Vireos (Vireonidae)

Plumbeous Vireo (Vireo plumbeus) - HBW 15, p. 424

French: Viréo plombé German: Weißstirnvireo Spanish: Vireo Plomizo
Other common names: Solitary Vireo (when treated as conspecific with V. cassinii and V. solitarius)

Taxonomy: Vireo plumbeus Coues, 1866, Fort Whipple, Arizona, USA.
Probably forms a superspecies with V. cassinii and V. solitarius; the three were formerly treated as conspecific, but molecular-genetic studies indicate that they merit treatment as separate species. Some authorities suggest that S races notius and montanus may both warrant elevation to rank of full species. Proposed race jacksoni (SC Montana) is synonymized with nominate; in Mexico, proposed races pinicolus (described from Mound Valley, in Chihuahua) and repetens (from Tixtla, in Guerrero) likewise treated as synonyms of nominate.

Four subspecies currently recognized.
