There was a mismatch between the units reported for the base metabolic rate, c0, in figure 3c in [1] and the corresponding units in the main text and labels of figure 3a,b. Instead of the rate c0 being shown in 1 per hour, the label of the x-axis in figure 1c was given in 1 per second. The corrected figure is shown below. None of the findings of the paper have altered.

(a,b) Relative energy payoff difference Δf versus hunter group size N for different attack delay times Tfr with c0 = 0.0001 s−1 = 0.36 h−1 and different values of the relative energetic costs of attacks δc = 100 (a) and δc = 500 (b). (c) Relative energy payoff difference Δf versus c0 and δc for fixed Tfr = 0.5 h and N = 10 (blue region indicates Δf < 0; i.e. where free riding is not beneficial). All other simulation parameters as in the main text and electronic supplementary material, S2.4 of [1].
