Priority Bird

Golden-winged Warbler

Vermivora chrysoptera

A strikingly patterned warbler of leafy second growth and swamp edges. Once common in the northeast, it has been declining recently in southern parts of its breeding range. As it disappears, its close relative the Blue-winged Warbler has been advancing north. The Blue-wing may be driving the Golden-wing out of the best habitats, but the situation is not well understood. The two species interbreed, creating distinctive hybrid types known as "Brewster's" and "Lawrence's" warblers.
Conservation status Increased and expanded range in late 1800s, probably as clearing of forest created more of the second-growth habitat favored by this species. Now declining seriously in southern part of breeding range. Competition and interbreeding with Blue-winged Warbler probably part of cause, also parasitism by cowbirds.
Family Wood Warblers
Habitat Open woodlands, brushy clearings, undergrowth. Breeds in brushy areas with patches of weeds, shrubs, and scattered trees (such as alder or pine). This habitat type is found in places where a cleared field is growing up to woods again, as well as in marshes and tamarack bogs. In winter, in the tropics, lives in forest edges and open woodland.

Feeding Behavior

Forages mostly in the upper level of trees and shrubs in summer. Feeds by probing and picking among foliage, sometimes hanging head downward. Probes in curled leaves and pries them open in search of insects. May forage with Black-capped Chickadees on breeding territories and in migration. On wintering ground, mainly feeds fairly low in trees, in mixed flocks with other species.


Eggs

5, sometimes 4-7. Pale cream or pink with streaks and blotches of brown and lilac. Incubation by female, 10-11 days. Up to 30% of nests have cowbird eggs. Hatching of warbler eggs is low when cowbirds present, but cowbird nestlings do not necessarily fare better than the warbler nestlings. Young: Leave nest after 8-9 days, are fed by parents for up to another month. Parents may divide fledglings into two groups, each parent attending only part of brood. 1 brood per year.

Diet

Mostly insects. Diet is not known in detail, but feeds on many caterpillars and adult moths, especially Tortricid moths, also other insects and spiders.


Nesting

Hybridizes with Blue-winged Warbler. Male arrives on territory in May, a few days before the females. Male defends territory by singing; in aggressive encounters, he postures with raised crown feathers and spread tail, and he may chase and fight with other males. Males have two song types, one used to advertise territory and one mostly for attracting a mate. Courtship includes male chasing female, raising his crown feathers, slow wing beats as male flies away, and gliding flight as male flies toward female. Nest: Built by female on the ground at base of shrub or in a tussock of grass or sedge, usually hidden by foliage. Open cup nest constructed of leaves, grapevine bark, and long strips of grass; lined with fine plant material.

Migration

Migrants are seen most commonly in late April and May, and during September. Probably migrates mostly at night.
