The mountain weasel, also called the pale weasel or Altai weasel, is a small weasel of high, rocky country. Males are about 22–28 cm long with a 10–15 cm tail and weigh 230–340 g; females are slightly smaller. The summer coat is grey to grey-brown with some light yellow, and the winter coat is more of a dark yellow with brown. The underparts are pale yellow to cream, the head is darker between the muzzle and the ears, and the tail may be more rufous than the back (Wikipedia, general species account).
The Wikipedia account names Ladakh as the most common area for the species and says it is listed on Schedule II of India's Wildlife Protection Act, 1972. It rests in rock crevices, hollow trunks and burrows. It is mostly solitary and generally nocturnal, though it may hunt by day, and it climbs, runs and swims. Mating is usually in February or March, with young born around May, and it can delay implantation of the fertilised egg until resources allow (Wikipedia, general species account).
