A new BBC film, Snow Wolf Family and Me, explores the lives and habits of arctic wolves, revealing the family secrets of one of our most feared predators.
Ellesmere Island is one of the most remote and beautiful places on Earth. This is the only place in the world where wolves are naive to man and have no fear. It allowed wildlife cameraman Gordon Buchanan and scientists an unparalleled opportunity to form bonds with a wild wolf family, revealing the remarkable story of their relationships and behaviour.
Here series producer Ted Oakes talks about some of the highlights and challenges of being accepted by a wild wolf pack.
Snow Wolf Family and Me will be broadcast on 29th and 30th December 2014 at 21:00 on BBC Two.
