Duck decoy spread details

The key to effective decoy spreads is to make them realistic.

Increasing realism ultimately leads to more birds on your strap

Larry Reynolds criss-crosses the Louisiana coastline multiple times each fall — cruising at 100 knots with a bird’s-eye view from just 125 feet up, estimating the number of ducks that have arrived in the state’s ag fields and coastal marshes.

The waterfowl study leader for the Louisiana Department of Wildlife and Fisheries since 2008, Reynolds spends several days each fall in the seat of an airplane staring out at a variety of habitat during those annual surveys.

As you might expect, in even the slowest of years, he sees thousands and thousands and thousands of birds — and observes how they move about and interact on the landscape.

In the course of estimating the number of birds calling the Bayou State home each winter, the biologist also comes across hunters’ efforts at producing realistic decoy spreads from his seat in the plane — and well, let’s just say some are better than others.

Keeping your decoy spread looking real

“When I can look at a decoy spread and go, ‘That doesn’t look like ducks,’ I gotta believe a duck does the same thing,” Reynolds said. “Hunters have to be aware of what ducks look like on the water. They don’t universally mix around, and they don’t sit in large regular groups. When I see regularity, I know it’s not ducks. Whenever there is a discernible pattern, I know it’s not ducks.

“Ducks don’t sit in a ‘J,’ they don’t sit in an ‘H’ and they don’t sit in two teardrops opposed to each other with a big lump on the levee between them.”

On his 150-acre lease in the marsh in Cameron Parish, he keeps things pretty simple for the opening of the season.

“I start out in my biggest pond with a pretty good spread of 70 decoys,” Reynolds said. “Typically, I start out with three dozen teal decoys, six hen mallard decoys to represent mottled duck pairs, then I’ll use a dozen or so pintail decoys out in the more open parts of the ponds.

“I’ll throw in another two dozen or so gadwall decoys in small groups.”

As the season progresses, Reynolds drastically downsizes his spread and seeks out smaller ponds on his lease as dabblers pair up and become less social.

“By the time the season ends, I’m hunting with typically a dozen decoys, and that will include a couple of hen mallard decoys, five teal decoys and couple of mallard decoys,” he said. “So the adjustments that I make on my little patch of ground are primarily based on the behavioral differences of the ducks ….

“Build some irregularity into your spread to increase the realism. No matter what, you’re going to be more successful if you increase the realism.”

Spinning dekes

As for spinning-wing decoys, Reynolds says they definitely catch his eye when he flies the January aerial survey while hunters are out in the field.

“When those spinning-wing decoys are on, I can see them for miles,” he said. “They really do look like ducks flapping their wings, so I can absolutely see why they attract ducks.”

But Reynolds uses a spinning-wing decoy only during teal season. If you feature one in your spread during duck season, he suggests using it in moderation via remote control.

“If they’re continuously spinning, you look at that and go, ‘That’s not realistic,’” he said. “They do it in a way that becomes predictable and overdone.

“My conclusion is that anyone that just uses a plain spinning-wing decoy for the entire season has definitely got to see a reduced response, and I think they’ll probably see avoidance of their spread late in the season.”
