About the Rhinoceros Hornbill
The rhinoceros hornbill (Buceros rhinoceros) is a large species of forest hornbill. In captivity, it can live for up to 35 years. It is found in lowland and montane, tropical and subtropical climates and in mountain rain forests up to 1,400 metres in the Malay Peninsula from southern Thailand; and the islands of Singapore, Borneo, Sumatra and Java.
The rhinoceros hornbill is the state bird of the Malaysian state of Sarawak and the country's national bird. It is scheduled as a "totally protected animal" under Sarawak law through the 1998 Wild Life Protection Ordinance.
The rhinoceros hornbill was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae. He placed it with the great hornbill in the genus Buceros and coined the binomial name Buceros rhinoceros, where he specified the location as India. The genus name comes from Ancient Greek βοῦς boûs meaning "ox", and κέρας kéras meaning "horn"; the species epithet rhinoceros comes from how the species' bill resembles a rhinoceros' horn.
