Yellow-Rumped Warbler in Fall Colors
Horicon Marsh Wisconsin
Four closely related North American bird 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)�are periodically lumped as the yellow-rumped warbler (Setophaga coronata).
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 endemic to the highlands of Guatemala. The Myrtle and Audubon's forms are migratory, traveling to the southern U.S., Mexico, Central America, and the Caribbean for winters.
Yellow-rumped warblers spend the breeding season in mature coniferous and mixed coniferous-deciduous woodlands (such as in patches of aspen, birch, or willow). In the western U.S. and in the central Appalachian Mountains, they are found mostly in mountainous areas. In the Pacific Northwest and the Northeastern U.S., they occur all the way down to sea level wherever conifers are present. During winter, yellow-rumped warblers find open areas with fruiting shrubs or scattered trees, such as parks, streamside woodlands, open pine and pine-oak forest, dunes (where bayberries are common), and residential areas.
