All hornbills have a casque, or hard structure, on top of their bill. The size and color of this casque can vary depending on size and gender, but the rhinoceros hornbill’s casque is especially impressive and distinguishes it from other hornbills. It is believed the casque amplifies sound and vocalizations made by the hornbill.
