Late in 2013, snowy owls started showing up in places no one expected to find them-including Florida. What had caused so many of these majestic birds to leave their Arctic home and fly to southern Canada and the United States? Scientists quickly began working to find out. Author Sandra Markle brings together firsthand reports from the scientists involved along with stunning photographs of the owls to explain this rare event, known as an irruption. Follow along as scientists figure out why snowy owls took part in this unusual migration and discover what they learned from the unexpected opportunity to study them up close.
