Turkey hunting one morning years ago, wasn't having any action and then heard a gobble from the other side of the farm in corner where they are frequently known to strut. Eased my way up to said corner on an old mossy logging road, the perfect way to quietly close the distance. 50 yards out through the brush I could see him, strutting and facing directly away from me. The dark underside of his tail highlighted by the light brown tips. Gave a few yelps, but he had gone silent.
Creeped 20 yards closer and peaked up. Still there, still strutting and facing away. Still silent. Still some brush in the way.
Closed 10 more yards. Couldn't believe he was still there and STILL strutting facing the other way. Gave a purr, but no reaction. Close enough to shoot, but I wanted to see his head, and something just felt a little off.
Pulled out my binos, wondering why this bird wasn't reacting to my calls, or just pivoting and moving.
Well... the "tail" (dark underside and light colored tips) was actually the bottom end of felled tree trunk.
The upper round half of the trunk, which was all I could see, was just about the exact size as a gobbler fan. The light tips, were the lightly colored pieces of bark in a perfect semi-circle. Imagine looking at a cross cut section of the trunk. I was never close to even aiming at it, so I didn't have any worries that I would have made a dangerous shot, but man did I feel stupid for having stalked a tree trunk. Don't know where the real gobbler ended up that time.
