The Wisconsin Department of Natural Resources (DNR) has released data from its annual spring survey of breeding waterfowl. The survey, which is part of a broader North American study, revealed stable population numbers and habitat conditions for migratory birds in the state.
The survey estimated Wisconsin’s 2025 breeding duck population at 564,693 birds, marking a 7% increase from the previous year and a 26.9% rise above the long-term average. The mallard breeding population was recorded at 149,568 birds, up by 2% from 2024 but below the long-term average. Meanwhile, wood duck populations saw a slight decrease of 1.8% from last year but remain 5.1% above their long-term average.
However, the Canada goose population estimate showed an 8% decline compared to 2024 figures but still remains significantly higher than the long-term average.
For those interested in further details, additional data can be accessed on the DNR’s Wisconsin Wildlife Reports webpage.
