If you've never stopped by the side of the trail to listen to a beetle larvae chewing on a pine tree, or to the sound of the woodpecker looking for that beetle, we'll give you a chance in this podcast episode. If you've never been puzzled by the high-pitched voice of a male elk bugle, we encourage you to take the time to wonder about nature's oddities. Focusing on underappreciated sounds and sensations opens up an enormous world of insight and beauty. Guest: David George Haskell, author of "Sounds Wild and Broken: Sonic Marvels, Evolution's Creativity, and the Crisis of Sensory Extinction" and Professor of Biology at Sewanee: The University of the South
