Four closely related North American bird forms—the eastern myrtle warbler [ssp coronate], its western counterpart, Audubon’s warbler [ssp group auduboni], the northwest Mexican black-fronted warbler [ssp nigrifrons], and the Guatemalan Goldman’s warbler [ssp goldmani]—are periodically lumped as the yellow-rumped warbler [Setophaga coronate].
The yellow-rumped warbler breeds from eastern North America west to the Pacific, and southward from there into Western Mexico. Among warblers it is by far the most widespread in North America in winter, in the northern and central parts of the continent, it is among the last to leave in the fall and among the first to return.
These birds are one of North America’s most abundant neotropical migrants. They are primarily insectivorous. The species is perhaps the most versatile foragers of all warblers. Beyond gleaning from leaves like other New World warblers, they often flit, flycatcher-like, out from their perches in short loops, to catch flying insects.
