MADISON, Wis. – The Wisconsin Department of Natural Resources (DNR) today announced that data is now available from the annual spring survey of breeding waterfowl. The survey indicated stable population numbers and habitat conditions for migratory birds.
The data from this survey is used as part of the overall survey of breeding waterfowl in North America, and the information helps the DNR make management decisions about waterfowl in Wisconsin. The survey has been conducted annually since 1973, except for 2020 (due to the pandemic). Survey results are best interpreted as trends over several years rather than year-to-year comparisons.
Surveyors estimated the state’s 2025 breeding duck population at 564,693 birds, a 7% increase from the 2024 estimate and 26.9% above the long-term average. The 2025 mallard breeding population estimate is 149,568 birds, 2% higher than 2024 but lower than the long-term average. Wood duck populations decreased 1.8% from last year but remain 5.1% above the long-term average.
The Canada goose population estimate is 8% lower than in 2024, yet it remains significantly higher than the long-term average.
