Enter Bird's Name in Search Box:


Species: The Black-whiskered Vireo (Vireo altiloquus) is a tropical vireo seen along the southeastern perimeters of the US. It is in comparison to the Red-eyed Vireo in size, but with a larger bill, shows more of an amber coloured iris, instead of a red iris. Common on some of the Caribbean islands and is a spring and summer visitor to the mainland only. Prefers to make its habitat near the coast and mangroves.

Distinctions: The male and female are very similar looking in appearance. Has large bill with a visible hook at end of upper bill, same identifying features seen in other vireos. Gray head, white eye brows and face, with dark eye line and mustache. Greenish back and tail, dusky to yellow flanks and undertail, dull white throat and breast, no wings bars.

Voice: Nasal sounding, similar sounds to other vireo types, multiple call notes, more pressing than the Red-eyed Vireo. Prefers staying high in tree when singing and in its search for insects.

Nesting: Three to five white eggs, speckled with brown or black spots. Suspended from a fork in branches of trees. The nest is composed of strips of wood bark, plant fibres and lined with fine grasses and spiderwebs.
