If a large number of your birds are sick or dying
Contact the Wisconsin Department of Agriculture, Trade, and Consumer Protection (DATCP)
If you notice dead wild birds
Contact the Wisconsin Department of Natural Resources (DNR)
Observations of sick wild birds are important as Wisconsin is in the Mississippi Flyway for migratory fowl, thus increasing the wild bird traffic in our area.
⚠️ HPAI has already been detected in a sandhill crane in Dane County in 2025.
