It sees itself as an association of German-language owl experts. In addition to individuals, membership is open to groups, clubs, associations and institutions. The nature and species protection work of the OWG is based on the gathering, evaluation and dissemination of knowledge and experience regarding the biology and protection of owls. For each species of owl occurring in Germany there is a species specialist and for each federal state there is a state representative. Every year, the OWG organises a meeting at different locations, mostly in Germany , in cooperation with local associations or groups.

It includes a protected area called Owl Mountains Landscape Park. Seen from the Silesian Lowlands in the northeast, the Owl Mountains form a comparatively steep edge of the Central Sudetes, though the range is very diversified in terms of height. The highest peaks are Wielka Sowa "Great Owl", at 1, m 3, ft in altitude and Kalenica m 3, ft with their observation towers. Other peaks reach heights from about m 2, ft to m 3, ft metres above sea level. The Precambrian gneiss rocks of the Owl Mountains constitute the oldest part of the Sudetes and are among the oldest in Europe. Other deposits include migmatite rocks, to a lesser extent also amphibolite , serpentinite , granulite , and pegmatite. Except for the summit clearings and the mountain passes, the Owl Mountains represent the spruce-clad type of mountains. There may be also observed a rare natural occurrence of beeches and European yew. Parts of the extended complex are accessible and can be visited as part of a guided tour. The mountains are covered by a network of tourist trails, including the "red trail", leading through most of Europe. Contents move to sidebar hide. Article Talk.

Owls are divided into two families : the true or typical owl family, Strigidae, and the barn-owl family, Tytonidae. They are found in all regions of the Earth except the polar ice caps and some remote islands. A group of owls is called a "parliament". 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.

Bereits im antiken Rom glaubten viele, dass der Eulenruf den nahen Tod eines Menschen voraussagt. Diesen Ruf haben die Eulen lange nicht verloren. Noch im Ihre Augen sind sehr viel lichtempfindlicher als die des Menschen. Diesen Nachteil gleicht die Eule aber durch eine enorme Beweglichkeit des Kopfes aus. Sie vollbringt dabei eine Drehung von Grad.

Euler's formula , named after Leonhard Euler , is a mathematical formula in complex analysis that establishes the fundamental relationship between the trigonometric functions and the complex exponential function. Euler's formula states that, for any real number x , one has. Euler's formula is ubiquitous in mathematics, physics, chemistry, and engineering.
