What is "blue-headed vireo"

n. common vireo of northeastern North America with bluish slaty-gray head [syn: Vireo solitarius solitarius]

The blue-headed vireo (Vireo solitarius) is a Neotropical migrating song bird found in North and Central America. There are currently two recognized sub-species that belong to the blue-headed vireo. It has a range that extends across Canada and the eastern coast of the United-States, Mexico and some of Central America. It prefers large temperate forests with a mix of evergreen trees and deciduous under growth.

As the name suggests, the blue-headed vireo is characterized by its blue-grey head and bold yellow wing bars. Both sexes are very similar in plumage and size. Juveniles also have a similar plumage.

Populations of the blue-headed vireo have been steadily increasing since the 1970s and was therefore been classified as a " Least Concern" species in 2004.
