Though most recognized for its devastating impact on poultry, the avian influenza virus (bird flu) has also rippled through Minnesota’s diverse bird populations, raising concerns about the impact on local ecosystems.
Waterfowl and shorebirds, unlike raptors and scavengers, possess a higher resistance too the virus. They can often carry it asymptomatically, acting as silent carriers.
Dr. Cori Franzen-Klein, a veterinarian and disease specialist, explains, “So when the virus kills off large numbers of waterfowl, it typically signals a new mutation that makes it more harmful to its hosts.” This observation highlights the virus’s constant evolution and its potential to pose a greater threat to birdlife.
Raptors at Risk?
raptors such as eagles and owls primarily contract the virus through consuming infected waterfowl carcasses.While localized declines in eagle populations have been reported, particularly around Lake Michigan, overall raptor numbers in Minnesota appear stable.
Seth Goreham, a wildlife research manager for the Minnesota Department of Natural Resources, stated, “as 2022, we’ve seen some localized comments about bald eagles taking a hit. Especially over in the Lake Michigan area populations may be down. But we haven’t seen anything in Minnesota, at least, that would indicate there was a major population hit.”
Focus on Poultry and Livestock
The primary concern surrounding avian influenza has remained focused on its impact on poultry and livestock. Sence 2022, the virus has decimated poultry flocks nationwide, resulting in the culling of approximately 150 million birds.
The U.S. Department of Agriculture has compensated turkey and chicken farmers with over $2 billion to alleviate the economic burdens imposed by these losses. Minnesota has been particularly hard hit, with over 9 million birds culled within the state.
Moving Forward: Monitoring and Mitigation
continuous surveillance and proactive measures are crucial to understanding the long-term effects of avian influenza on wildlife. Boosting the immunity of vulnerable bird populations, restricting access to potential infection sources, and promoting responsible wildlife management practices are essential steps to mitigate the virus’s impact.
The current situation underscores the interconnectedness of wildlife conservation, public health, and agricultural practices. By working collaboratively and implementing informed strategies,we can strive to safeguard Minnesota’s avian biodiversity for generations to come.

Bird Flu’s Impact on Minnesota’s Wildlife: A Conversation with Experts
Archyde sits down with two prominent figures in Minnesota’s wildlife conservation and research community to discuss the impact of avian influenza on the state’s diverse bird populations and ecosystems.
Joining us today are:
- Dr.Cori Franzen-Klein, an experienced veterinarian and disease specialist.
- Seth Goreham, wildlife research manager for the Minnesota Department of Natural Resources.
Q: Dr. Franzen-Klein, can you explain why waterfowl and shorebirds are ofen referred to as ‘silent carriers’ of bird flu?
Dr. Cori Franzen-Klein: “Certain species of waterfowl, like ducks and geese, and shorebirds can carry the virus asymptomatically. This means they can host and shed the virus without experiencing any symptoms or ill effects themselves. They essentially act as vectors, facilitating the spread of the virus to other birds. This silent transmission can make it arduous to track and mitigate outbreaks.
Q: Seth,how does the virus reach raptors like eagles and owls,and what are the current observations regarding their populations?
Seth Goreham: “Raptors primarily contract the virus through consuming infected waterfowl carcasses,especially during fall migrations when bird populations congregate. While we’ve seen localized declines, especially around Lake Michigan, overall raptor numbers in Minnesota appear stable as of 2022. However, we’re closely monitoring the situation.”
Q: Given the devastating impact on poultry and livestock, what are the key priorities in moving forward to protect Minnesota’s avian biodiversity?
Dr. Cori Franzen-Klein: “Prevention and early detection are crucial. This involves continuous surveillance, boosting immunity through vaccination, restricting access to potential infection sources, and promoting responsible wildlife management practices. Collaboration across sectors – wildlife conservation, public health, and agriculture – will be vital to safeguarding Minnesota’s birdlife.”
Q: How can our readers help support Minnesota’s avian biodiversity amidst the bird flu threat?
Seth Goreham: “We encourage everyone to report sick or dead birds to the Minnesota Department of Natural Resources to aid in our surveillance efforts. Public awareness,responsible pet ownership,and supporting conservation efforts can all make a significant difference.”
