The world's largest chinstrap penguin colony has declined by two-thirds since 2011, likely due to climate change.

The world's largest chinstrap penguin colony on Zavodovski Island, the northernmost of the South Sandwich Islands in Antarctica, has undergone a dramatic decline. The population has fallen by two-thirds since 2011, according to a new study.

Climate change is blamed for the rapid demise of the penguins. Scientists have warned that the collapse increases the risk of a wider ecosystem collapse in the region.
