Nicobar Jungle Flycatcher
The Nicobar jungle flycatcher (''Cyornis nicobaricus'') is a species of bird in the Old World flycatcher family Muscicapidae. It is endemic to the Nicobar Islands where its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical mangrove forests. It was at one time considered as a subspecies of the brown-chested jungle flycatcher. This species was previously placed in the genus ''Rhinomyias'' but was moved to ''Cyornis'' based on the results of a 2010 molecular phylogenetic study.

Charles Wallace Richmond
Charles Wallace Richmond (December 31, 1868 – May 19, 1932) was an American ornithologist. He is best remembered for a compilation of the Latin names of birds that is called the Richmond Index. Life and work He was born in Kenosha, Wisconsin and was the eldest son of Edward Leslie and Josephine Ellen Richmond. His mother died when he was 12. His father who was a railway mail clerk moved to Washington, D.C. and joined the Government Printing House there. His father remarried and he had the additional duty of taking care of younger stepbrothers. During his early life he earned extra income for the family by leaving school and working as a page in the House of Representatives. At the age of 15 he got a position as a messenger in the Geological Survey. In 1897 he graduated after studied medicine in Georgetown University and in the next year he married Louise H. Seville. While still at Wisconsin he had collected the eggs of a Kingbird and when he moved to Washington, in 1881. He visi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muscicapidae
The Old World flycatchers are a large family, the Muscicapidae, of small passerine birds restricted to the Old World (Europe, Africa and Asia), with the exception of several vagrants and two species, Bluethroat (''Luscinia svecica)'' and Northern Wheatear (''Oenanthe oenanthe''), found also in North America. These are mainly small arboreal insectivores, many of which, as the name implies, take their prey on the wing. The family includes 344 species and is divided into 51 genera. Taxonomy The name Muscicapa for the family was introduced by the Scottish naturalist John Fleming in 1822. The word had earlier been used for the genus ''Muscicapa'' by the French zoologist Mathurin Jacques Brisson in 1760. Muscicapa comes from the Latin ''musca'' meaning a fly and '' capere'' to catch. In 1910 the German ornithologist Ernst Hartert found it impossible to define boundaries between the three families Muscicapidae, Sylviidae (Old World warblers) and Turdidae (thrushes). He therefore treat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicobar Islands
The Nicobar Islands are an archipelagic island chain in the eastern Indian Ocean. They are located in Southeast Asia, northwest of Aceh on Sumatra, and separated from Thailand to the east by the Andaman Sea. Located southeast of the Indian subcontinent, across the Bay of Bengal, they are part of India, as the Nicobar district within the union territory of the Andaman and Nicobar Islands. UNESCO has declared the Great Nicobar Island as one of the World Network of Biosphere Reserves. The International Coordinating Council of UNESCO’s Man and the Biosphere Programme (MAB), added the following new sites to the World Network of Biosphere Reserves (WNBR) http://www.unesco.org/new/en/media-services/multimedia/photos/mab-2013/india/.

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] |
Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. 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 ...

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 Of The Nicobar Islands
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. Birds ...

Endemic Fauna Of The Nicobar Islands
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] |
