 Blue-winged Warbler





Warblers, with their brilliantly colored feathers, are the tiny jewels of Ohio's bird families. They are very active - constantly flittering around. Most are yellow with black-and-white markings. Their plumage varies considerably from spring to fall, juvenile to adult, and male to female. The tail is square, often with white markings. Warblers feed almost entirely on insects gleaned from leaves and twigs with their slender bills. Members of this family abound in any Ohio woodland or brushy area during the spring and fall migration seasons. In spring their buzzlike songs (not warbling) fill the air with a delightful chorus.

Description
The face and underparts of this warbler are yellow, and the the wings have two white bars. A distinguishing characteristic is the black line through the eye.

Habitat and Habits
The blue-winged warbler occupies abandoned fields and cutover hillsides dominated by shrub-sapling stage vegetation, brushy woodland clearings, and the shrubby margins of woods. They generally avoid fencerows and other narrow brushy corridors bordered by open fields. This species prefers moist thickets, but will also occupy relatively dry hillsides. Its song is a very buzzy, distinctive beee-buzzzz! that is fairly unmistakable.

Reproduction and Care of the Young
In Ohio, nest construction is most prevalent during May. Nests with eggs can be found during late May and early June and the young usually fledge in late June or early July.
