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