Owl

Owls are birds from the order Strigiformes, which includes about 200 species of mostly solitary and nocturnal birds of prey typified by an upright stance, a large, broad head, binocular vision, binaural hearing, sharp talons and feathers adapted for silent flight. Exceptions include the diurnal northern hawk-owl and the gregarious burrowing owl.

Owls hunt mostly small mammals, insects, and other birds although a few species specialize in hunting fish. They are found in all regions of the Earth except Antarctica and some remote islands.

Owls are divided into two families: the true owls or typical owls, Strigidae; and the barn-owls, Tytonidae.

Anatomy

Owls possess large forward-facing eyes and ear-holes; a hawk-like beak; a flat face; and usually a conspicuous circle of feathers, a facial disc, around each eye. The feathers making up this disc can be adjusted in order to sharply focus sounds from varying distances onto the owls' asymmetrically placed ear cavities. Most birds of prey have eyes on the sides of their heads, but the stereoscopic nature of the owl's forward-facing eyes permits the greater sense of depth perception necessary for low-light hunting. Although owls have binocular vision, their large eyes are fixed in their sockets—as are those of other birds—so they must turn their entire head to change views. As owls are farsighted, they are unable to see clearly anything within a few centimeters of their eyes. Caught prey can be felt by owls with the use of filoplumes—like feathers on the beak and feet that act as "feelers". Their far vision, particularly in low light, is exceptionally good.

Moscow

Moscow (/ˈmɒskaʊ/ or /ˈmɒskoʊ/; Russian: Москва́, tr. Moskva; IPA: [mɐˈskva]) is the capital and the largest city of Russia, with 12.2 million residents within the city limits and 16.8 million within the urban area. Moscow has the status of a federal city in Russia.

Moscow is a major political, economic, cultural, and scientific center of Russia and Eastern Europe, as well as the largest city entirely on the European continent. By broader definitions Moscow is among the world's largest cities, being the 14th largest metro area, the 17th largest agglomeration, the 16th largest urban area, and the 10th largest by population within city limits worldwide. According to Forbes 2013, Moscow has been ranked as the ninth most expensive city in the world by Mercer and has one of the world's largest urban economies, being ranked as an alpha global city according to the Globalization and World Cities Research Network, and is also one of the fastest growing tourist destinations in the world according to the MasterCard Global Destination Cities Index. Moscow is the northernmost and coldest megacity and metropolis on Earth. It is home to the Ostankino Tower, the tallest free standing structure in Europe; the Federation Tower, the tallest skyscraper in Europe; and the Moscow International Business Center. By its territorial expansion on July 1, 2012 southwest into the Moscow Oblast, the area of the capital more than doubled; from 1,091 square kilometers (421 sq mi) up to 2,511 square kilometers (970 sq mi), and gained an additional population of 233,000 people.
