Chestnut-backed Sparrow-weaver
The chestnut-backed sparrow-weaver (''Plocepasser rufoscapulatus'') 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 ....

Johann Büttikofer
Dr. Johann Büttikofer (9 August 1850 – 24 June 1927) was a Swiss zoologist. Büttikofer was born in Ranflüh (part of Rüderswil, Canton of Bern) in the Emmental. He is best known for his two zoological expeditions to the Republic of Liberia (1879 to 1882 and 1886 to 1887) and resulting publications; from 1897 to 1924 he was the Director of the Blijdorp Zoological Garden in Rotterdam. After his retirement he settled in Bern, Switzerland. For his extensive contributions to the knowledge of Liberian fauna he is regarded as the 'Father of Liberian Natural History'. Scientific career Johann Büttikofer learned his love of nature from his father Jakob, who was a school teacher in his native Ranflüh. He attended village school until the age of 16 and then studied French for one year, after which he attended a teacher training college in Hofwil until the age of 20. He taught school in Graswil, Switzerland for six years, hunted, began to learn taxidermy, read travel accounts, and lon ... [...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 ...

Plocepasser
The sparrow-weavers (''Plocepasser'') are a genus of birds in the family Ploceidae (weavers), but some taxonomic authorities place them in the family Passeridae (Old World sparrows). Taxonomy and systematics The genus ''Plocepasser'' contains the following species: Phylogeny Based on recent DNA-analysis (which only included ''P. mahali''), the genus ''Plocepasser'' belongs to the group of sparrow weavers (subfamily Plocepasserinae), and is most related to the clade that consists of '' Philetairus socius'' and the genus ''Pseudonigrita''. This clade is sister A sister is a woman or a girl who shares one or more parents with another individual; a female sibling. The male counterpart is a brother. Although the term typically refers to a family, familial relationship, it is sometimes used endearingly to r ... to the most basic genus of the subfamily, '' Sporopipes''. Provided that genera are correct clades, the following tree expresses current insights. References Exter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taxa Named By Johann Büttikofer
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
