Carolina chickadee
The Carolina chickadee (''Poecile carolinensis'') is a small passerine bird in the tit family Paridae. It is often placed in the genus ''Parus'' with most other tits, but mtDNA cytochrome ''b'' sequence data and morphology suggest that separating ''Poecile'' more adequately expresses these birds' relationships (Gill ''et al.'', 2005). The American Ornithologists' Union has been treating ''Poecile'' as distinct genus for some time already.
==Description==
Adults are long with a weight of , and have a black cap and bib with white sides to the face. Their underparts are white with rusty brown on the flanks; their back is grey. They have a short dark bill, short wings and a moderately long tail. Very similar to the black-capped chickadee, the Carolina chickadee is distinguished by the slightly browner wing with the greater coverts brown (not whitish fringed) and the white fringing on the secondary feathers slightly less conspicuous; the tail is also slightly shorter and more square-ended.
