Hornbills
Hornbills (Bucerotidae) are a family of bird found in tropical and subtropical Africa, Asia and Melanesia. They are characterized by a long, down-curved bill which is frequently brightly coloured and sometimes has a casque on the upper mandible. Both the common English and the scientific name of the family refer to the shape of the bill, "buceros" being "cow horn" in Greek. Hornbills have a two-lobed kidney. They are the only birds in which the first and second neck vertebrae (the atlas and axis respectively) 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. In the Neotropical realm, toucans occupy the hornbills' ecological niche, an example of convergent evolution. De ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Southern Ground Hornbill
The southern ground hornbill (''Bucorvus leadbeateri''; formerly known as ''Bucorvus cafer'') is one of two species of ground hornbill, both of which are found solely within Africa, and is the largest species in the hornbill order worldwide. It can be found in the southern regions of Africa, ranging from Kenya to South Africa. Within these regions, they inhabit both woodlands and savannas. The other species of the genus ''Bucorvus'' is the Abyssinian ground hornbill, ''B. abyssinicus''. Southern ground hornbills are carnivorous and hunt mostly on the ground. Their food ranges from insects to small animals. Their nests are often found in high tree cavities or other shallow cavities, such as rock holes in cliff faces. These birds are a long-lived species, having lifespans in the range of 50–60 years, and up to 70 in captivity. In relation to their long lives, they do not reach sexual maturity until 4–6 years old, and begin breeding around 10 years old. Their sex can be identifi ...

Great Hornbill
The great hornbill (''Buceros bicornis''), 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, it is important in many tribal cultures and rituals. The Government of Kerala declared it as the official Kerala state bird. Taxonomy The great 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 rhinoceros hornbill in the genus ''Buceros'' and coined the binomial name ''Buceros bicornis''. Linnaeus specified the location as China. The genus name is from Latin ''becerus'' meaning "horned like an ox" w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casque (anatomy)
A casque is an anatomical feature found in some species of birds, reptiles, and amphibians. In birds, it is an enlargement of the bones of the or the skull, either on the front of the face, or the top of the head, or both. The casque has been hypothesized to serve as a visual cue to a bird's sex, state of maturity, or social status; as reinforcement to the beak's structure; or as a resonance chamber, enhancing calls. In addition, they may be used in combat with other members of the same species, in the gathering of food, or in thermoregulation. Birds Structure Casques are found in a number of species, including most hornbills, all cassowaries, the maleo, the horned guan, the helmeted guineafowl and several species of curassow. In most of these species, the casque is a bony extension of the or skull, covered with a cornified layer of skin. However, in cassowaries, a foamy, elastic layer of collagen sits between the bone and the skin. Hornbill casques grow from an area of vasc ...

Ground Hornbill
The ground hornbills (Bucorvidae) are a family of the order Bucerotiformes, with a single genus ''Bucorvus'' and two extant species. The family is endemic to sub-Saharan Africa: the Abyssinian ground hornbill occurs in a belt from Senegal east to Ethiopia, and the southern ground hornbill occurs in southern and East Africa. Ground hornbills are large, with adults around a metre tall. Both species are ground-dwelling, unlike other hornbills. Also unlike most other hornbills, they are carnivorous and feed on insects, snakes, other birds, amphibians and even tortoises.Kinnaird Margaret F. and O‘Brien< Timothy G.; ''The Ecology and Conservation of Asian Hornbills: Farmers of the Forest''; pp. 20-23. They are among the longest-lived of all birds, and the larger southern species is possibly the slowest-breeding (triennially) and longest-lived of all birds.

Aceros Cassidix -Vogelpark Walsrode -pair-8a
The rufous-necked hornbill (''Aceros nipalensis'') is a species of hornbill in Bhutan, northeastern India, especially in Arunachal Pradesh, Indian Subcontinent and Southeast Asia. It is locally extinct in Nepal due to hunting and significant loss of habitat. There are less than 10,000 adults left in the wild. With a length of about , it is among the largest Bucerotine hornbills. The underparts, neck and head are rich rufous in the male, but black in the female. Taxonomy The scientific name ''Buceros nipalensis'' was coined by Brian Houghton Hodgson in 1829 who described several rufous-necked hornbills caught by hunters in sal forest in Nepal. It was placed in the genus ''Aceros'' by John Edward Gray in 1844. Description The head, neck, and lower body of the male are coloured rufous, with deeper colouration on the flanks and abdomen. The middle primaries and the lower half of the tail are tipped white. The rest of the hornbill's plumage is a glossy dark-green and black. The ...

Wood Hoopoe
The wood hoopoes or scimitarbills are a small African family, Phoeniculidae, of near passerine birds. They live south of the Sahara Desert and are not migratory. While the family is now restricted to Sub-Saharan Africa, fossil evidence shows that it once had a larger distribution. Fossils attributed to this family have been found in Miocene rocks in Germany. The wood hoopoes are related to the kingfishers, the rollers, and the hoopoe, forming a clade with this last according to Hackett ''et al.'' (2008). A close relationship between the hoopoe and the wood hoopoes is also supported by the shared and unique nature of their stapes. The wood hoopoes most resemble the true hoopoes with their long down-curved bills and short rounded wings. According to genetic studies, the two genera, ''Phoeniculus'' and '' Rhinopomastus'', appear to have diverged about ten million years ago, so some systematists treat them as separate subfamilies or even separate families.

Hoopoe
Hoopoes () are colourful birds found across Africa, Asia, and Europe, notable for their distinctive "crown" of feathers. Three living and one extinct species are recognized, though for many years all of the extant species were lumped as a single species—''Upupa epops''. In fact, some taxonomists still consider all three species conspecific. Some authorities also keep the African and Eurasian hoopoe together but split the Madagascar hoopoe. The Eurasian hoopoe is common in its range and has a large population, so it is evaluated as Least Concern on The IUCN Red List of Threatened Species. However, their numbers are declining in Western Europe. Conversely, the hoopoe has been increasing in numbers at the tip of the South Sinai, Sharm el-Sheikh. There are dozens of nesting pairs that remain resident all year round. Taxonomy The genus ''Upupa'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. The type species is the ...

Neotropical Realm
The Neotropical realm is one of the eight biogeographic realms constituting Earth's land surface. Physically, it includes the tropical terrestrial ecoregions of the Americas and the entire South American temperate zone. Definition In biogeography, the Neotropic or Neotropical realm is one of the eight terrestrial realms. This realm includes South America, Central America, the Caribbean islands, and southern North America. In Mexico, the Yucatán Peninsula and southern lowlands, and most of the east and west coastlines, including the southern tip of the Baja California Peninsula are Neotropical. In the United States southern Florida and coastal Central Florida are considered Neotropical. The realm also includes temperate southern South America. In contrast, the Neotropical Floristic Kingdom excludes southernmost South America, which instead is placed in the Antarctic kingdom. The Neotropic is delimited by similarities in fauna or flora. Its fauna and flora are distinct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ramphastides
Ramphastides is an infraorder of the order Piciformes that includes toucans and barbets. Formerly, the barbets have been classified in a single family, the Capitonidae. However, this has turned out to be paraphyletic with regard to toucans, which resulted in the Capitonidae being split into several families. Systematics The Ramphastides contain five extant families. Sometimes, they are treated as the superfamily Ramphastoidea.Simpson, S. F., & Cracraft, J. (1981). The phylogenetic relationships of the Piciformes (Class Aves).

Honeyguide
Honeyguides (family Indicatoridae) are near passerine birds in the order Piciformes. They are also known as indicator birds, or honey birds, although the latter term is also used more narrowly to refer to species of the genus '' Prodotiscus''. They have an Old World tropical distribution, with the greatest number of species in Africa and two in Asia. These birds are best known for their interaction with humans. Honeyguides are noted and named for one or two species that will deliberately lead humans (but, contrary to popular claims, not honey badgers) directly to bee colonies, so that they can feast on the grubs and beeswax that are left behind. Description Most honeyguides are dull-colored, though some have bright yellow coloring in the plumage. All have light outer tail feathers, which are white in all the African species. The smallest species by body mass appears to be the green-backed honeyguide, at an average of , and by length appears to be the Cassin's honeyguide, at ...
