HPAI, commonly known as bird flu, is a highly contagious respiratory disease that causes sickness and sometimes death in birds and mammals. Since December 2024, wild bird mortality cases have increased across the state, particularly among Canada geese, trumpeter swans, and scavenging birds.

The Michigan DNR advises waterfowl hunters on precautions against bird flu due to cases in wild and domestic birds, including cooking meat properly and wearing gloves when handling birds.
