Botulism linked to more than 80,000 bird deaths

More than two dozen common loons have been found dead at a beach in northern Michigan.

Good Harbor Bay beach is at Sleeping Bear Dunes National Lakeshore in Leelanau County. Officials believe the birds were likely killed by type E botulism and washed ashore.

Botulism has been linked to more than 80,000 bird deaths around the Great Lakes since 1999.
