Population justification: The global population is suspected to number 50,000-499,999 mature individuals (Partners in Flight 2019).
The population structure has not been investigated. Based on its disjunct range, it is likely that the species forms several subpopulations.

Trend justification: The population is considered to be in decline owing to ongoing habitat destruction and unsustainable levels of hunting, both subsistence and commercial, with the species having disappeared from much of its Central American range (del Hoyo et al. 1994; Partners in Flight 2019; Gilbert and Schulenberg 2020). Over the past three generations (24 years; Bird et al. 2020), 14% of tree cover within the range has been lost (Global Forest Watch 2021). Although there is no information on the impact of hunting on the population size, it is likely that population declines are considerably faster than the rate of tree cover loss. Therefore, the rate of decline is suspected at 20-29% over three generations.
