They keep warm in cold weather and have space to keep food. They are like small habitats for the squirrels to live. I chose to do the Virginia Northern Flying Squirrel because it is unique. It is one of not many types of flying squirrels. If it did happen to become extinct its natural predators like the bobcat could have a negative affect.
Many animals rely on it for food.
An interesting fact I learned about flying squirrels was that they have webbed feet and a piece of folded skin from wrist to ankle. When they jump from tree to tree they spread out their feet and the folded skin catches the air. This allows them to glide from tree to tree.
