Population justification: The global population has been estimated at 920,000 mature individuals (Partners in Flight 2020). In North America (USA and Canada), the total population size is estimated at 52,000 mature individuals (Partners in Flight 2020). The population trend in North America is unknown (Partners in Flight 2024). With no further data from other regions, the overall global population trend is therefore unknown.

Trend justification: The population trend is decreasing in North America (based on BBS/CBC data: Butcher and Niven 2007).
