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).
