The courtship and bonding of these birds are critical, as the female must trust the male to provide her with everything when she is incubating and raising chicks.

The genus name is from Latin becerus meaning "horned like an ox" which in turn is from the Ancient Greek boukerōs which combines bous meaning "ox" with kerōs meaning "horn". Linnaeus specified the location as China. He placed it with the great hornbill in the genus Buceros and coined the binomial name Buceros rhinoceros. The rhinoceros hornbill was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae. It is featured on the reverse of the 5 Malaysian ringgit bill. Contrary to some misunderstandings, the rhinoceros hornbill does not represent their war god, who is represented in this world by the brahminy kite. Some Dayak people, especially the Ibanic groups, believe it to be the chief of worldly birds or the supreme worldly bird, and its statue is used to welcome the god of the augural birds, Sengalang Burong, to the feasts and celebrations of humankind. The rhinoceros hornbill is the state bird of the Malaysian state of Sarawak and the country's national bird. It is found in lowland and montane, tropical and subtropical climates and in mountain rain forests up to 1,400 metres in Borneo, Sumatra, Java, the Malay Peninsula, Singapore, and southern Thailand. In captivity it can live for up to 35 years. They still depend on parents for six months outside the nest.The rhinoceros hornbill ( Buceros rhinoceros) is a large species of forest hornbill ( Bucerotidae). They fledge about 78-80 days after hatching and take their first flight. The adults feed and care for the chicks until they are able to break out of the cavity on their own. Then, both parents and young seal again the nest entrance. When the chicks are large enough, the female breaks free. The male feeds her by regurgitating various food items. The female moults both tail and flight feathers after the laying. She lays 1-2 eggs and incubates during 40 days (37-46 days). The entrance hole is usually an elongated slit through which the male provides food to female and young. The female enters the tree cavity, and both mates seal the entrance with a paste including fruit, mud and faeces prior to the laying. The nesting ritual is typical of these birds. It nests in natural cavity, a hole in tall tree between 9 and 15 metres above the ground. The Rhinoceros Hornbill lays the eggs in January, March/June, September and November. The eyes are red surrounded by black eyering, and protected by long lashes. The bird rubs both bill and casque against the uropygial gland placed at the base of the tail, gradually involving the red-yellow-orange colour of the adult’s bill. The ivory bill and the casque are coloured orange, yellow and red with black base. It probably plays a role when the bird is calling by serving as a resonator for the sounds. The conspicuous casque is made of keratin and is hollow inside. The white tail is crossed by broad, black band. The Rhinoceros Hornbill has mainly black plumage overall, except the white vent and thighs. The species is currently considered Near Threatened. The Rhinoceros Hornbill is threatened by forest destruction and hunting for food but also for its feathers. They are monogamous with long-term pair bonds, usually for life. It lives in treetops and feeds on fruit, insects and small vertebrates. The Rhinoceros Hornbill is one of the largest hornbills, and it can live for up to 90 years in captivity. It frequents the primary evergreen forest, but it can be seen in more open habitats. It can be found in Borneo, Sumatra, Java, the Malay Peninsula, Singapore and S Thailand. The Rhinoceros Hornbill is the Malaysia’s National Bird. Bucerotiformes Order – Bucerotidae Family
