Initial findings were reported as: Barn Owls use ITD's as Elevation Cues, Animal Behavior Society (NERABS) Meeting, Univ. of New Hampshire, Northampton, MA 1994.
Barn owls have asymmetrical ears and can locate the sound of prey horizontally and vertically in total darkness. Current research since the 1970's believes that horizontal location cues came from time and vertical from intensity differences as sensed by the owl's ears. In 1994 I challenged the view that intensity differences played any part in sound location and reported statistical evidence that points to time differences as the cues to both horizontal and vertical locations. Article submission for publication in a peer review journal was not accepted. Continue reading "Sound Location in the Barn Owl" »
