Yellow-fronted Parrot
The yellow-fronted parrot (''Poicephalus flavifrons'') is a parrot endemic to the Ethiopian Highlands. It is a mostly green with a yellow head. Relatively little is known about this bird. Taxonomy German naturalist Eduard Rüppell first described the yellow-fronted parrot in 1845. Its species name is derived from the Latin words ''flavus'' "yellow", and ''frons'' "forehead". It is also known as the yellow-faced parrot. Most recent authorities treat it as monotypic, but some recognized two slightly different subspecies, ''P. f. flavifrons'' and ''P. f. aurantiiceps''.Forshaw (2006). plate 67. Description The yellow-fronted parrot is about long and is mostly green with the upper parts being a darker green, the tail being olive-brown, and the legs a dark grey-brown. The face is orange-yellow. When two subspecies are recognized, the nominate is believed to have yellow to its head and face, while in ''P. f. aurantiiceps'' some of the yellow is replaced with orange. The upper b ...

Eduard Rüppell
Wilhelm Peter Eduard Simon Rüppell (20 November 1794 – 10 December 1884) was a German Natural history, naturalist and List of explorers, explorer. Rüppell is occasionally transliterated to "Rueppell" for the English alphabet, due to german orthography. Biography Rüppell was born in Frankfurt am Main, the son of a prosperous banker, who was a partner in 'Rüppell und Harnier’s Bank'. He was originally destined to be a merchant, but after a visit to Sinai Peninsula, Sinai in 1817, where he met Henry Salt (Egyptologist), Henry Salt and the Swiss-German traveller Johann Ludwig Burckhardt, Ludwig Burckhardt. He explored Giza and the Pyramids with Salt. In 1818, he developed an interest in natural history, and became elected member of the ''Senckenbergische Naturforschende Gesellschaf''. He attended lectures at the University of Pavia and University of Genoa in botany and zoology. Rüppell set off on his first expedition in 1821, accompanied by surgeon Michael Hey as his assistan ...

Cere
The beak, bill, or rostrum is an external anatomical structure found mostly in birds, but also in turtles, non-avian dinosaurs and a few mammals. A beak is used for eating, preening, manipulating objects, killing prey, fighting, probing for food, Courtship#Courtship in the animal kingdom, courtship, and feeding young. The terms ''beak'' and ''Rostrum (anatomy), rostrum'' are also used to refer to a similar mouth part in some ornithischians, pterosaurs, cetaceans, dicynodonts, anuran tadpoles, monotremes (i.e. echidnas and platypuses, which have a beak-like structure), Sirenidae, sirens, Tetraodontidae, pufferfish, billfishes and Cephalopod beak, cephalopods. Although beaks vary significantly in size, shape, color and texture, they share a similar underlying structure. Two bony projections – the upper and lower mandibles – are covered with a thin keratinized layer of epidermis known as the rhamphotheca. In most species, two holes called ''nares'' lead to the respiratory system. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Birds Of Ethiopia
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poicephalus
The genus ''Poicephalus'' belongs to the subfamily Psittacinae of the true parrots (Psittacidae) and comprises ten species of parrots native to various regions of the Afrotropical realm, which encompasses Sub-Saharan Africa, ranging from Senegal in the west, Ethiopia in the east, and to South Africa in the south. Like lovebirds ('' Agapornis'') and vasa parrots ('' Coracopsis''), the latter being endemic to Madagascar, the ''Poicephalus'' parrots are typical specimens of Afrotropical zoogeography. Several of the species exist in slightly different forms, or subspecies. ''Poicephalus'' parrots have been kept as pets and companion birds for centuries, the Senegal parrot perhaps being the most famous species. The trade in this species most likely began in the early 19th century, when Senegal parrots first appeared as companion birds in Europe. Alongside African grey parrots, Senegal parrots still range among the mostly frequently imported parrots from Africa. Appearance Mem ...

Princeton University Press
Princeton University Press is an independent publisher with close connections to Princeton University. Its mission is to disseminate scholarship within academia and society at large. The press was founded by Whitney Darrow, with the financial support of Charles Scribner, as a printing press to serve the Princeton community in 1905. Its distinctive building was constructed in 1911 on William Street in Princeton. Its first book was a new 1912 edition of John Witherspoon's ''Lectures on Moral Philosophy.'' History Princeton University Press was founded in 1905 by a recent Princeton graduate, Whitney Darrow, with financial support from another Princetonian, Charles Scribner II. Darrow and Scribner purchased the equipment and assumed the operations of two already existing local publishers, that of the ''Princeton Alumni Weekly'' and the Princeton Press. The new press printed both local newspapers, university documents, ''The Daily Princetonian'', and later added book publishing to it ...

Red-fronted Parrot
The red-fronted parrot (''Poicephalus gulielmi''), also known as Jardine's parrot, is a medium-sized mainly green parrot distributed across wide areas of Africa. It has three subspecies. The extent and shade of the red or orange plumage on its head, thighs, and bend of wings vary depending on the subspecies. They are popular as pets, partly because of their ability to mimic speech and copy sounds. Trapping of wild birds for the pet trade is a potential threat to wild populations; however, they are protected by CITES (appendix II) making the trade, import and export of all wild-caught parrots illegal. Description The red-fronted parrot is 28 cm (11 in) long. It is mostly green and has a short black squarish tail. Black feathers on the head, neck, back, and wings have lighter green edges giving a scalloped appearance. The lower mandible is dark grey and the upper mandible has a horn coloured base and a dark grey tip. The irises are red-orange, the eyerings are pi ...

Cape Parrot
The Cape parrot (''Poicephalus robustus'') or Levaillant's parrot is a large, temperate forest dwelling parrot of the genus ''Poicephalus'' endemic to South Africa. It was formerly grouped as a subspecies along with the savanna-dwelling brown-necked parrot (''Poicephalus fuscicollis'') and grey-headed parrot (''P. f. suahelicus''), but is now considered a distinct species. Taxonomy The Cape parrot was described in 1781 by the English ornithologist John Latham under the English name, the "robust parrot". When in 1788 the German naturalist Johann Friedrich Gmelin revised and expanded Carl Linnaeus's ''Systema Naturae'', he included the Cape parrot with a short description, coined the binomial name ''Psittacus robustus'' and cited Latham's work. The type locality is South Africa. The Cape parrot is now placed with nine other species in the genus ''Poicephalus'' that was introduced by the English naturalist William John Swainson in 1837. The genus name is from the Ancient Greek ''p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Tana
Lake Tana ( am, ጣና ሐይቅ, T’ana ḥāyik’i; previously Tsana) is the largest lake in Ethiopia and the source of the Blue Nile. Located in Amhara Region in the north-western Ethiopian Highlands, the lake is approximately long and wide, with a maximum depth of , and an elevation of . Lake Tana is fed by the Gilgel Abay, Reb and Gumara rivers. Its surface area ranges from , depending on season and rainfall. The lake level has been regulated since the construction of the control weir where the lake discharges into the Blue Nile. This controls the flow to the Blue Nile Falls (Tis Abbai) and hydro-power station. In 2015, the Lake Tana region was nominated as a UNESCO Biosphere Reserve recognizing its national and international natural and cultural importance. Overview Lake Tana was formed by volcanic activity, blocking the course of inflowing rivers in the early Pleistocene epoch, about 5 million years ago. The lake was originally much larger than it is today. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (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 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 ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
