i went for a walk while hunting the other day(slow day) and i got to the pond next to the pond the other guys were hunting on and they had some mallards circling hard. I Started calling like crazy just for kicks, thier mallards dove straight towards me and circled me about 4 times and then went down on the pond i was by. they got up and i shot and then they went down in front of the other guys. I bet they were mad at first
