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 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.

Black-naped Orioles enjoy a wide menu of plants and animals. They are fond of fruit and berries, particularly figs. Besides large insects, they also take small animals, including nestlings. For this reason, during the breeding season of other birds, Black-naped Orioles are often chased away by other birds.

Black-naped Orioles rarely descend to the ground. They forage high in trees and usually say within the canopy. Nevertheless, they are not birds of the deep forest. Originally from coastal woodlands and mangroves, they have adapted to cultivated areas and parks and gardens.

Black-naped Orioles usually forage alone or in pairs. They are most active in the morning and evenings, making their melodious calls as they forage.

Breeding: Black-naped Orioles breed in Singapore. They build a cup-shaped nest at a fork at the end of a slender branch high in a tree. The nest is made from bark, small twigs, grass and roots. 2-3 bluish-white eggs with brown spots are laid. They hatch in about 2 weeks.
