Verreaux's Eagle
Verreaux's eagle (''Aquila verreauxii'') is a large, mostly African, bird of prey. It is also called the black eagle, especially in southern Africa, not to be confused with the black eagle (''Ictinaetus malayensis'') of south and southeast Asia. The Verreaux's eagle lives in hilly and mountainous regions of southern and eastern Africa (extending marginally into Chad, Mali and Niger), and very locally in the Middle East. Verreaux's eagle is one of the most specialized species of accipitrid in the world, with its distribution and life history revolving around its favorite prey species, the rock hyraxes. When hyrax populations decline, the species have been shown to survive with mixed success on other prey, such as small antelopes, Galliformes, gamebirds, hares, monkeys and other assorted vertebrates. Despite a high degree of specialization, Verreaux's eagle has, from a conservation standpoint, been faring relatively well in historic times. One population of this species, in the Mat ...

Walter Sisulu National Botanical Garden
__NOTOC__ The Walter Sisulu National Botanical Garden, previously known as the Witwatersrand National Botanical Garden, is a botanical reserve in western Roodepoort, near Johannesburg, South Africa. History The garden was formally established in 1982 as the Transvaal National Botanic Gardens, at which time it was the 14th of South Africa's National Botanical Gardens. It was opened to the public in 1987 as the Witwatersrand National Botanical Gardens, on the occasion of the handing over of some 120 ha of farm Roodekrans by the Krugersdorp Town Council for inclusion in the reserve. Though one of the youngest of South Africa's National Botanical Gardens, the site has been popular with visitors for many decades before its proclamation. The garden has a restaurant, gift shop and bird hide overlooking a small dam. Up to March 2015 it operated a nursery which cultivated native South African plants. The Garden has been recognised as one of the most beautiful botanical garden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monkey
Monkey is a common name that may refer to most mammals of the infraorder Simiiformes, also known as simians. Traditionally, all animals in the group now known as simians are counted as monkeys except the apes. Thus monkeys, in that sense, constitute an incomplete paraphyletic grouping; alternatively, if apes (Hominoidea) are included, ''monkeys'' and ''simians'' are synonyms. In 1812, Étienne Geoffroy grouped the apes and the Cercopithecidae group of monkeys together and established the name Catarrhini, "Old World monkeys" ("''singes de l'Ancien Monde''" in French). The extant sister of the Catarrhini in the monkey ("singes") group is the Platyrrhini (New World monkeys). Some nine million years before the divergence between the Cercopithecidae and the apes, the Platyrrhini emerged within "monkeys" by migration to South America likely by ocean. Apes are thus deep in the tree of extant and extinct monkeys, and any of the apes is distinctly closer related to the Cercopith ...

Booted Eagles
Booted eagles are eagles that have fully feathered tarsi. That is, their legs are covered with feathers down to the feet. Most other accipitrids have bare lower legs, scaled rather than feathered. They may be treated as an informal group, as distinct from "fish eagles" (or "sea eagles"), "snake eagles", and "giant forest eagles". They may also be treated as a formal taxon, either as a tribe (Aquililae) or subfamily ( Aquilinae). The booted eagles, sea eagles, harpy eagles and buteonine hawks are heavily built birds that have traditionally been classified together in the large subfamily Buteoninae. In 2005, Heather Lerner and David Mindell proposed separating the eagles into their own subfamilies Aquilinae, Haliaeetinae, and Harpiinae, leaving only the buteo–buteogallus clade in a more restricted Buteoninae. Included in the booted eagles are the genera ''Aquila'', ''Hieraaetus'' and ''Clanga''; all species described as "hawk eagles" including the genera '' Spizaetus'' and ...

French Academy Of Sciences
The French Academy of Sciences (, ) is a learned society, founded in 1666 by Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French Scientific method, scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academy of Sciences, Academies of Sciences. Currently headed by Patrick Flandrin (President of the academy), it is one of the five Academies of the . __TOC__ History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque nationale de France, Bibliothèque Nationale, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the academy's existence were relatively informal, since no statutes had as yet been laid down for the ins ...

Jules Verreaux
Jules Pierre Verreaux (24 August 1807 – 7 September 1873) was a French botanist and ornithologist and a professional collector of and trader in natural history specimens. He was the brother of Édouard Verreaux and nephew of Pierre Antoine Delalande. Career Verreaux worked for the family business, Maison Verreaux, established in 1803 by his father, Jacques Philippe Verreaux, at Place des Vosges in Paris, which was the earliest known company that dealt in objects of natural history. The company funded collection expeditions to various parts of the world. Maison Verreaux sold many specimens to the Muséum National d'Histoire Naturelle to add to its collections. In 1830, while travelling in modern-day Botswana, Verreaux witnessed the burial of a Tswana people, Tswana warrior. Verreaux returned to the burial site under cover of night to dig up the African's body where he retrieved the skin, the skull and a few bones. Verreaux intended to ship the body back to France and so prepar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handbook Of The Birds Of The World
The ''Handbook of the Birds of the World'' (HBW) is a multi-volume series produced by the Spanish publishing house Lynx Edicions in partnership with BirdLife International. It is the first handbook to cover every known living species of bird. The series was edited by Josep del Hoyo, Andrew Elliott, Jordi Sargatal and David A. Christie. All 16 volumes have been published. For the first time an animal class will have all the species illustrated and treated in detail in a single work. This has not been done before for any other group in the animal kingdom. Material in each volume is grouped first by family, with an introductory article on each family; this is followed by individual species accounts (taxonomy, subspecies and distribution, descriptive notes, habitat, food and feeding, breeding, movements, status and conservation, bibliography). In addition, all volumes except the first and second contain an essay on a particular ornithological theme. More than 200 renowned sp ...

René Primevère Lesson
René (''Born again (Christianity), born again'' or ''reborn'' in French language, French) is a common given name, first name in French-speaking, Spanish-speaking, and German-speaking countries. It derives from the Latin name Renatus. René is the masculine form of the name (Renée being the feminine form). In some non-Francophone countries, however, there exists the habit of giving the name René (sometimes spelled without an accent) to girls as well as boys. In addition, both forms are used as surnames (family names). René as a first name given to boys in the United States reached its peaks in popularity in 1969 and 1983 when it ranked 256th. Since 1983 its popularity has steadily declined and it ranked 881st in 2016. René as a first name given to girls in the United States reached its peak in popularity in 1962 when it ranked 306th. The last year for which René was ranked in the top 1000 names given to girls in the United States was 1988. Persons with the given name * Ren ...

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] |
Falconiformes
The order Falconiformes () is represented by the extant family Falconidae, Falconidae (falcons and caracaras) and a handful of enigmatic Paleogene species. Traditionally, the other bird of prey families New World vulture, Cathartidae (New World vultures and condors), Sagittariidae, Sagittariidae (secretarybird), Pandion (bird), Pandionidae (ospreys), and Accipitridae, Accipitridae (hawks) were classified in Falconiformes. A variety of comparative genome analyses published since 2008, however, found that falcons are part of a clade of birds called Australaves, which also includes seriemas, parrots and passerines. Within Australaves falcons are more closely related to the parrot-passerine clade than they are to the seriemas. The hawks, vultures and owls are placed in the clade Afroaves. The cladogram of the Telluraves shown below is based on the study by Josefin Stiller and collaborators published in 2024. The species numbers are taken from the December 2023 version of the list main ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accipitriformes
The Accipitriformes (; ) are an order of birds that includes most of the diurnal birds of prey, including hawks, eagles, vultures, and kites, but not falcons. For a long time, the majority view was to include them with the falcons in the Falconiformes, but many authorities now recognize a separate order Accipitriformes. A DNA study published in 2008 indicated that falcons are not closely related to the Accipitriformes, being instead more closely related to parrots and passerines. Since then, the split and the placement of the falcons next to the parrots in taxonomic order has been adopted by the American Ornithological Society's South American Classification Committee (SACC), its North American Classification Committee (NACC), and the International Ornithological Congress (IOC). The British Ornithologists' Union already recognized the Accipitriformes, and has adopted the move of Falconiformes. The DNA-based proposal and the NACC and IOC classifications include the New World v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
