Red-backed Mannikin
The black-and-white mannikin (''Spermestes bicolor'') also black-and-white munia or red-backed mannikin, is a species of estrildid finch, widely occurring throughout the African tropical rainforest. It has an estimated global extent of occurrence of 4,200,000 km2. It is found in moist savanna and subtropical or tropical moist lowland forest habitat. The status of the species is evaluated as least concern. They are seedeaters, but are known to feed on algae. The black-and-white mannikin was formally described in 1843 by the British zoologist and collector Louis Fraser from a specimen collected near Cape Palmas in Liberia. He placed the species in the genus ''Amadina'' and coined the binomial name ''Amadina bicolor''. The black-and-white mannikin is now one of the four species placed in the genus ''Spermestes'' that was introduced in 1837 by William John Swainson. Four subspecies are recognised: * ''S. b. bicolor'' (Fraser, 1843) – Guinea-Bissau to Cameroon * ''S. b. poens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Douala
Douala is the largest city in Cameroon and its economic capital. It is also the capital of Cameroon's Littoral Region. Home to Central Africa's largest port and its major international airport, Douala International Airport (DLA), it is the commercial and economic capital of Cameroon and the entire CEMAC region comprising Gabon, Congo, Chad, Equatorial Guinea, Central African Republic and Cameroon. Consequently, it handles most of the country's major exports, such as oil, cocoa and coffee, timber, metals and fruits. , the city and its surrounding area had an estimated population of 5,768,400. The city sits on the estuary of Wouri River and its climate is tropical. History The first Europeans to visit the area were the Portuguese in about 1472. At the time, the estuary of Wouri River was known as the Rio dos Camarões (Shrimp River). By 1650, it had become the site of a town formed by immigrants, said to have arrived from Congo, who spoke the Duala language. During the 18th ...

Spermestes
''Spermestes'' is a genus of small seed-eating birds in the family Estrildidae. They are distributed across Sub-Saharan Africa. Taxonomy The genus ''Spermestes'' was introduced in 1837 by the English naturalist William John Swainson to accommodate the bronze mannikin. The name combines the Ancient Greek ''sperma'' meaning "seed" and ''-estēs'' meaning "-eater". Based on the results of a molecular phylogenetic study published in 2020, this genus was resurrected for a clade of species that were formerly assigned to the genera ''Lonchura ''Lonchura'' is a genus of the estrildid finch family, and includes munias (or minias) and mannikins.

Birds Of The African Tropical Rainforest
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. Birds ...

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.

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics ( morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks.

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 cred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis Fraser
Louis Fraser (1819 – c. 1883) was a British zoologist and collector. In his early years, Fraser was curator of the Museum of the Zoological Society of London.

Amadina
''Amadina'' is a genus of estrildid finches that are found in Africa. Taxonomy The genus ''Amadina'' was introduced in 1827 by the English naturalist William John Swainson with the cut-throat finch as the type species. The name ''Amadina'' is a corrupted diminutive of the genus name ''Ammodramus ''Ammodramus'' is a genus of birds in the family Passerellidae, in the group known as American sparrows. Birds of this genus are known commonly as grassland sparrows.Estrilda'', and created the name to reflect that linkage.
