The flight paths of two blue bottle flies (Calliphora vomitoria) sampled from high-speed video (S1 Movie): A) at the rate of the visual system of a human (40 frames/s) and B) at the rate of a pied flycatcher (120 frames/s) at a light intensity of approximately 500 cdm-2. The flycatcher refreshes visual input almost three times faster, resulting in a much more detailed view of the flight paths of the flies.
