Abstract: | The level of fidelity to potential nest site in representatives of different bird of prey species (Falconiformes) has been studied as dependent on population density and land-use status of the nesting area (a specially protected natural area or unprotected forest area). Species with high and low parameters of nest site fidelity and occupancy have been distinguished. The former group includes the Common Buzzard (Buteo buteo), Booted Eagle (Hieraaetus pennatus), and White-tailed Sea Eagle (Haliaeetus albicilla): no less than 60% of observed pairs have not changed their nest sites and nests during 5 years. The latter group includes the Common Kestrel (Falco tinnunculus), European Honey Buzzard (Pernis apivorus), and, at the nest level, Northern Goshawk (Accipiter gentiles). |
