|---|---|---|---|---|
| No. of mature individuals | 600-1700 | poor | Suspected | 1982 |

| Population justification: The species occurs throughout the Palau archipelago but it is rare on most islands. It is common only on the small Rock Islands where in 1982 there were thought to be 500 individuals. The population is therefore likely to be at the lower end of the band 1,000-2,499 individuals. This equates to 667-1,666 mature individuals, rounded here to 600-1,700 mature individuals. | ||||
| Trend justification: There are no data on trends. However, the species is relatively secure on some tiny islands and is suspected to be stable overall. | ||||
