Candling and Field Atlas of Early Egg Development in Common Eiders Somateria Mollissima in the Central Baltic
Here we present the results of candling 258 eggs from 50 nests of Common Eiders Somateria mollissima in a colony in the central Baltic. Of these, 223 (86%) had a developing foetus. Among the 35 (14%) failed eggs, 15 were unfertilized and 20 contained a dead embryo. The prevalence of failed eggs is s...
