Buff-headed Coucal
The buff-headed coucal (''Centropus milo'') is a species of coucal. These are often placed in the cuckoo family (Cuculidae) but seem to warrant recognition as a distinct family. ''C. milo'' is a common endemic of the central islands of the Solomon Islands. Its natural habitat is tropical moist lowland and mountain forests, mostly in primary and secondary growth. This species is a large cuckoo with a heavy bill and short wings. In total length, this species may measure . With a body mass of , this may be not only the largest coucal, apparently outweighing other very large coucals like the goliath coucal, but possibly the largest of all cuckoos, with a slightly higher cited weight than even the channel-billed cuckoo, usually considered the world's largest cuckoo. The plumage of adults is striking with a buff head, upper back and undersides, and glossy black wings, lower back and tail. The iris is red and legs and bill are dark grey. Juveniles are very differently colored, with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Gould
John Gould (; 14 September 1804 – 3 February 1881) was an English ornithologist. He published a number of monographs on birds, illustrated by plates produced by his wife, Elizabeth Gould, and several other artists, including Edward Lear, Henry Constantine Richter, Joseph Wolf and William Matthew Hart. He has been considered the father of bird study in Australia and the Gould League in Australia is named after him. His identification of the birds now nicknamed "Darwin's finches" played a role in the inception of Darwin's theory of evolution by natural selection. Gould's work is referenced in Charles Darwin's book, ''On the Origin of Species''. Early life Gould was born in Lyme Regis, the first son of a gardener. Both father and son probably had little education. After working on Dowager Lady Poulett's glass house, his father obtained a position on an estate near Guildford, Surrey, and then in 1818, Gould Snr became foreman in the Royal Gardens of Windsor. Gould then be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plumage
Plumage ( "feather") is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morphs. The placement of feathers on a bird is not haphazard, but rather emerge in organized, overlapping rows and groups, and these are known by standardized names. Most birds moult twice a year, resulting in a breeding or ''nuptial plumage'' and a ''basic plumage''. Many ducks and some other species such as the red junglefowl have males wearing a bright nuptial plumage while breeding and a drab ''eclipse plumage'' for some months afterward. The painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the ''juvenile plumage'' with an ''auxiliary formative plumage''; the second a month or so l ...

Birds Of Guadalcanal
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Centropus
A coucal is one of about 30 species of birds in the cuckoo family. All of them belong in the subfamily Centropodinae and the genus ''Centropus''. Unlike many Old World cuckoos, coucals are not brood parasites, though they do have their own reproductive peculiarity: all members of the genus are (to varying degrees) sex-role reversed, so that the smaller male provides most of the parental care. At least one coucal species, the black coucal, is polyandrous. Some species (''Centropus phasianinus'') have the male investing more in incubation and parental care. Taxonomy The genus ''Centropus'' was introduced in 1811 by the German zoologist Johann Karl Wilhelm Illiger. The type species was subsequently designated as the Senegal coucal by George Robert Gray in 1840. The genus name combines the Ancient Greek ''kentron'' meaning "spur" or "spike" with ''pous'' meaning "foot". Description Many coucals have a long claw on their hind toe (hallux). The feet have minute spurs and this is respon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Object Identifier
A digital object identifier (DOI) is a persistent identifier or handle used to uniquely identify various objects, standardized by the International Organization for Standardization (ISO). DOIs are an implementation of the Handle System; they also fit within the URI system ( Uniform Resource Identifier). They are widely used to identify academic, professional, and government information, such as journal articles, research reports, data sets, and official publications. DOIs have also been used to identify other types of information resources, such as commercial videos. A DOI aims to resolve to its target, the information object to which the DOI refers. This is achieved by binding the DOI to metadata about the object, such as a URL where the object is located. Thus, by being actionable and interoperable, a DOI differs from ISBNs or ISRCs which are identifiers only. The DOI system uses the indecs Content Model for representing metadata. The DOI for a document remains fixed over t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helm Identification Guides
The ''Helm Identification Guides'' are a series of books that identify groups of birds. The series include two types of guides, those that are: * Taxonomic, dealing with a particular family of birds on a worldwide scale—most early Helm Guides were this type, as well as many more-recent ones, although some later books deal with identification of such groups on a regional scale only (e.g., ''The Gulls Guide,'' which covers only species in Europe, Asia, and North America) * Geographic, including all bird species in an area (e.g., ''The Birds of the West Indies'') Early volumes were sometimes published under the Croom Helm or Christopher Helm imprints. In addition, a parallel set of guides, very similar in design, was published by Pica Press in the 1990s (marked ''Pica'' in the list below); Pica was later absorbed into A & C Black (now part of Bloomsbury Publishing Plc), and all guides are now marketed as a single series. Several of the books have won the British Birds ''Bird B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marovo Language
Marovo is an Austronesian language of the Solomon Islands. It is spoken in the New Georgia Group on islands in Marovo Lagoon and on the neighbouring islands of New Georgia, Vangunu and Nggatokae. The usual word order in sentences is verb- subject-object. Names for local fauna are similar to but still much distinct from those in Roviana (and presumably other New Georgia languages). Footnotes References * External links * Materials on Marovo are included in the open access Arthur Capell collectionsAC1anAC2 held by Paradisec The Pacific and Regional Archive for Digital Sources in Endangered Cultures (PARADISEC) is a cross-institutional project that supports work on endangered languages and cultures of the Pacific and the region around Australia.

Roviana Language
Roviana is a member of the North West Solomonic branch of Oceanic languages. It is spoken around Roviana and Vonavona lagoons at the north central New Georgia in the Solomon Islands. It has 10,000 first-language speakers and an additional 16,000 people mostly over 30 years old speak it as a second language (Raymond 2005). In the past, Roviana was widely used as a trade language and further used as a lingua franca especially for church purposes in the Western Province but now it is being replaced by the Solomon Islands Pijin. Few published studies on Roviana language include: Ray (1926), Waterhouse (1949) and Todd (1978) contain the syntax of Roviana language. Corston-Oliver (1996 & 2002) discuss about the ergativity in Roviana. Todd (2000) and Ross (1988) discuss the clause structure in Roviana. Schuelke (2020) discusses grammatical relations and syntactic ergativity in Roviana. Phonology and orthography Consonants The Roviana alphabet is based on the Latin alphabet and con ...

Touo Language
The Touo language, also known as ''Baniata'' (''Mbaniata'') or ''Lokuru'', is spoken over the southern part of Rendova Island, located in the Western Province of the Solomon Islands. Classification Touo is generally seen to be a member of the tentative Central Solomons family, although Glottolog considers it an isolate. Pedrós (2015) cautiously suggests Lavukaleve as the closest relative to Touo. Most of the surrounding languages to Touo belong to the Oceanic subgroup of the Austronesian language family. Names The Touo language is sometimes called the ''Baniata'' (''Mbaniata'') or ''Lokuru'' language, after the largest two villages where the language is spoken. The word ''Touo'' comes from the ethnonym that Touo speakers use to refer to themselves. Phonology Consonants Touo consonants are: : Vowels Touo vowels have phonemically contrastive tense/lax vowels. Some minimal pairs showing the tense/lax vowel phonemic distinction in Touo: : Grammar Word order in Touo is SO ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pheasant Coucal
The pheasant coucal (''Centropus phasianinus'') is a species of cuckoo in the family Cuculidae. It is found in Australia, Timor and New Guinea. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical mangrove forests. It has adapted well to canefields in northern Australia. The pheasant coucal is unusual among Australian cuckoos in that it incubates and raises its own young instead of laying its eggs in the nest of another species. Taxonomy The ornithologist John Latham described the pheasant coucal as ''Cuculus phasianinus'' in 1801, based on a drawing by Thomas Watling. Six subspecies are recognised, two of which are found in Australia with an abrupt demarcation between them occurring around the Burdekin River in Central Queensland. South is the nominate subspecies ''phasianinus'', while north is the subspecies ''melanurus'', which is larger in size and has darker and more prominent black bands on its rectrices. The little known subspe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allopatric
Allopatric speciation () – also referred to as geographic speciation, vicariant speciation, or its earlier name the dumbbell model – is a mode of speciation that occurs when biological populations become geographically isolated from each other to an extent that prevents or interferes with gene flow. Various geographic changes can arise such as the movement of continents, and the formation of mountains, islands, bodies of water, or glaciers. Human activity such as agriculture or developments can also change the distribution of species populations. These factors can substantially alter a region's geography, resulting in the separation of a species population into isolated subpopulations. The vicariant populations then undergo genetic changes as they become subjected to different selective pressures, experience genetic drift, and accumulate different mutations in the separated populations' gene pools. The barriers prevent the exchange of genetic information between t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
