What I am interested in with birds, just as I am with spiders or monkeys, is what they do and why they do it.

I think the most alarming animals I have encountered are really poisonous snakes.

I've been bitten by a python. Not a very big one. I was being silly, saying: 'Oh, it's not poisonous' Then, wallop! But you have fear around animals.

All life is related. And it enables us to construct with confidence the complex tree that represents the history of life

I'm swanning round the world looking at the most fabulously interesting things. Such good fortune.

I suffer much less than many of my colleagues. I am perfectly able to go to Australia and film within three hours of arrival.

The process of making natural history films is to try to prevent the animal knowing you are there, so you get glimpses of a non-human world, and that is a transporting thing.
