Notable for its running speed, the Texas Antelope Squirrel has the longest hindlimbs and tail of any antelope squirrel. In the field, the squirrels are noticeable because of the way they carry the tail arched forward over the back. This common inhabitant of the Chihuahua Plateau occurs in rocky habitats in desert mountain ranges, nesting in burrows or in between rocks and crevices, and eating various seeds, berries, and insects. Antelope squirrels do not hibernate--they are active year round.
