The golden-winged warbler (Vermivora chrysoptera) is a New World warbler. It breeds in southeastern and south-central Canada and the Appalachian Mountains northeastern to north-central United States. 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.
