![]() 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. Yellow-rumped Warbler: The Yellow-rumped Warbler (Setophaga coronata) is a common yellow and black warbler, sometimes referred to by birders as the Butterbutt. Expect to see it any season except summer. Visit the north woods or middle elevation conifer forests of the West to find Yellow-rumped Warblers during summer. It is seen annually, from the northwestern areas of British Columbia, southward to the southern tip of. ![]() This is a hardy warbler and less likely to migrate over long distances, as other warblers do. Up to six inches, the black breast makes this warbler unique. There was a time when the Yellow-rumped Warbler (Audubon's) and the Yellow-rumped Warbler (Myrtle) were considered to be two different bird species. While Yellow-rumped Warbler reaches its highest densities in mature, unlogged coniferous forest habitat, it can do well in selectively logged forests where some mature trees are left standing. This bird may be seen year-round in Southern California Yellow-rumped Warbler This bird is more black than yellow, but it does have a distinctive yellow cap and throat. One of the last warblers to migrate in fall and one of the first to return in spring, remaining in northernmost breeding areas into October, and returning by late April. Western populations may winter near breeding grounds, primarily near Pacific Coast. Although it is confined largely to mature coniferous breeding habitat, individuals forage in a broad range of microhabitats and employ a variety of foraging techniques, from fly-catching to foliage-gleaning for insects. Among warblers, this species is also one of the most ecologically generalized. The Yellow-rumped Warbler is one of the most common warblers in boreal forest. The birds constantly chirp a "contact call" that keeps the flock together. ![]() During winter they disperse in loose flocks, and usually two or three birds at most are observed at a time. They most often sing from the high canopy of trees. ![]() Yellow-rumped Warblers are vivid and conspicuous birds that search for food both high and low in Douglas firs or pines. In the East, the "Myrtle Warbler" is an abundant migrant, and the only warbler that regularly spends the winter in the northern states. Until recently, the eastern and western populations of the Yellow-rumped Warbler were thought to be two distinct species, respectively the "Myrtle Warbler" and "Audubon's Warbler." However, it has been found that in the narrow zone where the ranges of the two come together, the birds hybridize freely. ![]()
