The breast meat had been harvested.
The Minnesota Department of Natural Resources said it is investigating who discarded more than a dozen geese carcasses in a ditch along a busy road near the North Dakota state line.
WDAY-TV reports the geese had their breast meat harvested before their carcasses were tossed in Oakport Township in Minnesota. Canada goose hunting season is open in some parts of North Dakota but the season didn't start in Minnesota until Sept. 1. The carcasses were found in August.
Tara Goehring said she spotted them near a busy road in a pile not far from where she lives.
"I don't know if they were legally shot in North Dakota and dropped off here in Minnesota or if they were poached," she said.
The DNR has removed the most of the carcasses but there's still a stench, even though a mower has been through the area.
It isn't illegal to dump the carcasses but it is considered littering. The DNR has said disposing carcasses on private property is OK, but not in trash containers or public roadside ditches.
"It was very irresponsible to dump there," Goehring said.
