Several times while rifle hunting, I've been sitting in a box blind and had birds fly inside the stand, which would scare the #@$%&*# out of both of us. I even had a large owl land in the window that I was looking out of, he landed approx. 1 ft. in front of my face. I then packed my stuff up and climbed down and decided that the birds just wanted that stand more than I did and they could have it.
