Glaucomys sabrinus

Northern flying squirrels can be found in forested areas across northern North America. They use skin flaps to glide between trees. The trees in the forests must be close together for them to glide from one tree to another.

   Flying squirrels are nocturnal and use their large eyes to see in the dark. They den in tree cavities created by woodpeckers, carpenter ants, or wood rot.  Flying squirrels will eat a variety of food items including mushrooms, berries, lichen, spruce buds, and insects. Their primary predators include owls, hawks, and carnivorous mammals, such as martens.
