Sable

The sable is a forest marten with an elongated head, prominent ears, and dense fur ranging from light brown to very dark brown. Its build is long and flexible, with relatively short legs and a well-furred tail. Coat shade varies geographically and individually, so darkness alone is not a secure field mark. It is an agile climber but usually searches for food using acute hearing and smell. The species account explicitly places its range from the Urals across Siberia into northern Mongolia, with adjoining occurrence in Kazakhstan, China, Korea, and Japan.

Sables are small omnivorous predators of northern forests. The opened account provides only a short biological summary, identifying skilled climbing and hunting guided mainly by sound and scent. Mating takes place between June and August, and litters normally contain two or three young. Broader range information reaches north to the tree line and south through the mountains of eastern Asia. Because the consulted source did not describe Mongolian diet, den sites, daily activity, or a named protected area, those details are not inferred from Russian or Japanese populations.
