Black-hooded Coucal
The black-hooded coucal (''Centropus steerii'') is a species of cuckoo in the family Cuculidae. It is endemic to Mindoro in the Philippines and is one of the most endangered birds in the country. It is threatened by habitat loss and trapping. Description EBird describes the bird as "A large, long-tailed bird of lowland primary forest on Mindoro with a brown back and belly, dark wings with brown-edged feathers, a dark tail with a bluish iridescence, and a black hood with some light streaking on the back of the neck. Note the strong curved bill. Similar to Philippine coucal, but has a brown rather than black belly and is restricted to primary forest rather than more open habitats. Song is a descending series of very deep hoots." Habitat and conservation status Its natural habitat is tropical moist lowland forest. It is threatened by habitat loss with Mindoro having a great loss of forest in recent decades. By 1988, extensive deforestation on Mindoro had reduced forest cover t ...

Frank Swift Bourns
Frank Swift Bourns (1866 – 1935) was an American ornithologist and doctor. He was involved in two different expeditions to the Philippines with Dean Conant Worcester to gather natural history specimens. From 1887 to 1888 they participated in an expedition sponsored by Joseph Beal Steere. From 1890 to 1892 they returned on an expedition sponsored by Louis F. Menage and the Minnesota Academy of Natural Sciences. The two expeditions yielded thousands of specimens of birds and mammals including newly discovered species such as the Bornean slow loris and Sulu bleeding-heart The Sulu bleeding-heart (''Gallicolumba menagei'') is a species of bird in the pigeon and dove family, Columbidae. It is endemic to the island of Tawi-Tawi and its surrounding islets in the Philippines' Sulu Archipelago. This species is known on .... After the second expedition Bourns moved to Ann Arbor, Michigan where he completed his medical degree and became a doctor. References American ornith ...

Taxa Named By Frank Swift Bourns
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1894
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the 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 loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Birds ...

Centropus
A coucal is one of about 30 species of birds in the cuckoo family. All of them belong in the subfamily Centropodinae and the genus ''Centropus''. Unlike many Old World cuckoos, coucals are not brood parasites, though they do have their own reproductive peculiarity: all members of the genus are (to varying degrees) sex-role reversed, so that the smaller male provides most of the parental care. At least one coucal species, the black coucal, is polyandrous. Some species (''Centropus phasianinus'') have the male investing more in incubation and parental care. Taxonomy The genus ''Centropus'' was introduced in 1811 by the German zoologist Johann Karl Wilhelm Illiger. The type species was subsequently designated as the Senegal coucal by George Robert Gray in 1840. The genus name combines the Ancient Greek ''kentron'' meaning "spur" or "spike" with ''pous'' meaning "foot". Description Many coucals have a long claw on their hind toe (hallux). The feet have minute spurs and this is respo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EDGE Species
Evolutionarily Distinct and Globally Endangered (EDGE) species are animal species which have a high 'EDGE score', a metric combining endangered conservation status with the genetic distinctiveness of the particular taxon. Distinctive species have few closely related species, and EDGE species are often the only surviving member of their genus or even higher taxonomic rank. The extinction of such species would therefore represent a disproportionate loss of unique evolutionary history and biodiversity. Some EDGE species, such as elephants and pandas, are well-known and already receive considerable conservation attention, but many others, such as the vaquita (the world's rarest cetacean) the bumblebee bat (arguably the world's smallest mammal) and the egg-laying long-beaked echidnas, are highly threatened yet remain poorly understood, and are frequently overlooked by existing conservation frameworks. The Zoological Society of London launched the EDGE of Existence Programme in 2007 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zoological Society Of London
The Zoological Society of London (ZSL) is a charity devoted to the worldwide conservation of animals and their habitats. It was founded in 1826. Since 1828, it has maintained the London Zoo, and since 1931 Whipsnade Park. History On 29 November 1822, the birthday of John Ray, "the father of modern zoology", a meeting held in the Linnean Society in Soho Square led by Rev. William Kirby, resolved to form a "Zoological Club of the Linnean Society of London". Between 1816 and 1826, discussions between Stamford Raffles, Humphry Davy, Joseph Banks and others led to the idea that London should have an establishment similar to the Jardin des Plantes in Paris. It would house a zoological collection "which should interest and amuse the public." The society was founded in April 1826 by Sir Stamford Raffles, the Marquess of Lansdowne, Lord Auckland, Sir Humphry Davy, Robert Peel, Joseph Sabine, Nicholas Aylward Vigors along with various other nobility, clergy, and natural ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider p ... [...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, intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dean Conant Worcester
Dean Conant Worcester, D.Sc., FRGS (October 1, 1866 – May 2, 1924) was an American zoologist, public official, and authority on the Philippines. He was born at Thetford, Vermont, and educated at the University of Michigan (A.B., 1889). He first went to the Philippines in 1887 as a junior member of a scientific expedition, and built a controversial career in the early American colonial government beginning in 1899 based upon his experience in the country. He was fiercely opposed to Philippine independence and a firm believer in the colonial mission. He served as the influential Secretary of the Interior of the Philippine Islands until 1913 when he began focusing on his business interests. He died in the Philippines having organized and managed businesses that included coconut farming and processing, cattle raising and a maritime shipping line.Sullivan, Rodney J. (1991).
