ST. PAUL – Minnesota’s spring breeding waterfowl counts were at or below long-term averages for several species that nest in the state, the Department of Natural Resources reported Monday.

The DNR uses data from its spring waterfowl counts to produce population estimates. The 2022 breeding population estimates are:

  • Mallards: 231,000, which is 19% below the 2019 estimate and unchanged from the long-term average.
  • Blue-winged teal: 161,000, which is 28% below the 2019 estimate and 24% below the long-term average.
  • Other ducks, excluding scaup, (such as ring-necked ducks, wood ducks, gadwalls, northern shovelers, canvasbacks, redheads and buffleheads): 175,000 which is 6% below the 2019 estimate and 3% below the long-term average.
  • Total breeding duck abundance (excluding scaup): 567,000, which is 18% below the 2019 estimate and 9% below the long-term average.
  • Canada geese: 115,000, which is similar to the 2019 estimate and 27% below the long-term average.
  • Trumpeter swans: 25,000, which is a new record high for the population. Survey methods for swans differ, and a long-term average is not available. 

Overall, it was a very late spring across the state, especially in the north. It is likely that some blue-winged teal, a species that migrates relatively late in the spring, were still south of Minnesota when the survey began. As a result of the late spring, nesting effort and the number of young produced is expected to be below average for both ducks and Canada geese.

Minnesota’s early teal season opens Saturday, Sept. 3, and continues through Wednesday, Sept. 7. The early Canada goose season opens Saturday, Sept. 3, and continues through Sunday, Sept. 18. The state’s youth waterfowl hunt is Saturday, Sept. 10, and Sunday, Sept. 11, and the regular waterfowl season opens Saturday, Sept. 24.

What to read next
The angler is one of two men busted at the Lake Erie Walleye Trail tournament on Sept. 30. They would have walked away champions, if the event organizer, Jason Fischer, hadn’t decided to take a closer look at their catch.
On the St. Louis River Estuary, diehard angler Pam Zylka catches everything from sturgeon and walleye to drum and bass.
The first reference I found to house finches in the Herald’s online archive was in 1989, when Milt Sather called about a house finch he’d seen in Greenbush, Minn. The column about the sighting was printed Nov. 2 that year.
