A variant of the yellow-rumped warbler, The Audubon's warbler (Setophaga auduboni) has a yellow throat; in the Myrtle subspecies the throat is white. Male "Audubon's" Warblers have more white in the wing than the "Myrtle" Warbler. Female Audubon's have less distinctly marked faces, lacking the dark ear patches of the "Myrtle" Warbler. Audubon's warbler breeds in much of western Canada, the western United States, and into Mexico. It is migratory, wintering from the southern parts of the breeding range into western Central America.
