Distribution and habitatEdit

An Indonesian endemic, the Sumba hornbill inhabits semi-evergreen forests of Sumba in the Lesser Sunda Islands. It is uncommon and found in the lowlands at altitudes of up to 950 m (3,120 ft).


The Sumba hornbill is a monogamous species. Its diet consists mainly of fruits.

Status and conservationEdit

Due to ongoing habitat loss, limited range, small population size and overhunting in some areas, the Sumba hornbill is assessed as Vulnerable on the IUCN Red List of Threatened Species. It is listed on Appendix II of CITES. Part of its habitat is protected in the Laiwangi Wanggameti National Park and the Manupeu Tanah Daru National Park.[1]
