Northern Flying Squirrel (Glaucomys sabrinus)

Northern Flying Squirrels are expert gliders that use a skin-like membrane called the patagium to navigate their treetop homes. 

They typically live in mature, dense forests where they have access to a variety of food, including fungi, which they help to disperse by scattering spores. 

These squirrels also huddle in their nests to keep warm during cold temperatures.
