Trilling Gnatwren
The trilling gnatwren (''Ramphocaenus melanurus''), formerly long-billed gnatwren, is a very small bird in the gnatcatcher family. It found from southeast Mexico south to Ecuador and Amazonia. Taxonomy The trilling gnatwren was described by the French ornithologist Louis Vieillot in 1819 from a specimen collected in Brazil. He coined the binomial name ''Ramphocaenus melanurus''. The genus name ''Ramphocaenus'' means "unusual beak", from the Ancient Greek ' (, "beak") and ' (, "strange"). The specific epithet combines the Ancient Greek ''melas'' "black" and ''oura'' "tail". A molecular phylogenetic study published in 2018 found that two subspecies of ''Ramphocaenus melanurus'' formed a separate clade. The subspecies were split off to become the chattering gnatwren and the English name of this species was changed from "long-billed gnatwren" to "trilling gnatwren". Thirteen subspecies are recognised: * ''R. m. rufiventris'' ( Bonaparte, 1838) – south Mexico to west Ecuador * '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chattering Gnatwren
The chattering gnatwren (''Ramphocaenus sticturus'') is a species of bird in the family Polioptilidae, the gnatcatchers. It is found in Bolivia, Brazil, and Peru. Taxonomy and systematics The chattering gnatwren was formerly treated as a subspecies of the long-billed gnatwren (since renamed the trilling gnatwren by some taxonomies) (''Ramphocaenus melanurus''). It is now considered a separate species based on the phylogenetic relationships determined in a 2018 molecular study. Two subspecies are recognised: * ''R. s. sticturus'' Hellmayr (1902) * ''R. s. obscurus'' Zimmer, J.T. (1931) Description Little has been written about the chattering gnatwren's appearance other than as a subspecies of trilling gnatwren. The trilling ''sensu lato'' is long and weighs . The nominate chattering gnatwren's upperparts are brown with a blackish tail. It has a buffy stripe over the eye and pale cinnamon cheeks blending to yellowish buff on the sides of the neck. Its undersides are buffy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis Jean Pierre Vieillot
Louis Pierre Vieillot (10 May 1748, Yvetot – 24 August 1830, Sotteville-lès-Rouen) was a French ornithologist. Vieillot is the author of the first scientific descriptions and Linnaean names of a number of birds, including species he collected himself in the West Indies and North America and South American species discovered but not formally named by Félix de Azara and his translator Sonnini de Manoncourt. He was among the first ornithologists to study changes in plumage and one of the first to study live birds. At least 77 of the genera erected by Vieillot are still in use. Biography Vieillot was born in Yvetot. He represented his family's business interests in Saint-Domingue (Haiti) on Hispaniola, but fled to the United States during the Haitian rebellions that followed the French Revolution. On Buffon's advice, he collected material for the ''Histoire naturelle des oiseaux de l'Amérique Septentrionale,'' the first two volumes of which were published in France beginning i ...

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 ...

Bird Genera
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. Bi ...
