Great Plain Of The Koukdjuak
The Great Plain of the Koukdjuak is located in the Qikiqtaaluk Region, Nunavut within the Canadian Arctic. It is the namesake of the Koukdjuak River in western Baffin Island on the southeastern coast of Foxe Basin. It stretches from Cory Bay to Hantzsch Bay, and then inland. Geography The plain is about long, wide and has an area of . It is characterized as a broad, flat, water-logged lowland with a tidal zone that may extend as far as inland. The Plain's boundaries include raised beach ridges inland and granite outcrops to the south. Its tundra covers clay soils, limestone and shale bedrock. Fauna It is notable for migratory bird and wildlife (Barren-ground caribou crossing) habitat. The plain supports the largest goose colony in the world. It is a breeding ground or habitat for lesser snow geese, Canada geese, long-tailed ducks, king eider, common eider, and Atlantic brant. It is a natural habitat for shorebirds, such as the red phalarope. It is classified as an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Barren-ground Caribou
The barren-ground caribou (''Rangifer tarandus groenlandicus''; but subject to a recent taxonomic revision. See Reindeer: Taxomony.) is a subspecies of the reindeer (or the caribou in North America) that is found in the Canadian territories of Nunavut and the Northwest Territories, in northern Alaska and in south-western, Greenland. It includes the Porcupine caribou of Yukon and Alaska.Cronin, M. A., M. D. Macneil, and J. C. Patton (2005). ''Variation in Mitochondrial DNA and Microsatellite DNA in caribou (Rangifer tarandus) in North America.'' Journal of Mammalogy 86(3): 495–505. The barren-ground caribou is a medium-sized caribou, smaller and lighter-colored than the boreal woodland caribou, with the females weighing around and the males around . However, on some of the smaller islands, the average weight may be less. The large migratory herds of barren-ground caribou take their names from the traditional calving grounds, such as the Ahiak herd, the Baffin Island herds, ...

Dewey Soper Migratory Bird Sanctuary
Dewey Soper Migratory Bird Sanctuary, or Dewey Soper, is a migratory bird sanctuary in the Qikiqtaaluk Region, Nunavut, Canada. It is located in western Baffin Island, from Bowman Bay to the Koukdjuak River, and is named in honour of zoologist J. Dewey Soper. It is an area that was classified a wetland of international importance via the Ramsar Convention on May 24, 1982. The bird sanctuary supports nearly 30% of the breeding geese in Canada, making it the largest goose colony in the world. Up to two million birds of various species use the area for summer nesting, and it is also "habitat for one of Canada's major barren-ground caribou herds". The sanctuary was established in 1957, and is subject to the Nunavut Land Claims Agreement, which defines and governs ownership, land use and hunting rights in the area . It is an intertidal zone on a broad coastal plain with raised, slightly sloping beaches, spotted with circular shallow lakes and a marsh A marsh is a wetland t ...

Key Habitat Site
A Key Habitat Site is a Canadian Wildlife Service designation for an area that supports at least 1% of the country's population of any migratory bird species, or subspecies, at any time. There may be overlap with areas designated as a migratory bird sanctuary or National Wildlife Area A National Wildlife Area is a conservation designation for a geographical region in Canada that restricts most human activities on that region. However, land use permits may be issued "for activities that are compatible with conservation". Suc ....

International Biological Program
The International Biological Program (IBP) was an effort between 1964 and 1974 to coordinate large-scale ecological and environmental studies. Organized in the wake of the successful International Geophysical Year (IGY) of 1957-1958, the International Biological Program was an attempt to apply the methods of big science to ecosystem ecology and pressing environmental issues. The IBP was organized under the leadership of C. H. Waddington beginning in 1962 and officially started in 1964, with the goal of exploring "The Biological Basis of Productivity and Human Welfare". In its early years, Canadian and European ecologists were the main participants; by 1968, the United States also became heavily involved. However, unlike other more successful applications of the big science model of scientific research, the IBP lacked a clear, socially and scientifically pressing goal. Many biologists, particularly molecular biologists and evolutionary ecologists, were sharply critical of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Shorebirds
245px, A flock of Dunlins and Red knots">Red_knot.html" ;"title="Dunlins and Red knot">Dunlins and Red knots Waders or shorebirds are birds of the order Charadriiformes commonly found wikt:wade#Etymology 1, wading along shorelines and mudflats in order to foraging, forage for food crawling or burrowing in the mud and sand, usually small arthropods such as aquatic insects or crustaceans. The term "wader" is used in Europe, while "shorebird" is used in North America, where "wader" may be used instead to refer to long-legged wading birds such as storks and herons. There are about 210 species of wader, most of which live in wetland or coastal environments. Many species of Arctic and temperate regions are strongly migratory, but tropical birds are often resident, or move only in response to rainfall patterns. Some of the Arctic species, such as the little stint, are amongst the longest distance migrants, spending the non- breeding season in the southern hemisphere. Many of the s ...

Brant Goose
The brant or brent goose (''Branta bernicla'') is a small goose of the genus ''Branta''. There are three subspecies, all of which winter along temperate-zone sea-coasts and breed on the high-Arctic tundra. The Brent oilfield was named after the species. Description The brant is a small goose with a short, stubby bill. It measures long, across the wings and weighs . The under-tail is pure white, and the tail black and very short (the shortest of any goose). The species is divided into three subspecies: * Dark-bellied brant goose ''B. b. bernicla'' (Linnaeus, 1758) * Pale-bellied brant goose ''B. b. hrota'' ( Müller, 1776) (also known as light-bellied brent goose in Europe, and Atlantic brant in North America) * Black brant goose ''B. b. nigricans'' (Lawrence, 1846) (sometimes also known as the Pacific brant in North America) Some DNA evidence suggests that these forms are genetically distinct; while a split into three separate species has been proposed, it is not wide ...

Common Eider
The common eider (pronounced ) (''Somateria mollissima''), also called St. Cuthbert's duck or Cuddy's duck, is a large ( in body length) sea-duck that is distributed over the northern coasts of Europe, North America and eastern Siberia. It breeds in Arctic and some northern temperate regions, but winters somewhat farther south in temperate zones, when it can form large flocks on coastal waters. It can fly at speeds up to . The eider's nest is built close to the sea and is lined with eiderdown, plucked from the female's breast. This soft and warm lining has long been harvested for filling pillows and quilts, but in more recent years has been largely replaced by down from domestic farm-geese and synthetic alternatives. Although eiderdown pillows or quilts are now a rarity, eiderdown harvesting continues and is sustainable, as it can be done after the ducklings leave the nest with no harm to the birds. Taxonomy The common eider was formally named by the Swedish naturalist Carl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
King Eider
The king eider (pronounced ) (''Somateria spectabilis'') is a large sea duck that breeds along Northern Hemisphere Arctic coasts of northeast Europe, North America and Asia. The birds spend most of the year in coastal marine ecosystems at high latitudes, and migrate to Arctic tundra to breed in June and July. They lay four to seven eggs in a scrape on the ground lined with grass and down. Taxonomy and etymology When he first described the king eider in 1758, in the 10th edition of his opus Systema Naturae, Carl Linnaeus assigned it to the genus ''Anas'', along with the rest of the ducks. In 1819, William Elford Leach moved it and the other large eiders to the genus ''Somateria'', where it has remained since. It is very closely related to the other members of its genus, and is known to hybridise with the common eider. Despite its very large range, it is monotypic. The genus name ''Somateria'' is a combination of the Greek words ''sōma'', meaning "body", and ''erion'', meanin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long-tailed Duck
The long-tailed duck (''Clangula hyemalis''), formerly known as oldsquaw, is a medium-sized sea duck that breeds in the tundra and taiga regions of the arctic and winters along the northern coastlines of the Atlantic and Pacific Oceans. It is the only member of the genus ''Clangula''. Taxonomy The long-tailed duck was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae''. He placed it with all the other ducks in the genus ''Anas'' and coined the binomial name ''Anas hyemalis''. Linnaeus cited the English naturalist George Edwards's description and illustration of the "Long-tailed duck from Hudson's-Bay" that had been published in 1750 in the third volume of his ''A Natural History of Uncommon Birds''. This duck is now the only species placed in the genus ''Clangula'' that was introduced in 1819 to accommodate the long-tailed duck by the English zoologist William Leach in an appendix to John Ross's account of his vo ...
