We're all born listeners. And as a result of our modern lives, and living in a world that has less meaning than the natural world that we evolved to hear, we learn to think of listening not as taking in all the information with equal value, which is the definition of true listening. In our modern world, we tend to think of listening as focusing our attention on what is important and filtering out everything else.

I work in the same style as classic landscape photographers. You find the right perspective, and then you wait until the light is right. I do the same. I find the right location, and then I wait for the sound, the atmosphere to be right, and for the space to be revealed.

I used to hate the urban environment and the urban din. But I realize now that it's really not that much different than living next to a waterfall for wildlife. Most wildlife - unless they're specifically adapted - avoid being around a waterfall or whitewater streams and rivers because it jams their sense of surveillance. They are more vulnerable, and their message loses intelligibility. Now, the ouzel is able to overcome that in various ways. Back to the urban environment, we're talking and delivering messages as if we weren't next to a waterfall, and that's a problem.

When you listen to nature, it may still be difficult to live a life, but it's inspiring.

The normal way of gathering information is through sound: when you hear information that you want to gather, you look in its direction, you see what it is, if you choose you can get closer, you can see it, you can touch, and then, finally, the most committed form of data gathering is to taste it and eat it. But for the urbanite, we're cut off from our primary sense, and I want to stress that - our primary sense of gathering information about the place that we're living in - and instead, we're in a war zone.

Often how you define the problem will determine whether or not you're able to find a real solution.

Most people think visual information is more important than aural information - like, what's this big deal about sound? And why should I bother to listen, rather than look? And here are the facts: there are blind species, in the backs of the caves, the bottoms of the oceans. It's not essential on planet Earth to be able to see, to be a species. But there are no deaf animal species. You have to be able to hear, or you won't get the information you need in order to survive.
