Writhed Hornbill
The writhed hornbill (''Rhabdotorrhinus leucocephalus''), also known as the Mindanao wrinkled hornbill, is a species of hornbill in the family Bucerotidae. It is endemic to humid 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 Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby ... and hunting.

Louis Jean Pierre Vieillot
Louis Pierre Vieillot (10 May 1748, Yvetot – 24 August 1830, Sotteville-lès-Rouen) was a French ornithologist. Vieillot is the author of the first scientific descriptions and Linnaean names of a number of birds, including species he collected himself in the West Indies and North America and South American species discovered but not formally named by Félix de Azara and his translator Sonnini de Manoncourt. He was among the first ornithologists to study changes in plumage and one of the first to study live birds. At least 77 of the genera erected by Vieillot are still in use. Biography Vieillot was born in Yvetot. He represented his family's business interests in Saint-Domingue (Haiti) on Hispaniola, but fled to the United States during the Haitian rebellions that followed the French Revolution. On Buffon's advice, he collected material for the ''Histoire naturelle des oiseaux de l'Amérique Septentrionale,'' the first two volumes of which were published in France beginning i ...

Aceros Leucocephalus -Cagayan De Oro City, Mindanao, Philippines -male-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 ...

Birds Described In 1816
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the Common ostrich, ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of Camiguin
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is '' funga''. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemic Birds Of The Philippines
This article is one of a series providing information about endemism among birds in the world's various zoogeographic zones. For an overview of this subject see Endemism in Birds. Patterns of endemism Under the most up-to-date taxonomy, there are 237 bird species endemic to the Philippines. Many of these are restricted to specific islands, particularly Luzon, Mindanao, and Palawan."A Guide to the Birds of the Philippines", Robert S. Kennedy et al., Oxford University Press, 2013. The number of endemic species recognized in the Philippines has increased in recent years, mainly due to 'splits' of species and, to a much lesser extent, due to the discovery of previously unknown species. An example of splitting is the division of the erstwhile species Philippine hawk-owl (''Ninox scutulata'') into seven different species, now called by the name of this-or-that Boobook (Luzon Boobook, Mindoro Boobook, etc...see the list below). Another example is the split of the erstwhile tarictric h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hornbill
Hornbills (Bucerotidae) are a family (biology), 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 (anatomy), casque on the upper mandible. Both the common English (language), English and the scientific name of the family refer to the shape of the bill, "buceros" being "cow horn" in Greek language, Greek. Hornbills have a two-lobed kidney. They are the only birds in which the first and second vertebra, neck vertebrae (the atlas (anatomy), atlas and axis (anatomy), 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 Island, insular species of hornbill with small ranges are Threatened species, threatened with extinction, ...

Walden's Hornbill
Walden's hornbill (''Rhabdotorrhinus waldeni'') locally called dulungan, also known as the Visayan wrinkled hornbill, rufous-headed hornbill or writhed-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 (both throat and ocular skin are deep orange or red in both sexes of the writhed hornbill). Its binomial name commemorates the Scottish ornithologist Viscount Walden. It is considered one of the Western Visayas Big 5 which includes the Negros bleeding-heart pigeon, Visayan spotted deer, Visayan hornbill and the Visayan warty pig. Description EBird describes the bird as "A large rare bird of lowland and foothill forest on Panay and Negros, although almost extinct on the latter. Mostly black with a cream-colored tail ...
