Some time ago, I read an article in Traditional Bowhunter Magazine (I believe) regarding yelping at whitetails. I don't recall who authored the article, but the hunter stated he's been yelping at whitetails for quite some time. As the story went, the author said if a whitetail were to look up at him in the tree, he would simply yelp. The whitetails nearly always immediately calm down, allowing for a shot opportunity. The author said that deer apparently can't, or don't, differentiate a difference between a 200 lb. camo clad hunter from a 20 lb turkey.
I have been intrigued with this notion since the article was published. Has anyone done this? If so, how did the deer respond?
