The colorful Blue-headed Vireo is a standout among more plain-plumaged relatives such as the Red-eyed Vireo. This handsome Neotropical migrant is easy to identify, with a blue-gray head set off by bold white "spectacles," bright yellow flanks, olive-green back, and white wingbars. Both sexes are very similar in appearance.
The Blue-headed Vireo's Latin species name solitarius echoes this bird's former common name — the Solitary Vireo — which was used until 1997.
