RIP to a great one, Dr. Roger Payne, who helped discover singing as a form of communication among whales. I had the opportunity to interview him at length early on in the pandemic for a long-form writing project I'm still in the midst of. He was sharp, funny, and generous. He leaves behind an incredible legacy of acoustic ecology. We have a richer sense of life on our planet because of his life's work.
