King Eider at Yellowknife – December 1983

Timing and Distance of King Eider Migration and Winter Movements

Understanding the patterns, extent, and phenology of migration is important for estimating potential influences of habitat or climate changes on populations of migratory birds. We used satellite telemetry of 100 individual King Eiders (Somateria spectabilis) tagged in northwestern North America in 2002–2006 to describe the timing and extent of their migration and winter movements in the Bering ...

Long-term surveys on Traill Island (Northeast Greenland) show that numbers of king eider (Somateria spectabilis) nests are correlated with high densities of collared lemming (Dicrostonyx groenlandicus). These observations match other zoological records from this region and agree with similar observations recorded elsewhere for arctic geese. Processes at work may be related to the fact that mamm...
