Population justification: The global population size has not been quantified, but the species is described as common (del Hoyo et al. 2006).

Trend justification: This species is suspected to be declining in line with ongoing habitat loss. Data from Global Forest Watch (2021) suggests that the rate of decline is likely to be <20% over 10 years.
