Concerning European waterbirds, for instance the north European populations of mallard Anas platyrhynchos have been declining or stable, the Baltic breeding population of the common eider Somateria mollissima has decreased, the Baltic and Scandinavian populations of the common merganser Mergus merganser have probably decreased, and the populations of the goldeneye Bucephala clangula in northern and northwestern Europe have been stable (Wetlands International 2006).
Common eiders Somateria mollissima typically have high nest success in the absence of disturbance (Bolduc & Guillemette 2003) but low duckling survival (10-25%), mainly because of gull predation in the first weeks after hatching (Ahlund & Gotmark 1989, Mawhinney & Diamond 1999, Donehower & Bird 2008).
