Fig. 6. Relationships between (A) bottom-phase duration and mean ascent body angle within a dive and (B) bottom-phase duration of a dive and mean descent body angle of a subsequent dive in a macaroni penguin (MK1). Colours of plots represent ranges of bottom-phase start or end depth (black for <20 m, green for 20–40 m, red for 40–60 m, blue for >60 m). Regression lines are for each depth range.
