Cardinal Quelea
The cardinal quelea (''Quelea cardinalis'') is a species of bird in the family Ploceidae. It is found in Burundi, Democratic Republic of the Congo, Ethiopia, Kenya, Malawi, Rwanda, South Sudan, Tanzania, Uganda, and Zambia. Description The cardinal quelea is a small (about long) sparrow-like bird with a short heavy black bill, that breeds in colonies. The male in breeding plumage has a red head extending onto the breast but not onto the streaked nape. The female has a yellowish face, brow stripes and throat. The non-breeding plumage of the male resembles that of the female, but retains some red on its head. Taxonomy Gustav Hartlaub was the first to describe the cardinal quelea, giving it the scientific name ''Hyphantica cardinalis'' in 1880, based on specimens that were collected by Emin Pasha near Lado in South-Sudan during 1879. In 1951, Hans von Boetticher regarded the cardinal quelea and red-headed quelea sufficiently different from the red-billed quelea to create a n ...

Gustav Hartlaub
Karel Johan Gustav Hartlaub (8 November 1814 – 29 November 1900) was a German physician and ornithologist. Hartlaub was born in Bremen, and studied at Bonn and Berlin before graduating in medicine at Göttingen. In 1840, he began to study and collect exotic birds, which he donated to the Bremen Natural History Museum. He described some of these species for the first time. In 1852, he set up a new journal with Jean Cabanis, the ''Journal für Ornithologie''. He wrote with Otto Finsch, ''Beitrag zur Fauna Centralpolynesiens: Ornithologie der Viti-, Samoa und Tonga- Inseln''. Halle, H. Schmidt. This 1867 work which has handcoloured lithographs was based on bird specimens collected by Eduard Heinrich Graeffe for Museum Godeffroy. A number of birds were named for him, including Hartlaub's Bustard, Hartlaub's Turaco, Hartlaub's Duck, and Hartlaub's Gull Hartlaub's gull (''Chroicocephalus hartlaubii''), also known as the king gull, it is a small gull. It was formerly sometimes cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swahili Language
Swahili, also known by its local name , is the native language of the Swahili people, who are found primarily in Tanzania, Kenya and Mozambique (along the East African coast and adjacent litoral islands). It is a Bantu language, though Swahili has borrowed a number of words from foreign languages, particularly Arabic, but also words from Portuguese, English and German. Around forty percent of Swahili vocabulary consists of Arabic loanwords, including the name of the language ( , a plural adjectival form of an Arabic word meaning 'of the coast'). The loanwords date from the era of contact between Arab slave traders and the Bantu inhabitants of the east coast of Africa, which was also the time period when Swahili emerged as a lingua franca in the region. The number of Swahili speakers, be they native or second-language speakers, is estimated to be approximately 200 million. Due to concerted efforts by the government of Tanzania, Swahili is one of three official languages (th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of East Africa
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-headed Quelea
The red-headed quelea (''Quelea erythrops'') is a species of bird in the family Ploceidae. It is found in Angola, Benin, Botswana, Burkina Faso, Burundi, Cameroon, Central African Republic, Chad, Republic of the Congo, Democratic Republic of the Congo, Ivory Coast, Equatorial Guinea, Eswatini, Ethiopia, Gabon, Gambia, Ghana, Guinea, Guinea-Bissau, Kenya, Liberia, Malawi, Mali, Mozambique, Niger, Nigeria, Rwanda, São Tomé and Príncipe, Senegal, Sierra Leone, South Africa, South Sudan, Tanzania, Togo, Uganda, Zambia, and Zimbabwe. Taxonomy and naming The red-headed quelea was collected by Carl Weiss on Sao Tome island in 1847, and after its arrival at the Hamburg Museum described for science for the first time by Gustav Hartlaub in 1848, who named it ''Ploceus erythrops''. In 1951, Hans von Boetticher regarded the cardinal quelea and red-headed quelea sufficiently different from the red-billed quelea to create a new genus ''Queleopsis''. The species epithet ''ery ...

Red-billed Quelea
The red-billed quelea (; ''Quelea quelea''), also known as the red-billed weaver or red-billed dioch, is a small—approximately long and weighing —migratory, sparrow-like bird of the weaver family, Ploceidae, native to Sub-Saharan Africa. It was named by Linnaeus in 1758, who considered it a bunting, but Ludwig Reichenbach assigned it in 1850 to the new genus ''Quelea''. Three subspecies are recognised, with ''Quelea quelea quelea'' occurring roughly from Senegal to Chad, ''Q. q. aethiopica'' from Sudan to Somalia and Tanzania, and ''Q. q. lathamii'' from Gabon to Mozambique and South Africa. Non-breeding birds have light underparts, striped brown upper parts, yellow-edged flight feathers and a reddish bill. Breeding females attain a yellowish bill. Breeding males have a black (or rarely white) facial mask, surrounded by a purplish, pinkish, rusty or yellowish wash on the head and breast. The species avoids forests, deserts and colder areas such as those ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quelea
''Quelea'' is a genus of small passerine birds that belongs to the weaver family Ploceidae, confined to Africa. These are small-sized, sparrow- or finch-like gregarious birds, with bills adapted to eating seeds. Queleas may be nomadic over vast ranges; the red-billed quelea is said to be the most numerous bird species in the world. Taxonomy There are three species: Phylogeny Based on recent DNA-analysis, the red-billed quelea is sister to a clade that consist of both remaining species of the genus ''Quelea'', namely ''Q. cardinalis'' and ''Q. erythrops''. The genus belongs to the group of true weavers (subfamily Ploceinae), and is most related to '' Foudia'', a genus of six or seven species that occur on the islands of the western Indian Ocean. This clade is sister to the Asian species of the genus ''Ploceus ''Ploceus'' is a genus of birds in the weaver family, Ploceidae. They are native to the Indomalayan and Afrotropical realms.

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. ...

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 taxonomic ...

DNA Phenotyping
DNA phenotyping (''noing'') is the process of predicting an organism's phenotype using only genetic information collected from genotyping or DNA sequencing. This term, also known as molecular photofitting, is primarily used to refer to the prediction of a person's physical appearance and/or biogeographic ancestry for forensic purposes. DNA phenotyping uses many of the same scientific methods as those being used for genetically-informed personalized medicine, in which drug responsiveness (pharmacogenomics) and medical outcomes are predicted from a patient's genetic information. Significant genetic variants associated with a particular trait are discovered using a genome-wide association study (GWAS) approach, in which hundreds of thousands or millions of single-nucleotide polymorphisms (SNPs) are tested for their association with each trait of interest. Predictive modeling is then used to build a mathematical model for making trait predictions about new subjects. Predicted pheno ...
