Population justification: The total population is estimated at 1,500-2,500 individuals (H. G. Young in litt. 2002), roughly equivalent to 1,000-1,700 mature individuals.

Trend justification: This species's population is suspected to be decreasing rapidly, in line with extensive habitat loss and disturbance throughout its breeding range, exacerbated by hunting at both breeding and moulting sites.
