The Tibetan snowcock (Tetraogallus tibetanus) is a bird in the pheasant family Phasianidae of the order Galliformes, gallinaceous birds. This species is found in high-altitude regions of the Western Himalayas and the Tibetan Plateau, where it overlaps in part with the larger Himalayan snowcock. The head is greyish and there is a white crescent patch behind the eye and underside is white with black stripes. In flight the secondaries show a broad white trailing edge.
Smaller than Himalayan snowcock, this species has a grey head and neck with a white patch behind the eye and above the dark cheek. Chin, throat and breast are white, with two grey bands on the breast. Grey wing coverts and tertials have a white trim. The secondaries have a broad white trailing edge that forms a wing band. Underparts are white with black streaks on flanks and belly. The tail is rufous brown and the undertail coverts are black. Legs and beaks are reddish. Sexes are similar, but female has buff in postocular patch, blackish and buff marks on sides of head, neck and breast-band, and lacks the tarsal spurs of the male.
The widely distributed populations show variations in plumage and about five subspecies have been designated:
Some races such as tschimenensis and yunnanensis are not widely recognized, the former included in the nominate form.The genetic divergence of these populations has been attributed to glacial cycles associated with the uplift of the Tibetan plateau.
Tibetan snowcock are found on alpine pastures stony ridges above the tree line in the Pamirs of Tajikistan, Himalayas (from Ladakh to Arunachal Pradesh), Tibet and China.They are found in lower altitudes during winter or when there is heavy snowfall. In parts of its range there appears to be a clear separation of the distribution of this and the Himalayan snowcock while in others they appear to overlap.
Since the Tibetan snowcock has a large distribution range and no visible declines in population, it has been considered a species of "least concern" by the IUCN.
This species is similar to the Himalayan snowcock, but prefers higher altitudes. During winter, they descend to lower altitudes and move around in coveys. When approached from below on a hill slope, they move up, stopping every now and then to look at the intruder, but when alarmed they fly away downwards crossing the valley/ravine. The flight is swift and will often make a whistling call in flight. They call several times while alighting and on settling from flight they shake their tails several times in the manner of willow ptarmigan. They call in the morning and evening, becoming quiet in the middle of the day.They keep to grass-covered plateaus and ridges or to the more barren and stony plains with very little vegetation. Though they do not keep sentries during feeding, while resting in the middle of the day, one or more of adult birds mount high boulders and keep a watch, warning the flocks on the approach of danger with loud prolonged whistles. Several calls have been described that include a chuckling that gradually becomes louder, a whistle and a curlew-like call.
During summer, they form pairs and males are believed to be monogynous. The nest is a scrape, sparsely lined and sheltered under a stone or bush usually on the leeward side of a bare hill, and avoiding ground with vegetation. About 4 to 6 eggs are laid. The male stands sentinel while the females incubate. Both parent birds accompany the brood and adults perform distraction displays when the young are threatened, while the chicks crouch or hide between stones. Broods of more than one female have been found to form a single foraging group.
The Himalayas, or Himalaya, , is a mountain range in Asia separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has many of Earth's highest peaks, including the highest, Mount Everest, at the border between Nepal and China. The Himalayas include over fifty mountains exceeding 7,200 m (23,600 ft) in elevation, including ten of the fourteen 8,000-metre peaks. By contrast, the highest peak outside Asia is 6,961 m (22,838 ft) tall.
The Himalayan vulture or Himalayan griffon vulture is an Old World vulture native to the Himalayas and the adjoining Tibetan Plateau. It is one of the two largest Old World vultures and true raptors. It is listed as Near Threatened on the IUCN Red List.
The Tibetan Plateau, also known in China as the Qinghai–Tibet Plateau or the Qing–Zang Plateau or as the Himalayan Plateau in India, is a vast elevated plateau in Central Asia and East Asia, covering most of the Tibet Autonomous Region, Northwestern Yunnan, Western half of Sichuan, Southern Gansu and Qinghai provinces in Western China, Indian regions of Ladakh and Lahaul and Spiti as well as Bhutan. It stretches approximately 1,000 kilometres (620 mi) north to south and 2,500 kilometres (1,600 mi) east to west. It is the world's highest and largest plateau, with an area of 2,500,000 square kilometres (970,000 sq mi). With an average elevation exceeding 4,500 metres (14,800 ft) and being surrounded by imposing mountain ranges that harbor the world's two highest summits, Mount Everest and K2, the Tibetan Plateau is often referred to as "the Roof of the World".
The blood pheasant is the only species in genus Ithaginis of the pheasant family. It is a relatively small, short-tailed pheasant that is widespread and is fairly common in eastern Himalayas, ranging across India, Nepal, Bhutan, China and northern Myanmar. Since the trend of the population appears to be slowly decreasing, the species has been evaluated as Least Concern by IUCN in 2009.
The cheer pheasant, also known as Wallich's pheasant, is a vulnerable species of the pheasant family, Phasianidae. It is the only member in the genus Catreus. The scientific name commemorates Danish botanist Nathaniel Wallich.
The Tibetan sandgrouse is a large bird in the sandgrouse family. The genus name Syrrhaptes is from Ancient Greek surrhaptos, "sewn together" and tibetanus is from the type locality, Tibet.
The snowcocks 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 Himalayan monal, also known as the Impeyan monal and Impeyan pheasant, is a pheasant native to Himalayan forests and shrublands at elevations of 2,100–4,500 m (6,900–14,800 ft). It is part of the family Phasianidae and is listed as Least Concern on the IUCN Red List. It is the national bird of Nepal, where it is known as the danphe or danfe, and state bird of Uttarakhand, India, where it is known as the monal. It was also the state bird of Himachal Pradesh until 2007.
The Tibetan partridge is a gamebird in the pheasant family Phasianidae of the order Galliformes. They are found widely across the Tibetan Plateau and have some variations in plumage across populations. They forage on the ground in the sparsely vegetated high altitude regions, moving in pairs during the summer and in larger groups during the non-breeding season. Neither males nor females have spurs on their legs.
Hemis National Park is a high altitude national park in the eastern Ladakh Union Territory of the Republic of India. Globally famous for its snow leopards, it is believed to have the highest density of them in any protected area in the world. It is the only national park in India that is north of the Himalayas, the largest notified protected area in India and is the second largest contiguous protected area, after the Nanda Devi Biosphere Reserve and surrounding protected areas. The park is home to a number of species of endangered mammals, including the snow leopard. Hemis National Park is India's protected area inside the Palearctic realm, outside the Changthang Wildlife Sanctuary northeast of Hemis, and the proposed Tso Lhamo Cold Desert Conservation Area in North Sikkim.
The snow partridge is a gamebird in the pheasant family Phasianidae found widely distributed across the high-altitude Himalayan regions of India, Pakistan, Nepal and China. It is the only species within its genus. The species is found in alpine pastures and open hillside above the treeline but not in as bare rocky terrain as the Himalayan snowcock and is not as wary as that species. Males and females look similar in plumage but males have a spur on their tarsus.
The flora and fauna of Ladakh was first studied by Ferdinand Stoliczka, an Austrian Czech palaeontologist, who carried out a massive expedition in the region in the 1870s. The fauna of Ladakh have much in common with that of Central Asia generally, and especially those of the Tibetan Plateau. An exception to this are the birds, many of which migrate from the warmer parts of India to spend the summer in Ladakh. For such an arid area, Ladakh has a great diversity of birds — a total of 318 species have been recorded. Many of these birds reside or breed at high-altitude wetlands such as Tso Moriri.
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.
The Altai snowcock 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.
Perdicinae is a 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.
The Northeastern Himalayan subalpine conifer forests are a temperate coniferous forests ecoregion of the middle to upper elevations of the eastern Himalayas and southeast Tibetan Plateau. The ecoregion occurs in southeastern Tibet Autonomous Region, China, in northern and eastern Arunachal Pradesh, India, and extreme eastern Bhutan.
Organisms can live at high altitude, either on land, in water, or while flying. Decreased oxygen availability and decreased temperature make life at such altitudes challenging, though many species have been successfully adapted via considerable physiological changes. As opposed to short-term acclimatisation, high-altitude adaptation means irreversible, evolved physiological responses to high-altitude environments, associated with heritable behavioural and genetic changes. Among animals, only few mammals and certain birds are known to have completely adapted to high-altitude environments.
Przevalski's nuthatch, originally given the nomen nudum"Sitta eckloni", is a bird species in the family Sittidae, collectively known as nuthatches. Long regarded as a subspecies of the white-cheeked nuthatch, it nevertheless differs significantly in morphology and vocalizations. Both S. przewalskii and S. leucopsis have been regarded as closely related to the North American white-breasted nuthatch. It is a medium-sized nuthatch, measuring about 13 cm (5 in) in length. Its upper body is a dark gray-blue or slate color, becoming dark blue-black at the crown. The cheeks and throat are a white buff-orange, turning to a rich cinnamon on the underparts that intensifies in color on the sides of the breast. Vocalizations consist of alternating series of ascending whistles and short notes.
