Scientists Investigate What Killed More Than 500 Penguins in Antarctica
Researchers looked into a mass die-off of penguins on Antarctica's Danger Islands, with avian flu as the prime suspect. What they found surprised them, but the short source text does not name the cause.
Researchers have worked to establish why more than 500 penguins died on the Danger Islands in Antarctica. Avian flu, a viral disease that affects wild and domestic birds, was the main suspect at the outset.
The findings of the investigation surprised the scientists, because what they found did not match that initial suspicion. The result matters because identifying the exact cause helps show whether wild bird colonies in Antarctica face avian flu or a different pathogen.
The available source excerpt does not say what exactly killed the penguins, when the deaths occurred or which penguin species were affected, so those details are not given here. A fuller account of the research is in the material published by NPR.
