Abstract

The barn owl (Tyto alba) can localize noises containing frequencies (5~8 kHz) accurately in both azimuth and elevation. The accuracy of localization decreases as a function of the target position relative to the midline of the face. Theowl uses both ears to determine the target position without head movement. The cues for localization are binaural intensity difference for elevation and "on-going" time difference for azimuth. The use of binaural intensity difference for elevation is due to the asymmetrical positions of the ear openings.
