Population justification: The population has not been quantified but was estimated to be in the thousands assuming an average of 1 pair/km along a mostly linear distribution of c.6,000 km (Ferguson-Lees and Christie 2001).

Trend justification:

This species is precautionarily suspected to be undergoing moderately rapid ongoing declines owing to loss of its mangrove habitat.
