Green White-eye
The green white-eye (''Zosterops stuhlmanni'') is a bird species in the family Zosteropidae. It is found in Tanzania, Uganda and the Democratic Republic of the Congo. The green white-eye was formerly treated as a subspecies of the African yellow white-eye (since renamed the northern yellow white-eye) (''Zosterops senegalensis''). It is now considered as a separate species based in part on the phylogenetic relationships determined in a 2013 molecular study. Four subspecies are recognised: * ''Z. s. stuhlmanni'' Reichenow, 1892 – northwest Tanzania, south and central Uganda * ''Z. s. reichenowi'' Dubois, AJC, 1911 – east D.R. Congo * ''Z. s. toroensis'' Reichenow, 1904 – northeast D.R. Congo and west Uganda * ''Z. s. scotti'' Neumann, 1899 – southwest Uganda: Bwindi Impenetrable National Park and above in the Virunga Mountains The Virunga Mountains (also known as Mufumbiro) are a chain of volcanoes in East Africa, in the area where Rwanda, the Democratic Republ ...

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. Reichenow is known for his classification of birds into six groups, described, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
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. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists 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. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zosteropidae
The white-eyes are a family, Zosteropidae, of small passerine birds native to tropical, subtropical and temperate Sub-Saharan Africa, southern and eastern Asia, and Australasia. White-eyes inhabit most tropical islands in the Indian Ocean, the western Pacific Ocean, and the Gulf of Guinea. Discounting some widespread members of the genus '' Zosterops'', most species are endemic to single islands or archipelagos. The silvereye, ''Zosterops lateralis'', naturally colonised New Zealand, where it is known as the "wax-eye" or ''tauhou'' ("stranger"), from 1855. The silvereye has also been introduced to the Society Islands in French Polynesia, while the Japanese white-eye has been introduced to Hawaii. Characteristics White-eyes are mostly of undistinguished appearance, the plumage being generally greenish olive above, and pale grey below. Some species have a white or bright yellow throat, breast, or lower parts, and several have buff flanks. As their common name implies, many sp ...

Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...

Northern Yellow White-eye
The northern yellow white-eye (''Zosterops senegalensis''), formerly the African yellow white-eye, is a species of bird in the family Zosteropidae. It is found across sub-Saharan Africa, from Senegal in the west across to southern Sudan in the east and south to northern Angola. It was formerly considered to be conspecific with the Angola white-eye. Taxonomy The northern yellow white-eye formerly included additional subspecies. These were split to create the southern yellow white-eye and the green white-eye based partly on the results of a molecular phylogenic study in 2013. Four subspecies are recognised: * ''Z. s. senegalensis'' Bonaparte, 1850 – Mauritania and Senegal to northwest Ethiopia * ''Z. s. jacksoni'' Neumann, 1899 – west Kenya and north Tanzania * ''Z. s. demeryi'' Büttikofer, 1890 – Sierra Leone, Liberia and Ivory Coast * ''Z. s. gerhardi'' Elzen & König, C, 1983 – south Sudan and northeast Uganda Description A small yellow bird with a prominent white e ...

Phylogenetic
In biology, phylogenetics () is the study of the evolutionary history of life using observable characteristics of organisms (or genes), which is known as phylogenetic inference. It infers the relationship among organisms based on empirical data and observed heritable traits of DNA sequences, protein amino acid sequences, and morphology. The results are a phylogenetic tree—a diagram depicting the hypothetical relationships among the organisms, reflecting their inferred evolutionary history. The tips of a phylogenetic tree represent the observed entities, which can be living taxa or fossils. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the taxa represented on the tree. An unrooted tree diagram (a network) makes no assumption about directionality of character state transformation, and does not show the origin or "root" of the taxa in question. In addition to their use for inferring phylogenetic pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alphonse Joseph Charles Dubois
Alphonse Joseph Charles Dubois (18 October 1839 at Aix-la-Chapelle – 1 June 1921 at Koksijde, Coxyde-sur-Mer) was a Belgian naturalist. He took a doctorate in medicine, and in 1869 became curator of the department of vertebrates at the Royal Belgian Institute of Natural Sciences, Royal Museum of Natural History in Brussels. He worked with his father, Charles Frédéric Dubois (1804–1867), in the production of ''Les Oiseaux de l’Europe et leurs œufs'', completing it after his father’s death. The book was in two volumes, the second consisting of illustrations by Dubois senior. He produced the two-volume ''La Faune illustrée des Vertébrés de la Belgique''.

Oscar Neumann
Oscar Rudolph Neumann (3 September 1867 in Berlin – 17 May 1946 in Chicago) was a German ornithology, ornithologist and naturalist who explored and collected specimens in Africa. He fled via Cuba and settled in the United States to escape Nazi persecution of Jews. Neumann's starling (''Onychognathus neumanni'') and several other species are named after him. Neumann was born in wealthy Jewish family, the son of Maximilian and Anna née Meyer. A younger sister of his was Elsa Neumann (1872-1902) who became one of the first physics doctorates from Berlin University. Another sister Alice was a sculptor. He travelled to German East Africa across Tanganyika, Uganda and Kenya in 1892 and collected for the Berlin Museum publishing descriptions. In 1899 he accompanied Baron Carlo von Erlanger through Somaliland and southern Ethiopia, collecting birds that went to Lord Walter Rothschild, 2nd Baron Rothschild, Walter Rothschild's bird collection in Tring. In 1915 he went to New Guinea a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bwindi Impenetrable National Park
The Bwindi Impenetrable National Park is a national park in southwestern Uganda. It is part of the Bwindi Impenetrable Forest and is situated along the Democratic Republic of the Congo border next to the Virunga National Park and on the edge of the Albertine Rift. Composed of of both lowland and montane forest, it is accessible only on foot. It is a United Nations Educational, Scientific and Cultural Organization-designated World Heritage Site. Species diversity is a feature of the park. It provides habitat for 120 species of mammals, 350 species of birds, 310 species of butterflies, 27 species of frogs, chameleons, geckos, and many endangered species. Floristically, the park is among the most diverse forests in East Africa, with more than 1,000 flowering plant species, including 200 species of trees and 104 species of ferns. The northern (low elevation) sector has many species of Guineo-Congolian flora, including two endangered species, the brown mahogany and '' Brazzeia longi ...

Virunga Mountains
The Virunga Mountains (also known as Mufumbiro) are a chain of volcanoes in East Africa, in the area where Rwanda, the Democratic Republic of the Congo (DRC), and Uganda meet. The mountain range is a branch of the Albertine Rift Mountains, which border the western branch of the East African Rift. They are located between Lake Edward and Lake Kivu. The name "Virunga" is an English version of the Kinyarwanda word ''ibirunga'', which means "volcanoes". The mountain range consists of eight major volcanoes. Most of them are dormant, except Mount Nyiragongo and Mount Nyamuragira , both in the DRC. Recent eruptions occurred in 2006, 2010 and May 2021. Mount Karisimbi is the highest volcano at . The oldest mountain is Mount Sabyinyo, which rises above sea level. The Virunga Mountains are home of the endangered mountain gorilla, listed on the IUCN Red List of Endangered Species due to habitat loss, poaching, disease, and war (Butynski et al. 2003).

Zosterops
''Zosterops'' (meaning "eye-Zoster (costume), girdle") is a genus of passerine birds containing the typical white-eyes in the white-eye family Zosteropidae. The genus has the largest number of species in the white-eye family. They occur in the Afrotropical realm, Afrotropical, Indomalayan realm, Indomalayan, and Australasian realms. Typical white-eyes have a length of between . Their most characteristic feature is a conspicuous white feather eye-ring, ring around the eye, though some species lack it. The species in this group vary in the structural adaptations of the tongue. The ''Zosterops'' [''griseotinctus''] group is an example of a "great speciator" inhabiting a vast area and showing a remarkable morphological differentiation on islands, some of which may be as close as apart. Systematics The genus ''Zosterops'' was introduced by the naturalists Nicholas Aylward Vigors, Nicholas Vigors and Thomas Horsfield in 1827. The name combines the Ancient Greek words ''zōstēros'' "b ... [...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 common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings 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 furt ...
