Description
Summary:During the long-term research on White-tailed Eagles (Haliaeetus albicilla) conducted in the continental part of Lithuania since 1995, live Common Buzzard's (Buteo buteo) nestlings were found in nests of two pairs of eagles in 2002. On the one hand, this could have been atypical feeding behaviour of eagles: adult birds used to bring buzzard's nestlings to their nests, keep them alive there and feed them up to their own nestlings later. On the other hand, this could have been breeding parasitism of Common Buzzard on White-tailed Eagle.
