Population justification: This species has not been recorded since 1939. Surveys carried out since 1949 have been unsuccessful in recording any individuals, though unconfirmed reports from local people exist. Any remaining population is likely to be tiny.
Trend justification: Trends are unknown, but any remaining population, if it exists, is likely to be declining owing to human disturbance and conversion of habitat to aquaculture and agricultural land, and perhaps hunting.
