The Golden-winged Warbler, Vermivora chrysoptera, is a New World warbler, 11.6 cm long and weighing 8-10 g. It breeds in southeastern and south-central Canada and the Appalachian Mountains northeastern to north-central USA.

The Golden-winged Warbler, Vermivora chrysoptera, is a New World warbler, 11.6 cm long and weighing 8-10 g. It breeds in southeastern and south-central Canada and the Appalachian Mountains northeastern to north-central USA. The majority (~70%) of the global population breeds in Wisconsin, Minnesota, and Manitoba. Golden-winged Warbler populations are slowly expanding northwards, but are generally declining across its range, most likely as a result of habitat loss and competition/interbreeding with the very closely related Blue-winged Warbler, Vermivora cyanoptera.
Male has black throat; black ear patch bordered in white; yellow crown and wing patch. Females feature a smilar coloration pattern, but the black is replaced with light grey. In both sexes, extensive white on tail is conspicuous from below. Underparts are grayish white, bill is long and slender. Unlike most warblers, juveniles can be reliably sexed (using throat patch color) approximately 15 days after fledging.
