Generally I would have to agree ....and I hunt with resource management in mind on such spots....However, there always is some place that they can be pounded, and still return day in and day out. Geese are notorious for this in my experience. We have pounded a field four of seven days, and they still want in no matter. I think ducks are more apt to move on from a pond, especially a roost location, when they get tagged too often. I have a spot where I hunt only three or four time a season...and they are almost always banner hunts. I'm actually afraid to find out if going there a couple times aweek would alter their routine. Rather not mess with a good thing!
