Population justification: The population size is suspected to fall in the range 50,000-499,999 mature individuals (Partners in Flight 2020). The species can be locally common in parts of its range, but is generally only infrequently observed (Carroll et al. 2020).

Trend justification: The population is undergoing a large, significant decline owing to ongoing habitat destruction and unsustainable levels of hunting (del Hoyo et al. 1994, Carroll et al. 2020, Partners in Flight 2020). Locally, the species may also suffer from predation by dogs and cats (D. F. Cisneros-Heredia in litt. 2022), but the impacts on the population size are unclear.
Over the last three generations (12.3 years; Bird et al. 2020), approximately 9% of tree cover has been lost within the range (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). This species is restricted to the floor and lower strata of lowland forest (Carroll et al. 2020); therefore it is conceivable that population declines are faster than the rate of forest loss alone, as forest degradation may increase the rate of decline by an additional 5%. Even though the impact of hunting has not been quantified, it is tentatively assumed that this threat increases the rate of population decline by a further 5%, so that overall the rate of decline over the past three generations would amount to 19%. To account for uncertainty, the rate of past decline is here placed in the band 1-19% over three generations.
Since 2016 tree cover loss has been accelerating to a rate equivalent to 12% over three generations. Accounting for the additional impacts of forest degradation and hunting, it is assumed that the rate of population decline exceeds the rate of forest loss by 10%, so that the population decline over the next three generations would amount to 22%. To account for uncertainty, the rate of decline projected forward from 2016 is here paced in the band 20-29% over three generations. These values however require confirmation.
