The southern flying squirrel (Glaucomys volans) is a rather interesting creature. It was with great amusement when one took up residence in a bird house in the backyard. The southern flying squirrel is a species of squirrel that is mainly nocturnal. It lives in the eastern part of the United States, parts of Canada, Mexico, and even parts of Central America. They measure 7 to 10 inches long and weigh between 1.6 and 2.5 ounces. That makes them about the same size as an eastern chipmunk (Tamias striatus) with half the weight. They eat mostly berries, nuts, seeds, and even insects. They do not hibernate but instead gather with other flying squirrels in the winter. They do not actually fly but instead glide with a membrane called a patagium that stretches between their legs like a sugar glider. They will use woodpecker holes or build nests or even use a bird house that is not in use as I found out. I hope to see and enjoy more of this fascinating creature.
