sometimes you can beat them at their own game. wait in a tree. ive done that and seen a few come my way. you dont even need to be all camo'd out. i did it in jeans and a white shirt before.

when they orbit around the tree to get away from you, tie a string to a bush or branch on one side, move to the other side then pull the string so he thinks you are on the other side and he will move to your side and you can shoot.
