Manchurian Bush Warbler
The Manchurian bush warbler (''Horornis canturians''), also known as Korean bush warbler, is a bird in the family Cettiidae. The species was first described by Robert Swinhoe Robert Swinhoe FRS (1 September 1836 – 28 October 1877) was an English diplomat and naturalist who worked as a Consul in Formosa. He catalogued many Southeast Asian birds, and several, such as Swinhoe's pheasant, are named after him. Bio ... in 1860. It is found in northeastern China. The estimated distribution size is reported to be a large range – approximately 1,610,000 km2. Although the global population has not been measured, the population trend appears to be stable. Because of this, the Manchurian bush warbler is evaluated as a least concern species. It is most active in the morning. It is often confused for '' the Japanese bush warbler.'' Its vocalizations have been described as "explosive" and "trilling." References Manchurian bush warbler Birds of Manchuria Manchur ...

Robert Swinhoe
Robert Swinhoe FRS (1 September 1836 – 28 October 1877) was an English diplomat and naturalist who worked as a Consul in Formosa. He catalogued many Southeast Asian birds, and several, such as Swinhoe's pheasant, are named after him. Biography Swinhoe was born in Calcutta where his father, who came from a Northumberland family, was a lawyer. There is no clear record of the date of his arrival in England, but it is known he attended the University of London, and in 1854 joined the China consular corps. He was stationed to the remote port of Amoy, some 300 miles to the northeast of Hong Kong, in 1855. While at this port he not only mastered the Chinese language (both official Mandarin and the local Amoy dialect), but also initiated a detailed and authoritative understanding of the ornithology of eastern China. In March, 1856, Swinhoe made an "adventurous" visit to the camphor districts of northwestern Formosa on board a lorcha, a hybrid vessel utilizing a European hull an ...

Cettiidae
Cettiidae is a newly validated family of small insectivorous songbirds ("warblers"), formerly placed in the Old World warbler "wastebin" assemblage. It contains the typical bush warblers (''Cettia'') and their relatives. As a common name, cettiid warblers is usually used. Some taxonomic authorities include this entire family, as D. Winkler et al. in an enlarged family Scotocercidae. Its members occur mainly in Asia ranging into Oceania and Europe. The pseudo-tailorbirds, tesias and stubtails, as well as ''Tickellia'' and ''Abroscopus'' warblers are mostly found in the forests of south and southeastern Asia, with one species reaching as far north as Japan and Siberia. Only one species, Neumann's warbler (''Hemitesia neumanni''), occurs in Africa. The genus ''Cettia'' has the widest distribution of the family, reaching from Western Europe across Asia to the Pacific islands of Fiji and Palau. Most of the species in the family are sedentary, but the Asian stubtail is wholly migra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northeast China
Northeast China or Northeastern China () is a geographical region of China, which is often referred to as "Manchuria" or "Inner Manchuria" by surrounding countries and the West. It usually corresponds specifically to the three provinces east of the Greater Khingan Range, namely Liaoning, Jilin, and Heilongjiang, but historically is meant to also encompass the four easternmost prefectures of Inner Mongolia west of the Greater Khingan. The heartland of the region is the Northeast China Plain, the largest plain in China, with an area over . It is separated from Russian Far East to the north by the Amur, Argun, and Ussuri rivers; from Korea to the south by the Yalu and Tumen Rivers; and from Inner Mongolia to the west by the Greater Khingan and parts of the Xiliao River. Due to the shrinking of its once-powerful industrial sector and decline of its economic growth and population, the region is often referred to as China's Rust Belt. As a result, a campaign named Northeast Area Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Population Trend
Population growth is the increase in the number of people in a population or dispersed group. Actual global human population growth amounts to around 83 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7.9 billion in 2020. The UN projected population to keep growing, and estimates have put the total population at 8.6 billion by mid-2030, 9.8 billion by mid-2050 and 11.2 billion by 2100. However, some academics outside the UN have increasingly developed human population models that account for additional downward pressures on population growth; in such a scenario population would peak before 2100. World human population has been growing since the end of the Black Death, around the year 1350. A mix of technological advancement that improved agricultural productivity and sanitation and medical advancement that reduced mortality increased population growth. In some geographies, this has slowed through the process called the demographic tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least Concern Species
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

Japanese Bush Warbler
The Japanese bush warbler (''Horornis diphone''), known in Japanese as ''uguisu'' (鶯), is an Asian passerine bird more often heard than seen. Its distinctive breeding song can be heard throughout much of Japan from the start of spring. Description The Japanese bush warbler is olive brown above and tending toward dusky colors below. It has pale eyebrows. It has a beak that curves up making it look like it is smiling. The bird is typically in length. Distribution and habitat The Japanese bush warbler is a common year-round resident throughout Japan (except Hokkaidō) and the northern Philippines. In summer the Japanese bush warbler can also be found in Hokkaidō, Manchuria, Korea, and central China. In winter, the bush-warbler can also be found in southern China and Taiwan. It was introduced to Oahu between 1929–1941 and has since spread throughout the main Hawaiian Islands. In summer it ranges from low hills to high mountains, preferring bamboo thickets and black pine tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horornis
''Horornis'' 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 occurs from southeast Asia throughout the western Pacific. The most recently described species is the Bougainville bush warbler (''Horornis haddeni'') from Bougainville Island. These 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 thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Manchuria
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 ...

Taxonomy Articles Created By Polbot
Taxonomy is the practice and science of categorization or classification (general theory), classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a Taxonomy for search engines, search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchy, hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic uni ...
