Wildlife Diseases

Below is a list of diseases and other health issues commonly found in Wisconsin wildlife or the DNR monitors for their occurrence. Click on a specific disease to learn more about its transmission, common signs observed in affected wildlife, management actions, associated public health concerns, and links to additional information.

You can help monitor the health of Wisconsin's wildlife by reporting your sightings of sick or dead wildlife to the DNR. To report a sick or dead wild bird, please use this survey form: Sick or Dead Bird Reporting Form. Or you can contact the Wildlife Switchboard to report a sick or dead wild mammal or wild bird by emailing or calling 608-267-0866. You will need to leave a message for the switchboard staff. In your message, please include the number of wild animals, the species (such as a raccoon or Canada goose), if they were sick or dead, the location where you saw them, and the county and your contact information. It is not necessary to report wildlife killed along roadways.
