Brewsters Warbler

The Golden-winged Warbler hybridizes extensively with the Blue-winged Warbler, giving rise to the distinctly plumaged "Brewster's" and "Lawrence's" warblers. Brewster's looks like a Blue-winged Warbler with a white chest, and Lawrence's looks like an all-yellow Golden-winged Warbler. Backcrosses of hybrids to pure parental types result in many intermediate-appearing birds.
