Male Rhinoceros Hornbill (Buceros bicornis)Male Rhinoceros Hornbill (Buceros bicornis). These hornbills are found only in the highest form of rainforest in the Malay Peninsula, Sumatra, Java and Borneo. They have rounded wings, which make it difficult and noisy for them to fly. They are rarely seen, because they inhabit the highest treetops, but their ungainly and noisy flight can easily be heard.This image is copyright and may not be used without specific authorization.
