Vietnamese Greenfinch
The Vietnamese greenfinch (''Chloris monguilloti'') is a small passerine bird in the family Fringillidae. It is found only in Da Lat, Vietnam. Its natural habitat is subtropical or tropical dry forest. It is threatened by habitat loss. Taxonomy The first formal description of the Vietnamese greenfinch was by the American ornithologist Jean Théodore Delacour in 1926 under the binomial name ''Hypacanthis monguilloti''. In the past the greenfinches were placed in the genus ''Carduelis'' but when molecular phylogenetic studies found that they were not closely related to the other species in ''Carduelis'', they were moved to the resurrected genus '' Chloris''. The genus had been first introduced by the French naturalist Georges Cuvier in 1800. The word ''Chloris'' is from the Ancient Greek ''khlōris'' for the European greenfinch; the specific epithet was chosen to honour Maurice Antoine François Monguillot, the General Secretary of French Indochina. The species is monotypic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean Théodore Delacour
Jean Théodore Delacour (26 September 1890 – 5 November 1985) was a French ornithologist and aviculturist. He later became American. He was renowned for not only discovering but also rearing some of the rarest birds in the world. He established very successful aviaries twice in his life, stocked with birds from around the world, including those that he obtained on expeditions to Southeast Asia, Africa and South America. His first aviary in Villers-Bretonneux was destroyed in World War One. The second one that he established at Clères was destroyed in World War Two. He moved to the United States of America where he worked on avian systematics and was one of the founders of the International Committee for Bird Protection (later BirdLife International). One of the birds he discovered was the imperial pheasant, later identified as a hybrid between the Vietnamese pheasant and the silver pheasant. Life and work Delacour was born in Paris into an aristocratic family and grew up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Birds Described In 1926
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying Laying is the act of making equipment level. It usually involves moving equipment in small motions so that spirit levels are centralised in all planes. Movement is usually done by small worm gears or other fine setting devices for accurate sma ... 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, 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 Fli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Birds Of Vietnam
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...

Maurice Antoine François Monguillot
Maurice Antoine François Monguillot (9 August 1874 – 23 June 1945) was a French colonial administrator in French Indochina and soldier. He served as the acting governor-general of French Indochina three times; from May 1919 to February 1920, April 1925 to November 1925 and November 1927 to August 1928. Biography Monguillot was named a Chevalier of the Légion d’Honneur on 18 January 1911, an Officier (Officer) of the Légion d’Honneur on 23 March 1916, Commandeur (Commander) of the Légion d’Honneur on 18 January 1921. His published notice for Commandeur of the Légion d’Honneur in 1925 notes that he had served as a Resident Superior (First Class) in Indo-China, Resident Superior in Tonkin and was later administrator of the Distilleries of Indochine, president of the Colonial Trust, then president of the nationalized tin mines in Upper Tonkin.

European Greenfinch
The European greenfinch or simply the greenfinch (''Chloris chloris'') is a small passerine bird in the finch family Fringillidae. This bird is widespread throughout Europe, North Africa and Southwest Asia. It is mainly resident, but some northernmost populations migrate further south. The greenfinch has also been introduced into Australia, New Zealand, Uruguay, and Argentina. Taxonomy The greenfinch was described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae'' under the binomial name ''Loxia chloris''. The specific epithet is from ''khloris'', the Ancient Greek name for this bird, from ''khloros'', "green". The finch family, Fringillidae, is divided into two subfamilies, the Carduelinae, containing around 28 genera with 141 species and the Fringillinae containing a single genus, ''Fringilla'', with four species. The finch family are all seed-eaters with stout conical bills. They have similar skull morphologies, nine large primaries, 12 tail fea ...

Georges Cuvier
Jean Léopold Nicolas Frédéric, Baron Cuvier (; 23 August 1769 – 13 May 1832), known as Georges Cuvier, was a French natural history, naturalist and zoology, zoologist, sometimes referred to as the "founding father of paleontology". Cuvier was a major figure in natural sciences research in the early 19th century and was instrumental in establishing the fields of comparative anatomy and paleontology through his work in comparing living animals with fossils. Cuvier's work is considered the foundation of vertebrate paleontology, and he expanded Linnaean taxonomy by grouping classes into phylum, phyla and incorporating both fossils and living species into the classification. Cuvier is also known for establishing extinction as a fact—at the time, extinction was considered by many of Cuvier's contemporaries to be merely controversial speculation. In his ''Essay on the Theory of the Earth'' (1813) Cuvier proposed that now-extinct species had been wiped out by periodic catastrophi ...

Chloris (bird)
The greenfinches are small passerine birds in the genus ''Chloris'' in the subfamily Carduelinae within the Fringillidae. The species have a Eurasian distribution except for the European greenfinch, which also occurs in North Africa. These finches all have large conical bills and yellow patches on the wing feathers. The greenfinches were formerly placed in the genus ''Carduelis''. Molecular phylogenetic studies showed that the greenfinches form a monophyletic group that is not closely related to the species in ''Carduelis'' and instead is sister to a clade containing the desert finch (''Rhodospiza obsoleta'') and the Socotra golden-winged grosbeak (''Rhynchostruthus socotranus''). The greenfinches were therefore moved to the resurrected genus ''Chloris'' which had originally been introduced by the French naturalist Georges Cuvier in 1800 with the European greenfinch as the type species. The name is from Ancient Greek ''khloris'', the European greenfinch, from ''khloros'', "gree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carduelis
The genus ''Carduelis'' is a group of birds in the finch family Fringillidae. The genus ''Carduelis'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760 by tautonomy based on Carl Linnaeus's specific epithet for the European goldfinch ''Fringilla carduelis''. The name ''carduelis'' is the Latin word for the European goldfinch. Many bird species were at one time assigned to the genus, but it became clear from phylogenetic studies of mitochondrial and nuclear DNA sequences that the genus was polyphyletic. The polyphyletic nature of the genus was confirmed by Dario Zuccon and coworkers in a comprehensive study of the finch family published in 2012. The authors suggested splitting the genus into several monophyletic clades, a proposal that was accepted by the International Ornithologists' Union. The siskins and goldfinches from the Americas formed a distinct clade and were moved to the resurrected genus '' Spinus'', the greenfinches were moved to the genus '' C ...

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 ...
