White belly and undertail coverts, white spectacles and whisker stripe. Largest North American Warbler. A harsh jumble of squawks, whistles, rattles. Nests in dense thickets and brush bordering deciduous forest.
Winter range is from coastal Mexico south into Central America, west to Panama.
Declining through much of the East and Midwest, probably due to decreased shrubland caused by urbanization and forest maturation. Western populations appear stable.
