In North America the name refers to members of the genus Citellus and sometimes to the closely related genera Tamias (chipmunk chipmunk, rodent of the family Sciuridae ( squirrel family). The chipmunk of the E United States and SE Canada is of the genus Tamias. The body of the common Eastern chipmunk, Tamias striatus, is about 5 to 6 in.

Other ground squirrel genera are found in Africa and S Asia. The approximately 30 North American species of Citellus are found W of Hudson Bay, from the Arctic Ocean to central Mexico. These ground squirrels have rounded heads, short ears and legs, and shorter, less bushy tails than tree squirrels. Their combined head and body length is 4 1-2 to 13 1-2 in. (11.4–33 cm) depending on the species; the tail is usually a third to two thirds as long. Most are gregarious, living in extensive underground burrows; they hibernate in colder parts of their range. Members of different species are found in prairie grasslands, arctic tundra, mountain meadows, open forest, desert, and scrub country. In some regions the ground squirrel is called gopher gopher or pocket gopher, name for the burrowing rodents of the family Geomyidae, found in North America and Central America. The gopher is gray, buff, or dark brown. Its combined head and body length is 5 to 12 in.

Primarily vegetarian in their diet, ground squirrels may become agricultural pests, but they destroy insects and mice as well as crops.

Any of numerous relatively short-legged, terrestrial rodents of the squirrel family (Sciuridae), found in North America, Mexico, Africa, Europe, and Asia. The name is often applied to chipmunks. Ground squirrels belong to the genera Ammospermophilus, Xerus, Atlantoxerus, and Spermophilus. They live in burrows, sometimes in colonies. Though primarily herbivores, some feed on insects and other small animals and on carrion. Many species collect food, carrying it in their cheek pouches, and store it in their burrows. Those in cold areas may hibernate in winter; those in dry areas may become dormant in summer. Species range from about 7 to 20 in. (17–52 cm) in length, including the tail.
