Just a note about turkey alertness and eyesight.

This past fall while bowhunting, 16' up, a jake came out, quartering away about 10yds. I've always heard they could see you blink, well he didn't. So I raised my shoulder about an inch. He was gone in a heartbeat!

You can't get away with any movement. Even in your blind, wear black and a black hood. Keep the windows open to a minimum. Make your move when he is behind a tree or brush, or at full strut facing away. Remember, they have something like 290deg vision with an almost non existent blind spot.
