Rhinoceros hornbill

Overview

The rhinoceros hornbill is a large forest bird of the Sunda region. Black plumage contrasts with pale thighs and a white tail crossed by a broad black band. Adult males have red eyes and an ivory bill beneath a prominent orange-red casque. Casque shape varies among the subspecies. The IUCN Hornbill Specialist Group describes canopy feeding, especially on figs, supplemented by other fruits and occasional animal prey. Pairs and small family groups predominate, with larger gatherings sometimes visiting fruiting trees.

The Saint Louis Zoo account, labelled Buceros rhinoceros silvestris, describes nesting inside large tree trunks. The female seals herself inside to incubate, receiving food from the male through a small opening. Both parents subsequently feed the chick until about eighty days old. The account presents a possible role for the casque in amplifying calls; that proposed function remains qualified.
