Osteology of the eider, Somateria mollissima (L.): a study of sexual, geographic, and temporal morphometric variation in the eider skeleton. The female common eider plucks down from her own body to line a nest, in which she lays four to five eggs, on average (range 2 to 8).
After the second or third egg is laid, the female begins incubation. Incubation lasts for about 25 days and is only done by the female. About 50 percent of common eider eggs hatch g: Osteology.
