So last season I learned an interesting lesson on sound localization. While sitting down for lunch on top of a Mountain we let out a bugle, it was immediately answered from a bull over 1000 yards away downhill, we replied and he came running. He literally ran up the hill and stopped 20 yards from where we were and stared at the exact spot we were sitting at when we bugled! I never knew that their sound vocalization was that spot on! It was truly one of those Holy Crap moments where you realize just how tuned their senses are.
