Predators of flying squirrels include tree snakes, raccoons, owls, martens, fishers, coyotes, bobcats, and feral cats. [3]
The northern flying squirrel (Glaucomys sabrinus) is one of three species of the genus Glaucomys, the only flying squirrels found in North America. [2] [3] They are found in coniferous and mixed coniferous forests across much of Canada, from Alaska to Nova Scotia, and south to the mountains of North Carolina and west to Utah in the United States.
The woolly flying squirrels are unique among the flying squirrels because of their large size and unique dentition. This led a few early researchers to go so far as to create a distinct family. Some of their arguments were based on poorly drawn and labeled diagrams of the cranium and lower jaw of E. cinereus.

Commonly referred to as the Old World flying squirrels, the genus Pteromys is distributed across temperate Eurasia, the Korean Peninsula and Japan. Although there are a host of flying squirrel genera in Asia (particularly southern Asia), Pteromys is the only one present in Europe .
A distinctive feature of flying squirrels is the furry glide membrane or patagium, a flap of skin that stretches between the front and rear legs. By spreading this membrane the flying squirrel may glide from tree to tree across distances of over a hundred meters, and have been known to record a glide ratio of 3.31, but is normally 1-1.5. [4]
