Editing Hornbill (section)

==Cultural significance==
{{Further|Uchek Langmeitong}}

Most species' casques are very light, containing much airspace. However, the [[helmeted hornbill]] has a solid casque made of a material called [[hornbill ivory]], which is greatly valued as a carving material in China and Japan. It was used as a medium for the art of [[netsuke]]. Also used for hunting purposes in places like India. The [[Iban people]] of Borneo regards the Rhinoceros hornbill (known as Kenyalang) as the king of the worldly birds, who acts as the intermediary between the man and the God. 
The Wreathed hornbill (Undan) is believed by the Iban people to be the guide of dead souls to the lower world.
