The article provides the results of the 2017-2018 inspection of 14 long-term nesting sites of Spotted Eagle Aquila clanga, Imperial Eagle A. heliaca, White-tailed Eagle Haliaeetus albicilla, and Eagle-owl Bubo bubo in the Kurgan region. The sites were discovered in 2000-2014 and inspected again in May, 2017 and May, 2018. In 2017, only 8 nesting sites (57%) were inhabited. In 2018, 2 more sites no longer existed (both had been inhabited by Eagle Owls for at least 5 years). The most persistent are Imperial Eagle nesting sites (inhabited for at least 18 years) and those of White-tailed Eagle (used for at least 10 years). Birds of the same species often occupy the same nest every year. However, some pairs changed the location of the nest shifting it for up to 100 m (Spotted and Imperial Eagles) or up to 200 m (White-tailed Eagle). : The article provides the results of the 2017-2018 inspection of 14 long-term nesting sites of Spotted Eagle Aquila clanga, Imperial Eagle A. heliaca, White-tailed Eagle Haliaeetus albicilla, and Eagle-owl Bubo bubo in the Kurgan region.
