Songbirds are mysteriously dying across the eastern U.S. Scientists are scrambling to find out why

Jennifer Toussaint, chief of animal control in Arlington, Virginia, can’t forget the four baby blue jays. In late May, worried residents had delivered the fledglings to her clinic just outside of Washington, D.C., within just a few hours. Each was plump, indicating “their parents had done a great job caring for them,” Toussaint says. But the birds were lethargic, unable to keep their balance, and blinded by crusty, oozing patches that had grown over their eyes.
Toussaint and her staff soon reached a gloomy diagnosis: the jays were the latest victims of a mysterious deadly disease that had emerged in their area just a few weeks earlier and had already killed countless wild birds. There was no known treatment, so they euthanized the jays. “It was difficult to feel so helpless,” Toussaint recalls.
