EAST LANSING, Mich. (AP) — Scientists and students placed tracking bands on four boisterous peregrine falcon chicks who live on top of Michigan State University’s football stadium. The birds are named Pickles, Muhammad, Egbert and Swooper. They weren’t too happy about the experience, writhing and squawking during the banding process. Moments earlier, a Michigan wildlife biologist and a representative of the university’s Department of Fisheries and Wildlife journeyed to the roof to retrieve the chicks. That was despite their parents angrily screeching and swooping above. Now that the chicks are tagged, researchers will be able to keep tabs on the birds’ migration patterns.
