![]() In winter, this species may be found in open forest, thickets, and scrub as well as locally in urban and suburban areas. Yellow-rumped Warblers primarily breed in northern and high-mountain evergreen forest habitats. border south to Central America the western form also breeds locally in the mountains of Mexico and Guatemala. The western form breeds in the Pacific Northwest, the mountains of northern California, and in the interior west wintering in the southern California and the southwest. The eastern form of the Yellow-rumped Warbler breeds across Alaska, Canada, and at higher elevations in the northeastern United States wintering in the southeastern U.S., the Mid-Atlantic region, the Pacific coast from Washington to California, and the West Indies. This species may be distinguished from the similarly-patterned Magnolia Warbler ( Setophaga magnolia) by that species’ heavily streaked breast and broader tail. Females of both groups are duller and browner than the males, and all birds become dull brown above and pale below (while retaining the conspicuous yellow patches) during the winter. ![]() Summer males from the western (Audubon’s) group have more extensive black on the breast and a yellow throat, but are otherwise similar to eastern males. Summer males from the eastern (Myrtle) group are streaked gray above and white below with a black face mask, black breast, white chin, and conspicuous yellow patches on the head, wings, and rump. The yellow-rumped warbler ( Setophaga coronata) is a North American bird species combining four closely related forms: the eastern myrtle warbler (ssp coronata) 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).Ī medium-sized (5-6 inches) wood warbler, the Yellow-rumped Warbler occurs in two geographically-linked color groups.
