Similar species: The Black-and-white Warbler is perhaps the easiest warbler to identify with its distinctive nuthatch-like feeding strategy and contrasting black and white plumage. The male Blackpoll Warbler is also black and white but lacks the white supercilium and doesn't creep along trunks and branches.
