sentences:  The largest study of the eastern imperial eagle’s dietary habits known occurred in the vast Naurzum Nature Reserve in Kazakhstan, where 11,079 prey items were reviewed.The prey spectrum was exceptionally diverse here, with no one prey reliably being favored by the imperial eagle pairs, despite an ample colony of yellow ground squirrel ("Spermophilus fulvus") and russet ground squirrel ("Spermophilus major") being nearby and at least three other species of eagles with nearby nesting sites presenting possible resource competition.Without presenting the metrics, apparently birds were the highest volume prey for the imperial eagles, especially corvids, namely the rook ("Corvus frugilegus") and Eurasian magpie ("Pica pica"), numerous species of duck as well as Eurasian kestrels ("Falco tinnunculus") and little bustards ("Tetrax tetrax").
