The Crowned hornbill (Tockus alboterminatus), is a species of hornbill in the Bucerotidae family. It is a medium-sized bird, 50–54 centimetres (20–21 in) in length, and is characterized by its white belly and black back and wings. The tips of the long tail feathers are white. The eyes are yellow; the beak is red and presents a stocky casque on the upper mandible. In females, the casque is smaller. The crowned hornbill can be distinguished from the similar Bradfield's hornbill by its shorter beak.
