Population justification: The population size of this species has not been quantified, but it is described as generally scarce to locally common.

Trend justification: Data on precise rates of decline are lacking, but continuing patterns of loss and degradation of mangrove habitats suggest that a moderately rapid decline is likely to be occurring throughout the species's range.
