Black-chinned Weaver
The black-chinned weaver (''Ploceus nigrimentus'') is a species of bird in the family Ploceidae Ploceidae is a family of small passerine birds, many of which are called weavers, weaverbirds, weaver finches and bishops. These names come from the nests of intricately woven vegetation created by birds in this family. In most recent classifica ....

Anton Reichenow
Anton Reichenow (1 August 1847 in Charlottenburg – 6 July 1941 in Hamburg) was a German ornithologist and herpetologist. Reichenow was the son-in-law of Jean Cabanis, and worked at the Natural History Museum of Berlin from 1874 to 1921. He was an expert on African birds, making a collecting expedition to West Africa in 1872 and 1873, and writing ''Die Vögel Afrikas'' (1900–05). He was also an expert on parrots, describing all species then known in his book ''Vogelbilder aus Fernen Zonen: Abbildungen und Beschreibungen der Papageien'' (illustrated by Gustav Mützel, 1839–1893). He also wrote ''Die Vögel der Bismarckinseln'' (1899). He was editor of the ''Journal für Ornithologie'' from 1894 to 1921. A number of birds are named after him, including Reichenow's woodpecker and Reichenow's firefinch. His son Eduard Reichenow was a famous protozoologist. Reichenow is known for his classification of birds into six groups, described as "shortwings, swimmers, stiltbirds, skinb ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...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 ...

Ploceidae
Ploceidae is a family of small passerine birds, many of which are called weavers, weaverbirds, weaver finches and bishops. These names come from the nests of intricately woven vegetation created by birds in this family. In most recent classifications, Ploceidae is a clade, which excludes some birds that have historically been placed in the family, such as some of the sparrows, but which includes the monotypic subfamily Amblyospizinae. The family is believed to have originated in the mid-Miocene. All birds of the Ploceidae are native to the Old World, most in Africa south of the Sahara, though a few live in tropical areas of Asia. A few species have been introduced outside their native range. Taxonomy and systematics The family Ploceidae was introduced (as Ploceïdes) by the Swedish zoologist Carl Jakob Sundevall in 1836. Phylogenetic studies have shown that the family is sister to a clade containing the families Viduidae and Estrildidae Their common ancestor lived in the middl ...

Ploceus
''Ploceus'' is a genus of birds in the weaver family, Ploceidae. They are native to the Indomalayan and Afrotropical realms. Taxonomy and systematics Phylogeny The genus ''Ploceus'' was introduced by the French naturalist Georges Cuvier in 1816. The type species was subsequently designated as the baya weaver. The genus name is from Ancient Greek πλοκευς ''plokeus'' meaning "weaver", and is derived from the Greek word πλεκω ''plekō'' "to entwine". Based on recent DNA-analysis, the genus ''Ploceus'' is almost certainly polyphyletic. If all species currently included in the genus would remain and the genus would be made monophyletic, it would have to encompass the entire subfamily Ploceinae. The Ploceinae can be divided into two groups. In the first group, the widowbirds and bishops (genus '' Euplectes'') are sister to a clade in which the genera ''Foudia'' and ''Quelea'' are closest relatives and which further includes the Asiatic species of ''Ploceus'', i.e. ...
