Animal Behavior of the California Ground Squirrel

The California ground squirrel, or Spermophilus beecheyi, is a large, bushy-tailed squirrel that is common to the Pacific Northwest. Its habitat ranges from southern California to central Washington.

Identification

The California ground squirrel measures 18 inches long, including its tail. It is mostly gray and brown, and has a speckled or spotted look.

Features

These squirrels are diurnal. In colder climates, they hibernate in winter and mate in spring, building nests in rocky outcrops.

Diet

The California ground squirrel mainly eats seeds, but will sometimes eat insects. When feeding, it stuffs food into pouches in its cheeks for later use.

Habitat

These squirrels live in underground burrows, and prefer to build them in open spaces. They inhabit well-grazed fields, hillsides, rocky outcrops and roadsides.

Communication

California ground squirrels use tail movements, scent production and vocalizations to communicate.

Fun Fact
