Bald eagles, as well as other wildlife, have been succumbing to a mysterious neurodegenerative disease in the southern United States since the 1990s. New research by the Martin Luther University Halle-Wittenberg (MLU) in Germany and the University of Georgia, U.S., identifies the cause of these deaths: a toxin produced by cyanobacteria that grow on invasive aquatic plants. The problem is potentially exacerbated by herbicides used to control those plants. The results were published in Science. https://phys.org/news/2021-03-bald-eagles.html
