In this work we assess the data on the food of the Imperial Eagle (Aquila heliaca) in two separate nesting populations: one in Western Slovakia (21 pairs), the other in Eastern Slovakia (30 pairs). In Western Slovakia between 1978 and 2005 we recorded a total of 562 food items, consisting of 33 species of animal. The species predominantly featuring in the food were the brown hare Lepus europaeus (40.2%), common pheasant Phasianuscolchicus (17.3%), feral pigeon Columba livia domestica (11.7%) and the common hamster Cricetus cricetus (11.6%). In Eastern Slovakia between 1971 and 2005 we identified a total of 524 food items, made up of 30 animal species with slightly varying predominance of the same principal kinds of prey: L. europaeus (29.0%), C. cricetus (27.7%), P. colchicus (8.4%) and Columba sp. (8.2%). Imperial Eagles nesting in Slovakia are affected by the consequences of a marked reduction in population density of steppe-type rodents, especially ground squirrels (Spermophilus citellus) and hamsters (C. cricetus) and have become dependent for their food mainly on the prevalence of other small animals (L. europaeus, P. colchicus) and pigeons (C. livia domestica). Pairs nesting in neighbouring Hungary had similar prey, but a different order of predominance of the species (Haraszthy et al. 1996): C. cricetus (51.0%), L. europaeus (12.0%), P. colchicus (11.6%) and S. citellus (7.4%).
