Habitat
Richmond's squirrel primarily inhabits oak-pine forests and mixed woodlands in the highlands of central and southern Mexico. They prefer elevations between 1,500 and 3,000 meters, where they nest in tree cavities or leaf nests. This species avoids open areas and dense urban environments, relying on mature trees for shelter and food.
Diet
Richmond's squirrel feeds mainly on acorns, pine seeds, and other nuts from oak and pine trees, which it gathers and caches for winter. They also consume fruits, berries, and occasionally insects or bird eggs, showing a preference for foraging in the early morning and late afternoon. Feeding behavior includes agile climbing and gnawing through tough seed shells.
Behavior
Richmond's squirrel is primarily diurnal, active during the day to forage and explore territories in trees. They are generally solitary but may share ranges with others of the same species, exhibiting territorial behaviors like chasing intruders from food sources. Notable behaviors include building leaf nests high in trees and performing warning calls when threatened.
Conservation Status
Richmond's squirrel is classified as Vulnerable by the IUCN due to habitat loss from deforestation and agriculture. Population trends are declining, with major threats including fragmentation of oak-pine forests and climate change.
