Mike Wec was having a tricky morning.
The Massachusetts marsh he was searching on Dec. 15 had frozen over regardless of the wind, and breaking 75 yards of ice simply so he may paddle to his spot earned him sweat-soaked layers and a brand new leak in his waders. Wec had simply sufficient time to throw out his decoys — mallards to the correct, black geese on the left — and get settled.
At authorized mild, the 37-year-old seen a number of geese within the distance and gave a pair quacks. Three birds turned his method, then cut up at his greeting name, with a pair of mallards breaking proper and the third committing.
“It regarded like a hen mallard or a hen black duck, and her stomach was tannish,” says Wec, who often expects a mixture of mallards, black geese, and some geese that point of 12 months. “She cupped her wings and got here into the black duck decoys.”

He shot as soon as and dropped the duck on the water. Assured it wasn’t going wherever, he waited and killed the subsequent single that got here in, a drake black duck. Then he acquired into his kayak.
“I paddled about 20 yards previous the primary duck and glanced at it and I’m like ‘Wow that may be a mild coloured duck.’ It flew like a mallard and regarded like a mallard or a black duck, so I had a sense possibly it was a farm-duck blended mallard. I picked up the black duck and got here again and picked up the [white] duck.”
Wec went on to shoot a greenhead and a woodie — one other shock given the lateness of the season. Lastly, he shot a banded greenhead and known as it a morning, only one chicken wanting his restrict.
“As I’m sitting there,” says Wec, “I’m additionally considering, ‘What do I’ve right here and I’m I authorized?’”
Wec put the banded drake and what he regarded as the “blond mallard” on the passenger seat and known as his spouse, Ashley Wec.
“I knew I had one thing particular and I knew I needed to wrap it and put it within the freezer,” says Wec. “I‘m like, ‘I don’t know what that is, and I’ve been advised to mount so many birds earlier than and I haven’t. That is the chicken I’m gonna mount.’ So she’s like, ‘Properly can’t they DNA check it?’ and I’m like, ‘I doubt it.’”
Undeterred, Ashley carried out a fast Google search and turned up the College of Texas at El Paso’s duckDNA challenge, a brand new pilot program for 2023 designed to gather genetic information on wild waterfowl. This system is especially within the westward unfold of game-farm mallard genes in wild duck populations.
So, Wec reached out. And though duckDNA functions had been closed on the time, the images of the blond duck had been intriguing sufficient to researchers that they despatched his taxidermist a vial for amassing a tissue pattern (on this case, from the tip of the duck’s tongue).
Now, about 5 months later, Wec has acquired the outcomes of the DNA check. The white chicken was a hen, and one hundred pc American black duck. In different phrases, there was no hint of game-farm mallard and even lineage from old-world geese launched from Europe years in the past. In line with this system and its associate, Geese Limitless, that is the primary verified occasion of a leucistic, absolutely wild American black duck.
“This can be a enormous showcase of what duckDNA offers to hunters and scientists in cooperation at a stage we’ve by no means had earlier than,” Dr. Phil Lavretsky, who leads duckDNA, advised DU in an announcement. “No extra assumptions and biases, there isn’t a hiding DNA.”
Leucism is an inherited trait that ends in lack of pigmentation. In birds this will vary from just some white feathers to all-white plumage, based on DU. Leucistic geese retain regular eye shade and imaginative and prescient (in contrast to albino birds). Beforehand hunters and even researchers have solely speculated that geese with the looks and coloration of Wec’s white duck had been leucistic mallards or wild-domestic hybrids.
In its first season, duckDNA examined 721 genetic samples from geese submitted by 309 hunters in 47 states. Evaluation of these samples revealed 19 completely different hybrid combos, together with the next hybrids:
- Wild mallard x game-farm mallard
- Wild mallard x American black duck
- Wild mallard x American wigeon
- Wild mallard x gadwall (known as Brewer’s geese, these are the results of a male gadwall breeding a feminine mallard)
- Wild mallard x wooden duck
- Florida mottled duck x wild mallard
- Muscovy x wild mallard
- Home goose x Canada goose
Researchers even recognized three-species hybrids, which had been the results of hybrid duck breeding with a species unrelated to both of its dad or mum species. One triple hybrid included a duck with wild mallard, game-farm mallard, and Mexican duck genes. (You could find the complete record of the 2023 to 2024 hybrids right here.)
“Analysis from the College of Texas at El Paso has revealed that over a century of game-farm mallard releases within the Atlantic Flyway has led to widespread hybridization with wild mallards,” experiences DU. “Different research have uncovered potential variations in behavioral, physiological and ecological traits between game-farm hybrids and pure wild mallards, which can influence replica, actions and duck distributions throughout their vary.”
