Guinea Fowl
Guinea fowl () (or guineahen) are birds of the family Numididae in the order Galliformes. They are endemic to Africa and rank among the oldest of the gallinaceous birds. Phylogenetics, Phylogenetically, they branched off from the core Galliformes after the Cracidae (chachalacas, guans, and curassows) and before the Odontophoridae (New World quail). An Eocene fossil lineage ''Telecrex'' has been associated with guinea fowl; ''Telecrex'' inhabited Mongolia, and may have given rise to the oldest of the true Phasianidae, phasianids, such as blood pheasants and Crossoptilon, eared pheasants, which Evolution, evolved into high-altitude, montane-adapted species with the rise of the Tibetan Plateau.

Helmeted Guinea Fowl
The helmeted guinea fowl (''Numida meleagris'') is the best known of the guinea fowl bird family, Numididae, and the only member of the genus ''Numida''. It is native to Africa, mainly south of the Sahara, and has been widely introduced, as a Domestic guinea fowl, domesticated species, into the West Indies, North America, Colombia, Brazil, Australia and Europe. Taxonomy The helmeted guinea fowl was Species description, formally described by Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of Systema Naturae, tenth edition of his ''Systema Naturae'' under the binomial nomenclature, binomial name ''Phasianus meleagris''. In 1764, Linnaeus moved the helmeted guinea fowl to the new genus ''Numida''. The genus name ''Numida'' is Latin for "North African". In the early days of the European colonisation of North America, the native wild turkey (''Meleagris gallopavo'') was confused with this species. The word ''meleagris'', Greek language, Greek for guinea fowl, is als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crossoptilon
Eared pheasants are pheasants from the genus ''Crossoptilon'' in the family Phasianidae. Species Established by Brian Houghton Hodgson in 1838, the genus contains four species: The name ''Crossoptilon'' is a combination of the Greek language, Greek words ''krossoi'', meaning "fringe" and , meaning "feather"— a name Hodgson felt particularly applied to the white eared pheasant "distinguished amongst all its congeners by its ample fringe-like plumage, the dishevelled quality of which is communicated even to the central tail feathers". All are large, Sex#Sexual monomorphism, sexually monomorphic and found in China. References {{Taxonbar, from=Q839855 Crossoptilon, * Birds of China, * Taxa named by Brian Houghton Hodgson ...

Vulturine Guinea Fowl
The vulturine guinea fowl (''Acryllium vulturinum'') is the largest extant species of guinea fowl. Systematically, it is only distantly related to other guinea fowl genera. Its closest living relative, the Agelastes meleagrides, white breasted guinea fowl, ''Agelastes meleagrides'' inhabit primary forests in Central Africa. It is a member of the bird family Guinea fowl, Numididae, and is the only member of the genus ''Acryllium''. It is a resident breeder in northeast Africa, from southern Ethiopia and Somalia through Kenya and just into northern Tanzania. Description The vulturine guinea fowl is a large () bird with a round body and small head. It's average weight is between 1kg to 1.6kg and it has longer wings, neck, legs and tail than other guinea fowl. The adult has a bare blue face and black neck, and although all other guinea fowl have unfeathered heads, this species looks particularly like a vulture because of the long bare neck and head. The slim neck projects fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Guinea Fowl
The black guinea fowl (''Agelastes niger'') is a terrestrial bird of the guinea fowl, Numididae (guinea fowl) family found in humid forests in West-Central Africa. It is a medium-sized, black Galliformes, galliforme bird with a bare, orange-pink head and upper neck. As it inhabits dense, potentially inaccessible, regions of equatorial African jungle, little is known of black guinea fowl behaviour or habits. By all accounts, it is a more reclusive, secretive bird when compared to the other, more sociable guinea fowl species; i.e., researchers have been able to successfully observe and document far more information on the confident, gregarious and open grassland-dwelling helmeted guinea fowl (''Numidia meleagris''), or even the more exotic vulturine guinea fowl (''Acryllium vulturinum''). Compared to the black guinea fowl, the aforementioned species (and most guinea fowl) tend to be found in more exposed, dry savanna and arid open forest habitat, and congregate in larger communal fl ...

White-breasted Guinea Fowl
The white-breasted guinea fowl (''Agelastes meleagrides'') is a medium-sized, up to 45 cm long, terrestrial bird of the guinea fowl family. Description It has a black plumage with a small, bare, red head, white breast, long, black tail, greenish-brown bill, and greyish feet. The sexes are similar, although the female is slightly smaller than the male. Distribution The white-breasted guinea fowl is distributed in subtropical West African forests of Ivory Coast, Ghana, Guinea, Liberia, and Sierra Leone. Although preferring a more dry climate, the species prioritizes forest coverage causing the distribution of the species to have a much broader distribution. Diet Its diet consists mainly of seeds, berries, termites, and small animals. Conservation Due to ongoing habitat loss and hunting in some areas, the white-breasted guinea fowl is rated as vulnerable on the IUCN Red List The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, als ...

Taxonomic Order
Taxonomic sequence (also known as systematic, phyletic or taxonomic order) is a sequence followed in listing of taxa which aids ease of use and roughly reflects the evolutionary relationships among the taxa. Taxonomic sequences can exist for taxa within any rank, that is, a list of families, genera, species can each have a sequence. Early biologists used the concept of "age" or "primitiveness" of the groups in question to derive an order of arrangement, with "older" or more "primitive" groups being listed first and more recent or "advanced" ones last. A modern understanding of evolutionary biology has brought about a more robust framework for the taxonomic ordering of lists. A list may be seen as a rough one-dimensional representation of a phylogenetic tree. Taxonomic sequences are essentially heuristic devices that help in arrangements of linear systems such as books and information retrieval systems. Since phylogenetic relationships are complex and non-linear, there is no uniq ... [...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] |

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
