Influence of prey densities in the distribution and breeding success of Bonelli's eagle (Hieraaetus fasciatus): management implications

摘要: Diet, prey availability, and breeding success were studied in a population of Bonelli's eagle (Hieraaetus fasciatus) the province Granada, SE Spain. The densities main species, European wild rabbit (Oryctolagus cuniculus), red-legged partridge (Alectoris rufa), wood pigeon (Columba palumbus), rock dove livia), representing 90.2% biomass, analysed 19 territories occupied by pairs eagles 15 potential that unoccupied but appropriate for nesting. We found no significant differences density between two types territories. Contrary to other raptor we relationship their species distance neighbouring pairs, either success. These findings, together with prior knowledge nest-site selection this study area, can be used proper planning conservation strategies. should avoid unnecessary effort increase eagle's food supply, promote reintroduction individuals suitable sites eagle.
