The white-tailed antelope squirrel is a small rodent native to the arid regions of the southwestern United States and northern Mexico. It typically measures about 8 to 10 inches in length, including its bushy tail. This squirrel has a distinctive white stripe along its sides and a white underside, which helps it blend into its desert surroundings. These squirrels are primarily active during the day and are known for their agility and speed. They feed on seeds, nuts, and insects, foraging in their habitat to find food. The white-tailed antelope squirrel plays an important role in the ecosystem by helping to disperse seeds and maintain plant diversity.
