Also, owls have asymmetrically placed ears and ear openings (, and their hearing is tuned finely enough that the difference in timing and intensity of when the sound is heard by each ear helps them locate distance and direction of the sound . Tyto owls use their facial disc as a parabolic disc for sound catching and channeling it to the ears, and by moving it they can help accentuate the sound and when it reaches each ear, thus helping them locate the source of sounds. (There is an excellent description of all this on pages 13/14 of Stephen Debus' The Owls of Australia.)
