Chestnut-headed Tesia
The chestnut-headed tesia (''Cettia castaneocoronata'') is a small insectivorous songbird formerly of the "Old World warbler" family but nowadays placed in the bush warbler family (Cettiidae). Location and habitat It is found in Bangladesh, Bhutan, China, India, Laos, Myanmar, Nepal, Thailand, and Vietnam. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. Taxonomy The chestnut-headed tesia was formally described by the English army officer and zoologist Edward Burton in 1836 under the binomial name ''Sylvia castaneocoronata''. The specific epithet combines the Latin ''castaneus'' meaning "chestnut-coloured" and ''coronatus'' meaning "crowned". Formerly placed in the genus ''Tesia'', a molecular phylogenetic study published in 2011 found that the chestnut-headed tesia was embedded in a clade containing members of the genus ''Cettia''. Three subspecies are recognised: * ''C. c. castaneocoronata'' (Burton, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Burton (zoologist)
Edward Burton FRS FLS (1790 – 11 March 1867) was a British Army surgeon and a zoologist. He was also a magistrate for Kent. Life Little is known of Burton's life. He may have studied at St. George's Hospital, London. The earliest record of his military career is in 1813, when he was attached to the 12th Foot, and was promoted from Hospital-Mate to Assistant-Surgeon. In 1818, he transferred between units. In 1826, he was attached to the 9th Light Dragoons, and was promoted Surgeon to the Forces. In 1837, he retired on half-pay. Burton was stationed at Fort Pitt, Chatham from 1829 to 1837. In 1838, he compiled ''A Catalogue of the Collection of Mammalia and Birds in the Museum of the Army Medical Department at Fort Pitt, Chatham''. He wrote in its Preface, "This task has been undertaken at such broken and uncertain periods as his professional duties left at the disposal of its author". He described several species of bird, for some of which he is the valid binomial aut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of North India
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. Bird ...

Herbert Girton Deignan
Herbert Girton Deignan (December 5, 1906 – March 15, 1968) was an American ornithologist who worked extensively on the birds of Thailand. Deignan was born in New Jersey, the son of Harry Francis and Anna Galena. He grew up in Pennsylvania and schooled in Mercersburg Academy before going to Princeton where he graduated with an Arts Baccalaureate in 1928. He became interested in birds early on and got in contact with Charles H Rogers, curator of the Princeton collections. He became interested in Thailand (Siam) and after graduating he took up a position in the Chiangmai college in northern Siam as a teacher of English. He stayed there from 1928 to 1932, collecting birds in the region that he sent back to Charles Rogers at Princeton. Deignan returned to the United States in 1932. He held a temporary assignment at the US National Museum thanks to Alexander Wetmore. He then took a position at the Library of Congress from 1934 to 1935, and his familiarity with Asian languages helped ... [...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] |
Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cettia
''Cettia'' is a genus of small insectivorous songbirds ("warblers") which make up the core of the newly recognized family Cettiidae. They were formerly placed in the Sylviidae, which at that time was a wastebin taxon for the warbler-like Sylvioidea. The range of this genus extends from Europe to southeast Asia. The genus gets its name from the Cetti's warbler, itself named after the 18th century Italian zoologist Francesco Cetti. The cettiid or typical bush warblers share the lifestyle and related adaptations and apomorphies with ''Bradypterus'', the other genus called bush warblers. However, ''Bradypterus'' is related to the grass warblers of '' Locustella'' and '' Megalurus'' and is more distant from ''Cettia''. Both "bush warbler" genera are smallish birds well adapted to climbing among shrubbery. They are markedly long-tailed birds, at first glance somewhat reminiscent of wrens. These are quite terrestrial birds, which live in densely vegetated habitats such as thick forest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

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.

Tesia
The tesias are a genus, ''Tesia'', of Old World warbler. Though once included in the large family (biology), family Sylviidae, more recent research placed it within a new family, Cettiidae. The four species inhabit undergrowth of montane forest in South Asia, South and Southeast Asia, where they are resident or short-range migrants. They have longish legs and appear tailless, with (seemingly) only 8 rectrices. Their simple songs are fairly loud, and their nests are typically ball-shaped. Their name is derived from ''Tisi'', the Nepali language, Nepalese name for the grey-bellied tesia (''Tesia cyaniventer''). Taxonomy The genus ''Tesia'' was erected in 1837 by the English naturalist Brian Houghton Hodgson. The name is from the Nepalese word ''Tisi'' for the grey-bellied tesia. The type species was designated as the grey-bellied tesia (''Tesia cyaniventer'') by the English zoologist George Robert Gray in 1847. The chestnut-headed tesia was formerly included in the genus.

Binomial Name
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
