Mountain goose - endemic of the mountains of Central Asia to Russia comes only northern outskirts of its range. Field of habitat types studied are not sufficiently aware that it is the southern part of Tuva. Nest and separate breeding colony located in the border with Mongolia zone (Baranov, 1986, 1988, 1991).

Zalety mountain geese on the Taimyr, in Sayan and Minusinskuyu hollow, located north of nesting area, apparently taking place at the time of accession nepolovozrelyh individuals to stayam other birds in the wintering and how they can be flown (Borzhonov, 1978; Syroechkovsky, Rogacheva, 1995; Ptushenko, 1952) . It is possible that the distribution of species outside the main range bound and with increasing numbers in the Great Lakes Basin in Mongolia, where the bulk of the world population (Golovushkin, 1986). Habitats. Mountain goose occupies waters of desert, steppe, mountain-steppe landscape and intrazonalnyh (Syroechkovsky et al, 2000). Phenology. At Lake. Torah-Hol (South Tuva) in the spring of 1982, the first birds we observed on April 21 in 1989 - 19 April. The most intensive overflights of the area went in an easterly direction, with the last decade of April and first decade of May (14). Also in 1989 throughout May and early June kept from 9 to 43 animals. By the reproduction of birds starting in late April - early May (Baranov, 1986, 1988, 1991).

Reproduction. Gnezdyatsya they colonies of 3-7 nests, sometimes more, but found a pair of single nest on cliffs, tall trees or on the ground, in inaccessible locations.
