Pennsylvania has become the epicenter of a devastating avian flu outbreak that has killed thousands of birds across the United States, according to Inside Climate News. The outbreak threatens wildlife populations that have taken decades to recover, including bald eagles that returned to Philadelphia for the first time in 200 years as recently as 2007.

The avian influenza strain poses significant risks to bird populations that serve as crucial indicators of ecosystem health and climate resilience. Birds play essential roles in carbon cycling, seed dispersal, and pest control that help maintain forest carbon storage and agricultural productivity.
