The current outbreak of avian influenza is having a significant impact on bird populations in Maine and beyond. The disease was first detected in a non-commercial backyard flock of chickens in March 2022, and has since spread to commercial poultry and wild birds. Gulls, in particular, have been hit hard locally, with hundreds of dead birds found on nesting islands. The Christmas Bird Count revealed a significant decrease in American herring gulls and great black-backed gulls, indicating the impact of the disease on wild bird populations.
In addition to gulls, other species such as Great Skuas have also been affected by avian influenza. Millions of birds were lost in UK nesting colonies, with a 76% population decrease. The disease spreads through feces, saliva, and mucus, and has been detected in ducks, geese, and even predators that feed on sick birds. Despite the threat, backyard birds like chickadees and woodpeckers are unlikely to contract the disease, so there is no need to stop feeding them.
To help protect wild bird populations, individuals can keep their cats indoors, treat windows to prevent collisions, and support native plant habitats. Maine Audubon is providing resources and guidance on how to help birds during the avian influenza outbreak. If individuals encounter a sick or dead bird, they are encouraged to report it to Maine Inland Fisheries and Wildlife.
As the avian influenza outbreak continues, it is essential for individuals to take precautions to protect both wild bird populations and themselves. By following the guidance provided by organizations like Maine Audubon, individuals can help minimize the impact of the disease and support bird conservation efforts.
