Population justification: The global population size has not been quantified, but the species is described as 'fairly common' (Stotz et al. 1996).

Trend justification: The species is thought to be undergoing a decline owing to hunting and the loss and degradation of its habitat. Tree cover loss within the range has not exceeded 10% over the last three generations (15 years; Tracewski et al. 2016, Global Forest Watch 2020). Nevertheless, despite its tolerance of low levels of habitat conversion, the species also suffers from the degradation of the understory through cattle grazing, and it is susceptible to hunting (Gomes and Kirwan 2020). Therefore, the overall rate of decline is tentatively placed in the band 10-29% over three generations.
