Black-Capped Chickadee Poecile atricapilla
Black-capped Chickadees are constantly on the move, often hopping around and hanging upside-down from twigs or branches while searching for insect eggs and larvae. Chickadees often associate in small flocks. The chickadees distinct "chick-a-dee-dee" call is one of the most complex vocalizations in the animal kingdom.

Chickadees also use their call to relay information about an individual's identity or to indicate that they recognize a particular flock.
