Description
Brandt's ground squirrel is smaller than most other Spermophilus species being 165 to 210 millimetres long with a short tail some 30 to 50 millimetres long and weighing up to 440 grams. It is an ochre brown colour with distinctive lighter coloured spots. The hind feet are russet as is the tail, though in some parts of the range the tail is yellowish. There are paler regions around the eyes with rust coloured patches above and below.[5]
Biology
This species is found in dry steppes and semi-desert brushlands. It lives either communally or singly in burrows where it hibernates in winter and aestivates in excessive summer heat. The entrance to the burrow is often found at the base of a bush. The diet is primarily vegetarian consisting of seasonal plant growth[6] including young shoots of certain shrubs, bulbs and tubers. Unlike some other related species, Brandt's ground squirrel seldom stands erect on its two hind legs and its alarm cry is a quiet squeak.[5]
