Birds ... are sensitive indicators of the environment, a sort of "ecological litmus paper," ... The observation and recording of bird populations over time lead inevitably to environmental awareness and can signal impending changes.

Birds, it must be admitted, are the most exciting and most deserving of the vertebrates; they are perhaps the best entre into the study of natural history, and a very good wedge into conservation awareness.

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

Birds are, perhaps, the most eloquent expression of reality.

The truth of the matter is, the birds could very well live without us, but many -- perhaps all -- of us would find life incomplete, indeed almost intolerable without the birds.

We don't have to go to wild places to find wildlife. A surprisingly wide range of species can be found in our sities and towns, from familiar animals like the raccoon to more exotic ones like the mountain lion.

Butterflies are very interesting. Here these things are little grubs for a while. And then they go into a little coffin. There they are in a sarcophagus, and then they come out and dance with the angels.
