Description

Rhinoplax vigil or well-known as helmeted hornbill is a very large hornbill that can grow up to 127 cm in length. It is a monotypic genus, which contains a single species. This species can be distinguished from other hornbills by its shorter conical bill, deeply truncated casque and elongated central tail feathers. It also has dark brown upperparts and breast contrasting with its white belly and tail. The sides and top of the casque and the base of its bill are red while the front end of the casque and the front half of the bill is yellow (Strange & Jeyarajasingam, 1993). There is a slight difference between male and female. The male has red bare and coarsely wrinkled skin around its neck while the female has sky-blue skin around its wrinkled neck.

Helmeted hornbill has an odd accelerating laughter that carries over a mile and can be heard just before take-off. It occurs from Myanmar to the Malay Peninsula, Sumatra and Borneo and can be found in foothills and elevations up to 1500 m above sea level. It also requires large expanses of primary forest with huge trees for their habitat. Logging activities, agricultural conversion, as well as hunting pressure for its casque has led this striking hornbill to be uplisted from Near Threatened to Critically Endangered in the IUCN Redlist of Threatened Species (BirdLife International, 2017). Conservation action like legislation enforcement, community involvement in protecting this species and monitoring the impact of hunting pressure on populations should be done.
