The corsac fox is smaller than the red fox, with proportionately long legs and large, broad-based pointed ears. Its thick, soft upper fur is grey or reddish-grey with silvery tones, while the underside and chin are pale. The head and body measure 50–60cm, the tail adds 25–35cm, and average mass is about 2.7kg. Its broad ears help locate small prey moving beneath vegetation. (Animal Diversity Web)
This fox inhabits steppe and semi-desert from the lower Volga through Central Asia to Mongolia, Tibet and northern Manchuria, generally avoiding forests and dense thickets. It is mainly nocturnal in the wild and nomadic, sometimes moving south when deep snow restricts hunting. Rodents dominate its diet, supplemented by insects, pikas, birds and some vegetation. Corsac foxes often occupy marmot burrows and may share connected burrow systems in small family groups. (Animal Diversity Web)
