Cool Facts
- The Plumbeous Vireo is the middle form in the "Solitary Vireo" complex. Formerly considered one species, three species now are recognized. In appearance it is the dullest of the three, and it has the hoarsest song, which is very similar to that of the Yellow-throated Vireo.
- Although the Plumbeous Vireo used to be considered in the same species as Cassin's Vireo, and they both occur in the same area on the eastern slope of the Sierra Nevada of California, no cases of hybridization of the two are known.
