Blue-cheeked Parrot
The blue-cheeked amazon (''Amazona dufresniana''), also known as blue-cheeked parrot or Dufresne's amazon, is a parrot found in northeast South America in eastern Venezuela, the Guianas and possibly far northern Brazil. It lives in forest and savanna woodlands up to . Description It is about long. Its coloring is mostly green, with blue cheeks from around the eye to the neck (less on young), a yellow-orange wing speculum, a yellowish crown, and orange lores (the region between the eye and bill on the side of a bird's head). The binomial of this species commemorates the French zoologist Louis Dufresne. Now monotypic, it formerly included the red-browed amazon as a 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.

George Shaw (biologist)
George Kearsley Shaw (10 December 1751 – 22 July 1813) was an English botanist and zoologist. Life Shaw was born at Bierton, Buckinghamshire, and was educated at Magdalen Hall, Oxford, receiving his M.A. in 1772. He took up the profession of medical practitioner. In 1786 he became the assistant lecturer in botany at the University of Oxford. He was a co-founder of the Linnean Society in 1788, and became a fellow of the Royal Society in 1789. In 1791 Shaw became assistant keeper of the natural history department at the British Museum, succeeding Edward Whitaker Gray as keeper in 1806. He found that most of the items donated to the museum by Hans Sloane were in very bad condition. Medical and anatomical material was sent to the museum at the Royal College of Surgeons, but many of the stuffed animals and birds had deteriorated and had to be burnt. He was succeeded after his death by his assistant Charles Konig. Works Shaw published one of the first English descriptions with s ...

Louis Dufresne
Louis Dufresne (18 January 1752, Champien, near Peronne – 11 October 1832) was a French ornithologist and taxidermist. Louis Dufresne was one of the naturalists on board the ''Astrolabe'', which accompanied by the ''Boussole'', left Brest in August 1785 on a voyage of discovery. The ships went first to Madeira and Tenerife, then to Trinidad and then to the coast of Brazil (including Santa Catarina Island). Rounding Cape Horn the expedition landed at Concepción and on to the Sandwich Islands and then sailed north along the coast of north-west America to Alaska. In 1786, the expedition resumed this time visiting Monterey before crossing the Pacific to land in Macao in China. In 1787 the boats returned to France. Six years later in 1793, Dufresne became a taxidermist and curator at Museum d'Histoire Naturelle. His work included the classification and arrangement of collections of invertebrates as well as vertebrates and he visited many parts of the world on behalf of the Museum. ...

Birds Of The Guianas
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. Bir ...

Parrots Of South America
Parrots, also known as psittacines (), are birds of the roughly 398 species in 92 genera comprising the order Psittaciformes (), found mostly in tropical and subtropical regions. The order is subdivided into three superfamilies: the Psittacoidea ("true" parrots), the Cacatuoidea (cockatoos), and the Strigopoidea (New Zealand parrots). One-third of all parrot species are threatened by extinction, with higher aggregate extinction risk ( IUCN Red List Index) than any other comparable bird group. Parrots have a generally pantropical distribution with several species inhabiting temperate regions in the Southern Hemisphere, as well. The greatest diversity of parrots is in South America and Australasia. Characteristic features of parrots include a strong, curved bill, an upright stance, strong legs, and clawed zygodactyl feet. Many parrots are vividly coloured, and some are multi-coloured. Most parrots exhibit little or no sexual dimorphism in the visual spectrum. They form the mos ...

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] |
Red-browed Amazon
The red-browed amazon (''Amazona rhodocorytha'') is a species of parrot in the family Psittacidae. It is endemic to Atlantic Forest in eastern Brazil. It has been considered a subspecies of the blue-cheeked amazon (''Amazona dufresniana''), but today all major authorities consider them separate species. It is threatened both by habitat loss and by being captured for the trade in wild parrots. Description The red-browed amazon has a bright red crown fading to purplish-brown at the back. The cheeks and throat are blue and the wing and body plumage is green with dark markings on the back of the neck. Black and red patches can be seen on the wings when they are spread and the tail feathers have red markings and are tipped with yellow. The beak and legs are grey and the iris of the eye is orange-brown. Distribution and habitat The red-browed amazon is endemic to tropical forests in eastern Brazil. It used to be widespread across the region but is now restricted to some of the larg ... [...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. ...

Lore (anatomy)
The lore (adj. loreal) is the region between the eyes and nostrils of birds, reptiles, and amphibians. Ornithology In ornithology, the lore is the region between the eye and bill on the side of a bird's head. This region is sometimes featherless, and the skin may be tinted, as in many species of the cormorant family. This area, which is directly in front of the eye, features a "loral stripe" in many bird species including the red-capped plover. Herpetology In amphibians and reptiles, lore pertains to the regions immediately adjacent to the eyes and between the eyes and nostrils. These are analogous to the lore on birds which corresponds to the region between the eye and the beak. In snakes and reptiles, a loreal scale also refers to the scales which lie between the eye and the nostril. In crotaline snakes (pit vipers), loreal pits are present on either side of the head.Campbell JA, Lamar WW. 2004. The Venomous Reptiles of the Western Hemisphere. 2 volumes. Comstock Publishi ...

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 ...

Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to '' Britannica'', there exists four savanna forms; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in for ...
