Aerodynamic theory predicts that the power required for an animal to fly over a range of speeds is represented by a ‘U’-shaped curve, with the greatest power required at the slowest and fastest speeds, and minimum power at an intermediate speed. Tests of these predictions, based on oxygen consumption measurements of metabolic power in birds and insects, support a different interpretation, generating either flat or ‘J’-shaped power profiles, implying little additional demand between hovering and… CONTINUE READING
