Spix's Warbling Antbird
Spix's warbling antbird (''Hypocnemis striata'') is a species of bird in the family Thamnophilidae. Spix's warbling antbird was described and illustrated by the German naturalist Johann Baptist von Spix in 1825 and given the binomial name ''Thamnophilus striatus''. The current genus ''Hypocnemis'' was introduced in 1847. Until recently, it was considered a subspecies of the Guianan warbling antbird (''Hypocnemis cantator''), but based on vocal differences and to a lesser degree differences in plumage, it is now treated as separate species. There are three subspecies: * ''Hypocnemis striata implicata'' Zimmer, JT, 1932 – west central Amazonian Brazil * ''Hypocnemis striata striata'' (von Spix, 1825) – central Amazonian Brazil * ''Hypocnemis striata affinis'' Zimmer, JT, 1932 – east central Amazonian Brazil The westernmost population is likely to represent an undescribed subspecies. Spix's warbling antbird is found at lower levels in humid forest in the south-eastern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Baptist Von Spix
Johann Baptist Ritter von Spix (9 February 1781 – 13 March 1826) was a German natural history, biologist. From his expedition to Brazil, he brought to Germany a large variety of specimens of plants, insects, mammals, birds, amphibians and fish. They constitute an important basis for today's National Zoological Collection in Munich. Numerous examples of his ethnographic collections, such as dance masks and the like, are now part of the collection of the Museum Five Continents, Museum of Ethnography in Munich. Biography Spix was born in Höchstadt, in present-day Middle Franconia, as the seventh of eleven children. His childhood home is the site of the Spix Museum, open to the public since 2004. He studied philosophy in Bamberg and graduated with a doctoral degree. Later he studied theology in Würzburg. After attending lectures of the young professor Friedrich Wilhelm Joseph Schelling, F. W. J. Schelling, Spix became interested in nature. He quit his theology studi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird
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. B ...

Thamnophilidae
The antbirds are a large passerine bird family, Thamnophilidae, found across subtropical and tropical Central and South America, from Mexico to Argentina. There are more than 230 species, known variously as antshrikes, antwrens, antvireos, fire-eyes, bare-eyes and bushbirds. They are related to the antthrushes and antpittas (family Formicariidae), the tapaculos, the gnateaters and the ovenbirds. Despite some species' common names, this family is not closely related to the wrens, vireos or shrikes. Antbirds are generally small birds with rounded wings and strong legs. They have mostly sombre grey, white, brown and rufous plumage, which is sexually dimorphic in pattern and colouring. Some species communicate warnings to rivals by exposing white feather patches on their backs or shoulders. Most have heavy bills, which in many species are hooked at the tip. Most species live in forests, although a few are found in other habitats. Insects and other arthropods from the most impor ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Binomial Name
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Hypocnemis
''Hypocnemis'' is a genus of passerine birds in the family Thamnophilidae. They are resident breeders in tropical Central and South America. The genus ''Hypocnemis'' was introduced by the German ornithologist Jean Cabanis in 1847. The name combines the Ancient Greek words ''hupo'' "somewhat like" and ''knēmis'' "leggings". The type species was subsequently designated as the Guianan warbling antbird. The genus contains eight species: * Guianan warbling antbird, ''Hypocnemis cantator'' * Imeri warbling antbird, ''Hypocnemis flavescens'' * Peruvian warbling antbird, ''Hypocnemis peruviana'' * Yellow-breasted warbling antbird, ''Hypocnemis subflava'' * Rondonia warbling antbird, ''Hypocnemis ochrogyna'' * Spix's warbling antbird, ''Hypocnemis striata'' * Manicoré warbling antbird, ''Hypocnemis rondoni'' * Yellow-browed antbird, ''Hypocnemis hypoxantha'' The warbling antbird has traditionally been considered a single polytypic species, but recent evidence has led to it ...

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] |
Guianan Warbling Antbird
The Guianan warbling antbird (''Hypocnemis cantator'') is an insectivorous bird in the antbird family, Thamnophilidae. It is found at lower levels in humid forest in the Guianas, far eastern Venezuela (with Guyana), and north-eastern Brazil (north of the Amazon River and east of the lower Negro River and the Branco River). Taxonomy The French polymath Georges-Louis Leclerc, Comte de Buffon described the Guianan warbling antbird in his ''Histoire Naturelle des Oiseaux'' in 1779. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the ''Planches Enluminées D'Histoire Naturelle'' which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Buffon did not include a scientific name with his description but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name ''Formicarius cantatar'' in his catalogue of the ''Planches Enluminées''. The specific name is from the Latin ''cantator'' "a si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

John Todd Zimmer
John Todd Zimmer (February 28, 1889 in Bridgeport, Ohio – January 6, 1957 in White Plains, New York) was a leading American ornithologist. A graduate of University of Nebraska-Lincoln, he took an early interest in both entomology and ornithology. From 1913 he worked as an agricultural adviser in the Philippines and later New Guinea, during which time he made important collections of bird specimens. After his return to America he joined the staff of the Field Museum of Natural History, in which role he compiled a ''Catalog of the Ayer Ornithological Library'', and participated in expeditions to Africa and Peru. In 1930 Frank Chapman recruited him as Associate Curator of Birds at the American Museum of Natural History in New York, where he remained for the rest of his life. He made systematic revisions of the taxonomy of the birds of Peru and their relatives in other parts of South America, and in his later years combined this with studies of New World flycatchers, preparing the s ...
