About Blue-Headed Vireo
Small, sturdy songbird. Head bluish-gray with broad white eye-ring that extends as a stripe to base of bill; back bright olive-green; wings blackish with yellowish feather edges and two yellowish wingbars; underparts white; breast, sides and flanks yellow, sometimes with faint greenish streaks; blackish tail, whitish on outer feathers; legs and bill dark gray. Larger race found in Appalachians has a darker, grayer back and only the flanks are yellow.
They breed in the summer and spring. Both sexes build a cup nest of bark, roots, grasses, lichens, mosses, feathers, plant down and debris bound together with spider webs attached to twigs around the rim, lined with grasses, moss, hair or fur. They have 3-5 white eggs, sparsely spotted or speckled with brown, chestnut or black, that are incubated by both parents.
The Blue-Headed Vireo moves slowly through the trees as it looks for insects to eat. This species of bird does not migrate out of the United States during the winter months.
