Population justification: Brooke (2004) estimated the global population to number c.100,000 individuals, which roughly equates to 66,666 mature individuals. Based on Boersma and Groom (1993) and Birdlife International (2009) estimates, Sato et al. (2010) describes the world population at a minimum of 130,000 pairs, which equates to 260,000 mature individuals. The population is therefore estimated at 66,666 - 260,000 mature individuals, rounded here to 65,000 - 260,000 mature individuals.

Trend justification: The population is expected to undergo a moderately rapid decline over the next three generations, owing primarily to the impact of introduced species.
