” Whitetail Survival Ears: Deer have a well developed sense of hearing.Their large ears are used to funnel sound into the ear canal. A network of muscles attached to the ear allow the deer to turn its ears in any direction without moving its head. Like dogs and other animals, deer can hear higher frequencies of sound than humans. A deer’s keen sense of hearing allows it to distinguish the sound of a squirrel hopping through the woods from the footsteps of a predator.“ http://waterandwoods.net/2008/09/anatomy-of-a-whitetail/
