Factors affecting plasma concentrations of prolactin in the common eider Somateria mollissima
In the common eider only the females incubate while they fast for 25 days. Thus, since they rely entirely on their body reserves for successful incubation, they can be defined as capital incubators. To assess the po-tential effects of their initial body mass, the incuba-tion duration, and depletion...
