Got my new North American Whitetail mag. this week and was reading about the buck growl. If you don't get the mag., the buck growl is a sound that a highly aroused,agitated buck makes that is seldom herd by hunters or recognized as a deer vocalization. I heard one do it a couple of years ago. I had my wife with me and we were having a lot of mature buck activity when we heard what sound like a dirt bike in the woods behind us. It was avery loud, long and drawn out growl sound. I told my wife that the big boy must be tending a doe in there, we never did get to see him though. Another sound that I've heard came from a doe while being harassed by a buck, I heard this twice in one week by different does. It sounded almost like a bark, almost exactly like what the veloco-raptors on Jurrasic Park sounded like. It was pretty neat seeing the does do that.
