Population justification: The population size has not been quantified owing to recent taxonomic splits.

Trend justification: No trend data are available, but the given the apparently severity of threats including hunting for feathers and food, egg collection and habitat loss and degradation, the species is precautionarily suspected to be undergoing a rapid decline over three generations (50 years).
