Justification of Red List category
This species has not been recorded since 1953 despite recent surveys lasting several weeks, and hunters no longer report the species in areas close to the type locality from where it was known to hunters in 1974. It is likely to have declined as a result of depredation by introduced mammalian predators. However, it cannot be presumed to have gone Extinct because there have been recent credible reports, and further surveys are needed in the Wainoni hills and in the swamps of north Makira. Any remaining population is likely to be tiny, and for these reasons it is treated as Critically Endangered.
1-49 mature individuals
Distribution size (breeding/resident):
Land-mass type - oceanic island - Oceanic islands are islands or island groups that are <200,000 sq km in size and separated from other land masses by >200 m sea depth. Generally Oceanic islands are islands or island groups that are <200,000 sq km in size and separated from other land masses by >200 m sea depth. Generally they have never been connected to a continental area by a land-ridge, and are volcanic in origin.
