  1. R 2 of Spearman correlations between hunting timehighres and hunting timelowres. Huntinghighres time is the total time spent in “huntinghighres” mode (highly sinuous phases of the dive) per high-resolution dive (see “Fine scale analysis of foraging behaviour”, [21]). Hunting timelowres is the sum of the total time spent per low-resolution dive in segments associated with vertical velocity inferior to a defined threshold. The set of thresholds tested was chosen to encompass the first mode of the distribution of the vertical velocity associated with each segment in low-resolution dives (see Fig. 2)
