Lemon-breasted Canary
The lemon-breasted canary (''Crithagra citrinipectus''), also known as the lemon-breasted seedeater, is a species of finch in the family Fringillidae. It is found in Malawi, Mozambique, South Africa, Zambia, and Zimbabwe. Its natural habitats are dry savannah, subtropical or tropical dry shrubland, and rural gardens. Taxonomy and systematics The lemon-breasted canary was identified as species in 1960 by Clancey and Lawson from a type obtained near Panda, in Inhambane Province of southern Mozambique. Research involving mitochondrial DNA analysis suggests that this species along with ''Crithagra leucopygius, S. leucopygia'', ''Serinus mozambicus, S. mozambicus'', and ''Serinus dorsostriatus, S. dorsostriatus'' belong in a separate genus, ''Ochrospiza'', as they have been revealed to be only distantly related to other African members of the present genus, ''Serinus''. However, before a revision can be made, a detailed inspection of all the taxa in the current genus is necessary. Some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phillip Clancey
Phillip Alexander Clancey (26 September 1917 – 18 July 2001) was a leading authority on the ornithology of South Africa. Background and education Phillip Clancey was born, brought up and educated in Glasgow, Scotland. He studied at the Glasgow School of Art where his artistic skills were developed. Military service Clancey served in the 51st (Highland) Division with the Allied forces in Sicily and Italy during World War II, narrowly escaping death and being deafened in one ear by an artillery explosion. Following his death in 2001, Clancey's military medals, together with his "Gill Memorial Medal" were auctioned by City Coins, Cape Town, in 2006, on behalf of the Clancey Estate. These medals, including the Gill Memorial Medal were purchased on the auction by David R. Bennett - Chairman of the Durban Natural Science Museum Trust, and the medals now form part of the Bennett Military Medal Collection. Clancey's group of six military medals are to (Service Number) 913613 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serinus Mozambicus
The yellow-fronted canary (''Crithagra mozambica'') is a small passerine bird in the finch family. It is sometimes known in aviculture as the green singing finch. The yellow-fronted canary was formerly placed in the genus ''Serinus'', but phylogenetic analysis using mitochondrial and nuclear DNA sequences found that genus to be polyphyletic. The genus was therefore split and a number of species including the yellow-fronted canary were moved to the resurrected genus ''Crithagra'' Swainson 1827. This bird is a resident breeder in Africa south of the Sahara Desert. Its habitat is open woodland and cultivation. It nests in trees, laying three or four eggs in a compact cup nest. It has been introduced to the Hawaiian Islands, where it is found on western Hawaii, southeastern Oahu and Molokai. The yellow-fronted canary is a common, gregarious seedeater. It is 11–13 cm in length. The adult male has a green back and brown wings and tail. The underparts and rump are yellow, and ...

Birds Described In 1960
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] |

Crithagra Citrinipectus, Ponto Da Barra, Birding Weto, A
''Crithagra'' is a genus of small passerine birds in the finch family (Fringillidae). They live in Africa and Arabia. The species in this genus were formerly assigned to the genus ''Serinus'', but phylogenetic analysis of mitochondrial and nuclear DNA sequences found that the genus was polyphyletic. It was therefore split into two monophyletic genera. Eight species, including the European serin (''Serinus serinus''), were retained in ''Serinus'', while the other species were assigned to the resurrected genus ''Crithagra''. The genus was introduced in 1827 by the English ornithologist William John Swainson. The type species was subsequently designated as the brimstone canary. The name comes from the classical Greek ''krithē'' for "barley" and ''agra'' for "hunting". The genus contains 37 species: *Príncipe seedeater, ''Crithagra rufobrunnea'' *São Tomé grosbeak, ''Crithagra concolor'' * African citril, ''Crithagra citrinelloides'' *Western citril, ''Crithagra frontalis'' *Sou ...

Polyphyletic
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with systema ...

Mitochondrial
A mitochondrion (; ) is an organelle found in the cells of most Eukaryotes, such as animals, plants and fungi. Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate (ATP), which is used throughout the cell as a source of chemical energy. They were discovered by Albert von Kölliker in 1857 in the voluntary muscles of insects. The term ''mitochondrion'' was coined by Carl Benda in 1898. The mitochondrion is popularly nicknamed the "powerhouse of the cell", a phrase coined by Philip Siekevitz in a 1957 article of the same name. Some cells in some multicellular organisms lack mitochondria (for example, mature mammalian red blood cells). A large number of unicellular organisms, such as microsporidia, parabasalids and diplomonads, have reduced or transformed their mitochondria into other structures. One eukaryote, ''Monocercomonoides'', is known to have completely lost its mitochondria, and one multicellular organism, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serinus
''Serinus'' is a genus of small birds in the finch family Fringillidae found in Europe and Africa. The birds usually have some yellow in their plumage. The genus was introduced in 1816 by the German naturalist Carl Ludwig Koch. Its name is New Latin for "canary-yellow". Many species were at one time assigned to the genus but it became clear from phylogenetic studies of mitochondrial and nuclear DNA sequences that the genus was polyphyletic. This was confirmed by Dario Zuccon and coworkers in a comprehensive study of the finch family published in 2012. The authors suggested splitting the genus into two monophyletic groups, a proposal that was accepted by the International Ornithologists' Union. The genus ''Serinus'' was restricted to the European serin and seven other species while a larger clade from Africa and Arabia was assigned to the resurrected genus ''Crithagra ''Crithagra'' is a genus of small passerine birds in the finch family (Fringillidae).

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Serinus Atrogularis
The black-throated canary (''Crithagra atrogularis''), also known as the black-throated seedeater, is a species of finch in the family Fringillidae. Distribution It is found frequently in Angola, Botswana, Burundi, Republic of the Congo, Democratic Republic of the Congo, Gabon, Kenya, Lesotho, Namibia, Rwanda, South Africa, Tanzania, Uganda, Zambia, and Zimbabwe. Its natural habitats are subtropical or tropical dry forest, dry savanna, and subtropical or tropical dry shrubland. Taxonomy The black-throated canary was formerly placed in the genus ''Serinus'' but phylogenetic analysis using mitochondrial and nuclear DNA sequences found that the genus was polyphyletic.
