SUMMARY
Animals should minimize the energetic costs of movement during foraging while maximizing caloric intake to maximize net energetic gain. This striking motility is underpinned by an exceptionally efficient flight strategy known as "dynamic soaring", whereby seabirds exploit the wind velocity gradients ("wind-shear") close to the surface of the ocean, ascending into the wind and descending with the wind, thus gleaning aerodynamic kinetic energy. While wind-shear soaring provides most (~80-90%) of the total energy for sustained soaring, additional energy can be extracted by seabirds by exploiting wave-induced features of the wind . . .
