The thirteen-lined ground squirrel is a small rodent with characteristic stripes on its back. It lives in the prairies of North America, digs burrows, and hibernates in winter.
The thirteen-lined ground squirrel differs from other species by its distinct thirteen stripes on the back. It is important for nature as food for predators and as an animal that loosens the soil and disperses seeds.
