Recent changes in the status of Steller's Eider Polysticta stelleri wintering in Europe: a decline or redistribution?
Steller's Eider Polysticta stelleri has a restricted arctic breeding range. The world population declined to c . 220,000 individuals in the late 1990s from an estimated 400,000–500,000 in the 1960s. The species has a limited global wintering distribution, occurring in marine habitats in north-e...
