Crested Quail-dove
The crested quail-dove (''Geotrygon versicolor'') is a species of bird in the family Columbidae. It is endemic to Jamaica. Taxonomy and systematics At one time the crested quail-dove was the sole member of genus ''Geotrygon''. Most of what are now the other species in the genus were previously in genus ''Oreopeleia'', which was merged into ''Geotrygon''. The crested quail-dove is monotypic.Baptista, L. F., P. W. Trail, H.

Frédéric De Lafresnaye
Baron Nöel Frédéric Armand André de Lafresnaye (24 July 1783 – 14 July 1861) was a French ornithologist and collector. Lafresnaye was born into an aristocratic family at Chateau de La Fresnaye in Falaise, Calvados, Falaise, Normandy. He took an early interest in natural history, particularly entomology. It was only after acquiring a collection of European birds that he turned his attention to ornithology. Lafresnaye described a number of new bird species, some with Alcide d'Orbigny. He accumulated a collection of over 8,000 bird skins at his home. After his death the collection was purchased by the American collector Henry Bryant (naturalist), Henry Bryant and donated to the Boston Society of Natural History, Boston Natural History Society. It was transferred to the Museum of Comparative Zoology in 1914. Lafresnaye's piculet, Lafresnaye's woodcreeper and Lafresnaye's vanga are avian species that bear his name.

John Crow Mountains
The John Crow Mountains are a range of mountains in Jamaica. They extend parallel with the northeast coast of the island, bounded to the west by the banks of the Rio Grande, and joining with the eastern end of the Blue Mountains in the southeast. The highest point in the range is a little over .UK Directorate of Overseas Surveys 1:50,000 map of Jamaica sheet N, 1967. The name John Crow was first recorded in the 1820s and comes from the Jamaican name for the turkey vulture. It has been suggested that previous to this, the range was known as the "Carrion Crow Ridge", after an earlier name for the vulture."Eager for Ecclesdown Road" a www.10000birds.com Accessed 29 July 2011.

Birds Described In 1846
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Birds Of Jamaica
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geotrygon
''Geotrygon'' is a bird genus in the pigeon and dove family (Columbidae). Its members are called quail-doves, and all live in the Neotropics. The species of this genus have ranges from southern Mexico and Central America to the West Indies and South America. Quail-doves are ground-dwelling birds that live, nest, and feed in dense forests. They are remarkable for their purple to brown coloration with light-and-dark facial markings. The genus ''Geotrygon'' was introduced in 1847 by English naturalist Philip Henry Gosse. The name combines the Ancient Greek ''geō-'' meaning "ground-" and ''trygōn'' meaning "turtledove". The type species was subsequently designated as the crested quail-dove (''Geotrygon versicolor''). The genus contains nine species: * Grey-fronted quail-dove, ''G. caniceps'' * Key West quail-dove, ''G. chrysia'' * †Puerto Rican quail-dove, ''Geotrygon larva'' - prehistoric * White-fronted quail-dove or Hispaniolan quail-dove, ''G. leucometopius'' * Ruddy quail-d ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cockpit Country
Cockpit Country is an area in Trelawny and Saint Elizabeth, Saint James, Saint Ann, Manchester and the northern tip of Clarendon parishes in Jamaica. The land is marked by steep-sided hollows, as much as deep in places, which are separated by conical hills and ridges. Maroons who had escaped from plantations used the difficult territory for its natural defences to develop communities outside the control of Spanish or British colonists. History In the late seventeenth century, the Cockpit Country was a place of refuge for Jamaican Maroons fleeing slavery. During the course of the First Maroon War, there were two Leeward Maroon communities - Cudjoe's Town (Trelawny Town) and Accompong Town. Cudjoe's Town was located in the mountains in the southern extremities of Saint James Parish, Jamaica, close to the border of Westmoreland Parish. Accompong is situated just to the south of Cudjoe's Town, on the border between Westmoreland and Saint Elizabeth Parish. When the Leeward Ma ...

Blue Mountains (Jamaica)
The Blue Mountains are the longest mountain range in Jamaica. They include the island's highest point, Blue Mountain Peak, at 2256 m (7402 ft). From the summit, accessible via a walking track, both the north and south coasts of the island can be seen. On a clear day, the outline of the island of Cuba, away, can also be seen. The mountain range spans four parishes: Portland, St. Thomas, St. Mary and St. Andrew. Geography The Blue Mountains dominate the eastern third of Jamaica, while bordering the eastern parishes of Portland, St. Thomas, St. Mary and St. Andrew to the south. Part of the Blue Mountains is contained in the Blue and John Crow Mountains National Park established in 1992, which is maintained by the Jamaican government. The Blue Mountains rise to its elevations from the coastal plain in the space of about , thus producing one of the steepest general gradients in the world. This forms cooling relief from the sweltering heat of the city of Kingston, visi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Covert
Secrecy is the practice of hiding information from certain individuals or groups who do not have the "need to know", perhaps while sharing it with other individuals. That which is kept hidden is known as the secret. Secrecy is often controversial, depending on the content or nature of the secret, the group or people keeping the secret, and the motivation for secrecy. Secrecy by government entities is often decried as excessive or in promotion of poor operation; excessive revelation of information on individuals can conflict with virtues of privacy and confidentiality. It is often contrasted with social transparency. Secrecy can exist in a number of different ways: encoding or encryption (where mathematical and technical strategies are used to hide messages), true secrecy (where restrictions are put upon those who take part of the message, such as through government security classification) and obfuscation, where secrets are hidden in plain sight behind complex idiosyncrati ...
