Fun Facts

  1. Red-billed hornbills nest in holes in trees where the female seals the entrance for two to three months while she incubates the eggs and feeds the young with insects brought to her by the male.
  2. Hornbills are unique because their first two neck vertebrae have been fused to support their large bill.
  3. They are territorial and will defend their space against their own species, but not other species, so several species of hornbill may have overlapping territories at one time.
  4. Red-billed hornbills have an interesting parental strategy. The female seals herself into a tree cavity, leaving only a small slit through which the male provides food. The female molts and re-grows her feathers during this time, then breaks out of the nest when the eldest chick is 21–22 days old. The chicks then reseal the entrance alone, using their droppings and food remains. Finally, the chicks fly from the nest, but remain with their parents for six months.
  5. When the chicks are about half grown, the female breaks out to assist the male in providing food. The chicks do not leave the nest cavity until they are able to fly.
  6. The red-billed hornbill has a close association with people, often benefiting from the insects and small reptiles that are drawn to people.
  7. Some of their ground-dwelling relatives in South Africa and Southeast Asia can grow to stand over 1m (3 ft) tall.

Ecology and Conservation

The red-billed hornbill's population is strong throughout its range. However, as with any species, their future status is highly dependent on habitat integrity as concerns human interaction. Because hornbills consume a large number of insects and small animals that are seen as pests, its future is important for a healthy ecosystem.
