Chestnut-backed Laughingthrush
The chestnut-backed laughingthrush (''Pterorhinus nuchalis'') is a species of bird in the family Leiothrichidae. It is found in Northeast India and northern Myanmar.This species inhabits secondary growth, thickets, tall grasslands with scattered shrubs or dense bushes in stony scrub-covered ravines and hills, from the lowlands up to c.900 m. It is threatened by habitat loss. The chestnut-backed laughingthrush was at one time 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 ''Pterorhinus'' is a genus of passerine birds in the laughingthrush family Leiothrichidae.

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. His grandfather, Sir Henry Edmund Austen (1785– ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Myanmar
Myanmar, ; UK pronunciations: US pronunciations incl. . Note: Wikipedia's IPA conventions require indicating /r/ even in British English although only some British English speakers pronounce r at the end of syllables. As John Wells explains, the English spellings of both Myanmar and Burma assume a non-rhotic variety of English, in which the letter r before a consonant or finally serves merely to indicate a long vowel: �mjænmɑː, ˈbɜːmə So the pronunciation of the last syllable of Myanmar as ɑːror of Burma as ɜːrməby some speakers in the UK and most speakers in North America is in fact a spelling pronunciation based on a misunderstanding of non-rhotic spelling conventions. The final ''r'' in ''Myanmar'' was not intended for pronunciation and is there to ensure that the final a is pronounced with the broad ''ah'' () in "father". If the Burmese name my, မြန်မာ, label=none were spelled "Myanma" in English, this would be pronounced at the end by al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, ... [...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 ...
