Figure 2

Energy-budget model validation plots. (a) Total TNEG converted to mass units (predicted body mass change) should approximate to body mass change between the arrival and departure (observed). 5 complete foraging trips were only available out of 18. Red and black dots represent predicted body mass change based on fine-scale (FS; 10 activities) and wide-scale (WS; only flying and resting) activities, respectively. (b) Histogram of the observed distribution of body mass change for incubation and brooding. Predicted values are represented by red dots. (c) Individual predictions of energy expenditure (mean and interval confidences) based on heart rate (HR) values corresponding to 18 albatrosses contrasted against an empirical distribution of energy expenditure based on the Doubly Labelled Water (DLW) method (grey histogram) from [44–46]. Individual predictions differed by considering wide-scale (WB in black, only flying and resting) and fine-scale (FB in red,10 activities from A to J, Figure  1) activities.
