Population justification: Unpublished data from the Fiji IBA project (G. Dutson in litt. 2005) suggest that the global population numbers 1,000-10,000 individuals, roughly equivalent to 670-6,700 mature individuals. |
|
Trend justification: There are insufficient data available to formally estimate the species's population trend, but it is suspected to be undergoing a slow to moderate decline owing to predation by introduced mammals. |
