The invasive species is extremely harmful to its new environment. Another concern for the northern flying squirrel is the balsam woolly adelgid, a relatively harmless parasite of firs in Europe, which was unintentionally introduced to North America in the 1900s. The southern flying squirrel appears to be unimpaired by the parasite, however, because there’s a small overlap in the habitat of the northern and southern flying squirrels, the northern flying squirrel has been infected and this infection appears to be lethal. Declines in the southern Appalachians may be linked to Strongyloides Robustus, an intestinal parasite of southern flying squirrels. Fish and Wildlife Service, the Carolina Northern Flying Squirrel (fuscus) is endangered and the Virginia Northern Flying Squirrel (coloratus) is in recovery. Subspecies fuscus and coloratus of the Appalachian Mountains are both currently in a fragile state. As with many species who rely on forested ecosystems, Northern flying squirrels face the threat of invasive species, wildfires, climate change, and habitat loss due to land use practices, such as deforestation. The Northern flying squirrel can be found in Alaska, Michigan, California, West Virginia, Wyoming, Oregon, North Carolina, North Dakota, Utah, South Dakota, Vermont, Nevada, Idaho, New Jersey, New York, Montana, Wisconsin, Virginia, Pennsylvania, Ohio, New Hampshire, Minnesota, Maine, Washington, Massachusetts, and many regions of Canada. The species also occurs in the Blue, Ochoco, and Wallowa mountains”. According to the Oregon Department of Fish and Wildlife, the statewide presence of these squirrels includes “forested areas west of the Cascade Range and eastward to near Lakeview, Lake County, Paulina Lake, and Deschutes County. Their activity continues, even at low temperatures and in snow. Optimal conditions appear to be cool, moist, mature forest with abundant standing and down snags. Northern Flying Squirrels are nocturnal, but may occasionally be spotted during daylight hours. They take shelter in tree cavities, leaf nests, underground burrows, and abandoned nests of birds and other squirrels. Slight movements of the legs allow them to steer and that puffy tail acts as a brake. Instead, they have a membrane that extends from the wrist of the foreleg to the ankles of the hindleg, allowing them to glide from tree to tree without touching the ground. These flying squirrels aren’t actually capable of powered flight like a bird or a bat. They have gray-brown fur with gray-beige bellies, big black eyes, and pink feet. The northern flying squirrel has been observed to complete glides of over 130 feetĭespite their grace in the air, northern flying squirrels are clumsy when walking and will generally hide when caught on the ground.įlying squirrels are capable of making 90 degree turns while gliding, allowing them to maneuver around trees and other obstacles.The Northern flying squirrel is of the Sciuridae family and is the smallest arboreal (tree-living) squirrel in Oregon. Northern flying squirrels have been known to find and eat truffles, perhaps even remembering where they had been found previously Unlike other squirrel species, flying squirrels are entirely nocturnal, which maybe why you’ve never seen one Interesting facts about the Northern Flying Squirrel: The northern flying squirrel is a species of least concern, with healthy populations throughout North America. Northern flying squirrels do not actually fly, but are instead excellent gliders, using flaps of skin between their front and hind limbs to create “wings.” Flying squirrels either make a running start or launch themselves out of trees, using their skin flays to act as a glider with incredible maneuverability, then transitioning into a parachute shape to slow themselves for landings.Ī northern flying squirrel’s favorite food is mushrooms and fungi of all types, but they will also each tree sap, insects, bird eggs and carrion if necessary. The northern flying squirrel is usually a light brown or reddish color and average about 10-15 inches in length. Did you know that Idaho is home to the Northern Flying Squirrel ( Glaucomys sabrinus)? This unique mammal is native to much of Idaho, but as it prefers coniferous forests as its home, it is most commonly found in the northern parts of our state.
