Birds Are An Ecological Litmus Paper.

The Other Creatures With Which We Share This World Have Their Rights Too, But Not Speaking Our Language, They Have No Voice, No Vote; It Is Our Moral Duty To Take Care Of Them.

The Philosophy That I Have Worked Under Most Of My Life Is That The Serious Study Of Natural History Is An Activity Which Has Far-reaching Effects In Every Aspect Of A Person's Life. It Ultimately Makes People Protective Of The Environment In A Very Committed Way. It Is My Opinion That The Study Of Natural History Should Be The Primary Avenue For Creating Environmentalists.

Butterflies May Be Better Indicators Of The Health Of Our Environment Than Birds.

Conservation Is Not Just An Ideal That We Read About; It Works.

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.
