Aceros undulatus

The wreathed hornbill (Rhyticeros undulatus), also known as the bar-pouched wreathed hornbill, is a species of hornbill native to forests in northeast India, Bhutan, mainland Southeast Asia and the Greater Sundas in Indonesia.[1] It is 75–100 cm (30–39 in) long. Males weigh from 1.8 kg (4.0 lb) to 3.65 kg (8.0 lb), and females weigh from 1.36 kg (3.0 lb) to 2.7 kg (6.0 lb).[2] Both sexes are similar to the respective sexes of the closely related plain-pouched hornbill, but the wreathed hornbill can be recognized by the dark bar on the lower throat (hence the alternative common name, bar-pouched).[3] Though commonly considered monotypic, evidence suggests some geographical variation in the appearance.[3]
