Guineafowl (Hamanumida Daedalus) Underside
Guineafowl (; (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. 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 guineafowl; ''Telecrex'' inhabited Mongolia, and may have given rise to the oldest of the true phasianids, such as blood pheasants and eared pheasants, which evolved into high-altitude, montane-adapted species with the rise of the Tibetan Plateau. While modern guineafowl species are endemic to Africa, the helmeted guineafowl has been introduced as a domesticated bird widely elsewhere.

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 Greek may refer to: Greece Anything of, from, or related to Greece, a country in Southern Europe: *Greeks, an ethnic group. *Greek language, a branch of the Indo-European language family. **Proto-Greek language, the assumed last common ancestor ... 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, sexually monomorphic and found in China. References {{Taxonbar, from=Q839855 * Bird genera * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vulturine Guineafowl
The vulturine guineafowl (''Acryllium vulturinum'') is the largest extant species of guineafowl. Systematically, it is only distantly related to other guineafowl genera. Its closest living relative, the white breasted guineafowl, ''Agelastes meleagrides'' inhabit primary forests in Central Africa. It is a member of the bird family Numididae, and is the only member of the genus ''Acryllium''. It is a resident breeder in northeast Africa, from southern Ethiopia through Kenya and just into northern Tanzania. Description The vulturine guineafowl is a large () bird with a round body and small head. It has a longer wings, neck, legs and tail than other guineafowl. The adult has a bare blue face and black neck, and although all other guineafowl have unfeathered heads, this species looks particularly like a vulture because of the long bare neck and head. The slim neck projects from a cape of long, glossy, blue and white hackles. The breast is cobalt blue, and the rest of the body ...

Black Guineafowl
The black guineafowl (''Agelastes niger'') is a member of the guineafowl bird family. It occurs in humid forests in Central Africa. It is a medium-sized black bird with a bare, pink head and upper neck. Little is known of its behaviour. Description The head and upper neck of an adult black guineafowl are unfeathered, revealing the pink skin. A crest of short downy feathers is on the forehead and crown, and the throat and lower neck have a scattering of downy feathers. The body and tail feathers are black with some paler speckled markings on the belly. Males have one to three spurs on their legs, while females either have none or a single short spur. Juveniles are similar, but have buff tips to the feathers on their upper parts, a speckled breast, and white belly. The beak is greenish grey and the legs greyish brown. Males are usually slightly larger than females and measure about in length, weighing about . The call is a monotonous high-pitched "kwee" repeated at the rate of two ...

White-breasted Guineafowl
The white-breasted guineafowl (''Agelastes meleagrides'') is a medium-sized, up to 45 cm long, terrestrial bird of the guineafowl 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 guineafowl is distributed in subtropical West African forests of Côte d'Ivoire, Ghana, Guinea, Liberia, and Sierra Leone. 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 guineafowl is rated as vulnerable on the IUCN Red List.

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 unique ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. 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. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...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 neophyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
