The Bear Whisperer: When cameraman Gavin Thurston goes in search of grizzly bears in Alaska, he entrusts his life to an unusual guide - Buck Wilde, a man who talks to bears.
In place of guns or "bear spray", behavioural expert Wilde uses nothing more than his voice and a black bin bag for protection. But will Wilde's methods allay the fears of Thurston, for whom this is a first encounter with bears?

6.10 Natural World The Canine Conspiracy. This film explores new evidence suggesting that, rather than being "man's best friend", dogs are the world's most convincing and successful social parasites, able to manipulate domestic situations to meet their own needs. Have they exploited human's for thousands of years, and, if so, how could this have happened, and why is such a spectacular and successful invasion tolerated ? Narrated by Richard Briers.
