Wounded rabbit mouth call and a mouse squeaker. 3M double tape the squeaker to the forestock of your gun so you don't have to move to work it. If your shotgunning them you'll need them close so movement needs to be kept minimum. Ghillie suit is a tremendous advantage too. Watch your back. Them SOB love to follow the wind and circle around you first like a yote.
