Monarch 'death data' could help save endangered butterflies

Using eyelash glue, Eddie, an endangered monarch butterfly was fitted with a toothpick-sized radio-tracker before being set free by Laura Burns, a Conservation Programs Manager at the Assiniboine Park Zoo. She tracked Eddie’s journey, as well as 28 other butterflies in the hopes that the data they gather will help researchers understand how climate change is taking a toll on the endangered species.
