A widespread bird flu outbreak has affected over 170 species of wild birds in North America, including ducks, geese, gulls, and owls. While the outbreak is a concern, experts say that the threat to humans is currently low.
The virus has been detected in more than 12,000 individual birds, but this count is likely an underestimate as many dead birds are not tested for the virus. Some bird species, such as dabbling ducks and songbirds like Northern cardinals, are more susceptible to infection due to their social behavior and migration patterns.
Symptoms of bird flu in wild birds include lack of coordination, inability to fly, and respiratory distress. If you encounter a sick or dead bird, experts recommend taking precautions and avoiding direct handling. Instead, wear gloves and a mask if you must handle the bird.
Backyard bird feeders are generally considered safe, but experts recommend keeping them clean regularly and not feeding backyard chickens if you also have a feeder to prevent possible transmission of the virus.
The outbreak has had an impact on some endangered bird species, including critically endangered California condors. However, vaccination programs like those implemented for these birds are not feasible for most wild species.
Instead, scientists focus on protecting habitats and reducing other risks that species face, such as exposure to pesticides or lead ammo. Bald eagles, which were once considered critically endangered, have seen a decline in confirmed infections from 427 in 2022 to 48 last year. This may indicate that some eagles have acquired immunity to the virus.
While the outlook for many bird species is concerning, there are signs of hope. The number of bald eagles migrating through northern Minnesota has increased significantly, and researchers are monitoring the situation closely.
In summary, while the bird flu outbreak is a concern, experts emphasize that backyard bird feeders can be safely used with proper precautions. However, it’s essential to prioritize protecting habitats and reducing other risks to help vulnerable species survive.
