Notes: a beautiful warbler of scrubby deciduous forests; shows sexual dimorphism with the male having a black face patch and throat in addition to a bright yellow wing patch and crown; sometimes hybridizes with the Blue-winged Warbler to produce distinctive hybrids known as "Lawrence's Warbler" or "Brewster's Warbler", depending on the direction of the cross.
