Cape Parry
Cape Parry is a headland in Canada's Northwest Territories. Located at the northern tip of the Parry Peninsula, it projects into Amundsen Gulf. The nearest settlement is Paulatuk, to the south, and Fiji Island is located to the west. Cape Parry was formerly accessible through Cape Parry Airport that was located at the Distant Early Warning Line. The airport was listed as abandoned after the closure of the DEW line site. It is named for the Arctic explorer William Edward Parry. History Between the 1950s to the 1980s, a Distant Early Warning Line site (PIN-Main, ) was located south of Police Point, the cape's western point. During the period of 1969 to 1982, eighteen sounding rocket launches were made at Cape Parry. Geography Cape Parry is a three-pointed outcrop of coastal cliffs. The limestone formation rises above sea level. The deeply incised coastal beaches are composed of sand and gravel, and form bays and inlets. On either side of the narrow isthmus that joins Cape ...

Headland
A headland, also known as a head, is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. It is a type of promontory. A headland of considerable size often is called a cape.Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984, pp. 80, 246. . Headlands are characterised by high, breaking waves, rocky shores, intense erosion, and steep sea cliff. Headlands and bays are often found on the same coastline. A bay is flanked by land on three sides, whereas a headland is flanked by water on three sides. Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Bays form when weak (less resistant) rocks (such as sands and clays) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk, limestone, and granite) forming a headland, or peninsula. Through the deposition of sediment within the bay and the erosion of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caribou
Reindeer (in North American English, known as caribou if wild and ''reindeer'' if domesticated) are deer in the genus ''Rangifer''. For the last few decades, reindeer were assigned to one species, ''Rangifer tarandus'', with about 10 subspecies. A 2022 revision of the genus elevated five of the subspecies to species (see Taxonomy below). They have a circumpolar distribution and are native to the Arctic, sub-Arctic, tundra, boreal forest, and mountainous regions of northern Europe, Siberia, and North America. Reindeer occur in both migratory and sedentary populations, and their herd sizes vary greatly in different regions. The tundra subspecies are adapted for extreme cold, and some are adapted for long-distance migration. Reindeer vary greatly in size and color from the smallest species, the Svalbard reindeer (''R. t. platyrhynchus''), to the largest subspecies, Osborn's caribou (''R. t. osborni''). Although reindeer are quite numerous, some species and subspecies are in d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Important Bird Areas Of The Northwest Territories
Importance is a property of entities that matter or make a difference. For example, World War II was an important event and Albert Einstein was an important person because of how they affected the world. There are disagreements in the academic literature about what type of difference is required. According to the causal impact view, something is important if it has a big causal impact on the world. This view is rejected by various theorists, who insist that an additional aspect is required: that the impact in question makes a value difference. This is often understood in terms of how the important thing affects the well-being of people. So on this view, World War II was important, not just because it brought about many wide-ranging changes but because these changes had severe negative impacts on the well-being of the people involved. The difference in question is usually understood counterfactually as the contrast between how the world actually is and how the world would have bee ...

Peninsulas Of The Northwest Territories
A peninsula (; ) is a landform that extends from a mainland and is surrounded by water on most, but not all of its borders. A peninsula is also sometimes defined as a piece of land bordered by water on three of its sides. Peninsulas exist on all continents. The size of a peninsula can range from tiny to very large. The largest peninsula in the world is the Arabian Peninsula. Peninsulas form due to a variety of causes. Etymology Peninsula derives , which is translated as 'peninsula'. itself was derived , or together, 'almost an island'. The word entered English in the 16th century. Definitions A peninsula is usually defined as a piece of land surrounded on most, but not all sides, but is sometimes instead defined as a piece of land bordered by water on three of its sides. A peninsula may be bordered by more than one body of water, and the body of water does not have to be an ocean or a sea. A piece of land on a very tight river bend or one between two rivers is sometimes s ... [...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. History In 1985, following a specific request from the European Economic Community, Birdlife International ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uria
''Uria'' is a genus of seabirds in the auk family known in Britain as guillemots, in most of North America as murres, and in Newfoundland and Labrador as turr. These are medium-sized birds with mainly brown or black plumage in the breeding season. They breed on the coasts of the northern Atlantic and Pacific oceans. Taxonomy The genus ''Uria'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the common murre (''Uria aalge'') as the type species. The genus name is from Ancient Greek ''ouria'', a waterbird mentioned by Athenaeus. The English "guillemot" is from French ''guillemot'' probably derived from ''Guillaume'', "William". "Murre" is of uncertain origins, but may imitate the call of the common guillemot. ''Uria'' auks are relatives of the razorbill, little auk and the extinct great auk and together make up the tribe Alcini. Despite the similar British common names, they are not so closely related to the ''Cepphus'' guillemots, which form the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thick-billed Murre
The thick-billed murre or Brünnich's guillemot (''Uria lomvia'') is a bird in the auk family (Alcidae). This bird is named after the Danish zoologist Morten Thrane Brünnich. The very deeply black North Pacific subspecies ''Uria lomvia arra'' is also called Pallas' murre after its describer. The genus name is from Ancient Greek ''ouria'', a waterbird mentioned by Athenaeus. The species term ''lomvia'' is a Swedish word for an auk or diver. The English "guillemot" is from French ''guillemot'' probably derived from ''Guillaume'', "William". "Murre" is of uncertain origins, but may imitate the call of the common guillemot. Murres have the highest flight cost, for their body size, of any animal. Description Since the extinction of the great auk in the mid-19th century, the murres are the largest living members of the Alcidae.Nettleship (1996) The thick-billed murre and the closely related common guillemot (or common murre, ''U. aalge'') are similarly sized, but the thick-billed ...

Black Guillemot
The black guillemot or tystie (''Cepphus grylle'') is a medium-sized seabird of the Alcidae family, native throughout northern Atlantic coasts and eastern North American coasts. It is resident in much of its range, but large populations from the high arctic migrate southwards in winter. The bird can be seen in and around its breeding habitat of rocky shores, cliffs and islands in single or smalls groups of pairs. They feed mainly by diving towards the sea floor feeding on fish, crustaceans or other benthic invertebrates. They are listed on the IUCN red list as a species of least concern. Both sexes have very similar appearances with black plumage and a large white patch on the upper side of their wings in summer. The bill is also black, being rather long and slender, while the feet are coral-red. In winter adult underparts are white and the upperparts are a pale grey with the back and shoulders exhibiting barred light grey and white patterning. The birds breed in solitary pairs o ...

Yellow-billed Loon
The yellow-billed loon (''Gavia adamsii''), also known as the white-billed diver, is the largest member of the loon or diver family. Breeding adults have a black head, white underparts and chequered black-and-white mantle. Non-breeding plumage is drabber with the chin and foreneck white. Its main distinguishing feature is the long straw-yellow bill which, because the culmen is straight, appears slightly uptilted. It breeds in the Arctic and winters mainly at sea along the coasts of the northern Pacific Ocean and northwestern Norway; it also sometimes overwinters on large inland lakes. It occasionally strays well south of its normal wintering range, and has been recorded as a vagrant in more than 22 countries. This species, like all divers, is a specialist fish-eater, catching its prey underwater. Its call is an eerie wailing, lower pitched than the common loon. Taxonomy and etymology First described by English zoologist George Robert Gray in 1859 based on a specimen collected ... [...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 ...

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] |
Glaucous Gull
The glaucous gull (''Larus hyperboreus'') is a large gull, the second-largest gull in the world. It breeds in Arctic regions of the Northern Hemisphere and winters south to shores of the Holarctic. The genus name is from Latin ''larus'', which appears to have referred to a gull or other large seabird. The specific name ''hyperboreus'' is Latin for "northern" from the Ancient Greek ''Huperboreoi'' people from the far north "Glaucous" is from Latin ''glaucus'' and denotes the grey colour of the gull. An older English name for this species is burgomaster. This gull is migratory, wintering from in the North Atlantic and North Pacific Oceans as far south as the British Isles and northernmost states of the United States, also on the Great Lakes. A few birds sometimes reach the southern USA and northern Mexico. Description This is a large and powerful gull, second-largest of all gull species and very pale in all plumage, with no black on either the wings or the tail. Adults are pal ...
