To Have Ultra Rapid Vision (VIDEO) Uppsala University This video is under embargo. Please login to access this video. Caption The video clip visualizes one advantage of the ultra rapid vision discovered in birds. The almost three times faster refreshment rate of visual input in a pied flycatcher than in a human makes it far easier to track and predict the flight paths of two blue bottle flies. This is most likely a crucial ability for a bird that catches its airborne prey on the wing.
