Chinstrap Penguins Sleep 10,000 Times a Day — Here's Why ｜ Antarctica 4K Documentary

A nesting chinstrap penguin falls asleep more than 10,000 times a day, four seconds at a time. Here is why, and why the species' biggest colonies are shrinking.

Why would a penguin sleep like that? Because a skua can take an unguarded egg in a moment. Follow the scientists who wired 14 nesting chinstraps on King George Island, the 4-second naps that add up to 11 hours, the leopard seal at the water's edge, and the counts on Elephant Island, Deception Island and Zavodovski that show colonies in decline. Two stories, one bird: a sleep strategy that works in seconds, and an ocean that is changing over decades.

Every number in this film comes from a named source: Science, Science News, Smithsonian, The Guardian, NPR, Scientific Reports, Polar Biology, Nature Climate Change, Current Biology, the British Antarctic Survey, CNN, National Geographic and the Australian Antarctic Program. Where accounts differ, the narration says so. No footage of the study colony, Elephant Island's counts or Zavodovski exists in our library: those passages are illustrated with real chinstrap and Antarctic footage from other places, and the narration says so.

Nuvora Antarctica presents an original nature documentary made with real Storyblocks footage and American English narration.
