| Flying squirrels do not fly. They launch themselves into the air and glide long distances from tree to tree. They have a membrane known as a patagium that stretches between their front and hind limbs, which serves the same purpose as a hang glider's wings. The tail is flattened, which gives them an even greater gliding surface and aerial control. Northern Flying Squirrels play a critical role in the ecology of Pacific Northwest forests. They are important in the diets of Northern Spotted Owlsowl pairs are estimated to consume as many as 500 flying squirrels a yearand they help disperse the spores of fungi that aid the forest trees' absorption of nutrients from the soil.
