Abstract

Several studies on wind turbine collision mortality in raptors suggest a bias towards adult birds, while sex-biased mortality has not yet been documented. We compared collision mortality in relation to all known causes of mortality and in relation to demographic data for the German population of the White-tailed Eagle and found collision mortality to be sex biased but not age biased. We suggest that these contrasting results may in part be explained by the lack of baseline data about the demographic structure of surveyed populations in previous studies. Our results stress the importance of baseline data for inferring demographic consequences of wind turbine collision mortality.
