The Warbling Vireo is a small songbird found across North America, particularly in wooded areas and along riverbanks. It measures about 5 to 6 inches in length and has a distinctive olive-green back, pale underparts, and a faintly streaked breast. This bird is known for its melodious song, which consists of a series of warbling notes. During the breeding season, the Warbling Vireo builds a cup-shaped nest in trees, often using plant fibers and spider silk. It primarily feeds on insects and berries, playing a role in controlling insect populations. The species is migratory, wintering in parts of Central America and Mexico.
