Carolina chickadee

This tiny, approachable bird has a short neck and large head, giving it a distinctive spherical body shape. Its tail is fairly long and narrow. Its bill is a bit thicker than a warbler’s but thinner than a finch’s.
Carolina Chickadees have a black cap and bib separated by stark white cheeks. The back, wings, and tail are soft gray.
They are inquisitive and acrobatic. Except in the breeding season, associates with other Carolina Chickadees and a variety of other small species in feeding flocks that roam within a fairly large area. Despite being a flocking species, they normally space themselves fairly widely while eating.
