Wilson's Warbler

Wilson's Warbler is a small yellow warbler with an olive back, a plain face and no wingbars. Adult males have a black cap, while females and young birds may show only a small dark crown patch or none at all. The species feeds actively on small insects in dense shrubs and low branches. It breeds across much of Canada and the western United States and winters from Mexico to Central America. It often uses moist vegetation along streams and forest edges.
