Enter Bird's Name in Search Box:


Species: The Warbling Vireo (Vireo gilvus) along with the Red-eyed Vireo are the most common vireos seen in North America. Recognized by its warbling melody, heard from up high in mostly deciduous trees, it is heard more often than seen. Similar in appearances to the Philadelphia Warbler, who has all the same features but shows more yellow on its breast and flanks. Like other vireo species, its' main diet is insects.

Distinctions: The male and female are similar looking in appearance. Has large bill with a visible hook at end of upper bill, same identifying features seen in other vireos. Very plain in appearance, soft dull green or light brown body with a white breast, resembles warbler-type birds, but has a stockier build. Soft green to light brown plumage, has white eye browlines, no wing bars, slightly yellow coloured flanks.

Voice: Warbling melody, easily recognized, sings from high up in mature deciduous trees, heard more often than seen.

Nesting: Three to five white eggs, speckled with brown or black spots. Suspended from a crotch on a branch high up in a mature tree, very similar to the Red-eyed Vireo's eggs. The nest is composed of strips of wood bark, plant fibres and other fine materials.
