Habitat: The Blue-winged Warbler breeds in open shrubby habitats, woodland openings, edges of streams, willow swamps, and old fields with shrubs and small deciduous trees. Vegetation commonly consists of aspen, willow, maple, hawthorn, black locust, gray dogwood, and alder buckthorn, in early stages of succession. The habitat often includes low dense shrubs bordered by an open grassy area. The nest is built on the ground under a tussock of grass.

Habitat: Breeding: Edges of woods, bushy overgrown fields or borders of wooded swamps. Prefers old fields with saplings greater than 10 feet tall. Often near streams.

Special Habitat Requirements: Old fields with scattered shrubs and small trees.

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.

Diet: Insects and spiders. Details of diet not well known; probably feeds mostly on small insects, including beetles, ants, caterpillars, and grasshoppers, also spiders.

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.
