Flying squirrels are a diverse group of nocturnal, arboreal rodents that are highly adapted for gliding locomotion. It is found in deciduous and mixed woods in the eastern half of North America, from southeastern Canada to Florida.Disjunct populations of this species have been recorded in the highlands of Mexico, Guatemala, and Honduras. [2][3] Various species have styliform bones to support the membranes, either on the elbow (colugos, anomalures, greater glider, Eomys) or on the wrist (flying squirrels). The patagium is a flap of skin forming a parachute-like extension of the body which catches air and allows the squirrel to glide. Flying squirrels, not quite concurring with their etymology, do not fly but are known for their unique ability to glide. 1. Living areas. The population of this species as a whole doesn't face any serious threats. The exact extent isn't clear, but they were extensive and supported by a long styliform bone as in gliding mammals.

They have a patagium, which is a specialized membrane that stretches from their wrists to their ankles. The patagium that stretches between an animal's hind limbs is called the uropatagium (especially in bats) or the interfemoral membrane. Southern flying squirrels are the only nocturnal members of the squirrel family in North America. The head and eyes are large, and a flap of skin, called a patagium, connects the front and rear legs.

In addition, they possess well-developed senses of smell, vision, hearing and touch. They can also turn 180 degrees. The preferred habitat of this species is woodland, dominated by maple, beech, hickory, oak, poplar and other seed-producing hardwoods.

The way the animal holds its long hindlimbs (referring here to the photo showing the animal from behind) and the suggestion of a patagium now make sense, and the unusual curving shape of the long tail matches the tail posture reported for giant flying squirrels (Meijaard et al. However, as males do not care for their young and typically leave before the litter is born, it may mean that this species exhibits either polygynous (one male mates with multiple females) or polygynandrous (promiscuous) (both males and females have multiple mates) mating systems.
