Earth Day! We talk with Kathleen Rogers, president of the Earth Day Network, and discover nature quotes from Thomas Edison and Groucho Marx. And we meet a bird that loves Golden Retrievers.
We hear the strange legend of a bird hatched from barnacles. Also: what's happening to our honeybees. And Mike O'Connor answers a most unusual question.
More controversy about the Ivory-Billed Woodpecker; amazing news about what Hummingbirds can remember; and our Mystery Bird Contest links the East Coast with the West Coast.
