Ptilopachus Nahani
Nahan's partridge (''Ptilopachus nahani''), also known as the Nahan's francolin, is a bird traditionally placed in the family Phasianidae. As suggested by its alternative name, it was formerly believed to be a francolin and placed either in ''Francolinus'' or ''Pternistis'', but it is now known that its closest relative is the stone partridge and together may in fact be the only African representatives of the New World quails (Odontophoridae).Crowe, T.

Description At about in length, the Nahan's partridge is a relatively small, terrestrial bird with a red eye-ring, legs and base of the bill, brownish upperparts, and black-and-white underparts and head.

Alphonse Joseph Charles Dubois
Alphonse Joseph Charles Dubois (18 October 1839 at Aix-la-Chapelle – 1 June 1921 at Koksijde, Coxyde-sur-Mer) was a Belgian naturalist. He took a doctorate in medicine, and in 1869 became curator of the department of vertebrates at the Royal Belgian Institute of Natural Sciences, Royal Museum of Natural History in Brussels. He worked with his father, Charles Frédéric Dubois (1804–1867), in the production of ''Les Oiseaux de l’Europe et leurs œufs'', completing it after his father’s death. The book was in two volumes, the second consisting of illustrations by Dubois senior. He produced the two-volume ''La Faune illustrée des Vertébrés de la Belgique''.

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Central Africa
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have furth ...

Ptilopachus
''Ptilopachus'' is an African genus of birds in the New World quail family. Taxonomy The genus ''Ptilopachus '' was introduced in 1837 by the English naturalist William Swainson to accommodate a single species, the stone partridge, which is therefore the type species. The genus name is from Ancient Greek ''ptilon'' meaning "feather" with ''pakhus'' meaning "thick" or "dense". As traditionally defined, only the stone partridge was included in this genus, but based on Genetics, genetic evidence, it now also includes Nahan's partridge (formerly considered a francolin). The study also concludes that this genus is more closely related to the New World quails (Odontophoridae) and might be considered their only African representative.

Habitat Loss
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and Abundance (ecology), species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the Exploitation of natural resources, use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduced species, introduction of invasive species, ecosystem nutrient depletion, water pollution, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and lo ... [...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 ...

Uganda
Uganda, officially the Republic of Uganda, is a landlocked country in East Africa. It is bordered to the east by Kenya, to the north by South Sudan, to the west by the Democratic Republic of the Congo, to the south-west by Rwanda, and to the south by Tanzania. The southern part includes a substantial portion of Lake Victoria, shared with Kenya and Tanzania. Uganda is in the African Great Lakes region, lies within the Nile basin, and has a varied equatorial climate. , it has a population of 49.3 million, of whom 8.5 million live in the capital and largest city, Kampala. Uganda is named after the Buganda, Buganda kingdom, which encompasses a large portion of the south, including Kampala, and whose language Luganda is widely spoken; the official language is English. The region was populated by various ethnic groups, before Bantu and Nilotic groups arrived around 3,000 years ago. These groups established influential kingdoms such as the Empire of Kitara.

Terrestrial Animal
Terrestrial animals are animals that live predominantly or entirely on land (e.g. cats, chickens, ants, most spiders), as compared with aquatic animals, which live predominantly or entirely in the water (e.g. fish, lobsters, octopuses), and semiaquatic animals, which rely on both aquatic and terrestrial habitats (e.g. platypus, most amphibians). Some groups of insects are terrestrial, such as ants, butterflies, earwigs, cockroaches, grasshoppers and many others, while other groups are partially aquatic, such as mosquitoes and dragonflies, which pass their larval stages in water. Alternatively, terrestrial is used to describe animals that live on the ground, as opposed to arboreal animals that live in trees. Ecological subgroups The term "terrestrial" is typically applied to species that live primarily on or in the ground, in contrast to arboreal species, who live primarily in trees, even though the latter are actually a specialized subgroup of the terre ...
