Birds Are An Ecological Litmus Paper.

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.

Birds Are Indicators Of The Environment. If They Are In Trouble, We Know We'll Soon Be In Trouble.

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.

More Birds Have Adapted To A Changing World Than Have Failed. Very Few Have The Narrow Tolerance Of The Ivory-billed Woodpecker Or The Bachman's Warbler.
