Antelope Ground Squirrel (Ammospermophilus leucurus)
Whitetailed antelope squirrels are found at desert and submontane elevations, preferring rocky or gravelly soil. Their population trend is stable. They burrow beneath shrubs, trees, or rocks. Five to 14 young are born in early spring and occasionally a second litter occurs. These solitary mammals are active all year, although some may hibernate. They forage on the ground and sometimes in cacti for seeds and fruit. The home range size of these nongame animals is 14-20 acres.
