VIRUS TAKES TOLL ON WILD BIRDS
- Since late 2021, bird flu has spread through North America, devastating poultry and dairy farms and infecting more than 170 species of wild birds, leading to soaring egg prices in the United States Part 1, Part 16, Part 19.
- The U.S. Agriculture Department reported that over 12,000 individual birds have tested positive for the virus, but Bryan Richards from the U.S. Geological Survey's National Wildlife Health Center notes that this is likely an underestimate since most dead birds are not tested Part 1, Part 3, Part 17.
- A significant bird flu outbreak in early February near Great Salt Lake killed between 15,000 and 25,000 migratory eared grebes, while scientists also documented an unusually high number of eagle chick deaths during the first breeding season after the virus appeared Part 2, Part 20.
- While songbirds like cardinals, blue jays, and chickadees can become infected, Michael J. Parr, president of the American Bird Conservancy, suggests their populations fare better because they don't gather in large groups, and the risk of spread to people from bird feeders is very low Part 4, Part 17, Part 21, Part 22.
- Despite initial high mortality among eagles, likely from consuming infected ducks, researchers like Bryan Richards and Dr. Dana Franzen-Klein are seeing positive signs of rebounding eagle populations, possibly due to acquired immunity in surviving birds Part 5, Part 14, Part 16, Part 23.
