The range of the round-tailed ground squirrels often overlaps with the range of the Harris' antelope squirrels and the rock squirrels.

The round-tailed ground squirrel resembles a tiny prairie dog. However, apart from the resemblance and some similar habits with the prairie dog, the two species are not related. This group of species with the genus Spermophilus is strictly diurnal. Round-tailed ground squirrels have a long round tail complemented with long, broad, and hairy hind feet. The diet of these animals mainly consists of green vegetation. This diet of green vegetation includes spring wildflowers, cactus flowers and fruit, mesquite leaves, ocotillo flowers, and grasses. However, the species also has a diet of seeds and insects. As the habitat in the Sonoran Desert and all the other places lack water content, the diet of the round-tailed ground squirrel provides them with 80% of the water content they need.
