Justification of Red List category
Endemic to the island of Maui, Hawaii, this species was first discovered in 1973. However, it declined rapidly between 1975 and 1985, predominantly due to invasive species and disease. By mid-1997 only three individuals remained. One was captured in 2004, but it died later that year. The other two individuals have not been reported since 2003 and 2004, with no others reported despite intensive surveys. A set of papers published in 2017 (Akcakaya et al. 2017, Keith et al. 2017, Thompson et al. 2017) laid out methods for quantitatively estimating a species’s probability of extinction based on parameters associated with threats, in addition to records and surveys. Based on the application of these methods (Butchart et al. 2018), this species is regarded as extinct.
