Vireos and their allies range widely over the Americas, from the boreal and temperate regions of North America, through the tropics of Central and South America, to the temperate woodlands of southern South America. They occur in northern Canada; throughout most of the United States, Mexico, and Central America; and in most of South America, as far south as Uruguay, northern Argentina, and northern Chile. Northern species of vireos are migratory, while those breeding in the tropics and subtropics are resident.
