First, lose the burlap. If you can sit still, you don't need it and sooner or later, all that fumbling while getting it set up will cost you a turkey. If you KNOW you have birds coming to a particular spot and you have plenty of time, then take it and set up a blind. Otherwise, just use the cover that is available. I have taken birds while sitting against a pine tree in burned out woods. I was as exposed as a wart on your nose, but being set up in the right direction, sitting VERY still, and a little patience gave that bird a ride in my truck.

As for that particular bird, I would give him a week or two to settle down before I messed with him again. Their little pea-brains don't store a lot of memories and, while they learn fast from bad experiences, if you go in with a little different tactic and out think him, you'll have company on the way home, too.

Good luck!
