Carolina chickadee

The famous naturalist John James Audubon named this acrobatic and gregarious songbird for its "chickadee-dee-dee" call. They eat mostly insects in the summer and seeds and berries in the winter. If it's really cold the Carolina Chickadee can go into a temporary state of hibernation called tupor. They'll hide in a tree cavity and lower their body temperature for up to 18 hours to conserve energy.
