This vireo has been one of the most abundant birds in North America, although its numbers seem to have declined recently, possibly as a result of the destruction of wintering habitat in the neotropics, fragmentation of northern breeding forests, or other causes. Its principal habitat, broad-leaved forests, often supports one pair per acre. A persistent singer during the breeding season, the Red-eyed Vireo utters its endless series of short phrases from dawn till dusk, even on the hottest days when other birds are silent, and may even sing while grappling with the large insects it captures. The Red-eyed Vireo is a fierce fighter around its nest and can intimidate even the large Pileated Woodpecker. Its horizontal posture and slow movement through the understory of broad-leaved woods make it an easy bird to study.


3 or 4 white eggs, sparsely marked with dark brown, in a thin-walled pendant cup of bark strips and plant fibers, decorated with lichen and attached to a forked twig.
