Caption: With hopes of recapturing the bird next year, biology professor Bridget Stutchbury of York University, Toronto, releases a purple martin outfitted with a tiny geolocator for its round-trip migration. Two purple martins -- as well as five wood thrushes -- returned to their starting place in Pennsylvania, allowing scientists to reconstruct their routes. The research was partly funded by National Geographic.
