Abstract:

The study was conducted in the years 1989-1993. The Black Kite fed primarily on birds and fish. Red Kite - on birds, mammals and carrion, the White-tailed Eagle - almost exclusively on birds and fish, and the Lesser Spotted Eagle on small mammals, birds and frogs. The White-tailed Eagle was the most specialised species. Its food niche breadth was smallest among the studied species and food taken in water habitats accounted for 95% of its diet. The Black Kite had the widest food spectrum in terms of the frequency of prey while the Red Kite - in terms of the biomass consumed. The mean body mass of prey specimens taken by the White-tailed Eagle was 578 g, by the Red Kite - 235 g, the Black Kite - 230 g, and the Lesser Spotted Eagle - 34 g. The food niches of both Kites and the White-tailed Eagle strongly overlapped. The smallest overlap was between the food niches of the two Eagles and between the Lesser Spotted Eagle and the Black Kite.
