Thousands of baby penguins they bravely fell off a huge 15-meter cliff and swam for the first time in the icy waters of Antarctica.

Incredible new footage shows the penguins diving one by one, making for an incredible sight.

Look at the amazing National Geographic video:

National Geographic’s award-winning director of photography, Bertie Gregory, spent a freezing two months tracking the flock of 10,000 emperor penguins on the Antarctic Peninsula. He succeeded and captured the behavior of the chicks who had never seen a camera before, as he told “Good Morning America”.

“It’s called jumping, when they take their first bath,” he explained, adding: “Normally they jump off the sea ice, which is 1 or 2 feet high. We were noticing that these trains of chicks were going through a different place. So I launched the drone, flew it over there to see what was going on and realized they were piling up on the edge of a huge 50-foot (15-meter) ice cliff,” he continued.
