White-tailed Antelope Squirrels reach sexual maturity by their first year and breed from February to June. Females typically have one litter per year, with sizes ranging from five to fourteen babies, depending on green vegetation availability, though they can occasionally produce two litters annually. The gestation period is about 30 to 35 days, and newborns are born hairless, with eyes and ears closed, weighing around three to four grams. They stay in a nest made of dry plant materials and animal fur for a few weeks before emerging and are weaned by around two months but may still rely on their mother’s care.

Their diet is quite varied, consisting of seeds, green vegetation like grasses and mesquite, fruits, invertebrates, and carrion.

Fun Facts

White-tailed Antelope Squirrels are skilled diggers and can quickly create complex burrow systems that provide shelter and protection from predators and extreme temperatures. Although they usually live alone, White-tailed Antelope Squirrels may share nests with other squirrels during harsh weather conditions, such as extreme heat or cold.
