Fig. 7. Frequency distribution (N=60) of the time between prey patches for four Magellanic penguins foraging from Punta Norte, Argentina. The inset shows all data for periods up to, and including, 6 h, to highlight the bimodality of the data, whereas the main graph shows only those data for up to and including 120 min, to show more detail. Note that these data do not include periods where birds presumably rested overnight.
