Description

Typical adults are about 30 centimetres (12 in) long. Weights vary greatly with time of year and with location: at emergence from hibernation the squirrels weigh between 200 and 275 g (0.441–0.606 lb) for females and between 350 and 450 g (0.77–0.99 lb) for males. But by the time they hibernate again, their weight may have risen to nearly 750 grams (1.65 lb). Males are slightly larger and heavier than females on average. They are dark brown on the upper side and tan underneath. The tail is shorter and less bushy than in other ground squirrels, and the external ears are so short as to look more like holes in the animal's head. Behavior is more like that of a prairie dog than a typical ground squirrel. The tail is constantly trembling, so the animal is sometimes called the "flickertail". Males have an average life expectancy of 3 years, while females average 4 years. However, in captivity some individuals may live for 5 to 7 years.
