Re: pteros have lift-off

On average, with increasing body size, span, and speed - relative flapping amplitude decreases. Pigeons use a very wide flapping arc during steep, burst launches because of the launch angle and speed regime (they are in an anaerobically powered, steep-climbing vortex ring gait, and this requires a relatively large flapping amplitude).
