On eastern imperial eagle (Aquila heliaca) breeding in atypical habitat under competitive conditions with other eagle species
Abstract In the paper we describe two cases of eastern imperial eagle breeding in the former nests of greater spotted eagle and white-tailed eagle observed in the Tatarstan Republic, Russia. In both cases, eastern imperial eagles occupied non-favourable habitats they never used before - a vast alder forest in the wetlands and an island in a reservoir. The possible reasons that made the eagles expand their breeding ranges in the Volga region ofRussia are discussed in this paper Abstrakt V príspevku popisujeme dva prípady hniezdenia orla královského v hniezdach po orlovi hrubozobom a orliakovi morskom, pozorované v Tatárskej republike v Ruskej federácii. Orol královský obsadil, v oboch prípadoch, suboptimálne habitaty, ktoré doteraz takto nevyužíval - rozsiahle slatinné jelšiny a ostrov na vodnej nádrži. V práci rozoberáme možné príciny stojace za rozširovaním hniezdneho areálu druhu v ruskom Povolží.
