Quarter Century After Arkansas Eagle Deaths, Researchers Identify Killer

Apr 6, 2021

In the mid-1990s, dozens of bald eagles started dying at DeGray Lake after exhibiting neurological symptoms like stumbling, flying into cliffs and stooped wings. A quarter century later, researchers have identified the specific pollutant that causes blue green algae to make a novel toxin that then leads to brain lesions in the birds. Their research was published last month in Science Magazine.
