Northern Flying Squirrel (Glaucomys sabrinus) lives in forest across North American Temperate Forests. It feeds on mushrooms and nuts. Its conservation status is Least Concern.
Fascinating facts about the Northern Flying Squirrel
- Northern flying squirrels can zip between trees like living parachutes, typically covering 5 to 25 metres but once soaring a record 45 metres. Their glide angle averages 26.8 degrees with a glide ratio of 1.98, letting them glide shallowly and stay airborne longer. In the wild an average 'flight' is about 20 metres, yet some individuals have been clocked on flights as long as 90 metres, showing a remarkable span of aerial ability for a creature no bigger than a hand.
- When winter freezes the forest floor, northern flying squirrels huddle in shared nests of 4 to 10 individuals, turning a simple tree cavity into a living heat pack. This communal nesting is vital because they never hibernate or enter torpor; the body heat of the group keeps each squirrel warm enough to survive. The behavior illustrates how social cooperation directly buffers them against harsh northern climates.
- Fungi make up a major portion of the northern flying squirrel's diet, and they locate hidden truffles by scent. Researchers note they also use visual cues like coarse woody debris and remember past truffle sites, blending smell, sight, and memory to find these underground meals. This specialized foraging links the squirrels to forest health, as they help spread fungal spores that support tree roots.
- The northern flying squirrel occupies a continent-spanning belt of coniferous forests, from the treeline of Alaska and Canada down to northern California, Colorado, central Michigan, Wisconsin, and the Appalachian mountains of North Carolina and Tennessee.
- Northern flying squirrels usually raise a single litter of 2 to 4 pups each spring, but litters can be as small as one or as large as six, and in parts of southern Ontario they have been observed producing two litters per year. Most individuals live less than four years in the wild, so each breeding season is crucial for sustaining populations. Their short lifespan underscores the importance of successful reproduction each year.

About the Northern Flying Squirrel
In the shadowy realm of the forest, a whispered rumor of movement betrayed the presence of the Northern Flying Squirrel, its large, round eyes shining like moonlit pools as it navigated the darkness with an uncanny ease. With a gentle rustle of its silky fur, this nocturnal acrobat would launch itself into the void, its patagium - a membrane of skin that stretches from wrist to ankle - billowing like a parachute as it soared through the trees, a fleeting, ghostly apparition. As it glided, the forest floor below became a blurred tapestry, a kaleidoscope of textures and sounds that the squirrel navigated with a silent, effortless precision.
