Northern Flying Squirrel

Fascinating facts about the Northern Flying Squirrel

• A northern flying squirrel doesn't fly — it falls with style. Stretching a furry membrane called a patagium between its limbs, it can glide 150 feet (45 metres) from tree to tree, dropping just one foot for every ten feet forward. At the last second, it flicks its fluffy tail upright like a parachute brake and lands backwards on the trunk. In a single night, a flying squirrel can cover half a kilometre of forest floor by air alone, hunting in three dimensions while earthbound squirrels are still on the ground.
• Their eyes glow neon pink or red under ultraviolet light — a trick invisible to humans but obvious to flying squirrels themselves. New research suggests they can actually see in the UV spectrum, giving them a hidden light show in moonlit forests that we never knew existed. It might help them navigate, spot fungal fruiting bodies, or signal each other in the dark. Their night vision is 19 times sharper than ours.
• Mushrooms aren't a side dish for northern flying squirrels — they're the whole meal. In autumn they can consume nearly half their body weight in fungal fruiting bodies, then store the rest underground like tiny farmers. What they don't eat, they cache: a single squirrel can bury thousands of mushroom pieces across the forest floor. Many are never retrieved, sprouting as new mycelium networks that connect entire forests into a living underground internet of nutrient exchange.
• A mother flying squirrel raises her litters in a leafy drey — a basketball-sized nest built 40 feet high in spruce or fir trees. Newborns are born blind, hairless, and so small they weigh less than a gram. By eight weeks they're following their mother on gliding runs, learning to nail a perfect landing by crashing into trees over and over. Watching a juvenile's first flight is like watching a skydiver learn their lines — often messy, always determined.
• Logging has split their forests into islands, but flying squirrels still move between them. They'll glide across clearcuts and roads, sometimes misjudging and landing on pavement below. In the Pacific Northwest, spotted owls — their endangered cousins — depend almost entirely on flying squirrels for food. The fate of one is tangled with the fate of the other: conserving the squirrel's fragmented forest home is a lifeline for owls on the brink of extinction.

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.
