- we know that the Imperial Eagle does not inhabit here at the moment, or only single pairs

- we know that the Imperial Eagle inhabits here, but the territory is not surveyed in detail

- we know that the Imperial Eagle inhabits only according to literature data; it was not surveyed by us


At present 1,686 Imperial Eagles nesting sites are known in Russia - 49% of estimate of it population at 2.5 million sq km area in the country

580 nesting sites are known in Kazakhstan – 16.5% of estimate of it population at 2.5 million sq km area in the country

Total number:

3 489 (3 181 – 3 797) in Russia 3 605 (3 220 – 3 990) in Kazakhstan










31 245 sq. km A key area in Volga region with two study plots


1990’s


222 potential br. ter.


2010

119 b.tr. were checked



2013






18 study plots 5,000 sq. km


1600 sq. km

375 br. ter. on 800 sq. km



1908 active nests are in database of RRRCN 300-500 breeding territories annually monitored In 2008-2013 70% of all sites were examined for monitoring



What are results of monitoring?




New breeding group of Imperial Eagle at forest lines in the north of Western Kazakhstan

With increasing number of the species in the steppe zone, he settles deciduous trees and the proportion of pairs nesting on coniferous trees, naturally, falls

•• ••

хвойные (сосна) Coniferous (pine) – – 49% 49% лиственные – 51% Deciduous – 51%

• Coniferous (pine) – 35% • Deciduous – 65%


Similar processes occur in Russia, where most of breeding pairs nest on the suit conifers


• Coniferous – 78% • Deciduous – 22%

• Coniferous – 70% • Deciduous – 30%


In Russia and Kazakhstan Imperial Eagle rapidly occupy power lines

• PL – 3,5% (n = 1182)

• PL – 5% (n = 1908)


The process of colonization of transmission lines by eagles in Kazakhstan is moving to west through the steppe zone and has already reached Volga and Don basins, and some pairs began to settle power lines in the forest-steppe zone


For 5 years productivity of the Imperial Eagle in Volga-Ural sands significantly reduced, due to the drop in the number of Sousliks


but grew up in the steppes of Kazakhstan and in Altai-Sayan region


Color ringing program of Imperial Eagle in Russia and Kazakhstan started in 2012

55 Imperial eagles were ringed in 2012 and 97 in 20



In addition to colored rings aluminum rings with double black code is also used for ringing eagles in Kazakhstan


Eagle from Tatarstan was met in Iraq, as we were informed thanks to the ring and web-site


The entire database by ringing eagles available on-line on the website of the Russian Raptors Research and Conservation Network
