Vanellus Armatus
The blacksmith lapwing or blacksmith plover (''Vanellus armatus'') is a lapwing species that occurs commonly from Kenya through central Tanzania to southern and southwestern Africa. The vernacular name derives from the repeated metallic 'tink, tink, tink' alarm call, which suggests a blacksmith's hammer striking an anvil. Description Blacksmith lapwings are very boldly patterned in black, grey and white, possibly warning colours to predators. It is one of five lapwing species (two African, one Asian and two Neotropical) that share the characteristics of red eyes and a bold pied plumage, with a carpal (wing) spur adorning the wrist joint; a sharp black protrusion which they use to aggressively defend their young from potential threats, through persistent aerial dives typically targeting the head. The portions of the bird's body bare to plumage average a black coloration for the bill, and either a black or white-grey dappling on the legs. Females average larger and heavier but the ...

Etosha National Park
Etosha National Park is a national park in northwestern Namibia and one of the largest national parks in Africa. It was proclaimed a game reserve in March 1907 in Ordinance 88 by the Governor of German South West Africa, Friedrich von Lindequist. It was designated as ''Wildschutzgebiet'' in 1958, and was elevated to the status of a national park in 1967 by an act of parliament of the Republic of South Africa. It spans an area of and gets its name from the large Etosha pan which is almost entirely within the park. With an area of , the Etosha pan covers 23% of the total area of the national park. The area is home to hundreds of species of mammals, birds and reptiles, including several threatened and endangered species such as the black rhinoceros. The park is located in the Kunene region and shares boundaries with the regions of Oshana, Oshikoto and Otjozondjupa. History Areas north of the Etosha pan were inhabited by Ovambo people, while various Otjiherero-speaking groups ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birds Described In 1822
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 ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have 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 further evolved for swimming. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vanellus
''Vanellus'' is the genus of waders which provisionally contains all lapwings except red-kneed dotterel, ''Erythrogonys cinctus''. The name "''vanellus''" is Latin for "little fan", ''vanellus'' being the diminutive of ''vannus'' ("Winnowing#In Greek culture, winnowing fan"). The name is in reference to the sound lapwings' wings make in flight. Description These long-legged waders mostly have strongly patterned plumage. Although the most familiar Eurasian lapwing, ''Vanellus vanellus'' (northern lapwing), has a wispy Crest (feathers), crest, only two other species do so. Red or yellow facial wattle (anatomy), wattles are a more typical decoration. Only northern, sociable, white-tailed, grey-headed and brown-chested lapwings are truly bird migration, migratory species. The Andean lapwing moves downhill in winter. Spur-winged, blacksmith, river, southern, Andean and pied lapwings are boldly patterned, red-eyed species with a spurred carpal (wrist) joint. Many species have wattle ...

Etosha Pan
The Etosha Pan is a large endorheic salt pan, forming part of the Cuvelai-Etosha Basin in the north of Namibia. It is a hollow in the ground in which water may collect or in which a deposit of salt remains after water has evaporated. The 120-kilometre-long (75-mile-long) dry lakebed and its surroundings are protected as Etosha National Park, Namibia's second-largest wildlife park, covering . The pan is mostly dry but after a heavy rain it will acquire a thin layer of water, which is heavily salted by the mineral deposits on the surface. Location and description Etosha, meaning 'Great White Place' in Oshindonga, is made of a large mineral pan. The area exhibits a characteristic white and greenish surface, which spreads over . The pan is believed to have developed through tectonic plate activity over about ten million years. Around 16,000 years ago, when ice sheets were melting across the land masses of the Northern Hemisphere, a wet climate phase in southern Africa filled Etos ...

Okavango Delta
The Okavango Delta (or Okavango Grassland; formerly spelled "Okovango" or "Okovanggo") in Botswana is a swampy inland delta formed where the Okavango River reaches a tectonic trough at an altitude of 930–1,000 m in the central part of the endorheic basin of the Kalahari. All the water reaching the delta is ultimately evaporated and transpired and does not flow into any sea or ocean. Each year, about of water spreads over the area. Some flood waters drain into Lake Ngami. The area was once part of Lake Makgadikgadi, an ancient lake that had mostly dried up by the early Holocene. The Moremi Game Reserve, a national park, is on the eastern side of the delta. The delta was named as one of the Seven Natural Wonders of Africa, which were officially declared on 11 February 2013 in Arusha, Tanzania. On 22 June 2014, the Okavango Delta became the 1000th site to be officially inscribed on the UNESCO World Heritage List. Geography Floods The Okavango is produced by seasonal flood ...

Lake Nakuru
Lake Nakuru is one of the Rift Valley lakes at an elevation of above sea level. It lies to the south of Nakuru, in the rift valley of Kenya and is protected by Lake Nakuru National Park. The lake's abundance of algae used to attract a vast quantity of flamingos that famously lined the shore. Other birds also flourish in the area, as do warthogs, baboons and other large mammals. Eastern black rhinos and southern white rhinos have also been introduced. The lake's level dropped dramatically in the early 1990s but has since largely recovered. In 2013, the lake received an alarming increase in the water levels that led to the migration of flamingos to Lake Bogoria in search for food supply. Between 2010-2020 Lake Nakuru increased in surface area from 40 to 68 square kilometres. 677 households, parts of Nakuru town and National Park areas had been flooded. Nakuru means "Dust or Dusty Place" in the Maasai language. Lake Nakuru National Park, close to Nakuru town, was established in ...

Lapwing
Lapwings (subfamily Vanellinae) are any of various ground-nesting birds (family Charadriidae) akin to plovers and dotterels. They range from in length, and are noted for their slow, irregular wingbeats in flight and a shrill, wailing cry. A group of lapwings is called a "deceit". The traditional terms "plover", "lapwing", and "dotterel" do not correspond exactly to current taxonomic models; thus, several of the Vanellinae are often called plovers, and one a dotterel, while a few of the "true" plovers (subfamily Charadriinae) are known colloquially as lapwings. In general, a lapwing can be thought of as a larger plover. In Europe's Anglophone countries, ''lapwing'' refers specifically to the northern lapwing, the only member of this group to occur in most of the continent and thus the first bird to go by the English name ''lapwing'' (also known as ''peewit'' or ''pyewipe''). Systematics While authorities generally agree that there about 25 species of Vanellinae, classificati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
African Jacana
The African jacana (''Actophilornis africanus'') is a wader in the family Jacanidae. It has long toes and long claws that enables it to walk on floating vegetation in shallow lakes, its preferred habitat. It is widely distributed in sub-Saharan Africa. For the origin and pronunciation of the name, see Jacanidae. Taxonomy The African jacana was Species description, formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it in the genus ''Parra'' and coined the binomial nomenclature, binomial name ''Parra africana''. Gmelin based his description on that by the English ornithologist John Latham (ornithologist), John Latham who in 1785 had described and illustrated the species in his ''A General Synopsis of Birds''. Gmelin and Latham gave the type locality (biology), locality as "Africa": this was restricted to Ethiopia in 1915. The African jacana is now placed in the genus ''Act ...

Mud Flats
Mudflats or mud flats, also known as tidal flats or, in Ireland, slob or slobs, are coastal wetlands that form in intertidal areas where sediments have been deposited by tides or rivers. A global analysis published in 2019 suggested that tidal flat ecosystems are as extensive globally as mangroves, covering at least of the Earth's surface. / They are found in sheltered areas such as bays, bayous, lagoons, and estuaries; they are also seen in freshwater lakes and salty lakes (or inland seas) alike, wherein many rivers and creeks end. Mudflats may be viewed geologically as exposed layers of bay mud, resulting from deposition of estuarine silts, clays and aquatic animal detritus. Most of the sediment within a mudflat is within the intertidal zone, and thus the flat is submerged and exposed approximately twice daily. A recent global remote sensing analysis estimated that approximately 50% of the global extent of tidal flats occurs within eight countries (Indonesia, China, Australia ...
