Population justification: The population is suspected to number fewer than 50,000 mature individuals (Partners in Flight 2020), thus it is placed in the band 20,000-49,999 mature individuals here.

Trend justification: The population is suspected to be in moderate decline owing to ongoing habitat destruction and low hunting pressure (del Hoyo et al. 1994, Partners in Flight 2020, Chávez-León 2020). Over the past three generations (15.3 years; Bird et al. 2020), 5% of tree cover has been lost within the range (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). To account for additional impacts of hunting, the rate of population decline over the past three generations is here placed in the band 1-9%. Tree cover loss has been increasing since 2016, to a rate equivalent to 8% over three generations (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). Accounting for hunting pressure, the population decline over the next three generations is therefore placed in the band 1-19%.
