Orioles (Oriolidae)

Slender-billed Oriole (Oriolus tenuirostris) - HBW 13, p. 723

French: Loriot à bec effilé German: Dünnschnabelpirol Spanish: Oropéndola Picofina
Other common names: Slender-billed Black-naped Oriole

Taxonomy: Oriolus tenuirostris Blyth, 1846, central India; error = Assam.
Closely related to and sometimes treated as conspecific with O. chinensis, the two forming a superspecies; alternatively, both sometimes considered to belong to the superspecies formed by O. oriolus, O. kundoo and O. auratus. Race invisus regarded by some authors as being of doubtful validity. 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.
