Overview

Blue-winged Warbler: Medium-sized warbler with olive-green upperparts and yellow underparts. The head is yellow with thin black eye line and olive-green nape. Wings are dark gray with two white bars. When its range overlaps with the Golden-winged Warrbler, it often interbreeds with or displaces it.

Range and Habitat

Blue-winged Warbler: Breeds from Nebraska, central Iowa, southern Wisconsin, southern Ontario, and central New England south through east-central and Atlantic coast states to northern Georgia. Spends winters in the tropics. Preferred habitats include abandoned fields and pastures grown up to saplings; forest clearings and edges with clumps of catbrier, blackberry, and various bushes and young trees.

Breeding and Nesting

Blue-winged Warbler: Four to seven brown and gray flecked white eggs are laid in a grass-lined cup of dead leaves and fibers, and built on or very near the ground in thick undergrowth. Incubation ranges from 10 to 12 days and is carried out by the female.

Foraging and Feeding

Blue-winged Warbler: Diet consists of insects and spiders; forages in trees and shrubs.

Readily Eats

Bread Products, Sugar Water, Fruit, Nut Pieces

Vocalization

Blue-winged Warbler: Song is a buzzing "beeee buzzzz", with the second note lower and slightly trilled. A second song is more complex, consisting of buzzing notes followed by a variable number of short musical notes.

Similar Species

Blue-winged Warbler: Occasionally hybridizes with Golden-winged Warbler to produce offspring with characteristics of both parents. Some have mostly white underparts (Brewster's Warbler), while some have the yellow plumage of the Blue-winged, but the dark throat of the Golden-winged (Lawrence's Warbler).
