Plain Pigeon
The plain pigeon (''Patagioenas inornata'') is a species of bird in the family Columbidae. It is found in the four Greater Antilles: Cuba, Hispaniola (in the Dominican Republic and Haiti), Jamaica, and Puerto Rico. Its natural habitats are forest, woodland, coastal desert, mangrove and swampy areas. It is threatened by habitat loss and illegal hunting. Description The plain pigeon is a large-bodied bird (38 cm 5 in that superficially resembles the common city pigeon. At a distance it appears pale blue-gray overall. The head, hindneck, breast, and part of the folded wing are colored with a red-wine wash. When folded, the wing shows a white leading edge; in flight, it forms a conspicuous wing bar. Legs and feet are dark red. The female is slightly smaller and duller than the male. Juveniles are browner overall, with pale wing margins and dark eyes. Taxonomy The plain pigeon is thought to represent a fairly recent island adaptation of the red-billed pigeon (''P. flavirostria' ...

Nicholas Aylward Vigors
Nicholas Aylward Vigors (1785 – 26 October 1840) was an Ireland, Irish zoologist and politician. He popularized the classification of birds on the basis of the quinarian system. Early life Vigors was born at Old Leighlin, County Carlow on 1785 as first son from Capt. Nicholas Aylward Vigors which served in 29th (Worcestershire) Regiment of Foot, 29th (Worcestershire) Regiment and, his first wife, Catherine Vigors, daughter of Solomon Richards of Solsborough. He matriculated at Trinity College, Oxford on November 1803 before he was admitted at Lincoln's Inn on November 1806. Without completing his studies, he served in the army during the Peninsular War from 1809 to 1811 and wounded in Battle of Barrosa, Battle of Barossa on 5 March 1811. Though, he haven't completed his studies yet, he still published "An inquiry into the nature and extent of poetick licence" in London at 1810. He then returned to Oxford to continued his studies and achieved his Bachelor of Arts on 1817 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juvenile (organism)
A juvenile is an individual organism that has not yet reached its adult form, sexual maturity or size. Juveniles can look very different from the adult form, particularly in colour, and may not fill the same niche as the adult form. In many organisms the juvenile has a different name from the adult (see List of animal names). Some organisms reach sexual maturity in a short metamorphosis, such as eclosion in many insects. For others, the transition from juvenile to fully mature is a more prolonged process—puberty in humans and other species, for example. In such cases, juveniles during this transformation are sometimes called subadults. Many invertebrates, on reaching the adult stage, are fully mature and their development and growth stops. Their juveniles are larvae or nymphs. In vertebrates and some invertebrates (e.g. spiders), larval forms (e.g. tadpoles) are usually considered a development stage of their own, and "juvenile" refers to a post-larval stage that is not full ...

Endemic Birds Of The Caribbean
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] |
Birds Of Haiti
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. Bird ...

Patagioenas
''Patagioenas'' is a genus of New World pigeons whose distinctness from the genus ''Columba'' was long disputed but ultimately confirmed. It is basal to the ''Columba''-''Streptopelia'' radiation. Their ancestors diverged from that lineage probably over 8 million years ago. While the biogeographic pattern of this group suggests that the ancestors of the typical pigeons and turtle-doves settled the Old World from the Americas, ''Patagioenas'' may just as well be the offspring of Old World pigeons which only radiated into different genera later, given that the cuckoo-doves (''Macropygia'') of Southeast Asia also seem to be closely related.Johnson ''et al.'' (2001), Cheke (2005) Taxonomy The genus ''Patagioenas'' was introduced by the German naturalist Ludwig Reichenbach in 1853 with the white-crowned pigeon (''Patagioenas leucocephala'') as the type species. The genus name combines the Ancient Greek ''patageō'' meaning "to clatter" and ''oinas'' meaning "pigeon". There are 17 s ...

Habitat Conservation
Habitat conservation is a management practice that seeks to conserve, protect and restore habitats and prevent species extinction, fragmentation or reduction in range. It is a priority of many groups that cannot be easily characterized in terms of any one ideology. History of the conservation movement For much of human history, ''nature'' was seen as a resource that could be controlled by the government and used for personal and economic gain. The idea was that plants only existed to feed animals and animals only existed to feed humans. The value of land was limited only to the resources it provided such as fertile soil, timber, and minerals. Throughout the 18th and 19th centuries, social views started to change and conservation principles were first practically applied to the forests of British India. The conservation ethic that began to evolve included three core principles: 1) human activities damage the environment, 2) there was a civic duty to maintain the environment ...

Extinction
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Maranon Pigeon
The Maranon pigeon or Peruvian pigeon (''Patagioenas oenops'') is a species of bird in the family Columbidae. It is found in Ecuador and Peru. Taxonomy and systematics The International Ornithological Committee (IOC) calls this species Maranon pigeon. The South American Classification Committee of the American Ornithological Society (AOS), the Clements taxonomy, and ''Handbook of the Birds of the World'' all call it Peruvian pigeon.Remsen, J.

Red-billed Pigeon
The red-billed pigeon (''Patagioenas flavirostris'') is a relatively large, robust species of pigeon. It's breeding range extends from southern Texas, United States, to Costa Rica. It's primarily found throughout coastal and lowland areas of Mexico and Central America. It belongs to a clade of ''Patagioenas'' which generally lack iridescent display plumage, except some vestiges in the pale-vented pigeon. Description Red-billed pigeons have largely dark, slate-gray plumage with a more maroon, though sometimes described as purple, head, neck, and wing coverts. They have pale red eyes with an orange orbital ring, along with a red bill with a yellow tip. Noticeably, they don't have iridescent collar plumage. A blue-gray belly and tail coverts, as well as a less brown back, distinguish it from most other species., such as the Ruddy Pigeon and Short-billed Pigeon. The only noticeable difference between males and females is that the females have a duller colored head and neck. Juveni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
