Template:Short description Template:For Template:Speciesbox
The chukar partridge (Alectoris chukar), or simply chukar, is a Palearctic upland gamebird in the pheasant family Phasianidae. It has been considered to form a superspecies complex along with the rock partridge, Philby's partridge and Przevalski's partridge and treated in the past as conspecific particularly with the first. This partridge has well-marked black and white bars on the flanks and a black band running from the forehead across the eye down the head to form a necklace that encloses a white throat. Native to Asia, the species has been introduced into many other places and feral populations have established themselves in parts of North America, Malta and New Zealand. This bird can be found in parts of Middle East and temperate Asia.
DescriptionEdit
The chukar is a rotund Template:Convert long partridge, with a light brown back, grey breast, and buff belly. The shades vary across the various populations. The face is white with a black gorget. It has rufous-streaked flanks, red legs and coral red bill. Sexes are similar, the female slightly smaller in size and lacking the spur.<ref name="pcr">Template:Cite book</ref> The tail has 14 feathers, the third primary is the longest while the first is level with the fifth and sixth primaries.<ref name="fbi">Template:Cite book</ref>
It is very similar to the rock partridge (Alectoris graeca) with which it has been lumped in the past<ref name=watson>Template:Cite journal</ref> but is browner on the back and has a yellowish tinge to the foreneck. The sharply defined gorget distinguishes this species from the red-legged partridge which has the black collar breaking into dark streaks near the breast. Their song is a noisy chuck-chuck-chukar-chukar from which the name is derived.<ref name=fbi2>Template:Cite book</ref> The Barbary partridge (Alectoris barbara) has a reddish-brown rather than black collar with a grey throat and face with a chestnut crown.<ref name=johnsgard/>
Other common names of this bird include chukker (chuker or chukor), Indian chukar and keklik.
Distribution and habitatEdit
This partridge has its native range in Asia, including Israel, Jordan, Palestine, Lebanon, Syria, United Arab Emirates, Saudi Arabia, Oman, Turkey, Kurdistan, Iran, Afghanistan, Tajikistan, Pakistan and India, along the inner ranges of the western Himalayas to Nepal, as well as southeasternmost Europe in Bulgaria and Greece.<ref name="iucn"/> Further west in southeastern Europe it is replaced by the rock partridge, Alectoris graeca. It barely ranges into Africa on the Sinai Peninsula. The habitat in the native range is rocky open hillsides with grass or scattered scrub or cultivation. In Israel and Jordan it is found at low altitudes, starting at Template:Convert below sea level in the Dead Sea area, whereas in the more eastern areas it is mainly found at an altitude of Template:Convert except in Pakistan, where it occurs at Template:Convert.<ref name=pcr/><ref name=whistler/> They are not found in areas of high humidity or rainfall.<ref name=baker_gbi/>
It has been introduced widely as a game bird, and feral populations have become established in the United States (Rocky Mountains, Great Basin, high desert areas of California), Canada, Chile, Argentina, New Zealand and Hawaii.<ref>Long, John L. (1981). Introduced Birds of the World.

The chukar readily interbreeds with the red-legged partridge (Alectoris rufa), and the practice of breeding and releasing captive-bred hybrids has been banned in various countries including the United Kingdom, as it is a threat to wild populations.<ref name="GWCT">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Systematics and taxonomyEdit
The chukar partridge is part of a confusing group of "red-legged partridges". Several plumage variations within the widespread distribution of the chukar partridge have been described and designated as subspecies. In the past the chukar group was included with the rock partridge (also known as the Greek partridge). The species from Turkey and farther east was subsequently separated from A. graeca of Greece and Bulgaria and western Europe.<ref>Template:Cite journal</ref><ref name=christensen>Template:Cite book</ref>

Population and statusEdit
This species is relatively unaffected by hunting or loss of habitat. Its numbers are largely affected by weather patterns during the breeding season. The release of captive stock in some parts of southern Europe can threaten native populations of rock partridge and red-legged partridge with which they may hybridize.<ref name=Barilani/><ref name=Duarte/>
British sportsmen in India considered the chukar as good sport although they were not considered to be particularly good in flavour. Their fast flight and ability to fly some distance after being shot made recovery of the birds difficult without retriever dogs.<ref name="humegame" /> During cold winters, when the higher areas are covered in snow, people in Kashmir have been known to use a technique to tire the birds out to catch them.<ref name="Ludlow" />
Behaviour and ecologyEdit
In the non-breeding season, chukar partridge are found in small coveys of 10 or more (up to 50) birds. In summer, chukars form pairs to breed. During this time, the cocks are very pugnacious in their calling and fighting.<ref name=whistler/><ref name=baker_gbi/><ref name=finn/><ref name=hbk/> During winter they descend into the valleys and feed in fields. They call frequently during the day and especially in the mornings and evenings. The call is loud and includes loud repeated chuck notes and sometimes duetting chuker notes. Several calls varying with context have been noted.<ref name=Stokes/> The most common call is a "rallying call" which when played back elicits a response from birds and has been used in surveys, although the method is not very reliable.<ref name=Williams/><ref name=Bohl/> When disturbed, it prefers to run rather than fly, but if necessary it flies a short distance often down a slope on rounded wings, calling immediately after alighting.<ref name=pcr/><ref name=humegame/><ref name=oates/> In Utah, birds were found to forage in an area of about Template:Convert and travel up to Template:Convert to obtain water during the dry season. The home range was found to be even smaller in Idaho.<ref name=Walter/><ref name=Bump/><ref name=Phelps/>
The breeding season is summer. Males perform tidbitting displays, a form of courtship feeding where the male pecks at food and a female may visit to peck in response. The males may chase females with head lowered, wing lowered and neck fluffed. The male may also perform a high step stiff walk while making a special call. The female may then crouch in acceptance and the male mounts to copulate, while grasping the nape of the female. Males are monogamous.<ref name="christensen" /> The nest is a scantily lined ground scrape, though occasionally a compact pad is created with a depression in the centre. Generally, the nests are sheltered by ferns and small bushes, or placed in a dip or rocky hillside under an overhanging rock. About 7 to 14 eggs are laid.<ref name="baker_gbi" /><ref name="hbk" /><ref name="Hume" /> The eggs hatch in about 23–25 days. In captivity they can lay an egg each day during the breeding season if eggs are collected daily.<ref name="Woodard" /> Chicks join their parents in foraging and will soon join the chicks of other members of the covey.<ref name="johnsgard" />
As young chukars grow, and before flying for the first time, they utilize wing-assisted incline running as a transition to adult flight. This behaviour is found in several bird species, but has been extensively studied in chukar chicks, as a model to explain the evolution of avian flight.<ref name="TobalskeDial2007">Template:Cite journal</ref><ref name=Dialetal2006>Template:Cite journal</ref><ref name="Dial2003WAIR">Template:Cite journal</ref><ref name="BundleDial2003MechanicsOfWAIR">Template:Cite journal</ref>
Chukar will take a wide variety of seeds and some insects as food. It also ingests grit.<ref name=oates /> In Kashmir, the seeds of a species of Eragrostis was particularly dominant in their diet<ref name=Oakleaf/> while those in the US favoured Bromus tectorum.<ref name=johnsgard/> Birds feeding on succulent vegetation make up for their water needs but visit open water in summer.<ref name=Degen/>
Chukar roost on rocky slopes or under shrubs. In the winter, birds in the US selected protected niches or caves. A group may roost in a tight circle with their heads pointed outwards to conserve heat and keep a look out for predators.<ref name=johnsgard/>
Chukar are sometimes preyed on by golden eagles.<ref name="bbb">Template:Cite journal</ref>
Birds in captivity can die from Mycoplasma infection and outbreaks of other diseases such as erysipelas.<ref name=Lateef/><ref name=Pettit/><ref name=Dubey/>
In cultureEdit
The name is onomatopoeic and mentions of chakor in Sanskrit, from northern Indian date back to the Markandeya Purana (c. 250–500 AD).<ref>Template:Cite book</ref><ref>Template:Cite book</ref> In North Indian and Pakistani culture, as well as in Hindu mythology, the chukar (referred as Chakor) sometimes symbolizes intense, and often unrequited, love.<ref name="temple1884" /><ref name="jasb1881">Template:Cite journal</ref> It is said to be in love with the moon and to gaze at it constantly.<ref name="balfour1871">Template:Cite book</ref> Because of their pugnacious behaviour during the breeding season they are kept in some areas as fighting birds.<ref name=baker_gbi/><ref name=finn/>
