Population justification: The global population size has not been quantified, but the species is described as evidently rather rare (del Hoyo et al. 2007).

Trend justification: The population is inferred to be in decline owing to on-going habitat clearance, mainly for shifting agriculture (del Hoyo et al. 2007).
Between 2000 and 2019, this species's range experienced a 8.6% loss in forest cover (Global Forest Watch 2020). This equates to a loss of 5% over three generations. Assuming the population declines at a similar rate, the rate of decline is placed in the band 1-10%. Between 2016 and 2019, this species's range experienced forest cover loss of 3.4% (Global Forest Watch 2020). Projected forward over three generations this equates to a loss of 9%. Assuming that the population declines at a similar rate to forest loss, the future rate of decline is suspected to fall in the band of 10-15%.
