Field signs. It is similar to the big-eared owl, but painting yellower, ears hardly they are noticeable. Back ocherous- brown, bottom is brighter without the transverse shading - only with the longitudinal speckles. Flight leisurely, which is rocked, above earth itself. Current flight with the banging is wing. Little it is careful, especially on the flight. It frequently flies in the daytime. Hunting begins with the first with twilights. In flight a little it resembles paleness. In contrast to other owls (except white), on the trees almost never it sits down itself (willingly it sits down to the colas, the poles), it passes the night and it rests on the earth. Voice - number of the being risen sounds of [bu]-[bu]-[bu]-[bub] and the cry of [kyav]-[kyav] ([Syroechkovskiy], [Rogacheva], 1980). Propagation. It dwells in the open landscapes, preferring the floodlands of rivers, meadow, swamp, the coast of lakes, agricultural land. In average Siberia it is extended very widely and it can be considered as the most usual of Sov. northern populations they are migratory, in the southern part of the edge of bird they roam and even they are settled. It is very usual and by places it is numerous in wooded plain and steppes of south and central regions of edge, but it does not go in the taiga Of [sayan]. In [podtayge] it is also very usual. In the southern and average taiga it is usual up to s. Verkhne-Imbatskoye in the Yenisey (north of central-taiga subzone), but, avoiding scaffolding, it is held mainly on the valleys of large rivers, in lakes and on the swamps. In the northern taiga even in the suitable localities it is encountered more rarely, while in the extreme northern taiga it is definitely rare, even in the valley of the Yenisey ([Angutikha]). At the edge of taiga and in the northern sparse growths ([Khantayskoe] lake, Noril'sk lakes) rarely it nests as in the zone forest-tundra transition area ([Rogacheva], 1988). The single cases of nesting are known even for the southern tundra - on [Pyasine], near the mouth Of [agapy] ([Krechmar], 1966). In the tundra it, obviously, leaves only along the river valleys with the osier beds. In the Yenisey it is noted to Dudinka, in Taimyr - to [Boganidy] ([Middendorf], 1869). Phenology. Flying away from the north is late - to the end of September - the beginning of October ([Syroechkovskiy], [Rogacheva], 1980). Multiplication. It nests on the earth, arranging nest from the dry grass, frequently under the bush, in the forest-tundra transition area - on the hummock among the moss, the lichens and [ernika]. In laying 4-6, while in the years of the abundance of food to ten white eggs. There are repeated layings in the years of the harvest of mouse-like rodents. Jack cycle under Krasnoyarsk of the same as in big-eared owl. In Norilsk on July 8 in the nest was the strongly long occupied eggs, and in the second-half of August the well flying taking out ([Syroechkovskiy], [Rogacheva], 1980). Nourishment. It feeds in essence by mouse-like rodents, on the north - lemmings. The number of owls in mouse years sharply increases. In the years of the small number of rodents it frequently eats up small birds (snipe, snow-buntings and others). More frequent than other owls becomes the victim of [teterevyatnikov] and large Sokolov ([Syroechkovskiy], [Rogacheva], 1980). |
