Two squirrels in the entrance of a drey. Male and female squirrels may share the same nest for short times during a breeding season, and during cold winter spells squirrels may share a drey to stay warm. However, females nest alone when pregnant. In North America, squirrels produce broods of about three "pups" twice a year.
Tree squirrels live mostly among trees, as opposed to those that live in burrows in the ground or among rocks. An exception is the flying squirrel that also makes its home in trees, but has a physiological distinction separating it from its tree squirrel cousins: special flaps of skin called patagia , acting as glider wings, which allow gliding ...
Tree dens are preferred over leaf nests during the winter and for raising young. When den trees are scarce, leaf nests are used year-round. [16] [17] Leaf nests are built during the summer months in forks of deciduous trees about 30 feet (9 m) above the ground. Fox squirrels use natural cavities and crotches (forked branches of a tree) as tree ...
