Matt Rayner (Tāmaki Paenga Hira Auckland Museum, New Zealand) and colleagues write in the journal Notornis on Northern Buller’s Albatrosses Thalassarche bulleri platei in the Manawatāwhi/Three Kings Islands.  Six occupied nests were found on Rosemary Rock, with four unguarded live and two dead chicks present.  “Compared with previous observations our count suggests a poor breeding season for Buller’s mollymawk on Rosemary Rock in 2019/20.  [F]urther work is clearly required to ascertain the trajectory and threats to New Zealand’s most northern albatross colony.”
