Population justification: The population is estimated at 45,000 mature individuals (Rosenberg et al. 2016), equating to 67,500 individuals in total.

Trend justification: Between 1970 and 2014, the species is suspected to have declined by 95% (Rosenberg et al. 2016). This equates to an annual decline of 6.6%, or a decline of 51.1% over 3 generations (10.5 years).
