Hornbills are birds found in tropical and subtropical Africa, Asia and Melanesia of the family Bucerotidae. They are characterized by a long, down-curved bill which is frequently brightly coloured and sometimes has a horny casque on the upper mandible. Hornbills have a two-lobed kidney. They are the only birds in which the first and second neck vertebrae 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, mainly in Southeast Asia.
The yellow-casqued hornbill, also known as the yellow-casqued wattled hornbill, is found in the rainforest of coastal regions of West Africa, for example in Côte d'Ivoire. It is threatened by habitat loss.
The Congo pied hornbill is a bird of the hornbill family, a family of tropical near-passerine birds found in the Old World.
The Malabar gray hornbill is a hornbill endemic to the Western Ghats and associated hills of southern India. They have a large beak but lack the casque that is prominent in some other hornbill species. They are found mainly in dense forest and around rubber, arecanut or coffee plantations. They move around in pairs or small groups, feeding on figs and other forest fruits. Their loud cackling and laughing call makes them familiar to people living in the region.
The Malabar pied hornbill, also known as the lesser pied hornbill, is a bird in the hornbill family, a family of tropical near-passerine birds found in the Old World.
Walden's hornbill locally called dulungan, also known as the Visayan wrinkled hornbill, rufous-headed hornbill or writhe-billed hornbill, is a critically endangered species of hornbill living in the rainforests on the islands of Negros and Panay in the Philippines. It is closely related to the writhed hornbill, but can be recognized by the yellow throat and ocular skin in the male, and the blue throat and ocular skin in the female. Its binomial name commemorates the Scottish ornithologist Viscount Walden.

The great hornbill, also known as the concave-casqued hornbill, great Indian hornbill or great pied hornbill, is one of the larger members of the hornbill family. It occurs in the Indian subcontinent and Southeast Asia. It is predominantly frugivorous, but also preys on small mammals, reptiles and birds. It has been listed as Vulnerable on the IUCN Red List since 2018. It is known to have lived for nearly 50 years in captivity. Due to its large size and colour, and importance in many tribal cultures and rituals, the Government of Kerala declared it as the official Kerala state bird.
The wreathed hornbill 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.
Bucerotiformes is an order of birds that contains the hornbills, ground hornbills, hoopoes and wood hoopoes. These birds were previously classified as members of Coraciiformes. The clade is distributed in Africa, Asia, Europe and Melanesia.
The black-and-white-casqued hornbill also known as the grey-cheeked hornbill, is a large black and white hornbill. It has an oversized blackish bill with a large casque on top. The female is slightly smaller than the male and has a significantly smaller casque. It is a monogamous species, and pairs nest in suitable tree cavities. The female usually lays up to two eggs. The diet consists mainly of figs, fruits, insects and small animals found in the trees.
The rufous hornbill, also known as the Philippine hornbill and locally as kalaw, is a large species of hornbill endemic to the Philippines. They are referred by locals as the "clock-of-the-mountains" due to its large booming call which typically occur of every hour. It occurs in moist tropical lowland forest. They are now considered to be a threatened species and its reasons for decline being habitat destruction, hunting and poaching for the illegal pet trade.
The Palawan hornbill is a large forest bird endemic to the Philippines. It is one of the 11 endemic hornbills in the country. It is only found in Palawan and nearby islands of Balabac, Busuanga, Calauit, Culion and Coron. It is locally known as "talusi" in the language Cuyunon. It is threatened by habitat loss, hunting and trapping for the cage-bird trade.
The black hornbill is a species of bird of the hornbill family Bucerotidae. It lives in Asia in Brunei Darussalam, Indonesia, Malaysia, Singapore, Thailand.
The writhed hornbill, also known as the Mindanao wrinkled hornbill, is a species of hornbill in the family Bucerotidae. It is endemic to primarily lowland forests on the Philippine islands of Mindanao, Dinagat and Camiguin Sur. It formerly included the Walden's hornbill as a subspecies, but unlike that species, both sexes of the writhed hornbill have orange-red throat and peri-ocular skin. The writhed hornbill is threatened by habitat loss and hunting.
The Narcondam hornbill is a species of hornbill in the family Bucerotidae. It is endemic to the Indian island of Narcondam in the Andamans. Males and females have a distinct plumage. The Narcondam hornbill has the smallest home range out of all the species of Asian hornbills.

It is endemic to the Sulu archipelago in the Philippines, with the remaining populations in Tawi-Tawi with it believed to be hunted to extinction on Jolo. Its natural habitat is tropical moist forests. It is threatened by habitat loss as well as potential harvesting for food. Its diet includes fruit, insects, and small lizards.
The brown-cheeked hornbill is a species of hornbill in the family Bucerotidae. It is found in Ivory Coast, Ghana, Guinea, Liberia, Sierra Leone, and Togo. Its natural habitats are tropical and subtropical moist broadleaf forests, plantations, and secondary growth forests. It is threatened by habitat destruction, as timber is harvested and the forests become increasingly fragmented.
The Mindoro hornbill is a species of hornbill in the family Bucerotidae. It is endemic to forests on Mindoro in the Philippines found in tropical moist lowland forests. As is the case with all five Philippine tarictic hornbills, formerly considered to be just one species. It is the only tarictic hornbill where both sexes are creamy-white and black. The sexes are very similar, differing primarily in the colour of the ocular ring. It is threatened by habitat loss, and is consequently considered endangered by the IUCN.
