Prairie Warbler

The Prairie Warbler is a small wood-warbler of shrubby, early successional habitat across the eastern United States, despite its name having little association with open prairie grassland. It shows yellow underparts marked with black streaking, an olive back with chestnut streaks, and bold black facial markings, and is well known for its habit of frequently bobbing its tail while foraging.

The crown and back are olive-yellow with a patch of chestnut streaking on the upper back, most visible in breeding adults. Underparts are bright yellow with bold black streaking along the flanks, and the face shows a black eye-line and a black crescent below the eye. Wings show two faint yellowish wingbars. The combination of chestnut back streaking with yellow underparts and strong facial markings distinguishes it from other yellow warblers.

Breeding adults, especially males, show the most defined chestnut back streaking and boldest facial pattern. Females and immatures are duller, with reduced chestnut streaking and less contrasting facial markings. A single complete molt occurs after the breeding season.

Prairie Warblers breed in shrubby old fields, pine barrens, mangrove edges, and other early successional or scrubby habitat across the eastern United States. They winter primarily in the Caribbean and parts of Central America and southern Florida.

This species forages actively in low shrubs and small trees for insects, frequently bobbing or wagging its tail, a habit useful for identification even at a distance. The male's song is a distinctive ascending series of buzzy notes. Nests are built low in dense shrubs. It is a nocturnal migrant traveling to wintering grounds in the Caribbean and nearby regions.
