I agree as well that you should get yourself a blind ,I use one now and it make's it much easier than you would expect .But it can be done without a blind as well but you'll need lot's of cover and you'll need to draw much sooner ,because the bird's have the best eye's of all and spot any movement ,just be sure to draw as soon as he start's to get close ,not when he's right in front of you. It also help's to practice in different position's as well as other's have already said ,but you can pull it off as long as you can draw behind cover before the bird step's out .Good luck
