The White-tailed Sea Eagle Haliaeetus albicilla and the Common Eider Somateria mollissima in the Gulf of Kandalaksha, White Sea
// Status of Raptor Populations in Eastern Fennoscandia. Proceedings of the Workshop, Kostomuksha, Karelia, Russia, November 8-10, 2005. Petrozavodsk: KarRC RAS, 2006. Pp. 49-55
Keywords: White-tailed Sea Eagle, diet, predation, Common Eider, reproduction, Gulf of Kandalaksha, White Sea, Haliaeetus albicilla, Somateria mollissima.
In the past several decades, mortality of Common Eider clutches and incubating females due to predation has increased notably in the Kandalaksha strict nature reserve sites in the Gulf of Kandalaksha. At present, predation by the White-tailed Sea Eagle is the main factor undermining Eider reproduction success in reserved areas. The impact of other raptors, corvids, and predatory mammals is less significant, although it has also grown lately.
