Migratory Birds: Population Trends of King and Common Eiders

Establishing population counts of King and Common Eiders on the North Slope.

The eiders that migrate through northwest Alaska nest at dispersed locations across northern Alaska and Canada. Because they are widespread it is difficult to get a good population estimate. Most of the population, however, migrates near Barrow during the spring and then again in the summer/fall. We counted eiders and other birds as they migrated past Barrow.

King (Somateria spectabilis) and Common (Somateria mollissima) eiders are important subsistence species in Alaska, Canada and Russia, yet relatively little was known about their population size, trends, movements or breeding biology. The NSB initiated studies in the 1990's to help fill these data gaps.

Aerial surveys showed that the King Eider population had declined, but very little was known about its breeding biology or specific migration routes or habitat use at sea. Several studies were initiated to learn more about the breeding biology, including reproductive success and habitat selection and use, of King Eiders. Comparisons were made in timing of nesting, nest success, and habitat use between an undeveloped site near Teshekpuk Lake and a developed site near Kuparuk oilfield.
