Zavodovski Island loses title of world's largest penguin colony
The British Antarctic Survey reported that Zavodovski Island has lost more than 500,000 chinstrap penguins since 2011. Warming waters are reducing access to krill, the researchers said.
Why it matters
The collapse signals how ocean warming is disrupting the Antarctic food web.
Background
Chinstrap penguins feed mainly on Antarctic krill. Zavodovski, a volcanic island in the South Sandwich chain, long hosted the largest known penguin colony.
