About Treron curvirostra (J.F.Gmelin, 1789)
Treron curvirostra, commonly known as the thick-billed green pigeon, is a rather small species of green pigeon, with individuals growing to less than 26 cm (10 in) in length. Several features identify this species: a thick pale greenish bill with a red base, a broad bluish-green eye ring, a grey crown, and a maroon mantle. On the wings, the primary and secondary feathers are black, with yellow outer edges. The underside of the body is green in both sexes. Thighs are dark green and marked with whitish scaling. Females have greenish undertail coverts with whitish scaling, while males have a maroon dorsum and dull chestnut undertail coverts.
This species ranges across the eastern regions of the Indian subcontinent and Southeast Asia, stretching from the Eastern Himalayas to Borneo and Sumatra. It can be found across Bangladesh, Bhutan, Brunei, Cambodia, Hong Kong, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, the Philippines, Singapore, Thailand, Tibet and Vietnam. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical mangrove forests.
Treron curvirostra is known to feed on the syconia of figs, walking slowly along tree branches when foraging.
