Population justification: The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. 1996). This population is suspected to be in decline owing to ongoing habitat degradation and possibly predation by introduced mammals (del Hoyo et al. 2004).

Trend justification: This population is suspected to be in decline owing to ongoing habitat degradation and possibly predation by introduced mammals (del Hoyo et al. 2004).
