Population justification: The population size is preliminarily estimated to fall into the band 2,500-9,999 individuals. This equates to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.

Trend justification: Although it disappeared from Manus for unknown reasons during the last century, this species is not thought to be declining.
