The distribution of model residuals for benthic diving, against dive depth and time. The frequency distribution of residuals from the final model with hFI = –HS plotted against dive depth (a) and month (b) showed a positively biased peak at 50 m depth around January. This also corresponds to an increased frequency of diving around 50 m during that period (c). Residuals for benthic diving with hFI = MT and –1000/RT showed very similar patterns and are not presented in the figure
