Population justification: The global population is estimated to number fewer than 50,000 mature individuals (Partners in Flight 2019), therefore it is here placed in the band 20,000-49,999 mature individuals.
Trend justification: The population is undergoing a small decline (Partners in Flight 2019), which is though to be caused by limited food availability.
