On Earth Day, theSecrets of the Penguinswill be revealed.

WhileSecrets of the Penguins’premiere date is still over a month away, PEOPLE has an exclusive first look at the show’s trailer right now.

The trailer opens withBertie Gregory,the filmmaker and Nat Geo explorer who leads the new show, kneeling amongst a group of emperor penguins.

The clip continues with dynamic shots of the numerous penguin species featured in the series, including Gentoo and rockhopper penguins, while Lively recites the birds' achievements.

“They teach. They toil. They practice parenting and act really brave for their size,” Lively lists throughout the video.

The trailer continues with more stunning snippets showing how penguins manage to face predators, attempt daring dives, and coexist with humans. It closes with Lively promising that viewers of the new series will learn the truth about penguins in “black and white.”

To collect the secrets shared inSecrets of the Penguins, Gregory and a team of over 70 crew and scientists went on a two-year, globe-spanning journey to meet the birds on their turf. The trip took the team to the rocky beaches of Cape Town, the shores of South Georgia Island, the tropical Galapagos Islands, Namibia’s desert caves, and Ekström Ice Shelf in Antarctica — where a three-person film crew spent 274 days filming a colony of 20,000 emperor penguins.

This dedication to the project led to some firsts in wildlife documentation. Viewers ofSecrets of the Penguinscan expect to see the first footage of emperor penguin parents practicing their egg-handling skills with snowballs and of healthy “rockaroni” chicks—rare hybrids of rockhopper and macaroni penguins.
