Abstract

While most nest-dwelling birds depend on parental brooding to maintain normal body temperature(TB) during the first days of life (Riclefs, 1974), nest-fleers appear to rely on endogenous heat (Koskimies and Lahti,1964). We have studied eider ducklings breeding near the Research Station of The Norwegian Polar Institute at Ny Ålesund, Svalbard (79° 55′). The young eiders leave the nest once they have dried at the age of 6–8 hours and from then on spend most of their time on the ice-strewn water.
