Slender-billed Oriole (Oriolus tenuirostris)


French: Loriot à bec effilé German: Dünnschnabelpirol Spanish: Oropéndola picofina

Oriolus tenuirostris


, 1846,

central India; error = Assam


Closely related to O. chinensis, and sometimes treated as conspecific; see also O. oriolus. Race invisus differs minimally, and perhaps doubtfully valid. Ranges listed are tentative, as status in many areas poorly known, partly because of taxonomic uncertainties and confusion with O. chinensis. Two subspecies currently recognized.

Subspecies and Distribution

  • O. t. invisus Riley, 1940 – S Vietnam (S Annam).
