Suspected Bird Flu Decimates Hundreds of Ducks Along Chicago's Lake Michigan Shore

Conservationists report a surge in red-breasted merganser deaths as officials warn of potential spread to other species.

Around 200-300 red-breasted mergansers have been found dead or sick along Lake Michigan's Chicago shoreline in recent days, with bird flu suspected as the cause.
The outbreak has also affected other species, with reports of infected hawks, owls, and even a flamingo and seal at Lincoln Park Zoo succumbing to the virus.
Experts are concerned about the virus's potential adaptation to mammals, though human infections remain rare, with 67 cases and one death reported in the U.S. since 2024.
Residents are being advised to avoid contact with sick or dead birds, and proper precautions, such as wearing gloves and masks, are recommended for safe disposal of carcasses.
The virus thrives in cold temperatures, raising concerns that the outbreak could persist and potentially spread to additional species in the coming weeks.
