Fig. 3From: Time and energy costs of different foraging choices in an avian generalist speciesTime and energy costs averaged per individual over a chick rearing period, plotted against the individual’s proportion of marine foraging trips. a average number of foraging trips per day, b average trip duration, c average of the total daily sums of ODBA and d average time spent outside of the colony in a day. Regression lines are plotted for the significant relationshipsBack to article page
