The tree squirrel is largely herbivorous, but also feeds on insects as most rodents do. They gather many small heaps of seeds around tree trunks and tufts of grass to aid tree regeneration. When eating, it uses its forefeet to handle food. As the name suggests, tree squirrels live in trees. They do, however, forage on the ground for a great portion of time. Territorial family groups sleep together in holes in trees at night and take shelter in trees when disturbed. To maintain their cohesive group dynamic, they groom one another to pass on a common scent. This is a pertinent element to their social structure. Males usually defend the group’s territory, but when tending to her dependent pups, females will also drive away trespassers.
