Yellow-throated Laughingthrush
The yellow-throated laughingthrush (''Pterorhinus galbanus'') is a species of bird in the family Leiothrichidae. It is found in grassy areas with bushes and trees, scrub and forest in the Patkai mountain range. Until recently, it included the blue-crowned laughingthrush as a subspecies, but unlike that species the crown of the yellow-throated laughingthrush is pale grey (not bluish). The yellow-throated laughingthrush was formerly placed in the genus ''Garrulax'' but following the publication of a comprehensive molecular phylogenetic study in 2018, it was moved to the resurrected genus ''Pterorhinus''.

John Gould
John Gould (; 14 September 1804 – 3 February 1881) was an English ornithologist. He published a number of monographs on birds, illustrated by plates produced by his wife, Elizabeth Gould, and several other artists, including Edward Lear, Henry Constantine Richter, Joseph Wolf and William Matthew Hart. He has been considered the father of bird study in Australia and the Gould League in Australia is named after him. His identification of the birds now nicknamed "Darwin's finches" played a role in the inception of Darwin's theory of evolution by natural selection. Gould's work is referenced in Charles Darwin's book, ''On the Origin of Species''. Early life Gould was born in Lyme Regis, the first son of a gardener. Both father and son probably had little education. After working on Dowager Lady Poulett's glass house, his father obtained a position on an estate near Guildford, Surrey, and then in 1818, Gould Snr became foreman in the Royal Gardens of Windsor.

William Matthew Hart
William Matthew Hart (1830-1908) was an Irish-born English bird illustrator and lithographer who worked for John Gould. Hart started medical training, but was unable to complete his studies for financial reasons. He began working for Gould in 1851, beginning an association that was to last thirty years. Early during this period he made the patterns for the lithography, lithographic plates for Gould's work on hummingbirds, as well as working on ''The Birds of Great Britain'' with Henry Constantine Richter. By 1870 Hart had become Gould's chief artist and lithographer. After Gould's death in 1881, Hart was employed by Richard Bowdler Sharpe of the British Museum to complete Gould's work on the birds of New Guinea and to produce illustrations for Sharpe's monograph on the birds-of-paradise.

Henry Haversham Godwin-Austen
Lieutenant-Colonel Henry Haversham Godwin-Austen FRS FZS FRGS MBOU (6 July 1834 – 2 December 1923), known until 1854 as Henry Haversham Austen, was an English topographer, surveyor, naturalist and geologist. He explored the mountains in the Himalayas and surveyed the glaciers at the base of K2, also known as Mount Godwin-Austen. Geographer Kenneth Mason called Godwin-Austen "probably the greatest mountaineer of his day". He also remains the most important investigator of the terrestrial molluscs of the Indian subcontinent. Early life The eldest son of the geologist Robert Austen, who in 1854 added Godwin to his surname by royal licence, Henry Haversham Austen was probably born at Ogwell House, near Newton Abbot, Devon, where his father had recently taken up residence. His father's family, landowners in Cheshire and Surrey since the 12th century, was a family of merchant venturers, soldiers, scholars, and collectors.

Bird
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 swimm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leiothrichidae
The laughingthrushes are a family, Leiothrichidae, of Old World passerine birds. They are diverse in size and coloration. These are birds of tropical areas, with the greatest variety in Southeast Asia and the Indian subcontinent. The entire family used to be included in the Old World babbler family Timaliidae. Characteristics They are small to medium-sized birds. They have strong legs, and many are quite terrestrial. They typically have generalised bills, similar to those of a thrush. Most have predominantly brown plumage, with minimal difference between the sexes, but many more brightly coloured species also exist. This group is not strongly migratory, and most species have short rounded wings, and a weak flight. They live in lightly wooded or scrubland environments, ranging from swamp to near-desert. They are primarily insectivorous, although many will also take berries, and the larger species will even eat small lizards and other vertebrates. Taxonomy The family Leiothric ...

Patkai
The Pat-kai (Pron:pʌtˌkaɪ) or Patkai Bum (Burmese: ''Kumon Taungdan'') are a series of mountains in the Indo-Myanmar border falling in the north-eastern Indian states of Arunachal Pradesh, Nagaland and Upper Burma region of Myanmar. They were created by the same tectonic processes that created the Himalayas in the Mesozoic. In Tai-Ahom language, Pat means ''to cut'' and Kai means ''chicken''. Geography The Patkai range mountains are not as rugged as the Himalayas and the peaks are much lower. Features of the range include conical peaks, steep slopes and deep valleys. Three mountain ranges come under the Patkai. The Patkai-Bum, the Garo-Khasi-Jaintia hills and the Lushai Hills. The highest point of this range is Phawngpui Tlang, which is also known as 'Blue Mountain'. The Garo-Khasi range is in the Indian state of Meghalaya. Mawsynram and Cherrapunji, on the windward side of these mountains are the world's wettest places, having the highest annual rainfall. The climat ...

Blue-crowned Laughingthrush
The blue-crowned laughingthrush or Courtois's laughingbird (''Pterorhinus courtoisi'') is a species of bird in the family Leiothrichidae. It is now found only in Jiangxi, China. Until recently, this critically endangered species was generally treated as a subspecies of the yellow-throated laughingthrush, but that species has a pale grey (not bluish) crown. The blue-crowned laughingthrush was formerly placed in the genus ''Garrulax'' but following the publication of a comprehensive molecular phylogenetic study in 2018, it was moved to the resurrected genus ''Pterorhinus''. The specific name was chosen to honour the French missionary to China Frédéric Courtois (1860-1928). The nominate subspecies was only rediscovered in 2000, in Wuyuan County, Jiangxi, but remains very rare with a total wild population of approximately 200 individuals. The subspecies ''G. courtoisi simaoensis'' has not been encountered in the wild since the type specimens were collected in Simao, Yunnan in ...

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 w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garrulax
''Garrulax'' is a genus of passerine birds in the laughingthrush family Leiothrichidae. Taxonomy The genus ''Garrulax'' was erected by the French naturalist René Lesson in 1831. The type species was designated in 1961 as the rufous-fronted laughingthrush (''Garrulax rufifrons''). The genus previously included more species. Following the publication of a comprehensive molecular phylogenetic study in 2018, ''Garrulax '' was split up and species were moved to the resurrected genera ''Ianthocincla'' and '' Pterorhinus''. ''Garrulax'' species are heavily traded as songbirds. A survey of eight bird markets in Indonesia, carried out in 2014–2015, found 615 laughingthrushes of nine species openly for sale. Much of the trade in these species in Indonesia is illegal and is pushing a number of these species towards extinction. The Sumatran Laughingthrush, for example, is in serious decline due to ongoing and uncontrolled illegal trade in bird markets on the islands of Java and Su ...

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. History The theoretical ...

Pterorhinus
''Pterorhinus'' is a genus of passerine birds in the laughingthrush family Leiothrichidae. Taxonomy The genus was erected by the English zoologist Robert Swinhoe in 1868 with the plain laughingthrush (''Pterorhinus davidi'') as the type species. The name of the genus combines the Ancient Greek ''pteron'' meaning "feather" with ''rhinos'' meaning "nostrils". These species were at one time placed in ''Garrulax'' but following the publication of a molecular phylogenetic study in 2018, ''Garrulax'' was split up and some of the species were moved to the resurrected genus ''Pterorhinus''. At the same time, the four species previously placed in ''Babax'' were moved here. Species The genus contains 23 species: * Rufous-necked laughingthrush, ''Pterorhinus ruficollis'' * Chestnut-backed laughingthrush, ''Pterorhinus nuchalis'' * Black-throated laughingthrush, ''Pterorhinus chinensis'' * Chestnut-capped laughingthrush, ''Pterorhinus mitratus'' * Chestnut-hooded laughingthrush, ''Pterorhin ...
