Its main habitat, deciduous forest, is being deforested.

Habitat and Ecology [top]

Habitat and Ecology:This marsupial can be found in desert scrub, deciduous forest, and dry hills. It is semiarboreal and may spend more time on the ground than other mouse opossums. It is known to eat insects, figs, and probably cactus fruits. This species nests in dry leaves and stems, lined with plant down in forks of small trees and bushes (Wilson, 1991). Other nest sites include hollows in cacti or tree limbs, abandoned birds’ nests, and a single record of a nest among litter at the base of a fig tree (Armstrong and Jones, 1971). In western Mexico, the breeding season is from August to October, and litters of 8 to 13 have been recorded (Reid, 1997).

Threats [top]

Major Threat(s): There are no major threats, however, its main habitat, deciduous forest, is being deforested.
