It is the state bird of Sarawak in Malaysia and a cultural symbol for the Dayak peoples of Borneo.

Fun facts

  • reproducciónThe female seals herself into the nest cavity with mud and droppings, leaving only a narrow slit through which the male passes her food while she incubates.
  • It paints its own casque: the orange and red is not its own pigment but the secretion of the preen gland, which the bird rubs against the casque until it is stained, and a poorly preserved museum specimen loses that colour.
  • As in all Asian hornbills, the female walls herself into the nest hole for months, sealing the entrance and depending entirely on the male.
  • For the Dayak of Borneo it is the bird that guides the souls of the dead, and its feathers and casque play a central part in several traditional ceremonies.
