African Dwarf Kingfisher
''This article discusses the African dwarf kingfisher, which is distinct from the Oriental dwarf kingfisher.'' The African dwarf kingfisher (''Ispidina lecontei'') is a species of kingfisher in the Alcedininae subfamily. Taxonomy The African dwarf kingfisher was described in 1856 by the American ornithologist John Cassin from a specimen collected by Paul Du Chaillu. Cassin introduced the current binomial name ''Ispidina lecontei''. The specific epithet was chosen in honour of the entomologist John Lawrence LeConte. There are two subspecies: * ''I. l. ruficeps'' Hartlaub, 1857 – Sierra Leone to Ghana, west of the Dahomey gap in the rainforest. * ''I. l. lecontei'' Cassin, 1856 – south Nigeria to west South Sudan, Uganda and central Democratic Republic of the Congo; central Angola. Description This is the world's smallest kingfisher with a length of and a weight of . Distribution It inhabits African rainforests and is found in Angola, Cameroon, Central African Republic, R ...

Oriental Dwarf Kingfisher
The oriental dwarf kingfisher (''Ceyx erithaca''), also known as the black-backed kingfisher or three-toed kingfisher, is a pocket-sized bird in the family Alcedinidae. This tropical kingfisher is a partial migrant that is endemic across much of the Indian Subcontinent and Southeast Asia. It resides in lowland forests, typically near streams or ponds, where it feeds upon insects, spiders, worms, crabs, fish, frogs, and lizards. This small bird is easily distinguishable from other birds in its range due to its red bill, yellow-orange underparts, lilac-rufous upperparts, and blue-black back. Description The oriental dwarf kingfisher is one of the smallest known kingfisher species. It is only slightly larger than a medium-sized hummingbird and measures 12.5–14 cm in length (including bill and tail). Females typically weigh 14-16g and males 14-21.5g, making the males slightly larger. The two sexes are otherwise alike and sexual dimorphism is not present. Both males and f ...

John Gerrard Keulemans
Johannes Gerardus Keulemans (J. G. Keulemans) (8 June 1842 – 29 March 1912) was a Dutch bird illustrator. For most of his life he lived and worked in England, illustrating many of the best-known ornithology books of the nineteenth century. Biography Keulemans was born in Rotterdam. As a young man he collected animal specimens for museums such as the Natural History Museum in Leiden, whose director, Hermann Schlegel, encouraged Keulemans and sent him on the 1864 expedition to West Africa. In 1869, he was persuaded by Richard Bowdler Sharpe to illustrate his '' Monograph of the Alcedinidae, or Family of Kingfishers'' (1868-1871) and to move to England, where he lived for the rest of his life. He was married twice, and had eight children by his first wife and seven children by his second wife. Only nine of his children reached adulthood. He also wrote topics on spirituality, and claimed he had a premonition at the moment of death of one of his sons. He died in Ilford, Essex (now ...

John Cassin
John Cassin (September 6, 1813 – January 10, 1869) was an American ornithologist from Pennsylvania. He worked as curator and Vice President at the Philadelphia Academy of Natural Sciences and focused on the systemic classification of the Academy's extensive collection of birds. He was one of the founders of the Delaware County Institute of Science and published several books describing 194 new species of birds. Five species of North American birds, a cicada and a mineral are named in his honor. Early life and education Cassin was born in Upper Providence Township, Pennsylvania on September 6, 1813. He was educated at the Westtown School in Westtown, Pennsylvania. His great Uncle, John Cassin, was a commodore in the U.S. Navy and served in the War of 1812. He served in the Union Army during the American Civil War and was held prisoner in the infamous Confederate Libby Prison in Richmond, Virginia. Career Cassin moved to Philadelphia in 1834 and became the head of a lith ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kingfisher
Kingfishers are a family, the Alcedinidae, of small to medium-sized, brightly colored birds in the order Coraciiformes. They have a cosmopolitan distribution, with most species found in the tropical regions of Africa, Asia, and Oceania, but also can be seen in Europe. They can be found in deep forests near calm ponds and small rivers. The family contains 114 species and is divided into three subfamilies and 19 genera. All kingfishers have large heads, long, sharp, pointed bills, short legs, and stubby tails. Most species have bright plumage with only small differences between the sexes. Most species are tropical in distribution, and a slight majority are found only in forests. They consume a wide range of prey usually caught by swooping down from a perch. While kingfishers are usually thought to live near rivers and eat fish, many species live away from water and eat small invertebrates. Like other members of their order, they nest in cavities, usually tunnels dug into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Kingfishers
The river kingfishers or pygmy kingfishers, subfamily Alcedininae, are one of the three subfamilies of kingfishers. The river kingfishers are widespread through Africa and east and south Asia as far as Australia, with one species, the common kingfisher (''Alcedo atthis'') also appearing in Europe and northern Asia. This group includes many kingfishers that actually dive for fish. The origin of the subfamily is thought to have been in Asia. These are brightly plumaged, compact birds with short tails, large heads, and long bills. They feed on insects or fish, and lay white eggs in a self-excavated burrow. Both adults incubate the eggs and feed the chicks. Taxonomy A molecular phylogenetic study of the river 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. A clade containing four species were placed in the resurrected genus ''Corythornis'' and five species ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paul Du Chaillu
Paul Belloni Du Chaillu (July 31, 1831 (disputed)April 29, 1903) was a French-American traveler, zoologist, and anthropologist. He became famous in the 1860s as the first modern European outsider to confirm the existence of gorillas, and later the Pygmy people of central Africa. He later researched the prehistory of Scandinavia. Early life and parentage There are conflicting reports of both the year and place of Du Chaillu's birth. The year is variously given as 1831 (the consensus of modern scholars), 1835, or 1839; the date when given is July 31. Accounts usually cite either Paris or New Orleans as his likely place of birth. A contemporary obituary quotes a statement made by Du Chaillu referring to "the United States, my country by adoption, and ... France, my native land." His entry in the 1901-1902 edition of ''Marquis Who's Who'' — which was based on information he supplied directly to the editors — says 1838 in New Orleans.

Binomial Name
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

Gustav Hartlaub
Karel Johan Gustav Hartlaub (8 November 1814 – 29 November 1900) was a German physician and ornithologist. Hartlaub was born in Bremen, and studied at Bonn and Berlin before graduating in medicine at Göttingen. In 1840, he began to study and collect exotic birds, which he donated to the Bremen Natural History Museum. He described some of these species for the first time. In 1852, he set up a new journal with Jean Cabanis, the ''Journal für Ornithologie''. He wrote with Otto Finsch, ''Beitrag zur Fauna Centralpolynesiens: Ornithologie der Viti-, Samoa und Tonga- Inseln''. Halle, H. Schmidt. This 1867 work which has handcoloured lithographs was based on bird specimens collected by Eduard Heinrich Graeffe for Museum Godeffroy. A number of birds were named for him, including Hartlaub's Bustard, Hartlaub's Turaco, Hartlaub's Duck, and Hartlaub's Gull Hartlaub's gull (''Chroicocephalus hartlaubii''), also known as the king gull, it is a small gull.

Dahomey Gap
In West Africa, the Dahomey Gap refers to the portion of the Guinean forest-savanna mosaic that extends all the way to the coast in Benin, Togo, and Ghana, thus separating the forest zone that covers much of the south of the region into two separate parts. The forest region west of the gap is called the Upper Guinean forests or Guinean forest zone, and the portion east of the gap is called the Lower Guinean forests, Lower Guinean-Congolian forests, or Congolian Forest Zone. The major city in the Gap is Accra. Several other cities, such as Kumasi, exist on the fringe of the Gap. Causes of dryness The dryness of the Dahomey Gap is unusual, given that it lies surrounded by a very wet monsoon belt on all sides, and no mountains block moisture. Yet, Accra, which is in the heart of the Gap, receives only of rainfall per year — less than half the amount needed to sustain tropical rainforest (which would be expected at a latitude of 6° N). The cause of the dryness of the Dahomey ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
