Grizzly Bear Cubs And Me, BBC2, 9pm

Part one of two. Gordon Buchanan joins the Pazhetnovs, a pioneering family of biologists in Russia as they attempt to rehab grizzly bear cub orphans. There are more than 100,000 grizzlies in Russia and as humans encroach further into this vast wilderness, conflict is increasing. The Pazhetnovs have been rescuing orphaned cubs for nearly three decades. Gordon arrives in February when six cubs have just been rescued. They are just five weeks old and each weighs less than a bag of sugar.
