Rhyticeros
''Rhyticeros'' is a genus of medium to large hornbills (family Bucerotidae) found in forests from Southeast Asia to the Solomons. They are sometimes included in the genus ''Aceros''. On the other hand, most species generally placed in ''Aceros'' are sometimes moved to ''Rhyticeros'', leaving ''Aceros'' as a monotypic genus only containing the rufous-necked hornbill. All species generally placed in ''Rhyticeros'' have relatively low, conspicuously wreathed casques and a mainly dull whitish horn-colored bill. Both sexes have mainly black plumage, but the head and neck of the males are white or rufous. The tail is white except in the black-tailed Sumba hornbill. They have conspicuous inflatable skin on the throat, which is blue in all except the males of the plain-pouched and wreathed hornbills, where it is yellow. Species As generally recognized, the following species belong in the genus ''Rhyticeros'': An undescribed extinct hornbill species from Lifou in the Loyalty Islands, ...

Wreathed Hornbill
The wreathed hornbill (''Rhyticeros undulatus'') is an Old World tropical bird of the hornbill family Bucerotidae, also called bar-pouched wreathed hornbill due to its distinctive blue-black band on its lower throat sac. It is named after its characteristic long, curved bill that develops ridges, or wreaths, on the casque of the upper mandible in adults. Males are black with a rufous crown, a white upper breast and face, and a yellow featherless throat. Females are uniformly black with a blue throat and are slightly smaller than males. The wreathed hornbill ranges across the foothills and evergreen forests of Northeast India and Bhutan to Bangladesh, Southeast Asia and the Greater Sunda Islands. It is a frugivore and feeds mainly on large fruits, which it swallows whole leaving the seeds intact. This feeding behaviour plays an important ecological role for the long-distance seed dispersal in forest ecosystems. The wreathed hornbill is threatened by hunting, habitat fragmentation ...

Bucerotidae
Hornbills (Bucerotidae) are a family of bird found in tropical and subtropical Africa, Asia and Melanesia. They are characterized by a long, down-curved bill which is frequently brightly coloured and sometimes has a casque on the upper mandible. Both the common English and the scientific name of the family refer to the shape of the bill, "buceros" being "cow horn" in Greek. Hornbills have a two-lobed kidney. They are the only birds in which the first and second neck vertebrae (the atlas and axis respectively) 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. In the Neotropical realm, toucans occupy the hornbills' ecological niche, an example of convergent evolution. Des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
