Plumbeous Vireo

Vireo plumbeus

Closely related to the Cassin’s Vireo and the Blue-Headed Vireo, all were lumped together as the “Solitary Vireo” until 1997, when science decided that these birds each deserved their own status as ‘species’. These three birds can usually be separated by range, with Cassin’s in the west, Plumbeous in the intermountain and Great Basin region and Blue-Headed in the east. Their songs are so similar that they can be easily confused with one-another.
