Common Scale-backed Antbird
The common scale-backed antbird (''Willisornis poecilinotus'') is a species of passerine bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. Taxonomy and systematics The common scale-backed antbird has a complicated taxonomic history. It was described and illustrated by the German ornithologist Jean Cabanis in 1847 and given the binomial name ''Hypocnemis poecilinotus''. The specific epithet is from the Ancient Greek ''poikilonōtos'' "with variegated back" (from ''poikilos'' "spotted" and ''nōton'' "back"). It was subsequently included in the genus ''Hylophylax'', but was found to not be closely related to the other species in the genus and then was briefly placed in genus ''Dichropogon''. This name is preoccupied by a genus of asilid flies (''Dichropogon'' Bezzi, 1910) so the current genus ''Willisornis'' was created for it. The common sc ...

Cordillera Del Cóndor
The Cordillera del Cóndor (Condor mountain range) is a mountain range in the eastern Andes that is shared by and part of the international border between Ecuador and Peru. The range extends approximately 150 km north to south and its maximum elevation reaches approximately 2,900m. The Río Santiago and Cenepa River flow along its eastern slopes on the Peruvian side. For over 160 years, the area of the border was in dispute, and sparked armed conflicts between the two countries in 1941, 1981 and 1995. After the border conflict of 1995, the two countries began diplomatic negotiations, resulting in the 1998 peace treaty that established the exact location of the international border. The Cordillera del Condor is an area of great interest to biology, possibly having the richest flora in any area of the same size on the South American continent, and is considered by Conservation International to be one of the most important biodiversity areas on the planet.

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roraima
Roraima (, ) is one of the 26 states of Brazil. Located in the country's North Region, it is the northernmost and most geographically and logistically isolated state in Brazil. It is bordered by the state of Pará to the southeast, Amazonas to the south and west, Venezuela to the north and northwest, and Guyana to the east.

Birdgloss
The following is a glossary of common English language terms used in the description of birds—warm-blooded vertebrates of the class Aves and the only living dinosaurs, characterized by , the ability to in all but the approximately 60 extant species of flightless birds, toothless, , the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart and a strong yet lightweight skeleton. Among other details such as size, proportions and shape, terms defining bird features developed and are used to describe features unique to the class—especially evolutionary adaptations that developed to aid flight. There are, for example, numerous terms describing the complex structural makeup of feathers (e.g., , and ); types of feathers (e.g., , and feathers); and their growth and loss (e.g., , and ). There are thousands of terms that are unique to the study of birds. This glossary makes no attempt to cover them all, concentrating on terms that might be found across de ...

Nominate 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] |
Xingu Scale-backed Antbird
The Xingu scale-backed antbird (''Willisornis vidua'') is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is endemic to Brazil. Taxonomy and systematics What is now the Xingu scale-backed antbird was long considered a subspecies of ''Willisornis poecilinotus'', which at the time was called the scale-backed antbird. When the Xingu scale-backed antbird was recognized as a separate species, the reduced ''W. poecilinotus'' was renamed the common scale-backed antbird. Even before the split the species had a complicated taxonomic history, being variously assigned to genera ''Hypocnemis'', ''Hylophylax'', and ''Dichropogon'' before the current ''Willisornis'' was created for it. It was described and illustrated by the German ornithologist Jean Cabanis in 1847 and given the binomial name ''Hypocnemis poecilinotus''.Remsen, J. V., Jr., J. I. Areta, E. Bonaccorso, S.

American Ornithological Society
The American Ornithological Society (AOS) is an ornithological organization based in the United States. The society was formed in October 2016 by the merger of the American Ornithologists' Union (AOU) and the Cooper Ornithological Society. Its members are primarily professional ornithologists, although membership is open to anyone with an interest in birds. The society publishes the two scholarly journals, ''The Auk'' and '' The Condor'' as well as the ''AOS Checklist of North American Birds''. In 2013, the American Ornithologists' Union announced a close partnership with the Cooper Ornithological Society, including joint meetings, a centralized publishing office, and a refocusing of their respective journals to increase efficiency of research. In October 2016, the AOU announced that it was ceasing to operate as an independent union and was merging with the Cooper Ornithological Society to create the American Ornithological Society.

Plumage
Plumage ( "feather") is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morphs. The placement of feathers on a bird is not haphazard, but rather emerge in organized, overlapping rows and groups, and these are known by standardized names. Most birds moult twice a year, resulting in a breeding or ''nuptial plumage'' and a ''basic plumage''. Many ducks and some other species such as the red junglefowl have males wearing a bright nuptial plumage while breeding and a drab ''eclipse plumage'' for some months afterward. The painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the ''juvenile plumage'' with an ''auxiliary formative plumage''; the second a month or so l ...
