A new study released Thursday by a team of international researchers is shedding light on where the iconic birds travel in winter, and how their destination may affect their ultimate survival. The data tracked how far the puffins travelled, calculated the energy they expended and determined whether they mixed with other colonies. “The big surprise out of this study was relating the breeding success of colonies to their migration,” he said of the paper, published in Current Biology. “Those wintering closest to the breeding colony do better. But he said knowledge of their wintering habits is key, since it is when the species experiences the highest mortality.
