Grey Antbird
The grey antbird (''Cercomacra cinerascens'') is a species of bird in the antbird family Thamnophilidae. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. Its natural habitat is subtropical or tropical moist lowland forests. The grey antbird is in length. The male is grey with a darker grey tail. It has white spotting on the and broad white spots near the tips of the tail feathers. The female is olive brown above, pale ochre brown below and has a darker brown tail. The white spotting on the wings and on the tail of the female is similar to that on the male. Taxonomy The grey antbird was described by the English zoologist Philip Sclater in 1857 from a specimen obtained near the Rio Napo in Ecuador. He coined the binomial name ''Formicivora cinerascens''. The specific epithet is Late Latin meaning "ashen". This antbird is now placed in the genus ''Cercomacra'' that was introduced by Sclater in 1858. Four subspec ...

Philip Sclater
Philip Lutley Sclater (4 November 1829 – 27 June 1913) was an England, English lawyer and zoologist. In zoology, he was an expert ornithologist, and identified the main zoogeographic regions of the world. He was Secretary of the Zoological Society of London for 42 years, from 1860–1902. Early life Sclater was born at Tangier Park, in Wootton St Lawrence, Hampshire, where his father William Lutley Sclater had a country house. George Sclater-Booth, 1st Baron Basing was Philip's elder brother. Philip grew up at Hoddington House where he took an early interest in birds. He was educated in school at Twyford and at thirteen went to Winchester College and later Corpus Christi College, Oxford where he studied scientific ornithology under Hugh Edwin Strickland. In 1851 he began to study law and was admitted a Fellow of Corpus Christi College. In 1856 he travelled to America and visited Lake Superior and the upper St. Croix River (Wisconsin–Minnesota), St. Croix River, cano ...

Rio Napo
The Napo River ( es, Río Napo) is a tributary to the Amazon River that rises in Ecuador on the flanks of the east Andean volcanoes of Antisana, Sincholagua and Cotopaxi. The total length is . The river drains an area of . The mean annual discharge is ( Mazán). Geography Before it reaches the plains it receives a great number of small streams from impenetrable, saturated and much broken mountainous districts, where the dense and varied vegetation seems to fight for every piece of ground. From the north it is joined by the Coca River, having its sources in the gorges of Cayambe volcano on the equator, and also a powerful river, the Aguarico having its headwaters between Cayambe and the Colombia frontier. From the west, it receives a secondary tributary, the Curaray, from the Andean slopes, between Cotopaxi and the Tungurahua volcano. From its Coca branch to the mouth of the Curaray the Napo is full of snags and shelving sandbanks and throws out numerous canoes among jung ...

Taxa Named By Philip Sclater
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1857
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. Birds ...

Carl Eduard Hellmayr (29 January 1878 in Vienna, Austria – 24 February 1944 in Orselina, Switzerland) was an Austrian ornithologist. Biography Hellmayr was born in Vienna and studied at the University of Vienna, although he did not complete his degree. After his studies he worked in Vienna, Munich, Berlin, Paris, Tring (England), and Chicago.

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] |
Cercomacra
''Cercomacra'' is a genus of passerine birds in the family Thamnophilidae. The genus was erected by the English zoologist Philip Sclater in 1858. The type species was subsequently designated as the Rio de Janeiro antbird. The genus contains seven species: * Manu antbird (''Cercomacra manu'') * Rio de Janeiro antbird (''Cercomacra brasiliana'') * Grey antbird (''Cercomacra cinerascens'') * Mato Grosso antbird (''Cercomacra melanaria'') * Bananal antbird (''Cercomacra ferdinandi'') * Jet antbird (''Cercomacra nigricans'') * Rio Branco antbird (''Cercomacra carbonaria'') The genus formerly included additional species but when a molecular phylogenetic study published in 2014 found that ''Cercomacra'' was polyphyletic the genus was split to create two monophyletic genera and six species were moved to the newly erected genus ''Cercomacroides ''Cercomacroides'' is a genus of passerine birds in the family Thamnophilidae.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
