Population justification: The global population size has not been quantified, but the species is described as uncommon to locally fairly common (del Hoyo et al. 2007).

Trend justification: The species is considered to be declining due to logging and the conversion of forest to coffee plantations. A remote sensing study found that forest cover was lost at a rate of 4% over three generations (13.8 years) within the range (Tracewski et al. 2016). Assuming that population declines are proportional to forest loss and that declines are ongoing at a similar rate into the future, the species is thought to decline by < 10% over three generations.
