Field signs. Large eagle, barely distinguishable at a distance from eagle-burial, but slightly smaller and lighter color. At the head is usually bright fox «cap». In less cautious than other eagles. Often sitting on telegraph poles, mound and other elevations. Hunts are usually on the ground - looking for prey on foot or sitting in one place, catches a short take-off at impended animal. Quite molchaliv. The voice is similar to small dogs yap ( «tyaf-tyaf-tyaf»), blind or croak kryahtene (Syroechkovsky, Rogacheva, 1995).  Distribution. In the Krasnoyarsk territory extended over a large subspecies steppe eagle (Aquila rapax nepalensis), mostly living in Central Asia (Syroechkovsky, Rogacheva, 1995). In the first half of the twentieth century. Separate meetings were qualified zalety isolated individuals. Over the past 50-70 years steppe eagle habitat has expanded to the north (Baranov, 1991). That eagle was a mark of Krasnoyarsk (Yudin, 1952), in Minusinsk Basin (Yanushevich, Yurlov, 1950; Cousteau, 1982) and Sayano-Shushenskoye Reserve (Sokolov et al, 1983; Petrov, Rudkovsky, 1985). He was found in an area near the Novoselovskom. Svetlolobovo (Kim, 1988) and nesting - in Khakassia (Prokofiev, 1987; Kohanovsky, 1991). Comparatively typical steppe eagle and the adjacent territories: the southern slopes of the West Sayan, in the Central Tuvinian and Ubsu-Nurskoy basins (Zabelin, 1976; Baranov, 1991; Syroechkovsky et al, 2000).
Habitats. Subtype steppe eagle, dwelling in the province, clearly avoids the plain areas, preferring steppe area with vsholmlennoy surface, the yields of small stones and rock formations (Syroechkovsky et al, 2000). Reproduction. Jacks are usually happy to rocky slopes of shallow among the stones, on hilltops, on separate ostantsah a flattened pyramid in the mountain steppes, less yielding on pripoymennyh rocky outcrops, sometimes completely flat surface (Syroechkovsky, Rogacheva, 1995) and, as an exception , On trees (Kohanovsky, 1991). Masonry steppe eagle is a 1-3 white eggs, but most of the two. Running time nasizhivaniya about 45 days. The young appear uneven. Cluster period lasts about 55 days. Flight chicks appear at the end of August (Syroechkovsky et al, 2000).  Nutrition. Basis nutrition steppe eagles - small mammals (ground squirrel, gerbil, zaytseobraznye), less often - the birds often feed on carrion (Syroechkovsky et al, 2000). Number. Rare type of Krasnoyarsk region: perhaps it is because the steppe eagle is at the borders of ecological optimum setting conditions for the existence of species. Therefore, its nesting in the Krasnoyarsk Territory is sporadic, and change the size depends largely on the status of populations in the middle range, namely on the territory of Tuva, and Mongolia (Syroechkovsky et al, 2000). Limiting factors. Due to the fact that the steppe eagle nest in relatively accessible locations, the nests are often razoryayutsya people, grazing cattle, dogs and predatory mammals (Baranov, 1991).
