Bird biomechanics 2

Swift wings, compared with those of typical birds, have proportionately large wingtip bones (green), giving added maneuverability in flight. By changing the angle between the wingtip bones and the forelimb bones (blue), swifts alter the shape and area of their wings, thereby maximizing their efficiency at various speeds.
