Survival and recovery rates of American eiders in eastern North America

We analyzed banding and recovery data of adult female American eiders (Somateria mollissima dresseri) captured during the breeding season in eastern North America. We estimated survival rates for birds originating in the Atlantic Coast subpopulation to be 0.8730 +- 0.0156 (SE) while recovery rates were 0.0101 +- 0.0080 (SE). Support for several banding reference areas of American eiders was found. No trends were detected in band recovery, harvest rates or harvest over time.
