{A thread 🧵...} @SciReports Bruce was found in the wild as a juvenile, missing the top half of his beak. No one is quite sure how this happened; one possibility is that it involved an accident with a pest trap. He was brought into the South Island Wildlife Hospital where he was nursed back to health. {1/14}
