Population justification: The population size is estimated not to be above a few hundred by BirdLife International (2000), based on analyses of recent records and surveys. It is placed in the band 250-999 mature individuals here, equating to 375-1,499 individuals in total, rounded here to 350-1,500 individuals.

Trend justification: There are no data; however, there is little reason to suspect a decline.
