Marsh Grassbird
The marsh grassbird (''Helopsaltes pryeri''), also known as the Japanese swamp warbler, is a species of Old World warbler in the family Locustellidae. It is found in China, Japan, South Korea, Mongolia, and Russia. Its natural habitat is swamps. It is threatened by habitat loss Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease ....

Henry Seebohm
Henry Seebohm (12 July 1832 – 26 November 1895) was an English steel manufacturer, and amateur ornithologist, oologist and traveller. Biography Henry was the oldest son of Benjamin Seebohm (1798–1871) who was a wool merchant at Horton Grange, Bradford. The family had moved to England from Bad Pyrmont in Germany. Henry's mother Estther Wheeler (1798–1864) was a granddaughter of William Tuke. The Seebohms were active in the Society of Friends and Henry schooled within the community in York. He worked initially in a grocery as an assistant but moved to Sheffield where he became a steel manufacturer. He married Maria, daughter of George John Healey, a merchant in Manchester on 19 January 1859. Natural history Henry became interested in natural history at school and continued to spend his spare time studying birds on his journeys. He travelled widely visiting Greece, Scandinavia, Turkey, and South Africa. His expeditions to the Yenisey tundra of Siberia were described in ...

Old World Warbler
The Old World warblers are a large group of birds formerly grouped together in the bird family Sylviidae. They are not closely related to the New World warblers. The family held over 400 species in over 70 genera, and were the source of much taxonomic confusion. Two families were split out initially, the cisticolas into Cisticolidae and the kinglets into Regulidae. In the past 20–30 years they have been the subject of much research and many species are now placed into other families, including the Acrocephalidae, Cettiidae, Phylloscopidae, and Megaluridae. In addition some species have been moved into existing families or have not yet had their placement fully resolved. Only a small number of warblers, in just two genera, are now retained in the family Sylviidae. Characteristics Most Old World warblers are of generally undistinguished appearance, though some species are boldly marked. The sexes are often identical, but may be clearly distinct, notably in the genera '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locustellidae
Locustellidae is a recently recognised family of small insectivorous songbirds (" warblers"), formerly placed in the Old World warbler " wastebin" family. It contains the grasshopper warblers, grassbirds, and the '' Bradypterus'' " bush warblers". These birds occur mainly in Eurasia, Africa, and the Australian region. The family name is sometimes given as Megaluridae, but Locustellidae has priority. The name derives from the type genus name ''Locustella'', which is from Latin and is a diminutive of ''locusta'', "grasshopper". Like the English name grasshopper warbler, this refers to the insect-like song of many species of ''Locustella'', most notably the common grasshopper warbler ''Locustella naevia''. The species are smallish birds with tails that are usually long and pointed; the scientific name of the genus ''Megalurus'' in fact means "the large-tailed one" in plain English. They are less wren-like than the typical shrub-warblers ('' Cettia''), but they are similarl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Habitat
In ecology, habitat refers to the array of resources, 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 Biophysical environment, 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 Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swamp
A swamp is a forested wetland.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater. Freshwater swamps form along large rivers or lakes where they are critically dependent upon rainwater and seasonal flooding to maintain natural water level fluctuations.Hughes, F.M.R. (ed.). 2003. The Flooded Forest: Guidance for policy makers and river managers in Europe on the restoration of floodplain forests. FLOBAR2, Department of Geography, University of Cambridge, Cambridge, UK. 96 p. Saltwater swamps are found along tropical and subtropical coastlines. Some swamps have hammock (ecology), hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerate ...

Habitat Loss
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and Abundance (ecology), species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the Exploitation of natural resources, use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduced species, introduction of invasive species, ecosystem nutrient depletion, water pollution, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helopsaltes
''Helopsaltes'' is a genus of passerine birds in the grassbird family Locustellidae. A comprehensive molecular phylogenetic study of the grassbird family Locustellidae published in 2018 found that the genus ''Locustella'' consisted of two distinct clades. The genus was split and six species were moved to the newly described genus ''Helopsaltes'' with Pallas's grasshopper warbler (''Helopsaltes certhiola'') as the type species. The genus name combines the Ancient Greek ἕλος/''helos'' meaning "marshy ground" and ψάλτης/''psaltis'' "a chanter". As well as the genetic separation, the species of ''Helopsaltes'' also differ markedly from ''Locustella'' in song structure, with varied, 'flowing' warbling songs as opposed to the repetitive and often metronomic insect- (particularly grasshopper)-like songs of ''Locustella'' species. They are very similar to ''Locustella'' species in their cryptic camouflaged plumage, with no differing genus-wide characters; they also show a si ...
