The abundant and widespread Yellow-rumped Warbler is not choosy about its wintering habitats. It was often considered to consist of two species, “Myrtle” (D. c. coronata) in the East, and “Audubon’s” (D. c. auduboni) in the West. Because they interbreed freely in a narrow zone of contact in British Columbia and Alberta, the American Ornithologists Union merged them. The two forms differ in plumage and voice, and their hybrid zone appears stable.

VOICE Myrtle’s call a flat, husky tchik; Audubon’s a higherpitched, relatively musical, rising jip; flight call of both a clear, upslurred sviiit; song loose, warbled trill with an inflected ending; Myrtle’s song higher and faster, Audubon’s lower and slower.

NESTING Bulky cup of plant matter in conifer; 4–5 eggs; 1 brood; March–August.

FEEDING Feeds mostly on flies, beetles, wasps, and spiders during breeding; takes fruit and berries at other times of the year, often sallies to catch prey.

FLIGHT: fast, slightly undulating, and direct with rapid wing beats.

WIDESPREAD WARBLER

Yellow-rumped Warblers are widespread and are likely to be spotted often.

OCCURRENCE

Both eastern and western populations are widespread across the continent from Alaska eastward to Québec and Labrador, and westward in the mountains south to Arizona, New Mexico, and Northern Mexico. Prefers coniferous and mixed hardwood coniferous forests.
