The Altai snowcock (Tetraogallus altaicus) is a species of bird in the family Phasianidae. It is found in western Mongolia and adjacent areas of China, Kazakhstan and Russia. Its natural habitat is boreal forests.
The Altai snowcock was first described by Frederic Gebler in 1836. He was a doctor and naturalist who lived in the Altai region for forty years and named many previously unknown species. [3] There are two subspecies, Tetraogallus altaicus altaicus and Tetraogallus altaicus orientalis. [2]
The Altai snowcock is a plump, partridge-like bird. While most snowcocks are similar in size, the Altai might be the largest species with a length of around 57 to 61 cm (22 to 24 in) and a mean body mass of approximately 2.54 kg (5.6 lb) in females and 3 kg (6.6 lb) in males. [4] [5] [6] The head and neck are slatey-grey and there is a partial dark collar at the base of the neck. The upperparts are grey with white spots and the tail is black. The chin, breast and belly are white. The throat has a breastband of grey with patches of black. The primary and secondary feathers are black, the former having white bases which show as a white flash in flight. The beak is yellowish brown and the legs and feet reddish brown. [7]
The Altai snowcock is native to the mountain ranges of western Mongolia and southwestern Siberia. Its range includes in Russia the mountainous regions near Abakan, Sayan Mountains and the Tannu-Ola Mountains; and in Mongolia, the Mongolian Altai, the Govi-Altai, the Khangai Mountains, and the mountains east of Lake Khuvsgul. [8] The habitat is open mountainside above the tree line at altitudes usually ranging between 2,000 and 3,600 metres (6,600 and 11,800 ft). [7]
The Altai snowcock feeds on buds, shoots, roots, berries and insects and it also occasionally eats small rodents. About forty different species of plants have been recorded to be part of the diet. [7]
Populations of Altai snowcock are believed to be decreasing as a result of over-hunting and degradation of their habitat. However, in its Red List of Threatened Species, the IUCN lists this species as being of "Least Concern" because it has a wide distribution over an estimated 819,000 square kilometres (316,000 sq mi) and the number of mature birds is over 10,000 and not decreasing at such a rate as would justify their inclusion in a more vulnerable category. [9]
The Phasianidae are a family of heavy, ground-living birds, which includes pheasants, partridges, junglefowl, chickens, turkeys, Old World quail, and peafowl. The family includes many of the most popular gamebirds. The family is a large one, and was formerly broken up into two subfamilies, the Phasianinae and the Perdicinae. However, this treatment is now known to be paraphyletic, and more recent evidence supports breaking it up into three subfamilies: Rollulinae, Phasianinae, and Pavoninae. Sometimes, additional families and birds are treated as part of this family. For example, the American Ornithologists' Union includes the Tetraonidae (grouse), Numididae (guineafowl), and Meleagrididae (turkeys) as subfamilies in Phasianidae.
The black grouse, northern black grouse, Eurasian black grouse, blackgame, or blackcock, is a large game bird in the grouse family. It is a sedentary species, spanning across the Palearctic in moorland and steppe habitat when breeding, often near wooded areas. They will spend the winter perched in dense forests, feeding almost exclusively on the needles of conifers. The black grouse is one of 2 species of grouse in the genus Lyrurus, the other being the lesser-known Caucasian grouse.
The black-bellied sandgrouse is a medium large bird in the sandgrouse family.
The snowcocks or snowfowl are a group of bird species in the genus Tetraogallus of the pheasant family, Phasianidae. They are ground-nesting birds that breed in the mountain ranges of southern Eurasia from the Caucasus to the Himalayas and western China. Some of the species have been introduced into the United States. Snowcocks feed mainly on plant material.
The Caucasian snowcock is a snowcock in the pheasant family Phasianidae of the order Galliformes, gallinaceous birds.
The Caspian snowcock is a snowcock in the pheasant family Phasianidae of the order Galliformes, gallinaceous birds.
The Caucasian grouse or Caucasian black grouse is a large bird in the grouse family. It is closely related to the black grouse.
Perdix is a genus of Galliform gamebirds known collectively as the 'true partridges'. These birds are unrelated to the subtropical species that have been named after the partridge due to similar size and morphology.
Lagopus is a small genus of birds in the grouse subfamily commonly known as ptarmigans. The genus contains three living species with numerous described subspecies, all living in tundra or cold upland areas.
The black guineafowl is a member of the guineafowl bird family. It occurs in humid forests in Central Africa. It is a medium-sized black bird with a bare, pink head and upper neck. Little is known of its behaviour.
The Himalayan snowcock is a snowcock in the pheasant family Phasianidae found across the Himalayan ranges and parts of the adjoining Pamir range of Asia. It is found on alpine pastures and on steep rocky cliffs where they will dive down the hill slopes to escape. It overlaps with the slightly smaller Tibetan snowcock in parts of its wide range. The populations from different areas show variations in the colouration and about five subspecies have been designated. They were introduced in the mountains of Nevada in the United States in the 1960s and a wild population has established in the Ruby Mountains.
Philby's partridge or Philby's rock partridge, is a relative of the chukar, red-legged partridge and barbary partridges and is native to southwestern Saudi Arabia and northern Yemen. Although similar in appearance to other Alectoris species, Philby's partridge can be distinguished by its black cheeks and throat. Although not currently listed as an endangered species, the Arab Spring and destruction of its fragile habitat in the tribal areas of Northern Yemen had led to concerns about the survival of this species. The name commemorates the British explorer St John Philby.
The Hainan partridge is a species of bird in the family Phasianidae. It is endemic to Hainan Island, China. Its natural habitats are primary evergreen forests. It is threatened by habitat loss and has been assessed as a vulnerable species.
The bar-backed partridge, also known as the brown-breasted hill-partridge, is a species of partridge in the family Phasianidae. It is found in southwestern China and Southeast Asia.
The Taiwan partridge or Taiwan hill partridge is a species of bird in the family Phasianidae. It is found only in Taiwan, and its natural habitat is broadleaf forests. It is threatened by habitat loss, but at present is categorised by the International Union for Conservation of Nature (IUCN) as being of least concern.
The red-breasted partridge, also known as the Bornean hill-partridge, is a species of bird in the family Phasianidae. It is endemic to hill and montane forest in Borneo, preferring bamboos and thickets. The International Union for Conservation of Nature (IUCN) has assessed it as a least-concern species.
The rufous-throated partridge is a species of bird in the family Phasianidae. It is found in montane forests in India and Southeast Asia. The International Union for Conservation of Nature (IUCN) has assessed it as a least-concern species.
The banded quail is a species of bird in the family Odontophoridae. It is found only in Mexico where its natural habitats are subtropical or tropical dry forests, subtropical or tropical dry shrubland, subtropical or tropical high-altitude shrubland, and heavily degraded former forest.
Perdicinae was a paraphyletic former subfamily of birds in the pheasant family, Phasianidae, regrouping the partridges, Old World quails, and francolins. Although this subfamily was considered monophyletic and separated from the pheasants, tragopans, junglefowls, and peafowls (Phasianinae) till the early 1990s, molecular phylogenies have shown that these two subfamilies actually constitute only one lineage. For example, some partridges are more closely affiliated to pheasants, whereas Old World quails and partridges from the Alectoris genus are closer to junglefowls. Due to this, the subfamily Perdicinae is no longer recognized by the International Ornithological Congress, with the species being split among 3 subfamilies.
Ikh Bogd Uul National Park is centered on Ikh Bogd, the highest mountain in the Altai-Gobi Mountains, a southeastern spur range of the Altai. The middle and high elevations feature alpine meadows and montane steppe. The range, with semi-arid deserts to the north and south, supports rare species, such as the near-threatened argali and Pallas's cat.
