|Habitat and Ecology:||This squirrel inhabits dense, tropical, deciduous forests, and is common in plains. Its burrows are on hillsides among rocks, and in sandy flats along walls and hedges bordering cultivated fields. It also occurs in the shade of the dense groves of oil palms (Arecaceae), with its burrows under masses of fallen palm fronds or sheltered by the thorny growth of mesquite (Prosopis) and catclaw (Acacia).
This squirrel eats fruits and nuts, and sometimes it also may feed on insects. Breeding occurs during the dry season (December to June). A female captured in February had four embryos (Best 1995).
|Major Threat(s):||No major threats are known to this species.|
|Conservation Actions:||A number of protected areas occur within its range.|
