One adaptation animals have for hearing - very large ears (external pinnae). E.g: red fox, wolves Owls do not have large external pinnae/ears but instead have - hidden ears and hearing is one of their most developed senses. E.g: long earred owls, barred owl, great grey owl. They also use their faces to hear with facial disks (like satellite dishes, move sound toward the ear openings). Owls also have very small these - beaks/bill so sound waves don't reflect off the beak (meathook tipped for tearing apart prey) A wide head on an owl provides - horizontal sound separation. Asymmetrical ear canals then provide vertical sound separation. Both of theses are auditory crosshairs for accurate pinpointing of sound
