Smithsonian researcher Roxie Laybourne may be the most influential ornithologist you've never heard of. Over the more than half a century she was a pioneering figure in the fields of forensics and aviation, all through her work with birds, and, more specifically, their feathers. Her incredible life is documented by journalist Chris Sweeney in the book, The Feather Detective: Mystery, Mayhem, and the Magnificent Life of Roxie Laybourne, released earlier this year. Chris joins us to talk about Laybourne's legacy in fields that go far beyond birds.
