Swamp Grass Babbler
The swamp grass babbler or swamp prinia (''Laticilla cinerascens'') is a small bird of the Indian subcontinent. Some authorities consider it a subspecies of the rufous-vented grass babbler. Range, habitat, and status The swamp grass babbler occurs in the plains of the Brahmaputra and the Cachar district in the state of Assam, India, and in nearby parts of northern Bangladesh. It lives in a variety of habitats with tall grasses or brushes, notably plains of sarkhan (''Saccharum'') with or without scattered acacias and tamarisks, but also plains of elephant grass and ekra grass, and even deserts with scattered patches of tall grass, and reedbeds. It prefers areas near large rivers or swamps.. Description Swamp grass babblers average long (big for a prinia). Adults are olive-grey above, slightly warmer on the back of the neck and upper back, but less distinctly collared than the rufous-vented grass babbler. Bold dark streaking starts at the forehead and fades on the back. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur Hay, 9th Marquess Of Tweeddale
Colonel Arthur Hay, 9th Marquess of Tweeddale, (9 November 1824 – 29 December 1878), known before 1862 as Lord Arthur Hay and between 1862 and 1876 as Viscount Walden, was a Scottish soldier and ornithologist. Life Lord Arthur Hay was born at Yester House near Gifford, East Lothian, the son of General Sir George Hay, 8th Marquess of Tweeddale and his wife, Lady Susan Montague. He was sent to university in both Leipzig and Geneva. Training in the military he received a commission in the British Army in 1841. He rose to be a Colonel in the Grenadier Guards. He served as a soldier in India and the Crimea. He succeeded his father in the Marquessate in 1876. Hay purchased a lieutenancy in the Grenadier Guards in 1841. He purchased a captaincy in 1846 and was promoted lieutenant-colonel without purchase in 1854 and Colonel in 1860. In 1866 he transferred to the 17th Lancers. He was president of the Zoological Society of London from 16 January 1868. He had a private collect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ekra
''Tripidium ravennae'', synonym ''Saccharum ravennae'' (and many others), with the common names ravennagrass and elephant grass, is a species of grass in the genus ''Tripidium''. It is native to southern Europe, western Asia and South Asia and is known in North America as an introduced species, where it is sometimes an invasive and troublesome noxious weed. Uses Ravennagrass is a large, aggressive grass that has been sold in nurseries for use as an ornamental grass in gardens, and for stabilizing soil to prevent erosion. It is sold under the name "hardy pampas grass." Invasive species ''Tripidium ravennae'' is now established as an invasive species in several parts of North America, including Glen Canyon National Recreation Area in Utah, the Rio Grande Valley State Park in Albuquerque, New Mexico, and parts of California. It grows in the moist soil of riparian habitats including marshes and riverbanks. This perennial grass grows in large, dense clumps from a network of rhizome ...

Birds Of Northeast India
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. Bird ...

Laticilla
''Laticilla'' is a genus of small passerine birds in the family Pellorneidae. Members of the genus are found in Pakistan, Nepal, India and Bangladesh. A molecular phylogenetic study of the Cisticolidae published in 2013 found that the rufous-vented grass babbler did not lie within the clade containing the other prinias but instead belonged to the Pellorneidae. To create monophyletic genera, the rufous-vented prinia and the closely related swamp grass babbler were placed in the reintroduced genus ''Laticilla'' in the Pellorneidae. The genus ''Laticilla'' had been erected by the English zoologist Edward Blyth in 1845 with the rufous-vented prinia as the type species In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen .... The genus replaced ''Eurycercus'' that Blyth had introduced in 184 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Clements Checklist Of Birds Of The World
''The Clements Checklist of Birds of the World'' is a book by Jim Clements which presents a list of the bird species of the world. The most recent printed version is the sixth edition (2007), but has been updated yearly, the last version in 2022, and is published by Cornell University Press. Previous editions were published by the author's own imprint, Ibis Publishing. The Cornell Lab of Ornithology has provided annual updates since then, usually in August, and the most recent version is available online in several formats. These updates reflect the ongoing changes to bird taxonomy based on published research. ''Clements'' is the official list used by the American Birding Association for birds globally. eBird eBird is an online database of bird observations providing scientists, researchers and amateur naturalists with real-time data about bird distribution and abundance. Originally restricted to sightings from the Western Hemisphere, the project ... also uses the ''Clem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handbook Of The Birds Of The World
The ''Handbook of the Birds of the World'' (HBW) is a multi-volume series produced by the Spanish publishing house Lynx Edicions in partnership with BirdLife International. It is the first handbook to cover every known living species of bird. The series was edited by Josep del Hoyo, Andrew Elliott, Jordi Sargatal and David A. Christie. All 16 volumes have been published. For the first time an animal class will have all the species illustrated and treated in detail in a single work. This has not been done before for any other group in the animal kingdom. Material in each volume is grouped first by family, with an introductory article on each family; this is followed by individual species accounts (taxonomy, subspecies and distribution, descriptive notes, habitat, food and feeding, breeding, movements, status and conservation, bibliography). In addition, all volumes except the first and second contain an essay on a particular ornithological theme. More than 200 renowned speci ...

Lumpers And Splitters
Lumpers and splitters are opposing factions in any discipline that has to place individual examples into rigorously defined categories. The lumper–splitter problem occurs when there is the desire to create classifications and assign examples to them, for example schools of literature, biological taxa and so on. A "lumper" is a person who assigns examples broadly, assuming that differences are not as important as signature similarities. A "splitter" is one who makes precise definitions, and creates new categories to classify samples that differ in key ways. Origin of the terms The earliest known use of these terms was by Charles Darwin, in a letter to Joseph Dalton Hooker in 1857: ''It is good to have hair-splitters & lumpers''. They were introduced more widely by George G. Simpson in his 1945 work ''The Principles of Classification and a Classification of Mammals''. As he put it: A later use can be found in the title of a 1969 paper "On lumpers and splitters ..." by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dunnock
The dunnock (''Prunella modularis'') is a small passerine, or perching bird, found throughout temperate Europe and into Asian Russia. Dunnocks have also been successfully introduced into New Zealand. It is by far the most widespread member of the accentor family; most other accentors are limited to mountain habitats. Other common names of the dunnock include: hedge accentor, hedge sparrow or hedge warbler. Taxonomy The dunnock was described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae''. He coined the binomial name of ''Motacilla modularis''. The specific epithet is from the Latin ''modularis'' "modulating" or "singing". This species is now placed in the genus '' Prunella'' that was introduced by the French ornithologist Louis Vieillot in 1816. The name "dunnock" comes from the English ''dun'' (dingy brown, dark-coloured) and the diminutive ''ock'', and "accentor" is from post-classical Latin and means a person who sings with a ...

Flight Feather
Flight feathers (''Pennae volatus'') are the long, stiff, asymmetrically shaped, but symmetrically paired pennaceous feathers on the wings or tail of a bird; those on the wings are called remiges (), singular remex (), while those on the tail are called rectrices (), singular rectrix (). The primary function of the flight feathers is to aid in the generation of both thrust and lift (force), lift, thereby enabling bird flight, flight. The flight feathers of some birds have evolved to perform additional functions, generally associated with territorial displays, courtship rituals or feeding methods. In some species, these feathers have developed into long showy plumes used in visual courtship displays, while in others they create a sound during display flights. Tiny serrations on the leading edge of their remiges help owls to fly silently (and therefore hunt more successfully), while the extra-stiff rectrices of woodpeckers help them to brace against tree trunks as they hammer on ...

Reed Bed
A reedbed or reed bed is a natural habitat found in floodplains, waterlogged depressions and estuaries. Reedbeds are part of a succession from young reeds colonising open water or wet ground through a gradation of increasingly dry ground. As reedbeds age, they build up a considerable litter layer that eventually rises above the water level and that ultimately provides opportunities in the form of new areas for larger terrestrial plants such as shrubs and trees to colonise. Artificial reedbeds are used to remove pollutants from greywater, and are also called constructed wetlands. Types Reedbeds vary in the species that they can support, depending upon water levels within the wetland system, climate, seasonal variations, and the nutrient status and salinity of the water. ''Reed swamps'' have 20 cm or more of surface water during the summer and often have high invertebrate and bird species use. ''Reed fens'' have water levels at or below the surface during the summer and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
