Rhyticeros undulatus
DESCRIPTION
The Wreathed Hornbill is a large bird characterized by its striking appearance, featuring a prominent, curved casque on its bill that is yellow and black. Its plumage is predominantly black with white underparts and a distinctive white stripe on the wings. These birds are known for their social behavior, often seen in pairs or small groups, and they play a crucial role in their ecosystem as seed dispersers.
FUN FACTS
- Wreathed Hornbills are known for their unique nesting behavior, where the female seals herself inside a tree cavity during breeding, leaving only a small opening for the male to feed her
- This behavior helps protect the female and chicks from predators
- | These birds have a fascinating social structure, often forming lifelong pair bonds, and they communicate with each other through a series of distinct calls that can be heard over long distances
