Chlidonias 22 Nov 2025 The government checklist has C. spaldingi on the island instead of C. robustus (Wildlife of Magnetic Island National Park (Department of the Environment, Tourism, Science and Innovation)) - it seems both might occur there / both might be the same species. Apparently C. robustus has four supraorbital scales while C. spaldingi has three, which would make this one C. robustus.
