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.
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.
