Damara Red-billed Hornbill
The Damara red-billed hornbill (''Tockus damarensis'') is a species of hornbill in the family Bucerotidae. It is found in southwest Angola and northern Namibia. All five red-billed hornbills were formerly considered conspecific. Description left, In Kunene Region, Namibia Damara red-billed hornbills are small species of African hornbills. They have curved dark to bright red bills with their nostrils on the upper beak close to their eyes. Their heads are covered in greyish-white feathers with dark grey feathers running along the back of their heads and upper half of the neck. Like all red-billed hornbills, Damara red-billed hornbills have wings covered in circles of white feathers surrounded by black or dark brown feathers. Their tail feathers are black on the exterior and white on the interior and their legs are short and grey with small semi-sharp claws at the end. Their bellies are usually greyish white but can also be pure white. Distribution Damara red-billed hornbills can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hornbill
Hornbills (Bucerotidae) are a family (biology), family of bird found in tropical and subtropical Africa, Asia and Melanesia. They are characterized by a long, down-curved bill which is frequently brightly coloured and sometimes has a Casque (anatomy), casque on the upper mandible. Both the common English (language), English and the scientific name of the family refer to the shape of the bill, "buceros" being "cow horn" in Greek language, Greek. Hornbills have a two-lobed kidney. They are the only birds in which the first and second vertebra, neck vertebrae (the atlas (anatomy), atlas and axis (anatomy), axis respectively) are fused together; this probably provides a more stable platform for carrying the bill. The family is omnivorous, feeding on fruit and small animals. They are monogamous breeders nesting in natural cavities in trees and sometimes cliffs. A number of mainly Island, insular species of hornbill with small ranges are Threatened species, threatened with extinction, ...

Namibia
Namibia (, ), officially the Republic of Namibia, is a country in Southern Africa. Its western border is the Atlantic Ocean. It shares land borders with Zambia and Angola to the north, Botswana to the east and South Africa to the south and east. Although Kazungula, it does not border Zimbabwe, less than 200 metres (660 feet) of the Botswanan right bank of the Zambezi, Zambezi River separates the two countries. Namibia gained independence from South Africa on 21 March 1990, following the Namibian War of Independence. Its capital and largest city is Windhoek. Namibia is a member state of the United Nations (UN), the Southern African Development Community (SADC), the African Union (AU) and the Commonwealth of Nations. The driest country in sub-Saharan Africa, Namibia has been inhabited since pre-historic times by the San people, San, Damara people, Damara and Nama people. Around the 14th century, immigration, immigrating Bantu peoples arrived as part of the Bantu expansion. Since ... [...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 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 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 a nest, which is blocked off with a plaster of ...

Conspecific
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nostril
A nostril (or naris , plural ''nares'' ) is either of the two orifices of the nose. They enable the entry and exit of air and other gasses through the nasal cavities. In birds and mammals, they contain branched bones or cartilages called turbinates, whose function is to warm air on inhalation and remove moisture on exhalation. Fish do not breathe through noses, but they do have two (but cyclostomes have merged into one) small holes used for smelling, which can also be referred to as nostrils. In humans, the nasal cycle is the normal ultradian cycle of each nostril's blood vessels becoming engorged in swelling, then shrinking. The nostrils are separated by the septum. The septum can sometimes be deviated, causing one nostril to appear larger than the other. With extreme damage to the septum and columella, the two nostrils are no longer separated and form a single larger external opening. Like other tetrapods, humans have two external nostrils (anterior nares) and two additi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
