| Espiritu Santo Island Antelope Squirrels live on a small, dry island covered with rocky hills and low mountains, a volcanic island that was connected to the mainland less than 10,000 years ago. Arid tropical shrubs and cactus grow on the lower slopes of the hills; the upper slopes are barren. A number of reptiles and a few other small mammals, including hares and rodents, are found on the island.
Antelope squirrels are diurnal. They usually dig their own burrows, though on the mainland, the closely-related White-Tailed Antelope Squirrel sometimes uses abandoned kangaroo rat burrows. They have internal cheek pouches that they use to carry food to their burrows or other sheltered hiding places. Their diets include plant parts, fruits, seeds, insects, and carrion. They are active even on the hottest days.
Antelope squirrels and Pronghorn Antelopes both flash the underside of their tails like white flags when they are running away. Thus the name.
