The eastern dwarf hornbill (Horizocerus granti) is a species of hornbill in the family Bucerotidae. It is found in the African tropical rainforest of the Democratic Republic of the Congo. It was formerly considered to be a subspecies of the western dwarf hornbill (Horizocerus hartlaubi) with the English name "black dwarf hornbill".
The eastern dwarf hornbill was formally described in 1895 by the German orthithologist Ernst Hartert based on a specimen collected near the Aruwimi River, a tributary of the Congo River, during the Emin Pasha Relief Expedition led by Henry Morton Stanley. Hartert coined the binomial name Lophoceros granti. The specific epithet was chosen to honour the Scottish ornithologist William Ogilvie-Grant. [2] [3] This species is placed in the genus Horizocerus that was introduced in 1899 by the American ornithologist Harry C. Oberholser. [4]
Hornbills are birds found in tropical and subtropical Africa, Asia and Melanesia of the family Bucerotidae. They are characterized by a long, down-curved bill which is frequently brightly coloured and sometimes has a horny casque on the upper mandible. Hornbills have a two-lobed kidney. They are the only birds in which the first and second neck vertebrae are fused together; this probably provides a more stable platform for carrying the bill. The family is omnivorous, feeding on fruit and small animals. They are monogamous breeders nesting in natural cavities in trees and sometimes cliffs. A number of mainly insular species of hornbill with small ranges are threatened with extinction, namely in Southeast Asia.

First described by English zoologist Philip Sclater in 1878, it is endemic to the Bismarck Archipelago, where it mainly inhabits rainforest and cloud forest in mountain areas above 500 m (1,600 ft).
