Guadalcanal Dwarf Kingfisher
The Guadalcanal dwarf kingfisher (''Ceyx nigromaxilla''), is a species of bird in the family Alcedinidae that is endemic to Guadalcanal Island. Its natural habitat is sub-tropical or tropical moist lowland forests. This species was formerly considered one of the 15 recognised subspecies of what was then known as the variable dwarf kingfisher (''Ceyx lepidus'' or ''Alcedo lepidus''). A molecular phylogenetic study published in 2013 found that most of the insular subspecies had substantially diverged from one another. The variable dwarf kingfisher was therefore split and 12 of the subspecies, including the Guadalcanal dwarf kingfisher, were promoted to species status. At the same time the name of the variable dwarf kingfisher was changed to the Moluccan dwarf kingfisher The Moluccan dwarf kingfisher (''Ceyx lepidus''), formerly known as the variable dwarf kingfisher, is a species of bird in the family Alcedinidae.

Walter Rothschild, 2nd Baron Rothschild
Lionel Walter Rothschild, 2nd Baron Rothschild, Baron de Rothschild, (8 February 1868 – 27 August 1937) was a British banker, politician, zoologist and soldier, who was a member of the Rothschild family. As a Zionist leader, he was presented with the Balfour Declaration, which pledged British support for a Jewish national home in Palestine. Rothschild was the president of the Board of Deputies of British Jews from 1925 to 1926. Early life Walter Rothschild was born in London as the eldest son and heir of Emma Louise von Rothschild and Nathan Rothschild, 1st Baron Rothschild, an immensely wealthy financier of the international Rothschild financial dynasty and the first Jewish peer in England. The eldest of three children, Walter was deemed to have delicate health and was educated at home. As a young man, he travelled in Europe, attending the University of Bonn for a year before entering Magdalene College, Cambridge. In 1889, leaving Cambridge after two years, he was ...

Ernst Hartert
Ernst Johann Otto Hartert (29 October 1859 – 11 November 1933) was a widely published German ornithologist. Life and career Hartert was born in Hamburg, Germany on 29 October 1859. In July 1891, he married the illustrator Claudia Bernadine Elisabeth Hartert in Frankfurt am Main, Germany, with whom he had a son named Joachim Karl (Charles) Hartert, (1893–1916), who was killed as an English soldier on the Somme. Together with his wife, he was the first to describe the blue-tailed Buffon hummingbird subspecies (''Chalybura buffonii intermedia'' Hartert, E & Hartert, C, 1894). The article ''On a collection of Humming Birds from Ecuador and Mexico'' appears to be their only joint publication. Hartert was employed by Walter Rothschild, 2nd Baron Rothschild as ornithological curator of Rothshild's private Natural History Museum at Tring, in England from 1892 to 1929. Hartert published the quarterly museum periodical ''Novitates Zoologicae'' (1894–39) with Rothschild, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Guadalcanal Island
Guadalcanal (; indigenous name: ''Isatabu'') is the principal island in Guadalcanal Province of Solomon Islands, located in the south-western Pacific, northeast of Australia. It is the largest island in the Solomon Islands by area, and the second by population (after Malaita). The island is mainly covered in dense tropical rainforest and has a mountainous hinterland. Guadalcanal's first charting by westerners was under the Spanish expedition of Álvaro de Mendaña in 1568. The name comes from the village of Guadalcanal, in the province of Seville, in Andalusia, Spain, birthplace of Pedro de Ortega Valencia, a member of Mendaña's expedition. During 1942–43, it was the scene of the Guadalcanal Campaign and saw bitter fighting between Japanese and US troops. The Americans were ultimately victorious. At the end of World War II, Honiara, on the north coast of Guadalcanal, became the new capital of the British Solomon Islands Protectorate. Geography Guadalcanal is the l ...

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 ...

Variable Dwarf Kingfisher
Variable dwarf kingfisher is a common name of a group of kingfishers in the genus, '' Ceyx''. The variable dwarf kingfisher (''Ceyx lepidus'' or ''Alcedo lepidus'') formerly included 15 subspecies. A molecular phylogenetic study published in 2013 found that most of the insular subspecies had substantially diverged from one another. The variable dwarf kingfisher was therefore split and 12 of the subspecies were promoted to species status. At the same time the name of the variable dwarf kingfisher was changed to the Moluccan dwarf kingfisher. The species in the group are: * Moluccan dwarf kingfisher, ''Ceyx lepidus'' * Dimorphic dwarf kingfisher, ''Ceyx margarethae'' * Sula dwarf kingfisher, ''Ceyx wallacii'' * Buru dwarf kingfisher, ''Ceyx cajeli'' * Papuan dwarf kingfisher, ''Ceyx solitarius'' * Manus dwarf kingfisher, ''Ceyx dispar'' * New Ireland dwarf kingfisher, ''Ceyx mulcatus'' * New Britain dwarf kingfisher, ''Ceyx sacerdotis'' * North Solomons dwarf kingfisher ...

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Moluccan Dwarf Kingfisher
The Moluccan dwarf kingfisher (''Ceyx lepidus''), formerly known as the variable dwarf kingfisher, is a species of bird in the family Alcedinidae. Taxonomy This species was previous named the variable dwarf kingfisher and had 15 recognised subspecies. A molecular phylogenetic study published in 2013 found that most of the taxa had substantially diverged from each other. The species was therefore split and 12 of the subspecies were promoted to species status. At the same time the name was changed to the Moluccan dwarf kingfisher. Some taxonomic authorities further split this species into the Seram dwarf kingfisher, and refer to the other group as the North Moluccan dwarf kingfisher. The Seram dwarf kingfisher is then limited to the southern Moluccas. Distribution This species is endemic to the Moluccas. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malaita Dwarf Kingfisher
The Malaita dwarf kingfisher (''Ceyx malaitae''), is a species of bird in the family Alcedinidae that is endemic to Malaita Island. Its natural habitat is subtropical or tropical moist lowland forests.

Ceyx (bird)
''Ceyx'' is an Old World genus of river kingfishers. These kingfishers are found from South East Asia to the Solomon Islands. The genus was introduced by the French naturalist Bernard Germain de Lacépède in 1799, and derives its name from the Greek myth of Alcyone and Ceyx. The type species is the oriental dwarf kingfisher (''Ceyx erithaca''). A molecular phylogenetic study of the alcedinine kingfishers published in 2007 found that the genera as then defined did not form monophyletic groups. The species were subsequently rearranged into four monophyletic genera. The little kingfisher, azure kingfisher, Bismarck kingfisher, silvery kingfisher and Indigo-banded kingfisher were moved from ''Alcedo'' to ''Ceyx''. All except one of the birds in the reconstituted genus have three rather than the usual four toes. The exception is the Sulawesi dwarf kingfisher which retains a vestigial fourth toe. The Moluccan dwarf kingfisher (''Ceyx lepidus'') was previous named the variable d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
