Aegolius
''Aegolius'' is a genus of small true owls. The genus name is from Latin, ''aegolius'', is a type of screech owl that was thought to be a bird of ill omen. Taxonomy The genus ''Aegolius'' was introduced in 1829 by the German naturalist Johann Jakob Kaup with the boreal owl (''Aegolius funereus'') as the type species. The genus name is Latin for a screech owl, the word came from the Ancient Greek ''aigōlios'' meaning "a bird of ill omen". In Greek mythology, Aegolius (mythology), Aegolius was originally a man whom Zeus transformed into an owl. Species The genus contains five species: * Boreal owl or Tengmalm's owl, ''Aegolius funereus'' * Northern saw-whet owl, ''Aegolius acadicus'' *† Bermuda saw-whet owl, ''Aegolius gradyi'' (extinct) * Unspotted saw-whet owl, ''Aegolius ridgwayi'' * Buff-fronted owl, ''Aegolius harrisii'' Description ''Aegolius'' owls are small, stout, short-tailed, and broad-winged, with large, round facial discs. The species varies from 18 to 27 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boreal Owl
The boreal owl or Tengmalm's owl (''Aegolius funereus'') is a small owl in the "true owl" family Strigidae. It is known as the boreal owl in North America and as Tengmalm's owl in Europe after Swedish naturalist Peter Gustaf Tengmalm or, more rarely, Richardson's owl after Sir John Richardson. Due to the boreal owl's shyness and evasive reaction to human activities, nocturnal habits and preferred inaccessible taiga forest habitat, it is rarely seen by humans. Taxonomy The boreal owl was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae''. Linnaeus placed it with all the other owls in the genus ''Strix'' and coined the binomial name ''Strix funerea''. The Eurasian scops owl is now placed in the genus ''Aegolius'' that was introduced in 1829 by the German naturalist Johann Jakob Kaup with the boreal owl as the type species. The genus name is Latin for a screech owl, the word came from the Ancient Greek ''aigōlios' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Northern Saw-whet Owl
The northern saw-whet owl (''Aegolius acadicus'') is a species of small owl in the family Strigidae. The species is native to North America. Saw-whet owls of the genus ''Aegolius'' are some of the smallest owl species in North America. They can be found in dense thickets, often at eye level, although they can also be found some up. Saw-whets are often in danger of being preyed upon by larger birds of prey. The northern saw-whet owl is a migratory bird without any strict pattern. Taxonomy The northern saw-whet owl was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the other owls in the genus ''Strix'' and coined the binomial name ''Strix acadicus''. Gmelin based his description on the "Acadian owl" from Nova Scotia that had been described and illustrated in 1781 by the English ornithologist John Latham in his multi-volume work ''A General Synopsis of Birds'' ...

Bermuda Saw-whet Owl
The Bermuda saw-whet owl (''Aegolius gradyi'') was a species of owl that was endemic to Bermuda. It was described from fossil records and explorer accounts of the bird in the 17th century. The cause of its extinct Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and ...ion is unknown, but it may have been related to the decline of cedar and palmetto trees, or the arrival of non-native predators and competitors after human colonization. First described in 2012, it was declared extinct in 2014 (though the extinction itself was in the 17th century).

Aegolius (mythology)
In Greek mythology, Aegolius ( grc, Αἰγωλιός, Aigо̄liós) is a Cretan man who attempted to steal from Zeus, the king of gods, and was punished for it. He was transformed into an owl. Mythology The Cretan Aegolius and three other men, Cerberus, Celeus and Laius entered the sacred cave of Zeus in Crete where the young god had been born and brought up with the aim to steal some of the sacred honey produced by Zeus's bee nurses. Zeus thundered and stripped them of their brazen armors. He meant to kill them all, but Themis and the Moirai advised him against that, as the cave was a holy place and no one should be killed in it. So Zeus turned them all into birds instead; Aegolius became an ''aegolius'' owl.Smith, s.vLaius 2/ref> See also * Pandareus * Tantalus * Pyrrhus References Bibliography * Antoninus Liberalis, ''The Metamorphoses of Antoninus Liberalis'' translated by Francis Celoria (Routledge 1992)Online version at the Topos Text Project.* * * William Sm ...

True Owl
The true owls or typical owls (family Strigidae) are one of the two generally accepted families of owls, the other being the barn owls (Tytonidae). This large family comprises 230 living or recently extinct species in 24 genera. The typical owls have a cosmopolitan distribution and are found on every continent except Antarctica. Morphology While typical owls (hereafter referred to simply as owls) vary greatly in size, with the smallest species, the elf owl, being a hundredth the size of the largest, the Eurasian eagle-owl and Blakiston's fish owl, owls generally share an extremely similar body plan.Marks, J. S.; Cannings, R.J. and Mikkola, H. (1999). "Family Strigidae (Typical Owls)". ''In'' del Hoyo, J.; Elliot, A. & Sargatal, J. (eds.) (1999). '' Handbook of the Birds of the World.

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Alps
The Alps () ; german: Alpen ; it, Alpi ; rm, Alps ; sl, Alpe . are the highest and most extensive mountain range system that lies entirely in Europe, stretching approximately across seven Alpine countries (from west to east): France, Switzerland, Italy, Liechtenstein, Austria, Germany, and Slovenia. The Alpine arch generally extends from Nice on the western Mediterranean to Trieste on the Adriatic and Vienna at the beginning of the Pannonian Basin. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the French–Italian border, and at is the highest mountain in the Alps. The Alpine region area contains 128 peaks higher than .

Eurasia
Eurasia (, ) is the largest continental area on Earth, comprising all of Europe and Asia. Primarily in the Northern and Eastern Hemispheres, it spans from the British Isles and the Iberian Peninsula in the west to the Japanese archipelago and the Russian Far East to the east. The continental landmass is bordered by the Atlantic Ocean and Africa to the west, the Pacific Ocean to the east, the Arctic Ocean to the north, and by Africa, the Mediterranean Sea, and the Indian Ocean to the south. The division between Europe and Asia as two continents is a historical social construct, as many of their borders are over land; thus, in some parts of the world, Eurasia is recognized as the largest of the six, five, or four continents on Earth. In geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on paleomagnetic data. Eurasia covers around , or around 36.2% of the Earth's total land area. It is also home to the largest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
