Energy expenditure and food consumption of foraging Imperial cormorants in Patagonia, Argentina
Energy management during the breeding season is crucial for central place foragers since parents need to feed themselves and their offspring while being spatially and temporally constrained. In this work, we used overall dynamic body acceleration as a measure of activity and also to allude to the fo...
