Hornbill FAQs

Quick answers to the things people most often ask about hornbills.

The casque is a structure on top of the bill, made largely of keratin. It is usually hollow and light, and it is thought to play a role in amplifying calls and showing a bird's age, sex, and condition.

Most hornbills nest in tree cavities, where the female seals herself inside using mud, droppings, and food. A narrow slit is left open, and the male passes food through it while she incubates the eggs and raises the chicks.

Hornbills live in tropical and subtropical Africa, Asia, and Melanesia. Habitats range from dense rainforest to open savannah, with the Papuan Hornbill found in New Guinea and nearby islands, and Von der Decken's Hornbill in East Africa.

Most eat a mix of fruit, insects, and small animals, though the balance varies by species. African savannah species such as the Northern Red-billed Hornbill often forage on the ground for insects, while many forest species rely heavily on fruit.

Not closely. Hornbills and toucans look similar because both evolved large bills for reaching and handling food, but this is an example of convergent evolution. Hornbills live in the Old World, and toucans in the Americas.
