Formicariidae
Formicariidae is a family of smallish passerine birds of subtropical and tropical Central and South America known as formicariids. They are between in length, and are related to the antbirds, Thamnophilidae, and gnateaters, Conopophagidae. This family contains probably (see below) some 12 species in two fairly small genera. These are forest birds that tend to feed on insects at or near the ground. Most are drab in appearance with shades of (rusty) brown, black, and white being their dominant tones. Compared to other birds that specialize in following ants, this family is the most tied to the ground. The long, powerful legs (which lend the birds a distinctive upright posture) and an essentially vestigial tail aid this lifestyle. They lay two or three eggs in a nest in a tree, both sexes incubating. Systematics The antthrushes in the genera ''Formicarius'' and ''Chamaeza'' are similar in appearance to small rails. Their sexes are alike in plumage, and they walk like starlings. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Pittasoma
''Pittasoma'' is a genus of birds in the gnateater family. Its two members breed in subtropical or tropical moist forest in South and Central America, specifically the Chocó, and Panama and Costa Rica. Formerly placed in the family Formicariidae, they were reclassified to Conopophagidae following analysis of mtDNA cytochrome ''b'' and NADH dehydrogenase subunit 2 sequences (Rice, 2005a,b). The association between the genus ''Pittasoma'' and the 'traditional' gnateaters is also supported by traits in their natural history, morphology, vocalizations (Rice, 2005a). They are round, short-tailed, and long-legged birds, 16–19 cm (6-7½ inches) in length, making them the largest members of the gnateater family. These terrestrial birds are quite upright when standing. Sexes differ in plumage, but sexual dichromatism is less pronounced than in most members of the other gnateater genus, '' Conopophaga''. They are insectivorous. Species References *Rice, Nathan H. (2005a): Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grallariidae
Grallariidae is a family of smallish passerine birds of subtropical and tropical Central and South America known as antpittas. They are between 10 and 20 cm (4–8 in) in length, and are related to the antbirds, Thamnophilidae, and gnateaters, Conopophagidae. They were also formerly placed in the Formicariidae, but studies by Rice (2005) indicated a distinct family was supported. Both the North American and South American committees of the AOU recognized the family soon after. This family contains probably (see below) 68 species in one large and four fairly small genera. These are forest birds that tend to feed at or near the ground since many are specialist ant eaters. Most are drab in appearance with shades of (rusty) brown, black, and white being their dominant tones. Compared to other birds that specialize in following ants, this family is the most tied to the ground. The long, powerful legs (which lend the birds a distinctive upright posture) and an essentially ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gnateater
The gnateaters are a bird family, Conopophagidae, consisting of ten small passerine species in two genera, which occur in South and Central America. The family was formerly restricted to the gnateater genus ''Conopophaga''; analysis of mtDNA cytochrome ''b'' and NADH dehydrogenase subunit 2 sequences (Rice 2005a,b) indicates that the "antpittas" of the genus ''Pittasoma'' also belong in this family. The association between this genus and ''Conopophaga'' is also supported by traits in their natural history, morphology, and vocalizations (Rice, 2005a). The members of this family are very closely related to the antbirds and less closely to the antpittas and tapaculos. Due to their remote and dim habitat, gnateaters are a little-studied and poorly known family of birds, though they are often sought after by birdwatchers. Description They are round, short-tailed, and long-legged birds, about 12–19 cm (5–7½ inches) in length, with ''Pittasoma'' being larger than ''Conopop ...

Striated Antthrush
The striated antthrush (''Chamaeza nobilis'') is a species of bird in the family Formicariidae. It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru. Its natural habitat is subtropical or tropical moist lowland forests. The striated antthrush was described by the English ornithologist and bird artist John Gould John Gould (; 14 September 1804 – 3 February 1881) was an English ornithologist. He published a number of monographs on birds, illustrated by plates produced by his wife, Elizabeth Gould, and several other artists, including Edward Lear, ... in 1855 and given its current binomial name ''Chamaeza nobilis''.

Chamaeza
''Chamaeza'' is a genus of South American birds in the family Formicariidae. The genus was erected by the Irish zoologist Nicholas Aylward Vigors in 1825 with the cryptic antthrush (''Chamaeza meruloides'') 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 specime ....

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.

Formicarius (bird)
''Formicarius'' is a genus of passerine birds in the family Formicariidae. These birds are all found in the tropical New World, from southern Mexico south to Central America and northern South America. All are named as ''antthrushes'', and are insectivorous forest birds. They are largely terrestrial, feeding mainly on the ground on ants and other insects. Taxonomy The genus ''Formicarius'' was introduced by the Dutch naturalist Pieter Boddaert in 1783 in his catalogue of the ten volumes of hand-coloured plates that had been engraved by François-Nicolas Martinet. The plates were produced to accompany Georges-Louis Leclerc, Comte de Buffon's '' Histoire Naturelle des Oiseaux''. The type species was subsequently designated as the rufous-capped antthrush (''Formicarius colma'') by the English zoologist George Robert Gray George Robert Gray FRS (8 July 1808 – 6 May 1872) was an English zoologist and author, and head of the ornithological section of the British Museum, now ...

Rhinocrypta
The crested gallito (''Rhinocrypta lanceolata'') is a species of bird in the family Rhinocryptidae. It is found in Argentina, Bolivia, and Paraguay. Taxonomy and systematics The crested gallito is the only species in its genus. Two subspecies are recognized, the nominate ''Rhinocrypta lanceolata lanceolata'' and ''R. l. saturata'', which was described in 1939. Description The crested gallito is long. The male weighs and the female . It is an unusual tapaculo, having long crown feathers that it often erects as a crest and even bends forward. It also has a long tail that it cocks upward. The nominate subspecies' head is cinnamon with white streaks, its upper parts including wings and tail olive gray. The throat and chest are pale gray, the sides of the breast chestnut, and the lower belly olive gray. ''R. l. saturata'' is similar but all of the colors are darker.Krabbe, N. and T. S.

Type Genus
In biological taxonomy, the type genus is the genus which defines a biological family and the root of the family name. Zoological nomenclature According to the International Code of Zoological Nomenclature, "The name-bearing type of a nominal family-group taxon is a nominal genus called the 'type genus'; the family-group name is based upon that of the type genus." Any family-group name must have a type genus (and any genus-group name must have a type species, but any species-group name may, but need not, have one or more type specimens). The type genus for a family-group name is also the genus that provided the stem to which was added the ending -idae (for families). :Example: The family name Formicidae has as its type genus the genus ''Formica'' Linnaeus, 1758. Botanical nomenclature In botanical nomenclature, the phrase "type genus" is used, unofficially, as a term of convenience. In the '' ICN'' this phrase has no status. The code uses type specimens for ranks up to fam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paraphyletic
In taxonomy (general), taxonomy, a group is paraphyletic if it consists of the group's most recent common ancestor, last common ancestor and most of its descendants, excluding a few Monophyly, monophyletic subgroups. The group is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic group (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of Synapomorphy and apomorphy, synapomorphies and symplesiomorphy, symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term was coined by Willi Hennig to apply to well-known taxa like Reptilia (reptiles) which, as commonly named and traditionally defined, is paraphyletic with respect to mammals and birds. Reptilia contains the last common ancestor of reptiles a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
