The yellow-rumped warbler (Setophaga coronata) has conspicuous yellow patches on the crown, flank, and rump in the breeding season. Both sexes are grey with flashes of white in the wings – males are very strikingly shaded; females are duller and may show some brown. Also known as the Audubon's yellow rumped warbler, it is is one of the most common warblers in North America. It is the only warbler able to digest the waxes found in bayberries and wax myrtles. Its ability to use these fruits allows it to winter farther north than other warblers, sometimes as far north as Newfoundland.
