Breeding.\u00a0 <\/em><\/strong>Breeds in bottomland swamps, Appalachian rhododendron thickets, and other humid woodlands with dense undergrowth in the southern tier of states from eastern Texas to northern Florida, and north to southern Missouri, southernmost Illinois, central West Virginia, and southeastern Virginia; with a small outpost population on the Delmarva Peninsula in Delaware and Maryland.<\/p>

Recent research indicates that Swainson\u2019s Warbler readily adapts to breeding in monoculture pine plantations, which are a significant and expanding use of land across much of its range (see Expansion of Swainson\u2019s Warbler Breeding Populations into Commercial Pine Plantations<\/strong><\/em> in Notes<\/strong><\/span>, below).<\/p>

Movements.<\/em><\/strong>\u00a0 A short-distance migrant that is seldom seen on migration\u2014evidently tends to fly nonstop between breeding and wintering grounds\u2014but is sometimes grounded in \u201cfall-outs\u201d at coastal sites such as High Island, Texas, and Dauphin Island, Alabama.<\/p>

Each year some individuals overshoot the breeding grounds and briefly attempt to establish territories.\u00a0 The most distant overshot records are from New Mexico, Colorado, Nebraska, Wisconsin, Ontario, and Massachusetts.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Identification<\/strong><\/span><\/p>

An inconspicuous, cryptically colored warbler with a remarkably long, pointed bill and flat-headed profile.\u00a0 Except when singing, it usually remains low in dense undergrowth or on the ground foraging in leaf litter.<\/p>

Olive-brown above, with a warm-brown or rusty cap, long, wide eyebrow, and dark eyestripe.<\/p>

Underparts are pale and may appear some combination of whitish, grayish, brownish, and yellowish; slightly darker on the sides.\u00a0 Its legs are pale pink.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
