Energy Constraints on Incubating Common Eiders in the Canadian Arctic (East Bay, Southampton Island, Nunavut)
Common eider ducks have a circumpolar distribution. Several populations that occur in polar areas during the summer move to northern or temperate coastal areas during winter. All eider species have delayed reproductive maturity, low rates of recruitment, and high rates of adult survival (often 15 +...
