Population justification: The population is estimated to number 2,000-3,000 indiviauls, based on Watling (1988) and Anderson et al. (2012). This equates to 1,333-2,000 mature individuals, rounded here to 1,300-2,000 mature individuals.
Trend justification: The species is tolerant of habitat degradation and does not appear to be declining despite the presence of introduced predators. Based on results from Anderson et al.'s (2012) survey, there appears to be no evidence for a population decline. Consequently, its population is suspected to be stable.
