How heavy is an adult golden jackal?
26176430#1
The European jackal is the largest of the golden jackals, with animals of both sexes measuring 120–125 cm (47–49 in) in total length and 10–13 kg (20–29 lb) in body weight. One adult male in North-Eastern Italy is recorded to have reached 14.9 kg (33 lb). The fur is coarse, and is generally brightly coloured with blackish tones on the back. The thighs, upper legs, ears and forehead are bright reddish chestnut. Jackals in Northern Dalmatia have broader than average skulls, which is thought to result from human induced isolation from other populations, thus resulting in a new morphotype.

The golden jackal is similar to the gray wolf but is distinguished by its smaller size, lighter weight, more elongated torso, less-prominent forehead, shorter legs and tail, and a muzzle that is narrower and more pointed. The legs are long in relation to its body, and the feet are slender with small pads. Males measure in body length and females . Males weigh and females weigh . The shoulder height is for both. In comparison, the smallest wolf is the Arabian wolf ("Canis lupus arabs"), which weighs on average .

Social interactions such as greetings, grooming, and group howling are common in jackals. Howling is more frequent between December and April when pair bonds are being formed and breeding occurs, which suggests howling has a role in the delineation of territory and for defense. Adult jackals howl standing and the young or subordinate jackals howl sitting. Jackals are easily induced to howl and a single howl may solicit replies from several jackals in the vicinity. Howling begins with 2–3 low-pitched calls that rise to high-pitched calls. The howl consists of a wail repeated 3–4 times on an ascending scale, followed by three short yelps. Jackals typically howl at dawn and in the evening, and sometimes at midday. Adults may howl to accompany the ringing of church bells, with their young responding to sirens or the whistles of steam engines and boats. Social canids such as golden jackals, wolves, and coyotes respond to human imitations of their howls. When there is a change in the weather, jackals will produce a long and continuous chorus. Dominant canids defend their territories against intruders with either a howl to warn them off, approach and confront them, or howl followed by an approach. Jackals, wolves and coyotes will always approach a source of howling. Golden jackals give a warning call that is very different from their normal howling when they detect the presence of large carnivores such as wolves and tigers.

Golden jackals exhibit flexible social organization depending on the availability of food. The breeding pair is the basic social unit, and they are sometimes accompanied by their current litter of pups. In India, their distributions are a single jackal, 31%, two jackals, 35%, three jackals, 14%, and more than three jackals, 20%. Family groups of up to 4–5 individuals have been recorded. Scent marking through urination and defecation is common around golden jackal den areas and on the trails they most often use. Scent marking is thought to assist in territorial defense. The hunting ranges of several jackals can overlap. Jackals can travel up to during a single night in search of either food or more suitable habitat. Non-breeding members of a pack may stay near a distant food source, such as a carcass, for up to several days before returning to their home range. Home range sizes can vary between , depending on the available food.

Results from two recent studies of mDNA from golden jackals indicate that the specimens from Africa are genetically closer to the gray wolf than are the specimens from Eurasia. In 2015 a major DNA study of golden jackals concluded that the six "C.aureus" subspecies found in Africa should be reclassified under the new species "C.anthus" (African golden wolf), reducing the number of golden jackal subspecies to seven. The phylogenetic tree generated from this study shows the golden jackal diverging from the wolf/coyote lineage 1.9million years ago and the African golden wolf diverging 1.3million years ago. The study found that the golden jackal and the African golden wolf shared a very similar skull and body morphology and that this had confused taxonomists into regarding these as one species. The study proposes that the very similar skull and body morphology is due to both species having originated from a larger common ancestor.

The golden jackal ("Canis aureus") is a wolf-like canid that is native to Southeast Europe, Southwest Asia, South Asia, and regions of Southeast Asia. Compared with the Arabian wolf, which is the smallest of the gray wolves ("Canis lupus"), the jackal is smaller and possesses shorter legs, a shorter tail, a more elongated torso, a less-prominent forehead, and a narrower and more pointed muzzle. The golden jackal's coat can vary in color from a pale creamy yellow in summer to a dark tawny beige in winter. It is listed as Least Concern on the IUCN Red List due to its widespread distribution and high density in areas with plenty of available food and optimum shelter.

The golden jackal often hunts alone, and sometimes in pairs, but rarely hunts in a pack. When hunting alone, it trots around an area and occasionally stops to sniff and listen. Once prey is located, the jackal conceals itself, quickly approaches its prey and then pounces on it. Single jackals hunt rodents, hares, and birds. They hunt rodents in grass by locating them with their hearing before leaping into the air and pouncing on them. In India, they can dig Indian gerbils out from their burrows, and they can hunt young, old, and infirm ungulates up to 4–5 times their body weight. Jackals search for hiding blackbuck calves throughout the day during the calving period. The peak times for their searches are the early morning and the late evening. When hunting in pairs or packs, jackals run parallel to their prey and overtake it in unison. When hunting aquatic rodents or birds, they will run along both sides of narrow rivers or streams and drive their prey from one jackal to another.

The jackal's fur is coarse and relatively short, with the base color golden, varying seasonally from a pale creamy yellow to a dark tawny. The fur on the back is composed of a mixture of black, brown, and white hairs, sometimes giving the appearance of the dark saddle like that seen on the black-backed jackal. The underparts are a light pale ginger to cream color. Individual specimens can be distinguished by their unique light markings on the throat and chest. The coats of jackals from high elevations tend to be more buff-colored than those of their lowland counterparts while those of jackals in rocky, mountainous areas may exhibit a grayer shade. The bushy tail has a tan to black tip. Melanism can cause a dark-colored coat in some golden jackals, a coloring once fairly common in Bengal. Unlike melanistic wolves and coyotes that received their dark pigmentation from interbreeding with domestic dogs, melanism in golden jackals probably stems from an independent mutation that could be an adaptive trait. What is possibly an albino specimen was photographed in southeastern Iran during 2012.

In Russia and the other nations of the former Soviet Union, golden jackals are considered furbearers of low quality because of their sparse, coarse, and monotonously colored fur. Jackal hairs have very little fur fiber; therefore, their pelts have a flat appearance. The jackals of Asia and the Middle East produce the coarsest pelts, though this can be remedied during the dressing process. Elburz in northern Iran produces the softest furs. Jackal skins are not graded to a fur standard, and are made into collars, women's coats, and fur coats. During the 1880s, 200 jackals were captured annually in Mervsk and in the Zakatal area of the Transcaucasus, with 300 jackals being captured there during 1896. In this same period, a total of 10,000 jackals were taken within Russia and their furs sent exclusively to the Nizhegorod fair. In the early 1930s there were 20,000–25,000 jackal skins tanned annually in the Soviet Union, but these could not be utilized within the country, and so the majority were exported to the United States. Commencing from 1949, they were all used within the Soviet Union.

The golden jackal is listed as Least Concern on the IUCN Red List due to its widespread distribution, with it being common throughout its range and with high densities in those areas where food and shelter are abundant. In Europe, golden jackals are not listed under the 1973 "Convention on International Trade in Endangered Species of Wild Fauna and Flora" nor the 1979 Convention on the Conservation of Migratory Species of Wild Animals. Golden jackals in Europe fall under various international legal instruments. These include the 1979 "Berne Convention on the Conservation of European Wildlife and Natural Habitats", the "1992 Convention on Biological Diversity", and the 1992 European Union "Council Directive 92/43/EEC on the Conservation of Natural Habitats and of Wild Fauna and Flora". The Council Directive provides both guidance and limits on what participating governments can do when responding to the arrival of expanding jackals. These legislative instruments aim to contribute to conserving native wildlife; some governments argue that the golden jackal is not native wildlife but an invading species. The Golden Jackal informal study Group in Europe (GOJAGE) is an organization that is formed by researchers from across Europe to collect and share information on the golden jackal in Europe. The group also has an interest in the golden jackal's relationship with its environment across Eurasia. Membership is open to anyone who has an interest in golden jackals.

Golden jackals are abundant in valleys and beside rivers and their tributaries, canals, lakes, and seashores. They are rare in foothills and low mountains. The golden jackal is a social species, the basic social unit of which consists of a breeding pair and any young offspring. It is very adaptable, with the ability to exploit food ranging from fruit and insects to small ungulates. They will attack domestic fowl and domestic mammals up to the size of domestic water buffalo calves. The jackal's competitors are the red fox, wolf, jungle cat, forest wildcat, and, in the Caucasus, the raccoon, and, in Central Asia, the steppe wildcat. The jackal is expanding beyond its native grounds in Southeast Europe into Central Europe, occupying areas where there are few or no wolves.
