Numerous dead ducks were found washed up on the shores along Lake Michigan's Chicago shoreline

In recent weeks, Chicago's Lake Michigan shoreline has witnessed a concerning number of dead and dying ducks, particularly red-breasted mergansers. These waterfowl, which migrate to the area during winter, have been found exhibiting symptoms consistent with avian influenza, commonly known as bird flu. The sudden appearance of these sick and deceased birds has raised alarms among local conservationists and public health officials.

The Illinois Department of Natural Resources (IDNR) has reported that, since December 3, there have been at least 144 incidents of suspected avian flu across the state. The recent thawing of Lake Michigan is believed to have contributed to the increased visibility of these affected birds washing ashore. While the virus poses a low risk to humans, officials are urging the public to avoid handling sick or dead birds and keep pets away from them to prevent potential transmission.

Impact on Chicago’s wildlife

The red-breasted merganser, a species that typically remains aquatic, has been observed exhibiting unusual behavior, such as coming onto land and displaying tremors and weakness. These symptoms are indicative of the H5N1 strain of avian influenza, which has been responsible for significant bird die-offs globally. In addition to mergansers, other species, including crows and gulls, have shown signs of infection, raising concerns about the virus's spread among various bird populations.

While avian influenza primarily affects birds, there is a minimal risk of transmission to humans. The Center for Disease Control and Prevention (CDC) states that human infections are rare and usually occur through direct contact with infected birds. Nonetheless, the public is advised to exercise caution. The Chicago Park District has deployed personnel to monitor and remove bird carcasses from public areas and urges residents to report any sightings of sick or dead birds to local authorities.

Preventative Measures and Future Outlook

To mitigate the spread of the virus, officials recommend the following precautions:

Avoid Contact: Don’t handle sick or dead birds. If contact is necessary, use protective gloves and wash hands thoroughly afterward.

Pet Safety: Keep pets, especially dogs, on leashes and away from bird carcasses to prevent potential transmission.

Reporting: Report any sightings of multiple sick or dead birds to the IDNR or local wildlife authorities.

As spring approaches, it is anticipated that warmer temperatures will help to reduce the prevalence of the virus. However, continued vigilance is essential to monitor and control the outbreak, ensuring the safety of both wildlife and the public.
