Rennell Fantail
The Rennell fantail (''Rhipidura rennelliana'') is a species of bird in the family Rhipiduridae. It is endemic to Rennell Island (Solomon Islands). Its natural habitat is subtropical or tropical moist lowland forests. Description The plumage is mostly mouse-brown, while the color of throat is somewhat paler. There is a reddish stripe on the wing. The long tail, which the bird often spreads, is with a pale fringe. Avoids open spaces, preferring forest (mostly virgin ones). This is the only fantail on Rennell Island. The usual sound is piercing and squeaky.: photos, description and range map Taxonomy Rennell fantail (''R. rennelliana'') forms a superspecies with: * Brown fantail (''R. drownei'') * Makira fantail (''R. tenebrosa'') * Streaked fantail (''R. verreauxi'') * Kadavu fantail (''R. personata'') * Samoan fantail (''R. nebulosa'') References Rennell fantail Birds of Rennell Island Rennell fantail The Rennell fantail (''Rhipidura rennelliana'') is a species ...

Ernst Mayr
Ernst Walter Mayr (; 5 July 1904 – 3 February 2005) was one of the 20th century's leading evolutionary biologists. He was also a renowned Taxonomy (biology), taxonomist, tropical explorer, ornithologist, Philosophy of biology, philosopher of biology, and History of science, historian of science. His work contributed to the conceptual revolution that led to the Modern synthesis (20th century), modern evolutionary synthesis of Gregor Mendel, Mendelian genetics, systematics, and Charles Darwin, Darwinian evolution, and to the development of the Species, biological species concept. Although Charles Darwin and others posited that multiple species could evolve from a single common ancestor, the mechanism by which this occurred was not understood, creating the ''species problem''. Ernst Mayr approached the problem with a new definition for species. In his book ''Systematics and the Origin of Species'' (1942) he wrote that a species is not just a group of Morphology (biology), morph ...

Bird
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. B ...

Rhipiduridae
The family Rhipiduridae are small insectivorous birds of Australasia, Southeast Asia and the Indian subcontinent that includes the fantails and silktails. Taxonomy and systematics There are four genera classified within the family: * Subfamily Rhipidurinae: **''Rhipidura'' – typical fantails (51 species) *Subfamily Lamproliinae: **'' Chaetorhynchus'' – drongo fantail **'' Eutrichomyias'' – cerulean flycatcher **''Lamprolia The silktails are a group of birds endemic to Fiji.

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rennell Island
Rennell Island, locally known as Mugaba, is the main island of two inhabited islands that make up the Rennell and Bellona Province in the nation state of Solomon Islands. Rennell Island has a land area of that is about long and wide. It is the second largest raised coral atoll in the world with the largest lake in the insular Pacific, Lake Tegano, a lake that is listed as a World Heritage Site. Rennell Island has a population of about 1,840 persons of Polynesian descent who primarily speak Rennellese, Pijin and some English. Rennell and Bellona Islands are two of the few islands in the otherwise Melanesian Solomon Islands archipelago classified as a Polynesian outlier; others being Sikaiana, Ontong Java, Tikopia, Anuta, Duff Islands, and some Reef Islands. The island lies south of Honiara and north-east of Brisbane. The provincial capital, Tigoa, is at the western end of the island.

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

Kadavu Fantail
The Kadavu fantail (''Rhipidura personata'') is a species of bird in the fantail family Rhipiduridae. It is endemic to Kadavu and Ono in the Kadavu archipelago, in southern Fiji. It is closely related to the streaked fantail of the rest of Fiji, and forms a superspecies with the numerous island species of fantail ranging from the Solomon Islands (the brown fantail) to Samoa (the Samoan fantail). The Kadavu fantail is restricted to tropical moist lowland forests, where it feeds by flycatching for insects. It sometimes joins mixed-species feeding flocks with Polynesian trillers, Fiji bush warblers and silvereyes. The breeding season is October and November. It is threatened by habitat loss.
