Wesley the Owl - Facts or Fiction?

["Tom and Mandy Wilson" <>]

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.)
