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