Prime Video revealed the official trailer for Wild Isles, the nature documentary series narrated by Sir David Attenborough, premiering April 21, in time for Earth Day.

The five-part natural history series centers on the British Isles, which is one of the most diverse and beautiful landscapes on Earth, and the series is full of behaviors never before seen on screen. The breathtaking aerial photography reveals the beauty of the British countryside, and motion controlled time-lapse photography brings to life the story of the passing seasons. The latest low-light cameras uncover the secret nocturnal lives of many of our favorite animals, and macro photography reveals the miniature worlds of rock pools, ponds, and grasslands. The series was captured over three years in 4K resolution.

“In my long lifetime, I have traveled to almost every corner of our planet,” said narrator Sir David Attenborough. “I can assure you that in the British Isles, as well as astonishing scenery, there are extraordinary animal dramas and wildlife spectacles to match anything I have seen on my global travels.”
