Pseudonigrita
''Pseudonigrita'' is a genus of sparrow-like birds in the weaverbird family. Extant Species It contains two species, which are both found in eastern Africa: Taxonomy French naturalist Charles Lucien Bonaparte described the grey-capped social weaver as ''Nigrita arnaudi'' in 1850, based on a specimen collected by the French explorer Joseph Pons d'Arnaud around 1841 near Juba on the White Nile. In 1884, the black-capped social weaver was first described by German East-Africa explorer Gustav Fischer and German ornithologist Anton Reichenow as ''Nigrita cabanisi'', based on a specimen collected in 1883 by Fischer in the Pare Mountains. In 1903, Reichenow assigned both species to his newly erected genus ''Pseudonigrita'', because he considered ''P. arnaudi'' and ''P. cabanisi'' related to weaverbirds (Ploceidae), while the other species '' Nigrita bicolor'', '' N. canicapillus'', '' N. fusconota'' and '' N. luteifrons'' are negrofinches assigned to the estrildid finche ...

Grey-capped Social Weaver
The grey-capped social weaver (''Pseudonigrita arnaudi'') is a sparrow-like liver-colored bird, with a pale grey crown, a dark grey bill, a whitish eye-ring, horn-colored legs, with some black in the wing and a light terminal band in the tail, that builds roofed nests made of straws, breeds in colonies in thorny Acacia trees, and feeds in groups gathering grass seeds and insects. Male and female have near identical plumage. DNA profiling, DNA-analysis confirms it is part of the Ploceidae, weaver family. It is found in Ethiopia, Kenya, Somalia, South Sudan, Sudan, Tanzania, and Uganda. Taxonomy The French naturalist Charles Lucien Bonaparte described the grey-capped social weaver as ''Nigrita arnaudi'' in 1850. He chose the specific epithet to honor Joseph Pons d'Arnaud, the French explorer who had collected a specimen around 1841 near Juba on the White Nile, and sent it to the National Museum of Natural History (France), French Museum of Natural History. In 1903, the German zool ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black-capped Social Weaver
The black-capped social weaver (''Pseudonigrita cabanisi'') is a sparrow-like species of bird that has been assigned to the weaverbird family. It was originally described by Fisher and Reichenow, and later re-classified by the latter to the genus ''Pseudonigrita''. Adults have a large black cap, ivory-colored bill, red eyes, brown back and wings, blackish-brown tail, white throat and underparts with a black midline, and dark horn-colored legs. It breeds in colonies and roofed nests with an entrance at the bottom in thorny trees such as acacias are constructed by the male from grass stems. It is found in parts of Ethiopia, Kenya, Somalia, and Tanzania. It is sometimes kept and bred in captivity. Taxonomy and systematics In 1884, the black-capped social weaver was first described by German East-Africa explorer Gustav Fischer and German ornithologist Anton Reichenow as ''Nigrita cabanisi'', based on a specimen collected in 1883 by Fischer in the Pare Mountains.

Ploceidae
Ploceidae is a family of small passerine birds, many of which are called weavers, weaverbirds, weaver finches, or bishops. These names come from the nests of intricately woven vegetation created by birds in this family. In most recent classifications, the Ploceidae are a clade that excludes some birds that have historically been placed in the family, such as some of the Old World sparrow, 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 species, introduced outside their native range. Taxonomy and systematics The family Ploceidae was introduced (as Ploceïdes) by Swedish zoologist Carl Jakob Sundevall in 1836. Phylogenetic studies have shown that the family is sister taxon, sister to a clade containing the families Viduidae and Estr ...

Philetairus Socius
The sociable weaver (''Philetairus socius'') is a species of bird in the weaver family, endemic to Southern Africa. It is the only species in its genus ''Philetairus''. It is found in South Africa, Namibia, and Botswana, but its range is centered within the Northern Cape Province of South Africa. The species builds large, compound, community nests, a rarity among birds. These nests are perhaps the most spectacular structure built by any bird. Taxonomy and systematics The sociable weaver was first described by ornithologist John Latham in 1790. Alternative names include the common social weaver, common social-weaver, and social weaver. Formerly, four subspecies were recognised, but the species is now considered monotypic. The sociable weaver is the only extant species in the genus ''Philetairus''. Phylogeny Based on a 2017 DNA-analysis, ''P. socius'' belongs to the group of sparrow weavers (subfamily Plocepasserinae) and is most related to the genus ''Pseudonigrita''. The ...

Plocepasser
The sparrow-weavers (''Plocepasser'') are a genus of birds in the family (biology), 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 group, sister to the most basic genus of the subfamily, ''Sporopipes''. Provided that genera are correct clades, the following tree expresses current insights.

Joseph Pons D'Arnaud
Théodore Louis Joseph-Pons d'Arnaud (1811-1884) was a French civil engineer, geographer and naturalist. In 1830 he was hired by the government of Egypt to work on irrigation projects. In 1840-41 he participated in an expedition raised by the Pasha of Egypt that searched (unsuccessfully) for the source of the White Nile. In 1841-42 he explored in the Sudan on an expedition led by Binbashi (Major) Selim, a Turkish officer in the Marine d'Alexandrie. Further voyages of exploration took him to Ethiopia and Yemen (1843) and the Sudan (1860). In 1844 d'Arnaud was awarded the Grande Médaille d'Or des Explorations (gold medal for exploration) by French Geographical Society. In 1856 he was appointed as a Lieutenant colonel in an Egyptian regiment. D'Arnaud authored a book on the aquatic plants of the Upper Nile. Two bird species are named in his honour: D'Arnaud's barbet, an East African insectivorous bird, and the Grey-capped social weaver The grey-capped social weaver (''Pseudoni ...

Amblyospiza Albifrons
The thick-billed weaver (''Amblyospiza albifrons''), or grosbeak weaver, is a distinctive and bold species of weaver bird that is native to the Afrotropics. It belongs to the monotypic genus ''Amblyospiza'' and subfamily Amblyospizinae. They have particularly strong mandibles, which are employed to extricate the seeds in nutlets and drupes, and their songs are comparatively unmusical and harsh. Their colonial nests are readily distinguishable from those of other weavers, due to their form and placement, and the fine strands used in their construction. They habitually fan and flick their tails. Taxonomy and systematics The generic name ''Amblyospiza'' was coined by Carl Jakob Sundevall in 1850 and means "blunt, finch", referencing the very large bill, while the specific name ''albifrons'' refers white forehead of the males. The thick-billed weaver was formally described as ''Pyrrhula albifrons'' in 1831 by the Irish zoologist and politician Nicholas Aylward Vigors from the coll ...

Sister Group
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxono ...

Anton Reichenow
Anton Reichenow (1 August 1847 in Charlottenburg – 6 July 1941 in Hamburg) was a German ornithologist and Herpetology, herpetologist. Reichenow was the son-in-law of Jean Cabanis, and worked at the Natural History Museum, Berlin, 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.
