Slender-billed Oriole (Oriolus tenuirostris)


Taxonomy

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

Oriolus tenuirostris

Blyth

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.
