Black-naped Oriole

The black-naped oriole (Oriolus chinensis) is a passerine bird in the oriole family that is found in many parts of Asia. There are several distinctive populations within the wide distribution range of this species and in the past the slender-billed oriole (Oriolus tenuirostris) was included as a subspecies. Unlike the Indian 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. The black-naped oriole is medium-sized and overall golden with a strong pinkish bill and a broad black mask and nape. The adult male has the central tail feathers tipped yellow and the lateral ones are more broadly yellow. The female has the mantle colour more greenish or olive. The juvenile has a streaked underside. The nestling has dull greenish with brown streaks. The head and nape are more yellowish and the undertail coverts are yellow. Several variations exist in the populations that have been separated as subspecies.
