Over two extraordinary years, National Geographic Explorer Bertie Gregory discovers secret traditions, surprising intelligence and close-knit societies of gregarious penguins, never filmed before. This astonishing series reveals they are more like us than we ever dared dream, from courageous risk-takers to the power of friendship, and adventurers using ingenuity and innovation in some of the world’s most extreme places.
