Habitat and Ecology [top]

Habitat and Ecology:This squirrel occurs in most forested habitats including thorn scrub, deciduous and evergreen forest, dry pine-oak woodland, secondary forest, and plantations. In dry woodlands or forest it is most common, especially in those bordering agricultural areas (Reid 1997). It also occurs in urban areas.

This squirrel is diurnal and usually solitary. Individuals occupy distinct territories and may occur at densities of 0.7 individuals/ha (Coates-Estrada and Estrada 1986). It is mainly arboreal, but will come to the ground to feed or travel from tree to tree. Leaf nests are built on tree branches, 5 to 15 m above ground. In the lowlands, it feeds fruits and seeds of Ficus spp., Cecropia spp., Poulsenia armata, Brosimum alicastrum, and Astrocaryum mexicanum. Acorns and pine nuts are the staple foods of highland populations. Plantations of corn, mango, cacao, and tamarind are sometimes raided. It is usually silent, but sometimes makes raspy trills and harsh chatters. Females give birth to 2 to 4 young during the dry season; black and gray individuals may be born in the same litter (Reid 1997).
Generation Length (years):6
