Description

During the breeding season, the Myrtle race (see below) is dark with yellow patches on the crown, rump, and sides. During the non-breeding season, brown with a yellow patch visible on the rump and a yellow wash on the sides. All Yellow-rumped Warblers have a white belly, white or pale throat, a white eyebrow, and variable amounts of streaking on the breast and flanks. 14 cm (5.5 in) in length. There are two races, an eastern Myrtle race D. c. coronata and a western Audubon race D. c. audubonii. Since the Audubon race rarely occurs in the Southeast, this report addresses only the Myrtle race. The western Audubon race is darker overall with a yellow throat on the males.

Life Cycle

The breeding season begins in mid-April and extends to mid-June. The Yellow-rumped Warbler does not breed in the Southeast. Breeding habitat includes conifer woods, deciduous woods, open woods, and countryside with scattered conifers.The nest is usually found in a conifer from 1-15 m (4-50 feet) above the ground. The female builds the cup-shaped nest out of shredded bark, weeds, and other plant materials. The female lays 3-5 (usually 4-5) eggs that she incubates for 12-13 days. The young are altricial and fledge 10-12 days after hatching. Both the male and female feed the young, but only the female broods the young while they are in the nest.

Natural History

When not breeding, this species occurs in a variety of forested habitats, thickets, and overgrown fields or pastures. The diet of this species is primarily insects with some berries. The Yellow-rumped Warbler forages by searching among the vegetation for food and catching prey on the wing. This species migrates south for the winter. During migration and winter, these birds sometimes occur in large flocks.

Range

Yellow-rumped Warbler Region Map During the breeding season, the Myrtle race of the Yellow-rumped Warbler occurs in the extreme northern United States on the east coast. In the winter this species may be found throughout the southeastern United States and as far south as Central America. During this time, this species is common throughout the Southeast and is abundant in most of Georgia.

Conservation Status

This species is common in the winter and is not listed as Threatened or Endangered in any part of its southeastern range.

Similar Species

The Magnolia Warbler is similar to the Yellow-rumped Warbler. During the breeding season, the Magnolia Warbler has a gray crown, white eyebrow, yellow throat, and black sides of the face. It also has a yellow belly, black wings with white wing patches, a yellow rump patch, and a black tail. The streaking on the breast is more dominant in the Magnolia Warbler and can create a black ring below the neck. The completely yellow breast and belly is a key difference between the Magnolia Warbler and the Yellow-rumped Warbler.
