squirrel

In the wild, eastern gray squirrels can be found inhabiting large areas of mature, dense woodland ecosystems, that generally cover 40 hectares of land. These forests usually contain large amounts of dense vegetation that provides sufficient amount of food sources and favorable shelters for eastern gray squirrels. Eastern gray squirrels generally prefer constructing their dens upon large tree branches and within the hollow trunks of trees. They also have been known to take shelter within abandoned bird nests. The dens are usually lined with moss plants, thistledown, dried grass, and feathers. These perhaps provide and assist in the insulation of the den, used to reduce heat loss. A cover to the den is usually built afterwards. Close to human settlements, eastern gray squirrels are found in parks and backyards of houses within urban environments and in the farmlands of rural environments.
