Vermivora cyanoptera
Conservation status | Despite being parasitized often by cowbirds, seems to be holding up well in numbers. May be gradually outcompeting and replacing the Golden-winged Warbler. |
---|---|
Family | Wood Warblers |
Habitat | Brushy hillsides, bogs, overgrown pastures, stream and woodland edges. Breeds in dry uplands in low shrubbery, brier patches, weed-grown fencerows, and bushy thickets; often in neglected fields or at the border of woods. Occasionally in deep swamp woods. |
Forages by moving about in shrubs and trees, often fairly low. Preferred method of foraging is by probing with bill into curled leaves. Also searches rather deliberately on outer tips of branches, perhaps probing into buds and flowers.
5, sometimes 4-7. White, with fine brown spots on larger end. Female incubates, 10-11 days. Young: Both parents feed nestlings. Young leave nest 8-11 days after hatching.

Insects and spiders. Details of diet not well known; probably feeds mostly on small insects, including beetles, ants, caterpillars, and grasshoppers, also spiders.
Hybridizes with Golden-winged Warbler. Hybrids, known as "Brewster's Warblers," are fertile, and they backcross with the parent species and with each other; second-generation hybrids include a rare type known as "Lawrence's Warbler." Males sing two types of songs, one in territorial interactions and one in courting a mate. Nest site is well concealed in grass or blackberry vines, sometimes under a bush or sapling, close to or on the ground. Attached to upright stems of grass or weeds, especially goldenrod. The bulky nest is a narrow, deep, inverted cone, usually built by the female alone. Constructed of dead leaves, grass, and beech or grapevine bark, and lined with plant fibers or animal hair.
Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.
Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.
Choose a temperature scenario below to see which threats will affect this species as warming increases. The same climate change-driven threats that put birds at risk will affect other wildlife and people, too.
