Jer,I have to say you answered this question very well and with good advice based on puddlers. I am not a fancy educated waterfowler but I seem to shoot many more birds than most of the folks I talk to at the boat landing. My advice would be very similar.
I would add just because one day you shot a bunch of birds in the place you plan on going means that you will shoot a bunch everytime you go there. I rarely if ever hunt the same place twice. Watch the birds. If you see the area they appear to be landing in go to it. Sitting all day in a dead spot never gets any better, the time it takes to move will add up in birds. Second I never- ever- use mojo’s or any rotating wing decoys. Occasionally a jerk line if the water is calm, definitely a shaker decoy butt or two just to get some ripples on the water. The rotating decoys are not an advantage, they will bring in a hen or two but never have I seen them work well on flocks (my experience). Good calling and a great decoy set works the best. As far as decoy sets, again look at the birds. I frequently stop at the refuges around my area to see how birds are currently reacting. I look at them and note the conditions, IE calm winds out of the south I observe the birds all spread out and no real assembly to the flock, if that’s the weather I have, that’s how I set my deeks. If I go to the refuge say on a real windy day look at the birds and see they are in tight bunches with little room inbetween, that’s how I set my decoys on a windy day. You can learn more from observing birds in the area you hunt than you will ever learn from a book or TV show.
I promise if you choose a spot based on its looks, prepare for a long day. I was not taught how to hunt, I learned and I was self taught. I spent many days of frustration in 30+ years of hunting because I was in a great looking spot. Study your game and you will be so much more successful. Sunday I hunted a new place I’ve never tried, Saturday I watched 100’s of Mallards land there throughout the day. Me and My partner took 8 Mallards in less than 10 minutes of opening. Never called never did anything special. Put about 24 decoys out just like I saw the birds on Saturday. Every bird we shot was decoying less than 15 feet from the blind and every bird dropped right in our set. At day break we had over 200 birds trying to land in our tiny little set.
Nothing is fool proof but I believe strongly that your experience and future hunts success will improve if you just take some time to watch whatever it is you are after. I’m going out tomorrow morning. I’m going where I saw some birds land and I know its not iced over yet. I’ve never hunted it but I’ve seen birds there. I’m going to use about 18 decoys. I have a good feeling about it. Its going to be a cold one but I have feeling I won’t be out long.
