Koel (other)
The true koels, ''Eudynamys'', are a genus of cuckoos from Asia, Australia and the Pacific. They are large sexually dimorphic cuckoos that eat fruits and insects and have loud distinctive calls. They are brood parasites, laying their eggs in the nests of other species. Taxonomy The genus ''Eudynamys'' was introduced in 1827 by the English naturalists Nicholas Vigors and Thomas Horsfield. The name combines the Ancient Greek ''eu'' meaning "fine" with ''dunamis'' meaning "power" or "strength". The type species was designated as the Pacific koel by George Robert Gray in 1840. A molecular genetic study by Sorenson and Payne (2005) found that the closest relative of ''Eudynamys'' is the dwarf koel (''Microdynamis parva''), and beyond that the thick-billed cuckoo (''Pachycoccyx audeberti''). They found that the long-tailed cuckoo (''Urodynamis taitensis'') of New Zealand and the Pacific, which had earlier been placed in ''Eudynamys'' as ''E. taitensis'' and sometimes called t ...

Nicholas Aylward Vigors
Nicholas Aylward Vigors (1785 – 26 October 1840) was an Ireland, Irish zoologist and politician. He popularized the classification of birds on the basis of the quinarian system. Early life Vigors was born at Old Leighlin, County Carlow on 1785 as first son from Capt. Nicholas Aylward Vigors which served in 29th (Worcestershire) Regiment of Foot, 29th (Worcestershire) Regiment and, his first wife, Catherine Vigors, daughter of Solomon Richards of Solsborough. He matriculated at Trinity College, Oxford on November 1803 before he was admitted at Lincoln's Inn on November 1806. Without completing his studies, he served in the army during the Peninsular War from 1809 to 1811 and wounded in Battle of Barrosa, Battle of Barossa on 5 March 1811. Though, he haven't completed his studies yet, he still published "An inquiry into the nature and extent of poetick licence" in London at 1810. He then returned to Oxford to continued his studies and achieved his Bachelor of Arts on 1817 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anthochaera
''Anthochaera'' is a genus of birds in the honeyeater family. The species are endemic to Australia and include the little wattlebird, the red wattlebird, the western wattlebird, and the yellow wattlebird. A molecular phylogenetic study has shown that the regent honeyeater also belongs in this genus. Description Of the five species in the genus only the yellow wattlebird (''Anthochaera paradoxa'') and the red wattlebird (''A. carunculata'') have the wattles of their common name. These are bare fleshy appendages, usually wrinkled and often brightly coloured, hanging from the cheeks, neck or throat, and presumably serving for display. A common name for species of the genus is wattlebird, a term also used for unrelated avian species. Taxonomy The genus ''Anthochaera'' was introduced in 1827 by the naturalists Nicholas Aylward Vigors and Thomas Horsfield. The name is derived from the Greek ''anthos'' meaning flower or bloom and ''khairō'' meaning to enjoy. The type species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noisy Miner
The noisy miner (''Manorina melanocephala'') is a bird in the honeyeater family, Meliphagidae, and is endemic to eastern and southeastern Australia. This miner is a grey bird, with a black head, orange-yellow beak and feet, a distinctive yellow patch behind the eye, and white tips on the tail feathers. The Tasmanian race has a more intense yellow panel in the wing, and a broader white tip to the tail. Males, females and juveniles are similar in appearance, though young birds are a brownish-grey. As the common name suggests, the noisy miner is a vocal species with a large range of songs, calls, scoldings and alarms, and almost constant vocalisations, particularly from young birds. One of four species in the genus ''Manorina'', the noisy miner itself is divided into four subspecies. The separation of the Tasmanian ''M. m. leachi'' is of long standing, and the mainland birds were further split in 1999. Found in a broad arc from Far North Queensland through New South Wales ...

Function (biology)
In evolutionary biology, function is the reason some object or process occurred in a system that evolved through natural selection. That reason is typically that it achieves some result, such as that chlorophyll helps to capture the energy of sunlight in photosynthesis. Hence, the organism that contains it is more likely to survive and reproduce, in other words the function increases the organism's fitness. A characteristic that assists in evolution is called an adaptation; other characteristics may be non-functional spandrels, though these in turn may later be co-opted by evolution to serve new functions. In biology, function has been defined in many ways. In physiology, it is simply what an organ, tissue, cell or molecule does. In the philosophy of biology, talk of function inevitably suggests some kind of teleological purpose, even though natural selection operates without any goal for the future. All the same, biologists often use teleological language as a shorthand for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black-billed Koel
The black-billed koel (''Eudynamys melanorhynchus'') is a species of cuckoo in the family Cuculidae. It is Endemism, endemic to forest and woodland on the Indonesian islands of Sulawesi, Sula Islands, Sula, Banggai Island, Banggai, Togian Islands, Togian and other smaller nearby islands. It has often been considered conspecific with ''Eudynamys scolopaceus, E. scolopaceus'', but they are increasingly treated as separate species. Unlike the black-billed koel, all other members of the common koel (other), common koel Species complex, complex have a pale bill. The black billed koel voice a typical "koel!" call, or a short series of rising and falling "woo" notes.

Asian Koel
The Asian koel (''Eudynamys scolopaceus'') is a member of the cuckoo order of birds, the Cuculiformes. It is found in the Indian Subcontinent, China, and Southeast Asia. It forms a superspecies with the closely related black-billed koels, and Pacific koels which are sometimes treated as subspecies. The Asian koel like many of its related cuckoo kin is a brood parasite that lays its eggs in the nests of crows and other hosts, who raise its young. They are unusual among the cuckoos in being largely frugivorous as adults. The name ''koel'' is echoic in origin with several language variants. The bird is a widely used symbol in Indian and Nepali poetry. Taxonomy In 1747 the English naturalist George Edwards included an illustration and a description of the Asian koel in the second volume of his ''A Natural History of Uncommon Birds''. He used the English name "The Brown and Spotted Indian Cuckow". Edwards based his hand-coloured etching on a specimen from Bengal that belonged to ...

Species Complex
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...

Robert B
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can be use ...

White-crowned Cuckoo
The white-crowned cuckoo or white-crowned koel (''Cacomantis leucolophus'') is a species of cuckoo in the family Cuculidae. It was originally described by Salomon Müller as ''Cuculus leucolophus''. It was later placed in the monotypic genus ''Caliechthrus'', but most taxonomists place it the genus ''Cacomantis'' because it has a similar song to other cuckoos in this genus and it is genetically similar to the pallid cuckoo (''Cacomantis pallidus'').Payne, Robert B. (2005) ''The Cuckoos'', Oxford University Press. It is found in New Guinea and neighbouring Salawati Salawati is one of the four major islands in the Raja Ampat Islands in Southwest Papua (formerly West Papua), Indonesia. Its area is 1,623 km2.
