Field signs. It looks like a white kuropatku, but smaller. In winter, in males at the side of the head black stripes, summer dominated by gray in color, not red tone. Not shy and close bay Rights. Male Voice - hoarse shout, sounding like "krraad-kre-re-reee," it is not like the "laughter" white kuropatki (Syroechkovsky, Rogacheva, 1980). Weight - 400-550 g, 34-36 cm in length, wing 17,6-20,5 cm males, females - 17,5-19,5 cm, the magnitude of 54-60 cm (Ryabitsev, 2001)  Distribution. Obitatel and high mountain tundra. At the Taimyr with the highest density of the slot in the subzone typical (osokovo-moss) tundra (100-600 pairs per 100 km 2 of land) (Pavlov, 1974; Krechmar, 1966). In the Arctic tundra, according to the BM Pavlova (1974), its small size: 5-50 pairs per 100 km 2 of land. According NV Wronskians (1986), the arctic tundra of North-West Taimyr its strength may also be high: 125-520 pairs per 100 km 2. According to the survey, nest on the North earth: the on-ve Bolshevik, and possibly on other islands (Belikov, Randla, 1987). The southern border of regular nesting usually does not go beyond the typical sub-tundra (Vronsky, 1986). It runs approximately 71 ° N (middle reaches of the river. Pyasiny). In the shrub tundra is not solid. Then tundryanaya partridge in a small number again appears south in the highlands Putorana. Noted for its nesting in the area Hantayskogo lake. It may be that it breeds in the mountains of North Evenkia (Rogacheva, 1988). Typically, in north-western and central parts of the East Sayan, where the 1956-1960 biennium. the number of bird species was 4-6,2 / km 2 (Kim, 1991). Marked as a rare appearance for kustarnikovo-kustarnichkovyh formations in combination with vysokogornymi meadows, as a normal type of mountain tundra and rocks in scree West Sayan (Gavrilov, 1997). Studies last year showed that the number of tundryanoy kuropatki in the Sayan Mountains universally declined on average in 3-3,5 times. The highest rates were recorded in the density ranges Saylyg Khem-Taiga, a border plateau and Sai-Taiga - 2,8, 3 , 5; 7.2 animals / km 2 respectively (Gavrilov, 1999).
Phenology. Otkochevka begins in September. Females and males are kept separate gaggle all winter and only in the second half of March combined into a mixed gaggle (Syroechkovsky, Rogacheva, 1980).  Reproduction. In contrast to the white kuropatki for nesting is more sublime and the dry hilly areas of kochkarnikovyh and spotted tundra. In the second decade of June, took a pair of nest sites in the middle of the month beginning immure. Nest - shallow pit under the refuge of stone, a log or a bush, vystlannaya cloth with some feathers. In laying 6-12 light ohristyh with thick chocolate eggs krapom (more bright and yellow than the white kuropatki). In the first decade of August - has been flying chicks. By the end of the summer vyvodkah on Taimyr an average of 4.5 chicks (at the White kuropatki 7), which demonstrates the great loss of eggs and chicks mortality (Pavlov, 1974). Nutrition. In the winter diet, in contrast to the white kuropatki, has dominated Earrings and plumule alder (Syroechkovsky, Rogacheva, 1980). Chilennost. Usual number tundryanyh kuropatok about 5 times smaller than the number of white kuropatok (Syroechkovsky, Rogacheva, 1980).
