Facts about this animal

The Columbian ground squirrel is a typical souslik. It is mostly grey, underparts are yellow-orange. It has a bushy tail which has a length of 8-12 cm. Total length is 30-40 cm and it weights from 350 to 800 g, depending on season.

 

Columbian Ground Squirrels live in large colonies. Both males and females are territorial. Males defend a small core area within their home range, trying to keep other males from access to females. Females defend areas where their nest burrows are located. Both sexes mark their territories with scent glands located at the edge of the mouth, side of the head, and back.

 

Columbian ground squirrel hibernate for seven to eight months of the year and do not awake to eat stored food during their hibernation. The reproduction season is shortly after hibernation. After a gestation period of 24 days the female gives birth to, in May or June, to one litter of 2–7 young (average 3 or 4).

 

The Columbian Ground Squirrel eats a wide variety of food, including grasses, plant stems and leaves, seeds, bulbs and tubers, insects, birds and other small vertebrates. Especially when in large colonies, these squirrels sometimes damage grainfields.

Did you know?
That the Columbian Ground Squirrel feeds only for about 130 days a year? The rest of the year is spent in hibernation. The squirrel has to consume about 17 per cent of its body weight each day before going to sleep. Otherwise it wouldn't survive the winter.
