Mustela sibiricaPallas, 1773, commonly known as the Siberian weasel, is a widely distributed Palearctic musteline with natural populations ranging from west of the Ural Mountains of Siberia to the Far East and south to Taiwan and the Himalayas. A key characteristic that distinguishes M. sibirica from most sympatric musteline species is the occurrence of a black mask on its face that surrounds the eyes, a white muzzle and chin, and the presence of a nearly completely monotone yellowish-brown coat. Although M. sibirica is hunted to make “kolinsky stable-hair” paintbrushes, populations remain stable and the species is currently listed as “Least Concern” by the International Union for Conservation and Nature and Natural Resources.
