Population justification: The global population size has not been quantified, but this species is described as 'uncommon' (Stotz et al. 1996).
Trend justification: The species is suspected to have undergone declines owing to the effects of hunting and egg-collection, with overgrazing perhaps being less significant but still having a negative impact.
