Fig. 6. Frequency distribution of the number of consecutive dives (black bars; N=302) where Magellanic penguins (N=25) foraging from Punta Norte, Argentina, were considered to be exploiting a prey patch (this being defined by higher swim speeds; see text) and the frequency distribution of the amounts of estimated food ingested per patch for Magellanic penguins (grey bars; N=4 birds for 65 patches) foraging from Punta Norte, Argentina. Note that these two data sets were not derived from the same birds (see text).
