Bernieridae
The tetrakas, also known as the Malagasy warblers, are a recently validated family of songbirds. They were formally named Bernieridae in 2010. The family currently consists of eleven species (in eight genera) of small forest birds. These birds are all endemic to Madagascar. In 1934, the monophyly of this group was proposed by Finn Salomonsen but the traditional assignments of these birds were maintained, mistaken by their convergent evolution and the lack of dedicated research. The families to which the Malagasy warblers were formerly assigned—Pycnonotidae (bulbuls) and even more so Timaliidae (Old World babblers) and the Old World warbler—were used as " wastebin taxa", uniting unrelated lineages that were somewhat similar ecologically and morphologically. It was not until the analysis of mtDNA cytochrome ''b'' and 16S rRNA as well as nDNA RAG-1 and RAG-2 exon sequence data, that the long-proposed grouping was accepted. Taxonomy and systematics The family contains 11 sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Appert's Tetraka
Appert's tetraka formerly known as Appert's greenbul (''Xanthomixis apperti'') is a small passerine bird endemism, endemic to the south-west of Madagascar. The species was only described in 1972, and has been the subject of considerable taxonomic confusion. It was initially placed in the greenbul genus ''Phyllastrephus'', and later with the Old World warblers in the genus ''Bernieria''. Recent research indicates it is part of an endemic Malagasy radiation currently known as the Malagasy warblers (Cibois ''et al.'' 2001). The Appert's tetraka is around long with a pink bill and grey legs. The plumage of the sexes is similar; the back, tail and wings are green (the wings being a darker shade), the head grey and the throat white. The flanks and belly are washed orange and the undersides are white. The species is highly terrestrial, feeding in undisturbed forest in shrubs near the ground and on the ground. Family groups of up to 8 birds, sometimes in association with other species, f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Richard Bowdler Sharpe
Richard Bowdler Sharpe (22 November 1847 – 25 December 1909) was an English people, English zoologist and ornithology, ornithologist who worked as curator of the bird collection at the British Museum of natural history. In the course of his career he published several monographs on bird groups and produced a multi-volume catalogue of the specimens in the collection of the museum. He described many new species of bird and also has had species named in his honour by other ornithologists including Sharpe's longclaw (''Macronyx sharpei'') and Sharpe's starling (''Pholia sharpii''). Biography Richard was born in London, the first son of Thomas Bowdler Sharpe. His grandfather, Reverend Lancelot Sharpe was Rector of All Hallows Staining. His father was a publisher on Skinner Street and was best known for being the publisher of ''Sharpe's London Magazine'', an illustrated periodical (weekly but monthly from 1847). His care from the age of six was under an aunt, Magdalen Wallace, widow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Bird
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings 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 Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madagascar
Madagascar, officially the Republic of Madagascar, is an island country that includes the island of Madagascar and numerous smaller peripheral islands. Lying off the southeastern coast of Africa, it is the world's List of islands by area, fourth largest island, the List of island countries, second-largest island country, and the List of countries and dependencies by area, 46th largest country overall. Its capital and List of cities in Madagascar, largest city is Antananarivo. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from Africa during the Early Jurassic period, around 180 million years ago, and separated from the Indian subcontinent approximately 90 million years ago. This isolation allowed native plants and animals to evolve in relative seclusion; as a result, Madagascar is a biodiversity hotspot and one of the world's 17 megadiverse countries, with over 90% of its wildlife of Madagascar, wildlife being endemic. The island has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
