Alectoris chukarchukar(Also: Chukar partridge)

Geographic Range

Fourteen subspecies of Alectoris chukar are currently recognized. Populations in North America are thought to derive from an Indian subspecies, A. c. chukar, though several subspecies have probably intermixed. The native distribution ranges across mountainous areas of the Middle East and Asia from eastern Greece and southeastern Bulgaria through Asia Minor east to Manchuria China. The chukar has been successfully introduced to North America, Hawaii and New Zealand as a game species. In North America, successful populations have established themselves in mountainous, rocky, arid areas throughout the western states and the current distribution is centered around the Great Basin area, including Nevada, western Utah, southwestern Idaho, northeastern California, and southeastern Oregon. In the east, game farm birds are released for hunting, but successful populations have not established themselves (Christensen 1996; Del Hoyo 1994).


Alectoris chukar can be found in North America throughout the west in steep, mountainous, rocky locations in mixed habitat types. The Great Basin area of desert shrub is representative of their preferred habitat; climate is arid to semiarid, water is generally available from scattered sources, and temperature varies. The grazed and disturbed public lands provide plentiful grasses and seeds with scattered shrubs while the rocky terrain provides cover. In North America, such areas are generally inaccessible and not near cultivated land, though they will use such areas when available. Unsuccessful attempts to introduce the chukar into other areas of North America suggest that they are already established in most suitable habitat types (Christensen 1996).

Physical Description

Alectoris chukar is a medium-sized partridge. Males (510-800g) are slightly larger than females (450-680g) in length and mass. Plumage pattern is similar for both sexes and distinctive among game birds of North America. Chukars are gray-brown above with a buff belly. A dark black line across the forehead, eyes, and down the neck contrasts the white throat from the gray head and breast. Flanks are prominently barred black and white-chestnut and the outer tail feathers are chestnut. Bill, margins of eyelids, legs and feet are corral pink to deep red or crimson. Both sexes can have a small tarsal spur, but usually this is characteristic of males. Juveniles are smaller and are mottled brown and gray, with only slight brown barring on flanks. In its native habitat, coloring can vary geographically; birds in more arid areas tend to be grayer and paler (Christensen 1996; Del Hoyo 1994; National Geographic Society 1999).

Chukars are monogamous. Pairs form in mid-March after a male performs a courtship display involving a head-tilt and a showing of his barred flanks. Both begin to call and participate in a "tidbitting display" pecking at various objects. During drought seasons, when food is scarce, breeding may be restricted to a few birds. Males guard the female from access by other males(Christensen 1996; Del Hoyo 1994).

Nests are simple scrapes, sometimes lined with grass or feathers, in rocky or brushy areas. They are difficult to find and are not well studied. Clutch sizes vary with site and environmental condition between seven and twenty one. Incubation lasts approximately 24 days and is usually a female activity. Hatching can occur from May until August, depending on the success of the first clutch. Broods average around 10.5 chicks, but fluctuate. Young are precocial, or highly developed upon hatching, and are capable of flight within a few weeks. They reach adult size in 12 weeks. Males are thought to remain until chicks are reared, though some are reported to leave after clutch completion and regroup with other males. Much remains to be learned about the reproductive habits of the chukar. (Christensen, 1996; Del Hoyo, et al., 1994)

  • Breeding interval
    Chukars breed once yearly depending on environmental conditions.
  • Breeding season
    Breeding occurs from April to July in North America.

Young are cared for by their mother and perhaps father until they reach independence. Young are precocial, they fly within a few weeks of hatching and reach adult size by 12 weeks old. (Christensen, 1996; Del Hoyo, et al., 1994)

Chukars are diurnal and forage on the ground throughout the morning and afternoon. They do not migrate and any seasonal movements are altitudinal. Flight is generally restricted to short distances downhill, usually when flushed. They hop when crossing rough terrain and prefer running to flight. The primary social group is a covey, consisting of varying numbers of adults and their offspring, and the largest groups are found at water sources. Larger unrelated groups form in the winter. Chukars roost on the ground under brush or outcrops. Males actively defend their nesting territories (Christensen 1996; Del Hoyo 1994). (Christensen, 1996; Del Hoyo, et al., 1994)

Communication and Perception

Chukars use a number or vocalizations in interactions that are divided into three categories: alarm social contact, agonistic, and sexual. The most common call is a low chuck, chuck, chuck used by both sexes that changes gradually to a chukar chukar and can be heard from long distances, hence the name chukar. Communication presumably also occurs through visual cues. (Christensen, 1996; Del Hoyo, et al., 1994)

Food Habits

Chukars are generally opportunistic and forage on vegetation, including grass and forb seeds, green grass, forb leaves, and some shrub fruits, according to relative abundance and seasonal availability. On western rangelands, primary foods are seeds and foliage of introduced grasses and various forbs in the sagebrush community. Cultivated grains are used when available, but chukar habitat in North America is generally not near agricultural land. In Hawaii, different foods are available, but native shrub fruits and introduced herbaceous plants are still important. Young chicks primarily eat insects. Adults do not eat a significant number of insects, but are known to take locusts when available. All types of water sources are utilized by chukars and tend to dictate distribution during the hot summer months; they will stray farther from water in the winter when green vegetation is available (Christensen 1996; Del Hoyo 1994; Cole et al. 1995).

Economic Importance for Humans: Positive

Alectoris chukar was first introduced to North America in 1893 as a game species and provides revenue to state wildlife agencies through hunting. The difficult, steep, often remote terrain they occupy provides a challenge and thrill to hunters and the meat is considered very tasty. In Hawaii, chukars have been found to occupy an important niche once occupied by now extinct native birds; they aid in the dispersal and germination of seeds from important native plants and thus may be beneficial in restoring degraded ecosystems (Christensen 1996; Cole et al. 1995).

Economic Importance for Humans: Negative

Chukars also aid in the dispersal and germination of invasive non-natives, such as cheat grass in North America. Also, they are susceptible to several avian diseases and might act as a vector for infections that can be passed from avian hosts to humans, such as Chlamydia, when raised in game-farming situations (Christensen 1996; Erbeck and Nunn 1999).

Conservation Status

Alectoris chukar are not globally threatened. In most areas, populations are stable or increasing, though habitat loss and intensive hunting may affect some local populations in their native distribution. There may be some concern for wild populations due to the possibility of disease transmission from domestic chickens and turkeys. In North America, they have been managed for hunting since their introduction. In most areas, states try to increase hunting through liberal bag-limits and long hunting seasons to overcome low yields due to the inaccessible and remote nature of their habitat. Habitat management includes developing and improving water sources. Monitoring populations through different methods of collaring and radio-transmitters has been explored (Christensen 1996; Del Hoyo 1994; Waters et al. 1994).

Other Comments

Much research still needs to be done to determine the habits and needs of Alectoris chukar. Information is somewhat limited in many areas of their natural history. In addition, research can be done to determine the current relatedness of North American chukars to the original old world subspecies (Christensen1996).
