Students Band Birds 6

Students Band Birds 6

By blowing gently on the underside of the bird - in this case, a common yellowthroat - banding volunteers can check skin color. Yellowish areas indicate that the bird is carrying fat, which suggests it's a migratory bird rather than a year-round resident. Emily Thomas, a Penn State master's student in wildlife and fisheries science and a licensed bander, has been teaching other students how to band birds during the current migration season.
