Common eider (Somateria mollissima v-nigrum) nest cover and depredation on Central Alaskan Beaufort Sea barrier islands / Lynn E. Noel, Stephen R. Johnson, Gillian M. O'Doherty, Matthew K. Butcher.

Title: Common eider (Somateria mollissima v-nigrum) nest cover and depredation on Central Alaskan Beaufort Sea barrier islands / Lynn E. Noel, Stephen R. Johnson, Gillian M. O'Doherty, Matthew K. Butcher.

Date: 2005.
In: Arctic. (2005.), Vol. 58(2) (2005)
Abstract: Previous studies of female common eiders (Somateria mollissima v-nigrum) show positive relationship between nest success and driftwood cover. Five years of nesting data were used to evaluate whether cover enhances nest success when mammalian predators are present. Nests were surrounded by low or moderate driftwood cover. Nest failure rates were high (32%-95%), and arctic foxes (Alopex lagopus), alone or with polar bears (Ursus maritimus), appeared to be more destructive than glaucous gulls (Larus hyperboreus). When foxes were present, nest activity consistently decreased with increasing cover. Models support observations that nest cover was beneficial to eiders when glaucous gulls alone were predators. Driftwood cover may be most important for thermal and structural protection, rather than camouflage.
