I had a dominate buck one year come into the same thicket that does were visiting regularly and for 3 days straight he would enter the thicket and blow and blow!! I knew it wasn't at me because I could see into the thicket a bit and non of the deer ran off and the wind was in my face. So I wrote a deer expert about the experience and he told me a dominate buck will blow to let all the younger bucks to get the hell out and that daddy was home!
