Population justification: The global population size has not been quantified directly, but this species is described as fairly common to locally common (Stotz et al. 1996, Short and Sharpe 2020). Its stronghold appears to be in the north and north-central part of the range, with observations becoming less frequent towards the south (per eBird 2023).
Based on density estimates of congeners, the national population in Colombia is inferred to number 2,500-9,999 mature individuals (Renjifo et al. 2014). While the majority of the population is found in Ecuador, there are no density or population estimates available. Based on data from Colombia, the overall population is tentatively suspected to number 10,000-19,999 mature individuals, though a precise estimate is urgently required.

Trend justification: The population is suspected to be in decline, mainly as a consequence of habitat loss and illegal trapping (Renjifo et al. 2014, Basantes Hernández and Yánez Moretta 2021).
Tree cover loss within the range is low (2% over three generations; Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). However, for the Colombian part of the range the rate of overall habitat loss is estimated at 7.05% over the ten years to 2014 (Renjifo et al. 2014). This equates to 12% over three generations (17 years). Contrary to the value presented by Global Forest Watch, which measures the loss of tree cover only, Renjifo et al. (2014) report the rate of overall habitat change, which includes the rate of loss of mature, successional and partially degraded forests used by this species. Habitat loss continues to threaten the species (Basantes Hernández and Yánez Moretta 2021), and even though Colombia forms a small part of the range it is precautionarily suspected that this rate is representative for the entire range. Despite being occasionally found in selectively logged and mature secondary forests the species is highly forest-dependent and strongly relies on large trees and standing deadwood for nesting (Short and Sharpe 2020) and as such, population declines may exceed the net rate of habitat loss. The impact of trapping on the population size has not been quantified, but illegal trade is described as 'intensive' in large parts of the range (Renjifo et al. 2014). Precautionarily, the population decline is therefore here placed in the band 20-29% over the past three generations.
