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, namely in Southeast Asia.
The Congo pied hornbill or African pied hornbill is a bird of the hornbill family, a family of tropical near-passerine birds found in the Old World.
The crowned hornbill is an African hornbill.
The wrinkled hornbill or Sunda wrinkled hornbill is a medium-large hornbill which is found in forest in the Thai-Malay Peninsula, Sumatra and Borneo. The hornbill is also found in some parts of Africa like Malawi but with white head.
The yellow-rumped cacique is a passerine bird in the New World family Icteridae. It breeds in much of northern South America from Panama and Trinidad south to Peru, Bolivia and central Brazil. However, they have been sighted as far north as Nayarit state in Mexico.
The helmeted hornbill is a very large bird in the hornbill family. It is found on the Malay Peninsula, Sumatra, Borneo, Thailand and Myanmar. The casque accounts for some 11% of its 3 kg weight. Unlike any other hornbill, the casque is almost solid, and is used in head-to-head combat among males. It is a belief among the Punan Bah that a large helmeted hornbill guards the river between life and death.
The silvery-cheeked hornbill is a large species of hornbill found in Africa. Silvery-cheeked hornbills are residents of the tall evergreen forests of East Africa from Ethiopia to South Africa. In Zimbabwe it is threatened by habitat destruction and its presence in South Africa is marginal, but it remains locally fairly common, especially in the northern and central parts of its range.
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 caciques are passerine birds in the New World blackbird family which are resident breeders in tropical South America north to Mexico. All of the group are in currently placed in the genus Cacicus, except the aberrant yellow-billed cacique, and the Mexican cacique which constitute respective monotypic genera. Judging from mitochondrial DNA cytochrome b and NADH dehydrogenase subunit 2 sequence, the aberrant oropendolas band-tailed oropendola and casqued oropendola, Psarocolius oseryi seem to be closer to the caciques.
The subtropical cacique is a passerine bird species in the New World family Icteridae. It breeds in the lower reaches of the northern Andes.
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 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 black-casqued hornbill, or black-casqued wattled hornbill, is a species of hornbill in the family Bucerotidae. It is found fairly commonly across sub-Saharan Africa, being known from Sierra Leone and Liberia in Western Africa, south to Angola and east to the Democratic Republic of the Congo and western Uganda. The population is decreasing.
The mountain cacique is a species of bird in the family Icteridae. It is found in Bolivia, Colombia, Ecuador, Peru, and Venezuela.
The golden-winged cacique is a species of bird in the family Icteridae. It is found in Argentina, Bolivia, Brazil, Paraguay, and Uruguay.
The red-rumped cacique is a species of bird in the family Icteridae. It is a species of the Amazon Basin and the Guyanas in northern South America, and is only coastal there in the Guyanas and the Amazon River outlet to the Atlantic; a separate large disjunct range exists in all of south-eastern and coastal Brazil, including Paraguay, and parts of north-eastern Argentina. It is also found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela.
The Selva cacique is a species of bird in the family Icteridae. It is endemic to Peru where its natural habitat is subtropical or tropical moist lowland forests. It is an uncommon and elusive bird and is threatened by habitat destruction; the population is thought to be declining rapidly and the International Union for Conservation of Nature has assessed the bird's conservation status as being "Near Threatened".
The Ecuadorian cacique is a species of bird in the family Icteridae. It is found in Colombia, Ecuador, and Peru, where its natural habitat is subtropical or tropical moist lowland forest. A fairly common bird with a wide range, the IUCN has rated it a "species of least concern".
The solitary cacique or solitary black cacique is a species of bird in the family Icteridae.
The band-tailed cacique, formerly the band-tailed oropendola, is a species of bird in the family Icteridae.
