You get a very different insight into the natural world when you have the opportunity to study the behaviour of individual animals.

Sir David Attenborough recalls with sumptuous delight spotting a blackbird in his garden with a white feather - "whitey" - giving him a window into the life of blackbirds and what's more, that individual. And, he says, he saw what blackbirds get up to!

David remembers filming spiders and filming chimpanzees, both of which benefited from someone knowing about the individuals - and whether you're a spider or a chimpanzee, you have a personality all of your own.
