High Quality Content by WIKIPEDIA articles! The Golden-winged Warbler, Vermivora chrysoptera, is a New World warbler, 11.6 cm long and weighing 8.5 g. It breeds in eastern North America, southeastern Canada and the eastern USA. 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.
