Merry Christmas, and an idea for that gift you forgot

I received a set of DVDs containing the BBC series Living Planet. Even viewers like myself who think they know something of natural history will gape at images of otters driving off a crocodile, cranes battling team-hunting golden eagles as they try to surmount the Himalayas, and macaques swimming underwater just for the fun of it. And that's just part of Disc 1. Diary segments about the challenges and techniques of filming this series are just as fascinating as the documentary itself.
