Habitat
This species primarily inhabits arid deserts and semi-desert shrublands in the southwestern United States and northwestern Mexico. It prefers sandy or gravelly soils where it can dig burrows, often in open areas with sparse vegetation like creosote bush or mesquite. They are adapted to hot, dry conditions and avoid densely vegetated or mountainous regions.
Diet
Round-tailed ground squirrels mainly eat seeds, nuts, and green vegetation such as grasses and forbs, supplemented by insects like ants and beetles. They forage during the day, often storing food in their burrows for later use. Feeding activity peaks in the morning and late afternoon when temperatures are milder.
Behavior
These squirrels are diurnal and spend much of their time foraging above ground, but they retreat to burrows for protection and hibernation. They are generally solitary except during mating season, defending small territories around their burrows. Notable behaviors include estivation during hot summer months and torpor in winter to conserve energy.
Conservation Status
The IUCN status for the round-tailed ground squirrel is Least Concern, with a stable population trend due to its wide distribution. Major threats include habitat loss from urban development and predation by introduced species, but it is not currently facing significant decline.
