Vireos (Vireonidae)

Grey-eyed Greenlet (Hylophilus amaurocephalus) - HBW 15, p. 435

French: Viréon aux yeux gris German: Grauaugenvireo Spanish: Verdillo Ojigrí

Taxonomy: Sylvia amaurocephala Nordmann, 1835, boundary of Bahia and Minas Gerais, Brazil.
Formerly treated as conspecific with H. poicilotis, with which partly sympatric, but appears to be clearly differentiated by plumage, eye colour, vocalizations and habitat preference. Previously reported hybridization between the two explained as being due to presence of a "residual cline" that reflects geographical variation of the ancestor. Monotypic.

Distribution: NE Brazil, from Piauí and Ceará S through Bahia and Minas Gerais to N São Paulo; also, apparently disjunctly, in SW Mato Grosso do Sul and Bolivia (Beni).
