Yellow-rumped Warbler

Since 1973, American Ornithological Union has elected to merge these passerine birds as one species. The Myrtle and Audubon's forms were apparently separated by glaciation during the last ice age, and developed distinguishing physical characteristics. When it was shown, however, that they were able to interbreed, they were no longer considered as separate species. The two Middle American subspecies, goldmani and nigrifrons are sedentary and diverged from the northern migratory subspecies in the Pleistocene, and so probably represent separate species.

The Yellow-rumped Warbler is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.

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

Yellow-rumped Warbler is endemic to the highlands of Guatemala. It is a migratory bird which travels to Central America and the Caribbean for winters. Among warblers it is one of the last to leave North America in the fall, and among the first to return. It is an occasional vagrant to the British Isles and Iceland. More

Audubon's Yellow-rumped Warblers also have yellow throats. Females in breeding plumage have two white wing-bars. Males have a significant amount of white between the wing-bars. Males also have blacker breasts and grayer backs, and are generally much more brightly marked than females. Adults in non-breeding plumage are much duller in color, more brown than gray. In flight, white outer tail corners are noticeable. Immature birds are dull brown with yellow on their rumps and sides, but lack yellow on their throats and heads. More

no justification for the belief that the Yellow-rumped Warbler is a hybrid of the Myrtle Warbler and the Audubon's Warbler. Indeed, his research seemed to support the theory that the Audubon's Warbler appears to be subspecies of the Yellow-rumped Warbler. - Since 1973, American Ornithological Union has elected to merge these passerine birds as one species. These two forms were apparently separated by glaciation during the last ice age, and developed distinguishing physical characteristics. More

The yellow-rumped warbler is one of more than 25 warbler species found in North Dakota some time during the year. Yellow-rumped is the name given a warbler once known as two separate species. In 1973, the Ornithologists' Union decided birds previously known as Myrtle's and Audubon warblers were actually geographic representatives of one species, not two. More

It is no surprise that the yellow-rumped warbler is one of the most familiar warblers of North America; this bird is one of the first to arrive in the spring and the last to leave in the fall, and during the winter months it is the most abundant warbler in North America. While yellow-rumped warblers were formerly classified as two distinct species, today the Audubon’s and Myrtle warblers are both butter-butts. More

* The Yellow-rumped Warbler is one of the most common warblers in North America. * The eastern Myrtle and western Audubon forms were once considered separate species. Easily identified from one another, the Myrtle has a white throat, while the Audubon’s is yellow. More

yellow-rumped warbler (AKA butter butt), demonstrates that it is clearly the hardiest of the wood warblers—a group of birds not known for their toughness. Whereas most wood warblers winter in the tropics, myrtles can be found in the winter as far north as New Brunswick and the shores of the Great Lakes. More

Yellow-Rumped Warbler is a small songbird. In all plumages, it has whitish underparts with dark streaking, but Myrtle race has white or whitish throat strongly contrasting bright yellow rump and patch on sides of breast. It has usually a small yellow patch at centre of crown, boldly streaked blue-grey or grey-brown upperparts, and double white wing bars. It has white tail spots near tips. In summer plumage, the male is streaked on underparts forming blackish breast band. More

This Yellow-rumped Warbler was found at the University of Michigan-Dearborn from 15 to 17 May 1997, Leucistic Yellow-rumped Warbler by Allen Chartierwhen it was seen by many people, including those on field trips to the area during our International Migratory Bird Week celebration. It associated with a flock of other yellow-rumps, but those birds were somewhat antagonistic towards it. It often foraged close to the ground. More

The Yellow-rumped Warbler is a relatively new species created by lumping several subspecies, especially the eastern Myrtle Warbler (D. c. coronata), and the western Audubon More

The Yellow-rumped Warbler is one of the most common warblers in North America and the only warbler to regularly winter in Tennessee. It generally arrives in the state in late September and departs by mid-May. A couple of other warblers that migrate through the state have yellow rumps, but none of those rumps are as conspicuous. This distinctive yellow rump-patch has led birdwatchers to give it the affectionate name "butter-butt". More

now now that the Yellow-Rumped Warbler is a hybrid between these two slightly different types of warbler. These little birds are striking to look at. The give-away for identification is the flash of bright yellow you'll see in the rump area of the bird as it flies off. More

The Yellow-rumped Warbler is one of the most widespread and common warblers found in America. It is also one of the only warblers commonly found in northern parts of the country in winter. There are two sub-species of the Yellow-rumped Warbler, the Myrtle Warbler of the east and the Audubon's Warbler of the West. Description: The Myrtle Warbler measures about 5 1/2 inches in length.

The Yellow-rumped Warbler is the heartiest of the warblers of North America, some even spending the winter well north of Oklahoma. Here we see quite a few in wintertime (2007 OKC CBC—129 birds; 2008 OKC CBC—207 birds). Its diet in winter has been stated to include many types of berries, including cedar berries. Given the increasing prevalence of cedar trees on our landscape, I suspect that cedar berries are their primary food in winter in Oklahoma. More

Until recently, the Yellow-rumped Warbler was considered to be two separate but closely related species: Myrtle Warbler and Audubon's Warbler. Myrtle Warblers inhabit coniferous forests in summer from interior Canada across the taiga to Newfoundland and Labrador and south to northwest British Columbia; central Alberta; Saskatchewan and Manitoba; northern Minnesota, Wisconsin, and Michigan; New England, and northern Pennsylvania. They dislike deep forest interiors, preferring open woodlands and edge habitats. More
