The Perpetual Notion Machine speaks with Nick Bayly, Chief of Migration Biology at SELVA in Bogota, Columbia. He is studying bird migration through the Neotropical Region of Central and South America to understand the needs of long-distance migratory birds that breed in Wisconsin and other area of North America, and migrate south during the winter. The Neotropical Flyways Project receives funding from the Natural Resources Foundation of Wisconsin’s Bird Protection Fund.
