Abstract The Golden Eagle Aquila chrysaetos established a breeding population in Denmark in 1998. Since then, at least 53 individu-
als have fledged yet the breeding population has remained small at 3-5 pairs. In this study, we used GPS/GSM-tracking technology
to investigate dispersal and present individual spatiotemporal histories during the first year of life of Danish Golden Eagles, with
notes on survival and causes of mortality. In total, nine individuals were tagged with GPS/GSM-transmitters during a seven-year
period (2015-2021). Our results show that six individuals managed to disperse (> 5 km from nesting site), while three individuals died
before dispersal. Status at the end of the study for the tagged individuals was: three were alive, the fate of two was unknown, and
four were dead. We found a median fledging date of 3 July (ranging 15 June to 28 July) and a median dispersal date of 2 December
(ranging 14 October to 21 April the following year). Mean dispersal distance for all dispersed individuals from nest site was 99 km
(range 0.7-272 km) at the age of six months. By the age of one year, mean distance from nest site was 68 km (range 5-166 km). Our
study confirms high mortality during the first year as shown in a number of other studies and provides further evidence that first
year dispersal period is critical for juvenile Golden Eagles. This study contributes important knowledge for future conservation and
management of Golden Eagles breeding in Denmark.
