Habitat and Ecology

This squirrel occurs in deciduous and evergreen forest, semiarid pine-oak woodlands, and second growth (Reid 1997).

It is diurnal and mainly arboreal. It is most active in the early morning, but may be seen sunning on a branch later in the day. Nests of leaves and twigs are built on branches. It eats soft fruit, nuts, and seeds; when these foods are not available, it subsists on flowers, buds, and shoots. Females give birth during the dry season (April to August) and litter size is 2 to 3 young (Best et al. 1995; Reid 1997).

Justification

This species is listed as Least Concern in view of its wide distribution, presumed large population, occurrence in a number of protected areas, tolerance to some degree of habitat modification, and because it does not appear to be under threat and is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

Yucatan Squirrel

The Yucatan squirrel (Sciurus yucatanensis) is a tree squirrel in the genus Sciurus endemic to Belize, Guatemala, and Mexico.

These squirrels live in forests, active during the day and resting at night, spending most of their time in trees. Their dreys (or nests) are built in branches from leaves and twigs. The squirrel's main diet consists of soft fruit, nuts and seeds. Females generally give birth to 2 or 3 young during the April to August dry season.^[1]
