From atop trees, flying squirrels can initiate glides from a running start or from a stationary position by bringing their limbs under the body, retracting their heads, and then propelling themselves off the tree. The adult northern flying squirrel measures from 25 to 37 cm long, and their weight can range from 110 to 230 grams.įlying squirrels do not actually fly, they glide using a patagium created by a fold of skin. They can also be identified by their long whiskers, common to nocturnal mammals.

The Humboldt's flying squirrel was formerly considered conspecific, but was found to be a cryptic species, and now considered distinct. The northern flying squirrel is found in coniferous and mixed coniferous forests across the top of North America, from Alaska to Nova Scotia, south to the mountains of North Carolina and Tennessee and west to Utah. Unlike most members of their family, flying squirrels are strictly nocturnal. Except when they have young, they change nests frequently, and in winter a number of individuals may huddle together in a shared nest. They mostly breed once a year in a cavity lined with lichen or other soft material.
They feed on a variety of plant material as well as tree sap, fungi, insects, carrion, bird eggs and nestlings. They are proficient gliders but uncoordinated walkers on the ground. They are light brown with pale underparts and grow to a length of 25 to 37 cm (10 to 15 in).

Southern Flying Squirrels can make 90 degree turns while in flight and the maximum glide is up to 262 feet (80 meters).
