In Volcanic Islands Create a Penguin Sanctuary, narrator Sir David Attenborough tells the fascinating survival story of chinstrap penguins living on Zavodovski Island. This island, located in the Southern Ocean, is home to the world’s largest chinstrap penguin colony, despite its treacherous seas and an active volcano. The penguins have adapted to extreme conditions, using the island’s isolation and volcanic landscape as a refuge from predators. This video is excerpted from BBC’s Planet Earth II, a breathtaking documentary series that highlights the natural wonders of our planet.
