Capsule For breeding, areas dominated by extensive agricultural and rugged Mediterranean landscapesare preferred; maintenance of habitat heterogeneity and extensive agriculture are key for the conservationof this eagle.Aims To model breeding habitat preferences of Bonelli’s Eagles Aquila fasciata in Sicily, where the lastviable population still remains in Italy, in order to identify the most important habitats for conservation.Methods Pairs were monitored between 1990 and 2010. A case-control design throughGLMs was used attwo spatial scales: landscape and home-range. Variables included topographic, climatic, land-use, roadand descriptors of habitat heterogeneity. Information-based criteria were used to select the best subset ofpredictors.Results A total of 22 breeding pairs are still breeding, which represent about the 90% of the Italian population.The best models at both scales showed that Bonelli’s Eagles were clearly associated with Mediterraneanfeatures, including rugged areas surrounded by extensive arable land, shrubland and herbaceousvegetation. Our results emphasize the negative effects of habitat fragmentation and agricultural intensificationon the probability of occurrence of Bonelli’s Eagles.Conclusion The distribution of Bonelli’s Eagles in Sicily can be described by a relatively small number oftopographical and land-use variables. The maintenance of habitat heterogeneity is key for the conservationof this endangered raptor.
