The rhinoceros hornbill has a name as impressive as its unbelievable bill. Atop its bill is a feature called a casque, which has a striking upward curve like a rhino horn, hence the bird's common name. The strong bill is used for reaching fruit from thin tree branches, and that impressive casque is used as a resonating chamber to amplify the bird's loud calls.
