Northern Flying Squirrel
Glaucomys sabrinus

Chipmunks, Squirrels, Ground Squirrels and Marmots
Squirrel Family (Sciruidae)

Measurement: Size: 30-31 cm Weight: 160-180 g

Description: Rarely seen, but quite common in low elevation coniferous forests, the northern flying squirrel is active only during the nighttime hours. They are gray above, with a slight reddish tinge to the back. The long tail is thickly haired, and almost as long as the body. Their eyes are big and dark, surrounded by the gray fur of the face. The underside is light. They fly by extending a thin, hair covered membrane of skin running between the front and rear legs. By stretching all four lets widely, the patagia (as this skin membrane is known) is spread tight, allowing the squirrel to glide long distances, in some cases, up to 45 m. They built two nests, one for summer, and the other for winter. The summer nest is built in the crook of a tree, and is a platform made largely of lichen and moss. They abandon this for an old woodpecker hole in winter, where entire family group huddles together to stay warm. They mate once a year, producing a single litter of three. They don't hibernate, but spend much of their time indoors waiting for the mercury to rise. They use their large eyes to find insects, birds eggs, nestlings, carrion, along with small amounts of seeds, fruits, fungi, and the buds of aspen, willow and alder.
