The orange-bellied leafbird (Chloropsis hardwickii/橙腹叶鹎) is a bird native to the eastern Himalayas and south China to the Malay Peninsula. It is brightly colored with an orange belly, a green back, a blue tail and flight feathers, and a black and blue patch over its throat and chest. It has a long, curved beak. It feeds on insects, spiders and nectar. Orange-bellied leafbirds make their nests from roots and fibers which are suspended from the edges of twigs at the end of a tree branch. They do not migrate.
The scientific name commemorates the English naturalist Thomas Hardwicke.
