The bald eagle population has slowly recovered from the impact of a pesticide that nearly drove them to extinction decades ago. But now researchers at Cornell University have found that lead ammunition continues to hamper the resilience of these American icons.

The use of lead ammunition in bald eagle habitats has reduced population growth by 4% to 6% annually in the Northeast, even as their populations soared in the lower 48 states from 2009 to 2021, according to a study published in the Journal of Wildlife Management.
