Population justification: The population size is considered to be <50,000 mature individuals (Partners in Flight 2020), thus it is placed in the band 20,000-49,999 mature individuals.

Trend justification: The population is undergoing a significant decline owing to habitat destruction and hunting for food (Gomes et al. 2020, Partners in Flight 2020, Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). It is considered to be threatened in Mexico, with previous research showing that 50% or more of its population had been lost in the country during the last 100 years (Berlanga et al. 2010, SEMARNAT 2010). It is also currently on the Watch List of Partners of Flight (2020) and considered rare in other parts of its range (Gomez et al. 2020). In the past three generations (15 years; Bird et al. 2020), there has been an 18% loss in tree cover over the species' range (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). Given the additional threat from hunting, population declines were likely to have been steeper than the rate of forest loss, therefore amounting to a population decline of 20-29% over the past three generations. In recent years, forest loss is now accelerating and the average annual rate over the past five years is equivalent to c. 31% over three generations (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). With a small additional impact suspected from hunting, which is unlikely to cease, the rate of reduction over a three generation period including both the past and the future is suspected fall between 30-39%. This rate is also suspected to apply over the future three generations.
