The Blue-headed Vireo (Vireo solitarius) is a small songbird found in open mixed deciduous and coniferous woods throughout Canada east of the Rockies and the northeastern United States. In winter these birds migrate to the southern United States south to Central America.
Adults typically have olive upperparts, white underparts, yellowish flanks and white wing bars. Their head is grey with dark eyes ringed with white “spectacles.” They have a stout bill and thick blue-grey legs. This bird, along with the Cassin’s Vireo and Plumbeous Vireo, were formerly known as the Solitary Vireo.
Their bulky nest is suspended from a fork in tree branch. The male helps with incubation and may sing from the nest.
They forage for insects in the upper parts of trees, sometimes flying out to catch them. They will also eat berries on occasion, especially during the winter.
