My first year to bow hunt about 25 years ago I was in a lock and got busted by a squirrel. He climbed out on a limb just out of reach and was barking like crazy. I was trying to figure out how to shut him up when out of no where a large hawk flew by me and grabbed him. That shut him up quick but I nearly ran off the edge of the stand, lol. Like others have said, I felt the wind off it's wings but never heard it.
