The red-eyed vireo is a small American songbird. It is somewhat warbler-like but not closely related to the New World warblers (Parulidae). Common across its vast range, this species is not considered threatened by the IUCN.
Region
North and South America
Typical Environment
Breeds widely across eastern and central North America, extending into southern Canada, favoring broadleaf and mixed woodlands. During migration and winter it occupies tropical lowland forests, second growth, and forest edges in northern and western South America, especially the Amazon Basin. It prefers mid to upper canopy strata, using edges, riparian corridors, parks, and large gardens with mature trees. Wintering birds readily use fruiting trees in semi-open habitats.

Adults have a distinctive red iris, while juveniles show brownish eyes. Its persistent, short-phrase song earns it the nickname 'preacher bird,' often sung from dawn to dusk. A common host of brood parasitism by Brown-headed Cowbirds in North America, it nevertheless remains very abundant.
