Habitat and Ecology [top]

Habitat and Ecology: This species lives in areas with xerophytic vegetation, in rocks areas along canyon sides, around stone walls and corrals near ranches, and in agricultural areas.

It uses burrows that are made in open ground at the base of a tree or bush, in rocky areas along small ravines, or under mesquite. This species is an omnivore, and the dried and black seeds of Crescentia are an important part of its diet, as well as the fruits of plum trees.This species may cause significant damage to cultivated crops, such as corn, beans, and sorghum. It is possible that this species has spread its range into the more arid habitats of the Mexican Plateau because of the large areas under cultivation (Best 1995).
