From cliff-diving to months-long hunger spells, emperor penguins keep proving they’re the ultimate survivalists in one of Earth’s harshest environments. National Geographic and BAFTA-winning cinematographer Bertie Gregory have now captured something never seen before: emperor penguin chicks hurling themselves 50 feet off an Antarctic cliff. This remarkable moment appears in the 2025 edition of National Geographic’s Emmy-winning SECRETS OF series, SECRETS OF THE PENGUINS, offering a thrilling new glimpse into penguin life at the edge of the world.
