Blue-winged Warbler

The Blue-winged Warbler (Vermivora cyanoptera) is a fairly common New World warbler, 11.5 cm long and weighing 8.5 g. It breeds in eastern North America in southern Ontario and the eastern USA. Its range is extending northwards, where it is replacing the very closely related Golden-winged Warbler, Vermivora chrysoptera. It was formerly called Vermivora pinus, but this name is invalid, as it was given after descriptions of this species and the Pine Warbler.

It is migratory, wintering in southern Central America. It is a very rare vagrant to western Europe, with one bird wandering to Ireland.
