Blue-winged Warbler

The Blue-winged Warbler (Vermivora pinus), is a fairly common New World Warbler. 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 is migratory, wintering in southern Central America. It is a very rare vagrant to western Europe, with one bird wandering to Ireland.

The breeding male Blue-winged Warbler is unmistakable. It is yellow above and below. The wings are gray with two white bars, and there is a black eye stripe. Females are duller, but otherwise similar. It is 4.5 inches long and weighs about 0.3 ounces (8.5g).

The breeding habitat is open scrubby areas. Blue-winged Warblers nest on the ground or low in a bush, laying 4-7 eggs in a cup nest. These birds feed on insects, and spiders. The song is a series of buzzing notes. The call is a sharp chip.
