The Singing Life of Birds (REBROADCAST)

What do birds sing, why and what does it mean? We'll explore those questions with author and scientist Donald Kroodsma. His new book "The Singing Life of Birds" explains how birds acquire their songs, what makes them unique, and how they evolve. We will also take a listen to actual recordings of some familiar and not so familiar bird songs throughout the show.
