cubs than lionesses without cubs. Male tolerance of the cubs varies—one male could patiently let the cubs play with his tail or his mane, while another may snarl and bat the cubs away.
+
+Pride lionesses often synchronise their reproductive cycles and communal rearing and suckling of the young, which suckle indiscriminately from any or all of the nursing females in the pride. The synchronisation of births is advantageous because the cubs grow to being roughly the same size and have an equal chance of survival, and sucklings are not dominated by older cubs. Weaning occurs after six or seven months. Male lions reach maturity at about three years of age and at four to five years are capable of challenging and displacing adult males associated with another pride. They begin to age and weaken at between 10 and 15 years of age at the latest.When one or more new males oust the previous males associated with a pride, the victors often kill any existing young cubs, perhaps because females do not become fertile and receptive until their cubs mature or die. Females often fiercely defend their cubs from a usurping male but are rarely successful unless a group of three or four mothers within a pride join forces against the male. Cubs also die from starvation and abandonment, and predation by leopards, hyenas and wild dogs. Up to 80% of lion cubs will die before the age of two. Both male and female lions may be ousted from prides to become nomads, although most females usually remain with their birth pride. When a pride becomes too large, however, the youngest generation of female cubs may be forced to leave to find their own territory. When a new male lion takes over a pride, adolescents both male and female may be evicted. Lions of both sexes may be involved in group homosexual and courtship activities. Males will also head-rub and roll around with each other before simulating sex together.
+
+
+=== Health and mortality ===
+
+Although adult lions have no natural predators, evidence suggests most die violently from attacks by humans or other lions. Lions often inflict serious injuries on members of other prides they encounter in territorial disputes or members of the home pride when fighting at a kill. Crippled lions and cubs may fall victim to hyenas and leopards or be trampled by buffalo or elephants. Careless lions may be maimed when hunting prey.Ticks commonly infest the ears, neck and groin regions of the lions. Adult forms of several tapeworm species of the genus Taenia have been isolated from lion intestines, having been ingested as larvae in antelope meat. Lions in the Ngorongoro Crater were afflicted by an outbreak of stable fly (Stomoxys calcitrans) in 1962, resulting in lions becoming emaciated and covered in bloody, bare patches. Lions sought unsuccessfully to evade the biting flies by climbing trees or crawling into hyena burrows; many died or migrated and the local population dropped from 70 to 15 individuals. A more recent outbreak in 2001 killed six lions.Captive lions have been infected with canine distemper virus (CDV) since at least the mid-1970s. CDV is spread by domestic dogs and other carnivores; a 1994 outbreak in Serengeti National Park resulted in many lions developing neurological symptoms such as seizures. During the outbreak, several lions died from pneumonia and encephalitis. Feline immunodeficiency virus and lentivirus also affect captive lions.
+
+
+=== Communication ===
+
+When resting, lion socialisation occurs through a number of behaviours; the animal's expressive movements are highly developed. The most common peaceful, tactile gestures are head rubbing and social licking, which have been compared with the role of allogrooming among primates. Head rubbing—nuzzling the forehead, face and neck against another lion—appears to be a form of greeting and is seen often after an animal has been apart from others or after a fight or confrontation. Males tend to rub other males, while cubs and females rub females. Social licking often occurs in tandem with head rubbing; it is generally mutual and the recipient appears to express pleasure. The head and neck are the most common parts of the body licked; this behaviour may have arisen out of utility because lions cannot lick these areas themselves.
+
+Lions have an array of facial expressions and body postures that serve as visual gestures. A common facial expression is the "grimace face" or flehmen response, which a lion makes when sniffing chemical signals and involves an open mouth with bared teeth, raised muzzle, wrinkled nose closed eyes and relaxed ears. Lions also use chemical and visual marking; males will spray and scrape plots of ground and objects within the territory.The lion's repertoire of vocalisations is large; variations in intensity and pitch appear to be central to communication. Most lion vocalisations are variations of growling, snarling, meowing and roaring. Other sounds produced include purring, puffing, bleating and humming. Roaring is used to advertise its presence. Lions most often roar at night, a sound that can be heard from a distance of 8 kilometres (5 mi). They tend to roar in a very characteristic manner starting with a few deep, long roars that subside into a series of shorter ones.
+
+
+== Conservation ==
+The lion is listed as Vulnerable on the IUCN Red List. The Indian population is listed on CITES Appendix I and the African population on CITES Appendix II.
+
+
+=== In Africa ===
+
+Several large and well-managed protected areas in Africa host large lion populations. Where an infrastructure for wildlife tourism has been developed, cash revenue for park management and local communities is a strong incentive for lion conservation. Most lions now live in East and Southern Africa; their numbers are rapidly decreasing, and fell by an estimated 30–50% in the late half of the 20th century. Primary causes of the decline include disease and human interference. In 1975, it was estimated that since the 1950s, lion numbers had decreased by half to 200,000 or fewer. Estimates of the African lion population range between 16,500 and 47,000 living in the wild in 2002–2004.In the Republic of the Congo, Odzala-Kokoua National Park was considered a lion stronghold in the 1990s. By 2014, no lions were recorded in the protected area so the population is considered locally extinct. The West African lion population is isolated from the one in Central Africa, with little or no exchange of breeding individuals. In 2015, it was estimated that this population consists of about 400 animals, including fewer than 250 mature individuals. They persist in three protected areas in the region, mostly in one population in the W A P protected area complex, shared by Benin, Burkina Faso and Niger. This population is listed as Critically Endangered. Field surveys in the WAP ecosystem revealed that lion occupancy is lowest in the W National Park, and higher in areas with permanent staff and thus better protection.A population occurs in Cameroon's Waza National Park, where between approximately 14 and 21 animals persisted as of 2009. In addition, 50 to 150 lions are estimated to be present in Burkina Faso's Arly-Singou ecosystem. In 2015, an adult male lion and a female lion were sighted in Ghana's Mole National Park. These were the first sightings of lions in the country in 39 years. In the same year, a population of up to 200 lions that was previously thought to have been extirpated was filmed in the Alatash National Park, Ethiopia, close to the Sudanese border.In 2005, Lion Conservation Strategies were developed for West and Central Africa, and or East and Southern Africa. The strategies seek to maintain suitable habitat, ensure a sufficient wild prey base for lions, reduce factors that lead to further fragmentation of populations, and make lion–human coexistence sustainable. Lion depredation on livestock is significantly reduced in areas where herders keep livestock in improved enclosures. Such measures contribute to mitigating human–lion conflict.
+
+
+=== In Asia ===
+
+The last refuge of the Asiatic lion population is the 1,412 km2 (545 sq mi) Gir National Park and surrounding areas in the region of Saurashtra or Kathiawar Peninsula in Gujarat State, India. The population has risen from approximately 180 lions in 1974 to about 400 in 2010. It is geographically isolated, which can lead to inbreeding and reduced genetic diversity. Since 2008, the Asiatic lion has been listed as Endangered on the IUCN Red List. By 2015, the population had grown to 523 individuals inhabiting an area of 7,000 km2 (2,700 sq mi) in Saurashtra. The Asiatic Lion Census conducted in 2017 recorded about 650 individuals.The presence of numerous human habitations close to the National Park results in conflict between lions, local people and their livestock. Some consider the presence of lions a benefit, as they keep populations of crop damaging herbivores in check. The establishment of a second, independent Asiatic lion population in Kuno Wildlife Sanctuary, located in Madhya Pradesh was planned but in 2017, the Asiatic Lion Reintroduction Project seemed unlikely to be implemented.
+
+
+=== Captive breeding ===
+
+Lions imported to Europe before the middle of the 19th century were possibly foremost Barbary lions from North Africa, or Cape lions from Southern Africa. Another 11 animals thought to be Barbary lions kept in Addis Ababa Zoo are descendants of animals owned by Emperor Haile Selassie. WildLink International in collaboration with Oxford University launched an ambitious International Barbary Lion Project with the aim of identifying and breeding Barbary lions in captivity for eventual reintroduction into a national park in the Atlas Mountains of Morocco. However, a genetic analysis showed that the captive lions at Addis Ababa Zoo were not Barbary lions, but rather closely related to wild lions in Chad and Cameroon.In 1982, the Association of Zoos and Aquariums started a Species Survival Plan for the Asiatic lion to increase its chances of survival. In 1987, it was found that most lions in North American zoos were hybrids between African and Asiatic lions. Breeding programs need to note origins of the participating animals to avoid cross-breeding different subspecies and thus reducing their conservation value. Captive breeding of lions was halted to eliminate individuals of unknown origin and pedigree. Wild-born lions were imported to American zoos from Africa between 1989 and 1995. Breeding was continued in 1998 in the frame of an African lion Species Survival Plan.About 77% of the captive lions registered in the International Species Information System in 2006 were of unknown origin; these animals might have carried genes that are extinct in the wild and may therefore be important to the maintenance of the overall genetic variability of the lion.
+
+
+== Interactions with humans ==
+
+
+=== In zoos and circuses ===
+
+Lions are part of a group of exotic animals that have been central to zoo exhibits since the late 18th century. Although many modern zoos are more selective about their exhibits, there are more than 1,000 African and 100 Asiatic lions in zoos and wildlife parks around the world. They are considered an ambassador species and are kept for tourism, education and conservation purposes. Lions can live over twenty years in captivity; for example, three sibling lions at the Honolulu Zoo lived to the age of 22 in 2007.The first European "zoos" spread among noble and royal families in the 13th century, and until the 17th century were called seraglios. At that time, they came to be called menageries, an extension of the cabinet of curiosities. They spread from France and Italy during the Renaissance to the rest of Europe. In England, although the seraglio tradition was less developed, lions were kept at the Tower of London in a seraglio established by King John in the 13th century; this was probably stocked with animals from an earlier menagerie started in 1125 by Henry I at his hunting lodge in Woodstock, Oxfordshire, where according to William of Malmesbury lions had been stocked.Lions were kept in cramped and squalid conditions at London Zoo until a larger lion house with roomier cages was built in the 1870s. Further changes took place in the early 20th century when Carl Hagenbeck designed enclosures with concrete "rocks", more open space and a moat instead of bars, more closely resembling a natural habitat. Hagenbeck designed lion enclosures for both Melbourne Zoo and Sydney's Taronga Zoo; although his designs were popular, the use of bars and caged enclosures prevailed in many zoos until the 1960s. In the late 20th century, larger, more natural enclosures and the use of wire mesh or laminated glass instead of lowered dens allowed visitors to come closer than ever to the animals; some attractions such as the Cat Forest/Lion Overlook of Oklahoma City Zoological Park placed the den on ground level, higher than visitors.Lion taming has been part of both established circuses and individual acts such as Siegfried & Roy. The practice began in the early 19th century by Frenchman Henri Martin and American Isaac Van Amburgh, who both toured widely and whose techniques were copied by a number of followers. Van Amburgh performed before Queen Victoria in 1838 when he toured Great Britain. Martin composed a pantomime titled Les Lions de Mysore ("the lions of Mysore"), an idea Amburgh quickly borrowed. These acts eclipsed equestrianism acts as the central display of circus shows and entered public consciousness in the early 20th century with cinema. In demonstrating the superiority of human over animal, lion taming served a purpose similar to animal fights of previous centuries. The ultimate proof of a tamer's dominance and control over a lion is demonstrated by the placing of the tamer's head in the lion's mouth. The now-iconic lion tamer's chair was possibly first used by American Clyde Beatty (1903–1965).
+
+
+=== Hunting and games ===
+
+Lion hunting has occurred since ancient times and was often a royal tradition, intended to demonstrate the power of the king over nature. Such hunts took place in a reserved area in front of an audience. The monarch was accompanied by his men and controls were put in place to increase their safety and ease of killing. The earliest surviving record of lion hunting is an ancient Egyptian inscription dated circa 1380 BC that mentions Pharaoh Amenhotep III killing 102 lions in ten years "with his own arrows". The Assyrian emperor Ashurbanipal had one of his lion hunts depicted on a sequence of palace reliefs c. 640 BC, known as the Lion Hunt of Ashurbanipal. Lions were also hunted during the Mughal Empire, where Emperor Jahangir is said to have excelled at it. In Ancient Rome, lions were kept by emperors for hunts, gladiator fights and executions.The Maasai people have traditionally viewed the killing of lions as a rite of passage. Historically, lions were hunted by individuals, however, due to reduced lion populations, elders discourage solo lion hunts. During the European colonisation of Africa in the 19th century, the hunting of lions was encouraged because they were considered pests and lion skins were sold for £1 each. The widely reproduced imagery of the heroic hunter chasing lions would dominate a large part of the century. Trophy hunting of lions in recent years has been met with controversy, notably with the killing of Cecil the lion in mid-2015.
+
+
+=== Man-eating ===
+
+Lions do not usually hunt humans but some (usually males) seem to seek them out. One well-publicised case is the Tsavo maneaters; in 1898, 28 officially recorded railway workers building the Kenya-Uganda Railway were taken by lions over nine months during the construction of a bridge in Kenya. The hunter who killed the lions wrote a book detailing the animals' predatory behaviour; they were larger than normal and lacked manes, and one seemed to suffer from tooth decay. The infirmity theory, including tooth decay, is not favoured by all researchers; an analysis of teeth and jaws of man-eating lions in museum collections suggests that while tooth decay may explain some incidents, prey depletion in human-dominated areas is a more likely cause of lion predation on humans. Sick or injured animals may be more prone to man-eating but the behaviour is not unusual, nor necessarily aberrant.Lions' proclivity for man-eating has been systematically examined. American and Tanzanian scientists report that man-eating behaviour in rural areas of Tanzania increased greatly from 1990 to 2005. At least 563 villagers were attacked and many eaten over this period. The incidents occurred near Selous National Park in Rufiji District and in Lindi Province near the Mozambican border. While the expansion of villages into bush country is one concern, the authors argue conservation policy must mitigate the danger because in this case, conservation contributes directly to human deaths. Cases in Lindi in which lions seize humans from the centres of substantial villages have been documented. Another study of 1,000 people attacked by lions in southern Tanzania between 1988 and 2009 found that the weeks following the full moon, when there was less moonlight, were a strong indicator of increased night-time attacks on people.According to Robert R. Frump, Mozambican refugees regularly crossing Kruger National Park, South Africa, at night are attacked and eaten by lions; park officials have said man-eating is a problem there. Frump said thousands may have been killed in the decades after apartheid sealed the park and forced refugees to cross the park at night. For nearly a century before the border was sealed, Mozambicans had regularly crossed the park in daytime with little harm.
+
+
+== Cultural significance ==
+
+The lion is one of the most widely recognised animal symbols in human culture. It has been extensively depicted in sculptures and paintings, on national flags, and in contemporary films and literature. It appeared as a symbol for strength and nobility in cultures across Europe, Asia and Africa, despite incidents of attacks on people. The lion has been depicted as "king of the jungle" and "king of beasts", and thus became a popular symbol for royalty and stateliness. The lion is also used as a symbol of sporting teams.
+
+
+=== Africa ===
+In sub-Saharan Africa, the lion has been a common character in stories, proverbs and dances, but rarely featured in visual arts. In some cultures, the lion symbolises power and royalty. In the Swahili language, the lion is known as simba which also means "aggressive", "king" and "strong". Some rulers had the word "lion" in their nickname. Sundiata Keita of the Mali Empire was called "Lion of Mali". The founder of the Waalo kingdom is said to have been raised by lions and returned to his people part-lion to unite them using the knowledge he learned from the lions.In parts of West Africa, lions symbolised the top class of their social hierarchies. In more heavily forested areas where lions were rare, the leopard represented the top of the hierarchy. In parts of West and East Africa, the lion is associated with healing and provides the connection between seers and the supernatural. In other East African traditions, the lion  represents laziness. In much of African folklore, the lion is portrayed as having low intelligence and is easily tricked by other animals.The ancient Egyptians portrayed several of their war deities as lionesses, which they revered as fierce hunters. Egyptian deities associated with lions include Sekhmet, Bast, Mafdet, Menhit, Pakhet and Tefnut. These deities were often connected with the sun god Ra and his fierce heat, and their dangerous power was invoked to guard people or sacred places. The sphinx, a figure with a lion's body and the head of a human or other creature, represented a pharaoh or deity who had taken on this protective role.

+=== Eastern world ===
+
+The lion was a prominent symbol in ancient Mesopotamia from Sumer up to Assyrian and Babylonian times, where it was strongly associated with kingship. Lions were among the major symbols of the goddess Inanna/Ishtar. The Lion of Babylon was the foremost symbol of the Babylonian Empire. The Lion of Judah is the biblical emblem of the tribe of Judah and the later Kingdom of Judah. Lions are frequently mentioned in the Bible, notably in the Book of Daniel, in which the eponymous hero refuses to worship King Darius and is forced to sleep in the lions' den where he is miraculously unharmed (Dan 6). In the Book of Judges, Samson kills a lion as he travels to visit a Philistine woman.(Judg 14).Indo-Persian chroniclers regarded the lion as keeper of order in the realm of animals. The Sanskrit word mrigendra signifies a lion as king of animals in general or deer in particular. Narasimha, the man-lion, is one of ten avatars of the Hindu god Vishnu. Singh is an ancient Indian vedic name meaning "lion", dating back over 2,000 years. It was originally used only by Rajputs, a Hindu Kshatriya or military caste but is used by millions of Hindu Rajputs and more than twenty million Sikhs today. The Lion Capital of Ashoka, erected by Emperor Ashoka in the 3rd century CE, depicts four lions standing back to back. It was made the National Emblem of India in 1950. The lion is also symbolic for the Sinhalese people, the term derived from the Sanskrit Sinhala, meaning "of lions" while a sword-wielding lion is the central figure on the national flag of Sri Lanka.The lion is a common motif in Chinese art; it was first used in art during the late Spring and Autumn period (fifth or sixth century BC) and became more popular during the Han Dynasty (206 BC – AD 220) when imperial guardian lions started to be placed in front of imperial palaces for protection. Because lions have never been native to China, early depictions were somewhat unrealistic; after the introduction of Buddhist art to China in the Tang Dynasty after the sixth century AD, lions were usually depicted wingless with shorter, thicker bodies and curly manes. The lion dance is a traditional dance in Chinese culture in which performers in lion costumes mimic a lion's movements, often with musical accompaniment from cymbals, drums and gongs. They are performed at Chinese New Year, the August Moon Festival and other celebratory occasions for good luck.
+
+
+=== Western world ===
+
+Lion-headed figures and amulets were excavated in tombs in the Greek islands of Crete, Euboea, Rhodes, Paros and Chios. They are associated with the Egyptian deity Sekhmet and date to the early Iron Age between the 9th and 6th centuries BC. The lion is featured in several of Aesop's fables, notably The Lion and the Mouse. The Nemean lion was symbolic in ancient Greece and Rome, represented as the constellation and zodiac sign Leo, and described in mythology, where it was killed and worn by the hero Heracles, symbolising victory over death. Lancelot and Gawain were also heroes slaying lions in the Middle Ages. In some medieval stories, lions were portrayed as allies and companions. "Lion" was the nickname of several medieval warrior-rulers with a reputation for bravery, such as Richard the Lionheart.Lions continue to appear in modern literature as characters including the messianic Aslan in the 1950 novel The Lion, the Witch and the Wardrobe and The Chronicles of Narnia series by C. S. Lewis, and the comedic Cowardly Lion in L. Frank Baum's 1900 The Wonderful Wizard of Oz. Lion symbolism was used from the advent of cinema; one of the most iconic and widely recognised lions is Leo, which has been the mascot for Metro-Goldwyn-Mayer studios since the 1920s. The 1966 film Born Free features Elsa the lioness and is based on the 1960 non-fiction book with the same title. The lion's role as king of the beasts has been used in the 1994 Disney animated feature film The Lion King.Lions are frequently depicted on coats of arms, like on the coat of arms of Finland, either as a device on shields or as supporters, but the lioness is used much less frequently. The heraldic lion is particularly common in British arms. It is traditionally depicted in a great variety of attitudes, although within French heraldry only lions rampant are considered to be lions; feline figures in any other position are instead referred to as leopards.

+The Siamese fireback (Lophura diardi), also known as Diard's fireback, is a fairly large, approximately 80 cm (31 in) long, pheasant. The male has a grey plumage with an extensive facial caruncle, crimson legs and feet, ornamental black crest feathers, reddish brown iris and long curved blackish tail. The female is a brown bird with blackish wing and tail feathers.
+
+The Siamese fireback is distributed to the lowland and evergreen forests of Cambodia, Laos, Thailand and Vietnam in Southeast Asia. This species is also designated as the national bird of Thailand. The female usually lays between four and eight rosy eggs.
+
+
+== Naming ==
+The scientific name commemorates the French naturalist Pierre-Médard Diard.
+This species of pheasant has a common name in Thai Kai Fah Phaya Lo (Thai: ไก่ฟ้าพญาลอ; Lord Lo's pheasant), according to Thai folk literature, Lilit Phra Lo where Phra Lo, the protagonist, is charmed by following the pheasant until he meets Phra Phuean and Phra Phaeng, the two sisters and later his lovers.

+The African bush elephant (Loxodonta africana) is one of two extant African elephant species and one of three extant elephant species. It is the largest living terrestrial animal, with bulls reaching a shoulder height of up to 3.96 m (13 ft 0 in) and a body mass of up to 10.4 t (11.5 short tons).
+It is distributed across 37 African countries and inhabits forests, grasslands and woodlands, wetlands and agricultural land. Since 2021, it has been listed as Endangered on the IUCN Red List. It is threatened foremost by habitat destruction, and in parts of its range also by poaching for meat and ivory. 
+It is a social mammal, travelling in herds composed of cows and their offspring. Adult bulls usually live alone or in small bachelor groups. It is a herbivore, feeding on grasses, creepers, herbs, leaves, and bark.
+The menstrual cycle lasts three to four months, and females are pregnant for 22 months, the longest gestation period of any mammal.
+
+
+== Taxonomy ==
+Elephas africanus was the scientific name proposed by Johann Friedrich Blumenbach in 1797.Loxodonte was proposed as generic name for African elephants by Frédéric Cuvier in 1825. This name refers to the lozenge-shaped enamel of the molar teeth, which differs significantly from the shape of the Asian elephant's molar enamel.In the 19th and 20th centuries, several zoological specimens were described by naturalists and curators of natural history museums from various parts of Africa, including:
+
+Elephas (Loxodonta) oxyotis and Elephas (Loxodonta) knochenhaueri by Paul Matschie in 1900. The first was a specimen from the upper Atbara River in northern Ethiopia, and the second a specimen from the Kilwa area in Tanzania.
+Elephas africanus toxotis, selousi, peeli,  cavendishi, orleansi and rothschildi by Richard Lydekker in 1907 who assumed that ear size is a distinguishing character for a race. These specimens were shot in South Africa, Mashonaland in Zimbabwe, Aberdare Mountains and Lake Turkana area in Kenya, Somaliland, and western Sudan, respectively.
+North African elephant (L. a. pharaohensis) by Paulus Edward Pieris Deraniyagala in 1948 was a specimen from Fayum in Egypt.Today, these names are all considered synonyms.
+
+
+=== Phylogeny ===
+
+A genetic study based on mitogenomic analysis revealed that the African and Asian elephant genetically diverged about 7.6 million years ago.Phylogenetic analysis of nuclear DNA of African bush and forest elephants, Asian elephant, woolly mammoth, and American mastodon revealed that the African bush elephant and the African forest elephant form a sister group that genetically diverged at least 1.9 million years ago. They are therefore considered distinct species. Gene flow between the two species, however, might have occurred after the split.
+
+
+== Characteristics ==
+
+
+=== Skin and ears ===
+
+The African bush elephant has grey skin with scanty hairs. Its large ears cover the whole shoulder, and can grow as large as 2 m × 1.5 m (6 ft 7 in × 4 ft 11 in).
+Large ears help to reduce body heat; flapping them creates air currents and exposes large blood vessels on the inner sides to increase heat loss during hot weather. The African bush elephant's ears are pointed and triangular shaped. Its occipital plane slopes forward. Its back is shaped markedly concave. Its sturdy tusks are curved out and point forward.
+
+
+=== Size ===
+
+The African bush elephant is the largest and heaviest land animal on Earth, with a maximum recorded shoulder height of an adult bull of 3.96 m (13.0 ft) and an estimated weight of up to 10.4 t (11.5 short tons). On average, males are about 3.20 m (10.5 ft) tall at the shoulder and weigh 6.0 t (6.6 short tons), while females are smaller at about 2.60 m (8 ft 6 in) tall at the shoulder and 3.0 t (3.3 short tons) in weight. Elephants attain their maximum stature when they complete the fusion of long-bone epiphyses, occurring in males around the age of 40 and females around the age of 25.
+
+
+=== Trunk ===
+The trunk is a prehensile elongation of the upper lip and nose. Short tactile hair grows on the trunk, which has two finger-like processes on the tip.
+This highly sensitive organ is innervated primarily by the trigeminal nerve, and is thought to be manipulated by about 40,000–60,000 muscles. Because of this muscular structure, the trunk is so strong that elephants can use it for lifting about 3% of their own body weight. They use it for smelling, touching, feeding, drinking, dusting, sound production, loading, defending, and attacking.
+Functional loss of the trunk due to floppy trunk syndrome sometimes forces elephants to carry their trunks over their tusks and walk into deep water to drink. A 2021 study found that African elephants can also use their trunks to suction up food and are capable of inhaling "at speeds exceeding 490 feet per second, or almost 30 times as fast as humans can sneeze."
+
+
+=== Tusks ===
+
+Both sexes have tusks, which erupt when they are 1–3 years old and grow throughout life. Tusks grow from deciduous teeth known as tushes that develop in the upper jaw and consist of a crown, root and pulpal cavity, which are completely formed soon after birth. Tushes reach a length of 5 cm (2.0 in).
+They are composed of dentin and coated with a thin layer of cementum. Their tips bear a conical layer of enamel that is usually worn off when the elephant is five years old.
+Tusks of bulls grow faster than tusks of cows. Mean weight of tusks at the age of 60 years is 109 kg (240 lb) in bulls and 17.7 kg (39 lb) in cows.
+The longest known tusk of an African bush elephant measured 3.51 m (11.5 ft) and weighed 117 kg (258 lb).
+
+
+=== Molars ===
+
+The dental formula of the African bush elephant is 1.0.3.30.0.3.3 × 2 = 26. It develops six molars in each jaw quadrant that erupt at different ages and differ in size. The first molars grow to a size of 2 cm (0.79 in) wide by 4 cm (1.6 in) long, are worn by the age of one year and lost by the age of about 2.5 years. The second molars start protruding at the age of about six months, and grow to a size of 4 cm (1.6 in) wide by 7 cm (2.8 in) long and are lost by the age of 6–7 years. The third molars protrude at the age of about one year, grow to a size of 5.2 cm (2.0 in) wide by 14 cm (5.5 in) long, and are lost by the age of 8–10 years. The fourth molars show by the age of 6–7 years, grow to a size of 6.8 cm (2.7 in) wide by 17.5 cm (6.9 in) long and are lost by the age of 22–23 years. The dental alveoli of the fifth molars are visible by the age of 10–11 years. They grow to a size of 8.5 cm (3.3 in) wide by 22 cm (8.7 in) long and are worn by the age of 45–48 years. The dental alveoli of the last molars are visible by the age of 26–28 years. They grow to a size of 9.4 cm (3.7 in) wide by 31 cm (12 in) long and are well worn by the age of 65 years.
+
+
+== Distribution and habitat ==
+The African bush elephant occurs in Sub-Saharan Africa including Uganda, Kenya, Tanzania, Botswana, Zimbabwe, Namibia, Zambia, and Angola. It moves between a variety of habitats, including subtropical and temperate forests, dry and seasonally flooded grasslands, woodlands, wetlands, and agricultural land from sea level to mountain slopes. In Mali and Namibia, it also inhabits desert and semi-desert areas.In Ethiopia, the African bush elephant has historically been recorded up to an elevation of 2,500 m (8,200 ft). By the late 1970s, the population had declined to a herd in the Dawa River valley and one close to the Kenyan border.
+
+
+== Behavior and ecology ==
+
+
+=== Social behavior ===
+
+The core of elephant society is the family unit, which comprises several adult cows, their daughters, and their prepubertal sons. Iain Douglas-Hamilton, who observed African bush elephants for 4.5 years in Lake Manyara National Park, coined the term 'kinship group' for two or more family units that have close ties. The family unit is led by a matriarch who at times also leads the kinship group. Groups cooperate in locating food and water, in self-defense, and in caring for offspring (termed allomothering). Group size varies seasonally and between locations. In Tsavo East and Tsavo West National Parks, groups are bigger in the rainy season and areas with open vegetation.
+Aerial surveys in the late 1960s to early 1970s revealed an average group size of 6.3 individuals in Uganda's Rwenzori National Park and 28.8 individuals in Chambura Game Reserve. In both sites, elephants aggregated during the wet season, whereas groups were smaller in the dry season.
+
+Young bulls gradually separate from the family unit when they are between 10 and 19 years old. They range alone for some time or form all-male groups. A 2020 study highlighted the importance of old bulls for the navigation and survival of herds and raised concerns over the removal of old bulls as "currently occur[ring] in both legal trophy hunting and illegal poaching".
+
+
+=== Temperature Regulation ===
+It was first hypothesized that African bush elephants sustain the intense savanna heat by performing heterothermy or matching their internal temperature with the environment. Instead, African bush elephants have curved skin that generates bending cracks which support thermoregulation by water retention. These bending cracks also contribute to an evaporative cooling process which causes elephants to maintain their body temperature regardless of air temperature via homeothermy. 
+
+
+=== Diet ===
+The African bush elephant is herbivorous. Its diet consists mainly of grasses, creepers, and herbs. Adults can consume up to 150 kg (330 lb) per day. During the dry season, the diet also includes leaves and bark. Tree bark in particular contains high levels of calcium. Elephants in captivity may consume leaves and fruit of cherimoya, papaya, banana, guava and leaves, stems and seeds of maize, sorghum and sugarcane.
+To supplement their diet with minerals, they congregate at mineral-rich water holes, termite mounds, and mineral licks. Salt licks visited by elephants in the Kalahari contain high concentrations of water-soluble sodium. Elephants drink 180–230 litres (50–60 US gal) of water daily, and seem to prefer sites where water and soil contain sodium. In Kruger National Park and on the shore of Lake Kariba, elephants were observed to ingest wood ash, which also contains sodium.
+
+
+=== Communication ===
+Africa bush elephants use their trunks for tactile communication. When greeting, a lower ranking individual will insert the tip of its trunk into its superior's mouth. Elephants will also stretch out their trunk toward an approaching individual they intend to greet. Mother elephants reassure their young with touches, embraces, and rubbings with the foot while slapping disciplines them. During courtship, a couple will caress and intertwine with their trunks while playing and fighting individuals wrestle with them.Elephant vocals are variations of rumbles, trumpets, squeals, and screams. Rumbles are mainly produced for long-distance communication and cover a broad range of frequencies which are mostly below what a human can hear. Infrasonic rumbles can travel vast distances and are important for attracting mates and scaring off rivals.
+
+At Amboseli National Park several different infrasonic calls have been identified:
+Greeting rumble – is emitted by adult female members of a family group that have united after having been separated for several hours.
+Contact call – soft, unmodulated sounds made by an individual that has been separated from the group.
+Contact answer – made in response to the contact call; starts out loud, but softens toward the end.
+"Let's go" rumble – a soft rumble emitted by the matriarch to signal to the other herd members that it is time to move to another spot.
+Musth rumble – distinctive, low-frequency pulsated rumble emitted by musth males (nicknamed the "motorcycle").
+Female chorus – a low-frequency, modulated chorus produced by several cows in response to a musth rumble.
+Postcopulatory call – made by an oestrous cow after mating.
+Mating pandemonium – calls of excitement made by a cow's family after she has mated.Growls are audible rumbles and happen during greetings. When in pain or fear, an elephant makes an open-mouthed growl known as a bellow while a drawn-out growl is a moan. Growling can escalate into a roaring when the elephant is issuing a threat. Trumpeting is made by blowing through the trunk and signals excitement, distress, or aggression. Juvenile elephants squeal in distress while screaming is made by adults for intimidation.
+
+
+=== Musth ===
+Bulls in musth experience swelling of the temporal glands and secretion of fluid, the musth fluid, which flows down their cheeks. They begin to dribble urine, initially as discrete drops and later in a regular stream. These manifestations of musth last from a few days to months, depending on the age and condition of the bull. When a bull has been urinating for a long time, the proximal part of the penis and the distal end of the sheath show a greenish coloration, termed the 'green penis syndrome' by Joyce Poole and Cynthia Moss. Males in musth become more aggressive. They guard and mate with females in estrus, who stay closer to bulls in musth than to non-musth bulls. Urinary testosterone increases during musth. Bulls begin to experience musth by the age of 24 years. Periods of musth are short and sporadic in young bulls up to 35 years old, lasting a few days to weeks. Older bulls are in musth for 2–5 months every year. Musth occurs mainly during and following the rainy season when females are in estrus. Bulls in musth often chase each other and are aggressive towards other bulls in musth. When old and high-ranking bulls in musth threaten and chase young musth bulls, either the latter leave the group or their musth ceases.
+
+Young bulls in musth killed about 50 white rhinoceros in Pilanesberg National Park between 1992 and 1997. This unusual behavior was attributed to their young age and inadequate socialisation; they were 17–25-year-old orphans from culled families that grew up without the guidance of dominant bulls. When six adult bulls were introduced into the park, the young bulls did not attack rhinos anymore, indicating older bulls suppress the musth and aggressiveness of younger bulls. Similar incidents were recorded in Hluhluwe-Umfolozi Park, where young bulls killed five black and 58 white rhinoceros between 1991 and 2001. After the introduction of ten bulls, each up to 45 years old, the number of rhinos killed by elephants decreased considerably.
+
+
+=== Reproduction ===
+
+Spermatogenesis starts when bulls are about 15 years old.
+Cows ovulate for the first time at the age of 11 years. They are in estrus for 2–6 days.
+In captivity, cows have an oestrous cycle lasting 14–15 weeks. Foetal gonads enlarge during the second half of pregnancy.African bush elephants mate during the rainy season. Bulls in musth cover long distances in search of cows and associate with large family units. They listen for the cows' loud, very low frequency calls and attract cows by calling and by leaving trails of strong-smelling urine. Cows search for bulls in musth, listen for their calls, and follow their urine trails.
+Bulls in musth are more successful at obtaining mating opportunities than those who are not. A cow may move away from bulls that attempt to test her estrous condition. If pursued by several bulls, she will run away. Once she chooses a mating partner, she will stay away from other bulls, which are threatened and chased away by the favoured bull. Competition between bulls overrides their choice sometimes.Gestation lasts 22 months. The interval between births was estimated at 3.9 to 4.7 years in Hwange National Park. Where hunting pressure on adult elephants was high in the 1970s, cows gave birth once in 2.9 to 3.8 years. Cows in Amboseli National Park gave birth once in 5 years on average.The birth of a calf was observed in Tsavo East National Park in October 1990. A group of 80 elephants including eight bulls had gathered in the morning in a 150 m (490 ft) radius around the birth site. A small group of calves and cows stood near the pregnant cow, rumbling and flapping their ears. One cow seemed to assist her. While she was in labour, fluid streamed from her temporal and ear canals. She remained standing while giving birth. The newborn calf struggled to its feet within 30 minutes and walked 20 minutes later. The mother expelled the placenta about 100 minutes after birth and covered it with soil immediately.Captive-born calves weigh between 100 and 120 kg (220 and 260 lb) at birth and gain about 0.5 kg (1.1 lb) weight per day.
+Cows lactate for about 4.8 years. 
+Calves exclusively suckle their mother's milk during the first three months. Thereafter, they start feeding independently and slowly increase the time spent feeding until they are two years old. During the first three years, male calves spend more time suckling and grow faster than female calves. After this period, cows reject male calves more frequently from nursing than female calves.The maximum lifespan of the African bush elephant is between 70 and 75 years. Its generation length is 25 years.
+
+
+=== Predators ===
+Adult elephants are considered invulnerable to predation. Calves, usually under two years, are sometimes preyed on by lions and spotted hyenas. Adult elephants often chase off predators, especially lions, by mobbing behavior. Juveniles are usually well defended by protective adults though serious drought makes them vulnerable to lion predation.In Botswana's Chobe National Park, lions attacked and fed on juvenile and subadult elephants during the drought when smaller prey species were scarce. Between 1993 and 1996, lions successfully attacked 74 elephants; 26 were older than nine, and one was a bull of over 15 years. Most were killed at night, and hunts occurred more often during waning moon nights than during bright moon nights. In the same park, lions killed eight elephants in October 2005 that were aged between 1 and 11 years, two of them older than 8 years. Successful hunts took place after dark when prides exceeded 27 lions and herds were smaller than 5 elephants.
+
+
+== Threats ==
+The African bush elephant is threatened primarily by habitat loss and fragmentation following conversion of natural habitat for livestock farming, plantations of non-timber crops, and building of urban and industrial areas. As a result, the human-elephant conflict has increased.
+
+
+=== Poaching ===
+Poachers target foremost elephant bulls for their tusks, which leads to a skewed sex ratio and affects the survival chances of a population. Access of poachers to unregulated black markets is facilitated by corruption and periods of civil war in some elephant range countries.During the 20th century, the African bush elephant population was decimated. Poaching of the elephant has dated back to the years 1970 and 1980, which were considered the largest killings in history. Unfortunately, the species is placed in harm's way due to the limited conservation areas provided in Africa. In most cases, the killings of the African bush elephant have occurred near the outskirts of the protected areas.Between 2003 and 2015, the illegal killing of 14,606 African bush elephants was reported by rangers across 29 range countries. Chad is a major transit country for smuggling of ivory in West Africa. This trend was curtailed by raising penalties for poaching and improving law enforcement.In June 2002, a container packed with more than 6.5 t (6.4 long tons; 7.2 short tons) ivory was confiscated in Singapore. It contained 42,120 hanko stamps and 532 tusks of African bush elephants that originated in Southern Africa, centered in Zambia and neighboring countries. Between 2005 and 2006, a total of 23.461 t (23.090 long tons; 25.861 short tons) ivory plus 91 unweighed tusks of African bush elephants were confiscated in 12 major consignments being shipped to Asia.When the international ivory trade reopened in 2006, the demand and price for ivory increased in Asia. The African bush elephant population in Chad's Zakouma National Park numbered 3,900 individuals in 2005. Within five years, more than 3,200 elephants were killed. The park did not have sufficient guards to combat poaching, and their weapons were outdated. Well-organized networks facilitated smuggling the ivory through Sudan.
+Poaching also increased in Kenya in those years.
+In Samburu National Reserve, 41 bulls were illegally killed between 2008 and 2012, equivalent to 31% of the reserve's elephant population.These killings were linked to confiscations of ivory and increased prices for ivory on the local black market.
+About 10,370 tusks were confiscated in Singapore, Hong Kong, Taiwan, Philippines, Thailand, Malaysia, Kenya and Uganda between 2007 and 2013. Genetic analysis of tusk samples showed that they originated from African bush elephants killed in Tanzania, Mozambique, Zambia, Kenya, and Uganda. Most of the ivory was smuggled through East African countries.In addition, to elephants being poached, their carcasses may be poisoned by the poachers to avoid detection by vultures, which help rangers detect poaching activity by circling dead animals. This poses a threat to those vultures or birds that scavenge the carcasses. On 20 June 2019, the carcasses of two tawny eagles and 537 endangered Old World vultures including 468 white-backed vultures, 17 white-headed vultures, 28 hooded vultures, 14 lappet-faced vultures and 10 Cape vultures found dead in northern Botswana were suspected to have died after eating the poisoned carcasses of three elephants.Intensive poaching leads to strong selection on tusk attributes; African elephants in areas with heavy poaching often have smaller tusks and a higher frequency of congenitally tuskless females, whereas congenital tusklessness is rarely if ever observed in males. A study in Mozambique's Gorongosa National Park revealed that poaching during the Mozambican Civil War lead to the increasing birth of tuskless females when the population recovered.
+
+
+=== Habitat changes ===
+Vast areas in Sub-Saharan Africa were transformed for agricultural use and the building of infrastructure. This disturbance leaves the elephants without a stable habitat and limits their ability to roam freely. Large corporations associated with commercial logging and mining have fragmented the land, giving poachers easy access to the African bush elephant. As human development grows, the human population faces the trouble of contact with the elephants more frequently, due to the species need for food and water. Farmers residing in nearby areas come into conflict with the African bush elephants rummaging through their crops. In many cases, they kill the elephants as soon as they disturb a village or forage upon its crops. Deaths caused by browsing on rubber vine, an invasive alien plant, have also been reported.
+
+
+=== Pathogens ===
+Observations at Etosha National Park indicate that African bush elephants die due to anthrax foremost in November at the end of the dry season. Anthrax spores spread through the intestinal tracts of vultures, jackals and hyaenas that feed on the carcasses. Anthrax killed over 100 elephants in Botswana in 2019.It is thought that wild bush elephants can contract fatal tuberculosis from humans. Infection of the vital organs by Citrobacter freundii bacteria caused the death of an otherwise healthy bush elephant after capture and translocation.From April to June 2020, over 400 bush elephants died in Botswana's Okavango Delta region after drinking from desiccating waterholes that were infested with cyanobacteria. Neurotoxins produced by the cyanobacteria caused calves and adult elephants to wander around confused, emaciated and in distress. The elephants collapsed when the toxin impaired their motor functions and their legs became paralysed. Poaching, intentional poisoning, and anthrax were excluded as potential causes.
+
+
+== Conservation ==
+
+Both African elephant species have been listed on Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora since 1989. In 1997, populations of Botswana, Namibia, and Zimbabwe were placed on CITES Appendix II, as were populations of South Africa in 2000. Community-based conservation programmes have been initiated in several range countries, which contributed to reducing human-elephant conflict and increasing local people's tolerance towards elephants.In 1986, the African Elephant Database was initiated to collate and update information on the distribution and status of elephant populations in Africa. The database includes results from aerial surveys, dung counts, interviews with local people, and data on poaching.Researchers discovered that playing back the recorded sounds of African bees is an effective method to drive elephants away from settlements.
+
+
+=== Status ===
+In 1996, IUCN Red List assessors for the African bush elephant considered the species Endangered. Since 2021, it has been assessed Endangered, after the global population was found to have decreased by more than 50% over 3 generations. About 70% of its range is located outside protected areas.In 2016, the global population was estimated at 415,428 ± 20,111 individuals distributed in a total area of 20,731,202 km2 (8,004,362 sq mi), of which 30% is protected. 42% of the total population lives in nine southern African countries comprising 293,447 ± 16,682 individuals; Africa's largest population lives in Botswana with 131,626 ± 12,508 individuals.
+
+
+=== In captivity ===
+The social behavior of elephants in captivity mimics that of those in the wild. Cows are kept with other cows, in groups, while bulls tend to be separated from their mothers at a young age and are kept apart. According to Schulte, in the 1990s, in North America, a few facilities allowed bull interaction. Elsewhere, bulls were only allowed to smell each other. Bulls and cows were allowed to interact for specific purposes such as breeding. In that event, cows were more often moved to the bull than the bull to the cow. Cows are more often kept in captivity because they are easier and less expensive to house.

+The Eurasian lynx (Lynx lynx) is a medium-sized wild cat widely distributed from Northern, Central and Eastern Europe to Central Asia and Siberia, the Tibetan Plateau and the Himalayas. It inhabits temperate and boreal forests up to an elevation of 5,500 m (18,000 ft). Despite its wide distribution, it is threatened by habitat loss and fragmentation, poaching and depletion of prey.
+
+
+== Taxonomy ==
+Felis lynx was the scientific name used in 1758 by Carl Linnaeus in his work Systema Naturae. In the 19th and 20th centuries, the following Eurasian lynx subspecies were proposed:
+The following were also proposed, but are not considered valid taxa:
+Altai lynx (L. l. wardi) Lydekker, 1904
+Baikal lynx (L. l. kozlovi) Fetisov, 1950
+Amur lynx (L. l. stroganovi) Heptner, 1969
+Sardinian lynx (L. l. sardiniae) Mola, 1908
+
+
+== Characteristics ==
+
+The Eurasian lynx has a relatively short, reddish or brown coat that is marked with black spots; their number and pattern are highly variable. The underparts, neck and chin are whitish. The fur is more brightly coloured with more numerous spots in animals living at the southern end of its range. In winter, it is much thicker and varies from silver-grey to greyish brown. Some animals have dark brown stripes on the forehead and back. It has powerful, relatively long legs, with large webbed and furred paws that act like snowshoes. It also has a short "bobbed" tail with an all-black tip, black tufts of hair on its ears, and a long grey-and-white ruff.It is the largest of the four lynx species, ranging in body length from 76–106 cm (30–42 in) in males; 73–99 cm (29–39 in) in females; and standing 55–75 cm (22–30 in) at the shoulder. The tail is 11–24.5 cm (4.3–9.6 in) long, constituting a total length of up to 130 cm (51 in) in the largest males. Weights of both sexes in Russia range from 12 to 32 kg (26 to 71 lb), but more than 30 kg (66 lb) is attained very rarely and is possibly exaggerated. A Eurasian lynx from the Altai Mountains weighed 35 kg (77 lb). Those inhabiting Fennoscandia and westwards are considerably smaller, with a range of just 7–26 kg (15–57 lb), though individuals in the Carpathian Mountains may rival those in the Altai in size.
+
+
+== Distribution and habitat ==
+
+The Eurasian lynx inhabits rugged country providing plenty of hideouts and stalking opportunities. Depending on the locality, this may include rocky-steppe, mixed forest-steppe, boreal forest, and montane forest ecosystems. In the more mountainous parts of its range, Eurasian lynx descends to the lowlands in winter, following prey species and avoiding deep snow. Despite its adaptations for moving in snow, it finds loose, deep snow difficult to deal with and cannot survive in areas with snow depths exceeding 100 cm (39 in). It tends to be less common where the grey wolf (Canis lupus) is abundant, and wolves have been reported to attack and even eat lynx.
+
+
+=== Europe ===
+The Eurasian lynx was once widespread throughout most of continental Europe. By the early 19th century, it was persecuted to local extinction in western and southern European lowlands, but survived only in mountainous areas and Scandinavian forests. By the 1950s, it had become extinct in most of Western and Central Europe, where only scattered and isolated populations exist today.
+
+
+==== Fennoscandia ====
+The Eurasian lynx was close to extinction in Scandinavia in the 1930s. Since the 1950s, the population slowly recovered and forms three subpopulations in northern, central and southern Scandinavia.
+In Norway, the Eurasian lynx was subjected to an official bounty between 1846 and 1980 and could be hunted without license. In 1994, a compensation scheme for livestock killed by lynx was introduced. By 1996, the lynx population was estimated to comprise 410 Individuals, decreased to less than 260 individuals in 2004 and increased since 2005 to about 452 mature individuals by 2008.In Sweden, the lynx population was estimated at about 1,400 individuals in 2006 and 1,250 in 2011. Hunting is controlled by government agencies.
+In Finland, about 2,200–2,300 individuals were present according to a 2009 estimate. The lynx population in Finland has been increasing every year since 1991, and is estimated to be nowadays larger than ever before. Limited hunting is permitted. In 2009 the Finnish Ministry of Agriculture and Forestry gave a permit for hunting of 340 lynx individuals.
+
+
+==== Western Europe ====
+In Great Britain, subfossil remains of Eurasian lynx have been dated to the early Middle Ages, though a breeding population in the Southern Uplands of Scotland was noted as late as 1760. Thus, it is possible that some Medieval and Early Modern references to "wild cats" and "cats of the mountain" actually refer to Eurasian lynx and not the Scottish wildcat as commonly assumed. It has been proposed to reintroduce the lynx to the Scottish Highlands and Kielder Forest in Northumberland.A large lynx that hunted deer and livestock, sometimes called "tiger" and "deer's wolf" (llobu/lobo cerval), was also reported in Green Spain until the 19th century. These accounts were traditionally regarded as references to Iberian lynx (Lynx pardinus), a smaller endemic species of the Iberian Peninsula. However, genetic testing of remains showed that the Eurasian and Iberian lynx coexisted into recent times in the Iberian Peninsula with little overlap, the Eurasian lynx being present in temperate broadleaf and mixed forests and the Iberian lynx in Mediterranean forests, woodlands, and scrub. The Eurasian lynx of Spain was a unique, extinct lineage more related to the Carpathian and Baltic subspecies. It was genetically impoverished already in pre-Roman times, possibly because of founder effect, which made it even more vulnerable to human persecution. The government of Asturias studied the feasibility of Eurasian lynx reintroduction in 2019. In the Catalonian Pyrenees, the last Eurasian lynx was killed in the 1930s, though unconfirmed sightings continued until the 1990s. The Síndic d'Aran planned a reintroduction in 2016 but canceled it due to the opposition of hunters and livestock farmers.In Germany, the Eurasian lynx was exterminated in 1850. It was reintroduced to the Bavarian Forest and the Harz in the 1990s; other areas were populated by lynxes migrating from France and the Czech Republic. In 2002, the first birth of wild lynx on German territory was announced, following a litter from a pair of lynx in the Harz National Park. Small populations exist also in Saxon Switzerland, Palatinate Forest, and Fichtelgebirge. Eurasian lynx also migrated to Austria, where they had also been exterminated. An episode of the PBS television series Nature featured the return of the lynx to Austria's Kalkalpen National Park after a 150-year absence. A higher proportion is killed by humans than by infectious diseases.The Eurasian lynx was exterminated in the French Alps in the early 20th century. Following reintroduction of lynx in the Swiss Jura Mountains in the 1970s, lynxes were recorded again in the French Alps and Jura from the late 1970s onwards. It recolonised the Italian Alps since the 1980s, also from reintroduced populations in Switzerland, Austria and Slovenia. By 2010, the Alpine lynx population comprised about 120–150 individuals ranging over 27,800 km2 (10,700 sq mi) in six sub-areas.In the Netherlands, lynxes have been sighted sporadically since 1985 in the country's southern part. Since 2020, the presence of lynxes has been confirmed by camera trapping in the Ardennes region in southern Belgium, proving the presence of the species following more than 25 years of unconfirmed sightings in the region.
+
+
+==== Central and Eastern Europe ====
+
+Carpathian Mountains: About 2,800 Eurasian lynx live in the mountain range, split between the Czech Republic, Poland, Romania, Slovakia, Ukraine and Hungary. It is the largest contiguous Eurasian lynx population west of the Russian border.
+Czech Republic: In Bohemia, the Eurasian lynx was exterminated in the 19th century (1830–1890) and in Moravia probably at the turn of the 20th century. After 1945, migration from Slovakia created a small and unstable population in Moravia. In the 1980s, almost 20 specimens were imported from Slovakia and reintroduced in the Šumava area. In early 2006, the population of lynx in the Czech Republic was estimated at 65–105 individuals. Hunting is prohibited, but the lynx is often threatened by poachers.
+Poland: In its Environment and Environmental Protection Section, the 2011 Central Statistical Office Report puts the number of Eurasian lynxes observed in the wild in Poland as of 2010 at approximately 285. There are two major populations of lynxes in Poland, one in the northeastern part of the country (most notably in the Białowieża Forest) and the other in the southeastern part in the Carpathian Mountains. Since the 1980s, lynxes have also been spotted in the region of Roztocze, Solska Forest, Polesie Lubelskie, and Karkonosze Mountains, though they still remain rare in those areas. A successfully reintroduced population of lynxes has also been living in the Kampinos National Park since the 1990s.
+Slovakia: the Eurasian lynx inhabits deciduous, coniferous and mixed forests at elevations of 180–1,592 m (591–5,223 ft), mostly in national parks and other protected areas; its presence has been positively confirmed in more than half of Slovak territory (2012). In terms of absolute numbers though in Štiavnica Mountains and Veľká Fatra National Park, surveys during 2011 to 2014 revealed that less than 30 individuals were present in these protected areas, with anthropic disturbances, poaching and insufficient counting methods used by forestry cited as the main causes of the unreliable population figures.
+Estonia: There are 900 individuals in Estonia according to a 2001 estimate. Although 180 lynx were legally hunted in Estonia in 2010, the country still has the highest known density of the species in Europe.
+Latvia: According to a 2005 estimate, about 700 animals inhabit areas in Courland and Vidzeme.
+Lithuania: The population is estimated at 80–100 animals.
+Belarus: the most recent data from the national parks, reserves, and hunting grounds demonstrate the number of lynxes in Belarus to be in the range of 550 to 600 animals.
+Russia: As of 2013, the Russian lynx population is estimated as comprising 22,510 individuals and is considered abundant and stable in some regions.
+Balkan peninsula: The Balkan lynx subspecies is found in Croatia, Montenegro, Albania, Kosovo, North Macedonia, Bulgaria and possibly Greece. They can be found in remote mountainous regions of the Balkans, with the largest numbers in remote hills of western North Macedonia, eastern Albania and northern Albania. The Balkan lynx is considered a national symbol of North Macedonia, and it is depicted on the reverse of the North Macedonian 5 denars coin, issued in 1993. The name of Lynkestis, a Macedonian tribe, is translated as "Land of the Lynx". It has been on the brink of extinction for nearly 100 years. Numbers are estimated to be around 100, and the decline is due to illegal poaching.
+Dinaric Alps and Julian Alps: Slovenia, Croatia, and Bosnia and Herzegovina are home to approx. 130–200 lynx. The Eurasian lynx had been considered extinct in these countries since the beginning of the 20th century. However, a successful reintroduction project was carried out in Slovenia in 1973, when three female and three male lynx from Slovakia were released in the Kočevski Rog forest. Today, lynx are present in the Dinaric forests of the south and southeastern part of Slovenia and in the Croatian regions of Gorski kotar and Velebit, spanning the Dinaric Alps and over the Dinara Mountains into western Bosnia and Herzegovina. The lynx has been also spotted in the Julian Alps and elsewhere in western Slovenia, but the A1 motorway presents a significant hindrance to the development of the population there. Croatia's Plitvice Lakes National Park is home to several pairs of the lynx. In the three countries, the Eurasian lynx is listed as an endangered species and protected by law. Realistic population estimates are 40 lynx in Slovenia, 40–60 in Croatia, and more than 50 in Bosnia and Herzegovina. The Croatian massif Risnjak in Risnjak National Park probably got its name from the Croatian word for the lynx, ris.
+Hungary: The population is estimated at 10-12 animals, in the northern mountain ranges of the country close to Slovakia.
+Romania: over 2,000 Eurasian lynx live in Romania, including most of the Carpathian population. However, some experts consider these official population numbers to be overestimated. Limited hunting is permitted but the population is stable.
+Bulgaria: the animal was declared extinct in Bulgaria in 1985, but sightings continued well into the 1990s. In 2006 an audio recording of a lynx mating call was made in the Strandzha mountain range in the southeast. Two years later an ear-marked individual was accidentally shot near Belogradchik in the northwest, and a few months later a mounted trap camera caught a glimpse of another individual. Further camera records followed in Osogovo and Strandzha, confirming that the species has returned to the country. A thorough examination on the subject is yet to be made available.
+Ukraine: The Eurasian lynx is native to forested areas of the country. Before the 19th century it was common also in the forest steppe zone. Nowadays, the most significant populations remain in the Carpathian mountains and across the forests of Polesia. The population is estimated as 80–90 animals for the Polesia region and 350–400 for the forests of the Carpathians.
+
+
+=== Asia ===
+
+
+==== Anatolia and Caucasus ====
+In the Anatolian part of Turkey, the Eurasian lynx is present in the Lesser Caucasus, Kaçkar Mountains and Artvin Province. In Ciglikara Nature Reserve located in the Taurus Mountains, 15 individuals were identified. More than 50 individuals were identified and monitored at a forest-steppe mixed ecosystem in northwestern Anatolia by camera traps, genetic material and radiotelemetry between 2009 and 2019. In Kars Province, a breeding population occurs in Sarıkamış-Allahuekber Mountains National Park.
+The Eurasian lynx and grey wolf can occur sympatrically, as they occupy different trophic niches.
+
+
+==== Central Asia ====
+In Central Asia, it is native to Kazakhstan, Uzbekistan, Turkmenistan, Kyrgyzstan, Tajikistan, Afghanistan and the Chinese provinces of Xinjiang, Gansu, Qinghai, Sichuan, Shaanxi, and to the northern slopes of Iran's Alborz Mountains and Mongolia.In northern Pakistan, the Eurasian lynx was recorded at elevations of 1,067–5,000 m (3,501–16,404 ft) in Chitral District.
+In India: Ladakh, Himachal Pradesh and most other Himalayan states.
+In Nepal, a Eurasian lynx was sighted in the western Dhaulagiri massif in 1975. It is also present above elevations of 3,800 m (12,500 ft) in Humla, Mustang and Dolpa Districts.
+
+
+==== East Asia ====
+Fossils of the Eurasian or a closely related Lynx species from the Late Pleistocene era and onward were excavated at various locations in the Japanese archipelago. Since no archaeological evidence after the Yayoi period was found, it was probably eradicated during the Jōmon period.
+
+
+== Behaviour and ecology ==
+
+Although they may hunt during the day when food is scarce, the Eurasian lynx is mainly nocturnal or crepuscular, and spends the day sleeping in dense thickets or other places of concealment. It lives solitarily as an adult. The hunting area of Eurasian lynx can be anything from 20 to 450 km2 (7.7 to 173.7 sq mi), depending on the local availability of prey. Males tend to hunt over much larger areas than females, which tend to occupy exclusive, rather than overlapping, hunting ranges. The Eurasian lynx can travel up to 20 km (12 mi) during one night, although about half this distance is more typical. They patrol regularly throughout all parts of their hunting range, using scent marks to indicate their presence to other individuals. As with other cats, its scent marks may consist of faeces, urine, or scrape marks, with the former often being left in prominent locations along the boundary of the hunting territory. Eurasian lynx makes a range of vocalizations, but is generally silent outside of the breeding season. They have been observed to mew, hiss, growl, and purr, and, like domestic cats, will "chatter" at prey that is just out of reach. Mating calls are much louder, consisting of deep growls in the male, and loud "meow-like" sounds in the female. Eurasian lynx are secretive, and because the sounds they make are very quiet and seldom heard, their presence in an area may go unnoticed for years. Remnants of prey or tracks on snow are usually observed long before the animal is seen.
+
+
+=== Diet and hunting ===
+
+
+==== Diet in Europe ====
+Eurasian lynx in Europe prey largely on small to fairly large sized mammals and birds. Among the recorded prey items for the species are hares, rabbits, marmots, squirrels, dormice, other rodents, mustelids (such as martens), grouse, red foxes, wild boar, chamois, young moose, roe deer, red deer, reindeer and other ungulates. In keeping with its larger size, the Eurasian lynx is the only lynx species to preferentially take ungulates (the Iberian lynx and Canada lynx being specialists on lagomorph prey, while the bobcat is an opportunistic generalist). Although taking on larger prey presents a risk to the animal, the bounty provided by killing them can outweigh the risks. The Eurasian lynx thus prefers fairly large ungulate prey, especially during winter, when small prey is less abundant. Where common, roe deer appear to be the preferred prey species for the lynx.In Estonia, a typical adult lynx kills about 60 roe deer a year; in the years when the roe deer population plummets, the lynx switch to beavers, hares, foxes, raccoon dogs, and birds. Even where roe deer are quite uncommon, the deer are still quantitatively the favored prey species, though in summer smaller prey and occasional domestic sheep are eaten more regularly. In parts of Finland, introduced white-tailed deer are eaten regularly. In some areas in Poland and Austria, red deer is the preferred prey, and in Switzerland, chamois is locally favored. Eurasian lynx also feeds on carrion when available. Adult lynx require 1.1 to 2 kilograms (2.4 to 4.4 lb) of meat per day, and may take several days to fully consume some of their larger prey.
+
+
+==== Diet in Asia ====
+In the Mediterranean mixed forest-steppe and subalpine ecosystems of Anatolia the main and most preferred prey of the Eurasian lynx is European hare, forming 79% to 99% of prey biomass eaten. Although the lynx is in sympatry with wild ungulates, such as wild goat, chamois, red deer and wild boar in these ecosystems, ungulate biomass in lynx diet does not exceed 10%. In ten other study sites in the Black Sea region of northern Anatolia where roe deer can occur in high densities, lynx occurrence is positively correlated with European hare occurrence rather than roe deer. Lynx in Anatolia also has physiological requirements and morphological adjustments similar to other lagomorph specialists, with a daily prey intake of about 900 g (32 oz). It is therefore classified as lagomorph specialist. Diet studies in central and northern Asia also indicate a diet mainly composed of lagomorphs and ungulate prey contributes in low amounts to lynx diet.
+Eurasian lynx scat found in Dolpa District in the Nepal Himalayas contained remains of woolly hare (Lepus oiostolus), pika (Ochotona sp.), mountain voles (Alticola sp.), Himalayan marmot (Marmota himalayana) and domestic goat (Capra hircus).
+
+
+==== Hunting ====
+The main method of hunting is stalking, sneaking and jumping on prey, although they are also ambush predators when conditions are suitable. In winter certain snow conditions make this harder and the animal may be forced to switch to larger prey in Europe. Eurasian lynx hunt using both vision and hearing, and often climb onto high rocks or fallen trees to scan the surrounding area. A very powerful predator, these lynxes have successfully killed adult deer weighing to at least 150 kg (330 lb).
+
+
+=== Reproduction ===
+
+The mating season of the Eurasian lynx lasts from January to April. The female typically comes into oestrus only once during this period, lasting from four to seven days. If the first litter is lost, a second period of oestrus is common. It does not appear to be able to control its reproductive behaviour based on prey availability. Gestation lasts from 67 to 74 days. Pregnant females construct dens in secluded locations, often protected by overhanging branches or tree roots. The den is lined with feathers, deer hair, and dry grass to provide bedding for the young. At birth, Eurasian lynx kittens weigh 240 to 430 g (8.5 to 15.2 oz) and open their eyes after ten to twelve days. They initially have plain, greyish-brown fur, attaining the full adult colouration around eleven weeks of age. They begin to take solid food at six to seven weeks, when they begin to leave the den, but are not fully weaned for five or six months. The den is abandoned two to three months after the kittens are born, but the young typically remain with their mother until they are around ten months of age. Eurasian lynx reach sexual maturity at two or three years, and have lived for twenty one years in captivity.Females usually have two kittens; litters with more than three kittens are rare.
+
+
+== Predators and interspecies predatory relationships ==
+The primary predators of the lynx are the gray wolf and the wolverine. In Russian forests, gray wolves kill and eat lynx that fail to escape into trees, as evidenced by examination of wolf and lynx trackways in the Central Forest Nature Reserve, and of lynx hair and bones found in wolf stomach contents in the Belovezh Forest. The lynx saves itself from its enemies by quickly climbing a tree or a cliff; it usually lives near a 'stronghold' place and eats its food in a high tree or cliff. Lynx populations decrease when wolves appear in a region such as observed in the Pritelsk region of the Altai Mountains, and lynx are likely to take smaller prey where wolves are active. In eastern Slovakia, after an increase of wolves after World War II, lynx  were observed to move out.However, there is also a reported instance of a male lynx having expelled an adult and apparently healthy male wolf in Belarus in a fight. After the incident the wolf vanished from the record, suggesting that it might have succumbed to the wounds sustained during the fight. Moreover, recent population dynamics and a high mortality rate among wolf cubs in the Naliboki forest might be connected to an increasing lynx population. All in all this suggests that at least locally lynx may dominate wolves, since no signs for predation of wolves on lynx was found. In the Pechora-Ilych Nature Reserve in Russia wolverine predation and consumption of a lynx has been documented, and in the Altai Mountains, the lynx avoids wolverines.The gray wolf, wolverine, as well as the red fox and the eagle owl, are also competitors of the Eurasian lynx for food in the taiga regions of Russia. In years of low hare populations, the competition becomes especially strong, and the lynx is at a disadvantage because its competitors are able to secure other prey more efficiently. This competition may be especially severe in the northern parts of the lynx's range where lynx populations are vastly outnumbered by red fox and even by wolverines. The presence of other large carnivores is one factor limiting their population.In two ecosystems of Anatolia, cannibalism was common and lynx were found to form 5% to 8% of prey biomass in diet. Claws and bones analysed showed that sub-adult lynx were the victims of cannibalism during the mating and spring seasons. Lynx were not found in the sympatrically occurring wolves' diet, however, lynxes themselves were the predator of red foxes, martens, domestic cats and dogs, and golden jackal remains have been found in lynx fecal samples. Sometimes, Siberian tigers have also preyed on lynxes, as evidenced by examination of tiger stomach contents.
+In Sweden, out of 33 deaths of lynx of a population being observed, one was probably killed by a wolverine. Lynx compete for food with the predators described above, and also with the red fox, eagle owls, golden eagles, wild boar (which scavenge from lynx kills), and in the southern part of its range, the snow leopard and leopard as well. Brown bears, although not (so far as is known) a predator of Eurasian lynx, are in some areas a semi-habitual usurpers of ungulate kills by lynxes, not infrequently before the cat has had a chance to consume its kill itself.
+
+
+== Conservation ==
+
+The Eurasian lynx is included on CITES Appendix II and listed as a protected species in the Berne Convention on the Conservation of European Wildlife and Natural Habitats, Appendix III. Hunting lynx is illegal in many range countries, with the exception of Estonia, Latvia, Russia, Armenia and Iraq. Since 2005, the Norwegian government sets national population goals, while a committee of representatives from county assemblies decide on hunting quotas.

+The Eurasian lynx (Lynx lynx) is a medium-sized wild cat widely distributed from Northern, Central and Eastern Europe to Central Asia and Siberia, the Tibetan Plateau and the Himalayas. It inhabits temperate and boreal forests up to an elevation of 5,500 m (18,000 ft). Despite its wide distribution, it is threatened by habitat loss and fragmentation, poaching and depletion of prey.
+
+
+== Taxonomy ==
+Felis lynx was the scientific name used in 1758 by Carl Linnaeus in his work Systema Naturae. In the 19th and 20th centuries, the following Eurasian lynx subspecies were proposed:
+The following were also proposed, but are not considered valid taxa:
+Altai lynx (L. l. wardi) Lydekker, 1904
+Baikal lynx (L. l. kozlovi) Fetisov, 1950
+Amur lynx (L. l. stroganovi) Heptner, 1969
+Sardinian lynx (L. l. sardiniae) Mola, 1908
+
+
+== Characteristics ==
+
+The Eurasian lynx has a relatively short, reddish or brown coat that is marked with black spots; their number and pattern are highly variable. The underparts, neck and chin are whitish. The fur is more brightly coloured with more numerous spots in animals living at the southern end of its range. In winter, it is much thicker and varies from silver-grey to greyish brown. Some animals have dark brown stripes on the forehead and back. It has powerful, relatively long legs, with large webbed and furred paws that act like snowshoes. It also has a short "bobbed" tail with an all-black tip, black tufts of hair on its ears, and a long grey-and-white ruff.It is the largest of the four lynx species, ranging in body length from 76–106 cm (30–42 in) in males; 73–99 cm (29–39 in) in females; and standing 55–75 cm (22–30 in) at the shoulder. The tail is 11–24.5 cm (4.3–9.6 in) long, constituting a total length of up to 130 cm (51 in) in the largest males. Weights of both sexes in Russia range from 12 to 32 kg (26 to 71 lb), but more than 30 kg (66 lb) is attained very rarely and is possibly exaggerated. A Eurasian lynx from the Altai Mountains weighed 35 kg (77 lb). Those inhabiting Fennoscandia and westwards are considerably smaller, with a range of just 7–26 kg (15–57 lb), though individuals in the Carpathian Mountains may rival those in the Altai in size.
+
+
+== Distribution and habitat ==
+
+The Eurasian lynx inhabits rugged country providing plenty of hideouts and stalking opportunities. Depending on the locality, this may include rocky-steppe, mixed forest-steppe, boreal forest, and montane forest ecosystems. In the more mountainous parts of its range, Eurasian lynx descends to the lowlands in winter, following prey species and avoiding deep snow. Despite its adaptations for moving in snow, it finds loose, deep snow difficult to deal with and cannot survive in areas with snow depths exceeding 100 cm (39 in). It tends to be less common where the grey wolf (Canis lupus) is abundant, and wolves have been reported to attack and even eat lynx.
+
+
+=== Europe ===
+The Eurasian lynx was once widespread throughout most of continental Europe. By the early 19th century, it was persecuted to local extinction in western and southern European lowlands, but survived only in mountainous areas and Scandinavian forests. By the 1950s, it had become extinct in most of Western and Central Europe, where only scattered and isolated populations exist today.
+
+
+==== Fennoscandia ====
+The Eurasian lynx was close to extinction in Scandinavia in the 1930s. Since the 1950s, the population slowly recovered and forms three subpopulations in northern, central and southern Scandinavia.
+In Norway, the Eurasian lynx was subjected to an official bounty between 1846 and 1980 and could be hunted without license. In 1994, a compensation scheme for livestock killed by lynx was introduced. By 1996, the lynx population was estimated to comprise 410 Individuals, decreased to less than 260 individuals in 2004 and increased since 2005 to about 452 mature individuals by 2008.In Sweden, the lynx population was estimated at about 1,400 individuals in 2006 and 1,250 in 2011. Hunting is controlled by government agencies.
+In Finland, about 2,200–2,300 individuals were present according to a 2009 estimate. The lynx population in Finland has been increasing every year since 1991, and is estimated to be nowadays larger than ever before. Limited hunting is permitted. In 2009 the Finnish Ministry of Agriculture and Forestry gave a permit for hunting of 340 lynx individuals.
+
+
+==== Western Europe ====
+In Great Britain, subfossil remains of Eurasian lynx have been dated to the early Middle Ages, though a breeding population in the Southern Uplands of Scotland was noted as late as 1760. Thus, it is possible that some Medieval and Early Modern references to "wild cats" and "cats of the mountain" actually refer to Eurasian lynx and not the Scottish wildcat as commonly assumed. It has been proposed to reintroduce the lynx to the Scottish Highlands and Kielder Forest in Northumberland.A large lynx that hunted deer and livestock, sometimes called "tiger" and "deer's wolf" (llobu/lobo cerval), was also reported in Green Spain until the 19th century. These accounts were traditionally regarded as references to Iberian lynx (Lynx pardinus), a smaller endemic species of the Iberian Peninsula. However, genetic testing of remains showed that the Eurasian and Iberian lynx coexisted into recent times in the Iberian Peninsula with little overlap, the Eurasian lynx being present in temperate broadleaf and mixed forests and the Iberian lynx in Mediterranean forests, woodlands, and scrub. The Eurasian lynx of Spain was a unique, extinct lineage more related to the Carpathian and Baltic subspecies. It was genetically impoverished already in pre-Roman times, possibly because of founder effect, which made it even more vulnerable to human persecution. The government of Asturias studied the feasibility of Eurasian lynx reintroduction in 2019. In the Catalonian Pyrenees, the last Eurasian lynx was killed in the 1930s, though unconfirmed sightings continued until the 1990s. The Síndic d'Aran planned a reintroduction in 2016 but canceled it due to the opposition of hunters and livestock farmers.In Germany, the Eurasian lynx was exterminated in 1850. It was reintroduced to the Bavarian Forest and the Harz in the 1990s; other areas were populated by lynxes migrating from France and the Czech Republic. In 2002, the first birth of wild lynx on German territory was announced, following a litter from a pair of lynx in the Harz National Park. Small populations exist also in Saxon Switzerland, Palatinate Forest, and Fichtelgebirge. Eurasian lynx also migrated to Austria, where they had also been exterminated. An episode of the PBS television series Nature featured the return of the lynx to Austria's Kalkalpen National Park after a 150-year absence. A higher proportion is killed by humans than by infectious diseases.The Eurasian lynx was exterminated in the French Alps in the early 20th century. Following reintroduction of lynx in the Swiss Jura Mountains in the 1970s, lynxes were recorded again in the French Alps and Jura from the late 1970s onwards. It recolonised the Italian Alps since the 1980s, also from reintroduced populations in Switzerland, Austria and Slovenia. By 2010, the Alpine lynx population comprised about 120–150 individuals ranging over 27,800 km2 (10,700 sq mi) in six sub-areas.In the Netherlands, lynxes have been sighted sporadically since 1985 in the country's southern part. Since 2020, the presence of lynxes has been confirmed by camera trapping in the Ardennes region in southern Belgium, proving the presence of the species following more than 25 years of unconfirmed sightings in the region.
+
+
+==== Central and Eastern Europe ====
+
+Carpathian Mountains: About 2,800 Eurasian lynx live in the mountain range, split between the Czech Republic, Poland, Romania, Slovakia, Ukraine and Hungary. It is the largest contiguous Eurasian lynx population west of the Russian border.
+Czech Republic: In Bohemia, the Eurasian lynx was exterminated in the 19th century (1830–1890) and in Moravia probably at the turn of the 20th century. After 1945, migration from Slovakia created a small and unstable population in Moravia. In the 1980s, almost 20 specimens were imported from Slovakia and reintroduced in the Šumava area. In early 2006, the population of lynx in the Czech Republic was estimated at 65–105 individuals. Hunting is prohibited, but the lynx is often threatened by poachers.
+Poland: In its Environment and Environmental Protection Section, the 2011 Central Statistical Office Report puts the number of Eurasian lynxes observed in the wild in Poland as of 2010 at approximately 285. There are two major populations of lynxes in Poland, one in the northeastern part of the country (most notably in the Białowieża Forest) and the other in the southeastern part in the Carpathian Mountains. Since the 1980s, lynxes have also been spotted in the region of Roztocze, Solska Forest, Polesie Lubelskie, and Karkonosze Mountains, though they still remain rare in those areas. A successfully reintroduced population of lynxes has also been living in the Kampinos National Park since the 1990s.
+Slovakia: the Eurasian lynx inhabits deciduous, coniferous and mixed forests at elevations of 180–1,592 m (591–5,223 ft), mostly in national parks and other protected areas; its presence has been positively confirmed in more than half of Slovak territory (2012). In terms of absolute numbers though in Štiavnica Mountains and Veľká Fatra National Park, surveys during 2011 to 2014 revealed that less than 30 individuals were present in these protected areas, with anthropic disturbances, poaching and insufficient counting methods used by forestry cited as the main causes of the unreliable population figures.
+Estonia: There are 900 individuals in Estonia according to a 2001 estimate. Although 180 lynx were legally hunted in Estonia in 2010, the country still has the highest known density of the species in Europe.
+Latvia: According to a 2005 estimate, about 700 animals inhabit areas in Courland and Vidzeme.
+Lithuania: The population is estimated at 80–100 animals.
+Belarus: the most recent data from the national parks, reserves, and hunting grounds demonstrate the number of lynxes in Belarus to be in the range of 550 to 600 animals.
+Russia: As of 2013, the Russian lynx population is estimated as comprising 22,510 individuals and is considered abundant and stable in some regions.
+Balkan peninsula: The Balkan lynx subspecies is found in Croatia, Montenegro, Albania, Kosovo, North Macedonia, Bulgaria and possibly Greece. They can be found in remote mountainous regions of the Balkans, with the largest numbers in remote hills of western North Macedonia, eastern Albania and northern Albania. The Balkan lynx is considered a national symbol of North Macedonia, and it is depicted on the reverse of the North Macedonian 5 denars coin, issued in 1993. The name of Lynkestis, a Macedonian tribe, is translated as "Land of the Lynx". It has been on the brink of extinction for nearly 100 years. Numbers are estimated to be around 100, and the decline is due to illegal poaching.
+Dinaric Alps and Julian Alps: Slovenia, Croatia, and Bosnia and Herzegovina are home to approx. 130–200 lynx. The Eurasian lynx had been considered extinct in these countries since the beginning of the 20th century. However, a successful reintroduction project was carried out in Slovenia in 1973, when three female and three male lynx from Slovakia were released in the Kočevski Rog forest. Today, lynx are present in the Dinaric forests of the south and southeastern part of Slovenia and in the Croatian regions of Gorski kotar and Velebit, spanning the Dinaric Alps and over the Dinara Mountains into western Bosnia and Herzegovina. The lynx has been also spotted in the Julian Alps and elsewhere in western Slovenia, but the A1 motorway presents a significant hindrance to the development of the population there. Croatia's Plitvice Lakes National Park is home to several pairs of the lynx. In the three countries, the Eurasian lynx is listed as an endangered species and protected by law. Realistic population estimates are 40 lynx in Slovenia, 40–60 in Croatia, and more than 50 in Bosnia and Herzegovina. The Croatian massif Risnjak in Risnjak National Park probably got its name from the Croatian word for the lynx, ris.
+Hungary: The population is estimated at 10-12 animals, in the northern mountain ranges of the country close to Slovakia.
+Romania: over 2,000 Eurasian lynx live in Romania, including most of the Carpathian population. However, some experts consider these official population numbers to be overestimated. Limited hunting is permitted but the population is stable.
+Bulgaria: the animal was declared extinct in Bulgaria in 1985, but sightings continued well into the 1990s. In 2006 an audio recording of a lynx mating call was made in the Strandzha mountain range in the southeast. Two years later an ear-marked individual was accidentally shot near Belogradchik in the northwest, and a few months later a mounted trap camera caught a glimpse of another individual. Further camera records followed in Osogovo and Strandzha, confirming that the species has returned to the country. A thorough examination on the subject is yet to be made available.
+Ukraine: The Eurasian lynx is native to forested areas of the country. Before the 19th century it was common also in the forest steppe zone. Nowadays, the most significant populations remain in the Carpathian mountains and across the forests of Polesia. The population is estimated as 80–90 animals for the Polesia region and 350–400 for the forests of the Carpathians.
+
+
+=== Asia ===
+
+
+==== Anatolia and Caucasus ====
+In the Anatolian part of Turkey, the Eurasian lynx is present in the Lesser Caucasus, Kaçkar Mountains and Artvin Province. In Ciglikara Nature Reserve located in the Taurus Mountains, 15 individuals were identified. More than 50 individuals were identified and monitored at a forest-steppe mixed ecosystem in northwestern Anatolia by camera traps, genetic material and radiotelemetry between 2009 and 2019. In Kars Province, a breeding population occurs in Sarıkamış-Allahuekber Mountains National Park.
+The Eurasian lynx and grey wolf can occur sympatrically, as they occupy different trophic niches.
+
+
+==== Central Asia ====
+In Central Asia, it is native to Kazakhstan, Uzbekistan, Turkmenistan, Kyrgyzstan, Tajikistan, Afghanistan and the Chinese provinces of Xinjiang, Gansu, Qinghai, Sichuan, Shaanxi, and to the northern slopes of Iran's Alborz Mountains and Mongolia.In northern Pakistan, the Eurasian lynx was recorded at elevations of 1,067–5,000 m (3,501–16,404 ft) in Chitral District.
+In India: Ladakh, Himachal Pradesh and most other Himalayan states.
+In Nepal, a Eurasian lynx was sighted in the western Dhaulagiri massif in 1975. It is also present above elevations of 3,800 m (12,500 ft) in Humla, Mustang and Dolpa Districts.
+
+
+==== East Asia ====
+Fossils of the Eurasian or a closely related Lynx species from the Late Pleistocene era and onward were excavated at various locations in the Japanese archipelago. Since no archaeological evidence after the Yayoi period was found, it was probably eradicated during the Jōmon period.
+
+
+== Behaviour and ecology ==
+
+Although they may hunt during the day when food is scarce, the Eurasian lynx is mainly nocturnal or crepuscular, and spends the day sleeping in dense thickets or other places of concealment. It lives solitarily as an adult. The hunting area of Eurasian lynx can be anything from 20 to 450 km2 (7.7 to 173.7 sq mi), depending on the local availability of prey. Males tend to hunt over much larger areas than females, which tend to occupy exclusive, rather than overlapping, hunting ranges. The Eurasian lynx can travel up to 20 km (12 mi) during one night, although about half this distance is more typical. They patrol regularly throughout all parts of their hunting range, using scent marks to indicate their presence to other individuals. As with other cats, its scent marks may consist of faeces, urine, or scrape marks, with the former often being left in prominent locations along the boundary of the hunting territory. Eurasian lynx makes a range of vocalizations, but is generally silent outside of the breeding season. They have been observed to mew, hiss, growl, and purr, and, like domestic cats, will "chatter" at prey that is just out of reach. Mating calls are much louder, consisting of deep growls in the male, and loud "meow-like" sounds in the female. Eurasian lynx are secretive, and because the sounds they make are very quiet and seldom heard, their presence in an area may go unnoticed for years. Remnants of prey or tracks on snow are usually observed long before the animal is seen.
+
+
+=== Diet and hunting ===
+
+
+==== Diet in Europe ====
+Eurasian lynx in Europe prey largely on small to fairly large sized mammals and birds. Among the recorded prey items for the species are hares, rabbits, marmots, squirrels, dormice, other rodents, mustelids (such as martens), grouse, red foxes, wild boar, chamois, young moose, roe deer, red deer, reindeer and other ungulates. In keeping with its larger size, the Eurasian lynx is the only lynx species to preferentially take ungulates (the Iberian lynx and Canada lynx being specialists on lagomorph prey, while the bobcat is an opportunistic generalist). Although taking on larger prey presents a risk to the animal, the bounty provided by killing them can outweigh the risks. The Eurasian lynx thus prefers fairly large ungulate prey, especially during winter, when small prey is less abundant. Where common, roe deer appear to be the preferred prey species for the lynx.In Estonia, a typical adult lynx kills about 60 roe deer a year; in the years when the roe deer population plummets, the lynx switch to beavers, hares, foxes, raccoon dogs, and birds. Even where roe deer are quite uncommon, the deer are still quantitatively the favored prey species, though in summer smaller prey and occasional domestic sheep are eaten more regularly. In parts of Finland, introduced white-tailed deer are eaten regularly. In some areas in Poland and Austria, red deer is the preferred prey, and in Switzerland, chamois is locally favored. Eurasian lynx also feeds on carrion when available. Adult lynx require 1.1 to 2 kilograms (2.4 to 4.4 lb) of meat per day, and may take several days to fully consume some of their larger prey.
+
+
+==== Diet in Asia ====
+In the Mediterranean mixed forest-steppe and subalpine ecosystems of Anatolia the main and most preferred prey of the Eurasian lynx is European hare, forming 79% to 99% of prey biomass eaten. Although the lynx is in sympatry with wild ungulates, such as wild goat, chamois, red deer and wild boar in these ecosystems, ungulate biomass in lynx diet does not exceed 10%. In ten other study sites in the Black Sea region of northern Anatolia where roe deer can occur in high densities, lynx occurrence is positively correlated with European hare occurrence rather than roe deer. Lynx in Anatolia also has physiological requirements and morphological adjustments similar to other lagomorph specialists, with a daily prey intake of about 900 g (32 oz). It is therefore classified as lagomorph specialist. Diet studies in central and northern Asia also indicate a diet mainly composed of lagomorphs and ungulate prey contributes in low amounts to lynx diet.
+Eurasian lynx scat found in Dolpa District in the Nepal Himalayas contained remains of woolly hare (Lepus oiostolus), pika (Ochotona sp.), mountain voles (Alticola sp.), Himalayan marmot (Marmota himalayana) and domestic goat (Capra hircus).
+
+
+==== Hunting ====
+The main method of hunting is stalking, sneaking and jumping on prey, although they are also ambush predators when conditions are suitable. In winter certain snow conditions make this harder and the animal may be forced to switch to larger prey in Europe. Eurasian lynx hunt using both vision and hearing, and often climb onto high rocks or fallen trees to scan the surrounding area. A very powerful predator, these lynxes have successfully killed adult deer weighing to at least 150 kg (330 lb).
+
+
+=== Reproduction ===
+
+The mating season of the Eurasian lynx lasts from January to April. The female typically comes into oestrus only once during this period, lasting from four to seven days. If the first litter is lost, a second period of oestrus is common. It does not appear to be able to control its reproductive behaviour based on prey availability. Gestation lasts from 67 to 74 days. Pregnant females construct dens in secluded locations, often protected by overhanging branches or tree roots. The den is lined with feathers, deer hair, and dry grass to provide bedding for the young. At birth, Eurasian lynx kittens weigh 240 to 430 g (8.5 to 15.2 oz) and open their eyes after ten to twelve days. They initially have plain, greyish-brown fur, attaining the full adult colouration around eleven weeks of age. They begin to take solid food at six to seven weeks, when they begin to leave the den, but are not fully weaned for five or six months. The den is abandoned two to three months after the kittens are born, but the young typically remain with their mother until they are around ten months of age. Eurasian lynx reach sexual maturity at two or three years, and have lived for twenty one years in captivity.Females usually have two kittens; litters with more than three kittens are rare.
+
+
+== Predators and interspecies predatory relationships ==
+The primary predators of the lynx are the gray wolf and the wolverine. In Russian forests, gray wolves kill and eat lynx that fail to escape into trees, as evidenced by examination of wolf and lynx trackways in the Central Forest Nature Reserve, and of lynx hair and bones found in wolf stomach contents in the Belovezh Forest. The lynx saves itself from its enemies by quickly climbing a tree or a cliff; it usually lives near a 'stronghold' place and eats its food in a high tree or cliff. Lynx populations decrease when wolves appear in a region such as observed in the Pritelsk region of the Altai Mountains, and lynx are likely to take smaller prey where wolves are active. In eastern Slovakia, after an increase of wolves after World War II, lynx  were observed to move out.However, there is also a reported instance of a male lynx having expelled an adult and apparently healthy male wolf in Belarus in a fight. After the incident the wolf vanished from the record, suggesting that it might have succumbed to the wounds sustained during the fight. Moreover, recent population dynamics and a high mortality rate among wolf cubs in the Naliboki forest might be connected to an increasing lynx population. All in all this suggests that at least locally lynx may dominate wolves, since no signs for predation of wolves on lynx was found. In the Pechora-Ilych Nature Reserve in Russia wolverine predation and consumption of a lynx has been documented, and in the Altai Mountains, the lynx avoids wolverines.The gray wolf, wolverine, as well as the red fox and the eagle owl, are also competitors of the Eurasian lynx for food in the taiga regions of Russia. In years of low hare populations, the competition becomes especially strong, and the lynx is at a disadvantage because its competitors are able to secure other prey more efficiently. This competition may be especially severe in the northern parts of the lynx's range where lynx populations are vastly outnumbered by red fox and even by wolverines. The presence of other large carnivores is one factor limiting their population.In two ecosystems of Anatolia, cannibalism was common and lynx were found to form 5% to 8% of prey biomass in diet. Claws and bones analysed showed that sub-adult lynx were the victims of cannibalism during the mating and spring seasons. Lynx were not found in the sympatrically occurring wolves' diet, however, lynxes themselves were the predator of red foxes, martens, domestic cats and dogs, and golden jackal remains have been found in lynx fecal samples. Sometimes, Siberian tigers have also preyed on lynxes, as evidenced by examination of tiger stomach contents.
+In Sweden, out of 33 deaths of lynx of a population being observed, one was probably killed by a wolverine. Lynx compete for food with the predators described above, and also with the red fox, eagle owls, golden eagles, wild boar (which scavenge from lynx kills), and in the southern part of its range, the snow leopard and leopard as well. Brown bears, although not (so far as is known) a predator of Eurasian lynx, are in some areas a semi-habitual usurpers of ungulate kills by lynxes, not infrequently before the cat has had a chance to consume its kill itself.
+
+
+== Conservation ==
+
+The Eurasian lynx is included on CITES Appendix II and listed as a protected species in the Berne Convention on the Conservation of European Wildlife and Natural Habitats, Appendix III. Hunting lynx is illegal in many range countries, with the exception of Estonia, Latvia, Russia, Armenia and Iraq. Since 2005, the Norwegian government sets national population goals, while a committee of representatives from county assemblies decide on hunting quotas.

+The Iberian lynx (Lynx pardinus) is a wild cat species endemic to the Iberian Peninsula in southwestern Europe. It is listed as Endangered on the IUCN Red List. In the 20th century, the Iberian lynx population had declined because of overhunting, poaching, fragmentation of suitable habitats, and the population decline of its main prey species, the European rabbit (Oryctolagus cuniculus), caused by myxomatosis and rabbit haemorrhagic disease.By the turn of the 21st century, the Iberian lynx was on the verge of extinction, as only 94 individuals survived in two isolated subpopulations in Andalusia in 2002. Conservation measures have been implemented since then, which included improving habitat, restocking of rabbits, translocating,  reintroducing and monitoring Iberian lynxes. By 2012, the population had increased to 326 individuals, to 855 in 2020, and to 1,111 in 2021.It is a monotypic species, and is thought to have evolved from Lynx issiodorensis.
+
+
+== Taxonomy ==
+Felis pardina was the scientific name proposed by Coenraad Jacob Temminck in 1827 who described skins of Iberian lynxes that were killed in the area of the Tagus river in Portugal and were traded in Paris and London.
+It is a monotypic species.
+
+
+=== Phylogeny ===
+The Iberian lynx is thought to have evolved from Lynx issiodorensis.
+The earliest fossil remains of the Iberian lynx date to the Early Pleistocene.The Iberian lynx genetically diverged as a unique species 1.98 to 0.7 million years ago. Its closest living relative is the Eurasian lynx (Lynx lynx) with which it coexisted to a certain degree until the 20th century.
+
+
+== Characteristics ==
+
+The Iberian lynx has a short bright yellowish to tawny coloured spotted fur. The spots vary in shape and size from small round to elongate. They are arranged in lines and decrease in size from the back towards the sides.
+Its head is small with tufted ears and a ruff. Its body is short with long legs and a short tail. Head and body length of males is 74.7–82 cm (29.4–32.3 in) with a 12.5–16 cm (4.9–6.3 in) long tail and a weight of 7–15.9 kg (15–35 lb). Females are smaller with a head-to-body-length of approximately 68.2–77.5 cm (26.9–30.5 in) and a weight of 9.2–10 kg (20–22 lb).
+
+
+== Distribution and habitat ==
+The Iberian lynx was once present throughout the Iberian Peninsula. In the 1950s, the northern population extended from the Mediterranean to Galicia and parts of northern Portugal, and the southern population from central to southern Spain. Populations declined from 15 subpopulations in the 1940s to only two subpopulations in the early 1990s, most noticeably in Montes de Toledo and Sierra Morena. Before 1973, it was present in Sierra de Gata, Montes de Toledo, eastern Sierra Morena, Sierra de Relumbrar and coastal plains in the Doñana area. Between the early 1960s and 2000, it has lost about 80% of its former range. In 2012, it was restricted to very limited areas in southern Spain, with breeding only confirmed in Sierra Morena and Doñana coastal plains. As of 2014, its range included the Sierra Morena and Montes de Toledo of Castilla-La Mancha and the Matachel Valley of Extremadura in Spain, and the Guadiana Valley in Portugal.Fossil remains indicate that the Iberian lynx had a wider range during the Late Pleistocene and early Holocene. Five lynx remains found in Arene Candide in northern Italy date to about 24,820–18,620 before present. One specimen found in Cabias cave in southern France was radiocarbon dated to 3780±90 before present. In 2021, a large concentration of Iberian lynxes dating to 40,000 years ago were identified for the first time in southern Italy, at the fossil site of Ingarano in Apulia.The Iberian lynx prefers heterogeneous environments of open grassland mixed with dense shrubs such as strawberry tree, mastic, and juniper, and trees such as holm oak and cork oak. It is now largely restricted to mountainous areas.
+
+
+== Behaviour and ecology ==
+The Iberian lynx marks its territory with its urine, scratch marks on the barks of trees, and scat. The home ranges of adults are stable over many years.
+Camera trapping surveys in the eastern Sierra Morena Mountains between 1999 and 2008 revealed that six females had home ranges of 5.2–6.6 km2 (2.0–2.5 sq mi). Four males in the area had home ranges of 11.8–12.2 km2 (4.6–4.7 sq mi).
+
+
+=== Diet and hunting ===
+
+The Iberian lynx preys foremost on the European rabbit (Oryctolagus cuniculus) for the bulk of its diet, supplemented by red-legged partridge (Alectoris rufa), rodents and to a smaller degree also on wild ungulates.
+It sometimes preys on young fallow deer (Dama dama), roe deer (Capreolus capreolus), European mouflon (Ovis aries musimon), and ducks. A male requires one rabbit per day, while a female raising kittens will eat three per day.The species has low adaptability — it continued to rely heavily on rabbits (75% of its food intake) despite the latter's repeated population crashes due to myxomatosis and rabbit haemorrhagic disease.It competes for prey with the Iberian wolf (Canis lupus signatus), red fox (Vulpes vulpes), the Egyptian mongoose (Herpestes ichneumon), and the European wildcat (Felis silvestris). Also, it often kills other smaller carnivores such as the aforementioned red fox, Egyptian mongoose and common genet (Genetta genetta).
+
+
+=== Reproduction ===
+
+The kittens become independent at 7 to 10 months old, but remain with the mother until around 20 months old. Survival of the young depends heavily on the availability of prey species. In the wild, both males and females reach sexual maturity at the age of one year, though in practice they rarely breed until a territory becomes vacant; one female was known not to breed until five years old when its mother died. The maximum longevity in the wild is 13 years.Difficulty in finding mates has led to more inbreeding, which results in fewer kittens and a greater rate of non-traumatic death. Inbreeding leads to lower semen quality and greater rates of infertility in males, hindering efforts to increase the species' fitness.
+
+
+== Threats ==
+The Iberian lynx is threatened by habitat loss, road accidents, and illegal hunting. Habitat loss is due mainly to infrastructure improvement, urban and resort development and tree mono cultivation, which fragments the lynx's distribution. In the 20th century, rabbit diseases such as myxomatosis and hemorrhagic disease resulted in a dramatic decline of its main prey. Illegal traps set for rabbits and foxes were leading causes for lynx fatality in the 1990s.
+Every year, several Iberian lynxes die when trying to cross highways with heavy traffic. In 2013, 14 Iberian lynxes died on roads, and 21 in 2014.In 2007, several individuals died of feline leukemia.In 2013, it was reported that the Iberian lynx possesses antibiotic resistant bacteria within its digestive tract, which may lead to more dangerous and difficult-to-treat infections, and decrease its fitness. Climate change may threaten the Iberian lynx, as it is not able to adapt well to a climate change. It may be induced to disperse to areas with a more suitable climate but fewer rabbits, a circumstance that may contribute to higher mortality.
+
+
+== Conservation ==
+
+The Iberian lynx is fully protected. It is listed on CITES Appendix I, on Appendix II of the Berne Convention on the Conservation of European Wildlife and Natural Habitats and on Annexes II and IV of the Habitats Directive of the European Union. It has been listed as Endangered on the IUCN Red List since 2014.Conservation measures include restoring its native habitat, maintaining the wild rabbit population, reducing unnatural causes of death, and releasing captive bred individuals. 
+The Spanish National Commission for the Protection of Nature endorsed the Iberian Lynx Ex Situ Conservation Breeding Program to serve as a "safety net" by managing the captive population and also to "help establish new Iberian lynx free-ranging populations through reintroduction programmes." Before release of captive-bred cats, their natural habit may be simulated to prepare them for life in the wild. A 2006 study used a non-intrusive monitoring system involving cameras to monitor the demographics of both lynxes and rabbits residing in Sierra Morena. Supplemental food sources could be provided if wild rabbits suffered a decline.Management efforts are being developed to conserve and restore the animal's native range. Officials intending to release captive-bred lynx look for areas of appropriate habitat, rabbit abundance, and acceptance by the local human population. About 90 million euros was spent on various conservation measures between 1994 and 2013. The European Union contributes up to 61% of funding.
+
+
+=== Reintroduction programme ===
+
+Beginning in 2009, the Iberian lynx was reintroduced into Guadalmellato, resulting in a population of 23 in 2013. Since 2010, the species has also been released in Guarrizas. Discussions were held with the Ministry of Environment on plans for releases in the Campanarios de Azaba area near Salamanca. In April 2013, it was reported that Andalusia's total wild population—only 94 in 2002—had tripled to 309 individuals. In July 2013, environmental groups confirmed the presence of a wild-born litter in the Province of Cáceres (Extremadura). A study published in July 2013 in Nature Climate Change advised that reintroduction programs take place in northern Iberia, suggesting that climate change would threaten rabbits in the south.On 26 November 2014, 3 Iberian lynxes were released in the Montes de Toledo; one of them later traveled near Aranjuez, in the Madrid region, the first time in 40 years.The presence of Iberian lynxes in Portugal, particularly in the south, has been verified. In 2014, the Institute for Nature Conservation and Forests signed contracts securing 2,000 hectares of land for Portugal's reintroduction project.
+In 2015, 10 captive-bred Iberian lynxes were released into Guadiana Valley Natural Park and surrounding areas in southeastern Portugal's Guadiana Valley. By the end of 2015, there were 400 lynx on the Iberian peninsula, the vast majority in Andalusia, in southern Spain, but with smaller new populations in the hills near Toledo, in Extremadura (south-western Spain) and in southern Portugal.The reintroduction of Iberian lynx in Portugal has been a success; from 17 animals that were reintroduced, 12 have already established territories.Since a 2007 outbreak of feline leukemia virus (FeLV), wild lynxes are tested periodically for possible disease. September–December 2013 samples were negative for FeLV but one male became the first of his species to test positive for feline immunodeficiency virus and was placed into quarantine.
+
+
+=== Captive breeding ===
+
+In 2002, the Jerez Zoo confirmed it had three females and was developing a plan for a captive breeding program. One of those females was Saliega, captured as a kitten in April 2002. She became the first Iberian lynx to breed in captivity, giving birth to three healthy kittens on 29 March 2005 at the El Acebuche Breeding Center, in the Doñana National Park in Huelva, Spain. Over the following years, the number of births grew and additional breeding centers were opened. In March 2009, it was reported that 27 kittens had been born since the beginning of the program. In 2009, the Spanish government planned to build a €5.5 million breeding center in Zarza de Granadilla.In Portugal, the Centro Nacional de Reprodução do Lince-Ibérico established a breeding center near Silves, Portugal, and has since nurtured 122 individuals all born in the breeding center, of which 89 survived. 73 of them were reintroduced in the wild. Reintroduction takes place in Mértola and Serpa in the Guadiana Valley. As of 2020, there are around 140 individuals in the wild in Portugal spread through an area of approximately 50,000 hectares, 50 of them are cubs.There were 14 surviving kittens in 2008 and 15 in 2009. In 2010, intense rain and health issues resulted in lower reproductive success, i.e. 14 born, eight surviving. But the next year, breeding centers recorded 45 births with 26 surviving kittens. In 2012, breeding centers in Portugal and Spain reported a total of 44 survivors from 59 births, while 2013 saw a total of 44 survivors out of 53 born. In 2017, the total population of Iberian lynx reached 475 specimens. In February 2019, the total population was estimated to grow to around 650 individuals.
+
+In March 2013, it was reported that Iberian lynx embryos and oocytes had been collected and preserved for the first time. They were collected from Saliega and another female—both sterilized and retired from the breeding program—by Berlin's Leibniz Institute for Zoo and Wildlife Research and stored in liquid nitrogen at the Museo Nacional de Ciencias Naturales in Madrid for possible future breeding. In July 2014, the MNCN-CSIC announced they had produced sperm cells from the testicular tissue of sexually immature lynx.Iberian lynxes are kept at Jerez Zoo, at Lisbon Zoo since December 2014, and since July 2016 at the Madrid Zoo.
+
+
+== Genetic research ==
+The genetic diversity of the Iberian lynx is lower than in any other genetically impoverished felid, which is a consequence of fragmentation, a population bottleneck, and isolation of population units. Iberian lynxes in Doñana and Andujar differ genetically at microsatellite markers. Samples collected in Doñana exhibited a high degree of inbreeding as this unit was isolated for a long time.

+The Japanese macaque (Macaca fuscata), also known as the snow monkey, is a terrestrial Old World monkey species that is native to Japan. Colloquially, they are referred to as "snow monkeys" because some live in areas where snow covers the ground for months each year – no other non-human primate lives further north, nor in a colder climate. Individuals have brownish grey fur, pinkish-red faces, and short tails. Two subspecies are known.In Japan, the species is known as Nihonzaru (ニホンザル, a combination of Nihon 日本 "Japan" + saru 猿 "monkey") to distinguish it from other primates, but the Japanese macaque is very familiar in Japan — as it is the only species of monkey in Japan — so when Japanese people simply say saru, they usually have the Japanese macaque in mind.
+
+
+== Physical characteristics ==
+
+The Japanese macaque is sexually dimorphic. Males weigh on average 11.3 kg (25 lb), while females average 8.4 kg (19 lb). Macaques from colder areas tend to weigh more than ones from warmer areas. The average height for males is 57.0 cm (22.4 in), while the average female height is 52.3 cm (20.6 in). The size of their brain is approximately 95 g (3.4 oz). Japanese macaques have short stumps for tails that average 92.5 mm (3.64 in) in males and 79.1 mm (3.11 in) in females. The macaque has a pinkish face and posterior. The rest of its body is covered in brown or greyish hair. The coat of the macaque is well-adapted to the cold and its thickness increases as temperatures decrease. The macaque can cope with temperatures as low as −20 °C (−4 °F).Macaques mostly move on all fours. They are semiterrestrial, with females spending more time in the trees and males spending more time on the ground. Macaques are known to leap. They are very good swimmers and have been reported to swim a distance of more than half a kilometer. The lifespan of Japanese macaques is up to 32 years for females and up to 28 years for males, which is high when compared to what typically is seen in other macaque species.
+
+
+== Behavior ==
+
+
+=== Group structure ===
+
+Japanese macaques live in matrilineal societies, and females stay in their natal groups for life, while males move out before they are sexually mature. Macaque groups tend to contain several adults of both genders. In addition, a Japanese macaque troop contains several matrilines. These matrilines may exist in a dominance hierarchy with all members of a specific group ranking over members of a lower-ranking group. Temporary all-male groups also exist, composed of those who have recently left their natal groups and are about to transfer to another group. However, many males spend ample time away from any group, and may leave and join several groups.
+
+Females of the troop exist in a stable dominance hierarchy and a female's rank depends on that of her mother. Younger females tend to rank higher than their older siblings. Higher-ranking matrilines have greater social cohesion. Strong relationships with dominant females can allow dominant males to retain their rank when they otherwise would not. Males within a group normally have a dominance hierarchy, with one male having alpha status. The dominance status of male macaques usually changes when a former alpha male leaves or dies. Other ways in which status of male hierarchy changes, is when an alpha male loses his rank or when a troop splits, leaving a new alpha male position open. The longer a male is in a troop, the higher his status is likely to be.Females typically maintain both social relationships and hygiene through grooming. Grooming occurs regardless of climate or season. Females who are matrilineally related groom each other more often than unrelated individuals. Females will groom unrelated females to maintain group cohesion and social relationships between different kinships in a troop. Nevertheless, a female will only groom a limited number of other females, even if the group expands. Females will groom males, usually for hygienic purposes, but that behavior also may serve to attract dominant males to the group. Mothers pass their grooming techniques to their offspring, most probably through social rather than genetic means, as a cultural characteristic.
+
+
+==== Documented female troop leadership ====
+Yakei is a female who rose to leadership of her troop at Takasakiyama Natural Zoological Garden in 2021. Her troop consists of 677 Japanese macaque monkeys who live in a sanctuary that was established in 1952 at the zoological garden. At age nine, she overthrew the dominant males in her troop and displaced her high-ranking mother as well. She became the first female leader of the troop during its recorded history of seventy years. Yakei has retained her leadership position through her first breeding season that had been thought to be a time when she might have been challenged successfully. Both scientific and popular interest is leading to extensive coverage of Yakei's behavior.
+
+
+=== Mating and parenting ===
+
+A male and female macaque form a pair bond and mate, feed, rest, and travel together during the mating season, and on average, this relationship typically lasts 16 days. Females enter into consortships with an average of four males a season. Higher-ranking males have longer consortships than their subordinates. In addition, higher-ranking males try to disrupt consortships of lower-ranking males. Females may choose to mate with males of any rank. However, dominant males mate more frequently than others, as they are more successful in mate guarding. The female decides whether mating takes place. In addition, a dominant position does not mean a male will successfully mate with a female. Males may join other troops temporarily during the mating season and mate with those females.During the mating season, the face and genitalia of males redden and their tails stand erect, and the faces and anogenital regions of females turn scarlet. Macaques copulate both on the ground and in the trees. Roughly one in three copulations leads to ejaculation. Macaques signal when they are ready to mate by looking backward over a shoulder, staying still, or walking backward toward their potential partner. A female emits a "squawk", a "squeak", or produces an atonal "cackle" during copulation. Males have no copulatory vocalizations. 
+Females engage in same-sex mounting unrelated to the mating season and therefore, are mounted more often by other females than by males. This behavior has led to proposals in literature that female Japanese macaques are generally bisexual, rather than preferentially homo- or heterosexual.
+
+A macaque mother moves to the periphery of her troop to give birth in a secluded spot, unless the group is moving, when the female must stay with it. Macaques usually give birth on the ground. Infants are born with dark-brown hair. A mother and her infant tend to avoid other troop members. The infants consume their first solid food at five to six weeks old, and by seven weeks, can forage independently from their mothers. A mother carries her infant on her belly for its first four weeks. After this time, the mother carries her infant on her back, as well. Infants continue to be carried past a year. The mother may socialize again very slowly. However, alloparenting has been observed, usually by females who have not had infants of their own. Male care of infants occurs in some groups, but not in others; when they do, usually, older males protect, groom, and carry an infant as a female would.Infants have fully developed their locomotive abilities within three to four months. When an infant is seven months old, its mother discourages suckling; full weaning happens by its eighteenth month. 
+In some populations, male infants tend to play in larger groups more often than females. However, female infants have more social interaction than their male counterparts, and female infants will associate with individuals of all ages and genders. When males are two years old, they prefer to associate with other males around the same age.
+
+
+=== Communication ===
+During feeding or moving, Japanese macaques often emit sounds that are called "coos". These vocalizations most likely serve to keep the troop together and strengthen social relations among females. Macaques usually respond to coos with coos of their own. Coos also are uttered before grooming along with vocalizations identified as "girney" calls. Variants of the "girney" calls are made in different contexts. This call also serves as appeasement between individuals in aggressive encounters. Macaques have alarm calls for alerting to danger and other calls to signal estrus that sound similar to danger alerts. Threat calls are heard during aggressive encounters and are often uttered by supporters of those involved in antagonistic interactions. The individual being supported supports those callers in the future.
+
+
+=== Intelligence and culture ===
+
+The Japanese macaque is an intelligent species. Researchers studying this species at Koshima Island in Japan left sweet potatoes out on the beach for them to eat, then witnessed one female, named Imo (Japanese for yam or potato), washing the food off with river water rather than brushing it off as the others were doing, and later even dipping her clean food into salty seawater. After a while, other members of her troop started to copy her behavior. This trait was then passed on from generation to generation, until eventually all except the oldest members of the troop were washing their food and even seasoning it in the sea. Similarly, she was the first observed balling up wheat with air pockets and soil, throwing it all into the water, and waiting for the wheat to float back up free from the soil to consume it. An altered misaccount of this incident is the basis for the "hundredth monkey" effect. That behavior also spread among her troop members. 
+The macaque has other unusual behaviours, including bathing together in hot springs and rolling snowballs for fun. Also, in recent studies, the Japanese macaque has been found to develop different accents, similar to human cultures. Macaques in areas separated by only a few hundred miles may have very different pitches in their calls, their form of communication. The Japanese macaque has been involved in many studies concerning neuroscience and also is used in drug testing.
+
+
+== Ecology ==
+The Japanese macaque is diurnal. In colder areas, from autumn to early winter, macaques feed in between different activities. In the winter, macaques have two to four feeding bouts each day, with fewer daily activities. In the spring and summer, they have two or three bouts of feeding daily. In warmer areas such as Yakushima, daily activities are more varied. The typical day for a macaque is 20.9% inactive, 22.8% traveling, 23.5% feeding, 27.9% social grooming, 1.2% self-grooming, and 3.7% other activities. Macaques usually sleep in trees, but they also sleep on the ground, as well as on or near rocks and fallen trees. During the winter, macaques huddle together for warmth on sleeping grounds. Macaques at Jigokudani Monkey Park are notable for visiting the hot springs in the winter to warm up.
+
+
+=== Diet ===
+
+The Japanese macaque is omnivorous and eats a variety of foods. More than 213 species of plants are included in the macaque's diet. They also eat insects, bark, and soil. On Yakushima Island, fruit, mature leaves, and fallen seeds are primarily eaten. The macaque also eats fungi, ferns, invertebrates, and other parts of plants. In addition, in Yakushima, their diets vary seasonally with fruits being eaten in the summer and herbs being eaten in the winter. Farther north, macaques mostly eat seasonal foods such as fruit and nuts to store fat for the winter, when food is scarce. On the northern island of Kinkasan, macaques mostly eat fallen seeds, herbs, young leaves, and fruits. When preferred food items are not available, macaques dig up underground plant parts (roots or rhizomes) or eat soil and fish.
+
+
+== Distribution and habitat ==
+The Japanese macaque is the northernmost-living non-human primate. It is found on three of the four main Japanese islands: Honshu, Shikoku, and Kyushu. The northernmost populations live on the Shimokita Peninsula, the northernmost point of Honshu. Several of Japan's smaller islands are inhabited by macaques as well. The southernmost population living on Yakushima Island is a subspecies of the mainland macaques, M. fuscata yakui. A study in 1989 estimated the total population of wild Japanese macaques to be 114,431 individuals.The Japanese macaque lives in a variety of habitats. It inhabits subtropical forests in the southern part of its range and subarctic forests in mountainous areas in the northern part of its range. It can be found in both warm and cool forests, such as the deciduous forests of central and northern Japan and the broadleaf evergreen forests in the southwest of the islands. Warm temperate evergreen and broadleaf forests and cool temperate deciduous broadleaf forests are the most important habitats for macaques.In 1972, a troop of approximately 150 Japanese macaques was relocated from Kyoto to a primate observatory in southwest Texas, United States. The observatory is an enclosed ranch-style environment and the macaques have been allowed to roam with minimal human interference. At first, many perished in the unfamiliar habitat, which consists of arid brushland. The macaques eventually adapted to the environment, learned to avoid predators (such as eagles, coyotes, and rattlesnakes), and they learned to forage for mesquite beans, cactus fruits, and other foods. The surviving macaques flourished, and by 1995, the troop consisted of 500 to 600 individuals. In 1996, hunters maimed or killed four escaped macaques; as a result, legal restrictions were publicly clarified and funds were raised to establish a new 186-acre (75 ha) sanctuary near Dilley, Texas. In 1999, the Animal Protection Institute took over management of the sanctuary and began to rescue other species of primates. As of 2017, the troop cohabitated with six other species of macaque.
+
+
+== Relationship with humans ==
+
+Traditional human behaviors that are threats to macaques have been slash-and-burn agriculture, use of forest woods for construction and fuel, and hunting. Since World War II, these threats have declined due to social and economic changes in Japan, but other threats have emerged. The replacement of natural forests with lumber plantations is the most serious threat. As human prosperity has grown, macaques have lost their fear of humans and have increased their presence in both rural and urban areas, with one macaque recorded living in central Tokyo for several months. In 2022 the city of Yamaguchi experienced aggression from the monkeys with at least 50 people attacked.
+
+
+=== Cultural depictions ===
+
+The Japanese macaque (snow monkey) has featured prominently in the religion, folklore, and art of Japan, as well as in proverbs and idiomatic expressions in the Japanese language. 
+In Shinto belief, mythical beasts known as raijū sometimes appeared as monkeys and kept Raijin, the god of lightning, company. The "three wise monkeys", who warn people to "see no evil, hear no evil and speak no evil", are carved in relief over the door of the famous Tōshō-gū shrine in Nikkō. 
+The Japanese macaque is a feature of several fairy tales, such as the tale of Momotarō and the fable about The Crab and the Monkey.The monkey is part of the Chinese zodiac. That zodiac has been used for centuries in Japan and led to many representations of the macaque for that figure.
+The creature was sometimes portrayed in paintings of the rich cultural epoch, the Edo period that flourished from 1603 to 1867, as a tangible metaphor for a particular year. The early nineteenth-century artist and samurai, Watanabe Kazan (1793-1841), created a painting of a macaque. The last great master of the ukiyo-e genre of woodblock printing and painting, Tsukioka Yoshitoshi, also featured the macaques in his prints. Also during the Edo period, numerous clasps for kimono or tobacco pouches (collectively called netsuke) were carved in the shape of macaques.Spoken references to macaques abound in the history of Japan. Originating from before his rise to power, the famed samurai, Toyotomi Hideyoshi, was compared to a monkey in appearance and nicknamed Kozaru ("Little Monkey"). In modern Japanese culture, because monkeys are considered to indulge their libido openly and frequently (much the same way as rabbits are thought to in some Western cultures), a man who is preoccupied with sex might be compared to or metaphorically referred to as a monkey, as might a romantically involved couple who are exceptionally amorous.

+The lion-tailed macaque (Macaca silenus), also known as the wanderoo, is an Old World monkey endemic to the Western Ghats of South India.
+
+
+== Characteristics ==
+
+Lion-tailed macaques are covered in black fur, and have a striking gray or silver mane that surrounds their face which can be found in both sexes. The face itself is hairless and black, being pinkish in infants less than a year old. They are named not for their mane, but for their tail, which is long, thin, and naked, with a lion-like, black tail tuft at the tip. The size of their tail is about 25 cm (9.8 in) in length. Their eyes are a shade of hazelnut with highlighting black eyelids. Lion-tailed macaques, like other macaques, have deep cheek pouches useful for storing food, and are quadrupedal with opposable digits. The mane that surrounds its face gives this monkey its German name Bartaffe – "beard ape". With a head-body length of 42–61 cm (17–24 in) and a weight of 2–10 kg (4.4–22.0 lb), it ranks among the smaller macaques species. Offspring are born with lighter faces and no mane, with the adult mane growing in after two months after birth.
+
+
+== Behavior and ecology ==
+
+The lion-tailed macaque is a rainforest dweller, often being found in the upper canopy of tropical moist evergreen forests or monsoon forests. It is diurnal, meaning it is active exclusively in daylight hours. When they’re active, they will spend half the day foraging, and the other half will be spent resting or finding new areas to forage. Unlike other macaques, it typically avoids humans when possible. In group behavior, the lion-tailed macaque is much like other macaques, living in hierarchical groups of usually 10 to 20 members, which usually consist of few males, typically 1-3, and many females. They have a polygynous mating system with no specific breeding season. While there is no specific breeding season, they do tend to breed in the wet season when resources are most abundant.  Little time is spent grooming or playing with others in the group. Of the few males, only one will be the dominant male, who will protect his troop from others and be the one who breeds. It is a territorial animal, defending its area first with loud cries and bared teeth towards the invading troops. If this proves to be fruitless, it brawls aggressively, which can result in severe injuries due to lacerations from their large canines. Other forms of communication come in the form of mounting to show strength, branch shaking to scare off, lip-smacking as a friendly greeting, or yawning with a grimace to indicate dominance.
+
+Lion-tailed macaque behavior is characterized by typical patterns of arboreal living. This patterns involve selectively feeding on a large variety of fruit trees, large interindividual spaces while foraging, and time budgets with high proportion of time devoted to exploration and feeding. Lion-tailed macaques are omnivores, primarily eating indigenous fruits, seeds, flowers, insects, snails, and small vertebrates in virgin forest. Lion-tailed macaques are very important for seed dispersal, and are able to transport seeds long distances by either dropping or defecating seeds. However, due to changes in their environment, adaption to rapid environmental change has occurred in areas of massive selective logging through behavioral modifications and broadening of food choices. These changes involve a large increase in ground foraging and feeding on far more non-native plants and insects.  These feeding changes include fruits, seeds, shoots, pith, flowers, cones, mesocarp, and other parts of many non-indigenous and pioneer plants. In the forests of Kerala they were observed preying on nestlings and eggs of pigeons.Gestation lasts approximately six months. The young are nursed for one year. Sexual maturity is reached at four years for females, and six years for males. The life expectancy in the wild is approximately 20 years, while in captivity is up to 30 years.
+
+
+== Threats ==
+While lion-tailed macaques are preyed on by snakes, raptors, and large carnivores, the impact of natural predators on population size doesn’t compare to their largest threat. The largest threat to the lion-tailed macaque is habitat fragmentation due to large amounts of timber harvesting and exotic plantations, such as tea and coffee. This fragmentation leads to many issues that the lion-tailed macaques are facing. They are struggling to find food, being hit by cars, and being electrocuted by power lines. Due to their low numbers and high levels of fragmentation, they are also highly susceptible to inbreeding, which can cause many genetic issues. Their second largest threat is from humans hunting and trapping them for meat, especially within areas that have primates as their preferred food. There are also many human-primate conflicts occurring now due to macaques venturing out of their forests to find food.
+
+
+== Conservation and Population ==
+
+An assessment in 2003 for IUCN reports 3000–3500 of these animals live scattered over several areas in Tamil Nadu, Kerala, Karnataka. The lion-tailed macaque ranks among the rarest and most threatened primates. Their range has become increasingly isolated and fragmented by the spread of agriculture and tea, coffee, teak and cinchona, construction of water reservoirs for irrigation and power generation, and human settlements to support such activities. They do not live, feed or travel through plantations. Destruction of their habitat and their avoidance of human proximity have led to the drastic decrease of their population.
+From 1977 to 1980, public concern about the endanged status of lion-tailed macaque became the focal point of Save Silent Valley, India's fiercest environmental debate of the decade. From 1993 to 1996, 14 troops were observed in Silent Valley National Park, Kerala, one of the most undisturbed viable habitats left for them. Silent Valley has the largest number of lion tailed macaque in South India. Other protected areas in Kerala include Neyyar Wildlife Sanctuary, Peppara Wildlife Sanctuary, Shendurney Wildlife Sanctuary, Periyar Tiger Reserve and its premises (Gavi and Konni), Eravikulam National Park, Pambadum Shola National Park, Parambikulam Tiger Reserve, Annaimalai Tiger Reserve, New Amarambalam Reserved Forest, Aralam Wildlife Sanctuary and Chimmony Wildlife Sanctuary and Wayanad region.A self-sustainable single population of 32 groups of lion-tailed macaques occurred in Sirsi-Honnavara, Karnataka, the northernmost population of the species.  A local census concluded in 2007, conducted in the Theni District of Tamil Nadu, put their numbers at around 250, which was considered encouraging, because until then, no lion-tailed macaques had been reported in that specific area. The species is also prominently found in the Papanasam part of the Kalakkad Mundanthurai Tiger Reserve of Tirunelveli district, the Palani Hills Wildlife Sanctuary and National Park of Dindigul, the Anaimalai Tiger Reserve of Coimbatore in Tamil Nadu. Many zoos take part in breeding programs which help to secure the survival of this species. About 338 of these macaques are reported to live in zoos. (In July 2021 Australia's Rockhampton Zoo euthanased Australia's last lion-tailed macaque after its companion died of natural causes.)
+However, it is no longer on ‘The World's 25 Most Endangered Primates’ list, after the international body compiling it determined that the local governments in southern India had acted positively to protect it.

+The red-necked wallaby or Bennett's wallaby (Notamacropus rufogriseus) is a medium-sized macropod marsupial (wallaby), common in the more temperate and fertile parts of eastern Australia, including Tasmania. Red-necked wallabies have been introduced to several other countries, including New Zealand, the United Kingdom (in England and Scotland), Ireland, the Isle of Man, France and Germany.
+
+
+== Description ==
+
+Red-necked wallabies are distinguished by their black nose and paws, white stripe on the upper lip, and grizzled medium grey coat with a reddish wash across the shoulders. They can weigh 13.8 to 18.6 kilograms (30 to 41 lb) and attain a head-body length of 90 centimetres (35 in), although males are generally bigger than females. Red-necked wallabies are very similar in appearance to the black-striped wallaby (Notamacropus dorsalis), the only difference being that red-necked wallabies are larger, lack a black stripe down the back, and have softer fur. Red-necked wallabies may live up to nine years.
+
+
+== Distribution and habitat ==
+Red-necked wallabies are found in coastal scrub and sclerophyll forest throughout coastal and highland eastern Australia, from Bundaberg, Queensland to the South Australian border; in Tasmania and on many of the Bass Strait islands. It is unclear which of the Tasmanian islands have native populations as opposed to introduced ones.
+In Tasmania and coastal Queensland, their numbers have expanded over the past 30 years because of a reduction in hunting pressure and the partial clearing of forest to result in a mosaic of pastures where wallabies can feed at night, alongside bushland where they can shelter by day. For not altogether clear reasons, they are less common in Victoria.
+
+
+== Behaviour ==
+
+Red-necked wallabies are mainly solitary but will gather together when there is an abundance of resources such as food, water or shelter. When they do gather in groups, they have a social hierarchy similar to other wallaby species. A recent study has demonstrated that wallabies, as other social or gregarious mammals, are able to manage conflict via reconciliation, involving the post-conflict reunion, after a fight, of former opponents, which engage in affinitive contacts. Red-necked wallabies are mainly nocturnal. They spend most of the daytime resting.A female's estrus lasts 33 days. During courting, the female first licks the male's neck. The male will then rub his cheek against the female's.  Then the male and female will fight briefly, standing upright like two males. After that they finally mate. A couple will stay together for one day before separating. A female bears one offspring at a time; the young stay in the pouch for about 280 days, whereafter females and their offspring stay together for only a month. However, females may stay in the home range of their mothers for life, while males leave at the age of two. Also, red-necked wallabies engage in alloparental care, in which one individual may adopt the child of another. This is a common behavior seen in many other animal species like wolves, elephants, humans, and fathead minnows.
+
+
+=== Diet ===
+Red-necked wallabies diets consists of grasses, roots, tree leaves, and weeds.
+
+
+== Subspecies ==
+There are two or three subspecies.
+
+N. r. banksianus (Quoy & Gaimard, 1825) - red-necked wallaby [Australian mainland]
+N. r. rufogriseus (Desmarest, 1817) sensu lato - Bennett's wallaby, which is sometimes replaced by:
+N. r. fruticus (Ogilby, 1838) [Tasmania]
+N. r. rufogriseus (Desmarest, 1817) sensu stricto [Bass Strait, King Island]The Tasmanian subspecies, Notamacropus rufogriseus rufogriseus, usually known as Bennett's wallaby, is smaller (as island subspecies or species often are), has longer, darker and shaggier fur, and breeds in the late summer, mostly between February and April. They have adapted to living in proximity to humans and can be found grazing on lawns in the fringes of Hobart and other urban areas.
+The mainland Australian subspecies, Notamacropus rufogriseus banksianus, usually known as the red-necked wallaby, breeds all year round. Captive animals maintain their breeding schedules; Tasmanian females that become pregnant out of their normal season delay birth until summer, which can be anywhere up to 8 months later.
+
+
+== Introductions to other countries ==
+
+There are significant introduced populations in the Canterbury Region of New Zealand's South Island. In 1870, several Bennett's wallabies were transported from Tasmania to Christchurch, New Zealand. Two females and one male from this stock were later released at Te Waimate, the property of Waimate's first European settler Michael Studholme.  The year 1874 saw them freed in the Hunters Hills, where over the years their population has dramatically increased. Bennett's wallabies are now resident on approximately 350,000 ha of terrain in the Hunters Hills, including the Two Thumb Range, the Kirkliston Range and the Grampians. They have been declared an animal pest in the Canterbury Region and land occupiers must contain the wallabies within specified areas. Bennett's wallaby is now widely regarded as a symbol of Waimate.
+There are also small colonies in England in the Peak District (Now extinct), Derbyshire (Now extinct), and the Ashdown Forest in East Sussex (Population Unknown). These were established ca. 1900. There are also other sightings frequently spotted in West Sussex and Hampshire and recently YouTuber 'Wildlife With Cookie' found a population in an unknown part of England not associated with the previous mentioned locations. He also went on to locate Wallabies with Albinism in Kenilworth, WarwickshireThere is a small colony of red-necked wallabies on the island of Inchconnachan, Loch Lomond in Argyll and Bute, Scotland. This was founded in 1975 with two pairs taken from the Whipsnade Zoo, and had risen to 26 individuals by 1993.There is a group of red-necked wallabies living wild on the Isle of Man, which are the descendants of numerous escapes from a wildlife park on the island in the 1960s and 1970s. A 2017 study by estimated their number in the vicinity of the wildlife park to be 83 individuals, including a very small number of Parma wallaby.The Baring family, who owned Lambay Island (250 ha (620 acres)), off the eastern coast of Ireland introduced red-necked wallabies to the island in the 1950s and 1960s. In the 1980s, the red-necked wallaby population at the Dublin Zoo was growing out of control. Unable to find another zoo to take them, and unwilling to euthanize them, zoo director Peter Wilson donated seven individuals to the Barings. The animals have thrived since then and the current population is estimated to be between 30 and 50.In France, in the southern part of the Forest of Rambouillet, 50 km (31 mi) west from Paris, there is a wild group of around 50–100 Bennett's wallabies. This population has been present since the 1970s, when some individuals escaped from the zoological park of Émancé after a storm.In Germany, around 10 wallabies live as a wild population in the federated state of Mecklenburg-Vorpommern since 2001.In October 2014, three captive Bennett's wallabies escaped into the wild in northern Austria and one of them roamed the area for three months before being recaptured, surprisingly surviving the harsh winter there. The case attracted media attention, as it humorously defeated the popular slogan "There are no kangaroos in Austria."

+The red kangaroo (Osphranter rufus) is the largest of all kangaroos, the largest terrestrial mammal native to Australia, and the largest extant marsupial. It is found across mainland Australia, except for the more fertile areas, such as southern Western Australia, the eastern and southeastern coasts, and the rainforests along the northern coast.
+
+
+== Taxonomy ==
+The initial description of the species by A.G. Desmarest was published in 1822. The type location was given as an unknown location west of the Blue Mountains.
+The author assigned the new species to the genus Kangurus. In 1842, Gould reassigned the species to the genus Osphranter,
+a taxon later submerged as a subgenus of Macropus. A taxonomic restructure in 2015 in Taxonomy of Australian Mammals by Jackson and Groves
+promoted Osphranter back to genus level, redefining the red kangaroo, among others, as species within the genus Osphranter. This was further supported by genetic analysis in 2019.
+
+
+== Description ==
+
+This species is a very large kangaroo with long, pointed ears and a square shaped muzzle [snout/nose]. They are sexually dimorphic as the males have short, red-brown fur, fading to pale buff below and on the limbs. Females are smaller than males and are blue-grey with a brown tinge, pale grey below, although arid zone females are coloured more like males. It has two forelimbs with small claws, two muscular hind-limbs, which are used for jumping, and a strong tail which is often used to create a tripod when standing upright. 
+Males grow up to a head-and-body length of 1.3–1.6 m (4.3–5.2 ft) with a tail that adds a further 1.2 m (3.9 ft) to the total length and are referred to by Australians as "Big Reds". Females are considerably smaller, with a head-and-body length of 85–105 cm (33–41 in) and tail length of 65–85 cm (26–33 in). Females can weigh from 18 to 40 kg (40 to 88 lb), while males typically weigh about twice as much at 55 to 90 kg (121 to 198 lb). The average red kangaroo stands approximately 1.5 m (4.9 ft) tall to the top of the head in upright posture. Large mature males can stand more than 1.8 m (5.9 ft) tall, with the largest confirmed one having been around 2.1 m (6.9 ft) tall and weighed 91 kg (201 lb).The red kangaroo maintains its internal temperature at a point of homeostasis about 36 °C (97 °F) using a variety of physical, physiological, and behavioural adaptations. These include having an insulating layer of fur, being less active and staying in the shade when temperatures are high, panting, sweating, and licking its forelimbs.
+The red kangaroo's range of vision is approximately 300° (324° with about 25° overlap), due to the position of its eyes.
+
+
+== Locomotion ==
+The red kangaroo's legs work much like a rubber band, with the Achilles tendon stretching as the animal comes down, then releasing its energy to propel the animal up and forward, enabling the characteristic bouncing locomotion. They can reach speeds of around 60 km/h (37 mph). The males can cover 8–9 m (26.2–29.5 ft) in one leap while reaching heights of 1.8–3 m (5.9–9.8 ft), though the average is 1.2–1.9 m (3.9–6.2 ft).
+
+
+== Ecology and habitat ==
+
+The red kangaroo ranges throughout western and central Australia. Its range encompasses scrubland, grassland, and desert habitats. It typically inhabits open habitats with some trees for shade. Red kangaroos are capable of conserving enough water and selecting enough fresh vegetation to survive in an arid environment. The kangaroo's kidneys efficiently concentrate urine, particularly during summer. Red kangaroo primarily eat green vegetation, particularly fresh grasses and forbs, and can get enough even when most plants look brown and dry. One study of kangaroos in Central Australia found that green grass makes up 75–95% of the diet, with Eragrostis setifolia dominating at 54%. This grass continues to be green into the dry season. Kangaroos also primarily consumed this species, along with Enneapogon avanaceus, in western New South Wales where they comprised much as 21–69% of its diet according to a study. During dry times, kangaroos search for green plants by staying on open grassland and near watercourses. While grasses and forbs are preferred, red kangaroos will also eat certain species of chenopods, like Bassia diacantha and Maireana pyramidata, and will even browse shrubs when its favoured foods are scarce. However, some perennial chenopods, such as round-leaf chenopod Kochia are avoided even when abundant.
+
+At times, red kangaroos congregate in large numbers; in areas with much forage, these groups can number as much as 1,500 individuals. Red kangaroos are mostly crepuscular and nocturnal, resting in the shade during the day. However, they sometimes move about during the day. Red kangaroos rely on small saltbushes or mulga bushes for shelter in extreme heat rather than rocky outcrops or caves. Grazing takes up most of their daily activities. Like most kangaroo species, they are mostly sedentary, staying within a relatively well-defined home range. However, great environmental changes can cause them to travel great distances. Kangaroos in New South Wales have weekly home ranges of 258–560 ha, with the larger areas belonging to adult males. When forage is poor and rainfall patchy, kangaroos will travel 25–30 km to more favourable feeding grounds. Another study of kangaroos in central Australia found that most of them stay close to remaining vegetation but disperse to find fresh plants after it rains. The red kangaroo is too big to be subject to significant non-human predation. They can use their robust legs and clawed feet to defend themselves from attackers with kicks and blows. However, dingoes and eagles can kill and eat joeys. Joeys are thus protected in their mother's pouch. The red kangaroo does have some major predators, like crocodiles. Extinct predators include the marsupial lion, the thylacine, Megalania, the locally extinct komodo dragon and the wonambi. Kangaroos are adept swimmers, and often flee into waterways if threatened by a predator. If pursued into the water, a kangaroo may use its forepaws to hold the predator underwater so as to drown it.
+
+
+== Behaviour ==
+
+Red kangaroos live in groups of 2–4 members. The most common groups are females and their young. Larger groups can be found in densely populated areas and females are usually with a male. Membership of these groups is very flexible, and males (boomers) are not territorial, fighting only over females (flyers) that come into heat. Males develop proportionately much larger shoulders and arms than females. Most agonistic interactions occur between young males, which engage in ritualised fighting known as boxing. They usually stand up on their hind limbs and attempt to push their opponent off balance by jabbing him or locking forearms. If the fight escalates, they will begin to kick each other. Using their tail to support their weight, they deliver kicks with their powerful hind legs. Compared to other kangaroo species, fights between red kangaroo males tend to involve more wrestling. Fights establish dominance relationships among males, and determine who gets access to estrous females. Dominant males make agonistic behaviours and more sexual behaviours until they are overthrown. Displaced males live alone and avoid close contact with others.
+
+
+=== Reproduction ===
+
+The red kangaroo breeds all year round. The females have the unusual ability to delay the birth of their baby until their previous joey has left the pouch. This is known as embryonic diapause. Copulation may last 25 minutes. The red kangaroo has the typical reproductive system of a kangaroo. The neonate emerges after only 33 days. Usually only one young is born at a time. It is blind, hairless, and only a few centimetres long. Its hind legs are mere stumps; it instead uses its more developed forelegs to climb its way through the thick fur on its mother's abdomen into the pouch, which takes about three to five minutes. Once in the pouch, it fastens onto one of the two teats and starts to feed. Almost immediately, the mother's sexual cycle starts again. Another egg descends into the uterus and she becomes sexually receptive. Then, if she mates and a second egg is fertilised, its development is temporarily halted. Meanwhile, the neonate in the pouch grows rapidly. After approximately 190 days, the baby (called a joey) is sufficiently large and developed to make its full emergence out of the pouch, after sticking its head out for a few weeks until it eventually feels safe enough to fully emerge. From then on, it spends increasing time in the outside world and eventually, after around 235 days, it leaves the pouch for the last time. While the young joey will permanently leave the pouch at around 235 days old, it will continue to suckle until it reaches about 12 months of age. A doe may first reproduce as early as 18 months of age and as late as five years during drought, but normally she is two and a half years old before she begins to breed.
+
+The female red kangaroo is usually permanently pregnant except on the day she gives birth; however, she has the ability to freeze the development of an embryo until the previous joey is able to leave the pouch. This is known as embryonic diapause, and will occur in times of drought and in areas with poor food sources. The composition of the milk produced by the mother varies according to the needs of the joey. In addition, red kangaroo mothers may "have up to three generations of offspring simultaneously; a young-at-foot suckling from an elongated teat, a young in the pouch attached to a second teat and a blastula in arrested development in the uterus".The red kangaroo has also been observed to engage in alloparental care, a behaviour in which a female may adopt another female's joey. This is a common parenting behaviour seen in many other animal species like wolves, elephants and fathead minnows.
+
+
+== Relationship with humans ==
+
+The red kangaroo is an abundant species and has even benefited from the spread of agriculture and creation of man-made waterholes. However, competition with livestock and rabbits poses a threat. It is also sometimes shot by farmers as a pest, although a "destruction permit" is required from the relevant state government.Kangaroos dazzled by headlights or startled by engine noise often leap in front of vehicles, severely damaging or destroying smaller or unprotected vehicles. The risk of harm to vehicle occupants is greatly increased if the windscreen is the point of impact. As a result, "kangaroo crossing" signs are commonplace in Australia.
+Peak times for kangaroo/vehicle crashes are between 5:00 PM and 10:00 PM, in winter, and after extended dry-weather spells.
+
+
+=== Commercial use ===
+Like all Australian wildlife, the red kangaroo is protected by legislation, but it is so numerous that there is regulated harvest of its hide and meat. Hunting permits and commercial harvesting are controlled under nationally approved management plans, which aim to maintain red kangaroo populations and manage them as a renewable resource. Harvesting of kangaroos is controversial, particularly due to the animal's popularity.In the year 2000, 1,173,242 animals were killed. In 2009 the government put a limit of 1,611,216 for the number of red kangaroos available for commercial use. The kangaroo industry is worth about A$270 million each year, and employs over 4000 people.
+The kangaroos provide meat for both humans and pet food. Kangaroo meat is very lean with only about 2% fat. Their skins are used for leather.

+The reticulated python (Malayopython reticulatus) is a python species native to South and Southeast Asia. It is the world's longest snake, and is among the three heaviest. It is listed as least concern on the IUCN Red List because of its wide distribution. In several countries in its range, it is hunted for its skin, for use in traditional medicine, and for sale as pets.It is an excellent swimmer, has been reported far out at sea, and has colonized many small islands within its range.
+Like all pythons, it is a non-venomous constrictor. Adult humans have been killed (and in at least two reported cases, eaten) by reticulated pythons.
+
+
+== Taxonomy ==
+The reticulated python was first described in 1801 by German naturalist Johann Gottlob Theaenus Schneider, who described two zoological specimens held by the Göttingen Museum in 1801 that differed slightly in colour and pattern as separate species—Boa reticulata and Boa rhombeata. The specific name, reticulatus, is Latin meaning "net-like", or reticulated, and is a reference to the complex color pattern. The generic name Python was proposed by French naturalist François Marie Daudin in 1803. American zoologist Arnold G. Kluge performed a cladistics analysis on morphological characters and recovered the reticulated python lineage as sister to the genus Python, hence not requiring a new generic name in 1993.In a 2004 genetics study using cytochrome b DNA, Robin Lawson and colleagues discovered the reticulated python as sister to Australo-Papuan pythons, rather than Python molurus and relatives. Raymond Hoser erected the genus Broghammerus for the reticulated python in 2004, naming it after German snake expert Stefan Broghammer, on the basis of dorsal patterns distinct from those of the genus Python, and a dark mid-dorsal line from the rear to the front of the head, and red or orange (rather than brown) iris colour. In 2008, Lesley H. Rawlings and colleagues reanalysed Kluge's morphological data and combined it with genetic material, and found the reticulated clade to be an offshoot of the Australo-Papuan lineage as well. They adopted and redefined the genus name Broghammerus.However, this and numerous other names by the same author were criticized by several authors, who proposed ignoring them for the purposes of nomenclature. R. Graham Reynolds and colleagues subsequently described the genus Malayopython for this species and its sister species, the Timor python, calling the Timor python M. timoriensis. Hoser has since said that the Malayopython name is a junior synonym of Broghammerus, thus it should not be recognized by the International Code of Zoological Nomenclature. Neither of these proposed reclassifications has been recognized by the ITIS, but Malayopython has been recognized by a number of subsequent authors and the Reptile Database.
+
+
+=== Subspecies ===
+Three subspecies have been proposed:
+
+M. r. reticulatus (Schneider, 1801) – Asiatic reticulated python
+M. r. jampeanus Auliya et al., 2002 – Kayaudi reticulated python or Tanahjampean reticulated python, about half the length, or according to Auliya et al. (2002), not reaching much more than 2 m (6 ft 7 in) in length. Found on Tanahjampea in the Selayar Archipelago south of Sulawesi. Closely related to M. r. reticulatus of the Lesser Sundas.
+M. r. saputrai Auliya et al., 2002 – Selayer reticulated python, occurs on Selayar Island in the Selayar Archipelago and also in adjacent Sulawesi. This subspecies represents a sister lineage to all other populations of reticulated pythons tested. According to Auliya et al. (2002) it does not exceed 4 m (13 ft 1 in) in length.The latter two are dwarf subspecies. Apparently, the population of the Sangihe Islands north of Sulawesi represents another such subspecies, which is basal to the P. r. reticulatus plus P. r. jampeanus clade, but it is not yet formally described.The proposed subspecies M. r. "dalegibbonsi", M. r. "euanedwardsi", M. r. "haydnmacphiei", M. r. "neilsonnemani", M. r. "patrickcouperi", and M. r. "stuartbigmorei" have not found general acceptance.
+
+
+== Characteristics ==
+
+The reticulated python has smooth dorsal scales that are arranged in 69–79 rows at midbody. Deep pits occur on four anterior upper labials, on two or three anterior lower labials, and on five or six posterior lower labials.The reticulated python is the largest snake native to Asia. More than a thousand wild reticulated pythons in southern Sumatra were studied, and estimated to have a length range of 1.5 to 6.5 m (4 ft 11 in to 21 ft 4 in), and a weight range of 1 to 75 kg (2 lb 3 oz to 165 lb 6 oz). Reticulated pythons with lengths more than 6 m (19 ft 8 in) are rare, though according to the Guinness Book of World Records, it is the only extant snake to regularly exceed that length. One of the largest scientifically measured specimens, from Balikpapan, East Kalimantan, Indonesia, was measured under anesthesia at 6.95 m (22 ft 10 in), and weighed 59 kg (130 lb 1 oz) after not having eaten for nearly 3 months.The specimen once widely accepted as the largest-ever "accurately" measured snake, that being Colossus, a specimen kept at the Highland Park Zoo (now the Pittsburgh Zoo and PPG Aquarium) in Pittsburgh, Pennsylvania, during the 1950s and early 1960s, with a peak reported length of 8.7 metres (28 ft 7 in) from a measurement in November 1956, was later shown to have been substantially shorter than previously reported. When Colossus died on 14 April 1963, its body was deposited in the Carnegie Museum of Natural History. At that time, its skeleton was measured and found to be 20 ft 10 in (6.35 m) in total length, and the length of its fresh hide was measured as 23 ft 11 in (7.29 m) – both measurements being significantly shorter than what had been previously estimated in 1956. The hide tends to stretch from the skinning process, thus may be longer than the snake from which it came – e.g., by roughly 20–40% or more. The previous reports had been constructed by combining partial measurements with estimations to compensate for "kinks", since completely straightening an extremely large live python is virtually impossible. Because of these issues, a 2012 journal article concluded, "Colossus was neither the longest snake nor the heaviest snake ever maintained in captivity." Too large to be preserved with formaldehyde and then stored in alcohol, the specimen was instead prepared as a disarticulated skeleton. The hide was sent to a laboratory to be tanned, but it was either lost or destroyed, and now only the skull and selected vertebrae and ribs remain in the museum's collection. Considerable confusion exists in the literature over whether Colossus was male or female (females tend to be larger).
+Numerous reports have been made of larger snakes, but since none of these was measured by a scientist nor any of the specimens deposited at a museum, they must be regarded as unproven and possibly erroneous. In spite of what has been, for many years, a standing offer of a large financial reward (initially $1,000, later raised to $5,000, then $15,000 in 1978 and $50,000 in 1980) for a live, healthy snake 30 ft (9.14 m) or longer by the New York Zoological Society (later renamed as the Wildlife Conservation Society), no attempt to claim this reward has ever been made.The colour pattern is a complex geometric pattern that incorporates different colours. The back typically has a series of irregular diamond shapes flanked by smaller markings with light centers. In this species' wide geographic range, much variation of size, colour, and markings commonly occurs.
+In zoo exhibits, the colour pattern may seem garish, but in a shadowy jungle environment amid fallen leaves and debris, it allows them to virtually disappear. Called disruptive colouration, it protects them from predators and helps them to catch their prey.The huge size and attractive pattern of this snake has made it a favorite zoo exhibit, with several individuals claimed to be above 20 ft (6.1 m) in length and more than one claimed to be the largest in captivity. However, due to its huge size, immense strength, aggressive disposition, and the mobility of the skin relative to the body, it is very difficult to get exact length measurements of a living reticulated python, and weights are rarely indicative, as captive pythons are often obese. Claims made by zoos and animal parks are sometimes exaggerated, such as the claimed 14.85 m (48 ft 9 in) snake in Indonesia which was subsequently proven to be about 6.5–7 m (21 ft 4 in – 23 ft 0 in) long. For this reason, scientists do not accept the validity of length measurements unless performed on a dead or anesthetized snake that is later preserved in a museum collection or stored for scientific research.A reticulated python kept in Kansas City, Missouri, named "Medusa" is considered by the Guinness Book of World Records to be the longest living snake ever kept in captivity. In 2011 it was reported to measure 7.67 m (25 ft 2 in) and weigh 158.8 kg (350 lb 2 oz).Dwarf forms of reticulated pythons also occur, from some islands northwest of Australia, and these are being selectively bred in captivity to be much smaller, resulting in animals often referred to as "super dwarfs". Adult super dwarf reticulated pythons are typically between 1.82 and 2.4 m (6 ft 0 in and 7 ft 10 in) in length.
+
+
+== Distribution and habitat ==
+
+The reticulated python is found in South and Southeast Asia from the Nicobar Islands, India, Bangladesh, Myanmar, Thailand, Laos, Cambodia, Vietnam, Malaysia, and Singapore, east through Indonesia and the Indo-Australian Archipelago (Sumatra, the Mentawai Islands, the Natuna Islands, Borneo, Sulawesi, Java, Lombok, Sumbawa, Sumba, Flores, Timor, Maluku, Tanimbar Islands) and the Philippines (Basilan, Bohol, Cebu, Leyte, Luzon, Mindanao, Mindoro, Negros, Palawan, Panay, Polillo, Samar, Tawi-Tawi). The original description does not include a type locality. The type locality was restricted to "Java" by Brongersma (1972).Three subspecies have been proposed, but are not recognized in the Integrated Taxonomic Information System. The color and size can vary a great deal among the subspecies described. Geographical location is a good key to establishing the subspecies, as each one has a distinct geographical range.
+The reticulated python lives in rainforests, woodlands, and nearby grasslands. It is also associated with rivers and is found in areas with nearby streams and lakes. An excellent swimmer, it has even been reported far out at sea and has consequently colonized many small islands within its range. During the early years of the 20th century, it is said to have been common even in busy parts of Bangkok, sometimes eating domestic animals.
+
+
+== Behaviour and ecology ==
+
+
+=== Diet ===
+
+As with all pythons, the reticulated python is an ambush predator, usually waiting until prey wanders within strike range before seizing it in its coils and killing by constriction. Its natural diet includes mammals and occasionally birds. Small specimens up to 3–4 m (9 ft 10 in – 13 ft 1 in) long eat mainly small mammals such as rats, other rodents, mouse-eared bats, and treeshrews, whereas larger individuals switch to prey such as small Indian civet and binturong, primates, pigs, and deer weighing more than 60 kg (132 lb 4 oz). As a rule, the reticulated python seems able to swallow prey up to one-quarter its own length and up to its own weight. Near human habitation, it is known to snatch stray chickens, cats, and dogs on occasion.
+Among the largest documented prey items are a half-starved sun bear of 23 kg (50 lb 11 oz) that was eaten by a 6.95 m (22 ft 10 in) specimen and took some 10 weeks to digest.
+At least one case is reported of a foraging python entering a forest hut and taking a child.
+
+
+=== Reproduction ===
+The reticulated python is oviparous. Adult females lay between 15 and 80 eggs per clutch. At an optimum incubation temperature of 31–32 °C (88–90 °F), the eggs take an average of 88 days to hatch. Hatchlings are at least 61 cm (2 ft) in length.
+
+
+== Danger to humans ==
+
+The reticulated python is among the few snakes that prey on humans. On April 9, 2015, the species was added to the Lacey Act list in the United States, prohibiting import and interstate transport due to its "injurious" history with humans. Attacks on humans are not common, but this species has been responsible for several reported human fatalities, in both the wild and captivity. Considering the known maximum prey size, a full-grown reticulated python can open its jaws wide enough to swallow a human, but the width of the shoulders of some adult Homo sapiens can pose a problem for even a snake with sufficient size. Reports of human fatalities and human consumption (the latest examples of consumption of an adult human being well authenticated) include:
+
+A report of a visit of Antonio van Diemen, Governor-General of the Dutch East India Company, to the Banda Islands in 1638, includes a description of an enslaved woman who, when tending to a garden on the volcanic island of Gunung Api, was strangled by a snake of "24 houtvoeten" (slightly over seven meters) in length, and then swallowed whole. The snake, having become slow after ingesting such a large prey, was subsequently shot by Dutch soldiers and brought to the Governor-General to be looked at, with its victim still inside. Although the species was not named, the only snake found in Banda matching this description is the reticulated python.
+In early 20th-century Indonesia: On Salibabu island, North Sulawesi, a 14-year-old boy was killed and supposedly eaten by a specimen 5.17 m (17 ft 0 in) in length. Another incident involved a woman reputedly eaten by a "large reticulated python", but few details are known.
+In the early 1910s or in 1927, a jeweller went hunting with his friends and was apparently eaten by a 6 m (19 ft 8 in) python after he sought shelter from a rainstorm in or under a tree. Supposedly, he was swallowed feet-first, perhaps the easiest way for a snake to actually swallow a human.
+In 1932, Frank Buck wrote about a teenaged boy who was eaten by a pet 25 ft (7.6 m) reticulated python in the Philippines. According to Buck, the python escaped, and when it was found, a human child's shape was recognized inside the snake, and turned out to be the son of the snake's owner.
+Among a small group of Aeta negritos in the Philippines, six deaths by pythons were said to have been documented within a period of 40 years, plus one who died later of an infected bite.
+In September 1995, a 29-year-old rubber tapper from the southern Malaysian state of Johor was reported to have been killed by a large reticulated python. The victim had apparently been caught unaware and was squeezed to death. The snake had coiled around the lifeless body with the victim's head gripped in its jaws when it was stumbled upon by the victim's brother. The python, reported as measuring 23 ft (7.0 m) long and weighing more than 300 lb, was killed soon after by the arriving police, who shot it four times.
+In October 2008, a 25-year-old woman appeared to have been killed by a 13-foot (4.0 m) pet reticulated python. The apparent cause of death was asphyxiation. The snake was later found in the bedroom in an agitated state.
+In January 2009, a 3-year-old boy was wrapped in the coils of a 18 ft (5.5 m) pet reticulated python, turning blue. The boy's mother, who had been petsitting the python on behalf of a friend, rescued the toddler by gashing the python with a knife. The snake was later euthanized because of its wounds.
+In December 2013, a 59-year-old security guard was strangled to death while trying to capture a python near the Bali Hyatt, a luxury hotel on Indonesia's resort island. The incident happened around 3 am as the 4.5-m (15-ft) python was crossing a road near the hotel. The victim had offered to help capture the snake, which had been spotted several times before near the hotel in the Sanur, Bali, area and escaped back into nearby bushes.
+In March 2017, the body of Akbar Salubiro, a 25-year-old farmer in Central Mamuju Regency, West Sulawesi, Indonesia, was found inside the stomach of a 7 m (23 ft 0 in) reticulated python. He had been declared missing from his palm tree plantation, and the people searching for him found the python the next day with a large bulge in its stomach. They killed the python and found the whole body of the missing farmer inside. This was the first fully confirmed case of a person being eaten by a python. The process of retrieving the body from the python's stomach was documented by pictures and videos taken by witnesses.
+In June 2018, a 54-year-old Indonesian woman in Muna Island, Southeast Sulawesi, Indonesia, was killed and eaten by a 23-ft python. The woman went missing one night while working in her garden, and the next day, a search party was organized after some of her belongings were found abandoned in the garden. The python was found near the garden with a large bulge in its body. The snake was killed and carried into town, where it was cut open, revealing the woman's body completely intact. A video of the snake being gutted was posted online.
+In June 2020, a 16-year-old Indonesian boy was attacked and killed by a 7 m (23 ft 0 in) long python in Bombana Regency, Southeast Sulawesi, Indonesia. The incident took place near a waterfall at Mount Kahar in Rumbia sub-district. The victim was separated from his four friends in the woods. When he screamed, his friends came to help and found him encoiled by a large python. Villagers came to help and managed to kill the snake using a parang machete. However, the victim had already suffocated.
+In October 2022, a 52-year-old woman rubber sap tapper in Terjun Gajah village, Betara Subdistrict, West Tanjung Jabung Regency, Jambi, Indonesia, was killed and eaten by a 6 metres (19.68-ft) python. Zahara went to tap rubber sap on Sunday 23 October 2022 and did not return home after sunset. After being reported missing for a day and night a search party was organised, and in Monday morning they have discovered a large python  with bulge in its body in a jungle near the rubber plantation. The villagers immediately killed and dissected the python only to discover the body of the missing woman inside. Villagers were alarmed, fearing there might be more large python lurking in the rubber plantation, since previously two goats were reported missing by farmers.
+
+
+== In captivity ==
+
+Increased popularity of the reticulated python in the pet trade is due largely to increased efforts in captive breeding and selectively bred mutations such as the "albino" and "tiger" strains. It can make a good captive, but keepers should have previous experience with large constrictors to ensure safety to both animal and keeper. Although its interactivity and beauty draws much attention, some feel it is unpredictable. It does not attack humans by nature, but will bite and possibly constrict if it feels threatened, or mistakes a hand for food. While not venomous, large pythons can inflict serious injuries, sometimes requiring stitches.
+
+
+== In popular culture ==
+In Moonraker (1979), a reticulated python suffocates James Bond (Roger Moore), but Bond kills the snake with a hypodermic pen.

+Mauremys reevesii, commonly known as the Chinese pond turtle, the Chinese three-keeled pond turtle, or Reeves' turtle, is a species of turtle in the family Geoemydidae, a family which was formerly called Bataguridae. The species is native to East Asia.
+It is one of the two most commonly found species used for divination that have been recovered from Shang dynasty sites.
+
+
+== Geographic range ==
+Mauremys reevesii is native to China and Korea, and is thought to have been introduced to Japan and Taiwan in historic times; it was previously thought to be native to both these regions. The species is thought to have been introduced to Japan from the Korean Peninsula near the end of the 18th century. Introduced populations of M. reevesii may serve as a threat to the native turtles of these regions due to its propensity for hybridization.
+
+
+== Habitat and behaviour ==
+M. reevesii is semiaquatic, and basks in the sun on rocks or logs and can often be found leaving water to do so. They can usually be found in marshes, relatively shallow ponds, streams, and canals with muddy or sandy bottoms.
+
+
+== Conservation status ==
+The Chinese three-keeled pond turtle (M. reevesii) is threatened by competition with released pet red-eared sliders (Trachemys scripta elegans), overhunting (its plastron is used in traditional Chinese medicine), capturing for the pet trade, and wild habitat destruction. The IUCN considers M. reevesii an endangered species. This species, fortunately, breeds well in captivity.
+
+
+== Etymology ==
+The specific name, reevesii, is in honor of English naturalist John Reeves.
+
+
+== Hybridization ==
+This species, Mauremys reevesii, is notorious for its ability to produce hybrids with other Geoemydidae, even species that are only distantly related. The supposed new species "Mauremys pritchardi " was based on a hybrid of unknown origin between a male of this species and a female yellow pond turtle (Mauremys mutica). Furthermore, it has hybridized with the Chinese stripe-necked turtle (Ocadia sinensis), female Malayan box turtles (Cuora amboinensis), a male four-eyed turtle (Sacalia quadriocellata), and the Japanese pond turtle (Mauremys japonica) in captivity. This hybridization may pose a threat to the populations of native M. mutica and Chinese stripe-necked turtle (M. sinensis) in Taiwan, and the endemic M. japonica in Japan.Any individuals that are available as pets therefore need to be kept separate from other members of the family.
+
+
+== Farming ==
+High demand for turtle plastrons for Shang divination rites and archaeological findings of large caches of turtle shells has led some scholars to speculate that Mauremys reevesii may have been farmed for this purpose in antiquity.M. reevesii is one of the species raised on China's modern-day turtle farms. According to a 1998 survey, 548 farms raised this turtle species in four provinces in China.
+The statistical data from different provinces were in different formats; however, two provinces reported 20,650 turtles living on 26 farms, with 5,000 animals reproduced annually; the other two provinces reported the total weight of their turtles, namely some 260 tons of these animals on 522 farms. Over the five-year period, 1990–1995, 13 traditional Chinese medicine factories consumed 430 tons of C. reevesii plastrons.Based on a more recent (2002) survey of 684 Chinese turtle farms (less than half of all 1,499 turtle farms that were registered at the time), researchers found that 2.8 million of turtles of this species (reported there as Chinemys reevesii) lived on these farms, with some 566,000 specimens sold by farmers every year. The total weight of the annual product was 320 tons, with the estimated value of over US$6 million, which makes the market value of a Chinese pond turtle equal to around $12—about twice as much that of the most common farmed species, Pelodiscus sinensis. Taking into account the registered farms that did not respond to the survey, as well as the unregistered producers, the total amounts must be considerably higher.
+
+
+=== Pet trade ===
+Chinese pond turtles are also farmed for the pet trade. In captivity, they require similar care to red-eared sliders (T. s. elegans).
+
+
+=== East Timor ===
+During surveys in East Timor (Timor-Leste), a small but well-established population of M. reevesii was found living in marshes near the city of Dili. The species is not native to the island and was possibly introduced by locals of Chinese origin. East Timor is home to the Roti Island snake-necked turtle (Chelodina mccordi), more specifically the subspecies C. m. timorensis (sometimes considered a species of its own). Although the introduced population of M. reevesii is not known to present a risk to the native turtles per se, they could indirectly present a threat to the natives if confused. M. reevesii from the introduced population are sometimes captured to be sold to people of Chinese origin and this may cause problems if extended to the native turtles. A potential solution is to remove the introduced M. reevesii (thereby restricting the trade to captive farmed M. reevesii).

+Morelia spilota, commonly referred to as the carpet python, is a large snake of the family Pythonidae found in Australia, New Guinea (Indonesia and Papua New Guinea), Bismarck Archipelago, and the northern Solomon Islands. Many subspecies are described; ITIS lists six, the Reptile Database six, and the IUCN eight.
+
+
+== Description ==
+
+M. spilota is a large species of python in the genus, reaching between 2 and 4 m (6.6 and 13.1 ft) in length and weighing up to 15 kg (33 lb). M. s. mcdowelli is the largest subspecies, regularly attaining lengths of 2.7–3.0 m (8.9–9.8 ft). M. s. variegata is the smallest subspecies, typically 120–180 cm (3.9–5.9 ft) in length. The average adult length is roughly 2 m (6.6 ft). However, one 3-year-old captive male M. s. mcdowelli, measured in Ireland, was found to exceed 396 cm (12.99 ft). Males are typically smaller than females; in some regions, females are up to four times heavier. The head is triangular with a conspicuous row of thermoreceptive labial pits.
+The colouring of M. spilota is highly variable, ranging from olive to black with white or cream and gold markings. The patterning may be roughly diamond-shaped or have intricate markings made up of light and dark bands on a background of gray or a version of brown.
+
+
+== Reproduction ==
+The species is oviparous, with females laying 10–50 eggs at a time. Afterward, females coil around the eggs to protect them and keep them warm through using muscular contractions to generate heat. This type of maternal care, which is typical for pythons, ceases once the hatchlings have emerged.
+
+
+== Behaviour ==
+Differences in activity are noted throughout various subspecies; as a whole, the species is generally active during both daytime and nighttime, although the subspecies M. s. variegata is noted to be primarily nocturnal. Carpet pythons favor arboreal living conditions, although they can also be found on the ground, and they commonly use open spaces to bask.
+
+
+== Diet ==
+Carpet pythons kill prey by constriction. Their diet consists mainly of small mammals, birds, and lizards. Incidents of carpet pythons devouring domestic cats and small dogs have been reported.
+
+
+== Distribution and habitat ==
+The species is found throughout mainland Australia, with the exception of the arid centre and the western regions. It is widely distributed throughout the forest regions of Southwest Australia.  It is also found in Indonesia (southern Western New Guinea in Merauke Regency), Papua New Guinea (southern Western Province, the Port Moresby area of Central Province), and on Yule Island. The type locality given is "Nouvelle-Hollande" [Australia].It occurs in a wide variety of habitats, from the rainforests of northeastern Queensland (M. s. cheynei) through the River Red Gum/Riverbox woodlands of the Murray and Darling Rivers (M. s. metcalfei), to the arid, treeless islands of the Nuyts Archipelago off the South Australian west coast (M. s. imbricata). It is also found in temperate grasslands with hot and dry weather. It is often found near human habitation, where it performs a useful service by eating rats and other vermin. M. spilota is known to occur in areas that receive snowfall.
+
+
+== Conservation ==
+M. spilota is not threatened as a species. The nominate subspecies, M. s. spilota, is listed as threatened with extinction in Victoria. The subspecies M. s. imbricata is regarded as near threatened in Western Australia, due to loss of habitat.
+
+
+== Captivity ==
+This species is a popular pet among snake enthusiasts. Some forms can be more irascible than others, such as M. s. mcdowelli and M. s. variegata. Forms that tend to be more even tempered include M. s. spilota and M. s. metcalfei.  Although they can be nippy as hatchlings, most grow into docile adults. However, care must be taken when feeding, as these snakes have a strong "feeding response" that can be mistaken for aggression.
+The care requirements can be generalized for all subspecies. The subspecies M. s. spilota, the cold-weather diamond python, has some separate requirements and habits. As medium to large snakes, carpet pythons need a proportionately sized enclosure that allows for climbing as well as crawling around on the ground. They generally require moderately high basking temperature and moderate humidity. Captive specimens are normally fed live or frozen (defrosted to room temperature) rats or mice, but it is considered best practice to offer a varied diet which includes other types of rodents and birds to create more balanced nutrition. Young carpet pythons can be fed every 1–2 weeks, but adults have slower metabolisms and should be fed every 2–4 weeks depending on body condition.With good care, the carpet python is capable of living up to 30 years.
+
+
+== Subspecies ==
+The geographic distribution and common names can be summarised as the following, although M. s. imbricata is missing:

+
+
+== Naming and taxonomy ==
+The first description of M. spilota was by Lacépède (1804), who placed it in the genus Coluber as Coluber spilotus. The species has since been described by various authors as containing a number of subspecies and hybrids; these have also been known by various informal names. The attempted arrangement of taxa in this, and other, Australasian Pythonidae has produced numerous synonyms. The discreet and roaming habits of this species have produced a low number of recorded specimens, giving inadequate sample numbers to support descriptions of a taxon's morphology. This is the case with proposed names which are sometimes cited, such as the Papuan Morelia spilota harrisoni (Hoser), despite being unaccepted or invalid. Common names are regional variants of carpet and diamond python or snake.The following is an incomplete list of synonyms:

+Reeves's muntjac (Muntiacus reevesi; Chinese: 山羌), also known as the Chinese muntjac, is a muntjac species found widely in southeastern China (from Gansu to Yunnan) and Taiwan. It has also been introduced in Europe, western United States and Japan. It takes its name from John Reeves, a naturalist employed by the British East India Company in the 19th century.
+
+
+== Description ==
+Reeves's muntjac grows to 0.5 m (1 ft 8 in) high at the shoulder and 0.95 m (3 ft 1 in) in length, plus a short tail up to 4 in (10 cm) long. It weighs between 10 and 18 kg (22 and 40 lb) when fully grown. It is reddish-brown in appearance with striped markings on its face. The belly is creamy-white, with lighter fur extending to the neck, chin, and the underside of the tail. The males have short antlers, usually 4 in (10 cm) or less, and long upper canines (tusks), usually about 2 in (5.1 cm) long. Females have bony lumps on their foreheads and localized black spots. The Taiwanese subspecies (M. r. micrurus), commonly known as the Formosan Reeves's muntjac, is darker than other subspecies.
+
+
+== Behavior ==
+Reeves's muntjac feeds on herbs, blossoms, succulent shoots, fungi, berries, grasses, and nuts, and has also been reported to eat tree bark. Eggs and carrion are eaten opportunistically. It is also called the barking deer due to its distinctive barking sound, though this name is also used for other species of muntjacs. The barking sound is common during mating or when provoked. Its preferred habitats are forest and shrubland. It is a solitary and crepuscular animal. Both males and females defend small territories that they mark with preorbital gland secretions that are thought to be pheromonal in nature. When fighting, males first use their antlers to push enemies off balance so they can wound them with their 2 in (5.1 cm)  upper canine teeth.
+
+
+== Reproduction ==
+
+Female muntjacs (known as "does") become sexually mature within the first year of life. Mating occurs throughout the year. Their gestation period lasts from 209 to 220 days. Females limit the number of mating bouts, though time between successive bouts is determined by males (known as "bucks").
+
+
+== Distribution ==
+It is found widely in southeastern China (from Gansu to Yunnan) and Taiwan. It has also been introduced in several other regions.
+
+
+=== Continental Europe ===
+It has been introduced in Belgium and the Netherlands.In Europe, this species is included since 2016 in the list of Invasive Alien Species of Union concern (the Union list). This implies that this species cannot be imported, bred, transported, commercialized, or intentionally released into the environment in the whole of the European Union.
+
+
+=== Great Britain ===
+Reeves's muntjacs were first introduced to the UK in the early 19th century.In the late 19th century, the then Duke of Bedford brought some to Woburn Abbey in Bedfordshire, then in 1901 released them into the surrounding woods.: 96  A few more probably escaped from the nearby Whipsnade Zoo. During the mid-20th century, Woburn conducted several deliberate releases in distant locations throughout England.: 97  It is suspected that there were also other unrecorded releases or escapes from private collections. These releases later caused misperception that muntjacs spread very rapidly.: 98  The estimated population of Reeves's muntjacs in England was 52,000 in 1995, and 104,000 in 2008.: 100 Under the Wildlife and Countryside Act 1981 it was illegal to release the species except where already established, and the Invasive Alien Species (Enforcement and Permitting) Order 2019 has subsequently prohibited the capture and re-release of muntjac in all cases. As of 2017, colonies exist throughout England south of Derbyshire, and the population continues to grow.
+
+
+=== Ireland ===
+It has been introduced in the Republic of Ireland.Sightings in 2008 caused the government, concerned at the risk of the species becoming established, to quickly introduce a year-round hunting season.
+
+
+=== Japanese archipelago ===
+In the 1960s, several specimens escaped from an exhibition zoo in the Bōsō Peninsula in eastern Japan. By 2017, their numbers had reached at least 60,000. It is considered a harmful invasive species and has inflicted severe damage to ashitaba plantations. Also, Reeves's muntjac escaped a zoo on Izu Ōshima in 1970 when a fence fell due to a typhoon. A muntjac eradication effort on Izu Ōshima was undertaken in 2007–2014 but failed, and as of 2014, at least 11,000 individuals exist and have a yearly population growth rate of 15%. This failure has been blamed on inadequate survey methods.
+
+
+== Conservation ==
+In Hong Kong, Reeve's muntjac is a protected species under the Wild Animals Protection Ordinance Cap 170. It is listed as least concern by the IUCN due to being generally common and widespread.
+
+
+== Economic significance ==
+The tanned skin of Reeves's muntjac is notable for its softness and is occasionally used in beauty-care products, musical instruments, lenses, and antique items packaging. Low-fat muntjac meat is also noted for its culinary qualities.

+The violet turaco, also known as the violaceous plantain eater (Musophaga violacea), is a large turaco, a group of African otidimorphae.
+
+
+== Characteristics ==
+These are unmistakable birds, but shy and often inconspicuous in the treetops. They are approximately 48 cm (19 in) long, including a long tail and a 4 cm (1.6 in) bill. They boast a winglength of 21 cm (8.3 in) and weigh approximately 360 g. The plumage is glossy violet, except for the yellow forehead, chestnut crown and white ear coverts; the bill is thick and red. In flight, the violet turaco's crimson primary flight feathers contrast with the violet plumage. The red colour in the wings is typical of turacos.
+
+
+== Habitat ==
+It is resident in West Africa, and has an extremely large range from Senegal through to the Nigeria, with an isolated population in Chad and Central African Republic. It occurs in tropical savannas, wetlands, woodlands and forests.
+
+
+== Diet ==
+Diet consists of fruit, and they are quite partial to figs, but they will also eat leaves, buds, flowers, insects, snails and slugs.
+
+
+== Reproduction ==
+Cooperative breeding behavior has been observed in captivity in this species. The female lays two eggs in a flimsy tree platform nest.
+
+
+== Threats ==
+This species is locally common, but is vulnerable to trapping for the pet trade in Guinea, Sierra Leone, Liberia and Ghana.
+
+
+== Behavior ==
+Turacos are social birds, travelling in flocks of around ten to twelve individuals. They are not strong fliers but they can run quickly through the branches. Violet turaco has a loud cooroo-cooroo call.

+The giant anteater (Myrmecophaga tridactyla) is an insectivorous mammal native to Central and South America. It is one of four living species of anteaters, of which it is the largest member. The only extant member of the genus Myrmecophaga, it is classified with sloths in the order Pilosa. This species is mostly terrestrial, in contrast to other living anteaters and sloths, which are arboreal or semiarboreal. The giant anteater is 182 to 217 cm (5 ft 11+1⁄2 in to 7 ft 1+1⁄2 in) in length, with weights of 33 to 50 kg (73 to 110 lb) for males and 27 to 47 kg (60 to 104 lb) for females. It is recognizable by its elongated snout, bushy tail, long fore claws, and distinctively colored pelage.
+The giant anteater is found in multiple habitats, including grassland and rainforest. It forages in open areas and rests in more forested habitats. It feeds primarily on ants and termites, using its fore claws to dig them up and its long, sticky tongue to collect them. Though giant anteaters live in overlapping home ranges, they are mostly solitary except during mother-offspring relationships, aggressive interactions between males, and when mating. Mother anteaters carry their offspring on their backs until weaning them.
+The giant anteater is listed as vulnerable by the International Union for Conservation of Nature. It has been extirpated from many parts of its former range. Threats to its survival include habitat destruction, fire, and poaching for fur and bushmeat, although some anteaters inhabit protected areas.  With its distinctive appearance and habits, the anteater has been featured in pre-Columbian myths and folktales, as well as modern popular culture.
+
+
+== Taxonomy and phylogeny ==
+The giant anteater got its binomial name from Carl Linnaeus in 1758. Its generic name, Myrmecophaga, and specific name, tridactyla, are both Greek, meaning "anteater" and "three fingers", respectively. Myrmecophaga jubata was used as a synonym. Three subspecies have been tentatively proposed: M. t. tridactyla (ranging from Venezuela and the Guianas to northern Argentina), M. t. centralis (native to Central America, northwestern Colombia, and northern Ecuador), and M. t. artata (native to northeastern Colombia and northwestern Venezuela). The giant anteater is grouped with the semiarboreal northern and southern tamanduas in the family Myrmecophagidae. Together with the family Cyclopedidae, whose only extant member is the arboreal silky anteater, the two families comprise the suborder Vermilingua.
+Anteaters and sloths belong to order Pilosa and share superorder Xenarthra with the Cingulata (whose only extant members are armadillos). The two orders of Xenarthra split 66 million years ago (Mya) during the Late Cretaceous epoch. Anteaters and sloths diverged around 55 Mya, between the Paleocene and Eocene epochs. The Cyclopes lineage emerged around 30 Mya in the Oligocene epoch, while the Myrmecophaga and Tamandua lineages split 10 Mya in the Late Miocene subepoch. During most of the Cenozoic era, anteaters were confined to South America, which was formerly an island continent. Following the formation of the Isthmus of Panama about 3 Mya, anteaters of all three extant genera invaded Central America as part of the Great American Interchange.The fossil record for anteaters is generally sparse. Known fossils include the Pliocene genus Palaeomyrmidon, a close relative to the silky anteater, Protamandua, the sister taxon to the clade that includes the giant anteater and the tamanduas from the Miocene, and Neotamandua, a sister taxon to Myrmecophaga. Protamandua was larger than the silky anteater, but smaller than a tamandua, while Neotamandua was larger, falling somewhere between a tamandua and a giant anteater. Protamandua did not appear to have feet specialized for terrestrial or arboreal locomotion, but it may have had a prehensile tail. Neotamandua, though, is unlikely to have had a prehensile tail and its feet were intermediate in form between those of the tamanduas and the giant anteater. The species Neotamandua borealis was suggested to be an ancestor of the latter. Another member of the genus Myrmecophaga has been recovered from the Montehermosan Monte Hermoso Formation in Argentina and was described by Kraglievitch in 1934 as Nunezia caroloameghinoi. The species was reclassified as Myrmecophaga caroloameghinoi by S. E. Hirschfeld in 1976.The giant anteater is the most terrestrial of the living anteater species. Its ancestors may originally have been adapted to arboreal life; the transition to life on the ground could have been aided by the expansion of open habitats such as savanna in South America and the availability there of colonial insects, such as termites, that provided a larger potential food source. Both the giant anteater and the southern tamandua are well represented in the fossil record of the late Pleistocene and early Holocene.
+
+
+== Characteristics and adaptations ==
+
+The giant anteater can be identified by its large size, elongated muzzle, and long bushy tail. It has a total body length of 182 to 217 cm (5 ft 11+1⁄2 in to 7 ft 1+1⁄2 in). Males weigh 33 to 50 kg (73 to 110 lb) and females weigh 27 to 47 kg (60 to 104 lb), making the giant anteater the biggest extant species in its suborder. The head of the giant anteater, at 30 cm (12 in) long, is particularly elongated, even when compared to other anteaters. Its tubular snout, which ends in its tiny mouth opening and nostrils, takes up most of its head. Its eyes and ears are relatively small. It has poor eyesight, but its sense of smell is 40 times more sensitive than that of humans.Even for an anteater, the neck is especially thick compared to the back of the head, and a small hump is found at the back of the neck. The coat is mostly greyish, brown or black and salted with white. The forelimbs are white, with black bands around the wrists, while the hindlimbs are dark. Thick black bands with white outlines stretch from throat to shoulder, ending in triangular points. The body ends in a brown tail. The coat hairs are long, especially on the tail, which makes the tail look larger than it actually is. A stiff mane stretches along the back. The bold pattern was thought to be disruptive camouflage, but a 2009 study suggests it is warning coloration. While adult males are slightly larger and more muscular than females, with wider heads and necks, visual sex determination can be difficult. The penis and testes are located internally between the rectum and urinary bladder in males, and females have a single pair of mammary glands near the armpits.The giant anteater has broad ribs. Despite its specific name, tridactyla, meaning three fingers, it has five toes on each foot. Four toes on the front feet have claws, which are particularly elongated on the second and third digits. It walks on its front knuckles similar to gorillas and chimpanzees. Doing this allows the giant anteater to keep its claws out of the way while walking. The middle digits, which support most of its weight, are extended at the metacarpophalangeal joints and bent at the interphalangeal joints. Unlike the front feet, the hind feet have short claws on all five toes and walk plantigrade. As a "hook-and-pull" digger, the giant anteater's enlarged supraspinous fossa gives the teres major more leverage—increasing the front limbs' pulling power—and the triceps muscle helps power the flexion of the thickened third digit of the front feet.The giant anteater has a low body temperature for a mammal, about 33 °C (91 °F), a few degrees lower than a typical mammalian temperature of 36 to 38 °C (97 to 100 °F). Xenarthrans in general tend to have lower metabolic rates than most other mammals, a trend thought to correlate with their dietary specializations and low mobility.
+
+
+=== Feeding anatomy ===
+
+The giant anteater has no teeth and is capable of only very limited jaw movement. It relies on the rotation of the two halves of its lower jaw, held together by a ligament at the tip, to open and close its mouth. This is accomplished by its chewing muscles, which are relatively underdeveloped. Jaw depression creates an oral opening large enough for the slender tongue to flick out. It is typically 60 cm (24 in) long and is triangular posteriorly, rounded anteriorly, and ends in a small, rounded tip. The tongue is covered in backward-curving papillae and coated in thick, sticky saliva secreted from its enlarged salivary glands.The tube-like rostrum and small mouth opening restrict the tongue to protrusion-retraction movements. During feeding, the animal relies on the orientation of its head for aim. The tongue can reach up to 45 cm (18 in), longer than the length of the skull, and move in and out around 160 times per minute (nearly three times per second). The anteater's tongue has little to no attachments to the hyoid and this is what allows it to flick its tongue at such distances and speed. The long sternoglossus muscle, which is formed by the fusion of the sternohyoid and the hyoglossus, is directly anchored to the sternum. The hyoid apparatus is large, V-shaped and flexible and supports the tongue as it goes in and out of the mouth. The buccinators allow it to slide back in without losing attached food and tighten the mouth to prevent food from escaping as it extends. When retracted, the tongue is held in the oropharynx by the secondary palate, preventing it from blocking respiration.Giant anteaters swallow at a much higher rate than most other mammals; when feeding, they swallow almost continuously. Before being swallowed, insects are crushed against the palate. The giant anteater's stomach, similar to a bird's gizzard, has hardened folds and uses strong contractions to grind up the insects. The digestive process is assisted by small amounts of ingested sand and soil. The giant anteater cannot produce stomach acid of its own, but uses the formic acid of its prey for digestion.
+
+
+== Distribution and status ==
+
+The giant anteater is native to Central and South America. Its known range stretches from Honduras to the Gran Chaco region, and fossil remains have been found as far north as northwestern Sonora, Mexico. It is largely absent from the Andes and has been fully extirpated in Uruguay, Belize, El Salvador, and Guatemala, as well as in parts of Costa Rica, Brazil, Argentina, and Paraguay. The species is found in a number of habitats including both tropical rainforest and xeric shrubland, provided enough prey is present to sustain it.The species is listed as vulnerable by the International Union for Conservation of Nature, due to the number of regional extirpations, and under Appendix II by CITES, tightly restricting international trade in specimens of the animal and its parts and derivatives. Between 2000 and 2010, the total population declined by 30%. In 1994, some 340 giant anteaters died due to wildfires at Emas National Park in Brazil. The animal is particularly vulnerable to fires due to its slow movement and flammable coat.Human-induced threats include collision with vehicles, attacks by dogs, and destruction of habitat. One study of anteater mortality along roads found that they are likely to become roadkill on straight roads with native vegetation along the side. A 2018 study in Brazil found that: (1) fragmentation of habitat could be more detrimental than road mortality, (2) 18–21% of suitable anteater habitat was below minimum patch size, (3) 0.1–1% of its distribution was maximum road density, (4) 32–36% of the anteater's range represented critical areas for its survival and (5) more conservation opportunities existed in the north of the country. A 2020 study in the Brazilian Cerrado found that road morality can decrease the local population growth by half.The giant anteater is commonly hunted in Bolivia, both for sport and sustenance. The animal's thick, leathery hide is used to make equestrian equipment in the Chaco. In Venezuela, it is hunted for its claws. Giant anteaters are killed for safety reasons, due to their reputation as dangerous animals. The giant anteater remains widespread. Some populations are stable and the animal is found in various protected areas in the Amazon, Pantanal and the Cerrado. It is officially protected in some Argentine provinces as a national heritage species.
+
+
+== Behavior and ecology ==
+
+The giant anteater may use multiple habitats. A 2007 study of giant anteaters in the Brazilian Pantanal found the animals generally forage in open areas and rest in forested areas, possibly because forests are warmer than grasslands on cold days and cooler on hot days. Anteater may travel an average of 3,700 m (12,100 ft) per day. Giant anteaters can be either diurnal or nocturnal. A 2006 study in the Pantanal found those anteaters to be mostly nocturnal: they are most active during nighttime and early morning, and retire as the temperature rises. On colder days, they start and end periods of activity earlier, shifting them into daylight hours, and may become diurnal. Diurnal giant anteaters have been observed at Serra da Canastra. Nocturnality in anteaters may be a response to human disturbances.Giant anteaters typically rest in dense brush, but may use tall grass on cooler days. They carve a shallow cavity in the ground for resting. The animal sleeps curled up with its bushy tail folded over its body. The tail serves both to conserve body heat and as camouflage. One anteater was recorded sleeping with its tail stretched out on a sunny morning with an ambient temperature of 17 °C (63 °F); possibly it was positioned this way to allow its body to absorb the sun's rays for warmth.Giant anteaters are good swimmers and are capable of moving through wide rivers. They have been observed to bathe. They are also able to climb and have been recorded ascending both termite mounds and trees while foraging. One individual was observed holding onto a branch with its feet just touching the ground.
+
+
+=== Spacing ===
+
+Giant anteaters' home ranges vary in size depending on the location, ranging from as small as 2.7 km2 (667 acres) in Serra da Canastra National Park, Brazil, to as large as 32.5 km2 (8,031 acres) in Iberá Natural Reserve, Argentina. Individuals mostly live alone, except for females that nurse their young and males courting females. Anteaters communicate their presence, status, and sexual condition with secretions from their anal glands. They also advertise their presence to other individuals though tree markings and urine. They appear to be able to recognize each other's saliva by scent.Females appear to be more tolerant of females than males are of males, leading to greater overlap in female home ranges. Males are more likely to engage in agonistic behaviors, such as slowly circling each other, chasing, or actual fighting. Circling anteaters may utter a drawn-out "harrr" noise. In combat, they slash at each other with their claws and wrestle each other to the ground. Fighting anteaters may emit roars or bellows. Males are possibly territorial.
+
+
+=== Foraging ===
+
+This animal is an insectivore, feeding mostly on ants or termites. In areas that experience seasonal flooding, like the grassy plains of the Venezuelan-Colombian Llanos, anteaters mainly feed on ants, because termites are less available. Conversely, anteaters at Emas National Park eat mainly termites, which occur in high density on the grasslands. At Serra da Canastra, anteaters switch between eating mainly ants during the wet season (October to March) and termites during the dry season (May to September).Anteaters track prey by their scent. After finding a nest, the animal tears it open with its long fore claws and inserts its long, sticky tongue to collect its prey. An anteater spends one minute on average feeding at a nest, visiting up to 200 nests in one day and consuming as many as 30,000 insects. The anteater may be driven away from a nest by the chemical or biting attacks of soldiers. Some termite species rely on their fortified mounds for protection and many individuals escape while the predator digs. These modes of defense prevent the entire colony from being eaten in one anteater attack.Other prey include the larvae of beetles and western honey bees that have located their hives in termite mounds. Anteaters may target termite mounds with bee hives. In captivity, anteaters are fed mixtures made of milk, eggs, mealworms, and ground beef. To drink, an anteater may dig for water when no surface water is available, creating waterholes for other animals.
+
+
+=== Reproduction and parenting ===
+
+Giant anteaters can mate throughout the year. During courtship, a male consorts with an estrous female, following and sniffing her. Male and female pairs are known to feed at the same insect nest. While mating, the female lies on her side as the male crouches over her. A couple may stay together for up to three days and mate several times during that period. Gestation lasts around 190 days and ends with the birth of a single pup, which typically weighs around 1.4 kg (3 lb). Females give birth standing upright.Pups are born with eyes closed and begin to open them after six days. The mother carries its dependent pup on its back. The pup's black and white band aligns with its mother's, camouflaging it. The young communicate with their mothers with sharp whistles and use their tongues during nursing. After three months, the pup begins to eat solid food and is fully weaned by ten months. The mother grooms her offspring during rest periods lasting up to an hour. Grooming peaks during the first three months and declines as the young reaches nine months of age, ending by ten months. The decline mirrors that of the weakening bond between mother and offspring; young anteaters usually become independent by nine or ten months. Anteaters are sexually mature in 2.5–4 years.
+
+
+=== Mortality ===
+Giant anteaters can live around 16 years in captivity. They are primarily prey for jaguars and pumas and typically flee from danger by galloping, but if cornered, will rear up on their hind legs and slash at the attacker. The front claws of the giant anteater are formidable weapons, capable of killing a jaguar. The giant anteater is a host of the Acanthocephalan intestinal parasites Gigantorhynchus echinodiscus and Moniliformis monoechinus.
+
+
+== Interactions with humans ==
+
+
+=== Attacks ===
+Although they are shy and typically attempt to avoid humans, giant anteaters can inflict severe wounds with their front claws and have been known to seriously injure or kill humans who corner and threaten them. Between 2010 and 2012, two hunters were killed by giant anteaters in Brazil; in both cases, the hunters were agitating and wounding cornered animals and the attacks appeared to be defensive behaviors. In April 2007, an anteater at the Florencio Varela Zoo mauled and killed a zookeeper with its front claws. The animal in question, a male named Ramon, had a reputation for aggressiveness.
+
+
+=== In culture ===
+
+In the mythology and folklore of the indigenous peoples of the Amazon Basin, the giant anteater is depicted as a trickster foil to the jaguar, as well as a humorous figure due to its long snout. In one Shipib tale, an anteater challenged a jaguar to a breath-holding contest under water, which the jaguar accepted. After the two removed their pelts and submerged, the anteater jumped out of the water and stole the jaguar's pelt, leaving the jaguar with the anteater's pelt. In a Yarabara myth, the evil ogre Ucara is transformed into one by the sun. This myth emphasizes the nearly immobile nature of the anteater's mouth, which was considered a burden. The Kayapo people wear masks of various animals and spirits, including the anteater, during naming and initiation ceremonies. They believe women who touched anteater masks or men who stumbled while wearing them would die or receive some sort of physical disorder.During the Spanish colonization of the Americas, the giant anteater was one of many native fauna taken to Europe for display. At first, Europeans believed all anteaters were female and mated with their noses, a misconception corrected by naturalist Félix de Azara. In the 20th century, Salvador Dalí wrote imaginatively that the giant anteater "reaches sizes bigger than the horse, possesses enormous ferocity, has exceptional muscle power, is a terrifying animal." Dalí depicted an anteater in the style of The Great Masturbator. It was used as a bookplate for André Breton, who compared the temptations a man experiences in life to what "the tongue of the anteater must offer to the ant."The 1940 Max Fleischer cartoon Ants in the Plants features a colony of ants fighting off a villainous anteater. Released during the Phoney War, the film may have alluded to France's Maginot Line. An anteater is also a recurring character in the comic strip B.C. This character was the inspiration for Peter the Anteater, the University of California, Irvine team mascot. In the Stephen King miniseries Kingdom Hospital, the character Antubis appears in the form of an anteater-like creature with razor-sharp teeth.

+The clouded leopard (Neofelis nebulosa), also called the mainland clouded leopard, is a wild cat inhabiting dense forests from the foothills of the Himalayas through mainland Southeast Asia into South China. In the early 19th century, a clouded leopard was brought to London from China and described in 1821. It has large dusky-grey blotches and irregular spots and stripes reminiscent of clouds. Its head-and-body length ranges from 68.6 to 108 cm (27.0 to 42.5 in) with a 61 to 91 cm (24 to 36 in) long tail. It uses its tail for balancing when moving in trees and is able to climb down vertical tree trunks head first. It rests in trees during the day and hunts by night on the forest floor.
+The clouded leopard is the first cat that genetically diverged 9.32 to 4.47 million years ago from the common ancestor of the pantherine cats. Today, the clouded leopard is locally extinct in Singapore, Taiwan, and possibly Hainan Island and Vietnam. Its total population is suspected to be fewer than 10,000 mature individuals, with a decreasing population trend, and no single population numbering more than 1,000 adults. It has therefore been listed as Vulnerable on the IUCN Red List since 2008. The population is threatened by large–scale deforestation and commercial poaching for the wildlife trade. Its body parts are offered for decoration and clothing, though it is legally protected in most range countries.
+The clouded leopard has been kept in zoological gardens since the early 20th century. Captive breeding programs were initiated in the 1980s. In captivity, the clouded leopard has an average lifespan of 11 years.
+
+
+== Taxonomy and phylogeny ==
+Felis nebulosa was proposed by Edward Griffith in 1821 who first described a skin of a clouded leopard that was brought alive from Canton Province in China to the menagerie at Exeter Exchange in London.Felis macrosceloides proposed by Brian Houghton Hodgson in 1841 was a clouded leopard specimen from Nepal.Felis brachyura proposed by Robert Swinhoe in 1862 was a clouded leopard skin from Taiwan.
+The generic name Neofelis was proposed by John Edward Gray in 1867 who subordinated all three to this genus.
+At present, N. nebulosa is considered a monotypic species due to lack of evidence for subspeciation.Felis diardi proposed by Georges Cuvier in 1823 was based on a clouded leopard skin from Java.
+It was considered a clouded leopard subspecies by Reginald Innes Pocock in 1917. In 2006, it was identified as a distinct Neofelis species, the Sunda clouded leopard. Populations in Taiwan and Hainan Island are considered to belong to the mainland clouded leopard.
+
+
+=== Phylogeny ===
+Skulls of clouded leopard and Panthera species were analysed morphologically in the 1960s. Results indicate that the clouded leopard forms an evolutionary link between the Pantherinae and the Felinae.Phylogenetic analysis of the nuclear DNA in tissue samples from all Felidae species revealed that the evolutionary radiation of the Felidae began in the Miocene around 14.45 to 8.38 million years ago in Asia. Analysis of mitochondrial DNA of all Felidae species indicates a radiation at 16.76 to 6.46 million years ago.
+The clouded leopard is estimated to have been the first cat that genetically diverged from the common ancestor of the Felidae 9.32 to 4.47 million years ago, based on analysis of their nuclear DNA.
+The clouded leopard from mainland Asia reached Borneo and Sumatra via a now submerged land bridge probably during the Pleistocene, when populations became isolated during periods of global cooling and warming. Genetic analysis of hair samples of the clouded leopard and its sister species the Sunda clouded leopard (N. diardi) indicates that they diverged 2.0–0.93 million years ago.
+
+
+== Characteristics ==
+
+The clouded leopard's fur is of a dark grey or ochreous ground-color, often largely obliterated by black and dark dusky-grey blotched pattern. There are black spots on the head, and the ears are black. Partly fused or broken-up stripes run from the corner of the eyes over the cheek, from the corner of the mouth to the neck, and along the nape to the shoulders. Elongated blotches continue down the spine and form a single median stripe on the loins. Two large blotches of dark dusky-grey hair on the side of the shoulders are each emphasized posteriorly by a dark stripe, which passes on to the foreleg and breaks up into irregular spots. The flanks are marked by dark dusky-grey irregular blotches bordered behind by long, oblique, irregularly curved or looped stripes. These blotches yielding the clouded pattern suggest the English name of the cat. The underparts and legs are spotted, and the tail is marked by large, irregular, paired spots. Its legs are short and stout, and paws broad. Females are slightly smaller than males.Its hyoid bone is ossified, making it possible to purr. Its pupils contract into vertical slits. Irises are brownish yellow to grayish green. Melanistic clouded leopards are uncommon. It has rather short limbs compared to the other big cats. Its hind limbs are longer than its front limbs to allow for increased jumping and leaping capabilities. Its ulnae and radii are not fused, which also contributes to a greater range of motion when climbing trees and stalking prey. Clouded leopards weigh between 11.5 and 23 kg (25 and 51 lb). Females vary in head-to-body length from 68.6 to 94 cm (27.0 to 37.0 in), with a tail 61 to 82 cm (24 to 32 in) long. Males are larger at 81 to 108 cm (32 to 43 in) with a tail 74 to 91 cm (29 to 36 in) long. 
+Its shoulder height varies from 50 to 55 cm (20 to 22 in).Its skull is long and low with strong occipital and sagittal crests. The canine teeth are exceptionally long, the upper being about three times as long as the basal width of the socket. The first premolar is usually absent. The upper pair of canines measure 4 cm (1.6 in) or longer.
+It has a bite force at the canine tip of 544.3 Newton and a bite force quotient at the canine tip of 122.4.
+The clouded leopard is often referred to as a "modern-day sabre-tooth" because it has the largest canines in proportion to its body size.
+
+
+== Distribution and habitat ==
+
+The clouded leopard occurs from the Himalayan foothills in Nepal, Bhutan and India to Myanmar, southeastern Bangladesh, Thailand, Peninsular Malaysia, to south of the Yangtze River in China. It is regionally extinct in Singapore and Taiwan.In Nepal, the clouded leopard was thought to be extinct since the late 1860s. But in 1987 and 1988, four individuals were found in the central part of the country, close to Chitwan National Park and in Pokhara Valley. These findings extended the known range westward, suggesting it is able to survive and breed in degraded woodlands that previously harboured moist subtropical semideciduous forest. Since then, the clouded leopard has been recorded in Shivapuri Nagarjun National Park and in Annapurna Conservation Area. Between 2014 and 2015, it was also recorded in Langtang National Park at an elevation range of 1,823–3,498 m (5,981–11,476 ft).In India, it occurs in Sikkim, northern West Bengal, Meghalaya subtropical forests, Tripura, Mizoram, Manipur, Assam, Nagaland and Arunachal Pradesh. In Pakke Tiger Reserve, a clouded leopard was photographed in semi-evergreen forest at an elevation of 144 m (472 ft). In Sikkim, clouded leopards were photographed by camera traps at elevations of 2,500–3,720 m (8,200–12,200 ft) between April 2008 and May 2010 in the Khangchendzonga Biosphere Reserve. In Manas National Park, 16 individuals were recorded during a survey in November 2010 to February 2011. Between January 2013 and March 2018, clouded leopards were also recorded in Dampa Tiger Reserve, Eaglenest Wildlife Sanctuary and Singchung-Bugun Village Community Reserve, in Meghalaya's Nongkhyllem National Park and Balpakram-Baghmara landscape.In Bhutan, it was recorded in Royal Manas National Park, Jigme Singye Wangchuck National Park, Phibsoo Wildlife Sanctuary, Jigme Dorji National Park, Phrumsengla National Park, Bumdeling Wildlife Sanctuary and several non-protected areas. In Bangladesh, it was recorded in Sangu Matamuhari in the Chittagong Hill Tracts in 2016. In Myanmar, it was recorded by camera traps for the first time in the hill forests of Karen State in 2015.In Thailand, it inhabits relatively open, dry tropical forest in Huai Kha Khaeng Wildlife Sanctuary and closed-forest habitats in Khao Yai National Park. In Laos, it was recorded in Nam Et-Phou Louey National Protected Area in dry evergreen and semi-evergreen forests. In Cambodia, it was recorded in deciduous dipterocarp forest in Phnom Prich Wildlife Sanctuary between 2008 and 2009, and in Central Cardamom Mountains National Park, Southern Cardamom National Park, Botum Sakor National Park and Phnom Samkos Wildlife Sanctuary between 2012 and 2016. In Peninsular Malaysia, it was recorded in Taman Negara National Park, Ulu Muda Forest, Pasoh Forest Reserve, Royal Belum State Park, Temengor Forest Reserve and in a few linkages between 2009 and 2015.The last confirmed record of a Formosan clouded leopard dates to 1989, when the skin of a young individual was found in the Taroko area. It was not recorded during an extensive camera trapping survey conducted from 1997 to 2012 in more than 1,450 sites inside and outside Taiwanese protected areas.
+
+
+== Behaviour and ecology ==
+
+The clouded leopard is a solitary cat. Early accounts depict it as a rare, secretive, arboreal, and nocturnal inhabitant of dense primary forest.It is one of the most talented climbers among the cats. Captive clouded leopards have been observed to climb down vertical tree trunks head first, and hang on to branches with their hind paws bent around branchings of tree limbs. They are capable of supination and can even hang down from branches only by bending their hind paws and their tail around them. When jumping down, they keep hanging on to a branch this way until the last moment. They can climb on horizontal branches with their back to the ground, and in this position make short jumps forward. When balancing on thin branches, they use their long tails to steer. They can easily jump up to 1.2 m (3 ft 11 in) high.
+They use trees as daytime rest sites, but also spend time on the ground when hunting at night. Captive clouded leopards have been observed to scent mark by spraying urine and rubbing their heads on prominent objects.
+Their vocalisations include a short high-pitched meow call, a loud crying call, both emitted when a cat is trying to locate another one over a long or short distance; they prusten and raise their muzzle when meeting each other in a friendly manner; when aggressive, they growl with a low-pitched sound and hiss with exposed teeth and wrinkled nose.Radio-collared clouded leopards were foremost active by night but also showed crepuscular activity peaks.
+Clouded leopards recorded in northeast India were most active in the late evening after sunset.Home ranges have only been estimated in Thailand:
+
+Four individuals were radio-collared in Phu Khieo Wildlife Sanctuary from April 2000 to February 2003. Home ranges of two females were 25.7 km2 (9.9 sq mi) and 22.9 km2 (8.8 sq mi), and of two males 29.7 km2 (11.5 sq mi) and 49.1 km2 (19.0 sq mi).
+Two individuals were radio-collared during a study from 1997 to 1999 in the Khao Yai National Park. The home range of one female was 39.4 km2 (15.2 sq mi), of the one male 42 km2 (16 sq mi). Both individuals had a core area of 2.9 km2 (1.1 sq mi).In 2016, clouded leopards were detected in the forest complex of Khlong Saeng Wildlife Sanctuary and Khao Sok National Park during camera trapping surveys; 15 individuals were identified in a core zone of 200 km2 (77 sq mi) with population density estimated at 5.06 individuals per 100 km2 (39 sq mi); but only 12 individuals were identified in an edge zone of 297 km2 (115 sq mi), which is more disturbed by humans, with density estimated at 3.13 individuals per 100 km2 (39 sq mi).
+
+
+=== Hunting and diet ===
+When hunting, the clouded leopard stalks its prey or waits for the prey to approach. After making and feeding on a kill, it usually retreats into trees to digest and rest. Its prey includes both arboreal and terrestrial vertebrates.
+Pocock presumed that it is adapted for preying upon herbivorous mammals of considerable bulk because of its powerful build, long canines and the deep penetration of its bites. In Thailand, clouded leopards have been observed preying on southern pig-tailed macaque (Macaca nemestrina), Indian hog deer (Hyelaphus porcinus), Bengal slow loris (Nycticebus bengalensis), Asiatic brush-tailed porcupine (Atherurus macrourus), Malayan pangolin (Manis javanica) and Berdmore's ground squirrel (Menetes berdmorei). Known prey species in China include barking deer (Muntiacus) and pheasants.
+In northern Peninsular Malaysia, a male clouded leopard was photographed while carrying a binturong (Arctictis binturong) in its jaws.
+
+
+=== Reproduction and life cycle ===
+
+Both males and females average 26 months at first reproduction. The female is in estrus for about six days, with her estrous cycle lasting about 30 days. In the wild, mating usually occurs between December and March. The pair mates multiple times over the course of several days. The male grasps the female by the neck who responds with vocalization. Occasionally, he also bites her during courtship and is very aggressive during sexual encounters. Females can bear one litter each year. The male is not involved in raising the cubs.The female gives birth to a litter of one to five, mostly three cubs, after a gestation period of 93 ± 6 days. Cubs are born with closed eyes and weigh from 140 to 280 g (4.9 to 9.9 oz). Their spots are solid dark, rather than dark rings. Their eyes open after about 10 days. They are active within five weeks and fully weaned at around three months of age. They attain the adult coat pattern at around six months and become independent after around 10 months.Captive clouded leopards have an average lifespan of 11 years.
+One individual has lived to be almost 17 years old.Generation length of the clouded leopard is about seven years.
+
+
+== Threats ==
+
+Many of the remaining forest areas are too small to ensure the long-term persistence of clouded leopard populations. They are threatened by habitat loss following large–scale deforestation and commercial poaching for the wildlife trade. Skins, claws and teeth are offered for decoration and clothing, bones and meat as substitute for body parts of the tiger in traditional Asian medicine and tonics, and live animals for the pet trade.
+In Myanmar, 301 body parts of at least 279 clouded leopards, mostly skins and skeletons, were observed in four markets surveyed between 1991 and 2006. Three of the surveyed markets are situated on international borders with China and Thailand, and cater to international buyers. Implementation and enforcement of CITES is considered inadequate.In Nepal, 27 cases of clouded leopard body parts were discovered between November 1988 and March 2020 in nine districts of the country, comprising at least 51 individual clouded leopards. In 17 of these cases, the poachers and traders were arrested.
+
+
+== Conservation ==
+
+The clouded leopard is listed in CITES Appendix I and protected over most of its range. Hunting is banned in Bangladesh, China, India, Malaysia, Myanmar, Nepal, Taiwan, Thailand and Vietnam. It is not legally protected outside Bhutan's protected areas. Hunting is regulated in Laos. No information about its protection status is available from Cambodia. These bans, however, are poorly enforced in India, Malaysia and Thailand.In the United States, the clouded leopard is listed as endangered under the Endangered Species Act, prohibiting trade in live animals or body parts.International Clouded Leopard Day is celebrated each year on 4 August since 2018 in zoos and conservation organizations all over the world.
+
+
+=== In captivity ===
+
+Clouded leopards have been kept in zoos since the early 20th century. The international studbook was initiated in the 1970s. Coordinated breeding programs were started in the 1980s and encompass the European Endangered Species Programme, the Species Survival Plan, and the Indian Conservation Breeding Programme. As of 2014, 64 institutions keep clouded leopards, including six zoos in India:
+The zoo in Sipahijola Wildlife Sanctuary since 1996
+Darjeeling Zoo since 1996
+Aizawl Zoo since 2006
+Itanagar Zoo since 2009
+Gangtok Zoo since 2010
+Shillong Zoo since 2012Early captive-breeding programs involving clouded leopards were not successful, largely due to ignorance of their courtship behaviour. Males have the reputation of being aggressive towards females. For breeding success, it has been deemed extremely important that male and female clouded leopards are compatible. Introducing pairs at a young age gives them opportunities to bond and breed successfully. Facilities breeding clouded leopards need to provide the female with a secluded, off-exhibit area. There has been some recent captive breeding success using artificial insemination with cubs successfully born in 1992, 2015 and 2017.A study on morbidity and mortality rate of 271 captive clouded leopards across 44 zoos in Europe, Asia and Australia showed that 17% of them died because of respiratory disease, 12% due to maternal neglect and starvation, 10% from generalized infectious disease, 10% from digestive diseases, and 10% from trauma.In March 2011, two breeding females at the Nashville Zoo at Grassmere gave birth to three cubs, which were raised by zookeepers. Each cub weighed 0.23 kg (0.5 lb). In June 2011, two cubs were born at the Point Defiance Zoo & Aquarium. The breeding pair was brought from the Khao Kheow Open Zoo in Thailand in an ongoing education and research exchange program. Four cubs were born at Nashville Zoo in 2012. In May 2015, four cubs were born in Point Defiance Zoo & Aquarium.
+
+
+== In culture ==
+The Rukai people of Taiwan considered the hunting of clouded leopards a taboo. It is the state animal of the Indian state of Meghalaya. In the 1970s, the print of Rama Samaraweera's painting Clouded leopard was a best-seller in the USA.

+The okapi (; Okapia johnstoni), also known as the forest giraffe, Congolese giraffe, or zebra giraffe, is an artiodactyl mammal that is endemic to the northeast Democratic Republic of the Congo in central Africa. It is the only species in the genus Okapia. Although the okapi has striped markings reminiscent of zebras, it is most closely related to the giraffe. The okapi and the giraffe are the only living members of the family Giraffidae.
+The okapi stands about 1.5 m (4 ft 11 in) tall at the shoulder and has a typical body length around 2.5 m (8 ft 2 in). Its weight ranges from 200 to 350 kg (440 to 770 lb). It has a long neck, and large, flexible ears. Its coat is a chocolate to reddish brown, much in contrast with the white horizontal stripes and rings on the legs, and white ankles. Male okapis have short, distinct horn-like protuberances on their heads called ossicones, less than 15 cm (5.9 in) in length. Females possess hair whorls, and ossicones are absent.
+Okapis are primarily diurnal, but may be active for a few hours in darkness. They are essentially solitary, coming together only to breed. Okapis are herbivores, feeding on tree leaves and buds, grasses, ferns, fruits, and fungi. Rut in males and estrus in females does not depend on the season. In captivity, estrus cycles recur every 15 days. The gestational period is around 440 to 450 days long, following which usually a single calf is born. The juveniles are kept in hiding, and nursing takes place infrequently. Juveniles start taking solid food from three months, and weaning takes place at six months.
+Okapis inhabit canopy forests at altitudes of 500–1,500 m (1,600–4,900 ft). The International Union for the Conservation of Nature and Natural Resources classifies the okapi as endangered. Major threats include habitat loss due to logging and human settlement. Illegal mining and extensive hunting for bushmeat and skin have also led to a decline in populations. The Okapi Conservation Project was established in 1987 to protect okapi populations.
+
+
+== Etymology and taxonomy ==
+ 
+Although the okapi was unknown to the Western world until the 20th century, it may have been depicted since the early fifth century BCE on the façade of the Apadana at Persepolis, a gift from the Ethiopian procession to the Achaemenid kingdom.For years, Europeans in Africa had heard of an animal that they came to call the African unicorn. The animal was brought to prominent European attention by speculation on its existence found in press reports covering Henry Morton Stanley's journeys in 1887. In his travelogue of exploring the Congo, Stanley mentioned a kind of donkey that the natives called the atti, which scholars later identified as the okapi.When the British special commissioner in Uganda, Sir Harry Johnston, discovered some Pygmy inhabitants of the Congo being abducted by a showman for exhibition, he rescued them and promised to return them to their homes. The Pygmies fed Johnston's curiosity about the animal mentioned in Stanley's book. Johnston was puzzled by the okapi tracks the natives showed him; while he had expected to be on the trail of some sort of forest-dwelling horse, the tracks were of a cloven-hoofed beast.
+
+Though Johnston did not see an okapi himself, he did manage to obtain pieces of striped skin and eventually a skull. From this skull, the okapi was correctly classified as a relative of the giraffe; in 1901, the species was formally recognized as Okapia johnstoni.Okapia johnstoni was first described as Equus johnstoni by English zoologist Philip Lutley Sclater in 1901. The generic name Okapia derives either from the Mbuba name okapi or the related Lese Karo name o'api, while the specific name (johnstoni) is in recognition of Johnston, who first acquired an okapi specimen for science from the Ituri Forest.In 1901, Sclater presented a painting of the okapi before the Zoological Society of London that depicted its physical features with some clarity. Much confusion arose regarding the taxonomical status of this newly discovered animal. Sir Harry Johnston himself called it a Helladotherium, or a relative of other extinct giraffids. Based on the description of the okapi by Pygmies, who referred to it as a "horse", Sclater named the species Equus johnstoni. Subsequently, zoologist Ray Lankester declared that the okapi represented an unknown genus of the Giraffidae, which he placed in its own genus, Okapia, and assigned the name Okapia johnstoni to the species.In 1902, Swiss zoologist Charles Immanuel Forsyth Major suggested the inclusion of O. johnstoni in the extinct giraffid subfamily Palaeotraginae. However, the species was placed in its own subfamily Okapiinae, by Swedish palaeontologist Birger Bohlin in 1926, mainly due to the lack of a cingulum, a major feature of the palaeotragids. In 1986, Okapia was finally established as a sister genus of Giraffa on the basis of cladistic analysis. The two genera together with Palaeotragus constitute the tribe Giraffini.
+
+
+=== Evolution ===
+
+The earliest members of the Giraffidae first appeared in the early Miocene in Africa, having diverged from the superficially deer-like climacoceratids. Giraffids spread into Europe and Asia by the middle Miocene in a first radiation. Another radiation began in the Pliocene, but was terminated by a decline in diversity in the Pleistocene. Several important primitive giraffids existed more or less contemporaneously in the Miocene (23–10 million years ago), including Canthumeryx, Giraffokeryx, Palaeotragus, and Samotherium. According to palaeontologist and author Kathleen Hunt, Samotherium split into Okapia (18 million years ago) and Giraffa (12 million years ago). However, J. D. Skinner argued that Canthumeryx gave rise to the okapi and giraffe through the latter three genera and that the okapi is the extant form of Palaeotragus. The okapi is sometimes referred to as a living fossil, as it has existed as a species over a long geological time period, and morphologically resembles more primitive forms (e.g. Samotherium).In 2016, a genetic study found that the common ancestor of giraffe and okapi lived about 11.5 million years ago.
+
+
+== Characteristics ==
+
+The okapi is a medium-sized giraffid, standing 1.5 m (4 ft 11 in) tall at the shoulder. Its average body length is about 2.5 m (8 ft 2 in) and its weight ranges from 200 to 350 kg (440 to 770 lb). It has a long neck, and large and flexible ears. In sharp contrast to the white horizontal stripes on the legs and white ankles, the okapi's coat is a chocolate to reddish brown.  The distinctive stripes resemble those of a zebra. These features serve as an effective camouflage amidst dense vegetation. The face, throat, and chest are greyish white. Interdigital glands are present on all four feet, and are slightly larger on the front feet. Male okapis have short, hair-covered horn-like structures called ossicones, less than 15 cm (5.9 in) in length, which are similar in form and function to the ossicones of a giraffe. The okapi exhibits sexual dimorphism, with females 4.2 cm (1.7 in) taller on average, slightly redder, and lacking prominent ossicones, instead possessing hair whorls.The okapi shows several adaptations to its tropical habitat. The large number of rod cells in the retina facilitate night vision, and an efficient olfactory system is present. The large auditory bullae of the temporal bone allow a strong sense of hearing. The dental formula of the okapi is 0.0.3.33.1.3.3. Teeth are low-crowned and finely cusped, and efficiently cut tender foliage. The large cecum and colon help in microbial digestion, and a quick rate of food passage allows for lower cell wall digestion than in other ruminants.
+ 
+The okapi is easily distinguished from its nearest extant relative, the giraffe. It is much smaller than the giraffe and shares more external similarities with bovids and cervids. Ossicones are present only in the male okapi, while both sexes of giraffe possess this feature. The okapi has large palatine sinuses (hollow cavities in the palate), unique among the giraffids. Morphological features shared between the giraffe and the okapi include a similar gait – both use a pacing gait, stepping simultaneously with the front and the hind leg on the same side of the body, unlike other ungulates that walk by moving alternate legs on either side of the body – and a long, black tongue (longer in the okapi) useful for plucking buds and leaves, as well as for grooming.
+
+
+== Ecology and behaviour ==
+Okapis are primarily diurnal, but may be active for a few hours in darkness. They are essentially solitary, coming together only to breed. They have overlapping home ranges and typically occur at densities around 0.6 animals per square kilometre. Male home ranges average 13 km2 (5.0 sq mi), while female home ranges average 3–5 km2 (1.2–1.9 sq mi). Males migrate continuously, while females are sedentary. Males often mark territories and bushes with their urine, while females use common defecation sites. Grooming is a common practice, focused at the earlobes and the neck. Okapis often rub their necks against trees, leaving a brown exudate.The male is protective of his territory, but allows females to pass through the domain to forage. Males visit female home ranges at breeding time. Although generally tranquil, the okapi can kick and butt with its head to show aggression. As the vocal cords are poorly developed, vocal communication is mainly restricted to three sounds — "chuff" (contact calls used by both sexes), "moan" (by females during courtship) and "bleat" (by infants under stress). Individuals may engage in Flehmen response, a visual expression in which the animal curls back its upper lips, displays the teeth, and inhales through the mouth for a few seconds. The leopard is the main natural predator of the okapi.
+
+
+=== Diet ===
+
+Okapis are herbivores, feeding on tree leaves and buds, grasses, ferns, fruits, and fungi. They are unique in the Ituri Forest as they are the only known mammal that feeds solely on understory vegetation, where they use their 18-inch-long (46 cm) tongues to selectively browse for suitable plants. The tongue is also used to groom their ears and eyes. They prefer to feed in treefall gaps. The okapi has been known to feed on over 100 species of plants, some of which are known to be poisonous to humans and other animals. Fecal analysis shows that none of those 100 species dominates the diet of the okapi. Staple foods comprise shrubs and lianas. The main constituents of the diet are woody, dicotyledonous species; monocotyledonous plants are not eaten regularly. In the Ituri forest, the okapi feeds mainly upon the plant families Acanthaceae, Ebenaceae, Euphorbiaceae, Flacourtiaceae, Loganiaceae, Rubiaceae, and Violaceae.
+
+
+=== Reproduction ===
+
+Female okapis become sexually mature at about one-and-a-half years old, while males reach maturity after two years. Rut in males and estrous in females does not depend on the season. In captivity, estrous cycles recur every 15 days. The male and the female begin courtship by circling, smelling, and licking each other. The male shows his interest by extending his neck, tossing his head, and protruding one leg forward. This is followed by mounting and copulation.The gestational period is around 440 to 450 days long, following which usually a single calf is born, weighing 14–30 kg (31–66 lb). The udder of the pregnant female starts swelling 2 months before parturition, and vulval discharges may occur. Parturition takes 3–4 hours, and the female stands throughout this period, though she may rest during brief intervals. The mother consumes the afterbirth and extensively grooms the infant. Her milk is very rich in proteins and low in fat.As in other ruminants, the infant can stand within 30 minutes of birth. Although generally similar to adults, newborn calves have long hairs around the eye (resembling false eyelashes), a long dorsal mane, and long white hairs in the stripes. These features gradually disappear and give way to the general appearance within a year. The juveniles are kept in hiding, and nursing takes place infrequently. Calves are known not to defecate for the first month or two of life, which is hypothesized to help avoid predator detection in their most vulnerable phase of life. The growth rate of calves is appreciably high in the first few months of life, after which it gradually declines. Juveniles start taking solid food from 3 months, and weaning takes place at 6 months. Ossicone development in males takes 1 year after birth. The okapi's typical lifespan is 20–30 years.

+
+== Distribution and habitat ==
+The okapi is endemic to the Democratic Republic of the Congo, where it occurs north and east of the Congo River. It ranges from the Maiko National Park northward to the Ituri rainforest, then through the river basins of the Rubi, Lake Tele, and Ebola to the west and the Ubangi River further north. Smaller populations exist west and south of the Congo River. It is also common in the Wamba and Epulu areas. It is extinct in Uganda.The okapi inhabits canopy forests at altitudes of 500–1,500 m (1,600–4,900 ft). It occasionally uses seasonally inundated areas, but does not occur in gallery forests, swamp forests, and habitats disturbed by human settlements. In the wet season, it visits rocky inselbergs that offer forage uncommon elsewhere. Results of research conducted in the late 1980s in a mixed Cynometra forest indicated that the okapi population density averaged 0.53 animals per square kilometre. In 2008, it was recorded in Virunga National Park. There is also evidence that okapis were also observed in the Semuliki Valley in Uganda by Europeans, but later became extinct in the late 1970s. The Semuliki Valley provides a similar habitat to the Congo Basin.

+
+
+=== Threats and conservation ===
+ 
+The IUCN classifies the okapi as endangered. It is fully protected under Congolese law. The Okapi Wildlife Reserve and Maiko National Park support significant populations of the okapi, though a steady decline in numbers has occurred due to several threats. Other areas of occurrence are the Rubi Tele Hunting Reserve and the Abumombanzi Reserve. Major threats include habitat loss due to logging and human settlement. Extensive hunting for bushmeat and skin and illegal mining have also led to population declines. A threat that has emerged quite recently is the presence of illegal armed groups around protected areas, inhibiting conservation and monitoring actions. A small population occurs north of the Virunga National Park, but lacks protection due to the presence of armed groups in the vicinity. In June 2012, a gang of poachers attacked the headquarters of the Okapi Wildlife Reserve, killing six guards and other staff as well as all 14 okapis at their breeding center.The Okapi Conservation Project, established in 1987, works towards the conservation of the okapi, as well as the growth of the indigenous Mbuti people. In November 2011, the White Oak Conservation center and Jacksonville Zoo and Gardens hosted an international meeting of the Okapi Species Survival Plan and the Okapi European Endangered Species Programme at Jacksonville, which was attended by representatives from zoos from the US, Europe, and Japan. The aim was to discuss the management of captive okapis and arrange support for okapi conservation. Many zoos in North America and Europe currently have okapis in captivity.
+
+
+=== Okapis in zoos ===
+
+Around 100 okapis are in accredited Association of Zoos and Aquariums (AZA) zoos. The okapi population is managed in America by the AZA's Species Survival Plan, a breeding program that works to ensure genetic diversity in the captive population of endangered animals, while the EEP (European studbook) and ISB (Global studbook) are managed by Antwerp Zoo in Belgium, which was the first zoo to have an Okapi on display (in 1919), as well as one of the most successful in breeding them.In 1937, the Bronx Zoo became the first in North America to acquire an okapi. With one of the most successful breeding programs, 13 calves have been born there between 1991 and 2011. The San Diego Zoo has exhibited okapis since 1956, and their first okapi calf was born in 1962. Since then, there have been more than 60 okapis born at the zoo and the nearby San Diego Zoo Safari Park, the most recent being Mosi, a male calf born on 21 July 2017 at the zoo. The Brookfield Zoo in Chicago has also greatly contributed to the captive population of okapis in accredited zoos. The zoo has had 28 okapi births since 1959.Other North American zoos that exhibit and breed okapis include: Denver Zoo and Cheyenne Mountain Zoo (Colorado); Houston Zoo, Dallas Zoo, and San Antonio Zoo (Texas); Disney's Animal Kingdom, White Oak Conservation, Zoo Miami, and ZooTampa at Lowry Park (Florida); Los Angeles Zoo, Sacramento Zoo, and San Diego Zoo (California); Saint Louis Zoo (Missouri); Cincinnati Zoo and Botanical Garden and Columbus Zoo and Aquarium (Ohio); Memphis Zoo and Nashville Zoo (Tennessee); The Maryland Zoo in Baltimore (Maryland); Sedgwick County Zoo and Tanganyika Wildlife Park (Kansas); Roosevelt Park Zoo (North Dakota); Henry Doorly Zoo and Aquarium (Nebraska); Philadelphia Zoo (Pennsylvania); Potawatomi Zoo (Indiana); Oklahoma City Zoo and Botanical Garden (Oklahoma); and Blank Park Zoo (Iowa).In Europe, zoos that exhibit and breed okapis include: Chester Zoo, London Zoo, Marwell Zoo, The Wild Place, and Yorkshire Wildlife Park (United Kingdom); Dublin Zoo (Ireland); Berlin Zoo, Frankfurt Zoo, Wilhelma Zoo, Wuppertal Zoo, Cologne Zoo, and Leipzig Zoo (Germany); Zoo Basel  (Switzerland); Copenhagen Zoo (Denmark); Rotterdam Zoo and Safaripark Beekse Bergen (Netherlands); Dvůr Králové Zoo (Czech Republic); Wrocław Zoo (Poland); Bioparc Zoo de Doué and ZooParc de Beauval (France); and Lisbon Zoo (Portugal).In Asia, three Japanese zoos exhibit okapis: Ueno Zoo in Tokyo; Kanazawa Zoo and Zoorasia in Yokohama.

+The European rabbit (Oryctolagus cuniculus) or coney is a species of rabbit native to the Iberian Peninsula (including Spain, Portugal, and southwestern France), western France, and the northern Atlas Mountains in northwest Africa. It has been widely introduced elsewhere, often with devastating effects on local biodiversity. Its decline in its native range due to myxomatosis, rabbit calicivirus, overhunting and habitat loss has caused the decline of the Iberian lynx (Lynx pardinus) and Spanish imperial eagle (Aquila adalberti). It is known as an invasive species because it has been introduced to countries on all continents with the exception of Antarctica, and has caused many problems within the environment and ecosystems; in particular, European rabbits in Australia have had a devastating impact, due in part to the lack of natural predators there.
+The European rabbit is well known for digging networks of burrows, called warrens, where it spends most of its time when not feeding. Unlike the related hares (Lepus spp.), rabbits are altricial, the young being born blind and furless, in a fur-lined nest in the warren, and they are totally dependent upon their mothers. Much of the modern research into wild rabbit behaviour was carried out in the 1960s by two research centres. One was the naturalist Ronald Lockley, who maintained a number of large enclosures for wild rabbit colonies, with observation facilities, in Orielton, Pembrokeshire. Apart from publishing a number of scientific papers, he popularised his findings in a book The Private Life of the Rabbit, which is credited by Richard Adams as having played a key role in his gaining "a knowledge of rabbits and their ways" that informed his novel Watership Down. The other group was the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia, where numerous studies of the social behavior of wild rabbits were performed. Since the onset of myxomatosis, and the decline of the significance of the rabbit as an agricultural pest, few large-scale studies have been performed and many aspects of rabbit behaviour are still poorly understood.
+
+
+== Naming and etymology ==
+Because of its non-British origin, the species does not have native names in English or Celtic, with the usual terms "cony" and "rabbit" being foreign loanwords. "Rabbit" is also pronounced as rabbidge, rabbert (North Devon) and rappit (Cheshire and Lancashire). More archaic pronunciations include rabbette (15th-16th centuries), rabet (15th-17th centuries), rabbet (16th-18th centuries), rabatte (16th century), rabytt (17th century) and rabit (18th century). The root word is the Walloon rabett, which was once commonly used in Liège. Rabett itself is derived from the Middle Dutch robbe, with the addition of the suffix -ett.The term "cony" or "coney" antedates "rabbit", and first occurred during the 13th century to refer to the animal's pelt. Later, "cony" referred to the adult animal, while "rabbit" referred to the young. The root of "cony" is the old French connil or counil, of which the Norman plural was coniz, and later conis. Its forerunner is the Greek κύνικλος, from which the Latin cuniculus is derived. The origin of κύνικλος itself is unclear: Ælian, who lived during the third century, linked the word to Celtiberian and later authors relate it to its Basque name unchi; Varo and Pliny connected it to cuneus, which refers to a wedge, thus making reference to the animal's digging ability.The species' dwelling place is termed a warren or cony-garth. "Warren" comes from the Old English wareine, itself derived from the Old French warenne, varenne, or garenne. The root word is the Low Latin warenna, which originally signified a preserve in general, only to be later used to refer specifically to an enclosure set apart for rabbits and hares. "Cony-garth" derives from the Middle English conygerthe, which may be a compound of connynge+erthe (cony+earth). The term stems from the Old French conniniere or coninyere, and later conilliere. The root word is the Low Latin cunicularia, the feminine form of the adjective cunicularius, which pertains to the rabbit.
+
+
+== Taxonomy ==
+Originally assigned to the genus Lepus, the European rabbit was consigned to its own genus in 1874 on account of its altricial young, its burrowing habits, and numerous skeletal characters. It is superficially similar to the North American cottontails (Sylvilagus) in that they are born blind and naked, have white flesh, and little sexual dimorphism. However, they differ in skull characteristics, and cottontails do not habitually construct their own burrows as the European rabbit does. Molecular studies confirm that the resemblance between the two is due to convergent evolution, and that the European rabbit's closest relatives are the hispid hare, the riverine rabbit, and the Amami rabbit. The oldest known fossils attributed to the modern European rabbit species are around 0.5 Ma old (Middle Pleistocene).The cladogram is from Matthee et al., 2004, based on nuclear and mitochondrial gene analysis.
+
+
+=== Subspecies ===
+As of 2005, six subspecies are recognised by MSW3. Genetic studies undertaken in 2008, however, indicate only two subspecies, O. c. algirus and O. c. cuniculus, with a hybrid zone connecting the two populations in central Iberia.
+
+
+== Description ==
+
+The European rabbit is smaller than the European hare and mountain hare, and lacks black ear tips, as well as having proportionately shorter legs. An adult European rabbit can measure 40 centimetres (16 in) in length, and weigh 1,200–2,000 grams (2.6–4.4 lb). The hind foot measures 8.5–10 cm (3.3–3.9 in) in length, while the ears are 6.5–7.5 cm (2.6–3.0 in) long from the occiput.Size and weight vary according to food and habitat quality, with rabbits living on light soil with nothing but grass to feed on being noticeably smaller than specimens living on highly cultivated farmlands with plenty of roots and clover. Pure European rabbits weighing 5 kg (11 lb) and upwards are uncommon, but are occasionally reported. One large specimen, caught in February 1890 in Lichfield, was weighed at 2.8 kilograms (6 lb 2 oz). Unlike the brown hare, the male European rabbit is more heavily built than the female. The penis is short, and lacks a baculum and true glans.The fur of the European rabbit is generally greyish-brown, but this is subject to much variation. The guard hairs are banded brown and black, or grey, while the nape of the neck and scrotum are reddish. The chest patch is brown, while the rest of the underparts are white or grey. A white star shape is often present on kits' foreheads, but rarely occurs in adults. The whiskers are long and black, and the feet are fully furred and buff-coloured. The tail has a white underside, which becomes prominent when escaping danger. This may act as a signal for other rabbits to run.Moulting occurs once a year, beginning in March on the face and spreading over the back. The underfur is completely replaced by October–November. The European rabbit exhibits great variation in colour, from light sandy, to dark grey and completely black. Such variation depends largely on the amount of guard hairs relative to regular pelage. Melanists are not uncommon in mainland Europe, though albinoes are rare.
+
+
+== Life history and behaviour ==
+
+
+=== Social and territorial behaviours ===
+The European rabbit lives in warrens that contain 2-10 other individuals living in smaller groups to ensure greater breeding success. Territoriality and aggression contribute greatly to the rabbits' maturation process, and help ensure survival of the population. Females tend to be more territorial than males, although the areas most frequented by females are not defended. Territories are marked with dung hills. The size of the species' home range varies according to habitat, food, shelter, cover from predators, and breeding sites, though it is generally small, encompassing about 0.3-0.7 hectares. Except during times of low rabbit density and abundance of high-quality food, male ranges tend to be larger than those held by females. The European rabbit rarely strays far from its burrow; when feeding on cultivated fields, it typically only moves 25 m away from its burrow, and rarely 50 m. It may, however, move as far as 500 m after an abrupt change in environment, such as a harvest. This behaviour may be an antipredator adaptation, as rabbits in areas where predators are under rigorous control may move three times further from their burrows than those in areas without predator management.The European rabbit is a gregarious animal, which lives in stable social groups centred around females sharing access to one or more burrow systems. Social structures tend to be looser in areas where burrow construction is relatively easy. Dominance hierarchies exist in parallel for both bucks and does. Among bucks, status is determined through access to does, with dominant bucks siring the majority of the colony's offspring. The dominant does have priority access to the best nesting sites, with competition over such sites often leading to serious injury or death. Subordinate does, particularly in large colonies, typically resort to using single-entrance breeding spots far from the main warren, thus making themselves vulnerable to fox or badger predation.
+
+
+=== Reproduction and development ===
+In the European rabbit's mating system, dominant bucks exhibit polygyny, whereas lower-status individuals (both bucks and does) often form monogamous breeding relationships. Rabbits signal their readiness to copulate by marking other animals and inanimate objects with an odoriferous substance secreted though a chin gland, in a process known as "chinning". Though male European rabbits may sometimes be amicable with one another, fierce fights can erupt among bucks during the breeding season, typically January to August. A succession of litters (usually three to seven kittens each) are produced, but in overpopulated areas, pregnant does may lose all their embryos through intrauterine resorption. Shortly before giving birth, the doe constructs a separate burrow known as a "stop" or "stab", generally in an open field away from the main warren. These breeding burrows are typically a few feet long and are lined with grass and moss, as well as fur plucked from the doe's belly. The breeding burrow protects the kits from adult bucks and predators.The gestation period of the European rabbit is 30 days, with the sex ratio of male to female kits tending to be 1:1. Greater maternal investment over male offspring may result in higher birth weights for bucks. Kits born to the dominant buck and doe—which enjoy better nesting and feeding grounds—tend to grow larger and stronger and to become more dominant than those born to subordinate rabbits. Not uncommonly, European rabbits  mate again immediately after giving birth, with some specimens having been observed to nurse previous young whilst pregnant.Female European rabbits nurse their kits once a night, for only a few minutes. After suckling is complete, the doe seals the entrance to the stop with soil and vegetation. In its native Iberian and southern French range, European rabbit young have a growth rate of 5 g (0.18 oz) per day, though such kittens in non-native ranges may grow 10 g (0.35 oz) per day. Weight at birth is 30–35 g (1.1–1.2 oz) and increases to 150–200 g (5.3–7.1 oz) by 21–25 days, during the weaning period. European rabbit kits are born blind, deaf, and nearly naked. The ears do not gain the power of motion until 10 days of age, and can be erected after 13. The eyes open 11 days after birth. At 18 days, the kittens begin to leave the burrow. Sexual maturity in bucks is attained at 4 months, while does can begin to breed at 3-5 months.
+
+
+=== Burrowing behaviour ===
+The European rabbit's burrows occur mostly on slopes and banks, where drainage is more efficient. The burrow entrances are typically 10–50 cm in diameter, and are easily recognisable by the bare earth at their mouths. Vegetation growth is prevented by the constant passing and repassing of the resident rabbits. Big burrows are complex excavations which may descend to depths of several feet. They are not constructed on any specified plan, and appear to be enlarged or improved as a result of the promiscuous activity of several generations. Digging is done by pulling the soil backwards with the fore feet and throwing it between the hind legs, which scatter the material with kicking motions. While most burrows are dug from the outside, some warrens feature holes dug from the inside, which act as emergency exits when escaping from predators below ground. These holes usually descend perpendicularly to 3–4 feet, and their mouths lack the bare-earth characteristic of burrow entrances. While kits sleep in chambers lined with grass and fur, adults sleep on the bare earth, likely to prevent damp, with warmth being secured by huddling. Although both sexes dig, does do so more skillfully, and for longer periods.
+
+
+=== Communication ===
+The European rabbit is a relatively quiet animal, though it has at least two vocalisations. The best-known is a high treble scream or squeal. This distress call has been likened to the cry of a piglet. This sound is uttered when in extreme distress, such as being caught by a predator or trap. During the spring, bucks express contentment by emitting grunting sounds when approaching other rabbits. These grunts are similar to shrill hiccups, and are emitted with the mouth closed. Aggression is expressed with a low growl.
+
+
+== Ecology ==
+
+
+=== Habitat ===
+The European rabbit's ideal habitat consists of short grasslands with secure refuge (such as burrows, boulders, hedgerows, scrub, and woodland) near feeding areas. It may dwell up to treeline, as long as the land is well-drained and shelter is available. The size and distribution of its burrow systems depend on the type of soil present; in areas with loose soil, it selects sites with supporting structures, such as tree roots or shrubs to prevent burrow collapse. Warrens tend to be larger and have more interconnected tunnels in areas with chalk than those in sand. In large coniferous plantations, the species only occurs on peripheral areas and along fire breaks and rides.
+
+
+=== Diet ===
+The European rabbit eats a wide variety of herbage, especially grasses, favouring the young, succulent leaves and shoots of the most nutritious species, particularly fescues. In mixed cultivated areas, winter wheat is preferred over maize and dicotyledons. During the summer, the European rabbit feeds on the shortest, and therefore less nutritious grass swards, thus indicating that grazing grounds are selected through antipredator considerations rather than maximising food intake. In times of scarcity, the rabbit increases its food intake, selecting the parts of the plant with the highest nitrogen content. Hungry rabbits in winter may resort to eating tree bark. Blackberries are also eaten, and captive-bred European rabbits have been fed on fodder consisting of furze and acorns, which can lead to considerable weight gain. The European rabbit is a less fussy eater than the brown hare; when eating root vegetables, the rabbit eats them whole, while the hare tends to leave the peel. Depending on the body's fat and protein reserves, the species can survive without food in winter for about 2–8 days. Although herbivorous, cases are known of rabbits eating snails.Like other leporids, the European rabbit produces soft, mucus-covered faecal pellets, which are ingested directly from the anus. The soft pellets are produced posterior to the colon in the hind gut soon after the excretion of hard pellets and the stomach begins to fill with newly grazed food. The soft pellets are filled with protein-rich bacteria, and pass down to the rectum in glossy clusters. The rabbit swallows them whole, without perforating the enveloping membrane.
+
+
+=== Predators ===
+The European rabbit is prey to many different predatory species. Foxes, dingoes, wolves, lynxes, wolverines, and dogs kill both adult and young rabbits by stalking and surprising them in the open, but relatively few rabbits are caught this way, as they can quickly rush back to cover with a burst of speed. Further, evidence from a study in Spain suggests they may avoid areas where the recent scat of predators which have eaten rabbit is detected. Both foxes and badgers dig out kittens from shallow burrows, with the latter predators being too slow to catch adult rabbits. Both wild and domestic cats can stalk and leap upon rabbits, particularly young specimens leaving their burrows for the first time. Wildcats take rabbits according to availability; in eastern Scotland, where rabbits are abundant, they can make up over 90% of the wildcats' diet. Most domestic cats are incapable of killing healthy, full-grown adults, but will take weak and diseased ones. Does can be fiercely protective of their kits, having been observed to chase away large cats and mustelids, including ferrets, stoats, and weasels. However, rabbits typically run from mustelids, and may fear them innately. Cases are known of rabbits becoming paralysed with fear and dying when pursued by stoats or weasels, even when rescued unharmed.The European rabbit makes up 85% of the polecat's diet, and its availability is important to the success of breeding female mink. Brown rats can be a serious threat to kittens, as they will reside in rabbit burrows during the summer, and attack them in groups. Although many birds of prey are capable of killing rabbits, few are strong enough to carry them. Large species, such as golden and sea eagles, may carry rabbits back to their nests, while small eagles, buzzards, and harriers struggle to do so. Hawks and owls typically only carry off very small kits.
+
+
+=== Diseases and parasites ===
+The European rabbit is the only species fatally attacked by myxomatosis. The most lethal strain has a five-day incubation period, after which the eyelids swell, with the inflammation quickly spreading to the base of the ears, the forehead, and nose. At the same time, the anal and genital areas also swell. During the last stages of the disease, the swellings discharge a fluid rich in viral material, with death usually following on the 11th-12th day of infection. In Britain, the primary carrier of myxomatosis is the flea Spilopsyllus cuniculi, while in Australia it is mosquitoes.
+Rabbit haemorrhagic disease (RHD), also known as viral haemorrhagic disease or rabbit calicivirus disease in Australia, is specific to the European rabbit, and causes lesions of acute necrotising hepatitis, disseminated intravascular coagulation, and haemorrhaging, mainly in the lungs. Susceptible specimens may die within 30 hours of infection. Most rabbits in the UK are immune to RHD, due to exposure to a weaker strain.
+
+
+== Human relationship with rabbits ==
+
+Recent research has shown that all European rabbits carry common genetic markers and descend from one of two maternal lines. These lines originated between 12,000 and 6.5 million years ago when glaciers isolated two herds, one on the Iberian Peninsula and the other in Southern France. Humans likely began hunting rabbits as a food source, but further research needs to be done to verify this. Little comprehensive evidence of the relationship of humans with European rabbits is documented until the medieval period.Humans' relationship with the European rabbit was first recorded by the Phoenicians prior to 1000 BC, when they termed the Iberian Peninsula i-Shaphan-ím (literally, the land of the hyraxes). This phrase closely resembles related modern Hebrew: I (אי) meaning island and shafan (שפן) meaning hyrax, plural shfaním (שפנים). Phoenicians called the local rabbits 'hyraxes' because rabbits resemble hyraxes in some ways, and hyraxes are native to Phoenicia, unlike rabbits. Hyraxes, like rabbits, are not rodents. One theory states that the Romans converted the phrase i-Shaphan-ím, with influence from the Greek Spania, to its Latin form, Hispania, which evolved in all the Iberian languages - into Castilian España, Portuguese Espanha, Catalan Espanya (English "Spain"), and such other variations in modern languages. Different views have been voiced on the precise meaning of shafan, but the balance of opinion appears to indicate that the hyrax is indeed the intended meaning.Like the Phoenicians, neither the later Greek nor Roman colonizers had a specific name for the rabbit, because the species is not native to Greece and Italy (though it is present there nowadays). They commonly called it "small hare" and "small digging hare", in contrast to the European hare, which is larger and doesn't make burrows. Catullus used the name cuniculus (a latinization of the Iberian word kiniklos and the etymological origin of the Castilian name conejo, Portuguese coelho and Catalan conill, and the old English name, coney), and referenced its abundance in Celtiberia by calling this region cuniculosa, i.e. rabbit-ridden.The European rabbit is the only rabbit species that has been domesticated and all 305 global rabbit breeds— from Netherland Dwarf to Flemish Giant— are descendants of the European rabbit. Rabbits are an example of an animal that can be treated as a food, a pet, or a pest by different members of the same culture. In some urban areas, infestations of feral European rabbits (descended from pets) have become a problem. Helsinki, for example, host to one of the northernmost populations of the species, had an estimated 2,500 European rabbits at the end of 2006, doubling to 5,000 by autumn 2007. In Iceland, populations of O. cuniculus are found in urban Reykjavik as well as in the Vestmannaeyjar archipelago. In Finland, the introduced European rabbit vies with the native lagomorphs: the European hare and the mountain hare.
+
+
+=== As an introduced species ===
+
+The European rabbit has been introduced as an exotic species into several environments, often with harmful results to vegetation and local wildlife, making it an invasive species. The first known mention of the rabbit as an invasive species (and possibly the first documented instance of an invasive species ever) was made in regard to the introduction of the rabbit to the Balearic Islands after the Roman conquest of the first century BCE. According to both Strabo and Pliny the Elder, the multiplying rabbits caused famines by destroying crop yields and even collapsed trees and houses with their burrowing. The inhabitants petitioned Augustus for help, who sent troops to curb the rabbit population with the help of ferrets.Other locations where the European rabbit was introduced include Great Britain; the Hawaiian Islands of Laysan Island (in 1903) and Lisianski Island; Oceania's Macquarie Island; Washington's Smith Island and San Juan Island (around 1900 and later spreading to the other San Juan Islands); several islands off the coast of Southern Africa (including Robben Island); and Australia and New Zealand. The two accounts over the introduction of rabbits in Ukraine are conflicting. One holds that the species was brought there in the early 20th century by Austrian nobleman Graf Malokhovsky, who released them on his estate near the Khadzhibey Estuary, while another holds that rabbits were first brought to Kherson from Switzerland in 1894-1895 by landowner Pinkovsky.
+
+
+==== In the British Isles ====
+The European rabbit is widespread in both Great Britain, Ireland, and most islands, except for Isles of Scilly, Rùm, Tiree, and some small Scottish islands, such as Gunna, Sanday, and most of the Treshnish Isles. It was likely first brought to Britain by the Normans after the 1066 conquest of England, as no pre-Norman British allusions to the animal have been found. The rabbit was nonetheless scarce or absent throughout most of England a short time afterwards, as warrens are not mentioned in the Domesday Book or any other 11th-century documents. Rabbits became well known, but not necessarily accepted members of British fauna between the 12th and 13th centuries, with the first real evidence of their presence consisting of a number of bones from the midden of Rayleigh Castle, which was occupied from the 11th-13th centuries. The first references to rabbits in Ireland occur roughly at the same time as English ones, thus indicating another Norman introduction. They had become plentiful, probably at a local level, by the 13th century, as indicated by an inquisition of Lundy Island made in 1274 describing how 2,000 rabbits were caught annually. Subsequent allusions in official documents became more frequent, with the species later becoming an important food item in feasts.Increases in truly wild populations occurred slowly, primarily in the coastal areas and lowland heaths of Breckland and Norfolk. Notable population increases occurred after 1750, when changes in agricultural practices created favourable habitat, and increasing interest in game management resulted in intensive predator control campaigns. Although now common in the Scottish lowlands, the species was little known in Scotland before the 19th century. Until then, it was confined to portions of the Edinburgh district at least as far back as the 16th century, certain islands and the coastal sand dunes of the Scottish mainland. Although unknown in Caithness in 1743, the species became well established there by 1793. Myxomatosis entered Britain from France in 1953, and reached Ireland by 1954, prompting the RSPB to set up "mercy squads" meant to euthanise myxomatous rabbits. Major myxomatosis outbreaks still occur in Britain, peaking twice annually in during spring and especially in the late summer or autumn periods, though immunity has reduced the mortality rate from 99% to 5-33%.Between 1996 and 2018, rabbit numbers fell by 88% in the east Midlands, 83% in Scotland, and 43% across the whole of the UK. Numbers are still falling (in 2021). Pip Mountjoy, Shifting Sands project manager at Natural England said, "They (rabbits) are actually an endangered species in their native region on the Iberian peninsula. It's surprising for people that rabbits are important in some ecosystems. We think of them as a pest but in Britain they are a keystone species – they act as landscape managers and a lot of other species rely on them." The Shifting Sands project aims to encourage landowners to create safe habitats for rabbits, consisting of piles of branches placed near existing rabbit warrens. Species that depend in rabbits' grazing habits include purple milk vetch, rare spring sedge, spring speedwell, prostrate perennial knawel, caterpillars of the lunar yellow underwing moth, stone curlew, and the large blue butterfly.
+
+
+==== In Australia ====
+
+Twenty-four specimens of the European rabbit were introduced to Australia in 1859 by estate owner Thomas Austin in Victoria. Their descendants multiplied and spread throughout the country due to the lack of natural predators, a conducive habitat (provided by widespread farming), and the mild Australian winters that allowed year-round breeding. Australia's native equivalent, the bilby, was quickly pushed out by the invasive rabbit. (The bilbies are endangered, but are now making a comeback due to government protection.) Between 1901 and 1907, Australia built an immense "rabbit-proof fence" to halt the westward expansion of the infestation. The European rabbit, however, can not only jump very high, but also burrow underground, making fencing essentially futile. 
+During the 1950s, the intentional introduction of a virus that causes myxomatosis provided some relief in Australia, but not in New Zealand, where the insect vectors necessary for the spread of the disease were not present. Myxomatosis can also infect pet rabbits (the same species). Today's remaining feral rabbits in Australia are largely immune to myxomatosis. A second deadly rabbit virus, rabbit hemorrhagic disease (RHD), has been cleared in Australia as a biological control agent and has already killed millions of the European rabbits there. RHD was also introduced—illegally— in New Zealand with less success due to improper timing.
+
+
+==== In Chile ====
+The exact date on which the European rabbit was introduced into Chile is unknown, though the first references to it occur during the mid-18th century. By the 19th century, several authors referred to the presence of both rabbits and rabbit hutches in central Chile. The importation and breeding of rabbits was encouraged by the state, as rabbits were seen as cheap sources of food for peasants. Whether or not their escape into the wild was intentional is unknown, but warnings over the dangers of feral rabbits were raised during the early 20th century, and the species had propagated dramatically by the late 1920s in central Chile, Tierra del Fuego, and the Juan Fernández Islands. In the 1930s, the state sought to tackle the rabbit problem by banning fox hunting, though it was later discovered that indigenous South American foxes rarely preyed on rabbits, preferring native species. In modern times, the European rabbit problem has not been resolved definitively, though a deliberate outbreak of myxomatosis in Tierra del Fuego successfully reduced local rabbit populations. The species remains a problem in central Chile and on Juan Fernández, despite international financing.
+
+
+=== Domesticated rabbits ===
+
+The European rabbit is the only rabbit to be widely domesticated, for food or as a pet. It was first widely kept in ancient Rome, where fetal rabbits were known as laurices and considered a delicacy, and has been refined into a wide variety of breeds during and since the Middle Ages.
+Domesticated rabbits have mostly been bred to be much larger than wild rabbits, though selective breeding has produced a range of sizes from "dwarf" to "giant", which are kept as food animals and pets across the world. They have as much color variation among themselves as other livestock and pet animals. Their fur is prized for its softness; today, Angora rabbits are raised for their long, soft fur, which is often spun into yarn. Other breeds are raised for the fur industry, particularly the Rex, which has a smooth, velvet-like coat and occurs in a wide variety of colors and sizes.
+
+
+=== Meat and fur ===
+In the United Kingdom, rabbit was a popular food source for the poorer classes. Among wild rabbits, those native to Spain were reputed to have the highest meat quality, followed by those in the Ardennes. As rabbits hold very little fat, they were hardly ever roasted, being instead boiled, fried, or stewed.The pelt of the rabbit is heavier and more durable than the hare's. Marshall calculated that the value of the skin in proportion to the carcass was greater than that of the sheep and ox. Its fur is primarily used for felting or hats. It is also dyed or clipped, and sold as imitations of more valuable furbearers, such as fur seal. Although cheap and easily acquired, rabbit fur has little durability.
+
+
+=== Conservation status ===
+ 
+Though the European rabbit thrives in many of the locations where it was introduced, in its native Iberia, populations are dwindling. In 2005, the Portuguese Institute for Nature Conservation and Forests classified O. cuniculus in Portugal as "near threatened", while in 2006, Spanish authorities (SECEM) reclassified it in Spain as "vulnerable". In 2018, the International Union for Conservation of Nature reclassified O. cuniculus in Spain, Portugal, and France as "endangered", due to the extent of recent declines. However, worldwide, the species is endangered.

+The scimitar oryx (Oryx dammah), also known as the scimitar-horned oryx and the Sahara oryx, is a Oryx species that was once widespread across North Africa. In 2000, it was declared extinct in the wild on the IUCN Red List.
+A captive bred group was released into an acclimation enclosure within the Ouadi Rimé-Ouadi Achim Faunal Reserve in 2016, then reintroduced into the wild. An additional 21 individuals were released into the acclimation enclosure in 2017. The first ones to be relocated were released into the wild in 2016 and have adapted well to their surroundings. In 2017, another herd of 75 scimitar-horned oryxes arrived in an operation led by Chad's Ministry of Environment and Fisheries and the Sahara Conservation Fund. In 2021, 60 new calves were born, bringing the number in the wild to about 400. This particular oryx can survive for months or even years without drinking water. A grazing animal, it derives most of its daily moisture intake from plants. 
+The scimitar oryx has a long taxonomic history since its scientific description in 1816 by Lorenz Oken, who named it Oryx algazel. This antelope stands a little more than 1 m (3.3 ft) at the shoulder. The males weigh 140–210 kg (310–460 lb) and the females weigh 91–140 kg (201–309 lb). The coat is white with a red-brown chest and black markings on the forehead and down the length of the nose. The calves are born with a yellow coat without distinguishing marks; their coats change to adult coloration at 3–12 months old.
+The scimitar oryx formed herds of mixed sexes of up to 70 members, usually guided by the bulls. They inhabited semideserts and deserts and were adapted to live in extreme heat, with their efficient cooling mechanism and very low requirement of water. Scimitar oryx feed on foliage, grasses, succulent plants, and plant parts during the night or early morning. Births peak between March and October. After a gestation of 8-9 months, one calf is born. Soon after, the female has a postpartum estrus.
+The decline of the scimitar oryx population began as a result of climate change during the Neolithic period, and later it was hunted extensively for its horns. Today, it is bred in captivity in special reserves in Tunisia, Morocco, and Senegal, and on private exotic animal ranches in the Texas Hill Country. In 2016, a reintroduction program was launched and currently a small herd has been successfully reintroduced in Chad.The scimitar oryx was domesticated in Ancient Egypt and is believed to have been used as food and sacrificed as offerings to gods. Wealthy people in Ancient Rome also bred them. The use of their valuable hides began in the Middle Ages. The unicorn myth may have originated from sightings of a scimitar oryx with a broken horn.The scimitar oryx was the emblem of the ancient Egyptian Oryx nome and today is the animal symbol of the Sahara Conservation Fund.
+
+
+== Taxonomy and naming ==
+The scimitar oryx is a member of the genus Oryx and the family Bovidae. German naturalist Lorenz Oken first described it in 1816, naming it Oryx algazel. The nomenclature has undergone various changes since then, with the introduction of names such as Oryx tao, O. leucoryx, O. damma, O. dammah, O. bezoarticus, and O. ensicornis. In 1826, Philipp Jakob Cretzschmar used the name Oryx ammah for the species. A year later, the name Oryx leucoryx came into use, but as this was a synonym of the Arabian oryx (then called Oryx beatrix), it was abandoned, and Oryx algazel was accepted once more. Over 100 years later in 1951, Sir John Ellerman and Terence Morrison-Scott found that the name Oryx algazel was also ineligible for use. Finally, in January 1956, the International Trust for Zoological Nomenclature accepted Oryx dammah as the scientific name. No more changes have been made since then, though many papers published after 1956 created confusion by using names such as O. gazella tao.Its scientific name, Oryx dammah, is derived from: Ancient Greek ὄρυξ (orux), meaning a gazelle or antelope (originally a pickaxe); Latin damma (fallow deer or antelope); and Arabic dammar (sheep). The scimitar oryx is named for its horns, which resemble scimitars. Its common name in English is "scimitar-horned oryx", or simply "scimitar oryx".
+
+
+== Genetics and evolution ==
+
+The scimitar oryx has 58 chromosomes - one pair of large submetacentric autosomes and 27 acrocentric autosomal pairs. The X and Y chromosomes are the largest and smallest acrocentrics. The first molecular study of this species (published in 2007) observed genetic diversity among European, North American, and some other captive groups. Divergence was found within the mitochondrial DNA haplotypes, and was estimated to have taken place between 2.1 and 2.7 million years ago. Population increases occurred about 1.2 and 0.5 million years ago.In another study, intended to note genetic differences between Oryx species, karyotypes of Oryx species and subspecies – namely O. gazella, O. b. beisa, O. b. callotis, O. dammah, and O. leucoryx – were compared with the standard karyotype of Bos taurus. The number of autosomes in all karyotypes was 58. The X and Y chromosomes were conserved in all five species.
+
+
+== Physical description ==
+
+The scimitar oryx is a straight-horned antelope that stands just over 1 m (3.3 ft) at the shoulder. The males weigh 140–210 kg (310–460 lb) and the females 91–140 kg (201–309 lb). The body measures 140–240 cm (55–94 in) from the head to the base of the tail. The tail is 45–60 cm (18–24 in) long and ends with a tuft. They are sexually dimorphic with males being larger than females.Its coat is white with a red-brown chest and black markings on the forehead and down the length of the nose. The coat reflects the sun's rays, while the black portions and the tip of the tongue provide protection against sunburn. The white coat helps to reflect the heat of the desert. Calves are born with yellow coats and lack distinguishing marks, which appear later in life. Their pelage changes to adult coloration at 3–12 months old.Both male and female oryxes have horns, with the females' being more slender. The horns are long, thin, and symmetrical, and curve backward (a distinctive feature of this species); they can reach 1.0 to 1.2 m (3 ft 3 in to 3 ft 11 in) in both sexes. The hollow walls of the horns are so thin that they can easily break. The female's udder has four teats. The large, spreading hooves are well adapted to allow these antelopes to walk on the sand of their dry habitats. A scimitar oryx can live as long as 20 years. At Smithsonian National Zoo, a female oryx died at 21, an exceptional age since females generally have a lifespan of about 15 years.
+
+
+== Diseases and parasites ==
+The scimitar oryx can be infected with cryptosporidiosis, a parasitic disease caused by protozoan parasites of the genus Cryptosporidium in the phylum Apicomplexa. A study in 2004 revealed that C. parvum or similar organisms infected 155 mammal species, including the scimitar oryx. An analysis in 2005 found Cryptosporidium parasites in stool samples from 100 mammals, including the scimitar oryx. Oocysts of a new parasite, Eimeria oryxae, have been discovered in the feces of a scimitar oryx from Zoo Garden in Riyadh. In France, Streptococcus uberis was isolated for the first time in an oryx. It had caused vegetative endocarditis in the animal, leading to fatal congestive heart failure.
+
+
+== Ecology and behavior ==
+The scimitar oryx was a very sociable animal and traveled in herds of two to 40 individuals, generally, led by a dominant bull. This species once gathered in groups of several thousand for migration. During the wet season, they migrated north into the Sahara. Scimitar oryx are diurnal. In the cool early mornings and evenings, they rest under trees and shrubs, or if neither is available, they dig depressions in the soil with their hooves and rest there. Males fight often, but not for long and not violently. Predators, such as lions, leopards, hyenas, cheetahs, golden jackals, vultures, and Cape hunting dogs, mostly kill weak and young oryx.
+
+
+=== Adaptations ===
+
+With a metabolism that functions at the high temperatures prevalent in their habitats, scimitar oryxes need less water for evaporation to help conduct heat away from the body, enabling them to go for long periods without water. They can allow their body temperatures to rise to almost 46.5 °C (115.7 °F) before beginning to perspire. In times of ample supply, oryx can use fluid loss through urination and feces to lower their body temperatures to below 36 °C (97 °F) at night, giving more time before reaching maximum body temperature the following day. They can tolerate high temperatures that would be lethal to most mammals. They have a network of fine blood vessels that carries  blood from the heart to the brain, passing close to the nasal passage, thus allowing the blood to cool by up to 3 °C (5 °F) before reaching the brain, which is one of the more heat-sensitive organs of the body.
+
+
+=== Diet ===
+The habitat of the scimitar oryx in the wild was steppe and desert, where they ate foliage, grass, herbs, shrubs, succulent plants, legumes, juicy roots, buds, and fruit. They can survive without water for 9-10 months because their kidneys prevent water loss from urination – an adaptation to desert habitats. They can get water from water-rich plants such as the wild melon (Citrullus colocynthis) and Indigofera oblongifolia and from the leafless twigs of Capparis decidua. In the night or early morning, they often search for plants such as Indigofera colutea, which produce a hygroscopic secretion that fulfills water requirements. They eat tuft grasses such as Cymbopogon schoenanthus after rains, but they normally prefer more palatable grasses, such as Cenchrus biflorus, Panicum laetum, and Dactyloctenium aegyptium. When the dry season begins, they feed on the seedpods of Acacia raddiana, and during the dry season, they rely on perennial grasses of genera such as Panicum (especially Panicum turgidum) and Aristida, and browse plants such as Leptadenia species, Cassia italica, and Cornulaca monacantha.
+
+
+=== Reproduction ===
+
+Both males and females reach sexual maturity at 18-24 months of age. Births peak between March and October. Mating frequency is greater when environmental conditions are favorable. In zoos, males are sexually most active in autumn. The estrous cycle lasts roughly 24 days, and females experience an anovulatory period in spring. Periods between births are less than 332 days, showing that the scimitar oryx is polyestrous.Courting is done by means of a mating circle; the male and female stand parallel to one another, facing in opposite directions, and then circle around each other until the female allows the male to mount from behind. If the female is not ready to mate, she runs away and circles in the reverse direction. Pregnant females leave the herd for a week, give birth to the calf, and mate again during their postpartum estrus; thus, they can produce one calf a year. Gestation lasts about nine months, after which a single calf is born, weighing 10–15 kg (22–33 lb). Twin births are very rare - only 0.7% of the births observed in one study. Both mother and calf return to the main herd within hours of the birth. The female separates herself from the herd for a few hours while she nurses the calf. Weaning starts at 3.5 months, and the young become fully independent around 14 weeks old.
+
+
+== Habitat and distribution ==
+The scimitar oryx once inhabited grassy steppes, semideserts and deserts in a narrow strip of central north Africa (Niger and Chad). It was reintroduced in Libya. It was widespread on the fringes of the Sahara, mainly in subdesert steppe, the grassy zone between the real desert and the Sahel, an area characterized by an annual rainfall of 75–150 mm (3.0–5.9 in). In 1936, a single herd of 10,000 scimitar oryxes was seen in the steppe area of Chad. By the mid-1970s, Chad was home to more than 95% of the world population of this species.
+
+
+== Status and conservation ==
+
+Following the Neolithic Subpluvial, around 7500 to 3500 BC, the "green Sahara" became dry and the scimitar oryx's population began to decline due to a loss of suitable habitat.  This was further exacerbated by humans who hunted the scimitar oryx for both its meat and horns.  The northern population was already almost lost before the 20th century.  With the introduction of horses and firearms during the 20th century, nomadic hunters were able to decimate populations. The decline of the southern population accelerated as Europeans began to settle the area and hunt them for meat, hides, and horn trophies. French involvement in World War II and the civil war in Chad that started in the 1960s are thought to have caused heavy decreases of the species through an increase in hunting for food. Roadkill, nomadic settlements near watering holes (the oryx's dry-season feeding places), and introduction of cattle and firearms for easy hunting have also reduced numbers.The IUCN lists the scimitar oryx as regionally extinct in Algeria, Burkina Faso, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Nigeria, Senegal, Sudan, Tunisia, and the Western Sahara, and has assessed it as EW since 2000. Reports of sightings in Chad and Niger remain unsubstantiated, despite extensive surveys carried out throughout Chad and Niger from 2001 to 2004 in an effort to detect antelopes in the Sahel and the Sahara. At least until 1985, 500 scimitar oryxes were estimated to be surviving in Chad and Niger, but by 1988, only a few individuals survived in the wild.A global captive-breeding program now exists for the scimitar oryx. In 2015, about 1,750 captives were managed as part of breeding programs; at the program's peak, up to 11,000 were kept in Texas farms and 4,000 were held in the Arab states of the Persian Gulf. Reintroduction plans involve fenced-in herds in Bou-Hedma National Park (1985), Sidi Toui National Park (1999) and Oued Dekouk National Park (1999) in Tunisia; Souss-Massa National Park (1995) in Morocco; and Ferlo Faunal Reserve (1998) and Guembeul Wildlife Reserve (1999) in Senegal.Chad is currently leading a project to reintroduce the species in Ouadi Rimé-Ouadi Achim Game Reserve, with the support of the Sahara Conservation Fund and the Environment Agency of Abu Dhabi. At 78,000 km2 – equivalent to the size of Scotland- Ouadi Rimé Ouadi Achim is one of the world's largest protected areas. The first group was released at the beginning of 2016 in an acclimation enclosure and then fully released in the wild in the rainy season. That group was made of 21 animals, which by the beginning of 2017 had already produced a calf, the first birth in the wild for more than 20 years. A second group comprising six males and eight females was placed in the acclimation enclosure on 21 January 2017.The Marwell Zoo in Hampshire and the Edinburgh Zoo have also worked in partnership with ZSL to help reintroduce captive-bred scimitar oryx to their former natural ranges.  The Tunisian reintroductions began in 1985 with 10 scimitar oryx from the Marwell and Edinburgh Zoos (co-ordinated by ZSL). In 1999 and 2007, Marwell co-ordinated the release of scimitar oryx into three more protected areas within their former historic range.
+
+
+== In culture ==
+
+
+=== Ancient times ===
+In ancient Egypt, scimitar oryxes were domesticated and tamed, possibly to be used as offerings for religious ceremonies or as food. They were called ran and bred in captivity. In ancient Rome, they were kept in paddocks and used for coursing, and wealthy Romans ate them. The scimitar oryx was the preferred quarry of Sahelo-Saharan hunters. Its hide is of superior quality, and the king of Rio de Oro sent 1,000 shields made of it to a contemporary in the Middle Ages. Since then, it has been used to make ropes, harnesses, and saddlery.
+
+
+=== Unicorn myth ===
+The myth of the one-horned unicorn may have originated from sightings of injured scimitar oryxes; Aristotle and Pliny the Elder held that the oryx was the unicorn's "prototype". From certain angles, the oryx may seem to have one horn rather than two, and given that its horns are made from hollow bone that cannot be regrown, if a scimitar oryx were to lose one of its horns, for the rest of its life it would have only one.
+
+
+=== Modern times ===
+In 2015, Yellow Nose, a scimitar oryx that lives in Portland, Oregon, escaped and startled hikers in Forest Park. The following day, he was caught and returned home.

+The East African oryx (Oryx beisa), also known as the beisa is a species of antelope from East Africa. It has two subspecies: the common beisa oryx (Oryx beisa beisa) found in steppe and semidesert throughout the Horn of Africa and north of the Tana River, and the fringe-eared oryx (Oryx beisa callotis) south of the Tana River in southern Kenya and parts of Tanzania. In the past, some taxonomists considered it a subspecies of the gemsbok (Oryx gazella), but they are genetically distinct; the diploid chromosome count is 56 for the beisa and 58 for the gemsbok. The species is listed as Endangered by the IUCN.
+
+
+== Description ==
+The East African oryx stands just over a metre at the shoulder and weighs around 175 lb (79 kg). It has a grey coat with a white underside, separated from the grey by a stripe of black, with black stripes where the head attaches to the neck, along the nose, and from the eye to the mouth and on the forehead. The mane is small and chestnut-coloured; the ringed horns are thin and straight. They are found on both sexes and typically measure 75–80 cm (30–31 in). Comparably, the gemsbok has an entirely black tail, a black patch at the base of the tail, and more black on the legs (including a patch on the hindlegs) and lower flanks. The smaller Arabian oryx is overall whiter with largely dark legs.
+
+
+== Behaviour ==
+East African oryx live in semidesert and steppes, where they eat grasses, leaves, fruit and buds. They are able to store water by raising their body temperatures (so as to avoid perspiration). They gather in herds of five to 40 animals, often with females moving at the front and a large male guarding from the rear. Some older males are solitary. Radio tracking studies show the solitary males are often accompanied for brief periods by breeding-condition females, so it is probable they are executing a strategy to maximise their chances of reproduction.

+The gemsbok or South African oryx (Oryx gazella) is a large antelope in the genus Oryx. It is native to the extremely dry, arid regions of Southern Africa; notably, the Kalahari Desert. Some authorities formerly classified the East African oryx, or beisa oryx, as a subspecies.
+The gemsbok is depicted on the coat of arms of Namibia, where the current population of the species is estimated at 373,000 individuals. In the town of Oranjemund, resident gemsbok wander freely around the streets, taking advantage of the vegetation in the town, such as the grass in parks, road medians, and browsing on low branches of the many trees.
+
+
+== Name ==
+The name gemsbok is from Afrikaans, which itself is from the Dutch word of the same spelling, meaning "male chamois", composed of gems (“chamois”) + bok (“buck, male goat”). The Dutch gems is further from German Gämse ("chamois"). Although some superficial similarities in appearance (especially in the facial pattern) are noticed, the chamois and the oryx are not closely related. The usual pronunciation in English is .
+
+
+== Description ==
+Gemsbok is light taupe to tan in color, with lighter patches toward the bottom rear of the rump. Their tails are long and black in color. A blackish stripe extends from the chin down the lower edge of the neck, through the juncture of the shoulder and leg along the lower flank of each side to the blackish section of the rear leg. They have muscular necks and shoulders, and their legs have white 'socks' with a black patch on the front of both the front legs, and both sexes have long, straight horns. Comparably, the East African oryx lacks a dark patch at the base of the tail, has less black on the legs (none on the hindlegs), and less black on the lower flanks. One very rare color morph is the "golden oryx", in which the gemsbok's black markings are muted and appear to be golden.
+Gemsbok are the largest species in the genus Oryx. They stand about 1.2 m (3.9 ft) at the shoulder. The body length can vary from 190 to 240 cm (75 to 94 in) and the tail measures 45 to 90 cm (18 to 35 in). Male gemsbok can weigh between 180 and 240 kg (400 and 530 lb), while females weigh 100–210 kg (220–460 lb).
+
+
+=== Horns ===
+
+Gemsbok are widely hunted for their spectacular horns that average 85 cm (33 in) in length.  From a distance, the only outward difference between males and females is their horns, and many hunters mistake females for males each year.  In males horns tend to be thicker with larger bases.  Females have slightly longer, thinner horns.
+Female gemsbok use their horns to defend themselves and their offspring from predators, while males primarily use their horns to defend their territories from other males.Gemsbok are one of the few antelope species where female trophies are sometimes more desirable than male ones. A gemsbok horn can be fashioned into a natural trumpet and, according to some authorities, can be used as a shofar.
+
+
+== Ecology and biology ==
+Gemsbok live in herds of about 10–40 animals, which consist of a dominant male, a few nondominant males, and females. They are mainly desert-dwelling and do not depend on drinking water to supply their physiological needs. They can reach running speeds of up to 60 km/h (37 mph).
+
+
+=== Diet ===
+The gemsbok is generally a grazer but changes to browsing during the dry season or when grass is sparse. It may dig up to a meter deep to find roots and tubers, supplementing its water intake by eating wild tsamma melons and cucumbers, which can provide all the water required (3 liters per 100 kg bodyweight and day).
+
+
+=== Reproduction ===
+
+The gemsbok is polygynous, with one resident male mating with the receptive females in the herd. The male is known to secure exclusive mating access to the females by attempting to herd mixed or nursery herds onto his territory. The gemsbok has no specified breeding season, but the young in a given herd tend to be of a similar age due to reproductive synchrony between females. Pregnant females leave the herd before giving birth. The gestation period lasts 270 days and mothers give birth to 1-2 offspring. The calf remains hidden 6 weeks after birth, after which mother and calf rejoin the herd. The calf is weaned at 3.5 months, becomes independent at 4.5 month, and achieves sexual maturity at 1.5–2 years in both sexes.
+
+
+== Introduction to North America ==
+In 1969, the New Mexico State Department of Game and Fish decided to introduce gemsbok to the Tularosa Basin, New Mexico, in the United States. Ninety-three were released from 1969 to 1977, with the current population estimated to be around 3,000 individuals. As they are capable of year-round breeding, the transplanted population thrives in the absence of their natural predators, such as the lion (Panthera leo), cheetah (Acinonyx jubatus) and leopard (Panthera pardus). Except for calves, the oryx is too large to be preyed on by the cougar (Puma concolor) and most other major American desert carnivores, since the jaguar (Panthera onca) is extirpated from the state, and the reintroduced Mexican wolf (Canis lupus baileyi) is too low in population numbers (and all known Mexican wolf populations are over 100 miles away). The species is therefore primarily managed by regulated hunting. Gradually expanding their range from Tularosa Basin towards the west and northwest, an unknown number of animals are now also established in the San Andres National Wildlife Refuge, the Jornada Biosphere Reserve as well as the endorheic drainage basins east of Caballo Mountains, especially where these are traversed by the Jornada del Muerto trail north of Upham.

+The pheasant pigeon (Otidiphaps nobilis) is a species of large terrestrial pigeon. It is the only species of the monotypic genus Otidiphaps. The pheasant pigeon is found in the primary rainforests of New Guinea and nearby islands. It ranges primarily over hilly and lower mountain areas, but can also be found in lowlands.
+
+
+== Taxonomy and systematics ==
+The genus name makes reference to its similarities to the bustard family (Otidae). Its common name reflects its adaptation to living on the forest floor in the fashion of a South East Asian pheasant.
+
+
+=== Subspecies ===
+Commonly, there are four subspecies recognized that differ primarily in the presence or absence of a small crest and in the colour of the nape:
+White-naped pheasant pigeon (O. n. aruensis) – Rothschild, 1928: Found on the Aru Islands, Vulnerable
+Green-naped pheasant pigeon (O. n. nobilis) – Gould, 1870: Found on western New Guinea, Batanta and Waigeo Islands, Least concern.
+Grey-naped pheasant pigeon (O. n. cervicalis) – Ramsay, EP, 1880: Found on eastern and south-eastern New Guinea, Least concern.
+Black-naped pheasant pigeon (O. n. insularis) – Salvin & Godman, 1883: Found on Fergusson Island, Critically Endangered.Some authors however recognize the four subspecies as four different species, a classification scheme followed by the IUCN.
+
+
+== Description ==
+The pheasant pigeon resembles a pheasant in external morphology, particularly in its laterally compressed tail and rounded wings. They have glossy black heads, undersides, rears and lower backs, and short rounded brown wings, and a white, green, grey, or black nape depending on the subspecies. No galliform birds occur in New Guinea, and the pheasant pigeon has filled the ecological niche of a partridge or small pheasant (while the larger Goura crowned pigeons have a lifestyle similar to larger pheasants, grouse or turkeys). It is a highly secretive species, feeding on seeds and fallen fruits. It nests on the ground below trees and bushes, laying one egg that it incubates for around four weeks. Both adults incubate and look after the young, feeding regurgitated crop milk to their young (a common practice for most pigeons).
+They have a range of calls including a drilling-like sound, a typical pigeon cooing call and a loud "wu-huwoooooa" call that rises and falls in pitch before trailing off at the end.
+They are found in rainforest habitats, eating fallen fruits and seeds, in the Aru Islands. As they avoid human settlements, the little that is known about their behavior comes from observation at zoos.
+
+		
+		
+		
+
+
+== Status and conservation ==
+It is believed that the species is slowly declining due to deforestation of their habitats from pressure for logging and agricultural space. Because it is tied to primary forests, and is unique within the pigeon family, it is considered a genus that requires further investigation and monitoring. The green-naped pheasant pigeon (nominate subspecies) and the grey-naped pheasant pigeon are not considered threatened, but the black-naped pheasant pigeon is considered critically endangered and the white-naped pheasant pigeon is vulnerable. The black-naped pheasant pigeon was for a long time known to science only from the type specimen collected in 1882, but was found on Fergusson Island in late 2022.

+The chimpanzee (Pan troglodytes), also known as simply the chimp, is a species of great ape native to the forest and savannah of tropical Africa. It has four confirmed subspecies and a fifth proposed subspecies. When its close relative the bonobo was more commonly known as the pygmy chimpanzee, this species was often called the common chimpanzee or the robust chimpanzee. The chimpanzee and the bonobo are the only species in the genus Pan. Evidence from fossils and DNA sequencing shows that Pan is a sister taxon to the human lineage and is humans' closest living relative. The chimpanzee is covered in coarse black hair, but has a bare face, fingers, toes, palms of the hands, and soles of the feet. It is larger and more robust than the bonobo, weighing 40–70 kg (88–154 lb) for males and 27–50 kg (60–110 lb) for females and standing 120 to 150 cm (3 ft 11 in to 4 ft 11 in).
+The chimpanzee lives in groups that range in size from 15 to 150 members, although individuals travel and forage in much smaller groups during the day. The species lives in a strict male-dominated hierarchy, where disputes are generally settled without the need for violence. Nearly all chimpanzee populations have been recorded using tools, modifying sticks, rocks, grass and leaves and using them for hunting and acquiring honey, termites, ants, nuts and water. The species has also been found creating sharpened sticks to spear small mammals. Its gestation period is eight months. The infant is weaned at about three years old but usually maintains a close relationship with its mother for several years more.
+The chimpanzee is listed on the IUCN Red List as an endangered species. Between 170,000 and 300,000 individuals are estimated across its range. The biggest threats to the chimpanzee are habitat loss, poaching, and disease. Chimpanzees appear in Western popular culture as stereotyped clown-figures and have featured in entertainments such as chimpanzees' tea parties, circus acts and stage shows. They are sometimes kept as pets, though their strength, aggressiveness, and unpredictability makes them dangerous in this role. Some hundreds have been kept in laboratories for research, especially in America. Many attempts have been made to teach languages such as American Sign Language to chimpanzees, with limited success.
+
+
+== Etymology ==
+The English word chimpanzee is first recorded in 1738. It is derived from Vili ci-mpenze or Tshiluba language chimpenze, with a meaning of "ape". The colloquialism "chimp" was most likely coined some time in the late 1870s. The genus name Pan derives from the Greek god, while the specific name troglodytes was taken from the Troglodytae, a mythical race of cave-dwellers.
+
+
+== Taxonomy and genetics ==
+The first great ape known to Western science in the 17th century was the "orang-outang" (genus Pongo), the local Malay name being recorded in Java by the Dutch physician Jacobus Bontius. In 1641, the Dutch anatomist Nicolaes Tulp applied the name to a chimpanzee or bonobo brought to the Netherlands from Angola. Another Dutch anatomist, Peter Camper, dissected specimens from Central Africa and Southeast Asia in the 1770s, noting the differences between the African and Asian apes. The German naturalist Johann Friedrich Blumenbach classified the chimpanzee as Simia troglodytes by 1775. Another German naturalist, Lorenz Oken, coined the genus Pan in 1816. The bonobo was recognised as distinct from the chimpanzee by 1933.
+
+
+=== Evolution ===
+
+Despite a large number of Homo fossil finds, Pan fossils were not described until 2005. Existing chimpanzee populations in West and Central Africa do not overlap with the major human fossil sites in East Africa, but chimpanzee fossils have now been reported from Kenya. This indicates that both humans and members of the Pan clade were present in the East African Rift Valley during the Middle Pleistocene.DNA evidence suggests the bonobo and chimpanzee species separated from each other less than one million years ago (similar in relation between Homo sapiens and Neanderthals). A 2017 genetic study suggests ancient gene flow (introgression) between 200 and 550 thousand years ago from the bonobo into the ancestors of central and eastern chimpanzees. The chimpanzee line split from the last common ancestor of the human line around six million years ago. Because no species other than Homo sapiens has survived from the human line of that branching, both chimpanzee species are the closest living relatives of humans; the lineage of humans and chimpanzees diverged from gorillas (genus Gorilla) about seven million years ago. A 2003 study argues the chimpanzee should be included in the human branch as Homo troglodytes and notes "experts say many scientists are likely to resist the reclassification, especially in the emotionally-charged and often disputed field of anthropology".
+
+
+=== Subspecies and population status ===
+
+Four subspecies of the chimpanzee have been recognised, with the possibility of a fifth:
+Central chimpanzee or the tschego (Pan troglodytes troglodytes), found in Cameroon, the Central African Republic, Equatorial Guinea, Gabon, the Republic of the Congo, and the Democratic Republic of the Congo, with about 140,000 individuals existing in the wild.
+Western chimpanzee (P. troglodytes verus), found in Ivory Coast, Guinea, Liberia, Mali, Sierra Leone, Guinea-Bissau, Senegal, and Ghana with about 52,800 individuals still in existence.
+Nigeria-Cameroon chimpanzee (P. troglodytes ellioti (also known as P. t. vellerosus)), that live within forested areas across Nigeria and Cameroon, with 6000–9000 individuals still in existence.
+Eastern chimpanzee (P. troglodytes schweinfurthii), found in the Central African Republic, South Sudan, the Democratic Republic of the Congo, Uganda, Rwanda, Burundi, Tanzania, and Zambia, with approximately 180,000–256,000 individuals still existing in the wild.
+Southeastern chimpanzee, P. troglodytes marungensis, in Burundi, Rwanda, Tanzania, and Uganda. Colin Groves argues that this is a subspecies, created by enough variation between the northern and southern populations of P. t. schweinfurthii, but it is not recognised by the IUCN.
+
+
+=== Genome ===
+
+A draft version of the chimpanzee genome was published in 2005 and encodes 18,759 proteins, (compared to 20,383 in the human proteome). The DNA sequences of humans and chimpanzees are very similar and the difference in protein number mostly arises from incomplete sequences in the chimp genome. Both species differ by about 35 million single-nucleotide changes, five million insertion/deletion events and various chromosomal rearrangements. Typical human and chimpanzee protein homologs differ in an average of only two amino acids. About 30% of all human proteins are identical in sequence to the corresponding chimpanzee protein. Duplications of small parts of chromosomes have been the major source of differences between human and chimpanzee genetic material; about 2.7% of the corresponding modern genomes represent differences, produced by gene duplications or deletions, since humans and chimpanzees diverged from their common evolutionary ancestor.
+
+
+== Characteristics ==
+
+Adult chimpanzees have an average standing height of 150 cm (4 ft 11 in). Wild adult males weigh between 40 and 70 kg (88 and 154 lb) with females weighing between 27 and 50 kg (60 and 110 lb). In exceptional cases, certain individuals may considerably exceed these measurements, standing over 168 cm (5 ft 6 in) on two legs and weighing up to 136 kg (300 lb) in captivity.The chimpanzee is more robustly built than the bonobo but less than the gorilla. The arms of a chimpanzee are longer than its legs and can reach below the knees. The hands have long fingers with short thumbs and flat fingernails. The feet are adapted for grasping, and the big toe is opposable. The pelvis is long with an extended ilium. A chimpanzee's head is rounded with a prominent and prognathous face and a pronounced brow ridge. It has forward-facing eyes, a small nose, rounded non-lobed ears, a long mobile upper lip. Additionally, adult males have sharp canine teeth. Chimpanzees lack the prominent sagittal crest and associated head and neck musculature of gorillas.Chimpanzee bodies are covered by coarse hair, except for the face, fingers, toes, palms of the hands, and soles of the feet. Chimpanzees lose more hair as they age and develop bald spots. The hair of a chimpanzee is typically black but can be brown or ginger. As they get older, white or grey patches may appear, particularly on the chin and lower region. The skin may range from pale to dark, though females develop swelling pink skin when in oestrus.Chimpanzees are adapted for both arboreal and terrestrial locomotion. Arboreal locomotion consists of vertical climbing and brachiation. On the ground, chimpanzees move both quadrupedally and bipedally. These movements appear to have similar energy costs. As with bonobos and gorillas, chimpanzees move quadrupedally by knuckle-walking, which probably evolved independently in Pan and Gorilla. The physical strength of chimps is around 1.5 times greater than humans due to higher content of fast twitch muscle fibres, one of the chimpanzee's adaptations for climbing and swinging. According to Japan's Asahiyama Zoo, the grip strength of an adult chimpanzee is estimated to be 200 kg (441 lb), while other sources claim figures of up to 330 kg (727 lb).
+
+
+== Ecology ==
+
+The chimpanzee is a highly adaptable species. It lives in a variety of habitats, including dry savanna, evergreen rainforest, montane forest, swamp forest, and dry woodland-savanna mosaic. In Gombe, the chimpanzee mostly uses semideciduous and evergreen forest as well as open woodland. At Bossou, the chimpanzee inhabits multistage secondary deciduous forest, which has grown after shifting cultivation, as well as primary forest and grassland. At Taï, it is found in the last remaining tropical rain forest in Ivory Coast. The chimpanzee has an advanced cognitive map of its home range and can repeatedly find food. The chimpanzee builds a sleeping nest in a tree in a different location each night, never using the same nest more than once. Chimpanzees sleep alone in separate nests except for infants or juvenile chimpanzees, which sleep with their mothers.
+
+
+=== Diet ===
+
+The chimpanzee is an omnivorous frugivore. It prefers fruit above all other food items but also eats leaves, leaf buds, seeds, blossoms, stems, pith, bark, and resin. A study in Budongo Forest, Uganda found that 64.5% of their feeding time concentrated on fruits (84.6% of which being ripe), particularly those from two species of Ficus, Maesopsis eminii, and Celtis durandii. In addition, 19% of feeding time was spent on arboreal leaves, mostly Broussonetia papyrifera and Celtis mildbraedii. While the chimpanzee is mostly herbivorous, it does eat honey, soil, insects, birds and their eggs, and small to medium-sized mammals, including other primates. Insect species consumed include the weaver ant Oecophylla longinoda, Macrotermes termites, and honey bees. The red colobus ranks at the top of preferred mammal prey. Other mammalian prey include red-tailed monkeys, infant and juvenile yellow baboons, bush babies, blue duikers, bushbucks, and common warthogs.Despite the fact that chimpanzees are known to hunt and to collect both insects and other invertebrates, such food actually makes up a very small portion of their diet, from as little as 2% yearly to as much as 65 grams of animal flesh per day for each adult chimpanzee in peak hunting seasons. This also varies from troop to troop and year to year. However, in all cases, the majority of their diet consists of fruits, leaves, roots, and other plant matter. Female chimpanzees appear to consume much less animal flesh than males, according to several studies. Jane Goodall documented many occasions within Gombe Stream National Park of chimpanzees and western red colobus monkeys ignoring each other despite close proximity.Chimpanzees do not appear to directly compete with gorillas in areas where they overlap. When fruit is abundant, gorilla and chimpanzee diets converge, but when fruit is scarce gorillas resort to vegetation. The two apes may also feed on different species, whether fruit or insects. Chimpanzees and gorillas usually ignore or avoid each other when feeding on the same tree, but coalitions of chimpanzees have been observed attacking families of gorillas including silverbacks and killing infants.
+
+
+=== Mortality and health ===
+
+The average lifespan of a chimpanzee in the wild is relatively short, usually less than 15 years, although individuals that reach 12 years may live an additional 15 years. On rare occasions, wild chimpanzees may live nearly 60 years. Captive chimpanzees tend to live longer than most wild ones, with median lifespans of 31.7 years for males and 38.7 years for females. The oldest known male captive chimpanzee to have been documented lived to 66 years, and the oldest female, Little Mama, was over 70 years old.Leopards prey on chimpanzees in some areas. It is possible that much of the mortality caused by leopards can be attributed to individuals that have specialised in chimp-killing. Chimpanzees may react to a leopard's presence with loud vocalising, branch shaking, and throwing objects. There is at least one record of chimpanzees killing a leopard cub after mobbing it and its mother in their den. Four chimpanzees could have fallen prey to lions at Mahale Mountains National Park. Although no other instances of lion predation on chimpanzees have been recorded, lions likely do kill chimpanzees occasionally, and the larger group sizes of savanna chimpanzees may have developed as a response to threats from these big cats. Chimpanzees may react to lions by fleeing up trees, vocalising, or hiding in silence.
+
+Chimpanzees and humans share only 50% of their parasite and microbe species. This is due to the differences in environmental and dietary adaptations; human internal parasite species overlap more with omnivorous, savanna-dwelling baboons. The chimpanzee is host to the louse species Pediculus schaeffi, a close relative of P. humanus, which infests human head and body hair. By contrast, the human pubic louse Pthirus pubis is closely related to Pthirus gorillae, which infests gorillas. A 2017 study of gastrointestinal parasites of wild chimpanzees in degraded forest in Uganda found nine species of protozoa, five nematodes, one cestode, and one trematode. The most prevalent species was the protozoan Troglodytella abrassarti.
+
+
+== Behaviour ==
+Recent studies have suggested that human observers influence chimpanzee behaviour. One suggestion is that drones, camera traps, and remote microphones should be used to record and monitor chimpanzees rather than direct human observation.
+
+
+=== Group structure ===
+
+Chimpanzees live in communities that typically range from around 20 to more than 150 members but spend most of their time traveling in small, temporary groups consisting of a few individuals. These groups may consist of any combination of age and sexes. Both males and females sometimes travel alone. This fission-fusion society may include groups of four types: all-male, adult females and offspring, adults of both sexes, or one female and her offspring. These smaller groups emerge in a variety of types, for a variety of purposes. For example, an all-male troop may be organised to hunt for meat, while a group consisting of lactating females serves to act as a "nursery group" for the young.At the core of social structures are males, which patrol the territory, protect group members, and search for food. Males remain in their natal communities, while females generally emigrate at adolescence. Males in a community are more likely to be related to one another than females are to each other. Among males, there is generally a dominance hierarchy, and males are dominant over females. However, this unusual fission-fusion social structure, "in which portions of the parent group may on a regular basis separate from and then rejoin the rest," is highly variable in terms of which particular individual chimpanzees congregate at a given time. This is caused mainly by the large measure of individual autonomy that individuals have within their fission-fusion social groups. As a result, individual chimpanzees often forage for food alone, or in smaller groups, as opposed to the much larger "parent" group, which encompasses all the chimpanzees which regularly come into contact with each other and congregate into parties in a particular area.
+
+Male chimpanzees exist in a linear dominance hierarchy. Top-ranking males tend to be aggressive even during dominance stability. This is probably due to the chimpanzee's fission-fusion society, with male chimpanzees leaving groups and returning after extended periods of time. With this, a dominant male is unsure if any "political maneuvering" has occurred in his absence and must re-establish his dominance. Thus, a large amount of aggression occurs within five to fifteen minutes after a reunion. During these encounters, displays of aggression are generally preferred over physical attacks.Males maintain and improve their social ranks by forming coalitions, which have been characterised as "exploitative" and based on an individual's influence in agonistic interactions. Being in a coalition allows males to dominate a third individual when they could not by themselves, as politically apt chimpanzees can exert power over aggressive interactions regardless of their rank. Coalitions can also give an individual male the confidence to challenge a dominant or larger male. The more allies a male has, the better his chance of becoming dominant. However, most changes in hierarchical rank are caused by dyadic interactions. Chimpanzee alliances can be very fickle, and one member may suddenly turn on another if it is to his advantage.
+
+Low-ranking males frequently switch sides in disputes between more dominant individuals. Low-ranking males benefit from an unstable hierarchy and often find increased sexual opportunities if a dispute or conflict occurs. In addition, conflicts between dominant males cause them to focus on each other rather than the lower-ranking males. Social hierarchies among adult females tend to be weaker. Nevertheless, the status of an adult female may be important for her offspring. Females in Taï have also been recorded to form alliances. While chimpanzee social structure is often referred to as patriarchal, it is not entirely unheard of for females to forge coalitions against males. There is also at least one recorded case of females securing a dominant position over males in their respective troop, albeit in a captive environment. Social grooming appears to be important in the formation and maintenance of coalitions. It is more common among adult males than either between adult females or between males and females.Chimpanzees have been described as highly territorial and will frequently kill other chimpanzees, although Margaret Power wrote in her 1991 book The Egalitarians that the field studies from which the aggressive data came, Gombe and Mahale, used artificial feeding systems that increased aggression in the chimpanzee populations studied. Thus, the behaviour may not reflect innate characteristics of the species as a whole. In the years following her artificial feeding conditions at Gombe, Jane Goodall described groups of male chimpanzees patrolling the borders of their territory, brutally attacking chimpanzees that had split off from the Gombe group. A study published in 2010 found that the chimpanzees wage wars over territory, not mates. Patrols from smaller groups are more likely to avoid contact with their neighbours. Patrols from large groups even take over a smaller group's territory, gaining access to more resources, food, and females. While it was traditionally accepted that only female chimpanzees immigrate and males remain in their natal troop for life, there are confirmed cases of adult males safely integrating themselves into new communities among West African chimpanzees, suggesting they are less territorial than other subspecies.
+
+
+=== Mating and parenting ===
+
+Chimpanzees mate throughout the year, although the number of females in oestrus varies seasonally in a group. Female chimpanzees are more likely to come into oestrus when food is readily available. Oestrous females exhibit sexual swellings. Chimpanzees are promiscuous: during oestrus, females mate with several males in their community, while males have large testicles for sperm competition. Other forms of mating also exist. A community's dominant males sometimes restrict reproductive access to females. A male and female can form a consortship and mate outside their community. In addition, females sometimes leave their community and mate with males from neighboring communities.These alternative mating strategies give females more mating opportunities without losing the support of the males in their community. Infanticide has been recorded in chimpanzee communities in some areas, and the victims are often consumed. Male chimpanzees practice infanticide on unrelated young to shorten the interbirth intervals in the females. Females sometimes practice infanticide. This may be related to the dominance hierarchy in females or may simply be pathological.Copulation is brief, lasting approximately seven seconds. The gestation period is eight months. Care for the young is provided mostly by their mothers. The survival and emotional health of the young is dependent on maternal care. Mothers provide their young with food, warmth, and protection, and teach them certain skills. In addition, a chimpanzee's future rank may be dependent on its mother's status. Newborn chimpanzees are helpless. For example, their grasping reflex is not strong enough to support them for more than a few seconds. For their first 30 days, infants cling to their mother's bellies. Infants are unable to support their own weight for their first two months and need their mothers' support.When they reach five to six months, infants ride on their mothers' backs. They remain in continual contact for the rest of their first year. When they reach two years of age, they are able to move and sit independently and start moving beyond the arms' reach of their mothers. By four to six years, chimpanzees are weaned and infancy ends. The juvenile period for chimpanzees lasts from their sixth to ninth years. Juveniles remain close to their mothers, but interact an increasing amount with other members of their community. Adolescent females move between groups and are supported by their mothers in agonistic encounters. Adolescent males spend time with adult males in social activities like hunting and boundary patrolling. A captive study suggests males can safely immigrate to a new group if accompanied by immigrant females who have an existing relationship with this male. This gives the resident males reproductive advantages with these females, as they are more inclined to remain in the group if their male friend is also accepted.
+
+
+=== Communication ===
+
+Chimpanzees use facial expressions, postures, and sounds to communicate with each other. Chimpanzees have expressive faces that are important in close-up communications. When frightened, a "full closed grin" causes nearby individuals to be fearful, as well. Playful chimpanzees display an open-mouthed grin. Chimpanzees may also express themselves with the "pout", which is made in distress, the "sneer", which is made when threatening or fearful, and "compressed-lips face", which is a type of display. When submitting to a dominant individual, a chimpanzee crunches, bobs, and extends a hand. When in an aggressive mode, a chimpanzee swaggers bipedally, hunched over and arms waving, in an attempt to exaggerate its size. While travelling, chimpanzees keep in contact by beating their hands and feet against the trunks of large trees, an act that is known as "drumming". They also do this when encountering individuals from other communities.Vocalisations are also important in chimpanzee communication. The most common call in adults is the "pant-hoot", which may signal social rank and bond along with keeping groups together. Pant-hoots are made of four parts, starting with soft "hoos", the introduction; that gets louder and louder, the build-up; and climax into screams and sometimes barks; these die down back to soft "hoos" during the letdown phase as the call ends. Grunting is made in situations like feeding and greeting. Submissive individuals make "pant-grunts" towards their superiors. Whimpering is made by young chimpanzees as a form of begging or when lost from the group. Chimpanzees use distance calls to draw attention to danger, food sources, or other community members. "Barks" may be made as "short barks" when hunting and "tonal barks" when sighting large snakes.
+
+
+=== Hunting ===
+When hunting small monkeys such as the red colobus, chimpanzees hunt where the forest canopy is interrupted or irregular. This allows them to easily corner the monkeys when chasing them in the appropriate direction. Chimpanzees may also hunt as a coordinated team, so that they can corner their prey even in a continuous canopy. During an arboreal hunt, each chimpanzee in the hunting groups has a role. "Drivers" serve to keep the prey running in a certain direction and follow them without attempting to make a catch. "Blockers" are stationed at the bottom of the trees and climb up to block prey that takes off in a different direction. "Chasers" move quickly and try to make a catch. Finally, "ambushers" hide and rush out when a monkey nears. While both adults and infants are taken, adult male colobus monkeys will attack the hunting chimps. Male chimpanzees hunt more than females. When caught and killed, the meal is distributed to all hunting party members and even bystanders.
+
+
+== Intelligence and cognition ==
+
+Chimpanzees display numerous signs of intelligence, from the ability to remember symbols to cooperation, tool use, and perhaps language. They are among species that have passed the mirror test, suggesting self-awareness. In one study, two young chimpanzees showed retention of mirror self-recognition after one year without access to mirrors. Chimpanzees have been observed to use insects to treat their own wounds and those of others. They catch them and apply them directly to the injury. Chimpanzees also display signs of culture among groups, with the learning and transmission of variations in grooming, tool use and foraging techniques leading to localized traditions.A 30-year study at Kyoto University's Primate Research Institute has shown that chimpanzees are able to learn to recognise the numbers 1 to 9 and their values. The chimpanzees further show an aptitude for eidetic memory, demonstrated in experiments in which the jumbled digits are flashed onto a computer screen for less than a quarter of a second. One chimpanzee, Ayumu, was able to correctly and quickly point to the positions where they appeared in ascending order. Ayumu performed better than human adults who were given the same test.In controlled experiments on cooperation, chimpanzees show a basic understanding of cooperation, and recruit the best collaborators. In a group setting with a device that delivered food rewards only to cooperating chimpanzees, cooperation first increased, then, due to competitive behaviour, decreased, before finally increasing to the highest level through punishment and other arbitrage behaviours.Great apes show laughter-like vocalisations in response to physical contact, such as wrestling, play chasing, or tickling. This is documented in wild and captive chimpanzees. Chimpanzee laughter is not readily recognisable to humans as such, because it is generated by alternating inhalations and exhalations that sound more like breathing and panting. Instances in which nonhuman primates have expressed joy have been reported. Humans and chimpanzees share similar ticklish areas of the body, such as the armpits and belly. The enjoyment of tickling in chimpanzees does not diminish with age.Chimpanzees have displayed different behaviours in response to a dying or dead group member. When witnessing a sudden death, the other group members act in frenzy, with vocalisations, aggressive displays, and touching of the corpse. In one case chimpanzees cared for a dying elder, then attended and cleaned the corpse. Afterward, they avoided the spot where the elder died and behaved in a more subdued manner. Mothers have been reported to carry around and groom their dead infants for several days.Experimenters now and then witness behaviour that cannot be readily reconciled with chimpanzee intelligence or theory of mind. Wolfgang Köhler, for instance, reported insightful behaviour in chimpanzees, but he likewise often observed that they experienced "special difficulty" in solving simple problems. Researchers also reported that, when faced with a choice between two persons, chimpanzees were just as likely to beg food from a person who could see the begging gesture as from a person who could not, thereby raising the possibility that chimpanzees lack theory of mind.
+
+
+=== Tool use ===
+
+Nearly all chimpanzee populations have been recorded using tools. They modify sticks, rocks, grass, and leaves and use them when foraging for termites and ants, nuts, honey, algae or water. Despite the lack of complexity, forethought and skill are apparent in making these tools. Chimpanzees have used stone tools since at least 4,300 years ago.A chimpanzee from the Kasakela chimpanzee community was the first nonhuman animal reported making a tool, by modifying a twig to use as an instrument for extracting termites from their mound. At Taï, chimpanzees simply use their hands to extract termites. When foraging for honey, chimpanzees use modified short sticks to scoop the honey out of the hive if the bees are stingless. For hives of the dangerous African honeybees, chimpanzees use longer and thinner sticks to extract the honey.Chimpanzees also fish for ants using the same tactic. Ant dipping is difficult and some chimpanzees never master it. West African chimpanzees crack open hard nuts with stones or branches. Some forethought in this activity is apparent, as these tools are not found together or where the nuts are collected. Nut cracking is also difficult and must be learned. Chimpanzees also use leaves as sponges or spoons to drink water.West African chimpanzees in Senegal were found to sharpen sticks with their teeth, which were then used to spear Senegal bushbabies out of small holes in trees. An eastern chimpanzee has been observed using a modified branch as a tool to capture a squirrel.Whilst experimental studies on captive chimpanzees have found that many of their species-typical tool-use behaviours can be individually learnt by each chimpanzees, a 2021 study on their abilities to make and use stone flakes, in a similar way as hypothesised for early hominins, did not find this behaviour across two populations of chimpanzees - suggesting that this behaviour is outside the chimpanzee species-typical range.
+
+
+=== Language ===
+
+Scientists have attempted to teach human language to several species of great ape. One early attempt by Allen and Beatrix Gardner in the 1960s involved spending 51 months teaching American Sign Language to a chimpanzee named Washoe. The Gardners reported that Washoe learned 151 signs, and had spontaneously taught them to other chimpanzees, including her adopted son, Loulis. Over a longer period of time, Washoe was reported to have learned over 350 signs.Debate is ongoing among scientists such as David Premack about chimpanzees' ability to learn language. Since the early reports on Washoe, numerous other studies have been conducted, with varying levels of success. One involved a chimpanzee jokingly named Nim Chimpsky (in allusion to the theorist of language Noam Chomsky), trained by Herbert Terrace of Columbia University. Although his initial reports were quite positive, in November 1979, Terrace and his team, including psycholinguist Thomas Bever, re-evaluated the videotapes of Nim with his trainers, analyzing them frame by frame for signs, as well as for exact context (what was happening both before and after Nim's signs). In the reanalysis, Terrace and Bever concluded that Nim's utterances could be explained merely as prompting on the part of the experimenters, as well as mistakes in reporting the data. "Much of the apes' behaviour is pure drill", he said. "Language still stands as an important definition of the human species." In this reversal, Terrace now argued Nim's use of ASL was not like human language acquisition. Nim never initiated conversations himself, rarely introduced new words, and mostly imitated what the humans did. More importantly, Nim's word strings varied in their ordering, suggesting that he was incapable of syntax. Nim's sentences also did not grow in length, unlike human children whose vocabulary and sentence length show a strong positive correlation.

+
+== Relations with humans ==
+
+
+=== In culture ===
+
+Chimpanzees are rarely represented in African culture, as people find their resemblance to humans discomforting. The Gio people of Liberia and the Hemba people of the Congo have created masks of the animals. Gio masks are crude and blocky, and worn when teaching young people how not to behave. The Hemba masks have a smile that suggests drunken anger, insanity or horror and are worn during rituals at funerals, representing the "awful reality of death". The masks may also serve to guard households and protect both human and plant fertility. Stories have been told of chimpanzees kidnapping and raping women.In Western popular culture, chimpanzees have occasionally been stereotyped as childlike companions, sidekicks or clowns. They are especially suited for the latter role on account of their prominent facial features, long limbs and fast movements, which humans often find amusing. Accordingly, entertainment acts featuring chimpanzees dressed up as humans with lip-synchronised human voices have been traditional staples of circuses, stage shows and TV shows like Lancelot Link, Secret Chimp (1970-1972) and The Chimp Channel (1999). From 1926 until 1972, London Zoo, followed by several other zoos around the world, held a chimpanzees' tea party daily, inspiring a long-running series of advertisements for PG Tips tea featuring such a party. Animal rights groups have urged a stop to such acts, considering them abusive.
+
+Chimpanzees in media include Judy on the television series Daktari in the 1960s and Darwin on The Wild Thornberrys in the 1990s. In contrast to the fictional depictions of other animals, such as dogs (as in Lassie), dolphins (Flipper), horses (The Black Stallion) or even other great apes (King Kong), chimpanzee characters and actions are rarely relevant to the plot. Depictions of chimpanzees as individuals rather than stock characters, and as central rather than incidental to the plot can be found in science fiction. Robert A. Heinlein's 1947 short story "Jerry Was a Man" concerns a genetically enhanced chimpanzee suing for better treatment. The 1972 film Conquest of the Planet of the Apes, the third sequel of the 1968 film Planet of the Apes, portrays a futuristic revolt of enslaved apes led by the only talking chimpanzee, Caesar, against their human masters.
+
+
+=== As pets ===
+Chimpanzees have traditionally been kept as pets in a few African villages, especially in the Democratic Republic of Congo. In Virunga National Park in the east of the country, the park authorities regularly confiscate chimpanzees from people keeping them as pets. Outside their range, chimpanzees are popular as exotic pets despite their strength and aggression. Even where keeping non-human primates as pets is illegal, the exotic pet trade continues to prosper, leading to injuries from attacks.
+
+
+=== Use in research ===
+
+Hundreds of chimpanzees have been kept in laboratories for research. Most such laboratories either conduct or make the animals available for invasive research, defined as "inoculation with an infectious agent, surgery or biopsy conducted for the sake of research and not for the sake of the chimpanzee, and/or drug testing". Research chimpanzees tend to be used repeatedly over decades for up to 40 years, unlike the pattern of use of most laboratory animals. Two federally funded American laboratories use chimpanzees: the Yerkes National Primate Research Center at Emory University in Atlanta, Georgia, and the Southwest National Primate Center in San Antonio, Texas. Five hundred chimpanzees have been retired from laboratory use in the U.S. and live in animal sanctuaries in the U.S. or Canada.A five-year moratorium was imposed by the US National Institutes of Health in 1996, because too many chimpanzees had been bred for HIV research, and it has been extended annually since 2001. With the publication of the chimpanzee genome, plans to increase the use of chimpanzees in America were reportedly increasing in 2006, some scientists arguing that the federal moratorium on breeding chimpanzees for research should be lifted. However, in 2007, the NIH made the moratorium permanent.
+
+Other researchers argue that chimpanzees either should not be used in research, or should be treated differently, for instance with legal status as persons. Pascal Gagneux, an evolutionary biologist and primate expert at the University of California, San Diego, argues, given chimpanzees' sense of self, tool use, and genetic similarity to human beings, studies using chimpanzees should follow the ethical guidelines used for human subjects unable to give consent. A recent study suggests chimpanzees which are retired from labs exhibit a form of posttraumatic stress disorder. Stuart Zola, director of the Yerkes laboratory, disagrees. He told National Geographic: "I don't think we should make a distinction between our obligation to treat humanely any species, whether it's a rat or a monkey or a chimpanzee. No matter how much we may wish it, chimps are not human."Only one European laboratory, the Biomedical Primate Research Centre in Rijswijk, the Netherlands, used chimpanzees in research. It formerly held 108 chimpanzees among 1,300 non-human primates. The Dutch ministry of science decided to phase out research at the centre from 2001. Trials already under way were however allowed to run their course. Chimpanzees including the female Ai have been studied at the Primate Research Institute of Kyoto University, Japan, formerly directed by Tetsuro Matsuzawa, since 1978. Some 12 chimpanzees are currently held at the facility.Two chimpanzees have been sent into outer space as NASA research subjects. Ham, the first great ape in space, was launched in the Mercury-Redstone 2 capsule on 31 January 1961, and survived the suborbital flight. Enos, the third primate to orbit Earth after Soviet cosmonauts Yuri Gagarin and Gherman Titov, flew on Mercury-Atlas 5 on 29 November of the same year.
+
+
+=== Field study ===
+
+Jane Goodall undertook the first long-term field study of the chimpanzee, begun in Tanzania at Gombe Stream National Park in 1960. Other long-term studies begun in the 1960s include A. Kortlandt's in the eastern Democratic Republic of the Congo and Toshisada Nishida's in Mahale Mountains National Park in Tanzania. Current understanding of the species' typical behaviours and social organisation has been formed largely from Goodall's ongoing 60-year Gombe research study.
+
+
+=== Attacks ===
+Chimpanzees have attacked humans. In Uganda, several attacks on children have happened, some of them fatal. Some of these attacks may have been due to the chimpanzees being intoxicated (from alcohol obtained from rural brewing operations) and becoming aggressive towards humans. Human interactions with chimpanzees may be especially dangerous if the chimpanzees perceive humans as potential rivals. At least six cases of chimpanzees snatching and eating human babies are documented.A chimpanzee's strength and sharp teeth mean that attacks, even on adult humans, can cause severe injuries. This was evident after the attack and near death of former NASCAR driver St. James Davis, who was mauled by two escaped chimpanzees while he and his wife were celebrating the birthday of their former pet chimpanzee. Another example of chimpanzees being aggressive toward humans occurred in 2009 in Stamford, Connecticut, when a 90-kilogram (200 lb), 13-year-old pet chimpanzee named Travis attacked his owner's friend, who lost her hands, eyes, nose, and part of her maxilla from the attack.
+
+
+=== Human immunodeficiency virus ===
+Two primary classes of human immunodeficiency virus (HIV) infect humans: HIV-1 and HIV-2. HIV-1 is the more virulent and easily transmitted, and is the source of the majority of HIV infections throughout the world; HIV-2 is largely confined to west Africa. Both types originated in west and central Africa, jumping from other primates to humans. HIV-1 has evolved from a simian immunodeficiency virus (SIVcpz) found in the subspecies P. t. troglodytes of southern Cameroon. Kinshasa, in the Democratic Republic of Congo, has the greatest genetic diversity of HIV-1 so far discovered, suggesting the virus has been there longer than anywhere else. HIV-2 crossed species from a different strain of HIV, found in the sooty mangabey monkeys in Guinea-Bissau.
+
+
+=== Status and conservation ===
+
+The chimpanzee is on the IUCN Red List as an endangered species. Chimpanzees are legally protected in most of their range and are found both in and outside national parks. Between 172,700 and 299,700 individuals are thought to be living in the wild, a decrease from about a million chimpanzees in the early 1900s. Chimpanzees are listed in Appendix I of the Convention on International Trade in Endangered Species (CITES), meaning that commercial international trade in wild-sourced specimens is prohibited and all other international trade (including in parts and derivatives) is regulated by the CITES permitting system.The biggest threats to the chimpanzee are habitat destruction, poaching, and disease. Chimpanzee habitats have been limited by deforestation in both West and Central Africa. Road building has caused habitat degradation and fragmentation of chimpanzee populations and may allow poachers more access to areas that had not been seriously affected by humans. Although deforestation rates are low in western Central Africa, selective logging may take place outside national parks.Chimpanzees are a common target for poachers. In Ivory Coast, chimpanzees make up 1–3% of bushmeat sold in urban markets. They are also taken, often illegally, for the pet trade and are hunted for medicinal purposes in some areas. Farmers sometimes kill chimpanzees that threaten their crops; others are unintentionally maimed or killed by snares meant for other animals.Infectious diseases are a main cause of death for chimpanzees. They succumb to many diseases that afflict humans because the two species are so similar. As human populations grow, so does the risk of disease transmission between humans and chimpanzees.

+Panthera leo melanochaita is a lion subspecies in Southern and East Africa. In this part of Africa, lion populations are regionally extinct in Lesotho, Djibouti and Eritrea, and are threatened by loss of habitat and prey base, killing by local people in retaliation for loss of livestock, and in several countries also by trophy hunting. Since the turn of the 21st century, lion populations in intensively managed protected areas in Botswana, Namibia, South Africa and Zimbabwe have increased, but declined in East African range countries. In 2005, a Lion Conservation Strategy was developed for East and Southern Africa.Results of a phylogeographic study indicate that lion populations in southern and eastern Africa are forming a major clade distinct from lion populations in West Africa, Central Africa and Asia. In 2017, the Cat Classification Task Force of the IUCN Cat Specialist Group subsumed lion populations according to the major clades into two subspecies, namely P. l. leo and P. l. melanochaita. Within P. l. melanochaita three subclades are clearly distinguishable. One from northeastern Africa, another one from southwestern Africa and a third one from southeastern Africa.The type specimen for P. l. melanochaita was a black-maned lion from the Cape of Good Hope, known as the Cape lion. Phylogeographic analysis of lion samples from Gabon and the Republic of the Congo indicate their close genetic relation to P. l. melanochaita samples from Namibia and Botswana. It has been referred to as the Southern lion, Southern African lion and the 'southern subspecies'.
+
+
+== Taxonomy ==
+
+Felis (Leo) melanochaitus was the scientific name proposed by Charles Hamilton Smith in 1842 who described a lion specimen from South Africa's Cape Province. In the 19th and 20th centuries, several naturalists described zoological specimens from Southern and East Africa and proposed the following subspecies:
+
+Felis leo somaliensis (Noack 1891), based on two lion specimens from Somalia
+Felis leo massaicus (Neumann 1900), based on two lions killed near Kibaya and the Gurui River in Kenya
+Felis leo sabakiensis (Lönnberg 1910), based on two male lions from the environs of Mount Kilimanjaro
+Felis leo roosevelti (Heller 1913), a lion from the Ethiopian Highlands presented to Theodore Roosevelt
+Felis leo nyanzae (Heller 1913), a lion skin from Kampala, Uganda
+Felis leo bleyenberghi (Lönnberg 1914), a male lion from the Katanga Province of Belgian Congo
+Leo leo hollisteri (Joel Asaph Allen 1924), a male lion from the area of Lime Springs, Sotik on the eastern shore of Lake Victoria
+Leo leo krugeri (Austin Roberts 1929), an adult male lion from the Sabi Sand Game Reserve named in honour of Paul Kruger
+Leo leo vernayi (Roberts 1948), a male lion from the Kalahari collected by the Vernay-Lang Kalahari Expedition
+Panthera leo webbensies Ludwig Zukowsky 1964, two lions from Somalia, one in the Natural History Museum, Vienna that originated in Webi Shabeelle, the other kept in a German zoo that had been imported from the hinterland of Mogadishu. 
+Dispute over the validity of these purported subspecies continued among naturalists and curators of natural history museums until the early 21st century.
+In the 20th century, some authors supported the view of the Cape lion being a distinct subspecies. In 1939, the American zoologist Allen also recognized F. l. bleyenberghi, F. l. krugeri and F. l. vernayi as valid subspecies in Southern Africa, and F. l. hollisteri, F. l. nyanzae and F. l. massaica as valid subspecies in East Africa.Pocock subordinated the lion to the genus Panthera in 1930, when he wrote about Asiatic lions. Ellerman and Morrison-Scott recognized only two lion subspecies in the Palearctic realm, namely the African P. l. leo and the Asiatic P. l. persica. Various authors recognized between seven and 10 African lion subspecies. Others followed the classification proposed by Ellerman and Morrison-Scott, recognizing two subspecies including one in Africa.In the 1970s, the scientific name P. l. vernayi was considered synonymous with P. l. krugeri. In 1975, Vratislav Mazák hypothesized that the Cape lion evolved geographically isolated from other populations by the Great Escarpment. In the early 21st century, Mazák's hypothesis about a geographically isolated evolution of the Cape lion was challenged. Genetic exchanges between populations in the Cape, Kalahari and Transvaal Province regions and farther east are considered having been possible through a corridor between the Great Escarpment and the Indian ocean.In 2005, the authors of Mammal Species of the World recognized P. l. bleyenberghi, P. l. krugeri, P. l. vernayi, P. l. massaica, P. l. hollisteri and P. l. nyanzae as valid taxa. In 2016, IUCN Red List assessors subsumed all African lion populations to P. l. leo. Two lion subspecies are now recognised:
+P. l. melanochaita is understood as comprising lion populations in the contemporary Southern and East African range countries,
+P. l. leo comprises lion populations in North, West and Central Africa and Asia.Genome-wide data of a wild-born historical lion sample from Sudan clustered with P. l. leo in mtDNA-based phylogenies, but with a high affinity to P. l. melanochaita. This result indicates that the taxonomic position of lions in Central Africa may require revision.
+
+
+=== Phylogeny ===
+
+Since the beginning of the 21st century, several phylogenetic studies were conducted to aid clarifying the taxonomic status of lion samples kept in museums and collected in the wild. Scientists analysed between 32 and 480 lion samples from up to 22 countries. Results of genetic analyses indicate that the species comprises two main evolutionary groups, one in Southern and East Africa, and the other in the northern and eastern parts of its historical range. These groups genetically diverged between 50,000 and 200,000 years ago. It was assumed that tropical rainforest and the East African Rift constituted major barriers between the two groups.Lion samples from Gabon's Batéké Plateau National Park and Odzala-Kokoua National Park in Republic of the Congo were found to be genetically closely related to lion samples from Namibia and Botswana.
+A phylogenetic analysis of lion samples from Africa and Asia showed that they shared a common ancestor probably between 98,000 and 52,000 years ago. Samples from West Africa shared alleles with samples from Southern Africa, and samples from Central Africa shared alleles with samples from Asia. This indicates that Central Africa was a melting pot of lion populations after they had become isolated. They possibly migrated through corridors in the Nile Basin during the early Holocene.
+
+
+=== Overlap between subspecies ===
+
+Among six samples of captive lions from Ethiopia, five clustered with samples from East Africa, but one with samples from the Sahel. For a subsequent phylogeographic study, eight wild lion samples from the Ethiopian Highlands were included in the DNA sequencing analysis using 194 lion samples from 22 countries. Four of these samples clustered with samples from Central Africa, and four with samples from East Africa, indicating that the Great Rift Valley, Ethiopia was not a complete barrier to gene flow. Southeastern Ethiopia is therefore considered a genetic admixture zone between Central and East African lions.
+
+
+== Distribution and habitat ==
+
+In East and Southern Africa, lion populations declined in:
+
+In Ethiopia, where lion populations declined since at least the early 20th century due to trophy hunting by Europeans, killing of lions by local people out of fear, for illegal sale of skins and during civil wars. As of 2009, between seven and 23 lions were estimated to live in Nechisar National Park located in the Ethiopian Highlands. This small protected area is encroached by local people and their livestock. In 2012, lions were documented in cloud forest habitat of Kafa Biosphere Reserve.
+Somalia since the early 20th century. Intensive poaching since the 1980s and civil unrest posed a threat to lion persistence.
+Uganda to near extinction in the 20th century. In 2010, the lion population in Uganda was estimated at 408 ± 46 individuals in three protected areas including Queen Elizabeth, Murchison Falls and Kidepo Valley National Parks. Other protected areas in the country probably host less than 10 lions. Lions in Queen Elizabeth National Park form a contiguous population with lions in Virunga National Park.
+Kenya in the 1990s due to poisoning of lions and poaching of lion prey species. At least 108 lions were killed between 2001 and 2006 in the Amboseli−Tsavo West−Tsavo East National Park network. As of 2006, there were an estimated 675 lions in the Tsavo national parks, out of the 2,000 total in Kenya. Between 2004 and 2013, lion guardians around Amboseli National Park identified 65 lions in an area of 3,684 km2 (1,422 sq mi). Lion populations in Kenya and Tanzania are fragmented over 17 patches ranging in size from 86 to 127,515 km2 (33 to 49,234 sq mi).
+Rwanda and Tanzania due to killing of lions during the Rwandan Civil War and ensuing refugee crisis in the 1990s. A small population was present in Rwanda's Akagera National Park, estimated at 35 individuals at most in 2004. Lions were reintroduced to this national park in 2015.
+Malawi and Zambia due to illegal hunting of prey species in protected areas.
+Botswana due to intensive hunting and conversion of natural habitats for settlements since the early 19th century. In Northern Tuli Game Reserve, 19 lions died between 2005 and 2011 due to poaching, trophy hunting and snaring.
+Namibia due to massive killing of lions by farmers since at least the 1970s. In 2010, the small and isolated lion population in the Kalahari was estimated at 683 to 1,397 individuals in three protected areas, the Kgalagadi Transfrontier Park, the Kalahari Gemsbok and Gemsbok National Parks.
+South Africa since the early 19th century in the Natal and Cape Provinces south of the Orange River, where the Cape lion population was eradicated by 1860. A few decades later, lions in the Highveld north of the Orange River were also eradicated. In Transvaal, lions occurred historically in the Highveld as well, but were restricted to eastern Transvaal's Bushveld by the 1970s. Between 2000 and 2004, 34 lions were reintroduced to eight protected areas in the Eastern Cape Province, including Addo Elephant National Park. In Venetia Limpopo Nature Reserve, 18 lions were trophy hunted and 11 euthanized between 2005 and 2011.Contemporary lion distribution and habitat quality in East and Southern Africa was assessed in 2005, and Lion Conservation Units (LCU) mapped. Between 2002 and 2012, educated guesses for size of populations in these LCUs ranged from 33,967 to 32,000 individuals. The LCUs Ruaha−Rungwa, Serengeti−Mara, Tsavo−Mkomazi and Selous in East Africa, as well as Luangwa, Kgalagadi, Okavango−Hwange, Mid−Zambezi, Niassa and Greater Limpopo in Southern Africa are currently considered lion strongholds. These LCUs host more than 500 individuals each, and the population trend is stable there as of 2012.
+
+
+=== North East African clade ===
+
+Lions, which can be grouped into the northeastern clade are found in Somalia, Northern Kenya and Ethiopia, with a larger hybridization zone to the Northern lion subspecies (P. l. leo) in Ethiopia.
+
+
+=== South East African clade ===
+
+Lions, which can be grouped into the southeastern clade are found in Southern Kenya, Western DRC, Tanzania, Mozambique, Malawi, Zambia, southern Namibia and South Africa, with a larger hybridization zone to the southwestern lion clade in the Kruger National Park area (Great Limpopo Transfrontier Park). The classification of lions in Uganda is not clarified, since there were no samples included in the most comprehensive recent study.
+
+
+=== South West African clade ===
+
+Lions, which can be grouped into the southwestern clade are found in Angola, Northern Namibia, Northern Botswana and western Zimbabwe, extending southeast into the Tuli block. a There is a larger hybridization zone to the southeastern clade around the Kruger National Park.
+
+
+== Characteristics ==
+
+The lion's fur varies in colour from light buff to dark brown. It has rounded ears and a black tail tuft.
+
+
+=== Size and weight ===
+Average head-to-body length of male lions is 2.47–2.84 m (8 ft 1 in – 9 ft 4 in) with a weight ranging from 150–225 kg (331–496 lb) averaging 187.5 kg (413 lb) in Southern Africa and 145.4–204.7 kg (321–451 lb) averaging 174.9 kg (386 lb) in East Africa. Females average 83–165 kg (183–364 lb) in Southern Africa and 90–167.8 kg (198–370 lb) in East Africa.
+Males in northern Kruger National Park weighed 200.01 kg (440.9 lb) on average, whereas females weighed 143.52 kg (316.4 lb) on average, and males in southern Kruger National Park weighed 186.55 kg (411.3 lb) on average and females weighed 118.37 kg (261.0 lb), though there was an outbreak of tuberculosis in southern park at the time. 
+Skeletal muscles make up 58.8% of the lion's body weight.The largest known lion measured 3.35 m (11.0 ft) in length and weighed 375 kg (825 lb). An exceptionally heavy male lion near Mount Kenya weighed 272 kg (600 lb). The longest wild lion reportedly was a male shot near Mucusso National Park in southern Angola in 1973. In 1936, a man-eating lion shot in 1936 in eastern Transvaal weighed about 313 kg (690 lb), and was considered to have been one of the heaviest wild lions. In 1963, two lions in Tanzania weighed 320 and 360 kg (700 and 800 lb) after killing several livestock.
+
+
+=== Manes ===
+
+In the 19th and 20th centuries, lion type specimens were described on the basis of their mane size and colour. Mane colour varies from sandy, tawny, isabelline, light reddish yellow to dark brown and black. Mane length varies from short to extending to knee joints and under the belly.
+Lions without a mane were observed in the Tsavo area.Mane development is related to age: older males have more extensive manes than younger ones; manes continue to grow up to the age of four to five years, long after lions become sexually mature. Males living in the Kenyan highlands above elevations of 800 m (2,600 ft) develop heavier manes than lions in the more humid and warmer lowlands of eastern and northern Kenya. Average ambient temperature, nutrition and testosterone influence the colour and size of the mane. Its length is an indicator for age and fighting ability of the lion. In Serengeti National Park, female lions favour males with dense and dark manes as mates.
+
+
+=== White lion ===
+
+White lions have occasionally been encountered in and around South Africa's Kruger National Park and the adjacent Timbavati Private Game Reserve. Their whitish fur is a rare morph caused by a double recessive allele. It has normal pigmentation in eyes and skin. They were removed from the wild in the 1970s, thus decreasing the white lion gene pool. Nevertheless, 17 births have been recorded in five different prides between 2007 and 2015. White lions were selected for breeding in captivity. They have been bred in South African camps for use as trophies to be killed during canned hunts.
+
+
+== Behaviour and ecology ==
+
+In Serengeti National Park, monitoring of lion prides started in 1966.
+Between 1966 and 1972, two observed lion prides comprised between seven and 10 females each. Females had litters once in 23 months on average.
+Litters contained two to three cubs. Of 87 cubs born until 1970, only 12 reached the age of two years. Cubs died due to starvation in months when large prey was not available, or following take-over of the prides by new males. Male lions in coalitions are closely related.
+Between 1974 and 2012, 471 coalitions comprising 796 male lions entered a study area of 2,000 km2 (770 sq mi). Of these, 35 coalitions included male lions that were born in the area but had left and returned after about two years of absence. Nomadic coalitions became resident at between 3.5 and 7.3 years of age.The lion population of Selous Game Reserve has been surveyed since 1996. Lion prides avoided acacia woodlands and preferred habitats near water courses with short grasses, where also prey species gathered. Two or more prides shared home ranges.In Kavango–Zambezi Transfrontier Conservation Area, lions have been monitored since 1999. In 2003, 50 lions were radio-collared in Hwange National Park and tracked until 2012. Results show that adult male and female lions preferred grassland and shrubland habitat, but avoided woodlands and areas with high human density. By contrast, subadult dispersing male lions avoided grasslands and shrublands, but moved in human-dominated areas to a larger extent. Hence, dispersing lions are more vulnerable to coming into conflict with humans than adult lions.
+In the semi-arid savanna of Zimbabwe's Hwange National Park, 19 lions were radio-collared and tracked between 2002 and 2007. Both female and male lions moved foremost within 2 km (1.2 mi) of waterholes in all seasons.Lions living near ranches in the vicinity of Tsavo East National Park consisted of three prides, two pairs and a single lion in 2002.
+
+
+=== Hunting and diet ===
+
+Lions usually hunt in groups and prey foremost on ungulates such as gemsbok (Oryx gazella), Cape buffalo (Syncerus caffer), blue wildebeest (Connochaetes taurinus), giraffe (Giraffa camelopardalis), common eland (Tragelaphus oryx), greater kudu (T. strepsiceros), nyala (T. angasii), roan antelope (Hippotragus equinus), sable antelope (H. niger), plains zebra (Equus quagga), bushpig (Potamochoerus larvatus), common warthog (Phacochoerus africanus), hartebeest (Alcephalus buselaphus), common tsessebe (Damaliscus lunatus), waterbuck (Kobus ellipsiprymnus), kob (K. kob) and Thomson's gazelle (Eudorcas thomsonii). Their prey is usually in the range of 190–550 kg (420–1,210 pounds). In the Serengeti National Park, lions were observed to also scavenge on carrion of animals that were killed by other predators, or died from natural causes. They kept a constant lookout for circling vultures, apparently being aware that vultures indicate a dead animal.
+Faeces of lions collected near waterholes in Hwange National Park also contained remains of climbing mice (Dendromus) and common mice (Mus).In Botswana's Chobe National Park, lions also prey on young and subadult African bush elephants (Loxodonta africana). They successfully attacked 74 elephants between 1993 and 1996, of which 26 were older than nine years, and one bull over 15 years old. In October 2005, a pride of up to 30 lions killed eight African bush elephants that were between four and eleven years old.
+
+
+=== Attacks on humans ===
+Several cases of lion attacking people have been documented:
+
+In the 1890s, two Tsavo Man-Eaters attacked workers during the building of the Uganda Railway. Their skulls and skins are part of the zoological collection of the Field Museum of Natural History. The total number of people killed is unclear, but allegedly 135 people fell victim to these lions in less than a year before Colonel Patterson killed them.
+The Njombe lions were a lion pride in Njombe in former Tanganyika, which are thought to have preyed on 1,500 to 2,000 people. They were killed by George Gilman Rushby.
+Between 1990 and 2004, lions killed more than 560 people in Tanzania, mostly during harvest season in crop fields and in areas where natural prey is scarce.
+In February 2018, lions killed a suspected poacher near Kruger National Park.
+In February 2018, Kevin Richardson took three lions for a walk at Dinokeng Game Reserve in South Africa. A lioness pursued an impala for at least 2 km (1.2 mi), and  killed a young woman near her car.
+In July 2018, human remains were found in the lion enclosure of a privately owned reserve in South Africa. They were suspected to have been rhino poachers, as they had a high-powered rifle with a silencer, an axe and wire cutters.
+
+
+== Threats ==
+
+In Africa, lions are threatened by pre-emptive killing or in retaliation for preying on livestock. Prey base depletion, loss and conversion of habitat have led to a number of subpopulations becoming small and isolated. Trophy hunting has contributed to population declines in Botswana, Namibia, Zimbabwe and Zambia. It is the primary cause for a decline of lion populations in Tanzania's Selous Game Reserve and Katavi National Park. Although lions and their prey are officially protected in Tsavo National Parks, they are regularly killed by local people, with over 100 known lion killings between 2001 and 2006.Between 2008 and 2013, bones and body parts from at least 2621 individual lions were exported from South Africa to Southeast Asia, and another 3437 lion skeletons between 2014 and 2016. Lion bones are used to replace tiger bones in traditional Asian medicines. Private game ranches in South Africa also breed lions for the canned hunting industry.In 2014, seven lions in Ikona Wildlife Management Area were reportedly poisoned by a herdsman for attacking his cattle. In February 2018, the carcasses of two male and four female lions were found dead in Ruaha National Park, and were suspected to have died of poisoning.In 2015 and 2017, two male lions, Cecil and his son Xanda, were killed by trophy hunters in Zimbabwe's Hwange National Park.Uncontrolled bushfires and hunting of lions and prey species in Zambia's Kafue National Park make it difficult for the lion population to recover. Cub mortality in particular is high.
+
+
+== Conservation ==
+
+African lions are included in CITES Appendix II. Today, lion populations are stable only in large protected area complexes. IUCN regional offices and many wildlife conservation organisations cooperated to develop a Lion Conservation Strategy for Eastern and Southern Africa in 2006. The strategy envisages to maintain sufficient habitat, ensure a sufficient wild prey base, make lion-human coexistence sustainable and reduce factors that lead to further fragmentation of populations.
+Local communities in several Southern African lion range countries generate significant income through wildlife tourism, which is a strong incentive for their support of conservation measures.Establishing corridors between protected areas is important for facilitating dispersal of lions. Makgadikgadi Pans National Park and Central Kalahari Game Reserve are key dispersal areas in Southern Africa.
+
+
+=== In captivity ===
+
+At the beginning of the 21st century, the Addis Ababa Zoo kept 16 adult lions. It is assumed that their ancestors, five males and two females, were caught in southwestern Ethiopia as part of a zoological collection for Emperor Haile Selassie I.In 2006, eight captive lions were registered under the name P. l. massaicus, and 23 as P. l. nubicus from Tanzania by the International Species Information System; about 100 captive lions were registered  as P. l. krugeri, which derived from lions captured in South Africa.In 2012, samples of lions kept at Sana'a Zoo in Yemen were found to cluster with those of lions from East and Southern Africa.
+
+
+== Cultural significance ==
+
+The lion is an animal symbol in shamanistic rituals of the Nuer people. In other East African cultures, it symbolizes laziness. Scars inflicted by lions are regarded as a sign of courage among the Masai people.
+The name 'Simba' is a Swahili word for the lion, which also means 'aggressive', 'king' and 'strong'.
+
+
+== Regional names ==
+Lion populations in Southern and East Africa were referred to by several regional names, including Katanga lion, Transvaal lion, Kalahari lion, Southeast African lion, and Southwest African lion, Masai lion, Serengeti lion, Tsavo lion and Uganda lion. It has also been referred to as 'Eastern-Southern African lion', 'Southern lion', and as 'southern subspecies'.

+Panthera pardus tulliana is a leopard subspecies native to the Iranian Plateau and surrounding areas encompassing Turkey, the Caucasus, Azerbaijan, Georgia, Armenia, Iraq, Iran, Turkmenistan, Afghanistan and possibly Pakistan. Since 2016, it has been listed as Endangered on the IUCN Red List, as the wild population is estimated at less than 1000 mature individuals.Common names used for P. p. tulliana include Persian leopard, Caucasian leopard and Anatolian leopard.
+
+
+== Taxonomy ==
+
+Felis tulliana was the scientific name proposed by Achille Valenciennes in 1856, who described a skin and skull from a leopard killed near Smyrna, in western Turkey.
+In the 19th and 20th centuries, several naturalists described leopard zoological specimens from the Middle East:
+
+Felis pardus tulliana was proposed by Richard Lydekker in 1899 after examining a leopard skin from the Caucasus.
+Felis ciscaucasica was proposed by Konstantin Alekseevich Satunin in 1914, based on a leopard specimen from the Kuban region in the North Caucasus.
+Panthera pardus saxicolor was proposed by Reginald Innes Pocock in 1927, who described leopard skins from different areas of Persia, but recognized their similarity to Caucasian leopard skins. His holotype was a skin and a skull of a male leopard from Asterabad.
+P. p. sindica was proposed by Pocock in 1930 for a single skin and two skulls from the Kirthar Mountains in Balochistan. He wrote that the skin closely resembled those of P. p. saxicolor, but was distinguishable from the typical Indian leopard (P. p. fusca) in colour. It was subsumed to P. p. saxicolor based on molecular genetic analysis in 1996.In the 19th and 20th centuries, the Anatolian leopard was considered a distinct leopard subspecies that occurred only in western Turkey. The leopard specimens available in zoological museum collections do not differ significantly in the sizes and shapes of skulls. Therefore, the subspecific names tulliana, ciscaucasica and saxicolor are currently considered synonyms.An analysis of leopard samples from Afghanistan revealed that they belong to P. p. saxicolor, but intergrade with the Indian leopard (P. p. fusca) in eastern Afghanistan.In 2017, the Persian leopard population was subsumed to P. p. tulliana, which is the oldest available name for the leopard subspecies in West Asia.
+
+
+=== Phylogeny ===
+A phylogenetic analysis indicates that P. p. tulliana matrilineally belongs to a monophyletic group that diverged from the African (P. p. pardus) and the Arabian leopard (P. p. nimr) in the second half of the Pleistocene. DNA analysis indicates that the leopards in Iran belong to a single gene pool and form a distinct subclade.
+
+
+== Characteristics ==
+
+P. p. tulliana has a grayish, slightly reddish fur with large rosettes on the flanks and back, smaller ones on the shoulder and upper legs, and spots on the head and neck. It varies in colouration; in Iran both pale and dark individuals occur. Its average body length is 158 cm (62 in), with a 192 mm (7.6 in) long skull and a 94 cm (37 in) long tail. It weighs up to 60 kg (130 lb).Biometric data collected from 25 female and male individuals in various provinces of Iran indicate an average body length of 259 cm (102 in). A young male from northern Iran weighed 64 kg (141 lb).
+
+
+== Distribution and habitat ==
+The habitat of P. p. tulliana in the Greater Caucasus is subalpine meadows, temperate broadleaf and mixed forests and rugged ravines from 600 to 3,800 m (2,000 to 12,500 ft) ; and in the Lesser Caucasus and Iran rocky slopes, mountain steppes and sparse juniper forests. It avoids areas with long-duration snow cover and areas near urban development.In northern Anatolia, zoologists found evidence of leopards in the upper forest and alpine zones of the Pontic Mountains during surveys carried out between 1993 and 2002. Its presence in the Pontic Mountains was questioned in 2016 due to a lack of evidence. A camera trap photograph obtained in Trabzon Province in the Black Sea region in September 2013 is said to show a leopard. Its preferred habitat is thought to be sparse forest areas, followed by rocky areas, agriculture and pasture areas, and riparian zones.
+In southeastern Turkey, its presence was documented in the Çınar district of Diyarbakır Province and in Bitlis Province. In 2018 and 2019, it was photographed on the northern slopes of Mount Cudi in Şırnak Province, and this may be a corridor for movement between Turkey and Iraq. It has also been photographed in the north-eastern province of Artvin, which borders Georgia, but whether the animals are resident is not known.
+
+In the Caucasus, leopards were sighted around the Tbilisi area and in the Shida Kartli province in Georgia, where they live primarily in dense forests. Several individuals were sighted in the lowland plains of the Kakheti region in 2004.
+Leopard signs were also found at two localities in Tusheti, the headwaters of the Andi Koysu and Assa rivers bordering Dagestan. Leopards are thought to occasionally move through Georgia from Russia, but naturalists hope they might become resident in Georgia in future if well protected in both countries.
+Between October 2000 and July 2002, tracks of 10 leopards were found in an area of 780 km2 (300 sq mi) in the rugged and cliffy terrain of Khosrov State Reserve on the southwestern slopes of the Gegham mountains.
+During surveys in 2013–2014, camera traps recorded leopards in 24 locations in southern Armenia, of which 14 are in the Zangezur Mountains. This trans-boundary mountain range provides important breeding habitat for leopards in the Lesser Caucasus.
+In March 2007 and in October 2012, an individual was photographed by a camera trap in Hirkan National Park. This protected area in southeastern Azerbaijan is in the Talysh Mountains, which are contiguous with the Alborz Mountains in Iran. During surveys in 2013–2014, camera traps recorded leopards in five locations in Hirkan National Park.
+The first male leopard crossing from Hirkan National Park into Iran was documented in February 2014. It was killed in the Chubar Highlands in north-western Iran's Gilan Province by a local hunter. This incident indicates that the Talysh Mountains are an important corridor for trans-boundary movement of leopards.
+In September 2012, the first female leopard was photographed in Zangezur National Park close to the border with Iran.
+During surveys in 2013–2014, camera traps recorded leopards in seven locations in Zangezur National Park, including two different females and one male. All sites are close to the border with Iran.
+Five cubs were documented in two sites in the Lesser Caucasus and the Talysh Mountains. Between July 2014 and June 2018, four leopards were identified in the Talysh Mountains and 11 in the trans-boundary region of Nakhchivan and southern Armenia.Leopards have been sporadically recorded in northern Iraq.
+In October 2011 and January 2012, a leopard was photographed by a camera trap on Jazhna Mountain in the Zagros Mountains forest steppe in the Kurdistan Region.
+Between 2001 and 2014, at least nine leopards were killed by local people in this region. In 2020, a leopard was recorded in the mountains of the Sulaymaniyah Governorate in the country's northeast.
+
+Iran is considered a stronghold of the leopard in the region. It is more abundant in the northern than in the southern part of the country, and in the 2010s was recorded in 74 of 204 protected areas. The Caspian Hyrcanian mixed forests along the Alborz Mountains are one of the most important habitats for the leopard in the country. Most leopards were recorded in habitats with temperatures of 13 to 18 °C (55 to 64 °F), maximum 20 days of ice cover per year and an annual rainfall of more than 200 mm (7.9 in). The Central Alborz Protected Area covering more than 3,500 km2 (1,400 sq mi) is one of the largest reserves in the country where leopards roam. Evidence for breeding of leopards was documented in six localities inside protected areas in the Iranian part of the Lesser Caucasus.
+In northeastern Iran, four leopard families with two cubs each were identified during a survey carried out from 2005 to 2008 in Sarigol National Park. A male leopard was photographed in January 2008 spraying urine on a Berberis tree; he was photographed several times until mid-February 2008 in the same area. Camera trapping surveys in summer 2016 documented the presence of 52 leopards in Sarigol, Salouk and Tandooreh National Parks. These included 10 cubs in seven families, thus highlighting that the Kopet Dag and Aladagh Mountains are important leopard refugia in the region. Leopards were also photographed in a protected area in Sefid Kuh, Kermanshah in 2020.
+Between September 2014 and August 2016, two radio-collared leopards moved from Iran's Kopet Dag region into Turkmenistan, revealing that the leopard population in the two countries is connected. Leopards were recorded by camera traps in the Badkhyz Nature Reserve in the country's south-west.
+In 2017, a young male leopard from Iran's Tandooreh National Park dispersed to and settled in Turkmenistan.
+
+In 2018, an old male Persian leopard had moved 20 km (12 mi) from Iran to Turkmenistan.
+In Bamu National Park in Fars Province, surveys carried out from autumn 2007 to spring 2008 revealed seven individuals in a sampling area of 321.12 km2 (123.99 sq mi). One individual was recorded by a camera trap in Afghanistan's Bamyan Province in 2011.In Kazakhstan, a leopard was recorded for the first time in 2000 in Jambyl Region. In 2007 and 2015, two leopards were killed in Mangystau Region farther west in the country. Between September and December 2018, camera traps recorded a leopard on a cliff in Ustyurt Nature Reserve.
+
+
+=== Historical range ===
+P. p. tulliana was most likely distributed over the entire Caucasus, except for steppe areas. The northern foothills of the Greater Caucasus formed the northern boundary of its historic range. During surveys conducted between 2001 and 2005, no leopard was recorded in the western Greater Caucasus; it probably survived only at a few sites in the eastern part.
+In Armenia, people and leopards have co-existed since prehistoric times. In the mid-20th century, the leopard was relatively common in the country's mountains.
+
+Stone traps for leopards and other predators dating to the Roman Empire still exist in the Taurus Mountains in southern Turkey.
+The last leopard in Syria is reported to have been killed in 1963 in the Syrian Coastal Mountain Range.P. p. tulliana was once numerous in the Aegean Region between İzmir and Antalya, with the Beşparmak Mountains considered a stronghold. Several factors contributed to the decline of the leopard population in this region between the late 1940s and mid 1970s, including deforestation, conversion of natural habitat to orchards, road construction and killing of leopards in retaliation for preying on livestock. Since surveys were not carried out in western Turkey until the mid-1980s, biologists doubted whether leopards still survived in the region. Sighting reports from the environs of Alanya in the south of the Lycian peninsula suggested that a scattered population existed between Finike, Antalya and Alanya in the early 1990s. Fresh faecal pellets found in Mount Güllük-Termessos National Park in 1992 were attributed to an Anatolian leopard.
+However surveys in western Turkey between 2000 and 2004 found no contemporary evidence of leopards. Extensive trophy hunting is thought to be the prime factor for the decline of the Anatolian leopard in this area. One hunter named Mantolu Hasan killed at least fifteen leopards between 1930 and 1950. It is considered locally extinct in western Turkey since the mid-1970s. No signs of the presence of leopards were detected in Termessos National Park during surveys in 2005, and local people and national park personnel were not aware of any.The leopard population in southern Russia had been reduced to two small and isolated populations by the 1950s, and by 2007, there were fewer than 50 individuals in the region.
+Since 1954, leopards were thought to be extirpated in Georgia, following kills by hunters. The political and social changes caused by the breakup of the Soviet Union in 1992 caused a severe economic crisis and weakening of formerly effective protection systems; wildlife habitats were severely fragmented, leopards were persecuted and wild ungulates were hunted. In addition, inadequate baseline data and lack of monitoring programmes made it difficult to evaluate declines of mammalian prey species.
+In the winter of 2003, zoologists found footprints of a leopard in Vashlovani National Park in southeastern Georgia. Camera traps recorded one young male individual several times. The individual was not recorded again between 2009 and 2014. A survey in 2019 found no leopards.Leopards also survived in northwestern Azerbaijan in the Akhar-Bakhar section of Ilisu State Reserve in the foothills of the Greater Caucasus, but in 2007 numbers were thought to be extremely low.In Afghanistan, the leopard is thought to inhabit the central highlands of the Hindu Kush and the Wakhan corridor, but none have been photographed. The long-lasting conflict in the country badly affected both predator and prey species, so that the national population is considered to be small and severely threatened.
+
+
+== Behaviour and ecology ==
+The diet of P. p. tulliana varies depending on habitat.
+In southern Armenia and Iran, it preys mostly on wild goat (Capra aegagrus), mouflon (Ovis gmelini), wild boar (Sus scrofa), roe deer (Capreolus capreolus), goitered gazelle (Gazella subgutturosa), Indian crested porcupine (Hystrix indica) and European hare (Lepus europaeus). It occasionally attacks livestock and herding dogs. In Iran, the presence of leopards is highly correlated with the presence of wild goat and wild sheep. An attack by a leopard on an onager (Equus hemionus) was also recorded. In Turkey, it also preys on chamois (Rupicapra rupicapra).Adult males usually share their home ranges entirely or partially with two or three adult females. The mating season lasts from mid-January to mid-February. In Sarigol National Park, three females were documented in late April to May 2008 with one to two cubs each. A female with two cubs was also photographed in the Alborz Mountains.
+
+
+== Threats ==
+
+P. p. tulliana is threatened by poaching, depletion of prey base due to poaching, human disturbance such as presence of military and training of troops in border areas, habitat loss due to deforestation, fire, agricultural expansion, overgrazing, and infrastructure development.
+In the 1980s, anti-personnel mines were deployed along the northern part of the Iran-Iraq border to deter people from entering the area. Leopards roaming the area are safe from poachers and industrial development, but at least two individuals are known to have stepped on mines and been killed. The main threat in northern Iraq is deforestation, which in the early 2020s is being worsened by an economic crisis.In April 2001, an adult female was shot on the border to Kabardino-Balkaria; her two cubs were captured and taken to Novosibirsk Zoo in Russia.
+Between 2004 and 2007, a total of 85 leopard skins were seen being offered in markets in Kabul.
+Leopards were known to live on the Meghri Ridge in the extreme south of Armenia, where only one individual was imaged by a camera trap between August 2006 and April 2007, but no signs of other leopards were found during track surveys conducted over an area of 296.9 km2 (114.6 sq mi). The local prey base could support 4–10 individuals. But the combined impact of poaching, disturbance caused by livestock breeding, gathering of edible plants and mushrooms, deforestation and human-induced wild fires was so high that the tolerance limits of leopards was exceeded.
+Only some small and isolated populations remain in the whole Caucasus. Suitable habitat is limited, and most often situated in remote border areas. Local populations depend on immigration from source populations mainly in Iran.In Turkey, the leopard has been killed illegally in traps and through poison. Several leopards are known of have been killed since 1974 in Beypazarı, Siirt Province, Diyarbakır Province and Tunceli Provinces. Despite ongoing efforts to reforest Turkey, the country lacks a plan to reconnect fragmented forests as of 2020, which may further fragment leopard populations in the region.In Iran, primary threats are habitat disturbances, poaching and excess of livestock in leopard habitats. Leopards are unlikely to persist outside of protected areas. Droughts in wide areas of leopard habitats affected the main prey species such as wild goat and wild sheep.
+An assessment of leopard mortality in Iran revealed that 71 leopards were killed between 2007 and 2011 in 18 provinces; 70% were hunted or poisoned illegally, and 18% died in road accidents. Between 2000 and 2015, 147 leopards were killed in the country. More than 60% of them died due to poaching, through poisonous bait, and were shot by rangers, trophy hunters and the military. About 26% of them died in road accidents. More males than females were killed.
+Between 2007 and spring 2021, 78 leopards died in Iran because of humans; 62 were shot or poisoned by herders or killed by their dogs.
+Retaliatory killings of leopards occur after attacks on livestock.
+Leopards injured 30 people and killed one in the country between 2012 and 2020, mostly thought to be defensive reactions by animals surprised by livestock herders.
+
+
+== Conservation ==
+Panthera pardus is listed in CITES Appendix I. It is listed as a strictly protected species in Appendix II of the Berne Convention on the Conservation of European Wildlife and Natural Habitats.
+In Azerbaijan, the leopard has been protected by law since 1969; in Armenia and in the Soviet Union, it was protected by law in 1972; the Caucasus leopard population was listed in Russia's Red Data Book under Category I as threatened with extinction.
+It has been protected by law in Iran since 1999.
+In 2001, hunting leopards was banned in Nakhchivan Autonomous Republic, and anti-poaching activities were regularly conducted in southern Armenia since 2003. Since 2005, seven protected areas have been established in the Lesser Caucasus covering an area of 1,940 km2 (750 sq mi), and three in the Talysh Mountains with an area of 449 km2 (173 sq mi). The total protected area in the country now amounts to 4,245 km2 (1,639 sq mi).
+In Georgia's national Red Data Book, the leopard has been listed as Critically Endangered since 2006. Penalties for killing leopards were adopted and increased several times in Armenia and Azerbaijan.
+In Afghanistan, it was included in the country's Protected Species List in 2009.
+In Kazakhstan, hunting was made a criminal offence in 2021. In Turkey the leopard is one of the species in the action plan being prepared for the country's endangered species.In 2001, a 5-year leopard conservation project was initiated in the Caucasus, which supported systematic surveys in the region, the planning of new and enlargement of existing protected areas, training of border guards and school education campaigns in Armenia and Azerbaijan; an anti-poaching unit was set up in Armenia. In 2005, the Armenian Ministry of Environment approved a conservation plan with the leopard as an umbrella species, and a strategy for leopard conservation in the Caucasus in 2008.
+In Iran, a leopard conservation and management action plan was endorsed in 2016, and Future4Leopards Foundation is a non-profit conservation organization in the country. As of 2019, Nature Iraq is mapping potential habitat near the border with Iran as the first stage of a conservation project.Wildlife corridors for the safe dispersal of leopards between there and other protected areas in Iran's Alborz Mountains have been mapped in an area of 3,132 km2 (1,209 sq mi). As of 2022 further conservation work is needed to conserve corridors, including protecting more areas. Three core habitats and suitable corridors between protected areas in the Zagros Mountains were identified along the international border between Iran and Iraq.In 2021, several authors suggested that there is enough suitable habitat in the Caucasus as a whole for over a thousand leopards, but a metapopulation will only be viable if persecution is reduced and prey restored.
+
+
+=== Reintroduction projects ===
+In 2009, the Leopard Breeding and Rehabilitation Centre in Russia's Sochi National Park received two leopards from Turkmenistan as part of a leopard breeding and reintroduction programme. Since then, leopards have been brought from various zoos. Their offspring were released into the wild in 2016 and 2018, including three males and one female into the Caucasus Biosphere Reserve, and one male and one female into Alaniya National Park in North Ossetia–Alania.
+
+
+=== In captivity ===
+As of 2021 there are over 100 captive Persian leopards in zoos worldwide, and the European Endangered Species Programme has a captive breeding program to sustain a backup population.
+
+
+== In culture ==
+In 2015, representations of the Anatolian leopard were found in the ancient city of Thyatira in Anatolia that date from the Neolithic period to the end of the 6th century BC. The leopard is depicted on statues, potteries, ivory works and coins associated with the Lydian culture. Several pieces were found in areas that were used for worship. Leopard skin patterns were also used on Anatolian carpets and kaftans.The Natural History Museum of the Aegean on Samos Island in Greece exhibits a stuffed animal said to have been killed on the island in 1862, labelled Kaplani, Greek: Καπλάνι, meaning leopard. Its size, shape and coat colour is rather unnatural for a leopard, but may have been altered in the process of taxidermy. It is possible that a leopard reached the island by swimming across the 1.7 km (1.1 mi) wide channel from the Turkish coast. One more leopard had reached Samos in 1836 and was trapped.The story of the leopard and the exhibit inspired Greek author Alki Zei to write a novel for children titled Greek: Το καπλάνι της βιτρίνας, translated as Wildcat Under Glass.

+The leopard (Panthera pardus) is one of the five extant species in the genus Panthera, a member of the cat family, Felidae. It occurs in a wide range in sub-Saharan Africa, in some parts of Western and Central Asia, Southern Russia, and on the Indian subcontinent to Southeast and East Asia. It is listed as Vulnerable on the IUCN Red List because leopard populations are threatened by habitat loss and fragmentation, and are declining in large parts of the global range. The leopard is considered locally extinct in Hong Kong, Singapore, South Korea, Jordan, Morocco, Togo, the United Arab Emirates, Uzbekistan, Lebanon, Mauritania, Kuwait, Syria, Libya, Tunisia and most likely in North Korea, Gambia, Laos, Lesotho, Tajikistan, Vietnam and Israel.
+Contemporary records suggest that the leopard occurs in only 25% of its historical global range.Compared to other wild cats, the leopard has relatively short legs and a long body with a large skull. Its fur is marked with rosettes. It is similar in appearance to the jaguar (Panthera onca), but has a smaller, lighter physique, and its rosettes are generally smaller, more densely packed and without central spots. Both leopards and jaguars that are melanistic are known as black panthers. The leopard is distinguished by its well-camouflaged fur, opportunistic hunting behaviour, broad diet, strength, and its ability to adapt to a variety of habitats ranging from rainforest to steppe, including arid and montane areas. It can run at speeds of up to 58 km/h (36 mph). The earliest known leopard fossils excavated in Europe are estimated 600,000 years old, dating to the late Early Pleistocene. Leopard fossils were also found in Sumatra, Taiwan and Japan.
+
+
+== Etymology ==
+The English name 'leopard' comes from Old French: leupart or Middle French: liepart, that derives from Latin: leopardus and Ancient Greek: λέοπάρδος (leopardos). Leopardos could be a compound of λέων (leōn), meaning lion, and πάρδος (pardos), meaning spotted. The word λέοπάρδος originally referred to a cheetah (Acinonyx jubatus).'Panther' is another common name, derived from Latin: panther and Ancient Greek: πάνθηρ (pánthēr); The generic name Panthera originates in Latin: panthera, which refers to a hunting net for catching wild beasts that were used by the Romans in combats. Pardus is the masculine singular form.
+
+
+== Characteristics ==
+
+The leopard's fur is generally soft and thick, notably softer on the belly than on the back. Its skin colour varies between individuals from pale yellowish to dark golden with dark spots grouped in rosettes. Its belly is whitish and its ringed tail is shorter than its body. Its pupils are round. Leopards living in arid regions are pale cream, yellowish to ochraceous and rufous in colour; those living in forests and mountains are much darker and deep golden. Spots fade toward the white underbelly and the insides and lower parts of the legs. Rosettes are circular in East African leopard populations, and tend to be squarish in Southern African and larger in Asian leopard populations. The fur tends to be grayish in colder climates, and dark golden in rain forest habitats. The pattern of the rosettes is unique in each individual. This pattern is thought to be an adaptation to dense vegetation with patchy shadows, where it serves as camouflage.Its white-tipped tail is about 60–100 cm (23.6–39.4 in) long, white underneath and with spots that form incomplete bands toward the tail's end.
+The guard hairs protecting the basal hairs are short, 3–4 mm (0.1–0.2 in) in face and head, and increase in length toward the flanks and the belly to about 25–30 mm (1.0–1.2 in). Juveniles have woolly fur, and appear to be dark-coloured due to the densely arranged spots. 
+Its fur tends to grow longer in colder climates.
+The leopard's rosettes differ from those of the jaguar (Panthera onca), which are darker and with smaller spots inside.The leopard has a diploid chromosome number of 38.
+The chromosomes include four acrocentric, five metacentric, seven submetacentric and two telocentric pairs.
+
+
+=== Size and weight ===
+The leopard is sexually dimorphic with males larger and heavier than females. It is slender and muscular, with relatively short limbs and a broad head. Males stand 60–70 cm (23.6–27.6 in) at the shoulder, while females are 57–64 cm (22.4–25.2 in) tall. The head-and-body length ranges between 90 and 196 cm (2 ft 11.4 in and 6 ft 5.2 in) with a 66 to 102 cm (2 ft 2.0 in to 3 ft 4.2 in) long tail. Sizes vary geographically. Males weigh 37–90 kg (81.6–198.4 lb), and females 28–60 kg (61.7–132.3 lb).
+Some leopards in North Africa allegedly were as large as Barbary lions (Panthera leo leo). In 1913, an Algerian newspaper reported a leopard killed that allegedly measured about 275 cm (9 ft 0 in) in total length.
+The maximum weight of a wild leopard in Southern Africa was about 96 kg (212 lb). It measured 262 cm (8 ft 7.1 in). An Indian leopard killed in Himachal Pradesh in 2016 measured 261 cm (8 ft 6.8 in) with an estimated weight of 78.5 kg (173.1 lb); it was perhaps the largest known wild leopard in India.The largest skull of a leopard was recorded in India in 1920 and measured 28 cm (11.0 in) in basal length, 20 cm (7.9 in) in breadth, and weighed 1,000 g (2 lb 4 oz). The skull of an African leopard measured 285.8 mm (11.25 in) in basal length, and 181.0 mm (7.125 in) in breadth, and weighed 790 g (1 lb 12 oz).
+
+
+=== Variant colouration ===
+
+Melanistic leopards are also called black panthers. Melanism in leopards is caused by a recessive allele and inherited as a recessive trait. Interbreeding in melanistic leopards produces a significantly smaller litter size than is produced by normal pairings.
+The black leopard is common foremost in tropical and subtropical moist forests like the equatorial rainforest of the Malay Peninsula and the tropical rainforest on the slopes of some African mountains such as Mount Kenya.
+Between January 1996 and March 2009, leopards were photographed at 16 sites in the Malay Peninsula in a sampling effort of more than 1,000 camera trap nights. Of the 445 photographs of melanistic leopards, 410 were taken in study sites south of the Kra Isthmus, where the non-melanistic morph was never photographed. These data indicate the near-fixation of the dark allele in the region. The expected time for the fixation of this recessive allele due to genetic drift alone ranged from about 1,100 years to about 100,000 years. Pseudomelanistic leopards have also been reported.In India, nine pale and white leopards were reported between 1905 and 1967.
+Leopards exhibiting erythrism were recorded between 1990 and 2015 in South Africa's Madikwe Game Reserve and in Mpumalanga. The cause of this morph known as a "strawberry leopard" or "pink panther" is not well understood.
+
+
+== Taxonomy ==
+
+Felis pardus was the scientific name proposed by Carl Linnaeus in 1758.
+The generic name Panthera was first used by Lorenz Oken in 1816, who included all the known spotted cats into this group.
+Oken's classification was not widely accepted, and Felis or Leopardus was used as the generic name until the early 20th century.The leopard was designated as the type species of Panthera by Joel Asaph Allen in 1902.
+In 1917, Reginald Innes Pocock also subordinated the tiger (P. tigris), lion (P. leo), and jaguar (P. onca) to Panthera.
+
+
+=== Subspecies ===
+Following Linnaeus' first description, 27 leopard subspecies were proposed by naturalists between 1794 and 1956. Since 1996, only eight subspecies have been considered valid on the basis of mitochondrial analysis. Later analysis revealed a ninth valid subspecies, the Arabian leopard.In 2017, the Cat Classification Task Force of the Cat Specialist Group recognized the following eight subspecies as valid taxa:
+Results of an analysis of molecular variance and pairwise fixation index of 182 African leopard museum specimens showed that some African leopards exhibit higher genetic differences than Asian leopard subspecies.
+
+
+=== Evolution ===
+
+Results of phylogenetic studies based on nDNA and mtDNA analysis showed that the last common ancestor of the Panthera and Neofelis genera is thought to have lived about 6.37 million years ago. Neofelis diverged about 8.66 million years ago from the Panthera lineage. The tiger diverged about 6.55 million years ago, followed by the snow leopard about 4.63 million years ago and the leopard about 4.35 million years ago. The leopard is a sister taxon to a clade within Panthera, consisting of the lion and the jaguar.Results of a phylogenetic analysis of chemical secretions amongst cats indicated that the leopard is closely related to the lion.
+The geographic origin of the Panthera is most likely northern Central Asia. The leopard-lion clade was distributed in the Asian and African Palearctic since at least the early Pliocene. The leopard-lion clade diverged 3.1–1.95 million years ago. Additionally, a 2016 study revealed that the mitochondrial genomes of the leopard, lion and snow leopard are more similar to each other than their nuclear genomes, indicating that their ancestors hybridized with the snow leopard at some point in their evolution.Fossils of leopard ancestors were excavated in East Africa and South Asia, dating back to the Pleistocene between 2 and 3.5 million years ago. The modern leopard is suggested to have evolved in Africa about 0.5 to 0.8 million years ago and to have radiated across Asia about 0.2 and 0.3 million years ago.
+Fossil cat teeth collected in Sumatra's Padang Highlands were assigned to the leopard. It has since been hypothesized that it became extirpated on the island due to the Toba eruption about 75,000 years ago, and due to competition with the Sunda clouded leopard (Neofelis diardi) and the dhole (Cuon alpinus).In Europe, the leopard occurred at least since the Pleistocene. Leopard-like fossil bones and teeth possibly dating to the Pliocene were excavated in Perrier in France, northeast of London, and in Valdarno, Italy. Until 1940, similar fossils dating back to the Pleistocene were excavated mostly in loess and caves at 40 sites in Europe, including Furninha Cave near Lisbon, Genista Caves in Gibraltar, and Santander Province in northern Spain to several sites across France, Switzerland, Italy, Austria, Germany, in the north up to Derby in England, in the east to Přerov in the Czech Republic and the Baranya in southern Hungary, Leopard fossils dating to the Late Pleistocene were found in Biśnik Cave in south-central Poland. The oldest known leopard fossils excavated in Europe are about 600,000 years old and were found in the Grotte du Vallonnet in France and near Mauer in Germany. Four European Pleistocene leopard subspecies were proposed. P. p. begoueni from the beginning of the Early Pleistocene was replaced about 0.6 million years ago by P. p. sickenbergi, which in turn was replaced by P. p. antiqua around 0.3 million years ago. The most recent, P. p. spelaea, appeared at the beginning of the Late Pleistocene and survived until about 24,000 years ago in several parts of Europe. Leopard fossils dating to the Pleistocene were also excavated in the Japanese archipelago.
+
+
+=== Hybrids ===
+
+In 1953, a male leopard and a lioness were crossbred in Hanshin Park in Nishinomiya, Japan. Their offspring known as a leopon was born in 1959 and 1961, all cubs were spotted and bigger than a juvenile leopard. Attempts to mate a leopon with a tigress were unsuccessful.
+
+
+== Distribution and habitat ==
+
+The leopard has the largest distribution of all wild cats, occurring widely in Africa, the Caucasus and Asia, although populations are fragmented and declining. It is considered to be extirpated in North Africa. It inhabits foremost savanna and rainforest, and areas where grasslands, woodlands, and riverine forests remain largely undisturbed. In sub-Saharan Africa, it is still numerous and surviving in marginal habitats where other large cats have disappeared. There is considerable potential for human-leopard conflict due to leopards preying on livestock.Leopard populations on the Arabian Peninsula are small and fragmented. In southeastern Egypt, a leopard killed in 2017 was the first record in this area in 65 years.
+In western and central Asia, it avoids deserts, areas with long snow cover and proximity to urban centres.In the Indian subcontinent, the leopard is still relatively abundant, with greater numbers than those of other Panthera species. As of 2020, the leopard population within forested habitats in India's tiger range landscapes was estimated at 12,172 to 13,535 individuals. Surveyed landscapes included elevations below 2,600 m (8,500 ft)  in the Shivalik Hills and Gangetic plains, Central India and Eastern Ghats, Western Ghats, the Brahmaputra River basin and hills in Northeast India. Some leopard populations in the country live quite close to human settlements and even in semi-developed areas. Although adaptable to human disturbances, leopards require healthy prey populations and appropriate vegetative cover for hunting for prolonged survival and thus rarely linger in heavily developed areas. Due to the leopard's stealth, people often remain unaware that it lives in nearby areas.In Nepal's Kanchenjunga Conservation Area, a melanistic leopard was photographed at an elevation of 4,300 m (14,100 ft) by a camera trap in May 2012. In Sri Lanka, leopards were recorded in Yala National Park and in unprotected forest patches, tea estates, grasslands, home gardens, pine and eucalyptus plantations.
+In Myanmar, leopards were recorded for the first time by camera traps in the hill forests of Myanmar's Karen State. The Northern Tenasserim Forest Complex in southern Myanmar is considered a leopard stronghold. In Thailand, leopards are present in the Western Forest Complex, Kaeng Krachan-Kui Buri, Khlong Saeng-Khao Sok protected area complexes and in Hala Bala Wildlife Sanctuary bordering Malaysia. In Peninsular Malaysia, leopards are present in Belum-Temengor, Taman Negara and Endau-Rompin National Parks.
+In Laos, leopards were recorded in Nam Et-Phou Louey National Biodiversity Conservation Area and Nam Kan National Protected Area.
+In Cambodia, leopards inhabit deciduous dipterocarp forest in Phnom Prich Wildlife Sanctuary and Mondulkiri Protected Forest.
+In southern China, leopards were recorded only in the Qinling Mountains during surveys in 11 nature reserves between 2002 and 2009.In Java, leopards inhabit dense tropical rainforests and dry deciduous forests at elevations from sea level to 2,540 m (8,330 ft). Outside protected areas, leopards were recorded in mixed agricultural land, secondary forest and production forest between 2008 and 2014.In the Russian Far East, it inhabits temperate coniferous forests where winter temperatures reach a low of −25 °C (−13 °F).
+
+
+== Behaviour and ecology ==
+
+The leopard is a solitary and territorial animal. It is typically shy and alert when crossing roadways and encountering oncoming vehicles, but may be emboldened to attack people or other animals when threatened. Adults associate only in the mating season. Females continue to interact with their offspring even after weaning and have been observed sharing kills with their offspring when they can not obtain any prey. They produce a number of vocalizations, including growls, snarls, meows, and purrs. The roaring sequence in leopards consists mainly of grunts, also called "sawing", as it resembles the sound of sawing wood. Cubs call their mother with a urr-urr sound.The whitish spots on the back of its ears are thought to play a role in communication.
+It has been hypothesized that the white tips of their tails may function as a 'follow-me' signal in intraspecific communication. However, no significant association were found between a conspicuous colour of tail patches and behavioural variables in carnivores.
+
+Leopards are active mainly from dusk till dawn and rest for most of the day and for some hours at night in thickets, among rocks or over tree branches. Leopards have been observed walking 1–25 km (0.62–15.53 mi) across their range at night; they may even wander up to 75 km (47 mi) if disturbed. In some regions, they are nocturnal. In western African forests, they have been observed to be largely diurnal and hunting during twilight, when their prey animals are active; activity patterns vary between seasons.
+
+Leopards can climb trees very skillfully, often rest on tree branches and descend from trees headfirst.
+They can run at over 58 km/h (36 mph), leap over 6 m (20 ft) horizontally, and jump up to 3 m (9.8 ft) vertically.
+
+
+=== Social spacing ===
+In Kruger National Park, most leopards tend to keep 1 km (0.62 mi) apart. Males interact with their partners and cubs at times, and exceptionally this can extend beyond to two generations. Aggressive encounters are rare, typically limited to defending territories from intruders. In a South African reserve, a male was wounded in a male–male territorial battle over a carcass.Males occupy home ranges that often overlap with a few smaller female home ranges, probably as a strategy to enhance access to females. In the Ivory Coast, the home range of a female was completely enclosed within a male's. Females live with their cubs in home ranges that overlap extensively, probably due to the association between mothers and their offspring. There may be a few other fluctuating home ranges belonging to young individuals. It is not clear if male home ranges overlap as much as those of females do. Individuals try to drive away intruders of the same sex.A study of leopards in the Namibian farmlands showed that the size of home ranges was not significantly affected by sex, rainfall patterns or season; the higher the prey availability in an area, the greater the leopard population density and the smaller the size of home ranges, but they tend to expand if there is human interference.
+Sizes of home ranges vary geographically and depending on habitat and availability of prey. In the Serengeti, males have home ranges of 33–38 km2 (13–15 sq mi) and females of 14–16 km2 (5.4–6.2 sq mi); but males in northeastern Namibia of 451 km2 (174 sq mi) and females of 188 km2 (73 sq mi). They are even larger in arid and montane areas. In Nepal's Bardia National Park, male home ranges of 48 km2 (19 sq mi) and female ones of 5–7 km2 (1.9–2.7 sq mi) are smaller than those generally observed in Africa.
+
+
+=== Hunting and diet ===
+The leopard is a carnivore that prefers medium-sized prey with a body mass ranging from 10–40 kg (22–88 lb). Prey species in this weight range tend to occur in dense habitat and to form small herds. Species that prefer open areas and have well-developed anti-predator strategies are less preferred. More than 100 prey species have been recorded. The most preferred species are ungulates, such as impala (Aepyceros melampus), bushbuck (Tragelaphus scriptus), common duiker (Sylvicapra grimmia) and chital (Axis axis). Primates preyed upon include white-eyelid mangabeys (Cercocebus sp.), guenons (Cercopithecus sp.) and gray langurs (Semnopithecus sp.). Leopards also kill smaller carnivores like black-backed jackal (Lupulella mesomelas), bat-eared fox (Otocyon megalotis), genet (Genetta sp.) and cheetah.The largest prey killed by a leopard was reportedly a male eland weighing 900 kg (2,000 lb). A study in Wolong National Nature Reserve in southern China demonstrated variation in the leopard's diet over time; over the course of seven years, the vegetative cover receded, and leopards opportunistically shifted from primarily consuming tufted deer (Elaphodus cephalophus) to pursuing bamboo rats (Rhizomys sinense) and other smaller prey.The leopard depends mainly on its acute senses of hearing and vision for hunting. It primarily hunts at night in most areas. In western African forests and Tsavo National Park, they have also been observed hunting by day. They usually hunt on the ground. In the Serengeti, they have been observed to ambush prey by jumping down on it from trees.The animal stalks its prey and tries to approach as closely as possible, typically within 5 m (16 ft) of the target, and, finally, pounces on it and kills it by suffocation. It kills small prey with a bite to the back of the neck, but holds larger animals by the throat and strangles them. It caches kills up to 2 km (1.2 mi) apart. It is able to take large prey due to its powerful jaw muscles, and is therefore strong enough to drag carcasses heavier than itself up into trees; an individual was seen to haul a young giraffe weighing nearly 125 kg (276 lb) up 5.7 m (18 ft 8 in) into a tree. It eats small prey immediately, but drags larger carcasses over several hundred metres and caches it safely in trees, bushes or even caves; this behaviour allows the leopard to store its prey away from rivals, and offers it an advantage over them. The way it stores the kill depends on local topography and individual preferences, varying from trees in Kruger National Park to bushes in the plain terrain of the Kalahari.Average daily consumption rates of 3.5 kg (7 lb 11 oz) were estimated for males and of 2.8 kg (6 lb 3 oz) for females. In the southern Kalahari Desert, leopards meet their water requirements by the bodily fluids of prey and succulent plants; they drink water every two to three days and feed infrequently on moisture-rich plants such as gemsbok cucumbers (Acanthosicyos naudinianus), watermelon (Citrullus lanatus) and Kalahari sour grass (Schmidtia kalahariensis).
+
+
+=== Enemies and competitors ===
+ 
+In parts of its global range, the leopard is sympatric with other large predators such as the tiger (Panthera tigris), lion (P. leo), cheetah, spotted hyena (Crocuta crocuta), striped hyena (Hyaena hyaena), brown hyena (Parahyaena brunnea), African wild dog (Lycaon pictus), dhole (Cuon alpinus), wolf (Canis lupus) and up to five bear species. Some of these species steal its kills, kill its cubs and even kill adult leopards. Leopards retreat up a tree in the face of direct aggression, and were observed when killing or preying on smaller competitors such as black-backed jackal, African civet (Civettictis civetta), caracal (Caracal caracal) and African wildcat (Felis lybica). Leopards generally seem to avoid encounters with adult bears, but kill vulnerable bear cubs. In Sri Lanka, a few recorded vicious fights between leopards and sloth bears (Melursus ursinus) apparently result in both animals winding up either dead or grievously injured.While interspecies killing of full-grown leopards is generally rare, given the opportunity, both tiger and lion readily kill and consume both young and adult leopards. In the Kalahari Desert, leopards frequently lose kills to brown hyenas, if the leopard is unable to move the kill into a tree. Single brown hyenas have been observed charging at and displacing male leopards from kills. Lions occasionally fetch leopard kills from trees.Resource partitioning occurs where leopards share their range with tigers. Leopards tend to take smaller prey, usually less than 75 kg (165 lb), where tigers are present.
+In areas where leopard and tiger are sympatric, coexistence is reportedly not the general rule, with leopards being few where tigers are numerous. Tigers appear to inhabit the deep parts of a forest while leopards are pushed closer to the fringes. In tropical forests, leopards do not always avoid the larger cats by hunting at different times. With relatively abundant prey and differences in the size of prey selected, tigers and leopards seem to successfully coexist without competitive exclusion or interspecies dominance hierarchies that may be more common to the leopard's co-existence with the lion in savanna habitats.Nile crocodiles (Crocodylus niloticus) prey on leopards occasionally. One large adult leopard was grabbed and consumed by a large crocodile while attempting to hunt along a bank in Kruger National Park. Mugger crocodiles (Crocodylus palustris) reportedly killed an adult leopard in Rajasthan. An adult leopard was recovered from the stomach of a 5.5 m (18 ft 1 in) Burmese python (Python bivittatus). In Serengeti National Park, troops of 30–40 olive baboons (Papio anubis) were observed while mobbing and attacking a female leopard and her cubs.
+
+
+=== Reproduction and life cycle ===
+
+In some areas, leopards mate all year round. In Manchuria and Siberia, they mate during January and February. The female's estrous cycle lasts about 46 days, and she usually is in heat for 6–7 days. The generation length of the leopard is 9.3 years. Gestation lasts for 90 to 105 days. Cubs are usually born in a litter of 2–4 cubs. Mortality of cubs is estimated at 41–50% during the first year.Females give birth in a cave, crevice among boulders, hollow tree or thicket. Cubs are born with closed eyes, which open four to nine days after birth. The fur of the young tends to be longer and thicker than that of adults. Their pelage is also more gray in colour with less defined spots. Around three months of age, the young begin to follow the mother on hunts. At one year of age, cubs can probably fend for themselves, but remain with the mother for 18–24 months.The average typical life span of a leopard is 12–17 years. The oldest leopard was a captive female that died at the age of 24 years, 2 months and 13 days.
+
+
+== Conservation issues ==
+The leopard is listed on CITES Appendix I, and trade is restricted to skins and body parts of 2,560 individuals in 11 sub-Saharan countries. The leopard is primarily threatened by habitat fragmentation and conversion of forest to agriculturally used land, which lead to a declining natural prey base, human–wildlife conflict with livestock herders and high leopard mortality rates. It is also threatened by trophy hunting and poaching.Between 2002 and 2012, at least four leopards were estimated to have been poached per week in India for the illegal wildlife trade of its skins and bones.
+In spring 2013, 37 leopard skins were found during a 7-week long market survey in major Moroccan cities. In 2014, 43 leopard skins were detected during two surveys in Morocco. Vendors admitted to have imported skins from sub-Saharan Africa.Surveys in the Central African Republic's Chinko area revealed that the leopard population decreased from 97 individuals in 2012 to 50 individuals in 2017. In this period, transhumant pastoralists from the border area with Sudan moved in the area with their livestock. Rangers confiscated large amounts of poison in the camps of livestock herders who were accompanied by armed merchants. They engaged in poaching large herbivores, sale of bushmeat and trading leopard skins in Am Dafok.In Java, the leopard is threatened by illegal hunting and trade. Between 2011 and 2019, body parts of 51 Javan leopards were seized including six live individuals, 12 skins, 13 skulls, 20 canines and 22 claws.
+
+
+== Human interaction ==
+
+
+=== Cultural significance ===
+
+Leopards have featured in art, mythology and folklore of many countries. In Greek mythology, it was a symbol of the god Dionysus, who was depicted wearing leopard skin and using leopards as means of transportation. In one myth, the god was captured by pirates but two leopards rescued him. During the Benin Empire, the leopard was commonly represented on engravings and sculptures and was used to symbolise the power of the king or oba, since the leopard was considered the king of the forest. The Ashanti also used the leopard as a symbol of leadership, and only the king was permitted to have a ceremonial leopard stool. Some African cultures considered the leopard to be a smarter, better hunter than the lion and harder to kill.In Rudyard Kipling's "How the Leopard Got His Spots", one of his Just So Stories, a leopard with no spots in the High Veldt lives with his hunting partner, the Ethiopian. When they set off to the forest, the Ethiopian changed his brown skin, and the leopard painted spots on his skin. A leopard played an important role in the 1938 Hollywood film Bringing Up Baby. African chiefs, European queens, Hollywood actors and burlesque dancers wore coats made of leopard skins.The leopard is a frequently used in heraldry, most commonly as passant. The heraldic leopard lacks spots and sports a mane, making it visually almost identical to the heraldic lion, and the two are often used interchangeably. Naturalistic leopard-like depictions appear on the coat of arms of Benin, Malawi, Somalia, the Democratic Republic of the Congo and Gabon, the last of which uses a black panther.
+
+
+=== Attacks on people ===
+
+The Leopard of Rudraprayag killed more than 125 people; the Panar Leopard was thought to have killed more than 400 people. Both were shot by British hunter Jim Corbett. The spotted devil of Gummalapur killed about 42 people in Karnataka, India.
+
+
+=== In captivity ===
+The Ancient Romans kept leopards in captivity to be slaughtered in hunts as well as be used in executions of criminals. In Benin, leopards were kept and paraded as mascots, totems and sacrifices to deities. Several leopards were kept in a menagerie established by King John of England at the Tower of London in the 13th century; around 1235, three of these animals were given to Henry III by Holy Roman Emperor Frederick II. In modern times, leopards have been trained and tamed in circuses.

+The Siberian tiger or Amur tiger is a population of the tiger subspecies Panthera tigris tigris native to the Russian Far East, Northeast China and possibly North Korea. It once ranged throughout the Korean Peninsula, but currently inhabits mainly the Sikhote-Alin mountain region in southwest Primorye Province in the Russian Far East. In 2005, there were 331–393 adult and subadult Siberian tigers in this region, with a breeding adult population of about 250 individuals. The population had been stable for more than a decade because of intensive conservation efforts, but partial surveys conducted after 2005 indicate that the Russian tiger population was declining. An initial census held in 2015 indicated that the Siberian tiger population had increased to 480–540 individuals in the Russian Far East, including 100 cubs. This was followed up by a more detailed census which revealed there was a total population of 562 wild Siberian tigers in Russia. As of 2014, about 35 individuals were estimated to range in the international border area between Russia and China.The Siberian tiger is genetically close to the now-extinct Caspian tiger. Results of a phylogeographic study comparing mitochondrial DNA from Caspian tigers and living tiger populations indicate that the common ancestor of the Siberian and Caspian tigers colonized Central Asia from eastern China, via the Gansu−Silk Road corridor, and then subsequently traversed Siberia eastward to establish the Siberian tiger population in the Russian Far East. The Caspian and Siberian tiger populations were the northernmost in mainland Asia.The Siberian tiger was also called "Amur tiger", "Manchurian tiger", "Korean tiger", and "Ussurian tiger", depending on the region where individuals were observed.
+
+
+== Taxonomy ==
+
+Felis tigris was the scientific name proposed by Carl Linnaeus in 1758 for the tiger. In the 19th century, several tiger specimens were collected in East Asia and described:
+
+Felis tigris altaicus proposed by Coenraad Jacob Temminck in 1844 were tiger skins with long hairs and dense coats sold in Japan, which originated in Korea, most likely from animals killed in the Altai and Pisihan Mountains.
+Tigris longipilis proposed by Leopold Fitzinger in 1868 was based on a long-haired tiger skin in the Natural History Museum, Vienna.
+Felis tigris var. amurensis proposed by Charles Dode in 1871 was based on tiger skins from the Amur region.
+Felis tigris coreensis by Emil Brass in 1904 was a tiger skin from Korea.The validity of several tiger subspecies was questioned in 1999. Most putative subspecies described in the 19th and 20th centuries were distinguished on the basis of fur length and colouration, striping patterns and body size – characteristics that vary widely within populations. Morphologically, tigers from different regions vary little, and gene flow between populations in those regions is considered to have been possible during the Pleistocene. Therefore, it was proposed to recognize only two tiger subspecies as valid, namely Panthera tigris tigris in mainland Asia, and P. t. sondaica in the Greater Sunda Islands and possibly in Sundaland.
+In 2015, morphological, ecological and molecular traits of all putative tiger subspecies were analysed in a combined approach. Results support distinction of the two evolutionary groups: continental and Sunda tigers. The authors proposed recognition of only two subspecies: namely P. t. tigris comprising the Bengal, Malayan, Indochinese, South China, Siberian and Caspian tiger populations; and P. t. sondaica comprising the Javan, Bali and Sumatran tiger populations.In 2017, the Cat Specialist Group revised felid taxonomy and now recognizes all the tiger populations in mainland Asia as P. t. tigris.
+
+
+=== Phylogeny ===
+
+Several reports have been published since the 1990s on the genetic makeup of the Siberian tiger and its relationship to other populations. One of the most important outcomes has been the discovery of low genetic variability in the wild population, especially when it comes to maternal or mitochondrial DNA lineages. It seems that a single mtDNA haplotype almost completely dominates the maternal lineages of wild Siberian tigers. On the other hand, captive tigers appear to show higher mtDNA diversity. This may suggest that the subspecies has experienced a very recent genetic bottleneck caused by human pressure, with the founders of the captive population having been captured when genetic variability was higher in the wild.At the start of the 21st century, researchers from the University of Oxford, U.S. National Cancer Institute and Hebrew University of Jerusalem collected tissue samples from 20 of 23 Caspian tiger specimens kept in museums across Eurasia. They sequenced at least one segment of five mitochondrial genes and found a low amount of variability of the mitochondrial DNA in Caspian tigers as compared to other tiger subspecies. They re-assessed the phylogenetic relationships of tiger subspecies and observed a remarkable similarity between Caspian and Siberian tigers, indicating that the Siberian tiger is the genetically closest living relative of the Caspian tiger, which strongly implies a very recent common ancestry. Based on phylogeographic analysis, they suggested that the ancestor of Caspian and Siberian tigers colonized Central Asia less than 10,000 years ago via the Gansu−Silk Road region from eastern China, and subsequently traversed eastward to establish the Siberian tiger population in the Russian Far East. The events of the Industrial Revolution may have been the critical factor in the reciprocal isolation of Caspian and Siberian tigers from what was likely a single contiguous population.Samples of 95 wild Amur tigers were collected throughout their native range to investigate questions relative to population genetic structure and demographic history. Additionally, targeted individuals from the North American ex situ population were sampled to assess the genetic representation found in captivity. Population genetic and Bayesian structure analyses clearly identified two populations separated by a development corridor in Russia. Despite their well-documented 20th century decline, the researchers failed to find evidence of a recent population bottleneck, although genetic signatures of a historical contraction were detected. This disparity in signal may be due to several reasons, including historical paucity in population genetic variation associated with postglacial colonisation and potential gene flow from an extirpated Chinese population. The extent and distribution of genetic variation in captive and wild populations were similar, yet gene variants persisted ex situ that were lost in situ. Overall, their results indicate the need to secure ecological connectivity between the two Russian populations to minimize loss of genetic diversity and overall susceptibility to stochastic events, and support a previous study suggesting that the captive population may be a reservoir of gene variants lost in situ.In 2013, the whole genome of the Siberian tiger was sequenced and published. Tigers in mainland Asia fall into two clades: the northern clade comprises the Siberian and Caspian tiger populations, and the southern clade all remaining continental tiger populations. A study published in 2018 was based on 32 tiger specimens using a whole-genome sequencing for analysis. Results support six monophyletic tiger clades and indicate that the most recent common ancestor lived about 110,000 years ago.
+
+
+== Characteristics ==
+
+The tiger is reddish-rusty, or rusty-yellow in colour, with narrow black transverse stripes. The body length is not less than 150 cm (59 in), condylobasal length of skull 250 mm (9.8 in), zygomatic width 180 mm (7.1 in), and length of upper carnassial tooth over 26 mm (1.0 in) long. It has an extended supple body standing on rather short legs with a fairly long tail.
+
+
+=== Body size ===
+In the 1980s, the typical weight range of wild Siberian tigers was indicated as 180 to 306 kg (397 to 675 lb) for males and 100 to 167 kg (220 to 368 lb) for females. Exceptionally large individuals were targeted and shot by hunters.In 2005, a group of Russian, American and Indian zoologists published an analysis of historical and contemporary data on body weights of wild and captive tigers, both female and male across all subspecies. The data used include weights of tigers that were older than 35 months and measured in the presence of authors. Their comparison with historical data indicates that up to the first half of the 20th century both male and female Siberian tigers were on average heavier than post-1970 ones. The average historical wild male Siberian tiger weighed 215.3 kg (475 lb) and the female 137.5 kg (303 lb); the contemporary wild male Siberian tiger weighs 176.4 kg (389 lb) on average with an asymptotic limit being 222.3 kg (490 lb); a wild female weighs 117.9 kg (260 lb) on average. Historical Siberian tigers and Bengal tigers were the largest ones, whereas contemporary Siberian tigers are on average lighter than Bengal tigers. The reduction of the body weight of today's Siberian tigers may be explained by concurrent causes, namely the reduced abundance of prey because of illegal hunting and that the individuals were usually sick or injured and captured in a conflict situation with people.Measurements taken by scientists of the Siberian Tiger Project in the Sikhote-Alin range from 178 to 208 cm (70 to 82 in) in head and body length measured in straight line, with an average of 195 cm (77 in) for males; and for females ranging from 167 to 182 cm (66 to 72 in) with an average of 174 cm (69 in). The average tail measures 99 cm (39 in) in males and 91 cm (36 in) in females. The longest male measured 309 cm (122 in) in total length including a tail of 101 cm (40 in) and with a chest girth of 127 cm (50 in). The longest female measured 270 cm (110 in) in total length including tail of 88 cm (35 in) and with a chest girth of 108 cm (43 in).
+A male captured by members of the Siberian Tiger Project weighed 206 kg (454 lb), and the largest radio-collared male weighed 212 kg (467 lb).The Siberian tiger is often considered to be the largest tiger.
+A wild male, killed in Manchuria by the Sungari River in 1943, reportedly measured 350 cm (140 in) "over the curves", with a tail length of about 1 m (3 ft 3 in). It weighed about 300 kg (660 lb). Dubious sources mention weights of 318 and 384 kg (701 and 847 lb) and even 408 kg (899 lb).
+
+
+=== Skull ===
+The skull of the Siberian tiger is characterized by its large size. The facial region is very powerful and very broad in the region of the canines. The skull prominences, especially in the sagittal crest and crista occipitalis, are very high and strong in old males, and often much more massive than usually observed in the biggest skulls of Bengal tigers. The size variation in skulls of Siberian tigers ranges from 331 to 383 mm (13.0 to 15.1 in) in nine individuals measured. A female skull is always smaller and never as heavily built and robust as that of a male. The height of the sagittal crest in its middle part reaches as much as 27 mm (1.1 in), and in its posterior part up to 46 mm (1.8 in).Female skulls range from 279.7 to 310.2 mm (11.01 to 12.21 in). The skulls of male Caspian tigers from Turkestan had a maximum length of 297.0 to 365.8 mm (11.69 to 14.40 in), while that of females measured 195.7 to 255.5 mm (7.70 to 10.06 in). A tiger killed on the Sumbar River in Kopet Dag in January 1954 had a greatest skull length of 385 mm (15.2 in), which is considerably more than the known maximum for this population and slightly exceeds that of most Siberian tigers. However, its condylobasal length was only 305 mm (12.0 in), smaller than those of the Siberian tigers, with a maximum recorded condylobasal length of 342 mm (13.5 in). The biggest skull of a Siberian tiger from northeast China measured 406 mm (16.0 in) in length, which is about 20–30 mm (0.79–1.18 in) more than the maximum skull lengths of tigers from the Amur region and northern India, with the exception of a skull of a northern Indian tiger from the vicinity of Nagina, which measured 413 mm (16.25 in) "over the bone".
+
+
+=== Fur and coat ===
+
+The ground colour of Siberian tigers' pelage is often very pale, especially in winter coat. However, variations within populations may be considerable. Individual variation is also found in form, length, and partly in colour, of the dark stripes, which have been described as being dark brown rather than black.The fur of the Siberian tiger is moderately thick, coarse and sparse compared to that of other felids living in the former Soviet Union. Compared to the extinct westernmost populations, the Siberian tiger's summer and winter coats contrast sharply with other subspecies. Generally, the coat of western populations was brighter and more uniform than that of the Far Eastern populations. The summer coat is coarse, while the winter coat is denser, longer, softer, and silkier. The winter fur often appears quite shaggy on the trunk and is markedly longer on the head, almost covering the ears. Siberian and Caspian tigers had the thickest fur amongst tigers.The whiskers and hair on the back of the head and the top of the neck are also greatly elongated. The background colour of the winter coat is generally less bright and rusty compared to that of the summer coat. Because of the winter fur's greater length, the stripes appear broader with less defined outlines. The summer fur on the back is 15–17 mm (0.59–0.67 in) long, 30–50 mm (1.2–2.0 in) along the top of the neck, 25–35 mm (0.98–1.38 in) on the abdomen, and 14–16 mm (0.55–0.63 in) on the tail. The winter fur on the back is 40–50 mm (1.6–2.0 in), 70–110 mm (2.8–4.3 in) on the top of the neck, 70–95 mm (2.8–3.7 in) on the throat, 60–100 mm (2.4–3.9 in) on the chest and 65–105 mm (2.6–4.1 in) on the abdomen. The whiskers are 90–115 mm (3.5–4.5 in).
+
+
+== Distribution and habitat ==
+
+The Siberian tiger once inhabited much of the Korean Peninsula, Manchuria and other parts of north-eastern China, the eastern part of Siberia and the Russian Far East, perhaps as far west as Mongolia and the area of Lake Baikal, where the Caspian tiger also reportedly occurred.
+During the late Pleistocene and Holocene, it was likely connected to the South China tiger population through corridors in the Yellow River basin, before humans interrupted gene flow.Today, its range stretches south to north for almost 1,000 km (620 mi) the length of Primorsky Krai and into southern Khabarovsk Krai east and south of the Amur River. It also occurs within the Greater Xing'an Range, which crosses into Russia from China at several places in southwest Primorye. This region represents a merger zone of the East Asian temperate broadleaf and mixed forest and the taiga, resulting in a mosaic of forest types that vary in elevation and topography. Key habitats of the Siberian tiger are Korean pine forests with a complex composition and structure.The faunal complex of the region is represented by a mixture of Asian and boreal life forms. The ungulate complex is represented by seven species, with Manchurian wapiti, Siberian roe deer, and wild boar being the most common throughout the Sikhote-Alin mountains but rare in higher altitude spruce-fir forests. Sika deer are restricted to the southern half of the Sikhote-Alin mountains. Siberian musk deer and Amur moose are associated with the conifer forests and are near the southern limits of their distribution in the central Sikhote-Alin mountains.In 2005, the number of Amur tigers in China was estimated at 18–22, and 331–393 in the Russian Far East, comprising a breeding adult population of about 250, fewer than 100 likely to be sub-adults, more than 20 likely to be less than 3 years of age. More than 90% of the population occurred in the Sikhote Alin mountain region. An unknown number of tigers survive in the reserve areas around Baekdu Mountain, on the border between China and North Korea, based on tracks and sightings.In August 2012, a Siberian tiger with four cubs was recorded for the first time in northeastern China's Hunchun National Nature Reserve located in the vicinity of the international borders with Russia and North Korea. Camera-trap surveys carried out in the spring seasons of 2013 and 2014 revealed between 27 and 34 tigers along the China-Russian border.
+In April 2014, World Wide Fund for Nature personnel captured a video of a tigress with cubs in inland China.
+The tiger population in the Changbai Mountains dispersed westwards between 2003 and 2016.
+Camera trap surveys between 2013 and 2018 revealed about 55 Siberian tigers in four forested landscapes in northeastern China: Laoyeling, Zhangguangcai Range, Wandashan and Lesser Khingan Mountains. Feces, urine and hair was used to genetically identify 30 tigers in this region. However, only Laoyeling is thought to support a breeding population.
+
+
+== Ecology and behavior ==
+
+Siberian tigers are known to travel up to 1,000 km (620 mi) over ecologically unbroken country. In 1992 and 1993, the maximum total population density of the Sikhote-Alin tiger population was estimated at 0.62 tigers in 100 km2 (39 sq mi). The maximum adult population estimated in 1993 reached 0.3 tigers in 100 km2 (39 sq mi), with a sex ratio of averaging 2.4 females per male. These density values were much lower than what had been reported for other subspecies at the time.
+In 2004, dramatic changes in land tenure, population density, and reproductive output in the core area of the Sikhote-Alin Zapovednik Siberian Tiger Project were detected, suggesting that when tigers are well protected from human-induced mortality for long periods, the adult female population density increases significantly. When more adult females survived, the mothers shared their home ranges with their daughters once the daughters reached maturity. By 2007, population density of tigers was estimated at 0.8±0.4 tigers in 100 km2 (39 sq mi) in the southern part of Sikhote-Alin Zapovednik, and 0.6±0.3 tigers in 100 km2 (39 sq mi) in the central part of the protected area.Siberian tigers share habitat with Amur leopards (P. pardus orientalis), but in the Changbai Mountains have been recorded more often in lower elevations than leopards.
+
+
+=== Hunting and diet ===
+
+Prey species of the tiger include ungulates such as Manchurian wapiti (Cervus canadensis xanthopygus), Siberian musk deer  (Moschus moschiferus), long-tailed goral (Naemorhedus caudatus), moose (Alces alces), Siberian roe deer (Capreolus pygargus) and sika deer (Cervus nippon), wild boar (Sus scrofa), and even sometimes small size Asiatic black bears (Ursus thibetanus) and brown bears (Ursus arctos). Siberian tigers also take smaller prey like hares, rabbits, pikas and even salmon. Scat was collected along the international border between Russia and China between November 2014 and April 2015; 115 scat samples of nine tigers contained foremost remains of wild boar, sika deer and roe deer.Between January 1992 and November 1994, 11 tigers were captured, fitted with radio-collars and monitored for more than 15 months in the eastern slopes of the Sikhote-Alin mountain range. Results of this study indicate that their distribution is closely associated with distribution of Manchurian wapiti, while distribution of wild boar was not such a strong predictor for tiger distribution. Although they prey on both Siberian roe deer and sika deer, overlap of these ungulates with tigers was low. Distribution of moose was poorly associated with tiger distribution. The distribution of preferred habitat of key prey species was an accurate predictor of tiger distribution.Results of a three-year study on Siberian tigers indicate that the mean interval between their kills and estimated prey consumption varied across seasons: during 2009 to 2012, three adult tigers killed prey every 7.4 days in summer and consumed a daily average of 7.89 kg (17.4 lb); in winter they killed more large-bodied prey, made kills every 5.7 days and consumed a daily average of 10.3 kg (23 lb).
+
+
+=== Interspecific predatory relationships ===
+
+Following a decrease of ungulate populations from 1944 to 1959, more than 32 cases of Amur tigers attacking both Ussuri brown (Ursus arctos lasiotus) and Ussuri black bears (U. thibetanus ussuricus) were recorded in the Russian Far East, and hair of bears were found in several tiger scat samples. Tigers attack black bears less often than brown bears, as the latter live in more open habitats and are not able to climb trees. In the same time period, four cases of brown bears killing female tigers and young cubs were reported, both in disputes over prey and in self-defense. Tigers can tackle bears larger than themselves, using an ambushing tactic and jumping onto the bear from an overhead position, grabbing it by the chin with one forepaw and by the throat with the other, and then killing it with a bite in the spinal column. Tigers mainly feed on the bear's fat deposits, such as the back, hams and groin.When Amur tigers prey on brown bears, they usually target young and sub-adult bears, besides small female adults. Predation by tigers on denned brown bears was not detected during a study carried between 1993 and 2002. Ussuri brown bears, along with the smaller black bears constitute 2.1% of the Siberian tiger's annual diet, of which 1.4% are brown bears.The effect the presence of tigers has on brown bear behavior seems to vary. In the winters of 1970–1973, Yudakov and Nikolaev recorded two cases of bears showing no fear of tigers and another case of a brown bear changing path upon crossing tiger tracks. Other researchers have observed bears following tiger tracks to scavenge tiger kills and to potentially prey on tigers. Despite the threat of predation, some brown bears actually benefit from the presence of tigers by appropriating tiger kills that the bears may not be able to successfully hunt themselves. Brown bears generally prefer to contest the much smaller female tigers. During telemetry research in the Sikhote-Alin Nature Reserve, 44 direct confrontations between bears and tigers were observed, in which bears in general were killed in 22 cases, and tigers in 12 cases. There are reports of brown bears specifically targeting Amur leopards and tigers to abstract their prey. In the Sikhote-Alin reserve, 35% of tiger kills were stolen by bears, with tigers either departing entirely or leaving part of the kill for the bear. Some studies show that bears frequently track down tigers to usurp their kills, with occasional fatal outcomes for the tiger. A report from 1973 describes twelve known cases of brown bears killing tigers, including adult males; in all cases the tigers were subsequently eaten by the bears.The relationship between the Amur tiger and the Himalayan bear is not specifically studied. Numerous publications on these species there are mainly episodic and survey data on this issue are collected by different authors in selected areas which do not give a complete picture of the nature.Tigers depress wolf (Canis lupus) numbers, either to the point of localized extinction or to such low numbers as to make them a functionally insignificant component of the ecosystem. Wolves appear capable of escaping competitive exclusion from tigers only when human pressure decreases tiger numbers. In areas where wolves and tigers share ranges, the two species typically display a great deal of dietary overlap, resulting in intense competition. Wolf and tiger interactions are well documented in Sikhote-Alin, where until the beginning of the 20th century, very few wolves were sighted. Wolf numbers may have increased in the region after tigers were largely eliminated during the Russian colonisation in the late 19th century and early 20th century. This is corroborated by native inhabitants of the region claiming that they had no memory of wolves inhabiting Sikhote-Alin until the 1930s, when tiger numbers decreased. Today, wolves are considered scarce in tiger habitat, being found in scattered pockets, and usually seen travelling as loners or in small groups. First hand accounts on interactions between the two species indicate that tigers occasionally chase wolves from their kills, while wolves will scavenge from tiger kills. Tigers are not known to prey on wolves, though there are four records of tigers killing wolves without consuming them. Tigers recently released are also said to hunt wolves.This competitive exclusion of wolves by tigers has been used by Russian conservationists to convince hunters in the Far East to tolerate the big cats, as they limit ungulate populations less than wolves, and are effective in controlling wolf numbers.Siberian tigers also compete with the Eurasian lynx (Lynx lynx) and occasionally kill and eat them. Eurasian lynx remains have been found in the stomach contents of Siberian tigers in Russia. In March 2014, a dead lynx discovered in Bastak Nature Reserve bore evidence of predation by a Siberian tiger. The tiger apparently ambushed, pursued, and killed the lynx but only consumed it partially. This incident marks one of the first documented cases of a tiger preying on a lynx, and indicates that the tiger might have been more intent on eliminating a competitor than on catching prey.
+
+
+=== Reproduction and life cycle ===
+
+Siberian tigers mate at any time of the year. A female signals her receptiveness by leaving urine deposits and scratch marks on trees. She will spend 5 or 6 days with the male, during which she is receptive for three days. Gestation lasts from 3 to 3½ months. Litter size is normally two or four cubs but there can be as many as six. The cubs are born blind in a sheltered den and are left alone when the female leaves to hunt for food. Cubs are divided equally between sexes at birth. However, by adulthood there are usually two to four females for every male. The female cubs remain with their mothers longer, and later they establish territories close to their original ranges. Males, on the other hand, travel unaccompanied and range farther earlier in their lives, making them more vulnerable to poachers and other tigers.
+A Siberian tiger family comprising an adult male, a female and three cubs were recorded in 2015.At 35 months of age, tigers are sub-adults. Males reach sexual maturity at the age of 48 to 60 months.The average lifespan for Siberian tigers ranges from 16–18 years. Wild individuals tend to live between 10–15 years, while in captivity individuals may live up to 25 years.
+
+
+== Threats ==
+Results of genetic analysis of 95 wild Siberian tiger samples from Russia revealed that genetic diversity is low, only 27–35 individuals contributed to their genes. Further exacerbating the problem is that more than 90% of the population occurred in the Sikhote Alin mountain region. Tigers rarely move across the development corridor, which separates this sub-population from the much smaller sub-population in southwest Primorye province.The winter of 2006–2007 was marked by heavy poaching. Poaching of tigers and their wild prey species is considered to be driving the decline, although heavy snows in the winter of 2009 could have biased the data. In northern China’s Huang Ni He National Nature Reserve, poachers set up foremost snare traps, but there is not sufficient personnel to patrol this 75 km2 (29 sq mi) area throughout the year. In Hunchun National Nature Reserve, poaching of ungulate species impedes recovery of the tiger population.
+
+
+=== In the past ===
+After the dissolution of the Soviet Union, illegal deforestation and bribery of park rangers facilitated poaching of Siberian tigers. Local hunters had access to a formerly sealed off lucrative Chinese market, and this once again put the region's tiger population at risk of extinction. While improvement in the local economy has led to greater resources being invested in conservation efforts, an increase in economic activity has led to an increased rate of development and deforestation. The major obstacle in preserving the tiger is the enormous territory individual tigers require; up to 450 km2 (170 sq mi) is needed by a single female and more for a single male.The Siberian tiger was once common in the Korean Peninsula. It was eradicated during the period of Korea under Japanese rule between 1910 and 1945.
+
+
+== Conservation ==
+Tigers are included on CITES Appendix I, banning international trade. All tiger range states and countries with consumer markets have banned domestic trade as well. At the 14th Conference of the Parties to CITES in 2007, stronger enforcement measures were called for, as well as an end to tiger farming.In 1992, the Siberian Tiger Project was founded, with the aim of providing a comprehensive picture of the ecology of the Amur tiger and the role of tigers in the Russian Far East through scientific studies. By capturing and outfitting tigers with radio collars, their social structure, land use patterns, food habits, reproduction, mortality patterns and their relation with other inhabitants of the ecosystem, including humans is studied. These data compilations will hopefully contribute toward minimizing poaching threats because of traditional hunting. The Siberian Tiger Project has been productive in increasing local capacity to address human-tiger conflict with a Tiger Response Team, part of the Russian government's Inspection Tiger, which responds to all tiger-human conflicts; by continuing to enhance the large database on tiger ecology and conservation with the goal of creating a comprehensive Siberian tiger conservation plan; and training the next generation of Russian conservation biologists.
+In August 2010, China and Russia agreed to enhance conservation and cooperation in protected areas in a transboundary area for Amur tigers. China has undertaken a series of public awareness campaigns including celebration of the first Global Tiger Day in July 2010, and International Forum on Tiger Conservation and Tiger Culture and China 2010 Hunchun Amur Tiger Culture Festival in August 2010.
+
+
+=== Reintroduction ===
+
+Inspired by findings that the Amur tiger is the closest relative of the Caspian tiger, there has been discussion whether the Amur tiger could be an appropriate subspecies for reintroduction into a safe place in Central Asia. The Amu-Darya Delta was suggested as a potential site for such a project. A feasibility study was initiated to investigate if the area is suitable and if such an initiative would receive support from relevant decision makers. A viable tiger population of about 100 animals would require at least 5,000 km2 (1,900 sq mi) of large tracts of contiguous habitat with rich prey populations. Such habitat is not presently available in the delta and so cannot be provided in the short term. The proposed region is therefore unsuitable for the reintroduction, at least at this stage of development.
+
+A second possible introduction site in Kazakhstan is the Ili River delta at the southern edge of Lake Balkhash. The delta is situated between the Saryesik-Atyrau Desert and the Taukum Desert and forms a large wetland of about 8,000 km2 (3,100 sq mi). Until 1948, the delta was a refuge of the extinct Caspian tiger. Reintroduction of the Siberian tiger to the delta has been proposed. Large populations of wild boar inhabit the swamps of the delta. The reintroduction of the Bukhara deer, which was once an important prey, is under consideration. The Ili delta is therefore considered as a suitable site for introduction.In 2010, Russia exchanged two captive Siberian tigers for Persian leopards with the Iranian government, as conservation groups of both countries agreed on reintroducing these animals into the wild within the next five years. This issue is controversial since only 30% of such releases have been successful. In addition, the Siberian tiger is not genetically identical to the Caspian tiger. Another difference is the climatic, with temperatures higher in Iran than in Siberia. Introducing exotic species into a new habitat could inflict irreversible and unknown damage. In December 2010, one of the tigers exchanged died in Eram Zoo in Tehran. Nevertheless, the project has its defenders, and Iran has successfully reintroduced the Persian onager and Caspian red deer.In 2005, re-introduction was planned as part of the rewilding project at Pleistocene Park in the Kolyma River basin in northern Yakutia, Russia, provided the herbivore population has reached a size warranting the introduction of large predators.
+
+
+=== In captivity ===
+
+In recent years, captive breeding of tigers in China has accelerated to the point where the captive population of several tiger subspecies exceeds 4,000 animals. Three thousand specimens are reportedly held by 10–20 "significant" facilities, with the remainder scattered among some 200 facilities. This makes China home to the second largest captive tiger population in the world, after the U.S., which in 2005 had an estimated 4,692 captive tigers. In a census conducted by the U.S.-based Feline Conservation Federation, 2,884 tigers were documented as residing in 468 American facilities.In 1986, the Chinese government established the world's largest Siberian tiger breeding base, the Harbin Siberian Tiger Park, and was meant to build a Siberian tiger gene pool to ensure the genetic diversity of the tiger. The Park and its existing tiger population would be further divided into two parts, one as the protective species for genetic management and the other as the ornamental species. It was discovered that when the Heilongjiang Northeast Tiger Forest Park was founded it had only 8 tigers, but according to the current breeding rate of tigers at the park, the worldwide number of wild Siberian tigers will break through 1,000 in late 2010. South Korea expected to receive three tigers pledged for donation in 2009 by Russia in 2011.
+
+
+== Attacks on humans ==
+
+The Siberian tiger very rarely becomes a man-eater. Numerous cases of attacks on humans were recorded in the 19th century, occurring usually in central Asia excluding Turkmenistan, Kazakhstan and the Far East. Tigers were historically rarely considered dangerous unless provoked, though in the lower reaches of the Syr-Darya, a tiger reportedly killed a woman collecting firewood and an unarmed military officer whilst passing through reed thickets. Attacks on shepherds were recorded in the lower reaches of Ili. In the Far East, during the middle and late 19th century, attacks on people were recorded. In 1867 on the Tsymukha River, tigers killed 21 men and injured 6 others. In China's Jilin Province, tigers reportedly attacked woodsmen and coachmen, and occasionally entered cabins and dragged out both adults and children.
+
+According to the Japanese Police Bureau in Korea, in 1928 a tiger killed one human, whereas leopards killed three, wild boars four and wolves killed 48. Six cases were recorded in 20th century Russia of unprovoked attacks leading to man-eating behaviour. Provoked attacks are however more common, usually the result of botched attempts at capturing them. In December 1997, an injured Amur tiger attacked, killed and consumed two people. Both attacks occurred in the Bikin River valley. The anti-poaching task force Inspection Tiger investigated both deaths, tracked down and killed the tiger.In January 2002, a man was attacked by a tiger on a remote mountain road near Hunchun in Jilin province, China, near the borders of Russia and North Korea. He suffered compound fractures but managed to survive. When he sought medical attention, his story raised suspicions as Siberian tigers seldom attack humans. An investigation of the attack scene revealed that raw venison carried by the man was left untouched by the tiger. Officials suspected the man to be a poacher who provoked the attack. The following morning, tiger sightings were reported by locals along the same road, and a local TV station did an on-site coverage. The group found tiger tracks and blood spoor in the snow at the attack scene and followed them for approximately 2,500 meters, hoping to catch a glimpse of the animal. Soon, the tiger was seen ambling slowly ahead of them. As the team tried to get closer for a better camera view, the tiger suddenly turned and charged, causing the four to flee in panic. About an hour after that encounter, the tiger attacked and killed a 26-year-old woman on the same road. Authorities retrieved the body with the help of a bulldozer. By then, the tiger was found lying 20 meters away, weak and barely alive. It was successfully tranquilized and taken for examination, which revealed that the tiger was anemic and gravely injured by a poacher's snare around its neck, with the steel wire cutting deeply down to the vertebrae, severing both trachea and esophagus. Despite extensive surgery by a team of veterinarians, the tiger died of wound infection. Subsequent investigation revealed that the first victim was a poacher who set multiple snares that caught both the tiger and a deer. The man was later charged for poaching and harming endangered species. He served two years in prison. After being released from prison, he worked in clearing the forest of old snares.In an incident at the San Francisco Zoo in December 2007, a tiger escaped and killed a visitor, and injured two others. The animal was shot by the police. The zoo was widely criticized for maintaining only a 12.5 ft (3.8 m) fence around the tiger enclosure, while the international standard is 16 ft (4.9 m). The zoo subsequently erected a taller barrier topped by an electric fence. One of the victims admitted to taunting the animal.Zookeepers in Anhui province and the cities of Shanghai and Shenzhen were attacked and killed in 2010. In January 2011, a tiger attacked and killed a tour bus driver at a breeding park in Heilongjiang province. Park officials reported that the bus driver violated safety guidelines by leaving the vehicle to check on the condition of the bus. In September 2013, a tiger mauled a zookeeper to death at a zoo in western Germany after the worker forgot to lock a cage door during feeding time. In July 2020, a female tiger attacked and killed a 55-year-old zookeeper at the Zürich Zoo in Switzerland.
+
+
+== In culture ==
+
+The English name 'Siberian tiger' was coined by James Cowles Prichard in the 1830s. The name 'Amur tiger' was used in 1933 for Siberian tigers killed by the Amur River for an exhibition in the American Museum of Natural History.The Tungusic peoples considered the tiger a near-deity and often referred to it as "Grandfather" or "Old man". The Udege and Nani people call it "Amba". The Manchu considered the Siberian tiger as Hu Lin, the king. Since the tiger has a mark on its foreheads that looks like a Chinese character for 'King' (Chinese: 王; pinyin: Wáng), or a similar character meaning "Great Emperor", it is revered by the Udege and Chinese people.The Siberian tiger is used in heraldic symbols throughout the area where it is indigenous.
+A drawn Siberian tiger was the mascot of the 1981 Bandy World Championship, which was played in Khabarovsk in southeast Siberia.

+The Sumatran tiger is a population of Panthera tigris sondaica on the Indonesian island of Sumatra. It is the only surviving tiger population in the Sunda Islands, where the Bali and Javan tigers are extinct.Sequences from complete mitochondrial genes of 34 tigers support the hypothesis that Sumatran tigers are diagnostically distinct from mainland subspecies. In 2017, the Cat Classification Task Force of the Cat Specialist Group revised felid taxonomy and recognizes the living and extinct tiger populations in Indonesia as P. t. sondaica.
+
+
+== Taxonomy ==
+
+Felis tigris sondaicus was the scientific name proposed by Coenraad Jacob Temminck in 1844 for a tiger specimen from Java.Panthera tigris sumatrae was proposed by Reginald Innes Pocock in 1929, who described a skin and a skull of a tiger zoological specimen from Sumatra.
+The skull and pelage pattern of tiger specimens from Java and Sumatra do not differ significantly.P. t. sondaica is therefore considered the valid name for the living and extinct tiger populations in Indonesia.
+
+
+== Evolution ==
+Analysis of DNA is consistent with the hypothesis that Sumatran tigers became isolated from other tiger populations after a rise in sea level that occurred at the Pleistocene to Holocene border about 12,000–6,000 years ago. In agreement with this evolutionary history, the Sumatran tiger is genetically isolated from all living mainland tigers, which form a distinct group closely related to each other. The isolation of the Sumatran tiger from mainland tiger populations is supported by multiple unique characters, including two diagnostic mitochondrial DNA nucleotide sites, ten mitochondrial DNA haplotypes and 11 out of 108 unique microsatellite alleles. The relatively high genetic variability and the phylogenetic distinctiveness of the Sumatran tiger indicates that the gene flow between island and mainland populations was highly restricted.
+
+
+== Characteristics ==
+The Sumatran tiger was described based on two zoological specimens that differed in skull size and striping pattern from Bengal and Javan tiger specimens. It is darker in fur colour and has broader stripes than the Javan tiger. Stripes tend to dissolve into spots near their ends, and on the back, flanks and hind legs are lines of small, dark spots between the regular stripes. The frequency of stripes is higher than in other subspecies.
+Males have a prominent ruff, which is especially marked in the Sumatran tiger.The Sumatran tiger is one of the smallest tigers. Males measure between the pegs 2.2 to 2.55 m (87 to 100 in) in head-to-body length, with the greatest skull length of 295 to 335 mm (11.6 to 13.2 in) and weigh 100 to 140 kg (220 to 310 lb). Females weigh 75 to 110 kg (165 to 243 lb) and measure 2.15 to 2.30 m (85 to 91 in) in length between the pegs with a greatest length of skull of 263 to 294 mm (10.4 to 11.6 in).
+
+
+== Distribution and habitat ==
+The Sumatran tiger persists in small and fragmented populations across Sumatra, from sea level in the coastal lowland forest of Bukit Barisan Selatan National Park on the southeastern tip of Lampung Province to 3,200 m (10,500 ft) in mountain forests of Gunung Leuser National Park in Aceh Province. It is present in 27 habitat patches larger than 250 km2 (97 sq mi), which cover 140,226 km2 (54,142 sq mi). About a third of these patches are inside protected areas.Sumatran tigers prefer lowland and hill forests, where up to three tigers live in an area of 100 km2 (39 sq mi). They use non-forest habitats and human-dominated landscapes at the fringes of protected areas to a lesser degree.In 1978, the Sumatran tiger population was estimated at 1,000 individuals, based on responses to a questionnaire survey. In 1985, a total of 26 protected areas across Sumatra containing about 800 tigers were identified. In 1992, an estimated 400–500 tigers lived in five Sumatran national parks and two protected areas. At that time, the largest population unit comprised 110–180 individuals in Gunung Leuser National Park.
+As of 2011, the tiger population in Kerinci Seblat National Park in central Sumatra comprised 165–190 individuals, which is more than anywhere else on the island. The park has the highest tiger occupancy rate of Sumatra's protected areas, with 83% of the park showing signs of tigers.Sumatra's total tiger population was estimated at 618 ± 290 individuals in 2017.
+
+
+== Ecology and behaviour ==
+
+Sumatran tigers strongly prefer uncultivated forests and make little use of plantations of acacia and oil palm even if these are available. Within natural forest areas, they tend to use areas with higher elevation, lower annual rainfall, farther from the forest edge, and closer to forest centres. They prefer forest with dense understory cover and steep slope, and they strongly avoid forest areas with high human influence in the forms of encroachment and settlement. In acacia plantations, they tend to use areas closer to water and prefer areas with older plants, more leaf litter, and thicker subcanopy cover. Tiger records in oil palm plantations and rubber plantations are scarce. The availability of adequate vegetation cover at the ground level serves as an environmental condition fundamentally needed by tigers regardless of the location. Without adequate understory cover, tigers are even more vulnerable to persecution by humans. Human disturbance-related variables negatively affect tiger occupancy and habitat use. Variables with strong impacts include settlement and encroachment within forest areas, logging, and the intensity of maintenance in acacia plantations.Camera trapping surveys conducted in southern Riau revealed an extremely low abundance of potential prey and a low tiger density in peat swamp forest areas. Repeated sampling in the newly established Tesso Nilo National Park documented a trend of increasing tiger density from 0.90 individuals per 100 km2 (39 sq mi) in 2005 to 1.70 individuals per 100 km2 (39 sq mi) in 2008.In the Bukit Barisan Selatan National Park, nine prey species larger than 1 kg (2.2 lb) of body weight were identified including great argus, pig-tailed macaque, Malayan porcupine, Malayan tapir, banded pig, greater and lesser mouse-deer, Indian muntjac, and Sambar deer.
+
+
+== Threats ==
+
+Major threats include habitat loss due to expansion of palm oil plantations and planting of acacia plantations, prey-base depletion, and illegal trade primarily for the domestic market.Tigers need large contiguous forest blocks to thrive. Between 1985 and 1999, forest loss within Bukit Barisan Selatan National Park averaged 2% per year. A total of 661 km2 (255 sq mi) of forest disappeared inside the park, and 318 km2 (123 sq mi) were lost in a 10-km buffer, eliminating forest outside the park. Lowland forest disappeared faster than montane forest, and forests on gentle slopes disappeared faster than forests on steep slopes. Most forest conversions resulted from agricultural development, leading to predictions that by 2010, 70% of the park will be in agriculture. Camera-trap data indicated avoidance of forest boundaries by tigers. Classification of forest into core and peripheral forest based on mammal distribution suggests that by 2010, core forest area for tigers will be fragmented and reduced to 20% of the remaining forest.Sumatra's largest tiger population in Kerinci Seblat National Park is threatened by a high rate of deforestation in its outer regions. Drivers are an unsustainable demand for natural resources created by a human population with the highest rate of growth in Indonesia, and a government initiative to increase tree-crop plantations and high-intensity commercial logging, which ultimately leads to forest fires. The majority of the tigers found in the park were relocated to its center where conservation efforts are focused, but issues in the lowland hill forests of the outskirts remain. While being a highly suitable tiger habitat, these areas are also heavily targeted by logging efforts, which substantially contributes to declines in local tiger numbers.The expansion of plantations is increasing greenhouse gas emissions, playing a part in anthropogenic climate change, thus further adding to environmental pressures on endangered species. Climate-based movement of tigers northwards may lead to increased conflict with people. From 1987 to 1997, Sumatran tigers reportedly killed 146 people and at least 870 livestock. In West Sumatra, Riau, and Aceh, a total of 128 incidents were reported; 265 tigers were killed and 97 captured in response, and 35 more tigers were killed from 1998 to 2002. From 2007 to 2010, the tigers caused the death of 9 humans and 25 further tigers were killed.In 1997, an estimated 53 tigers were killed by poachers and their parts sold throughout most of northern Sumatra. Numbers for all of Sumatra are likely to be higher. Farmers killed many of the tigers to prevent livestock losses. They sold them to gold and souvenir shops, and pharmacies. In 2006, wildlife markets were surveyed in 28 cities and nine seaports in seven Sumatran provinces; 33 of 326 retail outlets offered tiger parts like skins, canines, bones, and whiskers. Tiger bones fetched the highest average price of US$116 per kg, followed by canines. There is evidence that tiger parts are smuggled out of Indonesia. In July 2005, over 140 kg (310 lb) of tiger bones and 24 skulls were confiscated in Taiwan in a shipment from Jakarta.In 2013–2014, Kerinci Seblat National Park experienced an upsurge in poaching, with the highest annual number of snare traps being removed for a patrol effort similar to previous years. Evidence is scarce and misunderstood on whether the strategies implemented to diminish poaching are succeeding despite the investment of millions of dollars annually into conservation strategies.
+
+
+== Conservation ==
+
+Panthera tigris is listed on CITES Appendix I. Hunting is prohibited in Indonesia.In 1994, the Indonesian Sumatran Tiger Conservation Strategy addressed the potential crisis that tigers faced in Sumatra. The Sumatran Tiger Project (STP) was initiated in June 1995 in and around the Way Kambas National Park to ensure the long-term viability of wild Sumatran tigers and to accumulate data on tiger life-history characteristics vital for the management of wild populations. By August 1999, the teams of the STP had evaluated 52 sites of potential tiger habitat in Lampung Province, of which only 15 were intact enough to contain tigers. In the framework of the STP, a community-based conservation programme was initiated to document the tiger-human dimension in the park to enable conservation authorities to resolve tiger-human conflicts based on a comprehensive database rather than anecdotes and opinions.In 2007, the Indonesian Forestry Ministry and Safari Park established cooperation with the Australia Zoo for the conservation of Sumatran tigers and other endangered species. The program includes conserving Sumatran tigers and other endangered species in the wild, efforts to reduce conflicts between tigers and humans, and rehabilitating Sumatran tigers and reintroducing them to their natural habitat.
+Indonesia's struggle with conservation has caused an upsurge in political momentum to protect and conserve wildlife and biodiversity. In 2009, Indonesia's president committed to substantially reduce deforestation, and policies across the nation requiring spatial plans that would be environmentally sustainable at national, provincial, and district levels.Between 2005 and 2015, about US$210 million have been invested into tiger law-enforcement activities that support forest ranger patrols, as well as the implementations of front-line law-enforcement activities by the Global Tiger Recovery Plan, which aims to double the number of wild tigers by 2020.
+In November 2016, Batu Nanggar Sanctuary was opened in North Padang Lawas Regency, North Sumatra
+for conservation of Sumatran wildlife.An interview survey among 600 consumers revealed that most were willing to pay consistently more for a "tiger-friendly" produced good if this product would be conducive to Sumatran tiger conservation.
+
+
+=== In captivity ===
+
+As of 2013, about 375 captive Sumatran tigers were listed in the global studbook and management plan, with 50 of them housed in 14 zoos in Australia and New Zealand. All of them were offspring of 15 founders. Fourteen cubs showed congenital vestibular system dysfunctions such as ataxia, strabismus, nystagmus, head tilting and falling that resolved when they were two years old. The cause for this disorder is most likely their close genetic relation and inbreeding.

+The tiger (Panthera tigris) is the largest living cat species and a member of the genus Panthera. It is most recognisable for its dark vertical stripes on orange fur with a white underside. An apex predator, it primarily preys on ungulates, such as deer and wild boar. It is territorial and generally a solitary but social predator, requiring large contiguous areas of habitat to support its requirements for prey and rearing of its offspring. Tiger cubs stay with their mother for about two years and then become independent, leaving their mother's home range to establish their own.
+The tiger was first scientifically described in 1758. It once ranged widely from the Eastern Anatolia Region in the west to the Amur River basin in the east, and in the south from the foothills of the Himalayas to Bali in the Sunda Islands. Since the early 20th century, tiger populations have lost at least 93% of their historic range and have been extirpated from Western and Central Asia, the islands of Java and Bali, and in large areas of Southeast and South Asia and China. What remains of the range where tigers still roam free is fragmented, stretching in spots from Siberian temperate forests to subtropical and tropical forests on the Indian subcontinent, Indochina and a single Indonesian island, Sumatra.
+The tiger is listed as Endangered on the IUCN Red List. As of 2015, the global wild tiger population was estimated to number between 3,062 and 3,948 mature individuals, with most populations living in small isolated pockets. India currently hosts the largest tiger population. Major reasons for population decline are habitat destruction, habitat fragmentation and poaching. Tigers are also victims of human–wildlife conflict, due to encroachment in countries with a high human population density.
+The tiger is among the most recognisable and popular of the world's charismatic megafauna. It featured prominently in the ancient mythology and folklore of cultures throughout its historic range and continues to be depicted in modern films and literature, appearing on many flags, coats of arms and as mascots for sporting teams. The tiger is the national animal of India, Bangladesh, Malaysia and South Korea.
+
+
+== Etymology ==
+The Middle English tigre and Old English tigras derive from Old French tigre, from Latin tigris.
+This was a borrowing of Classical Greek τίγρις 'tigris', a foreign borrowing of unknown origin meaning 'tiger' and the river Tigris.
+The origin may have been the Persian word tigra ('pointed or sharp') and the Avestan word tigrhi ('arrow'), perhaps referring to the speed of the tiger's leap, although these words are not known to have any meanings associated with tigers.The generic name Panthera is derived from the Latin word panthera and the Ancient Greek word πάνθηρ ('panther').
+
+
+== Taxonomy ==
+In 1758, Carl Linnaeus described the tiger in his work Systema Naturae and gave it the scientific name Felis tigris. In 1929, the British taxonomist Reginald Innes Pocock subordinated the species under the genus Panthera using the scientific name Panthera tigris.
+
+
+=== Subspecies ===
+
+Following Linnaeus's first descriptions of the species, several tiger specimens were described and proposed as subspecies. The validity of several tiger subspecies was questioned in 1999. Most putative subspecies described in the 19th and 20th centuries were distinguished on basis of fur length and colouration, striping patterns and body size, hence characteristics that vary widely within populations. Morphologically, tigers from different regions vary little, and gene flow between populations in those regions is considered to have been possible during the Pleistocene. Therefore, it was proposed to recognize only two tiger subspecies as valid, namely P. t. tigris in mainland Asia, and P. t. sondaica in the Greater Sunda Islands.Results of craniological analysis of 111 tiger skulls from Southeast Asian range countries indicate that Sumatran tiger skulls differ from Indochinese and Javan tiger skulls, whereas Bali tiger skulls are similar in size to Javan tiger skulls. The authors proposed to classify the Sumatran and Javan tigers as distinct species, P. sumatrae and P. sondaica, with the Bali tiger as subspecies P. sondaica balica.In 2015, morphological, ecological, and molecular traits of all putative tiger subspecies were analysed in a combined approach. Results support distinction of the two evolutionary groups continental and Sunda tigers. The authors proposed recognition of only two subspecies, namely P. t. tigris comprising the Bengal, Malayan, Indochinese, South Chinese, Siberian and Caspian tiger populations, and P. t. sondaica comprising the Javan, Bali and Sumatran tiger populations. The authors also noted that this reclassification will affect tiger conservation management. The nominate subspecies P. t. tigris constitutes two clades:
+a northern clade composed of the Siberian and Caspian tiger populations
+a southern clade composed of all other mainland populations.One conservation specialist welcomed this proposal as it would make captive breeding programmes and future rewilding of zoo-born tigers easier. One geneticist was sceptical of this study and maintained that the currently recognised nine subspecies can be distinguished genetically.In 2017, the Cat Classification Task Force of the IUCN Cat Specialist Group revised felid taxonomy and recognized the tiger populations in continental Asia as P. t. tigris, and those in the Sunda Islands as P. t. sondaica. This two-subspecies view has been largely rejected by researchers. Results of a 2018 whole-genome sequencing of 32 specimens support six monophyletic tiger clades corresponding with the living subspecies and indicate that the most recent common ancestor lived about 110,000 years ago.
+The following tables are based on the classification of the species Panthera tigris provided in Mammal Species of the World. It also reflects the classification used by the Cat Classification Task Force in 2017:
+
+
+=== Evolution ===
+
+The tiger's closest living relatives were previously thought to be the Panthera species lion, leopard and jaguar. Results of genetic analysis indicate that about 2.88 million years ago, the tiger and the snow leopard lineages diverged from the other Panthera species, and that both may be more closely related to each other than to the lion, leopard and jaguar.
+The geographic origin of the Panthera is most likely northern Central Asia. The tiger–snow leopard lineage dispersed in Southeast Asia during the Miocene.Panthera zdanskyi is considered to be a sister taxon of the modern tiger. It lived at the beginning of the Pleistocene about two million years ago, its fossil remains were excavated in Gansu of northwestern China. It was smaller and more "primitive", but functionally and ecologically similar to the modern tiger. It is disputed as to whether it had the striping pattern. Northwestern China is thought to be the origin of the tiger lineage. Tigers grew in size, possibly in response to adaptive radiations of prey species like deer and bovids, which may have occurred in Southeast Asia during the Early Pleistocene.Panthera tigris trinilensis lived about 1.2 million years ago and is known from fossils excavated near Trinil in Java. The Wanhsien, Ngandong, Trinil, and Japanese tigers became extinct in prehistoric times. Tigers reached India and northern Asia in the late Pleistocene, reaching eastern Beringia, Japan, and Sakhalin. Some fossil skulls are morphologically distinct from lion skulls, which could indicate tiger presence in Alaska during the last glacial period, about 100,000 years ago.Fossil teeth and bones found in Borneo were attributed to the Bornean tiger and date to about 13,745 to 3,000 years ago. It may have accessed Borneo, when the sea level was low during a glaciation period, and may have survived until about 200 years ago.
+In the Ille Cave on the island of Palawan, two articulated phalanx bones were found amidst an assemblage of other animal bones and stone tools. They were smaller than mainland tiger fossils, possibly due to insular dwarfism. It has been speculated that the tiger parts were either imported from elsewhere, or that the tiger colonised Palawan from Borneo before the Holocene. Fossil remains of tigers were also excavated in Sri Lanka, China, Japan and Sarawak dating to the Late Pliocene, Pleistocene and Early Holocene.Results of a phylogeographic study indicate that all living tigers had a common ancestor 108,000 to 72,000 years ago. The potential tiger range during the late Pleistocene and Holocene was predicted applying ecological niche modelling based on more than 500 tiger locality records combined with bioclimatic data. The resulting model shows a contiguous tiger range at the Last Glacial Maximum, indicating gene flow between tiger populations in mainland Asia. The Caspian tiger population was likely connected to the Bengal tiger population through corridors below elevations of 4,000 m (13,000 ft) in the Hindu Kush. The tiger populations on the Sunda Islands and mainland Asia were possibly separated during interglacial periods.The tiger's full genome sequence was published in 2013. It was found to have similar repeat composition to other cat genomes and an appreciably conserved synteny.
+
+
+=== Hybrids ===

+Captive tigers were bred with lions to create hybrids called liger and tigon. They share physical and behavioural qualities of both parent species. Breeding hybrids is now discouraged due to the emphasis on conservation.
+The liger is a cross between a male lion and a tigress. Ligers are typically between 10 and 12 ft (3.0 and 3.7 m) in length, and weigh between 800 and 1,000 lb (360 and 450 kg) or more. Because the lion sire passes on a growth-promoting gene, but the corresponding growth-inhibiting gene from the female tiger is absent, ligers grow far larger than either parent species.The less common tigon is a cross between a lioness and a male tiger. Because the male tiger does not pass on a growth-promoting gene and the lioness passes on a growth inhibiting gene, tigons are around the same size as their parents. Some females are fertile and have occasionally given birth to litigons when mated to a male Asiatic lion.

+
+== Description ==
+
+The tiger has a muscular body with strong forelimbs, a large head and a tail that is about half the length of its body. Its pelage colouration varies between shades of orange with a white underside and distinctive vertical black stripes; the patterns of which are unique in each individual. Stripes are likely advantageous for camouflage in vegetation such as long grass with strong vertical patterns of light and shade. The tiger is one of only a few striped cat species; it is not known why spotted patterns and rosettes are the more common camouflage pattern among felids. The orange colour may also aid in camouflage as the tiger's prey are dichromats, and thus may perceive the cat as green and blended in with the vegetation.A tiger's coat pattern is still visible when it is shaved. This is not due to skin pigmentation, but to the stubble and hair follicles embedded in the skin. It has a mane-like heavy growth of fur around the neck and jaws and long whiskers, especially in males. The pupils are circular with yellow irises. The small, rounded ears have a prominent white spot on the back, surrounded by black. These spots are thought to play an important role in intraspecific communication.The tiger's skull is similar to a lion's skull, with the frontal region usually less depressed or flattened, and a slightly longer postorbital region. The lion skull shows broader nasal openings. Due to the variation in skull sizes of the two species, the structure of the lower jaw is a reliable indicator for their identification. The tiger has fairly stout teeth; its somewhat curved canines are the longest among living felids with a crown height of up to 90 mm (3.5 in).
+
+
+=== Size ===
+There is notable sexual dimorphism between male and female tigers, with the latter being consistently smaller. The size difference between them is proportionally greater in the large tiger subspecies, with males weighing up to 1.7 times more than females. Males also have wider forepaw pads, enabling sex to be identified from tracks. It has been hypothesised that body size of different tiger populations may be correlated with climate and be explained by thermoregulation and Bergmann's rule, or by distribution and size of available prey species.Generally, males vary in total length from 250 to 390 cm (98 to 154 in) and weigh between 90 and 300 kg (200 and 660 lb) with skull length ranging from 316 to 383 mm (12.4 to 15.1 in). Females vary in total length from 200 to 275 cm (79 to 108 in), weigh 65 to 167 kg (143 to 368 lb) with skull length ranging from 268 to 318 mm (10.6 to 12.5 in). In either sex, the tail represents about 0.6 to 1.1 m (2 ft 0 in to 3 ft 7 in) of the total length. The Bengal and Siberian tigers are amongst the tallest cats in shoulder height. They are also ranked among the biggest cats that have ever existed reaching weights of more than 300 kg (660 lb). The tigers of the Sunda islands are smaller and less heavy than tigers in mainland Asia, rarely exceeding 142 kg (313 lb) in weight.
+
+
+=== Colour variations ===
+
+There are three other colour variants – white, golden and nearly stripeless snow white – that are now virtually non-existent in the wild due to the reduction of wild tiger populations, but continue in captive populations. The white tiger has white fur and sepia-brown stripes. The golden tiger has a pale golden pelage with a blond tone and reddish-brown stripes. The snow white tiger is a morph with extremely faint stripes and a pale reddish-brown ringed tail.  Both snow white and golden tigers are homozygous for CORIN gene mutations.The white tiger lacks pheomelanin (which creates the orange colour), and has dark sepia-brown stripes and blue eyes. This altered pigmentation is caused by a mutant gene that is inherited as an autosomal recessive trait, which is determined by a white locus. It is not an albino, as the dark pigments are scarcely affected. The mutation changes a single amino acid in the transporter protein SLC45A2. Both parents need to have the allele for whiteness to have white cubs.
+Between the early and mid 20th century, white tigers were recorded and shot in the Indian states of Odisha, Bihar, Assam and in the area of Rewa, Madhya Pradesh. The local maharaja started breeding tigers in the early 1950s and kept a white male tiger together with its normal-coloured daughter; they had white cubs.
+To preserve this recessive trait, only a few white individuals were used in captive breeding, which led to a high degree of inbreeding. Inbreeding depression is the main reason for many health problems of captive white tigers, including strabismus, stillbirth, deformities and premature death.
+Other physical defects include cleft palate and scoliosis.The Tiger Species Survival Plan has condemned the breeding of white tigers, alleging they are of mixed ancestry and of unknown lineage. The genes responsible for white colouration are represented by 0.001% of the population. The disproportionate growth in numbers of white tigers points to inbreeding among homozygous recessive individuals. This would lead to inbreeding depression and loss of genetic variability.There are also records of pseudomelanic or black tigers which have thick stripes that merge. In Simlipal National Park, 37% of the tiger population has this condition, which has been linked to isolation and inbreeding.
+
+
+== Distribution and habitat ==
+
+The tiger historically ranged from eastern Turkey and Transcaucasia to the coast of the Sea of Japan, and from South Asia across Southeast Asia to the Indonesian islands of Sumatra, Java and Bali. Since the end of the last glacial period, it was probably restricted by periods of deep snow lasting longer than six months. Currently, it occurs in less than 6% of its historical range, as it has been extirpated from Southwest and Central Asia, large parts of Southeast and East Asia. It now mainly occurs in the Indian subcontinent, the Indochinese Peninsula, Sumatra and the Russian Far East. In China and Myanmar, breeding populations appear to rely on immigration from neighbouring countries while its status in the Korean Peninsula is unknown.The tiger is essentially associated with forest habitats. Tiger populations thrive where populations of wild cervids, bovids and suids are stable.
+Records in Central Asia indicate that it occurred foremost in Tugay riverine forests along the Atrek, Amu Darya, Syr Darya, Hari, Chu and Ili Rivers and their tributaries. In the Caucasus, it inhabited hilly and lowland forests.
+Historical records in Iran are known only from the southern coast of the Caspian Sea and adjacent Alborz Mountains. In the Amur-Ussuri region, it inhabits Korean pine and temperate broadleaf and mixed forests, where riparian forests provide food and water, and serve as dispersal corridors for both tiger and ungulates.
+On the Indian subcontinent, it inhabits mainly tropical and subtropical moist broadleaf forests, moist evergreen forests, tropical dry forests and the swamp forests of the Sundarbans. In the Eastern Himalayas, tigers were documented in temperate forest up to an elevation of 4,200 m (13,800 ft) in Bhutan and of 3,630 m (11,910 ft) in the Mishmi Hills. In Myanmar, tigers are distributed across the country and among every province. The country is home to two tiger populations, Bengal and Indochinese tigers. In 1996, the composition of the two populations was 60% Bengal tigers and 40% Indochinese tigers. The natural ecological divide for these two populations is assumed to be the Irrawaddy River, but there is no scientific evidence for that hypothesis. DNA studies are needed to confirm it. Today, the presence of tigers was confirmed in the Hukawng Valley, Htamanthi Wildlife Sanctuary, and in two small areas in the Tanintharyi Region. The Tenasserim Hills is an important area, but forests are harvested there. In 2015, tigers were recorded by camera traps for the first time in the hill forests of Kayin State. In Thailand, it lives in deciduous and evergreen forests. In Laos, 14 tigers were documented in semi-evergreen and evergreen forest interspersed with grassland in Nam Et-Phou Louey National Protected Area during surveys from 2013 to 2017. In Sumatra, tiger populations range from lowland peat swamp forests to rugged montane forests.
+
+
+== Behaviour and ecology ==
+
+
+=== Social and daily activities ===
+When not subject to human disturbance, the tiger is mainly diurnal. It does not often climb trees but cases have been recorded. It is a strong swimmer and often bathes in ponds, lakes and rivers, thus keeping cool in the heat of the day. Individuals can cross rivers up to 7 km (4.3 mi) wide and can swim up to 29 km (18 mi) in a day. During the 1980s, a tiger was observed frequently hunting prey through deep lake water in Ranthambhore National Park.The tiger is a long-ranging species, and individuals disperse over distances of up to 650 km (400 mi) to reach tiger populations in other areas. Radio-collared tigers in Chitwan National Park started dispersing from their natal areas earliest at the age of 19 months. Four females dispersed between 0 and 43.2 km (0.0 and 26.8 mi), and 10 males between 9.5 and 65.7 km (5.9 and 40.8 mi). None of them crossed open cultivated areas that were more than 10 km (6.2 mi) wide, but moved through forested habitat.Adult tigers lead largely solitary lives. They establish and maintain territories but have much wider home ranges within which they roam. Resident adults of either sex generally confine their movements to their home ranges, within which they satisfy their needs and those of their growing cubs. Individuals sharing the same area are aware of each other's movements and activities. The size of the home range mainly depends on prey abundance, geographic area and sex of the individual. In India, home ranges appear to be 50 to 1,000 km2 (19 to 386 sq mi) while in Manchuria, they range from 500 to 4,000 km2 (190 to 1,540 sq mi). In Nepal, defended territories are recorded to be 19 to 151 km2 (7.3 to 58.3 sq mi) for males and 10 to 51 km2 (3.9 to 19.7 sq mi) for females.Young female tigers establish their first territories close to their mother's. The overlap between the female and her mother's territory reduces with time. Males, however, migrate further than their female counterparts and set out at a younger age to mark out their own area. A young male acquires territory either by seeking out an area devoid of other male tigers, or by living as a transient in another male's territory until he is older and strong enough to challenge the resident male. Young males seeking to establish themselves thereby comprise the highest mortality rate (30–35% per year) amongst adult tigers.
+
+To identify his territory, the male marks trees by spraying urine, anal gland secretions, marking trails with feces and marking trees or the ground with their claws. Females also use these "scrapes", urine and fecal markings. Scent markings of this type allow an individual to pick up information on another's identity, sex and reproductive status. Females in oestrus will signal their availability by scent marking more frequently and increasing their vocalisations.Although for the most part avoiding each other, tigers are not always territorial and relationships between individuals can be complex. An adult of either sex will sometimes share its kill with others, even with unrelated tigers. George Schaller observed a male share a kill with two females and four cubs. Unlike male lions, male tigers allow females and cubs to feed on the kill before the male is finished with it; all involved generally seem to behave amicably, in contrast to the competitive behaviour shown by a lion pride. Stephen Mills described a social feeding event in Ranthambore National Park:
+
+A dominant tigress they called Padmini killed a 250 kg (550 lb) male nilgai – a very large antelope. They found her at the kill just after dawn with her three 14-month-old cubs, and they watched uninterrupted for the next ten hours. During this period the family was joined by two adult females and one adult male, all offspring from Padmini's previous litters, and by two unrelated tigers, one female the other unidentified. By three o'clock there were no fewer than nine tigers round the kill.
+Male tigers are generally less tolerant of other males within their territories than females are of other females. Territory disputes are usually solved by intimidation rather than outright violence. Several such incidents have been observed in which the subordinate tiger yielded by rolling onto its back and showing its belly in a submissive posture. Once dominance has been established, a male may tolerate a subordinate within his range, as long as they do not live in too close quarters. The most serious disputes tend to occur between two males competing for a female in oestrus, sometimes fighting to the death.
+
+Facial expressions include the "defense threat", where an individual bares its teeth, flattens its ears and its pupils enlarge. Both males and females show a flehmen response, a characteristic grimace, when sniffing urine markings, but flehmen is more often associated with males detecting the markings made by tigresses in oestrus.Tigers roar to signal their presence to other individuals over long distances. This vocalization is forced through an open mouth as it closes and can be heard 3 km (1.9 mi) away. They may roar three or four times in a row, and other tigers may respond in kind. When tense, tigers will moan, a sound similar to a roar but softer and made when the mouth is at least partially closed. Moaning can be heard 400 m (1,300 ft) away. For aggressive encounters, tigers growl, snarl and hiss. During an attack, an explosive "coughing roar" or "coughing snarl" is emitted though an open mouth and exposed teeth. Chuffing—soft, low-frequency snorting similar to purring in smaller cats—is heard in more friendly situations. Other vocalizations include grunts, woofs and miaows.
+
+
+=== Hunting and diet ===
+
+In the wild, tigers mostly feed on large and medium-sized mammals, particularly ungulates weighing 60–250 kg (130–550 lb). Range-wide the most selected prey are sambar deer, Manchurian wapiti, barasingha and wild boar. Tigers are capable of taking down larger prey like adult gaur and wild water buffalo but will also opportunistically eat much smaller prey, such as monkeys, peafowl and other ground-based birds, hares, porcupines, and fish. They also prey on other predators, including dogs, leopards, pythons, bears, and crocodiles. Tigers generally do not prey on fully grown adult Asian elephants and Indian rhinoceros but incidents have been reported. More often, it is the more vulnerable small calves that are taken. When in close proximity to humans, tigers will also sometimes prey on such domestic livestock as cattle, horses, and donkeys. Although almost exclusively carnivorous, tigers will occasionally eat vegetation for dietary fibre such as fruit of the slow match tree.Tigers are thought to be mainly nocturnal predators, but in areas where humans are absent, remote-controlled, hidden camera traps recorded them hunting in daylight. They generally hunt alone and ambush their prey as most other cats do, overpowering them from any angle, using their body size and strength to knock the prey off balance. Successful hunts usually require the tiger to almost simultaneously leap onto its quarry, knock it over, and grab the throat or nape with its teeth. Despite their large size, tigers can reach speeds of about 49–65 km/h (30–40 mph) but only in short bursts; consequently, tigers must be close to their prey before they break cover. If the prey senses the tiger's presence before this, the tiger usually abandons the hunt rather than give chase or battle pre-alerted prey. Horizontal leaps of up to 10 m (33 ft) have been reported, although leaps of around half this distance are more typical. One in 2 to 20 hunts, including stalking near potential prey, ends in a successful kill.
+
+When hunting larger animals, tigers prefer to bite the throat and use their powerful forelimbs to hold onto the prey, often simultaneously wrestling it to the ground. The tiger remains latched onto the neck until its target dies of strangulation. By this method, gaurs and water buffaloes weighing over a ton have been killed by tigers weighing about a sixth as much. Although they can kill healthy adults, tigers often select the calves or infirm of very large species. Healthy adult prey of this type can be dangerous to tackle, as long, strong horns, legs and tusks are all potentially fatal to the tiger. No other extant land predator routinely takes on prey this large on its own.With small prey such as monkeys and hares, the tiger bites the nape, often breaking the spinal cord, piercing the windpipe, or severing the jugular vein or common carotid artery. Rarely, tigers have been observed to kill prey by swiping with their paws, which are powerful enough to smash the skulls of domestic cattle, and break the backs of sloth bears.After killing their prey, tigers sometimes drag it to conceal it in vegetation, grasping with their mouths at the site of the killing bite. This, too, can require great physical strength. In one case, after it had killed an adult gaur, a tiger was observed to drag the massive carcass over a distance of 12 m (39 ft). When 13 men simultaneously tried to drag the same carcass later, they were unable to move it. An adult tiger can go for up to two weeks without eating, then gorge on 34 kg (75 lb) of flesh at one time. In captivity, adult tigers are fed 3 to 6 kg (6.6 to 13.2 lb) of meat a day.
+
+
+=== Enemies and competitors ===
+
+Tigers usually prefer to eat self-killed prey, but eat carrion in times of scarcity and also steal prey from other large carnivores. Although predators typically avoid one another, if a prize is under dispute or a serious competitor is encountered, displays of aggression are common. If these fail, the conflicts may turn violent; tigers may kill or even prey on competitors such as leopards, dholes, striped hyenas, wolves, bears, pythons, and mugger crocodiles on occasion. Crocodiles, bears, and large packs of dholes may win conflicts with tigers, and crocodiles and bears can even kill them.The considerably smaller leopard avoids competition from tigers by hunting at different times of the day and hunting different prey. In India's Nagarhole National Park, most prey selected by leopards were from 30 to 175 kg (66 to 386 lb) against a preference for heavier prey by tigers. The average prey weight in the two respective big cats in India was 37.6 kg (83 lb) against 91.5 kg (202 lb). With relatively abundant prey, tigers and leopards were seen to successfully coexist without competitive exclusion or interspecies dominance hierarchies that may be more common to the African savanna, where the leopard lives beside the lion. Golden jackals may scavenge on tiger kills. Tigers appear to inhabit the deep parts of a forest while smaller predators like leopards and dholes are pushed closer to the fringes.
+
+
+=== Reproduction and life cycle ===
+
+The tiger mates all year round, but most cubs are born between March and June, with a second peak in September. Gestation ranges from 93 to 114 days, with an average of 103 to 105 days. A female is only receptive for three to six days. Mating is frequent and noisy during that time. The female gives birth in a sheltered location such as in tall grass, in a dense thicket, cave or rocky crevice. The father generally takes no part in rearing. Litters consist of two or three cubs, rarely as many as six. Cubs weigh from 780 to 1,600 g (28 to 56 oz) each at birth, and are born with eyes closed. They open their eyes when they are six to 14 days old. Their milk teeth break through at the age of about two weeks. They start to eat meat at the age of eight weeks. At around this time, females usually shift them to a new den. They make short ventures with their mother, although they do not travel with her as she roams her territory until they are older.  Females lactate for five to six months. Around the time they are weaned, they start to accompany their mother on territorial walks and are taught how to hunt.A dominant cub emerges in most litters, usually a male. The dominant cub is more active than its siblings and takes the lead in their play, eventually leaving its mother and becoming independent earlier. The cubs start hunting on their own earliest at the age of 11 months, and become independent around 18 to 20 months of age. They separate from their mother at the age of two to two and a half years, but continue to grow until the age of five years. Young females reach sexual maturity at three to four years, whereas males at four to five years. Unrelated wandering male tigers often kill cubs to make the female receptive, since the tigress may give birth to another litter within five months if the cubs of the previous litter are lost. The mortality rate of tiger cubs is about 50% in the first two years. Few other predators attack tiger cubs due to the diligence and ferocity of the mother. Apart from humans and other tigers, common causes of cub mortality are starvation, freezing, and accidents. Generation length of the tiger is about eight years.
+The oldest recorded captive tiger lived for 26 years.Occasionally, male tigers participate in raising cubs, usually their own, but this is extremely rare and not always well understood. In May 2015, Amur tigers were photographed by camera traps in the Sikhote-Alin Nature Reserve. The photos show a male Amur tiger pass by, followed by a female and three cubs within the span of about two minutes.
+In Ranthambore, a male Bengal tiger raised and defended two orphaned female cubs after their mother had died of illness. The cubs remained under his care, he supplied them with food, protected them from his rival and sister, and apparently also trained them.
+
+
+== Conservation ==
+
+In the 1990s, a new approach to tiger conservation was developed: Tiger Conservation Units (TCUs), which are blocks of habitat that have the potential to host tiger populations in 15 habitat types within five bioregions. Altogether 143 TCUs were identified and prioritized based on size and integrity of habitat, poaching pressure and population status. They range in size from 33 to 155,829 km2 (13 to 60,166 sq mi).In 2016, an estimate of a global wild tiger population of approximately 3,890 individuals was presented during the Third Asia Ministerial Conference on Tiger Conservation. The WWF subsequently declared that the world's count of wild tigers had risen for the first time in a century.Major threats to the tiger include habitat destruction, habitat fragmentation and poaching for fur and body parts, which have simultaneously greatly reduced tiger populations in the wild. In India, only 11% of the historical tiger habitat remains due to habitat fragmentation. Demand for tiger parts for use in traditional Chinese medicine has also been cited as a major threat to tiger populations. Some estimates suggest that there are fewer than 2,500 mature breeding individuals, with no subpopulation containing more than 250 mature breeding individuals.India is home to the world's largest population of wild tigers. A 2014 census estimated a population of 2,226, a 30% increase since 2011. On International Tiger Day 2019, the 'Tiger Estimation Report 2018' was released by Prime Minister Narendra Modi. The report estimates a population of 2967 tigers in India with 25% increase since 2014. Modi said "India is one of the safest habitats for tigers as it has achieved the target of doubling the tiger population from 1411 in 2011 to 2967 in 2019".
+As of 2022, India accounts for 75 percent of global tiger population.In 1973, India's Project Tiger, started by Indira Gandhi, established numerous tiger reserves. The project was credited with tripling the number of wild Bengal tigers from some 1,200 in 1973 to over 3,500 in the 1990s, but a 2007 census showed that numbers had dropped back to about 1,400 tigers because of poaching. Following the report, the Indian government pledged $153 million to the initiative, set up measures to combat poaching, promised funds to relocate up to 200,000 villagers in order to reduce human-tiger interactions, and set up eight new tiger reserves. India also reintroduced tigers to the Sariska Tiger Reserve and by 2009 it was claimed that poaching had been effectively countered at Ranthambore National Park.In the 1940s, the Siberian tiger was on the brink of extinction with only about 40 animals remaining in the wild in Russia. As a result, anti-poaching controls were put in place by the Soviet Union and a network of protected zones (zapovedniks) were instituted, leading to a rise in the population to several hundred. Poaching again became a problem in the 1990s, when the economy of Russia collapsed. The major obstacle in preserving the species is the enormous territory individual tigers require, up to 450 km (280 mi) needed by a single female and more for a single male. Current conservation efforts are led by local governments and NGO's in concert with international organisations, such as the World Wide Fund for Nature and the Wildlife Conservation Society. The competitive exclusion of wolves by tigers has been used by Russian conservationists to convince hunters to tolerate the big cats. Tigers have less impact on ungulate populations than do wolves, and are effective in controlling the latter's numbers. In 2005, there were thought to be about 360 animals in Russia, though these exhibited little genetic diversity. However, in a decade later, the Siberian tiger census was estimated from 480 to 540 individuals.In China, tigers became the target of large-scale 'anti-pest' campaigns in the early 1950s, where suitable habitats were fragmented following deforestation and resettlement of people to rural areas, who hunted tigers and prey species. Though tiger hunting was prohibited in 1977, the population continued to decline and is considered extinct in southern China since 2001. Having earlier rejected the Western-led environmentalist movement, China changed its stance in the 1980s and became a party to the CITES treaty. By 1993 it had banned the trade in tiger parts, and this diminished the use of tiger bones in traditional Chinese medicine. The Tibetan people's trade in tiger skins has also been a threat to tigers. The pelts were used in clothing, tiger-skin chuba being worn as fashion. In 2006 the 14th Dalai Lama was persuaded to take up the issue. Since then there has been a change of attitude, with some Tibetans publicly burning their chubas.
+
+In 1994, the Indonesian Sumatran Tiger Conservation Strategy addressed the potential crisis that tigers faced in Sumatra. The Sumatran Tiger Project (STP) was initiated in June 1995 in and around the Way Kambas National Park to ensure the long-term viability of wild Sumatran tigers and to accumulate data on tiger life-history characteristics vital for the management of wild populations. By August 1999, the teams of the STP had evaluated 52 sites of potential tiger habitat in Lampung Province, of which only 15 these were intact enough to contain tigers. In the framework of the STP a community-based conservation programme was initiated to document the tiger-human dimension in the park to enable conservation authorities to resolve tiger-human conflicts based on a comprehensive database rather than anecdotes and opinions.The Wildlife Conservation Society and Panthera Corporation formed the collaboration Tigers Forever, with field sites including the world's largest tiger reserve, the 21,756 km2 (8,400 sq mi) Hukaung Valley in Myanmar. Other reserves were in the Western Ghats in India, Thailand, Laos, Cambodia, the Russian Far East covering in total about 260,000 km2 (100,000 sq mi).Tigers have been studied in the wild using a variety of techniques. Tiger population have been estimated using plaster casts of their pugmarks, although this method was criticized as being inaccurate. More recent techniques include the use of camera traps and studies of DNA from tiger scat, while radio-collaring has been used to track tigers in the wild. Tiger spray has been found to be just as good, or better, as a source of DNA than scat.

+
+
+=== Tiger hunting ===
+
+The tiger has been one of the most sought after game animals of Asia. Tiger hunting took place on a large scale in the early 19th and 20th centuries, being a recognised and admired sport by the British in colonial India, the maharajas and aristocratic class of the erstwhile princely states of pre-independence India. A single maharaja or English hunter could claim to kill over a hundred tigers in their hunting career. Over 80,000 tigers were slaughtered in just 50 years spanning from 1875 to 1925 in British-ruled India. Tiger hunting was done by some hunters on foot; others sat up on machans with a goat or buffalo tied out as bait; yet others on elephant-back. King George V on his visit to Colonial India in 1911 killed 39 tigers in a matter of 10 days One of these is on display at the Royal Albert Memorial Museum.Historically, tigers have been hunted at a large scale so their famous striped skins could be collected. The trade in tiger skins peaked in the 1960s, just before international conservation efforts took effect. By 1977, a tiger skin in an English market was considered to be worth US$4,250.
+
+
+=== Body part use ===
+Tiger parts are commonly used as amulets in South and Southeast Asia. In the Philippines, the fossils in Palawan were found besides stone tools. This, besides the evidence for cuts on the bones, and the use of fire, suggests that early humans had accumulated the bones, and the condition of the tiger subfossils, dated to approximately 12,000 to 9,000 years ago, differed from other fossils in the assemblage, dated to the Upper Paleolithic. The tiger subfossils showed longitudinal fracture of the cortical bone due to weathering, which suggests that they had post-mortem been exposed to light and air. Tiger canines were found in Ambangan sites dating to the 10th to 12th centuries in Butuan, Mindanao.
+
+Many people in China and other parts of Asia have a belief that various tiger parts have medicinal properties, including as pain killers and aphrodisiacs. There is no scientific evidence to support these beliefs. The use of tiger parts in pharmaceutical drugs in China is already banned, and the government has made some offences in connection with tiger poaching punishable by death. Furthermore, all trade in tiger parts is illegal under the Convention on International Trade in Endangered Species of Wild Fauna and Flora and a domestic trade ban has been in place in China since 1993.However, the trading of tiger parts in Asia has become a major black market industry and governmental and conservation attempts to stop it have been ineffective to date. Almost all black marketers engaged in the trade are based in China and have either been shipped and sold within in their own country or into Taiwan, South Korea or Japan. The Chinese subspecies was almost completely decimated by killing for commerce due to both the parts and skin trades in the 1950s through the 1970s. Contributing to the illegal trade, there are a number of tiger farms in the country specialising in breeding them for profit. It is estimated that between 5,000 and 10,000 captive-bred, semi-tame animals live in these farms today. However, many tigers for traditional medicine black market are wild ones shot or snared by poachers and may be caught anywhere in the tiger's remaining range (from Siberia to India to the Malay Peninsula to Sumatra). In the Asian black market, a tiger penis can be worth the equivalent of around $300 U.S. dollars. In the years of 1990 through 1992, 27 million products with tiger derivatives were found. In July 2014 at an international convention on endangered species in Geneva, Switzerland, a Chinese representative admitted for the first time his government was aware trading in tiger skins was occurring in China.
+
+
+=== Man-eating tigers ===
+
+Wild tigers that have had no prior contact with humans actively avoid interactions with them. However, tigers cause more human deaths through direct attack than any other wild mammal. Attacks are occasionally provoked, as tigers lash out after being injured while they themselves are hunted. Attacks can be provoked accidentally, as when a human surprises a tiger or inadvertently comes between a mother and her young, or as in a case in rural India when a postman startled a tiger, used to seeing him on foot, by riding a bicycle. Occasionally tigers come to view people as prey. Such attacks are most common in areas where population growth, logging, and farming have put pressure on tiger habitats and reduced their wild prey. Most man-eating tigers are old, missing teeth, and unable to capture their preferred prey. For example, the Champawat Tiger, a tigress found in Nepal and then India, had two broken canines. She was responsible for an estimated 430 human deaths, the most attacks known to be perpetrated by a single wild animal, by the time she was shot in 1907 by Jim Corbett. According to Corbett, tiger attacks on humans are normally in daytime, when people are working outdoors and are not keeping watch. Early writings tend to describe man-eating tigers as cowardly because of their ambush tactics.Man-eaters have been a particular problem in recent decades in India and Bangladesh, especially in Kumaon, Garhwal and the Sundarbans mangrove swamps of Bengal, where some healthy tigers have hunted humans. Because of rapid habitat loss attributed to climate change, tiger attacks have increased in the Sundarbans. The Sundarbans area had 129 human deaths from tigers from 1969 to 1971. In the 10 years prior to that period, about 100 attacks per year in the Sundarbans, with a high of around 430 in some years of the 1960s. Unusually, in some years in the Sundarbans, more humans are killed by tigers than vice versa. In 1972, India's production of honey and beeswax dropped by 50% when at least 29 people who gathered these materials were devoured. In 1986 in the Sundarbans, since tigers almost always attack from the rear, masks with human faces were worn on the back of the head, on the theory that tigers usually do not attack if seen by their prey. This decreased the number of attacks only temporarily. All other means to prevent attacks, such as providing more prey or using electrified human dummies, did not work as well.
+
+
+=== In captivity ===
+
+In Ancient Roman times, tigers were kept in menageries and amphitheatres to be exhibited, trained and paraded, and were often provoked to fight gladiators and other exotic beasts. Since the 17th century, tigers, being rare and ferocious, were sought after to keep at European castles as symbols of their owners' power. Tigers became central zoo and circus exhibits in the 18th century: a tiger could cost up to 4,000 francs in France (for comparison, a professor of the Beaux-Arts at Lyons earned only 3,000 francs a year), or up to $3,500 in the United States, where a lion cost no more than $1,000.In 2007, over 4,000 captive tigers lived in China, of which 3,000 were held by about 20 larger facilities, with the rest held by some 200 smaller facilities. In 2011, 468 facilities in the USA kept 2,884 tigers. Nineteen US states banned private ownership of tigers, fifteen require a license, and sixteen states have no regulation. Genetic ancestry of 105 captive tigers from fourteen countries and regions showed that forty-nine animals belonged distinctly to five subspecies; fifty-two animals had mixed subspecies origins. Many Siberian tigers in zoos today are actually the result of crosses with Bengal tigers.
+
+
+== Cultural depictions ==
+
+Tigers and their superlative qualities have been a source of fascination for mankind since ancient times, and they are routinely visible as important cultural and media motifs. They are also considered one of the charismatic megafauna, and are used as the face of conservation campaigns worldwide. In a 2004 online poll conducted by cable television channel Animal Planet, involving more than 50,000 viewers from 73 countries, the tiger was voted the world's favourite animal with 21% of the vote, narrowly beating the dog.
+
+
+=== Mythology and legend ===
+
+In Chinese mythology and culture, the tiger is one of the 12 animals of the Chinese zodiac. In Chinese art, the tiger is depicted as an earth symbol and equal rival of the Chinese dragon – the two representing matter and spirit respectively. The Southern Chinese martial art Hung Ga is based on the movements of the tiger and the crane. In Imperial China, a tiger was the personification of war and often represented the highest army general (or present day defense secretary), while the emperor and empress were represented by a dragon and phoenix, respectively. The White Tiger (Chinese: 白虎; pinyin: Bái Hǔ) is one of the Four Symbols of the Chinese constellations. It is sometimes called the White Tiger of the West (Chinese: 西方白虎), and it represents the west and the autumn season.The tiger's tail appears in stories from countries including China and Korea, it being generally inadvisable to grasp a tiger by the tail. In Korean myth and culture, the tiger is regarded as a guardian that drives away evil spirits and a sacred creature that brings good luck – the symbol of courage and absolute power. For the people who live in and around the forests of Korea, the tiger considered the symbol of the Mountain Spirit or King of mountain animals. So, Koreans also called the tigers "San Gun" (산군) means Mountain Lord.In Buddhism, the tiger is one of the Three Senseless Creatures, symbolising anger, with the monkey representing greed and the deer lovesickness. The Tungusic peoples considered the Siberian tiger a near-deity and often referred to it as "Grandfather" or "Old man". The Udege and Nanai called it "Amba". The Manchu considered the Siberian tiger as "Hu Lin," the king. In Hinduism, the god Shiva wears and sits on tiger skin. The ten-armed warrior goddess Durga rides the tigress (or lioness) Damon into battle. In southern India the god Ayyappan was associated with a tiger. Dingu-Aneni is the god in North-East India is also associated with tiger. The weretiger replaces the werewolf in shapeshifting folklore in Asia; in India they were evil sorcerers, while in Indonesia and Malaysia they were somewhat more benign. In Greco-Roman tradition, the tiger was depicted being ridden by the god Dionysus.
+
+
+=== Literature and media ===
+
+In the Hindu epic Mahabharata, the tiger is fiercer and more ruthless than the lion. William Blake's poem in his Songs of Experience (1794), titled "The Tyger", portrays the tiger as a menacing and fearful animal. In Rudyard Kipling's 1894 The Jungle Book, the tiger Shere Khan is the mortal enemy of the human protagonist Mowgli. Yann Martel's 2001 Booker Prize winning novel Life of Pi, features the title character surviving shipwreck for months on a small boat with a large Bengal tiger while avoiding being eaten. The story was adapted in Ang Lee's 2012 feature film of the same name.Friendly tiger characters include Tigger in A. A. Milne's Winnie-the-Pooh and Hobbes of the comic strip Calvin and Hobbes, both represented as stuffed animals come to life. Tony the Tiger is a famous mascot for Kellogg's breakfast cereal Frosted Flakes, known for his catchphrase "They're Gr-r-reat!".
+
+
+=== Heraldry and emblems ===
+
+The tiger is one of the animals displayed on the Pashupati seal of the Indus Valley civilisation. The tiger was the emblem of the Chola Dynasty and was depicted on coins, seals and banners. The seals of several Chola copper coins show the tiger, the Pandyan emblem fish and the Chera emblem bow, indicating that the Cholas had achieved political supremacy over the latter two dynasties. Gold coins found in Kavilayadavalli in the Nellore district of Andhra Pradesh have motifs of the tiger, bow and some indistinct marks. The tiger symbol of Chola Empire was later adopted by the Liberation Tigers of Tamil Eelam and the tiger became a symbol of the unrecognised state of Tamil Eelam and Tamil independence movement. The Bengal tiger is the national animal of India and Bangladesh. The Malaysian tiger is the national animal of Malaysia. The Siberian tiger is the national animal of South Korea. The Tiger is featured on the logo of the Delhi Capitals IPL team.
+In European heraldry, the tyger, a depiction of a tiger as imagined by European artists, is among the creatures used in charges and supporters. This creature has several notable differences from real tigers, lacking stripes and having a leonine tufted tail and a head terminating in large, pointed jaws. A more realistic tiger entered the heraldic armory through the British Empire's expansion into Asia, and is referred to as the Bengal tiger to distinguish it from its older counterpart. The Bengal tiger is not a common creature in heraldry, but is used as a supporter in the arms of Bombay and emblazoned on the shield of the University of Madras.

+The hamadryas baboon (Papio hamadryas ) is a species of baboon within the Old World monkey family. It is the northernmost of all the baboons, being native to the Horn of Africa and the southwestern region of the Arabian Peninsula. These regions provide habitats with the advantage for this species of fewer natural predators than central or southern Africa where other baboons reside. The hamadryas baboon was a sacred animal to the ancient Egyptians and appears in various roles in ancient Egyptian religion, hence its alternative name of 'sacred baboon'.
+
+
+== Description ==
+Apart from the striking sexual dimorphism (males are nearly twice as large as females, which is common to most baboons) this species also shows differences in coloration among adults.  Adult males have a pronounced cape (mane and mantle), silver-white in color, which they develop around the age of ten, while the females are capeless and brown all over. Their faces range in color from reddish to tan to a dark brown.Males may have a body measurement of up to 80 cm (31 in) and weigh 20–30 kg (44–66 lb); females weigh 10–15 kg (22–33 lb) and have a body length of 40–45 cm (16–18 in). The tail adds a further 40–60 cm (16–24 in) to the length, and ends in a small tuft. Infants are very dark brown or black in coloration and lighten after about one year. Hamadryas baboons reach sexual maturity at about 4 years for females and between 5 to 7 years for males.
+
+
+== Local and indigenous names ==
+In Tigrinya language: ጋውና (gawina). In Arabic: الرُبَّاح (Al Robah).
+
+
+== Behaviour and ecology ==
+
+The Hamadryas baboon's range extends from the Red Sea in Eritrea to Ethiopia, Djibouti and Somalia. It is also native to the Sarawat Mountains of southwestern Arabia, in both Yemen and Saudi Arabia. It is locally extinct in Egypt. The hamadryas baboon lives in arid areas, savannas, and rocky areas, requiring cliffs for sleeping and finding water. Like all baboons, the hamadryas baboon is omnivorous and is adapted to its relatively dry habitat. During the wet seasons, the baboon feeds on a variety of foods, including blossoms, seeds, grasses, wild roots, bark and leaves from acacia trees. During the dry season, the baboons eat leaves of the Dobera glabra and sisal leaves. Hamadryas baboons also eat insects, spiders, worms, scorpions, reptiles, birds, and small mammals, including antelope.The baboon's drinking activities also depend on the season. During the wet seasons, the baboon do not have to go far to find pools of water. During the dry seasons, they frequent up to three permanent waterholes. Baboons rest at the waterholes during midafternoon and also dig drinking holes only a short distance from natural waterholes.
+
+
+=== Group organization ===
+
+The Hamadryas baboon has an unusual four-level social system called a multilevel society. Most social interaction occurs within small groups called one-male units or harems containing one male and up to 10 females, which the males lead and guard.  A harem often includes a younger "follower" male that may be related to the leader.  Two or more harems unite repeatedly to form clans.  Within clans, males are close relatives of one another and have an age-related dominance hierarchy.  Bands are the next level.  Two to four clans form bands of up to 400 individuals which usually travel and sleep as a group.  Males rarely leave their bands, and females are occasionally transferred or traded between bands by males. Bands may fight with one another over food or territory, and the adult male leaders of the units are the usual combatants. Bands also contain solitary males that are not harem leaders or followers and move freely within the band. Several bands may come together to form a troop, usually at sleeping cliffs.
+
+
+=== Group behavior ===
+
+The hamadryas baboon is unusual among baboon and macaque species in that its society is strictly patriarchal.  The males limit the movements of the females, herding them with visual threats and grabbing or biting any that wander too far away.  Males sometimes raid harems for females, resulting in aggressive fights. Many males succeed in taking a female from another's harem, called a "takeover".  Visual threats are usually accompanied by these aggressive fights. This would include a quick flashing of the eyelids accompanied by a yawn to show off the teeth. As in many species, infant baboons are taken by the males as hostages during fights. However, males within the same clan tend to be related and respect the social bonds of their kin. In addition, females demonstrate definite preferences for certain males, and rival males heed these preferences. The less a female favors her harem males, the more likely she will be successfully taken by a rival. Young males, often "follower" males, may start their own harems by maneuvering immature females into following them. The male may also abduct a young female by force. Either way, the male will mate with the female when she matures. Aging males often lose their females to followers and soon lose weight and their hair color changes to brown like a female. While males in most other baboon species are transferred away from their male relatives and into different troops, male hamadryas baboons remain in their natal clans or bands and have associations with their male kin.Hamadryas baboons have traditionally been thought of having a female transfer society with females being moved away from their relatives of the same sex. However, later studies show female baboons retain close associations with at least some female kin. Females can spend about as much time with other females as they do with the harem males, and some females will even interact with each other outside of their harems. In addition, it is not uncommon for females of the same natal group to end up in the same harem.  Females can still associate and help their extended families despite their interactions being controlled by the harem males.Females within a harem do not display any dominance relationships as seen in many other baboon and macaque species. The harem males suppress aggression between the females and prevent any dominance hierarchies from arising. Despite this, some social differences between the females occur. Some females are more socially active and have a stronger social bond with the harem male. These females, known as the "central females", stay in closer proximity to the harem male than the other females. Females that spend most of their time farther from the harem male are called "peripheral females".
+
+
+=== Reproduction and parenting ===
+
+Like other baboons, the hamadryas baboon breeds aseasonally. The dominant male of a one-male unit does most of the mating, though other males may occasionally sneak in copulations, as well.  Females do most of the parenting. They nurse and groom the infant and one female in a unit may groom an infant that is not hers. Like all baboons, hamadryas baboons are intrigued by infants and give much attention to them. Dominant male baboons prevent other males from coming into close contact with their infants. They also protect the young from predators. The dominant male tolerates the young and will carry and play with them. When a new male takes over a female, she develops sexual swellings which may be an adaptation that functions to prevent the new male from killing the offspring of the previous male. When males reach puberty, they show a playful interest in young infants.  They will kidnap the infants by luring them away from their harems and inviting them to ride on their backs. This is more often done by "follower" males. This kidnapping can lead to dehydration or starvation for the infant. The harem leader would retrieve the infants from their kidnappers, which is mostly an act to protect their offspring.
+
+
+=== Thermoregulation ===
+Because bipedalism is thought to help reduce thermoregulatory stress, research has investigated how baboons deal with water restriction and thermal loads as quadrupeds. Using implanted data loggers and simulated desert conditions, researchers found baboon internal temperatures increased significantly with water deprivation. When water was given to baboons, their internal temperatures dropped quickly. Therefore, it seems that access to water helps baboons maintain homeothermy and that water restrictions are a major threat to this species. However, baboons can maintain their plasma volume during water deprivation due to an increase in blood colloid osmotic pressure (COP). Hamadryas baboons do this by increasing albumin synthesis. This helps baboons retain fluids when their bodies are experiencing dehydration.
+
+
+== In culture ==
+
+Hamadryas baboons often appear in ancient Egyptian art, as they were considered sacred to Thoth, a major and powerful deity with many roles that included being the scribe of the gods. Astennu, attendant to Thoth, is represented as a hamadryas in his roles as recorder of the result of the Weighing of the Heart and as one of the four hamadryas baboons guarding the lake of fire in Duat, the ancient Egyptian underworld. A predynastic precursor to Astennu was Babi, or "Bull of the Baboons", a bloodthirsty god said to eat the entrails of the unrighteous dead. Babi was also said to give the righteous dead continued virility, and to use his penis as the mast of a boat to convey them to the Egyptian paradise.
+Sometimes, Thoth himself appears in the form of a hamadryas (often shown carrying the moon on his head), as an alternative to his more common representation as an ibis-headed figure. Hapi, one of the Four Sons of Horus that guarded the organs of the deceased in ancient Egyptian religion, is also represented as hamadryas-headed; Hapi protected the lungs, hence the common sculpting of a stone or clay hamadryas head as the lid of the canopic jar that held the lungs and/or represented the protection of the lungs. Hamadryas baboons were revered because certain behaviors that they perform were seen as worshiping the sun.
+
+
+=== Modern art ===
+The Grand Babouin sacré "hamadryas" is among Rembrandt Bugatti's most celebrated sculptures.
+
+
+== Threats and conservation ==
+Transformation of field and pastureland represents the main threat to the hamadryas baboon; its only natural predators are the striped hyena, spotted hyena, and a diminishing number of African leopards that can still be found in the same area of distribution. The IUCN Red List listed this species as "least concern" in 2008. No major range-wide threats exist at present, although locally it may be at risk through loss of habitat due to major agricultural expansion and irrigation projects. The species occurs in the proposed Yangudi Rassa National Park, the Harar Wildlife Sanctuary, and a number of wildlife reserves in the lower Awash valley and in northern Eritrea.

+The Harris's hawk (Parabuteo unicinctus), formerly known as the bay-winged hawk, dusky hawk, and sometimes a wolf hawk, and known in Latin America as peuco, is a medium-large bird of prey that breeds from the southwestern United States south to Chile, central Argentina, and Brazil. Birds are sometimes reported at large in Western Europe, especially Britain, but it is a popular species in falconry and these records almost invariably all refer to escapes from captivity.
+The name is derived from the Greek para, meaning beside, near or like, and the Latin buteo, referring to a kind of buzzard; uni meaning once; and cinctus meaning girdled, referring to the white band at the tip of the tail. John James Audubon gave this bird its English name in honor of his ornithological companion, financial supporter, and friend Edward Harris.The Harris's hawk is notable for its behavior of hunting cooperatively in packs consisting of tolerant groups, while other raptors often hunt alone. Harris hawks' social nature has been attributed to their intelligence, which makes them easy to train and have made them a popular bird for use in falconry.
+
+
+== Description ==
+
+This medium-large hawk is roughly intermediate in size between a peregrine falcon (Falco peregrinus) and a red-tailed hawk (Buteo jamaicensis). Harris's hawks range in length from 46 to 59 cm (18 to 23 in) and generally have a wingspan of about 103 to 120 cm (41 to 47 in). These hawks have a brownish plumage, reddish shoulders and tail feathers with a white base and white tip.They exhibit sexual dimorphism with the females being larger by about 35%. In the United States, the average weight for adult males is about 701 g (1.545 lb), with a range of 546 to 850 g (1.204 to 1.874 lb), while the adult female average is 1,029 g (2.269 lb), with a range of 766 to 1,633 g (1.689 to 3.600 lb). They have dark brown plumage with chestnut shoulders, wing linings, and thighs, white on the base and tip of the tail, long, yellow legs and a yellow cere. The vocalizations of the Harris's hawk are very harsh sounds.The lifespan of the Harris's Hawk is 10-–12 years in the wild, 20–25 years in captivity.
+
+
+=== Juvenile ===
+
+The juvenile Harris's hawk is mostly streaked with buff, and appears much lighter than the dark adults. When in flight, the undersides of the juveniles' wings are buff-colored with brown streaking. They can look unlike adults at first glance, but the identical chestnut plumage is an aid for identification.
+
+
+=== Subspecies ===
+There are three subspecies of the Harris's hawk:
+
+P. u. superior: found in Baja California, Arizona, Sonora, and Sinaloa. P. u. superior was believed to have longer tails and wings and to be more blackish than P. u. harrisi. However, the sample size of the original study was quite small, with only five males and six females. Later research has concluded that there is not as strong a physical difference as was originally assumed. Other ecological differences, such as latitudinal cline were also brought up as arguments against the validity of the subspecies segmentation.
+P. u. harrisi: found in Texas, eastern Mexico, and much of Central America.
+P. u. unicinctus: found exclusively in South America. It is smaller than the North American subspecies.
+
+
+== Distribution and habitat ==
+Harris's hawks live in sparse woodland and semi-desert, as well as marshes (with some trees) in some parts of their range (Howell and Webb 1995), including mangrove swamps, as in parts of their South American range. Harris's hawks are permanent residents and do not migrate. Important perches and nest supports are provided by scattered larger trees or other features (e.g., power poles, woodland edges, standing dead trees, live trees, and boulders, and saguaros).The wild Harris's hawk population is declining due to habitat loss; however, under some circumstances, they have been known to move into developed areas.
+
+
+== Behaviour ==
+This species occurs in relatively stable groups. A dominance hierarchy occurs in Harris's hawks, wherein the mature female is the dominant bird, followed by the adult male and then the young of previous years. Groups typically include from two to seven birds. Not only do birds cooperate in hunting, they also assist in the nesting process. No other bird of prey is known to hunt in groups as routinely as this species.
+
+
+=== Breeding ===
+
+They nest in small trees, shrubby growth, or cacti. The nests are often compact, made of sticks, plant roots, and stems, and are often lined with leaves, moss, bark and plant roots. They are built mainly by the female. There are usually two to four white to blueish white eggs sometimes with a speckling of pale brown or gray. The nestlings start out light buff, but in five to six days turn a rich brown.Very often, there will be three hawks attending one nest: two males and one female. Whether or not this is polyandry is debated, as it may be confused with backstanding (one bird standing on another's back). The female does most of the incubation. The eggs hatch in 31 to 36 days. The young begin to explore outside the nest at 38 days, and fledge, or start to fly, at 45 to 50 days. The female sometimes breeds two or three times in a year. Young may stay with their parents for up to three years, helping to raise later broods. Nests are known to be predated by coyotes (Canis latrans), golden eagles (Aquila chrysaetos), red-tailed hawks (Buteo jamaicensis), great horned owls (Bubo virginianus) and flocks of common ravens (Corvus corax), predators possibly too formidable to be fully displaced by the Harris's hawk's cooperative nest defenses. No accounts show predation on adults in the United States and the Harris's hawk may be considered an apex predator, although presumably predators like eagles and great horned owls would be capable of killing them. In Chile, black-chested buzzard-eagles (Geranoaetus melanoleucus) are likely predators.
+
+
+=== Feeding ===
+
+The diet of the Harris's hawk consists of small creatures including birds, lizards, mammals, and large insects. Because it often hunts in groups, the Harris's hawk can also take down larger prey. Although not particularly common, the Harris's hawk may take prey weighing over 2 kg (4.4 lb), such as adult jackrabbits, great blue heron (Ardea herodias) and half-grown wild turkeys (Meleagris gallapavo). The desert cottontail (Syvilagus auduboni), the leading prey species in the north of the Harris's hawk's range, usually weighs 800 g (1.8 lb) or less. Undoubtedly because it pursues large prey often, this hawk has larger and stronger feet, with long talons, and a larger, more prominent hooked beak than most other raptors around its size. Locally, other buteonine hawks, including the ferruginous hawk, the red-tailed hawk and the white-tailed hawk also hunt primarily cottontails and jackrabbits, but each are bigger, weighing about 500 g (18 oz), 300 g (11 oz) and 200 g (7.1 oz), respectively, more on average than a Harris's hawk.In the Southwestern United States, the most common prey species (in descending order of prevalence) are desert cottontail (Syvilagus auduboni), eastern cottontail (Syvilagus floridanus), black-tailed jackrabbit (Lepus californicus), ground squirrels (Ammopsermophilus spp. and Spermophilus spp.), woodrats (Neotoma spp.), kangaroo rats (Dipodomys spp.), pocket gophers (Geomys and Thomomys spp.), Gambel's quail (Callipepla gambelii), scaled quail (C. squamata), northern bobwhite (Colinus virginianus), cactus wren (Campylorhynchus brunneicapillus), northern mockingbird (Mimus polyglottos), desert spiny lizards (Sceloporus magister), and skinks (Eumeces spp.) In the tropics, Harris's hawks have adapted to taking prey of several varieties, including those like chickens and European rabbits introduced by man. In Chile, the common degu (Octodon degus) makes up 67.5% of the prey.
+
+
+=== Hunting ===
+While most raptors are solitary, only coming together for breeding and migration, Harris's hawks will hunt in cooperative groups of two to six. This is believed to be an adaptation to the lack of prey in the desert climate in which they live. In one hunting technique, a small group flies ahead and scouts, then another group member flies ahead and scouts, and this continues until prey is bagged and shared. In another, all the hawks spread around the prey and one bird flushes it out. Harris's hawks will often chase prey on foot, and are quite fast on the ground and their long, yellow legs are adapted for this, as most hawks don't spend as much time on the ground. Groups of Harris's hawks tend to be more successful at capturing prey than lone hawks, with groups of two to four individuals having ~10% higher success rates per extra individual.
+
+
+== Relationship with humans ==
+
+
+=== Falconry ===
+Since about 1980, Harris's hawks have been increasingly used in falconry and are now the most popular hawks in the West (outside of Asia) for that purpose, as they are one of the easiest to train and the most social.Trained Harris's hawks have been used to remove an unwanted pigeon population from London's Trafalgar Square, and from the tennis courts at Wimbledon.Trained Harris's hawks have  been used for bird abatement by falconry experts in Canada and the United States at various locations including airports, resorts, landfill sites, and industrial sites.
+

+
+=== In art ===
+John James Audubon illustrated the Harris's hawk in The Birds of America (published in London, 1827–38) as Plate 392 with the title "Louisiana Hawk -Buteo harrisi". The image was engraved and colored by the Robert Havell, London workshops in 1837. The original watercolor by Audubon was purchased by the New York History Society where it remains to this day (January 2009).

+The genus Pauxi consists of the three species of helmeted curassows, terrestrial black fowl with ornamental casque on their heads. All are found in South America.
+This genus contains 3 species
+
+As indicated by analysis of mt and nDNA sequences and calibrated with geological data, this genus' ancestors probably diverged from those of Mitu, their closest living relatives, in the Tortonian (early Late Miocene), some 8–7.4 mya. How the present distribution in 4 small areas quite distant from each other came to be is not known. Given that helmeted curassows are birds of the foothills and uplands, it might be that the ancestral Pauxi population became fragmented by the uplift of the Andes, which in their area of distribution took place during the Late Miocene, around the Pauxi-Mitu divergence and some time after.(Pereira & Baker 2002, Pereira et al. 2002).
+Pereira & Baker (2002) reported an interesting find: in the mtDNA phylogeny, Pauxi was paraphyletic, with P. unicornis being resolved as the sister species of Mitu tuberosa. This, of course, does not automatically imply that they are closely related or that the genera are invalid. Rather, the authors point out, given the distinct and peculiar morphology of the two genera, incomplete lineage sorting or hybridization between ancestral individuals of the two species is a more likely explanation. According to their data, there must have been some extent of gene flow between Mitu tuberosa and P. unicornis around 2 mya. Unfortunately, the authors do not provide subspecific identification of their single P. unicornis specimen. In any case, they took care to exclude captive hybridization in their choice of samples, as it is frequently known to occur in curassows and would have confounded the analysis. Altogether, what can be said with certainty is that there seems to have been some extent of hybridization between at least one population of the southern helmeted curassow and female razor-billed curassows at the end of the Pliocene.

+The Indian peafowl (Pavo cristatus), also known as the common peafowl, and blue peafowl, is a peafowl species native to the Indian subcontinent. It has been introduced to many other countries.  Male peafowl are referred to as peacocks, and female peafowl are referred to as peahens, even though peafowl of either sex are often referred to colloquially as "peacocks".Indian peafowl display a marked form of sexual dimorphism. The peacock is brightly coloured, with a predominantly blue fan-like crest of spatula-tipped wire-like feathers and is best known for the long train made up of elongated upper-tail covert feathers which bear colourful eyespots. These stiff feathers are raised into a fan and quivered in a display during courtship. Despite the length and size of these covert feathers, peacocks are still capable of flight. Peahens lack the train, have a white face and iridescent green lower neck, and dull brown plumage. The Indian peafowl lives mainly on the ground in open forest or on land under cultivation where they forage for berries, grains but also prey on snakes, lizards, and small rodents. Their loud calls make them easy to detect, and in forest areas often indicate the presence of a predator such as a tiger. They forage on the ground in small groups and usually try to escape on foot through undergrowth and avoid flying, though they fly into tall trees to roost.
+The function of the peacock's elaborate train has been debated for over a century. In the 19th century, Charles Darwin found it a puzzle, hard to explain through ordinary natural selection. His later explanation, sexual selection, is widely but not universally accepted. In the 20th century, Amotz Zahavi argued that the train was a handicap, and that males were honestly signalling their fitness in proportion to the splendour of their trains. Despite extensive study, opinions remain divided on the mechanisms involved.
+The bird is celebrated in Hindu and Greek mythology and is the national bird of India. The Indian peafowl is listed as of Least Concern on the IUCN Red List.
+
+
+== Taxonomy and naming ==
+Carl Linnaeus in his work Systema Naturae in 1758 assigned to the Indian peafowl the technical name of Pavo cristatus (means "crested peafowl" in classical Latin).
+The earliest usage of the word in written English is from around 1300 and spelling variants include pecok, pekok, pecokk, peacocke, peacock, pyckock, poucock, pocok, pokok, pokokke, and poocok among others. The current spelling was established in the late 17th century. Chaucer (1343–1400) used the word to refer to a proud and ostentatious person in his simile "proud a pekok" in Troilus and Criseyde (Book I, line 210).The Greek word for peacock was taos and was related to the Persian "tavus" (as in Takht-i-Tâvus for the famed Peacock Throne). The Ancient Hebrew word tuki (plural tukkiyim) has been said to have been derived from the Tamil tokei but sometimes traced to the Egyptian tekh. In modern Hebrew the word for peacock is "tavas". In Sanskrit, the peacock is known as Mayura and is associated with the killing of snakes.
+
+
+== Description ==
+Peacocks are a larger sized bird with a length from bill to tail of 100 to 115 cm (39 to 45 in) and to the end of a fully grown train as much as 195 to 225 cm (77 to 89 in) and weigh 4–6 kg (8.8–13.2 lb). The females, or peahens, are smaller at around 95 cm (37 in) in length and weigh 2.75–4 kg (6.1–8.8 lb). Indian peafowl are among the largest and heaviest representatives of the Phasianidae. So far as is known, only the wild turkey grows notably heavier. The green peafowl is slightly lighter in body mass despite the male having a longer train on average than the male of the Indian species. Their size, colour and shape of crest make them unmistakable within their native distribution range. The male is metallic blue on the crown, the feathers of the head being short and curled. The fan-shaped crest on the head is made of feathers with bare black shafts and tipped with bluish-green webbing. A white stripe above the eye and a crescent shaped white patch below the eye are formed by bare white skin. The sides of the head have iridescent greenish blue feathers. The back has scaly bronze-green feathers with black and copper markings. The scapular and the wings are buff and barred in black, the primaries are chestnut and the secondaries are black. The tail is dark brown and the "train" is made up of elongated upper tail coverts (more than 200 feathers, the actual tail has only 20 feathers) and nearly all of these feathers end with an elaborate eye-spot. A few of the outer feathers lack the spot and end in a crescent shaped black tip. The underside is dark glossy green shading into blackish under the tail. The thighs are buff coloured. The male has a spur on the leg above the hind toe.
+The adult peahen has a rufous-brown head with a crest as in the male but the tips are chestnut edged with green. The upper body is brownish with pale mottling. The primaries, secondaries and tail are dark brown. The lower neck is metallic green and the breast feathers are dark brown glossed with green. The remaining underparts are whitish. Downy young are pale buff with a dark brown mark on the nape that connects with the eyes. Young males look like the females but the wings are chestnut coloured.The most common calls are a loud pia-ow or may-awe. The frequency of calling increases before the Monsoon season and may be delivered in alarm or when disturbed by loud noises. In forests, their calls often indicate the presence of a predators such as the tiger. They also make many other calls such as a rapid series of ka-aan..ka-aan or a rapid kok-kok. They often emit an explosive low-pitched honk! when agitated.
+
+
+=== Mutations and hybrids ===
+
+There are several colour mutations of Indian peafowl. These very rarely occur in the wild, but selective breeding has made them common in captivity. The black-shouldered or Japanned mutation was initially considered as a subspecies of the Indian peafowl (P. c. nigripennis) (or even a separate species (P. nigripennis)) and was a topic of some interest during Darwin's time. It is, however, only a case of genetic variation within the population. In this mutation, the adult male is melanistic with black wings. Young birds with the nigripennis mutation are creamy white with fulvous-tipped wings. The gene produces melanism in the male and in the peahen it produces a dilution of colour with creamy white and brown markings. Other forms include the pied and white mutations, all of which are the result of allelic variation at specific loci.Crosses between a male green peafowl (Pavo muticus) and a female Indian peafowl (P. cristatus) produce a stable hybrid called a "Spalding", named after Mrs. Keith Spalding, a bird fancier in California. There can be problems if birds of unknown pedigree are released into the wild, as the viability of such hybrids and their offspring is often reduced (see Haldane's rule and outbreeding depression).
+
+
+== Distribution and habitat ==
+
+The Indian peafowl is a resident breeder across the Indian subcontinent and inhabits the drier lowland areas of Sri Lanka. In the Indian subcontinent, it is found mainly below an elevation of 1,800 m (5,900 ft) and in rare cases seen at about 2,000 m (6,600 ft). It is found in moist and dry-deciduous forests, but can adapt to live in cultivated regions and around human habitations and is usually found where water is available. In many parts of northern India, they are protected by religious practices and will forage around villages and towns for scraps. Some have suggested that the peacock was introduced into Europe by Alexander the Great, while others say the bird had reached Athens by 450 BCE and may have been introduced even earlier. It has since been introduced in many other parts of the world and has become feral in some areas.The Indian peafowl has been introduced to the United States, the United Kingdom, Mexico, Honduras, Costa Rica, Colombia, Guyana, Suriname, Brazil, Uruguay, Argentina, South Africa, Spain, Portugal, Madagascar, Mauritius, Réunion, Indonesia, Papua New Guinea, Australia, New Zealand, Croatia and the island of Lokrum.
+
+
+== Genome sequencing ==
+The first whole-genome sequencing of Indian peafowl identified a total of 15,970 protein-coding sequences, along with 213 tRNAs, 236 snoRNAs, and 540 miRNAs. The peacock genome was found to have less repetitive DNA (8.62%) than that of the chicken genome (9.45%). PSMC analysis suggested that the peacock suffered at least two bottlenecks (around four million years ago and again 450,000 years ago), which resulted in a severe reduction in its effective population size.
+
+
+== Behaviour and ecology ==
+Peafowl are best known for the male's extravagant display feathers which, despite actually growing from their back, are thought of as a tail. The "train" is in reality made up of the enormously elongated upper tail coverts. The tail itself is brown and short as in the peahen. The colours result not from any green or blue pigments but from the micro-structure of the feathers and the resulting optical phenomena. The long train feathers (and tarsal spurs) of the male develop only after the second year of life. Fully developed trains are found in birds older than four years. In northern India, these begin to develop each February and are moulted at the end of August. The moult of the flight feathers may be spread out across the year.Peafowl forage on the ground in small groups, known as musters, that usually have a cock and 3 to 5 hens. After the breeding season, the flocks tend to be made up only of females and young. They are found in the open early in the mornings and tend to stay in cover during the heat of the day. They are fond of dust-bathing and at dusk, groups walk in single file to a favourite waterhole to drink. When disturbed, they usually escape by running and rarely take to flight.Peafowl produce loud calls especially in the breeding season. They may call at night when alarmed and neighbouring birds may call in a relay like series. Nearly seven different call variants have been identified in the peacocks apart from six alarm calls that are commonly produced by both sexes.Peafowl roost in groups during the night on tall trees but may sometimes make use of rocks, buildings or pylons. In the Gir forest, they chose tall trees in steep river banks. Birds arrive at dusk and call frequently before taking their position on the roost trees. Due to this habit of congregating at the roost, many population studies are made at these sites. The population structure is not well understood. In a study in northern India (Jodhpur), the number of males was 170–210 for 100 females but a study involving evening counts at the roost site in southern India (Injar) suggested a ratio of 47 males for 100 females.
+
+
+=== Sexual selection ===
+
+The colours of the peacock and the contrast with the much duller peahen were a puzzle to early thinkers. Charles Darwin wrote to Asa Gray that the "sight of a feather in a peacock's tail, whenever I gaze at it, makes me sick!" as he failed to see an adaptive advantage for the extravagant tail which seemed only to be an encumbrance. Darwin developed a second principle of sexual selection to resolve the problem, though in the prevailing intellectual trends of Victorian Britain, the theory failed to gain widespread attention.The American artist Abbott Handerson Thayer tried to show, from his own imagination, the value of the eyespots as disruptive camouflage in a 1907 painting. He used the painting in his 1909 book Concealing-Coloration in the Animal Kingdom, denying the possibility of sexual selection and arguing that essentially all forms of animal colouration had evolved as camouflage. He was roundly criticised in a lengthy paper by Theodore Roosevelt, who wrote that Thayer had only managed to paint the peacock's plumage as camouflage by sleight of hand, "with the blue sky showing through the leaves in just sufficient quantity here and there to warrant the author-artists explaining that the wonderful blue hues of the peacock's neck are obliterative because they make it fade into the sky."
+In the 1970s a possible resolution to the apparent contradiction between natural selection and sexual selection was proposed. Amotz Zahavi argued that peacocks honestly signalled the handicap of having a large and costly train. However, the mechanism may be less straightforward than it seems – the cost could arise from depression of the immune system by the hormones that enhance feather development.
+The ornate train is believed to be the result of sexual selection by the females. Males use their ornate trains in a courtship display: they raise the feathers into a fan and quiver them. However, recent studies have failed to find a relation between the number of displayed eyespots and mating success. Marion Petrie tested whether or not these displays signaled a male's genetic quality by studying a feral population of peafowl in Whipsnade Wildlife Park in southern England. She showed that the number of eyespots in the train predicted a male's mating success, and this success could be manipulated by cutting the eyespots off some of the male's ornate feathers.Although the removal of eyespots makes males less successful in mating, eyespot removal substantially changes the appearance of male peafowls. It is likely that females mistake these males for sub-adults, or perceive that the males are physically damaged. Moreover, in a feral peafowl population, there is little variation in the number of eyespots in adult males. It is rare for adult males to lose a significant number of eyespots. Therefore, females' selection might depend on other sexual traits of males' trains. The quality of train is an honest signal of the condition of males; peahens do select males on the basis of their plumage. A recent study on a natural population of Indian peafowls in the Shivalik area of India has proposed a "high maintenance handicap" theory. It states that only the fittest males can afford the time and energy to maintain a long tail. Therefore, the long train is an indicator of good body condition, which results in greater mating success. While train length seems to correlate positively with MHC diversity in males, females do not appear to use train length to choose males. A study in Japan also suggests that peahens do not choose peacocks based on their ornamental plumage, including train length, number of eyespots and train symmetry. Another study in France brings up two possible explanations for the conflicting results that exist. The first explanation is that there might be a genetic variation of the trait of interest under different geographical areas due to a founder effect and/or a genetic drift. The second explanation suggests that "the cost of trait expression may vary with environmental conditions," so that a trait that is indicative of a particular quality may not work in another environment.Fisher's runaway model proposes positive feedback between female preference for elaborate trains and the elaborate train itself. This model assumes that the male train is a relatively recent evolutionary adaptation. However, a molecular phylogeny study on peacock-pheasants shows the opposite; the most recently evolved species is actually the least ornamented one. This finding suggests a chase-away sexual selection, in which "females evolve resistance to male ploys". A study in Japan goes on to conclude that the "peacocks' train is an obsolete signal for which female preference has already been lost or weakened".However, some disagreement has arisen in recent years concerning whether or not female peafowl do indeed select males with more ornamented trains. In contrast to Petrie's findings, a seven-year Japanese study of free-ranging peafowl came to the conclusion that female peafowl do not select mates solely on the basis of their trains. Mariko Takahashi found no evidence that peahens expressed any preference for peacocks with more elaborate trains (such as trains having more ocelli), a more symmetrical arrangement, or a greater length. Takahashi determined that the peacock's train was not the universal target of female mate choice, showed little variance across male populations, and, based on physiological data collected from this group of peafowl, do not correlate to male physical conditions. Adeline Loyau and her colleagues responded to Takahashi's study by voicing concern that alternative explanations for these results had been overlooked, and that these might be essential for the understanding of the complexity of mate choice. They concluded that female choice might indeed vary in different ecological conditions.
+A 2013 study that tracked the eye movements of peahens responding to male displays found that they looked in the direction of the upper train of feathers only when at long distances and that they looked only at the lower feathers when males displayed close to them. The rattling of the tail and the shaking of the wings helped in keeping the attention of females.
+
+
+=== Breeding ===
+
+Peacocks are polygamous, and the breeding season is spread out but appears to be dependent on the rains. Peafowls usually reach sexual maturity at the age of 2 to 3 years old. Several males may congregate at a lek site and these males are often closely related. Males at leks appear to maintain small territories next to each other and they allow females to visit them and make no attempt to guard harems. Females do not appear to favour specific males. The males display in courtship by raising the upper-tail coverts into an arched fan. The wings are held half open and drooped and it periodically vibrates the long feathers, producing a ruffling sound. The cock faces the hen initially and struts and prances around and sometimes turns around to display the tail. Males may also freeze over food to invite a female in a form of courtship feeding. Males may display even in the absence of females. When a male is displaying, females do not appear to show any interest and usually continue their foraging.The peak season in southern India is April to May, January to March in Sri Lanka and June in northern India. The nest is a shallow scrape in the ground lined with leaves, sticks and other debris. Nests are sometimes placed on buildings and, in earlier times, have been recorded using the disused nest platforms of the white-rumped vultures. The clutch consists of 4–8 fawn to buff white eggs which are incubated only by the female. The eggs take about 28 days to hatch. The chicks are nidifugous and follow the mother around after hatching. Downy young may sometimes climb on their mothers' back and the female may carry them in flight to a safe tree branch. An unusual instance of a male incubating a clutch of eggs has been reported.
+
+
+=== Feeding ===
+Peafowl are omnivorous and eat seeds, insects (including termites), worms, fruits, small mammals, frogs, and reptiles (such as lizards). They feed on small snakes but keep their distance from larger ones. In the Gir forest of Gujarat, a large percentage of their food is made up of the fallen berries of Zizyphus. They also feed on tree and flower buds, petals, grain, and grass and bamboo shoots. Around cultivated areas, peafowl feed on a wide range of crops such as groundnut, tomato, paddy, chili and even bananas. Around human habitations, they feed on a variety of food scraps and even human excreta. In the countryside, it is particularly partial to crops and garden plants.
+
+
+=== Mortality factors ===
+Large animals such as leopards, dholes, golden jackals, and tigers can ambush adult peafowls. However, only leopards regularly prey upon peafowls as adult peafowls are difficult to catch since they can usually escape ground predators by flying into trees.  They are also sometimes hunted by large birds of prey such as the changeable hawk-eagle and rock eagle-owl. Chicks are somewhat more prone to predation than adult birds. Adults living near human habitations are sometimes hunted by domestic dogs or by humans in some areas (southern Tamil Nadu) for folk remedies involving the use of "peacock oil".Foraging in groups provides some safety as there are more eyes to look out for predators. They also roost on high tree tops to avoid terrestrial predators, especially leopards.In captivity, birds have been known to live for 23 years but it is estimated that they live for only about 15 years in the wild.
+
+
+== Conservation and status ==
+
+Indian peafowl are widely distributed in the wild across South Asia and protected both culturally in many areas and by law in India. Conservative estimates of the population put them at more than 100,000. Illegal poaching for meat, however, continues and declines have been noted in parts of India. Peafowl breed readily in captivity and as free-ranging ornamental fowl. Zoos, parks, bird-fanciers and dealers across the world maintain breeding populations that do not need to be augmented by the capture of wild birds.
+Poaching of peacocks for their meat and feathers and accidental poisoning by feeding on pesticide treated seeds are known threats to wild birds. Methods to identify if feathers have been plucked or have been shed naturally have been developed, as Indian law allows only the collection of feathers that have been shed.In parts of India, the birds can be a nuisance to agriculture as they damage crops. Its adverse effects on crops, however, seem to be offset by the beneficial role it plays by consuming prodigious quantities of pests such as grasshoppers. They can also be a problem in gardens and homes where they damage plants, attack their reflections (thereby breaking glass and mirrors), perch and scratch cars or leave their droppings. Many cities where they have been introduced and gone feral have peafowl management programmes. These include educating citizens on how to prevent the birds from causing damage while treating the birds humanely.
+
+
+== In culture ==
+
+Prominent in many cultures, the peacock has been used in numerous iconic representations, including being designated the national bird of India in 1963. The peacock, known as mayura in Sanskrit, has enjoyed a fabled place in India since and is frequently depicted in temple art, mythology, poetry, folk music and traditions. A Sanskrit derivation of mayura is from the root mi for kill and said to mean "killer of snakes". It is also likely that the Sanskrit term is a borrowing from Proto-Dravidian *mayVr (whence the Tamil word for peacock மயில் (mayil)) or a regional Wanderwort. Many Hindu deities are associated with the bird, Krishna is often depicted with a feather in his headband, while worshippers of Shiva associate the bird as the steed of the God of war, Kartikeya (also known as Skanda or Murugan). A story in the Uttara Ramayana describes the head of the Devas, Indra, who unable to defeat Ravana, sheltered under the wing of peacock and later blessed it with a "thousand eyes" and fearlessness from serpents. Another story has Indra who after being cursed with a thousand ulcers was transformed into a peacock with a thousand eyes and this curse was removed by Vishnu.In Buddhist philosophy, the peacock represents wisdom. Peacock feathers are used in many rituals and ornamentation. Peacock motifs are widespread in Indian temple architecture, old coinage, textiles and continue to be used in many modern items of art and utility. A folk belief found in many parts of India is that the peacock does not copulate with the peahen but that she is impregnated by other means. The stories vary and include the idea that the peacock looks at its ugly feet and cries whereupon the tears are fed on by the peahen causing it to be orally impregnated while other variants incorporate sperm transfer from beak to beak. Similar ideas have also been ascribed to Indian crow species. In Greek mythology the origin of the peacock's plumage is explained in the tale of Hera and Argus. The main figure of the Yazidi religion Yezidism, Melek Taus, is most commonly depicted as a peacock. Peacock motifs are widely used even today such as in the logos of the US NBC and the PTV television networks and the Sri Lankan Airlines.
+
+These birds were often kept in menageries and as ornaments in large gardens and estates. In medieval times, knights in Europe took a "Vow of the Peacock" and decorated their helmets with its plumes. In several Robin Hood stories, the titular archer uses arrows fletched with peacock feathers. Feathers were buried with Viking warriors and the flesh of the bird was said to cure snake venom and many other maladies. Numerous uses in Ayurveda have been documented. Peafowl were said to keep an area free of snakes. In 1526, the legal issue as to whether peacocks were wild or domestic fowl was thought sufficiently important for Cardinal Wolsey to summon all the English judges to give their opinion, which was that they are domestic fowl.In Anglo-Indian usage of the 1850s, to peacock meant making visits to ladies and gentlemen in the morning. In the 1890s, the term "peacocking" in Australia referred to the practice of buying up the best pieces of land ("picking the eyes") so as to render the surrounding lands valueless. The English word "peacock" has come to be used to describe a man who is very proud or gives a lot of attention to his clothing.A golden peacock (in Yiddish, Di Goldene Pave) is considered by some as a symbol of Ashkenazi Jewish culture, and is the subject of several folktales and songs in Yiddish.
+Peacocks are frequently used in European heraldry. Heraldic peacocks are most often depicted as facing the viewer and with their tails displayed. In this pose, the peacock is referred to as being "in his pride". Peacock tails, in isolation from the rest of the bird, are rare in British heraldry, but see frequent use in German systems.

+The collared peccary (Dicotyles tajacu) is a species of artiodactyl (even-toed) mammal in the family Tayassuidae found in North, Central, and South America. It is the only member of the genus Dicotyles. They are commonly referred to as javelina, saíno, or báquiro, although these terms are also used to describe other species in the family. The species is also known as the musk hog. In Trinidad, it is colloquially known as quenk.
+
+
+== Taxonomy ==
+Although somewhat related to true Old World pigs, and frequently referred to as a pig, this species and the other peccaries are no longer classified in the pig family, Suidae. Although formerly classified in the genus Pecari, studies in 2020 placed them in the genus Dicotyles, based on an unequivocal type-species selection; these studies have been accepted by the American Society of Mammalogists. Currently, the IUCN still places them in the genus Pecari.
+
+
+== Description ==
+
+The collared peccary stands around 510–610 mm (20–24 in) tall at the shoulder and is about 1.0–1.5 m (3 ft 3 in – 4 ft 11 in) long. It weighs between 16 and 27 kg (35 and 60 lb). The dental formula is: 2/3,1/1,3/3,3/3. The collared peccary has small tusks that point toward the ground when the animal is upright. It has slender legs with a robust or stocky body. The tail is often hidden in the coarse fur of the peccary.
+
+
+== Range and habitat ==
+The collared peccary is widespread throughout much of the tropical and subtropical Americas, ranging from the Southwestern United States to northern Argentina. They were reintroduced to Uruguay in 2017, after 100 years of extirpation there. The only Caribbean island where it is native, however, is Trinidad. Until fairly recently, it was also present on the nearby island of Tobago, but is now exceedingly rare (if not extirpated) due to overhunting by humans. An adaptable species, it inhabits deserts, xeric shrublands, tropical and subtropical grasslands, savannas, shrublands, flooded grasslands and savannas, tropical and subtropical dry broadleaf forests, and several other habitats; it is also present in habitats shared by humans, merely requiring sufficient cover. Peccaries can be found in cities and agricultural land throughout their range, where they consume garden plants. Notable populations are known to exist in the suburbs of Phoenix and Tucson, Arizona.Due to the lack of fossil material or even specimens from archeological sites, it was assumed that javelinas only recently crossed into the US by way of Mexico. However, a fossil jaw of this species was discovered in Florida ("Collared peccary (Mammalia, Artiodactyla, Tayassuidae, Pecari) from the late Pleistocene of Florida", Richard C. Hulbert, Gary S. Morgan & Andreas Kerner), proving that at some point in the late Pleistocene the species had already inhabited part of the Southern US.
+
+
+== Diet ==
+Collared peccaries are often classified as herbivores. They normally feed on cactus, mesquite beans, fruits, berries, seeds, roots, tubers, bulbs, palm nuts, grasses, other green vegetation, fungi, and insects. However, they will also eat eggs, snakes, fish, frogs, lizards, dead birds, and rodents if the opportunity presents itself. Despite all this supplementary diet, the main dietary components of this species are agaves and prickly pears. In areas inhabited by humans, they also consume cultivated crops and ornamental plants, such as tulip bulbs.
+
+
+== Predators ==
+The main predators of the collared peccary are cougars (Puma concolor), Mexican wolves (Canis lupus baileyi), coyotes (Canis latrans), jaguars (Panthera onca), and bobcats (Lynx rufus).
+
+
+== Behavior ==
+Collared peccaries are diurnal creatures that live in groups of up to 50 individuals, averaging between six and nine animals. They sleep in burrows (often under bushes or larger systems of tree roots), but sometimes can be found in caves, abandoned mines, old desert tunnels, or among logs, felled trees and abandoned  timber.  However, collared peccaries are not completely diurnal. In central Arizona, they are often more active at night, and less so in the heat of the daytime.
+Although they usually ignore humans, they will react if they feel threatened. They defend themselves with their tusks. A collared peccary can release a strong musk or give a sharp bark if it is alarmed. Amazonian peoples (including the Shipibos) sometimes raise and tame juvenile collared peccaries, if they are encountered.  
+Peccary will also rub their scent onto rocks and tree stumps to mark their territory, and rub the scent on each other to help with identification.
+
+
+== The "giant peccary" ==
+The giant peccary (described as Pecari maximus) was a purported fourth species of peccary, first reported to have been seen in Brazil in 2000 by Dutch naturalist Marc van Roosmalen. In 2003 German natural history filmmaker Lothar Frenz filmed a group and gathered a skull which later served as the type (INPA4272). It had been known locally as caitetú-mundè, which Roosmalen et al. state the locals claimed was Tupí and meant "the collared peccary that is bigger and goes in pairs", as opposed to caitetú-de-bando, "the collared peccary that goes in herds". It was formally described in 2007, but the scientific evidence for its species status was quickly questioned, which also was one of the reasons for its initial evaluation as data deficient by IUCN in 2008. A review in 2011 moved the giant peccary into synonymy with the collared peccary (P. tajacu), which was followed by the IUCN the same year.The reported range of the giant peccary encompasses the south-central Amazon between the Madeira and the Tapajós Rivers and northern Bolivia. It is restricted to terra firme forest, which is forest that does not flood annually. Unlike other peccaries in its range, the giant peccary was reported to mainly occur in pairs or small family groups.According to its original description, the giant peccary is larger, longer-legged, and proportionally smaller-headed than the only other member of the genus, the collared peccary. Compared to most individuals of the sympatric populations of the collared peccary, the giant peccary also had thinner fur that is grizzled in brown and white, blacker legs, and a relatively faint collar. Five skins of the giant peccary had a total length of 120–137 cm (47–54 in), while local hunters have estimated a weight of 40–50 kg (88–110 lb). Based on a mtDNA study, the collared and the giant peccaries were estimated to have diverged 1.0–1.2 million years ago, but these results were later questioned due to the small sample size, low bootstrap support, and the absence of nDNA and cytogenetic results.In 2011, a review noted that the measurements provided in the initial description were within those generally recognized for the collared peccary, and the behaviors supposedly unique to the giant peccary are also known from the collared peccary. They also provided new genetic evidence showing that collared peccaries from South America form a monophyletic clade that includes the giant peccary (without it the clade is paraphyletic). The major genetic split within the collared peccary is between a clade comprising North and Central American specimens, and a clade comprising South American specimens (the presumed contact zone is in Colombia, which has both clades). Furthermore, extensive infraspecific variations (both individual and locality-based) are known in the morphology of the collared peccary.

+The great white pelican (Pelecanus onocrotalus) also known as the eastern white pelican, rosy pelican or white pelican is a bird in the pelican family. It breeds from southeastern Europe through Asia and  Africa, in swamps and shallow lakes.
+The great white pelican has been rated as a species of least concern on the IUCN Red List of Endangered Species (IUCN). It is listed under Appendix I of the Convention on the Conservation of Migratory Species of Wild Animals, Annexure I under the EU Birds Directive on the Conservation of Wild Birds, and Appendix II of the Berne Convention on the Conservation of European Wildlife and Natural Habitats. It is also listed within 108 Special Protection Areas in the European Union. It occurs within 43 Important Bird Areas (IBAs) in its European range. It is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) is applied.
+
+
+== Description ==
+
+The great white pelican is a huge bird—only the Dalmatian pelican is, on average, larger among pelicans. It measures 140 to 180 cm (55 to 71 in) in length with a 28.9 to 47.1 cm (11.4 to 18.5 in) enormous pink and yellow bill, and a dull pale-yellow gular pouch. The wingspan measures 226 to 360 cm (7 ft 5 in to 11 ft 10 in), the latter measurement being the highest among extant flying animals outside of the great albatross. The adult male measures about 175 cm (69 in) in length; it weighs from 9 to 15 kg (20 to 33 lb)  and larger races from the Palaearctic are usually around 11 kg (24 lb), with few exceeding 13 kg (29 lb). It has a bill measuring 34.7 to 47.1 cm (13.7 to 18.5 in). The female measures about 148 cm (58 in) in length, and is considerably less bulky, weighing 5.4 to 9 kg (12 to 20 lb), and has a bill that measures 28.9 to 40.0 cm (11.4 to 15.7 in) in length. In Lake Edward, Uganda, the average weight of 52 males was found to 11.45 kg (25.2 lb) and in 22 females it was 7.59 kg (16.7 lb). In South Africa, the average weight of males was 9.6 kg (21 lb) and of females was 6.9 kg (15 lb). Thus the sexual dimorphism is especially pronounced in this species (perhaps the greatest known in any extant pelican), as at times the male can average more than 30% more massive than the female. The great white pelican rivals the kori bustard, which has even more pronounced sexual dimorphism, as the heaviest flying bird to reside in Africa (both averaging perhaps slightly heavier than the cape vulture and the wattled crane). There are a small few slightly heavier flying birds in the Eurasian portions of the range. Among standard measurements, the wing chord is 60 to 73 cm (24 to 29 in), the tail 16 to 21 cm (6.3 to 8.3 in), and the tarsus 13 to 14.9 cm (5.1 to 5.9 in) long. Standard measurements from different areas indicate that pelicans from the Western Palaearctic are somewhat larger than those from Asia and Africa.
+The male has a downward bend in the neck and the female has a shorter, straighter beak. The plumage is predominantly white except on remiges, with a faint pink tinge on the neck and a yellowish base on the foreneck. The primary feathers are black, with white shafts at the bases, occasionally with paler tips and narrow fringes. The secondary feathers are also black, but with a whitish fringe. The upperwing coverts, underwing coverts, and tertials are white. The forehead is swollen and pinkish skin surrounds the bare, dark eyes having brown-red to dark brown irides. It has fleshy-yellow legs and pointed forehead-feathers where meeting the culmen. In breeding season, the male has pinkish skin while the female has orangey skin on its face. The bill is mostly bluish grey, with a red tip, reddish maxilla edges, and a cream-yellow to yolk-yellow gular pouch. The white plumage becomes tinged-pink with a yellow patch on the breast, and the body is tinged yellowish-rosy. It also has a short, shaggy crest on the nape. The white covert feathers contrast with the solid black primary and secondary feathers. The legs are yellow-flesh to pinkish orange. Both male and female are similar, but the female is smaller and has brighter orange facial skin in the breeding season.The juvenile has darker, brownish underparts that are palest at the rump, center of the belly, and uppertail coverts. The underwing coverts are mostly dull-white, but the greater coverts are dark and there is a dark brownish bar over the lesser coverts. The rear tertials upperwing coverts mostly have paler tips with a silvery-grey tinge on the greater secondary coverts and tertials. It has dark flight feathers, and brown-edged wings. The head, neck, and upperparts, including the upperwing coverts, are mostly brown—this is the darkest part of the neck. The facial skin and the bill, including its gular pouch, are greyish to dusky greyish. The forehead, rump, and abdomen are white, and its legs and feet are grey. Its blackish tail occasionally has a silvery-grey tinge. Its underparts and back are initially browner and darker than those of the Dalmatian pelican, and the underwing is strongly patterned, similar to the juvenile brown pelican.The great white pelican is distinguished from all other pelicans by its plumage. Its face is naked and the feathering on its forehead tapers to a fine point, whereas other species are completely feathered. In flight, the white underwing with black remiges of the adult are similar only to those of the American white pelican (P. erythrorhynchos), but the latter has white inner secondary feathers. It differs from the Dalmatian pelican in its pure white – rather than greyish-white – plumage, a bare pink facial patch around the eye, and pinkish legs. The spot-billed pelican (P. philippensis) of Asia is slightly smaller than the great white pelican, with greyish tinged white plumage, and a paler, duller-colored bill. Similarly, the pink-backed pelican (P. rufescens) is smaller, with brownish-grey plumage, a light pink to off-grey bill, and a pinkish wash on the back.The bird is mostly silent but has a variety of low-pitched lowing, grunting, and growling calls. The flight call is a deep, quiet croak., while at breeding colonies, it gives deep moooo calls.
+
+
+== Distribution and habitat ==
+
+The breeding range of the great white pelican extends to Ethiopia, Tanzania, Chad, northern Cameroons, and Nigeria in Africa, and has been observed or reported breeding in Zambia, Botswana, and South Africa. In the 1990s, 6,700 to 11,000 breeding pairs in 23 to 25 breeding sites, were found in the Palearctic region. A 1991 study noted about 3,070 to 4,300 pairs were present in the Soviet Union. Only two breeding colonies are located in the Mediterranean basin, one having 250 to 400 pairs in Turkey and the other having 50 to 100 pairs in northern Greece. The breeding colony at Lake Rukwa, Tanzania is the largest known breeding colony in Africa, followed by the Lake Shala, Ethiopia colony which is probably of crucial importance to the species in Africa.
+The African population of about 75,000 pairs of the great white pelican is resident. The ones breeding in the Palearctic region are migrants, although it is possible that the majority of the western Palearctic populations stop-over in Israel during their autumn migration. The migration routes are only partially known. Migratory populations are found from Eastern Europe to Kazakhstan during the breeding season. More than 50% of Eurasian great white pelicans breed in the Danube Delta in Romania. They also prefer staying in the Lakes near Burgas, Bulgaria and in Srebarna Lake in Bulgaria. The pelicans arrive in the Danube in late March or early April and depart after breeding from September to late November. Wintering locations for European pelicans are not exactly known but wintering birds may occur in northeastern Africa through Iraq to north India, with a particularly large number of breeders from Asia wintering around Pakistan and Sri Lanka. Northern populations migrate to China, India, Myanmar, with stragglers reaching Java and Bali in Indonesia. These are birds that are found mostly in lowlands, though in East Africa and Nepal may be found living at elevations of up to 1,372 m (4,501 ft).Overall, the great white pelican is one of the most widely distributed species. Although some areas still hold quite large colonies, it ranks behind the brown pelican and possibly the Australian pelican in overall abundance. Europe now holds an estimated 7,345–10,000 breeding pairs, with over 4,000 pairs that are known to nest in Russia. During migration, more than 75,000 have been observed in Israel and, in winter, over 45,000 may stay in Pakistan. In all its colonies combined, 75,000 pairs are estimated to nest in Africa. It is possibly extinct in Serbia and Montenegro, and regionally extinct in Hungary.Great white pelicans usually prefer shallow, (seasonally or tropical) warm fresh water. Well scattered groups of breeding pelicans occur through Eurasia from the eastern Mediterranean to Vietnam. In Eurasia, fresh or brackish waters may be inhabited and the pelicans may be found in lakes, deltas, lagoons and marshes, usually with dense reed beds nearby for nesting purposes. Additionally, sedentary populations are found year-round in Africa, south of the Sahara Desert although these are patchy. In Africa, great white pelicans occur mainly around freshwater and alkaline lakes and may also be found in coastal, estuarine areas. Beyond reed beds, African pelicans have nested on inselbergs and flat inshore islands off of Banc d'Arguin National Park.
+
+
+== Behavior ==
+
+The great white pelican is highly sociable and often forms large flocks. It is well adapted for aquatic life. The short strong legs and webbed feet propel it in water and aid a rather awkward takeoff from the water surface. In flight, it is an elegant soaring bird, with the head held close to and aligned with the body. Its flight consists of a few slow wingbeats followed by a glide. Once aloft, the long-winged pelicans are powerful fliers, however, and often travel in spectacular linear, circular, or V-formation groups.
+
+
+=== Feeding ===
+
+The great white pelican mainly eats fish. It leaves its roost to feed early in the morning and may fly over 100 km (62 mi) in search of food, as has been observed in Chad and in Mogode, Cameroon. It needs from 0.9 to 1.4 kg (2.0 to 3.1 lb) of fish every day, which corresponds to around 28,000,000 kg (62,000,000 lb) annual fish consumption at the largest colony of the great white pelican, on Tanzania's Lake Rukwa (with almost 75,000 birds). Fish targeted are usually fairly large ones, in the 500–600 g (1.1–1.3 lb) weight range, and are taken based on regional abundance. Common carp are preferred in Europe, mullets in China, and Arabian toothcarp in India. In Africa, often the commonest cichlids, including many species in the Haplochromis and Tilapia genera, seem to be preferred.The pelican's pouch serves simply as a scoop. As the pelican pushes its bill underwater, the lower bill bows out, creating a large pouch which fills with water and fish. As it lifts its head, the pouch contracts, forcing out the water but retaining the fish. A group of 6 to 8 great white pelicans gather in a horseshoe formation in water to feed together. They dip their bills in unison, creating a circle of open pouches, ready to trap every fish in the area. Most feeding is cooperative and done in groups, especially in shallow waters where fish schools can be corralled easily, though they may also forage alone as well.Great white pelicans are not restricted to fish, however, and are often opportunistic foragers. In some situations, they eat chicks of other birds, such as the well documented case off the southwest coast of South Africa. Here, breeding pelicans from the Dassen Island prey on chicks weighing up to 2 kg (4.4 lb) from the Cape gannet colony on Malgas Island. Similarly, in Walvis Bay, Namibia the eggs and chicks of Cape cormorants are fed regularly to young pelicans. The local pelican population is so reliant on the cormorants, that when the cormorant species experienced a population decline, the numbers of pelicans appeared to decline as well.They also rob other birds of their prey. During periods of starvation, they also eat seagulls and ducklings. The gulls are held under water and drowned before being eaten headfirst. A flock of captive great white pelicans in St James's Park, London is well known for occasionally eating local pigeons, despite being well-fed.
+
+
+=== Breeding ===
+
+The breeding season commences in April or May in temperate zones, is essentially all year around in Africa and runs February through April in India. Large numbers of these pelicans breed together in colonies.
+Nest locations vary: some populations make stick nests in trees but a majority, including all those that breed in Africa, nest exclusively in scrapes on the ground lined with grass, sticks, feathers and other material.The female can lay from 1 to 4 eggs in a clutch, with two being the average. Incubation takes 29 to 36 days. The chicks are naked when they hatch but quickly sprout blackish-brown down. The young are cared for by both parents.  The colony gathers in "pods" around 20 to 25 days after the eggs hatch. The young fledge at 65 to 75 days of age. Around 64% of young successful reach adulthood, attaining sexual maturity at 3 to 4 years of age.
+
+
+=== Predators ===
+While white pelicans are often protected from bird-eating raptors by virtue of their own great size, eagles, especially sympatric Haliaeetus species, may prey on their eggs, nestlings, and fledglings. Occasionally, pelicans and their young are attacked at their colonies by mammalian carnivores, such as jackals and lions. As is common in pelicans, the close approach of a large predaceous or unknown mammal, including a human, at a colony will lead the pelican to abandon its nest in self-preservation. Additionally, crocodiles, especially Nile crocodiles in Africa, readily kill and eat swimming pelicans.
+
+
+== Status and conservation ==
+Since 1998, the great white pelican has been rated as a species of least concern on the IUCN Red List of Endangered Species. This is because it has a large range – more than 20,000 km2 (7700 mi2) – and because its population is thought not to have declined by 30% over ten years or three generations, which is not a rapid enough decline to warrant a vulnerable rating. However, the state of its overall population is not known, and although it is widespread, it is not abundant anywhere. It is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. It is listed under the Appendix I of the Convention on the Conservation of Migratory Species of Wild Animals, Appendix II of the Berne Convention on the Conservation of European Wildlife and Natural Habitats and Annexure I of the EU Birds Directive on the Conservation of Wild Birds. It occurs within 43 Important Bird Areas in its European range, and is listed within 108 Special Protection Areas in the European Union. This species is often kept in captivity in zoos or in semi-wild colonies such as that in St. James's Park, London. The ancestors of this colony were originally given to Charles II by the Russian ambassador in 1664 which initiated the tradition of ambassadors donating the birds.Today, because of overfishing in certain areas, white pelicans are forced to fly long distances to find food. Great white pelicans are exploited for many reasons. Their pouch is used to make tobacco bags, their skin is turned into leather, the guano is used as fertiliser, and the fat of its young is converted into oils for traditional medicine in China and India. In Ethiopia, great white pelicans are shot for their meat. Human disturbance, loss of foraging habitat and breeding sites, as well as pollution are all contributing to the decline of the great white pelican. Declines have been particularly notable in the Palaearctic.

+Adanson's mud turtle (Pelusios adansonii) is a species of turtle in the family Pelomedusidae. The species is endemic to north-central Africa.
+
+
+== Taxonomy and etymology ==
+August Friedrich Schweigger first described the turtle in 1812, based on remnants found in Senegal by French botanist Michel Adanson, for whom Schweigger named the new species as Emys andansonii.
+
+
+== Geographic range ==
+P. adansonii is found in Benin, Cameroon, the Central African Republic, Chad, Ethiopia, Mali, Mauritania, Niger, Nigeria, Senegal, South Sudan, and Sudan. There are at least three distinct populations within the turtle's distribution.
+
+
+== Conservation status ==
+Although Adanson's mud turtle does not seem to be at risk of becoming an endangered species, destruction of its habitat (largely due to farming) and hunting by humans have both reduced its population. Hunting by humans persists despite local laws forbidding the activity in some of the countries in which the turtle is found.
+
+
+== Characteristics ==
+Adanson's mud turtle is a medium-sized turtle that lives in freshwater. The turtle's shell can grow up to 238 mm (9.4 in) (straight carapace length) and is known to be sharp and rigid, with dark brown spots and dashes. The ventral part of the shell (plastron) is yellow.
+
+
+== Diet ==
+Adanson's mud turtle is carnivorous. It eats mollusks, fish, and small amphibians.
+
+
+== Reserve ==
+A refuge for Adanson's mud turtle has taken place in the wetland area on the northwest side of Guiers Lake in northern Senegal and it covers about 750 acres (1.17 sq mi). It is the first refuge of its kind that is dedicated to the conservation of Adanson's mud turtle and its nesting and foraging habits. It was created with the help of the Turtle Survival Alliance (TSA Africa) and the Ministry of Environment and Nature Protection of Senegal.

+The koala or, inaccurately, koala bear (Phascolarctos cinereus), is an arboreal herbivorous marsupial native to Australia. It is the only extant representative of the family Phascolarctidae and its closest living relatives are the wombats. The koala is found in coastal areas of the mainland's eastern and southern regions, inhabiting Queensland, New South Wales, Victoria, and South Australia. It is easily recognisable by its stout, tailless body and large head with round, fluffy ears and large, spoon-shaped nose. The koala has a body length of 60–85 cm (24–33 in) and weighs 4–15 kg (9–33 lb). Fur colour ranges from silver grey to chocolate brown. Koalas from the northern populations are typically smaller and lighter in colour than their counterparts further south. These populations possibly are separate subspecies, but this is disputed.
+Koalas typically inhabit open Eucalyptus woodland, as the leaves of these trees make up most of their diet. Because this eucalypt diet has limited nutritional and caloric content, koalas are largely sedentary and sleep up to twenty hours a day. They are asocial animals, and bonding exists only between mothers and dependent offspring. Adult males communicate with loud bellows that intimidate rivals and attract mates. Males mark their presence with secretions from scent glands located on their chests. Being marsupials, koalas give birth to underdeveloped young that crawl into their mothers' pouches, where they stay for the first six to seven months of their lives. These young koalas, known as joeys, are fully weaned around a year old. Koalas have few natural predators and parasites, but are threatened by various pathogens, such as Chlamydiaceae bacteria and the koala retrovirus.
+Because of its distinctive appearance, the koala along with the kangaroos are recognised worldwide as symbols of Australia. They were hunted by Indigenous Australians and depicted in myths and cave art for millennia. The first recorded encounter between a European and a koala was in 1798, and an image of the animal was published in 1810 by naturalist George Perry. Botanist Robert Brown wrote the first detailed scientific description of the koala in 1814, although his work remained unpublished for 180 years. Popular artist John Gould illustrated and described the koala, introducing the species to the general British public. Further details about the animal's biology were revealed in the 19th century by several English scientists. Koalas are listed as a vulnerable species by the International Union for Conservation of Nature. Among the many threats to their existence are habitat destruction caused by agriculture, urbanisation, droughts, and associated bushfires, some related to climate change.  In February of 2022, the koala was officially listed as endangered in the Australian Capital Territory, New South Wales, and Queensland.
+
+
+== Etymology ==
+The word koala comes from the Dharug gula, meaning no water.  Although the vowel 'u' was originally written in the English orthography as "oo" (in spellings such as coola or koolah — two syllables), later became "oa" and is now pronounced in three syllables, possibly in error.Adopted by white settlers, "koala" became one of several hundred Aboriginal loan words in Australian English, where it was also commonly referred to as "native bear", later "koala bear", for its supposed resemblance to a bear. It is also one of several Aboriginal words that made it into International English, alongside e.g. "didgeridoo" and "kangaroo." The generic name, Phascolarctos, is derived from the Greek words phaskolos "pouch" and arktos "bear". The specific name, cinereus, is Latin for "ash coloured".
+
+
+== Taxonomy and evolution ==
+The koala was given its generic name Phascolarctos in 1816 by French zoologist Henri Marie Ducrotay de Blainville, who would not give it a specific name until further review. In 1819, German zoologist Georg August Goldfuss gave it the binomial Lipurus cinereus. Because Phascolarctos was published first, according to the International Code of Zoological Nomenclature, it has priority as the official name of the genus.: 58–59  French naturalist Anselme Gaëtan Desmarest proposed the name Phascolarctos fuscus in 1820, suggesting that the brown-coloured versions were a different species than the grey ones. Other names suggested by European authors included Marodactylus cinereus by Goldfuss in 1820, P. flindersii by René Primevère Lesson in 1827, and P. koala by John Edward Gray in 1827.: 45 The koala is classified with wombats (family Vombatidae) and several extinct families (including marsupial tapirs, marsupial lions and giant wombats) in the suborder Vombatiformes within the order Diprotodontia. The Vombatiformes are a sister group to a clade that includes macropods (kangaroos and wallabies) and possums. The ancestors of vombatiforms were likely arboreal, and the koala's lineage was possibly the first to branch off around 40 million years ago during the Eocene.
+
+The modern koala is the only extant member of Phascolarctidae, a family that once included several genera and species. During the Oligocene and Miocene, koalas lived in rainforests and had less specialised diets. Some species, such as the Riversleigh rainforest koala (Nimiokoala greystanesi) and some species of Perikoala, were around the same size as the modern koala, while others, such as species of Litokoala, were one-half to two-thirds its size. Like the modern species, prehistoric koalas had well developed ear structures which suggests that long-distance vocalising and sedentism developed early. During the Miocene, the Australian continent began drying out, leading to the decline of rainforests and the spread of open Eucalyptus woodlands. The genus Phascolarctos split from Litokoala in the late Miocene and had several adaptations that allowed it to live on a specialised eucalyptus diet: a shifting of the palate towards the front of the skull; larger molars and premolars; smaller pterygoid fossa; and a larger gap between the molar and the incisor teeth.: 226 P. cinereus may have emerged as a dwarf form of the giant koala (P. stirtoni). The reduction in the size of large mammals has been seen as a common phenomenon worldwide during the late Pleistocene, and several Australian mammals, such as the agile wallaby, are traditionally believed to have resulted from this dwarfing. A 2008 study questions this hypothesis, noting that P. cinereus and P. stirtoni were sympatric during the middle to late Pleistocene, and possibly as early as the Pliocene. The fossil record of the modern koala extends back at least to the middle Pleistocene.
+
+
+=== Genetics and variations ===
+Three subspecies are recognised: the Queensland koala (Phascolarctos cinereus adustus, Thomas 1923), the New South Wales koala (Phascolarctos cinereus cinereus, Goldfuss 1817), and the Victorian koala (Phascolarctos cinereus victor, Troughton 1935). These forms are distinguished by pelage colour and thickness, body size, and skull shape. The Queensland koala is the smallest of the three, with shorter, silver fur and a shorter skull. The Victorian koala is the largest, with shaggier, brown fur and a wider skull.: 7  The boundaries of these variations are based on state borders, and their status as subspecies is disputed. A 1999 genetic study suggests that the variations represent differentiated populations with limited gene flow between them and that the three subspecies comprise a single evolutionarily significant unit. Other studies have found that koala populations have high levels of inbreeding and low genetic variation. Such low genetic diversity may have been a characteristic of koala populations since the late Pleistocene. Rivers and roads have been shown to limit gene flow and contribute to the genetic differentiation of southeast Queensland populations. In April 2013, scientists from the Australian Museum and Queensland University of Technology announced they had fully sequenced the koala genome.
+
+
+== Characteristics and adaptations ==
+
+The koala is a stocky animal with a large head and vestigial or non-existent tail.: 1  It has a body length of 60–85 cm (24–33 in) and a weight of 4–15 kg (9–33 lb), making it among the largest arboreal marsupials. Koalas from Victoria are twice as heavy as those from Queensland.: 7  The species is sexually dimorphic, with males 50% larger than females. Males are further distinguished from females by their more curved noses and the presence of chest glands, which are visible as hairless patches.: 55  As in most marsupials, the male koala has a bifurcated penis, and the female has two lateral vaginas and two separate uteri.: 3   The male's penile sheath contains naturally occurring bacteria that play an important role in fertilisation. The female's pouch opening is tightened by a sphincter that keeps the young from falling out.The pelage of the koala is thicker and longer on the back, and shorter on the belly. The ears have thick fur on both the inside and outside. The back fur colour varies from light grey to chocolate brown.: 1–2   The belly fur is whitish; on the rump it is dappled whitish, and darker at the back. The koala has the most effective insulating back fur of any marsupial and is highly resilient to wind and rain, while the belly fur can reflect solar radiation. The koala's curved, sharp claws are well adapted for climbing trees. The large forepaws have two opposable digits (the first and second, which are opposable to the other three) that allow them to grasp small branches. On the hind paws, the second and third digits are fused, a typical condition for members of the Diprotodontia, and the attached claws (which are still separate) are used for grooming.: 5  As in humans and other primates, koalas have friction ridges on their paws. The animal has a sturdy skeleton and a short, muscular upper body with proportionately long upper limbs that contribute to its climbing and grasping abilities. Additional climbing strength is achieved with thigh muscles that attach to the shinbone lower than other animals.: 183  The koala has a cartilaginous pad at the end of the spine that may make it more comfortable when it perches in the fork of a tree.
+
+The koala has one of the smallest brains in proportion to body weight of any mammal,: 81  being 60% smaller than that of a typical diprotodont, weighing only 19.2 g (0.68 oz) on average. The brain's surface is fairly smooth, typical for a "primitive" animal.: 52  It occupies only 61% of the cranial cavity: 81  and is pressed against the inside surface by cerebrospinal fluid. The function of this relatively large amount of fluid is not known, although one possibility is that it acts as a shock absorber, cushioning the brain if the animal falls from a tree.: 52  The koala's small brain size may be an adaptation to the energy restrictions imposed by its diet, which is insufficient to sustain a larger brain.: 81  Because of its small brain, the koala has a limited ability to perform complex, unfamiliar behaviours. For example, when presented with plucked leaves on a flat surface, the animal cannot adapt to the change in its normal feeding routine and will not eat the leaves.: 234  The koala's olfactory senses are normal, and it is known to sniff the oils of individual branchlets to assess their edibility.: 81  Its nose is fairly large and covered in leathery skin. Its round ears provide it with good hearing, and it has a well-developed middle ear. A koala's vision is not well developed, and its relatively small eyes are unusual among marsupials in that the pupils have vertical slits. Koalas make use of a novel vocal organ to produce low-pitched sounds (see social spacing, below). Unlike typical mammalian vocal cords, which are folds in the larynx, these organs are placed in the velum (soft palate) and are called velar vocal cords.
+
+The koala has several adaptations for its eucalypt diet, which is of low nutritive value, high toxicity, and high in dietary fibre.: 76  The animal's dentition consists of the incisors and cheek teeth (a single premolar and four molars on each jaw), which are separated by a large gap (a characteristic feature of herbivorous mammals). The incisors are used for grasping leaves, which are then passed to the premolars to be snipped at the petiole before being passed to the highly cusped molars, where they are shredded into small pieces.: 46  Koalas may also store food in their cheek pouches before it is ready to be chewed. The partially worn molars of middle-aged koalas are optimal for breaking the leaves into small particles, resulting in more efficient stomach digestion and nutrient absorption in the small intestine,: 231  which digests the eucalyptus leaves to provide most of the animal's energy.: 47  A koala sometimes regurgitates the food into the mouth to be chewed a second time.Unlike kangaroos and eucalyptus-eating possums, koalas are hindgut fermenters, and their digestive retention can last for up to 100 hours in the wild or up to 200 hours in captivity.: 48  This is made possible by the extraordinary length of their caecum—200 cm (80 in) long and 10 cm (4 in) in diameter—the largest proportionally of any animal.: 188  Koalas can select which food particles to retain for longer fermentation and which to pass through. Large particles typically pass through more quickly, as they would take more time to digest.: 48  While the hindgut is proportionally larger in the koala than in other herbivores, only 10% of the animal's energy is obtained from fermentation. Since the koala gains a low amount of energy from its diet, its metabolic rate is half that of a typical mammal,: 76  although this can vary between seasons and sexes.: 49  They can digest the toxins present in eucalyptus leaves due to their production of cytochrome P450, which breaks down these poisons in the liver. The koala conserves water by passing relatively dry faecal pellets high in undigested fibre, and by storing water in the caecum.: 231 
+
+
+== Distribution and habitat ==
+The koala's geographic range covers roughly 1,000,000 km2 (390,000 sq mi), and 30 ecoregions. It extends throughout eastern and southeastern Australia, encompassing northeastern, central and southeastern Queensland, eastern New South Wales, Victoria, and southeastern South Australia. The koala was reintroduced near Adelaide and on several islands, including Kangaroo Island and French Island. The population on Magnetic Island represents the northern limit of its range. Fossil evidence shows that the koala's range stretched as far west as southwestern Western Australia during the late Pleistocene. Koalas were introduced to Western Australia at Yanchep. They were likely driven to extinction in these areas by environmental changes and hunting by Indigenous Australians.: 12–13  In South Australia, koalas were only known to exist in recent times in the lower South East,: 32  with a remnant population in the Bangham Forest between Bordertown and Naracoorte, until introduced to the Mount Lofty Ranges in the 20th-century. Doubts have been cast on Eyre's identification as koala pelt a girdle being worn by an Aboriginal man, the only evidence of their existence elsewhere in the State.
+Koalas can be found in habitats ranging from relatively open forests to woodlands, and in climates ranging from tropical to cool temperate. In semi-arid climates, they prefer riparian habitats, where nearby streams and creeks provide refuge during times of drought and extreme heat.
+
+
+== Ecology and behaviour ==
+
+
+=== Foraging and activities ===
+
+Koalas are herbivorous, and while most of their diet consists of eucalypt leaves, they can be found in trees of other genera, such as Acacia, Allocasuarina, Callitris, Leptospermum, and Melaleuca.: 73  Though the foliage of over 600 species of Eucalyptus is available, the koala shows a strong preference for around 30. They tend to choose species that have a high protein content and low proportions of fibre and lignin.: 231  The most favoured species are Eucalyptus microcorys, E. tereticornis, and E. camaldulensis, which, on average, make up more than 20% of their diet. They will also consume other species in the genus such as E. ovata, E. punctata, and E. viminalis. Despite its reputation as a fussy eater, the koala is more generalist than some other marsupial species, such as the greater glider. Since eucalypt leaves have a high water content, the koala does not need to drink often;: 74  its daily water turnover rate ranges from 71 to 91 ml/kg of body weight. Although females can meet their water requirements by eating leaves, larger males require additional water found on the ground or in tree hollows.: 231  When feeding, a koala holds onto a branch with hind paws and one forepaw while the other forepaw grasps foliage. Small koalas can move close to the end of a branch, but larger ones stay near the thicker bases.: 96  Koalas consume up to 400 grams (14 oz) of leaves a day, spread over four to six feeding sessions.: 187  Despite their adaptations to a low-energy lifestyle, they have meagre fat reserves and need to feed often.: 189 Because they get so little energy from their diet, koalas must limit their energy use and sleep or rest 20 hours a day.: 93  They are predominantly active at night and spend most of their waking hours feeding. They typically eat and sleep in the same tree, possibly for as long as a day.: 39  On very hot days, a koala may climb down to the coolest part of the tree which is cooler than the surrounding air. The koala hugs the tree to lose heat without panting. On warm days, a koala may rest with its back against a branch or lie on its stomach or back with its limbs dangling.: 93–94  During cold, wet periods, it curls itself into a tight ball to conserve energy.: 39  On windy days, a koala finds a lower, thicker branch on which to rest. While it spends most of the time in the tree, the animal descends to the ground to move to another tree.: 94  The koala usually grooms itself with its hind paws, but sometimes uses its forepaws or mouth.: 97–98 
+
+
+=== Social spacing ===
+
+Koalas are asocial animals and spend just 15 minutes a day on social behaviours. In Victoria, home ranges are small and have extensive overlap, while in central Queensland they are larger and overlap less.: 98  Koala society appears to consist of "residents" and "transients", the former being mostly adult females and the latter males. Resident males appear to be territorial and dominate others with their larger body size. Alpha males tend to establish their territories close to breeding females, while younger males are subordinate until they mature and reach full size.: 191  Adult males occasionally venture outside their home ranges; when they do so, dominant ones retain their status.: 99  When a male enters a new tree, he marks it by rubbing his chest gland against the trunk or a branch; males have occasionally been observed to dribble urine on the trunk. This scent-marking behaviour probably serves as communication, and individuals are known to sniff the base of a tree before climbing.: 54–56  Scent marking is common during aggressive encounters. Chest gland secretions are complex chemical mixtures—about 40 compounds were identified in one analysis—that vary in composition and concentration with the season and the age of the individual.
+
+Adult males communicate with loud bellows—low pitched sounds that consist of snore-like inhalations and resonant exhalations that sound like growls. These sounds are thought to be generated by unique vocal organs found in koalas. Because of their low frequency, these bellows can travel far through air and vegetation.: 56  Koalas may bellow at any time of the year, particularly during the breeding season, when it serves to attract females and possibly intimidate other males. They also bellow to advertise their presence to their neighbours when they enter a new tree.: 57  These sounds signal the male's actual body size, as well as exaggerate it; females pay more attention to bellows that originate from larger males. Female koalas bellow, though more softly, in addition to making snarls, wails, and screams. These calls are produced when in distress and when making defensive threats. Young koalas squeak when in distress. As they get older, the squeak develops into a "squawk" produced both when in distress and to show aggression. When another individual climbs over it, a koala makes a low grunt with its mouth closed. Koalas make numerous facial expressions. When snarling, wailing, or squawking, the animal curls the upper lip and points its ears forward. During screams, the lips retract and the ears are drawn back. Females bring their lips forward and raise their ears when agitated.: 102–05 Agonistic behaviour typically consists of squabbles between individuals climbing over or passing each other. This occasionally involves biting. Males that are strangers may wrestle, chase, and bite each other.: 102  In extreme situations, a male may try to displace a smaller rival from a tree. This involves the larger aggressor climbing up and attempting to corner the victim, which tries either to rush past him and climb down or to move to the end of a branch. The aggressor attacks by grasping the target by the shoulders and repeatedly biting him. Once the weaker individual is driven away, the victor bellows and marks the tree.: 101–02  Pregnant and lactating females are particularly aggressive and attack individuals that come too close. In general, however, koalas tend to avoid energy-wasting aggressive behaviour.: 191 
+
+
+=== Reproduction and development ===
+
+Koalas are seasonal breeders, and births take place from the middle of spring through the summer to early autumn, from October to May. Females in oestrus tend to hold their heads further back than usual and commonly display tremors and spasms. However, males do not appear to recognise these signs and have been observed to mount non-oestrous females. Because of his much larger size, a male can usually force himself on a female, mounting her from behind, and in extreme cases, the male may pull the female out of the tree. A female may scream and vigorously fight off her suitors but will submit to one that is dominant or is more familiar. The bellows and screams that accompany matings can attract other males to the scene, obliging the incumbent to delay mating and fight off the intruders. These fights may allow the female to assess which is dominant.: 58–60  Older males usually have accumulated scratches, scars, and cuts on the exposed parts of their noses and their eyelids.: 192 The koala's gestation period lasts 33–35 days, and a female gives birth to a single joey (although twins occur on occasion). As with all marsupials, the young are born while at the embryonic stage, weighing only 0.5 g (0.02 oz). However, they have relatively well-developed lips, forelimbs, and shoulders, as well as functioning respiratory, digestive, and urinary systems. The joey crawls into its mother's pouch to continue the rest of its development.: 61  Unlike most other marsupials, the koala does not clean her pouch.: 181 A female koala has two teats; the joey attaches itself to one of them and suckles for the rest of its pouch life.: 61  The koala has one of the lowest milk energy production rates, relative to body size, of any mammal. The female makes up for this by lactating for as long as 12 months.: 62  At seven weeks of age, the joey's head grows longer and becomes proportionally large, pigmentation begins to develop, and its sex can be determined (the scrotum appears in males and the pouch begins to develop in females). At 13 weeks, the joey weighs around 50 g (1.8 oz) and its head has doubled in size. The eyes begin to open and fine fur grows on the forehead, nape, shoulders, and arms. At 26 weeks, the fully furred animal resembles an adult and begins to poke its head out of the pouch.: 63 
+
+As the young koala approaches six months, the mother begins to prepare it for its eucalyptus diet by predigesting the leaves, producing a faecal pap that the joey eats from her cloaca. The pap is quite different in composition from regular faeces, resembling instead the contents of the caecum, which has a high concentration of bacteria. Eaten for about a month, the pap provides a supplementary source of protein at a transition time from a milk to a leaf diet.: 235  The joey fully emerges from the pouch for the first time at six or seven months of age, when it weighs 300–500 g (11–18 oz). It explores its new surroundings cautiously, clinging to its mother for support. By nine months, it weighs over 1 kg (2.2 lb) and develops its adult fur colour. Having permanently left the pouch, it rides on its mother's back for transportation, learning to climb by grasping branches.: 65–66  Gradually, it spends more time away from its mother, who becomes pregnant again after 12 months when the young is now around 2.5 kg (5.5 lb). Her bond with her previous offspring is permanently severed and she no longer allows it to suckle, but it will continue to live near her for the next 6–12 months.: 66–67 Females become sexually mature at about three years of age and can then become pregnant; in comparison, males reach sexual maturity when they are about four years old, although they can produce sperm as early as two years.: 68  While the chest glands can be functional as early as 18 months of age, males do not begin scent-marking behaviours until they reach sexual maturity. Because the offspring have a long dependent period, female koalas usually breed in alternate years. Favourable environmental factors, such as a plentiful supply of high-quality food trees, allow them to reproduce every year.: 236 
+
+
+=== Health and mortality ===
+Koalas may live from 13 to 18 years in the wild. While female koalas usually live this long, males may die sooner because of their more hazardous lives.: 69  Koalas usually survive falls from trees and immediately climb back up, but injuries and deaths from falls do occur, particularly in inexperienced young and fighting males.: 72–73  Around six years of age, the koala's chewing teeth begin to wear down and their chewing efficiency decreases. Eventually, the cusps disappear completely and the animal will die of starvation. Koalas have few predators; dingos and large pythons may prey on them; birds of prey (such as powerful owls and wedge-tailed eagles) are threats to young. Koalas are generally not subject to external parasites, other than ticks in coastal areas. Koalas may also suffer mange from the mite Sarcoptes scabiei, and skin ulcers from the bacterium Mycobacterium ulcerans, but neither is common. Internal parasites are few and largely harmless.: 71–73  These include the tapeworm Bertiella obesa, commonly found in the intestine, and the nematodes Marsupostrongylus longilarvatus and Durikainema phascolarcti, which are infrequently found in the lungs. In a three-year study of almost 600 koalas admitted to the Australian Zoo Wildlife Hospital in Queensland, 73.8% of the animals were infected with at least one species of the parasitic protozoal genus Trypanosoma, the most common of which was T. irwini.Koalas can be subject to pathogens such as Chlamydiaceae bacteria,: 74–75  which can cause keratoconjunctivitis, urinary tract infection, and reproductive tract infection.: 229–30  Such infections are widespread on the mainland, but absent in some island populations.: 114  The koala retrovirus (KoRV) may cause koala immune deficiency syndrome (KIDS) which is similar to AIDS in humans. Prevalence of KoRV in koala populations suggests a trend spreading from the north to the south of Australia. Northern populations are completely infected, while some southern populations (including Kangaroo Island) are free.The animals are vulnerable to bushfires due to their slow movements and the flammability of eucalypt trees.: 26  The koala instinctively seeks refuge in the higher branches, where it is vulnerable to intense heat and flames. Bushfires also fragment the animal's habitat, which restricts their movement and leads to population decline and loss of genetic diversity.: 209–11  Dehydration and overheating can also prove fatal.: 80  Consequently, the koala is vulnerable to the effects of climate change. Models of climate change in Australia predict warmer and drier climates, suggesting that the koala's range will shrink in the east and south to more mesic habitats.

+=== History ===
+
+The first written reference to the koala was recorded by John Price, servant of John Hunter, the Governor of New South Wales. Price encountered the "cullawine" on 26 January 1798, during an expedition to the Blue Mountains, although his account was not published until nearly a century later in Historical Records of Australia.: 8  In 1802, French-born explorer Francis Louis Barrallier encountered the animal when his two Aboriginal guides, returning from a hunt, brought back two koala feet they were intending to eat. Barrallier preserved the appendages and sent them and his notes to Hunter's successor, Philip Gidley King, who forwarded them to Joseph Banks. Similar to Price, Barrallier's notes were not published until 1897.: 9–10  Reports of the first capture of a live "koolah" appeared in The Sydney Gazette in August 1803. Within a few weeks Flinders' astronomer, James Inman, purchased a specimen pair for live shipment to Joseph Banks in England. They were described as 'somewhat larger than the Waumbut (Wombat)'. These encounters helped provide the impetus for King to commission the artist John Lewin to paint watercolours of the animal. Lewin painted three pictures, one of which was subsequently made into a print that was reproduced in Georges Cuvier's Le Règne Animal (The Animal Kingdom) (first published in 1817) and several European works on natural history.: 12–13, 45 Botanist Robert Brown was the first to write a detailed scientific description of the koala in 1803, based on a female specimen captured near what is now Mount Kembla in the Illawarra region of New South Wales. Austrian botanical illustrator Ferdinand Bauer drew the animal's skull, throat, feet, and paws. Brown's work remained unpublished and largely unnoticed, however, as his field books and notes remained in his possession until his death, when they were bequeathed to the British Museum (Natural History) in London. They were not identified until 1994, while Bauer's koala watercolours were not published until 1989.: 16–28  British surgeon Everard Home included details of the koala based on eyewitness accounts of William Paterson, who had befriended Brown and Bauer during their stay in New South Wales.: 33–36  Home, who in 1808 published his report in the journal Philosophical Transactions of the Royal Society, gave the animal the scientific name Didelphis coola.: 36 
+The first published image of the koala appeared in George Perry's (1810) natural history work Arcana.: 37  Perry called it the "New Holland Sloth" on account of its perceived similarities to the Central and South American tree-living mammals of the genus Bradypus. His disdain for the koala, evident in his description of the animal, was typical of the prevailing early 19th-century British attitude about the primitiveness and oddity of Australian fauna:: 40  ...  the eye is placed like that of the Sloth, very close to the mouth and nose, which gives it a clumsy awkward appearance, and void of elegance in the combination ... they have little either in their character or appearance to interest the Naturalist or Philosopher. As Nature however provides nothing in vain, we may suppose that even these torpid, senseless creatures are wisely intended to fill up one of the great links of the chain of animated nature ...
+
+Naturalist and popular artist John Gould illustrated and described the koala in his three-volume work The Mammals of Australia (1845–1863) and introduced the species, as well as other members of Australia's little-known faunal community, to the general British public.: 87–93  Comparative anatomist Richard Owen, in a series of publications on the physiology and anatomy of Australian mammals, presented a paper on the anatomy of the koala to the Zoological Society of London. In this widely cited publication, he provided the first careful description of its internal anatomy, and noted its general structural similarity to the wombat.: 94–96  English naturalist George Robert Waterhouse, curator of the Zoological Society of London, was the first to correctly classify the koala as a marsupial in the 1840s. He identified similarities between it and its fossil relatives Diprotodon and Nototherium, which had been discovered just a few years before.: 46–48  Similarly, Gerard Krefft, curator of the Australian Museum in Sydney, noted evolutionary mechanisms at work when comparing the koala to its ancestral relatives in his 1871 The Mammals of Australia.: 103–105 The first living koala in Britain arrived in 1881, purchased by the Zoological Society of London. As related by prosecutor to the society, William Alexander Forbes, the animal suffered an accidental demise when the heavy lid of a washstand fell on it and it was unable to free itself. Forbes used the opportunity to dissect the fresh female specimen, thus was able to provide explicit anatomical details on the female reproductive system, the brain, and the liver—parts not previously described by Owen, who had access only to preserved specimens.: 105–06  Scottish embryologist William Caldwell—well known in scientific circles for determining the reproductive mechanism of the platypus—described the uterine development of the koala in 1884, and used the new information to convincingly place the koala and the monotremes into an evolutionary time frame.: 111

+
+=== Cultural significance ===
+
+The koala is well known worldwide and is a major draw for Australian zoos and wildlife parks.  It has been featured in advertisements, games, cartoons, and as soft toys.: ix  It benefited the national tourism industry by over an estimated billion Australian dollars in 1998, a figure that has since grown.: 201  In 1997, half of the visitors to Australia, especially those from Korea, Japan, and Taiwan, sought out zoos and wildlife parks; about 75% of European and Japanese tourists placed the koala at the top of their list of animals to see.: 216  According to biologist Stephen Jackson: "If you were to take a straw poll of the animal most closely associated with Australia, it's a fair bet that the koala would come out marginally in front of the kangaroo".: ix  Factors that contribute to the koala's enduring popularity include its childlike body proportions and teddy bear-like face.: 3 The koala is featured in the Dreamtime stories and mythology of Indigenous Australians. The Tharawal people believed that the animal helped row the boat that brought them to the continent.: 21  Another myth tells of how a tribe killed a koala and used its long intestines to create a bridge for people from other parts of the world. This narrative highlights the koala's status as a game animal and the length of its intestines.: 17  Several stories tell of how the koala lost its tail. In one, a kangaroo cuts it off to punish the koala for being lazy and greedy.: 28  Tribes in both Queensland and Victoria regarded the koala as a wise animal and sought its advice. Bidjara-speaking people credited the koala for turning barren lands into lush forests.: 41–43  The animal is also depicted in rock carvings, though not as much as some other species.: 45–46 Early European settlers in Australia considered the koala to be a prowling sloth-like animal with a "fierce and menacing look".: 143  At the beginning of the 20th century, the koala's reputation took a more positive turn, largely due to its growing popularity and depiction in several widely circulated children's stories.: 162  It is featured in Ethel Pedley's 1899 book Dot and the Kangaroo, in which it is portrayed as the "funny native bear".: 144  Artist Norman Lindsay depicted a more anthropomorphic koala in The Bulletin cartoons, starting in 1904. This character also appeared as Bunyip Bluegum in Lindsay's 1918 book The Magic Pudding.: 147  Perhaps the most famous fictional koala is Blinky Bill. Created by Dorothy Wall in 1933, the character appeared in several books and has been the subject of films, TV series, merchandise, and a 1986 environmental song by John Williamson.: 149–52  The first Australian stamp featuring a koala was issued by the Commonwealth in 1930.: 164  A television ad campaign for Australia's national airline Qantas, starting in 1967 and running for several decades, featured a live koala (voiced by Howard Morris), who complained that too many tourists were coming to Australia and concluded "I hate Qantas". The series has been ranked among the greatest commercials of all time.The song "Ode to a Koala Bear" appears on the B-side of the 1983 Paul McCartney/Michael Jackson duet single Say Say Say.: 151  A koala is the main character in Hanna-Barbera's The Kwicky Koala Show and Nippon Animation's Noozles, both of which were animated cartoons of the early 1980s. Food products shaped like the koala include the Caramello Koala chocolate bar and the bite-sized cookie snack Koala's March. Dadswells Bridge in Victoria features a tourist complex shaped like a giant koala: 155–58  and the Queensland Reds rugby team has a koala as its mascot.: 160  The Platinum Koala and Australian Silver Koala coins feature the animal on the reverse and Elizabeth II on the obverse.
+
+The drop bear is an imaginary creature in contemporary Australian folklore featuring a predatory, carnivorous version of the koala. This hoax animal is commonly spoken about in tall tales designed to scare tourists. While koalas are typically docile herbivores, drop bears are described as unusually large and vicious marsupials that inhabit treetops and attack unsuspecting people (or other prey) that walk beneath them by dropping onto their heads from above.
+
+
+=== Koala diplomacy ===
+Prince Henry, Duke of Gloucester, visited the Koala Park Sanctuary in Sydney in 1934 and was "intensely interested in the bears". His photograph, with Noel Burnet, the founder of the park, and a koala, appeared in The Sydney Morning Herald. After World War II, when tourism to Australia increased and the animals were exported to zoos overseas, the koala's international popularity rose. Several political leaders and members of royal families had their pictures taken with koalas, including Queen Elizabeth II, Prince Harry, Crown Prince Naruhito, Crown Princess Masako, Pope John Paul II, US President Bill Clinton, Soviet premier Mikhail Gorbachev and South African President Nelson Mandela: 156 At the 2014 G20 Brisbane summit, hosted by Prime Minister Tony Abbott, many world leaders including Russian President Vladimir Putin and US President Barack Obama were photographed holding koalas. The event gave rise to the term "koala diplomacy", which then became the Oxford Word of the Month for December 2016. 
+The term also includes the loan of koalas by the Australian government to overseas zoos in countries such as Singapore and Japan, as a form of "soft power diplomacy", like the "panda diplomacy" practised by China.
+
+
+== Conservation issues ==
+
+The koala was originally classified as Least Concern on the Red List, and reassessed as Vulnerable in 2014. In the Australian Capital Territory, New South Wales and Queensland, the species was listed under the EPBC Act in February 2022 as endangered by extinction. The described population was determined in 2012 to be "a species for the purposes of the EPBC Act 1999" in Federal legislation.Australian policymakers had declined a 2009 proposal to include the koala in the Environment Protection and Biodiversity Conservation Act 1999. In 2012, the Australian government listed koala populations in Queensland and New South Wales as Vulnerable, because of a 40% population decline in the former and a 33% decline in the latter. A 2017 WWF report found a 53% decline per generation in Queensland, and a 26% decline in New South Wales. The koala population in South Australia and Victoria and appear to be abundant; however, the Australian Koala Foundation (AKF) argued that the exclusion of Victorian populations from protective measures was based on a misconception that the total koala population was 200,000, whereas they believed in 2012 that it was probably less than 100,000. AKF estimated in 2022 that there could be as few as 43,000 individuals. This is compared with 8 to 10 million at the start of the 20th century.The koala was heavily hunted by European settlers in the early 20th century,: 121–128  largely for its thick, soft fur. More than two million pelts are estimated to have left Australia by 1924. Pelts were in demand for use in rugs, coat linings, muffs, and as trimming on women's garments.: 125  The first successful efforts at conserving the species were initiated by the establishment of Brisbane's Lone Pine Koala Sanctuary and Sydney's Koala Park Sanctuary in the 1920s and 1930s. The owner of the latter park, Noel Burnet, became the first to successfully breed koalas and earned a reputation as the foremost contemporary authority on the marsupial.: 157–159 One of the biggest anthropogenic threats to the koala is habitat destruction and fragmentation. In coastal areas, the main cause of this is urbanisation, while in rural areas, habitat is cleared for agriculture. Native forest trees are also taken down to be made into wood products.: 104–107  In 2000, Australia ranked fifth in the world by deforestation rates, having cleared 564,800 hectares (1,396,000 acres).: 222  The distribution of the koala has shrunk by more than 50% since European arrival, largely due to fragmentation of habitat in Queensland. Nevertheless, koalas live in many protected areas.While urbanisation can pose a threat to koala populations, the animals can survive in urban areas provided enough trees are present. Urban populations have distinct vulnerabilities: collisions with vehicles and attacks by domestic dogs. To reduce road deaths, government agencies have been exploring various wildlife crossing options, such as the use of fencing to channel animals toward an underpass, in some cases adding a ledge as a walkway to an existing culvert. Dogs kill about 4,000 animals every year. Injured koalas are often taken to wildlife hospitals and rehabilitation centres. In a 30-year retrospective study performed at a New South Wales koala rehabilitation centre, trauma (usually resulting from a motor vehicle accident or dog attack) was found to be the most frequent cause of admission, followed by symptoms of Chlamydia infection.

+The koala or, inaccurately, koala bear (Phascolarctos cinereus), is an arboreal herbivorous marsupial native to Australia. It is the only extant representative of the family Phascolarctidae and its closest living relatives are the wombats. The koala is found in coastal areas of the mainland's eastern and southern regions, inhabiting Queensland, New South Wales, Victoria, and South Australia. It is easily recognisable by its stout, tailless body and large head with round, fluffy ears and large, spoon-shaped nose. The koala has a body length of 60–85 cm (24–33 in) and weighs 4–15 kg (9–33 lb). Fur colour ranges from silver grey to chocolate brown. Koalas from the northern populations are typically smaller and lighter in colour than their counterparts further south. These populations possibly are separate subspecies, but this is disputed.
+Koalas typically inhabit open Eucalyptus woodland, as the leaves of these trees make up most of their diet. Because this eucalypt diet has limited nutritional and caloric content, koalas are largely sedentary and sleep up to twenty hours a day. They are asocial animals, and bonding exists only between mothers and dependent offspring. Adult males communicate with loud bellows that intimidate rivals and attract mates. Males mark their presence with secretions from scent glands located on their chests. Being marsupials, koalas give birth to underdeveloped young that crawl into their mothers' pouches, where they stay for the first six to seven months of their lives. These young koalas, known as joeys, are fully weaned around a year old. Koalas have few natural predators and parasites, but are threatened by various pathogens, such as Chlamydiaceae bacteria and the koala retrovirus.
+Because of its distinctive appearance, the koala along with the kangaroos are recognised worldwide as symbols of Australia. They were hunted by Indigenous Australians and depicted in myths and cave art for millennia. The first recorded encounter between a European and a koala was in 1798, and an image of the animal was published in 1810 by naturalist George Perry. Botanist Robert Brown wrote the first detailed scientific description of the koala in 1814, although his work remained unpublished for 180 years. Popular artist John Gould illustrated and described the koala, introducing the species to the general British public. Further details about the animal's biology were revealed in the 19th century by several English scientists. Koalas are listed as a vulnerable species by the International Union for Conservation of Nature. Among the many threats to their existence are habitat destruction caused by agriculture, urbanisation, droughts, and associated bushfires, some related to climate change.  In February of 2022, the koala was officially listed as endangered in the Australian Capital Territory, New South Wales, and Queensland.
+
+
+== Etymology ==
+The word koala comes from the Dharug gula, meaning no water.  Although the vowel 'u' was originally written in the English orthography as "oo" (in spellings such as coola or koolah — two syllables), later became "oa" and is now pronounced in three syllables, possibly in error.Adopted by white settlers, "koala" became one of several hundred Aboriginal loan words in Australian English, where it was also commonly referred to as "native bear", later "koala bear", for its supposed resemblance to a bear. It is also one of several Aboriginal words that made it into International English, alongside e.g. "didgeridoo" and "kangaroo." The generic name, Phascolarctos, is derived from the Greek words phaskolos "pouch" and arktos "bear". The specific name, cinereus, is Latin for "ash coloured".
+
+
+== Taxonomy and evolution ==
+The koala was given its generic name Phascolarctos in 1816 by French zoologist Henri Marie Ducrotay de Blainville, who would not give it a specific name until further review. In 1819, German zoologist Georg August Goldfuss gave it the binomial Lipurus cinereus. Because Phascolarctos was published first, according to the International Code of Zoological Nomenclature, it has priority as the official name of the genus.: 58–59  French naturalist Anselme Gaëtan Desmarest proposed the name Phascolarctos fuscus in 1820, suggesting that the brown-coloured versions were a different species than the grey ones. Other names suggested by European authors included Marodactylus cinereus by Goldfuss in 1820, P. flindersii by René Primevère Lesson in 1827, and P. koala by John Edward Gray in 1827.: 45 The koala is classified with wombats (family Vombatidae) and several extinct families (including marsupial tapirs, marsupial lions and giant wombats) in the suborder Vombatiformes within the order Diprotodontia. The Vombatiformes are a sister group to a clade that includes macropods (kangaroos and wallabies) and possums. The ancestors of vombatiforms were likely arboreal, and the koala's lineage was possibly the first to branch off around 40 million years ago during the Eocene.
+
+The modern koala is the only extant member of Phascolarctidae, a family that once included several genera and species. During the Oligocene and Miocene, koalas lived in rainforests and had less specialised diets. Some species, such as the Riversleigh rainforest koala (Nimiokoala greystanesi) and some species of Perikoala, were around the same size as the modern koala, while others, such as species of Litokoala, were one-half to two-thirds its size. Like the modern species, prehistoric koalas had well developed ear structures which suggests that long-distance vocalising and sedentism developed early. During the Miocene, the Australian continent began drying out, leading to the decline of rainforests and the spread of open Eucalyptus woodlands. The genus Phascolarctos split from Litokoala in the late Miocene and had several adaptations that allowed it to live on a specialised eucalyptus diet: a shifting of the palate towards the front of the skull; larger molars and premolars; smaller pterygoid fossa; and a larger gap between the molar and the incisor teeth.: 226 P. cinereus may have emerged as a dwarf form of the giant koala (P. stirtoni). The reduction in the size of large mammals has been seen as a common phenomenon worldwide during the late Pleistocene, and several Australian mammals, such as the agile wallaby, are traditionally believed to have resulted from this dwarfing. A 2008 study questions this hypothesis, noting that P. cinereus and P. stirtoni were sympatric during the middle to late Pleistocene, and possibly as early as the Pliocene. The fossil record of the modern koala extends back at least to the middle Pleistocene.
+
+
+=== Genetics and variations ===
+Three subspecies are recognised: the Queensland koala (Phascolarctos cinereus adustus, Thomas 1923), the New South Wales koala (Phascolarctos cinereus cinereus, Goldfuss 1817), and the Victorian koala (Phascolarctos cinereus victor, Troughton 1935). These forms are distinguished by pelage colour and thickness, body size, and skull shape. The Queensland koala is the smallest of the three, with shorter, silver fur and a shorter skull. The Victorian koala is the largest, with shaggier, brown fur and a wider skull.: 7  The boundaries of these variations are based on state borders, and their status as subspecies is disputed. A 1999 genetic study suggests that the variations represent differentiated populations with limited gene flow between them and that the three subspecies comprise a single evolutionarily significant unit. Other studies have found that koala populations have high levels of inbreeding and low genetic variation. Such low genetic diversity may have been a characteristic of koala populations since the late Pleistocene. Rivers and roads have been shown to limit gene flow and contribute to the genetic differentiation of southeast Queensland populations. In April 2013, scientists from the Australian Museum and Queensland University of Technology announced they had fully sequenced the koala genome.
+
+
+== Characteristics and adaptations ==
+
+The koala is a stocky animal with a large head and vestigial or non-existent tail.: 1  It has a body length of 60–85 cm (24–33 in) and a weight of 4–15 kg (9–33 lb), making it among the largest arboreal marsupials. Koalas from Victoria are twice as heavy as those from Queensland.: 7  The species is sexually dimorphic, with males 50% larger than females. Males are further distinguished from females by their more curved noses and the presence of chest glands, which are visible as hairless patches.: 55  As in most marsupials, the male koala has a bifurcated penis, and the female has two lateral vaginas and two separate uteri.: 3   The male's penile sheath contains naturally occurring bacteria that play an important role in fertilisation. The female's pouch opening is tightened by a sphincter that keeps the young from falling out.The pelage of the koala is thicker and longer on the back, and shorter on the belly. The ears have thick fur on both the inside and outside. The back fur colour varies from light grey to chocolate brown.: 1–2   The belly fur is whitish; on the rump it is dappled whitish, and darker at the back. The koala has the most effective insulating back fur of any marsupial and is highly resilient to wind and rain, while the belly fur can reflect solar radiation. The koala's curved, sharp claws are well adapted for climbing trees. The large forepaws have two opposable digits (the first and second, which are opposable to the other three) that allow them to grasp small branches. On the hind paws, the second and third digits are fused, a typical condition for members of the Diprotodontia, and the attached claws (which are still separate) are used for grooming.: 5  As in humans and other primates, koalas have friction ridges on their paws. The animal has a sturdy skeleton and a short, muscular upper body with proportionately long upper limbs that contribute to its climbing and grasping abilities. Additional climbing strength is achieved with thigh muscles that attach to the shinbone lower than other animals.: 183  The koala has a cartilaginous pad at the end of the spine that may make it more comfortable when it perches in the fork of a tree.
+
+The koala has one of the smallest brains in proportion to body weight of any mammal,: 81  being 60% smaller than that of a typical diprotodont, weighing only 19.2 g (0.68 oz) on average. The brain's surface is fairly smooth, typical for a "primitive" animal.: 52  It occupies only 61% of the cranial cavity: 81  and is pressed against the inside surface by cerebrospinal fluid. The function of this relatively large amount of fluid is not known, although one possibility is that it acts as a shock absorber, cushioning the brain if the animal falls from a tree.: 52  The koala's small brain size may be an adaptation to the energy restrictions imposed by its diet, which is insufficient to sustain a larger brain.: 81  Because of its small brain, the koala has a limited ability to perform complex, unfamiliar behaviours. For example, when presented with plucked leaves on a flat surface, the animal cannot adapt to the change in its normal feeding routine and will not eat the leaves.: 234  The koala's olfactory senses are normal, and it is known to sniff the oils of individual branchlets to assess their edibility.: 81  Its nose is fairly large and covered in leathery skin. Its round ears provide it with good hearing, and it has a well-developed middle ear. A koala's vision is not well developed, and its relatively small eyes are unusual among marsupials in that the pupils have vertical slits. Koalas make use of a novel vocal organ to produce low-pitched sounds (see social spacing, below). Unlike typical mammalian vocal cords, which are folds in the larynx, these organs are placed in the velum (soft palate) and are called velar vocal cords.
+
+The koala has several adaptations for its eucalypt diet, which is of low nutritive value, high toxicity, and high in dietary fibre.: 76  The animal's dentition consists of the incisors and cheek teeth (a single premolar and four molars on each jaw), which are separated by a large gap (a characteristic feature of herbivorous mammals). The incisors are used for grasping leaves, which are then passed to the premolars to be snipped at the petiole before being passed to the highly cusped molars, where they are shredded into small pieces.: 46  Koalas may also store food in their cheek pouches before it is ready to be chewed. The partially worn molars of middle-aged koalas are optimal for breaking the leaves into small particles, resulting in more efficient stomach digestion and nutrient absorption in the small intestine,: 231  which digests the eucalyptus leaves to provide most of the animal's energy.: 47  A koala sometimes regurgitates the food into the mouth to be chewed a second time.Unlike kangaroos and eucalyptus-eating possums, koalas are hindgut fermenters, and their digestive retention can last for up to 100 hours in the wild or up to 200 hours in captivity.: 48  This is made possible by the extraordinary length of their caecum—200 cm (80 in) long and 10 cm (4 in) in diameter—the largest proportionally of any animal.: 188  Koalas can select which food particles to retain for longer fermentation and which to pass through. Large particles typically pass through more quickly, as they would take more time to digest.: 48  While the hindgut is proportionally larger in the koala than in other herbivores, only 10% of the animal's energy is obtained from fermentation. Since the koala gains a low amount of energy from its diet, its metabolic rate is half that of a typical mammal,: 76  although this can vary between seasons and sexes.: 49  They can digest the toxins present in eucalyptus leaves due to their production of cytochrome P450, which breaks down these poisons in the liver. The koala conserves water by passing relatively dry faecal pellets high in undigested fibre, and by storing water in the caecum.: 231 
+
+
+== Distribution and habitat ==
+The koala's geographic range covers roughly 1,000,000 km2 (390,000 sq mi), and 30 ecoregions. It extends throughout eastern and southeastern Australia, encompassing northeastern, central and southeastern Queensland, eastern New South Wales, Victoria, and southeastern South Australia. The koala was reintroduced near Adelaide and on several islands, including Kangaroo Island and French Island. The population on Magnetic Island represents the northern limit of its range. Fossil evidence shows that the koala's range stretched as far west as southwestern Western Australia during the late Pleistocene. Koalas were introduced to Western Australia at Yanchep. They were likely driven to extinction in these areas by environmental changes and hunting by Indigenous Australians.: 12–13  In South Australia, koalas were only known to exist in recent times in the lower South East,: 32  with a remnant population in the Bangham Forest between Bordertown and Naracoorte, until introduced to the Mount Lofty Ranges in the 20th-century. Doubts have been cast on Eyre's identification as koala pelt a girdle being worn by an Aboriginal man, the only evidence of their existence elsewhere in the State.
+Koalas can be found in habitats ranging from relatively open forests to woodlands, and in climates ranging from tropical to cool temperate. In semi-arid climates, they prefer riparian habitats, where nearby streams and creeks provide refuge during times of drought and extreme heat.
+
+
+== Ecology and behaviour ==
+
+
+=== Foraging and activities ===
+
+Koalas are herbivorous, and while most of their diet consists of eucalypt leaves, they can be found in trees of other genera, such as Acacia, Allocasuarina, Callitris, Leptospermum, and Melaleuca.: 73  Though the foliage of over 600 species of Eucalyptus is available, the koala shows a strong preference for around 30. They tend to choose species that have a high protein content and low proportions of fibre and lignin.: 231  The most favoured species are Eucalyptus microcorys, E. tereticornis, and E. camaldulensis, which, on average, make up more than 20% of their diet. They will also consume other species in the genus such as E. ovata, E. punctata, and E. viminalis. Despite its reputation as a fussy eater, the koala is more generalist than some other marsupial species, such as the greater glider. Since eucalypt leaves have a high water content, the koala does not need to drink often;: 74  its daily water turnover rate ranges from 71 to 91 ml/kg of body weight. Although females can meet their water requirements by eating leaves, larger males require additional water found on the ground or in tree hollows.: 231  When feeding, a koala holds onto a branch with hind paws and one forepaw while the other forepaw grasps foliage. Small koalas can move close to the end of a branch, but larger ones stay near the thicker bases.: 96  Koalas consume up to 400 grams (14 oz) of leaves a day, spread over four to six feeding sessions.: 187  Despite their adaptations to a low-energy lifestyle, they have meagre fat reserves and need to feed often.: 189 Because they get so little energy from their diet, koalas must limit their energy use and sleep or rest 20 hours a day.: 93  They are predominantly active at night and spend most of their waking hours feeding. They typically eat and sleep in the same tree, possibly for as long as a day.: 39  On very hot days, a koala may climb down to the coolest part of the tree which is cooler than the surrounding air. The koala hugs the tree to lose heat without panting. On warm days, a koala may rest with its back against a branch or lie on its stomach or back with its limbs dangling.: 93–94  During cold, wet periods, it curls itself into a tight ball to conserve energy.: 39  On windy days, a koala finds a lower, thicker branch on which to rest. While it spends most of the time in the tree, the animal descends to the ground to move to another tree.: 94  The koala usually grooms itself with its hind paws, but sometimes uses its forepaws or mouth.: 97–98 
+
+
+=== Social spacing ===
+
+Koalas are asocial animals and spend just 15 minutes a day on social behaviours. In Victoria, home ranges are small and have extensive overlap, while in central Queensland they are larger and overlap less.: 98  Koala society appears to consist of "residents" and "transients", the former being mostly adult females and the latter males. Resident males appear to be territorial and dominate others with their larger body size. Alpha males tend to establish their territories close to breeding females, while younger males are subordinate until they mature and reach full size.: 191  Adult males occasionally venture outside their home ranges; when they do so, dominant ones retain their status.: 99  When a male enters a new tree, he marks it by rubbing his chest gland against the trunk or a branch; males have occasionally been observed to dribble urine on the trunk. This scent-marking behaviour probably serves as communication, and individuals are known to sniff the base of a tree before climbing.: 54–56  Scent marking is common during aggressive encounters. Chest gland secretions are complex chemical mixtures—about 40 compounds were identified in one analysis—that vary in composition and concentration with the season and the age of the individual.
+
+Adult males communicate with loud bellows—low pitched sounds that consist of snore-like inhalations and resonant exhalations that sound like growls. These sounds are thought to be generated by unique vocal organs found in koalas. Because of their low frequency, these bellows can travel far through air and vegetation.: 56  Koalas may bellow at any time of the year, particularly during the breeding season, when it serves to attract females and possibly intimidate other males. They also bellow to advertise their presence to their neighbours when they enter a new tree.: 57  These sounds signal the male's actual body size, as well as exaggerate it; females pay more attention to bellows that originate from larger males. Female koalas bellow, though more softly, in addition to making snarls, wails, and screams. These calls are produced when in distress and when making defensive threats. Young koalas squeak when in distress. As they get older, the squeak develops into a "squawk" produced both when in distress and to show aggression. When another individual climbs over it, a koala makes a low grunt with its mouth closed. Koalas make numerous facial expressions. When snarling, wailing, or squawking, the animal curls the upper lip and points its ears forward. During screams, the lips retract and the ears are drawn back. Females bring their lips forward and raise their ears when agitated.: 102–05 Agonistic behaviour typically consists of squabbles between individuals climbing over or passing each other. This occasionally involves biting. Males that are strangers may wrestle, chase, and bite each other.: 102  In extreme situations, a male may try to displace a smaller rival from a tree. This involves the larger aggressor climbing up and attempting to corner the victim, which tries either to rush past him and climb down or to move to the end of a branch. The aggressor attacks by grasping the target by the shoulders and repeatedly biting him. Once the weaker individual is driven away, the victor bellows and marks the tree.: 101–02  Pregnant and lactating females are particularly aggressive and attack individuals that come too close. In general, however, koalas tend to avoid energy-wasting aggressive behaviour.: 191 
+
+
+=== Reproduction and development ===
+
+Koalas are seasonal breeders, and births take place from the middle of spring through the summer to early autumn, from October to May. Females in oestrus tend to hold their heads further back than usual and commonly display tremors and spasms. However, males do not appear to recognise these signs and have been observed to mount non-oestrous females. Because of his much larger size, a male can usually force himself on a female, mounting her from behind, and in extreme cases, the male may pull the female out of the tree. A female may scream and vigorously fight off her suitors but will submit to one that is dominant or is more familiar. The bellows and screams that accompany matings can attract other males to the scene, obliging the incumbent to delay mating and fight off the intruders. These fights may allow the female to assess which is dominant.: 58–60  Older males usually have accumulated scratches, scars, and cuts on the exposed parts of their noses and their eyelids.: 192 The koala's gestation period lasts 33–35 days, and a female gives birth to a single joey (although twins occur on occasion). As with all marsupials, the young are born while at the embryonic stage, weighing only 0.5 g (0.02 oz). However, they have relatively well-developed lips, forelimbs, and shoulders, as well as functioning respiratory, digestive, and urinary systems. The joey crawls into its mother's pouch to continue the rest of its development.: 61  Unlike most other marsupials, the koala does not clean her pouch.: 181 A female koala has two teats; the joey attaches itself to one of them and suckles for the rest of its pouch life.: 61  The koala has one of the lowest milk energy production rates, relative to body size, of any mammal. The female makes up for this by lactating for as long as 12 months.: 62  At seven weeks of age, the joey's head grows longer and becomes proportionally large, pigmentation begins to develop, and its sex can be determined (the scrotum appears in males and the pouch begins to develop in females). At 13 weeks, the joey weighs around 50 g (1.8 oz) and its head has doubled in size. The eyes begin to open and fine fur grows on the forehead, nape, shoulders, and arms. At 26 weeks, the fully furred animal resembles an adult and begins to poke its head out of the pouch.: 63 
+
+As the young koala approaches six months, the mother begins to prepare it for its eucalyptus diet by predigesting the leaves, producing a faecal pap that the joey eats from her cloaca. The pap is quite different in composition from regular faeces, resembling instead the contents of the caecum, which has a high concentration of bacteria. Eaten for about a month, the pap provides a supplementary source of protein at a transition time from a milk to a leaf diet.: 235  The joey fully emerges from the pouch for the first time at six or seven months of age, when it weighs 300–500 g (11–18 oz). It explores its new surroundings cautiously, clinging to its mother for support. By nine months, it weighs over 1 kg (2.2 lb) and develops its adult fur colour. Having permanently left the pouch, it rides on its mother's back for transportation, learning to climb by grasping branches.: 65–66  Gradually, it spends more time away from its mother, who becomes pregnant again after 12 months when the young is now around 2.5 kg (5.5 lb). Her bond with her previous offspring is permanently severed and she no longer allows it to suckle, but it will continue to live near her for the next 6–12 months.: 66–67 Females become sexually mature at about three years of age and can then become pregnant; in comparison, males reach sexual maturity when they are about four years old, although they can produce sperm as early as two years.: 68  While the chest glands can be functional as early as 18 months of age, males do not begin scent-marking behaviours until they reach sexual maturity. Because the offspring have a long dependent period, female koalas usually breed in alternate years. Favourable environmental factors, such as a plentiful supply of high-quality food trees, allow them to reproduce every year.: 236 
+
+
+=== Health and mortality ===
+Koalas may live from 13 to 18 years in the wild. While female koalas usually live this long, males may die sooner because of their more hazardous lives.: 69  Koalas usually survive falls from trees and immediately climb back up, but injuries and deaths from falls do occur, particularly in inexperienced young and fighting males.: 72–73  Around six years of age, the koala's chewing teeth begin to wear down and their chewing efficiency decreases. Eventually, the cusps disappear completely and the animal will die of starvation. Koalas have few predators; dingos and large pythons may prey on them; birds of prey (such as powerful owls and wedge-tailed eagles) are threats to young. Koalas are generally not subject to external parasites, other than ticks in coastal areas. Koalas may also suffer mange from the mite Sarcoptes scabiei, and skin ulcers from the bacterium Mycobacterium ulcerans, but neither is common. Internal parasites are few and largely harmless.: 71–73  These include the tapeworm Bertiella obesa, commonly found in the intestine, and the nematodes Marsupostrongylus longilarvatus and Durikainema phascolarcti, which are infrequently found in the lungs. In a three-year study of almost 600 koalas admitted to the Australian Zoo Wildlife Hospital in Queensland, 73.8% of the animals were infected with at least one species of the parasitic protozoal genus Trypanosoma, the most common of which was T. irwini.Koalas can be subject to pathogens such as Chlamydiaceae bacteria,: 74–75  which can cause keratoconjunctivitis, urinary tract infection, and reproductive tract infection.: 229–30  Such infections are widespread on the mainland, but absent in some island populations.: 114  The koala retrovirus (KoRV) may cause koala immune deficiency syndrome (KIDS) which is similar to AIDS in humans. Prevalence of KoRV in koala populations suggests a trend spreading from the north to the south of Australia. Northern populations are completely infected, while some southern populations (including Kangaroo Island) are free.The animals are vulnerable to bushfires due to their slow movements and the flammability of eucalypt trees.: 26  The koala instinctively seeks refuge in the higher branches, where it is vulnerable to intense heat and flames. Bushfires also fragment the animal's habitat, which restricts their movement and leads to population decline and loss of genetic diversity.: 209–11  Dehydration and overheating can also prove fatal.: 80  Consequently, the koala is vulnerable to the effects of climate change. Models of climate change in Australia predict warmer and drier climates, suggesting that the koala's range will shrink in the east and south to more mesic habitats.

+
+=== History ===
+
+The first written reference to the koala was recorded by John Price, servant of John Hunter, the Governor of New South Wales. Price encountered the "cullawine" on 26 January 1798, during an expedition to the Blue Mountains, although his account was not published until nearly a century later in Historical Records of Australia.: 8  In 1802, French-born explorer Francis Louis Barrallier encountered the animal when his two Aboriginal guides, returning from a hunt, brought back two koala feet they were intending to eat. Barrallier preserved the appendages and sent them and his notes to Hunter's successor, Philip Gidley King, who forwarded them to Joseph Banks. Similar to Price, Barrallier's notes were not published until 1897.: 9–10  Reports of the first capture of a live "koolah" appeared in The Sydney Gazette in August 1803. Within a few weeks Flinders' astronomer, James Inman, purchased a specimen pair for live shipment to Joseph Banks in England. They were described as 'somewhat larger than the Waumbut (Wombat)'. These encounters helped provide the impetus for King to commission the artist John Lewin to paint watercolours of the animal. Lewin painted three pictures, one of which was subsequently made into a print that was reproduced in Georges Cuvier's Le Règne Animal (The Animal Kingdom) (first published in 1817) and several European works on natural history.: 12–13, 45 Botanist Robert Brown was the first to write a detailed scientific description of the koala in 1803, based on a female specimen captured near what is now Mount Kembla in the Illawarra region of New South Wales. Austrian botanical illustrator Ferdinand Bauer drew the animal's skull, throat, feet, and paws. Brown's work remained unpublished and largely unnoticed, however, as his field books and notes remained in his possession until his death, when they were bequeathed to the British Museum (Natural History) in London. They were not identified until 1994, while Bauer's koala watercolours were not published until 1989.: 16–28  British surgeon Everard Home included details of the koala based on eyewitness accounts of William Paterson, who had befriended Brown and Bauer during their stay in New South Wales.: 33–36  Home, who in 1808 published his report in the journal Philosophical Transactions of the Royal Society, gave the animal the scientific name Didelphis coola.: 36 
+The first published image of the koala appeared in George Perry's (1810) natural history work Arcana.: 37  Perry called it the "New Holland Sloth" on account of its perceived similarities to the Central and South American tree-living mammals of the genus Bradypus. His disdain for the koala, evident in his description of the animal, was typical of the prevailing early 19th-century British attitude about the primitiveness and oddity of Australian fauna:: 40  ...  the eye is placed like that of the Sloth, very close to the mouth and nose, which gives it a clumsy awkward appearance, and void of elegance in the combination ... they have little either in their character or appearance to interest the Naturalist or Philosopher. As Nature however provides nothing in vain, we may suppose that even these torpid, senseless creatures are wisely intended to fill up one of the great links of the chain of animated nature ...
+
+Naturalist and popular artist John Gould illustrated and described the koala in his three-volume work The Mammals of Australia (1845–1863) and introduced the species, as well as other members of Australia's little-known faunal community, to the general British public.: 87–93  Comparative anatomist Richard Owen, in a series of publications on the physiology and anatomy of Australian mammals, presented a paper on the anatomy of the koala to the Zoological Society of London. In this widely cited publication, he provided the first careful description of its internal anatomy, and noted its general structural similarity to the wombat.: 94–96  English naturalist George Robert Waterhouse, curator of the Zoological Society of London, was the first to correctly classify the koala as a marsupial in the 1840s. He identified similarities between it and its fossil relatives Diprotodon and Nototherium, which had been discovered just a few years before.: 46–48  Similarly, Gerard Krefft, curator of the Australian Museum in Sydney, noted evolutionary mechanisms at work when comparing the koala to its ancestral relatives in his 1871 The Mammals of Australia.: 103–105 The first living koala in Britain arrived in 1881, purchased by the Zoological Society of London. As related by prosecutor to the society, William Alexander Forbes, the animal suffered an accidental demise when the heavy lid of a washstand fell on it and it was unable to free itself. Forbes used the opportunity to dissect the fresh female specimen, thus was able to provide explicit anatomical details on the female reproductive system, the brain, and the liver—parts not previously described by Owen, who had access only to preserved specimens.: 105–06  Scottish embryologist William Caldwell—well known in scientific circles for determining the reproductive mechanism of the platypus—described the uterine development of the koala in 1884, and used the new information to convincingly place the koala and the monotremes into an evolutionary time frame.: 111 
+
+
+=== Cultural significance ===
+
+The koala is well known worldwide and is a major draw for Australian zoos and wildlife parks.  It has been featured in advertisements, games, cartoons, and as soft toys.: ix  It benefited the national tourism industry by over an estimated billion Australian dollars in 1998, a figure that has since grown.: 201  In 1997, half of the visitors to Australia, especially those from Korea, Japan, and Taiwan, sought out zoos and wildlife parks; about 75% of European and Japanese tourists placed the koala at the top of their list of animals to see.: 216  According to biologist Stephen Jackson: "If you were to take a straw poll of the animal most closely associated with Australia, it's a fair bet that the koala would come out marginally in front of the kangaroo".: ix  Factors that contribute to the koala's enduring popularity include its childlike body proportions and teddy bear-like face.: 3 The koala is featured in the Dreamtime stories and mythology of Indigenous Australians. The Tharawal people believed that the animal helped row the boat that brought them to the continent.: 21  Another myth tells of how a tribe killed a koala and used its long intestines to create a bridge for people from other parts of the world. This narrative highlights the koala's status as a game animal and the length of its intestines.: 17  Several stories tell of how the koala lost its tail. In one, a kangaroo cuts it off to punish the koala for being lazy and greedy.: 28  Tribes in both Queensland and Victoria regarded the koala as a wise animal and sought its advice. Bidjara-speaking people credited the koala for turning barren lands into lush forests.: 41–43  The animal is also depicted in rock carvings, though not as much as some other species.: 45–46 Early European settlers in Australia considered the koala to be a prowling sloth-like animal with a "fierce and menacing look".: 143  At the beginning of the 20th century, the koala's reputation took a more positive turn, largely due to its growing popularity and depiction in several widely circulated children's stories.: 162  It is featured in Ethel Pedley's 1899 book Dot and the Kangaroo, in which it is portrayed as the "funny native bear".: 144  Artist Norman Lindsay depicted a more anthropomorphic koala in The Bulletin cartoons, starting in 1904. This character also appeared as Bunyip Bluegum in Lindsay's 1918 book The Magic Pudding.: 147  Perhaps the most famous fictional koala is Blinky Bill. Created by Dorothy Wall in 1933, the character appeared in several books and has been the subject of films, TV series, merchandise, and a 1986 environmental song by John Williamson.: 149–52  The first Australian stamp featuring a koala was issued by the Commonwealth in 1930.: 164  A television ad campaign for Australia's national airline Qantas, starting in 1967 and running for several decades, featured a live koala (voiced by Howard Morris), who complained that too many tourists were coming to Australia and concluded "I hate Qantas". The series has been ranked among the greatest commercials of all time.The song "Ode to a Koala Bear" appears on the B-side of the 1983 Paul McCartney/Michael Jackson duet single Say Say Say.: 151  A koala is the main character in Hanna-Barbera's The Kwicky Koala Show and Nippon Animation's Noozles, both of which were animated cartoons of the early 1980s. Food products shaped like the koala include the Caramello Koala chocolate bar and the bite-sized cookie snack Koala's March. Dadswells Bridge in Victoria features a tourist complex shaped like a giant koala: 155–58  and the Queensland Reds rugby team has a koala as its mascot.: 160  The Platinum Koala and Australian Silver Koala coins feature the animal on the reverse and Elizabeth II on the obverse.
+
+The drop bear is an imaginary creature in contemporary Australian folklore featuring a predatory, carnivorous version of the koala. This hoax animal is commonly spoken about in tall tales designed to scare tourists. While koalas are typically docile herbivores, drop bears are described as unusually large and vicious marsupials that inhabit treetops and attack unsuspecting people (or other prey) that walk beneath them by dropping onto their heads from above.
+
+
+=== Koala diplomacy ===
+Prince Henry, Duke of Gloucester, visited the Koala Park Sanctuary in Sydney in 1934 and was "intensely interested in the bears". His photograph, with Noel Burnet, the founder of the park, and a koala, appeared in The Sydney Morning Herald. After World War II, when tourism to Australia increased and the animals were exported to zoos overseas, the koala's international popularity rose. Several political leaders and members of royal families had their pictures taken with koalas, including Queen Elizabeth II, Prince Harry, Crown Prince Naruhito, Crown Princess Masako, Pope John Paul II, US President Bill Clinton, Soviet premier Mikhail Gorbachev and South African President Nelson Mandela: 156 At the 2014 G20 Brisbane summit, hosted by Prime Minister Tony Abbott, many world leaders including Russian President Vladimir Putin and US President Barack Obama were photographed holding koalas. The event gave rise to the term "koala diplomacy", which then became the Oxford Word of the Month for December 2016. 
+The term also includes the loan of koalas by the Australian government to overseas zoos in countries such as Singapore and Japan, as a form of "soft power diplomacy", like the "panda diplomacy" practised by China.
+
+
+== Conservation issues ==
+
+The koala was originally classified as Least Concern on the Red List, and reassessed as Vulnerable in 2014. In the Australian Capital Territory, New South Wales and Queensland, the species was listed under the EPBC Act in February 2022 as endangered by extinction. The described population was determined in 2012 to be "a species for the purposes of the EPBC Act 1999" in Federal legislation.Australian policymakers had declined a 2009 proposal to include the koala in the Environment Protection and Biodiversity Conservation Act 1999. In 2012, the Australian government listed koala populations in Queensland and New South Wales as Vulnerable, because of a 40% population decline in the former and a 33% decline in the latter. A 2017 WWF report found a 53% decline per generation in Queensland, and a 26% decline in New South Wales. The koala population in South Australia and Victoria and appear to be abundant; however, the Australian Koala Foundation (AKF) argued that the exclusion of Victorian populations from protective measures was based on a misconception that the total koala population was 200,000, whereas they believed in 2012 that it was probably less than 100,000. AKF estimated in 2022 that there could be as few as 43,000 individuals. This is compared with 8 to 10 million at the start of the 20th century.The koala was heavily hunted by European settlers in the early 20th century,: 121–128  largely for its thick, soft fur. More than two million pelts are estimated to have left Australia by 1924. Pelts were in demand for use in rugs, coat linings, muffs, and as trimming on women's garments.: 125  The first successful efforts at conserving the species were initiated by the establishment of Brisbane's Lone Pine Koala Sanctuary and Sydney's Koala Park Sanctuary in the 1920s and 1930s. The owner of the latter park, Noel Burnet, became the first to successfully breed koalas and earned a reputation as the foremost contemporary authority on the marsupial.: 157–159 One of the biggest anthropogenic threats to the koala is habitat destruction and fragmentation. In coastal areas, the main cause of this is urbanisation, while in rural areas, habitat is cleared for agriculture. Native forest trees are also taken down to be made into wood products.: 104–107  In 2000, Australia ranked fifth in the world by deforestation rates, having cleared 564,800 hectares (1,396,000 acres).: 222  The distribution of the koala has shrunk by more than 50% since European arrival, largely due to fragmentation of habitat in Queensland. Nevertheless, koalas live in many protected areas.While urbanisation can pose a threat to koala populations, the animals can survive in urban areas provided enough trees are present. Urban populations have distinct vulnerabilities: collisions with vehicles and attacks by domestic dogs. To reduce road deaths, government agencies have been exploring various wildlife crossing options, such as the use of fencing to channel animals toward an underpass, in some cases adding a ledge as a walkway to an existing culvert. Dogs kill about 4,000 animals every year. Injured koalas are often taken to wildlife hospitals and rehabilitation centres. In a 30-year retrospective study performed at a New South Wales koala rehabilitation centre, trauma (usually resulting from a motor vehicle accident or dog attack) was found to be the most frequent cause of admission, followed by symptoms of Chlamydia infection.

+The American flamingo (Phoenicopterus ruber) is a large species of flamingo closely related to the greater flamingo and Chilean flamingo native to the Neotropics. It was formerly considered conspecific with the greater flamingo, but that treatment is now widely viewed (e.g. by the American and British Ornithologists' Unions) as incorrect due to a lack of evidence. It is also known as the Caribbean flamingo, although it is also present in the Galápagos Islands. It is the only flamingo that naturally inhabits North America.
+
+
+== Distribution ==
+
+The American flamingo breeds in South America (in the Galápagos Islands of Ecuador, coastal Colombia and Venezuela, and northern Brazil), in the West Indies (Trinidad and Tobago,  Cuba, Jamaica, Hispaniola (the Dominican Republic and Haiti), The Bahamas, the Virgin Islands, and the Turks and Caicos Islands), and tropical areas of continental North America (along the northern coast of the Yucatán Peninsula in Mexico, and Cameron Parish, Louisiana, and extreme southern Florida in the United States). It is a vagrant to Puerto Rico, Anguilla, Barbados, and Honduras. The population in the Galápagos Islands differs genetically from that in the Caribbean; the Galápagos flamingos are significantly smaller, exhibit sexual dimorphism in body shape, and lay smaller eggs. They are sometimes separated as Phoenicopterus ruber glyphorhynchus.Its preferred habitats are similar to those of its relatives: saline lagoons, mudflats, and shallow, brackish coastal or inland lakes. An example habitat is the Petenes mangroves ecoregion of the Yucatán.
+
+
+=== In Florida ===
+
+The American flamingo is also found in South Florida and the Florida Keys, both of which were likely the northernmost extent of its distribution. The existence of flamingo eggs in museum collections labeled as collected from Florida indicates that they likely nested there as well. Since the arrival of Europeans, the population started to decline, up until the 1900s, where it was considered completely extirpated. During the 1950s, birds from the captive population at Hialeah Park frequently escaped, thus leading to the conclusion that all modern flamingos in Florida were escapees, although at least one bird banded as a chick in the Yucatán Peninsula has been sighted in Everglades National Park.However, a study published in 2018, involving an abandoned young flamingo named Conchy found in Key West, indicates that the occasional flamingos observed in parts of Florida are in fact natives, with some even permanently staying in Florida Bay year-round. The study also indicated that these flamingos may be increasing in population and reclaiming their lost range, slowly but steadily returning home.  Large flocks of flamingos are still known to visit Florida from time to time, most notably in 2014, when a very large flock of over 147 flamingos temporarily stayed at Stormwater Treatment Area 2, on Lake Okeechobee, with a few returning the following year. From a distance, untrained eyes can also confuse it with the roseate spoonbill.
+
+
+== Description ==
+
+The American flamingo is a large wading bird with reddish-pink plumage. Like all flamingos, it lays a single chalky-white egg on a mud mound, between May and August; incubation until hatching takes from 28 to 32 days; both parents brood their young. They may reach sexual maturity between 3 and 6 years of age, though usually they do not reproduce until they are 6 years old. Their life expectancy of 40 years is one of the longest in birds.
+Adult American flamingos are smaller on average than greater flamingos, but are the largest flamingos in the Americas. They measure from 120 to 145 cm (47 to 57 in) tall. The males weigh an average of 2.8 kg (6.2 lb), while females average 2.2 kg (4.9 lb). Most of its plumage is pink, giving rise to its earlier name of rosy flamingo and differentiating adults from the much paler greater flamingo. The wing coverts are red, and the primary and secondary flight feathers are black. The bill is pink and white with an extensive black tip. The legs are entirely pink. The call is a goose-like honking.
+
+It is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds  applies.
+
+
+== Mating and bonding behaviors ==
+Mating and bonding behaviors of P. ruber individuals have been extensively studied in captivity. The American flamingo is usually monogamous when selecting a nest site, and incubating and raising young; however, extra-pair copulations are frequent.
+
+While males usually initiate courtship, females control the process. If interest is mutual, a female walks by the male, and if the male is receptive, he  walks with her. Both parties  make synchronized movements until one member aborts this process. For low-intensity courtships, males and females  walk in unison with their heads raised. In high-intensity courtships, males and females  walk at a quick pace with their heads dropped in a false feeding posture. This high-intensity courtship stops at any point if either bird turns and the other does not follow, the heads are raised, unison movements are stopped, or the pace of movement is slowed. If the female is ultimately receptive to copulation, she stops walking and presents for the male. Long-term pairs do not frequently engage in courtship behaviors or in-group display. Pairs often stand, sleep, and eat in close proximity.
+Courtship is most often seen among individuals that change partners often or are promiscuous. A spectrum of pairing relationships is seen. Some birds have a long-term partner throughout the year; others form pairs during periods of courtship and nest attendance. How long a relationship lasts is affected by many factors, including addition and removal of adults, maturation of juveniles, and occurrence of trios and quartets. In most pairs, both individuals usually construct and defend the nest site. In rare cases, one individual undertakes both duties. Within trios, the dominant pair begins the nesting process by choosing and then defending the site.
+For trios with one male and two females, the subordinate female is tolerated by the male, but often fights with the dominant female. If two females share a nest and both lay an egg, one female will try to destroy the other egg or roll it out of the nest. For trios with two males and one female, the subordinate male is tolerated by both individuals and  often becomes the primary incubator and caregiver of the chicks. For quartets, the dominant male and two females take care of the nest, while the subordinate male remains around the periphery, never gaining access to the nest. Less animosity is observed between the dominant and subordinate females in quartets compared to trios.The egg is attended constantly and equally by alternating parents. Chicks at the nest are attended constantly by alternating parents, up to 7–11 days of age. Most attentive periods during incubation and brooding last 21–60 hours, both in the case where the ‘off-duty’ parents remain in the same lagoon to feed, or (when breeding occurs in lagoons deficient in food),  they fly to other lagoons to feed. Nest reliefs during incubation take place predominantly in late afternoon, or early morning.
+
+The time for receiving food from parents decreases from hatching to about 105 days, and the decrease is greatest after the chicks have left the nest at 7–11 days to band into crèches. The frequency and the duration of feeds by male and female partners do not differ significantly. After chicks have left the nest, feeds are predominantly nocturnal.
+
+
+== Adaptations ==
+The American flamingo has adapted to its shallow-water environment in several ways. It has evolved long legs and large webbed feet to wade and stir up the bottom of the water bed to bring up their food source to then be retrieved. To feed, it has evolved a specialized beak which is hooked downward and features marginal lamellae on the upper mandible, and inner and outer lamellae on both the upper and lower mandibles. These are adapted for filtering out differently sized food from water. Depending on the food source in their area, diets depend on the exact morphology of their beaks on what can and cannot be strained out of them. The American flamingos’ diet consists of small crustaceans, molluscs, some worms, nematodes, insects and their larvae, small fish, widgeon grass, seeds and algae. They are also known to consume mud from which they are able to get microorganisms and bacteria and obtain nutrients. It submerges its head under water to retrieve its food, and may have its head under water for long times, which requires it to hold its breath. Factors which affect the habitat choice of American flamingos are environmental temperatures, water depth, food source, accessibility of an area, and the presence of vegetation beds in feeding areas. If available food items do not meet the needs of the flamingos or the temperature is not appropriate to their requirements, they move to a better feeding or more temperate area.
+
+
+== Osmoregulation ==
+
+The role of osmoregulation—the maintenance of a precise balance of solute and water concentrations within the body—is performed by a number of bodily functions working together. In P. ruber, the kidney, the lower gastrointestinal tract, and the salt glands work together to maintain the homeostasis between ions and fluids. In mammals, the kidneys and urinary bladder are the primary organs used in osmoregulation. Birds, however, lack a urinary bladder and must compensate using these three organs.
+American flamingos are saltwater birds that ingest food with a high salt content and mostly drink salt water (with an osmolarity of usually 1000), hyperosmotic to the bodies cells . Also, though not commonly, they can drink fresh water at near-boiling temperatures from geysers. From their high-salt diet, they would lose more water and have a greater salt uptake. One way in which they osmoregulate is through the use of a salt gland, which is found in their beaks. This salt gland helps excrete excess salt from the body through the nasal openings in the flamingo's beaks. When these birds consume salt, the osmolarity increases in the blood plasma through the gut. This causes water to move out of the cells, increasing extracellular fluids. Both these changes, in turn, activate the salt glands of the bird, but before any activity occurs in the salt glands, the kidney has to reabsorb the ingested sodium from the small intestine. As seen in other saltwater birds, the fluid that is excreted has been seen to have an osmolarity greater than that of the salt water, but this varies with salt consumption and body size.As food and saltwater are ingested, sodium and water absorption begins through the walls of the gut and into the extracellular fluid. Sodium is then circulated to the kidney, where the plasma undergoes filtration by the renal glomerulus. Although birds' kidneys tend to be larger in size, they are inefficient in producing concentrated urine that is significantly hyperosmotic to their blood plasma. This form of secretion would cause dehydration from water loss. Therefore, sodium and water are reabsorbed into the plasma by renal tubules. This increase in osmotic plasma levels causes extracellular fluid volume to increase, which triggers receptors in both the brain and heart. These receptors then stimulate salt gland secretion and sodium is able to efficiently leave the body through the nares while maintaining a high body water level.Flamingos, like many other marine birds, have a high saline intake, yet even the glomular filtration rate (GFR) remains unchanged. This is because of the salt glands; high concentrations of sodium are present in the renal filtrate, but can be reabsorbed almost completely where it is excreted in high concentrations in the salt glands. Renal reabsorption can be increased through the output of the antidiuretic hormone called arginine vasotocin (AVT). AVT opens protein channels in the collection ducts of the kidney called aquaporins. Aquaporins increase the membrane permeability to water, as well as causes less water to move from the blood and into the kidney tubules.
+
+
+=== Specialized osmoregulatory cells and transport mechanisms ===
+The salt gland used by the American flamingo has two segments, a medial and lateral segment. These segments are tube shaped glands that consist of two cell types. The first is the cuboidal – peripheral cells which are small, triangular shaped cells which have only a few mitochondria. The second specialized cells are the principal cells which are found down the length of the secretory tubules, and are rich in mitochondria. These cells are similar to the mitochondria rich cells found in teleost fish.
+These cells within the salt gland employ several types of transport mechanisms that respond to osmoregulatory loads. Sodium-Potassium ATPase works with a Sodium-Chloride cotransporter (also known as the NKCC), and a basal potassium channel to secrete salt (NaCl) into secretory tubes. The ATPase uses energy from ATP to pump three sodium ions out of the cell and two potassium ions into the cell. The potassium channel allows potassium ions to diffuse out of the cell. The cotransporter pumps one sodium, potassium and two chloride ions into the cell. The chloride ion diffuses through the apical membrane into the secretory tube and the sodium follows via a paracellular route. This is what forms the hyperosmotic solution within the salt glands.
+
+
+== Circulatory system ==
+Although there has been little investigation on the specific circulatory and cardiovascular system of the phoenicopteridae, they possess the typical features of an avian circulatory system. As is seen in other aves, the flamingo's circulatory system is closed maintaining a separation of oxygenated and deoxygenated blood. This maximizes their efficiency to meet their high metabolic needs during flight. Due to this need for increased cardiac output, the avian heart tends to be larger in relation to body mass than what is seen in most mammals.
+
+
+=== Heart type and features ===
+The avian circulatory system is driven by a four-chambered, myogenic heart contained in a fibrous pericardial sac. This pericardial sac is filled with a serous fluid for lubrication. The heart itself is divided into a right and left half, each with an atrium and ventricle. The atrium and ventricles of each side are separated by atrioventricular valves which prevent back flow from one chamber to the next during contraction. Being myogenic, the hearts pace is maintained by pacemaker cells found in the sinoatrial node, located on the right atrium. The sinoatrial node uses calcium to cause a depolarizing signal transduction pathway from the atrium through right and left atrioventricular bundle which communicates contraction to the ventricles. The avian heart also consists of muscular arches that are made up of thick bundles of muscular layers. Much like a mammalian heart, the avian heart is composed of endocardial, myocardial and epicardial layers. The atrium walls tend to be thinner than the ventricle walls, due to the intense ventricular contraction used to pump oxygenated blood throughout the body.
+
+
+=== Organization of circulatory system ===
+Similar to the atrium, the arteries are composed of thick elastic muscles to withstand the pressure of the ventricular constriction, and become more rigid as they move away from the heart. Blood moves through the arteries, which undergo vasoconstriction, and into arterioles which act as a transportation system to distribute primarily oxygen as well as nutrients to all tissues of the body. As the arterioles move away from the heart and into individual organs and tissues they are further divided to increase surface area and slow blood flow. Travelling through the arterioles blood moves into the capillaries where gas exchange can occur. Capillaries are organized into capillary beds in tissues, it is here that blood exchanges oxygen for carbon dioxide waste. In the capillary beds blood flow is slowed to allow maximum diffusion of oxygen into the tissues. Once the blood has become deoxygenated it travels through venules then veins and back to the heart. Veins, unlike arteries, are thin and rigid as they do not need to withstand extreme pressure. As blood travels through the venules to the veins a funneling occurs called vasodilation bringing blood back to the heart. Once the blood reaches the heart it moves first into the right atrium, then the left ventricle to be pumped through the lungs for further gas exchange of carbon dioxide waste for oxygen. Oxygenated blood then flows from the lungs through the left atrium to the left ventricle where it is pumped out to the body. With respect to thermoregulation, the American flamingo has highly vascularized feet that use a countercurrent exchange system in their legs and feet. This method of thermoregulation keeps a constant gradient between the veins and arteries that are in close proximity in order to maintain heat within the core and minimize heat loss or gain in the extremities. Heat loss is minimized while wading in cold water, while heat gain is minimized in the hot temperatures during rest and flight.
+
+
+=== Physical and chemical properties of pumping blood ===
+Avian hearts are generally larger than mammalian hearts when compared to body mass. This adaptation allows more blood to be pumped to meet the high metabolic need associated with flight. Birds, like the flamingo, have a very efficient system for diffusing oxygen into the blood; birds have a ten times greater surface area to gas exchange volume than mammals. As a result, birds have more blood in their capillaries per unit of volume of lung than a mammal. The American flamingo's four-chambered heart is myogenic, meaning that all the muscle cells and fibers have the ability to contract rhythmically. The rhythm of contraction is controlled by the pace maker cells which have a lower threshold for depolarization. The wave of electrical depolarization initiated here is what physically starts the heart's contractions and begins pumping blood. Pumping blood creates variations in blood pressure and as a result, creates different thicknesses of blood vessels. The Law of LaPlace can be used to explain why arteries are relatively thick and veins are thin.
+
+
+=== Blood composition ===
+It was widely thought that avian blood had special properties which attributed to a very efficient extraction and transportation of oxygen in comparison to mammalian blood. This is not true; there is no real difference in the efficiency of the blood, and both mammals and birds use a hemoglobin molecule as the primary oxygen carrier with little to no difference in oxygen carrying capacity. Captivity and age have been seen to have an effect on the blood composition of the American flamingo. A decrease in white blood cell numbers was predominate with age in both captive and free living flamingos, but captive flamingos showed a higher white blood cell count than free living flamingos. One exception occurs in free living flamingos with regards to white blood cell count. The number of eosinophils in free living birds are higher because these cells are the ones that fight off parasites with which a free living bird may have more contact than a captive one. Captive birds showed higher hematocrit and red blood cell numbers than the free living flamingos, and a blood hemoglobin increase was seen with age. An increase in hemoglobin would correspond with an adults increase in metabolic needs. A smaller mean cellular volume recorded in free living flamingos coupled with similar mean hemoglobin content between captive and free living flamingos could show different oxygen diffusion characteristics between these two groups. Plasma chemistry remains relatively stable with age but lower values of protein content, uric acid, cholesterol, triglycerides, and phospholipids were seen in free living flamingos. This trend can be attributed to shortages and variances in food intake in free living flamingos.
+
+
+=== Blood composition and osmoregulation ===
+Avian erythrocytes (red blood cells) have been shown to contain approximately ten times the amount of taurine (an amino acid) as mammal erythrocytes. Taurine has a fairly large list of physiological functions; but in birds, it can have an important influence on osmoregulation. It helps the movement of ions in erythrocytes by altering the permeability of the membrane and regulating osmotic pressure within the cell. The regulation of osmotic pressure is achieved by the influx or efflux of taurine relative to changes in the osmolarity of the blood. In a hypotonic environment, cells will swell and eventually shrink; this shrinkage is due to efflux of taurine. This process also works in the opposite way in hypertonic environments. In hypertonic environments cells tend to shrink and then enlarge; this enlargement is due to an influx in taurine, effectively changing the osmotic pressure. This adaptation allows the flamingo to regulate between differences in salinity.
+
+
+== Respiratory system ==
+
+Relatively few studies have focused on the flamingo respiratory system, however little to no divergences from the standard avian anatomical design have occurred in their evolutionary history. Nevertheless, some physiological differences do occur in the flamingo and structurally similar species.
+The respiratory system is not only important for efficient gas exchange, but for thermoregulation and vocalization. Thermoregulation is important for flamingos as they generally live in warm habitats and their plush plumage increases body temperature. Heat loss is accomplished through thermal polypnea (panting), that is an increase in respiratory rate. It has been seen that the medulla, hypothalamus and mid-brain are involved in the control of panting, as well through the Hering-Breuer reflex that uses stretch receptors in the lungs, and the vagus nerve. This effect of the panting is accelerated by a process called gular fluttering; rapid flapping of membranes in the throat which is synchronized with the movements of the thorax. Both of these mechanisms promote evaporative heat loss, which allows for the bird to push out warm air and water from the body. Increases in respiratory rate would normally cause respiratory alkalosis because carbon dioxide levels are rapidly dropping in the body, but the flamingo is able to bypass this, most likely through a shunt mechanism, which allow it to still maintain a sustainable partial pressure of carbon dioxide in the blood. Since the avian integument is not equipped with sweat glands, cutaneous cooling is minimal. Because the flamingo's respiratory system is shared with multiple functions, panting must be controlled to prevent hypoxia.
+For a flamingo, having such a long neck means adapting to an unusually long trachea. Tracheas are an important area of the respiratory tract; aside from directing air in and out of the lungs, it has the largest volume of dead space in the tract. Dead space in avians is around 4.5 times higher in mammals of roughly the same size. In particular, flamingos have a trachea that is longer than its body length with 330 cartilaginous rings. As a result, they have a calculated dead space twice as high as another bird of the same size. To compensate for the elongation, they usually breathe in deep, slow patterns.One hypothesis for the bird's adaptation to respiratory alkalosis is tracheal coiling. Tracheal coiling is an overly long extension of the trachea and can often wrap around the bird's body. When faced with a heat load, birds often use thermal panting and this adaptation of tracheal coiling allows ventilation of non-exchange surfaces which can enable the bird to avoid respiratory alkalosis. The flamingo uses a "flushout" pattern of ventilation where deeper breaths are essentially mixed in with shallow panting to flush out carbon dioxide and avoid alkalosis. The increased length of the trachea provides a greater ability for respiratory evaporation and cooling off without hyperventilation.
+
+
+== Thermoregulation ==
+
+Thermoregulation is a matter of keeping a consistent body temperature regardless of the surrounding ambient temperature. Flamingos require both methods of efficient heat retention and release. Even though the American flamingo resides mainly close to the equator where there is relatively little fluctuation in temperature, seasonal and circadian variations in temperature must be accounted for.
+Like all animals, flamingos maintain a relatively constant basal metabolic rate (BMR); the metabolic rate of an animal in its thermoneutral zone (TNZ) while at rest. The BMR is a static rate which changes depending on factors such as the time of day or seasonal activity. Like most other birds, basic physiological adaptations control both heat loss in warm conditions and heat retention in cooler conditions. Using a system of countercurrent blood flow, heat is efficiently recycled through the body rather than being lost through extremities such as the legs and feet.
+Living in the equatorial region of the world, the American flamingo has little variation in seasonal temperature changes. However, as a homeothermic endotherm it is still faced with the challenge of maintaining a constant body temperature while being exposed to both the day (light period) and night (dark period) temperatures of its environments. Phoenicopterus ruber have evolved a number of thermoregulatory mechanisms to keep itself cool during the light period and warm during the dark period without expending too much energy. The American flamingo has been observed in a temperature niche between 17.8–35.2 °C (64.0–95.4 °F). In order to prevent water loss through evaporation when temperatures are elevated the flamingo will employ hyperthermia as a nonevaporative heat loss method keeping its body temperature between 40–42 °C (104–108 °F). This allows heat to leave the body by moving from an area of high body temperature to an area of a lower ambient temperature. Flamingos are also able to use evaporative heat loss methods such as, cutaneous evaporative heat loss and respiratory evaporative heat loss. During cutaneous heat loss, Phoenicopterus ruber relies on evaporation off of the skin to reduce its body temperature. This method is not very efficient as it requires evaporation to pass through the plumage. A more efficient way to reduce its body temperature is through respiratory evaporative heat loss, where the flamingo engages in panting to expel excessive body heat. During the dark period the flamingos tend to tuck their heads beneath their wing to conserve body heat. They may also elicit shivering as a means of muscular energy consumption to produce heat as needed.
+
+One of the most distinctive attribute of P. ruber is its unipedal stance, or the tendency to stand on one leg. While the purpose of this iconic posture remains ultimately unanswered, strong evidence supports its function in regulating body temperature. Like most birds, the largest amount of heat is lost through the legs and feet; having long legs can be a major disadvantage when temperatures fall and heat retention is most important. By holding one leg up against the ventral surface of the body, the flamingo lowers the surface area by which heat exits the body. Moreover, it has been observed that during periods of increased temperatures such as mid-day, flamingos will stand on both legs. Holding a bipedal stance multiplies the amount of heat lost from the legs and further regulates body temperature.
+
+
+== Migration ==
+Like other flamingo species, American flamingos will migrate short distances to ensure that they get enough food or because their current habitat has been disturbed in some way. One habitat disturbance that has been observed to cause flamingos to leave their feeding grounds is elevated water levels. These conditions make it difficult for Phoenicopterus ruber to wade, hindering their ability to access food. The flamingos will then abandon their feeding grounds in search of an alternate food source. While the flights are not as long as other migratory birds, flamingos still fly for periods without eating.
+
+
+== Metabolism ==
+The species metabolism resembles that of other salt water wading birds. They will fast when migrating to a new habitat or the chicks may not receive food daily depending on food availability. When born they are grey chicks then start to become white, then finally become pink with the food they eat.

+The green-thighed parrot (Pionites leucogaster), also known as the eastern white-bellied parrot, is a species of parrot in the family Psittacidae. The species was previously known as the white-bellied parrot (or white-bellied caique in aviculture) and contained three subspecies including the nominate race, but recent morphological work suggested the species should be split into three:
+green-thighed parrot or eastern white-bellied parrot (Pionites leucogaster)
+black-legged parrot or western white-bellied parrot (Pionites xanthomerius)
+yellow-tailed parrot or central white-bellied parrot (Pionites xanthurus)The green-thighed parrot is found in humid forest and wooded habitats in the Amazon south of the Amazon River in Brazil. It is generally fairly common throughout its range and is easily seen in a wide range of protected areas, such as the Cristalino State Park (near Alta Floresta), Xingu National Park, and Amazônia National Park in Brazil. However, it is believed that deforestation in the Amazon will cause a rapid decline in population.
+
+
+== Description ==
+
+The green-thighed parrot has an orange-yellow head and vent, a white or off-white belly, green wings, thighs and back, bluish primary feathers, a pinkish-horn beak, and pinkish legs and feet. Juveniles have brownish or black feathers on the head and nape, yellow feathers on the white belly, and greyish legs. Generally, the off-colored feathers will be lost and replaced by orange or white feathers respectively as the bird matures. Young birds also have dark brown irises, which will change to a rust or orange with age. The white breast feathers of wild caiques are often stained a chestnut brown (or "isobel") color. This may be due to tannin staining, as result of their particular affinity for bathing by rubbing their bodies against wet leaves and other plant matter.The head and nape plumage of the white-bellied parrot has been observed to fluoresce strongly under ultraviolet light.

+The central bearded dragon (Pogona vitticeps), also known as the inland bearded dragon, is a species of agamid lizard found in a wide range of arid to semiarid regions of eastern and central Australia.
+
+
+== Taxonomy ==
+Pogona vitticeps was first described by German zoologist Ernst Ahl in 1926, who placed it in the genus Amphibolurus.
+
+
+== Description ==
+
+Adults of this species can reach a total length of up to 60 cm (24 in), with the tail accounting for more than half. Some sexual dimorphism is present: males can be distinguished from females by a wider cloacal opening, a wider base of the tail, a larger head and beard, and the possession of hemipenes. Males also have more pronounced femoral pores than females (these can be seen as waxy bumps on the underside of the back legs). Bearded dragons vary widely in colour, including brown, reddish-brown, red, yellow, white and orange. They are capable of undergoing moderate changes in coloration, and scales along both sides of the throat, neck, and head form a row of narrow spines that runs down each side of the body to the tail. When feeling threatened, a bearded dragon will flatten its body against the ground, puff out its spiny throat and open its jaws to make itself appear larger. The bearded dragon is so named because of the pouch-like projection (also called the guttural pouch) on the underside of the neck and chin area which typically turns darker than the rest of the body. It also boasts spiny projections. Both of these characteristics appear similar to a human's beard. Males typically have a darker "beard" than females, and during mating season and courtship it will typically darken to near-black. The bearded dragon, like most agamid lizards, has strong legs which enable it to lift its body completely off the ground while it moves. This is done to reduce the heat taken in from the ground, as well as to increase the air flow over the belly to cool itself further.
+A study conducted in 2014 established the existence of endogenous circadian rhythm in pigmentation changes in Pogona vitticeps. If exposed to light, the dorsal skin of the lizard becomes darker, and if exposed to darkness, it becomes lighter. Under constant darkness (i.e. in the subjective night), the lizards' dorsal skin becomes the lightest.
+
+
+== Ecology and behaviour ==
+P. vitticeps is native to the semiarid woodland, arid woodland, and rocky desert regions of Central Australia. They are skilled climbers and often spend just as much time perching on tree limbs, fence posts, and in bushes as they do on the ground. They spend the morning and early evening sunning themselves on exposed branches or rocks, and retreat to shady areas or burrows during the hottest parts of the afternoon.
+Bearded dragons do not vocalize, except to hiss softly when threatened. Instead, they communicate through colour displays, posture, and physical gestures, such as arm waving and head bobbing. Bearded dragons are not social animals, but will sometimes gather in groups, especially in popular feeding or basking areas. At these times, a distinct hierarchy will emerge: the highest-ranking animals will take the best – usually the highest or sunniest – basking spots, and all other individuals arrange themselves lower down. If a low-ranking animal tries to challenge one of the dominant dragons, the dominant animal will demonstrate its superiority by bobbing its head and inflating its beard, at which point the challenger may signal submission by waving one of its arms in a slow or fast circle. If the low-ranking dragon does not submit, it will return the head bob, and a standoff or fight may ensue.
+The head bob gestures are:
+Slow bowing motion – often used by adult females to signal submission to a male
+Fast bob – used by males to signal dominance (often accompanied by an inflated and/or blackened beard)
+Violent bob – used by males just before mating; much more vigorous, and usually sets the animal's whole body in motion
+Both males and females will occasionally do fast and violent head bobs, which shows they are stressed out and need to be isolated.The male will only wave to show submission to a dominant male, whereas the female will wave, followed by a slow head bob, to show she is ready to mate. Gravid females will often refuse the advances of a male by chasing him and lying on his back.
+When under direct attack, the central bearded dragon opens its mouth to display its yellow membranes and extend its beard. It darkens the colour of its skin and flattens its body, and will hiss and make small jumps towards the attacker. Bearded dragons are not known to attack humans.Adult male bearded dragons can bite more forcefully than adult females and this difference is associated with greater head dimensions.Bearded dragons have been shown to be able to learn from watching the behaviour of conspecifics. An experiment demonstrated that after one individual was trained to open a door to reach a food item, most other bearded dragons watching this action were able to perform it as well.
+
+
+== Reproduction ==
+
+The age of sexual maturity has not been measured, although it is estimated to be about one or two years. Body size and growth rates are more important than age when determining sexual maturity in bearded dragons. Males will become very aggressive towards each other and will assert their dominance by inflating their beards and through fast head bobbing. Breeding typically occurs in the early spring. Females will lay a clutch of 11–30 oblong-shaped eggs in a shallow nest dug in the sand. After being laid, the eggs are buried and are left unattended. The eggs will hatch approximately 60 to 80 days later, depending on the incubation temperature. In captivity, they can be incubated in a styrofoam fish box, but without a male lizard, the female's eggs will not be fertile. However, a female bearded dragon can retain sperm, and thus produce fertile eggs even after being separated from a male.
+Courtship involves the male "head bobbing" to display dominance. If the female displays submissive behaviour, the male will use his mouth to grab the back of the female's head and the male will also wrap his front legs around the female's upper torso to keep her from moving. Copulation and insemination are quick. The gestation period averages about a month and a half.
+
+
+== Thermally induced sex reversal ==
+A 2015 study showed that high-temperature incubation of eggs transforms genetically male individuals into functional females. Normally their sex is determined genetically. Males have ZZ sex chromosomes, females ZW. However, when their eggs are incubated at temperatures above 32 °C (90 °F) some genetic males are born female. These females are fertile, sometimes producing more eggs than the ZW females. As juveniles, the sex reversed ZZ females resemble ZZ males with respect to relative tail length and boldness. However, as adults sex-reversed ZZ females lack the larger head and greater bite force of ZZ males and more closely resemble ZW  females.
+
+
+== Captive breeding ==
+
+Several of the Pogona genus are bred in captivity as pets; the two most popular are this species and the Rankin's dragon (Pogona henrylawsoni). The bulk of captive-bred bearded dragons today are thought to have originated from stock illegally exported from Australia during the 1970s.Captives worldwide are threatened by Agamid adenovirus, a virus that compromises the immune system of the dragon, and leads to death from other diseases. However, the majority of the infections are subclinical. Subclinically infected animals show no symptoms, but are active carriers of the disease and will infect other bearded dragons. Pet bearded dragons are commonly susceptible to Metabolic Bone Disease due to a lack of calcium in the diet, as well as impactions from ingesting sand or insects that are too large for their mouth.When the female is ready to lay eggs, she will generally stop eating, and spend most of her time trying to dig.
+A morph with underdeveloped dorsal scales is popular as a terrarium pet under the name of "leatherback bearded dragon".

+The red-fronted parrot (Poicephalus gulielmi), also known as Jardine's parrot, is a medium-sized mainly green parrot distributed across wide areas of Africa. It has three subspecies.  The extent and shade of the red or orange plumage on its head, thighs, and bend of wings vary depending on the subspecies.
+They are popular as pets, partly because of their ability to mimic speech and copy sounds. Trapping of wild birds for the pet trade is a potential threat to wild populations; however, they are protected by CITES (appendix II) making the trade, import and export of all wild-caught parrots illegal.
+
+
+== Description ==
+
+The red-fronted parrot is 28 cm (11 in) long. It is mostly green and has a short black squarish tail. Black feathers on the head, neck, back, and wings have lighter green edges giving a scalloped appearance. The lower mandible is dark grey and the upper mandible has a horn coloured base and a dark grey tip. The irises are red-orange, the eyerings are pinkish-grey, and the legs are grey-brown. The amount of red or orange on the forecrown, the bend of the wing, and thighs varies in the three subspecies but is absent in all young birds – juveniles having a dark smokey appearance above a paler beak and brown irises. The adult male and female are identical in external appearance. Gender determination of chicks is normally carried out by breeders using DNA analysis of a feather sample or by internal examination of the cloaca. This latter method is cheaper and quicker but does cause some distress to the bird.
+
+
+== Taxonomy ==
+The first red-fronted parrot to be scientifically identified was named Congo Jack. The parrot was brought back live from the Congo to the United Kingdom by Sir William Jardine's son on his return from a three-year cruise on HMS Favourite. Congo Jack became tame and whistled and screamed, rather than talk.  Sir William Jardine gave the species the binomial name Pionus Gulielmi after his son, William R.N. (Latin: Gulielmi means "William's"), and published the description in 1849.Three subspecies are now recognized:
+Poicephalus gulielmi, (Jardine 1849)
+P. g. gulielmi, (Jardine 1849) – orange-red on forehead to forecrown, wings, and thighs. Endemic to the Congo River basin. This subspecies has also been introduced to the island of Puerto Rico.
+P. g. fantiensis, Neumann 1908 – the forecrown is orange and there is an orange-red or orange on the wings, slightly smaller. Distributed from Liberia to southern Ghana.
+P. g. massaicus, Fischer & Reichenow 1884 – similar to P. gulielmi except on the head the orange-red is less extensive occurring on the forehead above the beak. Endemic to the highlands (1800 to 3500m) of southern Kenya and northern Tanzania.
+
+
+== Behaviour ==
+
+
+=== Breeding ===
+The red-fronted parrot nests in tree cavities. The eggs are white and there are usually three or four in a clutch. The female incubates the eggs for about 27 days and the chicks leave the nest about 80 days after hatching.
+
+
+=== Feeding ===
+They fly swiftly making noisy calls above the forest in pairs or small groups between their night-time roosts and feeding grounds. They feed quietly in the upper canopy of trees, where they are well camouflaged.
+
+
+== Pets ==
+
+Usually called Jardine's parrots, the red-fronted parrot is becoming an increasingly popular pet, owing to increased availability and a growing following. They are particularly playful, intelligent, and affectionate. Some speak very clearly, and imitate other birds expertly. Their size, temperament, and voice makes them good candidates for apartment dwellers, though they can give a shrill call. Captive bred birds have an endearing nature, bonding well, usually imperceptibly or only slightly favouring one member of the family more than others. They are not as "needy" as some companion species and so long as they are occupied, can be left alone for longer periods without emotional stress (allowing the owners to work for example).
+
+
+== Conservation status ==
+The wild red-fronted parrot population in Africa is difficult to estimate, because of its vast range. They are potentially threatened by trapping of wild parrots for the pet trade;
+They are listed on appendix II of The Convention on the International Trade in Endangered Species (CITES), along with almost all other parrot species. This has made the trade, import and export of all wild caught parrots illegal.

+The Senegal parrot (Poicephalus senegalus) is a parrot which is a resident breeder across a wide range of west Africa. It makes migrations within west Africa, according to the availability of the fruit, seeds and blossoms which make up its diet. It is considered a farm pest in Africa, often feeding on maize or millet. It is popular in aviculture.
+
+
+== Taxonomy ==
+
+In 1760 the French zoologist Mathurin Jacques Brisson included a description of the Senegal parrot in his Ornithologie based on a specimen collected in Senegal. He used the French name La petite perruche du Sénégal and the Latin name Psittacula senegalensis. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition he added 240 species that had been previously described by Brisson. One of these was the Senegal parrot. Linnaeus included a terse description, coined the binomial name Psittacus senegalus and cited Brisson's work. This species is now placed in the genus Poicephalus which was introduced by the English naturalist William John Swainson in 1837.There are two subspecies.
+P. s. senegalus (the nominate subspecies): this subspecies has a yellow vest; its native range includes Senegal, southern Mauritania, southern Mali to Guinea and Lobos Island.
+P. s. versteri: this subspecies has a deep-orange/red vest; its range is from the Ivory Coast and Ghana east to western Nigeria.They do not differ in behaviour, but only in the colour of the "vest". In the pet trade, the nominate subspecies is the most common though both are raised and sold as pets.
+
+
+== Description ==
+Senegal parrots are about 23 centimetres (9.1 inches) long, weigh about 120 to 170 grams (4.2 to 6.0 ounces). They have a relatively large head and beak for their overall size, and feathers form a short broad tail. Adults have a charcoal grey head, grey beak, bright yellow irises, green back and throat, and yellow underparts and rump. The yellow and green areas on a Senegal parrot's front form a V-shape resembling a yellow vest worn over green. Young Juveniles have dark grey, almost black, irises, which change to light grey.
+Senegal parrots are not sexually dimorphic, but there are some hypotheses which sometimes might help to determine the gender of adult birds:
+
+The V-shape of the vest is usually longer in females; in females the green area extends down over the chest to between the legs, whereas in males the tip of the green area ends midway down the chest.
+The female's beak and head are generally slightly smaller and narrower than the male's.
+The under-tail covert feathers (short feathers under the base of the main tail feathers) are generally mostly yellow in the male and generally mostly green in the female.
+Males are generally, but not always, larger and heavier than female birds.
+DNA testing is another way to determine the sex Senegal parrots are birds of open woodland and savanna. They flock most commonly in countries in West Africa. It is a gregarious species, continuously chattering with a range of whistling and squawking calls. Senegal parrots live an average of approximately 25–30 years in the wild, and have been known to live for 50 years in captivity.Research by Texas State University conducted in southeastern Senegal found that the parrots ate a diet of about 77% fruit, with figs (Ficus sp.), African grapes (Lannea microcarpa), and shea fruits (Vitellaria paradoxa) being the most commonly eaten. Seeds made up about 22% of the diet, and the remaining 1% consisted of flowers.
+
+
+== Behaviour ==
+
+Senegal parrots nest in holes in trees, often oil palms, usually laying three to four white eggs. The eggs are about 3 centimetres (1.2 inches) long by 2.5 centimetres (1 inch) wide. The eggs are incubated by the female, starting after the second egg has been laid, for about 27 to 28 days. Newly hatched chicks have a sparse white down and they do not open their eyes until about two to three weeks after hatching. They are dependent on the female for food and warmth who remains in the nest most of the time until about four weeks after hatching when the chicks have enough feathers for heat insulation. During this time the male brings food for the female and chicks, and guards the nest site. From about two to four weeks after hatching the female also begins to collect food for the chicks. The chicks fly out of the nest at about 9 weeks and they become independent from their parents at about 12 weeks after hatching.
+
+
+== Conservation status ==
+Because of its vast range in Africa, the wild Senegal parrot population is difficult to estimate. Nevertheless, in 1981 concerns about extensive trapping of wild parrots for the pet trade led to it being listed on appendix 2 of The Convention on the International Trade in Endangered Species (CITES), along with all parrot species. This has made the trade, import and export of all wild caught parrots illegal.
+
+
+== Aviculture ==
+
+
+=== Pets ===
+
+Hand reared Senegal parrots are one of the most popular parrots to be kept as pets, and the most popular Poicephalus parrot. Their calls are generally high pitched whistles and squawks along with mimics, but they are not as noisy as many other parrot species. They make for a good companion and are quite friendly compared to other parrot species. Senegal parrots are independent at times, needing a very fair amount of sleep during the day. Keeping two as pets can very well aid the parrots social and physical health as they have a companion.
+Wild caught Senegal parrots do not usually become tame, and do not make good pets.
+
+
+=== Breeding ===
+Senegal parrots are relatively easy to breed in captivity and there is a small industry in breeding and hand rearing Senegal parrots and other parrots for the pet trade. In aviculture Senegal parrots can start to breed at the age of 3 to 4 years in captivity, but some do not breed until age 5 years. Parent reared birds are known to breed as early as 2 years of age.Senegal parrot nest boxes can be any of a variety of sizes and shapes; but for example, a nest box about 18 inches (46 centimetres) high and 8 inches (20 centimetres) to 10 inches (25 centimetres) square would be suitable. An exit and entrance port about 2.5 inches (6.4 centimetres) in diameter would be suitable, and the birds may enlarge the port by chewing the wood. Nest boxes generally have a secure side door for inspecting the nest.

+The gray peacock-pheasant (Polyplectron bicalcaratum), also known as Burmese peacock-pheasant, is a large Asian member of the order Galliformes.
+
+
+== Taxonomy ==
+In 1747 the English naturalist George Edwards included an illustration and a description of the grey peacock-pheasant in the second volume of his A Natural History of Uncommon Birds. He used the English name "The Peacock Pheasant from China". Edwards based his hand-coloured etching on a live bird which was given to Robert Walpole, 1st Earl of Orford. When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he placed the grey peacock-pheasant with the Indian peafowl in the genus Pavo. Linnaeus included a brief description, coined the binomial name Pavo bicalcaratum and cited Edwards' work. The grey peacock-pheasant is now placed in the genus Polyplectron that was introduced in 1807 by the Dutch zoologist Coenraad Jacob Temminck. The genus name Polyplectron combines the Ancient Greek polus meaning "many" with plēktron meaning "cock's spur". The specific epithet bicalcaratum combines the Latin bi meaning "two" with calcar, calcaris meaning "spur".Although several subspecies have been described, none are currently recognised in the list of world birds maintained by Frank Gill, Pamela Rasmussen and David Donsker on behalf of the International Ornithological Committee (IOC).Other subspecies have been described in the past, but these are not now recognised:
+P. b. ghigii Delacour & Jabouille, 1924 – Ghigi's grey peacock-pheasant
+P. b. bailyi Lowe, 1925 – Lowe's grey peacock-pheasant (disputed)
+P. b. bakeri Lowe, 1925 – Northern grey peacock-pheasantOne previous subspecies, the Hainan peacock-pheasant (P. b. katsumatae), is now recognised as a separate species by the IOC.Lowe's grey peacock-pheasant was described from a captive bird of unknown provenance. Similar examples have turned up on occasion, but the validity and – if distinct – home range of this taxon remains unknown. It was theorized to inhabit western Assam or the eastern Himalayas, but this is based on conjecture.
+The phylogeny of this species is fairly enigmatic. mtDNA cytochrome b and D-loop as well as the nuclear ovomucoid intron G sequence data confirms that it belongs to a largely Continental Asian clade together with Germain's peacock-pheasant (P. germaini), but also the "brown" southern species bronze-tailed peacock-pheasant (P. chalcurum) and mountain peacock-pheasant (P. inopinatum).The ovomucin sequence seems to have evolved convergently or with a decreased mutational rate on the grey and the bronze-tailed peacock-pheasant. Though they are quite similar on the molecular level, the distance and interspersed populations of their closest relatives argue against a much more recently shared common ancestry between them versus the other two "northern" peacock-pheasants. Also, the cytochrome b and D-loop data does not support a closer relationship between P. bicalcaratus and P. chalcurum; overall, as it seems the four species' ancestors separated during a very short timespan.Note however that in the absence of dedicated phylogeographic studies, the molecular data is only of limited value in this species, the most morphologically diverse and widespread peacock-pheasant: There is no data on the origin and number of specimens, but it is unlikely that more than one or two individuals – possibly of captive origin and undeterminable subspecific allocation – were sampled. All that can be reasonably assumed is that the grey peacock-pheasant evolved on mainland Southeast Asia, probably during the Late Pliocene to Early Pleistocene 3.6-1 million years ago.
+
+
+== Description ==
+It is a large pheasant, up to 76 cm long and greyish brown with finely spotted green eyespots, an elongated bushy crest, bare pink or yellow facial skin, white throat, and grey iris, bill and legs. The sexes are rather similar, but the female is smaller, darker and less ornamented than the male. The young resemble the female.
+
+
+== Distribution and habitat ==
+The grey peacock-pheasant is distributed in lowland and hill forests of Bangladesh, Northeast India and Southeast Asia, but excluding most of Indochina as well as the entire Malayan Peninsula. The diet consists mainly of seeds, termites, fruits and invertebrates. The female usually lays two eggs.
+
+
+== Status and conservation ==
+Widespread throughout its large range, the grey peacock-pheasant is evaluated as a Species of Least Concern on the IUCN Red List of Threatened Species. It is listed on CITES Appendix II, restricting trade in wild-caught birds to preserve its stocks.

+The Palawan peacock-pheasant (Polyplectron napoleonis) is a medium-sized (up to 50 cm long) bird in the family Phasianidae.
+It is featured prominently in the culture of the indigenous people of Palawan. The bird is also depicted in the official seal of the city of Puerto Princesa.
+
+
+== Description ==
+The adult male is the most peacock-like member of the genus Polyplectron in appearance. It has an erectile crest and highly iridescent electric blue-violet, metallic green-turquoise dorsal plumage.  Its breast and ventral regions are dark black. The rectrices are wide, flat, and rigid. Their terminal edges are squared. Each tail plume and upper-tail covert is marked with highly iridescent, light reflective, ocelli. The tail is erected and expanded laterally together with the bodies of the birds. The males also raise one wing and lower the other, laterally compressing the body during pair-bonding, courtship displays as well and may also be antipredator adaptation.
+The female is slightly smaller than the male. Its contour plumage is cloudy silt in colouration. The mantle and breast are a dark sepia in coloration. The rectrices are essentially similar to those of the male, exhibiting marked adumbrations and stunning ocelli. Throughout, their plumage is earthen and difficult to distinguish from the substrate and branches. While it has similar proportions of the tail to the male, its markings are not as visually arresting. Like the male, the female has a short crest and is whitish on the throat, cheeks and eyebrows.
+Chicks are vivid ginger and cinnamon hued with prominent yellow markings. Juveniles of both sexes in the first year closely resemble their mothers. Subadult males in their second year more closely resemble their fathers but the mantle and wing coverts are marked with adumbrations analogous with the ocelli in the contour plumage of other peacock-pheasant species.
+Like other peacock-pheasants, Palawan males and some females exhibit multiple spurs on the metatarsus. These are used in anti-predator defense, foraging in leaf litter and contests with other males. The male Palawan excavates slight depressions in which it orients its body during postural display behaviors. The bird vibrates loudly via stridulation of rectrice quills. This communicative signal is both audible and as a form of seismic communication.
+Palawan peacock-pheasants are strong fliers. Their flight is swift, direct and sustained.
+
+
+== Distribution and habitat ==
+Endemic to the Philippines, the Palawan peacock-pheasant is found in the humid forests of Palawan Island in the southern part of the Philippine archipelago.
+
+
+== Taxonomy ==
+The Palawan peacock-pheasant, with its unique male plumage and distant range, represents a basal (Early? Pliocene, c.5-4 mya) offshoot of the genus Polyplectron (Kimball et al. 2001). The species is widely accepted to be monotypic, but while some males have white supercillia, giving a "double-barred" or masked appearance, others lack this trait, exhibiting dark faces, taller, denser crests and prominent white cheek spots. The birds with white supercillia are sometimes classified as a distinct subspecies, nehrkornae. The white-cheeked form may inhabit deep forest habitat with low ambient light in rolling terrain whilst the masked form appears to inhabit taller, more open forest on flatter terrain with higher ambient light. This masked form exhibits an abbreviated, more tightly compacted and highly iridescent crest.  Females of the two respective forms exhibit analogous differentiation. The female of the masked form is more prominently patterned and densely crested with paler contour plumage.
+It was long known as Polyplectron emphanum, but the name Polyplectron napoleonis was given one year before and takes priority over the newer name (Dickinson 2001).
+
+
+== Behavior and ecology ==
+Peacock-pheasants are highly invertivorous, taking isopods, earwigs, insect larvae, mollusks, centipedes and termites as well as small frogs, drupes, seeds and berries.
+They are strictly monogamous, renesting yearly. The female usually lays up to two eggs. Both parents rearing chicks for up to two years. Males act as sentinels of nest sites and are highly pugnacious during the reproductive cycle.
+
+
+== Status and conservation ==
+Due to ongoing habitat loss, small population size and limited range as well as hunting and capture for trade, the Palawan peacock-pheasant is classified as Vulnerable in the IUCN Red List of Threatened Species. It is listed on Appendix I of CITES.

+The Sumatran orangutan (Pongo abelii) is one of the three species of orangutans. Critically Endangered, and found only in the north of the Indonesian island of Sumatra, it is rarer than the Bornean orangutan but more common than the recently identified Tapanuli orangutan, also found in Sumatra. Its common name is based on two separate local words, "orang" ("people" or "person") and "hutan" ("forest"), derived from Malay, and translates as 'person of the forest'.
+
+
+== Description ==
+
+Male Sumatran orangutans grow to about 1.7 m (5.6 ft) tall and 90 kg (200 lb), while females are smaller, averaging 90 cm (3.0 ft) and 45 kg (99 lb). Compared to the Bornean species, Sumatran orangutans are thinner and have longer faces; their hair is longer with a paler red color.
+
+
+== Behaviour and ecology ==
+
+Compared with the Bornean orangutan, the Sumatran orangutan tends to be more frugivorous and especially insectivorous. Preferred fruits include figs and jackfruits. It will also eat bird eggs and small vertebrates. Sumatran orangutans spend far less time feeding on the inner bark of trees.
+Wild Sumatran orangutans in the Suaq Balimbing swamp have been observed using tools. An orangutan will break off a tree branch that is about a foot long, snap off the twigs and fray one end with its teeth. The orangutan will use the stick to dig in tree holes for termites. They will also use the stick to poke a bee's nest wall, move it around and catch the honey. In addition, orangutans use tools to eat fruit. When the fruit of the Neesia tree ripens, its hard, ridged husk softens until it falls open. Inside are seeds that the orangutans enjoy eating, but they are surrounded by fiberglass-like hairs that are painful if eaten. Tools are created differently for different uses. Sticks are often made longer or shorter depending on whether they will be used for insects or fruits. If a particular tool proves useful, the orangutan will often save it. Over time, they will collect entire "toolboxes". A Neesia-eating orangutan will select a five-inch stick, strip off its bark, and then carefully collect the hairs with it. Once the fruit is safe, the ape will eat the seeds using the stick or its fingers. Although similar swamps can be found in Borneo, wild Bornean orangutans have not been seen using these types of tools.
+
+NHNZ filmed the Sumatran orangutan for its show Wild Asia: In the Realm of the Red Ape; it showed one of them using a simple tool, a twig, to pry food from difficult places. There is also a sequence of an animal using a large leaf as an umbrella in a tropical rainstorm.
+As well as being used as tools, tree branches are a means of transportation for the Sumatran orangutan. The orangutans are the heaviest mammals to travel by tree, which makes them particularly susceptible to the changes in arboreal compliance. To deal with this, their locomotion is characterized by slow movement, long contact times, and an impressively large array of locomotors postures. Orangutans have even been shown to utilize the compliance in vertical supports to lower the cost of locomotion by swaying trees back and forth and they possess unique strategies of locomotion, moving slowly and using multiple supports to limit oscillations in compliant branches, particularly at their tips.The Sumatran orangutan is also more arboreal than its Bornean cousin; this could be because of the presence of large predators, like the Sumatran tiger. It moves through the trees by quadrumanous locomotion and semibrachiation.As of 2015, the Sumatran orangutans species only has approximately 7,000 remaining members in its population. The World Wide Fund for Nature is thus carrying out attempts to protect the species by allowing them to reproduce in the safe environment of captivity. However, this comes at a risk to the Sumatran orangutan's native behaviors in the wild. While in captivity, the orangutans are at risk to the "Captivity Effect": animals held in captivity for a prolonged period will no longer know how to behave naturally in the wild. Being provided with water, food, and shelter while in captivity and lacking all the challenges of living in the wild, captive behaviour becomes more exploratory in nature.A repertoire of 64 different gestures in use by orangutans has been identified, 29 of which are thought to have a specific meaning that can be interpreted by other orangutans the majority of the time. Six intentional meanings were identified: Affiliate/Play, Stop action, Look at/Take object, Share food/object, Co-locomote and Move away. Sumatran orangutans do not use sounds as part of their communication, which includes a lack of audible danger signals, but rather base their communication on gestures alone.
+
+
+=== Life cycle ===
+
+The Sumatran orangutan has five stages of life that are characterized by different physical and behavioral features. The first of these stages is infancy, which lasts from birth to around 2.5 years of age. The orangutan weighs between 2 and 6 kilograms. An infant is identified by light pigmented zones around the eyes and muzzle in contrast to darker pigmentation on the rest of the face as well as long hairs that protrude outward around the face. During this time, the infant is always carried by the mother during travel, it is highly dependent on the mother for food, and also sleeps in the mother's nest. The next stage is called juvenile-hood, and takes place between 2.5 and 5 years of age. The orangutan weighs between 6 and 15 kilograms, and does not look dramatically different from an infant. Although it is still mainly carried by the mother, a juvenile will often play with peers and make small exploratory trips within the vision of the mother. Towards the end of this stage, the orangutan will stop sleeping in the mother's nest and will build its own nest nearby. From the ages of 5 to 8 years of age, the orangutan is in an adolescent stage of life. The orangutan weighs around 15–30 kilograms. The light patches on the face start to disappear, and eventually the face becomes completely dark. During this time, orangutans still have constant contact with their mothers, yet they develop a stronger relationship with peers while playing in groups. They are still young and act with caution around unfamiliar adults, especially males. At 8 years of age, female orangutans are considered fully developed and begin to have offspring of their own. Males, however, enter a stage called sub-adulthood. This stage lasts from 8 to around 13 or 15 years of age, and the orangutans weigh around 30 to 50 kilograms. Their faces are completely dark, and they begin to develop cheek flanges. Their beard starts to emerge, while the hair around their face shortens, and instead of pointing outwards the face flattens along the skull. This stage marks sexual maturity in males, yet these orangutans are still socially undeveloped and will still avoid contact with adult males. Finally, male Sumatrans orangutans reach adulthood at 13 to 15 years of age. They are extremely large animals, weighing between 50 and 90 kilograms, roughly the weight of a fully grown human. They have a fully grown beard, fully developed cheek callosities, and long hair. These orangutans have reached full sexual and social maturity and now only travel alone.Female Sumatran orangutans typically live 44–53 years in the wild, while males have a slightly longer lifespan of 47–58 years. Females are able to give birth up to 53 years of age, based on studies of menopausal cycles. Both males and females are usually considered healthy even at the end of their lifespans and can be identified as such by the regular abundance of hair growth and robust cheek pads.
+
+The Sumatran orangutan is more social than its Bornean counterpart; groups gather to feed on the mass amounts of fruit on fig trees. The Sumatran orangutan community is best described as loose, not showing social or spatial exclusivity. Groups generally consist of female clusters and a preferred male mate. However, adult males generally avoid contact with other adult males. Subadult males will try to mate with any female, although mostly unsuccessfully, since mature females are easily capable of fending them off. Mature females prefer to mate with mature males. Usually, there is a specific male in a group that mature females will exhibit preference for. Male Sumatran orangutans sometimes have a delay of many years in the development of secondary sexual characteristics, such as cheek flanges and muscle mass.Males exhibit bimaturism, whereby fully flanged adult males and the smaller unflanged males are both capable of reproducing, but employ differing mating strategies to do so.The average interbirth rates for the Sumatran orangutan is 9.3 years, the longest reported among the great apes, including the Bornean orangutan. Infant orangutans will stay close to their mothers for up to three years. Even after that, the young will still associate with their mothers. Both the Sumatran and Bornean orangutans are likely to live several decades; estimated longevity is more than 50 years. The average of the first reproduction of P. abelii is around 15.4 years old. There is no indication of menopause.Nonja, thought to be the world's oldest orangutan in captivity or the wild at the time of her death, died at the Miami MetroZoo at the age of 55. Puan, an orangutan at Perth Zoo, is believed to have been 62 years old at the time of her death, making her the oldest recorded orangutan. The current oldest orangutan in the world is believed to be Bella, a female orangutan at the Hagenbeck Zoo, who is 61 years of age.
+
+
+=== Diet ===
+Sumatran orangutans are primarily frugivores, favoring fruits consisting of a large seed and surrounded by a fleshy substance, such as durians, lychees, jackfruit, breadfruit, and fig fruits. Insects are also a huge part of the orangutan's diet; the most consumed types are ants, predominantly of the genus Camponotus (at least four species indet.). Their main diet can be broken up into five categories: fruits, insects, leaf material, bark and other miscellaneous food items. Studies have shown that orangutans in the Ketambe area in Indonesia ate over 92 different kinds of fruit, 13 different kinds of leaves, 22 sorts of other vegetable material such as top-sprouts, and pseudo-bulbs of orchids. Insects included in the diet are numbered at least 17 different types. Occasionally soil from termite mounds were ingested in small quantities. When there is low ripe fruit availability, Sumatran orangutans will eat the meat of the slow loris, a nocturnal primate. Water consumption for the orangutans was ingested from natural bowls created in the trees they lived around. They even drank water from the hair on their arms when rainfall was heavy.
+
+
+==== Meat-eating ====
+
+Meat-eating happens rarely in Sumatran orangutan, and orangutans do not show a male bias in meat-eating. Research in the Ketambe area reported cases of meat-eating in wild Sumatran orangutans, of which nine cases were of orangutans eating slow lorises. The research shows, in the most recent three cases of slow lorises eaten by Sumatran orangutan, a maximum mean feeding rate of the adult orangutan for an entire adult male slow loris is 160.9 g/h and, of the infant, 142.4 g/h. No cases have been reported during mast years, which suggests orangutans take meat as a fallback for the seasonal shortage of fruits; preying on slow loris occurs more often in periods of low fruit availability. Similar to most primate species, orangutans appear to only share meat between mother and infants.
+
+
+== Genomics ==
+Orangutans have 48 chromosomes. The Sumatran orangutan genome was sequenced in January 2011, based on a captive female named Susie. Following humans and chimpanzees, the Sumatran orangutan has become the third extant hominid species to have its genome sequenced.The researchers also published less complete copies from ten wild orangutans, five from Borneo and five from Sumatra. The genetic diversity was found to be lower in Bornean orangutans (Pongo pygmaeus) than in Sumatran ones (Pongo abelii), despite the fact that Borneo is home to six or seven times as many orangutans as Sumatra. The comparison has shown these two species diverged around 400,000 years ago, more recently than was previously thought. The orangutan genome also has fewer rearrangements than the chimpanzee/human lineage.
+
+
+== Conservation ==
+
+
+=== Threats ===
+Sumatrans encounter threats such as logging (both legal and illegal), wholesale conversion of forest to agricultural land and oil palm plantations, and fragmentation by roads. Oil companies use a method of deforestation to re-use land for palm oil. This land is taken from the forest in which Sumatran orangutans live. An assessment of forest loss in the 1990s concluded that forests supporting at least 1,000 orangutans were lost each year within the Leuser Ecosystem alone.As of 2017, approximately 82.5% of the Sumatran orangutan population was strictly confined to the northernmost tip of the island, in the Aceh Province. Orangutans are rarely, if ever, found south of the Simpang Kanan River on Sumatra's west side or south of the Asahan River on the east side. The Pakpak Barat population in particular is the only Sumatran population predicted to be able to sustain orangutans in the long run, given the current effects of habitat displacement and human impact.While poaching generally is not a huge problem for the Sumatrans, occasional local hunting does decrease the population size. They have been hunted in the Northern Sumatra in the past as targets for food; although deliberate attempts to hunt the Sumatrans are rare nowadays, locals such as the Batak people are known to eat almost all vertebrates in their area. Additionally, the Sumatrans are treated as pests by Sumatran farmers, becoming targets of elimination if they are seen damaging or stealing crops. For commercial aspects, hunts for both dead or live specimens have also been recorded as an effect of the demand by European and North American zoos and institutions throughout the 20th century.Sumatran orangutans have developed a highly functioning cardiovascular system. However, with this development of hugely improved air sacs in their lungs, air sacculitis has become more prevalent among orangutans in this species. Air sacculitis is similar to streptococcal infection, e.g. strep throat in Homo sapiens. The bacterial infection is becoming increasing common in captive orangutans, due to the fact that they are exposed to the human strain of Streptococcus in captivity. At first, both strains are treated and cured with antibiotics along with rest. Yet, in 2014, a Sumatran orangutan, ten years in captivity, was the first of its species to die from Streptococcus anginosus. This remains the only known case, but raises the question of why the known human cure for Streptococcus was ineffective in this case.
+
+
+=== Conservation status ===
+
+The Sumatran orangutan is endemic to the north of Sumatra. In the wild, Sumatran orangutans only survive in the province of Nanggroe Aceh Darussalam (NAD), the northernmost tip of the island. The primate was once more widespread, as they were found farther to the south in the 19th century, such as in Jambi and Padang.
+There are small populations in the North Sumatra province along the border with NAD, particularly in the Lake Toba forests. A survey in the Lake Toba region found only two inhabited areas, Bukit Lawang (defined as the animal sanctuary) and Gunung Leuser National Park. Bukit Lawang is a jungle village, 90 kilometers northwest of Medan, situated at the eastern side of Gunung Leuser National Park. An orangutan sanctuary was set up here by a Swiss organisation in the 1970s to attempt to rehabilitate orangutans captured from the logging industry. The rangers were trained to teach the orangutans vital jungle skills to enable them to reintegrate into the forest, and provided additional supplementary food from a feeding platform. However, within the last few years supplementary feeding has ceased as the orangutan rehabilitation program has been deemed a success, the orangutans having been fully rehabilitated, and the jungle (or the remaining part of) is now at saturation point, so the sanctuary no longer accepts new orphaned orangutans.The species has been assessed as critically endangered on the IUCN Red List since 2000. From 2000-2008 it was considered one of "The World's 25 Most Endangered Primates."A survey published in March 2016 estimates a population of 14,613 Sumatran orangutans in the wild, doubling previous population estimates. A survey in 2004 estimated that around 7,300 Sumatran orangutans still live in the wild. The same study estimates a 20,552 km2 occupied area for the Sumatran orangutans, of which only an approximate area range of 8,992 km2 harbors permanent populations. Some of them are being protected in five areas in Gunung Leuser National Park; others live in unprotected areas: northwest and northeast Aceh block, West Batang Toru river, East Sarulla and Sidiangkat. A successful breeding program has been established in Bukit Tiga Puluh National Park in Jambi and Riau provinces. 
+Two strategies that are recently being considered to conserve this species are 1) rehabilitation and reintroduction of ex-captive or displaced individuals and 2) the protection of their forest habitat by preventing threats such as deforestation and hunting. The former was determined to be more cost efficient for maintaining the wild orangutan populations, but comes with longer time scale of 10–20 years. The latter approach has better prospects for ensuring long-term stability of populations. This type of habitat conservation approach has been pursued by the World Wide Fund for Nature, who joined forces with several other organizations to stop the clearing of the biggest part of remaining natural forest close to the Bukit Tigapuluh National Park.In addition to the above extant wild populations, a new population is being established in the Bukit Tigapuluh National Park (Jambi and Riau Provinces) via the re-introduction of confiscated illegal pets. This population currently numbers around 70 individuals and is reproducing. However it has been concluded that forest conservation costs twelve times less than reintroducing orangutans into the wild, and conserves more biological diversity.Orangutans have large home ranges and low population densities, which complicates conservation efforts. Population densities depend to a large degree on the abundance of fruits with soft pulp. Sumatran orangutan will commute seasonally between lowland, intermediate, and highland regions, following fruit availability. Undisturbed forests with broader altitudinal range can thus sustain larger orangutan populations; conversely, the fragmentation and extensive clearance of forest ranges breaks up this seasonal movement. Sumatra currently has one of the highest deforestation rates in the world.

+The river cooter (Pseudemys concinna) is a species of freshwater turtle in the family Emydidae. The species is native to the central and eastern United States. 
+
+
+== Geographic range ==
+P. concinna is found from Virginia south to central Georgia, west to eastern Texas, Oklahoma, and north to southern Indiana.
+
+
+== Habitat ==
+P. concinna is usually found in rivers with moderate current, as well as lakes and tidal marshes.
+
+
+== Subspecies ==
+There are two subspecies which are recognized as being valid.
+Pseudemys concinna concinna (LeConte, 1830) – eastern river cooter
+Pseudemys concinna suwanniensis Carr, 1937 – Suwannee cooter – sometimes regarded as a separate species, P. suwanniensisNota bene: A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than Pseudemys.
+The coastal plain cooter or Florida cooter (P. floridana) was formerly considered a subspecies of P. concinna, but is now considered a distinct species.
+
+
+== Name ==
+The genus Pseudemys includes several species of cooters and red-bellied turtles. Pseudemys concinna is the species known as the river cooter. The name "cooter" may have come from an African word "kuta" which means "turtle" in the Bambara and Malinké languages, brought to America by African slaves.
+
+
+== Behavior ==
+The river cooter basks on logs or sun-warmed rocks, and is frequently found in the company of other aquatic basking turtles (sliders and painteds) sometimes piled up on top of each other. All are quick to slip into the water if disturbed. Diurnal by nature, P. concinna wakes with the warming sun to bask and forage. It can move with surprising speed in the water and on land. It is not unusual for it to wander from one body of fresh water to another, but many individuals seem to develop fairly large home ranges, which they seldom or never leave. It sleeps in the water, hidden under vegetation. In areas that are quite warm it remains active all winter, but in cooler climates can become dormant during the winter for up to two months, in the mud, underwater. It doesn't breathe during this time of low metabolism, but can utilize oxygen from the water, which it takes in through the cloaca. The river cooter prefers to be well hidden under aquatic plants during the winter dormancy period or while sleeping each night.
+
+
+=== Diet ===
+The species P. concinna is highly omnivorous and will eat anything, plant or animal, dead or alive. Diet seems to be determined by available food items. While some writers feel that this species of turtle will not eat meat, predatory behavior has been observed. Although it can't swallow out of water, it will leave the water to retrieve a tasty bug or worm, returning to the water to swallow. It will also enthusiastically chase, kill and eat small fish. It has also been observed eating carrion found along the river's edge. The river cooter has tooth-like cusps in the upper jaw, probably an adaptation to aid in eating leaves and fibrous vegetation. Its primary diet includes a wide variety of aquatic plants, and some terrestrial plants that grow near the water's edge. It will happily take fallen fruits as well. In captivity, any kind of plant will be eaten, and some "meats", too. Turtles will also take calcium in a separate form, such as a cuttlebone, so that the turtle can self-regulate calcium intake.
+
+
+== Conservation status ==
+The river cooter is faced with loss of habitat, predation by animals, slaughter on the highways, and use as a food source by some people. Hatchlings are particularly vulnerable. During their overland scramble to the river, many hatchlings will be taken by avian and mammal predators. Alligators and muskrats await them in the water. Some will be taken and sold to pet stores. Populations are down in some areas, and there have been increasing reports of injured turtles, but this species as a whole is hardy, and continues to thrive. P. concinna can live 40 years or more.
+
+
+== Reproduction ==
+The mating habits of the river cooter are very similar to those of the red-eared slider. As with the other basking turtles, the males tend to be smaller than females. The male uses his long claws to flutter at the face of the much larger female. Often, the female ignores him. After detecting what may be a pheromone signal while sniffing at a female's tail, a male river cooter will court a female by swimming above her, vibrating his long nails and stroking her face. Females have also been observed doing this to initiate courtship. If the female is receptive, she will sink to the bottom of the river and allow the male to mount for mating. If she does mate, after several weeks the female crawls upon land to seek a nesting site. Females often cross highways looking for suitable nesting spots. Females will lay between 12 and 20 eggs at a time, close to water. The eggs hatch within 45 to 56 days and the hatchlings will usually stay with the nest through their first winter.
+Mating takes place in early spring. Nesting usually occurs from May to June. The female chooses a site with sandy or loamy soil, within 100 ft (30 m) of the river's edge. She looks for a rather open area, with no major obstacles for the future hatchings to negotiate on their way to the river. The nest is dug with the hind feet. She lays 10–25 or more eggs in one or more clutches. Eggs are ellipsoidal, approximately 1.5 inches (4 cm) long. Incubation time is determined by temperature, but averages 90–100 days. Hatchlings generally emerge in August or September. There have been reported instances of late clutches over-wintering and hatching in the spring. A hatchling will have a round carapace, about 1.5 inches (4 cm) diameter, that is green with bright yellow markings.
+
+
+== In the wild ==
+In the wild P. concinna feeds on aquatic plants, grasses, and algae. Younger ones tend to seek a more protein enriched diet such as aquatic invertebrates, crustaceans, and fish. Older turtles may occasionally seek prey as well, but mostly partake of a herbivorous diet.
+The river cooter can sometimes be found basking in the sun, but is very wary and will quickly retreat into the water if approached. Otherwise, it is difficult to find in the water, which may be due to its ability to breathe while fully submerged. As a result, little is known about its biology and behavior.
+The river cooter lives in a wide variety of freshwater and even brackish locations. Rivers, lakes, ponds and marshes with heavy vegetation provide ideal habitat. Large webbed feet make the river cooter an excellent swimmer, capable of negotiating moderately strong river currents of major river systems. It will collect in large numbers on peninsular floodplains associated with a river oxbow.
+
+
+== Conservation ==
+In Indiana, the river cooter is listed as an endangered species.
+
+
+=== United States federal regulations on commercial distribution ===
+A 1975 U.S. Food and Drug Administration (FDA) regulation bans the sale (for general commercial and public use) of turtle eggs and turtles with a carapace length of less than 4 inches (100 mm). This regulation comes under the Public Health Service Act and is enforced by the FDA in cooperation with State and local health jurisdictions. The ban has been effective in the U.S. since 1975 because of the public health impact of turtle-associated Salmonella. Turtles and turtle eggs found to be offered for sale in violation of this provision are subject to destruction in accordance with FDA procedures. A fine of up to $1,000 and/or imprisonment for up to one year is the penalty for those who refuse to comply with a valid final demand for destruction of such turtles or their eggs.Many stores and flea markets still sell small turtles due to an exception in the FDA regulation which allows turtles under 4 inches (100 mm) to be sold "for bona fide scientific, educational, or exhibitional purposes, other than use as pets."As with many other animals and inanimate objects, the risk of Salmonella exposure can be reduced by following basic rules of cleanliness. Small children must be taught not to put the turtle in their mouth and to wash their hands immediately after they finish "playing" with the turtle, feeding it, or changing the water.

+The Florida red-bellied cooter or Florida redbelly turtle (Pseudemys nelsoni) is a species of turtle in the family Emydidae.
+
+
+== Etymology ==
+The specific name, nelsoni, is in honor of American biologist George Nelson (born 1873).
+
+
+== Geographic range ==
+P. nelsoni is endemic to Florida, and southern Georgia. Fossils of P. nelsoni have also been found along the coast of South Carolina from the Pleistocene Epoch, indicating that the historic range of this species used to extend further north. Today, its northern counterpart, the Northern Red-bellied Cooter (Psuedemys rubriventris) occupies this region.
+
+
+== Biology ==
+The Florida redbelly cooter is mainly herbivorous, and can be found in nearly any type of aquatic habitat. It feeds on a variety of aquatic plants including waterweed (Vallisneria and Elodea), duckweed (Lemna and Wolffia), and arrowhead (Sagittaria) species. It reaches particularly high densities in spring runs, and occasionally can be found in brackish water. It appears to have an intermediate salinity tolerance compared to true freshwater forms and the highly specialized terrapin (Malachemys). This species is active year-round and spends a large portion of the day basking on logs. They are noted for sometimes laying their eggs in the nest mounds of alligators. Sex is temperature-dependent with males being born at cooler temperatures and females being born at warmer temperatures with a pivotal temperature of about 28.5 °C. The Florida redbelly is closely related to the Peninsula cooter (Pseudemys floridana) and can often be found basking on logs together.
+
+
+== Description ==
+The Florida redbelly can be distinguished from other similar turtles by its distinctive red-tinged plastron (belly) and two cusps (like teeth) on its upper beak. Like most Pseudemys turtles, this species is a fairly large river turtle. Carapace length in mature turtles can range from 20.3 to 37.5 cm (8.0 to 14.8 in). Females, which average 30.5 cm (12.0 in) in carapace length and weigh 4 kg (8.8 lb), are noticeably larger than males, which are around 25 cm (9.8 in) and 1.8 kg (4.0 lb) in mass.
+
+
+== Export ==
+Florida redbellies are commonly exported for consumption and the pet trade, with about 50% wild caught individuals and 50% captive bred.
+Most of US export statistics (as collected by the World Chelonian Trust in 2002–2005) simply describe exported turtles by the genus, Pseudemys, without identifying the species. They are exported by the million, and are mostly farm-raised.

+The northern red-bellied turtle (Pseudemys rubriventris) or American red-bellied turtle is a species of turtle in the Pseudemys (cooter) genus of the family Emydidae.
+
+
+== Description ==
+A fairly large river turtle, it averages about 29 to 30 cm (11 to 12 in) in length and weighs on average around 3 kg (6.6 lb), although large females can measure up to 40 cm (16 in) in length.
+
+
+== Distribution and habitat ==
+It is endemic to the United States. The current range of the red-bellied turtle includes a population in Massachusetts, the Plymouth red-bellied turtle, which was previously considered a distinct subspecies (Pseudemys rubriventris bangsi) as well as the coastal areas of New Jersey, Pennsylvania, Delaware, Maryland, Virginia and North Carolina.
+
+The red-bellied turtle has appeared on Pennsylvania Fish Commission lists of endangered amphibians and reptiles since 1978 (McCoy 1985). By 1985 the red-bellied turtle was known to exist in Pennsylvania only in isolated colonies in a few counties (McCoy 1985). Small (less than thirty individuals) colonies were known in Manor and Silver lakes in Bucks county, the Tinicum wetlands in Philadelphia and Delaware counties, the West Branch of Conococheague Creek in Franklin County and possibly Springton Reservoir in Delaware county (McCoy 1985).
+
+
+== Conservation ==
+The red-bellied turtle is a threatened species within Pennsylvania. However, it is listed as "Endangered" by the US Fish and Wildlife Service as well as the Division of Fisheries and Wildlife (Massachusetts).The potential threats to red-bellied turtle populations are numerous. For example: wetland loss, habitat fragmentation, pollution, collecting of turtles for pets, food or other trophies, competition with the invasive red-eared slider turtle for food, habitat, basking sites or nesting sites, and the potential for hybridization with red-eared slider turtles.
+The Massachusetts wildlife preserve foundation has started to repopulate the turtles by placing them in many south-eastern Massachusetts ponds. One example is at Long and Little Long Pond in Plymouth, Massachusetts, where the population is starting to regrow.

+The blue-crowned parakeet, blue-crowned conure,  or sharp-tailed conure (Thectocercus acuticaudatus) is a small green Neotropical parrot with a blue head and pale beak native to large parts of South America, from eastern Colombia in the north to northern Argentina in the south. They inhabit savanna-like habitats, woodland and forest margins, but avoid dense humid forest such as the Amazon.
+This species is officially called a parakeet by the AOU and by birders, though usually called conures in aviculture.
+
+
+== Taxonomy ==
+While T. acuticaudatus is the only species in the monotypic genus Thectocercus, this species has five subspecies:
+Thectocercus acuticaudatus (Vieillot 1818)
+Thectocercus acuticaudatus acuticaudatus (Vieillot 1818)
+Thectocercus acuticaudatus haemorrhous (Spix 1824)
+Thectocercus acuticaudatus koenigi (Arndt 1995)
+Thectocercus acuticaudatus neoxenus (Cory 1909)
+Thectocercus acuticaudatus neumanni (Blake and Traylor 1947)Previously, this species was part of the genus Aratinga, but that genus was split in four distinct genera once various phylogenetic studies showed that the genus, as traditionally defined, was polyphyletic.
+
+
+== Description ==
+
+The blue-crowned parakeet is a medium-sized bird measuring approximately 37 cm (14.5 in) in length and weighing between 140 and 190 g (4.9 and 6.7 oz).
+Blue-crowns are born with red coloring around the head, but blue-crowns are predominantly green, with dull blue coloring on the forehead, crown, cheeks, and ears in the nominate, but less blue in other subspecies. It has a ring of white featherless skin around each eye, though this is bright orange-yellow in wild T. acuticaudata neumanni.  The breast feathers may also be tinged with blue, though they are more commonly green to yellow-green. Closed wing coloring matches that of the body while extended wings show blue-brown, becoming chestnut on the outer flight feathers. The tail feathers are green on top, maroon to red-brown on the underside, iridescing to bright orange and scarlet under full-spectrum light. Legs are pink-brown with grey-brown claws. The upper mandible is horn-colored, tapering to a needle-sharp, grey-black tip. In the southern and western nominate and subspecies neumanni, the lower mandible is horn-colored in juveniles, fading to grey-black by the bird's second year. The remaining eastern, central and northern subspecies retain the horn-colored lower mandible throughout adulthood.
+
+
+== Breeding ==
+The blue-crowned parakeet's nest is a hole in a tree. The eggs are white and there are usually three to four in a clutch. The female incubates the eggs for 26 days, and the chicks fledge from the nest about 52 days after hatching.
+
+
+== Aviculture ==
+Blue-crowned parakeets are generally called blue-crowned conures in aviculture. They are social birds and are relatively good talkers compared to other conures.  They have become quite popular as pets, with a reputation as one of the "easier" parrots to care for. However, they are also intelligent, high-energy birds that require a lot of attention and a cage with ample room and toys. They can also be quite loud at times. Consequently, they are more appropriate companions for serious bird enthusiasts rather than the casual birdkeeper.

+The grey parrot (Psittacus erithacus), also known as the Congo grey parrot, Congo African grey parrot or African grey parrot, is an Old World parrot in the family  Psittacidae. The Timneh parrot (Psittacus timneh) once was identified as a subspecies of the grey parrot, but has since been elevated to a full species.
+
+
+== Taxonomy ==
+The grey parrot was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae. He placed it with all the other parrots in the genus Psittacus and coined the binomial name Psittacus erithacus. Linnaeus erroneously specified the type locality as "Guinea": the locality was later designated as Ghana in West Africa.  The genus name is Latin for "parrot". The specific epithet erithacus is Latin and is derived from the Ancient Greek  εριθακος (erithakos) for an unknown bird that was said to mimic human sounds, perhaps the black redstart. The species is monotypic: no subspecies are recognised.The Timneh parrot was formerly treated as a subspecies of the grey parrot but is now considered to be a separate species based mainly on the results from a genetic and morphological study published in 2007. Although Linnaeus placed all the parrots known to him in the genus Psittacus, only the grey parrot and the Timneh parrot are now assigned to this genus.
+
+
+== Description ==
+
+The grey parrot is a medium-sized, predominantly grey, black-billed parrot. Its typical weight is 400 g (14 oz), with an approximate length of 33 cm (13 in), and a wingspan of 46–52 cm (18–20+1⁄2 in). The grey colour on the head and wings is generally darker than its body. The head and body feathers have slight white edges. The tail feathers are red.
+Due to selection by parrot breeders, some grey parrots are partly or completely red. Both sexes appear similar. The colouration of juveniles is similar to that of adults, but typically their eyes are dark grey to black, in comparison to the yellow irises around dark pupils of the adult birds, and their undertail coverts are tinged with grey. Adults weigh 418–526 g (14+3⁄4–18+1⁄2 oz).Grey parrots may live for 40–60 years in captivity, although their mean lifespan in the wild appears to be shorter—approximately 23 years. They start breeding at an age of 3–5 years and lay 3-5 eggs per brood.
+
+
+== Distribution and habitat ==
+The grey parrot is native to equatorial Africa, including Angola, Cameroon, the Congo, Gabon, Ivory Coast, Ghana, Kenya, and Uganda. The species is found inside a range from Kenya to the eastern part of the Ivory Coast. Current estimates for the global population are uncertain and range from 630,000 to 13 million birds. Populations are decreasing worldwide. The species seems to favor dense forests, but can also be found at forest edges and in more open vegetation types, such as gallery and savanna forests.A population study published in 2015 found that the species had been "virtually eliminated" from Ghana with numbers declining 90 to 99% since 1992. They were found in only 10 of 42 forested areas, and three roosts that once held 700–1200 birds each, now had only 18 in total. Local people mainly blamed the pet trade and the felling of timber for the decline. Populations are thought to be stable in Cameroon. In the Congo, an estimated 15,000 are taken every year for the pet trade, from the eastern part of the country, although the annual quota is stated to be 5,000.Grey parrots have escaped or been deliberately released into Florida, U.S., but no evidence indicates that the population is breeding naturally.
+
+
+== Behaviour and ecology ==
+
+
+=== Wild bird behaviours ===
+Little is known about the behaviours and activities of these birds in the wild. In addition to a lack of research funding, it can be particularly difficult to study these birds in wild situations due to their status as prey animals, which leads them to have rather secretive personalities. It has been shown that wild greys may also imitate a wide variety of sounds they hear, much like their captive relatives. Two greys were recorded while roosting in Zaire and researchers reported that they had a repertoire of over 200 different sounds, including nine imitations of other wild bird songs and one of a bat.
+
+
+=== Diet ===
+
+They are mostly frugivorous as most of their diet consists of fruit, nuts, and seeds. The species prefers oil palm fruit and they eat flowers and tree bark, as well as insects and snails. In the wild, the grey parrot is partly a ground feeder. In captivity, they may be fed bird pellets, a variety of fruits such as pear, orange, pomegranate, apple, and banana, and vegetables such as carrot, cooked sweet potato, celery, fresh kale, peas, and green beans. They also need a source of calcium.
+
+
+=== Breeding ===
+Grey parrots are monogamous breeders who nest in tree cavities. Each mated pair of parrots needs their own tree for their nest. The hen lays three to five eggs, which she incubates for 30 days while being fed by her mate. The adults defend their nesting sites.Grey parrot chicks require feeding and care from their parents in the nest. The parents take care of them until 4–5 weeks after they are fledged. Young leave the nest at the age of 12 weeks. Little is known about the courtship behavior of this species in the wild. They weigh 12–14 g (7⁄16–1⁄2 oz) at hatching and 372–526 g (13+1⁄8–18+1⁄2 oz) when they leave their parents.
+
+		
+		
+		
+
+
+== Diseases ==
+Young grey parrots are more commonly infected by psittacine beak and feather disease than adults. Infected birds may show symptoms such as loss of appetite, fluffy feathers, sluggishness, and reduced walking abilities due to brittle bones.
+
+
+== Conservation ==
+Natural predators for this species include palm-nut vultures and several raptors. Monkeys target eggs and the young for food. Grey parrots in captivity have been observed to be susceptible to fungal infections, bacterial infections, nutritional insufficiency, malignant tumors, psittacine beak and feather disease, tapeworms, and blood-worms.Humans are by far the largest threat to wild grey populations. Between 1994 and 2003, more than 359,000 grey parrots were traded on the international market. Approximately 21% of the wild population was being harvested every year. Mortality rates are extremely high between the time they are captured and they reach the market, ranging from 60 to 66%. This species also is hunted for its meat and for its body parts, which are used in traditional medicines. As a result of the extensive harvest of wild birds, in addition to habitat loss, this species is believed to be undergoing a rapid decline in the wild and therefore, has been rated as endangered by the International Union for Conservation of Nature.In October 2016, the Convention on the International Trade of Endangered Fauna and Flora (CITES) extended the highest level of protection to grey parrots by listing the species under Appendix 1, which regulates international trade in the species.In 2021, the Kenyan government held a short amnesty, during which grey parrot owners could pay a fee to obtain a permit for their birds and facilitate legal ownership. Following the expiry of this time period, it is now illegal to own this species without a permit.
+
+
+== Relationship to humans ==
+The species is common in captivity and regularly kept by humans as a companion parrot, prized for its ability to mimic human speech, which makes it one of the most popular avian pets. An escaped pet in Japan was returned to his owner after repeating the owner's name and address.
+
+Grey parrots are notorious for mimicking noises heard in their environment and using them tirelessly. They are highly intelligent birds, needing extensive behavioral and social enrichment as well as extensive attention in captivity or else they may become distressed. Feather plucking is a common symptom seen among such distressed grey parrots, affecting up to 40% of captive individuals. They may also be prone to behavioural problems due to their sensitive nature. Social isolation hastens stress and aging.The grey parrot is a highly social species which relies on a flock-type structure, even when raised in captivity. Because they are so dependent on the other birds within their flock, much of their speech and vocal ability is acquired through interaction with the humans with whom they reside. Both wild and captive parrots have been shown to use contact calls, which allow them to interact with their flock mates and communicate information about their location, detection of predators, availability of food, and safety status. In addition, contact calls are used to form strong social bonds with their flock mates, or in the case of captive greys, with their human housemates. In captivity, they have been shown to display communicative competence, meaning they not only use human language correctly, but also in such a way that is appropriate for the social situation which they are in.
+
+
+== Intelligence and cognition ==
+Grey parrots are highly intelligent and are considered by many to be one of the most intelligent species of psittacines. Many individuals have been shown to perform at the cognitive level of a four- to six-year-old human child in some tasks. Several studies have been conducted, indicating a suite of higher-level cognitive abilities. Experiments have shown that grey parrots can learn number sequences and can learn to associate human voices with the faces of the humans who create them. It has been reported that grey parrots are capable of using existing known English words to create new labels for objects which the bird does not know the name. For example "banerry" ("banana" + "cherry") for "apple", "banana crackers" for "dried banana chips" or "yummy bread" for "cake".The American scientist Irene Pepperberg's research with Alex the parrot showed his ability to learn more than 100 words, differentiating between objects, colours, materials and shapes. Pepperberg spent several decades working with Alex, and wrote numerous scientific papers on experiments performed, indicating his advanced cognitive abilities. One such study found that Alex had the ability to add numbers as well as having a zero-like concept, similar to that of young children and apes.In addition to their striking cognitive abilities, grey parrots have displayed altruistic behavior and concern for others. Researchers found that while blue-headed macaws were unlikely to share a nut with other members of their own species, grey parrots would actively give their conspecific partner a nut, even if it meant that they would not be able to get one themselves. When the roles were reversed, their partners were overwhelmingly likely to return the favor, foregoing their own nut to their partner's benefits. This indicates not only a display of selflessness but also an act of reciprocity.
+A 2012 study demonstrated that captive grey parrots have individual musical preferences. When presented with the opportunity to choose between two different pieces of music via a touch screen monitor located in their cage, the two birds in the test consistently chose different songs, to which they then danced and sang along. Some pet grey parrots have also been observed using the music feature of smart speakers (such as Alexa or Amazon Echo) to verbally request playback of specific favored songs.Some research has shown that foot preference can be linked to the number of words a particular parrot may know and use. Researchers found that grey parrots who prefer to use their right foot showed a marked increase in the number of words within their lexicon as compared to parrots who were left-footed. Scientists postulate that parrots may have lateralization of brain function, much like mammals do.
+
+
+== Mutations ==
+Grey mutations occur naturally in the wild, such as the Blue Ino (albino), the Incomplete Ino, and the Blue varietals. The Blue Ino is all white. The Incomplete Ino has light pigmentation. The Blue has a white tail.
+Breeders from South Africa, Australia, New Zealand, and Scandinavia have bred greys intensively since the 1800s. These bred varieties include the Red Pied, F2 Pied, Grizzles, Ino, Incomplete, Parino, Lutino, Cinnamon, and Red Factor. South African bird breeder Von van Antwerpen and New Zealand partner Jaco Bosman selected F2 Pieds and created the first Red Factor Greys. They are rare, may be predominantly red-pigmented, and vary in price depending upon the extent of the red plumage displayed.

+
+Grey parrots are notorious for mimicking noises heard in their environment and using them tirelessly. They are highly intelligent birds, needing extensive behavioral and social enrichment as well as extensive attention in captivity or else they may become distressed. Feather plucking is a common symptom seen among such distressed grey parrots, affecting up to 40% of captive individuals. They may also be prone to behavioural problems due to their sensitive nature. Social isolation hastens stress and aging.The grey parrot is a highly social species which relies on a flock-type structure, even when raised in captivity. Because they are so dependent on the other birds within their flock, much of their speech and vocal ability is acquired through interaction with the humans with whom they reside. Both wild and captive parrots have been shown to use contact calls, which allow them to interact with their flock mates and communicate information about their location, detection of predators, availability of food, and safety status. In addition, contact calls are used to form strong social bonds with their flock mates, or in the case of captive greys, with their human housemates. In captivity, they have been shown to display communicative competence, meaning they not only use human language correctly, but also in such a way that is appropriate for the social situation which they are in.
+
+
+== Intelligence and cognition ==
+Grey parrots are highly intelligent and are considered by many to be one of the most intelligent species of psittacines. Many individuals have been shown to perform at the cognitive level of a four- to six-year-old human child in some tasks. Several studies have been conducted, indicating a suite of higher-level cognitive abilities. Experiments have shown that grey parrots can learn number sequences and can learn to associate human voices with the faces of the humans who create them. It has been reported that grey parrots are capable of using existing known English words to create new labels for objects which the bird does not know the name. For example "banerry" ("banana" + "cherry") for "apple", "banana crackers" for "dried banana chips" or "yummy bread" for "cake".The American scientist Irene Pepperberg's research with Alex the parrot showed his ability to learn more than 100 words, differentiating between objects, colours, materials and shapes. Pepperberg spent several decades working with Alex, and wrote numerous scientific papers on experiments performed, indicating his advanced cognitive abilities. One such study found that Alex had the ability to add numbers as well as having a zero-like concept, similar to that of young children and apes.In addition to their striking cognitive abilities, grey parrots have displayed altruistic behavior and concern for others. Researchers found that while blue-headed macaws were unlikely to share a nut with other members of their own species, grey parrots would actively give their conspecific partner a nut, even if it meant that they would not be able to get one themselves. When the roles were reversed, their partners were overwhelmingly likely to return the favor, foregoing their own nut to their partner's benefits. This indicates not only a display of selflessness but also an act of reciprocity.
+A 2012 study demonstrated that captive grey parrots have individual musical preferences. When presented with the opportunity to choose between two different pieces of music via a touch screen monitor located in their cage, the two birds in the test consistently chose different songs, to which they then danced and sang along. Some pet grey parrots have also been observed using the music feature of smart speakers (such as Alexa or Amazon Echo) to verbally request playback of specific favored songs.Some research has shown that foot preference can be linked to the number of words a particular parrot may know and use. Researchers found that grey parrots who prefer to use their right foot showed a marked increase in the number of words within their lexicon as compared to parrots who were left-footed. Scientists postulate that parrots may have lateralization of brain function, much like mammals do.
+
+
+== Mutations ==
+Grey mutations occur naturally in the wild, such as the Blue Ino (albino), the Incomplete Ino, and the Blue varietals. The Blue Ino is all white. The Incomplete Ino has light pigmentation. The Blue has a white tail.
+Breeders from South Africa, Australia, New Zealand, and Scandinavia have bred greys intensively since the 1800s. These bred varieties include the Red Pied, F2 Pied, Grizzles, Ino, Incomplete, Parino, Lutino, Cinnamon, and Red Factor. South African bird breeder Von van Antwerpen and New Zealand partner Jaco Bosman selected F2 Pieds and created the first Red Factor Greys. They are rare, may be predominantly red-pigmented, and vary in price depending upon the extent of the red plumage displayed.

+The Timneh parrot (Psittacus timneh), also known as the Timneh grey parrot or Timneh African grey parrot, is a West African parrot. Formerly classified as a subspecies of the grey parrot Psittacus erithacus timneh, it is now considered a full species Psittacus timneh. In aviculture, it is often referred to by the initials TAG and is commonly kept as a companion parrot.
+
+
+== Taxonomy ==
+The Timneh parrot was formally described in 1844 by the British zoologist and collector Louis Fraser. He coined the binomial name Psittacus timneh and specified the type locality as "Timneh country, Sierra Leone". The Temne are an ethnic group that are predominantly found in the Northern Province of Sierra Leone. The Timneh parrot was formerly classified as a subspecies of the grey parrot but is now treated as a separate species based on the results of a genetic and morphological study published in 2007.Two subspecies are recognised:
+P. t. timneh Fraser, 1844 – south Guinea to Sierra Leone, Liberia, Mali and west Ivory Coast
+P. t. princeps Alexander, 1909 – Príncipe, an island off the west coast of Africa
+
+
+== Description ==
+
+Growing to 28–33 centimetres (11–13 in) in length and weighing 275–375 grams (9.7–13.2 oz), the Timneh is a medium-sized parrot. Its plumage is mainly a mottled grey, with a white face mask and pale yellow eyes. Compared with the only other recognised Psittacus species, the grey parrot (P. erithacus), the Timneh is smaller and darker, with a dull, dark maroon (rather than crimson) tail and a horn-coloured patch on the upper mandible. Like the grey parrot, the Timneh parrot is intelligent and a skilled mimic. The Timneh parrot may be less nervous and more outgoing around human beings, and can learn to talk at a younger age than the grey parrot.
+
+
+== Distribution and habitat ==
+The Timneh parrot is endemic to the western parts of the moist Upper Guinean forests and bordering savannas of West Africa from Guinea-Bissau, Sierra Leone and southern Mali eastwards to at least 70 km east of the Bandama River in Ivory Coast. There is no natural range overlap with the grey parrot although, as both taxa are common in aviculture, escapes can occur and hybridization between greys and Timnehs has been observed in captivity. The birds typically inhabit dense forest, but are also seen at forest edges and in clearings, in gallery forest along waterways, savanna woodland and mangroves. Though they are sometimes found in cultivated areas and gardens, it is not clear whether these habitats contain self-sustaining populations; the birds may make seasonal movements out of the driest parts of their range in the dry season.
+
+
+== Status, threats and conservation ==
+Of a total estimated population of 120,000–259,000 individual birds, the largest populations are in Ivory Coast (54,000–130,000) and Liberia (50,000–100,000). In the other range countries, estimated numbers are Sierra Leone (11,000–18,000), Guinea (5,000–10,000) and Guinea-Bissau (100–1,000), with insignificant numbers in southern Mali. Surveys indicate that the species has disappeared from the forests around Mount Nimba and in Nimba County, Liberia.The Timneh parrot has been undergoing population decline both through the loss of its forest habitat and trapping for the international wild bird trade. The fragmentation and loss of forests, as well as climatic changes, has become a major factor in the food availability for parrots. The species ability to track food (such as plants and plant parts including fruits, seeds, flowers, leaf buds, and sap) and switch diets determines the species ability to cope with environmental changes; it is a contributory factor to the population decline of the Timneh parrot. change Lumped with the closely related Congo parrot as the African grey, it is one of the most popular pet birds in the United States, Europe and the Middle East due to its longevity and ability to mimic human speech.In January 2007, the CITES’ Animals Committee imposed a two-year ban on exports of Timneh parrots from Sierra Leone, Liberia, Ivory Coast and Guinea, while the importation of wild-caught birds into the EU was banned in the same year. Despite this, in 2009, Guinea exported 720 birds. The legal trade, which is monitored by CITES, may constitute only a small proportion of the total numbers trapped in the wild.In 2012, BirdLife International gave the Timneh parrot full species status on the basis of genetic, morphological, plumage and vocal differences and classified it as Endangered in 2016.

+The green araçari (Pteroglossus viridis), is a toucan, a near-passerine bird. It is found in the lowland forests of northeastern South America (the Guiana Shield), in the northeast Amazon Basin, the Guianas and the eastern Orinoco River drainage of Venezuela.  At 30–40 cm. (12–16 in) long and weighing 110–160 grams (3.9–5.7 oz.), it is the smallest aracari in its range, and among the smallest members of the toucan family.
+
+
+== Taxonomy and systematics ==
+ The green aracari was originally classified in the genus Ramphastos. Alternate names include Sclater's Araçari. The species is named for the green feathers covering its back.
+
+
+== Description ==
+Males' crowns are black, while females' are reddish brown.
+
+
+== Behaviour and ecology ==
+
+
+=== Breeding ===
+Breeding occurs from February to June.  It nests in tree cavities, producing 2–4 white eggs. The parents cooperate in rearing their young.
+
+
+=== Food and feeding ===
+Its diet consists mostly of fruit, including the fruits of Cecropia trees and the palm Oenocarpus bacaba. The serrated edges of the green aracari's large bill help the bird to grip and gather fruit. Insects are also an occasional part of the diet, giving the birds protein.
+
+
+== Pets ==
+In captivity it is the most frequently bred member of the toucan family and is the most popular as a tame hand-fed pet. It requires a large cage and toys to prevent boredom due to its active nature, and a high-fruit diet. When all these requirements are met it is an affectionate companion for many years.

+The Burmese python (Python bivittatus) is one of the largest species of snakes. It is native to a large area of Southeast Asia and is listed as Vulnerable on the IUCN Red List. Until 2009, it was considered a subspecies of the Indian python, but is now recognized as a distinct species. It is an invasive species in Florida as a result of the pet trade.
+
+
+== Description ==
+The Burmese python is a dark-colored non-venomous snake with many brown blotches bordered by black down the back.
+In the wild, Burmese pythons typically grow to 5 m (16 ft), while specimens of more than 7 m (23 ft) are unconfirmed. This species is sexually dimorphic in size; females average only slightly longer, but are considerably heavier and bulkier than the males. For example, length-weight comparisons in captive Burmese pythons for individual females have shown: at 3.47 m (11 ft 5 in) length, a specimen weighed 29 kg (64 lb), a specimen of just over 4 m (13 ft) weighed 36 kg (79 lb), a specimen of 4.5 m (15 ft) weighed 40 kg (88 lb), and a specimen of 5 m (16 ft) weighed 75 kg (165 lb). In comparison, length-weight comparisons for males found: a specimen of 2.8 m (9 ft 2 in) weighed 12 kg (26 lb), 2.97 m (9 ft 9 in) weighed 14.5 kg (32 lb), a specimen of 3 m (9.8 ft) weighed 7 kg (15 lb), and a specimen of 3.05 m (10.0 ft) weighed 18.5 kg (41 lb). In general, individuals over 5 m (16 ft) are rare. The record for maximum length of Burmese pythons is held by a female that lived at Serpent Safari for 27 years. Shortly after death, her actual length was determined to be 5.74 m (18 ft 10 in). Widely published data of specimens reported to have been several feet longer are not verified. At her death, a Burmese named "Baby" was the heaviest snake recorded in the world at the time at 182.8 kg (403 lb), much heavier than any wild snake ever measured. Her length was measured at 5.74 m (18 ft 10 in) circa 1999. The minimum size for adults is 2.35 metres (7 ft 9 in). Dwarf forms occur in Java, Bali, and Sulawesi, with an average length of 2 m (6 ft 7 in) in Bali, and a maximum of 2.5 m (8 ft 2 in) on Sulawesi. Wild individuals average 3.7 m (12 ft) long, but have been known to reach 5.74 m (18 ft 10 in).
+
+
+=== Diseases ===
+In both their native and invasive range they suffer from Raillietiella orientalis (a pentastome parasitic disease).
+
+
+== Distribution and habitat ==
+The Burmese python occurs throughout Southern and Southeast Asia, including eastern India, southeastern Nepal, western Bhutan, southeastern Bangladesh, Myanmar, Thailand, Laos, Cambodia, Vietnam, northern continental Malaysia, and southern China in Fujian, Jiangxi, Guangdong, Hainan, Guangxi, and Yunnan. It also occurs in Hong Kong, and in Indonesia on Java, southern Sulawesi, Bali, and Sumbawa. It has also been reported in Kinmen.It is an excellent swimmer and needs a permanent source of water. It lives in grasslands, marshes, swamps, rocky foothills, woodlands, river valleys, and jungles with open clearings. It is a good climber and has a prehensile tail. It can stay in water for 30 minutes but mostly stays on land.
+
+
+== As an invasive species ==
+
+Python invasion has been particularly extensive, notably across South Florida, where a large number of pythons can now be found in the Florida Everglades. Between 1996 and 2006, the Burmese python gained popularity in the pet trade, with more than 90,000 snakes imported into the U.S. The current number of Burmese pythons in the Florida Everglades may have reached a minimum viable population and become an invasive species. Hurricane Andrew in 1992 was deemed responsible for the destruction of a python-breeding facility and zoo, and these escaped snakes spread and populated areas into the Everglades. More than 1,330 have been captured in the Everglades.
+A genetic study in 2017 revealed that the python population is composed of hybrids between the Burmese python and Indian python.By 2007, the Burmese python was found in northern Florida and in the coastal areas of the Florida Panhandle. The importation of Burmese pythons was banned in the United States in January 2012 by the U.S. Department of the Interior. A 2012 report stated, "in areas where the snakes are well established, foxes, and rabbits have disappeared. Sightings of raccoons are down by 99.3%, opossums by 98.9%, and white-tailed deer by 94.1%." Road surveys between 2003 and 2011 indicated a 87.3% decrease in bobcat populations, and in some areas rabbits have not been detected at all. Experimental efforts to reintroduce rabbit populations to areas where rabbits have been completely eliminated have mostly failed "due to high (77% of mortalities) rates of predation by pythons." Bird and coyote populations may be threatened, as well as the already-rare Florida panther. In addition to this correlational relationship, the pythons have also been experimentally shown to decrease marsh rabbit populations, further suggesting they are responsible for many of the recorded mammal declines. They may also outcompete native predators for food.For example, Burmese pythons also compete with the native American alligator, and numerous instances of alligators and pythons attacking—and in some cases, preying on—each other have been reported and recorded.
+By 2011, researchers identified up to 25 species of birds from nine avian orders in the digestive tract remains of 85 Burmese pythons found in Everglades National Park. Native bird populations are suffering a negative impact from the introduction of the Burmese python in Florida; among these bird species, the wood stork is of specific concern, now listed as federally endangered.Numerous efforts have been made to eliminate the Burmese python population in the last decade. Understanding the preferred habitat of the species is needed to narrow down the python hunt. Burmese pythons have been found to select broad-leafed and low-flooded habitats. Broad-leafed habitats comprise cypress, overstory, and coniferous forest. Though aquatic marsh environments would be a great source for prey, the pythons seem to prioritize environments allowing for morphological and behavioral camouflage to be protected from predators. Also, the Burmese pythons in Florida have been found to prefer elevated habitats, since this provides the optimal conditions for nesting. In addition to elevated habitats, edge habitats are common places where Burmese pythons are found for thermoregulation, nesting, and hunting purposes.One of the Burmese python eradication movements with the biggest influence was the 2013 Python Challenge in Florida. This was a month-long contest wherein a total of 68 pythons were removed. The contest offered incentives such as prizes for longest and greatest number of captured pythons. The purpose of the challenge was to raise awareness about the invasive species, increase participation from the public and agency cooperation, and to remove as many pythons as possible from the Florida Everglades.A study from 2017 introduced a new method for identifying the presence of Burmese pythons in southern Florida; this method involves the screening of mosquito blood. Since the introduction of the Burmese python in Florida, mosquito communities use the pythons as hosts even though they are recently introduced.
+Invasive Burmese pythons also face certain physiological changes. Unlike their native South Asian counterparts who spend long periods fasting due to seasonal variation in prey availability, pythons in Florida feed year-round due to the constant availability of food. They are also vulnerable to cold stress, with winter freezes resulting in mortality rates of up to 90%. Genomic data suggests natural selection on these populations favors increased thermal tolerance as a result of these high-mortality freezes.They have carried Raillietiella orientalis (a pentastome parasitic disease) with them from Southeast Asia. Other reptiles in Florida have become infested, and the parasite appears to have become endemic.In April 2019, researchers captured and killed a large Burmese python in Florida's Big Cypress National Preserve. It was more than 5.2 m (17 ft) long, weighed 140 lb (64 kg), and contained 73 developing eggs.
+In December 2021, a Burmese python was captured in Florida that weighed 98 kg (215 lb) and had a length of 5.5 m (18 ft); it contained a record 122 developing eggs.
+
+
+== Behavior ==
+Burmese pythons are mainly nocturnal rainforest dwellers. When young, they are equally at home on the ground and in trees, but as they gain girth, they tend to restrict most of their movements to the ground. They are also excellent swimmers, being able to stay submerged for up to half an hour. Burmese pythons spend the majority of their time hidden in the underbrush. In the northern parts of its range, the Burmese python may brumate for some months during the cold season in a hollow tree, a hole in the riverbank, or under rocks. Brumation is biologically distinct from hibernation. While the behavior has similar benefits, allowing organisms to endure the winter without moving, it also involves the preparation of both male and female reproductive organs for the upcoming breeding season. The Florida population also goes through brumation.They tend to be solitary and are usually found in pairs only when mating. Burmese pythons breed in the early spring, with females laying clutches of 12–36 eggs in March or April. They remain with the eggs until they hatch, wrapping around them and twitching their muscles in such a way as to raise the ambient temperature around the eggs by several degrees. Once the hatchlings use their egg tooth to cut their way out of their eggs, no further maternal care is given. The newly hatched babies often remain inside their eggs until they are ready to complete their first shedding of skin, after which they hunt for their first meal.
+
+
+== Diet ==
+Like all snakes, the Burmese python is carnivorous. Its diet consists primarily of birds and mammals, but also includes amphibians and reptiles. It is a sit-and-wait predator, meaning it spends most of its time staying relatively still, waiting for prey to approach, then striking rapidly. The snake grabs a prey animal with its sharp teeth, then wraps its body around the animal to kill it through constriction. The python then swallows its prey whole. It is often found near human habitation due to the presence of rats, mice, and other vermin as a food source. However, its equal affinity for domesticated birds and mammals means it is often treated as a pest. In captivity, its diet consists primarily of commercially available appropriately sized rats, graduating to larger prey such as rabbits and poultry as it grows. As an invasive species in Florida, Burmese pythons primarily eat a variety of small mammals including foxes, rabbits, and raccoons. Due to their high predation levels, they have been implicated in the decline and even disappearance of many mammal species. In their invasive range, pythons also eat birds and occasionally other reptiles. Exceptionally large pythons may even require larger food items such as pigs or goats, and are known to have attacked and eaten alligators and adult deer in Florida.
+
+
+=== Digestion ===
+The digestive response of Burmese pythons to such large prey has made them a model species for digestive physiology. Its sit-and-wait hunting style is characterized by long fasting periods in between meals, with Burmese pythons typically feeding every month or two, but sometimes fasting for as long as 18 months. As digestive tissues are energetically costly to maintain, they are downregulated during fasting periods to conserve energy when they are not in use. A fasting python has a reduced stomach volume and acidity, reduced intestinal mass, and a 'normal' heart volume. After ingesting prey, the entire digestive system undergoes a massive re-modelling, with rapid hypertrophy of the intestines, production of stomach acid, and a 40% increase in mass of the ventricle of the heart to fuel the digestive process. During digestion, the snake's oxygen consumption rises drastically as well, increasing with meal size by 17 to 40 times its resting rate. This dramatic increase is a result of the energetic cost of restarting many aspects of the digestive system, from rebuilding the stomach and small intestine to producing hydrochloric acid to be secreted in the stomach. Hydrochloric acid production is a significant component of the energetic cost of digestion, as digesting whole prey items requires the animal to be broken down without the use of teeth, either for chewing or tearing into smaller pieces. To compensate, once food has been ingested, Burmese pythons begin producing large amounts of acid to make the stomach acidic enough to turn the food into a semi-liquid that can be passed through to the small intestine and undergo the rest of the digestive process.
+The energy cost is highest in the first few days after eating when these regenerative processes are most active, meaning Burmese pythons rely on existing food energy storage to digest a new meal. Overall, the entire digestive process from food intake to defecation lasts 8–14 days.
+
+
+== Conservation ==
+
+The Burmese python is listed on CITES Appendix II. It has been listed as vulnerable on the IUCN Red List since 2012, as the wild population is estimated to have declined by at least 30% in the first decade of the 21st century due to habitat loss and over-harvesting.To maintain Burmese python populations, the IUCN recommends increased conservation legislation and enforcement at the national and international levels to reduce harvesting across the snake's native range. The IUCN also recommends increased research into its population ecology and threats. In Hong Kong, it is a protected species under Wild Animals Protection Ordinance Cap 170. It is also protected in Thailand, Vietnam, China, and Indonesia. However, it is still common only in Hong Kong and Thailand, with rare to very rare statuses in the rest of its range.
+
+
+== In captivity ==
+
+Burmese pythons are often sold as pets, and are made popular by their attractive coloration and apparently easy-going nature. However, they have a rapid growth rate, and can exceed 2.1 m (6 ft 11 in) in length in a year if power fed. However this may cause health issues in the future. By age four, they will have reached their adult size, though they continue growing very slowly throughout their lives, which may exceed 20 years.
+Although the species has a reputation for docility, they are very powerful animals – capable of inflicting severe bites and even killing by constriction. They also consume large amounts of food, and due to their size, require large, often custom-built, secure enclosures. As a result, some are released into the wild, and become invasive species that devastate the environment. For this reason, some jurisdictions (including Florida, due to the python invasion in the Everglades) have placed restrictions on the keeping of Burmese pythons as pets. Violators could be imprisoned for more than seven years or fined $500,000 if convicted.
+Burmese pythons are opportunistic feeders; they eat almost any time food is offered, and often act hungry even when they have recently eaten. As a result, they are often overfed, causing obesity-related problems to be common in captive Burmese pythons.
+
+Like the much smaller ball python, Burmese pythons are known to be easygoing or timid creatures, which means that if cared for properly, they can easily adjust to living near humans.
+
+
+=== Handling ===
+Although pythons are typically afraid of people due to their great stature, and generally avoid them, special care is still required when handling them. Given their adult strength, multiple handlers (up to one person per meter of snake) are usually recommended. Some jurisdictions require owners to hold special licenses, and as with any wild animal being kept in captivity, treating them with the respect an animal of this size commands is important.
+
+
+=== Variations ===
+
+The Burmese python is frequently captive-bred for color, pattern, and more recently, size. Its amelanistic form is especially popular and is the most widely available morph. This morph is white with patterns in butterscotch yellow and burnt orange. Also, "labyrinth" specimens with maze-like patterns, khaki-colored "green", and "granite" with many small angular spots are available. Breeders have recently begun working with an island lineage of Burmese pythons. Early reports indicate that these dwarf Burmese pythons have slightly different coloring and pattern from their mainland relatives and do not grow much over 2.1 m (6 ft 11 in) in length. One of the most sought-after of these variations is the leucistic Burmese. This particular variety is very rare, being entirely bright white with no pattern and blue eyes, and has only in 2008/2009 been reproduced in captivity as the homozygous form (referred to as "super" by reptile keepers) of the co-dominant hypomelanistic trait. The caramel Burmese python has a caramel-colored pattern with "milk-chocolate" eyes.

+The Sumatran short-tailed python (Python curtus) is a species of the family Pythonidae, a nonvenomous snake native to Sumatra.
+
+
+== Taxonomy ==
+
+Python curtus was the scientific name proposed by Hermann Schlegel in 1872 for a python with a short tail from Sumatra. The type locality is Sumatra.
+
+
+== Description ==
+
+The Sumatran short-tailed python has narrow subocular scales between the bottom of the eye and the top of the labial scales. The parietal scales do not join each other. P. curtus and P. breitensteini can be distinguished by the frontal and parietal scales on the tops of their heads. In both P. brongersmai and P. breitensteini, the parietal scales join.
+Adults grow to 1.5–1.8 m (4.9–5.9 ft) in length and are heavily built. The tail is extremely short relative to the overall length. The color pattern consists of a beige, tan, or grayish-brown ground color overlaid with blotches that are brick- to blood-red in color.
+
+
+== Distribution and habitat ==
+The Sumatran short-tailed python occurs in Sumatra, Riau Archipelago, Lingga Islands, Bangka Islands, Mentawai Islands and Kalimantan.
+It inhabits rainforests, marshes, swamps, and the vicinity of river banks and streams.
+
+
+== Diet ==
+They feed on a variety of mammals and birds.
+
+
+== Reproduction ==
+Oviparous, females seldom lay more than a dozen large eggs (however, much larger clutches have been reported). The female remains coiled around the eggs during the incubation period, and may shiver to produce heat. However, this action requires energy and the female will only do so if surrounding temperatures drop below 90 °F. The hatchlings emerge after 2.5 to 3.0 months and are about 30 cm (12 in) in length.
+
+
+== Uses ==
+The species is kept as an exotic pet. They are often regarded as unpredictable and aggressive, but captive-bred individuals tend to be more docile than wild-caught specimens.
+The Sumatran short-tailed python has been extensively harvested for leather; an estimated 100,000 individuals are taken for this purpose each year. The commercial trade regards the various populations of P. curtus and P. brongersmai as a single species. Authors who elevate particular island populations to species status note that the skins are readily distinguished.

+The red kite (Milvus milvus) is a medium-large bird of prey in the family Accipitridae, which also includes many other diurnal raptors such as eagles, buzzards, and harriers. The species currently breeds in the Western Palearctic region of Europe and northwest Africa, though it formerly also occurred in northern Iran. It is resident in the milder parts of its range in western Europe and northwest Africa, but birds from northeastern and Central Europe winter further south and west, reaching south to Turkey. Vagrants have reached north to Finland and south to Israel, Libya and Gambia.
+
+
+== Taxonomy ==
+The red kite was described by the Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of his Systema Naturae under the binomial name Falco milvus. The word milvus was the Latin name for the bird. In 1799 the French naturalist Bernard Germain de Lacépède moved the species to the genus Milvus creating the tautonym.Two subspecies are recognised:
+M. m. milvus (Linnaeus, 1758) – Europe and northwest Africa to the Middle East
+M. m. fasciicauda Hartert, 1914 – Cape Verde IslandsThe subspecies M. m. fasciicauda is almost certainly extinct.The genus Milvus contains two other species: the black kite (M. migrans) and the yellow-billed kite (M. aegyptius). The red kite has been known to successfully hybridize with the black kite in captivity where both species were kept together, and in the wild on the Cape Verde Islands and infrequently in other places. The red kites on the Cape Verde Islands are (or rather were) quite distinct in morphology, being somewhat intermediate with black kites. The question whether the Cape Verde kite should be considered a distinct species (Milvus fasciicauda) or a red kite subspecies has not been settled. A mitochondrial DNA study on museum specimens suggested that Cape Verde birds did not form a monophyletic lineage among or next to red kites. This interpretation is problematic: mtDNA analysis is susceptible to hybridization events, the evolutionary history of the Cape Verde population is not known, and the genetic relationship of red kites is confusing, with geographical proximity being no indicator of genetic relatedness and the overall genetic similarity high, perhaps indicating a relict species. Given the morphological distinctness of the Cape Verde birds and that the Cape Verde population was isolated from other populations of red kites, it cannot be conclusively resolved as to whether the Cape Verde population was not a distinct subspecies (as M. migrans fasciicauda) or even species that frequently absorbed stragglers from the migrating European populations into its gene pool. The Cape Verde population became effectively extinct since 2000, all surviving birds being hybrids with black kites.The English word "kite" is from the Old English cyta which is of unknown origin. A kite is mentioned by Geoffrey Chaucer's in his Knight's Tale. The early fifteenth century Hengwrt manuscript contains the lines: "Ther cam a kyte, whil þt they were so wrothe That bar awey the boon bitwix hem bothe." The first recorded use of the word "kite" for a toy that is attached to a length of string and flown in the air dates from the seventeenth century.
+
+
+== Description ==
+
+Red kites are 60 to 70 cm (24 to 28 in) long with a 175–179 cm (69–70 in) wingspan; males weigh 800–1,200 g (28–42 oz), and females 1,000–1,300 g (35–46 oz). It is an elegant bird, soaring on long wings held at a dihedral, and long forked tail, twisting as it changes direction. The body, upper tail and wing coverts are rufous. The white primary flight feathers contrast with the black wing tips and dark secondaries. Apart from the weight difference, the sexes are similar, but juveniles have a buff breast and belly. Its call is a thin piping sound, similar to but less mewling than the common buzzard. There is a rare white leucistic form accounting for approximately 1% of hatchlings in the Welsh population, but this variation confers a disadvantage in the survival stakes.
+
+
+=== Differences between adults and juveniles ===
+Adults differ from juveniles in a number of characteristics:
+
+Adults are overall more deeply rufous, compared with the more washed out colour of juveniles;
+Adults have black breast-streaks whereas on juveniles these are pale;
+Juveniles have a less deeply forked tail, with a dark subterminal band;
+Juveniles have pale tips to all of the greater-coverts (secondary and primary) on both the upper- and under-wings, forming a long narrow pale line; adults have pale fringes to upperwing secondary-coverts only.These differences hold throughout most of the first year of a bird's life.
+
+
+== Behaviour ==
+
+
+=== Breeding ===
+
+Usually red kites first breed when they are two years old, although exceptionally they can successfully breed when they are only one year old. They are monogamous and the pair-bond in resident populations is probably maintained during the winter, particularly when the pair remain on their breeding territory. For migrant populations the fidelity to a particular nesting site means that the pair-bond is likely to be renewed each breeding season. The nest is normally placed in a fork of a large hardwood tree at a height of between 12 and 15 m (39 and 49 ft) above the ground. A pair will sometimes use a nest from the previous year and can occasionally occupy an old nest of the common buzzard. The nest is built by both sexes. The male brings dead twigs 30–50 cm (12–20 in) in length which are placed by the female. The nest is lined with grass and sometimes also with sheep's wool. Unlike the black kite, no greenery is added to the nest. Both sexes continue to add material to the nest during the incubation and nestling periods. Nests vary greatly in size and can become large when the same nest is occupied for several seasons.The eggs are laid at three-day intervals. The clutch is usually between one and three eggs but four and even five eggs have occasionally been recorded. The eggs are non-glossy with a white ground and red-brown spots. The average size is 57 mm × 45 mm (2.2 in × 1.8 in) with a calculated weight of 63 g (2.2 oz). In Britain and central Europe, laying begins at the end of March but in the Mediterranean area laying begins in early March. The eggs are mainly incubated by the female, but the male will relieve her for short periods while she feeds. The male will also bring food for the female. Incubation starts as soon as the first egg is laid. Each egg hatches after 31 to 32 days but as they hatch asynchronously a clutch of three eggs requires 38 days of incubation. The chicks are cared for by both parents. The female broods them for the first 14 days while the male brings food to the nest which the female feeds to the chicks. Later both parents bring items of food which are placed in the nest to allow the chicks to feed themselves. The nestlings begin climbing onto branches around their nest from 45 days but they rarely fledge before 48–50 days and sometimes not until they are 60–70 days of age. The young spend a further 15–20 days in the neighbourhood of the nest being fed by their parents. Only a single brood is raised each year but if the eggs are lost the female will relay.The maximum age recorded is 25 years and 8 months for a ringed bird in Germany. The longevity record for Britain and Ireland is 23 years and 10 months for a bird found dead in Wales in 2012.
+
+
+=== Food and feeding ===
+
+The red kite's diet consists mainly of small mammals such as mice, voles, shrews, young hares and rabbits. It feeds on a wide variety of carrion including sheep carcasses and dead game birds. Live birds are also taken and occasionally reptiles and amphibians. Earthworms form an important part of the diet, especially in spring. In some parts of the United Kingdom, red kites are also deliberately fed in domestic gardens, explaining the presence of red kites in urban areas. Here, up to 5% of householders have provided supplementary food for red kites, with chicken the predominant meat provided.As scavengers, red kites are particularly susceptible to poisoning. Illegal poison baits set for foxes or crows are indiscriminate and kill protected birds and other animals. There have also been a number of incidents of red kites and other raptors being targeted by wildlife criminals.In the United Kingdom, there have been several unusual instances of red kites stealing food from people in a similar manner to gulls. One such occurrence took place in Marlow, Buckinghamshire (a town near a major reintroduction site for the species in the UK in the nearby village of Stokenchurch), in which Red Kites swooped down to steal sandwiches from people in one of the town's parks.
+
+
+== Distribution and status ==
+
+Red kites inhabit broadleaf woodlands, valleys and wetland edges, to 800 metres (2,600 ft). They are native to the western Palearctic, with the European population of 19,000–25,000 pairs encompassing 95% of its global breeding range. It breeds from Spain and Portugal east into central Europe and Ukraine, north to southern Sweden, Latvia and the UK, and south to southern Italy. There is a population in northern Morocco. Northern birds move south in winter, mostly staying in the west of the breeding range, but also to eastern Turkey, northern Tunisia and Algeria. The three largest populations (in Germany, France and Spain, which together hold more than 75% of the global population) declined between 1990 and 2000, and overall the species declined by almost 20% over the ten years. The main threats to red kites are poisoning, through illegal direct poisoning and indirect poisoning from pesticides, particularly in the wintering ranges in France and Spain, and changes in agricultural practices causing a reduction in food resources. Other threats include electrocution, hunting and trapping, deforestation, egg-collection (on a local scale) and possibly competition with the generally more successful black kite M. migrans.
+
+
+=== Continental Europe ===
+
+German populations declined by 25%–30% between 1991 and 1997, but have remained stable since. The populations of the northern foothills of the Harz Mountains (the most densely populated part of its range) suffered an estimated 50% decline from 1991 to 2001. In Spain, the species showed an overall decline in breeding population of up to 43% for the period 1994 to 2001–02, and surveys of wintering birds in 2003–04 suggest a similarly large decline in core wintering areas. The Balearic Islands population has declined from 41 to 47 breeding pairs in 1993 to just 10 in 2003. In France, breeding populations have decreased in the northeast, but seem to be stable in southwest and central France and Corsica. Populations elsewhere are stable or undergoing increases. In Sweden, the species has increased from 30 to 50 pairs in the 1970s to 1,200 breeding pairs in 2003. In Switzerland, populations increased during the 1990s, and have stabilised. Red kites are decreasing in their strongholds of Spain, France and Germany, but are increasing in parts of northern Europe, such as Denmark, Sweden and the United Kingdom.
+
+
+=== United Kingdom ===
+
+In the United Kingdom, red kites were ubiquitous scavengers that lived on carrion and rubbish. Shakespeare's King Lear describes his daughter Goneril as a detested kite, and he wrote "when the kite builds, look to your lesser linen" in reference to them stealing washing hung out to dry in the nesting season. In the mid-15th century, King James II of Scotland decreed that they should be "killed wherever possible", but they remained protected in England and Wales for the next 100 years as they kept the streets free of carrion and rotting food. Under Tudor "vermin laws" many creatures were seen as competitors for the produce of the countryside and bounties were paid by the parish for their carcasses.By the 20th century, the breeding population was restricted to a handful of pairs in South Wales, but recently the Welsh population has been supplemented by re-introductions in England and Scotland. In 2004, from 375 occupied territories identified, at least 216 pairs were thought to have hatched eggs and 200 pairs reared at least 286 young. In 1989, six Swedish birds were released at a site in north Scotland and four Swedish and one Welsh bird in Buckinghamshire. Altogether, 93 birds of Swedish and Spanish origin were released at each of the sites. In the second stage of reintroduction in 1995 and 1996, further birds were brought from Germany to populate areas of Dumfries and Galloway. Between 2004 and 2006, 94 birds were brought from the Chilterns and introduced into the Derwent Valley in north East England. In Northern Ireland, 80 birds from wild stock in Wales were released between 2008 and 2010, and the first successful breeding was recorded in 2010. The reintroductions in the Chilterns Area of Outstanding Natural Beauty have been a success. Between 1989 and 1993, 90 birds were released there and by 2002, 139 pairs were breeding. They can commonly be seen taking advantage of thermals from the M40 motorway. Another successful reintroduction has been in Northamptonshire, which has become a stronghold for the red kite. Thirty Spanish birds were introduced into Rockingham Forest near Corby in 2000, and by 2010, the RSPB estimated that over 200 chicks had been reared from the initial release. So successful has the reintroduction been that 30 chicks have been transported from Rockingham Forest for release in Cumbria. From the Chilterns they have spread as far east as Essex and can be seen over Harlow.  To the west they have recently (2021) spread along the M4 as far as the Cotswold Edge overlooking the Severn near Bristol.
+A sighting of the first red kite in London for 150 years was reported in The Independent newspaper in January 2006 and in June of that year, the UK-based Northern Kites Project reported that kites had bred in the Derwent Valley in and around Rowlands Gill, Tyne and Wear for the first time since the re-introduction.In 1999, the red kite was named 'Bird of the Century' by the British Trust for Ornithology. According to the Welsh Kite Trust, it has been voted "Wales's favourite bird".In June 2010, the Forestry Commission North West England announced a three-year project to release 90 red kites in Grizedale Forest, Cumbria under a special licence issued by Natural England. The Grizedale programme was the ninth reintroduction of red kites into different regions of the UK and the final re-introduction phase in England.The stated aims of the Grizedale project were:
+
+To establish a viable population of red kites in Grizedale, South Cumbria by 2015.
+To increase the rate of red kite expansion into North West England and link up with existing populations in Wales, Yorkshire, North East England and South West Scotland and so increase the chances of a continuous geographical range.
+To develop community involvement and create educational opportunities arising from the project.As of July 2011, non-breeding birds are regularly seen in all parts of Britain, and the number of breeding pairs is too large for the RSPB to continue to survey them on an annual basis.
+
+
+=== Ireland ===
+Red kites were extinct in Ireland by the middle nineteenth century, due to persecution, poisoning and woodland clearance. In May 2007, Minister for the Environment, Heritage and Local Government Dick Roche announced an agreement to bring at least 100 birds from Wales to restock the population as part of a 5-year programme in the Wicklow Mountains, similar to the earlier golden eagle reintroduction programme. On 19 July 2007, the first thirty red kites were released in County Wicklow. On 22 May 2010, 2 newly hatched red kite chicks were discovered in the Wicklow mountains, bringing the number of chicks hatched since reintroduction to 7.
+
+
+=== Sweden ===
+Sweden is one location where the red kite seems to be increasing, with around 2,000 pairs in 2009, some of which are overwintering and some flying south to the Mediterranean for the winter. They return around March–April. The red kite is the landscape bird of Scania, and the coat of arms of the municipality of Tomelilla. The kite is often seen along the roadsides and roaming the open colourful wheat and rapeseed fields of Scania.
+
+
+=== Populations and trends by country ===
+
+The following figures (mostly estimates) have been collated from various sources. They cover most of the countries in which red kites are believed to have bred.
+
+
+== Observation ==
+
+One of the best places to see the red kite in Scandinavia is Scania in southern Sweden. It may be observed in one of its breeding locations such as the Kullaberg Nature Preserve near Mölle. In Switzerland, they are a common sight in all rural areas, excluding the Alps and its foothills.
+Some of the best places to see them in the United Kingdom are Gigrin Farm near Rhayader, mid Wales, where hundreds are fed by the local farmer as a tourist attraction, a Red Kite Feeding Station at Llanddeusant in the Brecon Beacons, visited daily by over 50 birds, and the Bwlch Nant yr Arian forest visitor centre in Ceredigion where the rare leucistic variant can be seen. In the UK, the Oxfordshire part of the Chilterns has many red kites, especially near Henley-on-Thames and Watlington, where they were introduced on John Paul Getty's estate. Red Kites are also becoming common in Buckinghamshire, often being seen near Stokenchurch, where a population was released in the 1990s, and Flackwell Heath near High Wycombe. They can also be seen around Harewood near Leeds where they were re-introduced in 1999. In Ireland they can be best observed at Redcross, near Avoca, County Wicklow.

+The wrinkled hornbill or Sunda wrinkled hornbill (Rhabdotorrhinus corrugatus) is a medium-large hornbill which is found in forest in the Thai-Malay Peninsula, Sumatra and Borneo.
+
+The wrinkled hornbill is around 70 cm long, and has a very large bill that is fused to the skull. It has mainly black plumage, a blue eye-ring, and a broadly white or rufous-tipped tail. The male and female have different head and bill patterns. Males have bright yellow feathers on the auriculars, cheeks, throat, neck-sides and chest, but these areas are black in the female, except for the blue throat. The bill of the male is yellow with a red base and casque, and a brownish basal half of the lower mandible. The bill and casque of the female is almost entirely yellow.
+This is a forest species and eats mainly fruit, such as figs, although it will also eat small animals such as frogs and insects. Wrinkled hornbills do not drink, but get the water they need from their food. Their call is a harsh "Kak-kak", or a deep "Row-wow" which can be heard for miles.
+These birds are monogamous and remain in a pair for life. They use holes found in trees for nests, and the female will plaster over the entrance with mud and droppings, leaving a nesting mother and her chicks only a small hole, too small for them to exit. They are fed exclusively by the male, who regurgitates food for them. After several months, when the chicks are ready, the female will break out of her nest. 
+Wrinkled hornbills were first bred in captivity in 1988. Heavy deforestation in their forest habitat has led them to be uplisted from near threatened to endangered on the IUCN Red List in 2018.

+The greater rhea (Rhea americana) is a species of flightless bird native to eastern South America. Other names for the greater rhea include the grey, common, or American rhea; ema (Portuguese); or ñandú (Guaraní and Spanish). One of two species in the genus Rhea, in the family Rheidae, the greater rhea is native to Brazil, Bolivia, Argentina, Paraguay and Uruguay. It inhabits a variety of open areas, such as grasslands, savanna or grassy wetlands. Weighing 20–27 kilograms (44–60 lb), the greater rhea is the largest bird in South America and the largest native, extant bird anywhere in the Americas. In the wild, the greater rhea has a life expectancy of 10.5 years. It is also notable for its reproductive habits, and for the fact that a population has established itself in Northern Germany in recent years. The species is listed as Near Threatened by the IUCN.
+
+
+== Taxonomy and systematics ==
+The greater rhea derives its scientific name from Rhea, a Greek goddess, and the Latinized form of America. It was originally described by Carl Linnaeus in his 18th-century work, Systema Naturae under the name Struthio camelus americanus. He identified specimens from Sergipe, and Rio Grande do Norte, Brazil, in 1758. They are from the family Rheidae, and the order Rheiformes. They are closely related to other ratites such as emus, ostriches, cassowaries, and kiwi, along with the extinct forms: moa and elephant birds.
+
+
+=== Subspecies ===
+There are five subspecies of the greater rhea; their ranges meet around the Tropic of Capricorn:
+R. a. americana campos of northern and eastern Brazil
+R. a. intermedia Uruguay and extreme southeastern Brazil (Rio Grande do Sul state)
+R. a. nobilis eastern Paraguay, east of Rio Paraguay
+R. a. araneipes  chaco of Paraguay and Bolivia and the Mato Grosso state of Brazil
+R. a. albescens plains of Argentina south to the Rio Negro provinceMain subspecific differences are the extent of the black coloring of the throat and the height. However, subspecies of the greater rhea differ so little across their range that, without knowledge of the place of origin, it is essentially impossible to identify captive birds by subspecies.
+
+
+== Description ==
+
+The adults have an average weight of 20–27 kg (44–60 lb) and often measure 127 to 140 cm (50 to 55 in) long from beak to tail; they usually stand about 1.5 m (4 ft 11 in) tall, with a typical range of 1.4 to 1.7 m (4 ft 7 in to 5 ft 7 in), to the top of the head. The males are generally bigger than the females. Despite the delineation of this species as the "greater rhea" versus the lesser rhea, some data on body masses indicates that both species average about 23 kg (51 lb) in weight, but even at mass parity that greater species appears larger and is taller due to its longer legs and neck, whereas the lesser rhea is more compact and more so resembles an outsized, long-necked turkey in build.  Elsewhere, the lesser rhea has been cited with a lower average weight of 16 kg (35 lb). In some areas, male greater rheas weights of up to 35 kg (77 lb) are not uncommon and even females of up to 30 kg (66 lb) have been weighed, both weights higher than the maximum known mass for the lesser rhea. Large males can weigh up to 40 kg (88 lb), stand nearly 1.83 m (6.0 ft) tall and measure over 150 cm (59 in) long, although this is uncommon.The head and bill are fairly small, the latter measuring 8–10.4 cm (3.1–4.1 in) in length. The legs are long, with the tarsus measuring between 33.5 and 37 cm (13.2 and 14.6 in), and strong and have 22 horizontal plates on the front of the tarsus. They have three toes, and the hind toe is absent. The wings of the American rhea are rather long; the birds use them during running to maintain balance during tight turns, and also during courtship displays.
+Greater rheas have a fluffy, tattered-looking plumage, that is gray or brown, with high individual variation, The head, neck, rump, and thighs are feathered. In general, males are darker than females. Even in the wild—particularly in Argentina—leucistic individuals (with white body plumage and blue eyes) as well as albinos occur. Hatchling greater rheas are grey with dark lengthwise stripes.
+
+
+== Distribution and habitat ==
+The greater rhea is native to Argentina, Bolivia, Brazil, Paraguay, and Uruguay. There are also feral populations of the greater rhea in Germany. This species inhabits grassland dominated by satintail (Imperata) and bahiagrass (Paspalum) species, as well as savanna, scrub forest, chaparral, and even desert and palustrine lands, though it prefers areas with at least some tall vegetation. It is absent from the humid tropical forests of the Mata Atlântica and planalto uplands along the coast of Brazil and extends south to 40° latitude. They prefer lower elevations and seldom go above 1,200 metres (3,900 ft). During the breeding season (spring and summer), it stays near water.
+A small non-indigenous population of the greater rhea established itself in Germany. One male and five females escaped from a farm in Groß Grönau, Schleswig-Holstein, in August 2000. These birds survived the winter and succeeded in breeding in a habitat sufficiently similar to their native South American range. They eventually crossed the Wakenitz river and settled in Nordwestmecklenburg in the area around and particularly to the north of Thandorf village. A biosurvey conducted in late 2012 found the population had grown to more than 100 and was settling in permanently. In early 2017 the population reached about 220 birds. As local farmers suffered harvest losses due to the birds, some farmers were granted an allowance to destroy the eggs of the birds to stop the population from growing further. At the end of 2017 a population of about 250 birds was estimated. They are regarded as "domestic" and thus protected from hunting. In the autumn of 2018, the German population grew to 566 individuals, and hunting of the birds was allowed; additionally, the population was reduced by destroying eggs during breeding season.

+
+== Behavior and ecology ==
+
+
+=== Individual and flock behavior ===
+The greater rhea is a silent bird except during mating season, when they make low booming noises, and as chicks, when they give a mournful whistle. During the non-breeding season they will form flocks of between 10 and 100 birds. When in flocks, they tend to be less vigilant, but the males can get aggressive towards other males. When chased they will flee in a zigzag pattern, alternately raising one wing then the other. These flocks break up in the winter in time for breeding season.
+
+
+=== Feeding and diet ===
+
+The rhea's diet mainly consists of broad-leaved foliage, particularly seed and fruit when in season, but also insects, scorpions, fish, small rodents, reptiles, and small birds. 
+Favorite food plants include native and introduced species from all sorts of dicot families, such as Amaranthaceae, Asteraceae, Bignoniaceae, Brassicaceae, Fabaceae, Lamiaceae, Myrtaceae or Solanaceae. Magnoliidae fruit, for example of Duguetia furfuracea (Annonaceae) or avocados (Persea americana, Lauraceae) can be seasonally important.They do not usually eat cereal grains, or monocots in general. However, the leaves of particular grass species like Brachiaria brizantha can be eaten in large quantities, and broad-leaved plants (e.g. the sarsaparilla Smilax brasiliensis) have also been recorded as foodplants. Even tough and spiny vegetable matter like tubers or thistles is eaten with relish.Like many birds which feed on tough plant matter, the greater rhea swallows pebbles which help grind down the food for easy digestion. It is much attracted to sparkling objects and sometimes accidentally swallows metallic or glossy objects. Rheas are also coprophagous and occasionally consume fresh fecal matter of other rheas.
+
+In fields and plantations of plants they do not like to eat, e.g., cereals or eucalyptus, the greater rhea can be a species quite beneficial to farmers. It will eat any large invertebrate it can catch; its food includes locusts and grasshoppers, true bugs, cockroaches, and other pest insects. Juveniles eat more animal matter than adults. In mixed cerrado and agricultural land in Minas Gerais (Brazil), R. a. americana was noted to be particularly fond of beetles. It is not clear whether this applies to the species in general but for example in pampas habitat, beetle consumption is probably lower simply due to availability while Orthoptera might be more important.The greater rhea is able to eat Hymenoptera in quantity. These insects contain among them many who can give painful stings, though the birds do not seem to mind. Sometimes, greater rheas will gather at carrion to feed on flies; they are also known to eat dead or dying fish in the dry season, but as vertebrate prey in general not in large quantities.
+
+
+=== Reproduction ===
+
+After the large flocks break up in the winter, they form into three loose groups:
+single males,
+flocks of between two and fifteen females, and
+a large flock of yearlings.As winter approaches, males become more aggressive towards each other. Then they start courting females by calling and raising the front of their body up while keeping their neck straight and ruffling their plumage. They will raise their wings and may run some distance like this, sometime flapping their wings methodically. After doing this and attracting females, they will continue calling at a specific female, and will start to either walk alongside her or in front of her while spreading his wings and lowering his head. As the display continues, he will get more intense and animated and start waving his neck around and in figure eights. Once he has attracted a first mate he will copulate with her and then lead her to his nest.When it is time for the eggs to be laid, the male will typically be on the nest already and will act aggressive when approached by the female, covering his nest with his wings. He will gradually relax and allow her to crouch and lay the egg at the edge of the nest. The male will roll the egg into his nest.Males are simultaneously polygynous, females are serially polyandrous. In practice, this means that the females move around during breeding season, mating with a male and depositing their eggs with the male before leaving him and mating with another male. Males on the other hand are sedentary, attending the nests and taking care of incubation and the hatchlings all on their own. Recent evidence has shown that some males will utilize subordinate males to help incubate and protect the eggs. If this happens, the dominant male will find a second harem and start the process over again. The nests are thus collectively used by several females and can contain as many as 80 eggs laid by a dozen females; each individual female's clutch numbers some 5–10 eggs. However, the average clutch size is 26 eggs laid by 7 different females.Rhea eggs measure about 130 mm × 90 mm (5.1 in × 3.5 in) and weigh 600 g (21 oz) on average; they are thus less than half the size of an ostrich egg. Their shell is greenish-yellow when fresh but soon fades to dull cream when exposed to light. The nest is a simple shallow and wide scrape in a hidden location; males will drag sticks, grass, and leaves in the area surrounding the nest so it resembles a firebreak as wide as their neck can reach. The incubation period is 29–43 days. All the eggs hatch within 36 hours of each other even though the eggs in one nest were laid perhaps as much as two weeks apart. As it seems, when the first young are ready to hatch they start a call resembling a pop-bottle rocket or even fireworks, even while still inside the egg, thus the hatching time is coordinated. Greater rheas are half-grown about three months after hatching, and sexually mature by their 14th month.
+
+
+=== Predators ===
+The natural predators of adult greater rheas are limited to the cougar (Puma concolor), which are found in most areas inhabited by greater rheas and are certain to be their leading predator, and the jaguar (Panthera onca), which are found with greater rheas and opportunistically hunt them in the Paraguayan chaco, central Bolivia and the Brazilian cerrado. Feral dogs are known to kill younger birds, and the crested caracara (Caracara plancus) is suspected to prey on hatchlings. Armadillos sometimes feed on greater rhea eggs; nests have been found which had been undermined by a six-banded armadillo (Euphractus sexcinctus) or a big hairy armadillo (Chaetophractus villosus) and the rhea eggs were broken apart. Predation on young rheas has also been reportedly committed by greater grisons (Galictis vittata).Captive-bred greater rheas exhibit significant ecological naïvete. This fearlessness renders them highly vulnerable to predators if the birds are released into the wild in reintroduction projects. Classical conditioning of greater rhea juveniles against predator models can prevent this to some degree, but the personality type of the birds – whether they are bold or shy – influences the success of such training. In 2006, a protocol was established for training greater rheas to avoid would-be predators, and for identifying the most cautious animals for release.
+
+
+== Status and conservation ==
+
+The greater rhea is considered a Near Threatened species according to the IUCN, and they have a decreasing range of about 6,540,000 square kilometres (2,530,000 sq mi). The species is believed to be declining due to increased hunting and the conversion of central South American grasslands to farmland and ranchland. The populations of Argentina and Uruguay are most seriously affected by the decline.Farmers sometimes consider the greater rhea pests, because they will eat broad-leaved crop plants, such as cabbage, chard and bok choy. Where they occur as pests, farmers tend to hunt and kill greater rheas. The burning of crops in South America has also contributed to their decline.International trade in wild-caught greater rheas is restricted as per CITES Appendix II.The rheas in Germany are legally protected in a similar way to native species. In its new home, the greater rhea is considered generally beneficial as its browsing helps maintain the habitat diversity of the sparsely populated grasslands bordering the Schaalsee biosphere reserve. They are however considered as a threat to local farmers and described as an invasive species since 2015 according to the NHBS. German authorities have issued 'alternatives' to culling the birds which still sparks controversy.
+
+
+== Relationship with humans ==
+
+Ancient humans in the Patagonia region used to hunt greater rhea, and stencils of greater rhea feet dating back to the early holocene can be found at rock art sites such as Cueva de las Manos.This species is farmed in North America and Europe similar to the emu and ostrich. The main products are meat and eggs, but rhea oil is used for cosmetics and soaps and rhea leather is also traded in quantity. Male greater rheas are very territorial during the breeding season. The infant chicks have high mortality in typical confinement farming situations, but under optimum free-range conditions chicks will reach adult size by their fifth month.

+The Indian rhinoceros (Rhinoceros unicornis), also called the Indian rhino, greater one-horned rhinoceros or great Indian rhinoceros, is a rhinoceros species native to the Indian subcontinent. It is listed as Vulnerable on the IUCN Red List, as populations are fragmented and restricted to less than 20,000 km2 (7,700 sq mi). Moreover, the extent and quality of the rhino's most important habitat, the alluvial Terai-Duar savanna and grasslands and riverine forest, is considered to be in decline due to human and livestock encroachment. As of August 2018, the global population was estimated to comprise 3,588 individuals, including 2,939 individuals in India and 649 in Nepal. Kaziranga National Park alone had an estimated population of 2,048 rhinos in 2009. Pobitora Wildlife Sanctuary in Assam has the highest density of Indian rhinos in the world with 84 individuals in an area of 38.80 km2 (14.98 sq mi) in 2009.Indian rhinos once ranged throughout the entire stretch of the Indo-Gangetic Plain, but excessive hunting and agricultural development reduced its range drastically to 11 sites in northern India and southern Nepal. In the early 1990s, between 1,870 and 1,895 Indian rhinos were estimated to have been alive. Since then, numbers have increased due to conservation measures taken by the government. However, poaching remains a continuous threat, as more than 150 Indian rhinos were killed in Assam by poachers between 2000 and 2006.Nearly 85% of the global Indian rhinoceros population is concentrated in Assam, where Kaziranga National Park contains 70% of rhino population.
+
+
+== Etymology ==
+The generic name Rhinoceros is a combination of the ancient Greek words ῥίς (ris) meaning "nose" and κέρας (keras) meaning "horn of an animal". The Latin word ūnicornis means "one-horned".
+
+
+== Taxonomy ==
+Rhinoceros unicornis was the scientific name used by Carl Linnaeus in 1758 who described a rhinoceros with one horn. As type locality, he indicated Africa and India.The Indian rhinoceros is monotypic. Several specimens were described since the end of the 18th century under different scientific names, which are all considered synonyms of Rhinoceros unicornis today:
+R. indicus by Cuvier, 1817
+R. asiaticus by Blumenbach, 1830
+R. stenocephalus by Gray, 1867
+R. jamrachi by Sclater, 1876
+R. bengalensis by Kourist, 1970
+
+
+== Evolution ==
+
+Ancestral rhinoceroses first diverged from other perissodactyls in the Early Eocene. Mitochondrial DNA comparison suggests the ancestors of modern rhinos split from the ancestors of Equidae around 50 million years ago. The extant family, the Rhinocerotidae, first appeared in the Late Eocene in Eurasia, and the ancestors of the extant rhino species dispersed from Asia beginning in the Miocene.Fossils of R. unicornis appear in the Middle Pleistocene. In the Pleistocene, the genus Rhinoceros ranged throughout South and Southeast Asia, with specimens located on Sri Lanka. Into the Holocene, some rhinoceros lived as far west as Gujarat and Pakistan until as recently as 3,200 years ago.The Indian and Javan rhinoceroses, the only members of the genus Rhinoceros, first appear in the fossil record in Asia during the Early Pleistocene. The Indian rhinoceros is known from Early Pleistocene localities in Java, South China, India and Pakistan. Molecular estimates suggest the species may have diverged much earlier, around 11.7 million years ago. Although belonging to the type genus, the Indian and Javan rhinoceroses are not believed to be closely related to other rhino species. Different studies have hypothesised that they may be closely related to the extinct Gaindatherium or Punjabitherium. A detailed cladistic analysis of the Rhinocerotidae placed Rhinoceros and the extinct Punjabitherium in a clade with Dicerorhinus, the Sumatran rhinoceros. Other studies have suggested the Sumatran rhinoceros is more closely related to the two African species. The Sumatran rhino may have diverged from the other Asian rhinos as long as 15 million years ago.
+
+
+== Characteristics ==
+
+Indian rhinos have a thick grey-brown skin with pinkish skin folds and one horn on their snout. Their upper legs and shoulders are covered in wart-like bumps. They have very little body hair, aside from eyelashes, ear fringes and tail brush. Bulls have huge neck folds. The skull is heavy with a basal length above 60 cm (24 in) and an occiput above 19 cm (7.5 in). The nasal horn is slightly back-curved with a base of about 18.5 cm (7.3 in) by 12 cm (4.7 in) that rapidly narrows until a smooth, even stem part begins about 55 mm (2.2 in) above base. In captive animals, the horn is frequently worn down to a thick knob.The Indian rhino's single horn is present in both bulls and cows, but not on newborn calves. The horn is pure keratin, like human fingernails, and starts to show after about six years. In most adults, the horn reaches a length of about 25 cm (9.8 in), but has been recorded up to 36 cm (14 in) in length and 3.051 kg (6.73 lb) in weight.Among terrestrial land mammals native to Asia, Indian rhinos are second in size only to the Asian elephant. They are also the second-largest living rhinoceros, behind only the white rhinoceros. Bulls have a head and body length of 368–380 cm (12.07–12.47 ft) with a shoulder height of 170–186 cm (5.58–6.10 ft), while cows have a head and body length of 310–340 cm (10.2–11.2 ft) and a shoulder height of 148–173 cm (4.86–5.68 ft). The bull, averaging about 2,200 kg (4,850 lb) is heavier than the cow, at an average of about 1,600 kg (3,530 lb).The rich presence of blood vessels underneath the tissues in folds gives them the pinkish colour. The folds in the skin increase the surface area and help in regulating the body temperature. The thick skin does not protect against bloodsucking Tabanus flies, leeches and ticks.The largest individuals reportedly weighed up to 4,000 kg (8,820 lb).
+
+
+== Distribution and habitat ==
+
+Indian rhinos once ranged across the entire northern part of the Indian Subcontinent, along the Indus, Ganges and Brahmaputra River basins, from Pakistan to the Indian-Myanmar border, including Bangladesh and the southern parts of Nepal and Bhutan. They may have also occurred in Myanmar, southern China and Indochina. They inhabit the alluvial grasslands of the Terai and the Brahmaputra basin. As a result of habitat destruction and climatic changes its range has gradually been reduced so that by the 19th century, it only survived in the Terai grasslands of southern Nepal, northern Uttar Pradesh, northern Bihar, northern West Bengal, and in the Brahmaputra Valley of Assam.The species was present in northern Bihar and Oudh at least until 1770 as indicated in maps produced by Colonel Gentil. On the former abundance of the species, Thomas C. Jerdon wrote in 1867:
+This huge rhinoceros is found in the Terai at the foot of the Himalayas, from Bhutan to Nepal. It is more common in the eastern portion of the Terai than the west, and is most abundant in Assam and the Bhutan Dooars. I have heard from sportsmen of its occurrence as far west as Rohilcund, but it is certainly rare there now, and indeed along the greater part of the Nepal Terai; ... Jelpigoree, a small military station near the Teesta River, was a favourite locality whence to hunt the Rhinoceros and it was from that station Captain Fortescue ... got his skulls, which were ... the first that Mr. Blyth had seen of this species, ...
+Today, its range has further shrunk to a few pockets in southern Nepal, northern West Bengal, and the Brahmaputra Valley. Its habitat is surrounded by human-dominated landscapes, so that in many areas, it occurs in cultivated areas, pastures, and secondary forests. In the 1980s, Indian rhinos were frequently seen in the narrow plain area of Manas River and Royal Manas National Park in Bhutan.
+
+
+=== Populations ===
+
+In 2006, the total Indian rhinoceros population was estimated to comprise 2,577 individuals, of which 2,165 lived in India:
+23 individuals in Uttar Pradesh, including 21 in Dudhwa National Park and 2 in Katarniaghat Wildlife Sanctuary
+135 individuals in West Bengal, including 108 in Jaldapara National Park and 27 in Gorumara National Park
+2,007 individuals in Assam, including 1,855 in Kaziranga National Park, 81 in Pobitora Wildlife Sanctuary, 68 in Orang National Park and 3 in Manas National Park.By 2014, the population in Assam increased to 2,544 Indian rhinos, an increase of 27% since 2006, although more than 150 individuals were killed by poachers during these years.
+The population in Kaziranga National Park was estimated at 2,048 individuals in 2009. By 2009, the population in Pobitora Wildlife Sanctuary had increased to 84 individuals in an area of 38.80 km2 (14.98 sq mi).In 2015, Nepal had 645 Indian rhinos living in Parsa National Park, Chitwan National Park, Bardia National Park, Shuklaphanta Wildlife Reserve and respective buffer zones in the Terai Arc Landscape as recorded in a survey conducted from 11 April to 2 May 2015. The survey showed that the population of rhinos in Nepal from 2011 to 2015 increased 21% or 111 individuals.The Indian rhino population, which once numbered as low as 100 individuals in the early 1900s, has increased to more than 3,700 in year 2021 as per The International Rhino Foundation (IRF) signature 2021 report, State of the Rhino.
+
+
+== Ecology and behaviour ==
+
+Bulls are usually solitary. Groups consist of cows with calves, or of up to six subadults. Such groups congregate at wallows and grazing areas. They are foremost active in early mornings, late afternoons and at night, but rest during hot days.They bathe regularly. The folds in their skin trap water and hold it even when they exit wallows.They are excellent swimmers and can run at speeds of up to 55 km/h (34 mph) for short periods. They have excellent senses of hearing and smell, but relatively poor eyesight. Over 10 distinct vocalisations have been recorded. Males have home ranges of around 2 to 8 km2 (0.77 to 3.09 sq mi) that overlap each other. Dominant males tolerate other males passing through their territories except when they are in mating season, when dangerous fights break out.
+Indian rhinos have few natural enemies, except for tigers, which sometimes kill unguarded calves, but adult rhinos are less vulnerable due to their size. Mynahs and egrets both eat invertebrates from the rhino's skin and around its feet. Tabanus flies, a type of horse-fly, are known to bite rhinos. The rhinos are also vulnerable to diseases spread by parasites such as leeches, ticks, and nematodes. Anthrax and the blood-disease sepsis are known to occur.
+In March 2017, a group of four tigers consisting of an adult male, tigress and two cubs killed a 20-year-old male Indian rhinoceros in Dudhwa Tiger Reserve.
+
+
+=== Diet ===
+Indian rhinos are grazers. Their diet consists almost entirely of grasses, but they also eat leaves, branches of shrubs and trees, fruits, and submerged and floating aquatic plants. 
+They feed in the mornings and evenings. They use their semi-prehensile lips to grasp grass stems, bend the stem down, bite off the top, and then eat the grass. They tackle very tall grasses or saplings by walking over the plant, with legs on both sides and using the weight of their bodies to push the end of the plant down to the level of the mouth. Mothers also use this technique to make food edible for their calves. They drink for a minute or two at a time, often imbibing water filled with rhinoceros urine.
+
+
+=== Social life ===
+
+Indian rhinos form a variety of social groupings. Bulls are generally solitary, except for mating and fighting. Cows are largely solitary when they are without calves. Mothers will stay close to their calves for up to four years after their birth, sometimes allowing an older calf to continue to accompany her once a newborn calf arrives. Subadult bulls and cows form consistent groupings, as well. Groups of two or three young bulls will often form on the edge of the home ranges of dominant bulls, presumably for protection in numbers. Young cows are slightly less social than the bulls. Indian rhinos also form short-term groupings, particularly at forest wallows during the monsoon season and in grasslands during March and April. Groups of up to 10 rhinos may gather in wallows—typically a dominant male with females and calves, but no subadult males.Indian rhinos make a wide variety of vocalisations. At least ten distinct vocalisations have been identified: snorting, honking, bleating, roaring, squeak-panting, moo-grunting, shrieking, groaning, rumbling and humphing. In addition to noises, the Indian rhino uses olfactory communication. Adult bulls urinate backwards, as far as 3–4 metres (9.8–13.1 ft) behind them, often in response to being disturbed by observers. Like all rhinos, the Indian rhinoceros often defecates near other large dung piles. The Indian rhino has pedal scent glands which are used to mark their presence at these rhino latrines. Bulls have been observed walking with their heads to the ground as if sniffing, presumably following the scent of cows.In aggregations, Indian rhinos are often friendly. They will often greet each other by waving or bobbing their heads, mounting flanks, nuzzling noses, or licking. Indian rhinos will playfully spar, run around, and play with twigs in their mouths. Adult bulls are the primary instigators in fights. Fights between dominant bulls are the most common cause of rhino mortality, and bulls are also very aggressive toward cows during courtship. Bulls will chase cows over long distances and even attack them face-to-face. Unlike African rhinos, Indian rhinos fight with their incisors, rather than their horn.
+
+
+=== Reproduction ===
+
+Captive bulls breed at five years of age, but wild bulls attain dominance much later when they are larger. In one five-year field study, only one Indian rhino estimated to be younger than 15 years mated successfully. Captive cows breed as young as four years of age, but in the wild, they usually start breeding only when six years old, which likely indicates they need to be large enough to avoid being killed by aggressive bulls. Their gestation period is around 15.7 months, and birth interval ranges from 34 to 51 months.In captivity, four Indian rhinos are known to have lived over 40 years, the oldest living to be 47.
+
+
+== Threats ==
+
+
+=== Habitat degradation and floods ===
+Habitat degradation caused by human activities and climate change as well as the resulting increase in the floods has caused large death of Indian rhinos and has limited their ranging areas which is shrinking.
+Serious declines in quality of habitat have occurred in some areas, due to:
+
+severe invasion by alien plants into grasslands affecting some populations;
+demonstrated reductions in the extent of grasslands and wetland habitats due to woodland encroachment and silting up of beels (swampy wetlands);
+grazing by domestic livestock.
+
+
+=== Lack of site diversity ===
+The Indian rhino species is inherently at risk because over 70% of its population occurs at a single site, Kaziranga National Park. Any catastrophic event such as disease, civil disorder, poaching, or habitat loss would have a devastating impact on the Indian rhino's status. However, small population of rhinos may be prone to inbreeding depression. Expansion of other protective areas and introduction of rhinos in more areas is needed.
+
+
+=== Poaching ===
+
+Sport hunting became common in the late 19th and early 20th centuries and was the main cause for the decline of Indian rhinoceros populations. Indian rhinos were hunted relentlessly and persistently. Reports from the mid-19th century claim that some British military officers shot more than 200 rhinos in Assam alone. By 1908, the population in Kaziranga National Park had decreased to around 12 individuals. In the early 1900s, the Indian rhinoceros was almost extinct. At present, poaching for the use of horn in traditional Chinese Medicine is one of the main threats that has led to decreases in several important populations. Poaching for the Indian rhino's horn became the single most important reason for the decline of the Indian rhinoceros after conservation measures were put in place from the beginning of the 20th century, when legal hunting ended. From 1980 to 1993, 692 rhinos were poached in India, including 41 rhinos in India's Laokhowa Wildlife Sanctuary in 1983, almost the entire population of the sanctuary. By the mid-1990s, the Indian rhinoceros had been extirpated in this sanctuary. Between 2000 and 2006, more than 150 rhinos were poached in Assam. Almost 100 rhinos were poached in India between 2013 and 2018.
+
+In 1950, in Nepal the Chitwan’s forest and grasslands extended over more than 2,600 km2 (1,000 sq mi) and were home to about 800 rhinos. When poor farmers from the mid-hills moved to the Chitwan Valley in search of arable land, the area was subsequently opened for settlement, and poaching of wildlife became rampant. The Chitwan population has repeatedly been jeopardised by poaching; in 2002 alone, poachers killed 37 animals to saw off and sell their valuable horns.Six methods of killing Indian rhinos have been recorded:
+Shooting is by far the most common method used; rhino horn traders hire sharpshooters and often supply them with rifles and ammunition.
+Trapping in a pit depends largely on the terrain and availability of grass to cover it; pits are dug out in such a way that a fallen animal has little room to manoeuvre with its head slightly above the pit, so that it is easy to saw off the horn.
+Electrocution is used where high voltage powerlines pass through or near a protected area, to which poachers hook a long, insulated rod connected to a wire, which is suspended above a rhino path.
+Poisoning by smearing zinc phosphide rat poison or pesticides on salt licks frequented by rhinos is sometimes used.
+Spearing has only been recorded in Chitwan National Park.
+A noose, which cuts through the rhino's skin, kills it by strangulation.
+
+
+== Conservation ==
+
+Globally, Rhinoceros unicornis has been listed in CITES Appendix I since 1975. The Indian and Nepalese governments have taken major steps towards Indian rhinoceros conservation, especially with the help of the World Wide Fund for Nature (WWF) and other non-governmental organisations. In 1910, all rhino hunting in India became prohibited.In 1957, the country's first conservation law ensured the protection of rhinos and their habitat. In 1959, Edward Pritchard Gee undertook a survey of the Chitwan Valley, and recommended the creation of a protected area north of the Rapti River and of a wildlife sanctuary south of the river for a trial period of 10 years. After his subsequent survey of Chitwan in 1963, he recommended extension of the sanctuary to the south. By the end of the 1960s, only 95 rhinos remained in the Chitwan Valley. The dramatic decline of the rhino population and the extent of poaching prompted the government to institute the Gaida Gasti – a rhino reconnaissance patrol of 130 armed men and a network of guard posts all over Chitwan. To prevent the extinction of rhinos, the Chitwan National Park was gazetted in December 1970, with borders delineated the following year and established in 1973, initially encompassing an area of 544 km2 (210 sq mi). To ensure the survival of rhinos in case of epidemics, animals were translocated annually from Chitwan to Bardia National Park and Shuklaphanta National Park since 1986.
+The Indian rhinoceros population living in Chitwan and Parsa National Parks was estimated at 608 mature individuals in 2015.
+
+
+=== Reintroduction to new areas ===
+Indian rhinos have been reintroduced to the following new areas where they had previously inhabited but became extinct. These efforts have produced mixed results, mainly Due to lack of proper planning and management, sustained effort, adequate security of the introduced animals.
+In 1984, five Indian rhinos were relocated to Dudhwa National Park — four from the fields outside the Pobitora Wildlife Sanctuary and one from Goalpara. This has born results and the population has increased to 21 rhinos by 2006.In early 1980s, Laokhowa Wildlife Sanctuary in Assam had more than 70 Indian rhinos which were all killed by poachers. In 2016, two Indian rhinos, a mother and her daughter, were reintroduced to the sanctuary from Kaziranga National Park as part of the Indian Rhino Vision 2020 (IRV 2020) program, but both animals died within months due to natural causes.Indian rhinos were once found as far west as the Peshawar Valley during the reign of Mughal Emperor Babur, but are now extinct in Pakistan. After rhinos became "regionally extinct" in Pakistan, two rhinos from Nepal were introduced in 1983 to Lal Suhanra National Park, which have not bred so far.

+
+=== In captivity ===
+
+Indian rhinos were initially difficult to breed in captivity. In the second half of the 20th century, zoos became adept at breeding Indian rhinoceros. By 1983, nearly 40 babies had been born in captivity. As of 2012, 33 Indian rhinos were born at Switzerland's Zoo Basel alone, meaning that most captive animals are related to the Basel population. Due to the success of Zoo Basel's breeding program, the International Studbook for the species has been kept there since 1972. Since 1990, the Indian rhino European Endangered Species Programme is also being coordinated there, with the goal of maintaining genetic diversity in the global captive Indian rhinoceros population.The first recorded captive birth of an Indian rhinoceros was in Kathmandu in 1826, but another successful birth did not occur for nearly 100 years. In 1925, a rhino was born in Kolkata. No rhinoceros was successfully bred in Europe until 1956 when first European breeding took place when baby rhino Rudra was born in Zoo Basel on 14 September 1956.In June 2009, an Indian rhino was artificially inseminated using sperm collected four years previously and cryopreserved at the Cincinnati Zoo’s CryoBioBank before being thawed and used. She gave birth to a male calf in October 2010.In June 2014, the first "successful" live-birth from an artificially inseminated rhino took place at the Buffalo Zoo in New York. As in Cincinnati, cryopreserved sperm was used to produce the female calf, Monica.
+
+
+== Cultural significance ==
+The Indian rhinoceros is one of the motifs on the Pashupati seal and many terracotta figurines that were excavated at archaeological sites of the Indus Valley civilisation. A rhinoceros is the vahana of the Hindu goddess Dhavdi. There is a temple dedicated to Maa (Mother) Dhavdi in Dhrangadhra, Gujarat.The Rhinoceros Sutra is an early text in the Buddhist tradition, found in the Gandhāran Buddhist texts and the Pali Canon, as well as a version incorporated into the Sanskrit Mahavastu. It praises the solitary lifestyle and stoicism of the Indian rhinoceros and is associated with the eremitic lifestyle symbolized by the Pratyekabuddha.
+
+
+=== Europe ===
+
+In the 3rd century, Philip the Arab exhibited an Indian rhinoceros in Rome. In 1515, Manuel I of Portugal obtained an Indian rhinoceros as a gift, which he passed on to Pope Leo X, but which died on the way from Lisbon to Rome. Three artistic representations were prepared of this rhinoceros: Dürer's Rhinoceros, a woodcut by Hans Burgkmair dated to 1515, a drawing and a woodcut by Albrecht Dürer, also dated 1515. Dürer's Rhinoceros was sent as a present from the King of Portugal, Manuel I, to Pope Leo X in 1515, and this rhino died in a shipwreck off the coast of Italy in early 1516, and it was immortalised as Dürer's Rhinoceros in the woodcut. In 1577–1588, Abada was a female Indian rhinoceros kept by the Portuguese kings Sebastian I and Henry I from 1577 to 1580 and by Philip II of Spain from about 1580 to 1588. She was the first rhinoceros seen in Europe after Dürer's Rhinoceros. In about 1684, the first presumably Indian rhinoceros arrived in England. George Jeffreys, 1st Baron Jeffreys spread the rumour that his chief rival Francis North, 1st Baron Guilford had been seen riding on it.In 1741–1758, Clara the rhinoceros (c. 1738 – 14 April 1758) was a female Indian rhinoceros who became famous during 17 years of touring Europe in the mid-18th century. She arrived in Europe in Rotterdam in 1741, becoming the fifth living rhinoceros to be seen in Europe in modern times since Dürer's Rhinoceros in 1515. After tours through towns in the Dutch Republic, the Holy Roman Empire, Switzerland, the Polish–Lithuanian Commonwealth, France, the Kingdom of the Two Sicilies, the Papal States, Bohemia and Denmark, she died in Lambeth, England. In 1739, she was drawn and engraved by two English artists. It was then brought to Amsterdam, where Jan Wandelaar made two engravings that were published in 1747. In the subsequent years, the rhinoceros was exhibited in several European cities. In 1748, Johann Elias Ridinger made an etching of it in Augsburg, and Petrus Camper modelled it in clay in Leiden. In 1749, Georges-Louis Leclerc, Comte de Buffon drew it in Paris. In 1751, Pietro Longhi painted it in Venice.

+The wreathed hornbill (Rhyticeros undulatus) is an Old World tropical bird of the hornbill family Bucerotidae, also called bar-pouched wreathed hornbill due to its distinctive blue-black band on its lower throat sac. It is named after its characteristic long, curved bill that develops ridges, or wreaths, on the casque of the upper mandible in adults. Males are black with a rufous crown, a white upper breast and face, and a yellow featherless throat. Females are uniformly black with a blue throat and are slightly smaller than males.
+The wreathed hornbill ranges across the foothills and evergreen forests of Northeast India and Bhutan to Bangladesh, Southeast Asia and the Greater Sunda Islands.
+It is a frugivore and feeds mainly on large fruits, which it swallows whole leaving the seeds intact. This feeding behaviour plays an important ecological role for the long-distance seed dispersal in forest ecosystems.
+The wreathed hornbill is threatened by hunting, habitat fragmentation and deforestation. It has been listed as Vulnerable on the IUCN Red List since 2018, as the global population is estimated to decrease due to these threats.
+
+
+== Taxonomy ==
+English ornithologist George Shaw  first described the species in 1811 as Buceros undulatus, based on a zoological specimen collected in Java. It was placed in the genus Rhytidoceros by Daniel Giraud Elliot in 1882; in Rhyticeros by Allan Octavian Hume in 1878; and in Aceros by James L. Peters in 1931.The wreathed hornbill is a monotypic taxon and is widely recognized as a member of Rhyticeros, the genus of hornbills with low wreathed casques. 
+Analysis of the mitochondrial genomes of eight hornbill species revealed that the wreathed hornbill is closely related with Aceros and the Visayan hornbill (Penelopides panini).
+
+
+== Description ==
+
+The wreathed hornbill is black with black legs and feet, but has a pale yellow bill, bare reddish skin around the eyes, a black band around the gular skin and a white tail. The female's gular skin is blue, whereas the male's is bright yellow; his neck is white and his nape dark reddish passing into black. Sexual dimorphism in the colouration of plumage and inflatable gular skin is less pronounced in young wreathed hornbills, but becomes more apparent as both sexes mature.It is a medium-sized bird with a body length of 75 to 90 cm (30 to 35 in); adult males weigh from 1.68 to 3.65 kg (3.7 to 8.0 lb), and females weigh from 1.36 to 2.69 kg (3.0 to 5.9 lb).
+
+
+=== Bill morphology ===
+All members of the hornbill family have large, heavy bills with characteristic casques that distinguish them from other avian taxa. Hornbill casques contain foamy air-filled cavities surrounded by multiple layers of keratin tiles that act as an external shell.
+The extra weight of the casque is supported by the fusion of the first two vertebrae.The bill has distinctive serrated casques near the base of the upper mandible, which are particularly unique because of its ridges. As the birds mature, forward growth causes the foremost ridge to break off. It is hypothesized that specialized casque characteristics evolved due to multiple selection pressures, including its use for vocalization enhancement, physical pounding, mating displays, and as visual cues for age and social status.
+
+
+== Distribution and habitat ==
+
+The wreathed hornbill inhabits tropical evergreen forests in the region from southern Bhutan, Northeast India, Bangladesh and through mainland Southeast Asia to Indonesia, where it is restricted to Sumatra, Java, Borneo and a few smaller islands. It has been recorded up to an elevation of 2,560 m (8,400 ft).In Bhutan, two individuals were sighted in Sarpang district in spring 1986.In Northeast India, it inhabits unlogged primary forests and selectively logged forests in the foothills of the Eastern Himalayas from Nameri National Park in Assam to Namdapha National Park in Arunachal Pradesh.
+During the breeding season, it lives in lowland areas, but migrates to higher elevations in the non-breeding season.In Myanmar, 62 wreathed hornbills were sighted in the Mali River valley at elevations of 800–2,500 m (2,600–8,200 ft) in winter 1999.
+A flock of about 50 individuals was sighted in Hponkanrazi Wildlife Sanctuary in September 2004.
+
+
+== Behaviour and ecology ==
+
+The wreathed hornbill is a social bird and most active in the early mornings when foraging for fruits; 21 individuals studied in Pakke Tiger Reserve during the non-breeding season rested at midday and resumed activity in the early afternoons.It lives in larger flocks than other hornbill species and remains in groups during both breeding and non-breeding seasons.
+Flock size observed in Namdapha National Park ranged from a mean of 4.7 to 6.6 individuals with a density of 1.3 birds/km2 (3.4 birds/sq mi) in March and April to 68 birds/km2 (180 birds/sq mi) in December. In Arunachal Pradesh, the wreathed hornbill density is much lower in habitats where local people hunt, ranging from 2.9 to 9.02 birds/km2 (7.5 to 23.4 birds/sq mi).It travels long distances to forage for fruit, sometimes flying between islands, but it does not migrate.
+A male wreathed hornbill was fitted with a GPS tracking unit in Pakke Tiger Reserve during the breeding season; it moved a mean minimum daily distance of 24.8 km (15.4 mi) and dispersed seeds for up to 10.8 km (6.7 mi) from its nesting site.Home ranges of the wreathed hornbill and other hornbill species overlap in several range countries.
+
+
+=== Vocalizations ===
+The main call of the wreathed hornbill is a loud double yelp that has been described to sound like “coo-cuk” or “wuff-wurff”. This call is short and typically repeated in a sequence of three or more from a perching position or during flight. The second part of the call is higher pitched and louder than the first and can be heard from farther distances. When calling, the wreathed hornbill displays its brightly coloured throat sac by sharply thrusting its head backwards and upwards. This movement is thought to be a form of communication between individuals. It makes various other low-pitched, bisyllabic barking sounds.
+
+
+=== Diet and feeding ===
+The wreathed hornbill mainly feeds on large fruit with figs making up the majority of its diet. It consumes more drupaceous fruits than other hornbill species. It also occasionally eats small animals like insects, crabs, snails and reptiles, particularly during the breeding season. It forages in the forest canopy across its range, sometimes descending to eat small prey or to retrieve fallen fruit. Tropical fruit abundance can greatly vary by location and season, therefore the wreathed hornbill flies long distances to track areas with high fruit availability. As it moves across its range, it disperses the consumed seeds. The seed dispersal behaviour of the wreathed hornbill plays a critical role in maintaining tropical forest diversity.The feeding technique used by the wreathed hornbill is called ballistic food transport. It holds the large food item at the tip of its bill and throws its head back quickly, swallowing it whole. This behaviour is likely to reduce resource competition by exploiting fruit that is too large for smaller frugivores. Another advantage to ballistic food transport is that the fruit seeds are protected from damage when they are swallowed whole. The entire seed passes through the gastrointestinal tract and is excreted intact, increasing its chances of germination and forming a new plant.
+
+
+=== Reproduction ===
+
+The wreathed hornbill is a monogamous breeder that demonstrates biparental care. It nests in the cavities of large trees located in coastal forests, illegally logged areas, or among foothills up to an elevation of 2,560 m (8,400 ft). It searches for existing oval-shaped tree cavities for nesting because it cannot excavate its own. The nest height ranges from 18 to 28 m (59 to 92 ft) above ground. Females use droppings or mud to cover the nest hole to protect the clutch and fledglings from predators but leave a gap large enough for males to deliver food. They unload the mud when they need to leave the nest.The average clutch size of the wreathed hornbill is 1–3 eggs, which the female incubates and guards alone for 40 days. She raises only one of the chicks and remains with it in the nest until it fledges at the end of the nesting cycle, which lasts 111–137 days. Both parents remain with the juvenile for multiple months after it has left the nest.
+
+
+== Threats ==
+
+Major threats to wreathed hornbill populations include hunting, use of pesticides, illegal logging and habitat fragmentation. In Arunachal Pradesh, the local Mishmi and Adi people shoot 50–70 wreathed hornbills during the migratory season; they eat their meat, use their gizzards as medicine to cure stomach problems, their feathers to decorate their homes and their casques to adorn their headgear. Local people also hunt wreathed hornbills for sport and use their fat for medical purposes.The wreathed hornbill has been listed as a vulnerable species on the IUCN Red List since 2018, as these threats will likely lead to a decline of the global population in the near future.
+
+
+== Conservation ==
+The wreathed hornbill is internationally protected under CITES Appendix II and is a Class II national protected species in China.In Pakke Tiger Reserve, a community-based Hornbill Nest Adoption Program was initiated in collaboration with the Arunachal Pradesh Forest Department in 2011; local Nyishi people from nine villages worked as nest protectors and one youth as field coordinator; more than 90 urban citizens supported the project financially. In the breeding seasons of 2012 and 2013, the nest protectors located eight wreathed hornbill nests, of which two had fledgings.

+The crested partridge (Rollulus rouloul) also known as the crested wood partridge, roul-roul, red-crowned wood partridge, green wood quail or green wood partridge is a gamebird in the pheasant family Phasianidae of the order Galliformes, gallinaceous birds. It is the only member of the genus Rollulus.
+This small partridge is a resident breeder in lowland rainforests in south Burma, south Thailand, Malaysia, Sumatra and Borneo. Its nest is a ground scrape lined with leaves, which is concealed under a heap of leaf litter. Five or six white eggs are incubated for 18 days.
+Unusually for a galliform species, the young are fed bill-to-bill by both parents instead of pecking from the ground, and although precocial, they roost in the nest while small.
+The crested partridge is a rotund short-tailed bird, 25 cm (9.8 in) in length, with the male marginally larger than the female. Both sexes have a scarlet patch of bare skin around the eye and red legs without a spur or hind toe.
+The male is metallic green above with glossy dark blue underparts and a brownish wing panel. The head is adorned with a tall red crest, a white forehead spot and black frontal bristles. The female has pea-green body plumage apart from the brown wing coverts. She has a slate-grey head with the bristles but no spot or crest. The bill is all-dark. Young birds are duller versions of the adult of the same sex. The song is a mournful whistled si-ul.
+The crested partridge is usually seen singly or in pairs as it uses its feet to probe the forest floor for fruit, seeds and invertebrates. When disturbed, it prefers to run but if necessary it flies a short distance on its rounded wings.
+There is some concern about the effect of habitat destruction on this bird, especially with regard to logging. However, it seems to be somewhat more adaptable than other southeast Asian pheasants. The crested wood partridge is evaluated as Near Threatened on the IUCN Red List of Threatened Species. It is listed on Appendix III of CITES.

+Eld's deer (Rucervus eldii or Panolia eldii), also known as the thamin or brow-antlered deer, is an endangered species of deer endemic to South Asia.
+
+
+== Taxonomy ==
+The species was first described by John McClelland in 1840 based on specimens obtained in Manipur, India. It was described more detailed by Percy Eld in 1841; it was suggested to call the deer Cervus Eldii. McClelland coined the scientific name Cervus (Rusa) frontals in 1843.
+In 1850, John Edward Gray proposed the name Panolia eldii for the deer. It has recently been proposed that it should be moved back to the genus Panolia on the basis of recent genetic findings that place it closer to Pere David's deer than to other members of the genus Rucervus.The three subspecies of the Eld's deer are:
+Rucervus eldii eldii: The Manipuri brow-antlered deer is found in Manipur, India. It is called the sangai in Meitei.
+R. e. thamin: The Burmese brow-antlered deer found in Myanmar, and westernmost Thailand.
+R. e. siamensis: The Thai brow-antlered deer is found in Cambodia, China, Laos, Thailand and Vietnam, and should perhaps be treated as a separate species. The population on the Chinese island of Hainan is sometimes considered another subspecies, P. e. hainanus, but this is not supported by genetic evidence. It was described by Lydekker in 1915.
+
+
+== Appearance ==
+The following measurements have been reported for the Eld's deer:
+Head–body length: 150–180 cm (59–71 in)
+Shoulder height: 110–125 cm (43–49 in)
+Tail length: 20–30 cm (8–12 in)
+Weight: 125–175 kg (276–386 lb)
+Antler length: 99 cm (39 in)
+The deer are generally of medium size and are similar to the size and shape of the related barasingha (R. duvaucelli). The species has a very regal and graceful Cervus-like physique. Its legs are thin and long, and has a long body with a large head on a thin neck. The throat of a male has a thick mane of long hair. Males (stags) are taller and heavier than the females (hinds or does). Their coats, rough and coarse, change colour with the season; in summer the colour is reddish-brown, while in winter, it turns dark brown, with males tending to be darker than the females. The tail is short in length and the rump has no distinct patch. Despite these features, they are actually related to the Père David's deer. The antlers, bow- or lyre-shaped, do not grow upwards, but tend to grow outwards and then inwards; a smaller branch grows towards the front of the head. The brow tines are especially long and noticeable. The brow-antlered deer is so named because they have long brow tines. The antlers of Eld's deer are structurally different from those of barasingha but have similarities to those of Père David's deer, consistent with the genetic relationship. They shed their antlers every year, with the largest size attained during the breeding season.
+
+
+== Conservation status ==
+The conservation status of three subspecies of Eld's deer, by country, are:
+
+
+=== India ===
+The Keibul Lamjao National Park (KLNP), covering an area of 40 km2 (15.4 sq mi) of marshland called the Phumdis within the larger Loktak Lake, was gazetted in 1977 specifically to protect the Rucervus eldii eldii, the sangai in Meitei. Over time, public awareness and local support have evolved for conserving the subspecies of the endemic endangered Elds' deer. Concerted actions have been initiated to stop encroachment of the park and adequate security arrangements have been made to stop poaching. This fact is very somberly presented in a story form in a popular children's magazine called Chandamama, which gives a first-person symbolic narrative by the affected 'deer' itself. The final conclusion by the deer, quoted below, concisely puts the security provided in the park in a proper perspective.
+" 'Thanks to these youngsters who live nearby', he said. I was happy and felt indebted to the youngsters for saving our lives. My friend added that these people really loved and respected the Sangai deer. They believed that killing the Sangai was an unpardonable sin. According to a Meitei legend, the Sangai are the link between humans and nature. So, killing us would mean breaking a bond. My friend informed me that people concerned about animals like us have formed a group. They teach others to protect animals, too.The news that people are trying their best to save the phumdis, deer like me, and the Loktak Lake, infuses new hope in me. 'How nice of them!' I thought.
+Anyway, it is getting dark and my friend and I have to return to our herd. And those of you who are around can enjoy our dancing gait as we trot back home. It would be great if I could meet you again. We could dance together at KLNP, if you can make it here some time!"
+The home range of brow-antlered deer in the park is confined to 15–20 km2 (5.8–7.7 sq mi) in the southwestern part of the lake where phumdis on which the deer thrive are abundant. A study conducted on the proportion, on the basis of body weight of stag, hind and fawn, is reported to be 4:2:1. The sangai distribution dictated by shelter and availability of food is high near Toyaching, Pabotching and the Yang Kokchambi area.Censuses conducted by the wildlife wing of the Forest Department in 1975, 1990, 2000 and 2003 has shown the Eld's deer population was 14, 76, 162 and 180, respectively. The 2000 survey of 162 deer included 54 stags, 76 hinds and 32 fawns. The reports of 2004 indicate a figure of 182 as referred in another section here, which shows the subspecies in Manipur is on the rise.A successful captive breeding programme is underway at the Alipore Zoological Gardens in Kolkata, and many specimens of the deer have been bred here.
+
+
+=== Burma ===
+For protection of the thamin subspecies of the Eld's deer, Chatthin Wildlife Sanctuary and Shwesettaw Wildlife Sanctuary (both protected sanctuaries) and Alaungdaw Kathapa National Park were chosen. Chatthin Wildlife Sanctuary, with an area of 104 sq mi (269.4 km2) in Myanmar's central plains, 125 sq mi (323.7 km2) northwest of the city of Mandalay, has Indaing deciduous broadleaf forest dominated by Dipterocarpus tuberculatus and is the habitat for four species of deer: thamin, muntjac (Muntiacus muntjac), hog deer (Axis porcinus), and sambhar (Rusa unicolor).  Subject to indiscriminate hunting in the past (till the ownership of guns was controlled after the 1960s), the thamin, highly threatened, now has a population of about 1,000. Initially, the Smithsonian National Zoo acquired a few thamin for observations and subsequently shifted a few to its Conservation and Research Center at Front Royal, Virginia for biological study.
+For a cross–check of the biological studies done at the research center, the Smithsonian Institution selected the Chatthin Wildlife Sanctuary, a protected park. Special studies on the thamin deer were conducted by the conservation scientists headed by Christen Wemmer of the Smithsonian. They gathered details on the biology and survival of the species by duly correlating with the changes that occurred in the ecology of the region of the Chatthin Wildlife Sanctuary. Under the research project study, the ecology of thamin and a series of training courses in biodiversity were organised. The thamin's life cycle studies on 11 male and eight female radio–collared deer, supported by field studies by the scientists, revealed:
+Its life cycle was well-tuned to the seasonal rhythm of its environment.
+An average group size was 2.5 per 1.6 km2 (0.62 sq mi); deer mother with young appeared to be the basic social unit.
+Males were in velvet when they were in bachelor groups.
+After new grass sprouts in the ashes of February and March fires, they gathered to graze on tender shoots.
+Males moved through the herds seeking receptive females.
+March and April were the months of rut.
+Males with their newly hardened antlers were in a state of anorexia and sexual obsession during this period.
+They operated in a specific home range of about 3.5 sq mi (9.1 km2) to 2.7 sq mi (7.0 km2).
+When food was short, some animals migrated into farmland for a few months before returning to the park; during the day they hid in small patches of degraded forest and at night they forayed into the croplands.
+Smithsonian National Zoological Park, which has been closely associated with the preservation of the thamin deer, has in its conclusive observations stated: "Chatthin Wildlife Sanctuary (CWS) in Myanmar (Burma) protects the largest population of the endangered Eld's deer left in the world. It also represents one of the largest remaining patches of dipterocarp forest–a dry forest that is one of the most threatened and least protected forest types globally. Local people rely on these forests for their livelihood. The forests provide wood, food, shelter, and medicine. Restricting people's access to these forests by declaring them protected is probably not a sustainable solution and will put greater burden on lower income households potentially increasing poverty. However, if people continue to use and abuse forests unregulated they will disappear and with them the Eld's deer and many other species." 
+With external funding for such protection drying up, though, the efforts had not yielded encouraging results and the conclusion was the conditions were not conducive even to protect the protected parks given the political and funding situation in the country.
+The picture is not encouraging in Cambodia, Laos and Vietnam, either. The Burmese brow-antlered deer is 'Near Threatened' and still occurs in reasonable numbers.
+
+
+=== Thailand ===
+The situation of protected areas for the Eld's deer is much worse in Thailand and along its border areas with Laos and Cambodia; it is feared that it may be difficult to prevent the "decline and likely extirpation of Eld's deer from the wild in Thailand".
+
+
+=== Other countries ===
+In Cambodia, Laos and Vietnam, Eld's deer was hunted for the traditional medicinal trade (particularly of this subspecies) and to meet demand for captive animals (especially from zoos) and forest habitat was degraded (deforested) to meet agriculture and infrastructural developments. The subpopulation in Hainan considered as a subspecies by Chinese conservationists was almost extinct in the wild.In the Savannakhet Province of Laos, conservation efforts centred around community management caused the local population to increase from 80 to 170. A 130,000 hectare National Eld’s Deer Sanctuary was created in the area.
+
+
+== Assessment ==
+In over 200 recent years of known history, the number of this species has declined substantially. Based on estimated rates of the decline of this species assessed in three generations (supposed to be at least a 15-year period) for all the species, the average value is reported to be in excess of 50%. Based on this assessment, IUCN has categorized the species as Endangered. In this assessment for determining the species-level, the numbers in India were considered to be numerically small (also found to be increasing), hence the numbers of wild populations only of Eld's deer P. e. thamin in Myanmar and P. e. siamensis of Cambodia, Laos and Vietnam were considered. The decline in population has been mainly attributed to hunting. In the case of the Myanmar thamin, the decline is discernible but not striking. The categorization is considered a middle-ground situation considering the extensively diverse conditions and conservation trends in the geographically isolated and distinct populations of this species.
+
+
+== Subspecies ==
+
+
+=== Breeding ===
+Female Eld's deer are generally found alone or in pairs with their young, but during the mating season, females and their young gather in herds of up to 50 individuals. Males also move around singly except during mating season. When rutting takes place, males compete with each other to gain control of a harem of females with which they can then mate. After a long gestation period, normally a single calf is born. The young have white spots at birth which fade away as they grow; they are weaned at seven months of age, and become sexually mature from 18 months of age onwards. The gestation period for three species is 220 to 240 days, with birthing occurring:.
+For Manipur deer, between October and end of December
+For the Burmese thamin, between October and November
+For the siamensis deer in Thailand, Laos, and Cambodia, between October and November
+
+
+=== Numbers in the wild ===
+In India, the Eld's deer sangai subspecies  is confined to the peculiar floating bog called Phumdis in Loktak Lake and is numbered at less than a few hundred animals. The subspecies P. e. siamensis, which occupied the vast monsoon forests from Thailand to Hainan was extinct in Thailand, very few in number in Laos and Cambodia, and almost extinct in Vietnam. A few hundred deer were protected in a large enclosure in Hainan Island, China. The estimated figures are:
+
+180 animals (2004) of P. e. eldii in Manipur
+2,200 (United Nations estimate) – 1992 survey for P. e. thamin of Burma and Thailand
+In low tens (2004) – for P. e. siamensis, considered as possibly extinct in Laos, Cambodia, and Vietnam
+
+
+=== Numbers in captivity (zoos) ===
+In 2003, the estimated number of captive animals of the three subspecies in zoos were 180 P. e. eldii, 1100 P. e. thamin and 23 P. e. siamensis.
+
+
+== Peculiarities ==
+Peculiarities to each subspecies include:
+R. e. eldii of Manipur, India is associated with wetlands. It has adaptations of the hooves (feet) to move easily in their marshland (boggy ground) habitat of phumdis. It lives in significantly different ecosystems compared to other subspecies and in divergent morphology. Antlers are shed every year and reach their largest size during the breeding season.
+R. e. thamin of Burma and Thailand are not associated with wetlands and live in three forest types: indaing forest (dominated by the tree Dipterocarpus tuberculatus) equivalent to deciduous dipterocarp forest (dipterocarp trees which belong to the family Dipterocarpaceae are resinous trees found in the Old World tropics) of Indochina and Thailand, deciduous forests of dry (thandahat), and mixed (teak).
+R. e. siamensis of Thailand, Laos, Cambodia, and Vietnam are not associated with wetlands. They are found in deciduous dipterocarp forests.
+
+
+== Habits ==
+Some observations on the habits of Eld's deer common to all three subspecies are a) active most of the time, seek shelter from the midday sun and migrate for short periods seeking water in the dry season and food in the growing season, b)seek areas that are seasonally burned in search of new grasses that grow after the burn, c) their diets comprise a variety of grasses, herbaceous plants, and shoots, grasses, fruit and wetland plants and they poach into cultivated crops to graze and browse in nearby fields of rice, lentils, maize, peas and grapes.
+
+
+== Threats ==
+Thamin are prized as game by hunters due to their impressive antlers and hides that are in demand in local markets. They are also widely hunted for food; they were believed to have been used to feed armies during many Asian wars. Their population has additionally declined due to intense development activities necessitating reclamation of land for grazing, cultivation and fish farming within their range. In Myanmar, deforestion of the diperocarp forests is cited as a reason for the threat faced by the thamin deer. The habitat available for their protection is very limited; only 1% of the protected forests are suitable for its protection in South Asia. Even in protected areas, the animals are poached. Another striking problem is finding adequate funds and political will to protect the species. The species have a fragmented distribution and are therefore at risk from inbreeding and loss of genetic variation. The film The Return of Sangai is a documentary by George Thengummoottil about the species in Keibul Lamjao National Park.

+Eld's deer (Rucervus eldii or Panolia eldii), also known as the thamin or brow-antlered deer, is an endangered species of deer endemic to South Asia.
+
+
+== Taxonomy ==
+The species was first described by John McClelland in 1840 based on specimens obtained in Manipur, India. It was described more detailed by Percy Eld in 1841; it was suggested to call the deer Cervus Eldii. McClelland coined the scientific name Cervus (Rusa) frontals in 1843.
+In 1850, John Edward Gray proposed the name Panolia eldii for the deer. It has recently been proposed that it should be moved back to the genus Panolia on the basis of recent genetic findings that place it closer to Pere David's deer than to other members of the genus Rucervus.The three subspecies of the Eld's deer are:
+Rucervus eldii eldii: The Manipuri brow-antlered deer is found in Manipur, India. It is called the sangai in Meitei.
+R. e. thamin: The Burmese brow-antlered deer found in Myanmar, and westernmost Thailand.
+R. e. siamensis: The Thai brow-antlered deer is found in Cambodia, China, Laos, Thailand and Vietnam, and should perhaps be treated as a separate species. The population on the Chinese island of Hainan is sometimes considered another subspecies, P. e. hainanus, but this is not supported by genetic evidence. It was described by Lydekker in 1915.
+
+
+== Appearance ==
+The following measurements have been reported for the Eld's deer:
+Head–body length: 150–180 cm (59–71 in)
+Shoulder height: 110–125 cm (43–49 in)
+Tail length: 20–30 cm (8–12 in)
+Weight: 125–175 kg (276–386 lb)
+Antler length: 99 cm (39 in)
+The deer are generally of medium size and are similar to the size and shape of the related barasingha (R. duvaucelli). The species has a very regal and graceful Cervus-like physique. Its legs are thin and long, and has a long body with a large head on a thin neck. The throat of a male has a thick mane of long hair. Males (stags) are taller and heavier than the females (hinds or does). Their coats, rough and coarse, change colour with the season; in summer the colour is reddish-brown, while in winter, it turns dark brown, with males tending to be darker than the females. The tail is short in length and the rump has no distinct patch. Despite these features, they are actually related to the Père David's deer. The antlers, bow- or lyre-shaped, do not grow upwards, but tend to grow outwards and then inwards; a smaller branch grows towards the front of the head. The brow tines are especially long and noticeable. The brow-antlered deer is so named because they have long brow tines. The antlers of Eld's deer are structurally different from those of barasingha but have similarities to those of Père David's deer, consistent with the genetic relationship. They shed their antlers every year, with the largest size attained during the breeding season.
+
+
+== Conservation status ==
+The conservation status of three subspecies of Eld's deer, by country, are:
+
+
+=== India ===
+The Keibul Lamjao National Park (KLNP), covering an area of 40 km2 (15.4 sq mi) of marshland called the Phumdis within the larger Loktak Lake, was gazetted in 1977 specifically to protect the Rucervus eldii eldii, the sangai in Meitei. Over time, public awareness and local support have evolved for conserving the subspecies of the endemic endangered Elds' deer. Concerted actions have been initiated to stop encroachment of the park and adequate security arrangements have been made to stop poaching. This fact is very somberly presented in a story form in a popular children's magazine called Chandamama, which gives a first-person symbolic narrative by the affected 'deer' itself. The final conclusion by the deer, quoted below, concisely puts the security provided in the park in a proper perspective.
+" 'Thanks to these youngsters who live nearby', he said. I was happy and felt indebted to the youngsters for saving our lives. My friend added that these people really loved and respected the Sangai deer. They believed that killing the Sangai was an unpardonable sin. According to a Meitei legend, the Sangai are the link between humans and nature. So, killing us would mean breaking a bond. My friend informed me that people concerned about animals like us have formed a group. They teach others to protect animals, too.The news that people are trying their best to save the phumdis, deer like me, and the Loktak Lake, infuses new hope in me. 'How nice of them!' I thought.
+Anyway, it is getting dark and my friend and I have to return to our herd. And those of you who are around can enjoy our dancing gait as we trot back home. It would be great if I could meet you again. We could dance together at KLNP, if you can make it here some time!"
+The home range of brow-antlered deer in the park is confined to 15–20 km2 (5.8–7.7 sq mi) in the southwestern part of the lake where phumdis on which the deer thrive are abundant. A study conducted on the proportion, on the basis of body weight of stag, hind and fawn, is reported to be 4:2:1. The sangai distribution dictated by shelter and availability of food is high near Toyaching, Pabotching and the Yang Kokchambi area.Censuses conducted by the wildlife wing of the Forest Department in 1975, 1990, 2000 and 2003 has shown the Eld's deer population was 14, 76, 162 and 180, respectively. The 2000 survey of 162 deer included 54 stags, 76 hinds and 32 fawns. The reports of 2004 indicate a figure of 182 as referred in another section here, which shows the subspecies in Manipur is on the rise.A successful captive breeding programme is underway at the Alipore Zoological Gardens in Kolkata, and many specimens of the deer have been bred here.
+
+
+=== Burma ===
+For protection of the thamin subspecies of the Eld's deer, Chatthin Wildlife Sanctuary and Shwesettaw Wildlife Sanctuary (both protected sanctuaries) and Alaungdaw Kathapa National Park were chosen. Chatthin Wildlife Sanctuary, with an area of 104 sq mi (269.4 km2) in Myanmar's central plains, 125 sq mi (323.7 km2) northwest of the city of Mandalay, has Indaing deciduous broadleaf forest dominated by Dipterocarpus tuberculatus and is the habitat for four species of deer: thamin, muntjac (Muntiacus muntjac), hog deer (Axis porcinus), and sambhar (Rusa unicolor).  Subject to indiscriminate hunting in the past (till the ownership of guns was controlled after the 1960s), the thamin, highly threatened, now has a population of about 1,000. Initially, the Smithsonian National Zoo acquired a few thamin for observations and subsequently shifted a few to its Conservation and Research Center at Front Royal, Virginia for biological study.
+For a cross–check of the biological studies done at the research center, the Smithsonian Institution selected the Chatthin Wildlife Sanctuary, a protected park. Special studies on the thamin deer were conducted by the conservation scientists headed by Christen Wemmer of the Smithsonian. They gathered details on the biology and survival of the species by duly correlating with the changes that occurred in the ecology of the region of the Chatthin Wildlife Sanctuary. Under the research project study, the ecology of thamin and a series of training courses in biodiversity were organised. The thamin's life cycle studies on 11 male and eight female radio–collared deer, supported by field studies by the scientists, revealed:
+Its life cycle was well-tuned to the seasonal rhythm of its environment.
+An average group size was 2.5 per 1.6 km2 (0.62 sq mi); deer mother with young appeared to be the basic social unit.
+Males were in velvet when they were in bachelor groups.
+After new grass sprouts in the ashes of February and March fires, they gathered to graze on tender shoots.
+Males moved through the herds seeking receptive females.
+March and April were the months of rut.
+Males with their newly hardened antlers were in a state of anorexia and sexual obsession during this period.
+They operated in a specific home range of about 3.5 sq mi (9.1 km2) to 2.7 sq mi (7.0 km2).
+When food was short, some animals migrated into farmland for a few months before returning to the park; during the day they hid in small patches of degraded forest and at night they forayed into the croplands.
+Smithsonian National Zoological Park, which has been closely associated with the preservation of the thamin deer, has in its conclusive observations stated: "Chatthin Wildlife Sanctuary (CWS) in Myanmar (Burma) protects the largest population of the endangered Eld's deer left in the world. It also represents one of the largest remaining patches of dipterocarp forest–a dry forest that is one of the most threatened and least protected forest types globally. Local people rely on these forests for their livelihood. The forests provide wood, food, shelter, and medicine. Restricting people's access to these forests by declaring them protected is probably not a sustainable solution and will put greater burden on lower income households potentially increasing poverty. However, if people continue to use and abuse forests unregulated they will disappear and with them the Eld's deer and many other species." 
+With external funding for such protection drying up, though, the efforts had not yielded encouraging results and the conclusion was the conditions were not conducive even to protect the protected parks given the political and funding situation in the country.
+The picture is not encouraging in Cambodia, Laos and Vietnam, either. The Burmese brow-antlered deer is 'Near Threatened' and still occurs in reasonable numbers.
+
+
+=== Thailand ===
+The situation of protected areas for the Eld's deer is much worse in Thailand and along its border areas with Laos and Cambodia; it is feared that it may be difficult to prevent the "decline and likely extirpation of Eld's deer from the wild in Thailand".
+
+
+=== Other countries ===
+In Cambodia, Laos and Vietnam, Eld's deer was hunted for the traditional medicinal trade (particularly of this subspecies) and to meet demand for captive animals (especially from zoos) and forest habitat was degraded (deforested) to meet agriculture and infrastructural developments. The subpopulation in Hainan considered as a subspecies by Chinese conservationists was almost extinct in the wild.In the Savannakhet Province of Laos, conservation efforts centred around community management caused the local population to increase from 80 to 170. A 130,000 hectare National Eld’s Deer Sanctuary was created in the area.
+
+
+== Assessment ==
+In over 200 recent years of known history, the number of this species has declined substantially. Based on estimated rates of the decline of this species assessed in three generations (supposed to be at least a 15-year period) for all the species, the average value is reported to be in excess of 50%. Based on this assessment, IUCN has categorized the species as Endangered. In this assessment for determining the species-level, the numbers in India were considered to be numerically small (also found to be increasing), hence the numbers of wild populations only of Eld's deer P. e. thamin in Myanmar and P. e. siamensis of Cambodia, Laos and Vietnam were considered. The decline in population has been mainly attributed to hunting. In the case of the Myanmar thamin, the decline is discernible but not striking. The categorization is considered a middle-ground situation considering the extensively diverse conditions and conservation trends in the geographically isolated and distinct populations of this species.
+
+
+== Subspecies ==
+
+
+=== Breeding ===
+Female Eld's deer are generally found alone or in pairs with their young, but during the mating season, females and their young gather in herds of up to 50 individuals. Males also move around singly except during mating season. When rutting takes place, males compete with each other to gain control of a harem of females with which they can then mate. After a long gestation period, normally a single calf is born. The young have white spots at birth which fade away as they grow; they are weaned at seven months of age, and become sexually mature from 18 months of age onwards. The gestation period for three species is 220 to 240 days, with birthing occurring:.
+For Manipur deer, between October and end of December
+For the Burmese thamin, between October and November
+For the siamensis deer in Thailand, Laos, and Cambodia, between October and November
+
+
+=== Numbers in the wild ===
+In India, the Eld's deer sangai subspecies  is confined to the peculiar floating bog called Phumdis in Loktak Lake and is numbered at less than a few hundred animals. The subspecies P. e. siamensis, which occupied the vast monsoon forests from Thailand to Hainan was extinct in Thailand, very few in number in Laos and Cambodia, and almost extinct in Vietnam. A few hundred deer were protected in a large enclosure in Hainan Island, China. The estimated figures are:
+
+180 animals (2004) of P. e. eldii in Manipur
+2,200 (United Nations estimate) – 1992 survey for P. e. thamin of Burma and Thailand
+In low tens (2004) – for P. e. siamensis, considered as possibly extinct in Laos, Cambodia, and Vietnam
+
+
+=== Numbers in captivity (zoos) ===
+In 2003, the estimated number of captive animals of the three subspecies in zoos were 180 P. e. eldii, 1100 P. e. thamin and 23 P. e. siamensis.

+The pied tamarin (Saguinus bicolor), sometimes referred to as the Brazilian bare-faced tamarin, is a Critically Endangered primate species found in a restricted area of the Brazilian Amazon Rainforest. It was named the mascot of Manaus, Brazil in 2005. The species is endangered due to the increasing size of the city of Manaus which is encroaching on their native habitat.
+
+
+== Distribution and habitat ==
+A New World monkey, it is found at the city limits of Manaus, the capital of the Amazonas state of Brazil and up to 35 km to the north and 100 km to the east. The main distribution is in the rio Cuieiras and rio Preto da Eva interfluvium. Pied tamarins are also found in the adjacent rio Preto da Eva and rio Urubu interfluvium, but are comparatively rare. There appears to be interspecific competition between the pied tamarin and the red-handed tamarin with the red-handed tamarin gradually displacing the pied tamarin from areas of its historical distribution. Therefore there are multiple threats to the long-term survival of the pied tamarin that stem from habitat destruction and from interspecific competition.
+The pied tamarin is found in old-growth forests, sand forest and smaller secondary forest fragments. Their density is higher in secondary forest fragments than in primary forest.
+
+
+== Description ==
+The pied tamarin's body measures 20.8–28.3 cm.; including the tail it measures 33.5–42.0 cm. The tamarin has a brown lower body and a fluffy white upper body. Their face is black and hairless, the reason for its nickname: the Brazilian bare-faced tamarin.
+The pied tamarin does not have nails, but instead has claws that they adapted in order to quickly scale trees in order to retrieve food or escape predators. These nails also allow the tamarin to dig into tree bark and extract sap which they then eat.Males weigh 428 grams (n = 4). Its life expectancy is approximately 10 years in the wild.
+
+
+== Behavior and reproduction ==
+
+
+=== Group Life ===
+Individuals live in groups of 2 to 15 members with little intra-group competition. Average group size in the Reserva Florestal Adolpho Ducke is 4.8 individuals per group (n = 41), and other areas around Manaus reported mean group sizes of 6.19 ± 2.62 (n = 46). A tamarin group has a home range of 10-100 ha.
+Tamarins are unlike most other mammals in the sense that the females are considered to be the dominant gender. In each group of individuals only one female is selected to breed and reproduce children. This individual is called the "Alpha Female" and reproduction by other females of the group is behaviorally suppressed. The gestation lasts 140–170 days and mothers typically give birth to twins. Although they generally give birth to twins the fact that only one female per group can produce offspring is a major cause in their reduced population size. Young tamarins are cared for primarily by the father and turned over to the mother only to nurse; however, the entire group helps with the care of the younglings that the alpha female birthed.
+
+
+=== Diet ===
+Tamarins are omnivorous, their diet consisting of fruit, flowers, nectar, insects, spiders, small vertebrates and bird eggs. Its natural predators are small cats, birds of prey, and snakes. In urban settings like Manaus, the main predators are domestic and feral cats and dogs. Because of the destruction of its natural habitat, the species is at risk which is why the species has landed on the IUCN red list for endangered species as well as the top 25 most endangered primates list in Brazil.
+
+
+== Conservation ==
+
+
+=== Classification ===
+As of 2015, the pied tamarin is rated critically endangered by the IUCN Red List. The pied tamarin's population is expected to decline 80% by 2033 due to anthropogenic threats, competition with golden-handed tamarin (Saguinus midas) and disease. Within the Manaus area, pied tamarins are threatened by domestic and feral cats and dogs, electrocution from power lines, and the pet trade. Additionally, rural settlement and increasing livestock agriculture continue to encroach upon and degrade the pied tamarin's remaining habitat.
+
+
+=== Protection ===
+The pied tamarin is protected in some parts of its range, such as in Sumaúma State Park (52 ha), Adolfo Ducke Forest Reserve (18,240 ha) and less than half of Puranga Conquista Sustainable Development Reserve (157,807 ha). The Centro de Instrução de Guerra na Selva (CIGS)(115,000 ha) is an important protected area for the species, however it is not a conservation area but a military jungle training facility and so the area's status is uncertain. This organism is endangered due to its severe threat of species encroaching on its habitat and this will cause various issues to the ecosystem and environment.
+Both European and American zoos and conservation services have pitched in financially to help out in saving the pied tamarin species. While there are only two areas in the world that are protected for the tamarins, and both are under 50 hectares, the conservation efforts have allowed for the reforestation of these places and the slow and uncertain return of the tamarins native habitat.There is an established captive breeding program for the pied tamarin and an official studbook. As of 2009, there are 172 pied tamarins in captivity and all are registered property of the Brazilian government. Unfortunately for the tamarins, their captive breeding success rate is limited and thus it is difficult to ressurect the population artificially.
+
+
+== Endangerment ==
+
+
+=== Causes ===
+The tamarins live nearby the rapidly growing city of Manaus, and as the city's area increases in size, the tamarins habitat disappears. When they can avoid the busy automobile traffic and the electric power lines, the pied tamarin reside in the small sections of forest that still remain in Manaus.
+
+
+=== Environmental Impact ===
+Being an omnivore, the pied tamarins diet consists highly of plants. They pick up plant seeds when they eat and disperse them around their environment, thus bolstering their ecosystem. They also dine on small animals, which keeps the insect and amphibian populations in check. With the declining tamarin population, the issue becomes bigger than just the primates, but now turns into an ecosystem issue. There is no way to know for certain how the loss of the pied tamarin population will affect the Amazonian ecosystem, but there almost undoubtedly will be effects.

+The black-capped squirrel monkey (Saimiri boliviensis) is a species of New-World monkey native to the upper Amazon basin in Bolivia, western Brazil and eastern Peru. They weigh between 365 and 1135 grams and measure, from the head to the base of the tail, between 225 and 370mm. Black-capped squirrel monkeys are primarily tree-dwelling and are found in both native and plantation forests as well as some farmed areas near running water. Their diet is omnivorous and mostly consists of flowers, fruit, leaves, nuts, seeds, insects, arachnids, eggs and small vertebrates. They mostly live in female-dominated troops of around 40 to 75 monkeys, with males having been observed to disperse to live in all-male troops after reaching sexual maturation. Their current conservation status according to the IUCN is 'Least Concern'. The species belongs to the genus Saimiri and has two subspecies, S. b. boliviensis (the Bolivian squirrel monkey) and S. b. peruviensis (the Peruvian squirrel monkey).
+
+
+== Description ==
+
+The black-capped squirrel monkey displays sexual dimorphism, with males normally weighing between 550 and 1135 grams and females weighing between 365 and 750 grams. Infants typically weigh between 80 and 140 grams when they are born. Adults of the species measure in length (from the head to the base of the tail) between 250 and 370mm for males and 225 and 295mm for females. The coat of the monkey is short, soft and dense, and the majority of the fur covering the back of the monkey is a grey to olive-brown hue, while the undersides are typically white, yellow or ochre. The head is characteristically black with white arches over the eyes. The tail is the same colour as the body with a black tufted tip and is not prehensile; it usually measures around 350 to 425mm.Physically, the black-capped squirrel monkey is very similar to a number of other species of squirrel monkey, but is distinguishable from other species by a number of features. The most noticeable of these are the dark black cap and the white ‘Roman type’ arch pattern over the monkey's eyes, which is more narrow and rounded than the ‘Gothic type’ arch pattern over the eyes of the other species. The tail of the ‘Roman type’ species is also narrower than that of the ‘Gothic type’.
+
+
+== Evolution ==
+Saimiri boliviensis is thought to have diverged from the Saimiri genus approximately 1.5 million years ago. It has been hypothesised that this diversification occurred due to environmental changes in the Pleistocene period which allowed for thicker vegetation to appear in the Amazonian rainforest.
+
+
+=== Fossils ===
+Several different fossils have been linked to the genus Saimiri through examinations of their dental and cranial morphology, including the Early Miocene fossil Dolichocebus which was discovered  in Gaiman, Argentina and dated to around 20.5 million years ago, and the Middle Miocene fossil of the genus Neosaimiri discovered in La Venta, Colombia, which has been dated to between 12.1 and 12.5 million years ago.
+
+
+=== Taxonomic classification ===
+Originally all squirrel monkeys were considered to be of the same species; they were first divided into two different ‘types’ - ‘Roman’ and ‘Gothic’ - in Paul D. Maclean's article ‘Mirror Display in the Squirrel Monkey, Saimiri sciureus’, published in 1964. Many different opinions on the taxonomic classification of Saimiri boliviensis as a separate species have been published, however various studies conducted by several researchers have concluded that Saimiri boliviensis is one of at most seven different species of Saimiri. Based on the geographical distribution and the morphological and behavioural characteristics of the specimens studied, Hershkovitz proposed the existence of Saimiri boliviensis as a distinct species with two sub-species, Saimiri boliviensis boliviensis and Saimiri boliviensis peruviensis. Based on cranial measurements and coat colouring, Thorington proposed Saimiri sciureus boliviensis as a sub-species of Saimiri sciureus. Another prominent report published in 1993 supports Thorington's classification, however after further investigation into the genetic characteristics of the monkey a more recently published report concludes that Hershkovitz's description is the most accurate. The dispute over the taxonomic and genetic classification of the black-capped squirrel monkey has become increasingly relevant with regards to their use in biomedical research, due to the fact that hybridisation may have an effect on the reproductive capabilities of the monkey, and has the potential to cause a differentiation in its susceptibility to certain pathogens and infections.Alternative or previously proposed taxonomic names include:
+Saimiri sciureus boliviensis
+Callithrix boliviensis (monkeys from Bolivia)
+Callithrix entomophagus  (monkeys from Tefé, Brazil)
+Saimiri boliviensis nigriceps (monkeys from Cosnipata, Peru)
+Saimiri boliviensis pluvialis (monkeys from the Rio Jurua in Brazil)
+
+
+== Distribution and habitat ==
+
+Saimiri displaying the characteristic ‘Roman arch’ facial pattern of the black-capped squirrel monkey have been documented throughout most of Bolivia, northern Peru, and between the Jurua and Purus Rivers in Brazil. They are found in lowland tropical rainforests near water in densely forested and swampy regions. They are predominantly arboreal, and while they utilise all levels of the forests they have been observed to keep mostly to the lower canopies for the purposes of travel and foraging It has been proposed that matrilineal troops of Saimiri boliviensis are formed due to an abundance of fruit and insects present in their habitat, which is not present in the habitats of other species of the Saimiri genus.
+
+
+== Biology ==
+Saimiri boliviensis are mostly arboreal but will occasionally also be found on the forest floor. They are diurnal and have been observed to be most active during the early to mid-morning, before resting for one or two hours in the afternoon, followed by another period of activity from the early afternoon to evening.
+
+
+=== Social systems ===
+The black-capped squirrel monkey is found in female dominated troops of around 45 to 75 monkeys, unlike its relative the Common squirrel monkey which habitually lives in male dominated troops of around 15 to 50.  Similar to most other species of monkeys, female Saimiri boliviensis will remain in the troop into which they are born, while males are more likely to be excluded by more dominant females.  When they reach sexual maturity, male Black-capped squirrel monkeys will disperse from their natal troop into smaller all-male groups, and will eventually join a larger mixed-sex troop, often together with other males from the all-male group. Black-capped squirrel monkey troops display high levels of aggression between females. Female monkeys will often compete with other female members of the troop to determine access to resources, however it has been observed that despite heavy competition for food they still prefer to live in large groups in order to reduce the likelihood of predation.
+
+
+=== Reproduction ===
+
+A Black-capped squirrel monkey will typically reach sexual maturation at around 3 years of age for females and 5 years of age for males. The yearly reproductive cycle of mature Saimiri has been observed by several researchers to be affected by a number of environmental factors, including the cycles of rainfall and levels of illumination in their habitat. The mating season coincides with the dry season, and will typically result in a single infant being born to each mother. It has been suggested that adult female monkeys are more receptive to environmental cues for the mating season to begin, and the response in males is in part attributed to behavioural and scent cues from the females.  During the mating season, males of the species will gain a large amount of subcutaneous upper body fat, leading to what is known as a ‘fatted’ appearance. It has also been observed that the testosterone levels of monkeys of the Bolivian and Peruvian species are noticeably higher during the mating season than those of other species of male Saimiri from Guayana. Males will become more irritable and aggressive, fight more frequently for the purpose of achieving dominance within the troop, and engage in genital display towards less dominant males. It has been observed in both natural and laboratory settings that the hierarchy of the troop may change up to as often as three times in a month, and this will often result in highly aggressive fights which may lead to the complete exclusion of younger adult males from the troop. The scent and behavioural cues of a female monkey assist a male in his judgement of whether or not she will be receptive to his approach and attempt at mating with her. If she is not receptive, the female, sometimes with the aid of other nearby females, will usually chase the male away. Consorting and copulation between a male and female monkey may last between one minute and over an hour depending on the presence of other monkeys and the environment in which it takes place. The gestation period of the monkey has been estimated to last between 160 and 170 days. During the first week following its birth, an infant monkey will cling to its mother's back and will seldom move or be attended to by the mother unless it is in some way in need of assistance.
+
+
+=== Communication ===
+Squirrel monkeys have been found to be some of the most vocal primates, with a large range of different types of calls documented throughout their lifespan. Commonly used sounds include ‘chucks’, a variety of purrs and squawks elicited during the birthing and mating seasons, chirps and peeps used for alarm or attention, as well as aggressive screaming and ‘barking’. Infant Black-capped squirrel monkeys tend to vocally communicate much more than adults. The most common form of infant communication is a number of different ‘peeps’, which begin to occur most frequently at around 2 months of age when the infant starts to spend more time away from its mother. After maturation, the most commonly used call for adult females is a variety of ‘chucks’, used to maintain contact in dense vegetation where visual identification is not possible.
+
+
+=== Food and foraging ===
+Black-capped squirrel monkeys are omnivorous. A typical squirrel monkey diet includes fruits, insects, eggs, small vertebrates, arachnids, leaves, flowers, nuts, seeds, and rarely fungi; however it has been observed that they prefer insects to fruit. Mature Saimiri spend most of the day foraging. They will begin foraging at around 60 to 40 minutes before sunrise and will spend the first part of the day actively feeding on fruits and any insects they are able to hunt while foraging for fruit. They will then adopt more sedate feeding behaviours and spend the rest of the day resting and hunting for more insects.  Often, when food is not scarce, they will stop and rest for an hour or two in the middle of the day when it is too hot to continue. When fruits are scarce, squirrel monkeys have been reported to consume Ascopolyporus, a fungus that is parasitic on scale insects which are parasitic to local bamboo species. Researchers formulate that this is done as an alternative food source during dry seasons.
+
+
+=== Locomotion ===
+Black-capped squirrel monkeys are mostly found in trees and will often leap 1–2 metres between branches. They are capable of moving swiftly through dense vegetation at a four-legged walk or run with diagonal sequence footfalls (wherein the hind leg on one side will touch down followed by the foreleg of the opposite side). They will occasionally adopt a stationary bipedal stance at ground level while foraging. The monkey's tail is usually used for balance, or by infants to secure them to their mother's tail or abdomen.
+
+
+== Conservation status ==
+The black-capped squirrel monkey population has been listed as being of ‘Least Concern’ by the IUCN, despite population numbers being in a general state of decline. It has been determined that the black-capped squirrel monkey is adapts easily to changes or potential threats to its environment, and is not subject to high levels of hunting by humans. According to the IUCN, the main threats to the habitat of the monkey are agricultural and aquacultural uses of their habitat, and the use of the monkey's biological resources for purposes such as hunting, trapping, logging and wood harvesting.

+The black-capped squirrel monkey (Saimiri boliviensis) is a species of New-World monkey native to the upper Amazon basin in Bolivia, western Brazil and eastern Peru. They weigh between 365 and 1135 grams and measure, from the head to the base of the tail, between 225 and 370mm. Black-capped squirrel monkeys are primarily tree-dwelling and are found in both native and plantation forests as well as some farmed areas near running water. Their diet is omnivorous and mostly consists of flowers, fruit, leaves, nuts, seeds, insects, arachnids, eggs and small vertebrates. They mostly live in female-dominated troops of around 40 to 75 monkeys, with males having been observed to disperse to live in all-male troops after reaching sexual maturation. Their current conservation status according to the IUCN is 'Least Concern'. The species belongs to the genus Saimiri and has two subspecies, S. b. boliviensis (the Bolivian squirrel monkey) and S. b. peruviensis (the Peruvian squirrel monkey).

+Sanzinia madagascariensis, also known as the Malagasy tree boa  or Madagascar tree boa, is a boa species endemic to the island of Madagascar. It was considered conspecific with the Nosy Komba ground boa. Like all other boas, it is non-venomous.
+
+
+== Description ==
+ Adults average 4–5 feet (122–152 cm) in length, although 6–7 foot (183–213 cm) specimens are not uncommon. Thermoreceptive pits are located between the labial scales. Females are larger than males.
+It is greenish in colour and is found on the east side of Madagascar.
+
+
+== Distribution and habitat ==
+Endemic to Madagascar. The type locality given is "Madagascar". Favors trees and shrubs near streams, rivers, ponds and swamps.
+
+
+== Conservation status ==
+This species was classified as Vulnerable (VU) on the IUCN Red List of Threatened Species in 2006 with the following criteria: A1cd (v2.3, 1994). This means that a population reduction of at least 20% has been observed, estimated, inferred or suspected over the last 10 years or three generations, whichever is the longer, based on a decline in area of occupancy, extent of occurrence and/or quality of habitat, and based on actual or potential levels of exploitation.
+It is now listed as Least Concern (LC) as it is widespread, present in heavily degraded habitats and it is not subject to any known or suspected threats.Also listed as CITES Appendix I, which means that it is threatened with extinction and CITES prohibits international trade except when the purpose of the import is not commercial, for example for scientific research.
+
+
+== Feeding ==
+Arboreal and generally nocturnal, S. madagascariensis feeds on mammals and birds. Its thermoreceptive pits help it to locate its prey. It will also leave the trees to actively hunt for small mammals on the ground.
+
+
+== Reproduction ==
+Ovoviviparous, females give birth to up to 12 young at a time, each about 15 inches (38 cm) in length.When females become gravid, their skin color darkens. This adaptation provides increased heat absorption for the developing young. After giving birth, the color returns to normal as soon as it next sheds its skin. Neonates are a bright red that may warn predators to "stay away", while simultaneously providing camouflage among brightly colored treetop flowers.
+
+
+== Taxonomy ==
+When Kluge (1991) moved Sanzinia madagascariensis (A.M.C. Duméril & Bibron, 1844) to Boa together with Acrantophis madagascariensis (A.M.C. Duméril & Bibron, 1844), it resulted in homonymy. To fix this nomenclatural problem, he proposed the specific name manditra as a replacement for S. madagascariensis.It has since been shown that the Malagasy boids and the genus Boa do not form a monophyletic group, so that the lumping of Sanzinia, Acrantophis and Boa was incorrect, and the name Sanzinia madagascariensis is therefore the correct name for this species.

+The golden-bellied capuchin (Sapajus xanthosternos), also known as the yellow-breasted or buff-headed capuchin, is a species of New World or neotropical monkey. It lives mainly in trees and are omnivorous, eating a wide variety of both plant and animals as food. Golden-bellied capuchin normal home range is in the Atlantic forest of Brazil and it is critically endangered due to forest fragmentation and habitat loss mainly due to agriculture, there are currently efforts to protect them by the local government.
+
+
+== Characteristics ==
+Although there are differences between individuals as well as between the sexes and across age groups, S. xanthosternos is described as having a distinctive yellow to golden red chest, belly and upper arms. Its face is a light brown and its cap for which the capuchins were first named is a dark brown/black or light brown. Formerly thought to be a subspecies of tufted capuchin (S. apella), it was elevated to the status of species. Despite this previous classification, S. xanthosternos does not have very evident tufts, as they are oriented towards the rear of the skull and are hardly noticeable. A band of short hair around the upper part of the face with speckled colouring contrasts with the darker surrounding areas. The limbs and tail are also darkly coloured.
+
+
+=== Size ===
+Capuchins males stand around 40 cm (16 in) tall weighing an average of 4 kg (8.8 lb). Females are 37 cm (15 in) tall at round 2.5 kg (5.5 lb). Their prehensile tails are about the same length as their bodies and is helpful for swinging and climbing through the canopy. Capuchins have opposable big toes and long fingers assisting with climbing as well.
+
+
+=== Life Span ===
+Capuchins life span is around 15–25 years when living in the wild. They can live much longer in captivity to about 50 years.
+
+
+=== Origins ===
+Capuchins falling under the genus of Sapajus and Cebus are believed to have a common ancestor originating in the Atlantic forest. Primates under the genus Sapajus then continued to live and occupy the Atlantic forest evolving into the species we know today such as Sapajus xanthosternos. 
+
+
+== Distribution and habitat ==
+Populations of S. xanthosternos are restricted to the Atlantic forest of south-eastern Bahia, Brazil, due possibly to high degrees of interference from humans. Historically they probably would have inhabited the entire area east of, and north to, the Rio São Francisco.The largest continuous area of forest in its known range, the Una Biological Reserve in Bahia, is estimated to contain a population of 185 individuals. As of 2004, there were 85 individuals in zoos and breeding facilities in Europe and Brazil.
+
+
+=== Habitat Fragmentation ===
+The native biome of S. xanthosternos, the Atlantic forest of Brazil, is heavily fragmented with the majority of remaining forest fragment smaller than 50 hectares. Some of the remaining forests are maintained due to the presence of agroforests called cabrucas. The presence of these agroforests provide a habitat for local flora and fauna including S. xanthosternos.  The remaining forest fragments tend to be surrounded by human activity such as farms, this is both beneficial and detrimental to the capuchins since they are able to raid crops to supplement their diet. This behavior, however, may lead to more confrontation and hunting by humans.The ideal size of a forest fragment in order to properly sustain a population of S. xanthosternos is deemed to be larger than a range of approximately 400 to 700 hectares depending on local conditions, with currently approximately 2% of forest fragments being over 400 hectares this poses an issue for conservation.
+
+
+== Behavior ==
+Capuchins are arboreal, living mainly in trees.
+
+
+=== Social ===
+Capuchins live in groups consisting of about 3-30 individuals with a hierarchy determining their social status. There is usually an equal number of males to females living together with a male and female alpha. The rest of the individuals are lower in rank. The alpha male will defend his territory if approached by another group. Capuchins spend much of their time grooming each other as a means of socialization with the alpha getting the most attention. They often participate in “urine washing” by covering themselves in their own urine to mark their territory. This scent will travel with them.
+
+
+=== Communication ===
+Capuchins communicate making short and frequent yipping whines similar to a newborn pup. When in danger, they emit a two-toned clunking noise. Many of the noises Capuchins make are similar to bird sounds. They also communicate through chemical signals to express territory boundaries as well as during mating rituals.
+
+
+=== Space Use ===
+S. xanthosternos will use forest areas with more cover and protection from predators, even if it means avoiding areas of high food availability. There are also behavioral differences when the capuchins are within different types of forest, such as being more spread out in the capruca while staying lower in the canopy and closer together in secondary forests. Capuchins will change strategies in order to reduce the risk that they perceive within their habitats.
+
+
+=== Predation ===
+Their coloration makes them camouflage into their habitat making them more difficult to spot by a predator. When capuchins are on the ground or near water, they can fall prey to predators such as snakes, large raptors, crocodiles, or large carnivorous mammals. The larger the group, the less chance they have of becoming prey due to a higher number of vigilant individuals. If a predator is spotted, the Capuchin will alert the others using their alarm call. Capuchins have acute olfactory senses helping them to distinguish scent marks left behind by other groups.
+
+
+==== Hunting ====
+Hunting is a major threat to S. xanthosternos and its ability to have populations survive long-term in forest fragments. Hunting is especially problematic in areas close to human activity such as agroforests (cabrucas) and farmland. There is an elevated perceived risk of predation in the capuchins behavior when it is in an area of forest that give a greater advantage to predators, such as reduced canopy coverage in cabruca and in areas that transition from other forest types to a cabruca.
+
+
+=== Diet ===
+Golden-bellied capuchins feed on both plant and animal origins making them omnivores. They mostly feed on plants such as fruits, seeds, flowers, nuts, leaves and stems, and nectar. They also eat insects, bird eggs, frogs, small reptiles, birds, bats, or other small mammals. Capuchins residing near marine areas will feed on oysters, crabs or other shellfish. Sapajus xanthosternos has been known to hunt and eat various small lizards, sometimes ripping limbs off of the lizards before consuming them.
+
+
+=== Reproduction ===
+Capuchins can mate year-round but females will give birth every two years. A female's gestation period is 150–180 days and give birth to one infant. Newborns are 100% reliant on their mothers for their first year of life and become independent around 6–12 months. Female Capuchins reach maturity around 4–5 years old and start mating and giving birth at 7–8 years old. Males reach maturity and are fertile around 6–8 years.
+
+
+=== Mating ===
+Capuchins mate with more than one partner making them polygynandrous. The alpha-male of the group always has first choice of which female will be his mate. The other males of the group are also sexually active but the alpha has the most reproductive success. The alpha-male is most desired by the females as he will provide the most protection to his young. Unique mating rituals occur in order for the female to attract a male. She will first raise her eyebrows and move her head back and forth. She will touch him and runaway while murmuring noises. The male will make eye contact with her and also make noises. They perform a dance just before mating by jumping and spinning in the air. Just after mating, they will continue the dance for several seconds.
+
+
+== Conservation ==
+
+
+=== Status ===
+The Capuchin is listed by the International Union for Conservation of Nature as critically endangered. The population of the Capuchin within the last 50 years has declined over 50%. Any remaining habitats are protected including the largest place called Una Biological Reserve in Bahia, Brazil, home to about 185 Capuchin.
+
+
+=== Threats ===
+Capuchins are endemic to Brazil's rainforests which are in danger of deforestation for agriculture and logging. This is causing fragmentation of the forests threatening their habitat. Groups of Capuchins are being separated from one another causing interbreeding which results in biodiversity loss ultimately causing an extinction vortex. Capuchins are also in danger of being hunted.
+
+
+==== Pet Trade ====
+Capuchins are regularly captured in order to be sold in the illegal pet trade. In relation to species conservation it has been noted that the capture of a female creates a negative impact on a group's ability to survive than if a male is captured. Infants may also be sold into the pet trade, however this can be seen as a byproduct of hunting the mothers.
+
+
+=== Current Efforts ===
+There is an effort in place by the Brazilian National Action Plan for the Conservation of the Northeastern Primates to protect a number of endangered primate species including S. xanthosternos.

+The hamerkop (Scopus umbretta) is a medium-sized wading bird. It is  the only living species in the genus Scopus and the family Scopidae. The species and family was long thought to sit with the Ciconiiformes but is now placed with the Pelecaniformes, and its closest relatives are thought to be the pelicans and the shoebill. The shape of its head with a long bill and crest at the back is reminiscent of a hammer, which has given this species its name after the Afrikaans word for hammerhead. It is a medium-sized waterbird with brown plumage. It is found in Africa, Madagascar and Arabia, living in a wide variety of wetlands, including estuaries, lakesides, fish ponds, riverbanks, and rocky coasts. The hamerkop is a sedentary bird that often shows local movements.
+The hamerkop takes a wide range of prey, mostly fish and amphibians, but shrimps, insects and rodents are taken too. Prey is usually hunted in shallow water, either by sight or touch, but the species is adaptable and will take any prey it can. The species is renowned for its enormous nests, several of which are built during the breeding season. Unusually for a wading bird the nest has an internal nesting chamber where the eggs are laid. Both parents incubate the eggs, and raise the chicks.
+The species is not globally threatened and is locally abundant in Africa and Madagascar, and the International Union for Conservation of Nature (IUCN) has assessed it as being of least concern.
+
+
+== Taxonomy and systematics ==
+The hamerkop was first described by the French zoologist Mathurin Jacques Brisson in 1760 in his landmark Ornithologia which was published two years after the tenth edition of Carl Linnaeus' Systema Naturae. The species was subsequently described and illustrated by French polymath Comte de Buffon. When the German naturalist Johann Friedrich Gmelin revised and expanded Carl Linnaeus's Systema Naturae in 1788 he included the hamerkop and cited the earlier authors. He placed the species in the genus Scopus that had been introduced by Brisson and coined the binomial name Scopus umbretta.Brisson's names for bird genera were widely adopted by the ornithological community despite the fact that he did not use Linnaeus' binomial system. The International Commission on Zoological Nomenclature  ruled in 1911 that Brisson's genera were available under the International Code of Zoological Nomenclature, so Brisson is considered to be the genus authority for the hamerkop. The generic name, Scopus, is derived from the Ancient Greek skia for shadow. The specific name umbretta is modified from the Latin for umber or dark brown.The hamerkop is sufficiently distinct to be placed in its own family, although the relationships of this species to other families has been a longstanding mystery. The hamerkop was usually included in the Ciconiiformes, but is now thought to be closer to the Pelecaniformes. Recent studies have found that its closest relatives are the pelicans and shoebill. Although the hamerkop is the only living member of its family, one extinct species is known from the fossil record. Scopus xenopus was described by ornithologist Storrs Olson in 1984 based on two bones found in Pliocene deposits from South Africa. Scopus xenopus was slightly larger than the hamerkop and Olson speculated based on the shape of the tarsus that the species may have been more aquatic.The hamerkop is also known as the hammerkop, hammerkopf, hammerhead, hammerhead stork, umbrette, umber bird, tufted umber, or anvilhead.
+
+
+=== Subspecies ===
+Two subspecies are recognized - the widespread nominate race S. u. umbretta and the smaller of West African S. u. minor, described by George Latimer Bates in 1931. Two other subspecies have been proposed. S. u. bannermani of south west Kenya is usually lumped with the nominate race. Birds in Madagascar have been suggested to be distinct, in which case they would be placed in the subspecies S. u. tenuirostris. That proposed subspecies was described by Austin L. Rand in 1936. It has also been suggested that birds near the Kavango River in Namibia may be distinct, but no formal description has been made.
+
+
+== Description ==
+
+The hamerkop is a medium-sized waterbird,  standing 56 cm (22 in) high and weighing 470 g (17 oz), although the subspecies  S. u. minor is smaller. Its plumage is a drab brown with purple iridescence on the back; S. u. minor is darker. The tail is faintly barred with darker brown. The sexes are alike and fledglings resembled adults. The bill is long, 80 to 85 mm (3.1–3.3 in), and slightly hooked at the end. It resembles the bill of a shoebill, and is quite compressed and thin, particularly at the lower half of the mandible. The bill is brown in young birds, but becomes black by the time a bird fledges.
+
+The neck and legs are proportionately shorter than those of similar looking Pelecaniformes. The bare parts of the legs are black and the legs are feathered only to the upper part of the tibia. The hamerkop has, for unknown reasons, partially webbed feet. The middle toe is comb-like (pectinated) like a heron's. Its tail is short and its wings are big, wide, and round-tipped; it soars well, although it does so less than the shoebill or storks. When it does so, it stretches its neck forward like a stork or ibis, but when it flaps, it coils its neck back something like a heron. Its gait when walking is jerky and rapid, with its head and neck moving back and forth with each step. It may hold its wings out when running for extra stability.
+
+
+== Distribution and habitat ==
+The hamerkop occurs in Africa south of the Sahara, Madagascar, and coastal south-west Arabia.  It requires shallow water in which to forage, and is found in all wetland habitats, including rivers, streams, seasonal pools, estuaries, reservoirs, marshes, mangroves, irrigated land such as rice paddies, savannahs, and forests. In Tanzania, it has also recently begun to feed on rocky shores.  In Arabia, it is found in rocky wadis with running water and trees. Most are sedentary within their territories, which are held by pairs, but some migrate into suitable habitat during the wet season only. The species is very tolerant of humans and  readily feeds and breeds in villages and other human-created habitats.
+
+
+== Behaviour and ecology ==
+The hamerkop is mostly active during the day, often resting at noon during the heat of the day. They can be somewhat crepuscular, being active around dusk, but are not nocturnal as has sometimes been reported.
+
+
+=== Social behaviour and calls ===
+The hamerkop is mostly silent when alone, but is fairly vocal when in pairs or in groups. The only call it usually makes when alone is a flight-call, a shrill “nyip” or “kek”. In groups, vocalisations include a range of calls including cackles and nasal rattles. One highly social call is the "yip-purr" call. This call is only made in a social context, when at least three birds, but up to 20 are gathered in a flock. Birds start by giving a number of "yip" calls, eventually giving way to purring notes. This call is made with the neck extended and sometimes accompanied by wing flapping, and becomes more vigorous when larger numbers of birds are present.Another common social behaviour is "false mounting", in which one bird stands on top of another and appears to mount it, but they do not copulate. This behaviour has been noted between both mated pairs and unmated birds, and even between members of the same sex and in reversed mountings, where females mount males. Because of this, the behaviour is thought to be social and not related to the pair bond. Dominant birds may signal to subordinates by opening their bills slightly and erecting their crests, but the species is not very aggressive in general towards others of its species. Birds in groups also engage in social allopreening when in groups. One bird presents its face of back of the head to the other to be preened.
+
+
+=== Food and feeding ===
+
+This species normally feeds alone or in pairs, but also feeds in large flocks sometimes. It is a generalist, although amphibians and fish form the larger part of its diet. The diet also includes shrimp, insects, and rodents. The type of food they take seems to vary by location, with clawed frogs and tadpoles being important parts of the diet in East and Southern Africa and small fish being almost the only prey taken in Mali. Because it is willing to take a wide range of food items and also take very small prey, it is not resource-limited and only feeds for part of the day.The usual method of hunting is to walk in shallow water looking for prey. Prey is located differently depending on circumstances; if the water is clear, it may hunt by sight, but if the water is very muddy, it  probes its open bill into water or mud and shuts it. It may shuffle one foot at a time on the bottom or suddenly open its wings to flush prey out of hiding. Prey caught in mud is shaken before swallowing to clean it, or if available, taken to clearer water to do so. The species also feeds while in flight. A bird flies slowly low over the water with legs dangling and head looking down, then dipping feet down and hovering momentarily when prey is sighted. The prey is then snatched with the bill and swallowed in flight. This method of hunting can be very successful, with one birds catching prey on 27 of 33 attempts during one 45-minute session. It is also opportunistic, and feeds on swarming termites when they conduct their nuptial flights, snatching as many as 47 alates (flying termites) in five minutes.This species has been recorded foraging for insects flushed by grazing cattle and buffalo, in a manner similar cattle egrets, and has been observed fishing off the backs of hippopotamuses. It has also been recorded feeding in association with banded mongooses; when a band of mongooses began hunting frogs in dried mud at the side of a pool of water a pair of hamerkops attended the feeding group, catching frogs that escaped the mongooses.
+
+
+=== Breeding ===
+
+The strangest aspect of hamerkop behaviour is the huge nest, sometimes more than 1.5 m (4 ft 11 in) across, and strong enough to support a man's weight. When possible, it is built in the fork of a tree, often over water, but if necessary, it is built on a bank, a cliff, a human-built wall or dam, or on the ground. A pair starts by making a platform of sticks held together with mud, then builds walls and a domed roof. A mud-plastered entrance 13–18 cm (5.1–7.1 in) wide in the bottom leads through a tunnel up to 60 cm (24 in) long to a nesting chamber big enough for the parents and young. Nests have been recorded to take between 10 and 14 weeks to build, and one researcher estimated that they would require around 8,000 sticks or bunches of grass to complete. Nesting material may still be added by the pair after the nest has been completed and eggs have been laid. Much of the nesting material added after completion is not sticks, but an odd collection of random items including bones, hide, and human waste.
+
+Pairs of hamerkop are compulsive nest builders, constructing three to five nests per year whether they are breeding or not. Both members of the pair build the nest, and  the building of nests may have a function in creating or maintaining the pair bond between them. Barn owls and eagle owls may force them out and take over the nests, but when the owls leave, the pair may reuse the nest. Owls may also use abandoned nests, as may snakes, small mammals such as genets, and various birds, and weaver birds, starlings, and pigeons may attach their nests to the outside. A few reports exist of hamerkops nesting close together, including in Uganda, where 639 nests were seen in an area of 8 km2 (3.1 sq mi); even if each pair had made seven nests, this would mean 80 pairs were nesting in that area. The species is not treated as colonial, as it does not habitually nest close together, but is not thought to be highly territorial, either. Even where pairs have home ranges that are more spread out those home ranges overlap and are the boundaries are poorly defined.Breeding happens year-round in East Africa, and in the rest of its range, it peaks at different times, with a slight bias towards the dry season. Pairs engage in a breeding display, then copulate on the nest or on the ground nearby. The clutch consists of three to seven eggs which start chalky white, but soon become stained. The eggs measure 44.5 mm × 33.9 mm (1.75 in × 1.33 in) on average, and weight around 27.8 g (0.98 oz), but considerable variation is seen. Egg size varies by season, by the overall size of the clutch, and from bird to bird. Both sexes incubate the eggs, but  the female seems to do the most of the work. Incubation takes around 30 days from the first egg being laid to hatching, eggs are laid with intervals of one to three days, and they hatch asynchronously.Both parents feed the young, often leaving them alone for long times. This habit, which is unusual for wading birds, may be made possible because of the thick nest walls. The young hatch covered with grey down. By 17 days after hatching, their head and crest plumage is developed, and in a month, their body plumage. They first leave the nest around 44 to 50 days after hatching, but continue to use the nest for roosting at night until they are two months old.
+
+
+== Relationship with humans ==
+Many legends exist about the hamerkop. In some regions, people state that other birds help it build its nest. The ǀXam informants of Wilhelm Bleek said that when a hamerkop flew and called over their camp, they knew that someone close to them had died.It is known in some cultures as the lightning bird, and the Kalahari Bushmen believe or believed that being hit by lightning resulted from trying to rob a hamerkop's nest. They also believe that the inimical god Khauna would not like anyone to kill a hamerkop. According to an old Malagasy belief, anyone who destroys its nest will get leprosy, and a Malagasy poem calls it an "evil bird". Such beliefs have given the bird some protection. A south African name Njaka meaning "rain doctor" is derived from its habit of calling loudly prior to rain.Scopus, a database of abstracts and citations for scholarly journal articles, received its name in honour of this bird, as did the journal of the East African Natural History Society, Scopus.

+The speckled pigeon (Columba guinea), or (African) rock pigeon, is a pigeon that is a resident breeding bird in much of Africa south of the Sahara. It is a common and widespread species in open habitats over much of its range, although there are sizable gaps in its distribution.  It is sometimes referred to as the Guinea pigeon due to its similar coloring to some species of guineafowl.
+
+
+== Taxonomy ==
+In 1747 the English naturalist George Edwards included a description and an illustration of the speckled pigeon in the second volume of his A Natural History of Uncommon Birds. His hand-coloured etching was made from two live birds at the home of the Duke of Richmond in London. Edwards was told that the pigeons had been brought from the inland region of Guinea in West Africa. When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he placed the speckled pigeon with all the other pigeons in the genus Columba. Linnaeus included a brief description, coined the binomial name Columba guinea and cited Edwards' work.There are two recognised subspecies:
+C. g. guinea Linnaeus, 1758 – Mauritania to Ethiopia south to the Democratic Republic of the Congo and northern Malawi
+C. g. phaeonota Gray, G.R., 1856 – southwestern Angola to Zimbabwe and South Africa
+
+
+== Description ==
+This is a large pigeon at 41 cm in length. Its back and wings are rufous, the latter heavily speckled with white spots. The rest of the upperparts and underparts are blue-grey, and the head is grey with red patches around the eye. The neck is brownish, streaked with white, and the legs are red. Sexes are similar, but immatures are browner than adults and lack the red eye patches. The call is a loud  doo-doo-doo.
+
+
+== Behaviour and ecology ==
+The speckled pigeon is frequently seen around human habitation and cultivation. Most of its food is vegetable, and it gathers in large numbers where grain or groundnuts are available. This species builds a large stick nest on protected rocky outcrops and in urban areas often atop covered pergola pillars and on flat roofs under deep eaves and lays two white eggs. Its flight is quick, with regular beats and an occasional sharp flick of the wings that are characteristic of pigeons in general.

+The African penguin (Spheniscus demersus), also known as Cape penguin or South African penguin, is a species of penguin confined to southern African waters. Like all extant penguins, it is flightless, with a streamlined body and wings stiffened and flattened into flippers for a marine habitat. Adults weigh an average of 2.2–3.5 kg (4.9–7.7 lb) and are 60–70 cm (24–28 in) tall. The species has distinctive pink patches of skin above the eyes and a black facial mask. The body's upper parts are black and sharply delineated from the white underparts, which are spotted and marked with a black band. 
+The African penguin is a pursuit diver and feeds primarily on fish and squid. Once extremely numerous, the African penguin is declining rapidly due to a combination of several threats and is classified as endangered. It is a charismatic species and is popular with tourists. Other vernacular names of the species include black-footed penguin and jackass penguin, due to the species' loud, donkey-like noise, although several related species of South Jackass penguins produce the same sound. They can be found along the coast of South Africa and Namibia.
+
+
+== Taxonomy ==
+In 1747 the English naturalist George Edwards included an illustration and a description of the African penguin in the second volume of his A Natural History of Uncommon Birds. He used the English name "The Black-Footed Penguins". Edwards based his hand-coloured etching on two preserved specimens that had been brought to London. He suspected that they had been collected near the Cape of Good Hope. When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he placed the African penguin with the wandering albatross in the genus Diomedea. Linnaeus included a brief description, coined the binomial name Diomedea demersa and cited Edwards' work. The African penguin is now placed with the banded penguins in the genus Spheniscus that was introduced in 1760 by the French zoologist Mathurin Jacques Brisson. The genus name Spheniscus is from Ancient Greek word σφήν (sphēn) meaning "wedge" and is a reference to the animal's thin, wedge-shaped flippers. The specific epithet demersus is Latin meaning "plunging" (from demergere meaning "to sink").Banded penguins are found mainly in the Southern Hemisphere with the Humboldt penguin and Magellanic penguins found in southern South America and the Galápagos penguin found in the Pacific Ocean near the equator. All are similar in shape, colour and behaviour.
+
+
+== Description ==
+
+African penguins grow to 60–70 cm (24–28 in) tall and weigh between 2.2–3.5 kg (4.9–7.7 lb). The beak length of the African penguin varies, usually growing between 20–30 cm (8-11 in). They have a black stripe and black spots on the chest, the pattern of which is unique to each penguin, like human fingerprints. The sweat glands above the eyes cool the birds' blood and as the temperature rises, increased blood flow causes the glands to get pinker. This species exhibits slight sexual dimorphism; the males are slightly larger than the females and have longer beaks. Juveniles do not possess the bold, delineated markings of the adult, but instead have dark upperparts that vary from greyish-blue to brown; the pale underparts lack both spots and the band. The beak is more pointed than that of the Humboldt penguin. The African penguin's colouring is a form of protective colouration known as countershading. The white undersides of the birds are difficult to spot by predators under the water and the penguins' black backs blend in with the water when viewed from above. 
+African penguins resemble and are thought to be related to the Humboldt, Magellanic and Galápagos penguins. African penguins have a very recognisable appearance, with a thick band of black that is in the shape of an upside-down horseshoe. They have black feet and black spots that vary in size and shape between individuals. Magellanic penguins share a similar bar marking that often confuses the two; the Magellanic has a double bar on the throat and chest, whereas the African has a single bar. These penguins have the nickname "jackass penguin", which comes from the loud penguin noises they make.
+
+
+== Distribution and habitat ==
+The African penguin is only found on the south-western coast of Africa, living in colonies on 24 islands between Namibia and Algoa Bay, near Port Elizabeth, South Africa. It is the only penguin species that breeds in Africa and its presence gave name to the Penguin Islands.
+
+Two colonies were established by penguins in the 1980s on the mainland near Cape Town, namely Boulders Beach near Simon's Town and Stony Point in Betty's Bay. Mainland colonies likely became possible only in recent times due to the reduction of predator numbers, although the Betty's Bay colony has been attacked by leopards. The only other mainland colony is in Namibia, but it is not known when it was established.
+Boulders Beach is a tourist attraction due to the beach, swimming and the penguins. The penguins will allow people to approach them as close as a meter.
+Breeding populations of African penguins are being kept in numerous zoos worldwide. No colonies are known outside the southwestern coast of Africa, although vagrants (mostly juveniles) may occasionally be sighted beyond the normal range.
+
+
+=== Population ===
+Roughly 4 million African penguins existed at the beginning of the 19th century. Of the 1.5 million African penguins estimated in 1910, only some 10% remained at the end of the 20th century. African penguin populations, which breed in Namibia and South Africa, have declined by 95% since pre-industrial times.Today, their breeding is largely restricted to 24 islands from Namibia to Algoa Bay, South Africa, with the Boulders Beach colony being an exception to this rule.
+The total population fell to approximately 150,000–180,000 in 2000. Of those, 56,000 belonged to the Dassen Island colony and 14,000 to the Robben Island colony. The colony at Dyer Island in South Africa fell from 46,000 in the early 1970s to 3,000 in 2008.In 2008, 5,000 breeding pairs were estimated to live in Namibia.
+In 2010, the total African penguin population was estimated at 55,000. At the rate of decline seen from 2000 to 2010, the African penguin is expected to be extinct in the wild by 2026.In 2012, about 18,700 breeding pairs were estimated to live in South Africa, with the majority on St. Croix Island in Algoa Bay.The total breeding population across both South Africa and Namibia fell to a historic low of about 20,850 pairs in 2019.
+
+
+== Behaviour ==
+
+
+=== Diet ===
+African penguins forage in the open sea, where they feed on pelagic fish such as sardines and anchovies (specifically the Southern African anchovy) and marine invertebrates such as squids and small crustaceans, primarily krills and shrimps. Penguins normally swim within 20 km (12 mi) of the shore. A penguin may consume up to 540 grams (1.19 lb) of prey every day, but this may increase to over 1 kg (2.2 lb) when raising older chicks.Due to the marked decline of sardines in the waters near its habitat, African penguins' diet has shifted towards anchovies to some extent, although available sardine biomass is still a notable determinant of penguin population development and breeding success. While a diet of anchovies appears to be generally sufficient for the penguins, it is not ideal due to anchovies' lower concentrations of fat and protein. The Penguin's diet changes throughout the year; as in many seabirds, it is believed that the interaction of diet choice and breeding success helps the penguins maintain their population size. Although parent penguins are protective of their chicks, they will not incur nutritional deficits themselves if food is scarce and hunting requires a greater time or energy commitment. This may lead to higher rates of brood loss under poor food conditions.
+When foraging, African penguins carry out dives that reach an average depth of 25 m (82 ft) and last for 69 seconds, although a maximum depth of 130 m (430 ft) and duration of 275 seconds has been recorded.
+
+
+=== Breeding ===
+
+The African penguin is monogamous; it breeds in colonies and pairs return to the same site each year. It has an extended breeding season, with nesting usually peaking from March to May in South Africa and November to December in Namibia. A clutch of two eggs are laid either in burrows burrowed in guano or nests in the sand under boulders or bushes. Incubation is undertaken equally by both parents for around 40 days. At least one parent guards the chicks for about one month, whereafter the chicks join a crèche with other chicks and both parents spend most of the day foraging in the sea.
+Chicks fledge at 60 to 130 days, the timing depending on environmental factors such as the quality and availability of food. The fledged chicks then go to sea on their own, where they spend the next one to nearly two years. They then return to their natal colony to moult into adult plumage.When penguins moult, they are unable to forage in the sea as their new feathers are not yet waterproof; therefore, they fast over the entire moulting period. African penguins typically take around three weeks to molt and lose about half of their body weight by burning up their fat reserves in the process.African penguins spend most of their lives at sea until it comes time for them to lay their eggs. Females remain fertile for about 10 years. Due to high predation on the mainland, African penguins will seek protection on offshore islands, where they are safer from larger mammals and natural challenges. These penguins usually breed during the winter when temperatures are cooler. African penguins often will abandon their eggs if they become overheated in the hot sun and abandoned eggs never survive the heat. The eggs are three to four times bigger than chicken eggs. Ideally, the eggs are incubated in a burrow dug into the guano layer (which provides suitable temperature regulation), but the widespread human removal of guano deposits has rendered this type of nest unfeasible in many colonies. To compensate, penguins burrow holes in the sand, nest under rocks or bushes or make use of nest boxes if they are provided. The penguins spend three weeks on land caring for their offspring, after which chicks may be left alone during the day while the parents forage. The chicks are frequently killed by predators or succumb to the hot sun. Parents usually feed hatchlings during dusk or dawn.
+In 2015, when foraging conditions were favourable, more male than female African penguin chicks were produced in the colony on Bird Island. Male chicks also had higher growth rates and fledging mass and therefore may have higher post-fledging survival than females. This, coupled with higher adult female mortality in this species, may result in a male-biased adult sex ratio and may indicate that conservation strategies focused on benefiting female African penguins may be necessary.
+
+
+=== Predation ===
+The average lifespan of an African penguin is 10 to around 25 years in the wild and up to 30 in captivity.The primary predators of African penguins at sea include sharks and fur seals. While nesting: kelp gulls, Cape genets, mongooses, caracals and domestic cats and dogs may prey on the penguins and their chicks. Mortality from terrestrial predators is higher if penguins are forced to breed in the open in the absence of suitable burrows or nest boxes.
+
+
+== Threats and conservation ==
+
+
+=== Historical exploitation ===
+African penguin eggs were considered a delicacy and were still being eaten and collected for sale as recently as the 1970s. In the 1950s, they were being collected from Dassen Island and sold in nearby towns. In 1953, 12,000 eggs were collected. In the late 1950s, some French chefs expressed interest in recipes including African penguin eggs collected from the islands off the west coast of South Africa and placed annual orders for small quantities. In the mid 1960s, eggs were collected in the thousands and sold by the dozen, with each customer limited to two dozen eggs in total.The practice of collecting African penguin eggs involved smashing those found a few days before a collecting effort to ensure that only freshly laid eggs were sold. This added to the drastic decline of the African penguin population around the Cape coast, a decline which was hastened by the removal of guano from islands for use as fertiliser, eliminating the burrowing material used by penguins.
+
+
+=== Oil spills ===
+Penguins remain susceptible to pollution of their habitat by petrochemicals from spills, shipwrecks and cleaning of tankers while at sea. Accounts of Africa penguins impacted by oil date back to the 1930s. African penguins' exposure to oil spills is both chronic (higher frequency small discharges of oil at sea) and acute (rare maritime disasters where large volumes of oil are released in a single event). Penguins of many species have been impacted by oil spills across the southern hemisphere.
+In 1948, the tanker Esso Wheeling sank, subsequently oiling and killing thousands of penguins of the Dyer Island colony. In 1953, dead penguins were among a range of dead birds, fish and other marine life that washed ashore after the tanker Sliedrecht was holed and spilled oil near Table Bay. In 1971, the SS Wafra oil spill impacted the African penguin colony of Dyer Island. In 1972, oil spilt following the Oswego-Guardian and Texanita collision oiled roughly 500 penguins. In 1975, newspapers reported that oil pollution from shipwrecks and the pumping of bilges at sea had killed tens of thousands of African penguins. At the time, the Dassen Island colony was being passed by 650 oil tankers each month because the Suez Canal had become blocked with wrecked vessels, thus increasing maritime traffic past the Cape of Good Hope.In 1979, an oil spill prompted the collection and treatment of 150 African penguins from St. Croix Island near Port Elizabeth. The animals were later released at Robben Island and four of them promptly swam back to St. Croix Island, surprising scientists.In 1983, the exposure of penguins of Dassen Island to the oil slick from the Castillo de Bellver was also a topic of concern given the penguins' conservation status at the time, but owing to the prevailing wind and current, only gannets were oiled.
+
+
+==== 1994 MV Apollo Sea disaster ====
+African penguin casualties were significant following the sinking of the MV Apollo Sea and a subsequent oil slick in 1994. 10,000 penguins were collected and cleaned, of which less than half survived.
+
+
+==== 2000 MV Treasure crisis ====
+Disaster struck on 23 June 2000, when the iron ore tanker MV Treasure sank between Robben Island and Dassen Island, South Africa. It released 400–1,000 tonnes (390–980 long tons; 440–1,100 short tons) of fuel oil, causing an unprecedented coastal bird crisis and oiling 19,000 adult penguins at the height of the best breeding season on record for this vulnerable species. The oiled birds were brought to an abandoned train repair warehouse in Cape Town to be cared for. An additional 19,500 un-oiled penguins were removed from Dassen Island and other areas before they became oiled and were released about 800 kilometres east of Cape Town. This gave workers enough time to clean up the oiled waters and shores before the birds could complete their long swim home (which took the penguins between one and three weeks). Some of the penguins were named and radio-tracked as they swam back to their breeding grounds. Tens of thousands of volunteers helped with the rescue and rehabilitation process, which was overseen by the International Fund for Animal Welfare (IFAW) and the South African Foundation for the Conservation of Coastal Birds (SANCCOB) and took more than three months to complete. This was the largest animal rescue event in history; more than 91% of the penguins were successfully rehabilitated and released – an amazing feat that could not have been accomplished without such a tremendous international response.Due to the positive outcome of African penguins being raised in captivity after tragedies such as the Treasure oil spill, the species is considered a good "candidate for a captive-breeding programme which aims to release offspring into the wild"; however, worry about the spread of new strains of avian malaria is a major concern in the situation.Bringing the birds inland led to the exposure of penguins to parasites and disease vector such as mosquitoes carrying avian malaria, which has caused 27% of the rehabilitated penguin deaths annually.
+
+
+==== 2016 & 2019 Port of Ngqura ====
+Small scale oil spills (of less than 400 litres (110 US gal)) have occurred at the Port of Ngqura since bunkering activities started there in 2016. Bunkering is a ship refuelling process that can result in oil spills and oil slicks entering the water. Hundreds of African penguins have been harmed following these spills due to the port's close proximity to penguin rookeries on St. Croix Island and seabird habitat on neighbouring Jahleel and Brenton Islands.
+
+
+=== Competition with fisheries ===
+Commercial fisheries of sardines and anchovy, the two main prey species of the penguins, have forced these penguins to search for prey farther offshore, as well as having to switch to eating less nutritious prey. Restricting commercial fishing near colony sites such as Robben Island for short periods (3 years) was shown to markedly improve penguin breeding success. Longer closure periods and closures near other colonies are being evaluated.
+
+
+=== Conservation status ===
+The African penguin is one of the species to which the African-Eurasian Waterbird Agreement (AEWA) applies. In September 2010, it was listed as endangered under the US Endangered Species Act. As of 2018, the African penguin is listed as endangered on the IUCN Red List. Its population is approximately 50,000 birds and declining.
+
+
+=== Mediation efforts ===
+Many organisations such as: SANCCOB, Dyer Island Conservation Trust, SAMREC and Raggy Charters with the Penguin Research Fund in Port Elizabeth are working to halt the decline of the African penguin. Measures include: monitoring population trends, hand-rearing and releasing abandoned chicks, establishing artificial nests and proclaiming marine reserves in which fishing is prohibited. Some colonies (such as on Dyer Island) are suspected to be under heavy pressure from predation by Cape fur seals and may benefit from the culling of individual problem animals, which has been found effective (although requiring a large amount of management effort) in trials.Established in 1968, SANCCOB is currently the only organisation mandated by the South African government to respond to crises involving seabirds along South Africa's coastline and is internationally recognised for the role it played during the MV Treasure oil spill. A modelling exercise conducted in 2003 by the University of Cape Town's FitzPatrick Institute of African Ornithology found that rehabilitating oiled African penguins has resulted in the current population being 19% larger than it would have been in the absence of SANCCOB's rehabilitation efforts.In February 2015, the Dyer Island Conservation Trust opened the African Penguin and Seabird Sanctuary (APSS) in Gansbaai, South Africa. The centre was opened by then-Department of Tourism minister Derek Hanekom and will serve as a hub for seabird research carried out by the Dyer Island Conservation Trust. The centre will also run local education projects, host international marine volunteers and seek to improve seabird handling techniques and rehabilitation protocols.
+
+
+== Captivity ==
+
+African penguins are a commonly seen species in zoos across the world. Because they do not require particularly low temperatures, they are often kept in outside enclosures. They adapt fairly well to this captive environment and are rather easy to breed compared to other species of the family. In Europe, the breeding programme EAZA is regulated by Artis Royal Zoo in the Netherlands, whilst in the United States the SSP programme is cooperatively managed by the AZA. The idea is to create a backup captive population, as well as to aid in the conservation of the population in its natural habitat. Between 2010 and 2013, American zoos spent $300,000 on in situ (wild population) conservation.

+The leopard tortoise (Stigmochelys pardalis) is a large and attractively marked tortoise found in the savannas of eastern and southern Africa, from Sudan to the southern Cape. It is the only extant member of the genus Stigmochelys, although in the past, it was commonly placed in Geochelone. This tortoise is a grazing species that favors semiarid, thorny to grassland habitats. In both very hot and very cold weather, it may dwell in abandoned fox, jackal, or aardvark holes. The leopard tortoise does not dig other than to make nests in which to lay eggs. Given its propensity for grassland habitats, it grazes extensively upon mixed grasses. It also favors succulents and thistles.
+
+
+== Taxonomy and etymology ==
+The phylogenic placement of the leopard tortoise has been subject to several revisions. Different authors have placed it in Geochelone (1957), Stigmochelys (2001), Centrochelys (2002), and Psammobates (2006). More recently, consensus appears to have settled on Stigmochelys, a monotypic genus. Considerable debate has occurred about the existence of two subspecies, S. p. pardalis and S. p. babcocki, but recent work does not support this distinction.Stigmochelys is a combination of Greek words: stigma meaning "mark" or "point" and chelone meaning "tortoise". The specific name pardalis is from the Latin word pardus meaning "leopard" and refers to the leopard-like spots on the tortoise's shell.
+
+
+== Description ==
+
+The leopard tortoise is the fourth-largest species of tortoise in the world, with typical adults reaching 40 cm (16 in) and weighing 13 kg (29 lb). Adults tend to be larger in the northern and southern ends of their range, where typical specimens weigh up to 20 kg (44 lb), and an exceptionally large tortoise may reach 70 cm (28 in) and weigh 40 kg (88 lb).The carapace is high and domed with steep, almost vertical sides. Juveniles and young adults are attractively marked with black blotches, spots, or even dashes and stripes on a yellow background. In mature adults, the markings tend to fade to a nondescript brown or grey. The head and limbs are uniformly colored yellow, tan, or brown.
+
+
+== Distribution and habitat ==
+They are widely distributed across the arid and savanna regions of eastern and southern Africa, extending from South Sudan and Somalia, across East Africa, to South Africa and Namibia. The species is generally absent from the humid forest regions of Central Africa. Over this range, the leopard tortoise occupies the most varied habitats of any African tortoise, including grasslands, thorn-scrub, mesic brushland, and savannas. They can be found at altitudes ranging from sea level to 2,900 m (9,500 ft).
+
+
+== Ecology and behavior ==
+
+Leopard tortoises are herbivorous; their diet consists of a wide variety of plants including forbs, thistles, grasses, and succulents. They sometimes gnaw on bones or even hyena feces to obtain calcium, necessary for bone development and their eggshells. Seeds can pass undigested through the gut, so the leopard tortoise plays a significant role in seed dispersal. Normally active during the day, they are less active during hot weather or during the dry season.The leopard tortoise reaches sexual maturity between  12 and 15 years old, and may live as long as 80 to 100 years. During the mating season, males fight over females, ramming and butting their competitors. They trail after females for quite some distance, often ramming them into submission. When mating, the male makes grunting vocalizations. Nesting occurs between May and October when the female digs a hole and lays a clutch of five to 30 eggs. As many as five to seven clutches may be laid in a single season. Incubation  takes 8–15 months depending on temperature.  The numerous predators of the eggs and hatchlings include monitor lizards, snakes, jackals, and crows. Adults have few natural predators, but lions and hyenas have occasionally been reported preying on them.
+
+
+== Conservation ==
+The leopard tortoise is a widespread species and remains common throughout most of its range. Human activities, including agricultural burning, consumption, and especially commercial exploitation in the pet trade, are potential threats, but have not yet caused significant population declines. They are increasingly being bred in captivity for the pet trade. For example, most tortoises exported from Kenya and Tanzania originate in captive-breeding programs, alleviating collection from the wild.The leopard tortoise has been listed in Appendix II of CITES since 1975, and in 2000, the United States banned their import because of the risk posed by heartwater, an infectious disease carried by tortoise ticks that could seriously impact the US livestock industry.

+The meerkat (Suricata suricatta) or suricate is a small mongoose found in southern Africa. It is characterised by a broad head, large eyes, a pointed snout, long legs, a thin tapering tail, and a brindled coat pattern. The head-and-body length is around 24–35 cm (9.4–13.8 in), and the weight is typically between 0.62 and 0.97 kg (1.4 and 2.1 lb). The coat is light grey to yellowish-brown with alternate, poorly-defined light and dark bands on the back. Meerkats have foreclaws adapted for digging and have the ability to thermoregulate to survive in their harsh, dry habitat. Three subspecies are recognised.
+Meerkats are highly social, and form packs of two to 30 individuals each that occupy home ranges around 5 km2 (1.9 sq mi) in area. There is a social hierarchy—generally dominant individuals in a pack breed and produce offspring, and the nonbreeding, subordinate members provide altruistic care to the pups. Breeding occurs around the year, with peaks during heavy rainfall; after a gestation of 60 to 70 days, a litter of three to seven pups is born.
+They live in rock crevices in stony, often calcareous areas, and in large burrow systems in plains. The burrow systems, typically 5 m (16 ft) in diameter with around 15 openings, are large underground networks consisting of two to three levels of tunnels. These tunnels are around 7.5 cm (3.0 in) high at the top and wider below, and extend up to 1.5 m (4 ft 11 in) into the ground. Burrows have moderated internal temperatures and provide a comfortable microclimate that protects meerkats in harsh weather and at extreme temperatures.
+Meerkats are active during the day, mostly in the early morning and late afternoon; they remain continually alert and retreat to burrows when sensing danger. They use a broad variety of calls to communicate among one another for different purposes, for example to raise an alarm on sighting a predator. Primarily insectivorous, meerkats feed heavily on beetles and lepidopterans, arthropods, amphibians, small birds, reptiles, and plant material in their diet.
+Commonly living in arid, open habitats with little woody vegetation, meerkats occur in southwestern Botswana, western and southern Namibia, northern and western South Africa; the range barely extends into southwestern Angola. With no significant threats to the population, the meerkat is listed as Least Concern on the IUCN Red List. Meerkats are widely depicted in television, movies and other media.
+
+
+== Etymology ==
+The word 'meerkat' derives from the Dutch name for a kind of monkey, which in turn comes from the Old High German mericazza, possibly as a combination of meer ('lake') and kat ('cat'). This may be related to the similar Hindi: मर्कट (markat, or monkey), deriving from Sanskrit, though the Germanic origin of the word predates any known connections to India. The name was used for small mammals in South Africa from 1801 onward, possibly because the Dutch colonialists used the name in reference to many burrowing animals. The native South African name for the meerkat is 'suricate', possibly deriving from the French: surikate, which in turn may have a Dutch origin. In Afrikaans the meerkat is called graatjiemeerkat or stokstertmeerkat; the term mierkatte or meerkatte can refer to both the meerkat and the yellow mongoose (Afrikaans: rooimeerkat). In colloquial Afrikaans mier means 'ant' and kat means 'cat', hence the name probably refers to the meerkat's association with termite mounds.
+
+
+== Taxonomy ==
+
+In 1776, Johann Christian Daniel von Schreber described a meerkat from the Cape of Good Hope, giving it the scientific name Viverra suricatta. The generic name Suricata was proposed by Anselme Gaëtan Desmarest in 1804, who also described a zoological specimen from the Cape of Good Hope. The present scientific name Suricata suricatta was first used by Oldfield Thomas and Harold Schwann in 1905 when they described a specimen collected at Wakkerstroom. They suggested there were four local meerkat races in the Cape and Deelfontein, Grahamstown, Orange River Colony and southern Transvaal, and Klipfontein respectively. Several zoological specimens were described between the late 18th and 20th centuries, of which three are recognised as valid subspecies:
+S. s. suricatta (Schreber, 1776) occurs in southern Namibia, southern Botswana, and South Africa.
+S. s. majoriae Bradfield, 1936 occurs in central and northwestern Namibia.
+S. s. iona Crawford-Cabral, 1971 occurs in southwestern Angola.
+
+
+== Phylogeny and evolution ==
+Meerkat fossils dating back to 2.59 to 0.01 million years ago have been excavated in various locations in South Africa. A 2009 phylogenetic study of the family Herpestidae split into two lineages around the Early Miocene (25.4–18.2 mya)—eusocial and solitary mongooses. The meerkat belongs to the monophyletic eusocial mongoose clade along with several other African mongooses: Crossarchus (kusimanse), Helogale (dwarf mongoose), Liberiictis (Liberian mongoose) and Mungos (banded mongoose). The solitary mongoose lineage comprises two clades including species such as Meller's mongoose (Rhynchogale melleri) and the yellow mongoose (Cynictis penicillata). The meerkat genetically diverged from the rest of the clade 22.6–15.6 mya. The phylogenetic relationships of the meerkat are depicted as follows:
+
+
+== Characteristics ==
+
+The meerkat is a small mongoose of slim build characterised by a broad head, large eyes, a pointed snout, long legs, a thin tapering tail and a brindled coat pattern. It is smaller than most other mongooses except the dwarf mongooses (genus Helogale) and possibly Galerella species. The head-and-body length is around 24–35 cm (9.4–13.8 in), and the weight has been recorded to be between 0.62–0.97 kg (1.4–2.1 lb) without much variation between the sexes (though some dominant females can be heavier than the rest). The soft coat is light grey to yellowish brown with alternate, poorly-defined light and dark bands on the back. Individuals from the southern part of the range tend to be darker. The guard hairs, light at the base, have two dark rings and are tipped with black or silvery white; several such hairs aligned together give rise to the coat pattern. These hairs are typically between 1.5 and 2 cm (0.59 and 0.79 in), but measure 3–4 cm (1.2–1.6 in) on the flanks. Its head is mostly white and the underparts are covered sparsely with dark reddish-brown fur, with the dark skin underneath showing through. The eyes, in sockets covering over 20% of the skull length, are capable of binocular vision. The slim, yellowish tail, unlike the bushy tails of many other mongooses, measures 17 to 25 cm (6.7 to 9.8 in), and is tipped with black. Females have six nipples. The meerkat looks similar to two sympatric species—the banded and the yellow mongooses. The meerkat can be told apart from the banded mongoose by its smaller size, shorter tail and bigger eyes relative to the head; the yellow mongoose differs in having a bushy tail and lighter coat with an inner layer of yellow fur under the normal brown fur.The meerkat has 36 teeth with the dental formula of 3.1.3.23.1.3.2. It is well adapted for digging, movement through tunnels and standing erect, though it is not as capable of running and climbing. The big, sharp and curved foreclaws (slightly longer than the hindclaws) are highly specialised among the feliforms, and enable the meerkat to dig efficiently. The black, crescent-like ears can be closed to prevent the entry of dirt and debris while digging. The tail is used to balance when standing upright. Digitigrade, the meerkat has four digits on each foot with thick pads underneath.The meerkat has a specialised thermoregulation system that helps it survive in its harsh desert habitat. A study showed that its body temperature follows a diurnal rhythm, averaging 38.3 °C (100.9 °F) during the day and 36.3 °C (97.3 °F) at night. As the body temperature falls below the thermoneutral zone, determined to be 30–32.5 °C (86.0–90.5 °F), the heart rate and oxygen consumption plummet; perspiration increases sharply at temperatures above this range. Additionally, it has a basal metabolic rate remarkably lower than other carnivores, which helps in conserving water, surviving on lower amounts of food and decreasing heat output from metabolic processes. During winter, it balances heat loss by increasing the metabolic heat generation and other methods such as sunbathing.
+
+
+== Ecology and behaviour ==
+
+The meerkat is a social mammal, forming packs of two to 30 individuals each comprising nearly equal numbers of either sex and multiple family units of pairs and their offspring. Members of a pack take turns at jobs such as looking after pups and keeping a lookout for predators. Meerkats are a cooperatively breeding species—typically the dominant 'breeders' in a pack produce offspring, and the nonbreeding, subordinate 'helpers' provide altruistic care for the pups. This division of labour is not as strictly defined as it is in specialised eusocial species, such as the breeder-worker distinction in ants. Moreover, meerkats have a clear dominance hierarchy with older individuals having a higher social status. A study showed that dominant individuals can contribute more to offspring care when fewer helpers were available; subordinate members increased their contributions if they could forage better.Packs live in rock crevices in stony areas and in large burrow systems in plains. A pack generally occupies a home range, 5 km2 (1.9 sq mi) large on average but sometimes as big as 15 km2 (5.8 sq mi), containing many burrows 50 to 100 m (160 to 330 ft) apart, of which some remain unused. A 2019 study showed that large burrows towards the centre of a range are preferred over smaller ones located near the periphery; this was especially the case with packs that had pups to raise. A pack may shift to another burrow if the dominant female has little success finding prey in an area. The area near the periphery of home ranges is scent marked mostly by the dominant individuals; there are communal latrines, 1 km2 (0.39 sq mi) large, close to the burrows. Packs can migrate collectively in search of food, to escape high predator pressure and during floods.Meerkats are highly vigilant, and frequently survey their surroundings by turning their heads side to side; some individuals always stand sentry and look out for danger. Vocal communication is used frequently in different contexts; for instance repetitive, high-pitched barks are used to warn others of predators nearby. They will generally retreat to their burrows for safety, where they will remain until the danger is gone. They stick their heads out of burrows to check the area outside, still barking. Mobs of meerkats fiercely attack snakes that may come near them. Raptors such as bateleurs, martial eagles, tawny eagles, and pale chanting goshawks are major aerial predators; on the ground, meerkats may be threatened by bat-eared foxes, black-backed jackals, and Cape foxes.
+
+
+=== Social behaviour ===
+Encounters between members of different packs are highly aggressive, leading to severe injuries and often deaths; 19% of meerkats die by conspecific violence, which is the highest recorded percentage among mammals. Females, often the heaviest ones, try to achieve dominance over the rest in many ways such as fierce competition or taking over from the leader of the pack. A study showed that females who grew faster were more likely to assert dominance, though males did not show such a trend. Males seeking dominance over groups tend to scent mark extensively and are not submissive; they often drive out older males in a group and take over the pack themselves. Subordinate individuals face difficulties in breeding successfully; for instance, dominant females often kill the litters of subordinate ones. As such, subordinate individuals might disperse to other packs to find mates during the breeding season. Some subordinate meerkats will even kill the pups of dominant members in order to improve their own offspring's position. It can take days for emigrants to secure entry into other packs, and they often face aversion from the members. Males typically succeed in joining existing groups; they often inspect other packs and their burrow systems in search of breeding opportunities. Many often team up in 'coalitions' for as long as two months and travel nearly 5 km (3.1 mi) a day on twisted paths. Dispersal appears to be less common in females, possibly because continuing to stay within a pack can eventually win them dominance over other members. Dispersed females travel longer than coalitions, and tend to start groups of their own or join other similar females; they aim for groups of emigrant males or those without a breeding female. Subordinate females, unlike subordinate males, might be ousted from their packs, especially in the latter part of the dominant female's pregnancy, though they may be allowed to return after the birth of the pups.
+
+
+=== Burrowing ===
+
+Meerkat burrows are typically 5 m (16 ft) in diameter with around 15 openings, though one of dimensions 25 by 32 m (82 by 105 ft) with as many as 90 holes has been reported. These large underground networks comprise two to three levels of tunnels up to 1.5 m (4 ft 11 in) into the ground; the tunnels, around 7.5 cm (3.0 in) high at the top, become broader after descending around a metre. The entrances, 15 cm (5.9 in) in diameter, are created by digging at an angle of 40 degrees to the surface; the soil accumulated as a result can slightly increase the height of burrow sites. 'Boltholes' are used for a quick escape if dangers are detected. While constructing or renovating burrows meerkats will line up to form a continuous head-to-tail chain, break the soil into crumbs with their foreclaws, scoop it out with their forepaws joined and throw it behind them between their hindlegs.Outside temperatures are not reflected at once within burrows; instead there is usually an eight-hour lag which creates a temperature gradient in warrens, so that burrows are coolest in daytime and warmest at night. Temperatures inside burrows typically vary between 21 and 39 °C (70 and 102 °F) in summer and −4 and 26 °C (25 and 79 °F) in winter; temperatures at greater depths vary to a much lesser extent, with summer temperatures around 22.6 to 23.2 °C (72.7 to 73.8 °F) and winter temperatures around 10 to 10.8 °C (50.0 to 51.4 °F). This reduces the need for meerkats to thermoregulate individually by providing a comfortable microclimate within burrows; moreover, burrowing protects meerkats in harsh weather and at extreme temperatures. Consequently, meerkats spend considerable time in burrows; they are active mainly during the day and return to burrows after dark and often to escape the heat of the afternoon. Activity peaks during the early morning and late afternoon. Meerkats huddle together to sleep in compact groups, sunbathe and recline on warm rocks or damp soil to adjust their body temperatures.Meerkats tend to occupy the burrows of other small mammals more than constructing them on their own; they generally share burrows with Cape ground squirrels and yellow mongooses. Cape ground squirrels and meerkats usually do not fight for space or food. Though yellow mongooses are also insectivores like meerkats, competition for prey is minimal as yellow mongooses are less selective in their diet. This association is beneficial to all the species as it saves time and efforts spent in making separate warrens. Many other species have also been recorded in the meerkat burrows, including African pygmy mice, Cape grey mongooses, four-striped grass mice, Highveld gerbils, rock hyraxes, slender mongooses, South African springhares and white-tailed rats.
+
+
+=== Vocalisations ===
+
+Meerkats have a broad vocal repertoire that they use to communicate among one another in several contexts; many of these calls may be combined by repetition of the same call or mixing different sounds. A study recorded 12 different types of call combinations used in different situations such as guarding against predators, caring for young, digging, sunbathing, huddling together and aggression.Short-range 'close calls' are produced while foraging and after scanning the vicinity for predators. 'Recruitment calls' can be produced to collect meerkats on sighting a snake or to investigate excrement or hair samples of predators or unfamiliar meerkats. 'Alarm calls' are given out on detecting predators. All these calls differ in their acoustic characteristics, and can evoke different responses in the 'receivers' (meerkats who hear the call); generally the greater the urgency of the scenario in which the call is given, the stronger is the response in the receivers.This indicates that meerkats are able to perceive the nature of the risk and the degree of urgency from the acoustics of a call, transmit it and respond accordingly. For instance, upon hearing a terrestrial predator alarm call, meerkats are most likely to scan the area and move towards the source of the call, while an aerial predator alarm call would most likely cause them to crouch down. A recruitment call would cause receivers to raise their tails (and often their hair) and move slowly towards the source.The complexity of calls produced by different mongooses varies by their social structure and ecology. For instance eusocial mongooses such as meerkats and banded mongooses use calls in a greater variety of contexts than do the solitary slender mongooses. Moreover, meerkats have more call types than do banded mongooses. Meerkat calls carry information to identify the signaling individual or pack, but meerkats do not appear to differentiate between calls from different sources. The calls of banded mongooses also carry a 'vocal signature' to identify the caller.
+
+
+=== Diet ===
+
+The meerkat is primarily an insectivore, feeding heavily on beetles and lepidopterans; it can additionally feed on eggs, amphibians, arthropods (such as scorpions, to whose venom they are immune), reptiles, small birds (such as the southern anteater-chat), plants and seeds. Captive meerkats include plenty of fruits and vegetables in their diet, and also kill small mammals by biting the backs of their skulls. They have also been observed feeding on the desert truffle Kalaharituber pfeilii. Meerkats often eat citron melons and dig out roots and tubers for their water content.Mongooses spend nearly five to eight hours foraging every day. Like other social mongooses, meerkats in a pack will disperse within 5 m (16 ft) of one another and browse systematically in areas within their home range without losing visual or vocal contact. Some individuals stand sentry while the rest are busy foraging. Meerkats return to an area only after a week of the last visit so that the food supply is replenished sufficiently. They hunt by scent, and often dig out soil or turn over stones to uncover hidden prey. Meerkats typically do not give chase to their prey, though they may pursue geckos and lizards over several metres. Food intake is typically low during winter.
+
+
+=== Reproduction ===
+
+Meerkats breed throughout the year with seasonal peaks, typically during months of heavy rainfall; for instance, maximum births occur from January to March in the southern Kalahari. Generally only dominant individuals breed, though subordinate members can also mate in highly productive years. Females become sexually mature at two to three years of age. Dominant females can have up to four litters annually (lesser for subordinate females), and the number depends on the amount of precipitation. Mating behaviour has been studied in captive individuals. Courtship behaviour is limited; the male fights with his partner, getting hold of her by her snout. He will grip the nape of her neck if she resists mounting, and hold her down by grasping her flanks during copulation.After a gestation of 60 to 70 days, a litter of three to seven pups is born. Pups weigh around 100 g (3.5 oz) in the first few days of birth; the average growth rate for the first three months is 4.5 g (0.16 oz) per day, typically the fastest in the first month. A 2019 study showed that growth and survival rates of pups might decrease with increase in temperature.Infants make continuous sounds that resemble bird-like tweets, that change to a shrill contact call as they grow older. Young pups are kept securely in a den, from where they emerge after around 16 days, and start foraging with adults by 26 days. The nonbreeding members of the pack help substantially with juvenile care, for instance they feed the pups and huddle with them for warmth. A study showed that nearly half of the litters of dominant females, especially those born later in the breeding season were nursed by subordinate females, mostly those that were or recently had been pregnant.Sex biases have been observed in feeding; for instance, female helpers feed female pups more than male pups unlike male helpers who feed both equally. This is possibly because the survival of female pups is more beneficial to female helpers as females are more likely to remain in their natal pack. Some helpers contribute to all activities more than others, though none of them might be specialised in any of them. Sometimes helpers favour their own needs over those of pups and decide not to feed them; this behaviour, known as "false-feeding", is more common when the prey is more valued by the meerkat.The father remains on guard and protects his offspring, while the mother spends a lot of time foraging to produce enough milk for her young. Mothers give out shrill, repetitive calls to ensure their pups follow them and remain close together. Unable to forage themselves, young pups vocalise often seeking food from their carers. Like many species, meerkat pups learn by observing and mimicking adult behaviour, though adults also engage in active instruction. For example, meerkat adults teach their pups how to eat a venomous scorpion by removing the stinger and showing the pups how to handle the creature. The mother runs around with prey in her mouth, prompting her pups to catch it. Pups become independent enough to forage at around 12 weeks of age. Meerkats are estimated to survive for five to 15 years in the wild; the maximum lifespan recorded in captivity is 20.6 years.Females appear to be able to discriminate the odour of their kin from that of others. Kin recognition is a useful ability that facilitates cooperation among relatives and the avoidance of inbreeding. When mating occurs between meerkat relatives it often results in negative fitness consequences (inbreeding depression), that affect a variety of traits such as pup mass at emergence from the natal burrow, hindleg length, growth until independence and juvenile survival. These negative effects are likely due to the increased homozygosity or higher genetic similarity among individuals that arise from inbreeding and the consequent expression of deleterious recessive mutations.
+
+
+== Distribution and habitat ==
+
+The meerkat occurs in southwestern Botswana, western and southern Namibia, northern and western South Africa; the range barely extends into southwestern Angola. It lives in areas with stony, often calcareous ground in a variety of arid, open habitats with little woody vegetation. It is common in savannahs, open plains and rocky areas beside dry rivers in biomes such as the Fynbos and the Karoo, where the mean yearly rainfall is below 600 mm (24 in). The average precipitation reduces to 100 to 400 mm (3.9 to 15.7 in) towards the northwestern areas of the range. It prefers areas with short grasses and shrubs common in velds, such as camelthorn in Namibia and Acacia in the Kalahari. It is absent from true deserts, montane regions and forests. Population densities vary greatly between places, and are significantly influenced by predators and rainfall. For instance, a study in the Kgalagadi Transfrontier Park, where predation pressure is high, recorded a lower mean meerkat density relative to a ranch with lower occurrence of predators; in response to a 10% decrease in rainfall over a year, the density fell from 0.95 to 0.32/km2 (2.46 to 0.83/sq mi).
+
+
+== Threats and conservation ==
+
+The meerkat is listed as Least Concern on the IUCN Red List; the population trend appears to be stable. There are no significant threats except low rainfall, which can lead to deaths of entire packs. Research has shown that temperature extremes have negative impacts on Kalahari Desert meerkats. Increased maximum air temperature is correlated with decreased survival and body mass in pups, perhaps as a result of dehydration from water loss during evaporative cooling or decreased water content in food, or from the heavier metabolic costs of thermoregulation on hot days. Higher temperatures are also associated with increased rates of endemic tuberculosis infection; this may be due to decreased immune function resulting from physiological stress, as well as increased male emigration rates observed during heat waves.Meerkats occur in several protected areas such as the Kgalagadi Transfrontier Park and the Makgadikgadi Pan. The Kalahari Meerkat Project, founded by Tim Clutton-Brock, is a long-term research project run by four different research groups that focuses on understanding cooperative behaviour in meerkats. It began in the Gemsbok National Park but was shifted to the Kuruman River Reserve in 1993.
+
+
+== Interactions with humans ==
+
+Meerkats are generally tame animals. However, they are unsuitable as a pet as they can be aggressive and have a strong, ferret-like odour. In South Africa meerkats are used to kill rodents in rural households and lepidopterans in farmlands. Meerkats can transmit rabies to humans, but yellow mongooses appear to be more common vectors. It has been suggested that meerkats may even limit the spread of rabies by driving out yellow mongooses from their burrows; meerkats are generally not persecuted given their economic significance in crop protection, though they may be killed due to rabies control measures to eliminate yellow mongooses. Meerkats can also spread tick-borne diseases.Meerkats have been widely portrayed in movies, television and other media. A popular example is Timon from the Lion King franchise, who is an anthropomorphic meerkat. Meerkat Manor (2005–2008), a television programme produced by Oxford Scientific Films that was aired on Animal Planet, focused on groups of meerkats in the Kalahari that were being studied in the Kalahari Meerkat Project.

+The siamang (, also UK: ; Symphalangus syndactylus) is an arboreal, black-furred gibbon native to the forests of Indonesia, Malaysia, and Thailand. The largest of the gibbons, the siamang can be twice the size of other gibbons, reaching 1 m (3.3 ft) in height, and weighing up to 14 kg (31 lb). It is the only species in the genus Symphalangus. Fossils of siamangs dates back to the Middle Pleistocene.Two features distinguish the siamang from other gibbons. First, two digits on each foot—the second and third toes—are partially joined by a membrane, hence the specific name syndactylus, from the Ancient Greek σύν, sun-, "with" + δάκτυλος, daktulos, "finger". Second, a large gular sac (throat pouch), found in both males and females of the species, can be inflated to the size of the siamang's head, allowing it to make loud, resonating calls or songs.
+Two subspecies of the siamang may exist. If so, they are the nominate Sumatran siamang (S. s. syndactylus) and the Malaysian siamang (S. s. continentis, in Malay peninsula). Otherwise, the Malaysian individuals are only a population. The siamang occurs sympatrically with other gibbons; its two ranges are entirely within the combined ranges of the agile gibbon and the lar gibbon.
+The siamang can live to around 40 years in captivity.While the illegal pet trade takes a toll on wild populations, the principal threat to the siamang is habitat loss in both Indonesia and Malaysia. The palm oil production industry is clearing large swaths of forest, reducing the habitat of the siamang, along with those of other species, such as the Sumatran tiger.
+
+
+== Description ==
+
+The siamang has long, dense, shaggy hair, which is the darkest shade of all gibbons. The ape's long, gangling arms are longer than its legs. The average length of a siamang is 90 cm; the largest they have ever grown is 150 cm. The face of this large gibbon is mostly hairless, apart from a thin mustache.
+
+
+== Distribution and habitat ==
+The siamang inhabits the forest remnants of Sumatra Island and the Malay Peninsula, and is widely distributed from lowland forest to mountain forest—even rainforest—and can be found at altitudes up to 3800 m. It lives in groups of up to six individuals (four individuals on average) with an average home range of 23 hectares. Their day ranges are substantially smaller than those of sympatric Hylobates species, often less than 1 km. The siamang's melodious singing breaks the forest's silence in the early morning after the agile gibbons' or lar gibbons' calls. The siamangs in Sumatra and the Malay Peninsula are similar in appearance, but some behaviors differ between the two populations.
+
+
+== Ecology and behaviour ==
+
+
+=== Diet ===
+The siamang eats mainly various parts of plants. The Sumatran siamang is more frugivorous than its Malayan relative, with fruit making up to 60% of its diet. The siamang eats at least 160 species of plants, from vines to woody plants. Its major food source is figs (Ficus spp. The siamang prefers to eat ripe rather than unripe fruit, and young rather than old leaves. It eats flowers and a few animals, mostly insects. When the siamang eats large flowers, it eats only the corollae (petals), but it eats all parts of smaller flowers, with the small fruit collected in its hand before being consumed. When it eats big and hard seeds or seeds with sharp edges, it peels out the fruit flesh and throws away the seed. Although its diet consists of substantial portions of fruit, it is the most folivorous of all members of Hylobatidae. As it is also the largest gibbon, it fits well with the general primate dietary trend in which larger primates tend to be more folivorous.
+
+
+=== Demography and population ===
+A group of siamangs normally consists of an adult dominant male, an adult dominant female, with offspring, infants, and sometimes a subadult. The subadult usually leaves the group after attaining the age of 6–8 years; subadult females tend to leave the group earlier than subadult males. Siamang gestation period is between 6.2 and 7.9 months; after the infant is born, the mother takes care of the infant for the first year of its life. Siamang males tend to offer more paternal care than do other members of the family Hylobatidae, taking up a major role in carrying an infant after it is about 8 months old. The infant typically returns to its mother to sleep and nurse. The infant begins to travel independently from its parents by its third year of life.Siamangs are generally known to have monogamous mating pairs, which have been documented to spend more time in close proximity to each other, in comparison to other gibbon species. Both monogamous and polyandrous groups, though, are found in South Sumatra. In studying these populations, infants belonging to monogamous groups were found to receive more overall male care than infants in the polyandrous groups. This reduced care is most likely due to reduced certainty of paternity in these groups.Habitat disturbance affects siamang group composition; it is varied in age-sex structure between intact forest and burnt, regrown forest. The burnt, regrown forest population contained more adult and subadults than the intact forest population, which had more infants, small juveniles, and large juveniles. Infant survival rates in burnt, regrown forest groups are lower than in intact forest groups. The number of individuals in the latter is higher than in the former. The siamang in disturbed forests live in small groups and have a density lower than in intact forests because of lack of food resources and trees for living.
+In the 1980s, the Indonesian population of the siamang in the wild was estimated to be 360,000 individuals. This figure may be less in the 21st century: Bukit Barisan Selatan National Park is the third-largest protected area (3,568 km2) in Sumatra, of which roughly 2,570 km2 remain under forest cover inhabited by 22,390 siamangs (in 2002 censuses). In Sumatra, the siamang prefers to inhabit lowland forest between 500 and 1000 m above sea level.
+
+
+=== Behaviour ===
+The siamang tends to rest for more than half of its waking period from dawn to dusk, followed by feeding, moving, foraging, and social activities. It takes more rest during midday, taking time to groom others or to play. During resting time, it usually uses a branch of a large tree, lying on its back or belly. Feeding behaviors, foraging, and moving are most often in the morning and after resting. Grooming is one of the most important social interactions among family members. Grooming takes place between adults earlier in the day; the adults groom the juveniles later in the day. Adult males are the most involved in grooming.
+
+In the dry season, the size of the siamang's daily range is larger than in the rainy season. The siamang in southern Sumatra spends less time foraging than siamangs in other places, as it eats a diet higher in fruit. It thus  consumes more nutrients, which results in less time needed for food acquisition. A siamang may spend an entire day in a single fruiting tree, moving out when it wants to rest and returning to feed.Siamangs are a very social species of primates and exhibit a variety of tactile and visual gestures, along with actions and facial expressions to communicate and increase social bonds within their family group. They are also territorial, and interact with other family groups by making loud calls to let other groups know where their territory is. The calls may be asynchronous, where they are not directed at a particular neighbouring group, or simultaneous group calls may take place across the territory boundary. Males are known to chase one another across the boundary.
+Grooming frequency between males and females has been found to correlate to copulation frequency, as well as bouts of aggression. Pairs copulate over four to five months at intervals of two to three years. The peak of their reproductive activity is often during the time when fruit is most abundant. Dorsoventral copulation is the most common type in siamangs, where the female is squatting and the male hangs by his arms and grips the female with his legs, whereas ventroventral copulation, where both primates are suspended, occurs only one in 60 times on average.
+
+
+=== Role of calling ===
+
+The siamang starts its day by calling in the early morning; it calls less after midday, with the peak of the calls around 9:00 to 10:00 am. Most of the siamang's calls are directed to its neighbours rather than to those inside its home range. This means the siamang's calling is in response to disturbances and to defend its territory. Calls in the late morning typically happen when it meets or sees another siamang group. The edge of the siamang's home range, which may overlap another, is often the place where calling is made. Counter (co-response) calling occasionally happens near the border or in the overlap area. Calls are numerous when fruit is more abundant rather than when it is less available. Branch shaking, swinging, and moving around the tree crowns accompany the calling. This movement might be to show the other groups where they are.
+The siamang prefers calling in the living, tall, and big trees, possibly where another group is easy to see. Besides that, such trees can support siamang movement. Calling trees are usually near feeding trees, but sometimes they call in the feeding trees.Mated pairs produce loud, well-patterned calling bouts, which are referred to as duetting. These calls advertise the presence and status of a mated pair. Newly formed pairs spend more time singing than an established pair. Advertising the presence of a strong bond is advantageous in territorial defense. Siamang duetting differs from other species because it has a particularly complex vocal structure. Four distinct classes of vocalizations have been documented: booms, barks, ululating screams, and bitonal screams. Females typically produce long barks and males generally produce bitonal screams, but both sexes have been known to produce all four classes of vocalizations.
+
+
+=== Seeding ===
+As a frugivorous animal, the siamang disperses seeds through defecation as it travels across its territory. The siamang can carry seed while digesting, and defecate between 81.9 and 365.9 m (269 and 1,200 ft) from the seed resource, which supports the forest's regeneration and succession.
+
+
+== Threats and conservation ==
+As an arboreal primate whose survival absolutely depends on the forest, the siamang faces population pressure due to habitat loss, poaching, and hunting.
+
+
+=== Habitat loss ===
+
+A major threat to the siamang is habitat fragmentation due to plantations, forest fire, illegal logging, encroachment, and human development. Firstly, palm-oil plantations have removed large areas of the siamang's habitat in recent decades. Since 2002, 107,000 km2 of oil palm have been planted, which has replaced much rainforest in Indonesia and Malaysia, where the siamang originally lived. Secondly, in the second decade of the 21st century, forests in the Malay peninsula have been destroyed due to illegal logging. Sixteen out of the 37 permanent forest reserves in Kelantan, in the Malay peninsula, where most of the siamangs live, have been encroached upon by illegal loggers. Thirdly, forest encroachments change forest cover into cultivated land; for example, the rising price of coffee in 1998 encouraged people in Sumatra to replace the forest with coffee plantations. Fourthly, development in many areas requires infrastructure, such as roads, which now divide conservation areas and have caused forest fragmentation and edge effects.
+
+
+=== Poaching and hunting ===
+Unlike other parts of Asia, primates are not hunted for their meat in Indonesia. They are hunted for the illegal pet trade, with hunters preferring infant siamangs. Poachers often kill the mothers first, since siamang females are highly protective of their infants, and removing the infant without first killing the mother requires more effort. Most siamangs on the market are infants, which often die during transportation.
+

+=== Conservation ===

+The African buffalo (Syncerus caffer) is a large sub-Saharan African bovine. Syncerus caffer caffer, the Cape buffalo, is the typical subspecies, and the largest one, found in Southern and East Africa. S. c. nanus (the forest buffalo) is the smallest subspecies, common in forest areas of Central and West Africa, while  S. c. brachyceros is in West Africa and S. c. aequinoctialis is in the savannas of East Africa. The adult African buffalo's horns are its characteristic feature: they have fused bases, forming a continuous bone shield across the top of the head referred to as a "boss".  It is widely regarded as one of the most dangerous animals on the African continent, and according to some estimates it gores, tramples, and kills over 200 people every year.
+The African buffalo is not an ancestor of domestic cattle and is only distantly related to other larger bovines. Its unpredictable temperament may have been part of the reason that the African buffalo has never been domesticated, unlike its Asian counterpart, the water buffalo. Natural predators of adult African buffaloes include lions, hyenas, and crocodiles. As a member of the big five game, the Cape buffalo is a sought-after trophy in hunting.
+
+
+== Description ==
+
+The African buffalo is a very robust species. Its shoulder height can range from 1.0 to 1.7 m (3.3 to 5.6 ft) and its head-and-body length can range from 1.7 to 3.4 m (5.6 to 11.2 ft). The tail can range from 70 to 110 cm (28 to 43 in) long. Compared with other large bovids, it has a long but stocky body (the body length can exceed the wild water buffalo, which is heavier and taller) and short but thickset legs, resulting in a relatively short standing height. Cape buffaloes weigh 425 to 870 kg (937 to 1,918 lb) (males weigh about 100 kg (220 lb) more than females). In comparison, African forest buffaloes, at 250 to 450 kg (600 to 1,000 lb), are only half that size. Its head is carried low; its top is located below the backline. The front hooves of the buffalo are wider than the rear, which is associated with the need to support the weight of the front part of the body, which is heavier and more powerful than the back.
+Savannah-type buffaloes have black or dark brown coats with age. Old bulls often have whitish circles around their eyes and on their face. Females tend to have more-reddish coats. Forest-type buffaloes are 30-40% smaller, reddish brown in colour, with much more hair growth around the ears and with horns that curve back and slightly up. Calves of both types have red coats.
+A characteristic feature of the horns of adult male African buffalo (southern and eastern populations) is that the bases come very close together, forming a shield referred to as a "boss".  From the base, the horns diverge downwards, then smoothly curve upwards and outwards and in some cases inwards and or backwards. In large bulls, the distance between the ends of the horns can reach upwards of one metre (the record being 64.5 inches 164 cm). The horns form fully when the animal reaches the age of 5 or 6 years old, but the bosses do not become "hard" until it reaches the age of 8 to 9 years old. In cows, the horns are, on average, 10–20% smaller, and they do not have a boss. Forest-type buffalo horns are smaller than those of the savanna-type buffaloes from Southern and East Africa, usually measuring less than 40 centimetres (16 in), and are almost never fused.
+
+
+== Subspecies ==
+
+
+== Ecology ==
+The African buffalo is one of the most successful grazers in Africa. It lives in savannas, swamps and floodplains, as well as mopane grasslands, and the forests of the major mountains of Africa. This buffalo prefers a habitat with dense cover, such as reeds and thickets, but can also be found in open woodland. While not particularly demanding in regard to habitat, they require water daily, and so they depend on perennial sources of water. Like the plains zebra, the buffalo can live on tall, coarse grasses. Herds of buffalo mow down grasses and make way for more selective grazers. When feeding, the buffalo makes use of its tongue and wide incisor row to eat grass more quickly than most other African herbivores. Buffaloes do not stay on trampled or depleted areas for long.
+Other than humans, African buffaloes have few predators and are capable of defending themselves against (and killing) lions. Lions do kill and eat buffaloes regularly, and in some regions, the buffaloes are the lions' primary prey. It often takes several lions to bring down a single adult buffalo, and the entire pride may join in the hunt. However, several incidents have been reported in which lone adult male lions have successfully brought down adult buffaloes. The average-sized Nile crocodile typically attacks only old solitary animals and young calves, though they can kill healthy adults. Exceptionally large, old male crocodiles may become semi-habitual predators of buffaloes.  The cheetah, leopard, African wild dog and spotted hyena are normally a threat only to newborn calves, though larger clans of hyenas have been recorded killing cows (mainly pregnant ones) and, on rare occasions, full-grown bulls. Large packs of wild dogs have been observed to hunt calves and sick adults.
+
+
+=== Diseases ===
+The African buffalo is susceptible to many diseases, including those shared with domestic cattle, such as bovine tuberculosis, corridor disease, and foot and mouth disease. As with many diseases, these problems remain dormant within a population as long as the health of the animals is good. These diseases do, however, restrict the legal movements of the animals and fencing infected areas from unaffected areas is enforced. Some wardens and game managers have managed to protect and breed "disease-free" herds which become very valuable because they can be transported. Most well-known are Lindsay Hunt's efforts to source uninfected animals from the Kruger National Park in South Africa. Some disease-free buffaloes in South Africa have been sold to breeders for close to US$130,000.

+
+== Social behavior ==
+
+Herd size is highly variable. The core of the herds is made up of related females, and their offspring, in an almost linear dominance hierarchy.  The basic herds are surrounded by subherds of subordinate males, high-ranking males and females, and old or invalid animals. 
+African buffaloes engage in several types of group behavior. Females appear to exhibit a sort of "voting behavior". During resting time, the females stand up, shuffle around, and sit back down again. They sit in the direction they think they should move. After an hour of more shuffling, the females travel in the direction they decide. This decision is communal and not based on hierarchy or dominance.When chased by predators, a herd sticks close together and makes it hard for the predators to pick off one member. Calves are gathered in the middle. A buffalo herd responds to the distress call of a threatened member and tries to rescue it. A calf's distress call gets the attention of not only the mother, but also the herd. Buffaloes engage in mobbing behavior when fighting off predators.  They have been recorded killing lions and chasing lions up trees and keeping them there for two hours, after the lions have killed a member of their group. Lion cubs can get trampled and killed. In one videotaped instance, known as the Battle at Kruger, a calf survived an attack by both lions and a crocodile after intervention of the herd.
+Males have a linear dominance hierarchy based on age and size. Since a buffalo is safer when a herd is larger, dominant bulls may rely on subordinate bulls and sometimes tolerate their copulation. The young males keep their distance from the dominant bull, which is recognizable by the thickness of his horns.
+
+Adult bulls spar in play, dominance interactions, or actual fights. A bull approaches another, lowing, with his horns down, and waits for the other bull to do the same thing. When sparring, the bulls twist their horns from side to side. If the sparring is for play, the bull may rub his opponent's face and body during the sparring session. Actual fights are violent but rare and brief. Calves may also spar in play, but adult females rarely spar at all.
+During the dry season, males split from the herd and form bachelor groups. Two types of bachelor herds occur: ones made of males aged four to seven years and those of males 12 years or older. During the wet season, the younger bulls rejoin a herd to mate with the females. They stay with them throughout the season to protect the calves. Some older bulls cease to rejoin the herd, as they can no longer compete with the younger, more aggressive males. The old bachelors are called dagga boys ("mud covered"), and are considered the most dangerous to humans.
+
+
+=== Vocalizations ===
+African buffaloes make various vocalizations. Many calls are lower-pitched versions of those emitted by domestic cattle. They emit low-pitched, two- to four-second calls intermittently at three- to six-second intervals to signal the herd to move. To signal to the herd to change direction, leaders  emit "gritty", "creaking gate" sounds. When moving to drinking places, some individuals make long "maaa" calls up to 20 times a minute. When being aggressive, they make explosive grunts that may last long or turn into a rumbling growl. Cows produce croaking calls when looking for their calves. Calves make a similar call of a higher pitch when in distress. When threatened by predators, they make drawn-out "waaaa" calls. Dominant individuals make calls to announce their presence and location. A version of the same call, but more intense, is emitted as a warning to an encroaching inferior. When grazing, they make various sounds, such as brief bellows, grunts, honks, and croaks.
+
+
+=== Reproduction ===
+African buffaloes mate and give birth only during the rainy seasons. Birth peak takes place early in the season, while mating peaks later. A bull closely guards a cow that comes into heat, while keeping other bulls at bay. This is difficult, as cows are quite evasive and attract many males to the scene. By the time a cow is in full estrus, only the most dominant bull in the herd/subherd is there.
+Cows first calve at five years of age, after a gestation period of 11.5 months. Newborn calves remain hidden in vegetation for the first few weeks while being nursed occasionally by the mother before joining the main herd. Older calves are held in the centre of the herd for safety. The maternal bond between mother and calf lasts longer than in most bovids. That bonding ends when a new calf is born, and the mother then keeps her previous offspring at bay with horn jabs. Nevertheless, the yearling follows its mother for another year or so. Males leave their mothers when they are two years old and join the bachelor groups. Young calves, unusually for bovids, suckle from behind their mothers, pushing their heads between the mothers' legs.

+== Relationship with humans ==
+
+
+=== Status ===
+The current status of the African buffalo is dependent on the animal's value to both trophy hunters and tourists, paving the way for conservation efforts through anti-poaching patrols, village crop damage payouts, and CAMPFIRE payback programs to local areas.
+The African buffalo is listed as Near threatened by the IUCN, with a decreasing population of 400,000 individuals. While some populations (subspecies) are decreasing, others will remain unchanged in the long term if large, healthy populations continue to persist in a substantial number of national parks, equivalent reserves and hunting zones in southern and eastern Africa."In the most recent and available census data at continental scale, the total estimated numbers of the three savanna-type African buffalo subspecies (S. c. caffer, S. c. brachyceros and S. c. aequinoctialis) are at 513,000 individuals.In the past, numbers of African buffaloes suffered their most severe collapse during the great rinderpest epidemic of the 1890s, which, coupled with pleuro-pneumonia, caused mortalities as high as 95% among livestock and wild ungulates.Being a member of the big five game group, a term originally used to describe the five most dangerous animals to hunt, the Cape buffalo is a sought-after trophy, with some hunters paying over $10,000 for the opportunity to hunt one. The larger bulls are targeted for their trophy value, although in some areas, buffaloes are still hunted for meat.
+
+
+=== Attacks ===
+One of the "big five" African game, it is known as "the Black Death" or "the widowmaker", and is widely regarded as a very dangerous animal. According to some estimates, it gores and kills over 200 people every year. African buffaloes are sometimes reported to kill more
+people in Africa than any other animal, although the same claim is also made of hippopotamuses and crocodiles. These numbers may be somewhat overestimated; for example, in the country of Mozambique, attacks, especially fatal ones, were much less frequent on humans than those by hippos and, especially, Nile crocodiles. In Uganda, on the other hand, large herbivores were found to attack more people on average than lions or leopards and have a higher rate of inflicting fatalities during attacks than the predators (the African buffalo, in particular, killing humans in 49.5% of attacks on them), but hippos and even elephants may still kill more people per annum here than buffaloes.  African buffaloes are notorious among big-game hunters as very dangerous animals, with wounded animals reported to ambush and attack pursuers.

+The African buffalo (Syncerus caffer) is a large sub-Saharan African bovine. Syncerus caffer caffer, the Cape buffalo, is the typical subspecies, and the largest one, found in Southern and East Africa. S. c. nanus (the forest buffalo) is the smallest subspecies, common in forest areas of Central and West Africa, while  S. c. brachyceros is in West Africa and S. c. aequinoctialis is in the savannas of East Africa. The adult African buffalo's horns are its characteristic feature: they have fused bases, forming a continuous bone shield across the top of the head referred to as a "boss".  It is widely regarded as one of the most dangerous animals on the African continent, and according to some estimates it gores, tramples, and kills over 200 people every year.
+The African buffalo is not an ancestor of domestic cattle and is only distantly related to other larger bovines. Its unpredictable temperament may have been part of the reason that the African buffalo has never been domesticated, unlike its Asian counterpart, the water buffalo. Natural predators of adult African buffaloes include lions, hyenas, and crocodiles. As a member of the big five game, the Cape buffalo is a sought-after trophy in hunting.
+
+
+== Description ==
+
+The African buffalo is a very robust species. Its shoulder height can range from 1.0 to 1.7 m (3.3 to 5.6 ft) and its head-and-body length can range from 1.7 to 3.4 m (5.6 to 11.2 ft). The tail can range from 70 to 110 cm (28 to 43 in) long. Compared with other large bovids, it has a long but stocky body (the body length can exceed the wild water buffalo, which is heavier and taller) and short but thickset legs, resulting in a relatively short standing height. Cape buffaloes weigh 425 to 870 kg (937 to 1,918 lb) (males weigh about 100 kg (220 lb) more than females). In comparison, African forest buffaloes, at 250 to 450 kg (600 to 1,000 lb), are only half that size. Its head is carried low; its top is located below the backline. The front hooves of the buffalo are wider than the rear, which is associated with the need to support the weight of the front part of the body, which is heavier and more powerful than the back.
+Savannah-type buffaloes have black or dark brown coats with age. Old bulls often have whitish circles around their eyes and on their face. Females tend to have more-reddish coats. Forest-type buffaloes are 30-40% smaller, reddish brown in colour, with much more hair growth around the ears and with horns that curve back and slightly up. Calves of both types have red coats.
+A characteristic feature of the horns of adult male African buffalo (southern and eastern populations) is that the bases come very close together, forming a shield referred to as a "boss".  From the base, the horns diverge downwards, then smoothly curve upwards and outwards and in some cases inwards and or backwards. In large bulls, the distance between the ends of the horns can reach upwards of one metre (the record being 64.5 inches 164 cm). The horns form fully when the animal reaches the age of 5 or 6 years old, but the bosses do not become "hard" until it reaches the age of 8 to 9 years old. In cows, the horns are, on average, 10–20% smaller, and they do not have a boss. Forest-type buffalo horns are smaller than those of the savanna-type buffaloes from Southern and East Africa, usually measuring less than 40 centimetres (16 in), and are almost never fused.
+
+
+== Subspecies ==
+
+
+== Ecology ==
+The African buffalo is one of the most successful grazers in Africa. It lives in savannas, swamps and floodplains, as well as mopane grasslands, and the forests of the major mountains of Africa. This buffalo prefers a habitat with dense cover, such as reeds and thickets, but can also be found in open woodland. While not particularly demanding in regard to habitat, they require water daily, and so they depend on perennial sources of water. Like the plains zebra, the buffalo can live on tall, coarse grasses. Herds of buffalo mow down grasses and make way for more selective grazers. When feeding, the buffalo makes use of its tongue and wide incisor row to eat grass more quickly than most other African herbivores. Buffaloes do not stay on trampled or depleted areas for long.
+Other than humans, African buffaloes have few predators and are capable of defending themselves against (and killing) lions. Lions do kill and eat buffaloes regularly, and in some regions, the buffaloes are the lions' primary prey. It often takes several lions to bring down a single adult buffalo, and the entire pride may join in the hunt. However, several incidents have been reported in which lone adult male lions have successfully brought down adult buffaloes. The average-sized Nile crocodile typically attacks only old solitary animals and young calves, though they can kill healthy adults. Exceptionally large, old male crocodiles may become semi-habitual predators of buffaloes.  The cheetah, leopard, African wild dog and spotted hyena are normally a threat only to newborn calves, though larger clans of hyenas have been recorded killing cows (mainly pregnant ones) and, on rare occasions, full-grown bulls. Large packs of wild dogs have been observed to hunt calves and sick adults.
+
+
+=== Diseases ===
+The African buffalo is susceptible to many diseases, including those shared with domestic cattle, such as bovine tuberculosis, corridor disease, and foot and mouth disease. As with many diseases, these problems remain dormant within a population as long as the health of the animals is good. These diseases do, however, restrict the legal movements of the animals and fencing infected areas from unaffected areas is enforced.

+Reeves's pheasant (Syrmaticus reevesii) is a large pheasant within the genus Syrmaticus. It is endemic to China. It is named after the British naturalist John Reeves, who first introduced live specimens to Europe in 1831.
+
+
+== Description ==
+
+Males measure 210 cm (83 in) long and weigh 1,529 g (3.371 lb). The male is brightly plumaged with a scaled golden white and red body plumage, grey legs, brown iris and bare red skin around the eye. The head is white with a black narrow band across its eyes. The male has an extremely long silvery white tail barred with chestnut brown. This pheasant is mentioned in the 2008 edition of Guinness World Records for having the longest natural tail feather of any bird species; a record formerly held by the crested argus pheasant. The tail can measure up to 2.4 m (7.9 ft) long.Females measure 75 cm (30 in) long and weigh 949 g (2.092 lb). They are brown with a blackish crown, a buff face and greyish brown barred tail feathers. The females are about the same size as a male common pheasant.
+There are no known subspecies, but there is some variation in plumage.
+
+
+== Distribution and habitat ==
+
+The Reeves's pheasant is endemic to the temperate evergreen and deciduous forests of central and eastern China. Where introduced, they also inhabit farmland close to woodlands. The tail of the male bird grows approximately 30 cm (12 in) every year.
+They have been introduced for sport and ornamental purposes to the United States, Czech Republic, France and the United Kingdom. In the latter three countries, they have built up small breeding populations, and are still released on a small scale for shooting, often alongside common pheasants.
+
+
+== Behaviour ==
+
+The Reeves's pheasant is a hardy bird and is able to tolerate both hot and cold weather. They prefer higher ground for nesting. The female lays a clutch of 7–14 eggs in April or May; the incubation period is 24–25 days. Reeves's pheasants are often aggressive towards humans, animals, and other pheasants, particularly during the breeding season.Their call is unlike other game birds in that it is a musical warble, sounding more passerine than a galliform bird. Their diet is vegetable matter, including seeds and cereals. They are fairly common in aviculture.
+
+
+== Conservation ==
+Due to ongoing habitat loss, and overhunting for food and its tail plumes, the Reeves's pheasant is evaluated as Vulnerable on the IUCN Red List of Threatened Species. There are thought to be only around 2000 birds remaining in the wild.
+The species is included in Appendix II of the Convention on International Trade in Endangered Species (CITES) meaning international export/import (including in parts and derivatives such as feathers) requires CITES documentation to be obtained and presented to border authorities.

+The red-crested turaco (Tauraco erythrolophus) is a turaco, a group of African Otidimorphae birds. It is a frugivorous bird endemic to western Angola. Its call sounds somewhat like a jungle monkey.
+
+
+== Description ==
+The red-crested turaco weighs 210-325 g and is 45-50 cm long. It looks similar to the Bannerman's turaco, but differs in crest and face colors. Both sexes are similar.
+
+
+== Behaviour ==
+They are seen in flocks of up to 30 birds, or in pairs. They usually remain in trees, only coming down to eat or drink.
+
+
+=== Voice ===
+A deep barking call. the female's call is slightly higher-pitched than the male's. They are highly vocal, particularly at dawn.
+
+
+=== Reproduction ===
+Red-crested turacos are monogamous. Both mates build a flimsy nest 5 to 20 meters above the ground in dense foliage. After laying eggs, both birds incubate the eggs. The young leave the nest at 4-5 weeks old.
+
+
+== As a national bird ==
+The red-crested turaco is the national bird of Angola. It occurs quite commonly along the length of the Angolan escarpment and adjacent forested habitats.

+The white-cheeked turaco (Menelikornis leucotis) is a species of bird in the family Musophagidae. It is found in Eritrea, Ethiopia, and South Sudan. A mid-sized species, it measures about 43 cm (17 in) in length, including a tail of 19 cm (7.5 in), and weighs about 200–315 g (7.1–11.1 oz).
+This species is the most commonly raised turaco in captive conditions.
+
+
+== Distribution and habitat ==
+The white-cheeked turaco is native to Sudan, South Sudan, Ethiopia and Eritrea, where it is found in Podocarpus and juniper forests in the highland regions.
+
+
+== Subspecies ==
+There are two subspecies, the nominate subspecies M. l. leucotis found in the Podocarpus forests of Eritrea, Ethiopia and southeastern South Sudan and M. l. donaldsoni found in south-central Ethiopia south of the Rift Valley and in the extreme west of Somalia. The latter is quite distinct in plumage colour - the eastern population is separated from the larger population by the escarpment.
+The white-crested turaco has been shown to hybridise with the sympatric Ruspoli's turaco (Menelikornis ruspolii) that contributed more to concerns about Ruspoli's turaco that is considered endangered.
+
+
+== In captivity ==
+In captivity a 'cinnamon' colour sport (a recessive colour mutation) first occurred spontaneously in birds bred by Mr D Jones in Gloucestershire, England and is now present in captive birds in other countries.
+A single white-cheeked turaco has been living wild in east London (Leytonstone and South Woodford). The sighting was recorded and confirmed in October 2009. It has survived the climate and potential predators for at least seven years and appears to be living in harmony with native species. It's believed to be an escaped or released pet. Sightings in gardens have continued to delight Londoners.  In 2014 another bird (or the same one who fancied a change of scenery perhaps?) was sighted in Langton Green, Kent and has caused much interest to the residents, being featured in the village magazine.Sightings in East London have continued into 2017 with the turaco seen in January enjoying scraps under bird feeders in residential gardens near Wanstead Park and in July flying around the treetops in Bushwood.  It was seen again in the trees opposite St Gabriel's Church, Aldersbrook, and photographed on 30 March 2021.  In addition, there have been various sightings of the same (or similar) bird in Wimbledon since April 2016. A turaco was sighted in Havant, Hampshire, in August 2019 and again in May 2020. It has a ring on the left leg. There have been confirmed sightings in Cardiff, Wales from January 2020 and has also been seen in March 2022.

+Livingstone's turaco (Tauraco livingstonii) is a species of bird in the family Musophagidae, which was named for Charles Livingstone, the brother of David Livingstone.
+It is distributed through the subtropical lowlands of southeastern Africa. It has an isolated population in Burundi, and is besides found from southern Tanzania to eastern and southern Malawi, eastern Zimbabwe, widely in Mozambique and along the subtropical coast of South Africa.
+By appearances and behaviour it has much in common with the Knysna turaco of South Africa, and Schalow's turaco which replaces it on the plateau regions to the west of its range.

+The Greek tortoise (Testudo graeca), also known commonly as the spur-thighed tortoise, is a species of tortoise in the family Testudinidae. Testudo graeca is one of five species of Mediterranean tortoises (genera Testudo and Agrionemys). The other four species are Hermann's tortoise (T. hermanni), the Egyptian tortoise (T. kleinmanni), the marginated tortoise (T. marginata), and the Russian tortoise (A. horsfieldii). The Greek tortoise is a very long-lived animal, achieving a lifespan upwards of 125 years, with some unverified reports up to 200 years.
+
+
+== Geographic range ==
+The Greek tortoise's geographic range includes North Africa, Southern Europe, and Southwest Asia. It is prevalent in the Black Sea coast of the Caucasus (from Anapa, Russia, to Sukhumi, Abkhazia, Georgia, to the south), as well as in other regions of Georgia, Armenia, Iran, and Azerbaijan.
+
+
+== Evolution ==
+The oldest known definitive fossil is from the Early Pliocene of Greece, but specimens referred to as Testudo cf. graeca are known from the Late and Middle Miocene in Greece and Turkey.
+
+
+== Characteristics ==
+The Greek tortoise (T. g. ibera) is often confused with Hermann's tortoise (T. hermanni ). However, notable differences enable them to be distinguished.
+
+
+== Subspecies ==
+
+The division of the Greek tortoise into subspecies is difficult and confusing. Given their huge range over three continents, the various terrains, climates, and biotopes have produced a huge number of varieties, with new subspecies constantly being discovered. Currently, at least 20 subspecies are published:
+
+T. g. graeca (North Africa and South Spain)
+T. g. soussensis (South Morocco)
+T. g. marokkensis (North Morocco)
+T. g. nabeulensis - Tunisian tortoise (Tunisia)
+T. g. cyrenaica (Libya)
+T. g. ibera (Turkey)
+T. g. armeniaca - Armenian tortoise (Armenia)
+T. g. buxtoni (Caspian Sea)
+T. g. terrestris (Israel/Lebanon)
+T. g. zarudnyi (Iran/Azerbaijan)
+T. g. whitei (Algeria)
+T. g. floweri (Jordan)This incomplete listing shows the problems in the division of the species into subspecies. The differences in form are primarily in size and weight, as well as coloration, which ranges from dark brown to bright yellow, and the types of flecks, ranging from solid colors to many spots. Also, the bending-up of the edges of their carapaces ranges from minimal to pronounced. So as not to become lost in the number of subspecies, recently, a few tortoises previously classified as T. graeca have been assigned to different species, or even different genera.
+The genetic richness of T. graeca is also shown in its crossbreeding. Tortoises of different form groups often mate, producing offspring with widely differing shapes and color. Perhaps the best means of identification for the future is simply the place of origin.
+The smallest, and perhaps the prettiest, of the subspecies, is the Tunisian tortoise. It has a particularly bright and striking coloration. However, these are also the most sensitive tortoises of the species, so they cannot be kept outdoors in temperate climates, as cold and rainy summers quickly cause the animals to become ill. They are also incapable of long hibernation.
+At the other extreme, animals from northeastern Turkey are very robust, such as Hermann's tortoise. The largest specimens come from Bulgaria. Specimens of 7 kg (15 lb) have been reported. In comparison, the Tunisian tortoise has a maximum weight of 0.7 kg (1.5 lb). T. graeca is also closely related to the marginated tortoise (T. marginata). The two species can interbreed, producing offspring capable of reproduction.
+
+
+== Sexing ==
+Males of T. graeca differ from females in six main points. Firstly, they are generally smaller. Their tails are longer than females and taper to a point evenly, and the cloacal opening is farther from the base of the tail. The underside is somewhat curved, while females have a flat shell on the underside. The rear portion of a male's carapace is wider than it is long. Finally, the posterior plates of the carapace often flange outward.
+
+
+== Mating and reproduction ==
+
+In T. graeca, immediately after waking from hibernation, the mating instinct starts up. The males follow the females with great interest, encircling them, biting them in the limbs, ramming them, and trying to mount them. During copulation, the male opens his mouth, showing his red tongue and making squeaking sounds.
+During mating, the female stands still, bracing herself with her front legs, moving the front part of her body to the left and right in the same rhythm as the male's cries. One successful mating will allow the female to lay eggs multiple times. When breeding in captivity, the pairs of females and males must be kept separate. If multiple males are in a pen, one takes on a dominant role and will try to mate with the other males in the pen. If more males than females are in a pen, the males might kill each other to mate with the females.
+One or two weeks before egg laying, the animals become notably agitated, moving around to smell and dig in the soil, even tasting it, before choosing the ideal spot to lay the eggs. One or two days before egg laying, the female takes on an aggressive, dominant behavior, mounting another animal as for copulation and making the same squeaking sound the male produces during copulation. The purpose of this behavior is to produce respect in the tortoise community so that the female will not be disturbed by the others during egg laying. Further details of egg-laying behavior are the same as those detailed for the marginated tortoise.
+
+
+== Trade ==
+The Greek tortoise is commonly traded as a pet in source countries such as Morocco and Spain, despite the illegality of this trade. This can lead to an unsustainable removal of wild individuals for the local pet trade and for export. Also, welfare concerns exist with this trade, as the animals are not properly housed when being sold, causing a high rate of mortality in captivity.
+
+
+== Food ==
+In captivity, the Greek tortoise loves dandelion leaves and other leafy plants. However, although they also enjoy eating lettuce, it is not recommended to them due to having a lack of nutrients that the tortoises need to survive.

+The Russian tortoise (Testudo horsfieldii), also commonly known as the Afghan tortoise, the Central Asian tortoise, Horsfield's tortoise, four-clawed tortoise, and the (Russian) steppe tortoise, is a threatened species of tortoise in the family Testudinidae. The species is endemic to Central Asia. Human activities in its native habitat contribute to its threatened status.
+
+
+== Etymology ==
+Both the specific name, horsfieldii, and the common name "Horsfield's tortoise" are in honor of the American naturalist Thomas Horsfield.
+
+
+== Systematics ==
+This species is traditionally placed in Testudo. Due to distinctly different morphological characteristics, the monotypic genus Agrionemys was proposed for it in 1966, and was accepted for several decades, although not unanimously. DNA sequence analysis generally concurred, but not too robustly so. However, in 2021, it was again reclassified in Testudo by the Turtle Taxonomy Working Group and the Reptile Database, with Agrionemys being relegated to a distinct subgenus that T. horsfieldii belonged to. The Turtle Taxonomy Working Group lists five separate subspecies of Russian tortoise, but they are not widely accepted by taxonomists:
+T. h. bogdanovi Chkhikvadze, 2008 – southern Krygystan, Tajikistan, Uzbekistan, Turkmenistan
+T. h. horsfieldii (Gray, 1844) – Afghanistan/Pakistan and southern Central Asia
+T. h. kazachstanica Chkhikvadze, 1988 – Kazakhstan/Karakalpakhstan
+T. h. kuznetzovi Chkhikvadze, Ataev, Shammakov & Zatoka, 2009 – northern Turkmenistan, southern Uzbekistan
+T. h. rustamovi Chkhikvadze, Amiranschwili & Atajew, 1990 – southwestern Turkmenistan
+
+
+== Description ==
+The Russian tortoise is a small tortoise species, with a size range of 13–25 cm (5–10 in). Females grow slightly larger (15–25 cm [6–10 in]) to accommodate more eggs. Males average 13–20 cm (5–8 in).
+Russian tortoises are sexually dimorphic. Males tend to have longer tails generally tucked to the side, and longer claws; females have a short, fat tail, with shorter claws than the males. The male has a slit-shaped vent (cloaca) near the tip of its tail; the female has an asterisk-shaped vent (cloaca).
+Russian tortoises have four toes. Coloration varies, but the shell is usually a ruddy brown or black, fading to yellow between the scutes, and the body is straw-yellow and brown depending on the subspecies.
+The male Russian tortoise courts a female through head bobbing, circling, and biting her forelegs. When she submits, he mounts her from behind, making high-pitched squeaking noises during mating.The species can spend as much as 9 months of the year in dormancy. 
+
+
+== Captivity ==
+Russian tortoises are popular pets. They can be kept indoors or outdoors, but outdoor tortoise enclosures generally require less equipment and upkeep, and are preferable if the keeper lives in an appropriate climate. Indoor enclosures should measure 8’L x 4’W x 2.5’H, or otherwise offer 32 square feet of floor space. Indoors, specialized equipment is required to maintain moderate temperatures and moderate humidity, with UVB light available in an appropriate strength.
+In captivity, Russian tortoises’ diet typically consists of lamb's lettuce, plantains and various other dark leafy greens. The diet should be as varied as possible to reduce the risk of imbalanced nutrition. Water is important for all species; the tortoise, being an arid species, will typically get water from their food, but they still need a constant supply. Young Russian tortoises should be soaked 1-2x/weekly in lukewarm water no deeper than their elbows to keep hydrated. Tortoises typically empty their bowels in water to hide their scent; this is an instinct, and it also helps keep their enclosure cleaner.Russian tortoises can live up to 50 years, and require annual hibernation.
+Russian tortoises do not require a CITES Article X certificate.
+
+
+== 1968 Moon flight ==
+In September 1968 two Russian tortoises flew to the Moon, circled it, and returned safely to Earth on the Soviet Zond 5 mission. Accompanied by mealworms, plants, and other lifeforms, they were the first Earth creatures to travel to the Moon.

+The marginated tortoise (Testudo marginata) is a species of tortoise in the family Testudinidae. The species is endemic to Greece, Italy, and the Balkans in Southern Europe. It is the largest European tortoise. The marginated tortoise is herbivorous, and brumates for the winter. 
+
+
+== Taxonomy ==
+
+The marginated tortoise was formally described by German naturalist Johann David Schoepff in 1789; its specific epithet marginata is a straightforward derivation from the Latin term for 'marginated'.
+The nominate subspecies is the Greek marginated tortoise, Testudo marginata marginata. Three additional subspecies of marginated tortoises have been named:
+The Sardinian marginated tortoise (T. m. sarda) is the name usually used to separate the population on the island of Sardinia. These tortoises have less strongly bent tiles in the posterior of their carapaces, and the posterior of the carapace is almost smooth compared with the saw-like T. m. marginata. Clearly distinct according to morphology and entirely allopatric, it cannot be distinguished by mtDNA cytochrome b and nDNA ISSR sequence analysis. Lineage sorting has not occurred to a considerable degree; consequently, the more geographically isolated Sardinian population is presumably of quite recent origin.
+Indeed, it appears to derive from a deliberate introduction by humans. Though it is not clear whether this occurred in prehistoric times or more recently, this might be resolved by dating subfossil remains. Sequence evolution at least in mtDNA is known to proceed much more slowly in some turtles and tortoises than in others; the rate of the mitochondrial 12S rRNA gene in Testudo is probably a rather low 1.0–1.6% per million years (as this fits best the paleobiogeographical situation), limiting the resolution provided by molecular systematics.An extinct subspecies described as T. m. cretensis persisted on Crete before the end of the last ice age, presumably larger than mainland tortoises. However, numerous additional fossils have since refuted the validity of this subspecies.A population of small and light-colored marginated tortoises exists on the southwestern coast of the Peloponnesus, between Kalamata and south of Stoupa. The so-called "dwarf marginated tortoise" was described as a new species Testudo weissingeri, but it is not recognizably distinct phylogenetically. Unlike the Sardinian population, it occupies an extremely restricted range with very arid habitat, and its apomorphies seem related to this. Considering ice age-associated climate and sea level changes, this population is probably not older than a few thousand years; as it is not geographically isolated, it should be considered a local form, and not even a subspecies T. m. weissingeri. Notably, a similar situation is found in Hermann's tortoises living in the same region.Testudo marginata is also closely related to the Greek or common tortoise (Testudo graeca). Both have very similar bodily characteristics—oblong carapaces, large scales on the front legs, large coverings for the head and cone-like scales on the upper thighs, undivided tail coverings, moveable stomach plates, and lack of tail spikes. Presumably, Testudo marginata diverged from ancestral Testudo graeca as a population more suited for life in the mountainous regions. Evidence in favor of this is the wide geographical region and the extremely large number of subspecies of Testudo graeca, including a subspecies in Turkey with strongly bent carapace tiles, like the marginated tortoise. Testudo marginata on the other hand, despite the two subspecies, presents a much more unified appearance, which points toward an earlier appearance in evolutionary history. In captivity, the two species often cross-breed, but this should be avoided.
+According to the 2005 DNA sequence data, these species do not seem to hybridize to a notable extent in the wild, though they are obviously very close relatives, and as evidenced by morphology, some allele flow still occurs, but slowly. The Egyptian tortoise appears to represent a lineage that diverged from the same ancestral stock southwards into northeastern Africa around the same time as the marginated tortoise's ancestors diverged in Greece. These two are actually more similar to each other than to T. graeca regarding DNA sequence data, but considering biogeography, this is either due to (rather unlikely) dispersal across the Mediterranean, or the supposed "clade" is invalid and the similarity due to convergent evolution.
+
+
+== Description ==
+The marginated tortoise is the largest European tortoise, reaching a weight of up to 5 kg (11 lb) and a length of 35 cm (14 in). Its shell is oblong and has a notable thickness around the middle of the body. The posterior end of the shell has a saw-like formation, flanged outward like a bell. The carapace of an adult specimen is almost completely black, with yellow highlights.  The ventral shell is lighter-coloured and has pairs of triangular markings with the points facing the rear of the animal. The front sides of the limbs are covered with large scales. In an old female specimen, the rear flaps of the underside of her plastron is somewhat moveable. The tail is notable for a lengthwise marking and for an undivided carapace over the tail. The male has a longer tail, which is thicker at the base than the female's. The underside is more strongly indented. Males are also often larger than the females. The females lay their hard-shelled spherical eggs in the soil in May and June.
+
+
+== Distribution and habitat ==
+
+The natural range of the marginated tortoise is southern Greece, from the Peloponnesus to Mount Olympus. They are also found in isolated zones of the Balkans and Italy, and northeastern Sardinia.
+The marginated tortoise lives in more mountainous regions than Hermann's tortoise. It can be found in elevations as high as 1,600 m (5,200 ft). The black color of the carapace is helpful for survival in this environment, as it allows the tortoise to absorb a great deal of heat in a short time, helping it maintain its body temperature. Early in the morning, marginated tortoises bask in the sun to raise their body temperature, and then search for food. After feeding, the tortoises return to their shelters in the hot midday hours, leaving them again in the late afternoon.
+
+
+== Behaviour ==
+Marginated tortoises are fairly calm and relaxed, although they can be somewhat territorial in the wild. They have a controlled temper and are generally slow to anger. If they are not given the proper diet in captivity, however, they will become rather aggressive and might mistakenly attack if they feel threatened.
+
+
+=== Diet ===
+Marginated tortoises are herbivorous, their diets consisting primarily of plants from their native Mediterranean region. 
+
+
+=== Reproduction ===
+Immediately after waking from brumation, the mating instinct starts up. The males follow the females with great interest, encircling them, biting them on the limbs, ramming them, and trying to mount them. During copulation, the male opens his mouth, showing his red tongue and making loud cries. The tone of the copulation cry is almost sobbing with long, deep tones, in contrast to T. hermanni, which uses a much higher-toned, peeping noise.
+During mating, the female stands still and holds her head to the side, looking up to see the opened mouth of the male. The red tongue apparently serves a signalling function. The female moves her head from left to right in the same rhythm as the male's cries.
+Afterwards, the female seeks out an adequate location to lay her eggs. Once such a place is found, the female stands still, propping both front legs firmly against the ground. Then she digs out a hole with her hind legs, alternating between left and right, beginning with simply scratching the ground but eventually moving large quantities of soil which are piled up beside the hole. The depth of the hole is determined by the length of her hind legs. If the ground is too hard to dig, the female releases water from her anal gland to soften it.
+Once the hole is dug, egg-laying begins. Each egg is gently rolled back into the hole. After the last egg, the female immediately begins refilling the hole, again using her hind legs. Finally, she stamps the opening closed with her feet so that the ground regains its natural hardness. Larger animals may lay eggs as many as three times per summer, with about 15 eggs per clutch.
+
+The incubation period averages about 100 days under natural conditions, which is relatively short among tortoises. Many tropical tortoises have incubation periods of up to 200 days. The relatively short time is an adaptation to the subtropical Mediterranean climate, where the summers are not as long. In an incubator, this time is notably shorter: with an incubation temperature of 31.5 °C (88.7 °F) the eggs will begin hatching after 60 days.
+Unlike bird eggs, the yolk and albumen of reptile eggs are not separated by a membrane. After a few days, the heavy yolk components sink to the bottom of the egg. On top of this floats the embryonal disk, surrounded by albumen, so the tortoise eggs cannot be turned after the yolk settles without damaging or killing the embryo.
+It is possible to see with the naked eye if the eggs are developing healthily. Freshly laid eggs have a gray-white color. Shortly thereafter, a bright white spot forms on the uppermost point of the egg. This spot gradually grows until the entire egg is bright white.
+After the embryo has developed fully in the egg, the young animal breaks the shell with its egg tooth from inside, creates a small opening, and for the first time fills its lungs with air. Afterwards, it pulls back into the egg and works on the shell with its beak until it opens completely. In nature, the animal remains below ground for the first two weeks, where it is safe from predators, yet is still able to grow, as it is nourished by the yolk sac. The young animals lead cautious and secretive lives, normally remaining in the shade. They avoid full sunlight because of the great danger of overheating.
+Marginated tortoises grow very rapidly. In an ideal biotope, or with good handling, they gain 100–500 g (3.5–17.6 oz) yearly. This quick rate of growth lasts throughout their youth. After the 20th year of life, further growth is minimal. They may live between 100 and 140 years, according to the best estimates of scientists.

+The marginated tortoise (Testudo marginata) is a species of tortoise in the family Testudinidae. The species is endemic to Greece, Italy, and the Balkans in Southern Europe. It is the largest European tortoise. The marginated tortoise is herbivorous, and brumates for the winter. 
+
+
+== Taxonomy ==
+
+The marginated tortoise was formally described by German naturalist Johann David Schoepff in 1789; its specific epithet marginata is a straightforward derivation from the Latin term for 'marginated'.
+The nominate subspecies is the Greek marginated tortoise, Testudo marginata marginata. Three additional subspecies of marginated tortoises have been named:
+The Sardinian marginated tortoise (T. m. sarda) is the name usually used to separate the population on the island of Sardinia. These tortoises have less strongly bent tiles in the posterior of their carapaces, and the posterior of the carapace is almost smooth compared with the saw-like T. m. marginata. Clearly distinct according to morphology and entirely allopatric, it cannot be distinguished by mtDNA cytochrome b and nDNA ISSR sequence analysis. Lineage sorting has not occurred to a considerable degree; consequently, the more geographically isolated Sardinian population is presumably of quite recent origin.
+Indeed, it appears to derive from a deliberate introduction by humans. Though it is not clear whether this occurred in prehistoric times or more recently, this might be resolved by dating subfossil remains. Sequence evolution at least in mtDNA is known to proceed much more slowly in some turtles and tortoises than in others; the rate of the mitochondrial 12S rRNA gene in Testudo is probably a rather low 1.0–1.6% per million years (as this fits best the paleobiogeographical situation), limiting the resolution provided by molecular systematics.An extinct subspecies described as T. m. cretensis persisted on Crete before the end of the last ice age, presumably larger than mainland tortoises. However, numerous additional fossils have since refuted the validity of this subspecies.A population of small and light-colored marginated tortoises exists on the southwestern coast of the Peloponnesus, between Kalamata and south of Stoupa. The so-called "dwarf marginated tortoise" was described as a new species Testudo weissingeri, but it is not recognizably distinct phylogenetically. Unlike the Sardinian population, it occupies an extremely restricted range with very arid habitat, and its apomorphies seem related to this. Considering ice age-associated climate and sea level changes, this population is probably not older than a few thousand years; as it is not geographically isolated, it should be considered a local form, and not even a subspecies T. m. weissingeri. Notably, a similar situation is found in Hermann's tortoises living in the same region.Testudo marginata is also closely related to the Greek or common tortoise (Testudo graeca). Both have very similar bodily characteristics—oblong carapaces, large scales on the front legs, large coverings for the head and cone-like scales on the upper thighs, undivided tail coverings, moveable stomach plates, and lack of tail spikes. Presumably, Testudo marginata diverged from ancestral Testudo graeca as a population more suited for life in the mountainous regions. Evidence in favor of this is the wide geographical region and the extremely large number of subspecies of Testudo graeca, including a subspecies in Turkey with strongly bent carapace tiles, like the marginated tortoise. Testudo marginata on the other hand, despite the two subspecies, presents a much more unified appearance, which points toward an earlier appearance in evolutionary history. In captivity, the two species often cross-breed, but this should be avoided.
+According to the 2005 DNA sequence data, these species do not seem to hybridize to a notable extent in the wild, though they are obviously very close relatives, and as evidenced by morphology, some allele flow still occurs, but slowly. The Egyptian tortoise appears to represent a lineage that diverged from the same ancestral stock southwards into northeastern Africa around the same time as the marginated tortoise's ancestors diverged in Greece. These two are actually more similar to each other than to T. graeca regarding DNA sequence data, but considering biogeography, this is either due to (rather unlikely) dispersal across the Mediterranean, or the supposed "clade" is invalid and the similarity due to convergent evolution.
+
+
+== Description ==
+The marginated tortoise is the largest European tortoise, reaching a weight of up to 5 kg (11 lb) and a length of 35 cm (14 in). Its shell is oblong and has a notable thickness around the middle of the body. The posterior end of the shell has a saw-like formation, flanged outward like a bell. The carapace of an adult specimen is almost completely black, with yellow highlights.  The ventral shell is lighter-coloured and has pairs of triangular markings with the points facing the rear of the animal. The front sides of the limbs are covered with large scales. In an old female specimen, the rear flaps of the underside of her plastron is somewhat moveable. The tail is notable for a lengthwise marking and for an undivided carapace over the tail. The male has a longer tail, which is thicker at the base than the female's. The underside is more strongly indented. Males are also often larger than the females. The females lay their hard-shelled spherical eggs in the soil in May and June.
+
+
+== Distribution and habitat ==
+
+The natural range of the marginated tortoise is southern Greece, from the Peloponnesus to Mount Olympus. They are also found in isolated zones of the Balkans and Italy, and northeastern Sardinia.
+The marginated tortoise lives in more mountainous regions than Hermann's tortoise. It can be found in elevations as high as 1,600 m (5,200 ft). The black color of the carapace is helpful for survival in this environment, as it allows the tortoise to absorb a great deal of heat in a short time, helping it maintain its body temperature. Early in the morning, marginated tortoises bask in the sun to raise their body temperature, and then search for food. After feeding, the tortoises return to their shelters in the hot midday hours, leaving them again in the late afternoon.
+
+
+== Behaviour ==
+Marginated tortoises are fairly calm and relaxed, although they can be somewhat territorial in the wild. They have a controlled temper and are generally slow to anger. If they are not given the proper diet in captivity, however, they will become rather aggressive and might mistakenly attack if they feel threatened.

+Tiliqua scincoides (common blue-tongued skink, blue-tongued lizard, common bluetongue) is a species of skink. It is native to Australia as well as to the Tanimbar and Babar Islands in the Maluku Province of Indonesia.
+
+
+== Subspecies ==
+There are three subspecies:
+Tiliqua scincoides scincoides – eastern blue-tongued skink (southern/eastern Australia)
+Tiliqua scincoides intermedia – northern blue-tongued skink (northern Australia)
+Tiliqua scincoides chimaera – Tanimbar blue-tongued skink (Maluku Province, Indonesia)
+
+
+== Description ==
+This is a large terrestrial lizard measuring up to 60 centimetres long and 1 kilogram in mass. It has a stout body and short legs. It is variable in color but generally has a banded pattern. The tongue is blue-violet to cobalt blue in color. Due to its characteristic blue tongue and its curious nature, it is a popular companion animal in Western countries.This lizard is diurnal, active during the day. It is omnivorous, feeding on insects, snails, frogs, other reptiles, small birds, small mammals, carrion, some plant material, fruits, and fungi. It is ovoviviparous, the eggs hatching inside the female's body; she then gives birth to 5 to 25 live young per litter. This species is known to live over 30 years. It is an adaptable animal, often finding habitat in urban and suburban areas, including residential areas of Sydney. The lizard is considered beneficial in these areas, with its appetite for garden pests such as slugs and snails.When threatened it may hiss and reveal its blue tongue, startling potential predators.
+There are three color-morphs of Tiliqua scincoides: albino, wild-type, and melanistic.  In warm environments, the wild-type T. scincoides and melanistic T. scincoides have skin with lower reflectance compared to the albino T. scincoides, therefore these two lizards can warm their bodies at a faster rate.

+The red-eared slider or red-eared terrapin (Trachemys scripta elegans) is a subspecies of the pond slider (Trachemys scripta), a semiaquatic turtle belonging to the family Emydidae. It is the most popular pet turtle in the United States, is also popular as a pet across the rest of the world, and is the most invasive turtle. It is the most commonly traded turtle in the world.The red-eared slider is native from the Midwestern United States to northern Mexico, but has become established in other places because of pet releases, and has become invasive in many areas where it outcompetes native species. The red-eared slider is included in the list of the world's 100 most invasive species.
+
+
+== Etymology ==
+
+The red-eared slider gets its name from the small, red stripe around its ears, or where its ears would be, and from its ability to slide quickly off rocks and logs into the water. This species was previously known as Troost's turtle in honor of an American herpetologist Gerard Troost. Trachemys scripta troostii is now the scientific name for another subspecies, the Cumberland slider.
+
+
+== Taxonomy ==
+The red-eared slider belongs to the order Testudines, which contains about 250 turtle species. It is a subspecies of Trachemys scripta. It was previously classified under the name Chrysemys scripta elegans. Trachemys scripta contains three subspecies: T. s. elegans (red-eared slider), T. s. scripta (yellow-bellied slider), and T. s. troostii (Cumberland slider).
+
+
+== Description ==
+
+The carapace of this species can reach more than 40 cm (16 in) in length, but the typical length ranges from 15 to 20 cm (6 to 8 in). The females of the species are usually larger than the males. They typically live between 20–30 years, although some individuals have lived for more than 40 years. Their life expectancy is shorter when they are kept in captivity. The quality of their living environment has a strong influence on their lifespans and well being.
+These turtles are poikilotherms, meaning they are unable to regulate their body temperatures independently; they are completely dependent on the temperature of their environment. For this reason, they need to sunbathe frequently to warm themselves and maintain their body temperatures.
+The shell is divided into the upper or dorsal carapace, and the lower, ventral carapace or plastron. The upper carapace consists of the vertebral scutes, which form the central, elevated portion; pleural scutes that are located around the vertebral scutes; and then the marginal scutes around the edge of the carapace. The rear marginal scutes are notched. The scutes are bony keratinous elements. The carapace is oval and flattened (especially in the male) and has a weak keel that is more pronounced in the young. The color of the carapace changes depending on the age of the turtle. It usually has a dark green background with light and dark, highly variable markings. In young or recently hatched turtles, it is leaf green and gets slightly darker as a turtle gets older, until it is a very dark green, and then turns a shade between brown and olive green. The plastron is always a light yellow with dark, paired, irregular markings in the centre of most scutes. The plastron is highly variable in pattern. The head, legs, and tail are green with fine, irregular, yellow lines. The whole shell is covered in these stripes and markings that aid in camouflaging an individual.
+
+ 
+These turtles also have a complete skeletal system, with partially webbed feet that help them to swim and that can be withdrawn inside the carapace along with the head and tail. The red stripe on each side of the head distinguishes the red-eared slider from all other North American species and gives this species its name, as the stripe is located behind the eyes, where their (external) ears would be. These stripes may lose their color over time. Some individuals can also have a small mark of the same color on the top of their heads. The red-eared slider does not have a visible outer ear or an external auditory canal; instead, it relies on a middle ear entirely covered by a cartilaginous tympanic disc.
+
+
+=== Sexual dimorphism ===
+
+Some dimorphism exists between males and females.Red-eared slider young look practically identical regardless of their sex, making distinguishing them difficult. One useful method, however, is to inspect the markings under their carapace, which fade as the turtles age. Distinguishing the sex of adults is much easier, as the shells of mature males are smaller than those of females. Male red-eared sliders reach sexual maturity when their carapaces' diameters measure 10 cm (3.9 in) and females reach maturity when their carapaces measure about 15 cm. Both males and females reach sexual maturity at 5–6 years old. Males are normally smaller than females, although this parameter is sometimes difficult to apply, as individuals being compared could be of different ages.
+Males have longer claws on their front feet than the females; this helps them to hold onto a female during mating, and is used during courtship displays. The males' tails are thicker and longer. Typically, the cloacal opening of a female is at or under the rear edge of the carapace, while the male's opening occurs beyond the edge of the carapace. The male's plastron is slightly concave, while that of the female is completely flat. The male's concave plastron also helps to stabilize the male on the female's carapace during mating. Older males can sometimes have a dark greyish-olive green melanistic coloration, with very subdued markings. The red stripe on the sides of the head may be difficult to see or be absent. The female's appearance is substantially the same throughout her life.
+
+
+== Distribution and habitat ==
+The red-eared slider originated from the area around the Mississippi River and the Gulf of Mexico, in warm climates in the Southeastern United States. Their native areas range from the southeast of Colorado to Virginia and Florida. In nature, they inhabit areas with a source of still, warm water, such as ponds, lakes, swamps, creeks, streams, or slow-flowing rivers.
+They live in areas of calm water, where they are able to leave the water easily by climbing onto rocks or tree trunks so they can warm up in the sun. Individuals are often found sunbathing in a group or even on top of each other. They also require abundant aquatic plants, as these are the adults' main food, although they are omnivores. Turtles in the wild always remain close to water unless they are searching for a new habitat or when females leave the water to lay their eggs.
+
+
+=== Invasive species ===
+Invasive red-eared sliders cause negative impacts in the ecosystems they occupy because they have certain advantages over the native populations, such as a lower age at maturity, higher fecundity rates, and larger body size, which gives them a competitive advantage at basking and nesting sites, as well as when exploiting food resources. They also transmit diseases and displace the other turtle species with which they compete for food and breeding space.Owing to their popularity as pets, red-eared sliders have been released or escaped into the wild in many parts of the world. This turtle is considered one of the world's worst invasive species. Feral populations are now found in Bermuda, Canada, Australia, Europe, Great Britain, South Africa, the Caribbean Islands, Israel, Bahrain, the Mariana Islands, Guam, and south- and far-east Asia. Within Great Britain, red-eared sliders have a wide distribution throughout England, Scotland, and Wales.In Australia, it is illegal for members of the public to import, keep, trade, or release red-eared sliders, as they are regarded as an invasive species – see below. Their import has been banned by the European Union as well as specific EU member countries. In 2015, Japan announced it was planning to ban the import of red-eared sliders, but it would probably not take effect until 2020.
+
+
+== Behavior ==
+Red-eared sliders are almost entirely aquatic, but as they are cold-blooded, they leave the water to sunbathe to regulate their temperature.
+
+
+=== Hibernation ===
+Red-eared sliders do not hibernate, but actually brumate; while they become less active, they do occasionally rise to the surface for food or air. Brumation can occur to varying degrees. In the wild, red-eared sliders brumate over the winter at the bottoms of ponds or shallow lakes. They generally become inactive in October, when temperatures fall below 10 °C (50 °F). During this time, the turtles enter a state of sopor, during which they do not eat or defecate, they remain nearly motionless, and the frequency of their breathing falls. Individuals usually brumate under water, but they have also been found under banks and rocks, and in hollow stumps. In warmer winter climates, they can become active and come to the surface for basking. When the temperature begins to drop again, however, they quickly return to a brumation state. Sliders generally come up for food in early March to as late as the end of April.
+
+During brumation, T. s. elegans can survive anaerobically for weeks, producing ATP from glycolysis. The turtle's metabolic rate drops dramatically, with heart rate and cardiac output dropping by 80% to minimize energy requirements.
+The lactic acid produced is buffered by minerals in the shell, preventing acidosis.
+Red-eared sliders kept captive indoors should not brumate.
+
+
+=== Reproduction ===
+
+Courtship and mating activities for red-eared sliders usually occur between March and July, and take place under water. During courtship, the male swims around the female and flutters or vibrates the back side of his long claws on and around her face and head, possibly to direct pheromones towards her. The female swims toward the male, and if she is receptive, sinks to the bottom for mating. If the female is not receptive, she may become aggressive towards the male. Courtship can last 45 minutes, but mating takes only 10 minutes.
+On occasion, a male may appear to be courting another male, and when kept in captivity may also show this behaviour towards other household pets. Between male turtles, it could be a sign of dominance and may preclude a fight. Young turtles may carry out the courtship dance before they reach sexual maturity at 5 years of age, but they are unable to mate.After mating, the female spends extra time basking to keep her eggs warm. She may also have a change of diet, eating only certain foods, or not eating as much as she normally would. A female can lay between two and 30 eggs depending on body size and other factors. One female can lay up to 5 clutches in the same year, and clutches are usually spaced 12–36 days apart. The time between mating and egg-laying can be days or weeks. The actual egg fertilization takes place during the egg-laying. This process also permits the laying of fertile eggs the following season, as the sperm can remain viable and available in the female's body in the absence of mating. During the last weeks of gestation, the female spends less time in the water and smells and scratches at the ground, indicating she is searching for a suitable place to lay her eggs. The female excavates a hole, using her hind legs, and lays her eggs in it.
+Incubation takes 59–112 days. Late-season hatchlings may spend the winter in the nest and emerge when the weather warms in the spring. Just prior to hatching, the egg contains 50% turtle and 50% egg sac. A new hatchling breaks open its egg with its egg tooth, which falls out about an hour after hatching. This egg tooth never grows back. Hatchlings may stay inside their eggshells after hatching for the first day or two. If they are forced to leave the eggshell before they are ready, they will return if possible. When a hatchling decides to leave the shell, it still has a small sac protruding from its plastron. The yolk sac is vital and provides nourishment while visible, and several days later, it will have been absorbed into the turtle's belly. The sac must be absorbed, and does not fall off. The split must heal on its own before the turtle is able to swim. The time between the egg hatching and water entry is 21 days.
+
+Damage to or inordinate motion of the protruding egg yolk – enough to allow air into the turtle's body – results in death. This is the main reason for marking the top of turtle eggs if their relocation is required for any reason. An egg turned upside down will eventually terminate the embryo's growth by the sac smothering the embryo. If it manages to reach term, the turtle will try to flip over with the yolk sac, which would allow air into the body cavity and cause death. The other fatal danger is water getting into the body cavity before the sac is absorbed completely, and while the opening has not completely healed yet.
+The sex of red-eared sliders is determined by the incubation temperature during critical phases of the embryos' development. Only males are produced when eggs are incubated at temperatures of 22–27 °C (72–81 °F), whereas females develop at warmer temperatures. Colder temperatures result in the death of the embryos.
+
+
+== As pets, invasive species, and human infection risk ==
+
+Red-eared slider turtles are the world's most commonly traded reptile, due to their relatively low price, and usually low food price, small size, and easy maintenance. As with other turtles, tortoises, and box turtles, individuals that survive their first year or two can be expected to live generally around 30 years. They present an infection risk; particularly of Salmonella.
+
+
+=== Infection risks and United States federal regulations on commercial distribution ===
+
+Reptiles are asymptomatic (meaning they suffer no adverse side effects) carriers of bacteria of the genus Salmonella. This has given rise to justifiable concerns given the many instances of infection of humans caused by the handling of turtles, which has led to restrictions in the sale of red-eared sliders in the USA. A 1975 U.S. Food and Drug Administration (FDA) regulation bans the sale (for general commercial and public use) of both turtle eggs and turtles with a carapace length less than 4 in (10 cm). This regulation comes under the Public Health Service Act, and is enforced by the FDA in cooperation with state and local health jurisdictions. The ban was enacted because of the public-health impact of turtle-associated salmonellosis. Turtles and turtle eggs found to be offered for sale in violation of this provision are subject to destruction in accordance with FDA procedures. A fine up to $1,001 and / or imprisonment for up to one year is the penalty for those who refuse to comply with a valid final demand for destruction of such turtles or their eggs. Many stores and flea markets still sell small turtles due to an exception in the FDA regulation that allows turtles under 4 in (10 cm) to be sold "for bona fide scientific, educational, or exhibition purposes, other than use as pets." As with many other animals and inanimate objects, the risk of Salmonella exposure can be reduced by following basic rules of cleanliness. Small children must be taught to wash their hands immediately after they finish playing with the turtle, feeding it, or changing its water.
+
+
+=== US state laws ===
+Some states have other laws and regulations regarding possession of red-eared sliders because they can be an invasive species where they are not native and have been introduced through the pet trade. Now, it is illegal in Florida to sell any wild-type red-eared slider, as they interbreed with the local yellow-bellied slider population, T. s. scripta, which is another subspecies of pond sliders, and hybrids typically combine the markings of the two subspecies. However, unusual color varieties such as albino and pastel red-eared sliders, which are derived from captive breeding, are still allowed for sale.
+
+
+=== Invasive status in Australia ===
+In Australia, breeding populations have been found in New South Wales and Queensland, and individual turtles have been found in the wild in Victoria, the Australian Capital Territory, and Western Australia.Red-eared slider turtles are considered a significant threat to native turtle species; they mature more quickly, grow larger, produce more offspring, and are more aggressive. Numerous studies indicate that red-eared slider turtles can out-compete native turtles for food and nesting and basking sites. Unlike the general diet of pet red-eared sliders, wild red-eared sliders are usually omnivorous.  Because red-eared slider turtles eat plants as well as animals, they could also have a negative impact on a range of native aquatic species, including rare frogs. Also, a significant risk exists that red-eared slider turtles can transfer diseases and parasites to native reptile species. A malaria-like parasite was spread to two wild turtle populations in Lane Cove River, Sydney.Social and economic costs are also likely to be substantial. The Queensland government has invested close to AU$1 million in eradication programs to date. The turtle may also cause significant public-health costs due to the impacts of turtle-associated salmonella on human health. Outbreaks in multiple states and fatalities in children, associated with handling salmonella-infected turtles, have been recorded in the USA. Salmonella can also spread to humans when turtles contaminate drinking water.The actions by state governments have varied considerably to date, ranging from ongoing eradication efforts by the Queensland government to very little action by the government of New South Wales. Experts have ranked the species as high priority for management in Australia, and are calling for a national prevention and eradication strategy, including a concerted education and compliance program to stop the illegal trade, possession, and release of slider turtles.
+
+
+=== Invasive status in India ===
+Red-eared slider turtles are threatening to invade the natural water bodies across northeast India, which are home to 21 out of 29 vulnerable native Indian species of freshwater turtle. Between August 2018 and June 2019, a team of herpetologists from the NGO "Help Earth" found red-eared sliders in the Deepor Beel wildlife sanctuary and Ugratara Devalaya temple pond. Further reports have been made from an unnamed stream, feeding into the Tlawng river, on a farm in the Mizoram capital, Aizawl.
+
+
+== In popular culture ==
+Within the second volume of the Tales of the Teenage Mutant Ninja Turtles, the popular comic-book heroes were revealed as specimens of the red-eared slider. The popularity of the Ninja Turtles led to a craze for keeping them as pets in United Kingdom, with subsequent ecological havoc, as turtles were accidentally or deliberately released into the wild.

+The red-eared slider or red-eared terrapin (Trachemys scripta elegans) is a subspecies of the pond slider (Trachemys scripta), a semiaquatic turtle belonging to the family Emydidae. It is the most popular pet turtle in the United States, is also popular as a pet across the rest of the world, and is the most invasive turtle. It is the most commonly traded turtle in the world.The red-eared slider is native from the Midwestern United States to northern Mexico, but has become established in other places because of pet releases, and has become invasive in many areas where it outcompetes native species. The red-eared slider is included in the list of the world's 100 most invasive species.
+
+
+== Etymology ==
+
+The red-eared slider gets its name from the small, red stripe around its ears, or where its ears would be, and from its ability to slide quickly off rocks and logs into the water. This species was previously known as Troost's turtle in honor of an American herpetologist Gerard Troost. Trachemys scripta troostii is now the scientific name for another subspecies, the Cumberland slider.
+
+
+== Taxonomy ==
+The red-eared slider belongs to the order Testudines, which contains about 250 turtle species. It is a subspecies of Trachemys scripta. It was previously classified under the name Chrysemys scripta elegans. Trachemys scripta contains three subspecies: T. s. elegans (red-eared slider), T. s. scripta (yellow-bellied slider), and T. s. troostii (Cumberland slider).
+
+
+== Description ==
+
+The carapace of this species can reach more than 40 cm (16 in) in length, but the typical length ranges from 15 to 20 cm (6 to 8 in). The females of the species are usually larger than the males. They typically live between 20–30 years, although some individuals have lived for more than 40 years. Their life expectancy is shorter when they are kept in captivity. The quality of their living environment has a strong influence on their lifespans and well being.
+These turtles are poikilotherms, meaning they are unable to regulate their body temperatures independently; they are completely dependent on the temperature of their environment. For this reason, they need to sunbathe frequently to warm themselves and maintain their body temperatures.
+The shell is divided into the upper or dorsal carapace, and the lower, ventral carapace or plastron. The upper carapace consists of the vertebral scutes, which form the central, elevated portion; pleural scutes that are located around the vertebral scutes; and then the marginal scutes around the edge of the carapace. The rear marginal scutes are notched. The scutes are bony keratinous elements. The carapace is oval and flattened (especially in the male) and has a weak keel that is more pronounced in the young. The color of the carapace changes depending on the age of the turtle. It usually has a dark green background with light and dark, highly variable markings. In young or recently hatched turtles, it is leaf green and gets slightly darker as a turtle gets older, until it is a very dark green, and then turns a shade between brown and olive green. The plastron is always a light yellow with dark, paired, irregular markings in the centre of most scutes. The plastron is highly variable in pattern. The head, legs, and tail are green with fine, irregular, yellow lines. The whole shell is covered in these stripes and markings that aid in camouflaging an individual.
+
+ 
+These turtles also have a complete skeletal system, with partially webbed feet that help them to swim and that can be withdrawn inside the carapace along with the head and tail. The red stripe on each side of the head distinguishes the red-eared slider from all other North American species and gives this species its name, as the stripe is located behind the eyes, where their (external) ears would be. These stripes may lose their color over time. Some individuals can also have a small mark of the same color on the top of their heads. The red-eared slider does not have a visible outer ear or an external auditory canal; instead, it relies on a middle ear entirely covered by a cartilaginous tympanic disc.
+
+
+=== Sexual dimorphism ===
+
+Some dimorphism exists between males and females.Red-eared slider young look practically identical regardless of their sex, making distinguishing them difficult. One useful method, however, is to inspect the markings under their carapace, which fade as the turtles age. Distinguishing the sex of adults is much easier, as the shells of mature males are smaller than those of females. Male red-eared sliders reach sexual maturity when their carapaces' diameters measure 10 cm (3.9 in) and females reach maturity when their carapaces measure about 15 cm. Both males and females reach sexual maturity at 5–6 years old. Males are normally smaller than females, although this parameter is sometimes difficult to apply, as individuals being compared could be of different ages.
+Males have longer claws on their front feet than the females; this helps them to hold onto a female during mating, and is used during courtship displays. The males' tails are thicker and longer. Typically, the cloacal opening of a female is at or under the rear edge of the carapace, while the male's opening occurs beyond the edge of the carapace. The male's plastron is slightly concave, while that of the female is completely flat. The male's concave plastron also helps to stabilize the male on the female's carapace during mating. Older males can sometimes have a dark greyish-olive green melanistic coloration, with very subdued markings. The red stripe on the sides of the head may be difficult to see or be absent. The female's appearance is substantially the same throughout her life.
+
+
+== Distribution and habitat ==
+The red-eared slider originated from the area around the Mississippi River and the Gulf of Mexico, in warm climates in the Southeastern United States. Their native areas range from the southeast of Colorado to Virginia and Florida. In nature, they inhabit areas with a source of still, warm water, such as ponds, lakes, swamps, creeks, streams, or slow-flowing rivers.

+Courtship and mating activities for red-eared sliders usually occur between March and July, and take place under water. During courtship, the male swims around the female and flutters or vibrates the back side of his long claws on and around her face and head, possibly to direct pheromones towards her.

+The yellow-bellied slider (Trachemys scripta scripta) is a land and water turtle belonging to the family Emydidae. This subspecies of pond slider is native to the southeastern United States, specifically from Florida to southeastern Virginia, and is the most common turtle species in its range. It is found in a wide variety of habitats, including slow-moving rivers, floodplain swamps, marshes, seasonal wetlands, and permanent ponds. Yellow-bellied sliders are popular as pets.
+
+
+== Description ==
+Adult male yellow-bellied sliders typically reach 5–9 inches (13–23 cm) in length; females range from 8–13 inches (20–33 cm). The carapace (upper shell) is typically brown and black, often with yellow stripes. The skin is olive green with prominent patches of yellow down the neck and legs. As the name implies, the plastron (bottom shell) is mostly yellow with black spots along the edges. Adults tend to grow darker as they age. Yellow-bellied sliders are often confused with eastern river cooters, who also have yellow stripes on the neck and yellow undersides, but the latter lack the green spots characteristic of this species. The yellow belly often has an "s"-shaped yellow stripe on its face. They also have markings shaped like question marks on their bellies. Females of the species reach a larger body size than the males do in the same populations.
+
+Mating can occur in spring, summer, and autumn. They have polygynandrous mating behavior. Courtship consists of biting, foreclaw display, and chasing.  Yellow-bellied sliders are capable of interbreeding with other T. scripta subspecies, such as red-eared sliders, which are commonly sold as pets. The release of non-native red-eared sliders into local environments caused the state of Florida to ban the sale of red-eared sliders in order to protect the native population of yellow-bellied sliders.Yellow-bellied slider movement is highly instigated by dry seasons, where they can be found traveling terrestrially to locate a new water source. One study also found movement is also highly motivated by reproductive recruitment. Differences between male and female movements were observed. Males were more active than females in spring to the end of autumn. Males also exhibited more terrestrial and aquatic movements than females. Finally, long periods of movements were exclusively males.Mating takes place in the water. Suitable terrestrial area is required for egg-laying by nesting females, who will normally lay 6–10 eggs at a time, with larger females capable of bearing more. The eggs incubate for 2–3 months and the hatchlings will usually stay with the nest through winter. Hatchlings are almost entirely carnivorous, feeding on insects, spiders, crustaceans, tadpoles, fish, and carrion. As they age, adults eat less and less meat, and up to 95% of their nutritional intake eventually comes from plants.The slider is considered a diurnal turtle; it feeds mainly in the morning and frequently basks on shore, on logs, or while floating, during the rest of the day. At night, it sleeps on the bottom or on the surface near brush piles. Highest densities of sliders occur where algae blooms and aquatic macrophytes are abundant and are of the type that form dense mats at the surface, such as Myriophyllum spicatum and lily pads (Nymphaeaceae). Dense surface vegetation provides cover from predators and supports high densities of aquatic invertebrates and small vertebrates, which offer better foraging than open water.Some common predators of the yellow-bellied slider include raccoons, opossums, red foxes, and skunks. Other than predators, yellow-bellied sliders are susceptible to respiratory infections which can cause wheezing, drooling, or puffiness in the eyes and is commonly caused by bacteria.  Additionally, these turtles can develop fungal spores that can lead to shell rot, they can also develop metabolic bone disease which can stunt the growth of their shells and cause them to be more brittle and prone to damage The lifespan of yellow-bellied sliders is over 30 years in the wild, and over 40 years in captivity.Since yellow-bellied sliders are long-lived organisms, they require high survivorship to maintain stable populations. They are particularly susceptible to negative effects associated with anthropogenic habitat modification such as increased presence of human-subsidized predators and increased road mortality. Recruitment could also be decreased in populations in highly urbanized areas due to a decrease in habitat connectivity and potential nesting sites.
+
+
+== As pets ==
+
+
+=== Housing ===
+
+Baby yellow-bellied sliders may be kept in a fairly small tank (20 to 40 gallons), but as they age,  after about three years, they will require much more space. One adult may be housed in a 75 US gal (284 l) or larger aquarium. The turtles require enough water to turn around, with a depth of 16–18 in (41–46 cm) recommended. Water temperature should be kept between 72 and 80 °F (22–27 °C) and properly filtered. Keeping fish with turtles is usually avoided due to the risk that the turtle will eat the fish. Sliders need a basking area that is kept warm during the day and that will allow the turtle to move around, balance, and dry off completely. This area should average 89–95 °F (32–35 °C) and can be heated with a UV-A heat lamp. A second lamp that produces UV-B is absolutely essential for the turtle to metabolize calcium properly. Direct, unfiltered sunlight is preferable. The lamps should be switched on during daylight hours.
+
+
+=== Diet ===
+Pond plants such as elodea (anacharisan) and cabomba can also be left in the water, while human-consumed vegetables such as romaine lettuce, escarole and collard greens must be changed daily. As sliders are omnivores, insects and freshly killed fish may also be provided for protein. Commercially processed animal-based reptile food may be given too, but any sort of leftovers should be immediately removed to prevent fouling the water or turtle's habitat.

+The pond slider (Trachemys scripta) is a species of common, medium-sized, semiaquatic turtle. Three subspecies are described, the most recognizable of which is the red-eared slider (T. s. elegans), which is popular in the pet trade and has been introduced to other parts of the world by people releasing it to the wild. Hatchling and juvenile pond sliders have a green upper shell (carapace), yellow bottom shell (plastron), and green and yellow stripes and markings on their skin. These patterns and colors in the skin and shell fade with age until the carapace is a muted olive green to brown and the plastron is a dull yellow or darker. Some sliders become almost black with few visible markings.
+The carapace is oval with a bit of rounding and a central crest with knobs, but these features soften and fade with age, adults being smoother and flatter. For determining an adult slider's sex, males typically have much longer front claws than adult females, while females usually have shorter, more slender tails than males. Their lifespans range from 20 to 50 years.
+
+
+== Etymology ==
+The origin of the name slider stems from the behavior of these turtles when startled. Groups of sliders, sometimes quite large, as well as many other types of less abundant freshwater turtles, are often seen basking and sunning on logs, branches, and vegetation at or even well above the water's surface, but they readily and quickly scramble if they sense danger, shooting back in and darting away to safety underwater.
+
+
+== Distribution ==
+Pond sliders are native to the south-central and southeastern United States and northern Mexico.
+
+
+== Invasive species ==
+In the 1900s, many pond sliders were captured for sale. In the 1950s, millions of turtles were being farmed and shipped abroad as part of the pet trade.
+These turtles often compete with native species for food, habitat, and other resources. Eventually, they bully many native species out of basking sites, where sunlight (and warmth) is available for the species. When basking, pond sliders commonly bask on birds' nests, thereby killing the eggs. They also prey on young birds.
+Turtles that were raised in captivity can develop diseases that are unfamiliar to native species, which can be harmful. Turtles raised in captivity are often released because they become too much to handle or grow bigger than expected. Not uncommonly, they also escape.
+Conservationists have warned owners of turtles to not release them into the wild. Many states also have passed legislation to control the possession and release of pond sliders. Two states have completely banned the sale of these turtles.
+In Europe, T. script is included since 2016 in the list of Invasive Alien Species of Union concern (the Union list). This implies that this species cannot be imported, bred, transported, commercialized, or intentionally released into the environment in the whole of the European Union.
+
+
+== Subspecies ==
+
+T. s. scripta – yellow-bellied slider
+T. s. elegans – red-eared slider
+T. s.  troostii – Cumberland sliderHybridization between yellow-bellied and red-eared sliders is not uncommon where the ranges of the two subspecies overlap.

+The East Javan langur (Trachypithecus auratus), also known as the ebony lutung, Javan langur or Javan lutung, is an Old World monkey from the Colobinae subfamily. It is most commonly glossy black with a brownish tinge to its legs, sides, and "sideburns". It is found on the island of Java, as well as on several of the surrounding Indonesian islands. The Latin word auratus in its scientific name means "golden", and refers to a less common color variant. Note that the common name golden langur is used for a different species.
+Like all langurs, this species' tail is noticeably long, measuring up to 98 cm in length while the body is only around 55 cm long. The two subspecies of this lutung are fairly similar in appearance and are geographically separated; males and females are both usually glossy black, although the females pale, yellowish white patch around the pubic area. Juveniles of both subspecies are orange in color. The nominate subspecies Trachypithecus auratus auratus has a rare morph that does not lose its juvenile coloration when it matures, instead the coloration darkens slightly, with yellow tinges on its sides, limbs, and around its ears, and a black tinge on its back.The East Javan langur inhabits the interior and peripheral areas of rainforests.This primate is diurnal and arboreal. Its diet is primarily herbivorous, eating leaves, fruit, flowers, and flower buds, although it also eats insect larvae. As with other colobines, it has evolved a specialised stomach to digest plant material more efficiently. This species also has enlarged salivary glands to assist it in breaking down food.Like other langurs, the East Javan langur is a social animal, living in groups of around seven individuals, with one or two adult males in the group. Although they will look after offspring of other mothers as well as their own, adult females are aggressive towards females from other groups. The brighter coloring of juveniles may alert females to their presence and ensures that they will always be noticed and protected. This species has no discernible mating season and females produce one offspring at a time.

+The lowland nyala or simply nyala (Tragelaphus angasii) is a spiral-horned antelope native to southern Africa. It is a species of the family Bovidae and genus Tragelaphus, previously placed in genus Nyala. It was first described in 1849 by George French Angas. The body length is 135–195 cm (53–77 in), and it weighs 55–140 kg (121–309 lb). The coat is maroon or rufous brown in females and juveniles, but grows a dark brown or slate grey, often tinged with blue, in adult males. Females and young males have ten or more white stripes on their sides. Only males have horns, 60–83 cm (24–33 in) long and yellow-tipped. It exhibits the highest sexual dimorphism among the spiral-horned antelopes. It is not to be confused with the endangered mountain nyala living in the Bale region of Ethiopia).
+The nyala is mainly active in the early morning and the late afternoon. It generally browses during the day if temperatures are 20–30 °C (68–86 °F) and during the night in the rainy season. As a herbivore, the nyala feeds upon foliage, fruits and grasses, and requires sufficient fresh water. A shy animal, it prefers water holes rather than open spaces. The nyala does not show signs of territoriality, and individuals' areas can overlap. They are very cautious creatures. They live in single-sex or mixed family groups of up to 10 individuals, but old males live alone. They inhabit thickets within dense and dry savanna woodlands. The main predators of the nyala are lion, leopard and African wild dog, while baboons and raptorial birds prey on juveniles. Mating peaks during spring and autumn. Males and females are sexually mature at 18 and 11–12 months of age respectively, though they are socially immature until five years old. After a gestational period of seven months, a single calf is born.
+The nyala's range includes Malawi, Mozambique, South Africa, Eswatini, Zambia, and Zimbabwe. It has been introduced to Botswana and Namibia, and reintroduced to Eswatini, where it had been extinct since the 1950s. Its population is stable, and it has been listed as of least concern by the International Union for Conservation of Nature. The principal threats to the species are poaching and habitat loss resulting from human settlement. The males are highly prized as game animals in Africa.
+
+
+== Taxonomy and naming ==
+The nyala was first described by George French Angas, an English naturalist, in 1849. The scientific name of nyala is Tragelaphus angasii. The name angasii is attributed to Angas, who said that John Edward Gray had named this species after Angas' father, George Fife Angas of South Australia. According to Article 50.1.1 of the International Code of Zoological Nomenclature and International Commission on Zoological Nomenclature, though, this is insufficient to state Gray as the author. The name "nyala" is the Tsonga name for this antelope, which is likely the source of the English, along with Zulu inyala. Its first known use was in 1899. The word has a Bantu origin, similar to the Venda word dzì-nyálà (nyala buck).The nyala is the second taxon to branch off from the tragelaphine family tree just after the lesser kudu. As the nyala line has remained separate for a considerable time (over 5 million years), some authorities have placed it in its own monotypic genus Nyala. Nyala was proposed in 1912 by American zoologist Edmund Heller, who also proposed Ammelaphus for the lesser kudu, but it was not widely recognized. It was re-erected as a valid genus in 2011 under the classification of Peter Grubb and Colin Groves, but has not been embraced by taxonomic authorities such as the Mammal Diversity Database.
+
+In 2005, Sandi Willows-Munro (of the University of KwaZulu-Natal) and colleagues carried out a mitochondrial DNA analysis of the nine Tragelaphus species. Mitochondrial DNA and nuclear DNA data were compared. The results showed the tribe Tragelaphini to be monophyletic, with the lesser kudu (T. imberbis) basal in the phylogeny, followed by the nyala. On the basis of mitochondrial data, studies have estimated that the lesser kudu separated from its sister clade around 13.7 million years ago. However, nuclear DNA data shows lesser kudu and nyala forming a clade, which collectively separated from the sister clade 13.8 million years ago.
+
+
+=== Genetics and evolution ===
+The nyala has 55 male chromosomes and 56 female chromosomes. The Y chromosome has been translocated onto the 14th chromosome, as in other tragelaphids, but no inversion of the Y chromosome occurs. Cranial studies have shown that the mountain nyala and nyala, though sharing a common name, are actually distant relatives.Fossil evidence suggests that the nyala has been a separate species since the end of the Miocene (5.8 million years ago). Genetic evidence suggests that the proto-nyala had some early hybridization with the proto-lesser kudu, but the two have remained separate long after this crossing.
+
+
+== Physical description ==
+
+The nyala is a spiral-horned and middle-sized antelope, between a bushbuck and a kudu. It is considered the most sexually dimorphic antelope. The nyala is typically between 135–195 cm (53–77 in) in head-and-body length. The male stands up to 110 cm (43 in), the female is up to 90 cm (3.0 ft) tall. Males weigh 98–125 kg (216–276 lb), while females weigh 55–68 kg (121–150 lb). Life expectancy of the nyala is about 19 years.The coat is rusty or rufous brown in females and juveniles. It grows a dark brown or slate grey in adult males, often with a bluish tinge. Females and young males have ten or more white vertical stripes on their sides. Other markings are visible on the face, throat, flanks and thighs. Stripes are very reduced or absent in older males. Both males and females have a white chevron between their eyes, and a 40–55 cm (16–22 in) long bushy tail white underside. Both sexes have a dorsal crest of hair running right from the back of the head to the end of the tail. Males have another line of hair along the midline of their chest and belly.Only the males have horns. Horns are 60–83 cm (24–33 in) long and yellow-tipped. There are one or two twists. The spoor is similar to that of the bushbuck, but larger. It is 5–6 cm (2.0–2.4 in) long. The feces resemble round to spherical pellets. The nyala has hairy glands on its feet, which leave their scent wherever it walks.The condition of the nyala often varies between the sexes. According to a study, this can be attributed to the differences in their body sizes. It was noted that during nutritional stress, old adults died in more numbers, of which most were males. During an attempt of blood sampling in the nyala, it was found that Vitamin E levels varied during stress.
+
+
+== Parasites ==
+A study of the helminths from 77 nyalas from four game reserves in Natal revealed the presence of ten nematode species and four nematode genera, a trematode species and paramphistomes (members of superfamily Paramphistomoidea), and two cestode genera. The research discovered new parasites that the nyala was host of - namely a Cooperia rotundispiculum race, Gaigeria pachyscelis, a Gongylonema species, Haemonchus vegliai, Impalaia tuberculata, an Oesophagostomum species, a Setaria species, Trichostrongylus deflexus, Trichostrongylus falculatus, the larval stage of a Taenia species, a Thysaniezia species and Schistosoma mattheei. Ostertagia harrisi and C. rotundispiculum were the most dominant nematodes in the antelope.Another study of 97 blood samples of South African nyalas revealed the presence of tick-borne hemoparasites (blood parasites). The methods used were polymerase chain reaction (PCR) and reverse line blot (RLB) hybridization. The dominant parasites were Theileria species, T. buffeli, T. bicornis, Ehrlichia species, Anaplasma marginale and A. bovis. Ten tick species, two louse species and a louse fly species were recovered in a study of 73 nyalas at Umfolozi, Mkuzi and Ndumu Game Reserves in northeastern KwaZulu-Natal in 1983 and 1984 and an additional six individuals in 1994. It was found that nyalas were hosts to all stages of development in Boophilus decoloratus, Rhipicephalus appendiculatus and R. muehlensi and the immature stages of Amblyomma hebraeum and Rhipicephalus maculatus. Adult males served hosts to more number of ticks and lice than adult females did. Also, a trypanosome was isolated from a nyala, wild-caught in Mozambique, which was diagnosed and found as akin to Trypanosoma vivax, based on biological, morphological and molecular data.
+
+
+== Diseases ==
+
+The nyala can also suffer from myopathy. In between January 1973 and June 1981, 21 nyalas succumbed to the disease. The main symptoms were stiffness, inability to rise, and failure to suckle in newborns. Necrosis (that is, the premature death of cells in a living tissue) and mineralization were found in the skeletal muscle after a histological analysis. In the juveniles there was acute necrosis of the cardiac muscle. In adults, there was interstitial fibrosis of the cardiac muscle, along with arteriosclerosis.In a report published in 1994 entitled "Epidemiological observations on spongiform encephalopathies in captive wild animals in the British Isles", it was noted that spongiform encephalopathy had been diagnosed in one nyala captive in a zoo. The nyala was formerly affected by the disease rinderpest, although the viral disease is considered eradicated now.
+
+
+== Ecology and behavior ==
+
+The nyala is active mainly in the early morning and late afternoon. It browses during the day if temperatures are 20–30 °C (68–86 °F) and during the night in rainy season. These antelopes rest in thick bushes during the hot hours of the day. The nyala is very shy and cautious in nature, and often remains hidden rather than coming out in the open. Most sightings of the nyala in the wild are at water holes. But in protected areas they become less shy and often come out in view of tourists.Nyala groups are according to sex or mixed. Herds usually browse and drink water together. Each group consists of two to ten individuals. A study in Zinave National Park at Mozambique showed that 67% of the observations were of groups of one to three nyalas, and the rest of the herds consisted of up to 30 nyalas. Herds often broke up and re-formed. Generally adult males remain alone. Females often remain near their mothers when they have their offspring, so the relationships in female herds may be closer than those of males.Alert and wary in nature, the nyala use a sharp, high, dog-like bark to warn others in a group of danger. This feature is mainly used by females. They also react to the alarm calls of impala, baboon and kudu. The impala has been found to react to the calls of the nyala as well. The main predators of nyala are lion, leopard, cheetah, spotted hyena, African wild dog and nile crocodile while baboons and raptorial birds are predators of juveniles.
+
+
+=== Diet ===
+As a herbivore, the nyala's diet consists of foliage, fruits, flowers and twigs. During the rainy season they feed upon the fresh grass. They need a regular intake of water, and thus choose places with a water source nearby. However, they are adapted to live in areas with only a seasonal availability of water. A study in Zululand showed that the nyala fed mainly in the early morning and the late afternoon. They feed at night during the rainy season.A study in Mkhuze Game Reserve and Ndumu Game Reserve in Natal focused on the dietary habits of the impala and the nyala showed that the amount of dicotyledons in their diets varied seasonally. In the dry season, the nyala's dicotyledon diet content was 83.2% and the impala's 52%. In this season, the diet grew richer in fiber and dietary proteins were less. The reverse occurred in the rainy season. As the rainy season arrived, both species took to a diet of mainly monocotyledons, and the impala consumed more of them. The diet contained more proteins than fiber.Another study was done to find whether the sexual dimorphism in the nyala influenced its foraging habits. Vegetation surveys were conducted with the end of each feeding bout. It was found that females spent equal periods of time foraging in all the three habitats, but males preferred sand forest more. More differences were noted, as males ate woody species at a greater average height whereas females fed from the low herbaceous layer. It was concluded that the differences resulted from varying nutritional and energetic demands according to their diverse body sizes and differing reproductive strategies.
+
+
+=== Reproduction ===
+
+The nyala breeds throughout the year, but mating peaks in spring and autumn. The reason for this is still unknown, but attributed to the photoperiod and the feeding habits of the animal. Females reach sexual maturity at 11 to 12 months of age and males at 18 months (though they are socially immature until five years old), though they begin to show active spermatogenesis at 14 months.Before ovulation, the Graafian follicles reach a length of at least 6.7 cm (2.6 in). A female's estrous cycle is about 19 days long. Males will attempt to mate with the female for two days of the cycle, but she allows it for only six hours per cycle. When the male enters a females' herd during mating, he makes a display by raising his white dorsal crest, lowering his horns and moving stiffly. As in many other animals, the males fight over dominance during mating.The kidney fat indices (KFIs) of impalas and nyalas have been studied to understand the influence of social class and reproduction on them. To determine the KFI, the kidney is removed and weighed with the fat and once again excluding the fat. The resultant difference is the amount of fat on the kidney. The more the fat, the healthier the animal. In rut, male nyalas had lower KFIs, which did not vary much with the season. Pregnant females of both nyala and impala had higher KFIs than non-pregnant ones.There is a significant increase in corpus luteum in the last third of gestation. Gestation is of seven months. A single calf is born, weighing 5 kg (11 lb). Birth takes place generally away from the sight of predators, in places such as a thicket. The calf remains hidden for up to 18 days, and the mother nurses it at regular intervals. The calf remains with its mother until the birth of the next calf, during which males in rut drive it away from the mother.
+
+
+== Habitat and distribution ==
+
+The nyala inhabits dense lowland woodlands and thickets, mainly in southern Malawi, Mozambique, Zimbabwe, and eastern South Africa. It chooses places with good quality grasslands as well as provision of fresh water. It also inhabits lush green river country. The nyala's natural range stretches across southeast Africa from the Lower Shire Valley in Malawi through Mozambique and Zimbabwe to eastern South Africa and Eswatini.The geographic distribution of the nyala may be based on the genetic variation. According to a study of nyala in South Africa, Mozambique, Malawi and Zimbabwe, there was a marked difference in the gene frequencies at three microsatellite loci. Mitochondrial DNA analysis revealed the presence of a unique haplotype in individuals from each location. Thus, the geographic variation in the nyala may be due to a distribution pattern based on habitat specificity.Today nyala are found in South African protected areas in the Ndumo Game Reserve, uMkuze Game Reserve and Hluhluwe-Umfolozi Game Reserve, all in KwaZulu-Natal, as well as in Kruger National Park. As of 1999, 10–15% of nyala occurred on private land. Efforts are being made to retain the populations of nyala in Gorongosa National Park and Banhine National Park in Mozambique. Nyala also thrive in Lengwe National Park in Malawi.
+Nyala have never been observed showing territoriality. Territories of either sex overlap extensively. The home ranges of males are approximately equal to that of females, about 10 square kilometres (3.9 sq mi) in area.
+
+
+== Threats and conservation ==
+The major threats to the population of the nyala are poaching, habitat loss, agriculture and cattle grazing. Rinderpest outbreaks have also contributed in population loss. This species is currently of Least Concern, and the population is considered stable by both the IUCN and CITES. As of 1999, the total population of the nyala was around 32,000 individuals. More recent estimates show that South Africa has at least 30,000 nyalas, with 25,000 in KwaZulu-Natal. There are now more than 1,000 on protected areas and ranches in Eswatini. In Mozambique there are not more than 3,000, in Zimbabwe over 1,000, and numbers in Malawi have fallen from 3,000 to about 1,500. Namibia has the smallest population, at about 250.Today over 80% of the total population is protected in national parks and sanctuaries, mostly in South African protected areas. In South Africa there is a high demand for adult males as game trophies.

+The bongo (Tragelaphus eurycerus) is a herbivorous, mostly nocturnal forest ungulate. Bongos are characterised by a striking reddish-brown coat, black and white markings, white-yellow stripes and long slightly spiralled horns. They are the only tragelaphid in which both sexes have horns. They have a complex social interaction and are found in African dense forest mosaics. Native to Africa, they are the third-largest antelope in the world.The western or lowland bongo, T. e. eurycerus, faces an ongoing population decline, and the IUCN Antelope Specialist Group considers it to be Near Threatened on the conservation status scale.The eastern or mountain bongo, T. e. isaaci, of Kenya, has a coat even more vibrant than that of T. e. eurycerus. The mountain bongo is only found in the wild in a few mountain regions of central Kenya. This bongo is classified by the IUCN Antelope Specialist Group as Critically Endangered, with fewer individuals in the wild than in captivity (where it breeds readily).In 2000, the Association of Zoos and Aquariums in the USA (AZA) upgraded the bongo to a Species Survival Plan participant and in 2006 added the Bongo Restoration to Mount Kenya Project to its list of the Top Ten Wildlife Conservation Success Stories of the year. However, in 2013, it seems, these successes have been compromised by reports of possibly only 100 mountain bongos left in the wild due to logging and poaching.
+
+
+== Taxonomy ==
+The scientific name of the bongo is Tragelaphus eurycerus, and it belongs to the genus Tragelaphus and family Bovidae. It was first described by Irish naturalist William Ogilby in 1837. The generic name Tragelaphus is composed of two Greek words: trag-, meaning a goat; and elaphos, meaning deer. The specific name eurycerus originated from the fusion of eurus (broad, widespread) and keras (an animal's horn). The common name "bongo" originated probably from the Kele language of Gabon. The first known use of the name "bongo" in English dates to 1861.Bongos are further classified into two subspecies: T. e. eurycerus, the lowland or western bongo, and the far rarer T. e. isaaci, the mountain or eastern bongo, restricted to the mountains of Kenya only. The eastern bongo is larger and heavier than the western bongo. Two other subspecies are described from West and Central Africa, but taxonomic clarification is required. They have been observed to live up to 19 years.
+
+
+== Appearance ==
+
+Bongos are one of the largest of the forest antelopes. In addition to the deep chestnut colour of their coats, they have bright white stripes on their sides to help with camouflage.
+Adults of both sexes are similar in size. Adult height is about 1.1 to 1.3 m (3.6 to 4.3 ft) at the shoulder and length is 2.15 to 3.15 m (7.1 to 10.3 ft), including a tail of 45–65 cm (18–26 in). Females weigh around 150–235 kg (331–518 lb), while males weigh about 220–405 kg (485–893 lb). Its large size puts it as the third-largest in the Bovidae tribe of Strepsicerotini, behind both the common and greater elands by about 300 kg (660 lb), and above the greater kudu by about 40 kg (88 lb).Both sexes have heavy spiral horns; those of the male are longer and more massive. All bongos in captivity are from the isolated Aberdare Mountains of central Kenya.
+
+
+=== Coat and body ===
+ 
+The bongo sports a bright auburn or chestnut coat, with the neck, chest, and legs generally darker than the rest of the body. Coats of male bongos become darker as they age until they reach a dark mahogany-brown colour. Coats of female bongos are usually more brightly coloured than those of males. The eastern bongo is darker in color than the western and this is especially pronounced in older males which tend to be chestnut brown, especially on the forepart of their bodies.
+The pigmentation in the coat rubs off quite easily; anecdotal reports suggest rain running off a bongo may be tinted red with pigment. The smooth coat is marked with 10–15 vertical white-yellow stripes, spread along the back from the base of the neck to the rump. The number of stripes on each side is rarely the same. It also has a short, bristly, brown ridge of dorsal hair from the shoulder to the rump; the white stripes run into this ridge.
+A white chevron appears between the eyes, and two large white spots grace each cheek. Another white chevron occurs where the neck meets the chest. The large ears are to sharpen hearing, and the distinctive coloration may help bongos identify one another in their dark forest habitats. Bongos have no special secretion glands, so rely less on scent to find one another than do other similar antelopes. The lips of a bongo are white, topped with a black muzzle.
+
+
+=== Horns ===
+
+Bongos have two heavy and slightly spiralled horns that slope over their backs, and like many other antelope species, both male and female bongos have horns. Bongos are the only tragelaphids in which both sexes have horns. The horns of bongos are in the form of a lyre and bear a resemblance to those of the related antelope species of nyalas, sitatungas, bushbucks, kudus and elands.
+Unlike deer, which have branched antlers shed annually, bongos and other antelopes have pointed horns they keep throughout their lives. Males have massive backswept horns, while females have smaller, thinner, and more parallel horns. The size of the horns range between 75 and 99 cm (29.5 and 39 in). The horns twist once.
+Like all other horns of antelopes, the core of a bongo's horn is hollow and the outer layer of the horn is made of keratin, the same material that makes up human fingernails, toenails and hair. The bongo runs gracefully and at full speed through even the thickest tangles of lianas, laying its heavy spiralled horns on its back so the brush cannot impede its flight. Bongos are hunted for their horns by humans.
+
+
+== Social organization and behavior ==
+
+Like other forest ungulates, bongos are seldom seen in large groups. Males, called bulls, tend to be solitary, while females with young live in groups of six to eight. Bongos have seldom been seen in herds of more than 20. Gestation is about 285 days (9.5 months), with one young per birth, and weaning occurs at six months. Sexual maturity is reached at 24–27 months. The preferred habitat of this species is so dense and difficult to operate in, that few Europeans or Americans observed this species until the 1960s.
+As young males mature and leave their maternal groups, they most often remain solitary, although rarely they join an older male. Adult males of similar size/age tend to avoid one another. Occasionally, they meet and spar with their horns in a ritualised manner and it is rare for serious fights to take place. However, such fights are usually discouraged by visual displays, in which the males bulge their necks, roll their eyes, and hold their horns in a vertical position while slowly pacing back and forth in front of the other male. They seek out females only during mating time. When they are with a herd of females, males do not coerce them or try to restrict their movements as do some other antelopes.
+Although mostly nocturnal, they are occasionally active during the day. However, like deer, bongos may exhibit crepuscular behaviour. Bongos are both timid and easily frightened; after a scare, a bongo moves away at considerable speed, even through dense undergrowth. Once they find cover, they stay alert and face away from the disturbance, but peek every now and then to check the situation. The bongo's hindquarters are less conspicuous than the forequarters, and from this position the animal can quickly flee.
+When in distress, the bongo emits a bleat. It uses a limited number of vocalisations, mostly grunts and snorts; females have a weak mooing contact-call for their young. Females prefer to use traditional calving grounds restricted to certain areas, while newborn calves lie in hiding for a week or more, receiving short visits by the mother to suckle.The calves grow rapidly and can soon accompany their mothers in the nursery herds. Their horns grow rapidly and begin to show in 3.5 months. They are weaned after six months and reach sexual maturity at about 20 months.
+
+
+== Ecology ==
+
+
+=== Distribution and habitat ===
+Bongos are found in tropical jungles with dense undergrowth up to an altitude of 4,000 meters (13,000 feet) in Central Africa, with isolated populations in Kenya, and these West African countries: Cameroon, the Central African Republic, the Republic of the Congo, the Democratic Republic of Congo, the Ivory Coast, Equatorial Guinea, Gabon, Ghana, Guinea, Liberia, Sierra Leone, South Sudan.
+
+Historically, bongos are found in three disjunct parts of Africa: East, Central and West. Today, all three populations' ranges have shrunk in size due to habitat loss for agriculture and uncontrolled timber cutting, as well as hunting for meat.
+Bongos favour disturbed forest mosaics that provide fresh, low-level green vegetation.   Such habitats may be promoted by heavy browsing by elephants, fires, flooding, tree-felling (natural or by logging), and fallowing. Mass bamboo die-off provides ideal habitat in East Africa. They can live in bamboo forests.
+
+
+=== Diet ===
+
+Like many forest ungulates, bongos are herbivorous browsers and feed on leaves, bushes, vines, bark and pith of rotting trees, grasses/herbs, roots, cereals, and fruits.
+Bongos require salt in their diets, and are known to regularly visit natural salt licks. Bongos are also known to eat burnt wood after a storm, as a rich source of salt and minerals. This behavior is believed to be a means of getting salts and minerals into their diets. This behavior has also been reported in the okapi. Another similarity to the okapi, though the bongo is unrelated, is that the bongo has a long prehensile tongue which it uses to grasp grasses and leaves.
+Suitable habitats for bongos must have permanent water available. As a large animal, the bongo requires an ample amount of food, and is restricted to areas with abundant year-round growth of herbs and low shrubs.
+
+
+== Population and conservation ==
+Few estimates of population density are available. Assuming average population densities of 0.25 animals per km2 in regions where it is known to be common or abundant, and 0.02 per km2 elsewhere, and with a total area of occupancy of 327,000 km2, a total population estimate of around 28,000 is suggested. Only about 60% are in protected areas, suggesting the actual numbers of the lowland subspecies may only be in the low tens of thousands. In Kenya, their numbers have declined significantly and on Mount Kenya, they were extirpated within the last decade due to illegal hunting with dogs. Although information on their status in the wild is lacking, lowland bongos are not presently considered endangered.
+Bongos are susceptible to diseases such as rinderpest, which almost exterminated the species during the 1890s. Tragelaphus eurycerus may suffer from goitre. Over the course of the disease, the thyroid glands greatly enlarge (up to 10 x 20 cm) and may become polycystic. Pathogenesis of goiter in the bongo may reflect a mixture of genetic predisposition coupled with environmental factors, including a period of exposure to a goitrogen. Leopards and spotted hyenas are the primary natural predators (lions are seldom encountered due to differing habitat preferences); pythons sometimes eat bongo calves. Humans prey on them for their pelts, horns, and meat, with the species being a common local source for "bush meat". Bongo populations have been greatly reduced by hunting, poaching, and animal trapping, although some bongo refuges exist.
+Although bongos are quite easy for humans to catch using snares, many people native to the bongos' habitat believed that if they ate or touched bongo, they would have spasms similar to epileptic seizures. Because of this superstition, bongos were less harmed in their native ranges than expected. However, these taboos are said no longer to exist, which may account for increased hunting by humans in recent times.
+
+
+=== Zoo programmes ===
+ 
+An international studbook is maintained to help manage animals held in captivity. Because of its bright colour, it is very popular in zoos and private collections. In North America, over 400 individuals are thought to be held, a population that probably exceeds that of the mountain bongo in the wild.
+In 2000, the Association of Zoos and Aquariums (AZA) upgraded the bongo to a Species Survival Plan participant, which works to improve the genetic diversity of managed animal populations. The target population for participating zoos and private collections in North America is 250 animals. Through the efforts of zoos in North America, a reintroduction to the population in Kenya is being developed.
+At least one collaborative effort for reintroduction between North American wildlife facilities has already been carried out. In 2004, 18 eastern bongos born in North American zoos gathered at White Oak Conservation in Yulee, Florida for release in Kenya. White Oak staff members traveled with the bongos to a Mount Kenya holding facility, where they stayed until being reintroduced.
+
+
+=== Conservation ===
+In the last few decades, a rapid decline in the numbers of wild mountain bongo has occurred due to poaching and human pressure on their habitat, with local extinctions reported in Cherangani and Chepalungu hills, Kenya.
+The Bongo Surveillance Programme, working alongside the Kenya Wildlife Service, have recorded photos of bongos at remote salt licks in the Aberdare Forests using camera traps, and, by analyzing DNA extracted from dung, have confirmed the presence of bongo in Mount Kenya, Eburru and Mau forests. The programme estimate as few as 140 animals left in the wild – spread across four isolated populations. Whilst captive breeding programmes can be viewed as having been successful in ensuring survival of this species in Europe and North America, the situation in the wild has been less promising. Evidence exists of bongo surviving in Kenya. However, these populations are believed to be small, fragmented, and vulnerable to extinction.
+Animal populations with impoverished genetic diversity are inherently less able to adapt to changes in their environments (such as climate change, disease outbreaks, habitat change, etc.). The isolation of the four remaining small bongo populations, which themselves would appear to be in decline, means a substantial amount of genetic material is lost each generation. Whilst the population remains small, the impact of transfers will be greater, so the establishment of a "metapopulation management plan" occurs concurrently with conservation initiatives to enhance in situ population growth, and this initiative is both urgent and fundamental to the future survival of mountain bongo in the wild.
+The western/lowland bongo faces an ongoing population decline as habitat destruction and hunting pressures increase with the relentless expansion of human settlement. Its long-term survival will only be assured in areas which receive active protection and management. At present, such areas comprise about 30,000 km2, and several are in countries where political stability is fragile. So, a realistic possibility exists whereby its status could decline to Threatened in the near future.
+As the largest and most spectacular forest antelope, the western/lowland bongo is both an important flagship species for protected areas such as national parks, and a major trophy species which has been taken in increasing numbers in Central Africa by sport hunters during the 1990s. Both of these factors are strong incentives to provide effective protection and management of populations.
+
+Trophy hunting has the potential to provide economic justification for the preservation of larger areas of bongo habitat than national parks, especially in remote regions of Central Africa, where possibilities for commercially successful tourism are very limited.The eastern/mountain bongo's survival in the wild is dependent on more effective protection of the surviving remnant populations in Kenya. If this does not occur, it will eventually become extinct in the wild. The existence of a healthy captive population of this subspecies offers the potential for its reintroduction.
+
+
+=== Groups supporting bongo conservation in Kenya ===
+In 2004, Dr. Jake Veasey, the head of the Department of Animal Management and Conservation at Woburn Safari Park and a member of the European Association of Zoos and Aquariums Population Management Advisory Group, with the assistance of Lindsay Banks, took over responsibility for the management and coordination of the European Endangered Species Programme for the eastern bongo. This includes some 250 animals across Europe and the Middle East.
+Along with the Rothschild giraffe, the eastern bongo is arguably one of the most threatened large mammals in Africa, with recent estimates numbering less than 140 animals, below a minimum sustainable viable population. The situation is exacerbated because these animals are spread across four isolated populations. Whilst the bongo endangered species program can be viewed as having been successful in ensuring survival of this species in Europe, it has not yet become actively involved in the conservation of this species in the wild in a coordinated fashion. The plan is to engage in conservation activities in Kenya to assist in reversing the decline of the eastern bongo populations and genetic diversity in Africa, and in particular, applying population management expertise to help ensure the persistence of genetic diversity in the free ranging wild populations.
+
+To illustrate significance of genetic diversity loss, assume the average metapopulation size is 35 animals based on 140 animals spread across four populations (140/4=35). Assuming stable populations, these populations will lose 8% of their genetic diversity every decade. By managing all four populations as one, through strategic transfers, gene loss is reduced from 8% to 2% per decade, without any increase in bongo numbers in Kenya. By managing the European and African populations as one – by strategic exports from Europe combined with in situ transfers, gene loss is reduced to 0.72% every 100 years, with both populations remaining stable. If populations in Kenya are allowed to grow through the implementation of effective conservation, including strategic transfers, gene loss can be effectively halted in this species and its future secured in the wild.
+The initial aims of the project are: 
+
+Through faecal DNA analysis, estimate the genetic diversity of the remaining wild bongos and calculate the relatedness of the isolated wild populations.
+More accurately estimate the total population of wild bongos through faecal DNA analysis, camera trapping, and transect surveying.
+Through direct sampling, estimate the genetic diversity of the captive bongo population and calculate its relatedness with the remaining isolated wild populations.
+Collect DNA samples from western bongos to calculate the relatedness of the two subspecies.
+Fund rangers to collect the above data in Kenya, enhance the degree of protection afforded to and level of understanding of the eastern bongos' ecological needs.
+To realise such a metapopulation management plan, work with local communities is essential to reverse the decline and allow for the implementation of a transfer strategy. A substantial proportion of wild genetic diversity likely will have already been lost.If effective protection were implemented immediately and bongo populations allowed to expand without transfers, then this would create a bigger population of genetically impoverished bongos. These animals would be less able to adapt to a dynamic environment. Whilst the population remains small, the impact of transfers will be greater. For this reason, the 'metapopulation management plan' must occur concurrently with conservation strategies to enhance in situ population growth. This initiative is both urgent and fundamental to the future survival of the mountain bongo in the wild.
+In 2013, SafariCom telecommunications donated money to the Bongo Surveillance Programme to try to keep tabs on what are thought to be the last 100 eastern bongos left in the wild in the Mau Eburu Forest in central Kenya, whose numbers are still declining due to logging of their habitat and illegal poaching.Mount Kenya Wildlife Conservancy runs a bongo rehabilitation program in collaboration with the Kenya Wildlife Service. The Conservancy aims to prevent extinction of the bongo through breeding and release back into the wild.
+
+
+== Status ==
+The IUCN Antelope Specialist Group considers the western or lowland bongo, T. e. eurycerus, to be Lower Risk (Near Threatened) and the eastern or mountain bongo, T. e. isaaci, of Kenya, to be Critically Endangered. These bongos may be endangered due to human environmental interaction, as well as hunting and illegal actions towards wildlife.
+CITES lists bongos as an Appendix III species, only regulating their exportation from a single country, Ghana. It is not protected by the US Endangered Species Act and is not listed by the USFWS.

The first known use of the name "bongo" in English dates to 1861.Bongos are further classified into two subspecies: T. e. eurycerus, the lowland or western bongo, and the far rarer T. e. isaaci, the mountain or eastern bongo, restricted to the mountains of Kenya only. The eastern bongo is larger and heavier than the western bongo. Two other subspecies are described from West and Central Africa, but taxonomic clarification is required. They have been observed to live up to 19 years.
+
+
+== Appearance ==
+
+Bongos are one of the largest of the forest antelopes. In addition to the deep chestnut colour of their coats, they have bright white stripes on their sides to help with camouflage.
+Adults of both sexes are similar in size. Adult height is about 1.1 to 1.3 m (3.6 to 4.3 ft) at the shoulder and length is 2.15 to 3.15 m (7.1 to 10.3 ft), including a tail of 45–65 cm (18–26 in). Females weigh around 150–235 kg (331–518 lb), while males weigh about 220–405 kg (485–893 lb). Its large size puts it as the third-largest in the Bovidae tribe of Strepsicerotini, behind both the common and greater elands by about 300 kg (660 lb), and above the greater kudu by about 40 kg (88 lb).Both sexes have heavy spiral horns; those of the male are longer and more massive. All bongos in captivity are from the isolated Aberdare Mountains of central Kenya.
+
+
+=== Coat and body ===
+ 
+The bongo sports a bright auburn or chestnut coat, with the neck, chest, and legs generally darker than the rest of the body. Coats of male bongos become darker as they age until they reach a dark mahogany-brown colour. Coats of female bongos are usually more brightly coloured than those of males. The eastern bongo is darker in color than the western and this is especially pronounced in older males which tend to be chestnut brown, especially on the forepart of their bodies.
+The pigmentation in the coat rubs off quite easily; anecdotal reports suggest rain running off a bongo may be tinted red with pigment. The smooth coat is marked with 10–15 vertical white-yellow stripes, spread along the back from the base of the neck to the rump. The number of stripes on each side is rarely the same. It also has a short, bristly, brown ridge of dorsal hair from the shoulder to the rump; the white stripes run into this ridge.
+A white chevron appears between the eyes, and two large white spots grace each cheek. Another white chevron occurs where the neck meets the chest. The large ears are to sharpen hearing, and the distinctive coloration may help bongos identify one another in their dark forest habitats. Bongos have no special secretion glands, so rely less on scent to find one another than do other similar antelopes. The lips of a bongo are white, topped with a black muzzle.
+
+
+=== Horns ===
+
+Bongos have two heavy and slightly spiralled horns that slope over their backs, and like many other antelope species, both male and female bongos have horns. Bongos are the only tragelaphids in which both sexes have horns. The horns of bongos are in the form of a lyre and bear a resemblance to those of the related antelope species of nyalas, sitatungas, bushbucks, kudus and elands.
+Unlike deer, which have branched antlers shed annually, bongos and other antelopes have pointed horns they keep throughout their lives. Males have massive backswept horns, while females have smaller, thinner, and more parallel horns. The size of the horns range between 75 and 99 cm (29.5 and 39 in). The horns twist once.
+Like all other horns of antelopes, the core of a bongo's horn is hollow and the outer layer of the horn is made of keratin, the same material that makes up human fingernails, toenails and hair. The bongo runs gracefully and at full speed through even the thickest tangles of lianas, laying its heavy spiralled horns on its back so the brush cannot impede its flight. Bongos are hunted for their horns by humans.
+
+
+== Social organization and behavior ==
+
+Like other forest ungulates, bongos are seldom seen in large groups. Males, called bulls, tend to be solitary, while females with young live in groups of six to eight. Bongos have seldom been seen in herds of more than 20. Gestation is about 285 days (9.5 months), with one young per birth, and weaning occurs at six months. Sexual maturity is reached at 24–27 months. The preferred habitat of this species is so dense and difficult to operate in, that few Europeans or Americans observed this species until the 1960s.
+As young males mature and leave their maternal groups, they most often remain solitary, although rarely they join an older male. Adult males of similar size/age tend to avoid one another. Occasionally, they meet and spar with their horns in a ritualised manner and it is rare for serious fights to take place. However, such fights are usually discouraged by visual displays, in which the males bulge their necks, roll their eyes, and hold their horns in a vertical position while slowly pacing back and forth in front of the other male. They seek out females only during mating time. When they are with a herd of females, males do not coerce them or try to restrict their movements as do some other antelopes.
+Although mostly nocturnal, they are occasionally active during the day. However, like deer, bongos may exhibit crepuscular behaviour. Bongos are both timid and easily frightened; after a scare, a bongo moves away at considerable speed, even through dense undergrowth. Once they find cover, they stay alert and face away from the disturbance, but peek every now and then to check the situation. The bongo's hindquarters are less conspicuous than the forequarters, and from this position the animal can quickly flee.
+When in distress, the bongo emits a bleat. It uses a limited number of vocalisations, mostly grunts and snorts; females have a weak mooing contact-call for their young. Females prefer to use traditional calving grounds restricted to certain areas, while newborn calves lie in hiding for a week or more, receiving short visits by the mother to suckle.The calves grow rapidly and can soon accompany their mothers in the nursery herds. Their horns grow rapidly and begin to show in 3.5 months. They are weaned after six months and reach sexual maturity at about 20 months.
+
+
+== Ecology ==
+
+
+=== Distribution and habitat ===
+Bongos are found in tropical jungles with dense undergrowth up to an altitude of 4,000 meters (13,000 feet) in Central Africa, with isolated populations in Kenya, and these West African countries: Cameroon, the Central African Republic, the Republic of the Congo, the Democratic Republic of Congo, the Ivory Coast, Equatorial Guinea, Gabon, Ghana, Guinea, Liberia, Sierra Leone, South Sudan.
+
+Historically, bongos are found in three disjunct parts of Africa: East, Central and West. Today, all three populations' ranges have shrunk in size due to habitat loss for agriculture and uncontrolled timber cutting, as well as hunting for meat.
+Bongos favour disturbed forest mosaics that provide fresh, low-level green vegetation.   Such habitats may be promoted by heavy browsing by elephants, fires, flooding, tree-felling (natural or by logging), and fallowing. Mass bamboo die-off provides ideal habitat in East Africa. They can live in bamboo forests.
+
+
+=== Diet ===
+
+Like many forest ungulates, bongos are herbivorous browsers and feed on leaves, bushes, vines, bark and pith of rotting trees, grasses/herbs, roots, cereals, and fruits.
+Bongos require salt in their diets, and are known to regularly visit natural salt licks. Bongos are also known to eat burnt wood after a storm, as a rich source of salt and minerals. This behavior is believed to be a means of getting salts and minerals into their diets. This behavior has also been reported in the okapi. Another similarity to the okapi, though the bongo is unrelated, is that the bongo has a long prehensile tongue which it uses to grasp grasses and leaves.
+Suitable habitats for bongos must have permanent water available. As a large animal, the bongo requires an ample amount of food, and is restricted to areas with abundant year-round growth of herbs and low shrubs.
+
+
+== Population and conservation ==
+Few estimates of population density are available. Assuming average population densities of 0.25 animals per km2 in regions where it is known to be common or abundant, and 0.02 per km2 elsewhere, and with a total area of occupancy of 327,000 km2, a total population estimate of around 28,000 is suggested. Only about 60% are in protected areas, suggesting the actual numbers of the lowland subspecies may only be in the low tens of thousands. In Kenya, their numbers have declined significantly and on Mount Kenya, they were extirpated within the last decade due to illegal hunting with dogs. Although information on their status in the wild is lacking, lowland bongos are not presently considered endangered.
+Bongos are susceptible to diseases such as rinderpest, which almost exterminated the species during the 1890s. Tragelaphus eurycerus may suffer from goitre. Over the course of the disease, the thyroid glands greatly enlarge (up to 10 x 20 cm) and may become polycystic. Pathogenesis of goiter in the bongo may reflect a mixture of genetic predisposition coupled with environmental factors, including a period of exposure to a goitrogen. Leopards and spotted hyenas are the primary natural predators (lions are seldom encountered due to differing habitat preferences); pythons sometimes eat bongo calves. Humans prey on them for their pelts, horns, and meat, with the species being a common local source for "bush meat". Bongo populations have been greatly reduced by hunting, poaching, and animal trapping, although some bongo refuges exist.
+Although bongos are quite easy for humans to catch using snares, many people native to the bongos' habitat believed that if they ate or touched bongo, they would have spasms similar to epileptic seizures. Because of this superstition, bongos were less harmed in their native ranges than expected. However, these taboos are said no longer to exist, which may account for increased hunting by humans in recent times.
+
+
+=== Zoo programmes ===
+ 
+An international studbook is maintained to help manage animals held in captivity. Because of its bright colour, it is very popular in zoos and private collections. In North America, over 400 individuals are thought to be held, a population that probably exceeds that of the mountain bongo in the wild.
+In 2000, the Association of Zoos and Aquariums (AZA) upgraded the bongo to a Species Survival Plan participant, which works to improve the genetic diversity of managed animal populations. The target population for participating zoos and private collections in North America is 250 animals. Through the efforts of zoos in North America, a reintroduction to the population in Kenya is being developed.
+At least one collaborative effort for reintroduction between North American wildlife facilities has already been carried out. In 2004, 18 eastern bongos born in North American zoos gathered at White Oak Conservation in Yulee, Florida for release in Kenya. White Oak staff members traveled with the bongos to a Mount Kenya holding facility, where they stayed until being reintroduced.
+
+
+=== Conservation ===
+In the last few decades, a rapid decline in the numbers of wild mountain bongo has occurred due to poaching and human pressure on their habitat, with local extinctions reported in Cherangani and Chepalungu hills, Kenya.
+The Bongo Surveillance Programme, working alongside the Kenya Wildlife Service, have recorded photos of bongos at remote salt licks in the Aberdare Forests using camera traps, and, by analyzing DNA extracted from dung, have confirmed the presence of bongo in Mount Kenya, Eburru and Mau forests. The programme estimate as few as 140 animals left in the wild – spread across four isolated populations. Whilst captive breeding programmes can be viewed as having been successful in ensuring survival of this species in Europe and North America, the situation in the wild has been less promising. Evidence exists of bongo surviving in Kenya. However, these populations are believed to be small, fragmented, and vulnerable to extinction.
+Animal populations with impoverished genetic diversity are inherently less able to adapt to changes in their environments (such as climate change, disease outbreaks, habitat change, etc.). The isolation of the four remaining small bongo populations, which themselves would appear to be in decline, means a substantial amount of genetic material is lost each generation. Whilst the population remains small, the impact of transfers will be greater, so the establishment of a "metapopulation management plan" occurs concurrently with conservation initiatives to enhance in situ population growth, and this initiative is both urgent and fundamental to the future survival of mountain bongo in the wild.
+The western/lowland bongo faces an ongoing population decline as habitat destruction and hunting pressures increase with the relentless expansion of human settlement. Its long-term survival will only be assured in areas which receive active protection and management. At present, such areas comprise about 30,000 km2, and several are in countries where political stability is fragile. So, a realistic possibility exists whereby its status could decline to Threatened in the near future.
+As the largest and most spectacular forest antelope, the western/lowland bongo is both an important flagship species for protected areas such as national parks, and a major trophy species which has been taken in increasing numbers in Central Africa by sport hunters during the 1990s. Both of these factors are strong incentives to provide effective protection and management of populations.
+
+Trophy hunting has the potential to provide economic justification for the preservation of larger areas of bongo habitat than national parks, especially in remote regions of Central Africa, where possibilities for commercially successful tourism are very limited.The eastern/mountain bongo's survival in the wild is dependent on more effective protection of the surviving remnant populations in Kenya. If this does not occur, it will eventually become extinct in the wild. The existence of a healthy captive population of this subspecies offers the potential for its reintroduction.
+
+
+=== Groups supporting bongo conservation in Kenya ===
+In 2004, Dr. Jake Veasey, the head of the Department of Animal Management and Conservation at Woburn Safari Park and a member of the European Association of Zoos and Aquariums Population Management Advisory Group, with the assistance of Lindsay Banks, took over responsibility for the management and coordination of the European Endangered Species Programme for the eastern bongo. This includes some 250 animals across Europe and the Middle East.
+Along with the Rothschild giraffe, the eastern bongo is arguably one of the most threatened large mammals in Africa, with recent estimates numbering less than 140 animals, below a minimum sustainable viable population. The situation is exacerbated because these animals are spread across four isolated populations. Whilst the bongo endangered species program can be viewed as having been successful in ensuring survival of this species in Europe, it has not yet become actively involved in the conservation of this species in the wild in a coordinated fashion. The plan is to engage in conservation activities in Kenya to assist in reversing the decline of the eastern bongo populations and genetic diversity in Africa, and in particular, applying population management expertise to help ensure the persistence of genetic diversity in the free ranging wild populations.
+
+To illustrate significance of genetic diversity loss, assume the average metapopulation size is 35 animals based on 140 animals spread across four populations (140/4=35). Assuming stable populations, these populations will lose 8% of their genetic diversity every decade. By managing all four populations as one, through strategic transfers, gene loss is reduced from 8% to 2% per decade, without any increase in bongo numbers in Kenya. By managing the European and African populations as one – by strategic exports from Europe combined with in situ transfers, gene loss is reduced to 0.72% every 100 years, with both populations remaining stable. If populations in Kenya are allowed to grow through the implementation of effective conservation, including strategic transfers, gene loss can be effectively halted in this species and its future secured in the wild.
+The initial aims of the project are: 
+
+Through faecal DNA analysis, estimate the genetic diversity of the remaining wild bongos and calculate the relatedness of the isolated wild populations.
+More accurately estimate the total population of wild bongos through faecal DNA analysis, camera trapping, and transect surveying.
+Through direct sampling, estimate the genetic diversity of the captive bongo population and calculate its relatedness with the remaining isolated wild populations.
+Collect DNA samples from western bongos to calculate the relatedness of the two subspecies.
+Fund rangers to collect the above data in Kenya, enhance the degree of protection afforded to and level of understanding of the eastern bongos' ecological needs.
+To realise such a metapopulation management plan, work with local communities is essential to reverse the decline and allow for the implementation of a transfer strategy. A substantial proportion of wild genetic diversity likely will have already been lost.If effective protection were implemented immediately and bongo populations allowed to expand without transfers, then this would create a bigger population of genetically impoverished bongos. These animals would be less able to adapt to a dynamic environment. Whilst the population remains small, the impact of transfers will be greater. For this reason, the 'metapopulation management plan' must occur concurrently with conservation strategies to enhance in situ population growth. This initiative is both urgent and fundamental to the future survival of the mountain bongo in the wild.
+In 2013, SafariCom telecommunications donated money to the Bongo Surveillance Programme to try to keep tabs on what are thought to be the last 100 eastern bongos left in the wild in the Mau Eburu Forest in central Kenya, whose numbers are still declining due to logging of their habitat and illegal poaching.Mount Kenya Wildlife Conservancy runs a bongo rehabilitation program in collaboration with the Kenya Wildlife Service. The Conservancy aims to prevent extinction of the bongo through breeding and release back into the wild.
+
+
+== Status ==
+The IUCN Antelope Specialist Group considers the western or lowland bongo, T. e. eurycerus, to be Lower Risk (Near Threatened) and the eastern or mountain bongo, T. e. isaaci, of Kenya, to be Critically Endangered. These bongos may be endangered due to human environmental interaction, as well as hunting and illegal actions towards wildlife.
+CITES lists bongos as an Appendix III species, only regulating their exportation from a single country, Ghana. It is not protected by the US Endangered Species Act and is not listed by the USFWS.

+The common eland (Taurotragus oryx), also known as the southern eland or eland antelope, is a savannah and plains antelope found in East and Southern Africa. It is a species of the family Bovidae and genus Taurotragus. An adult male is around 1.6 m (5 ft) tall at the shoulder (females are 20 cm (1 ft) shorter) and can weigh up to 942 kg (2,077 lb) with a typical range of 500–600 kg (1,100–1,300 lb), 340–445 kg (750–981 lb) for females). It is the second-largest antelope in the world, being slightly smaller on average than the giant eland. It was scientifically described by Peter Simon Pallas in 1766.
+Mainly a herbivore, its diet is primarily grasses and leaves. Common elands form herds of up to 500 animals, but are not territorial. The common eland prefers habitats with a wide variety of flowering plants such as savannah, woodlands, and open and montane grasslands; it avoids dense forests. It uses loud barks, visual and postural movements, and the flehmen response to communicate and warn others of danger. The common eland is used by humans for leather, meat, and milk, and has been domesticated in many areas. Eland milk contains more butterfat than cow's milk, and can keep longer without pasteurising.It is native to Angola, Botswana, the Democratic Republic of the Congo, Eswatini, Ethiopia, Kenya, Lesotho, Malawi, Mozambique, Namibia, Rwanda, South Africa, South Sudan, Tanzania, Uganda, Zambia, and Zimbabwe, but is no longer present in Burundi. While the common eland's population is decreasing, it is classified as of least concern by the International Union for Conservation of Nature.
+
+
+== Etymology ==
+The scientific name of the common eland is Taurotragus oryx, composed of three words: tauros, tragos, and oryx. Tauros is Greek for a bull or bullock, meaning the same as the Latin taurus. Tragos is Greek for a male goat, referring to the tuft of hair that grows in the eland's ear and its resemblance to a goat's beard. Oryx is Latin and Greek (genitive: orygos) for pickaxe, referring to the pointed horns of North African antelopes like the common eland and scimitar-horned oryx.The name "eland" is Dutch for "elk" or "moose". It has a Baltic source similar to the Lithuanian élnis, which means "deer". It was borrowed earlier as ellan (French) in the 1610s or Elend (German). When Dutch settlers came to the Cape of Good Hope, creating the Dutch Cape Colony, they named the animal after the large, herbivorous moose. In Dutch, the animal is called "eland antelope" to distinguish it from the moose, which is found in the northern boreal forests.
+
+
+== Physical description ==
+
+Common elands are spiral-horned antelopes. They are sexually dimorphic, with females being smaller than the males. Females weigh 300–600 kg (660–1,320 lb), measure 200–280 cm (79–110 in) from the snout to the base of the tail and stand 125–153 cm (49–60 in) at the shoulder. Bulls weigh 400–942 kg (882–2,077 lb), are 240–345 cm (94–136 in) from the snout to the base of the tail and stand 150–183 cm (59–72 in) at the shoulder. The tail is 50–90 cm (20–35 in) long. Male elands can weigh up to 1,000 kg (2,200 lb).
+
+Their coat differs geographically, with elands in northern part of their range having distinctive markings (torso stripes, markings on legs, dark garters and a spinal crest) that are absent in the south. Apart from a rough mane, the coat is smooth. Females have a tan coat, while the coats of males are darker, with a bluish-grey tinge. Bulls may also have a series of vertical white stripes on their sides (mainly in parts of the Karoo in South Africa). As males age, their coat becomes more grey. Males also have dense fur on their foreheads and a large dewlap on their throats.Both sexes have horns with a steady spiral ridge (resembling that of the bushbuck). The horns are visible as small buds in newborns and grow rapidly during the first seven months. The horns of males are thicker and shorter than those of females (males' horns are 43–66 centimetres (17–26 in) long and females' are 51–69 centimetres (20–27 in) long), and have a tighter spiral. Males use their horns during rutting season to wrestle and butt heads with rivals, while females use their horns to protect their young from predators.The common eland is the slowest antelope, with a peak speed of 40 km/h (25 mph) that tires them quickly. However, they can maintain a 22 km/h (14 mph) trot indefinitely. Elands are capable of jumping up to 2.5 m (8 ft 2 in) from a standing start when startled (up to 3 m (9.8 ft) for young elands). The common eland's life expectancy is generally between 15 and 20 years; in captivity, some live up to 25 years.Eland herds are accompanied by a loud clicking sound that has been subject to considerable speculation. The weight of the animal may cause the two halves of its hooves to splay apart, and the clicking is the result of the hoof snapping together when the animal raises its leg. The sound carries some distance from a herd, and may be a form of communication.
+
+
+== Taxonomy ==
+The common eland was first described in 1766 by German zoologist and botanist Peter Simon Pallas. It belongs to the order Artiodactyla, family Bovidae, and subfamily Bovinae. Common elands are sometimes considered part of the genus Tragelaphus on the basis of molecular phylogenetics, but are usually categorized as Taurotragus, along with the giant eland (T. derbianus).
+
+
+=== Subspecies ===
+Three subspecies of common elands have been recognized, though their validity has been disputed.
+T. o. oryx (Pallas, 1766; Cape eland): also called alces, barbatus, canna and oreas. It is found in Southern and southwestern Africa. The fur is tawny and adults lose their stripes.
+T. o. livingstonii (Sclater, 1864; Livingstone's eland): also called kaufmanni, niediecki, selousi and triangularis. It is found in the Central Zambezian miombo woodlands. Livingstone's eland has brown fur with up to 12 stripes.
+T. o. pattersonianus (Lydekker, 1906; East African eland or Patterson's eland): also called billingae. It is found in East Africa, hence its common name. Like Livingstone's eland, its fur can also have up to 12 stripes.
+		
+		
+
+
+== Genetics and evolution ==
+Male elands have 31 diploid chromosomes and females have 32. The male (Y) chromosome has been translocated to the short arm of an autosome. Both the X chromosome and Y chromosome replicate late; they do not match well and are variable. The chromosomes resemble those of the greater kudu (Tragelaphus strepsiceros).Male elands and female greater kudus can produce a viable male hybrid, though whether it is sterile is unknown. An accidental crossing of an East African common eland (T. o. pattersonianus') with an East African kudu (T. s. bea) occurred in the San Diego Zoo Safari Park. This was believed to be due to the absence of male kudus in the herd. The hybrid produced was sterile, which was unexpected before the study. The study confirmed the chromosome numbers of both the eland and the kudu and the strangeness of their attached Y chromosomes. Reports state that repeated matings of male elands with domestic (Bos primigenius) and zebu cows (Bos indicus) have also produced sterile hybrids. Female elands can also act as surrogates for bongos.The Bovidae family ancestors of the common eland evolved approximately 20 million years ago in Africa; fossils are found throughout Africa and France, but the best record appears in sub-Saharan Africa. The first members of the tribe Tragelaphini appear six million years in the past during the late Miocene. An extinct ancestor of the common eland (Taurotragus arkelli) appears in the Pleistocene in northern Tanzania and the first T. oryx fossil appears in the Holocene in Algeria.In 2010, a genetic study was made basing on the evolutionary history of common elands. Located in the sub-Saharan savanna biome of East and Southern Africa, the study used methods including analysis of mitochondrial DNA control-region fragments from 122 individuals to learn more about various topics, such as the phylogeography, genetic diversity, and demographic history of the species. The conclusions strongly supported the presence of a longer-standing population in the south and a mosaic of Pleistocene refugia in the east. Today, their extinction from these parts is thought to be due to colonization. The similarity of dates obtained from more studies indicates a significant event around 200 ka, which had brought a great change in the genetic history of the species.
+
+
+== Habitat and distribution ==
+
+Common elands live on the open plains of Southern Africa and along the foothills of the great southern African plateau. The species extends north into Ethiopia and most arid zones of South Sudan, west into eastern Angola and Namibia, and south to South Africa. However, a low density of elands exists in Africa due to poaching and human settlement.
+Elands prefer to live in semiarid areas that contain many shrub-like bushes, and often inhabit grasslands, woodlands, subdesert, bush, and mountaintops with altitudes of about 15,000 ft (4,600 m). Elands do, however, avoid forests, swamps and deserts. The places inhabited by elands generally contain Acacia, Combretum, Commiphora, Diospyros, Grewia, Rhus, and Ziziphus trees and shrubs; some of these also serve as their food.
+Eland can be found in many national parks and reserves today, including Nairobi National Park and Tsavo East National Park, Tsavo West National Park, Masai Mara National Reserve, (Kenya); Serengeti National Park, Ruaha National Park and Tarangire National Park, Ngorongoro Crater, (Tanzania); Kagera National Park (Rwanda); Nyika National Park (Malawi); Lake Mburo National Park (Uganda); Kidepo Valley National Park (Uganda); Luangwa Valley and Kafue National Park (Zambia); Hwange National Park, Matobo National Park, Tuli Safari Area and Chimanimani Eland Sanctuary (Zimbabwe); Kruger National Park, Kgalagadi Transfrontier Park, Giant's Castle and Suikerbosrand NR (South Africa).They live on home ranges that can be 200–400 km2 for females and juveniles and 50 km2 for males.
+
+
+== Ecology and behavior ==
+
+Common elands are nomadic and crepuscular. They eat in the morning and evening, rest in shade when hot, and remain in sunlight when cold. They are commonly found in herds numbering up to 500, with individual members remaining in the herd from several hours to several months. Juveniles and mothers tend to form larger herds, while males may separate into smaller groups or wander individually. During estrus, mainly in the rainy season, groups tend to form more regularly. In Southern Africa, common elands will often associate with herds of zebras, roan antelopes and oryxes.Common elands communicate via gestures, vocalizations, scent cues, and display behaviors. The flehmen response also occurs, primarily in males in response to contact with female urine or genitals. Females urinate to indicate fertility during the appropriate phase of their estrous cycle, as well as to indicate their lack of fertility when harassed by males. If eland bulls find any of their predators nearby, they bark and attempt to attract the attention of others by trotting back and forth until the entire herd is conscious of the danger. Some of their main predators include lions, African wild dogs, cheetahs, and spotted hyenas. Juvenile elands are more vulnerable than adults to their predators.
+
+
+=== Diet ===
+
+Common elands are herbivores that browse during drier winter, but have also adapted to grazing during the rainy season when grasses are more common and nutritious. They require a high-protein diet of succulent leaves from flowering plants, but will consume lower-quality plant material if available, including forbs, trees, shrubs, grasses, seeds, and tubers. Grasses that elands eat include Setaria and Themeda and fruits from Securinega and Strychnos. Large antelope can survive on lower-quality food in times of little rain. 
+Most of their water is obtained from their food, though they drink water when available. As they quickly adjust to the surroundings due to seasonal changes and other causes, they change their feeding habits. They also use their horns to break off branches that are hard to reach.
+
+
+=== Thermoregulation ===
+Common elands have several thermoregulatory adaptations to help them withstand the extreme temperatures of their environments. Using peripheral thermal receptors on the skin, elands can sense heat and increase or decrease evaporative cooling accordingly. On sunnier days, common elands maintain a cooler skin temperature relative to their inner body temperature. Elands achieve cooler skin temperatures by increasing cutaneous evaporation. This allows them to feel cooler, even though their internal body temperature stays relatively the same throughout the day. The eland can also conserve water by increasing its body temperature. When temperatures rise above a certain threshold, an increase in sweating and panting is also observed. Common elands use their sparse fur coats to dissipate excess heat via reradiation. The dewlap is also believed to play a role in thermoregulation. Due to its high surface area to volume ratio, it may allow for efficient thermoregulation in larger common elands with larger dewlaps.

+=== Sociability and reproduction ===
+
+Females are sexually mature at 15 to 36 months and males at 4 to 5 years. Mating may occur anytime after reaching sexual maturity, but is mostly seen in the rainy season. In Zambia, young are born in July and August, while elsewhere this is the mating season. Mating begins when elands gather to feed on lush, green plains with plentiful grass, and some males and females start mating with each other in separate pairs. Males chase the females to find out if they are in estrus. They also test the female's urine. Usually, a female chooses the most dominant and fit male to mate with. Sometimes, she runs away from males trying to mate, causing more attraction. This results in fights between males, in which their hard horns are used. A female allows a male to mount after two to four hours. Males usually keep close contact with females in the mating period. The dominant male can mate with more than one female. Females have a gestation period of nine months, and give birth to only one calf each time.Males, females, and juveniles each form separate social groups. The male groups are the smallest; the members stay together and search for food or water sources. The female group is much larger and covers greater areas. They travel the grassy plains in wet periods and prefer bushy areas in dry periods. Females have a complex linear hierarchy. The nursery and juvenile group is naturally formed when females give birth to calves. After about 24 hours of the delivery, the mother and calf join this group. The calves start befriending each other and stay back in the nursery group, while the mother returns to the female group. The calves leave the nursery group when they are at least two years old and join a male or female group.
+
+
+=== Diseases and parasites ===
+Common elands are resistant to trypanosomiasis, a protozoan infection that has the tsetse fly as a vector, but not to the Rhipicephalus-transmitted disease theileriosis. The disease-causing bacterium Theileria taurotragi has caused many eland deaths. Clostridium chauvoei, another bacterium, can be harmful, as well. Elands are also hosts to several kinds of ticks. In one study, an eland was found to be host to the Amblyomma species A. gemma and A. variegatum, and Rhipicephalus species R. decoloratus, R. appendiculatus, R. evertsi, R. pulchellus and R. pravus. Elands produce antibodies for Brucella bacteria, but none for Mycobacterium paratuberculosis or various types of pneumonia like contagious bovine pneumonia and contagious caprine pneumonia, normally infectious in cows or antelopes.
+
+
+== Interaction with humans ==
+
+
+=== Conservation ===
+
+Currently, common elands are not endangered. They are conserved by the United States Endangered Species Act, and regulated in international trade by the Convention on International Trade in Endangered Species. Using ground counts and aerial surveys, the International Union for Conservation of Nature (IUCN) calculates the population density of the common eland to be between 0.05 and 1 per square kilometre with a total population estimate of 136,000. Populations are considered stable or increasing in the countries of Namibia, Botswana, Zimbabwe, South Africa, Malawi, and possibly Tanzania.
+The population is, however, gradually decreasing due to habitat loss, caused by expanding human settlements and poaching for its superior meat. As they are docile and inactive most of the time, they can easily be killed. The species became extinct in Eswatini and Zimbabwe, but has been reintroduced.
+The IUCN states that about half of the estimated total population lives in protected areas and 30% on private land. Protected areas that support major populations include Omo (Ethiopia), Serengeti, Katavi, Ruaha, and Selous-Kilombero (Tanzania), Kafue and North Luangwa (Zambia), Nyika (Malawi), Etosha (Namibia), Kgalagadi Transfrontier Park (Botswana/South Africa) and Ukhahlamba Drakensberg Park (South Africa). Most of these populations appear to be stable. Relatively large numbers of common elands now live on private land, particularly in Namibia, Zimbabwe, and South Africa, reflecting its value as a trophy animal. Common elands have also been widely domesticated in Zimbabwe, South Africa, and Kenya, as well as in Russia and Ukraine.
+
+
+=== Uses ===
+
+The common eland is sometimes farmed and hunted for its meat, and in some cases can be better used than cattle because it is more suited to African climates. This has led to some Southern African farmers switching from cattle to eland. Common elands are also pictured as supporters in the coat of arms of Grootfontein, Namibia.
+
+
+=== Husbandry ===
+Common elands have a mild temperament and have been successfully domesticated for meat and milk production in South Africa and Russia. Their need for water is quite low because they produce urine with a highurea content, but they require a substantial grazing area, along with salt licks and large amounts of supplementary feed such as maize, sorghum, melons, and beans, which can be expensive. A female can produce up to 7 kg (15 lb) of milk per day that is richer in milkfat than cow milk. The pleasant-tasting milk has a butterfat content of 11-17% and can be stored for up to eight months if properly prepared, versus several days for cow milk.Housing common elands is difficult due to their ability to jump over fences as high as 3 m (9.8 ft) or simply break through using their substantial mass. Sometimes, wild elands break through enclosures to mix with domesticated ones. Common elands can reproduce in captivity, but calf survival is low and the young may need to be separated from their mothers to ensure health and adequate feeding. Husbandry requires care because the generally placid animals startle easily and require large amounts of space.

+The sitatunga or marshbuck (Tragelaphus spekii) is a swamp-dwelling antelope found throughout central Africa, centering on the Democratic Republic of the Congo, the Republic of the Congo, Cameroon, parts of Southern Sudan, Equatorial Guinea, Burundi, Ghana, Botswana, Rwanda, Zambia, Gabon, the Central African Republic, Tanzania, Uganda and Kenya.
+The sitatunga is confined to swampy and marshy habitats. Here they occur in tall and dense vegetation as well as seasonal swamps, marshy clearings in forests, riparian thickets and mangrove swamps.
+
+
+== Taxonomy and genetics ==
+The scientific name of the sitatunga is Tragelaphus spekii. The species was first described by the English explorer John Hanning Speke in 1863. Speke first observed the sitatunga at a lake named "Little Windermere" (now Lake Lwelo, located in Kagera, Tanzania). In his book Journal of the Discovery of the Source of the Nile, Speke called the animal "nzoé" (Kiswahili name for the animal) or "water-boc" (due to its resemblance to the waterbuck). The scientific name has often been misstated as T. spekei, and either Speke or Sclater is referred to as the binomial authority. 
+Speke had stated in a footnote in his book that the species had been named Tragelaphus spekii by English zoologist Philip Sclater. However, according to the International Code of Zoological Nomenclature (Article 50.1.1) and the International Commission on Zoological Nomenclature, that acknowledge the person who first described the species, simply declaring Sclater as the authority in a footnote is insufficient to recognise him as the author. Hence, Speke was recognised as the correct authority and T. spekii (where spekii is the genitive of the Latinised "Spekius") was considered the correct name for the species.The sitatunga is placed under the genus Tragelaphus and in the family Bovidae. In 2005, Sandi Willows-Munro of the University of KwaZulu-Natal (Durban) carried out a mitochondrial analysis of the nine Tragelaphus species. mtDNA and nDNA data were compared. The results showed that sitatunga plus bongo (T. eurycerus) form a monophyletic clade with the mountain nyala (T. buxtoni) and bushbuck (T. scriptus). The greater kudu (T. strepsiceros) split from this clade approximately 8.6 million years ago.Within Tragelaphus, the bushbuck, bongo, sitatunga and nyala (T. angasii) are particularly close relatives. The bushbuck and sitatunga are genetically similar enough to hybridise. Hybrids between bongo and sitatunga have proved to be fertile. The sitatunga is more variable in its general characters than any other member of the tribe Strepsicerotini, that consists of the genera Taurotragus (elands) and Tragelaphus, probably because of their confinement to swampy and marshy habitats.On the basis of physical characteristics such as hair texture, coat colour and the coat stripes, up to ten subspecies of the sitatunga have been described. However, these factors may not be reliable since hair texture could vary with the climate, while pelage colour and markings vary greatly among individuals. Moreover, the coat might darken and the stripes and spots on it might fade with age, especially in males. The species might even be monotypic, however, based on different drainage systems, three distinct subspecies are currently recognised:
+T. s. spekii (Speke, 1863): Nile sitatunga or East African sitatunga. Found in the Nile watershed.
+T. s. gratus (Sclater, 1880): Congo sitatunga or forest sitatunga. Found in western and central Africa.
+T. s. selousi (W. Rothschild, 1898): Southern sitatunga or Zambezi sitatunga. Found in southern Africa.
+
+
+== Description ==
+
+The sitatunga is a medium-sized antelope. It is sexually dimorphic, with males considerably larger than females. The head-and-body length is typically between 136–177 cm (54–70 in) in males and 104–146 cm (41–57 in) in females. Males reach approximately 81–116 cm (32–46 in) at the shoulder, while females reach 72–90 cm (28–35 in). Males typically weigh 76–119 kg (168–262 lb), while females weigh 24–57 kg (53–126 lb). The tail is 14–37 cm (5.5–14.6 in) long. The saucer-shaped ears are 11–17 cm (4.3–6.7 in) long. Only the males possess horns; these are spiral in shape, have one or two twists and are 45–92 cm (18–36 in) long. The sitatunga is almost indistinguishable from the nyala, except in pelage and spoor. Speke pointed out that, though "closely allied" to the waterbuck, the sitatunga lacks stripes and is spotted instead.The coat colour varies geographically, but, in general, is a rufous red in juveniles and chestnut in females. There are white facial markings, as well as several stripes and spots all over, though they are only faintly visible. White patches can be seen on the throat, near the head and the chest. A pair of inguinal scent glands are present. The coats of males darken with age, becoming gray to dark brown. Males develop a rough and scraggy mane, usually brown in colour, and a white dorsal stripe. There is a chevron between the eyes of the males.The body and legs of this antelope are specially adapted to its swampy habitat. The hooves of the male are elongated and widely splayed. The rubbery, shaggy, water-repellent coat is minimally affected by slimy and muddy vegetation. The wedge-like shape and lowering of the head, coupled with the backward bend of the horns (in males) provides for easy navigation through dense vegetation. The pasterns are flexible, and the hooves, banana-like in shape, can reach a length of up to 16 cm (6.3 in) in the hindlegs and 18 cm (7.1 in) in the forelegs. The pointed toes allow it to walk slowly and almost noiselessly through the water. Moreover, the colour of the coat provides an excellent camouflage. Hearing is acute, and the ears are so structured that the animal can accurately determine the direction from where a sound has originated. This adaptation is of profound use in habitats where long sight is of very little value due to the density and darkness of the environment.
+
+
+== Ecology and behaviour ==
+
+Sitatunga are active mainly during the early hours after dawn, the last one or two hours before dusk, and at night, and spend a large part of this time feeding. Basically sedentary, they rest in flat areas and reed beds, especially during the hotter part of the day. They seldom leave their swamp habitat during the daytime. Though sitatunga commonly form pairs or remain solitary, larger groups have also been observed. A study in Kenya recorded a herd of as many as nine individuals, comprising an adult male, four females and four juveniles. Loose groups may be formed but interaction among individuals is very low. Individuals generally associate only with their own sex.The sitatunga is not territorial. Males may engage in locking horns with other males and attacking vegetation using their horns. They may perform feinting by raising their forelegs with the hindlegs rooted in the ground as a threat display. Sitatunga interact with each other by first touching their noses, which may be followed by licking each other and nibbling. Alarmed animals may stand motionless, with the head held high and one leg raised. Sitatunga may occasionally emit a series of coughs or barks, usually at night, which may cause other animals to join in, and these sounds can be heard across the swamp. This barking may be used by females to warn off other females. Males often utter a low bellow on coming across a female or a herd of females in the mating season. A low-pitched squeak may be uttered while feeding. Mothers communicate with their calves by bleats.Sitatunga can feed or rest close to southern lechwe herds, but do not interact with them. They often attract yellow-billed oxpeckers, African jacanas and great egrets. Sitatunga are good swimmers, but limit themselves to water with profuse vegetation in order to escape crocodiles. In some cases, for instance when troubled by flies or pursued by predators, the sitatunga might fully submerge themselves in the water except for the nose and the eyes, which they keep slightly above the water surface. Due to its close association with water, the sitatunga are often described as "aquatic antelopes", like the waterbuck. They often dry themselves under the sun after feeding in water. Predators of the sitatunga include lions, wild dogs, crocodiles and leopards.
+
+
+=== Diet ===
+Sitatunga are selective and mixed feeders. They feed mainly on new foliage, fresh grasses, sedges and browse. Preferred plants include: bullrushes (Typha), sedges (Cyperus), aquatic grasses (Vossia, Echinochloa, Pennisetum, Leersia, Acroceras and Panicum. Species in Umbelliferae and Acanthaceae are preferred in Saiwa Swamp National Park (Kenya), and Fabaceae species are preferred in Bangweulu and Busanga (in Kafue National Park). They feed mostly in the wetland fringes. Diet preferences may vary seasonally in swamps where water levels change notably. Like the gerenuk, the sitatunga may stand on its hindlegs to reach higher branches of trees, or even use its horns to pull down the branches.A study recorded forty major species eaten by the animal, the majority of which were herbs. Sweet potato was the most preferred crop. The study predicted an increase in preference for crops due to seasonal food variations. Another study showed that annual floods affect the seasonal movement and diet of the species. These floods force the animals out of the reed beds onto the flooded grasslands when the water levels are high. At low water levels the cattle take over the flooded plains and send the sitatunga back to their original place.
+
+
+=== Reproduction ===
+
+Females are sexually mature by one year of age, while males take one-and-a-half-year before they mature. Breeding occurs throughout the year. When females gather, the males compete among each other for the right to mate, showing polygyny in males. The rutting male approaches the female in a lower bending posture, sniffing her vulva. The female may move slowly or react nervously. Even if the female flees, the male continues pursuing her steadily, without showing any sign of hurry. A receptive female will raise her head with her mouth wide open, following which the male will begin attempts at mounting. At the time of mounting the female lowers her head, while the male first bends and then straightens his forelegs and rests his head and neck on her back. The two remain together for one or two days, during which time the male ensures that no other male can approach the female.Gestation lasts for nearly eight months, after which generally a single calf is born. Parturition occurs throughout the year, though a peak may occur in the dry season. Calves are hidden adroitly, and brought out of cover only in the presence of many other sitatunga. The mother gazes and nods at the calf to summon it for nursing. A calf follows its mother about even after she has given birth to another calf. The mother suckles and licks her calf for about six months. The calf takes time to master the specialised gait of the sitatunga, and thus often loses its balance and falls in water. Males, and even some females, have been observed to leave their herds even before reaching sexual maturity due to intrasexual competition. Lifespan recorded in captivity averages 22 to 23 years.
+
+
+== Habitat and distribution ==
+The sitatunga is an amphibious antelope (meaning it can live on both land and water) confined to swampy and marshy habitats. They occur in tall and dense vegetation of perennial as well as seasonal swamps, marshy clearings in forests, riparian thickets and mangrove swamps. Sitatunga move along clearly marked tracks in their swampy habitat, often leading to reed beds. These tracks, up to 7 m (23 ft) wide, can lead to feeding grounds and nearby riverine forests. The sitatunga hold small home ranges near water bodies  In savannas, they are typically found in stands of papyrus and reeds (Phragmites species and Echinochloa pyramidalis). They share their habitat with the Nile lechwe in the Sudd swamps and with the southern lechwe in Angola, Botswana and Zambia.The sitatunga is native to Angola, Benin, Botswana, Burundi, Cameroon, Central African Republic, Chad, The Democratic Republic of the Congo, Equatorial Guinea, Gabon, Gambia, Ghana, Guinea, Guinea-Bissau, Kenya, Mozambique, Namibia, Nigeria, Rwanda, Senegal, South Sudan, Tanzania, Uganda, Zambia and Zimbabwe. It is extinct in Niger, where it formerly occurred in the Lake Chad region, and is feared to be extinct in Togo, where its habitat has been taken over by dense human settlements. While it is localised and sporadic in western Africa, the sitatunga is still common in the forests of central Africa and certain swampy regions in central, eastern and southern Africa.
+
+
+== Threats and conservation ==
+Habitat loss is the most severe threat to the survival of the sitatunga. Other threats include the increasing loss of wetlands, that has isolated populations; and long-term changes in the water level, that affects the nearby vegetation and thus bears upon their diet. Vast areas of Bangweulu and Busanga are burnt every year, placing animals like the sitatunga at grave risk given the inflammability of swamps. The sitatunga has been classified under the Least Concern category by the International Union for Conservation of Nature and Natural Resources (IUCN), and under Appendix III (Ghana) of the Washington Convention (CITES).In Senegal, intensive hunting for meat and habitat degradation have made the sitatunga very rare. Formerly it was common throughout Gambia, but now it is confined to a few inaccessible swamps; a population has been introduced in the Abuko Nature Reserve. On the other hand, though the animal is hunted by locals primarily for food, Botswana still supports a large portion of the total population. The species is of great economic significance for northern Botswana, that produces some of the world's biggest sitatunga trophies. Its status is unclear in Chad, Ghana, Guinea, Burundi and Mozambique and Zimbabwe. Significant populations still exist in countries such as Cameroon, Central African Republic, The Democratic Republic of Congo, Equatorial Guinea, Gabon, Tanzania and Zambia. The inaccessibility of its habitat has rendered population estimates very difficult. In 1999, Rod East of the IUCN SSC Antelope Specialist Group estimated a total population of 170,000, but this is likely to be an overestimate. Its numbers are decreasing in areas of heavy human settlement, but are stable elsewhere.Around 40 percent of the populations (based on the overestimate of 170,000) occurs in protected areas, mainly in Okavango Delta and Linyanti and Chobe swamps (Botswana); Dja Faunal Reserve and Lobéké National Park (Cameroon); Bangassou (Central African Republic); Odzala National Park, Lake Télé Community Reserve, Likouala and Salonga National Park (The Democratic Republic of Congo); Monte Alén National Park (Equatorial Guinea); Saiwa Swamp National Park (Kenya); Akagera National Park (Rwanda); Moyowosi and Kigosi Game Reserves (Tanzania); Bangweulu and Busanga Swamps (Zambia). However, only a few are of these parks and reserves are well-protected and managed.

+The common bottlenose dolphin or Atlantic bottlenose dolphin (Tursiops truncatus) is a wide-ranging marine mammal of the family Delphinidae. The common bottlenose dolphin is a very familiar dolphin due to the wide exposure it gets in captivity in marine parks and dolphinariums, and in movies and television programs. It is the largest species of the beaked dolphins. It inhabits temperate and tropical oceans throughout the world, and is absent only from polar waters. While formerly known simply as the bottlenose dolphin, this term is now applied to the genus Tursiops as a whole. As considerable genetic variation has been described within this species, even between neighboring populations, many experts think additional species may be recognized.
+
+
+== Taxonomy ==
+Until 1998, all bottlenose dolphins were considered one species T. truncatus. That year, the Indo-Pacific bottlenose dolphin (T. aduncus) was recognized as a separate species. The two species are thought to have split during the mid-Pleistocene, about 1 million years ago.Currently, three common bottlenose dolphin subspecies are recognized:
+T. t. truncatus, the nominate subspecies
+T. t. ponticus, or the Black Sea bottlenose dolphin
+T. t. gephyreus, or Lahille’s bottlenose dolphinBottlenose dolphins along the southern California and Baja California coasts were previously recognized as the Pacific bottlenose dolphin, T. t. gillii. The name has since been reclassified as a junior synonym of Tursiops truncatus.A 2020 study identified four distinct lineages within T. truncatus, each of which could be a distinct subspecies: a lineage native to the coastal regions of the western North Atlantic (off the coast of North America), an offshore lineage found worldwide in pelagic ecosystems, a lineage native to the Mediterranean, and a lineage restricted to the Black Sea (previously described as T. truncatus ponticus). The study noted only weak differentiation between the Black Sea and Mediterranean lineages, and found them to form a sister group to the offshore lineage, indicating that they likely descended from offshore bottlenoses that colonized the Mediterranean and Black Seas. The clade containing the offshore, Mediterranean, and Black Sea populations was sister to the western North Atlantic lineage, indicating deep divergence between the two.
+
+
+== Description ==
+Common bottlenose dolphins are grey, and between 2 and 4 m (6.6 and 13.1 ft) long, and weigh between 150 and 650 kg (330 and 1,430 lb). Males are generally larger and heavier than females. In most parts of the world, adult length is between 2.5 and 3.5 m (8.2 and 11.5 ft); weight ranges between 200 and 500 kg (440 and 1,100 lb). Dolphins have a short and well-defined snout that looks like an old-fashioned gin bottle, which is the source for their common name.
+
+Like all whales and dolphins, though, the snout is not a true nose; the nose instead evolved into the blowhole on the top of their heads. Their necks are more flexible than other dolphins' due to five of their seven vertebrae not being fused together like in other dolphins.
+
+
+=== Intelligence ===
+
+The common bottlenose dolphin has a larger brain than humans. Many investigations of bottlenose intelligence include tests of mimicry, use of artificial language, object categorization, and self-recognition. This intelligence has driven considerable interaction with humans. The common bottlenose dolphin is popular in aquarium shows and television programs such as Flipper. It has also been trained for military uses such as locating sea mines or detecting and marking enemy divers, as for example in the U.S. Navy Marine Mammal Program. In some areas, they cooperate with local fishermen by driving fish toward the fishermen and eating the fish that escape the fishermen's nets.
+
+
+== Ecology and behavior ==
+
+As a very social species, the common bottlenose dolphin lives in groups called pods that typically number about 15 individuals, but group size varies from pairs of dolphins to over 100 or even occasionally over 1,000 animals for short periods of time. The types of groups include: nursery groups, juvenile groups, and groups of adult males.
+
+
+=== Diet ===
+Its diet consists mainly of eels, squid, shrimp and a wide variety of fishes. It does not chew its food, instead swallowing it whole. Dolphin pods often work as a team to harvest schools of fish, though they also hunt individually. Dolphins search for prey primarily using echolocation, which is a form of sonar.
+The diet of common bottlenose dolphin pods varies depending on area. Along the U.S. Atlantic coast, the main prey includes Atlantic croakers (Micropogonias undulatus), spot (Leiostomus xanthurus) and American silver perch (Bairdiella chrysoura), while in South Africa, African massbankers (Trachurus delagoa), olive grunters (Pomadasys olivaceus), and pandora (Pagellus bellottii) are common bottlenose dolphin's typical prey.According to combined stomach content and stable isotope analyses in the Gulf of Cádiz, although European conger (Conger conger) and European hake (Merluccius merluccius) are most important prey of common bottlenose dolphins, mass-balance isotopic mixing model (MixSIAR), using δ13C and δ15N showns that Sparidae species; seabreams (Diplodus annularis and D. bellottii), rubberlip grunt (Plectorhinchus mediterraneus), and common pandora, (Pagellus erythrinus)) and a mixture of other species including European hake, mackerels (Scomber colias, S. japonicus and S. scombrus), European conger, red bandfish (Cepola macrophthalma) and European pilchard (Sardina pilchardus) are the assimilated diet.Research indicates that the type and range of fish in a dolphin's diet can have a significant impact on its health and metabolism.
+
+
+=== Communication ===
+Dolphins also use sound for communication, including squeaks emitted from the blowhole, whistles emitted from nasal sacs below the blowhole, and sounds emitted through body language, such as leaping from the water and slapping their tails on the water. The dolphins address each other individually through matched whistling, where individuals respond to whistles of other dolphins by using the same whistle.Their heads contain an oily substance that both acts as an acoustic lens and protects the brain case. They emit clicking sounds and listen for the return echoes to determine the location and shape of nearby items, including potential prey.
+
+
+=== Reproduction ===
+
+Mating behavior of bottlenose dolphin is polygamous. Although they can breed throughout the year, it mostly occurs in spring. Males form alliances to seek an estrous female. For a chance to mate with the female, males separate the female from her home range. Females bear a calf every three to six years. After a year-long gestation period, females bear a single calf. Newborn calves are between 0.8 and 1.4 m (2 ft 7 in and 4 ft 7 in) long and weigh between 15 and 30 kg (33 and 66 lb). They can live as long as 40–50 years. The calf suckling lasts between 18 and 20 months. Sexual maturity varies by population, and ranges from 5–14 years of age; sexual maturity occurs between 8 and 13 years for males and 5 to 10 years for females.
+
+
+=== Life expectancy ===
+The average life expectancy of common bottlenose dolphins is about 17 years old, but in captivity they have been known to live to up to 51 years old.
+
+
+== Distribution ==
+The common bottlenose dolphin can be found in temperate, subtropical, and tropical oceans around the world. The global population has been estimated at 600,000. Some bottlenose populations live closer to the shore (inshore populations) and others live further out to sea (offshore populations). Generally, offshore populations are larger, darker, and have proportionally shorter fins and beaks. Offshore populations can migrate up to 4,200 km (2,600 mi) in a season, but inshore populations tend to move less. However, some inshore populations make long migrations in response to El Niño events. The species has occurred as far as 50° north in eastern Pacific waters, possibly as a result of warm water events. The coastal dolphins appear to adapt to warm, shallow waters. It has a smaller body and larger flippers, for maneuverability and heat dispersal. They can be found in harbors, bays, lagoons and estuaries. Offshore dolphins, however, are adapted to cooler, deeper waters. Certain qualities in their blood suggest they are more suited to deep diving. Their considerably larger body protects them against predators and helps them retain heat.
+
+
+== Other human interactions ==
+
+Some interactions with humans are harmful to the dolphins. Dolphin hunting industry exists in multiple countries including Japan, where common bottlenose dolphins are hunted for food annually in the town of Taiji, and the Faroe Islands. Also, dolphins are sometimes killed inadvertently as a bycatch of tuna fishing.Tião was a well-known solitary male bottlenose dolphin that was first spotted in the town of São Sebastião in Brazil around 1994 and frequently allowed humans to interact with him. The dolphin later became infamous for killing a swimmer and injuring many others, which earned it the nickname of killer dolphin.
+Fungie is another solitary male bottlenose, living in close contact with humans in Dingle Harbour, Ireland, since 1983. He has become a symbol of the town, although some doubt exists over whether he is a single dolphin.
+
+
+== Conservation ==
+The North Sea, Baltic, Mediterranean and Black Sea populations of the common bottlenose dolphin are listed in Appendix II to the Convention on the Conservation of Migratory Species of Wild Animals (CMS) of the Bonn Convention, since they have an unfavorable conservation status or would benefit significantly from international cooperation organized by tailored agreements.The species is included in Appendix II of the Convention on International Trade in Endangered Species (CITES), meaning international trade (including in parts/derivatives) is regulated.Estimated population of a few specific areas are including:
+The species is covered by the Agreement on Small Cetaceans of the Baltic, North East Atlantic, Irish and North Seas (ASCOBANS), the Agreement on the Conservation of Cetaceans in the Black Sea, Mediterranean Sea and Contiguous Atlantic Area (ACCOBAMS), the Memorandum of Understanding for the Conservation of Cetaceans and Their Habitats in the Pacific Islands Region, and the Memorandum of Understanding Concerning the Conservation of the Manatee and Small Cetaceans of Western Africa and Macaronesia.
+
+
+=== Marine pollution ===
+
+Common bottlenose dolphins are the most common apex predators found in coastal and estuarine ecosystems along the southern coast of the US, thus serve as an important indicator species of bioaccumulation and health of the ecosystem.
+It is believed that some diseases commonly found in dolphins are related to human behaviors, such as water pollution. Water pollution is linked to point and non-point source pollution. Point source pollution comes from a single source such as an oil spill and/or chemical discharge from a specific facility. The environmental impact of the Deepwater Horizon oil spill caused a direct impact and still serves as a long-term impact of future populations. Common bottlenose dolphins use these important habitats for calving, foraging, and feeding. Environmental impacts or changes from chemicals or marine pollution can alter and disrupt endocrine systems, affecting future populations. For example, oil spills have been related to lung and reproductive diseases in female dolphins. A recent studysuggested signs of lung disease and impaired stress in 32 dolphins that were captured and assessed in Barataria Bay, Louisiana, US. Out of these 32 dolphins, 10 were found pregnant and, upon a 47-month check up, only 20% produced feasible calves, compared to a previous success rate of 83%, in the same area. It is believed that a recent oil spill in this area is partially to blame for these severely low numbers.
+Dense human development along the eastern coast of Florida and intense agricultural activity have resulted in increased freshwater inputs, changes in drainage patterns, and altered water quality (i.e. chemical contamination, high nutrient input, decreased salinity, decreased sea grass habitat, and eutrophication. High nutrient input from agriculture chemicals and fertilizers causes eutrophication and hypoxia, causing a severe reduction in water quality. Excess of phosphorus and nitrogen from these non-point sources deplete the natural cycle of oxygen by overconsumption of algae. Harmful algal blooms are responsible for dead zones and unusual mortality events of common bottlenose dolphins consuming these toxic fish from the brevetoxin produced by the dinoflagellate Karenia brevis. Brevetoxins are neurotoxins that can cause acute respiratory and neurological symptoms, including death, in marine mammals, sea turtles, birds, and fishes.

+The Eurasian brown bear (Ursus arctos arctos) is one of the most common subspecies of the brown bear, and is found in much of Eurasia. It is also called the European brown bear, common brown bear, common bear, and colloquially by many other names. The genetic diversity of present-day brown bears (Ursus arctos) has been extensively studied over the years and appears to be geographically structured into five main clades based upon analysis of the mtDNA.
+
+
+== Description ==
+The Eurasian brown bear has brown fur, which ranges from yellowish-brown to dark brown, red-brown, and almost black in some cases; albinism has also been recorded. The fur is dense to varying degrees and the hair can grow up to 10 cm (3.9 in) in length. The head normally is quite round in shape and has relatively small rounded ears, a wide skull and a mouth equipped with 42 teeth, including predatory teeth. It has a powerful bone structure and large paws equipped with claws that can grow up to 10 cm (3.9 in) in length. The weight varies depending on habitat and the time of the year. A full-grown male weighs on average between 250 and 300 kilograms (550 and 660 lb), and reaches a maximum weight of 481 kg (1,060 lb) and length of nearly 2.5 m (8.2 ft). Females typically range between 150 and 250 kg (550 lb). They have a lifespan of 20 to 30 years in the wild.
+
+
+== History ==
+Brown bears were present in Britain until no later than AD 1000, when they had been exterminated through over-hunting.Eurasian brown bears were used in Ancient Rome for fighting in arenas. The strongest bears apparently came from Caledonia and Dalmatia.In antiquity, the Eurasian brown bear was largely carnivorous, with 80% of its diet consisting of animal matter. However, as its habitat increasingly diminished, the portion of meat in its diet decreased with it until by the late Middle Ages, meat consisted of only 40% of its dietary intake. Today, meat makes up little more than 10–15% of its diet. Whenever possible, the brown bear will consume sheep.Unlike in North America, where an average of two people a year are killed by bears, Scandinavia only has records of three fatal bear attacks within the last century. However, in late 2019, brown bears killed three men in Romania in just over a month.
+
+
+== Species origin ==
+The oldest fossils are from the Choukoutien, China, and date back about 500,000 years. It is known from mtDNA studies that during the Pleistocene ice age it was too cold for the brown bear to survive in Europe except in three places: Russia, Spain, and the Balkans.Modern research has made it possible to track the origin of the subspecies. The species to which it belongs developed more than 500,000 years ago, and researchers have found that the Eurasian brown bear separated about 850,000 years ago, with one branch based in Western Europe and the other branch in Russia, Eastern Europe and Asia. Through research of mitochondrial DNA (mtDNA), researchers have found that the European family has divided into two clades—one in the Iberian Peninsula and the Balkans, the other in Russia.There is a population in Scandinavia that includes bears of the western and eastern lineages. By analyzing the mtDNA of the southern population, researchers have found that they have probably come from populations in the Pyrenees in Southern France and Spain and the Cantabrian Mountains (Spain). Bears from these populations spread to southern Scandinavia after the last ice age. The northern bear populations originate in the Finnish/Russian population. Probably their ancestors survived the ice age in the ice-free areas west of the Ural Mountains, and thereafter spread to Northern Europe.
+
+
+== Distribution ==
+Brown bears could once be found across most of Eurasia, compared to the more limited range today.
+Although included as of Least Concern on the 2006 IUCN Red List of Threatened Species (which refers to the global species, not to the Eurasian brown bear specifically), local populations are becoming increasingly scarce. As the IUCN itself adds: "Least Concern does not always mean that species are not at risk. There are declining species that are evaluated as Least Concern."
+The brown bear has long been extinct in Ireland, Britain, Denmark, the Netherlands and Belgium, but still exists in Northern Europe and in Russia.
+Globally, the largest population is found east of the Ural mountain range, in the large Siberian forests; brown bears are also present in smaller numbers in parts of central Asia (former Soviet states).
+The largest brown bear population in Europe is in Russia, where it has now recovered from an all-time low caused by intensive hunting. Populations in Baltoscandia are similarly, albeit slowly, increasing. They include almost 3,000 bears in Sweden, 2,000 in Finland, 1,100 in Estonia and around 100 in Norway.
+Large populations can also be found in Romania (around 6,000), Slovakia (around 1,200), Bosnia and Herzegovina, Croatia (1,200), Slovenia (500-700), North Macedonia, Bulgaria, Poland, Turkey, and Georgia.
+Small but still significant populations can also be found in Albania, Greece, Serbia and Montenegro. In 2005, there were an estimated 200 in Ukraine; these populations are part of two distinct metapopulations: the Carpathian with over 5000 individuals, and the Dinaric-Pindos (Balkans) with around 3000 individuals.There is a small but growing population (at least 70 bears) in the Pyrenees, on the border between Spain and France, which was once on the edge of extinction, as well as two subpopulations in the Cantabrian Mountains in Spain (amounting to around 250 individuals). There are also populations totalling around 100 bears in the Abruzzo, South Tyrol and Trentino regions of Italy. Bears from the aforementioned Italian regions occasionally cross over to bordering Switzerland, which has not hosted a native population since its last bear was shot and killed in Graubünden in 1904.Outside Europe and Russia/the CIS, clades of brown bear persist in small, isolated and for the most part highly threatened populations in Iran, Afghanistan, Pakistan, parts of northwest India and central China, and on the island of Hokkaido in Japan.
+
+
+== Cultural depictions ==
+The historic distribution of bears and the impression the Eurasian brown bear has made on people are reflected in the names of a number of localities (some notable examples include Berlin, Bern, Medvednica, Otepää and Ayu-Dag), as well as personal names—for example, Xiong, Bernard, Arthur, Ursula, Urs, Ursicinus, Orsolya, Björn, Nedved, Medvedev, and Otso.
+Bears of this subspecies appear very frequently in the fairy tales and fables of Europe, in particular tales collected by Jakob and Wilhelm Grimm. The European brown bear was once common in Germany and alpine lands like Northern Italy, Eastern France, and most of Switzerland, and thus appears in tales of various dialects of German.
+The bear is traditionally regarded as the symbol of Russian (military and political) might. It is also Finland's national animal; and in Croatia, a brown bear is depicted on the reverse of the Croatian 5 kuna coin, minted since 1993.These bears are also very common in various stereotypes about Russia.

+The brown bear (Ursus arctos) is a large bear species found across Eurasia and North America. In North America, the populations of brown bears are called grizzly bears, while the subspecies that inhabits the Kodiak Islands of Alaska is known as the Kodiak bear. It is one of the largest living terrestrial members of the order Carnivora, rivaled in size only by its closest relative, the polar bear (Ursus maritimus), which is much less variable in size and slightly bigger on average. The brown bear's range includes parts of Russia, Central Asia, the Himalayas, China, Canada, the United States, Hokkaido, Scandinavia, Finland, the Balkans, the Picos de Europa and the Carpathian region (especially Romania), Iran, Anatolia, and the Caucasus. The brown bear is recognized as a national and state animal in several European countries.While the brown bear's range has shrunk, and it has faced local extinctions across its wide range, it remains listed as a least concern species by the International Union for Conservation of Nature (IUCN) with a total estimated  population in 2017 of 110,000. As of 2012, this and the American black bear are the only bear species not classified as threatened by the IUCN, though the large sizes of both bears may be a disadvantage due to increased competition with humans. Populations that were hunted to extinction in the 19th and 20th centuries are the Atlas bear of North Africa and the Californian, Ungavan and Mexican populations of the grizzly bear of North America. Many of the populations in the southern parts of Eurasia are highly endangered as well. One of the smaller-bodied forms, the Himalayan brown bear, is critically endangered, occupying only 2% of its former range and threatened by uncontrolled poaching for its body parts. The Marsican brown bear of central Italy is one of several currently isolated populations of the Eurasian brown bear and is believed to have a population of just 50 to 60 bears.
+
+
+== Evolution and taxonomy ==
+The brown bear is sometimes referred to as the bruin, from Middle English. This name originated in the fable History of Reynard the Fox translated by William Caxton from Middle Dutch bruun or bruyn, meaning brown (the color). In the mid-19th century United States, the brown bear was termed "Old Ephraim" and sometimes as "Moccasin Joe".The scientific name of the brown bear, Ursus arctos, comes from the Latin ursus, meaning "bear", and from ἄρκτος arktos, the Greek word for bear.
+
+
+=== Generalized names and evolution ===
+Brown bears are thought to have evolved from Ursus etruscus in Asia. The brown bear, per Kurten (1976), has been stated as "clearly derived from the Asian population of Ursus savini about 800,000 years ago; spread into Europe, to the New World." A genetic analysis indicated that the brown bear lineage diverged from the cave bear species complex approximately 1.2–1.4 million years ago, but did not clarify if U. savini persisted as a paraspecies for the brown bear before perishing. The oldest fossils positively identified as from this species occur in China from about 0.5 million years ago. Brown bears entered Europe about 250,000 years ago and North Africa shortly after. Brown bear remains from the Pleistocene period are common in the British Isles, where it is thought they might have outcompeted cave bears (Ursus spelaeus). The species entered Alaska 100,000 years ago, though they did not move south until 13,000 years ago. It is speculated that brown bears were unable to migrate south until the extinction of the much larger giant short-faced bear (Arctodus simus).Several paleontologists suggest the possibility of two separate brown bear migrations: inland brown bears, also known as grizzlies, are thought to stem from narrow-skulled bears which migrated from northern Siberia to central Alaska and the rest of the continent, while Kodiak bears descend from broad-skulled bears from Kamchatka, which colonized the Alaskan peninsula. Brown bear fossils discovered in Ontario, Ohio, Kentucky and Labrador show that the species occurred farther east than indicated in historic records. In North America, two types of the subspecies Ursus arctos horribilis are generally recognized—the coastal brown bear and the inland grizzly bear; these two types broadly define the range of sizes of all brown bear subspecies.
+
+
+=== Scientific taxonomy ===
+
+There are many methods used by scientists to define bear species and subspecies, as no one method is always effective. Brown bear taxonomy and subspecies classification has been described as "formidable and confusing," with few authorities listing the same specific set of subspecies. Genetic testing is now perhaps the most important way to scientifically define brown bear relationships and names. Generally, genetic testing uses the word clade rather than species because a genetic test alone cannot define a biological species. Most genetic studies report on how closely related the bears are (or their genetic distance). There are hundreds of obsolete brown bear subspecies, each with its own name, and this can become confusing; Hall (1981) lists 86 different types, and even as many as 90 have been proposed. However, recent DNA analysis has identified as few as five main clades which contain all extant brown bears, while a 2017 phylogenetic study revealed nine clades, including one representing polar bears. As of 2005, 15 extant or recently extinct subspecies were recognized by the general scientific community.As well as the exact number of overall brown bear subspecies, its precise relationship to the polar bear also remains in debate. The polar bear is a recent offshoot of the brown bear. The point at which the polar bear diverged from the brown bear is unclear, with estimations based on genetics and fossils ranging from 400,000 to 70,000 years ago, but most recent analysis has indicated that the polar bear split somewhere between 275,000 and 150,000 years ago. Under some definitions, the brown bear can be construed as the paraspecies for the polar bear.DNA analysis shows that, apart from recent human-caused population fragmentation, brown bears in North America are generally part of a single interconnected population system, with the exception of the population (or subspecies) in the Kodiak Archipelago, which has probably been isolated since the end of the last Ice Age. These data demonstrate that U. a. gyas, U. a. horribilis, U. a. sitkensis and U. a. stikeenensis are not distinct or cohesive groups, and would more accurately be described as ecotypes. For example, brown bears in any particular region of the Alaska coast are more closely related to adjacent grizzly bears than to distant populations of brown bears, the morphological distinction seemingly driven by brown bears having access to a rich salmon food source, while grizzly bears live at higher elevation, or further from the coast, where plant material is the base of the diet. The history of the bears of the Alexander Archipelago is unusual in that these island populations carry polar bear DNA, presumably originating from a population of polar bears that was left behind at the end of the Pleistocene, but have since been connected with adjacent mainland populations through movement of males, to the point where their nuclear genomes are now more than 90% of brown bear ancestry.Brown bears are apparently divided into five different clades, some of which coexist or co-occur in different regions.
+
+
+=== Hybrids ===
+
+A grizzly–polar bear hybrid (known either as a pizzly bear or a grolar bear) is a rare ursid hybrid resulting from a crossbreeding of a brown bear and a polar bear. It has occurred both in captivity and in the wild. In 2006, the occurrence of this hybrid in nature was confirmed by testing the DNA of a strange-looking bear that had been shot in the Canadian Arctic, and seven more hybrids have since been confirmed in the same region, all descended from a single female polar bear. Previously, the hybrid had been produced in zoos and was considered a "cryptid" (a hypothesized animal for which there is no scientific proof of existence in the wild).
+Analyses of the genomes of bears have shown that introgression between species was widespread during the evolution of the genus Ursus, including the introgression of polar bear DNA introduced to brown bears during the Pleistocene.
+A bear shot in autumn 1986 in Michigan, US, was thought by some to be a grizzly/American black bear hybrid, due to its unusually large size and its proportionately larger braincase and skull. DNA testing was unable to determine whether it was a large American black bear or a grizzly bear.
+
+
+== Description ==
+
+The brown bear is the most variable in size of modern bears. The typical size depends upon which population it is from, and most accepted subtypes vary widely in size. This is in part due to sexual dimorphism, as male brown bears average at least 30% larger in most subtypes. Individual bears also vary in size seasonally, weighing the least in spring due to lack of foraging during hibernation, and the most in late fall, after a period of hyperphagia to put on additional weight to prepare for hibernation. Therefore, a bear may need to be weighed in both spring and fall to get an idea of its mean annual weight.
+
+The normal range of physical dimensions for a brown bear is a head-and-body length of 1.4 to 2.8 m (4 ft 7 in to 9 ft 2 in) and a shoulder height of 70 to 153 cm (2 ft 4 in to 5 ft 0 in). The tail is relatively short, as in all bears, ranging from 6 to 22 cm (2.4 to 8.7 in) in length. The smallest brown bears, females during spring among barren-ground populations, can weigh so little as to roughly match the body mass of males of the smallest living bear species, the sun bear (Helarctos malayanus), while the largest coastal populations attain sizes broadly similar to those of the largest living bear species, the polar bear. Interior brown bears are generally smaller than is often perceived, being around the same weight as an average lion, at an estimate average of 180 kg (400 lb) in males and 135 kg (298 lb) in females, whereas adults of the coastal populations weigh about twice as much. The average weight of adult male bears from 19 populations, from around the world and various subspecies (including both large- and small-bodied subspecies), was found to be 217 kg (478 lb) while adult females from 24 populations were found to average 152 kg (335 lb).
+
+
+=== Color ===
+
+Brown bears are often not fully brown. They have long, thick fur, with a moderately long mane at the back of the neck which varies somewhat across the types. In India, brown bears can be reddish with silver-tipped hairs, while in China brown bears are bicolored, with a yellowish-brown or whitish collar across the neck, chest and shoulders. Even within well-defined subspecies, individuals may show highly variable hues of brown. North American grizzlies can be dark brown (almost black) to cream (almost white) or yellowish-brown and often have darker-colored legs. The common name "grizzly" stems from their typical coloration, with the hairs on their back usually being brownish-black at the base and whitish-cream at the tips, giving them their distinctive "grizzled" color. Apart from the cinnamon subspecies of the American black bear (U. americanus cinnamonum), the brown bear is the only modern bear species to typically appear truly brown. The winter fur is very thick and long, especially in northern subspecies, and can reach 11 to 12 centimetres (4 to 5 in) at the withers. The winter hairs are thin, yet rough to the touch. The summer fur is much shorter and sparser and its length and density varies geographically.
+
+
+=== Cranial morphology and size ===
+
+Adults have massive, heavily built concave skulls, which are large in proportion to the body. The forehead is high and rises steeply. The projections of the skull are well developed when compared to those of Asian black bears (Ursus thibetanus): the latter have sagittal crests not exceeding more than 19–20% of the total length of the skull, while the former have sagittal crests comprising up to 40–41% of the skull's length. Skull projections are more weakly developed in females than in males. The braincase is relatively small and elongated. There is a great deal of geographical variation in the skull, and presents itself chiefly in dimensions. Grizzlies, for example, tend to have flatter profiles than European and coastal American brown bears. Skull lengths of Russian brown bears tend to be 31.5 to 45.5 centimetres (12.4 to 17.9 in) for males, and 27.5 to 39.7 centimetres (10.8 to 15.6 in) for females. The width of the zygomatic arches in males is 17.5 to 27.7 centimetres (6.9 to 11 in), and 14.7 to 24.7 centimetres (5.8 to 9.7 in) in females. Brown bears have very strong teeth: the incisors are relatively big and the canine teeth are large, the lower ones being strongly curved. The first three molars of the upper jaw are underdeveloped and single crowned with one root. The second upper molar is smaller than the others, and is usually absent in adults. It is usually lost at an early age, leaving no trace of the alveolus in the jaw. The first three molars of the lower jaw are very weak, and are often lost at an early age. The teeth of brown bears reflect their dietary plasticity and are broadly similar to other bears, excluding the two most herbivorous living bears, the giant panda (Ailuropoda melanoleuca) and the spectacled bear (Tremarctos ornatus), which have blunt, small premolars (ideal for grinding down fibrous plants) compared to the jagged premolars of ursid bears that at least seasonally often rely on flesh as a food source. The teeth are reliably larger than American black bears, but average smaller in molar length than polar bears. Brown bears have the broadest skull of any extant ursine bear; only the aforementioned most herbivorous living bears exceed them in relative breadth of the skull. Another extant ursine bear, the sloth bear (Melursus ursinus), has a proportionately longer skull than the brown bear and can match the skull length of even large brown bear subtypes, presumably as an aid for foraging heavily on insect colonies for which a long muzzle is helpful as an evolved feature in several unrelated mammalian groups.
+
+
+=== Claws and feet ===
+
+Brown bears have very large and curved claws, those present on the forelimbs being longer than those on the hind limbs. They may reach 5 to 6 centimetres (2.0 to 2.4 in) and may measure 7 to 10 centimetres (2.8 to 3.9 in) along the curve. They are generally dark with a light tip, with some forms having completely light claws. Brown bear claws are longer and straighter than those of American black bears (Ursus americanus). The claws are blunt, while those of a black bear are sharp. Due to their claw structure, in addition to their excessive weight, adult brown bears cannot typically climb trees as well as both species of black bear, although in rare cases adult female brown bears have been seen in trees. The claws of a polar bear are also quite different, being notably shorter but broader with a strong curve and sharper point, presumably both as an aid to traveling over ice (sometimes nearly vertically) and procuring active prey. The paws of the brown bear are quite large. The rear feet of adult bears have been found to typically measure 21 to 36 cm (8.3 to 14.2 in) long, while the forefeet tend to measure about 40% less in length. All four feet in average sized brown bears tend to be about 17.5 to 20 cm (6.9 to 7.9 in) in width. In large coastal or Kodiak bear males, the hindfoot may measure up to 40 cm (16 in) in length, 28.5 cm (11.2 in) in width, while outsized Kodiak bears having had confirmed measurements of up to 46 cm (18 in) along their rear foot. Brown bears are the only extant bears with a hump at the top of their shoulder, which is made entirely of muscle, this feature having developed presumably for imparting more force in digging, which is habitual during foraging for most bears of the species and also used heavily in den construction prior to hibernation. The brown bear's strength has been roughly estimated as 2.5 to 5 times that of a human.
+
+
+== Distribution and habitat ==
+
+Brown bears were once native to Europe, much of Asia, the Atlas Mountains of Africa, and North America, but are now extirpated in some areas, and their populations have greatly decreased in other areas. There are approximately 200,000 brown bears left in the world. The largest populations are in Russia with 120,000, the United States with 32,500, and Canada with around 25,000. Brown bears live in Alaska, east through the Yukon and Northwest Territories, south through British Columbia and through the western half of Alberta. The Alaskan population is estimated at a healthy 32,000 individuals. In the lower 48 states, they are repopulating slowly, but steadily along the Rockies and the western Great Plains.
+In Europe, in 2010, there were 14,000 brown bears in ten fragmented populations, from Spain (estimated at only 20–25 animals in the Pyrenees in 2010, in a range shared between Spain, France and Andorra, and some 210 animals in Asturias, Cantabria, Galicia and León, in the Picos de Europa and adjacent areas in 2013) in the west, to Russia in the east, and from Sweden and Finland in the north to Romania (5000–6000), Bulgaria (900–1200), Slovakia (with about 600–800 animals), Slovenia (500–700 animals) and Greece (with Karamanlidis et al. 2015 estimating >450 animals) in the south.
+In Asia, brown bears are found primarily throughout Russia, thence more spottily southwest to parts of the Middle East, including almost all parts of Kurdistan, to as far south as southwestern Iran, and to the southeast in Northeast China. Brown bears are also found in Western China, Kyrgyzstan, North Korea, Pakistan, Afghanistan and India. They can also be found on the Japanese island of Hokkaidō, which holds the largest number of non-Russian brown bears in eastern Asia with about 2,000–3,000 animals.This species inhabits the broadest range of habitats of any living bear species.
+They seem to have no altitudinal preferences and have been recorded from sea level to an elevation of 5,000 m (16,000 ft) (the latter in the Himalayas). In most of their range, brown bears generally seem to prefer semiopen country, with a scattering of vegetation that can allow them a resting spot during the day. However, they have been recorded as inhabiting every variety of northern temperate forest known to occur.
+
+
+=== Conservation status ===
+While the brown bear's range has shrunk and it has faced local extinctions, it remains listed as a Least concern species by the IUCN, with a total population of approximately 200,000. As of 2012, this and the American black bear are the only bear species not classified as threatened by the IUCN. However, the California grizzly bear, Ungava brown bear, Atlas bear and Mexican grizzly bear, as well as brown bear populations in the Pacific Northwest, were hunted to extinction in the 19th and early 20th centuries and many of the southern Asian subspecies are highly endangered. The Syrian brown bear (Ursus arctos syriacus) is very rare and it has been extirpated from more than half of its historic range. One of the smallest-bodied subspecies, the Himalayan brown bear (Ursus arctos isabellinus), is critically endangered, occupying only 2% of its former range and threatened by uncontrolled poaching for its body parts. The Marsican brown bear in central Italy is believed to have a population of just 50–60 bears.
+
+
+== Behavior and life history ==
+
+The brown bear is often described as nocturnal. However, it frequently seems to peak in activity in the morning and early evening hours. Studies have shown that activity throughout the range can occur at nearly any time of night or day, with bears who dwell in areas with more extensive human contact being more likely to be fully nocturnal. Furthermore, yearling and newly independent bears are more likely to be active diurnally and many adult bears in low-disturbance areas are largely crepuscular. In summer through autumn, a brown bear can double its weight from the spring, gaining up to 180 kg (400 lb) of fat, on which it relies to make it through winter, when it becomes very lethargic. Although they are not full hibernators and can be woken easily, both sexes like to den in a protected spot during the winter months. Hibernation dens may consist of any spot that provides cover from the elements and that can accommodate their bodies, such as a cave, crevice, cavernous tree roots, or hollow logs.Brown bears have one of the largest brains of any extant carnivoran relative to their body size and have been shown to engage in tool use (e.g., using a barnacle-covered rock to scratch its neck), which requires advanced cognitive abilities. This species is mostly solitary, although bears may gather in large numbers at major food sources (e.g.,  open garbage dumps or rivers holding spawning salmon) and form social hierarchies based on age and size. Adult male bears are particularly aggressive and are avoided by adolescent and subadult males, both at concentrated feeding opportunities and chance encounters. Female bears with cubs rival adult males in aggression and are much more intolerant of other bears than single females. Young adolescent males tend to be least aggressive and have been observed in nonantagonistic interactions with each other. Dominance between bears is asserted by making a frontal orientation, showing off canines, muzzle twisting and neck stretching to which a subordinate will respond with a lateral orientation, by turning away and dropping the head and by sitting or lying down. During combat, bears use their paws to strike their opponents in the chest or shoulders and bite the head or neck.
+
+
+=== Communication ===
+
+Several different facial expressions have been documented in brown bears. The "relaxed-face" is made in everyday activities and has the ears pointed to the sides and the mouth closed or slackly open. During social play, bears makes "relaxed open-mouth face" in which the mouth is open, with a curled upper lip and hanging lower lip, and the ears alert and shifting. When looking at another animal at a distance, the bear makes an "alert face" as the ears are cocked and alert, the eyes wide open but the mouth is closed or only open slightly. The "tense closed mouth face" is made with the ears laid back and the mouth closed and occurs when the bear feels threatened. When approached by another individual, the animal makes a "puckered-lip face" with a protruding upper lip and ears which go from cocked and alert when at a certain distance to laid back when closer or when retreating. The "jaw gape face" consists of an open mouth with visible lower canines and hanging lips while the "biting face" is similar to the "relaxed open-mouth face" except the ears are flattened and the eyes are wide enough to expose the sclera. Both the "jaw gape face" and the "biting face" are made in aggression and bears switch between them.Brown bears also produce various vocalizations. Huffing occurs when the animal is tense while woofing is made when alarmed. Both sounds are produced by exhalations though huffing is harsher and is made continuously (two per second). Growls and roars are made in aggression. Growling is harsh and guttural and can range from a simple grrr to a rumble. A rumbling growl can escalate into a roar when the bear is charging. Roaring is described as "thunderous" and can travel 2 km (1.2 mi). Mothers and cubs wanting physical contact will bawl, which is heard as waugh!, waugh!.
+
+
+=== Home ranges ===
+Brown bears usually occur over vast home ranges; however, they are not highly territorial. Several adult bears often roam freely over the same vicinity without issue, unless rights to a fertile female or food sources are being contested. Males always cover more area than females each year. Despite their lack of traditional territorial behavior, adult males can seem to have a "personal zone" in which other bears are not tolerated if they are seen. Males always wander further than females, due to both increasing access to females and food sources, while females are advantaged by smaller territories in part since it decreases the likelihood of encounters with male bears who may endanger their cubs. In areas where food is abundant and concentrated, such as coastal Alaska, home ranges for females are up to 24 km2 (9.3 sq mi) and for males are up to 89 km2 (34 sq mi). Similarly, in British Columbia, bears of the two sexes travel relatively compact home ranges of 115 km2 (44 sq mi) and 318 km2 (123 sq mi). In Yellowstone National Park, home ranges for females are up to 281 km2 (108 sq mi) and up to 874 km2 (337 sq mi) for males. In Romania, the largest home range was recorded for adult males (3,143 km2, 1214 sq mi). In the central Arctic of Canada, where food sources are quite sparse, home ranges range up to 2,434 km2 (940 sq mi) in females and 8,171 km2 (3,155 sq mi) in males.A study of male-inherited Y chromosome DNA sequence found that brown bears, over the past few 10,000 years, have shown strong male-biased dispersal. That study found surprisingly similar Y chromosomes in brown bear populations as far apart as Norway and coastal Alaska, indicating extensive gene flow across Eurasia and North America. Notably, this contrasts with genetic signals from female-inherited mitochondrial DNA (mtDNA), where brown bears of different geographic regions typically show strong differences in their mtDNA, a result of female philopatry.
+
+
+=== Reproduction ===
+
+The mating season is from mid-May to early July, shifting later the further north the bears are found. Being serially monogamous, brown bears remain with the same mate from a couple of days to a couple of weeks. Outside of this narrow time frame, adult male and female brown bears show no sexual interest in each other. Females mature sexually between the age of four and eight years of age, with an average age at sexual maturity of 5.2–5.5 years old, while males first mate about a year later on average, when they are large and strong enough to successfully compete with other males for mating rights. Males will try to mate with as many females as they can; usually a successful one mates with two females in a span of one to three weeks. The adult female brown bear is similarly promiscuous, mating with up to four, rarely even eight, males while in heat and potentially breeding with two males in a single day. Females come into oestrus on average every three to four years, with a full range of 2.4 to 5.7 years. The urine markings of a female in oestrus can attract several males via scent. Paternity DNA tests have shown that littermates do not share the same father in up to 29% of litters. Dominant males may try to sequester a female for her entire oestrus period of approximately two weeks, but usually are unable to retain her for the entire time. Copulation is vigorous and prolonged and can last up to an hour, although the mean time is about 23–24 minutes.
+
+Males take no part in raising their cubs – parenting is left entirely to the females. Through the process of delayed implantation, a female's fertilized egg divides and floats freely in the uterus for six months. During winter dormancy, the fetus attaches to the uterine wall. The cubs are born eight weeks later while the mother sleeps. If the mother does not gain enough weight to survive through the winter while gestating, the embryo does not implant and is reabsorbed into the body. There have been cases of brown bears with as many as six cubs, although the average litter size is one to three, with more than four being considered uncommon. There are records of females sometimes adopting stray cubs or even trading or kidnapping cubs when they emerge from hibernation (a larger female may claim cubs away from a smaller one). Older and larger females within a population tend to give birth to larger litters. The size of a litter also depends on factors such as geographic location and food supply. At birth, the cubs are blind, toothless and hairless and may weigh from 350 to 510 g (0.77 to 1.12 lb), again reportedly based on the age and condition of the mother. They feed on their mother's milk until spring or even early summer, depending on climate conditions. At this time, the cubs weigh 7 to 9 kg (15 to 20 lb) and have developed enough to follow her over long distances and begin to forage for solid food.
+
+The cubs are fully dependent on the mother and a close bond is formed. During the dependency stage, the cubs learn (rather than inherit as instincts from birth) survival techniques, such as which foods have the highest nutritional value and where to obtain them; how to hunt, fish and defend themselves; and where to den. Increased brain size in large carnivores has been positively linked to whether a given species is solitary, as is the brown bear, or raises their offspring communally, thus female brown bears have relatively large, well-developed brains, presumably key in teaching behavior. The cubs learn by following and imitating their mother's actions during the period they are with her. Cubs remain with their mother for an average of 2.5 years in North America, uncommonly being independent as early as 1.5 years of age or as late as 4.5 years of age. The stage at which independence is attained may generally be earlier in some parts of Eurasia, as the latest date which mother and cubs were together was 2.3 years, most families separated in under two years in a study from Hokkaido and in Sweden most cubs on their own were still yearlings. Brown bears practice infanticide, as an adult male bear may kill the cubs of a another. When an adult male brown bear kills a cub, it is usually because he is trying to bring the female into oestrus, as she will enter that state within two to four days after the death of her cubs. Cubs flee up a tree, if available, when they see a strange male bear and the mother often successfully defends them, even though the male may be twice as heavy as she, although females have been known to die in these confrontations.
+
+
+=== Dietary habits ===
+
+The brown bear is one of the most omnivorous animals in the world and has been recorded as consuming the greatest variety of foods of any bear. Throughout life, this species is regularly curious about the potential of eating virtually any organism or object that they encounter. Food that is both abundant and easily accessed or caught is preferred. Their jaw structure has evolved to fit their dietary habits. Their diet varies enormously throughout their differing areas based on opportunity.
+Despite their reputation, most brown bears are not highly carnivorous, as they derive up to 90% of their dietary food energy from vegetable matter. They often feed on a variety of plant life, including berries, grasses, flowers, acorns and pine cones, as well as fungi such as mushrooms. Among all bears, brown bears are uniquely equipped to dig for tough foods such as roots, bulbs and shoots. They use their long, strong claws to dig out earth to reach the roots and their powerful jaws to bite through them. In spring, winter-provided carrion, grasses, shoots, sedges, moss and forbs are the dietary mainstays for brown bears internationally. Fruits, including berries, become increasingly important during summer and early autumn. Roots and bulbs become critical in autumn for some inland bear populations if fruit crops are poor. They will also commonly consume animal matter, which in summer and autumn may regularly be in the form of insects, larvae and grubs, including beehives. Bears in Yellowstone eat an enormous number of moths during the summer, sometimes as many as 40,000 Army cutworm moths in a single day, and may derive up to half of their annual food energy from these insects. Brown bears living near coastal regions will regularly eat crabs and clams. In Alaska, bears along the beaches of estuaries regularly dig through the sand for clams. This species may eat birds and their eggs, including almost entirely ground- or rock-nesting species. The diet may be supplemented by rodents or similar smallish mammals, including marmots, ground squirrels, mice, rats, lemmings and voles. With particular regularity, bears in Denali National Park will wait at burrows of Arctic ground squirrels hoping to pick off a few of the 1 kg (2.2 lb) rodents.In the Kamchatka peninsula and several parts of coastal Alaska, brown bears feed mostly on spawning salmon, whose nutrition and abundance explain the enormous size of the bears in these areas. The fishing techniques of bears are well-documented. They often congregate around falls when the salmon are forced to breach the water, at which point the bears will try to catch the fish in mid-air (often with their mouths). They will also wade into shallow waters, hoping to pin a slippery salmon with their claws. While they may eat almost all the parts of the fish, bears at the peak of spawning, when there is usually a glut of fish to feed on, may eat only the most nutrious parts of the salmon (including the eggs and head) and then indifferently leave the rest of the carcass to scavengers, which can include red foxes, bald eagles, common ravens and gulls. Despite their normally solitary habits, brown bears will gather rather closely in numbers at good spawning sites. The largest and most powerful males claim the most fruitful fishing spots and bears (especially males) will sometimes fight over the rights to a prime fishing spot.
+
+Beyond the regular predation of salmon, most brown bears are not particularly active predators. While perhaps a majority of bears of the species will charge at large prey at one point in their lives and most eat carrion, many predation attempts start with the bear clumsily and half-heartedly pursuing the prey and end with the prey escaping alive. On the other hand, some brown bears are quite self-assured predators who habitually pursue and catch large prey items. Such bears are usually taught how to hunt by their mothers from an early age. Large mammals preyed on can include various ungulate species such as elk, moose, caribou, muskoxen and wild boar, When brown bears attack these large animals, they usually target young or infirm ones, as they are easier to catch. Typically when hunting (especially with young prey), the bear pins its prey to the ground and then immediately tears and eats it alive. It will also bite or swipe some prey to stun it enough to knock it over for consumption. To pick out young or infirm individuals, bears will charge at herds so the slower-moving and more vulnerable individuals will be made apparent. Brown bears may also ambush young animals by finding them via scent. When emerging from hibernation, brown bears, whose broad paws allow them to walk over most ice and snow, may pursue large prey such as moose whose hooves cannot support them on encrusted snow. Similarly, predatory attacks on large prey sometimes occur at riverbeds, when it is more difficult for the prey specimen to run away due to muddy or slippery soil. On rare occasions, while confronting fully-grown, dangerous prey, bears kill them by hitting with their powerful forearms, which can break the necks and backs of large creatures such as adult moose and adult bison. They also feed on carrion, and use their size to intimidate other predators, such as wolves, cougars, tigers, and American black bears from their kills. Carrion is especially important in the early spring (when the bears are emerging from hibernation), much of it comprising winter-killed big game. Cannibalism is not unheard of, though predation is not normally believed to be the primary motivation when brown bears attack each other.When forced to live in close proximity with humans and their domesticated animals, bears may potentially predate any type of domestic animal. Among these, domestic cattle are sometimes exploited as prey. Cattle are bitten on the neck, back or head and then the abdominal cavity is opened for eating. Plants and fruit farmed by humans are readily consumed as well, including corn, wheat, sorghum, melons and any form of berries. They will also feed at domestic bee yards, readily consuming both honey and the brood (grubs and pupae) of the honey bee colony. Human foods and trash or refuse is eaten when possible. When an open garbage dump was kept in Yellowstone, brown bears were one of the most voracious and regular scavengers. The dump was closed after both brown and American black bears came to associate humans with food and lost their natural fear of them.
+
+
+=== Interspecific predatory relationships ===
+
+Adult bears are generally immune to predatory attacks except from tigers and other bears. Siberian tigers prefer preying on young Ussuri brown bears, but smaller adult female brown bears outside their dens may also be taken, generally when lethargic from hibernation. Of 44 recorded encounters between the two predators, 20 resulted in confrontations; in 50% of these, the bears were killed, in 27% the tigers were killed, and 23% of the cases ended with both animals surviving and parting ways. Some bears emerging from hibernation seek out tigers in order to steal their kills. Some large brown bears may actually benefit from the tiger's presence by appropriating tiger kills that the bears may not be able to successfully hunt themselves and follow tiger tracks. Geptner et al. (1972) stated bears are generally afraid of tigers and change their path after coming across tiger trails. In the winters of 1970–1973, Yudakov and Nikolaev recorded 1 case of brown bear showing no fear of the tigers and another case of brown bear changing path upon crossing tiger tracks. Other researchers have observed bears following tiger tracks for various reasons.Brown bears regularly intimidate wolves to drive them away from their kills. In Yellowstone National Park, bears pirate wolf kills so often, Yellowstone's Wolf Project director Doug Smith wrote, "It's not a matter of if the bears will come calling after a kill, but when." Despite the high animosity between the two species, most confrontations at kill sites or large carcasses end without bloodshed on either side. Though conflict over carcasses is common, on rare occasions, the two predators tolerate each other on the same kill. To date, there is a single case of fully-grown wolves being killed by a grizzly bear. Given the opportunity, however, both species will prey on the other's cubs. Conclusively, the individual power of the bear against the collective strength of the wolf pack usually results in a long battle for kills or domination.
+In some areas, grizzly bears also regularly displace cougars from their kills. Cougars kill small bear cubs on rare occasions, but there was one report of a bear killing a cougar of unknown age and condition between 1993 and 1996. Smaller carnivorous animals, including coyotes, wolverines, lynxes, and any other sympatric carnivores or raptorial birds, are dominated by grizzly bears and generally avoid direct interactions with them, unless attempting to steal scraps of food. However, wolverines have been persistent enough to fend off a grizzly bear as much as ten times their weight off a kill. There is one record of a golden eagle preying on a brown bear cub.Brown bears usually dominate other bear species in areas where they coexist. Due to their smaller size, American black bears are at a competitive disadvantage to grizzly bears in open, unforested areas. Although displacement of black bears by grizzly bears has been documented, actual interspecific killing of black bears by grizzlies has only occasionally been reported. Confrontation is mostly avoided due to the black bear's diurnal habits and preference for heavily forested areas, as opposed to the grizzly's largely nocturnal habits and preference for open spaces. Brown bears may also kill Asian black bears, though the latter species probably largely avoids conflicts with the brown bear, due to similar habits and habitat preferences to the American black species. They will eat the fruit dropped by the Asian black bear from trees, as they themselves are too large and cumbersome to climb.  Improbably, in the Himalayas Brown bears are reportedly intimidated by Asian black bears in confrontations.There has been a recent increase in interactions between brown bears and polar bears, theorized to be caused by climate change. Brown and grizzly bears have been seen moving increasingly northward into territories formerly claimed by polar bears. They tend to dominate polar bears in disputes over carcasses, and dead polar bear cubs have been found in brown bear dens.
+
+
+=== Longevity and mortality ===
+
+The brown bear has a naturally long life. Wild females have been observed reproducing up to 28 years of age, which is the oldest known age for reproduction of any ursid in the wild. The peak reproductive age for females ranges from four to 20 years old. The lifespan of brown bears of both sexes within minimally hunted populations is estimated at an average of 25 years. The oldest wild brown bear on record was nearly 37 years old. The oldest recorded female in captivity was nearly 40 years old, while males in captivity have been verified to live up to 47 years, with one captive male possibly attaining 50 years of age.While male bears potentially live longer in captivity, female grizzly bears have a greater annual survival rate than males within wild populations per a study done in the Greater Yellowstone Ecosystem. Annual mortality for bears of any age is estimated at 10% in most protected areas; however, the average annual mortality rate rises to an estimated 38% in hunted populations. Around 13% to 44% of cubs die within their first year even in well-protected areas. Mortality rates of 75–100% among the cubs of any given year are not uncommon. Beyond predation by large predators including wolves, Siberian tigers and other brown bears, starvation and accidents also claim the lives of cubs. Studies have indicated that the most prevalent source of mortality for first-year cubs is malnutrition. By the second and third years of their lives, the annual mortality rate among cubs in the care of their mothers drops to 10-15%.Even in populations living in protected areas, humans are still the leading cause of mortality for brown bears. The largest amount of legalized brown bear hunting occurs in Canada, Finland, Russia, Slovakia and Alaska. Hunting is unregulated in many areas within the range of the brown bear. Even where hunting is legally permitted, most biologists feel that the numbers hunted are excessive considering the low reproduction rate and sparse distribution of the species. Brown bears are also killed in collisions with automobiles, which is a significant cause of mortality in the United States and Europe.
+
+
+== Relationship with humans ==
+
+
+=== Conflicts between bears and humans ===
+
+Brown bears usually avoid areas where extensive development or urbanization has occurred, unlike the smaller, more inoffensive American black bear which can adapt to peri-urban regions. Under many circumstances, extensive human development may cause brown bears to alter their home ranges. High road densities (both paved and gravel roads) are often associated with higher mortality, habitat avoidance and lower bear density. However, brown bears can easily lose their natural cautiousness upon being attracted to human-created food sources, such as garbage dumps, litter bins and dumpsters. Brown bears may even venture into human dwellings or barns in search of food as humans encroach on bear habitats. In other areas, such as Alaska, dumps may continue to be an attractant for brown bears. In different parts of their distribution, brown bears sometimes kill and eat domesticated animals. The saying "A fed bear is a dead bear" has come into use to popularize the idea that allowing a bear to scavenge human garbage, such as trash cans and campers' backpacks, pet food, or other food sources that draw the bear into contact with humans, can result in the bear's death. Results of a 2016 study performed in a southeastern British Columbian valley indicate that areas where attractive bear food and concentrated human settlements overlap, human-bear conflict can create an ecological trap resulting in a lower apparent survival rate for brown bears, as well as attracting additional bears and thereby causing overall population declines.When brown bears come to associate human activity with a "food reward", they are likely to continue to become emboldened; the likelihood of human-bear encounters increases, as they may return to the same location despite relocation. Relocation of the bear has been used to separate the bear from the human environment, but it does not address the problem of the bear's newly learned association of humans with food or the environmental situations which created the human-habituated bear. "Placing a bear in habitat used by other bears may lead to competition and social conflict, and result in the injury or death of the less dominant bear." Yellowstone National Park, a reserve located in the western United States, contains prime habitat for the grizzly bear (Ursus arctos horribilis) and due to the enormous number of visitors, human-bear encounters are common. The scenic beauty of the area has led to an influx of people moving into the area. In addition, because there are so many bear relocations to the same remote areas of Yellowstone, and because male bears tend to dominate the center of the relocation zone, female bears tend to be pushed to the boundaries of the region and beyond. As a result, a large proportion of repeat offenders, bears that are killed for public safety, are females. This creates a further depressive effect on an already-endangered subspecies. The grizzly bear is officially described as "Threatened" in the U.S.. Although the problem is most significant with regard to grizzlies, these issues affect the other types of brown bears as well.In Europe, part of the problem lies with shepherds; over the past two centuries, many sheep and goat herders have gradually abandoned the more traditional practice of using dogs to guard flocks, which have concurrently grown larger. Typically, they allow the herds to graze freely over sizeable tracts of land. As brown bears reclaim parts of their range, they may eat livestock as sheep and goats are relatively easy for a bear to kill. In some cases, the shepherds shoot the bear, thinking their livelihood is under threat. Many are now better informed about the ample compensation available and will make a claim when they lose livestock to a bear. Another issue in several parts of their range in Europe is supplemental feeding stations where various kind of animal carrion is offered, which are set up mainly in Scandinavia and eastern Europe both to support the locally threatened species and so humans can enjoy watching bears that may otherwise prove evasive. Despite that most stations were cautiously set in remote areas far from human habitations, some brown bears in such areas have become conditioned to associate humans with food and become excessively bold "problem bears". Also, supplemental feeding appears to cause no decrease in livestock predation.
+
+
+=== Bear encounters and attacks ===
+
+Brown bears seldom attack humans on sight and usually avoid people. In Russia, it is estimated that 1 in 1,000 on-foot encounters with brown bears results in an attack. They are, however, unpredictable in temperament, and may attack if they are surprised or feel threatened. There are an average of two fatal attacks by bears per year in North America. In Scandinavia, there are only four known cases since 1902 of bear encounters which have resulted in death. The two most common causes for bear attack are surprise and curiosity. Some types of bears, such as polar bears, are more likely to attack humans when searching for food, while American black bears are much less likely to attack. Despite their boldness and potential for predation if the bear is hungry, polar bears rarely attack humans, because they are infrequently encountered in the Arctic sea. Aggressive behavior in brown bears is favored by numerous selection variables. Increased aggressiveness also assists female brown bears in better ensuring the survival of their young to reproductive age. Mothers defending cubs are the most prone to attacking, being responsible for 70% of brown bear-caused human fatalities in North America.Sows with cubs account for many attacks on humans by brown bears in North America. Habituated or food-conditioned bears can also be dangerous, as their long-term exposure to humans causes them to lose their natural shyness and, in some cases, to associate humans with food. Small parties of one or two people are more often attacked by brown bears than large groups, with only one known case of an attack on a group of six or more. In that instance, it is thought that due to surprise, the grizzly bear may not have recognized the size of the group. In the majority of attacks resulting in injury, brown bears precede the attack with a growl or huffing sound. In contrast to injuries caused by American black bears, which are usually minor, brown bear attacks more often tend to result in serious injury and, in some cases, death. Brown bears seem to confront humans as they would when fighting other bears: they rise up on their hind legs, and attempt to "disarm" their victims by biting and holding on to the lower jaw to avoid being bitten in turn. Due to the bears' enormous physical strength, even a single bite or swipe can be deadly as in tigers, with some human victims having had their heads completely crushed by a bear bite. Most attacks occur in the months of July, August and September, the time when the number of outdoor recreationalists, such as hikers or hunters, is higher. People who assert their presence through noises tend to be less vulnerable, as they alert bears to their presence. In direct confrontations, people who run are statistically more likely to be attacked than those who stand their ground. Violent encounters with brown bears usually last only a few minutes, though they can be prolonged if the victims fight back. In Alberta, two common behaviors by human hunters, imitating the calls of deer to attract them and carrying ungulate carcasses, seem to court aggressive behavior and lead to a higher rate of attack from grizzly bears.Attacks on humans are considered extremely rare in the former Soviet Union, though exceptions exist in districts where they are not as often pursued by hunters. East Siberian brown bears, for example, tend to be much bolder toward humans than their shyer, more persecuted European counterparts. The delineation in Eurasia between areas where aggressiveness of brown bears tends to increase is the Ural Mountains, although the brown bears of eastern Europe are somewhat more aggressive than those of western Europe. In 2008, a platinum mining compound in the Olyotorsky district of northern Kamchatka was besieged by a group of 30 bears, who killed two guards and prevented workers from leaving their homes. 10 people a year on average are killed by brown bears in Russia, more than all the other parts of the brown bear's international range combined, although Russia also holds more brown bears than all other parts of the world combined. In Scandinavia, only three fatal attacks were recorded in the 20th century.In Japan, a large brown bear nicknamed "Kesagake" (袈裟懸け, "kesa-style slasher") made history for causing the worst brown bear attack in Japanese history at Tomamae, Hokkaidō during numerous encounters during December 1915. It killed seven people and wounded three others (with possibly another three previous fatalities to its credit) before being gunned down after a large-scale beast-hunt. Today, there is still a shrine at Rokusensawa (六線沢), where the event took place in memory of the victims of the incident.Within Yellowstone National Park, injuries caused by grizzly attacks in developed areas averaged approximately one per year during the 1930s through to the 1950s, though it increased to four per year during the 1960s. They then decreased to one injury every two years during the 1970s. Between 1980 and 2002, there have been only two human injuries caused by grizzly bears in a developed area. Although grizzly attacks were rare in the backcountry before 1970, the number of attacks increased to an average of approximately one per year during the 1970s, 1980s and 1990s. In Alberta, from 1960 to 1998, the number of attacks by grizzly bears ending in injury were nearly three times more common than attacks ending in injury by American black bears, despite the American black bear being an estimated 38 times more numerous in the province than the grizzly bear.
+
+
+=== History of defense from bears ===
+
+A study by U.S. and Canadian researchers has found bear spray to be more effective at stopping aggressive bear behavior than guns, working in 92% of studied incidents versus 67% for guns. Carrying pepper spray is highly recommended by many authorities when traveling in bear country; however, carrying two means of deterrent, one of which is a large caliber gun, is also advised. Solid shotgun slugs, or three buckshot rounds, or a pistol of .44 caliber or more is suggested if a heavy hunting rifle is not available. Guns remain a viable, last resort option to be used in defense of life from aggressive brown bears. Too often, people do not carry a proper caliber weapon to neutralize the bear. According to the Alaska Science Center, a 12-gauge shotgun with slugs has been the most effective weapon. There have been fewer injuries as a result of only carrying lethal loads in the shotgun, as opposed to deterrent rounds. State of Alaska Defense of Life or Property (DLP) laws require one to report the kill to the authorities and salvage the hide, skull and claws. A page at the State of Alaska Department of Natural Resources website offers information about how to "select a gun that will stop a bear (12-gauge shotgun or .300 mag rifle)".Campers are often told to wear bright-colored red ribbons and bells and carry whistles to ward off bears. They are told to look for grizzly bear dung in camping areas and be careful to carry the bells and whistles in those areas. Grizzly bear dung is difficult to differentiate from American black bear dung, as diet is in a constant state of flux depending on the availability of seasonal food items. If a bear is killed near camp, the bear's carcass must be adequately disposed of, including entrails and blood, if possible. Failure to move the carcass has often resulted in it attracting other bears and further exacerbating a bad situation. Moving camps immediately is another recommended method.
+
+
+=== Culture ===
+
+Brown bears often figure into the literature of Europe and North America, in particular that which is written for children. "The Brown Bear of Norway" is a Scottish fairy tale telling the adventures of a girl who married a prince magically turned into a bear and who managed to get him back into a human form by the force of her love and after many trials and difficulties. With "Goldilocks and the Three Bears", a story from England, the Three Bears are usually depicted as brown bears. In German-speaking countries, children are often told the fairytale of "Snow White and Rose Red"; the handsome prince in this tale has been transfigured into a brown bear. In the United States, parents often read their preschool age children the book Brown Bear, Brown Bear, What Do You See? to teach them their colors and how they are associated with different animals.The Russian bear is a common national personification for Russia (as well as the former Soviet Union), despite the country having no appointed national animal. The brown bear is Finland's national animal.The grizzly bear is the state animal of Montana. The California golden bear is the state animal of California. Both animals are subspecies of the brown bear and the species was extirpated from the latter state.
+The coat of arms of Madrid depicts a bear reaching up into a madroño or strawberry tree (Arbutus unedo) to eat some of its fruit, whereas the Swiss city of Bern's coat of arms also depicts a bear and the city's name is popularly thought to derive from the German word for bear. The brown bear is depicted on the reverse of the Croatian 5 kuna coin, minted since 1993.
+The Bundesliga club Bayern Munich has a brown bear mascot named Berni. The Chicago National Football League (NFL) franchise is named the Bears. In this context, no differentiation between American black and brown bears is needed. The school mascot for Bob Jones University, Brown University, Cornell University, George Fox University, the University of Alberta, the University of California, Berkeley, the University of California, Los Angeles, the University of California, Riverside, and numerous American high schools is the brown bear.
+In the town of Prats de Molló, in Vallespir, French Catalonia, a "bear festival" (festa de l'ós) is celebrated annually at the beginning of spring, in which the locals dress up as bears, cover themselves with soot or coal and oil and "attack" the onlookers, attempting to get everyone dirty. The festival ends with the ball de l'ós (bear dance).

+The Komodo dragon (Varanus komodoensis), also known as the Komodo monitor, is a member of the monitor lizard family Varanidae that is endemic to the Indonesian islands of Komodo, Rinca, Flores, and Gili Motang. It is the largest extant species of lizard, growing to a maximum length of 3 metres (10 ft), and weighing up to 70 kilograms (150 lb).
+As a result of their size, Komodo dragons are apex predators, and dominate the ecosystems in which they live. Komodo dragons hunt and ambush prey including invertebrates, birds, and mammals. It has been claimed that they have a venomous bite; there are two glands in the lower jaw that secrete several toxic proteins. The biological significance of these proteins is disputed, but the glands have been shown to secrete an anticoagulant. Komodo dragons' group behavior in hunting is exceptional in the reptile world. The diet of Komodo dragons mainly consists of Javan rusa (Rusa timorensis), though they also eat considerable amounts of carrion. Komodo dragons also occasionally attack humans.
+Mating begins between May and August, and the eggs are laid in September; as many as 20 eggs are deposited at a time in an abandoned megapode nest or in a self-dug nesting hole. The eggs are incubated for seven to eight months, hatching in April, when insects are most plentiful. Young Komodo dragons are vulnerable and dwell in trees to avoid predators, such as cannibalistic adults. They take 8 to 9 years to mature and are estimated to live up to 30 years.
+Komodo dragons were first recorded by Western scientists in 1910. Their large size and fearsome reputation make them popular zoo exhibits. In the wild, their range has contracted due to human activities, and is likely to contract further from the effects of climate change; due to this, they are listed as Endangered by the IUCN Red List. They are protected under Indonesian law, and Komodo National Park was founded in 1980 to aid protection efforts.
+
+
+== Taxonomic history ==
+
+Komodo dragons were first documented by Europeans in 1910, when rumors of a "land crocodile" reached Lieutenant van Steyn van Hensbroek of the Dutch colonial administration. Widespread notoriety came after 1912, when Peter Ouwens, the director of the Zoological Museum of Bogor, Java, published a paper on the topic after receiving a photo and a skin from the lieutenant, as well as two other specimens from a collector.The first two live Komodo dragons to arrive in Europe were exhibited in the Reptile House at London Zoo when it opened in 1927. Joan Beauchamp Procter made some of the earliest observations of these animals in captivity and she demonstrated their behaviour at a Scientific Meeting of the Zoological Society of London in 1928.The Komodo dragon was the driving factor for an expedition to Komodo Island by W. Douglas Burden in 1926. After returning with 12 preserved specimens and two live ones, this expedition provided the inspiration for the 1933 movie King Kong. It was also Burden who coined the common name "Komodo dragon". Three of his specimens were stuffed and are still on display in the American Museum of Natural History.The Dutch island administration, realizing the limited number of individuals in the wild, soon outlawed sport hunting and heavily limited the number of individuals taken for scientific study. Collecting expeditions ground to a halt with the occurrence of World War II, not resuming until the 1950s and 1960s, when studies examined the Komodo dragon's feeding behavior, reproduction, and body temperature. At around this time, an expedition was planned in which a long-term study of the Komodo dragon would be undertaken. This task was given to the Auffenberg family, who stayed on Komodo Island for 11 months in 1969. During their stay, Walter Auffenberg and his assistant Putra Sastrawan captured and tagged more than 50 Komodo dragons.Research from the Auffenberg expedition proved to be enormously influential in raising Komodo dragons in captivity. Research after that of the Auffenberg family has shed more light on the nature of the Komodo dragon, with biologists such as Claudio Ciofi continuing to study the creatures.
+
+
+=== Etymology ===
+
+The Komodo dragon is also sometimes known as the Komodo monitor or the Komodo Island monitor in scientific literature, although this name is uncommon. To the natives of Komodo Island, it is referred to as ora, buaya darat ('land crocodile'), or biawak raksasa ('giant monitor').
+
+
+=== Evolutionary history ===
+The evolutionary development of the Komodo dragon started with the genus Varanus, which originated in Asia about 40 million years ago and migrated to Australia, where it evolved into giant forms (the largest of all being the recently extinct Varanus priscus, or "Megalania"), helped by the absence of competing placental carnivorans. Around 15 million years ago, a collision between the continental landmasses of Australia and Southeast Asia allowed these larger varanids to move back into what is now the Indonesian archipelago, extending their range as far east as the island of Timor.
+The Komodo dragon is believed to have differentiated from its Australian ancestors about 4 million years ago. However, fossil evidence from Queensland suggests the Komodo dragon actually evolved in Australia, before spreading to Indonesia.Dramatic lowering of sea level during the last glacial period uncovered extensive stretches of continental shelf that the Komodo dragon colonised, becoming isolated in their present island range as sea levels rose afterwards. Fossils of extinct Pliocene species of similar size to the modern Komodo dragon, such as Varanus sivalensis, have been found in Eurasia as well, indicating that they fared well even in environments containing competition, such as mammalian carnivores, until the climate change and extinction events that marked the beginning of the Pleistocene.Genetic analysis of mitochondrial DNA shows the Komodo dragon to be the closest relative (sister taxon) of the lace monitor (V. varius), with their common ancestor diverging from a lineage that gave rise to the crocodile monitor (Varanus salvadorii) of New Guinea. A 2021 study showed that during the Miocene, Komodo dragons had hybridized with the ancestors of the Australian sand monitor (V. gouldii), thus providing further evidence that the Komodo dragon had once inhabited Australia. Genetic analysis indicates that the population from northern Flores is genetically distinct from other populations of the species.
+
+
+== Description ==
+
+In the wild, adult Komodo dragons usually weigh around 70 kg (150 lb), although captive specimens often weigh more. According to Guinness World Records, an average adult male will weigh 79 to 91 kg (174 to 201 lb) and measure 2.59 m (8.5 ft), while an average female will weigh 68 to 73 kg (150 to 161 lb) and measure 2.29 m (7.5 ft). The largest verified specimen in captive was 3.13 m (10.3 ft) long and weighed 166 kg (366 lb), including its undigested food. The largest wild specimen had a length 3.04 m (10.0 ft), a snout-vent length (SVL) 1.54 m (5 ft 1 in) and a mass of 81.5 kg (180 lb) excluding stomach contents. The heaviest reached a mass in 87.4 kg (193 lb).  The study noted that weights greater than 100 kg (220 lb) were possible but only after the animal had consumed a large meal.
+
+The Komodo dragon has a tail as long as its body, as well as about 60 frequently replaced, serrated teeth that can measure up to 2.5 cm (1 in) in length. Its saliva is frequently blood-tinged because its teeth are almost completely covered by gingival tissue that is naturally lacerated during feeding. It also has a long, yellow, deeply forked tongue. Komodo dragon skin is reinforced by armoured scales, which contain tiny bones called osteoderms that function as a sort of natural chain-mail. The only areas lacking osteoderms on the head of the adult Komodo dragon are around the eyes, nostrils, mouth margins, and pineal eye, a light-sensing organ on the top of the head. Where lizards typically have one or two varying patterns or shapes of osteoderms, komodos have four: rosette, platy, dendritic, and vermiform. This rugged hide makes Komodo dragon skin a poor source of leather. Additionally, these osteoderms become more extensive and variable in shape as the Komodo dragon ages, ossifying more extensively as the lizard grows. These osteoderms are absent in hatchlings and juveniles, indicating that the natural armor develops as a product of age and competition between adults for protection in intraspecific combat over food and mates.
+
+
+=== Senses ===
+
+As with other varanids, Komodo dragons have only a single ear bone, the stapes, for transferring vibrations from the tympanic membrane to the cochlea. This arrangement means they are likely restricted to sounds in the 400 to 2,000 hertz range, compared to humans who hear between 20 and 20,000 hertz. They were formerly thought to be deaf when a study reported no agitation in wild Komodo dragons in response to whispers, raised voices, or shouts. This was disputed when London Zoological Garden employee Joan Procter trained a captive specimen to come out to feed at the sound of her voice, even when she could not be seen.The Komodo dragon can see objects as far away as 300 m (980 ft), but because its retinas only contain cones, it is thought to have poor night vision. It can distinguish colours, but has poor visual discrimination of stationary objects.As with many other reptiles, the Komodo dragon primarily relies on its tongue to detect, taste, and smell stimuli, with the vomeronasal sense using the Jacobson's organ, rather than using the nostrils. With the help of a favorable wind and its habit of swinging its head from side to side as it walks, a Komodo dragon may be able to detect carrion from 4–9.5 km (2.5–5.9 mi) away. It only has a few taste buds in the back of its throat. Its scales, some of which are reinforced with bone, have sensory plaques connected to nerves to facilitate its sense of touch. The scales around the ears, lips, chin, and soles of the feet may have three or more sensory plaques.
+
+
+== Behaviour and ecology ==
+
+The Komodo dragon prefers hot and dry places and typically lives in dry, open grassland, savanna, and tropical forest at low elevations. As an ectotherm, it is most active in the day, although it exhibits some nocturnal activity. Komodo dragons are solitary, coming together only to breed and eat. They are capable of running rapidly in brief sprints up to 20 km/h (12 mph), diving up to 4.5 m (15 ft), and climbing trees proficiently when young through use of their strong claws. To catch out-of-reach prey, the Komodo dragon may stand on its hind legs and use its tail as a support. As it matures, its claws are used primarily as weapons, as its great size makes climbing impractical.For shelter, the Komodo dragon digs holes that can measure from 1 to 3 m (3.3 to 9.8 ft) wide with its powerful forelimbs and claws. Because of its large size and habit of sleeping in these burrows, it is able to conserve body heat throughout the night and minimise its basking period the morning after. The Komodo dragon hunts in the afternoon, but stays in the shade during the hottest part of the day. These special resting places, usually located on ridges with cool sea breezes, are marked with droppings and are cleared of vegetation. They serve as strategic locations from which to ambush deer.
+
+
+=== Diet ===
+
+Komodo dragons are apex predators. They are carnivores; although they have been considered as eating mostly carrion, they will frequently ambush live prey with a stealthy approach. When suitable prey arrives near a dragon's ambush site, it will suddenly charge at the animal at high speeds and go for the underside or the throat.Komodo dragons do not deliberately allow the prey to escape with fatal injuries but try to kill prey outright using a combination of lacerating damage and blood loss. They have been recorded as killing wild pigs within seconds, and observations of Komodo dragons tracking prey for long distances are likely misinterpreted cases of prey escaping an attack before succumbing to infection.
+Komodo dragons eat by tearing large chunks of flesh and swallowing them whole while holding the carcass down with their forelegs. For smaller prey up to the size of a goat, their loosely articulated jaws, flexible skulls, and expandable stomachs allow them to swallow prey whole. The undigested vegetable contents of a prey animal's stomach and intestines are typically avoided. Copious amounts of red saliva the Komodo dragons produce help to lubricate the food, but swallowing is still a long process (15–20 minutes to swallow a goat). A Komodo dragon may attempt to speed up the process by ramming the carcass against a tree to force it down its throat, sometimes ramming so forcefully that the tree is knocked down. A small tube under the tongue that connects to the lungs allows it to breathe while swallowing.After eating up to 80% of its body weight in one meal, it drags itself to a sunny location to speed digestion, as the food could rot and poison the dragon if left undigested in its stomach for too long. Because of their slow metabolism, large dragons can survive on as few as 12 meals a year. After digestion, the Komodo dragon regurgitates a mass of horns, hair, and teeth known as the gastric pellet, which is covered in malodorous mucus. After regurgitating the gastric pellet, it rubs its face in the dirt or on bushes to get rid of the mucus.
+
+The eating habits of Komodo dragons follow a hierarchy, with the larger animals generally eating before the smaller ones. The largest male typically asserts his dominance and the smaller males show their submission by use of body language and rumbling hisses. Dragons of equal size may resort to "wrestling". Losers usually retreat, though they have been known to be killed and eaten by victors.The Komodo dragon's diet is wide-ranging, and includes invertebrates, other reptiles (including smaller Komodo dragons), birds, bird eggs, small mammals, monkeys, wild boar, goats, pigs, deer, horses, and water buffalo. Young Komodos will eat insects, eggs, geckos, and small mammals, while adults prefer to hunt large mammals. Occasionally, they attack and bite humans. Sometimes they consume human corpses, digging up bodies from shallow graves. This habit of raiding graves caused the villagers of Komodo to move their graves from sandy to clay ground, and pile rocks on top of them, to deter the lizards. The Komodo dragon may have evolved to feed on the extinct dwarf elephant Stegodon that once lived on Flores, according to evolutionary biologist Jared Diamond.The Komodo dragon drinks by sucking water into its mouth via buccal pumping (a process also used for respiration), lifting its head, and letting the water run down its throat.
+
+
+=== Saliva ===
+Although previous studies proposed that Komodo dragon saliva contains a variety of highly septic bacteria that would help to bring down prey, research in 2013 suggested that the bacteria in the mouths of Komodo dragons are ordinary and similar to those found in other carnivores. Komodo dragons have good mouth hygiene. To quote Bryan Fry: "After they are done feeding, they will spend 10 to 15 minutes lip-licking and rubbing their head in the leaves to clean their mouth ... Unlike people have been led to believe, they do not have chunks of rotting flesh from their meals on their teeth, cultivating bacteria." Nor do Komodo dragons wait for prey to die and track it at a distance, as vipers do; observations of them hunting deer, boar and in some cases buffalo reveal that they kill prey in less than half an hour.The observation of prey dying of sepsis would then be explained by the natural instinct of water buffalos, who are not native to the islands where the Komodo dragon lives, to run into water after escaping an attack. The warm, faeces-filled water would then cause the infections. The study used samples from 16 captive dragons (10 adults and six neonates) from three US zoos.
+
+
+=== Antibacterial immune factor ===
+Researchers have isolated a powerful antibacterial peptide from the blood plasma of Komodo dragons, VK25. Based on their analysis of this peptide, they have synthesized a short peptide dubbed DRGN-1 and tested it against multidrug-resistant (MDR) pathogens. Preliminary results of these tests show that DRGN-1 is effective in killing drug-resistant bacterial strains and even some fungi. It has the added observed benefit of significantly promoting wound healing in both uninfected and mixed biofilm infected wounds.
+
+
+=== Venom ===
+
+In late 2005, researchers at the University of Melbourne speculated the perentie (Varanus giganteus), other species of monitors, and agamids may be somewhat venomous. The team believes the immediate effects of bites from these lizards were caused by mild envenomation. Bites on human digits by a lace monitor (V. varius), a Komodo dragon, and a spotted tree monitor (V. scalaris) all produced similar effects: rapid swelling, localised disruption of blood clotting, and shooting pain up to the elbow, with some symptoms lasting for several hours.In 2009, the same researchers published further evidence demonstrating Komodo dragons possess a venomous bite. MRI scans of a preserved skull showed the presence of two glands in the lower jaw. The researchers extracted one of these glands from the head of a terminally ill dragon in the Singapore Zoological Gardens, and found it secreted several different toxic proteins. The known functions of these proteins include inhibition of blood clotting, lowering of blood pressure, muscle paralysis, and the induction of hypothermia, leading to shock and loss of consciousness in envenomated prey. As a result of the discovery, the previous theory that bacteria were responsible for the deaths of Komodo victims was disputed.Other scientists have stated that this allegation of venom glands "has had the effect of underestimating the variety of complex roles played by oral secretions in the biology of reptiles, produced a very narrow view of oral secretions and resulted in misinterpretation of reptilian evolution." According to these scientists "reptilian oral secretions contribute to many biological roles other than to quickly dispatch prey." These researchers concluded that, "Calling all in this clade venomous implies an overall potential danger that does not exist, misleads in the assessment of medical risks, and confuses the biological assessment of squamate biochemical systems." Evolutionary biologist Schwenk says that even if the lizards have venom-like proteins in their mouths they may be using them for a different function, and he doubts venom is necessary to explain the effect of a Komodo dragon bite, arguing that shock and blood loss are the primary factors.
+
+
+=== Reproduction ===
+
+Mating occurs between May and August, with the eggs laid in September. During this period, males fight over females and territory by grappling with one another upon their hind legs, with the loser eventually being pinned to the ground. These males may vomit or defecate when preparing for the fight. The winner of the fight will then flick his long tongue at the female to gain information about her receptivity. Females are antagonistic and resist with their claws and teeth during the early phases of courtship. Therefore, the male must fully restrain the female during coitus to avoid being hurt. Other courtship displays include males rubbing their chins on the female, hard scratches to the back, and licking. Copulation occurs when the male inserts one of his hemipenes into the female's cloaca. Komodo dragons may be monogamous and form "pair bonds", a rare behavior for lizards.Female Komodos lay their eggs from August to September and may use several types of locality; in one study, 60% laid their eggs in the nests of orange-footed scrubfowl (a moundbuilder or megapode), 20% on ground level and 20% in hilly areas. The females make many camouflage nests/holes to prevent other dragons from eating the eggs. Clutches contain an average of 20 eggs, which have an incubation period of 7–8 months. Hatching is an exhausting effort for the neonates, which break out of their eggshells with an egg tooth that falls off before long. After cutting themselves out, the hatchlings may lie in their eggshells for hours before starting to dig out of the nest. They are born quite defenseless and are vulnerable to predation. Sixteen youngsters from a single nest were on average 46.5 cm long and weighed 105.1 grams.Young Komodo dragons spend much of their first few years in trees, where they are relatively safe from predators, including cannibalistic adults, as juvenile dragons make up 10% of their diets. The habit of cannibalism may be advantageous in sustaining the large size of adults, as medium-sized prey on the islands is rare. When the young approach a kill, they roll around in faecal matter and rest in the intestines of eviscerated animals to deter these hungry adults. Komodo dragons take approximately 8 to 9 years to mature, and may live for up to 30 years.
+
+
+==== Parthenogenesis ====
+
+A Komodo dragon at London Zoo named Sungai laid a clutch of eggs in late 2005 after being separated from male company for more than two years. Scientists initially assumed she had been able to store sperm from her earlier encounter with a male, an adaptation known as superfecundation. On 20 December 2006, it was reported that Flora, a captive Komodo dragon living in the Chester Zoo in England, was the second known Komodo dragon to have laid unfertilised eggs: she laid 11 eggs, and seven of them hatched, all of them male. Scientists at Liverpool University in England performed genetic tests on three eggs that collapsed after being moved to an incubator, and verified Flora had never been in physical contact with a male dragon. After Flora's eggs' condition had been discovered, testing showed Sungai's eggs were also produced without outside fertilization. On 31 January 2008, the Sedgwick County Zoo in Wichita, Kansas, became the first zoo in the Americas to document parthenogenesis in Komodo dragons. The zoo has two adult female Komodo dragons, one of which laid about 17 eggs on 19–20 May 2007. Only two eggs were incubated and hatched due to space issues; the first hatched on 31 January 2008, while the second hatched on 1 February. Both hatchlings were males.Komodo dragons have the ZW chromosomal sex-determination system, as opposed to the mammalian XY system. Male progeny prove Flora's unfertilized eggs were haploid (n) and doubled their chromosomes later to become diploid (2n) (by being fertilized by a polar body, or by chromosome duplication without cell division), rather than by her laying diploid eggs by one of the meiosis reduction-divisions in her ovaries failing. When a female Komodo dragon (with ZW sex chromosomes) reproduces in this manner, she provides her progeny with only one chromosome from each of her pairs of chromosomes, including only one of her two sex chromosomes. This single set of chromosomes is duplicated in the egg, which develops parthenogenetically. Eggs receiving a Z chromosome become ZZ (male); those receiving a W chromosome become WW and fail to develop, meaning that only males are produced by parthenogenesis in this species.
+It has been hypothesised that this reproductive adaptation allows a single female to enter an isolated ecological niche (such as an island) and by parthenogenesis produce male offspring, thereby establishing a sexually reproducing population (via reproduction with her offspring that can result in both male and female young). Despite the advantages of such an adaptation, zoos are cautioned that parthenogenesis may be detrimental to genetic diversity.
+
+
+=== Encounters with humans ===
+
+Attacks on humans are rare, but Komodo dragons have been responsible for several human fatalities, in both the wild and in captivity. According to data from Komodo National Park spanning a 38-year period between 1974 and 2012, there were 24 reported attacks on humans, five of them fatal. Most of the victims were local villagers living around the national park.
+
+
+== Conservation ==
+
+The Komodo dragon is classified by the IUCN as Endangered and is listed on the IUCN Red List. The species' sensitivity to natural and man-made threats has long been recognized by conservationists, zoological societies, and the Indonesian government. Komodo National Park was founded in 1980 to protect Komodo dragon populations on islands including Komodo, Rinca, and Padar. Later, the Wae Wuul and Wolo Tado Reserves were opened on Flores to aid Komodo dragon conservation.Komodo dragons generally avoid encounters with humans. Juveniles are very shy and will flee quickly into a hideout if a human comes closer than about 100 metres (330 ft). Older animals will also retreat from humans from a shorter distance away. If cornered, they may react aggressively by gaping their mouth, hissing, and swinging their tail. If they are disturbed further, they may attack and bite. Although there are anecdotes of unprovoked Komodo dragons attacking or preying on humans, most of these reports are either not reputable or have subsequently been interpreted as defensive bites. Only very few cases are truly the result of unprovoked attacks by atypical individuals who lost their fear of humans.Volcanic activity, earthquakes, loss of habitat, fire, tourism, loss of prey due to poaching, and illegal poaching of the dragons themselves have all contributed to the vulnerable status of the Komodo dragon. A major future threat to the species is climate change via both aridification and sea level rise, which can affect the low-lying habitats and valleys that the Komodo dragon depends on, as Komodo dragons do not range into the higher-altitude regions of the islands they inhabit. Based on projections, climate change will lead to a decline in suitable habitat of 8.4%, 30.2%, or 71% by 2050 depending on the climate change scenario. Without effective conservation actions, populations on Flores are extirpated in all scenarios, while in the more extreme scenarios, only the populations on Komodo and Rinca persist in highly reduced numbers. Rapid climate change mitigation is crucial for conserving the species in the wild. Other scientists have disputed the conclusions about the effects of climate change on Komodo dragon populations.Under Appendix I of CITES (the Convention on International Trade in Endangered Species), commercial international trade of Komodo dragon skins or specimens is prohibited. Despite this, there are occasional reports of illegal attempts to trade in live Komodo dragons. The most recent attempt was in March 2019, when Indonesian police in the East Java city of Surabaya reported that a criminal network had been caught trying to smuggle 41 young Komodo dragons out of Indonesia. The plan was said to include shipping the animals to several other countries in Southeast Asia through Singapore. It was hoped that the animals could be sold for up to 500 million rupiah (around US$35,000) each. It was believed that the Komodo dragons had been smuggled out of East Nusa Tenggara province through the port at Ende in central Flores.In 2013, the total population of Komodo dragons in the wild was assessed as 3,222 individuals, declining to 3,092 in 2014 and 3,014 in 2015. Populations remained relatively stable on the bigger islands (Komodo and Rinca), but decreased on smaller islands, such as Nusa Kode and Gili Motang, likely due to diminishing prey availability. On Padar, a former population of Komodo dragons has recently become extinct, of which the last individuals were seen in 1975. It is widely assumed that the Komodo dragon died out on Padar following a major decline of populations of large ungulate prey, for which poaching was most likely responsible.
+
+
+=== In captivity ===
+
+Komodo dragons have long been sought-after zoo attractions, where their size and reputation make them popular exhibits. They are, however, rare in zoos because they are susceptible to infection and parasitic disease if captured from the wild, and do not readily reproduce in captivity. The first Komodo dragons were displayed at London Zoo in 1927. A Komodo dragon was exhibited in 1934 in the United States at the National Zoo in Washington, D.C., but it lived for only two years. More attempts to exhibit Komodo dragons were made, but the lifespan of the animals proved very short, averaging five years in the National Zoological Park. Studies were done by Walter Auffenberg, which were documented in his book The Behavioral Ecology of the Komodo Monitor, eventually allowed for more successful management and breeding of the dragons in captivity. As of May 2009, there were 35 North American, 13 European, one Singaporean, two African, and two Australian institutions which housed captive Komodo dragons.A variety of behaviors have been observed from captive specimens. Most individuals become relatively tame within a short time, and are capable of recognising individual humans and discriminating between familiar and unfamiliar keepers. Komodo dragons have also been observed to engage in play with a variety of objects, including shovels, cans, plastic rings, and shoes. This behavior does not seem to be "food-motivated predatory behavior".Even seemingly docile dragons may become unpredictably aggressive, especially when the animal's territory is invaded by someone unfamiliar. In June 2001, a Komodo dragon seriously injured Phil Bronstein, the then-husband of actress Sharon Stone, when he entered its enclosure at the Los Angeles Zoo after being invited in by its keeper. Bronstein was bitten on his bare foot, as the keeper had told him to take off his white shoes and socks, which the keeper stated could potentially excite the Komodo dragon as they were the same colour as the white rats the zoo fed the dragon. Although he survived, Bronstein needed to have several tendons in his foot reattached surgically.

+The black-and-white ruffed lemur (Varecia variegata) is an endangered species of ruffed lemur, one of two which are endemic to the island of Madagascar. Despite having a larger range than the red ruffed lemur, it has a much smaller population that is spread out, living in lower population densities and reproductively isolated. It also has less coverage and protection in large national parks than the red ruffed lemur. Three subspecies of black-and-white ruffed lemur have been recognized since the red ruffed lemur was elevated to species status in 2001.Together with the red ruffed lemur, they are the largest extant members of the family Lemuridae, ranging in length from 100 to 120 cm (3.3 to 3.9 ft) and weighing between 3.1 and 4.1 kg (6.8 and 9.0 lb). They are arboreal, spending most of their time in the high canopy of the seasonal rainforests on the eastern side of the island.  They are also diurnal, active exclusively in daylight hours. Quadrupedal locomotion is preferred in the trees and on the ground, and suspensory behavior is seen during feeding.  As the most frugivorous of lemurs, the diet consists mainly of fruit, although nectar and flowers are also favored, followed by leaves and some seeds.The black-and-white ruffed lemur has a complex social structure and is known for its loud, raucous calls. It is unusual in that it exhibits several reproductive traits typically found in small, nocturnal lemurs, such as a short gestation period, large litters and rapid maturation. In captivity, they can live up to 36 years.
+
+
+== Taxonomy ==
+The black-and-white ruffed lemur is one of two species in the genus Varecia, the other being the red ruffed lemur (V. rubra). Three subspecies are recognized: the white-belted black-and-white ruffed lemur (V. v. subcincta), the Hill's ruffed lemur, (V. v. editorum), and the black-and-white ruffed lemur (V. v. variegata, the nominate subspecies).

+Together with the red ruffed lemur, the species is the largest extant member of the family Lemuridae, ranging in length from 100 to 120 cm (3.3 to 3.9 ft) and weighing between 3.1 and 4.1 kg (6.8 and 9.0 lb).
+The black-and-white ruffed lemur is always both black and white; the general color patterns do not usually vary. Abdomen, tail, hands and feet, inner limbs, forehead, face and crown are black. The fur is white on the sides, back, hind limbs and on the hindquarters. Males and females are alike.
+
+
+== Distribution and habitat ==
+The species inhabits the eastern rainforests of Madagascar. It occurs at low to moderate altitudes, in primary forests with tall and mature trees, and by preference deep inside contiguous blocks of vegetation, although patchy forests are made use of if necessary.The three subspecies have slightly different ranges. The white-belted black-and-white ruffed lemur is found furthest to the north, the southern black-and-white ruffed lemur is found furthest to the south, and the black-and-white ruffed lemur has a geographic range between the other two subspecies.
+
+
+== Diet ==
+Wild black-and-white ruffed lemurs have a highly frugivorous diet, with fruit making up 92% of their overall diet. Smaller percentages of leaves, nectar, seeds, and even fungi make up the remainder. Their diet is also influenced by the seasons, with certain plant parts and fruits only ripening or becoming available during certain times of the year. Water consumption also varies throughout the year and can be influenced by diet. The number of tree species utilized by for food by the lemurs can range from 19 to 40 species depending on location. The larger part of fruit items in the diet is provided by four taxa of fruit trees: Ravensara species, Chrysophyllum boivinianum, Protorhus species, and Harungana madagascariensis.
+
+
+== Behavior ==
+
+
+=== Female dominance ===
+Black-and-white ruffed lemurs demonstrate the rare behavior of female social dominance both within and outside the context of feedings. This is also found in other ruffed lemurs as well as in ring-tailed lemurs and red ruffed lemurs. Aggressive interactions between males and females are usually won by the female even when they do not show aggressive behavior towards the male. Unlike other species of lemurs, black-and-white ruffed lemur females occasionally show submission and more aggression needs to be maintained in order for the female to win the interaction instead of having an undecided interaction. Male aggression does not vary among seasons.One of the main reasons that black-and-white ruffed lemurs exhibit dominance is for feeding purpose; that is they are able to establish priority over males in feeding. Reproductive females need more access to food because of the costs of carrying and caring for offspring which is why they establish this feeding priority. Energy demands in this species are particularly high. Female dominance in feeding is maintained through demonstrating some aggressive behavior and leading the group to food in order to have first access to the food. Dominance is not thought to be established in younger females so groups lacking a mature female may not have a dominant female. When a dominant female is present, she leads the group to the food source and eats more than the rest of the group.
+
+
+=== Communication ===
+The black-and-white ruffed lemur demonstrates several different call types each of which last several seconds. Most lemurs of a group participate in any one chorus. These lemurs are particularly known for their loud roar/shriek choruses which have several purposes including group movement, spacing among different groups, and alarming other members of the group of predators. Unlike the calls of other species, the calls of the black-and-white ruffed lemur are not likely to be for the establishment of territory for a group. The calling behavior is participated in throughout the course of a day, not concentrated at any one point of the day; however calls are usually not heard at night.
+
+
+=== Interspecific interactions ===
+Black-and-white ruffed lemurs are known to form a natural hybrid zone with the red ruffed lemur. This zone may have once been very large before humans came into contact with the two subspecies.  The calls of the two organisms differ in frequency and pulse rate.
+
+
+=== Social structure ===
+Studies of groups of black-and-white ruffed lemurs both in captivity and in the wild have demonstrated a variety of social structures from pairs to large groups. Groups have been shown to exhibit a range of fission fusion dynamics, meaning that group size can fluctuate based on resource availability. When resources (e.g. food) are plentiful, the environment can support a larger group of lemurs, but when resources are scarce, the group may split into smaller sub-groups to survive. The sub-groups can rejoin and split as needed with environmental and social cues. Parenting in this species of lemurs is unique in that no single infant is invested in but instead, females bear litters of multiple offspring. Males also play a role in the parenting of the offspring especially in smaller groups where the certainty of paternity is high. In larger groups, the chance of a female mating with more than one male increases as does uncertainty in paternity. This tends to decrease the level of male care of offspring. Instead of clinging to the mother, offspring are placed into a nest which is guarded by both parents, described in detail below.
+
+
+=== Reproduction ===
+Both males and females reach sexual maturity between the ages of 1.5 and 3 years, although breeding is not necessarily successful during the first year of maturity. Males exhibit testicular enlargement as they mature, which gradually increases over the months leading to their breeding window. After successfully breeding with a female, the male's testicles gradually reduce to normal. When females become sexually mature and enter estrus during the breeding season, their vaginas begin to open slightly, starting with a small pink dot and line, which is easily visible because the skin around the vulva is black. The pink area gradually opens over the course of several days. Once fully opened, vaginal estrus lasts 2–3 days. During this time, there is an even smaller window of time (6–12 hours) when the female is in behavioral estrus, and breeding is only possible during this period. After breeding, the female's vulva gradually closes and remains black and closed for the remainder of the year. Gestation lasts an average of 102.5 days and typically results in a litter of 2–6 offspring that are unable to cling to their mother, as in other primates. The female builds a nest where infants remain until they can leave it on their own. For the first two weeks after birth, the female stays with the infants nearly 24 hours a day. Both males and females will guard the nest. There is evidence that related as well as unrelated females will deposit their infants in communal nests and share in parental care while other individuals forage, resulting in increased infant survival compared to single-nesting females.
+
+
+== Conservation ==
+All three subspecies of the black-and-white ruffed lemur are classified as Critically Endangered by the IUCN. The numbers of black-and-white ruffed lemurs are on a steep downward trend, dropping 80% in the 21 years before 2020, the equivalent to three generations. The Vasey studies in 2003 indicated that Nosy Mangabe is the most densely populated area of black and white ruffed lemurs. It had around 29–43 individuals/km2. Next in decreasing order came Anatanamatazo with 10–15 individuals/km2, and then Manomba with.4-2.5 individuals/km2.
+
+
+=== Threats in the wild ===
+While predators may be a large threat to the black and white ruffed lemur, the principal threat to their survival comes from the human inhabitants of the island. Since they are comparatively large to other species of lemurs they are hunted as bushmeat by poachers and village men who are looking to feed their families. Another threat to the lemurs is the agricultural practices of the local community. The slash-and-burn method of agriculture is very devastating to the natural habitat of the black and white ruffed lemur.The black-and-white ruffed lemur is preyed upon by the Henst's goshawk (Accipiter henstii), fossa (Cryptoprocta ferox), ring-tailed mongoose (Galidia elegans) and brown-tailed mongoose (Salanoia concolor).  Nesting behavior poses the greatest risks for predation, especially mammalian predators.
+
+
+=== Reintroduction ===
+Black-and-white ruffed lemurs were part of a reintroduction program from 1997 to 2001, organized by the Madagascar Fauna Group and the Duke University Primate Center (now Duke Lemur Center). A total of 13 individuals that were born in human care in the United States were released at the Betampona Reserve, which is in their native range in the rainforests of eastern Madagascar. Prior to being released, individuals were selected by the ruffed lemur Species Survival Plan based on genetic information, health status, life history, and behavioral traits.All of the individuals underwent a "boot camp" program prior to release that gave the lemurs experience in a free-range naturally wooded environment. During this time, the lemurs were able to improve their physical abilities in a forest canopy as well as forage for naturally growing food. The lemurs were released in 3 groups, each consisting of a family group or pairing, to mimic their natural grouping patterns.Once released into the wild, the animals each had radio transmitting collars, to aid in the research and monitoring possibilities post-release. The lemurs were provided with some supplementary food and their health and behavior was monitored. At least 5 of the released individuals were killed by fossa, a native predator of lemurs, including a breeding pair that had previously raised triplets. Of the surviving lemurs, at least 1 male successfully merged with an existing wild group and reproduced. Future reintroduction efforts are halted due to habitat degradation and fragmentation.

+The black-and-white ruffed lemur (Varecia variegata) is an endangered species of ruffed lemur, one of two which are endemic to the island of Madagascar. Despite having a larger range than the red ruffed lemur, it has a much smaller population that is spread out, living in lower population densities and reproductively isolated. It also has less coverage and protection in large national parks than the red ruffed lemur. Three subspecies of black-and-white ruffed lemur have been recognized since the red ruffed lemur was elevated to species status in 2001.Together with the red ruffed lemur, they are the largest extant members of the family Lemuridae, ranging in length from 100 to 120 cm (3.3 to 3.9 ft) and weighing between 3.1 and 4.1 kg (6.8 and 9.0 lb). They are arboreal, spending most of their time in the high canopy of the seasonal rainforests on the eastern side of the island.  They are also diurnal, active exclusively in daylight hours. Quadrupedal locomotion is preferred in the trees and on the ground, and suspensory behavior is seen during feeding.  As the most frugivorous of lemurs, the diet consists mainly of fruit, although nectar and flowers are also favored, followed by leaves and some seeds.The black-and-white ruffed lemur has a complex social structure and is known for its loud, raucous calls. It is unusual in that it exhibits several reproductive traits typically found in small, nocturnal lemurs, such as a short gestation period, large litters and rapid maturation. In captivity, they can live up to 36 years.
+
+
+== Taxonomy ==
+The black-and-white ruffed lemur is one of two species in the genus Varecia, the other being the red ruffed lemur (V. rubra). Three subspecies are recognized: the white-belted black-and-white ruffed lemur (V. v. subcincta), the Hill's ruffed lemur, (V. v. editorum), and the black-and-white ruffed lemur (V. v. variegata, the nominate subspecies).

+A well is an excavation or structure created in the ground by digging, driving, or drilling to access liquid resources, usually water. The oldest and most common kind of well is a water well, to access groundwater in underground aquifers. The well water is drawn up by a pump, or using containers, such as buckets or large water bags that are raised mechanically or by hand. Water can also be injected back into the aquifer through the well. Wells were first constructed at least eight thousand years ago and historically vary in construction from a simple scoop in the sediment of a dry watercourse to the qanats of Iran, and the stepwells and sakiehs of India. Placing a lining in the well shaft helps create stability, and linings of wood or wickerwork date back at least as far as the Iron Age.
+Wells have traditionally been sunk by hand digging, as is still the case in rural areas of the developing world. These wells are inexpensive and low-tech as they use mostly manual labour, and the structure can be lined with brick or stone as the excavation proceeds. A more modern method called caissoning uses pre-cast reinforced concrete well rings that are lowered into the hole. Driven wells can be created in unconsolidated material with a well hole structure, which consists of a hardened drive point and a screen of perforated pipe, after which a pump is installed to collect the water. Deeper wells can be excavated by hand drilling methods or machine drilling, using a bit in a borehole. Drilled wells are usually cased with a factory-made pipe composed of steel or plastic. Drilled wells can access water at much greater depths than dug wells.
+Two broad classes of well are shallow or unconfined wells completed within the uppermost saturated aquifer at that location, and deep or confined wells, sunk through an impermeable stratum into an aquifer beneath. A collector well can be constructed adjacent to a freshwater lake or stream with water percolating through the intervening material. The site of a well can be selected by a hydrogeologist, or groundwater surveyor. Water may be pumped or hand drawn. Impurities from the surface can easily reach shallow sources and contamination of the supply by pathogens or chemical contaminants needs to be avoided. Well water typically contains more minerals in solution than surface water and may require treatment before being potable. Soil salination can occur as the water table falls and the surrounding soil begins to dry out. Another environmental problem is the potential for methane to seep into the water.
+
+
+== History ==
+
+Very early neolithic wells are known from the Eastern Mediterranean: The oldest reliably dated well is from the pre-pottery neolithic (PPN) site of Kissonerga-Mylouthkia on Cyprus. At around 8400 BC a shaft (well 116) of circular diameter was driven through limestone to reach an aquifer at a depth of 8 metres (26 ft). Well 2070 from Kissonerga-Mylouthkia, dating to the late PPN, reaches a depth of 13 metres (43 ft). Other slightly younger wells are known from this site and from neighbouring Parekklisha-Shillourokambos. A first stone lined well of 5.5 metres (18 ft) depth is documented from a drowned final PPN (c. 7000 BC) site at ‘Atlit-Yam off the coast near modern Haifa in Israel. 
+Wood-lined wells are known from the early Neolithic Linear Pottery culture, for example in Ostrov, Czech Republic, dated 5265 BC, Kückhoven (an outlying centre of Erkelenz), dated 5090 BC, and Eythra in Schletz (an outlying centre of Asparn an der Zaya) in Austria, dated 5200 BC.Some of the earliest evidence of water wells is located in China. The neolithic Chinese discovered and made extensive use of deep drilled groundwater for drinking. The Chinese text The Book of Changes, originally a divination text of the Western Zhou dynasty (1046 -771 BC), contains an entry describing how the ancient Chinese maintained their wells and protected their sources of water. A well excavated at the Hemedu excavation site was believed to have been built during the neolithic era. The well was cased by four rows of logs with a square frame attached to them at the top of the well. 60 additional tile wells southwest of Beijing are also believed to have been built around 600 BC for drinking and irrigation.
+
+In Egypt, shadoofs and sakias are used. The sakia is much more efficient, as it can bring up water from a depth of 10 metres (versus the 3 metres of the shadoof). The sakia is the Egyptian version of the noria. Some of the world's oldest known wells, located in Cyprus, date to 7000–8,500 BC. Two wells from the Neolithic period, around 6500 BC, have been discovered in Israel. One is in Atlit, on the northern coast of Israel, and the other is the Jezreel Valley.Wells for other purposes came along much later, historically. The first recorded salt well was dug in the Sichuan province of China around 2,250 years ago. This was the first time that ancient water well technology was applied successfully for the exploitation of salt, and marked the beginning of Sichuan's salt drilling industry. The earliest known oil wells were also drilled in China, in 347 CE. These wells had depths of up to about 240 metres (790 ft) and were drilled using bits attached to bamboo poles. The oil was burned to evaporate brine and produce salt. By the 10th century, extensive bamboo pipelines connected oil wells with salt springs. The ancient records of China and Japan are said to contain many allusions to the use of natural gas for lighting and heating. Petroleum was known as Burning water in Japan in the 7th century.
+
+
+== Types ==
+
+
+=== Dug wells ===
+
+Until recent centuries, all artificial wells were pumpless hand-dug wells of varying degrees of sophistication, and they remain a very important source of potable water in some rural developing areas, where they are routinely dug and used today. Their indispensability has produced a number of literary references, literal and figurative, including the reference to the incident of Jesus meeting a woman at Jacob's well (John 4:6) in the Bible and the "Ding Dong Bell" nursery rhyme about a cat in a well.
+Hand-dug wells are excavations with diameters large enough to accommodate one or more people with shovels digging down to below the water table. The excavation is braced horizontally to avoid landslide or erosion endangering the people digging. They can be lined with stone or brick; extending this lining upwards above the ground surface to form a wall around the well serves to reduce both contamination and accidental falls into the well. 
+A more modern method called caissoning uses reinforced concrete or plain concrete pre-cast well rings that are lowered into the hole. A well-digging team digs under a cutting ring and the well column slowly sinks into the aquifer, whilst protecting the team from collapse of the well bore.
+Hand-dug wells are inexpensive and low tech (compared to drilling) and they use mostly manual labour to access groundwater in rural locations of developing countries.  They may be built with a high degree of community participation, or by local entrepreneurs who specialize in hand-dug wells. They have been successfully excavated to 60 metres (200 ft). They have low operational and maintenance costs, in part because water can be extracted by hand, without a pump. The water often comes from an aquifer or groundwater, and can be easily deepened, which may be necessary if the ground water level drops, by telescoping the lining further down into the aquifer. The yield of existing hand dug wells may be improved by deepening or introducing vertical tunnels or perforated pipes.
+Drawbacks to hand-dug wells are numerous. It can be impractical to hand dig wells in areas where hard rock is present, and they can be time-consuming to dig and line even in favourable areas. Because they exploit shallow aquifers, the well may be susceptible to yield fluctuations and possible contamination from surface water, including sewage. Hand dug well construction generally requires the use of a well trained construction team, and the capital investment for equipment such as concrete ring moulds, heavy lifting equipment, well shaft formwork, motorized de-watering pumps, and fuel can be large for people in developing countries. Construction of hand dug wells can be dangerous due to collapse of the well bore, falling objects and asphyxiation, including from dewatering pump exhaust fumes.
+The Woodingdean Water Well, hand-dug between 1858 and 1862, is the deepest hand-dug well at 392 metres (1,285 ft). The Big Well in Greensburg, Kansas is billed as the world's largest hand-dug well, at 109 feet (33 m) deep and 32 feet (9.8 m) in diameter. However, the Well of Joseph in the Cairo Citadel at 280 feet (85 m) deep and the Pozzo di S. Patrizio (St. Patrick's Well) built in 1527 in Orvieto, Italy, at 61 metres (200 ft) deep by 13 metres (43 ft) wide are both larger by volume.
+
+
+=== Driven wells ===
+Driven wells may be very simply created in unconsolidated material with a well hole structure, which consists of a hardened drive point and a screen (perforated pipe). The point is simply hammered into the ground, usually with a tripod and driver, with pipe sections added as needed. A driver is a weighted pipe that slides over the pipe being driven and is repeatedly dropped on it. When groundwater is encountered, the well is washed of sediment and a pump installed.
+
+
+=== Drilled wells ===
+
+Drilled wells are typically created using either top-head rotary style, table rotary, or cable tool drilling machines, all of which use drilling stems that are turned to create a cutting action in the formation, hence the term drilling.
+Drilled wells can be excavated by simple hand drilling methods (augering, sludging, jetting, driving, hand percussion) or machine drilling (rotary, percussion, down the hole hammer). Deeprock rotary drilling method is most common. Rotary can be used in 90% of formation types.
+Drilled wells can get water from a much deeper level than dug wells can—often down to several hundred metres.Drilled wells with electric pumps are used throughout the world, typically in rural or sparsely populated areas, though many urban areas are supplied partly by municipal wells. Most shallow well drilling machines are mounted on large trucks, trailers, or tracked vehicle carriages. Water wells typically range from 3 to 18 metres (10–60 ft) deep, but in some areas can go deeper than 900 metres (3,000 ft).
+
+Rotary drilling machines use a segmented steel drilling string, typically made up of 6 m (20 ft) sections of galvanized steel tubing that are threaded together, with a bit or other drilling device at the bottom end.  Some rotary drilling machines are designed to install (by driving or drilling) a steel casing into the well in conjunction with the drilling of the actual bore hole. Air and/or water is used as a circulation fluid to displace cuttings and cool bits during the drilling. Another form of rotary-style drilling, termed mud rotary, makes use of a specially made mud, or drilling fluid, which is constantly being altered during the drill so that it can consistently create enough hydraulic pressure to hold the side walls of the bore hole open, regardless of the presence of a casing in the well. Typically, boreholes drilled into solid rock are not cased until after the drilling process is completed, regardless of the machinery used.
+The oldest form of drilling machinery is the cable tool, still used today. Specifically designed to raise and lower a bit into the bore hole, the spudding of the drill causes the bit to be raised and dropped onto the bottom of the hole, and the design of the cable causes the bit to twist at approximately 1⁄4 revolution per drop, thereby creating a drilling action. Unlike rotary drilling, cable tool drilling requires the drilling action to be stopped so that the bore hole can be bailed or emptied of drilled cuttings.
+Drilled wells are usually cased with a factory-made pipe, typically steel (in air rotary or cable tool drilling) or plastic/PVC (in mud rotary wells, also present in wells drilled into solid rock). The casing is constructed by welding, either chemically or thermally, segments of casing together. If the casing is installed during the drilling, most drills will drive the casing into the ground as the bore hole advances, while some newer machines will actually allow for the casing to be rotated and drilled into the formation in a similar manner as the bit advancing just below.  PVC or plastic is typically welded and then lowered into the drilled well, vertically stacked with their ends nested and either glued or splined together. The sections of casing are usually 6 metres (20 ft) or more in length, and 6 to 12 in (15 to 30 cm) in diameter, depending on the intended use of the well and local groundwater conditions.
+Surface contamination of wells in the United States is typically controlled by the use of a surface seal. A large hole is drilled to a predetermined depth or to a confining formation (clay or bedrock, for example), and then a smaller hole for the well is completed from that point forward. The well is typically cased from the surface down into the smaller hole with a casing that is the same diameter as that hole. The annular space between the large bore hole and the smaller casing is filled with bentonite clay, concrete, or other sealant material. This creates an impermeable seal from the surface to the next confining layer that keeps contaminants from traveling down the outer sidewalls of the casing or borehole and into the aquifer. In addition, wells are typically capped with either an engineered well cap or seal that vents air through a screen into the well, but keeps insects, small animals, and unauthorized persons from accessing the well.
+At the bottom of wells, based on formation, a screening device, filter pack, slotted casing, or open bore hole is left to allow the flow of water into the well. Constructed screens are typically used in unconsolidated formations (sands, gravels, etc.), allowing water and a percentage of the formation to pass through the screen. Allowing some material to pass through creates a large area filter out of the rest of the formation, as the amount of material present to pass into the well slowly decreases and is removed from the well. Rock wells are typically cased with a PVC liner/casing and screen or slotted casing at the bottom, this is mostly present just to keep rocks from entering the pump assembly. Some wells utilize a filter pack method, where an undersized screen or slotted casing is placed inside the well and a filter medium is packed around the screen, between the screen and the borehole or casing. This allows the water to be filtered of unwanted materials before entering the well and pumping zone.

+
+
+== Classification ==
+
+There are two broad classes of drilled-well types, based on the type of aquifer the well is in:
+
+Shallow or unconfined wells are completed in the uppermost saturated aquifer at that location (the upper unconfined aquifer).
+Deep or confined wells are sunk through an impermeable stratum into an aquifer that is sandwiched between two impermeable strata (aquitards or aquicludes).  The majority of deep aquifers are classified as artesian because the hydraulic head in a confined well is higher than the level of the top of the aquifer. If the hydraulic head in a confined well is higher than the land surface it is a "flowing" artesian well (named after Artois in France).
+A special type of water well may be constructed adjacent to freshwater lakes or streams. Commonly called a collector well but sometimes referred to by the trade name Ranney well or Ranney collector, this type of well involves sinking a caisson vertically below the top of the aquifer and then advancing lateral collectors out of the caisson and beneath the surface water body. Pumping from within the caisson induces infiltration of water from the surface water body into the aquifer, where it is collected by the collector well laterals and conveyed into the caisson where it can be pumped to the ground surface.Two additional broad classes of well types may be distinguished, based on the use of the well:
+
+production or pumping wells, are large diameter (greater than 15 cm in diameter) cased (metal, plastic, or concrete) water wells,  constructed for extracting water from the aquifer by a pump (if the well is not artesian).
+monitoring wells or piezometers, are often smaller diameter wells used to monitor the hydraulic head or sample the groundwater for chemical constituents. Piezometers are monitoring wells completed over a very short section of aquifer. Monitoring wells can also be completed at multiple levels, allowing discrete samples or measurements to be made at different vertical elevations at the same map location.A well constructed for pumping groundwater can be used passively as a monitoring well and a small diameter well can be pumped, but this distinction by use is common.
+
+
+== Siting ==
+Before excavation, information about the geology, water table depth, seasonal fluctuations, recharge area and rate must be found. This work is typically done by a hydrogeologist, or a groundwater surveyor using a variety of tools including electro-seismic surveying, any available information from nearby wells, geologic maps, and sometimes geophysical imaging.
+
+
+== Contamination ==
+
+Shallow pumping wells can often supply drinking water at a very low cost. However, impurities from the surface easily reach shallow sources, which leads to a greater risk of contamination for these wells compared to deeper wells. Contaminated wells can lead to the spread of various waterborne diseases. Dug and driven wells are relatively easy to contaminate; for instance, most dug wells are unreliable in the majority of the United States.
+
+
+=== Pathogens ===
+Most of the bacteria, viruses, parasites, and fungi that contaminate well water comes from fecal material from humans and other animals, for example from on-site sanitation systems (such as pit latrines and septic tanks). Common bacterial contaminants include E. coli, Salmonella, Shigella, and Campylobacter jejuni. Common viral contaminants include norovirus, sapovirus, rotavirus, enteroviruses, and hepatitis A and E. Parasites include Giardia lamblia, Cryptosporidium, Cyclospora cayetanensis, and microsporidia.
+
+
+=== Chemical contamination ===
+Chemical contamination is a common problem with groundwater. Nitrates from sewage, sewage sludge or fertilizer are a particular problem for babies and young children. Pollutant chemicals include pesticides and volatile organic compounds from gasoline, dry-cleaning, the fuel additive methyl tert-butyl ether (MTBE), and perchlorate from rocket fuel, airbag inflators, and other artificial and natural sources.Several minerals are also contaminants, including lead leached from brass fittings or old lead pipes, chromium VI from electroplating and other sources, naturally occurring arsenic, radon, and uranium—all of which can cause cancer—and naturally occurring fluoride, which is desirable in low quantities to prevent tooth decay, but can cause dental fluorosis in higher concentrations.Some chemicals are commonly present in water wells at levels that are not toxic, but can cause other problems. Calcium and magnesium cause what is known as hard water, which can precipitate and clog pipes or burn out water heaters. Iron and manganese can appear as dark flecks that stain clothing and plumbing, and can promote the growth of iron and manganese bacteria that can form slimy black colonies that clog pipes.
+
+
+=== Prevention ===
+
+The quality of the well water can be significantly increased by lining the well, sealing the well head, fitting a self-priming hand pump, constructing an apron, ensuring the area is kept clean and free from stagnant water and animals, moving sources of contamination (pit latrines, garbage pits, on-site sewer systems) and carrying out hygiene education. The well should be cleaned with 1% chlorine solution after construction and periodically every 6 months.Well holes should be covered to prevent loose debris, animals, animal excrement, and wind-blown foreign matter from falling into the hole and decomposing. The cover should be able to be in place at all times, including when drawing water from the well. A suspended roof over an open hole helps to some degree, but ideally the cover should be tight fitting and fully enclosing, with only a screened air vent.Minimum distances and soil percolation requirements between sewage disposal sites and water wells need to be observed. Rules regarding the design and installation of private and municipal septic systems take all these factors into account so that nearby drinking water sources are protected.
+Education of the general population in society also plays an important role in protecting drinking water.
+
+
+=== Mitigation ===
+Cleanup of contaminated groundwater tends to be very costly. Effective remediation of groundwater is generally very difficult. Contamination of groundwater from surface and subsurface sources can usually be dramatically reduced by correctly centering the casing during construction and filling the casing annulus with an appropriate sealing material. The sealing material (grout) should be placed from immediately above the production zone back to surface, because, in the absence of a correctly constructed casing seal, contaminated fluid can travel into the well through the casing annulus. Centering devices are important (usually one per length of casing or at maximum intervals of 9 m) to ensure that the grouted annular space is of even thickness.Upon the construction of a new test well, it is considered best practice to invest in a complete battery of chemical and biological tests on the well water in question.  Point-of-use treatment is available for individual properties and treatment plants are often constructed for municipal water supplies that suffer from contamination.  Most of these treatment methods involve the filtration of the contaminants of concern, and additional protection may be garnered by installing well-casing screens only at depths where contamination is not present.Wellwater for personal use is often filtered with reverse osmosis water processors; this process can remove very small particles.  A simple, effective way of killing microorganisms is to bring the water to a full boil for one to three minutes, depending on location. A household well contaminated by microorganisms can initially be treated by shock chlorination using bleach, generating concentrations hundreds of times greater than found in community water systems; however, this will not fix any structural problems that led to the contamination and generally requires some expertise and testing for effective application.After the filtration process, it is common to implement an ultraviolet (UV) system to kill pathogens in the water. UV light affects the DNA of the pathogen by UV-C photons breaking through the cell wall. UV disinfection has been gaining popularity in the past decades as it is a chemical-free method of water treatment.
+
+
+== Environmental problems ==
+A risk with the placement of water wells is soil salination which occurs when the water table of the soil begins to drop and salt begins to accumulate as the soil begins to dry out. Another environmental problem that is very prevalent in water well drilling is the potential for methane to seep through.
+
+
+=== Soil salination ===
+The potential for soil salination is a large risk when choosing the placement of water wells. Soil salination is caused when the water table of the soil drops over time and salt begins to accumulate. In turn, the increased amount of salt begins to dry the soil out. The increased level of salt in the soil can result in the degradation of soil and can be very harmful to vegetation.
+
+
+=== Methane ===
+Methane, an asphyxiant, is a chemical compound that is the main component of natural gas. When methane is introduced into a confined space, it displaces oxygen, reducing oxygen concentration to a level low enough to pose a threat to humans and other aerobic organisms but still high enough for a risk of spontaneous or externally caused explosion.  This potential for explosion is what poses such a danger in regards to the drilling and placement of water wells.Low levels of methane in drinking water are not considered toxic. When methane seeps into a water supply, it is commonly referred to as "methane migration". This can be caused by old natural gas wells near water well systems becoming abandoned and no longer monitored.Lately, however, the described wells/pumps are no longer very efficient and can be replaced by either handpumps or treadle pumps. Another alternative is the use of self-dug wells, electrical deep-well pumps (for higher depths). Appropriate technology organizations as Practical Action are now supplying information on how to build/set-up (DIY) handpumps and treadle pumps in practice.
+
+
+== Water security ==
+A study concluded that of ~39 million groundwater wells 6-20% are at high risk of running dry if local groundwater levels decline by less than five meters, or – as with many areas and possibly more than half of major aquifers – continue to decline.
+
+
+== Society and culture ==
+
+Springs and wells have had cultural significance since prehistoric times, leading to the foundation of towns such as Wells and Bath in Somerset.  Interest in health benefits led to the growth of spa towns including many with wells in their name, examples being Llandrindod Wells and Royal Tunbridge Wells.Eratosthenes is sometimes claimed to have used a well in his calculation of the Earth's circumference; however, this is just a simplification used in a shorter explanation of Cleomedes, since Eratosthenes had used a more elaborate and precise method.Many incidents in the Bible take place around wells, such as the finding of a wife for Isaac in Genesis and Jesus's talk with the Samaritan woman in the Gospels.
+
+
+== A simple model for water well recovery ==
+
+For a well with impermeable walls, the water in the well is resupplied from the bottom of the well. The rate at which water flows into the well will depend on the pressure difference between the ground water at the well bottom and the well water at the well bottom. The pressure of a column of water of height z will be equal to the weight of the water in the column divided by the cross-sectional area of the column, so the pressure of the ground water a distance zT below the top of the water table will be:
+
+  
+    
+      
+        
+          P
+          
+            g
+          
+        
+        =
+        ρ
+        
+        g
+        
+        
+          z
+          
+            T
+          
+        
+      
+    
+    {\displaystyle P_{g}=\rho \,g\,z_{T}}
+  where ρ is the mass density of the water and g is the acceleration due to gravity. When the water in the well is below the water table level, the pressure at the bottom of the well due to the water in the well will be less than Pg and water will be forced into the well. Referring to the diagram, if z is the distance from the bottom of the well to the well water level and zT is the distance from the bottom of the well to the top of the water table, the pressure difference will be:
+
+  
+    
+      
+        Δ
+        P
+        =
+        ρ
+        
+        g
+        
+        (
+        
+          z
+          
+            T
+          
+        
+        −
+        z
+        )
+      
+    
+    {\displaystyle \Delta P=\rho \,g\,(z_{T}-z)}
+  Applying Darcy's Law, the volume rate (F) at which water is forced into the well will be proportional to this pressure difference:
+
+  
+    
+      
+        Δ
+        P
+        =
+        R
+        
+        F
+      
+    
+    {\displaystyle \Delta P=R\,F}
+  where R is the resistance to the flow, which depends on the well cross section, the pressure gradient at the bottom of the well, and the characteristics of the substrate at the well bottom. (e.g., porosity). The volume flow rate into the well can be written as a function of the rate of change of the well water level:
+
+  
+    
+      
+        F
+        =
+        A
+        
+          
+            
+              d
+              z
+            
+            
+              d
+              t
+            
+          
+        
+      
+    
+    {\displaystyle F=A{\frac {dz}{dt}}}
+  Combining the above three equations yields a simple differential equation in z:
+
+  
+    
+      
+        R
+        A
+

+          
+        
+      
+    
+    {\displaystyle z=z_{T}-(z_{T}-z_{0})e^{-t/\tau }}
+  where z0 is the well water level at time t=0 and τ is the well time constant:
+
+  
+    
+      
+        τ
+        =
+

+          
+        
+      
+    
+    {\displaystyle \tau ={\frac {RA}{\rho g}}}
+  Note that if dz/dt for a depleted well can be measured, it will be equal to 
+  
+    
+      
+        
+          z
+

+        τ
+      
+    
+    {\displaystyle z_{T}/\tau }
+   and the time constant τ can be calculated. According to the above model, it will take an infinite amount of time for a well to fully recover, but if we consider a well that is 99% recovered to be "practically" recovered, the time for a well to practically recover from a level at z will be:

+        
+      
+    
+    {\displaystyle T_{r}=\tau \ln \left({\frac {1-z/z_{T}}{1-0.99}}\right)}
+  For a well that is fully depleted (z=0) it would take a time of about 4.6 τ to practically recover.
+The above model does not take into account the depletion of the aquifer due to the pumping which lowered the well water level (See aquifer test and groundwater flow equation). Also, practical wells may have impermeable walls only up to, but not including the bedrock, which will give a larger surface area for water to enter the well.
