The Black-capped Chickadee has a black cap and bib with white sides to the face. Its underparts are white with rusty brown on the flanks and its back is gray. It has a short dark bill, short wings and a long tail. Males are larger. The tail is normally primarily slate-gray but has been observed in central New Jersey in 2008 to be completely white and seemingly longer and more prominent than the normal gray tail. At least one other such white tail has been observed as a documented change occurring in one individual (banded) bird..
