Barrow's Goldeneye
Barrow's goldeneye (''Bucephala islandica'') is a medium-sized sea duck of the genus '' Bucephala'', the goldeneyes. This bird was named after Sir John Barrow. The genus name is derived from Ancient Greek ''boukephalos'', "bullheaded", from ''bous'', "bull " and ''kephale'', "head", a reference to the bulbous head shape of the bufflehead. The species name ''islandica'' means Iceland. Taxonomy Barrow's goldeneye 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 with the ducks, geese and swans in the genus ''Anas'' and coined the binomial name ''Anas islandica''. Gmelin based his description on the "Hravn Oend" that had been briefly described in 1776 by Danish naturalist Otto Friedrich Müller. Barrow's goldeneye is now placed with the common goldeneye and the bufflehead in the genus '' Bucephala'' that was introduced in 1858 by American naturalist Spencer Baird. ...

Ducks Unlimited
Ducks Unlimited (DU) is an American nonprofit organization 501(c) dedicated to the conservation of wetlands and associated upland habitats for waterfowl, other wildlife, and people. It has had a membership of around 700,000 since January 2013. History and profile In 1927, an offshoot of the Boone and Crockett Club was created specifically for sport bird management and operated until 1930 as the American Wild Fowlers. Membership included such people as Arthur Bartley and Nash Buckingham, who would later be involved in the conservation movement. In 1930, Joseph P. Knapp, a publishing tycoon who successfully obtained such notable publications as ''The Associated Sunday Magazine'', Crowell Publishing Company, ''Collier’s Weekly'', ''Farm and Fireside,'' and the book publisher P.F. Collier & Sons, founded More Game Birds in America and American Wild Fowlers was quickly absorbed into the new organization. In 1937, Knapp, Robert Winthrop, E.H.Low and a small group of conservation phi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birds Of Iceland
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the 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 loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Birds ...

Bucephala (bird)
''Bucephala'' is a genus of diving ducks found in the Northern Hemisphere. Taxonomy The genus ''Bucephala'' was introduced in 1858 by American naturalist Spencer Baird with the bufflehead as the type species. The genus name is derived from Ancient Greek ''boukephalos'', meaning "bullheaded", from ''bous'' "bull", and ''kephale'', "head", a reference to the crest of the bufflehead making its head look large. The bufflehead was formerly treated as the only member of the genus (sometimes unnecessarily changed to ''Charitonetta'') while the goldeneyes were incorrectly placed in ''Clangula'' (as ''Clangula americana''), the genus of the long-tailed duck, which at that time was placed in '' Harelda''.Report of the National conference on utilization of forest products.

Exxon Valdez Oil Spill
The ''Exxon Valdez'' oil spill occurred in Prince William Sound, Alaska, on March 24, 1989. ''Exxon Valdez'', an oil supertanker owned by Exxon Shipping Company bound for Long Beach, California struck Prince William Sound's Bligh Reef, west of Tatitlek, Alaska at 12:04 a.m. and spilled (or 37,000 tonnes) of crude oil over the next few days. The ''Exxon Valdez'' spill is the second largest in U.S. waters, after the 2010 ''Deepwater Horizon'' oil spill, in terms of volume of oil released. Prince William Sound's remote location, accessible only by helicopter, plane, or boat, made government and industry response efforts difficult and made existing response plans especially hard to implement. The region is a habitat for salmon, sea otters, seals, and seabirds. The oil, extracted from the Prudhoe Bay Oil Field, eventually affected of coastline, of which were heavily or moderately oiled.

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east.

Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scottish Ornithologists' Club
The Scottish Ornithologists' Club (SOC) is a Scottish ornithological body, founded in March 1936 at the premises of the Royal Scottish Geographical Society. As of 2008, the SOC has 2,200 members. The Club runs the Scottish Birds Records Committee, which maintains a list of birds recorded in Scotland. In 2007, the club was awarded the Silver Medal by the Zoological Society of London.

Mývatn
() is a shallow lake situated in an area of active volcanism in the north of Iceland, not far from Krafla volcano. It has a high amount of biological activity. The lake and the surrounding wetlands provides a habitat for a number of waterbirds, especially ducks. The lake was created by a large basaltic lava eruption 2300 years ago, and the surrounding landscape is dominated by volcanic landforms, including lava pillars and rootless vents (pseudocraters). The effluent river is known for its rich fishing for brown trout and Atlantic salmon. The name of the lake ( Icelandic ("midge") and ("lake"); "the lake of midges") comes from the large numbers of midges present in the summer. The name is sometimes used not only for the lake but the whole surrounding inhabited area. The river , the lake and the surrounding wetlands are protected as a nature reserve (the – Nature Conservation Area, which occupies ). Since the year 2000, a marathon around the lake takes place in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
