tomares romanovi , or romanoff ' s hairstreak , is a butterfly of the family lycaenidae . it is found in armenia , azerbaijan , georgia , eastern turkey , northern iran , and kopet dagh mountains .

similar species are : provence hairstreak or cardenillo , tomares ballus ( fabricius , 1787 ) it is found in the iberian peninsula , northern africa and along the mediterranean coast of provence , france .

the species is distributed in armenian highland , georgia , kopet - dagh . armenia is inhabited by nominate subspecies .

the species inhabits calcareous grasslands and arid mountain steppes , usually dominated by tragacanth locoweeds . host plant is astragalus finitimus , although for kopet dagh the astragalus schahrudensis is known . the species is specialized to feed on flowers of the host plant , and the female lays down the eggs on the flower buds .

flight period lasts from mid april to mid june , depending on elevation , in single generation .

. in the studied period it shows moderate decline ( p < 0 . 05 ) . the host plant probably suffers from overgrazing in two ways : directly and due to total degradation of habitat and erosion .

it was evaluated for the red book of animals of armenia and was considered as vulnerable . at current some portions of the populations of the species are protected in khosrov forest state reserve , and gnishik community protected area . two populations of the species which have not been covered by arevik national park are included now in

pbas , also the significant portion of its population is included in gnishik pba . in their turn the mentioned pbas are in the process of being included in the network of emerald sites . continuation of the monitoring of the species is a necessary measure to track further dynamics of its populations . further grow of pba network and development of butterfly - watching with strong support of community service is another important conservation tool that can decrease the load on the grassland ecosystems and support in stabilization of population trend .

status . a rare species . according to iucn criteria categorized as vulnerable vu b1ab ( iii ) + b2ab ( iii ) .

brief description . a small–sized butterfly , the length of the forewing is 15 - 19 mm . the fround color of the wings is black with bright red spot on the discal part of forewings and on the anal part of hind wings . the underside of the hind wings is light green with metallic iridescence .

distribution in armenia . central and south armenia . recorded in the kotayk ( garni and geghadir villages , jrvezh settlement , mt . hatis ) , vayots dzor ( artavan village ) , ararat ( urtsalanj village ) , syunik ( surroundings of the shvanidzor village ) provinces and in khosrov forest reserve .

habitats . semi–deserts , dry meadows , steppes , grasslands near the timberline at the altitudes of 1300–2200 m above sea level .

biological traits . flies in a single generation from mid - may to the end of july . pupae winter . the larvae develop in the flower buds of astragalus finitimus ( fabaceae ) .

population size and its trends . abundance is rather great in places without human facilities , depends on the densities of the fodder plant .

suggested conservation measures . incorporation of species habitats to the reserve zone of arevik national park . application of selective effect insecticides in aircraft treatments against leaf - eating forest pests .

habitat : dry rocky slopes with sparse vegetation , debris , beams , ravines .

behavior : usually sits on the soil or small stones , sometimes feeds on flowers , on favorit in spain are platycapnos spicata . males are territory - assertive , that is , they either fly up and chase anyone who dares to enter the territory , or they fly into the whirling " dance - flight " around each other high into the air in a sort of territory battle . females are less flying around , often seen on the flowers of nectary , or lay eggs on foodplants .

flight season : depending on the height above sea level , the season is from the end of january until early may .

foodplants : caterpillars which feed on hairy canary clover , dorycnium hirsutum and different medicago species .

distribution : iberian peninsula , northern africa and along the mediterranean coast of provence , france .

prolibytherium ( " before libya 's beast " ) is an extinct artiodactyl ungulate native to early miocene north africa and pakistan , from around 16.9 to 15.97 million years ago .

the 1.80 metres ( 5 ft 11 in ) long creature would have superficially resembled an okapi or a deer .

unlike these , however , prolibytherium displayed dramatic sexual dimorphism , in that the male had a set of large , leaf-shaped ossicones with a width of 35 centimetres ( 14 in ) , while the female had a set of slender , horn-like ossicones .

at one time , it was described as a relative of sivatherium ( as a precursor to " libytherium maurusium " ( s. maurusium ) ) .

male ( a ) and female ( b ) forms of prolibytherium magnieri . p . fusus would have had similar ornaments . art by i . sánchez .

meaning : prolibytherium means “before libya’s beast” , coined by camille arambourg in 1969 for a different species , while fusus refers to the fused occipital condyles at the back of the skull .

the taxonomic status of prolibytherium remains in flux . at one time , it was described as a relative of sivatherium ( as a precursor to " libytherium maurusium " ( sivatherium maurusium ) ) . later , it would be regarded as a palaeomerycid , or either as a climacoceratid , or as a basal member of giraffoidea . with the discovery and study of a female skull in 2010 , prolibytherium is tentatively regarded as a climacoceratid .

in any list of weird fossil mammals , the regular set of ancient beasts are trotted out . there’s always a brontothere . uintatherium often shows up . deinotherium isn’t a surprise , either . and while these long lost mammals are indeed wonderful , there are plenty of critters that are just as strange . one of my favorites is prolibytherium .

exactly what sort of beast prolibytherium was , no one knows for sure . the herbivore has been punted around the hoofed mammal tree a bit , and , for the moment , it seems closest to a group of extinct , deer - like mammals called climacoceratids . but one thing is for sure – this mammal wore some very bizarre headgear .

the 1 . 80 metres ( 5 ft 11 in ) long creature would have superficially resembled an okapi or a deer . unlike these , however , prolibytherium displayed dramatic sexual dimorphism , in that the male had a set of large , leaf - shaped ossicones with a width of 35 centimetres ( 14 in ) , while the female had a set of slender , horn - like ossicones .

the first species , named by camille arambourg from the 16 million year old rock of libya , had a massive , splayed appendage growing from between its eyes and over the back of the head . and as israel sánchez and colleagues argued in 2010 , these ornaments differed between the sexes , with probable females having minimalist spikes that more or less present the framework on which the broader male palms are supported . and now melinda danowitz , rebecceca domalski , and nikos solounias have named a new species of this unusual mammal , extending the range of prolibytherium into asia and its span back three million years .

the new species , prolibytherium fusus , is only known from a 19 million year old braincase with the broad ornaments broken off . yet , aside from the fractured attachments for the appendages , the back of the skull shows that this species must have had heavy appendages like its geologically younger relative . the occipital condyles – the attachment sites between the back of the skull and the front of the neck – are fused and thickened , providing greater support along the midline for carrying all that extra bone around . and , danowitz and colleagues note , the reinforcement at the back of the skull might have had provided greater reinforcement for combat , too , although how these butterfly - faced mammals fought is so far left to our cenozoic imagination .

larvae can be found from autumn to the end of may .

elachista unifasciella

elachista unifasciella <EOT> vingbredd 9–10 mm . en vackert , kontrastrikt tecknad gräsminerarmal med brunsvarta framvingar , på mitten försedda med ett krämfärgat tvärband som vidgar sig något mot bakkanten . fransarna är vita vid spetsen utanför en svartaktig delningslinje . arten liknar ganska mycket lundskaftingminerarmal elachista gangabella , men denna art saknar de ljusa fransarna vid vingspetsen . denna karaktär är oftast svår att se , i synnerhet på slitna djur . arten är avbildad av traugott - olsen & nielsen ( 1977 ) .

notes : rare ( proposed as a future red data book species ) on grassland in southern england , north to worcestershire . in hampshire known only from leckford , but not recorded in the county since 1986 . not recorded from the isle of wight to date . wingspan 9 - 10 mm . formerly lumped with e . obliquella and very similar to several other elachista species with worn females of e . bisulcella in particular frequently misidentified as this species . larva mines leaves of cock ' s - foot and false - brome .

den är funnen i centraleuropa inklusive england . i danmark är den funnen i ett brett band från nordöstra själland till södra jylland . dess nordgräns går genom skåne , där den har påträffats på flera platser . den rapporterades som ny för landet 1965 genom fynd i skåne , gärdslöv 20 . vi . 1964 ( i . svensson leg . ) där den fortfarande av allt att döma finns kvar . ca 1990 påträffades den också i bökeberg norr om svedala . arten är lokal och i allmänhet sällsynt , men här och där kan den vissa år anträffas i något större numerär .

endast känd från en handfull lokaler i skåne där den lever i mörk lundskog . arten lever troligen på flera gräsarter exempelvis hundäxing ( dactylis glomerata ) . fjärilens miljöer är i dagsläget inte hotade och någon minskning har inte kunnat påvisas . dock är utbredningsområdet litet , antalet lokaler få och arten är lätt igenkänlig , varför mörkertalet förmodligen är litet . antalet lokalområden i landet skattas till 5 ( 3 - 8 ) . utbredningsområdets storlek ( eoo ) skattas till 4600 ( 400 - 4600 ) km² och förekomstarean ( aoo ) till 20 ( 12 - 32 ) km² . - 2005 . det finns inga tecken på betydande populationsförändring . de skattade värdena som bedömningen baserar sig på ligger alla inom intervallet för kategorin nära hotad ( nt ) . de skattade värdena för utbredningsområde och förekomstarea ligger under gränsvärdet för starkt hotad ( en ) . detta i kombination med att utbredningsområdet är kraftigt fragmenterat och antalet lokalområden är extremt få gör att arten uppfyller kriterierna för kategorin nära hotad ( nt ) . ( b1a + 2a ) .

bokskogsgräsminerarmal finner man i bokskogar , som dess namn anger , helst i partier som är omväxlande beskuggade av träden . larven gör långsträckta minor i blad av hundäxing dactylis glomerata . i litteraturen anges också lundskafting brachypodium silvaticum som värdväxt . larven lever i maj i minan då den förpuppar sig . fjärilen kläcks i mitten av juni och flyger ca en månad .

med gällande lagar skyddas till stor del de skånska bokskogarna , men man bör utse något eller ett par referensområden för att kunna följa artens utveckling .

i det avancerade verktyget kan man söka ut och få fram artlistor , t ex arter i ett visst län , i en viss biotop , substrat , som påverkas av en hotfaktor , eller som är knutna till en sk värdart , t ex trädet alm . dessa kan även kombineras .

söka fram arter som är rödlistade , knutna till alm , är beroende av död ved och som finns i kronobergs län .

söka fram arter som är rödlistade , lever i småvatten och som påverkas negativt av igenväxning .

defaultläget i verktyget är arter som är rödlistade 2015 och dessa är klassade på samtliga sökfaktorer . under fliken rödlistekategori kan man dock välja att även inkludera arter som inte är rödlistade . om man väljer att inkludera icke rödlistade arter behöver man vara medveten om att samtliga arter inte är klassade på samtliga faktorer . nedan en sammanställning av vad som är komplett .

denna funktion används när du vill skapa din egen lista av arter att hantera . du kan t . ex . navigera mellan arterna i listan genom att klicka på deras namn . du kan också välja att använda knappen ”jämför arter” för att se bilder , kartor och kännetecken i en jämförelsevy .

du kan komponera ditt eget urval av arter genom att klicka dig fram via släktträdet och där välja arter eller artgrupper till din lista . ett annat sätt att göra ditt urval är att använda fliken ”filtrera” , där du kan söka på olika egenskaper . ovanför listan med sökresultatet finns en knapp ”lägg i mitt urval” .

in autumn the larva makes a long , somewhat blistered , slightly transparent corridor . in spring it mines the basal leaves that lie on the ground . these mines are swollen , clouded green , opaque , and the mined tips of the leaves are puckered and shrunken , filled with frass ( bladmineerders van europa ) .

larva : the larvae of moths have a head capsule and chewing mouthparts with opposable mandibles ( see video of a gracillarid larva feeding ) , six thoracic legs and abdominal legs ( see examples ) .

rather thick , light yellow ; head light brown . see steuer ( 1973a ) for an illustration of the characteristic sclerites in the pronotum , prosternum , and anal shield ( bladmineerders van europa ) .

pupa : the pupae of moths have visible head appendages , wings and legs which lie in sheaths ( see examples ) .

see patocka ( 1999a ) and patocka and turcani ( 2005a ) ( bladmineerders van europa ) .

adult : the adult is not illustrated in ukmoths ( check for update ) . the species is included in urltoken .

the wingspan is about 31.4 mm .

the forewings are streaky medium-grey to dark brown-grey with streaks of warm light orange tan to yellow tan at the postreniform patch , in the fold , and in the large pointed claviform spot .

a thin tan line parallels the margin near the anal angle .

the reniform and orbicular spots are outlined in black with paler peripheral and darker central scaling .

the distal forewing is streaky due to black veins and pale-grey scales and the transverse lines are obsolete .

the hindwings are light whitish grey with brown-grey marginal shading and dark veins , darker in females .

adults are on wing from late march to early june .

the larvae feed on artemisia californica and ericameria laricifolia .

the ross 's goose ( anser rossii ) is a north american species of goose .

this goose breeds in northern canada , mainly in the queen maud gulf migratory bird sanctuary , and winters much further south in the continent in the southern united states and occasionally northern mexico .

the plumage of this species is white except for black wing tips .

it is similar in appearance to a white-phase snow goose but approximately 40 % smaller .

other differences from the snow goose are that the bill is smaller in proportion to its body and lacks " black lips " .

the dark phase is extremely rare .

the ross 's goose is a rare vagrant to western europe , but it is commonly kept in wildfowl collections and so the true frequency of wild birds is hard to ascertain .

escaped or feral specimens are encountered frequently , usually in the company of other feral geese such as canada goose , greylag goose and barnacle goose .

however , individuals or small groups that seemed to be of natural origin have turned up in the netherlands and britain .

this species is named in honor of bernard r. ross , a hudson 's bay company factor at fort resolution in canada 's northwest territories .

ross ' s goose

ross ' s goose <EOT> ross’s goose is much smaller than a snow goose . it is about the size of a mallard .

similar species : the snow goose , discussed above . note also that hybrids between snow goose and ross’s goose are not rare .

ross ' s goose , chen rossii , and hybrids , in new york .

hybrid and ross ' s goose , cayuga lake , seneca co . 2 march 2002 .

ross ' s goose , savannah mucklands , wayne co . , ny , march 2004 .

there is a very rare blue morph of ross’s goose , which was only confirmed in 1971 .

although ross ' s goose is usually smaller than snow goose , size in itself is not diagnostic . it is a good clue , however , and noticeably small birds in a flock should be looked at closely when searching for ross ' s . primary structural differences of ross ' s goose as compared to snow goose include :

in missouri , most large goose flocks anywhere in the state often have a few ross’s geese present .

we took these photos of a more typical ross ' s goose two days later on 13 march 2004 .

very rarely a ross ' s goose can be found that is dark - colored like a blue morph snow goose . these blue morph ross ' s geese are thought to be the result of hybridization with snow geese .

ross ' s goose is classified as least concern ( lc ) on the iucn red list ( 1 ) .

the plumage of ross ' s goose is typically very white and rarely attains the rusty staining which snow goose often does , particularly about the head and neck .

ross’s goose hatchlings are able to leave the nest after just 24 hours , and are able to feed themselves and swim .

ross’s goose has a rare blue colour morph , whose existence was not confirmed until as recently as 1971 ( 2 ) .

rosss _ goose _ and _ canada _ goose _ 2 - 17 - 15 . jpg

the male ross’s goose has wart - like swellings at the base of the bill , which are thought to be a status symbol .

the ross ' goose is a small goose , similar in appearance to the snow goose . like the snow goose , the ross ' goose has a light and dark morph , although the dark - morph ross ' goose is extremely rare . the light morph is white , and the dark morph is gray with a white head . both morphs have black primaries . the bill is small and lacks the ' grin - patch ' seen on the snow goose . juveniles are mostly gray .

image h is of a ross ' x snow goose hybrid showing intermediate head and bill characters . note the reduced bevelled gap between the mandibles as compared to snow goose and the darkish area at the base of the upper mandible from ross ' s goose . the bill is longer than that of ross ' s and the feathering at the base of the bill is intermediate between parent species .

a tiny white goose with black wingtips , the ross ' s goose is like a miniature version of the more abundant snow goose . it breeds in the central arctic and winters primarily in central california , but it is becoming more frequent farther east .

ross’s goose has a rounded head , stubby bill , and short neck , and lacks the black “lipstick” patch on the bill that snow geese have .

image d is a digiscoped shot showing 3 ross ' s geese followed by a snow goose along with canada geese . differences in size and structure between the ross ' s geese and snow are very apparent in this image . note the dark line before the eye in the rear pair of ross ' s which is retained juvenal plumage . juvenile ross ' s geese typically show far less duskiness to their plumage than juvenile snows , and a dark line before the eye is the most consistent plumage character suggesting immaturity in ross ' s goose and can be seen at a surprising distance even in flying birds .

ross’s goose is an uncommon migrant in missouri . as a winter resident , it is uncommon ( in the west ) to rare ( in the east ) .

ross’s goose looks a lot like the snow goose and , like that species , has a white and a “blue” color pattern ( morph ) . like the snow goose , the white form of ross’s goose is all white with dark primaries and gray primary coverts . the key to telling the two species apart is body size and bill shape and color . ross’s goose is the size of a mallard and has a short neck and rounded head ; the pink bill is stubby and lacks the black “lipstick” or “grinning” patch . on close inspection , a blue - green warty patch saddles the upper bill near the base . the “blue goose” or dark morph is very rare . the voice is a high - pitched honking sound , similar to the snow goose’s but higher and not as shrill .

population apparently still increasing , as with some other arctic - nesting geese ( snow and white - fronted ) . ross ' s goose often hybridizes with snow goose , but evidently not enough to be genetically " swamped " by the snows .

image m shows a ross ' s and two snow geese . there is a noticeable size difference between this ross ' s and the snows and the structural differences are very apparent . as pertaining to the ross ' s goose , note the shorter , rounder body , shorter neck , less elongated head with vertical feathering at the bill base , and short stubby bill with no apparent dark gap between the mandibles .

the call of ross’s goose is a sad , murmuring ‘ mmmmm ’ or ‘ uuuhhhh ’ , which is used for contact , especially when groups are in danger ( 2 ) .

ross ' s goose populations are relatively small , but appear to have increased since the 1990s . the species is not on the 2014 state of the birds watch list . back to top

the oldest known ross ' s goose was a female , and at least 22 years , 6 months old when she was shot in california in 1993 . she had been banded in 1972 in saskatchewan .

in the identification guide to north american birds part 2 , pyle states the range in size of the gap along tomia in lesser snow goose as 7 - 12 mm wide and in hybrids as 4 - 9 mm wide . the gap between mandibles in ross ' s goose is narrower forming no or a thinner dusky stripe along tomia . many ross ' s geese show a slight gap between the mandibles .

image n is a closer crop for comparison of the structural differences between snow and ross ' s geese which are apparent in flight .

image l is closer crop of the hybrid and trailing snow goose showing differences in structure . the body and neck of the hybrid suggest ross ' s goose but the head and bill are clearly intermediate between the species . the dark gap between the mandibles can be seen better in this crop .

in this shot the hybrid is on the right , and is quite obviously smaller than the snow geese . the ross ' s goose is to the left , just sticking its head out from behind the larger geese .

as it is such an abundant species , there do not seem to be many threats to the future survival of ross’s goose , although habitat loss , disease ( 5 ) and hybridisation with the snow goose ( chen caerulescens ) may affect population numbers in the future ( 2 ) ( 4 ) .

rosss _ goose _ on _ lawn _ 2 - 17 - 15 . jpg

prior to the 1950s the ross ' s goose was confined to well - defined breeding and wintering areas , with few seen as strays . since that time the species has been expanding eastward , both on the breeding and wintering grounds . the change in breeding distribution has resulted in more contact and subsequent hybridization with the snow goose .

the breeding range of ross’s goose has been made a federal migratory bird sanctuary , which offers it a small amount of protection ( 5 ) , although there are not currently known to be any other conservation measures in place for this abundant species .

uncommon migrant . as winter resident , uncommon ( west ) to rare ( east ) . ross’s goose is a gamebird in missouri . populations of ross’s and snow geese have increased to a historically high level . as a result , they are overgrazing their arctic nesting range and degrading large areas of the tundra where other species nest . wildlife agencies have been trying to control the population size through various methods .

the breeding range of ross’s goose spreads throughout the canadian arctic . in winter , flocks mostly migrate to california , although congregations can also be found in texas and northern mexico ( 2 ) ( 3 ) ( 4 ) ( 5 ) ( 6 ) . the range of this species is thought to be spreading east ( 4 ) . there have been reports of vagrant ross’s geese in the netherlands ( 2 ) ( 6 ) .

ross’s geese forage in marshes , rivers , lakes , and crop fields , including cornfields and new winter wheat fields , for grains , roots , grasses , and aquatic vegetation .

image b shows a ross ' s goose . note the rounded and less elongated head and more vertical feathering at the base of the bill . the bill is short and stubby with almost no gap between the mandibles . note also the grayish base to the upper mandible .

ross’s goose has an herbivorous diet , which consists of roots , leaves , stems , sedges , legumes and domestic grains ( 2 ) ( 4 ) ( 5 ) . this species can be seen foraging on the ground individually , or may form larger groups ( 5 ) .

a migratory species , ross’s goose leaves its breeding ground in mid - october and arrives in its overwintering range in late october . flocks begin to return to the breeding grounds in early march . while migrating , this species is highly gregarious and forms large flocks ( 5 ) .

we noticed two small white geese in with a massive snow goose flock on the west side of cayuga lake , offshore of seneca co . ( along with two small canada geese , now cackling geese ) . pete hosner , who had recently worked in the arctic as a field assistant on snow goose research , declared that the slightly larger bird with a more rounded bill / face margin would have been called a ross ' s x snow goose hybrid in their study area .

this pint - sized relative of the snow goose has been surrounded by mystery and surprise . explorers recognized it as a different bird as early as 1770 , but it was not described to science until 1861 ; its arctic nesting grounds were not discovered until 1938 . once thought to be very rare , or even on brink of extinction , its population has greatly increased in recent decades . not until the late 1970s was it discovered that ross ' s , like snow goose , can occur in a “blue” morph . blue ross ' s geese are still rarely detected .

usually observed among groups of snow geese . occurs in marshes , sloughs , ponds , lakes , and reservoirs with aquatic vegetation . also forages in crop fields . more frequently seen in northwestern missouri , although most large goose flocks anywhere in the state often have a few ross’s geese present .

the female ross ' s goose does all of the incubation of the eggs . the male stays nearby and guards her the whole time . the female covers the eggs with down when she leaves the nest . the down keeps the eggs warm while she is away and may help hide them from predators .

the " real " ross ' s goose was tiny , with a very small , triangular bill . the posterior margin of the bill was very straight against the face , making a straight line , quite in contrast to the strong curve at the base of the snow geese ' s bills . it showed a dark green patch at the base of the bill and no sign of a dark grin patch at edge of the tomia .

image j is a crop of the 5 birds center - right in the image above , or in the front of the flock . this image approximates the look that one might have through the binocular or scope . the group is comprised of 3 snow geese and 2 ross ' s geese ( birds banked without shadows on their bellies ) . difference in size between the species is not apparent here but structural differences are very much so . note the shorter necks and more rounded , less elongated heads of the ross ' s . the more vertical line of feathering at the base of the smaller and stubbier bills of the ross ' s gives the appearance of having the face cut off at the front . from a distance in flight , the bill of ross ' s often virtually disappears and the vertical line at the front of the face is very apparent .

image k is also a crop of the same image showing birds in the lower left or at the rear of the flock . this group is comprised of 4 snow geese , a ross ' s ( bottom center ) and a hybrid ( second bird from top left ) . note the short neck , rounded head with vertical line of feathering at the bill base and short stubby bill of the ross ' s . this bird is also smaller than the others in this group . the hybrid shows a shorter , rounder body and shorter neck as well as a less elongated head than the snows , but the feathering at the bill base is convex lacking the vertically cut off look of ross ' s and is intermediate between the species . if one looks closely , there appears to be a relatively wide and dark gap between the mandibles which would not be as apparent at this distance in ross ' s .

ross ' geese are the smallest of the three varieties of white geese that breed in north america . the ross ' goose is a small white goose with black primary feathers . the bill is a deep reddish - pink with a paler nail and a variably bluish warty area over the base of the basal area . the legs and feet are rose - pink and the iris is dark brown . the sexes are dimorphic , with the female being 6 percent smaller than the male . the ross ' goose has a relatively short neck and lacks the black " grinning patch " that is typical of greater and lesser snow geese , for which it is often mistaken . ross ' geese may be distinguished from snow geese by their smaller size , more rapid wing beat and higher - pitched call .

the hybrid was small , but just a bit larger than the ross ' s goose . its bill was not quite so petit and triangular , but was still noticeably smaller and more triangular than that of a snow goose . the posterior margin of the bill was less curved than the snow geese , but was slightly curved . the base was dark green , but a dark line showed along the bill edge , much smaller than the grin patches of the snow geese , but visible .

ross’s geese overwinter in the southern part of their range , including ( uncommonly ) missouri , and return north in spring to the arctic tundra to breed . there , they make simple scrapes on the ground and typically lay 2 to 6 eggs .

during the breeding season ross’s goose is found in arctic tundra ( 2 ) ( 3 ) ( 5 ) , where it nests in open areas and on islands in shallow lakes ( 4 ) . in winter , large aggregations are found in agricultural fields and shallow wetlands ( 2 ) ( 4 ) ( 5 ) , using nearby reservoirs and lakes to roost ( 2 ) .

ross ' geese feed on grasses , sedges and small grains , particularly waste wheat and barley in the winter months .

historically , ross’s goose was threatened by hunting in its winter range , and this market drastically reduced wild populations and may have threatened this species with extinction . hunting became illegal in 1931 and the population has dramatically increased since ( 5 ) , causing north american authorities to change the law and allow hunting to resume , with the aim of reducing the population size by half ( 2 ) .

ross ' s goose ( chen rossii ) is a regularly occurring and often overlooked migrant and winter resident in kentucky in small numbers and is usually found in the company of snow geese ( chen caerulescens ) . identification of these species is relatively straightforward based primarily on structural differences , particularly those of head and bill shape . hybrids of these species are sometimes encountered and are intermediate in structure between the two .

ross’s goose ( chen rossii ) is a very small ( 4 ) , all - white goose , with black tips to its wings ( 3 ) ( 4 ) . the short , delicate bill is black - pink at the base , becoming brighter pink ( 3 ) towards the rounded tip ( 5 ) . the male has small , wart - like growths on the base of its bill , which become more prominent as it ages ( 5 ) . the distinctive legs are pink and the eyes are dark ( 2 ) ( 3 ) .

the population of ross ' geese was estimated at only 2 , 000 to 3 , 000 individuals in 1931 . protection from hunting has helped the ross ' goose population recover to a 1988 total of 188 , 000 breeding birds , although it is still listed as a species - of - concern on the partners in flight watch list . still on the increase , populations are now thought to be expanding their range greatly - - birds have been found farther east and west in recent years during migration . most nesting occurs within a refuge , and hunting is still prohibited , but loss of migration stopover and wintering habitat continues to threaten the ross ' goose .

of course , it is not practical to believe that one would have time to scrutinize or identify every bird in every flock flying overhead , but with practice and good views , some ross ' s geese and hybrids can be identified in flight based on structural characters .

the arctic nesting grounds of the ross ' goose , not discovered until 1938 , consist of tundra , marshes , and ponds . in winter and during migration , these geese can be found in shallow lakes , fresh - water marshes , flooded fields , and other agricultural lands .

the ross ' goose is a rare species , but is becoming more common in washington . you may occasionally find it mixed in with snow geese or other mixed - species flocks in the winter in the lowlands on both sides of the cascades , in both fresh - and saltwater habitats . flocks of up to 30 ross ' geese have become fairly regular in the spring and fall in far - eastern washington .

the female ross’s goose is around six percent smaller than the male ( 5 ) , with very few wart - like growths on the base of its bill , a shorter neck and a flatter forehead . the juvenile is brown - grey on the head , back and breast , with darker flight feathers ( 2 ) . the bill and feet are grey in the juvenile , gaining their pink colouration as the individual ages ( 4 ) .

ross ' geese are among the first to leave the breeding grounds in canada . the california central valley is currently the main wintering area for ross ' geese , but increasing numbers are wintering in arkansas , louisiana , new mexico , texas and the north - central highlands of mexico .

almost exclusively plant - eaters , ross ' geese eat grasses , sedges , and grain . in the fall , they eat more seeds and grains than grasses .

the vast majority of the population nests in the queen maud gulf migratory bird sanctuary in the central canadian arctic . they migrate to california ' s central valley , often in mixed flocks with other geese .

ross ' geese breed in the low arctic tundra , mainly near queen maud gulf , southern southampton island , the western coast of hudson bay and the sagavanirktok river delta in alaska . they usually nest in colonies mixed with lesser snow geese , making their nests on the ground in sparsely vegetated areas . female ross ' geese lay an average of 3 - 4 eggs .

hybrids are best identified by intermediate head and bill characters such as bill size and shape , line of feathering at bill base , degree of bevelling or gap along tomia , and varying amounts of grayish at bill base which snow goose lacks .

between late may and june mated pairs arrive at the breeding grounds and immediately establish a nesting territory . although ross’s goose is thought to be monogamous , copulation with other individuals outside of the pair is also known to occur ( 2 ) . the female builds the nest during and after the territory establishment ( 5 ) . the nest is a shallow structure , with twigs , grass , moss and lichens in the outer layer and mostly down on the inner layer ( 2 ) . the female lays an average clutch of between 4 and 5 eggs ( 2 ) at the beginning of june ( 5 ) , which are laid at 36 - hour intervals ( 2 ) . the female incubates the eggs , while being guarded by the male ( 4 ) , and the eggs hatch between late june and july ( 5 ) . if the female leaves the nest , it will cover the eggs with a layer of down to keep the eggs warm and hide them from predators ( 4 ) . the young are able to leave the nest 24 hours after hatching , and can swim and feed themselves ( 4 ) ( 5 ) . for up to a year after birth , the young maintain an association with the adults ( 5 ) and may remain with them until the next breeding season . ross’s goose reaches sexual maturity after 2 or 3 years , and lives for up to 14 years in the wild ( 2 ) .

ross ' geese are usually in flocks , often mixed with snow geese . their tendency to roost in tight flocks and be easily attracted to decoys may have made them vulnerable to market hunters , who had a significant impact on the population . these geese typically forage on the ground , wading or swimming in shallow water .

first breeding at age of 2 or 3 years . courtship involves rapid head - dipping by both members of pair . breeds in colonies , usually associated with colonies of snow goose . nest site is often on island or shore of tundra lake , usually on edge of low thicket . the same site is often used for more than 1 season . nest is a bulky bowl of twigs , leaves , grass , moss , lined with down . female builds nest , beginning about the time the first egg is laid , continuing after incubation begins .

ross ' geese breed in colonies , starting in their second or third year . the nest is on an island or the shore of a tundra lake , often situated at the edge of a low thicket . the nest , built by the female after she lays her first egg , is a bulky pile of leaves , grass , and moss , depressed in the middle and lined with down . the female lays a total of 4 eggs and incubates them for about 3 weeks . the young leave the nest shortly after hatching . the parents lead the young to water and food , and the goslings feed themselves . the male stands guard and actively defends the young against predators . the young fledge at 40 to 45 days .

anser rossii ( del hoyo and collar 2014 ) was previously placed in the genus chen .

justification : this species has a very large range , and hence does not approach the thresholds for vulnerable under the range size criterion ( extent of occurrence < 20 , 000 km2 combined with a declining or fluctuating range size , habitat extent / quality , or population size and a small number of locations or severe fragmentation ) . the population trend appears to be increasing , and hence the species does not approach the thresholds for vulnerable under the population trend criterion ( > 30 % decline over ten years or three generations ) . the population size is extremely large , and hence does not approach the thresholds for vulnerable under the population size criterion ( < 10 , 000 mature individuals with a continuing decline estimated to be > 10 % in ten years or three generations , or with a specified population structure ) . for these reasons the species is evaluated as least concern .

the swans , geese and ducks are mid - sized to large birds most commonly found on or near water . most have plump bodies , long necks and short wings . most feed while on the water , diving or merely tilting their bodies so that their heads and necks are submerged to search for fish , plants and invertebrates . washington representatives of the order all belong to one family :

the waterfowl family is represented in washington by two distinct groups—the geese and swans , and the ducks . whistling - ducks are also considered a distinct subfamily , and , although they have not been sighted in washington in many years , fulvous whistling - ducks have been recorded historically in washington and remain on the official state checklist . all members of the waterfowl family have large clutches of precocial young . they hatch covered in down and can swim and eat on their own almost immediately after hatching .

as migrating geese fly overhead , they reassure us of the certainty of changing seasons . as the great conservationist aldo leopold wrote , “one swallow does not make a summer , but one skein of geese , cleaving the murk of a march thaw , is the spring . ”

as adults , and even more so as goslings and as eggs , geese are preyed on by a variety of predators . they influence the plant and animal communities in both summer and winter territories , and as they migrate , they play a role in every ecosystem they travel through .

about 350 species of birds are likely to be seen in missouri , though nearly 400 have been recorded within our borders . most people know a bird when they see one — it has feathers , wings , and a bill . birds are warm - blooded , and most species can fly . many migrate hundreds or thousands of miles . birds lay hard - shelled eggs ( often in a nest ) , and the parents care for the young . many communicate with songs and calls .
