: The Cormorants were shot as lethal control measure (permit 67.1-2.03.20-pi, 09-2014, Untere Naturschutzbehörde Rhein-Sieg-Kreis) during winter 2015/2016. The Duck was obtained from a commercial breeder. No approval is required because feathers and glands were taken from dead animals or collected at molting places.
