The rock ground squirrel is a large rodent from the squirrel family. It lives in rocky areas of the southwestern United States and is active during the day.
The rock ground squirrel differs from other ground squirrels in its mottled coloration and life among rocks. It helps spread plant seeds and serves as food for snakes, birds, and predators.
