Population justification: The global population size has not been quantified, but the species is reported to be erratic and occasionally locally quite common (Flegg and Madge 1995).

Trend justification: This population is suspected to be in decline owing to habitat loss and degradation, fire, and introduced predators (del Hoyo et al. 2007).
