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] |

Grallaria
''Grallaria'' is a large genus of Neotropical birds in the antpitta family Grallariidae. The genus was introduced by the French ornithologist Louis Jean Pierre Vieillot in 1816 with the variegated antpitta (''Grallaria varia'') as the type species. The genus name is from New Latin ''grallarius'' meaning "stilt-walker". Species The genus contains the following 45 species * Undulated antpitta, ''Grallaria squamigera'' * Giant antpitta, ''Grallaria gigantea'' * Great antpitta, ''Grallaria excelsa'' * Variegated antpitta, ''Grallaria varia'' * Scaled antpitta, ''Grallaria guatimalensis'' * Moustached antpitta, ''Grallaria alleni'' * Táchira antpitta, ''Grallaria chthonia'' * Plain-backed antpitta, ''Grallaria haplonota'' * Ochre-striped antpitta, ''Grallaria dignissima'' * Elusive antpitta, ''Grallaria eludens'' * Santa Marta antpitta, ''Grallaria bangsi'' * Chestnut-crowned antpitta, ''Grallaria ruficapilla'' * Cundinamarca antpitta, ''Grallaria kaestneri'' * Watkins's ant ...

Myrmothera
''Myrmothera'' is a genus of birds belonging to the family Grallariidae. Established by French ornithologist Louis Jean Pierre Vieillot in 1816, it contains two or three species, depending on the taxonomy followed. The International Ornithological Congress (IOC) recognises three species: * Thrush-like antpitta (''Myrmothera campanisona'') * Tapajos antpitta (''Myrmothera subcanescens'') * Tepui antpitta (''Myrmothera simplex'') Some other taxonomies, including those followed by the Integrated Taxonomic Information System and Handbook of Birds of the World, consider the Tapajos antpitta to be a subspecies of the thrush-like antpitta. Based on DNA analysis, the genus is considered to be a sister taxon to the genus ''Hylopezus''. The name ''Myrmothera'' is a compound word created from the Greek Greek may refer to: Greece Anything of, from, or related to Greece, a country in Southern Europe: *Greeks, an ethnic group. *Greek language, a branch of the Indo-European language family. ...

Cryptopezus
The speckle-breasted antpitta (''Cryptopezus nattereri'') is a species of bird in the family Grallariidae. It is found in Argentina, Brazil, and Paraguay. It is monotypic in the genus ''Cryptopezus''. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial f ....

Chestnut-crowned Antpitta
The chestnut-crowned antpitta (''Grallaria ruficapilla'') is a species of bird in the family Grallariidae. It is found in Colombia, Ecuador, Peru, and Venezuela. Its natural habitats are subtropical or tropical moist montane forest and heavily degraded former forest, which it has a much greater tolerance for than most antpittas. Usually this bird lives at elevations of . It is mid-sized for an antpitta, averaging long. It has an orange-rufous head and nape. The back is olive brown and the throat is white. The belly is white overlaid with black-brown streaking, mainly on the sides and the flanks. The legs are gray-blue. This combination of field marks renders this species fairly distinctive when seen. Though shy and secretive like all ''Grallaria'' to some extent, this species hops into the open reasonably often, though rarely far from cover. Most often they range into open areas at or soon after dawn. In some areas, this species has become habituated to being fed worms, and in ...

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.

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] |
Vestigial
Vestigiality is the retention, during the process of evolution, of genetically determined structures or attributes that have lost some or all of the ancestral function in a given species. Assessment of the vestigiality must generally rely on comparison with homologous features in related species. The emergence of vestigiality occurs by normal evolutionary processes, typically by loss of function of a feature that is no longer subject to positive selection pressures when it loses its value in a changing environment. The feature may be selected against more urgently when its function becomes definitively harmful, but if the lack of the feature provides no advantage, and its presence provides no disadvantage, the feature may not be phased out by natural selection and persist across species. Examples of vestigial structures (also called degenerate, atrophied, or rudimentary organs) are the loss of functional wings in island-dwelling birds; the human vomeronasal organ; and the hin ...
