A bird flu outbreak in North America has devastated poultry and dairy farms, driving up egg prices. But its impact on wild birds is concerning, with over 170 species infected and a recent outbreak killing between 15,000 to 25,000 eared grebes in Utah. Experts warn that handling sick or dead birds can be hazardous, but keeping bird feeders up poses little risk.
The US Agriculture Department has recorded over 12,000 individual bird cases since the virus began spreading. However, most dead birds are not tested for the virus, making the true number higher. Some species, like dabbling ducks and geese, can carry the virus with few symptoms but also shed it, infecting other birds or mammals.
Birds that migrate or roost in large flocks, such as songbirds and seabirds, are most at risk of dying from the virus. Symptoms include loss of coordination, inability to fly, and respiratory distress. If you see a wild bird acting strangely, contact your local wildlife rehabilitator instead of handling it.
Bird feeders are generally safe, but keeping backyard chickens may require taking precautions, such as removing feeders to prevent transmission to poultry. Experts recommend protecting habitats and reducing risks like pesticide exposure or lead ammo to give wild birds the best chance.
The number of confirmed eagle infections has declined significantly since 2022, with only 48 cases reported in 2023. This may indicate that some eagles have acquired immunity after surviving the initial outbreak.
