White-tailed sea eagles (Haliaeetus albicilla) were almost extinct in the German federal state of Schleswig-Holstein in the 1980s, with only 4 breeding pairs being left. But due to intensive protection measurements the population has steadily grown up to 84 breeding pairs in 2015 (www.projektgruppeseeadlerschutz.de). Since the year 2000 nearly all of the free-living white-tailed sea eagles that are found sick or injured in or near Schleswig-Holstein are submitted to the rehabilitation centre of the Wildlife Park Eekholt. Altogether 47 eagles were examined and treated there between June 2000 and March 2016 in close cooperation with the
small animal clinic of the Freie Universität Berlin. In our presentation we give an overview of the causes of injury or disease in these birds. Most of the submitted eagles suffered from trauma (n = 22, 47 %), in many cases caused by wind turbines (n = 10). More than a quarter of the eagles (n = 13, 28 %) were intoxicated e.g. by lead (n = 6), organophosphates/ carbamates (n = 2) or zink (n = 1) or showed signs of intoxication (n = 4). Four eagles (8 %) showed permanent feather disorders like pinching off syndrome. In seven cases (15 %) the origin of disease remained unclear. One young eagle (2 %) was submitted malnourished due to disturbances at the breeding place. Eagles that had to be euthanised because of a poor prognosis or that died during rehabilitation usually underwent a post mortem examination at the IZW. At least half of the white-tailed sea eagles that were submitted to the rehabilitation centre of the Wildlife Park Eekholt in the last 16 years were injured or damaged as a result of anthropogenic environmental changes.
