Uria
''Uria'' is a genus of seabirds in the auk family known in Europe 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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Murre
The common murre or common guillemot (''Uria aalge'') is a large auk. It has a Subarctic, circumpolar distribution, occurring in low-Arctic and boreal waters in the North Atlantic and North Pacific. It spends most of its time at sea, only coming to land to breed on rocky cliff shores or islands. Common murres are fast in direct flight but are not very agile. They are highly mobile underwater using their wings to 'fly' through the water column, where they typically dive to depths of . Depths of up to have been recorded. Common murres breed in Bird colony, colonies at high densities. Nesting pairs may be in bodily contact with their neighbours. They make no nest; their single egg is Avian incubation, incubated between the adult's feet on a bare rock ledge on a cliff face. Eggs hatch after ~30 days incubation. The chick is born Down feather, downy and can regulate its body temperature after 10 days. Some 20 days after hatching, the chick leaves its nesting ledge and heads for the s ...

Uria Lomvia
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. Taxonomy The thick-billed murre was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. He placed it with the other auks in the genus '' Alca'' and coined the binomial name ''Alca lomvia''. Linnaeus specified the type locality as boreal Europe but this was restricted in 1921 to Greenland by the German ornithologist Ernst Hartert. The thick-billed murre is now placed together with the common murre in the genus ''Uria'' that was introduced in 1760 by the French zoologist Mathurin Jacques Brisson. The genus name is from Ancient Greek ''ouria'', a waterbird mentioned by Athenaeus. The specific epithet ''lomvia'' is a Swedish wor ...

Guillemot
Guillemot is the common name for several species of seabird in the Alcidae or auk family, part of the order Charadriiformes. In Europe, the term covers two genera, '' Uria'' and '' Cepphus''. In North America the ''Uria'' species are called murres and only the ''Cepphus'' species are called "guillemots". The current spelling ''guillemot'' is of French origin, first attested by Pierre Belon in 1555, but derived from Old (11th century) French ''willelm'', and matched by English variants ''willock'' (attested 1631), ''willick'', ''will'' and ''wilkie'', all from forms of the name William, cf. , but ultimately onomatopoeic from the loud, high-pitched "''will'', ''willem''" begging calls of the newly fledged young of the common guillemot. The American name ''murre'', also known from England (particularly Cornwall) from the 17th century, is by contrast, onomatopoeic of the growling call of adult common guillemots. The two living species of ''Uria'', together with the razorbill, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monterey Formation
The Monterey Formation is an extensive Miocene oil-rich geology, geological sedimentary formation in California, with outcrops of the formation in parts of the California Coast Ranges, Peninsular Ranges, and on some of California's off-shore islands. The Type locality (geology), type locality is near the city of Monterey, California. The Monterey Formation is the major source-rock for 37 to 38 billion barrels of oil in conventional traps such as sandstones. This is most of California's known oil resources. The Monterey has been extensively investigated and mapped for Hydrocarbon exploration, petroleum potential, and is of major importance for understanding the complex geological history of California. Its rocks are mostly highly siliceous strata that vary greatly in composition, stratigraphy, and Tectonostratigraphy, tectono-stratigraphic history. The US Energy Information Administration (EIA) estimated in 2014 that the 1,750 square mile Monterey Formation could, as a ...

Razorbill
The razorbill (''Alca torda'') is a North Atlantic colonial seabird and the only extant member of the genus ''Alca (bird), Alca'' of the family Alcidae, the auks. It is the closest living relative of the extinct great auk (''Pinguinus impennis''). Historically, it has also been known as "auk", "razor-billed auk" and "lesser auk". Razorbills are primarily black with a white underside. The male and female are identical in plumage; however, males are generally larger than females. This agile bird, which is capable of both flight and diving, has a predominantly aquatic lifestyle and only comes to land in order to breed. It is Monogamy in animals, monogamous, choosing one partner for life. Females lay one egg per year. Razorbills nest along coastal cliffs in enclosed or slightly exposed crevices. The parents spend equal amounts of time incubating, and once the chick has hatched, they take turns foraging for their young. Presently, this species faces major threats, including the dest ...

Great Auk
The great auk (''Pinguinus impennis''), also known as the penguin or garefowl, is an Extinction, extinct species of flightless bird, flightless auk, alcid that first appeared around 400,000 years ago and Bird extinction, became extinct in the mid-19th century. It was the only modern species in the genus ''Pinguinus''. It was not closely related to the Penguin, penguins of the Southern Hemisphere, which were named for their resemblance to this species. It bred on rocky, remote islands with easy access to the ocean and a plentiful food supply, a rarity in nature that provided only a few breeding sites for the great auks. During the non-breeding season, the auk foraged in the waters of the North Atlantic, ranging as far south as northern Spain and along the coastlines of Canada, Greenland, Iceland, the Faroe Islands, Norway, Ireland, and Great Britain. The bird was tall and weighed about , making it the largest alcid to survive into the modern era, and the second-largest member ...

Little Auk
The little auk (Europe) or dovekie (North America) ''Alle alle'' is a small auk, the only member of the genus ''Alle''. ''Alle'' is the Sami name of the long-tailed duck; it is onomatopoeic and imitates the call of the drake duck. Linnaeus was not particularly familiar with the winter plumages of either the auk or the duck, and appears to have confused the two species. Other old names include rotch, rotche, bullbird, and sea dove, although the latter sometimes refers to a relative, the black guillemot. They breed on islands in the high Arctic. There are two subspecies; ''A. a. alle'' breeds in Greenland, Novaya Zemlya and Svalbard; and ''A. a. polaris'' on Franz Josef Land. A small number of individuals Little Diomede Island in the Bering Strait with additional breeding individuals thought to occur on King Island, St. Lawrence Island, St. Matthew Island and the Pribilof Islands in the Bering Sea. They also formerly bred on Grímsey just north of Iceland, but are extinct the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
