City Of Cape Town
The City of Cape Town ( af, Stad Kaapstad; xh, IsiXeko saseKapa) is the metropolitan municipality which governs the city of Cape Town, South Africa and its suburbs and exurbs. As of the 2011 census, it had a population of 3,740,026. The remote Prince Edward Islands are deemed to be part of the City of Cape Town, specifically of ward 115. Cllr. Ian McMahon is the current ward councilor of ward 115. History Cape Town first received local self-government in 1839, with the promulgation of a municipal ordinance by the government of the Cape Colony. When it was created, the Cape Town municipality governed only the central part of the city known as the City Bowl, and as the city expanded, new suburbs became new municipalities, until by 1902 there were 10 separate municipalities in the Cape Peninsula. During the 20th century, many of the inner suburban municipalities became unsustainable; in 1913 the first major unification took place when the municipalities of Cape Town, Green ...

Contour Line
A contour line (also isoline, isopleth, or isarithm) of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value. It is a plane section of the three-dimensional graph of the function f(x,y) parallel to the (x,y)-plane. More generally, a contour line for a function of two variables is a curve connecting points where the function has the same particular value. In cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes. The contour interval of a contour map is the difference in elevation between successive contour lines. The gradient of the function is always perpendicular to the contour lines. When the lines are close together the magnitude of the gra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anthropoides Paradiseus
The blue crane (''Grus paradisea''), also known as the Stanley crane and the paradise crane, is the national bird of South Africa. The species is listed as Vulnerable by the IUCN. Description The blue crane is a tall, ground-dwelling bird, but is fairly small by the standards of the crane family. It is tall, with a wingspan of and weighs . Among standard measurements, the wing chord measures , the exposed culmen measures and the tarsus measures . This crane is pale blue-gray in color becoming darker on the upper head, neck and nape. From the crown to the lores, the plumage is distinctly lighter, sometimes whitish. The bill is ochre to greyish, with a pink tinge. The long wingtip feathers which trail to the ground. The primaries are black to slate grey, with dark coverts and blackish on the secondaries. Unlike most cranes, it has a relatively large head and a proportionately thin neck. Juveniles are similar but slightly lighter, with tawny coloration on the head, and no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phoenicopterus Minor
The lesser flamingo (''Phoeniconaias minor'') is a species of flamingo occurring in sub-Saharan Africa and western India. Birds are occasionally reported from further north, but these are generally considered vagrants. Characteristics The lesser flamingo is the smallest species of flamingo, though it is a tall and large bird by most standards. The species can weigh from . The standing height is around . The total length (from beak to tail) and wingspan are in the same range of measurements, from . Most of the plumage is pinkish white. The clearest difference between this species and the greater flamingo, the only other Old World species of flamingo, is the much more extensive black on the bill. Size is less helpful unless the species are together, since the sexes of each species also differ in height. The extinct species ''Phoeniconaias proeses'' in the same genus, from the Pliocene of Australia, is thought to have been even smaller. The lesser flamingo may be the most numerous ...

Mudflats
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, Aust ...

Wader

The term "wader" is used in Europe, while "shorebird" is used in North America, where "wader" may be used instead to refer to long-legged wading birds such as storks and herons. There are about 210 species of wader, most of which live in wetland or coastal environments. Many species of Arctic and temperate regions are strongly migratory, but tropical birds are often resident, or move only in response to rainfall patterns. Some of the Arctic species, such as the little stint, are amongst the longest distance migrants, spending the non- breeding season in the southern hemisphere. Many of the smaller species found ...

Wetland
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or saltwater. The main wetland typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterbird
A water bird, alternatively waterbird or aquatic bird, is a bird that lives on or around water. In some definitions, the term ''water bird'' is especially applied to birds in freshwater ecosystems, although others make no distinction from seabirds that inhabit marine environments. Some water birds (e.g. wading birds) are more terrestrial while others (e.g. waterfowls) are more aquatic, and their adaptations will vary depending on their environment. These adaptations include webbed feet, beaks, and legs adapted to feed in the water, and the ability to dive from the surface or the air to catch prey in water. The term ''aquatic bird'' is sometimes also used in this context. A related term that has a narrower meaning is waterfowl. Some piscivorous birds of prey, such as ospreys and sea eagles, hunt aquatic prey but do not stay in water for long and lives predominantly over dry land, and are not considered water birds. The term waterbird is also used in the context of conservat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Port Of Cape Town
The Port of Cape Town is the port of the city of Cape Town, South Africa. It is situated in Table Bay. Because of its position along one of the world's busiest trade routes it is one of the busiest ports in South Africa, handling the largest amount of fresh fruit and second only to Durban as a container port. The port also has significant repair and maintenance facilities that are used by several large fishing fleets and parts of the West African oil industry. Because of the many tourist attractions offered by Cape Town and its surrounding region, many cruise ships also berth in the port. History The history of the port follows that of Cape Town, which traces its roots back to 6 April 1652 when Jan van Riebeeck of the Dutch East India Company (VOC) established a revictualing station there. Earlier explorers had called it Table Bay from the late 15th century onwards. The first harbour construction was a jetty built in 1654 by Jan van Riebeeck. Ships all anchored in ...
