The yellow, unstreaked head and underparts and the black eyeline identify the Blue-winged Warbler. The Blue-winged Warbler occassionally hybridizes with the Golden-winged Warbler to produce offspring with characteristics of both parents. Some have mostly white underparts (Brewster's Warbler), while some have the yellow plumage of the Blue-winged but the dark throat of the Golden-winged (Lawrence's Warbler).
