Description:

The Plumbeous Vireo was once lumped together with two other species, the Cassin's Vireo and the Blue-heade Vireo, to form a single species, the "Solitary Vireo". The Plumbeous Vireo forages by gleaning insects from twigs and foliage in a slow and deliberate manner. Will also sometimes eat fruit in the winter.
