Snowy Albatross
The snowy albatross (''Diomedea exulans''), also known as the wandering albatross, white-winged albatross, or goonie, is a large seabird from the family Diomedeidae; they have a circumpolar range in the Southern Ocean. It is the largest species of albatross and was long considered to be the same species as the Tristan albatross and the Antipodean albatross. Together with the Amsterdam albatross, it forms the wandering albatross species complex, which some began referring to more recently as "snowy". The snowy albatross is one of the two largest members of the genus ''Diomedea'' (the great albatrosses), being similar in size to the southern royal albatross. It has the greatest known wingspan of any living bird and is also one of the most far-ranging birds. Some individual snowy albatrosses are known to circumnavigate the Southern Ocean three times in one year, covering more than . Taxonomy The taxonomic history of this species is long and complicated. The species was first de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diomedes
Diomedes (Jones, Daniel; Roach, Peter, James Hartman and Jane Setter, eds. ''Cambridge English Pronouncing Dictionary''. 17th edition. Cambridge UP, 2006.) or Diomede (; ) is a hero in Greek mythology, known for his participation in the Trojan War. He was born to Tydeus and Deipyle and later became King of Argos, Peloponnese, Argos, succeeding his maternal grandfather, Adrastus. In Homer's ''Iliad'' Diomedes is regarded alongside Ajax the Great and Agamemnon, after Achilles, as one of the best warriors of all the Achaeans (Homer), Achaeans in prowess (which is especially made clear in Book 7 of the ''Iliad'' when Ajax the Greater, Diomedes, and Agamemnon are the most wished for by the Achaeans to fight Hector out of nine volunteers, who included Odysseus and Ajax the Lesser). Subsequently, Diomedes founded ten or more Italian cities and, after his death, was worshipped as a divine being under various names in both Italy and Greece.

Macquarie Island
Macquarie Island is a subantarctic island in the south-western Pacific Ocean, about halfway between New Zealand and Antarctica. It has been governed as a part of Tasmania, Australia, since 1880. It became a Protected areas of Tasmania, Tasmanian State Reserve in 1978 and was inscribed as a UNESCO World Heritage Site in 1997. Macquarie Island is an exposed portion of the Macquarie Fault Zone, Macquarie Ridge and is located where the Australian Plate meets the Pacific Plate. The island is home to the entire royal penguin population during their annual nesting season. Ecologically, the island is part of the Antipodes Subantarctic Islands tundra ecoregion. History 19th century Frederick Hasselborough, an Australian, discovered the uninhabited island on 11 July 1810, while looking for new seal hunting, sealing grounds. He claimed Macquarie Island for United Kingdom, Britain and annexation, annexed it to the colony of New South Wales in 1810. The island was named for Colonel Lachla ...

Crozet Islands
The Crozet Islands (; or, officially, ''Archipel Crozet'') are a sub-Antarctic archipelago of small islands in the southern Indian Ocean. They form one of the five administrative districts of the French Southern and Antarctic Lands. History Discovery and early history The Crozet Islands were discovered on 24 January 1772, by the expedition of French explorer Marc-Joseph Marion du Fresne, aboard ''Le Mascarin''. His second-in-command, Julien-Marie Crozet, landed on ÃŽle de la Possession, claiming the archipelago for France. In 1776, Crozet met James Cook at Cape Town, at the start of Cook's third voyage. Crozet shared the charts of his ill-fated expedition, and as Cook sailed eastward, he stopped at the islands, naming the western group ''Marion'' and the eastern group ''Crozet''. In the following years, sealers visiting the islands referred to both the eastern and western groups as the Crozet Islands, and Marion Island became the name of the larger of the two Prince Edward ...

Bird Island, South Georgia
Bird Island () is long and wide, separated from the western end of South Georgia by Bird Sound. It is part of the British overseas territory of South Georgia and the South Sandwich Islands, also claimed by Argentina as part of Tierra del Fuego province. History It was discovered in 1775 by a British expedition under James Cook, who so named it "on account of the vast numbers f birdsthat were upon it". In the late 1950s, the island was the subject of a number of US-funded projects. Between 1959–62, a great number of the island's wandering albatross were ringed, which gave startling data about their range - one bird was found in Australia. The island is currently a Site of Special Scientific Interest, and so there are no landings allowed without permission. The summit of the island, Roché Peak, is named after the Englishman Anthony de la Roché who discovered South Georgia in 1675. Farewell Point forms the northeast extremity of Bird Island. The second highest peak o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the opposite wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan of , the official record for a living bird. The term wingspan, more technically 'extent' , is also used for other winged animals such as pterosaurs, bats, insects, etc., and other aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is the distance between the length from the end of an individual's arm (measured at the fingertips) to the individual's fingertips on the other arm when raised parallel to the ground at shoulder height. Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, regardless of wing shape or sweep. Implications for aircraft design and animal evolution The lift from wings is proportional to their area, so the h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salt Gland
The salt gland is an organ (anatomy), organ for excreting excess salt (chemistry), salts. It is found in the cartilaginous fishes subclass elasmobranchii (sharks, rays, and skates), seabirds, and some reptiles. Salt glands can be found in the rectum of sharks. Birds and reptiles have salt glands located in or on the skull, usually in the eyes, nose, or mouth. These glands are lobed containing many secretory tubules which radiate outward from the excretory canal at the center. Secretory tubules are lined with a single layer of epithelial cells. The diameter and length of these glands vary depending on the salt uptake of the species. Salt glands maintain osmoregulation, salt balance and allow marine vertebrates to drink seawater. Active transport via sodium–potassium pump, found on the basolateral membrane, moves salt from the blood into the gland, where it is excreted as a concentrated Solution (chemistry), solution. In birds The avian salt gland has two main ducts: a medi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plumage
Plumage () is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morph (zoology), morphs. The placement of feathers on a bird is not haphazard but rather emerges in organized, overlapping rows and groups, and these are known by standardized names. Most birds moult twice a year, resulting in a breeding or ''nuptial plumage'' and a ''basic plumage''. Many ducks and some other species such as the red junglefowl have males wearing a bright nuptial plumage while breeding and a drab ''eclipse plumage'' for some months afterward. The painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the ''juvenile plumage'' with an ''auxiliary formative plumage''; the second a month o ...
