The Black-naped oriole (Oriolus chinensis), is a species of Old World oriole in the Oriolidae family and is found in many parts of Asia. There are several distinctive populations within wide distribution range of the species and in the past the slender-billed oriole (Oriolus tenuirostris) was included as a subspecies. Unlike the Eurasian golden oriole which only has a short and narrow eye-stripe, the black-naped oriole has the stripe broadening and joining at the back of the neck. Males and females are very similar although the wing lining of the female is more greenish. The bill is pink and is stouter than in the golden oriole.
