In 2000, an adult pair of non-migratory Grus americana (Whooping Crane) left Florida and settled in Michigan for the summer. On 21 November, the pair left Michigan and was radio-tracked south to the north shore of Lake Erie. The next day, only the female was detected. She was tracked to Kissimmee Prairie, FL, her release site as a subadult. This female flew from Michigan to Florida in 11 days, only stopping for 2 of those days. Her movement and flight behavior approximated natural Whooping Crane migration behavior. That this adult female could return to her release area and physiologically prepare for a long flight suggests migration is both learned and innate. Our conclusions help refine reintroduction techniques possible for migratory cranes.
