Golden-winged Warbler

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 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.
