Moorhen
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 color. Unlike many of the rails, they are usually easy to see because they feed in open water margins rather than hidden in reed ...

Common Moorhen
The common moorhen (''Gallinula chloropus''), also known as the waterhen, is a bird species in the Rail (bird), rail family (Rallidae). It is distributed across many parts of the Old World, across Africa, Europe, and Asia. It lives around well-vegetated marshes, ponds, canals and other wetlands. The species is not found in the polar regions or many tropical rainforests; generally it is one of the commonest Old World rail species, together with the Eurasian coot in some regions. Taxonomy The common moorhen was Species description, formally described in 1758 by the Swedish naturalist Carl Linnaeus in the 10th edition of Systema Naturae, tenth edition of his ''Systema Naturae''. He placed it in the genus ''Fulica (genus), Fulica'' and coined the binomial nomenclature, binomial name ''Fulica chloropus''. The common moorhen is now one of five extant species placed in the genus ''Gallinula'' that was introduced in 1760 by the French zoologist Mathurin Jacques Brisson. The genus name is ...

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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lesser Moorhen
The lesser moorhen (''Paragallinula angulata'') is a species of bird in the family Rallidae. It is sometimes placed into the genus '' Gallinula''. It is the only member of the genus ''Paragallinula''. Taxonomy The lesser moorhen was formerly placed in the genus '' Gallinula,'' but a 2015 molecular genetic study demonstrated that ''Gallinula'' was composed of four distinct lineages. The genus was split into four genera: ''Gallinula (sensu stricto), Paragallinula, Porphyriops,'' and ''Tribonyx.'' ''P. angulata'' is the only known species of ''Paragallinula'' which makes ''Paragallinula'' a monotypic genus. The name paragallinula comes from the Greek ''para'' 'beside' and the genus ''Gallinula.'' It is named for its similarity with the members of ''Gallinula'', but it also indicates its unique genetic lineage. Distribution The lesser moorhen is widely spread across Sub-Saharan Africa (excluding Southern Africa and Madagascar). It was once recorded in the Western Palearctic as ...

Rail (bird)
Rails (avian family Rallidae) are a large, Cosmopolitan distribution, cosmopolitan family (biology), family of small- to medium-sized terrestrial and/or semi-amphibious birds. The family exhibits considerable diversity in its forms, and includes such ubiquitous species as the crakes, coots, and gallinule; other rail species are extremely rare or endangered. Many are associated with wetland habitats, some being semi-aquatic like waterfowl (such as the coot), but many more are wading birds or shorebirds. The ideal rail habitats are marsh areas, including rice paddy, rice paddies, and flooded fields or open forest. They are especially fond of dense vegetation for nesting.Horsfall & Robinson (2003): pp. 206–207 The rail family is found in every Terrestrial animal, terrestrial habitat with the exception of dry desert, Polar climate, polar or freezing regions, and Alpine climate, alpine areas (above the snow line). Members of Rallidae occur on every continent except Antarctica. N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tasmania Parks And Wildlife Service
Tasmania Parks and Wildlife Service is the government body responsible for managing 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, and to replace the former Scenery Preservation and Animals & Birds Protection Boards, previously responsible for scenic reserves (including national parks) and wildlife sanctuaries respectively. The new service initially had a staff of 59 under inaugural Director Peter Murrell. The '' National Parks and Wildlife Act 1970'' had made new ...

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 an 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. The study of feathers is called plumology (or plumage science). People use feathers in many ways that are practical, cultural, and religious. 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 clothing and outdoor bedding, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 , created by Jacques Larivée ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
