Across landscapes and seascapes : The movement ecology of diving and flying guillemots and gulls during breeding
Some seabirds we encounter only fleetingly, as they fly by as we walk along the beach, or perhaps meet far out at sea when we take a boat trip. Others though we are more familiar with, such as the ‘seagulls’ that many will not even turn their head to appreciate. Yet, all seabirds have remarkable stories to tell, and we are fortunate now to live at a time where we can follow individual birds as theMost seabirds breed colonially, at which time they make central-place foraging trips. Parents must collect food both for themselves and for egg production/chick-rearing. How should they forage? I followed five species across two sites in Sweden in the Baltic Sea using GPS and time-depth recorder (TDR) devices, giving information on both flight and diving activity.
