Prey selection by Toads (Bufo bufo L.) in response to configurational stimuli moved in the visual field z,y-coordinates

  • A. Beck
  • J. -P. Ewert


Recognition of prey-like stimuli by the Common Toad depends on both the shape of the stimulus and its direction of motion. To evoke preycapture the direction of motion must be parallel to the long axis of the stimulus. We show here that the same relation between shape and direction of motion applies to stimuli which moved towards or away from the toad, and that retreating stimuli are more powerful releasers than approaching ones.
