Population justification: The global population size has not been quantified, but the species is described as fairly common on Palau, Yap Pohnpei and Kosrae and rare to extinct on Chuuk and some of the Marshall islands (Gibbs et al. 2001).
Trend justification: There are few data on which to calculate a trend; however, the species is hunted through much of its range and habitat loss, which has been dramatic in certain places, is suspected to be causing a slow to moderate population decline. Recent surveys suggest the species may be declining rapidly on some islands, and further analysis of survey data is required to confirm this.
