Number of Decoys

I have been out the past couple of mornings and had too much time to ponder too many things.

Here's one. How can anyone conduct any credible research into how many ducks to put out in a spread? How would you compare one time to the next? I would think there would be far too many uncontrollable variables to make the data useless. Variables such as wind speed, wind direction, temperature, overcast verses sunny, sunrise/sunset times, humidity, and so on. I typically hunt smaller water. I haven't seen a difference in hunting success if I put out 3 decoys, 12 decoys, 30 decoys. Haven't seen a difference if I put out more hens or drakes. Turn the heads to the left or to the right. Weights on the butt end of head end.

Just curious if there have been any scientific studies with reproducible results on something like this.

No rhyme or reason. Match what you are seeing the ducks doing in the wild so you look natural. For me that means small decoy spreads in October, and big ones in November and December. Except when it doesn't. If the ducks are looking but not committing, change something. That's more likely to be moving decoys or taking some away than adding more.

After that, superstition rules. My rules include that:

(1) You should always have an odd number of decoys.

(2) IF you put out multiple species, it should be an odd number of each species, and a total that is an odd number. This means you need an odd number of species, too.
--Corollary: Because they are so closely related, Rule #2 does not apply with respect to black ducks and mallards, which can be mixed as though they were a single species, or counted as two different species, whichever works better. (This is my get out of jail free card, but when I count the blacks and mallards as two species, it must be odd numbers of each.)

(3) Except for mallards and black ducks, which I see together on the water in the wild, I always separate my species a bit into groups.


More arcane superstitions could certainly be added. Prime numbers? Perfect squares? Only decoy numbers from the Fibbonacci sequence?

Just in case you might be tempted. https://www.mathsisfun.com/numbers/fibonacci-sequence.html
 
If there is such a thing as a study regarding your questions, I'm inclined to call quackery. As you said, way too many uncontrolled variables. Match the number and type of decoys to the number and type of birds using the area. The caveat being, always deploy an odd number of decoys, and you'll be good. [smile] That, and a good dog in the blind.
 
Wow, now I am really going to have to plan this out. I always leave the house with full slotted bags. For years that was always 6, or 12 slot bags, but this yr I added a couple 9 slot bags, but 2 of them. I plan to use 3 12slot bags and 2 9slot bags in the Scaup, but then may add a few swans that are not in bags. I think I will need to create a spreadsheet to ensure I have enough species to maintain the odd numbers in even numbers of slots???!!!! Maybe I will just add a real odd decoy, like a grebe to the boat and always have an out?
 
I have a different approach altogether, depending upon what kind of hunting I'll be doing:

Layout hunting -- number of decoys that will fit comfortably on 10 mother lines. Somewhere around 100.

Sneak hunting -- number of decoys that will fit into the sneak boat. Usually around 5 1/2 dozen in the 18 footer; 8 dozen in the 21 footer.

Mallard hunting with canoe -- number of decoys that will fit into the mesh decoy bag I've been using for the past few years. Yesterday it was 29.
 
I need to get a grant to conduct this research for the next 20 years....
 
I used to think that sometimes fewer was better. However, I've adjusted my thinking. I think sometimes 8-10 is as effective as 36. However, if you are willing to put in the effort to deploy say 100, they become much more magnetic, even if you are hunting in an area with few ducks. Also, people say match what you are seeing locally, but those birds weren't local for much of their life. They've seen thousands of live birds at refuges all over the country.
 
We have a 90 acre pond with three blinds in a rough line. We put out about 1,000 that snake between the blinds. Works great.
 
I've adjusted my thinking on this. I used to think more was better but now tend to favor fewer. I primarily hunt small water (small creeks, small ponds) and will put out between 9 and 15. I do tend to favor an odd number and I do group species.

The primary thing is being where the ducks want to be. Nail that part and decoy numbers/placement becomes very secondary.
 
As many as you can. For me, that's either 11,13,15 cedar blocks in a sneak in the tidal marsh. 13 is not unlucky in decoys, it's actually a good jinx. I do like to put out the ducks that are most prevalent in the area I hunt and am targeting. But like Kris said, the more the merrier.

I had forgotten the "it can be any odd number EXCEPT 13" rule. Also, although 2 is not an odd number, it is a prime, and therefore acceptable. For some highly mobile hunts, like sculling over decoys, a pair of black ducks is a the perfect "spread".
 
This question brings back memories of many flooded timber hunts I had that were limits or near limits where I set out ZERO decoys, which, Jeff, happens to be an even number and not a prime. These were spots I scouted and knew ducks were hitting at first light. Come to think of it, I wonder if there is any other place besides in a timber hole where this can happen. Around here I think not.

Ain't how many.

Where, and what waterfowl being hunted?

Over water I would guess for ducks.

Black painted Bleach bottles work fine at times. A few handmade decoys, different poses work magic at other times.

I have found that Quality Decoys work better than quantity. Proof is in the pudding over a long span of time.


Timber hunting. Few to no decoys, just keep yer boots making lotta WAVES and do not shoot at large flocks. The brighter the day the better.

The birds see decoys from the top, not the side (most times). Decoy judges do that....


my 2 cents

2 black ducks is a good rig in the right place. I had not considered the significance in being a prime number, but agree that 2 decoys can be good, particularly for wary black ducks. That is the only case in which one should use an even number, because no other even number is prime. Just more proof of the even/odd question.

Good post, Mark. We had a stretch of time down here when there was an abundance of smart weed. It lasted almost 5 years. In that time I would find a nice honey hole with smart weed and some grassy patches. Over those years I would normally use anywhere from 11 to 33 decoys and Greg, the only even number I would put out was 2. I did enjoy what you had to say, by the way. Now at the age of 81, I normally use 5 to 7 decoys. Most of the time I will use 3 teal along with 2 or 4 big ducks. My decoys are always placed up to 15 feet from shore but no farther. That is what my retrieving stick can get without me having to step in the mud.

Anyway, since puddle ducks are gregarious, sometimes those numbers are enticing to incoming birds. If I am hunting the Rio Grande I normally always tried to set up close to a sandy island or a very shallow area and then I always incorporated the use of the full body decoys like you use in a corn field. When placed on a stake a small breeze would keep them moving all the time. I made darn sure that they were always placed in the shallow water because that is what I observed the ducks doing. They seemed right at ease standing in 2 or 3" of water but I never saw many of them sitting or standing on the sand.

On the pond that I used to hunt that was not too far from the Rio Grande, I once found about a 10' branch that was about 8" in diameter.
That year the rancher brought in his dozer and cleaned all the weeds out and at the same time instead of some dandy shallow water he dozed out some more material that ended up with the pond being about two to three feet deep. That time I took my battery operated drill using a 9/16th bit. I drilled about a dozen or so holes with some closer together than others and once again used those life sized decoys with short pieces of 1/2" wood dowels holding up the decoys. Some of the log was slightly submerged and I used full body feeding decoys there. It worked well because it gave the look that the pond was shallow and inviting to the ducks. With a few of the old style Herter model 72 decoys that do such a great job with hardly any breeze at all, it all worked just fine. Just so you know I used two 48" wood dowels to hold the log in place.

Finally the biggest change I have made in the past decade was to begin using more and more black ducks. If there ever was a black duck in New Mexico it was because the poor bird got totally lost. When I had decoys needing paint I just went to the hardware store and bought cans of flat black spray paint. Yup, even the beaks got painted. They worked just fine. Back around 09 I bought a half dozen black duck decoys from Cabelas and along with my Mexican duck from Steve, things seem to work just fine. Now I need to say just one thing. I live in an area that has very few clouds. Normally my best days are those that we call "severe clear". You can get away with beaks painted black etc. But if the area where you live has lots of clouds, that is when ducks seem to be darn particular where they go. Some of the folks have talked about good looking decoys. Yes, I am sure it works. I just don't hunt on cloudy, rainy or snowy days.

Mark, your environment normally will dictate the number of decoys that you use.

Have you ever tried leaving your decoy bag on the shore line next to the water. I did. I even left my decoy bag in the decoy sled/boat on a sandy island just a few feet from my decoys. Never ever had birds flare because of it. You should also try sitting in the wide open with maybe your back up against the stalk of a wild sunflower plant. Just don't move. It is amazing what happens. Fun, too! Ducks don't pay much attention to inanimate objects. If you can be one its called being up close and personal. I had three different dogs that could do that and they were Chili, Habanero aka Habi and Chipotle aka Chip. When out in the open I would always have them wear camo so that their bodies would covered. After saying that I will be using a picture of Chip with no camo jacket. We were hunting teal. Almost anything goes when you are hunting just teal. The second picture is of the area where we sat. Chip could run straight ahead from where he was. We sat maybe just 6 to 8' from the water's edge.

My hunting has had to change the past 3-4 years or so. My favorite spot had an upstream dam removed which allowed tons and tons of silt to flow downstream into the area I hunted. Instead of wide, 3' creeks near the mouth, it is now either fast moving narrow creeks or slow moving, really shallow areas (6-8"' deep).

I used to be able to hunt out of my boat with a blind but the boat can't get back to the good spots to hunt so I bring a chair and haul that to where I hunt. Tried putting the chair behind a blind but just couldn't see the ducks in that location so I sit the chair in front of the blind and remain motionless as Al mentions. After the sun comes up, I may move to a more covered location.

As far as decoys. Used to bring along 15 or so and just throw them where I didn't want the ducks to land. Now that I have to carry everything, large numbers of decoys is too much. At the end of last season, a pair of mallards did the trick as when most of the other water freezes, this spot remains open and the ducks want to be there. So far this year I've benn putting out 7-8 dekes. Not much action yet as it is just too nice up here. We need weather.

Anyway, as always, use the number of decoys that seems right for the spot. I hunt with a guy who is a firm believer that the decoys have to be set out in a certain pattern. I don't agree as I don't think I have seen puddlers float in a "J" formation. Don't think I have seen any divers do it either.

Anyway, gets lonely waiting for the sun to rise and the mind wanders. Stay tuned for next hunts wandering mind question.

Every hunt? Count me out :)

No way, that would be uncivilized! We put them out just before floodup and leave them out all season. Just walk out the gravel path and jump into the pit and start hunting.
 
My thoughts are 7 or 70. There are to many spreads with 12 to 30 decoys in them. Birds see these spreads all the way down the flyway and I feel that they just avoid spreads of this size after being shot at enough. I typically will use 2 or 3 mallards and a handful of widgeon. Plus the smaller amount of decoys allows you to move easily if the birds want to be somewhere else. I hunt mostly on the Columbia river and sometimes moving 100yards to another spot can make a bad hunt a great hunt. In my opinion, Being were they want to be is most important. When that can't happen then decoy placement and decoy movement become much more important. I flare more birds because I am all antsy in the pantsy looking around, standing up, sitting down, adjusting my 5 decoys for no reason, going for a walk. Not because of my decoys....

I like the 7 or 70 approach. Some days 7 is too many, sometimes 70 is too few, but I like it. Really in most cases if you are on the "X" just a few is enough.
