Population justification: The global population is estimated to number 1.4 million mature individuals (Partners in Flight 2019).

Trend justification: The population is suspected to be in decline owing to the impact of climate driven trophic shifts leading to the periodic or ongoing loss of accessible prey in certain areas of the species's range.
