Population justification: The global population is estimated to number 120,000 mature individuals (Kushlan et al. 2002).

Trend justification: The population is undergoing a small decline (Kushlan et al. 2002, Partners in Flight 2019), which is thought to be caused by climate change and human disturbance.
