Great Hornbill

The great hornbill is one of the largest hornbills and a symbol of Asia’s tropical forests. It needs large old trees for nesting and is threatened by logging and hunting.

Interesting facts

  • Its wings make a loud whooshing sound in flight.
  • The yellow casque on top of the bill is hollow.
  • Birds rub preen-gland oil on the casque, making it more yellow.
  • Figs are among its most important foods.
  • Hornbills are major seed dispersers of large-fruited trees.
  • It is the state bird of Kerala and Arunachal Pradesh in India.

Behaviour

Great hornbills live in pairs or small groups and gather in large numbers at fruiting trees and roosts.

Breeding and young

The female lays one or two eggs in a sealed tree cavity and stays inside, moulting her flight feathers, until the chick is well grown.

Threats and conservation

Loss of large nesting trees, deforestation and hunting for meat, casques and feathers.
