(from Wikipedia) The yellow-rumped warbler breeds from eastern North America west to the Pacific, and southward from there into Western Mexico. “Goldman’s” yellow-rumped warbler is a non-migratory endemic within the highlands of Guatemala and the black-fronted warbler is also a non-migratory Mexican endemic. The myrtle and Audubon’s forms are migratory, traveling to the southern U.S., Mexico, Central America, and the Caribbean for winters. Among warblers Audubon’s is by far the most widespread in North America in winter, and 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 and is an occasional vagrant to the British Isles and Iceland.
In summers, males of both forms have streaked backs of black on slate blue, white wing patches, a streaked breast, and conspicuous yellow patches on the crown, flank, and rump (the latter giving rise to the species’s nickname “butterbutt” among birdwatchers). Audubon’s warbler also sports a yellow throat patch, while the myrtle warbler has a white throat and eye stripe, and a contrasting black cheek patch. Females of both forms are more dull, with brown streaking front and back, but still have noticeable yellow rumps.
