Some mammals continue to be active during the winter season.

The Eastern Chipmunk awakens from a lethargic, sleeplike state from February or March on.

The Red squirrel chooses the warmest moments of the day to venture outside its nest.

To better face the onslaught of cold weather, the Northern flying squirrels gather in groups.

-------------------------------------------------------------------------------------------------------------------------

Though they are usually solitary animals, American porcupines also gather together in cold weather.

The Snowshoe hare’s coat turns almost completely white in winter. Thus, the animal blends in with its snowy surroundings.

The White-tailed deer manages to find its food on the ground when the snow cover isn’t too deep. Otherwise, it feeds on twigs, bark, and buds.
