Population justification: In 1994-1997, 3,840 individuals were counted (Garnett and Crowley 2000). However, the population has recently declined by >50% and in 2009 only 1,486 birds were counted (Bryant 2010). The number of mature individuals is therefore likely to be between 1,000-1,500.

Trend justification: In 1994-1997, 3,840 individuals were counted (Garnett and Crowley 2000). However, the population has recently declined by >50% and in 2009 only 1,486 birds were counted (Bryant 2010). The global population is thus estimated to have declined by 50-79% in three generations (12 years).
