Campbell Island Snipe
The Campbell snipe (''Coenocorypha aucklandica perseverance''), also known as the Campbell Island snipe, is a rare subspecies of the Subantarctic snipe, endemic to Campbell Island, a subantarctic island south of New Zealand in the Southern Ocean. It was not formally described until January 2010.Miskelly & Baker (2010a, b). The subspecific name alludes to the name of the sealing brig ''Perseverance'', captained by Frederick Hasselborough, that discovered Campbell Island in 1810, and which probably inadvertently introduced rats to the island when it was wrecked there in 1828.DOC media release (2010). History The existence of the Campbell snipe was unknown until 1997 when, during a search for the Campbell teal, there was the chance discovery of a small population on an almost inaccessible rock, Jacquemart Island. Thus there is not much information about it and it remains one of the least known birds in the world.Miskelly & Fraser (2006). Austral snipe are extinct on the main ...

Birds Of The Campbell Islands
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the Common ostrich, 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 Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coenocorypha
The austral snipes, also known as the New Zealand snipes or tutukiwi, are a genus, ''Coenocorypha'', of tiny birds in the sandpiper family (biology), family, which are now only found on New Zealand outlying islands, New Zealand's outlying islands. There are currently three living species and six known extinct species, with the Subantarctic snipe having three subspecies, including the Campbell Island snipe discovered as recently as 1997. The genus was once distributed from Fiji, New Caledonia and Norfolk Island, across New Zealand and southwards into New Zealand's subantarctic islands, but predation by introduced species, especially rats, has drastically reduced their range. Taxonomy and range The relationship between ''Coenocorypha'' snipe and the snipes of the genus ''Gallinago'' is uncertain. ''Coenocorypha'' is sometimes thought to be a relict taxon of an ancient lineage;Tennyson, A., & Martinson, P. (2006). ''Extinct Birds of New Zealand''. Te Papa Press, Wellington . however ...

Jacquemart Island
Jacquemart Island, one of the islets surrounding Campbell Island in New Zealand, lies south of Campbell Island and is the southernmost island of New Zealand. The name commemorates Captain J. Jacquemart, of the vessel FRWS ''Vire'', that supported the French 1874 Transit of Venus Expedition to Campbell Island. Geography Jacquemart Island consists of a stack with an area of , being about in length by in width and surrounded by precipitous cliffs at least high at their lowest. Its highest point is about asl. It is an eroded remnant of basaltic lavas originally laid down on a sedimentary base. Because of its inaccessibility from the sea, the first visit by humans to the island did not take place until 29 December 1980 when a small party of scientists was landed by helicopter on the summit ridge for a 90-minute survey. Subsequent short visits were made in 1984 and 1997.Foggo, M.N.; & Meurk, Colin D. (1981)Notes on a visit to Jacquemart Island in the Campbell Island Group ' ...

Campbell Teal
The Campbell teal or Campbell Island teal (''Anas nesiotis'') is a small, flightless, nocturnal species of dabbling duck of the genus ''Anas'' endemic to the Campbell Island group of New Zealand. It is sometimes considered conspecific with the brown teal. The plumage is similar to that of the Auckland teal, dark sepia with the head and back tinged with green iridescence, and a chestnut breast on the male, with the female dark brown all over. Its natural habitat is tussock grassland dominated by '' Poa'' tussock grass, ferns and megaherbs. The species also uses the burrows and pathways of petrel species that nest on the islands. They are apparently territorial in the wild, and probably feed on amphipods and insects. The IUCN classifies it as vulnerable. Conservation left The Campbell teal was once found on Campbell Island, but was driven to extinction there by the introduction of Norway Rats (which ate their eggs and chicks), and was for a while presumed extinct. In 1975 it was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shipwreck
A shipwreck is the wreckage of a ship that is located either beached on land or sunken to the bottom of a body of water. Shipwrecking may be intentional or unintentional. Angela Croome reported in January 1999 that there were approximately three million shipwrecks worldwide (an estimate rapidly endorsed by UNESCO and other organizations). When a ship's crew has died or abandoned the ship, and the ship has remained adrift but unsunk, they are instead referred to as ghost ships. Types Historic wrecks are attractive to maritime archaeologists because they preserve historical information: for example, studying the wreck of revealed information about seafaring, warfare, and life in the 16th century. Military wrecks, caused by a skirmish at sea, are studied to find details about the historic event; they reveal much about the battle that occurred. Discoveries of treasure ships, often from the period of European colonisation, which sank in remote locations leaving few livin ...

Brown Rat
The brown rat (''Rattus norvegicus''), also known as the common rat, street rat, sewer rat, wharf rat, Hanover rat, Norway rat, Norwegian rat and Parisian rat, is a widespread species of common rat. One of the largest muroids, it is a brown or grey rodent with a head and body length of up to long, and a tail slightly shorter than that. It weighs between . Thought to have originated in northern China and neighbouring areas, this rodent has now spread to all continents except Antarctica, and is the dominant rat in Europe and much of North America. With rare exceptions, the brown rat lives wherever humans live, particularly in urban areas. Selective breeding of the brown rat has produced the fancy rat (rats kept as pets), as well as the laboratory rat (rats used as model organisms in biological research). Both fancy rats and laboratory rats are of the domesticated subspecies ''Rattus norvegicus domestica''. Studies of wild rats in New York City have shown that populations livi ...

Brig
A brig is a type of sailing vessel defined by its rig: two masts which are both square rig, square-rigged. Brigs originated in the second half of the 18th century and were a common type of smaller merchant vessel or warship from then until the latter part of the 19th century. In commercial use, they were gradually replaced by fore-and-aft rigged vessels such as schooners, as owners sought to reduce crew costs by having rigs that could be handled by fewer men. In Royal Navy use, brigs were retained for training use when the battle fleets consisted almost entirely of iron-hulled steamships. Brigs were prominent in the coasting coal trade of British waters. 4,395 voyages to London with coal were recorded in 1795. With an average of eight or nine trips per year for one vessel, that is a fleet of over 500 colliers trading to London alone. Other ports and coastal communities were also be served by colliers trading to Britain's coal ports. In the first half of the 19th century, the va ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seal Hunting
Seal hunting, or sealing, is the personal or commercial hunting of seals. Seal hunting is currently practiced in ten countries: United States (above the Arctic Circle in Alaska), Canada, Namibia, Denmark (in self-governing Greenland only), Iceland, Norway, Russia, Finland and Sweden. Most of the world's seal hunting takes place in Canada and Greenland. The Canadian Department of Fisheries and Oceans (DFO) regulates the seal hunt in Canada. It sets quotas (total allowable catch – TAC), monitors the hunt, studies the seal population, works with the Canadian Sealers' Association to train sealers on new regulations, and promotes sealing through its website and spokespeople. The DFO set harvest quotas of over 90,000 seals in 2007; 275,000 in 2008; 280,000 in 2009; and 330,000 in 2010. The actual kills in recent years have been less than the quotas: 82,800 in 2007; 217,800 in 2008; 72,400 in 2009; and 67,000 in 2010. In 2007, Norway claimed that 29,000 harp seals were killed, Russ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
