The bird flu outbreak, which began in North America in late 2021, has severely impacted wild bird populations. Since then, over 170 species, including ducks, geese, gulls, owls, and eagles, have been infected. The U.S. Agriculture Department reported more than 12,000 confirmed cases, but experts believe the real number is much higher since many dead birds are never tested. Migratory birds, like geese and eared grebes, have been hit hard. For example, one outbreak in Utah killed 15,000 to 25,000 birds. Seabirds, which nest in large groups, have also faced serious losses. However, songbirds such as Northern cardinals and blue jays have shown more resistance because they tend to stay in smaller groups. To help reduce the spread, experts recommend removing bird feeders for those who keep backyard chickens. Keeping feeders and nesting boxes clean is also recommended. Keeping feeders and nesting boxes clean is also recommended. Researchers have started vaccinating endangered California condors, but this method is not practical for most wild birds. Instead, experts suggest protecting habitats and reducing environmental threats. Encouragingly, recent data shows fewer bald eagle infections, suggesting some may have developed immunity.
