A very large bird in the hornbill family. It is found in the Malay peninsula, Sumatra and Borneo. This species has a bare, wrinkled throat patch, blue in females and red in males. Unlike other hornbills, the Helmeted Hornbill’s casque is solid, and the skull including the casque and bill may constitute 10 percent of the bird’s weight. The call is described as hoots followed by maniacal laughter.
