Gallinule
Moorhens—sometimes called marsh hens—are medium-sized water birds that are members of the rail family (Rallidae). Most species are placed in the genus ''Gallinula'', Latin for "little hen". They are close relatives of coots. They are often referred to as (black) gallinules. Recently, one of the species of ''Gallinula'' was found to have enough differences to form a new genus '' Paragallinula'' with the only species being the lesser moorhen (''Paragallinula angulata''). Two species from the Australian region, sometimes separated in , are called "native hens" (also native-hen or nativehen). The native hens differ visually by shorter, thicker and stubbier toes and bills, and longer tails that lack the white signal pattern of typical moorhens.Boles (2005) Description These rails are mostly brown and black with some white markings in plumage colour. Unlike many of the rails, they are usually easy to see because they feed in open water margins rather than hidden in reedbed ...

Rail (bird)
The rails, or Rallidae, are a large cosmopolitan family of small- to medium-sized, ground-living birds. The family exhibits considerable diversity and includes the crakes, coots, and gallinules. Many species are associated with wetlands, although the family is found in every terrestrial habitat except dry deserts, polar regions, and alpine areas above the snow line. Members of the Rallidae occur on every continent except Antarctica. Numerous island species are known. The most common rail habitats are marshland and dense forest. They are especially fond of dense vegetation.Horsfall & Robinson (2003): pp. 206–207 Name "Rail" is the anglicized respelling of the French ''râle'', from Old French ''rasle''. It is named from its harsh cry, in Vulgar Latin *''rascula'', from Latin ''rādere'' ("to scrape"). Morphology The rails are a family of small to medium-sized, ground-living birds. They vary in length from and in weight from . Some species have long necks and in many ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Moorhen
The common moorhen (''Gallinula chloropus''), also known as the waterhen or swamp chicken, is a bird species in the rail (bird), rail family (Rallidae). It is distributed across many parts of the Old World. The common moorhen lives around well-vegetated marshes, ponds, canals and other wetlands. The species is not found in the polar regions or many tropical rainforests. Elsewhere it is likely the most common rail species, except for the Eurasian coot in some regions. The closely related common gallinule of the New World has been recognized as a separate species by most authorities, starting with the American Ornithologists' Union and the International Ornithological Committee in 2011. Name The name ''mor-hen'' has been recorded in English language, English since the 13th century. The word ''moor'' here is an old sense meaning ''marsh''; the species is not usually found in moorland. An older name, common waterhen, is more descriptive of the bird's habitat. A "watercock" is not a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dusky Moorhen
The dusky moorhen (''Gallinula tenebrosa'') is a bird species in the rail family and is one of the eight extant species in the moorhen genus. It occurs in India, Australia, New Guinea, Borneo and Indonesia. It is often confused with the purple swamphen and the Eurasian coot due to similar appearance and overlapping distributions. They often live alongside birds in the same genus, such as the Tasmanian nativehen and the common moorhen. Taxonomy John Gould described the dusky moorhen in 1846 from a skin collected along the Murray River in South Australia. Its species name is derived from the Latin ''tenebrosa'' "dark". Charles Lucien Bonaparte described ''Gallinula haematopus'' in 1856, but this is now a ''nomen nudum''. Gregory Mathews described two subspecies that have been synonymized—''magnirostris'' from Western Australia and ''subfrontata'' from New South Wales. Three subspecies are recognised: subspecies ''frontata'' from southeastern Borneo, the Sunda Islands, Timor an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gough Moorhen
The Gough moorhen (''Gallinula comeri'') is a medium-sized, almost flightless bird that is similar to the common moorhen (''Gallinula chloropus''), but is smaller, stockier, and has shorter wings. The bird has a distinctive yellow-tipped red bill and red frontal shield. Its first account was written in 1888 by the polar explorer George Comer, whom the specific name ''comeri'' commemorates. This bird is found only on two remote islands in the South Atlantic. The Gough moorhen was originally endemic to Gough Island, but in 1956 was introduced to Tristan da Cunha, an island in the same archipelago which was formerly home of the now extinct Tristan moorhen (''Galinula nesiotis''). On the basis of DNA sequencing of both recently collected and historical material from both of the archipelago's moorhen species, Groenenberg ''et al'' (2008) concluded that the genetic distances between ''G. nesiotis'' and ''G. comeri'' are of at least the same size as those found between subspeci ...

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 expanded to include New Zealand in 2008, and again expanded to cover the whole world in June 2010. eBird has been described as an ambitious example of enlisting amateurs to gather data on biodiversity for use in science. eBird is an example of crowdsourcing, and has been hailed as an example of democratizing science, treating citizens as scientists, allowing the public to access and use their own data and the collective data generated by others. History and purpose Launched in 2002 by the Cornell Lab of Ornithology at Cornell University and the National Audubon Society, eBird gathers basic data on bird abundance and distribution at a variety of spatial and temporal scales. It was mainly inspired by the ÉPOQ database, created by Jac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tasmania Parks And Wildlife Service
Tasmania Parks and Wildlife Service is the government body responsible for protected areas of Tasmania on public land, such as national parks, historic sites and regional reserves. Historically it has also had responsibility for managing wildlife, including game. History The National Parks and Wildlife Service was set up on 1 November 1971 after controversy surrounding the proposal to flood Lake Pedder and the unsuccessful attempts to prevent the project going ahead. A Select Committee formed from the interested parties recommended the establishment of a professional park service to properly manage the natural environment in Tasmania. The service initially had a staff of 59. The '' National Parks and Wildlife Act 1970'' had made provisions for the conservation of fauna and flora and the establishment and management of national parks. Mount William, Maria Island and Narawntapu National Parks were set up and Macquarie Island designated as a nature reserve. The creation of an A ...

Late Oligocene
The Chattian is, in the geologic timescale, the younger of two ages or upper of two stages of the Oligocene Epoch/ Series. It spans the time between . The Chattian is preceded by the Rupelian and is followed by the Aquitanian (the lowest stage of the Miocene). Stratigraphic definition The Chattian was introduced by Austrian palaeontologist Theodor Fuchs in 1894. Fuchs named the stage after the Chatti, a Germanic tribe.Berry, Edward W"The Mayence Basin, a Chapter of Geologic History" ''The Scientific Monthly'', Vol. 16, No. 2, February 1923. pp. 114. Retrieved March 18, 2020. The original type locality was near the German city of Kassel. The base of the Chattian is at the extinction of the foram genus ''Chiloguembelina'' (which is also the base of foram biozone P21b). An official GSSP for the Chattian Stage was ratified in October of 2016. The top of the Chattian Stage (which is the base of the Aquitanian Stage, Miocene Series and Neogene System) is at the first appeara ...

Feather
Feathers are epidermal growths that form a distinctive outer covering, or plumage, on both avian (bird) and some non-avian dinosaurs and other archosaurs. They are the most complex integumentary structures found in vertebrates and a premier example of a complex evolutionary novelty. They are among the characteristics that distinguish the extant birds from other living groups. Although feathers cover most of the bird's body, they arise only from certain well-defined tracts on the skin. They aid in flight, thermal insulation, and waterproofing. In addition, coloration helps in communication and protection. Plumology (or plumage science) is the name for the science that is associated with the study of feathers. Feathers have a number of utilitarian, cultural, and religious uses. Feathers are both soft and excellent at trapping heat; thus, they are sometimes used in high-class bedding, especially pillows, blankets, and mattresses. They are also used as filling for winter ...
