Yellow-shouldered Amazon
The yellow-shouldered amazon (''Amazona barbadensis''), also known as the yellow-shouldered parrot, is a parrot of the genus ''amazon parrot, Amazona'' that is found in the arid areas of northern Venezuela, the Venezuelan islands of Isla Margarita, Margarita and Blanquilla Island, La Blanquilla, and the island of Bonaire (Caribbean Netherlands). It has been Local extinction, extirpated from Aruba and introduced to Curaçao. Taxonomy The yellow-shouldered amazon was described and illustrated in 1738 by the English naturalist Eleazar Albin in his ''A Natural History of Birds'' based on live specimen. Albin believed that the parrot had come from Barbados and used the English name, the "Barbadoes parrot". Using Albin's account, both Mathurin Jacques Brisson in 1760 and John Latham (ornithologist), John Latham in 1781 included a description of the parrot in their books on birds. When in 1788 the German naturalist Johann Friedrich Gmelin revised and expanded Carl Linnaeus's ''Systema ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Binomial Name
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deserts And Xeric Shrublands
Deserts and xeric shrublands are a biome defined by the World Wide Fund for Nature. Deserts and xeric (ancient Greek xērós, “dry") shrublands form the largest terrestrial biome, covering 19% of Earth's land surface area. Ecoregions in this habitat type vary greatly in the amount of annual rainfall they receive, usually less than annually except in the margins. Generally evaporation exceeds rainfall in these ecoregions. Temperature variability is also diverse in these lands. Many deserts, such as the Sahara, are hot year-round, but others, such as East Asia's Gobi, become quite cold in winter. Temperature extremes are a characteristic of most deserts. High daytime temperatures give way to cold nights because there is no insulation provided by humidity and cloud cover. The diversity of climatic conditions, though quite harsh, supports a rich array of habitats. Many of these habitats are ephemeral in nature, reflecting the paucity and seasonality of available water.

Macanao Peninsula Municipality
The Macanao Peninsula is a geographic peninsula landform, that forms the western end of the Isla Margarita in the Caribbean Sea, in northern Venezuela. It is also a Venezuelan municipality, the Municipality of Macanao Peninsula (''Municipio Península de Macanao''), in the state of Nueva Esparta. The municipal seat is Boca de Río. Geography The peninsula is connected to the rest of Isla Margarita by a thin strip of land in Laguna de la Restinga National Park. Sixty years ago, it was an island. The peninsula has an area of , rising from sea level to at the peak of Cerro Macanao. A ridge of high land runs along the peninsula from east to west. The main east-west crest is sharp and narrow. The mountains are smaller than in Maragarita, but are much more rugged, with many steep-sided valleys cutting through the mountain sides. The more remote beaches can only be reached via dirt roads. The climate of Margarita as a whole is hot and tropical, with little rainfall. The Macan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orange-winged Amazon
The orange-winged amazon (''Amazona amazonica''), also known locally as orange-winged parrot and loro guaro, is a large amazon parrot. It is a resident breeding bird in tropical South America, from Colombia, Trinidad and Tobago south to Peru, Bolivia and central Brazil. Its habitat is forest and semi-open country. Although common, it is persecuted as an agricultural pest and by capture for the pet trade (over 66,000 captured from 1981 to 1985). It is also hunted as a food source. Introduced breeding populations have been reported in Puerto Rico and Tenerife in the Canary Islands. Taxonomy The orange-winged amazon was formally described in 1766 by the Swedish naturalist Carl Linnaeus in the twelfth edition of his ''Systema Naturae'' He placed it with all the other parrots in the genus ''Psittacus'' and coined the binomial name ''Psittacus amazonicus''. Linnaeus cited the 1760 description by the French zoologist Mathurin Jacques Brisson. Brisson used the French name "Le Perroquet ...

Wing-speculum
The speculum is a patch, often distinctly coloured, on the secondary wing feathers, or ''remiges'', of some birds. Examples of the colour(s) of the speculum in a number of ducks are: * Common teal and green-winged teal: Iridescent green edged with buff. * Blue-winged teal: Iridescent green. The species' common name comes from the sky-blue wing coverts. * Crested duck and bronze-winged duck: Iridescent purple-bronze, edged white. * Pacific black duck: Iridescent green, edged light buff. * Mallard: Iridescent purple-blue with white edges. * American black duck: Iridescent violet bordered in black and may have a thin white trailing edge. * Northern pintail: Iridescent green in male and brown in female, both are white on trailing edge. * Gadwall: Both sexes have white inner secondaries. * Yellow-billed duck: Iridescent green or blue, bordered white. Bright wing speculums are also known from a number of other birds; among them are several parrots from the genus ''Amazona Amazon ...

Remiges
Flight feathers (''Pennae volatus'') are the long, stiff, asymmetrically shaped, but symmetrically paired pennaceous feathers on the wings or tail of a bird; those on the wings are called remiges (), singular remex (), while those on the tail are called rectrices (), singular rectrix (). The primary function of the flight feathers is to aid in the generation of both thrust and lift, thereby enabling flight. The flight feathers of some birds have evolved to perform additional functions, generally associated with territorial displays, courtship rituals or feeding methods. In some species, these feathers have developed into long showy plumes used in visual courtship displays, while in others they create a sound during display flights. Tiny serrations on the leading edge of their remiges help owls to fly silently (and therefore hunt more successfully), while the extra-stiff rectrices of woodpeckers help them to brace against tree trunks as they hammer on them. Even flightless birds ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amazona Barbadensis -pet-upper Body-4-3c
Amazon parrots are parrots in the genus ''Amazona''. They are medium-sized, short-tailed parrots native to the Americas, with their range extending from South America to Mexico and the Caribbean. ''Amazona'' is one of the 92 genera of parrots that make up the order Psittaciformes and is in the family Psittacidae, one of three families of true parrots. It contains about thirty species. Most amazons are predominantly green, with accenting colors that depend on the species, and they can be quite vivid. They feed primarily on seeds, nuts, and fruits, supplemented by leafy matter. Many amazons have the ability to mimic human speech and other sounds. Partly because of this, they are popular as pets or companion parrots, and a small industry has developed in breeding parrots in captivity for this market. This popularity has led to many parrots being taken from the wild to the extent that some species have become threatened. The United States and the European Union have made the capt ...

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] |
Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...

Georges-Louis Leclerc, Comte De Buffon
Georges-Louis Leclerc, Comte de Buffon (; 7 September 1707 – 16 April 1788) was a French naturalist, mathematician, cosmologist, and encyclopédiste. His works influenced the next two generations of naturalists, including two prominent French scientists Jean-Baptiste Lamarck and Georges Cuvier. Buffon published thirty-six quarto volumes of his ''Histoire Naturelle'' during his lifetime, with additional volumes based on his notes and further research being published in the two decades following his death. Ernst Mayr wrote that "Truly, Buffon was the father of all thought in natural history in the second half of the 18th century".Mayr, Ernst 1981. ''The Growth of Biological Thought''. Cambridge: Harvard. p 330 Credited with being one of the first naturalists to recognize ecological succession, he was later forced by the theology committee at the University of Paris to recant his theories about geological history and animal evolution because they contradicted the Biblical na ...
