Figure 5


Fig. 5. The predicted net energy gain (R, in W) calculated with observed ground speed (Vg), air speed (Va) and flight strategy combinations. Different symbols (+ flapping, {circ} soaring) represent the predicted R for a measured combination of Vg, Va and flight strategy for black-headed gulls (A) and lesser black-backed gulls (B). Parameter estimates for R calculations are as follows: En=20 W, D=10000 m, tp=1800 s. As observed Va and Vg values are highly confounded (see Fig. 4), R was not plotted against both Va and Vg.
