Warbling Antbird
The warbling antbird is a complex consisting of six species of antbirds that until recently were considered a single species found throughout the Amazon in South America. Based on vocal differences and to a lesser degree differences in plumages, it has been recommended treating them as separate 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 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 ''T ... (''Hypocnemis striata'').

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency of Norway), Pa ...

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.

Peruvian Warbling Antbird
The Peruvian warbling antbird (''Hypocnemis peruviana'') is a species of bird in the family Thamnophilidae.

Imeri Warbling Antbird
The Imeri warbling antbird (''Hypocnemis flavescens'') is a species of bird in the family Thamnophilidae. It is found at lower levels in humid forest in southern Venezuela, south-eastern Colombia and north-western Brazil (west of the Branco River).

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 ...

Chordata
A chordate () is an animal of the phylum Chordata (). All chordates possess, at some point during their larval or adult stages, five synapomorphies, or primary physical characteristics, that distinguish them from all the other taxa. These five synapomorphies include a notochord, dorsal hollow nerve cord, endostyle or thyroid, pharyngeal slits, and a post-anal tail. The name “chordate” comes from the first of these synapomorphies, the notochord, which plays a significant role in chordate structure and movement. Chordates are also Bilateral symmetry, bilaterally symmetric, have a coelom, possess a circulatory system, and exhibit Metameric, metameric segmentation. In addition to the morphological characteristics used to define chordates, analysis of genome sequences has identified two conserved signature indels (CSIs) in their proteins: cyclophilin-like protein and mitochondrial inner membrane protease ATP23, which are exclusively shared by all vertebrates, tunicates and cep ...

Antbird
The antbirds are a large passerine bird family (biology), family, Thamnophilidae, found across subtropical and tropical Central and South America, from Mexico to Argentina. There are List of antbirds, 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 Ovenbird (family), 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 sexual dimorphism, 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 beak, bills, which in many species are hooked at the tip. Most species live in forests, although a few ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
