Ecological Features
The Siberian weasel is a small mammal commonly found throughout various regions, particularly in rocky forested areas and mountain valleys. During winter, it often moves closer to human dwellings, residing in barns or taking shelter in crevices between stones, under roots, or in hollowed-out trees. Its diet varies depending on the environment, but it primarily feeds on insects, crustaceans, fish, reptiles, birds, and small mammals during summer. It may also consume fruits when available.
General Characteristics
The Siberian weasel has a long, slender body with short legs. Males are generally larger than females. In winter, its fur becomes longer, and its upper body, limbs, and tail display a yellowish hue. The forehead turns dark brown, while the cheeks and underbelly have a rich ochre color. Its toes are webbed, and it has glands near the anus that emit a strong odor for defense.
