Warblers- ORDER: Passeriformes
- FAMILY: Parulidae
Basic Description
Yellow-rumped Warblers are impressive in the sheer numbers with which they flood the continent each fall. Shrubs and trees fill with the streaky brown-and-yellow birds and their distinctive, sharp chips. Though the color palette is subdued all winter, you owe it to yourself to seek these birds out on their spring migration or on their breeding grounds. Spring molt brings a transformation, leaving them a dazzling mix of bright yellow, charcoal gray and black, and bold white.
More ID InfoFind This Bird
Visit the north woods or middle elevation conifer forests of the West to find Yellow-rumped Warblers during summer. They're often perched on the outer limbs of trees and are very conspicuous as they fly out after insects, often making long, aerobatic pursuits and flashing their yellow rumps and white patches in the tail. But the easiest time to see Yellow-rumped Warblers is probably on migration, when hordes of Yellow-rumped Warblers sweep down the continent, particularly along the Eastern Seaboard, where wax myrtles are abundant.

Backyard Tips
Yellow-rumped Warblers winter across much of central and southeastern U.S., and they sometimes come to backyards if food is offered. To attract them, try putting out sunflower seed, raisins, suet, and peanut butter. Find out more about what this bird likes to eat by using the Project FeederWatch Common Feeder Birds bird list.
- Cool Facts
- The Yellow-rumped Warbler 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.
- Male Yellow-rumped Warblers tend to forage higher in trees than females do.
- Yellow-rumped Warblers are perhaps the most versatile foragers of all warblers. They're the warbler you're most likely to see fluttering out from a tree to catch a flying insect, and they're also quick to switch over to eating berries in fall. Other places Yellow-rumped Warblers have been spotted foraging include picking at insects on washed-up seaweed at the beach, skimming insects from the surface of rivers and the ocean, picking them out of spiderwebs, and grabbing them off piles of manure.
- When Yellow-rumped Warblers find themselves foraging with other warbler species, they typically let Palm, Magnolia and Black-throated Green warblers do as they wish, but they assert themselves over Pine and Blackburnian warblers.
- The oldest recorded Yellow-rumped Warbler was a female at least 10 years old when it was recaptured and rereleased in Wyoming in 2006.
