Brunnich's Guillemot
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 ...

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...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 ...

Herald Island (Arctic)
Herald Island (, ''Ostrov Gerald'') is a small, isolated Russian island in the Chukchi Sea, east of Waring Point, Wrangel Island.

The only bit of accessible shoreline is at its northwestern point, where the cliffs have crumbled into piles of loose rocks and gravel. Its area is and the maximum height above sea level is . The island is unglaciated and uninhabited. It is the northeasternmost point of land in the world. Herald Island belongs administratively to the Chukotka Autonomous Okrug of the Russian Federation. Along with Wrangel Island, Herald Island has been part of the Wrangel Island Wildlife Preserve, a Russian National Park, since 1976.

Wrangel Island
Wrangel Island (, ; , , ) is an island of the Chukotka Autonomous Okrug, Russia. It is the List of islands by area, 92nd-largest island in the world and roughly the size of Crete. Located in the Arctic Ocean between the Chukchi Sea and East Siberian Sea, the island lies astride the 180th meridian, 180th meridian (geography), meridian. The International Date Line is therefore displaced eastwards at this latitude to keep the island, as well as the Chukchi Peninsula on the Russian mainland, on the same day as the rest of Russia. The closest land to Wrangel Island is the tiny and rocky Herald Island (Arctic), Herald Island located to the east.Kosko, M.K., M.P. Cecile, J.C. Harrison, V.G. Ganelin, N.V., Khandoshko, and B.G.

New Siberian Islands
The New Siberian Islands (; ) are an archipelago in the Extreme North of Russia, to the north of the East Siberian coast between the Laptev Sea and the East Siberian Sea north of the Sakha (Yakutia) Republic, of whose Bulunsky District they are administratively a part.

Vagin reached the Great Lyakhovsky Island. In 1809–10 Yakov Sannikov and Matvei Gedenschtrom went to the New Siberian Islands on a cartographic expedition. Sannikov reported the sighting of a "new land" north of Kotelny in 1811. This became the myth of ''Zemlya Sannikova'' or '' Sannikov Land''.Markham, Albert Hastings ''Arctic Exploration'', 1895 In 1886, Russian polar explorer and scientist Eduard Toll, during his first visit to the New Siberian Islands, thought that he had seen an unknown land north of Kotelny Island.

Loon
Loons (North American English) or divers (British English, British / Irish English) are a group of aquatic birds found in much of North America and northern Eurasia. All living species of loons are members of the genus ''Gavia'', family (biology), family Gaviidae and order (biology), order Gaviiformes. Description Loons, which are the size of large ducks or small goose, geese, resemble these birds in shape when swimming. Like ducks and geese, but unlike coots (which are Rallidae) and grebes (Podicipedidae), the loon's toes are connected by Bird feet and legs#Webbing and lobation, webbing. The loons may be confused with the cormorants (Phalacrocoracidae), but can be distinguished from them by their distinct call. Cormorants are not-too-distant relatives of loons, and like them are heavy-set birds whose bellies, unlike those of ducks and geese, are submerged when swimming. Loons in flight resemble plump geese with seagulls' wings that are relatively small in proportion to their bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Athenaeus
Athenaeus of Naucratis (, or Nαυκράτιος, ''Athēnaios Naukratitēs'' or ''Naukratios''; ) was an ancient Greek rhetorician and Grammarian (Greco-Roman), grammarian, flourishing about the end of the 2nd and beginning of the 3rd century AD. The ''Suda'' says only that he lived in the times of Marcus Aurelius, but the contempt with which he speaks of Commodus, who died in 192, implies that he survived that emperor. He was a contemporary of Adrantus. Athenaeus himself states that he was the author of a treatise on the ''thratta'', a type of fish mentioned by Archippus (poet), Archippus and other comic poets, and of a history of the Syrian kings. Both works are lost. Of his works, only the fifteen-volume ''Deipnosophistae'' mostly survives. The ''Deipnosophistae'' The ''Deipnosophistae'', which means 'dinner-table philosophers', survives in fifteen books.
