Field signs. Melky Sokolok. Male all black with ryzhimi "shtanami and podhvostem. Łapy red. A female gray top, bottom ohristy head red. Zametny "mustache". Few careful, especially in the slot. Voice - calls "ki-ki-ki" (Syroechkovsky, Rogacheva, 1980). Distribution. Kobchik - dweller steppe, forest and cultural landscape. To the north distributed to the city The Yenisei (Bursky, Vakhrushev, 1983), found a village Vorogovo, KOICA and Peace (Rogacheva, 1988). At nesting recorded in the upper river. Podkamenaya Tunguska, at the mouth of r.Chamby (Syroechkovsky, 1959), on the river. Angara and r.Chadobtse (Reymers, 1966). In the southern taiga and especially in podtayge north of Krasnoyarsk was typical of open landscapes (Tugarinov, Buturlin, 1911; Sushkin, 1914; Yudin, 1952; Cousteau, 1982). At the southern edge of Achinskoy found in the forest, Minusinsk and Usinskoy basins (Syroechkovsky et al, 2000).
Habitats. Sokol southern open spaces, kid-continuous forests. Favorite Places nesting in the steppe and forest - River uremia. In the taiga sometimes penetrate open river valleys and on the edges of forests. Specificity in choosing the type of habitat is the preference for them to sites of high forest and open landscape. In these areas may soon settle on a few pairs (Syroechkovsky et al, 2000). Reproduction. For the construction of other uses nesting birds - kite, crows, forty, rooks, sometimes nest in hollows on the bushes (Karagan, willow), occasionally - in burrows and on the ground among bushes. In laying eggs, usually 3-4, nasizhivayut both parents. Flight chicks from nests there at the end of June (Tugarinov, Buturlin, 1911). Vyvodki stick to the nest for about two weeks (Syroechkovsky et al, 2000). Nutrition. The main food - insects, which kobchik lapami catches on the fly and gather from the earth (Syroechkovsky et al, 2000).
Number. In the early twentieth century and until 1950 in the southern edge of kobchik was quite numerous (Sushkin, 1914; Yanushevich, Yurlov, 1950), but in the late 1970's, his numbers rather dramatically decreased (Cousteau, 1982). Nevertheless, at some sites Minusinsk depression its nesting numbers reached 0.08 individuals per km 2 (Cousteau, 1982). Limiting factors. It seems that the disappearance of kobchika linked to the processing fields with pesticides, which are known to accumulate in the body of insects - mostly stern of the falcon. One of the major constraints is the lack of optimum conditions for nesting - of high trees and good forage base near nesting (Syroechkovsky et al, 2000). References. |
