"I thought I would like to show that these kids can do something which is in fact very skillful - not the old tale about them being cobblers and joiners, but something that means they have to get books out of the library. And it’s a technical skill; they’ve actually got to read about it before they can do something like training a hawk. My brother trained a kestrel in these fields at the back, and I wanted to show that kids can do this kind of thing. They can do all kinds of things if only they’re given opportunities."
