Record #110945:

Breeding population size of the Common Eider Somateria mollissima in Kongsfjorden, Svalbard, 1981-1987 / Fridtjof Mehlum.

Title: Breeding population size of the Common Eider Somateria mollissima in Kongsfjorden, Svalbard, 1981-1987 / Fridtjof Mehlum.
Author(s): Mehlum, Fridtjof.
Date: 1991.
In: Norsk Polarinstitutt. Skrifter. (1991.), Vol. 195 (1991)
Abstract: Total number of breeding pairs fluctuated between 1,000 and 3,400, depending on sea-ice conditions in fjord. In seasons with late break-up (1981 and 1986), fewer eiders occupied their breeding islands. Proportion of breeding pairs on each island also varied: in years with early ice break-up and snow-melt, majority of eiders nested at relatively low density on largest island; in years with late break-up and snow-melt, most of breeding birds inhabited smaller and outermost islands. Egg-clutch sizes varied with laying dates, with smallest clutches late in season.
