Flying squirrels are entirely nocturnal, inhabiting mature forests and parks, as well as other woodlands. They utilize the many cavities that are found in mature trees for nesting and winter denning. Unlike bats, flying squirrels do not really fly. They have a loose membrane of furred skin attached between their front and back legs. The membrane helps these squirrels glide from tree to tree.
Flying squirrels readily visit bird feeders. One way to view these creatures after dark is to use a red light to illuminate the feeder. The red light does not bother the feeding squirrels but allows you to see their activity after dark.

The question for researchers is why it seems that the northern flying squirrel population is retreating while the southern flying squirrel is increasing. Some evidence suggests that the continued existence of the northern flying squirrel in the Lower Peninsula is at risk.
