When was the last time you stopped and really listened to birdsong? Ever wonder what they’re singing about? We chat to Kenn Kaufman and Dr. Irene Pepperberg about the extraordinary complexity to the avian arias, how they’re produced, what they mean, and how vocal acrobatics can reveal a surprising hidden intelligence. 

Twenty Thousand Hertz is produced out of the studios of Defacto Sound, and hosted by Dallas Taylor.
