Green-backed Trogon (Trogon viridis)


French: Trogon à queue blanche German: Grünmanteltrogon Spanish: Trogón dorsiverde
Other common names: White-tailed Trogon (when lumped with T. chionurus)

Trogon viridis


, 1766,



Closely related to T. melanocephalus, T. citreolus and T. bairdii; sometimes considered conspecific with T. bairdii. Until recently treated as conspecific with T. chionurus. Birds from SE Brazil described as race melanopterus, but individual variation, as well as overlap in biometrics with populations elsewhere in species’ range, render separation doubtful. Species sometimes erroneously listed as T. strigilatus; this name was applied to female in same publication as first use of viridis, but present name was the one adopted by First Reviser. Monotypic.


E of Andes from Colombia S to Peru and N Bolivia, and E to the Guianas, Trinidad and E Brazil (to Maranhão and Mato Grosso; also Alagoas, and Bahia to São Paulo).
