Justification of Red List category
This species was endemic to Norfolk Island, Australia, however it rapidly declined primarily due to predation by black rats. Four records during an island-wide survey in 1979 were the last multi-observer records, with poorly documented reports suggesting the species possibly persisted until the first decade of the 21st century. Following methods developed in a series of papers published in 2017 (Akcakaya et al. 2017, Keith et al. 2017, Thompson et al. 2017), the probability that the species is extinct based on records and surveys is 0.99, and the probability it is extinct based on threats is 0.98. Accordingly, it is classified as Extinct.
