What killed 500-plus penguins? How scientists solved the mystery

Researchers investigating a mass die-off of over 500 Adélie penguins on Antarctica's Danger Islands have ruled out avian flu as the primary cause. Dr. Ralph Vanstreels and his team discovered thousands of carcasses across the mega-colonies during their March 2024 expedition. While the investigation into the exact cause of death continues, the findings challenge initial assumptions about the role of the virus in this specific ecological tragedy, as reported by NPR.
