Ocyceros is a genus of birds in the family Bucerotidae. Established by Allan Octavian Hume in 1873, it contains the following species,[1] which are limited to the Indian subcontinent.[2]

Description[edit]

Hornbills in the genus Ocyceros are small Asian birds that have curved triangular bills and grey plumage, therefore being called Grey hornbills. They have black and grey eye rings and their eyes are usually dark with black irises like most birds. All of the species have different coloured bills with the Indian grey hornbill having a dark greyish bill, the Sri Lanka grey hornbill having a pale yellowish bill and the Malabar grey hornbill having a more yellowish orange bill.
