Winter distribution of Steller's Eiders in the Varangerfjord, northern Norway

Abstract: Arctic warming and decreasing sea-ice cover along the Siberian coast in the Arctic Ocean leads to greater accessibility for operations such as oil drilling and traffic of tankers. This implies increasing risks for Steller’s Eider Polysticta stelleri wintering, moulting and staging along the coasts of the Varanger Peninsula, Norway. Steller’s Eiders were surveyed by monthly counts during winter and early spring 2016/2017 to investigate numbers and distribution throughout the winter. The highest number of winter… Show more

“…However, the closely related Bald eagle ( Haliaeetus leucocephalus ), is known to aggregate and feed at Pacific salmon spawning sites in North America (Levi et al., 2015 ; Restani et al., 2000 ). Furthermore, the white‐tailed eagle is known to be an efficient scavenger and predator in aquatic environments (Witman et al., 2014 ), and has previously been suggested to be a scavenger of pink salmon (Dunlop et al., 2021 ), is abundant in Norway (Folkestad & Probst, 2013 ; Heggøy & Øien, 2014 ), and is highly mobile (Duvall, 2022 ) which allow aggregative responses to abundant food sources (Gutiérrez‐Cánovas et al., 2020 ).…”
