Tiny, plump-bodied, big-headed bird is a familiar woodland resident and backyard visitor in the northern U.S. and Canada. Gray overall with buffy flanks and a contrasting head pattern: black cap, white cheek, and black throat. Short, stubby bill is used for hammering open seeds. Often the core of mixed flocks of songbirds. Visits feeders. Nearly identical to Carolina Chickadee, but note voice and range.
