Birds are the most popular group in the animal kingdom. We feed them and tame them and think we know them. And yet they inhabit a world which is really rather mysterious.

The nature of human beings is that they'd far rather face the disaster that is happening tonight than the one that is happening tomorrow.

Everyone likes birds. What wild creature is more accessible to our eyes and ears, as close to us and everyone in the world, as universal as a bird?

What humans do over the next 50 years will determine the fate of all life on the planet.

I'd like to see the giant squid. Nobody has ever seen one. I could tell you people who have spent thousands and thousands of pounds trying to see giant squid. I mean, we know they exist because we have seen dead ones. But I have never seen a living one. Nor has anybody else.

If I can make programmes when I'm 95, that would be fine. But I would think I'll have had enough by then.

I remember when we were in the World Cup in Australia and I had to win the singles against Tony Payne, best of seven legs, to win it. I was 2-0 down but ended up beating him I suffer much less than many of my colleagues. I am perfectly able to go to Australia and film within three hours of arrival.
