This week, we’re looking at birds, and what the study of their behavior and anatomy can tell us about ourselves. We’ll talk to Dr. John Marzluff, professor of Avian social ecology and demography at the University of Washington, about his book Gifts of the Crow: How Perception, Emotion, and Thought Allow Smart Birds to Behave Like Humans. And we’ll speak to artist and illustrator Katrina van Grouw about The Unfeathered Bird, her book that looks at bird anatomy below the feathery surface.
