Population justification: Previously the population was very roughly set as 1,000-100,000 individuals. The lower bound of this is unlikely given the size of the range and likely density of the species, but there is no reliable estimate of population size.

Trend justification: The population is declining owing to habitat destruction, intense egg collecting and hunting (del Hoyo et al. 1994). The rate of deforestation within the mapped range of the species has been 2.8% over 19 years (2001-2019 [Global Forest Watch 2020]), equivalent at the same average rate to 3.5% forest loss over three generations (23.5 years). As such, the species is suspected to be suffering a slow population reduction.
