Due to this, the species was uplisted to vulnerable from near threatened on the IUCN Red List in 2018. It is frequently shot at by poachers due to confusion with the highly sought-after helmeted hornbill. Habitat destruction has led to the loss of the large trees the species requires for breeding, which in turn makes it easier for poachers to find the rhinoceros hornbill. The rhinoceros hornbill faces a number of threats, including loss of its rainforest habitat, as well as hunting for its meat, and its skull and feathers. Once the chicks are fully feathered and old enough to leave the nest, the parents chip away the dry mud to let the chicks out. They leave a very small hole, just large enough for the male to feed the female, and later the chicks, and for the female to defecate through the hole. After the eggs are laid, the male collects mud, and the pair pack that mud, along with food and feces, to wall up the entrance to the tree cavity. These hornbills make their nests inside tree trunks, and the female stays inside with the eggs and then with the chicks, while the male brings them food. 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. This feature comes from hadrosaurids from more than 60 million years ago.The rhinoceros hornbill ( Buceros rhinoceros) is a large species of forest hornbill ( Bucerotidae). Rhinoceros hornbills have one of the largest and most impressive casques.It is believed that it acts as a resonating chamber and helps birds to sound loudly across a large distance. Rhinoceros hornbills' casque is made of keratin and is hollow inside.At the age of 6 years, the casque and bill become orange and red this color comes from preen oil which birds rub on from the preen gland above the tail during grooming to help keep their feathers healthy. Rhinoceros hornbills have a huge casque and bill which are white in color when birds are born.The Rhinoceros hornbill 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 (the native people of Borneo), especially the Ibanic groups, believe the Rhinoceros hornbill 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.
