The 97-year-old broadcaster has already started filming his introductory scenes for the new wildlife series - which is due to air on BBC One later this year after being commissioned in 2019 - having presented the original 'Planet Earth' in 2006 and its follow-up a decade later.

Executive producer Mike Gunton told the Daily Mirror newspaper: "'Planet Earth' wouldn’t be 'Planet Earth' without David, so I’m delighted he is presenting the third series.

"As ever, he has brought his huge enthusiasm and wisdom, has been encouraging about our new perspective and has, I know, really enjoyed seeing the extraordinary new wonders brought to the screen."

Sir David shot his first opening as "the sun shone under blue skies" in what was a very significant and approrpriate spot.

Mike added: "The opening of the series with David was filmed in the beautiful British countryside in exactly the location where Charles Darwin used to walk whilst thinking over his Earth-shaking ideas about evolution.

"It seemed the perfect place for David to introduce 'Planet Earth III' and remind us of both the wonders and the fragility of our planet.”

The eight-part programme promises to showcase amazing animal footage from around the world, as well as some that has never been aired before.

Creatues set to be highlighted include tropical Mobula rays, the Canadian spirit bear and African Jacana birds.

The show is looking to shine a light on the way animals have developed certain strategies through evolution, as well as the challenges they must face in the modern world.

Meanwhile, the final episode of the series will celebrate human "heroes" dedicating their lives to save certain species.
