Brash Island
Brash Island is an isolated island lying northwest of Darwin Island, off the southeast end of Joinville Island. It was surveyed by the Falkland Islands Dependencies Survey in 1953, and so named by the UK Antarctic Place-Names Committee because the island lies in an area where there is a frequent occurrence of "brash ice" (an accumulation of floating ice made up of fragments not more than 2 m across). Important Bird Area The island has been identified as a 63 ha Important Bird Area (IBA) by BirdLife International BirdLife International is a global partnership of non-governmental organizations that strives to conserve birds and their habitats. BirdLife International's priorities include preventing extinction of bird species, identifying and safeguarding ... because it supports about 166,000 breeding pairs of pygoscelid penguins – probably mainly either Adélie or chinstrap penguins – based on a 2014 estimate from satellite imagery.

Darwin Island (Antarctica)
Darwin Island is the largest of the Danger Islands, lying east-southeast of the eastern tip of Joinville Island, off the northeast end of the Antarctic Peninsula. It was discovered in 1842 by a British expedition under James Clark Ross, and named by him for Charles Darwin Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology.

Joinville Island
Joinville Island is the largest island of the Joinville Island group, about long in an east-west direction and wide, lying off the northeastern tip of the Antarctic Peninsula, from which it is separated by the Antarctic Sound. Joinville Island was discovered and charted roughly during 1838 by a French expedition commanded by Captain Jules Dumont d'Urville, who named it for Prince François, Prince of Joinville (1818–1900), the third son of Louis-Philippe, Duke of Orléans. It is within the Argentine, British and Chilean Antarctic claims. Geography Joinville Island consists of a series of valleys and bays, including Suspiros Bay and Balaena Valley.

Falkland Islands Dependencies Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office.

UK Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by Scientific Committee on Antarctic Research, SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica.

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. History In 1985, following a specific request from the European Economic Community, Birdlife International ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BirdLife International
BirdLife International is a global partnership of non-governmental organizations that strives to conserve birds and their habitats.

Pygoscelis
The genus ''Pygoscelis'' ("rump-legged") contains three living species of penguins collectively known as "brush-tailed penguins". Taxonomy Mitochondrial and nuclear DNA evidence suggests the genus split from other penguins around 38 million years ago, about 2 million years after the ancestors of the genus ''Aptenodytes''. In turn, the Adelie penguins split off from the other members of the genus around 19 million years ago. ;Extant species A 2020 study found that the gentoo penguin may actually comprise a species complex of 4 similar but genetically distinct species: the northern gentoo penguin (''P. papua''), the southern gentoo penguin (''P. ellsworthi''), the eastern gentoo penguin (''P. taeniata''), and the newly-described South Georgia gentoo penguin (''P. poncetii''). However, in 2021 the International Ornithological Congress recognized these as being subspecies of ''P. papua''. A study has estimated that there are about 3.79 million pairs of Adélie, 387,000 pairs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adélie Penguin
The Adélie penguin (''Pygoscelis adeliae'') is a species of penguin common along the entire coast of the Antarctic continent, which is the only place where it is found. It is the most widespread penguin species, and, along with the emperor penguin, is the most southerly distributed of all penguins. It is named after Adélie Land, in turn named for Adèle Dumont d'Urville, who was married to French explorer Jules Dumont d'Urville, who first discovered this penguin in 1840. Adélie penguins obtain their food by both predation and foraging, with a diet of mainly krill and fish. Taxonomy and systematics The first Adélie penguin specimens were collected by crew members of French explorer Jules Dumont d'Urville on his expedition to Antarctica in the late 1830s and early 1840s. Jacques Bernard Hombron and Honoré Jacquinot, two French surgeons who doubled as naturalists on the journey, described the bird for science in 1841, giving it the scientific name ''Catarrhactes adeli ...
