alberta temperature in winter

[17] Like all owls, Eurasian eagle-owls do not build nests or add material but nest on the surface or material already present. In Germany, the eagle-owl can be found in large but highly discontinuous areas, mostly in the south and central areas but is almost entirely absent in areas such as Brandenburg. Peterson, R. T., Mountfort, G., & Hollom, P. A. D. (2001). [6] While sibling owls are close in the stage between leaving the nest and fully fledged, about 20 days after leaving the nest, the family unit seems to dissolve and the young disperse quickly and directly. Farther north, they are found sporadically and discontinuously in Luxembourg, southern and western Belgium and scarcely into the Netherlands. [8], Vocal activity is almost entirely confined to the colder months from late fall through winter, with vocal activity in October through December mainly having territorial purposes and from January to February being primarily oriented towards courtship and mating purposes. [4][6][22] Females can weigh from 1.75 to 4.6 kg (3.9 to 10.1 lb) and males can weigh from 1.22 to 3.2 kg (2.7 to 7.1 lb). [17][98] Tree holes being used for nesting sites are even more rarely recorded than nests constructed by other birds. Based on an extensive fossil record and a central distribution of extant species on that continent, the Bubo appears to have evolved into existence in Africa, although early radiations seem to branch from southern Asia as well. [6], The eggs are normally laid at intervals of three days and are incubated only by the female. König, C., Heidrich, P. & Wink, M. (1996). [17] Essentially, Eurasian eagle-owls have been found living in almost every climatic and environmental condition on the Eurasian continent, excluding the greatest extremities, i.e. Mean clutch size averages 2.02–2.14 in Spain and the massifs of France, 1.82 to 1.89 in central Europe and the eastern Alps; in Sweden and Finland the clutch size averages 1.56 and 1.87, respectively. As the biggest of all the Owls the Eagle owl is easily recognised by its huge size and wingspan. Some reportages of eagle-owls in Britain have been revealed to actually be great horned owls or Indian eagle-owls, the latter a particularly popular owl in falconry circuits. This was particularly true in the Italian Alps, where the number of dangerous, non-insulated pylons near nests was extremely high, but is highly problematic almost throughout the species’ European distribution. [31] Other than general morphology, the above features differ markedly from those of two of the next largest subarctic owl species in Europe and western Asia, which are the great grey owl and the greyish to chocolate-brown Ural owl (Strix uralensis), both of which have no ear tufts and have a distinctly rounded head, rather than the blocky shape of the eagle-owl’s head. Examples of this including northern Germany in 1830, the Netherlands sometimes in the late nineteenth century, Luxembourg in 1903, Belgium in 1943 and central and western Germany in the 1960s. [129][130], While the eagle-owl remains reasonably numerous in some parts of its habitat where nature is still relatively little disturbed by human activity, such as the sparsely populated regions of Russia and Scandinavia, concern has been expressed about the future of the Eurasian eagle-owl in western and central Europe. That would be … [6][20] The average number of eggs laid varies with latitude in Europe. A., & Bourso-Leland, N. (1984). Penteriani, V., Delgado, M. M. (2010) "Búho real –. Therefore, Spanish conservationists have recommended to boost education and stewardship programs in order to protect eagle-owls from direct killing by local residents. Predominantly their diet is comprised by small mammals such as rodents and rabbits and their kin but also they will not infrequently prey on larger mammals and birds of varying sizes. [131], Large reintroduction programs were instituted in Germany after the eagle-owl was deemed extinct in the country as a breeding species by the 1960s, as a result of a long period of heavy persecution.
