Population justification: The global population size has not been quantified, but the species is described as generally scarce to rare, although locally commoner on smaller islets (Gibbs et al. 2001).

Trend justification: The species is assumed to be declining at a moderately rapid rate, owing to habitat destruction, trapping for food and the pet trade as well as the effects of introduced predators.
