Justification of Red List category
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 0.984, and the probability it is extinct based on threats is 0.941. Accordingly, it is classified as Extinct. This species has not been recorded with certainty on Kaua'i since 1989 nor on Hawai'i since 1987, and recent searches specifically for it, alongside extensive surveys for other species on both Kaua'i and Hawai'i, have failed to locate it. It was driven to extinction by habitat loss and degradation, introduced rats, cats, pigs and other non-natives, and in particular as a result of avian malaria and avian pox viruses from introduced mosquitoes.
