Birds are indicators of the environment. If they are in trouble, we know we'll soon be in trouble.

Butterflies may be better indicators of the health of our environment than birds.

Birds have wings; they're free; they can fly where they want when they want. They have the kind of mobility many people envy.

The more you look, the more you will see.

Conservation is not just an ideal that we read about; it works.

Not all is doom and gloom. We are beginning to understand the natural world and are gaining a reverence for life - all life.

Vultures are homely, but they clean up all the garbage and that's good. And they're elegant in the sky.
