Natal dispersal is a crucial period for raptors with serious implications individuals’ survival and population demography. In this study we analyzed data from 18 GPS-tracked golden eagles in order to describe their ecology northern Greece, where the species feeds mostly on tortoises. Young our dispersed at 176 days post fledging, spent first year of independence relatively close (40–60 kms) natal ranges exhibited variable temporary settlement behavior. Overall range sizes did not differ seasonally, but area were significantly larger winter. Three survived territorial occupied 20–60 kms areas. The application refinement Scottish GET ranging model suggested that used areas had higher topographical relief lower canopy cover during dispersal. Habitat heterogeneity seems also be influential settlement. Our provide both such insights southern eastern Europe method delineating species. findings can explained terms food habitat availability. We highlight importance conserving heterogeneous open complex topography applying proactive management measures within population’s conservation.
