Spermophilus erythrogenys

The red-cheeked ground squirrel has a stout, low-slung body supported by short legs and a well-furred tail measuring about a third the length of the body. It has internal cheek pouches for carrying food. The head, neck and body are varying shades of grayish brown and there is a reddish-ochre patch on the bridge of the nose.

The red-cheeked ground squirrel is distributed across the territory of the former Soviet Union, in Kazakhstan, Altai and Western Siberia, Mongolia and China (Xinjiang province). It inhabits steppes, forest-steppes, deserts and semi-deserts, favouring pastures, fallow lands, road sides and uncultivated land. In mountainous regions the species is found up to 2,100 metres (6,890 ft) above sea level.

Behaviour and daily activity varies greatly across the distribution range. Hibernation occurs in some areas and aestivation in others. This species is diurnal and feeds on the green parts of plants, seeds and roots. The burrows have permanent vertical entrances and temporary slanting ones. They are up to 2.8 metres (9 ft) in depth with the tunnels totalling up to 4.75 metres (16 ft). 100 holes and 15-20 individuals have been recorded on 1 hectare (2.5 acres). Reproduction rates vary depending on the weather conditions and are reduced during a prolonged cold spring. There are 2 to 12 young in a litter, typically 7 to 9. These ground squirrels are abundant and considered to be pests in parts of their range. They are hunted for meat and skins for local trade but their population is stable and adjudged to be of least concern in the IUCN Red List of Threatened Species.
