Sumba Hornbills

The Sumba Hornbills (Rhyticeros everetti) is an Indonesian endemic.

Distribution / Habitat

It is distributed to semi-evergreen forests of Sumba in the Lesser Sunda Islands. It is uncommon and found in the lowland to altitudes up to 950 metres.


This is a medium-sized, approximately 70cm long, blackish hornbill. The male is dark reddish-brown on the crown and nape, and paler neck. The female has an entirely black plumage. Both sexes have a large dull yellowish bill with a maroon patch at the base, a serrated casque (a large display growth on the upper mandible of the bill), and an inflatable blue throat.

The Sumba Hornbills are a monogamous species.


The diet consists mainly of fruits.


Due to ongoing habitat loss, limited range, small population size and overhunting in some areas, the Sumba Hornbill is evaluated as Vulnerable on the IUCN Red List of Threatened Species. It is listed on Appendix II of CITES.
