The Sumba hornbill (Rhyticeros everetti) is a large bird in the Bucerotidae, or hornbill family. The scientific name commemorates British colonial administrator and zoological collector Alfred Hart Everett.
It is a medium-sized, blackish hornbill, approximately 70 cm long. The male is dark reddish-brown on the crown and nape, with a paler neck. The female has entirely black plumage. Both sexes have a large, dull, yellowish bill with a maroon patch at the base, a serrated casque, and an inflatable blue throat.
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). source
