Researchers in Toronto are using tiny backpacks containing geolocator sensors to track songbirds on migration. Bridget Stutchbury, a biology professor at York University, said the research has revealed that scientists have underestimated how quickly the birds can travel. Stutchbury and her team placed miniaturized geolocators on 14 wood thrushes and 20 purple martins in 2007, tracking their journey from Pennsylvania to South America and back. They found the songbirds can fly more than 311...
