Population justification: The population is estimated to number 1,000-2,499 individuals, equating to 667-1,666 mature individuals, rounded here to 600-1,700 mature individuals. This estimate was derived by BirdLife International (2000) from the observation that the species may be fairly common in the c.150 km2 of available marshland habitat.
Trend justification: A moderate and ongoing population decline is suspected to be occurring on the basis of the declining quality of habitat within small total range.
