Habitat and Ecology [top]

Habitat and Ecology:It occurs in dry, deciduous forest, thorn scrub, and brush. It is often found among cacti and acacia, or along streams in otherwise dry areas (Reid 1997).

It is nocturnal, solitary, and terrestrial. The diet includes seeds (of Acacia, Ficus, Convolvulus, Liepenus, Prosopis, and Alicarpus), green plant material, and arthropods (spiders, beetles, crickets, and moths). Seeds about the size of garden peas are preferred. The relative proportion of vegetable and animal foods in the diet varies widely among different populations, which suggests opportunistic feeding (Alvarez et al. 1984, in Reid 1997). Breeding occurs almost year-round, except early in the dry season (Reid 1997).
Generation Length (years):2

Threats [top]

Major Threat(s): This species is threatened by the decline in deciduous forest habitat.

Conservation Actions [top]
