Field signs. Middle-sized, very dark eagle of monotonous dark-brown painting. Young with the bright speckles. To [nadkhvoste] is whitish. Paws and [voskovitsa] are yellow. Mass of males to 2 kgf, females - about 3 kg. careful bird with the rapid and adroit flight. Besides soaring, much actively flies. Frequently it walks along the earth. Voice - ringing [kyak]-[kyak]-[kyak] .
Places of inhabiting. Rarefied high scaffolding, usually on the proximity with the open sections, the reservoirs or the swamps. It populates in the suitable places of foothills and [nizkogorya] ([Sushkin], 1938). Multiplication. Jack sections are constant, nest are used many years. Nest is arranged on the tree, usually at the height of 8-12 meters, sometimes to 25 meters. Laying more frequently consists of two eggs. On the average To [keti] among the swamps the nest with the complete laying was found on May 14. The nestling in the taking out usually one, young most frequently perishes. Autumnal flying away at the end of September ([Syroechkovskiy], [Rogacheva], 1995; [Syroechkovskiy] and other, 2000). Nourishment. It traces output in flight, but frequently it hunts also on the earth, being sufficient the met animals. It feeds by rodents (from the field voles to the gopher and the hare), birds (weft, heath-cocks, rooks, crows, magpies) and their eggs, nonflying nestlings. It in large quantities eats up frogs, lizards, large insects. At a convenient time eats fish and carrion ([Syroechkovskiy], [Rogacheva], 1995; [Syroechkovskiy] and other, 2000). Number. At the beginning of century in the south of edge it was disseminated sporadically, but by places it was considered usual. In 1940-1950- X years it was already rare ([Yanushevich], [Yurlov], 1950). Now it is everywhere in the edge very rare, and for the Minusinsk basin it is considered as the disappearing form (Prokofiev, 1987). Limiting factors. Region of the inhabiting of large [podorlika] - wooded plain and to [lesopole], the most mastered and changed by man landscapes. In spite of explanatory work among the population, these birds, until now, fire back, and their nests often ruin. It is obvious that on the trophic control path of the toxic chemicals, used in the agriculture, was reflected also in the reproduction of large [podorlika] ([Syroechkovskiy] and other, 2000). It is guarded by hunting legislation, it is carried into the Red Book RF. The penalty is collected for the output of bird or the destruction of nest. Large of [podorlik] is introduced into the appendix OF THE II convention [SITES] and into the enumeration of the Russian- Indian convention about the protection of migratory birds ([Syroechkovskiy] and other, 2000). |
Propagation. It is encountered in the wooded plain and the [lesopolnom] landscape of the south of edge with the significant participation of forest, in essence on the river valleys. On the right bank of the Yenisey it is noted in [podtayge] on r. to Kahn and left tributaries Angara River. On the left shore r. of the Yenisey on by [lesopolyu] it went to the latitude g. it was Yenisey. South rarely it was encountered in the Minusinsk basin, [Khakasii], in the foothill scaffolding Of [sayan]. At present in the forest-steppe sections of Minusinsk basin on the nesting place it is not found (bushes, 1981). As the very rare, but regularly meeting bird it is mentioned for the pond r. Of [chuny] ([Ravkin], 1984). One bird was noted in the 50th years in lower-whaleTSwhom of threshold in the average flow r. Of [kazyr] (Kim, 1961). It is mentioned as the rare form of three groups of the biotopes of Sayan-Shushenskoye preserve, uncharacteristic for this form: mountain steppes, cliffs and scatterings, steppes and meadows on the terraces of the Yenisey. On some information it here nests (Sokolov and other, 1983; Petrov, [Rudkovskiy], 1985), on others - only aestivates ([Syroechkovskiy], [Rogacheva], 1995). Young bird was observed near the sett. Of [usinsk] in The [usinskaya] basin ([Syroechkovskiy], [Bezborodov], 1987). Two pairs of [podorlikov] are noted in wooded plain and [podtayge] Of the [shirinskogo] and [Ordzhonikidzevskogo] regions ([Syroechkovskiy], [Rogacheva], 1995). By us large of [podorlik] was noted by 28.08.97 g. in the environments g. shaggy [Kotur] in the foothills Of the [kosinskogo] ridge ([Bogradskiy] region) ([Baykalov] and other, 1999). On r.
