Details

Habitat

Its range is represented here by the Palearctic and the Indomalayan realm, where it uses forests, grasslands and freshwater habitats. Mobile species may shift habitat use with season, breeding sites, or food availability.

Appearance

Typical length 25-39 cm, weight 360 g-820 g. It has a long-bodied carnivore profile, with proportions shaped by its habitat and mode of movement.

Behavior

It is mostly active at night and usually solitary. Spacing, group size, and visibility can change with season, feeding conditions, and breeding activity.

Feeding

It is carnivorous. Food choice and foraging style are tied to life in forests, grasslands and freshwater habitats, so movements often follow available food resources.

Reproduction

As a mammal, it gives birth to live young, and the mother nurses them in cover or within the social group.

Notes

Recorded scientifically as Mustela sibirica. It remains widespread in parts of its range, but local habitat change still matters. In this guide, size, habitat, and activity pattern are useful first clues for recognition.
