Costs and consequences of male attendance behaviour at common eider colonies
Typically male ducks follow females to breeding grounds, where males mate guard through nest searching and egg-laying, but do not follow females to nests. However, male Common Eiders ('Somateria mollissima') attend females at nests during early stages of nesting. The questions that arise a...

Typically male ducks follow females to breeding grounds, where males mate guard through nest searching and egg-laying, but do not follow females to nests. However, male Common Eiders ('Somateria mollissima') attend females at nests during early stages of nesting.

I tested whether male Common Eiders balance predation risk against possible reproductive benefits of attending females.
