[Baloban] Falco of cherug Of gray, 1834 Name of view of other languages
|
Field signs. Large falcon. The mass of male 0,8-0,9 kgf, female 1,0-1,1 kg. it is similar to the gerfalcon, but it seems more ordered. From [sapsana] it in flight differs in terms of large sizes, wider wings and long tail. At a distance adult birds seem brown on top and whitish from below, young - monotonous brown. Meeting in the edge Siberian [baloban] (Falco of cherrug of milvipes Of jerdon, 1871) on the painting is passage from primitive single-tone western subtypes to progressive eastern subtypes, in tail assembly of which is strongly developed transverse figure ([Dementev], 1951). The top of body is characterized by well developed ocherous transverse spots, bottom whitish- ocherous, with the drop-like spots on the belly, in males frequently without the dark figure on the breast. Head is light-khrtrue with dark [nastvolyami]. Besides Siberian [balobana], in the edge is encountered usual [baloban] (Falco of cherrug of cherrug Of gray, 1834), paler and brighter. The dark whiskers , characteristic for [sapsana], in [balobanov] are expressed weakly. Voice - trill in spring, and also usual falcon [kyak]-[kyak]-[kyak] or [keeek]-[keeek] ([Syroechkovskiy], [Rogacheva], 1995).
It is usual in the Minusinsk basin in the region Lake. Small [Kyzykul] and at The [taezhinskiy] hospital (bushes, 1982). Nests were found in Shushenskoe to boron, in the environments of the former [Migninskogo] reservoir of Yermak region, the pair of [balobanov] was encountered on the shore by r. of the Yenisey in the environments s. dark-blue stone, single individuals were noted near s. Of [voznesenki], in the floodlands r. Of [kebezh] in the natural boundary Of [filaretikha] . The nests of [balobanov] are discovered in 1988. on [Oykha] mountain near the sett. [Kuragino], in the environments s. Of [pokrovka] on by right [Kizira] to r. coast, in 7 km lower than mouth r. Of [kizira] on the left shore r. Of [kazyra] ([Karatuzskiy] region) and in 10 km lower than sett. [Kuragino] on r. to tube (Baranov, 1988). Single individuals are noted on by right to the coast r. of the Yenisey lower than mouth r. of Kahn, on The [kizire] rivers, to tube in the region is - [Taskin], [Eferev] and [Kolmakovskiy] ([Valyukh], 1996). Nests [baloban] in the Yenisey part of Western [Sayana] (Sokolov and of others, 1983; Petrov, [Rudkovskiy], 1983), To the [usinskaya] basin, in the environments s. Of [aradan], is encountered on The [kurtushibinskiy] ridge ([Syroechkovskiy] and other, 2000). Places of inhabiting. In the territory of Krasnoyarskiy Kray are extended two subtypes of [balobanov] and their place of inhabiting they have some differences. Paler and light painted usual [baloban] (western part of the area) nests in the plains island scaffolding and the foothill wooded plains. A Siberian subtype, is more dark painted, it prefers the sections of mountain steppes with the perpendicular outputs of cliffs, in the dry mountains in the woodless sections or in the forest-covered mountains with the outputs of cliffs (Yudin, 1952). It does not nest in the mining sections of bald-peaked belt, but it is sufficiently usual here on the hunting, especially after the departure of young.
Limiting factors. The arrangement of the being nested pairs is connected not only with the presence of corresponding [statsiy], but also with the mosaic structure of the distribution of rodents - the basic fodder of [balobana]. Usually within the limits of jack territory the pair of [balobanov] is noted the high density of the settlement of long-tailed gophers or field voles. In their ration are sufficiently usual the birds, especially in the winter period. The depressions of rodents in the separate years, caused by different reasons, lead to the significant fluctuations of number and fruitfulness of [balobana] (Baranov, 1991). Since the long-tailed gopher is one of the most stable forms of rodents in the territory of edge, the state of [balobana] does not cause special fears. Is important for [balobana] the presence of finished jack platforms and corresponding rock formations, necessary for the discarding of eggs. These falcons are very sensitive to the pesticides, utilized for the destruction of rodents. The factor of uneasiness does not have vital importance, [baloban] can nest, also, under the conditions of anthropogenic landscape. In recent years in connection with an increase in the popularity in the world of falcon huntings are noted the cases of capture and removal of [balobanov] beyond the limits of edge and Russia. In the case of the growth of this tendency of [baloban] it can prove to be under the threat of disappearance ([Syroechkovskiy] and other, 2000). Shooting and capture of [balobana] as the form, introduced into the Red Book RF, is everywhere forbidden. Form is included in the appendix OF THE II convention [SITES] ([Syroechkovskiy] and other, 2000). |
Propagation. [Baloban] is extended from the southern boundaries of edge to the latitude of the cities Of [achinska], [Sushkiy] (Krasnoyarsk, of 1914; [Dementev], 1951; [Stepanyan], 1975). In the beginning [KHKH] v. it was noted near the sett. Of [balakhta], in Lake. [Salbat], in the environments g. it is Minusinsk, in the large lake (God), in eastern [Sayane] On the Border with the Krasnoyarsk wooded plain ([Sushkin], 1914), where it is regularly encountered at present. On the nesting place of [baloban] it is found under g. with Krasnoyarsk (Kim, 1988), on the valley r. Of [bazaikhi], on r. to the Yenisey in g. Of [divnogorska], also, in the region of Krasnoyarsk reservoir (Yudin, 1952; [Polushkin], 1988). It nested in 1976. on fan leisure within the boundaries g. of Krasnoyarsk, it was observed in s. [Dodonovo], also, on r. of guard (to the left tributary of the Yenisey). The nests of [balobana] are found in the environments of the villages Of [kogunek] and [Novomaryasovo], in The [krasnoturanskom] pine to boron, on The [batenevskom] mountain ridge (Kochanowski, 1991). 
Multiplication. [Baloban] of nests does not build, but it lays eggs into the old nests of predators, located on trees or ledges of cliffs. Frequently the nests are arranged at a high altitude, in the niches, closed on top, or deep slots, often without any bedding. [Balobany] begin to nest usually on the second year of life. Value of laying from 2 to 5 eggs. Greatly they will extend the period of multiplication. In the southern regions of edge the layings appear in the second-half of April, but separate pairs take up the multiplication considerably earlier. In the first half of June almost in all nests already there are nestlings. The periods of the departure of young are also extended - from the second-half of June to the middle of July. The latest encounter of [balobana] in the region g. of Krasnoyarsk is registered on November 24 (Yudin, 1952). The part of the birds remains to winter in the southern regions of edge (bushes, of 1982; Prokofiev, [Kustov], 1988).
Number. [Baloban] is relatively rare, but by places it can be usual. In 1970- X years its number in the forest-steppe part of the Minusinsk basin comprised: on the left bank r. of the Yenisey - 2-3 pairs to 100 [km]2 of territory, or of 5-7 pairs to 100 [km]2 of scaffolding; on the right bank of the Yenisey not more than 1 bird by 100 km of route, or of 0,5 pairs to 100 [km]2 of scaffolding (bushes, 1981; Bushes, 1982). In the environments g. of Krasnoyarsk at present the number composes 1-2 pairs on 100 km of route, in the pond Of the [kizira] rivers, the tubes ([Kuraginskogo] region) - 4-5 pairs, in Shushenskoe and Yermak regions - 3-4 pairs, in The [usinskaya] basin - 2-3 pairs, in The [sharypovskiy] region (environment Lake. Large) - 1-2 pairs on 100 km of route (Baranov, 1988). The number of [balobana] during [KHKH] of century in the region never was high, moreover, this only from Sokolov, whose livestock not only was not reduced, but by places even it grew (Baranov, 1991).[Back] |
