Bleaker St
Bleaker Island () is one of the Falkland Islands, lying off south east Lafonia (the southern peninsula of East Falkland). The name is a corruption of "Breaker Island" due to the waves that break on it. It was also known as "Long Island" at one point. Geography Bleaker Island is long, narrow and low-lying and the southern tip of the Island is separated from Lafonia by a thin stretch of water named 'The Jump'. It has an area of and is long. The island is no wider than at any point and tapers to several thin necks of land at various points down its length. The highest point is Semaphore Hill, at . The western shores of Bleaker Island are low-lying and fringed by shallow stone beaches. The east coast of the island is characterised by low cliffs, interspersed with sand and pebble beaches and gulches and is directly exposed to the Atlantic Ocean. The island has several large ponds and the most impressive beach is the 'Sandy Bay'. History Bleaker Island has been a sheep farm ...

Overgrazing
Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves. It can also be caused by immobile, travel restricted populations of native or non-native wild animals. Overgrazing reduces the usefulness, productivity and biodiversity of the land and is one cause of desertification and erosion. Overgrazing is also seen as a cause of the spread of invasive species of non-native plants and of weeds. Degrading land, emissions from animal agriculture and reducing the biomass in a ecosystem contribute directly to climate change between grazing events. Successful planned grazing strategies have been in support of the American bison of the Great Plains, or migratory wildebeest of the African savannas, or by holistic planned grazing.

Rock Cormorant
The rock shag (''Leucocarbo magellanicus''), also known as the Magellanic cormorant, is a marine cormorant found around the southernmost coasts of South America. Its breeding range is from around Valdivia, Chile, south to Cape Horn and Tierra del Fuego, and north to Punta Tombo in Argentina. In winter it is seen further north, with individuals reaching as far as Santiago, Chile on the west coast and Uruguay on the east. The birds also breed around the coasts of the Falkland Islands. Taxonomy The rock shag was 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 '' Pelecanus'' and coined the binomial name ''Pelecanus magellanicus''. Gmelin based his description on the "Magellanic shag" that had been described in 1785 by the English ornithologist John Latham in his book ''A General Synopsis of Birds''. Latham had in turn based his description on a specime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
King Cormorant
The imperial shag or imperial cormorant (''Leucocarbo atriceps'') is a black-and-white cormorant native to southern South America, islands of the Subantarctic, and the Antarctic Peninsula, primarily in rocky coastal regions, but locally also at large inland lakes. Some taxonomic authorities, including the International Ornithologists' Union, place it in the genus ''Leucocarbo'', others in the genus ''Phalacrocorax''. It is also known as the blue-eyed shag, blue-eyed cormorant and by many other names, and is one of a larger group of cormorants called blue-eyed shags. The taxonomy is complex, and several types are treated as either subspecies or separate species. Taxonomy The taxonomy is complex, and species limits within this group remain unresolved. Some taxonomic authorities, including the International Ornithologists' Union, split the group into the species listed below. Others consider all or part of the group conspecific. The following are part of this group: * Imperial shag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gentoo Penguin
The gentoo penguin ( ) (''Pygoscelis papua'') is a penguin species (or possibly a species complex) in the genus ''Pygoscelis'', most closely related to the Adélie penguin (''P. adeliae'') and the chinstrap penguin (''P. antarcticus''). The earliest scientific description was made in 1781 by Johann Reinhold Forster with a type locality in the Falkland Islands. The species calls in a variety of ways, but the most frequently heard is a loud trumpeting, which the bird emits with its head thrown back. Names The application of "gentoo" to the penguin is unclear. '' Gentoo'' was an Anglo-Indian term to distinguish Hindus from Muslims. The English term may have originated from the Portuguese ''gentio'' ("pagan, gentile"). Some speculate that the white patch on the bird's head was thought to resemble a turban. It may also be a variation of another name for this bird, "Johnny penguin", with Johnny being the Spanish counterpart of and sounding vaguely like gentoo. The Johnny rook, a pr ...

Magellanic Penguin
The Magellanic penguin (''Spheniscus magellanicus'') is a South American penguin, breeding in coastal Patagonia, including Argentina, Chile, and the Falkland Islands, with some bird migration, migrating to Brazil and Uruguay, where they are occasionally seen as far north as Espírito Santo. Vagrants have been found in El Salvador, the Avian Island in Antarctica, Australia, and New Zealand. It is the most numerous of the ''Spheniscus'' banded penguins. Its nearest relatives are the African penguin, the Humboldt penguin, and the Galápagos penguins. The Magellanic penguin was named after Portuguese explorer Ferdinand Magellan, who spotted the birds in 1520. The species is listed as being of Least Concern by the IUCN. Description Magellanic penguins are medium-sized penguins which grow to be tall and weigh between . The males are larger than the females, and the weight of both drops while the parents raise their young. Adults have black backs and white abdomens. There are two b ...

Rockhopper Penguin
The rockhopper penguins are three closely related taxa of crested penguins that have been traditionally treated as a single species and are sometimes split into three species. Not all experts agree on the classification of these penguins. Some consider all three as distinct species, some split the western and eastern forms into the southern rockhopper penguin and keep the northern rockhopper as distinct, while other experts consider all three potential varieties to be one species. Appearance Rockhopper penguins (Eudyptes chrysocome) are among the smaller species of penguin. After reaching full growth, they are about 20 inches or 50 centimetres in height. Males and females cannot be distinguished visually, so a DNA test is conducted by taking a feather from the bird to determine its gender. Like many penguins, rockhopper penguins have a white belly and the rest of their body is black. Some characteristics that differentiate them from the other penguins are their red eyes, orange ...

Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking.

Southern Elephant Seal
The southern elephant seal (''Mirounga leonina'') is one of two species of elephant seals. It is the largest member of the clade Pinnipedia and the order Carnivora, as well as the largest extant marine mammal that is not a cetacean. It gets its name from its massive size and the large proboscis of the adult male, which is used to produce very loud roars, especially during the breeding season. A bull southern elephant seal is about 40% heavier than a male northern elephant seal (''Mirounga angustirostris''), which is nearly twice the weight of a male walrus (''Odobenus rosmarus''), or 6–7 times heavier than the largest living mostly terrestrial carnivorans, the Kodiak bear and the polar bear. Taxonomy The southern elephant seal was one of the many species originally described by Swedish zoologist Carl Linnaeus in the landmark 1758 10th edition of his ''Systema Naturae'', where it was given the binomial name of ''Phoca leonina''.
