Population justification: The population is estimated to number at least 1,700 individuals in total, roughly equivalent to 1,400 mature individuals (Robertson in litt. 2016).

Trend justification: The species is now confined to a few offshore predator free islets where the population is stable, and one predator free location on the mainland.
