Plocepasser Donaldsoni -Samburu National Reserve, Kenya-8
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 to the most basic genus of the subfamily, ''Sporopipes ''Sporopipes'' is a genus of bird Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a h ...''. Provided that genera are correct clades, the following tree expresses current insights. Referenc ...

White-browed Sparrow-weaver
The white-browed sparrow-weaver (''Plocepasser mahali'') is a predominantly brown, Old World sparrow, sparrow-sized bird found throughout central and north-central southern Africa. It is found in groups of two to eleven individuals consisting of one breeding pair and other non-reproductive individuals. Taxonomy and systematics During his expedition to the interior of southern Africa in 1834–35, Andrew Smith (zoologist), Andrew Smith collected specimens of the white-browed sparrow weaver at the Modder River, which he described in 1836, giving it the Binomial nomenclature, scientific name ''Plocepasser mahali''. Etymology Smith did not provide an explanation for the species epithet ''mahali'', but is clear it is not a Latin name. Probably it is derived from the vernacular name for the bird in Tswana language, Setswana ''mogale'' or from the Sotho language, Sesotho word ''mohale'', a brave or fierce person, which suggests the bird's name may refer to its angry scolding.

Dinemellia Dinemelli
The white-headed buffalo weaver or white-faced buffalo-weaver (''Dinemellia dinemelli'') is a species of passerine bird in the family Ploceidae native to East Africa. The buffalo part of its name derives from its habit of following the African buffalo, feeding on disturbed insects. Two subspecies are recognized. Taxonomy The white-headed buffalo weaver was first described by the German naturalist Eduard Rüppell in 1845. Subspecies Two subspecies of the white-headed buffalo weaver are now recognized. Description The white-headed buffalo weaver is in length and in weight. In addition to its white head and underparts, the white-headed buffalo weaver has a vividly orange-red rump and undertail coverts. Its thighs are dark brown. Narrow white bands can be found on the wings especially when stretch his wings sideways. Both sexes are similar in plumage and hard to differentiate. The bill is conical and black. ''D. d. dinemelli'' has a brown tail, whereas ''D. d. boehmi'' has a bla ...

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 ...

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 ...

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 ...

Andrew Smith (zoologist)
Sir Andrew Smith (3 December 1797 – 11 August 1872) was a British surgery, surgeon, explorer, ethnologist and zoology, zoologist. He is considered the father of zoology in South Africa having described many species across a wide range of groups in his major work, ''Illustrations of the Zoology of South Africa''. Smith was born in Hawick, Roxburghshire. He qualified in medicine at the University of Edinburgh obtaining an Doctor of Medicine, M.D. degree in 1819, having joined the Army Medical Services in 1816. South Africa 1820–1837 In 1820 he was ordered to the Cape Colony and was sent to Grahamstown to supervise the medical care of European soldiers and soldiers of the Cape Corps. He was appointed the Albany district surgeon in 1822 and started the first free dispensary for indigent patients in South Africa. He led a scientific expedition into the interior and was able to indulge in his interests of natural history and anthropology. On several occasions, he was sent by gov ...
