Section 66 pair, guarding their hollow. Of note - pink cheek feather on left-hand side. First noticed in photos taken at 66 during 2021 nesting season. A possible identifier? (I believe this is a different female to the rose-feathered female gang gang, because the feather is located on a different position on the face, and their beaks are a different shape and colour. However, I wonder if they are related - perhaps the feather and genetics study will be helpful here?)
