Population justification: This species is described as locally rare (Y. G. Molina Martínez in litt. 2023). In Colombia, a population density of 0.9-2.6 individuals/km2 could be recorded (Ríos et al. 2005, Santini et al. 2018). This density is however not believed to be representative for the entire range (E. Botero-Delgadillo in litt. 2023, Y. G. Molina Martínez in litt. 2023). The global population can therefore not be quantified. Based on the extremely large range however, the population is unlikely to be small.
Trend justification: The population is suspected to be in slow decline owing to habitat loss and hunting pressure, and the species has reportedly declined or disappeared in areas close to settlements (del Hoyo and Kirwan 2020, T. Donegan in litt. 2023).
Over three generations (23.4 years), c.7% of tree cover is lost within the range (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). However, as it appears to tolerate some degree of secondary and edge habitats (del Hoyo and Kirwan 2020), habitat loss may not be driving substantial declines. Hunting pressure varies throughout the range, but may be locally high (del Hoyo and Kirwan 2020); therefore, population declines are here tentatively placed in the band 10-19% over three generations.
