"The ripples from a single conservation effort can spread all over the world," says writer and researcher Scott Weidensaul in his latest book, "The Return of the Oystercatcher: Saving Birds to Save the Planet." Scott Weidensaul: The book is about what's working for bird conservation, bird conservation success stories. But, as seen, birds are more resilient than we give them credit for. If you have windows that birds fly into, that's like another billion birds a year that die at window strikes. Dave Anderson: And I'd add one more, which is to bring youth out to watch birds and learn about birds.
