Population justification: The population size has not been estimated following recent taxonomic splits, but the species occurs at low densities (G. Dutson in litt. 2012) and the overall population is presumed to be moderately small.

Trend justification: The population is suspected to be declining locally owing to ongoing habitat destruction (del Hoyo et al. 2001).
