Once hunted to local extinction, puffins have made a dramatic comeback and been re-established to historic nesting islands in Maine. This project combines a scientific adventure story about puffin restoration with data investigation on the relationships between puffin health and environmental factors. Students examine trends in several decades of curated National Audubon Society data about puffins, using an accessible open-source data tool to examine relationships among variables such as sea surface temperature and puffin weight. They also use data from puffin webcams and train an AI system to identify puffins. We are researching how to make these tools accessible to English language learners and how the technology enhances student engagement and understanding of what ecologists do. Students also learn about the careers of people from diverse backgrounds who have worked on Maine's puffin islands to learn how data are being used to study ornithology and climate change.
