African Grey Hornbill
The African grey hornbill (''Lophoceros nasutus'') is a member of the hornbill family of mainly tropical near-passerine birds found in the Old World. It is a widespread resident breeder in much of sub-Saharan Africa and the southwest of the Arabian Peninsula. The African grey hornbill has escaped or been deliberately released into Florida, USA, but there is no evidence that the population is breeding and may only persist due to continuing releases or escapes. Taxonomy In 1760 the French zoologist Mathurin Jacques Brisson included a description of the African grey hornbill in the fourth volume of his ''Ornithologie'' based on a specimen collected in Senegal. He used the French name ''Le calao à bec noir du Sénégal'' and the Latin name ''Hydrocorax Senegalensis Melanorynchos''. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Senegal
Senegal, officially the Republic of Senegal, is the westernmost country in West Africa, situated on the Atlantic Ocean coastline. It borders Mauritania to Mauritania–Senegal border, the north, Mali to Mali–Senegal border, the east, Guinea to Guinea–Senegal border, the southeast and Guinea-Bissau to Guinea-Bissau–Senegal border, the southwest. Senegal nearly surrounds The Gambia, a country occupying a narrow sliver of land along the banks of the Gambia River, which separates Senegal's southern region of Casamance from the rest of the country. It also shares a maritime border with Cape Verde. Senegal's capital is Dakar. Senegal is the westernmost country in the mainland of the Old World, or Afro-Eurasia. It owes its name to the Senegal River, which borders it to the east and north. The climate is typically Sahelian, though there is a wet season, rainy season. Senegal covers a land area of almost and has a population of around 18 million. The state is a Presidential system ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buceros
''Buceros'', from Ancient Greek βοῦς (''boûs''), meaning "ox", and κέρας (''kéras''), meaning "horn", is a genus of large Asian hornbills (family Bucerotidae). Description Hornbills in the genus ''Buceros'' include some of the largest arboreal hornbills in the world, with the largest being the great hornbill. All the hornbills in this genus have a large and hollow bony casque on their upper beak that can be useful to scientists and bird watchers to recognise their age, sex and species. Their wingspan can be up to 1.8 meters (6 foot) and they have the largest wingspan out of all the hornbills. Taxonomy The genus ''Buceros'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. The name comes from Ancient Greek βοῦς (''boûs''), meaning "ox", and κέρας (''kéras''), meaning "horn". The type species was designated as the rhinoceros hornbill (''Buceros rhinoceros'') by Daniel Giraud Elliot in 1882. Sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-billed Hornbill
The red-billed hornbills are a group of hornbills found in the savannas and woodlands of sub-Saharan Africa. They are now usually Lumpers_and_splitters#Biology, split into five species, the northern red-billed hornbill (''Tockus erythrorhynchus''), western red-billed hornbill (''T. kempi''), Tanzanian red-billed hornbill (''T. ruahae''), southern red-billed hornbill (''T. rufirostris'') and Damara red-billed hornbill (''T. damarensis''), but some authorities consider the latter four all subspecies of ''Tockus erythrorhynchus''. Description This group of conspicuous birds have mainly whitish underparts and head, grey upperparts, long tails, and a long curved red bill which lacks a :wikt:casque, casque. The sexes are similar, but the female has a smaller bill. They are generally large, at long, but the entire group is considered one of the smaller hornbills. Behaviour Breeding During incubation, the female lays three to six white eggs in a tree hole that has been converted to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Culmen (bird)
The beak, bill, or Rostrum (anatomy), 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 pecking, wikt:grasp#Verb, grasping, and holding (in wikt:probe#Verb, probing for food, eating, manipulating and carrying objects, predation, killing prey, or fighting), preening, Courtship in animals, 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, rhynchosaurs, anuran tadpoles, monotremes (i.e. echidnas and platypuses, which have a bill-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 epider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carl Jakob Sundevall
Carl Jakob Sundevall (22 October 1801 in Högestad – 2 February 1875) was a Sweden, Swedish zoologist. Sundevall studied at Lund University, where he received a Ph.D. in 1823. After traveling to East Asia, he studied medicine, graduating as a Doctor of Medicine in 1830. He was employed at the Swedish Museum of Natural History, Stockholm, from 1833, and was professor and keeper of the vertebrate section from 1839 to 1871. He wrote ''Svenska Foglarna'' (1856–87), which described 238 species of birds observed in Sweden. He classified a number of birds collected in southern Africa by Johan August Wahlberg. In 1835, he developed a phylogeny for the birds based on the muscles of the hip and leg that contributed to later work by Thomas Huxley. He then went on to examine the arrangement of the deep plantar tendons in the bird's foot. This latter information is still used by avian taxonomists. Sundevall was also an entomologist and arachnologist, for which (for the latter field) in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
