Distribution map of the white-tailed antelope squirrel—Ammospermophilus leucurus

The white-tailed antelope squirrel (Ammospermophilus leucurus), is a diurnal species of ground squirrel found in arid regions of the southwestern United States and the Baja California Peninsula of northwestern Mexico.

This species of squirrel has an average home range of 14.9 acres (60,000 m2), and utilizes approximately 4 acres (16,000 m2) in its daily activities.[2]

Ammospermophilus leucurus is omnivorous, feeding primarily on foliage (10%-60% of its diet), seeds (20%-50%), arthropods, and to a lesser extent, vertebrates (mainly lizards and rodents; predatory behavior by ground squirrels has been noted[3][4][5][6]).[7]
