Discussion Colorful wood-warbler. Forages unobtrusively for insects, and silent birds are easy to overlook. Almost unmistakable but, confusingly, hybridizes with Golden-winged; two distinct hybrid forms occur ("Brewster's" and "Lawrence's" Warblers), males of which are fairly easy to recognize. Sexes are dissimilar.
