Green-thighed Parrot
The green-thighed parrot (''Pionites leucogaster''), also known as the eastern white-bellied parrot, is a species of parrot in the family Psittacidae. The species was previously known as the white-bellied parrot (or white-bellied caique in aviculture) and contained three subspecies including the nominate race, but recent morphological work suggested the species should be split into three:del Hoyo, J., Collar, N. & Kirwan, G.M.

Heinrich Kuhl
Heinrich Kuhl (17 September 1797 – 14 September 1821) was a German naturalist and zoologist. Kuhl was born in Hanau (Hesse, Germany). Between 1817 and 1820, he was the assistant of professor Th. van Swinderen, docent natural history at the University of Groningen in Groningen (the Netherlands). In 1817, he published a monograph on bats, and in 1819, he published a survey of the parrots, ''Conspectus psittacorum''. He also published the first monograph on the petrels, and a list of all the birds illustrated in Daubenton's ''Planches Enluminées'' and with his friend Johan Coenraad van Hasselt (1797–1823) ''Beiträge zur Zoologie und vergleichenden Anatomie'' ("Contributions to Zoology and Comparative Anatomy") that were published at Frankfurt-am-Main, 1820. In 1820, he became assistant to Coenraad Jacob Temminck at the Leiden Rijksmuseum van Natuurlijke Historie. He then travelled to Java, then part of the colonial Netherlands East Indies, with his friend van Hasselt, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Birds Of Brazil
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] |
Birds Of The Brazilian Amazon
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] |
Pionites
Caique ( or ) refers to a group of four species of parrots in the genus ''Pionites'' endemic to the Amazon Basin in South America. Name The term "caique" is primarily used in aviculture, with ornithologists typically referring to them as the "black-headed parrot and "white-bellied parrot" (which is sometimes further split into three separate species - green-thighed parrot, yellow-tailed parrot and black-legged parrot) to describe the nominal species. They have historically been called the “seven-colored parrot”. They are relatively small and stocky, with a short, square tail and bright colors; this may be why they are referred to as “caique” based on the term for a similarly described Turkish vessel. Description The two primary nominal species are best distinguished by the black-headed caique's black crown; both have white “bellies”. Their typical weight is 150–170 grams, with the white-bellied species being the larger and heavier of the two nominal species. ...

Tannin
Tannins (or tannoids) are a class of astringent, polyphenolic biomolecules that bind to and precipitate proteins and various other organic compounds including amino acids and alkaloids. The term ''tannin'' (from Anglo-Norman ''tanner'', from Medieval Latin ''tannāre'', from ''tannum'', oak bark) refers to the use of oak and other bark in tanning animal hides into leather. By extension, the term ''tannin'' is widely applied to any large polyphenolic compound containing sufficient hydroxyls and other suitable groups (such as carboxyls) to form strong complexes with various macromolecules. The tannin compounds are widely distributed in many species of plants, where they play a role in protection from predation (acting as pesticides) and might help in regulating plant growth. The astringency from the tannins is what causes the dry and puckery feeling in the mouth following the consumption of unripened fruit, red wine or tea. Likewise, the destruction or modification of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iris (anatomy)
In humans and most mammals and birds, the iris (plural: ''irides'' or ''irises'') is a thin, annular structure in the eye, responsible for controlling the diameter and size of the pupil, and thus the amount of light reaching the retina. Eye color is defined by the iris. In optical terms, the pupil is the eye's aperture, while the iris is the diaphragm. Structure The iris consists of two layers: the front pigmented fibrovascular layer known as a stroma and, beneath the stroma, pigmented epithelial cells. The stroma is connected to a sphincter muscle ( sphincter pupillae), which contracts the pupil in a circular motion, and a set of dilator muscles ( dilator pupillae), which pull the iris radially to enlarge the pupil, pulling it in folds. The sphincter pupillae is the opposing muscle of the dilator pupillae. The pupil's diameter, and thus the inner border of the iris, changes size when constricting or dilating. The outer border of the iris does not change size. The constr ... [...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 ...

Amazônia National Park
The Amazônia National Park ( pt, Parque Nacional da Amazônia) was created in 1974, as a national park comprising 1,070,737 ha. It is situated in Itaituba and Trairão municipalities, Pará state, in the north region of Brazil. It is located in the watershed of the Tapajós River, about halfway between Manaus and Belém. It has expanded since its inception and now covers . It is a very biodiverse habitat and contains a wide range of animals and plants. The specific objectives of the park are the preservation of various Amazonic ecosystems, through scientific, educational and recreational means. Geography The park lies on either side of the Tapajós River. The habitat is dense lowland rain forest and there are areas of white-sand grasslands beside the upper reaches of the Tapajós. This river rises in the Precambrian crystalline shields area of ancient igneous rock and carries little sediment. The river acts as a barrier so that some of the animals and plants on one bank are not f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psittacidae
The family Psittacidae or holotropical parrots is one of three families of true parrots. It comprises the roughly 10 species of subfamily Psittacinae (the Old World or Afrotropical parrots) and 157 of subfamily Arinae (the New World or Neotropical parrots), as well as several species that have gone extinct in recent centuries. Some of the most iconic birds in the world are represented here, such as the blue-and-gold macaw among the New World parrots and the grey parrot among the Old World parrots. Distribution All of the parrot species in this family are found in tropical and subtropical zones and inhabit Mexico, Central and South America, the Caribbean islands, sub-Saharan Africa, the island of Madagascar, the Arabian Peninsula, Southeast Asia, Australia and Oceania. Two parrots, one extinct and the other extirpated, formerly inhabited the United States. Evolutionary history This family probably had its origin early in the Paleogene period, 66–23 million ...
