00:00Almost two-thirds of chinstrap penguins have vanished from the world's largest colony on Zawodowsky Island.
00:05New research from the British Antarctic Survey reveals a 63% drop in occupied nests since 2011.
00:13This steep decline is linked to climate change shifting the penguins' food supply,
00:17especially krill moving southwards with warming waters.
00:20The chinstraps cannot follow because of sea ice and a lack of nesting sites farther south.
00:25Meanwhile, macaroni penguins on the same island are thriving thanks to a more varied diet.
00:31The study calls this the biggest change in community composition ever observed at a single location in Antarctica.
00:38According to lead researcher Professor Norman Ratcliffe,
00:41the penguins' decline shows how rapid warming is reshaping sensitive Antarctic ecosystems.
00:46The title of the largest penguin colony has now moved over 5,000 kilometers away to Cape Adair in the
00:53Ross Sea.
