The BBC have released a collection of clips of David Tennant narrating Growing Up Wild - Natural World.

About the episode:
A look at the challenges young animals face, from their first steps through to leaving home.
For any animal, the early days of life are often the most difficult. Finding food, avoiding predators and generally learning life's essential skills is tough. However, with a little parental guidance growing up can be an adventure.
By following some special tiger cubs in India, an adolescent mountain gorilla in Uganda and two nervous polar bear cubs in the high Arctic, the trials and tribulations of growing up wild are revealed.

BBC Two's classic wildlife series, the Natural World, tells in-depth stories of incredible animals, featuring award-winning photography in some of the most extraordinary places in the world. Produced by the BBC Natural History Unit in Bristol, it is now in its 34th season.
