Black-and-gold Cotinga
The black-and-gold cotinga (''Lipaugus ater'') is a species of bird in the family Cotingidae. It is endemic to humid Atlantic Forest in the highlands of the Serra do Mar in south-eastern Brazil. It is threatened by habitat loss, but remains common within several national parks, e.g. Serra dos Órgãos and Itatiaia. Males are highly vocal, and their loud, piercing whistle is frequently heard. It is strongly sexually dimorphic. Except for a bright yellow wing-speculum, males are superficially similar to the male common blackbird, while the far less conspicuous females are overall olive. The female resemble both sexes of the only other member of the genus, the grey-winged cotinga, but is larger, has a thicker bill, and yellowish-olive (not grey) remiges. This species was formerly placed in the genus ''Tijuca''. A molecular phylogenetic study published in 2014 found the ''Tijuca'' was embedded within the genus ''Lipaugus ''Lipaugus'' is a genus of birds in the family Cotingidae ...

André Étienne Justin Pascal Joseph François D'Audebert De Férussac
André — sometimes transliterated as Andre — is the French and Portuguese form of the name Andrew, and is now also used in the English-speaking world. It used in France, Quebec, Canada and other French-speaking countries. It is a variation of the Greek name ''Andreas'', a short form of any of various compound names derived from ''andr-'' 'man, warrior'. The name is popular in Norway and Sweden.

Common Blackbird
The common blackbird (''Turdus merula'') is a species of true thrush. It is also called the Eurasian blackbird (especially in North America, to distinguish it from the unrelated New World blackbirds), or simply the blackbird where this does not lead to confusion with a local species. It breeds in Europe, Asiatic Russia, and North Africa, and has been introduced to Australia and New Zealand. It has a number of subspecies across its large range; a few of the Asian subspecies are sometimes considered to be full species. Depending on latitude, the common blackbird may be resident, partially migratory, or fully migratory. The adult male of the common blackbird (''Turdus merula merula'', the nominate subspecies), which is found throughout most of Europe, is all black except for a yellow eye-ring and bill and has a rich, melodious song; the adult female and juvenile have mainly dark brown plumage. This species breeds in woods and gardens, building a neat, cup-shaped nest, bound ... [...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 sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of The Atlantic Forest
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] |
Lipaugus
''Lipaugus'' is a genus of birds in the family Cotingidae. Taxonomy The genus was introduced in 1828 by the German zoologist Friedrich Boie in 1828. Boie spelled the genus name as ''Lipangus'' but this was corrected to ''Lipaugus''. The name comes from the Greek ''lipaugēs'', meaning "dark" or "devoid of light". The type species was designated by George Gray in 1840 as the screaming piha. The genus contains nine species. Two former ''Lipaugus'' species are now in the genus'' Snowornis ''Snowornis'' is a genus of birds in the family Cotingidae.

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree. History The theoretical ...

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 bir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Olive (color)
Olive is a dark yellowish-green color, like that of unripe or green olives. As a color word in the English language, it appears in late Middle English. Shaded toward gray, it becomes olive drab. Variations Olivine Olivine is the typical color of the mineral olivine. The first recorded use of ''olivine'' as a color name in English was in 1912. Olive drab Olive drab is variously described as a "dull olive-green colour" (''Oxford English Dictionary'');''Oxford English Dictionary'', 5th Edition, 1982 "a shade of greenish-brown" (''Webster's New World Dictionary''); "a dark gray-green" (''MacMillan English dictionary''); "a grayish olive to dark olive brown or olive gray" (''American Heritage Dictionary''); or "A dull but fairly strong gray-green color" (''Collins English Dictionary''). It was widely used as a camouflage color for uniforms and equipment in the armed forces, particularly by the U.S. Army during the Second World War. The first recorded use of ''olive ...

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 ...
