The Black-naped Oriole, Oriolus chinensis, is a member of the oriole family of passerine birds found in south Asia. This is easily differentiated from the Golden Oriole by the broad black eye-stripe continuing to join on the nape. The black eye-stripe can vary in width, with at least one possible racial variant having no yellow crown patch at all - the black eye-stripe being so wide that it forms a single black semi-hood on the head. The bill is also stouter than that of the former species.It breeds from June to December seasons. The female has the mantle colour more greenish or olive. The species is resident in the Andaman and Nicobar Islands. The races here are O. c. andamanensis and O. c. macrourus and differ in the pattern of yellow on the wings and tail as well as in the size of the bill. There is a possibility of cryptic species within this group.
They are migrants in most parts of South India and are most regularly seen in the Western Ghats.
Like other orioles they feed on insects and fruit. The nest is a deep cup in a fork of a tree.
