Megjegyzések:	In this study we estimated the annual turnover rates, and so indirectly the possible maximum mortality rates of female Eastern Imperial Eagles (Aquila heliaca) in an expanding population. DNA was extracted from shed feathers collected in territories where at least three consecutive years of breeding occurred. As DNA samples could not be obtained at every studied nest in each year, minimum and maximum turnover rates were estimated. The calculated rates, 27.7% (minimum) and 35.5% (maximum), are much higher than what could be expected based on studies of other raptor species. According to previous studies territory switching can occur frequently in an expanding population. However, we found evidence of it in only two of the 46 studied territories, thus we assume that despite the ongoing saturation some level of site fidelity is present in the population. Our findings suggest the high prevalence of mortality, most likely from poisoning and electrocution, but also predict a large number of floater individuals that fill up the vacant territories.
