Cercomacroides
''Cercomacroides'' is a genus of passerine birds in the family Thamnophilidae. The genus contains six species: * Willis's antbird (''Cercomacroides laeta'') * Parker's antbird (''Cercomacroides parkeri'') * Blackish antbird (''Cercomacroides nigrescens'') * Riparian antbird (''Cercomacroides fuscicauda'') * Dusky antbird (''Cercomacroides tyrannina'') * Black antbird (''Cercomacroides serva'') These species were formerly placed in the genus '' Cercomacra''. A molecular phylogenetic study published in 2014 found that ''Cercomacra'', as then defined, was polyphyletic. The genus was split to create monophyletic genera and six species were moved to the newly erected genus ''Cercomacroides'' with the dusky antbird as the type species In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen ...

Blackish Antbird
The blackish antbird (''Cercomacroides nigrescens'') is a species of passerine bird in the family Thamnophilidae. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Peru, and Suriname. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, and heavily degraded former forest. The blackish antbird was described by the German ornithologists Jean Cabanis and Ferdinand Heine in 1860 and given the binomial name ''Percnostola nigrescens''. The specific epithet is from the Latin ''nigrescens'' "blackish" (from ''nigrescere '' "to become black"). The antbird was subsequently included in the genus ''Cercomacra'' but a molecular phylogenetic study published in 2014 found that ''Cercomacra'' was polyphyletic. The genus was split to create two monophyletic genera and six species including the blackish antbird were moved to the newly erected genus ''Cercomacroides ''Cercomacroides'' is a genus of passerine birds ...

Riparian Antbird
The riparian antbird (''Cercomacroides fuscicauda'') is a species of passerine bird in the family Thamnophilidae. It is found in southern Colombia, eastern Ecuador, eastern Peru, northern Bolivia and southwestern Amazonian Brazil. Its natural habitats are subtropical or tropical moist lowland forests, and adjacent thickets on sandbars and riverbanks. The riparian antbird used to be considered conspecific with the blackish antbird but the two taxa were split based their different vocalization. The riparian antbird was formerly included in the genus ''Cercomacra''. A molecular phylogenetic study published in 2014 found that ''Cercomacra'', as then defined, was polyphyletic. The genus was split to create two monophyletic genera and six species including the riparian antbird were moved to the newly erected genus ''Cercomacroides ''Cercomacroides'' is a genus of passerine birds in the family Thamnophilidae.

Black Antbird
The black antbird (''Cercomacroides serva'') is a species of passerine bird in the family Thamnophilidae. It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru. Its natural habitat is subtropical or tropical moist lowland forests. The black antbird was described by the English zoologist Philip Sclater in 1858 and given the binomial name ''Pyriglena serva''. It was formerly included in the genus ''Cercomacra'' 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 including the black antbird were moved to the newly erected genus ''Cercomacroides ''Cercomacroides'' is a genus of passerine birds in the family Thamnophilidae.

Willis's Antbird
Willis's antbird (''Cercomacroides laeta''), also known as the laeta antbird, is a species of bird in the family Thamnophilidae. It is endemic to Brazil. It was formerly considered a subspecies of dusky antbird. Its natural habitats are subtropical or tropical moist lowland forests and heavily degraded former forest. Willis's antbird was described by the American ornithologist W. E. Clyde Todd in 1920 as a subspecies of the dusky antbird and given the trinomial name ''Cercomacra tyrannina laeta''. A 1997 study found that Willis's antbird differed from the dusky antbird in both plumage and voice and as a result, Willis's antbird was promoted to species status. The common name commemorates the American ornithologist Edwin O'Neill Willis. A molecular phylogenetic study published in 2014 found that '' Cercomacra'' was polyphyletic. The genus was split to create two monophyletic genera and six species including Willis's antbird were moved to the newly erected genus ''Cercomacroides ...

Dusky Antbird
The dusky antbird or tyrannine antbird (''Cercomacroides tyrannina'') is a passerine bird in the antbird family. It is a resident breeder in tropical Central and South America from southeastern Mexico southwards to western Ecuador, and Amazonian Brazil. Taxonomy The dusky antbird was described by the English zoologist Philip Sclater in 1855 and given the binomial name ''Pyriglena tyrannina''. The species was subsequently placed in the genus '' Cercomacra'' but a molecular phylogenetic study published in 2014 found that ''Cercomacra'', as then defined, was polyphyletic. The genus was split to create two monophyletic genera and six species including the dusky antbird were moved to the newly erected genus '' Cercomacroides''. Habitat This is a common bird in the understory thickets of wet forest, especially at edges and clearings, and in adjacent tall second growth. The female lays two reddish-brown-spotted white eggs, which are incubated by both sexes, in a small, deep, plant fibr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parker's Antbird
Parker's antbird (''Cercomacroides parkeri'') is a species of passerine bird in the family Thamnophilidae. It is endemic to Colombia. Parker's antbird was described by the American ornithologist Gary Graves in 1997 and given the binomial name ''Cercomacra parkeri''. The specific name was chosen to honour the American ornithologist Theodore A. Parker III (1953—1993). A molecular phylogenetic study published in 2014 found that the genus ''Cercomacra'' was polyphyletic. The genus was therefore split to create two monophyletic genera and six species including Parker's antbird 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 ...

Passerine
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped'), which includes more than half of all bird species. Sometimes known as perching birds, passerines are distinguished from other orders of birds by the arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest clade of birds and among the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al. (2003Evolution, biogeography, and patterns of diversification in passerine birds ''J. Avian Biol'', 34:3–15.Selvatti, A.P. et al. (2015"A Paleogene origin for crown passerines and the diversification of the Oscines in the New World" ''Molecular Phylogenetics and Evolution'', 88:1–15. Passerines are divided into three clades: Acanthisitti (New Zealand wrens), Tyranni (suboscines), and Passeri (oscines or songbirds). The passeri ...

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 ...

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.
