Population justification: The global population size has not been quantified, but the species is described as often common in suitable habitat (del Hoyo et al. 2007).

Trend justification: This species has declined or disappeared from a number of historical sites, and is suspected to be declining at a moderately rapid rate throughout much of its range as a result of on-going forest clearance.
