Justification of Red List category
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence under 20,000 km² combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population size is extremely large, and hence does not approach the thresholds for Vulnerable under the population size criterion (under 10,000 mature individuals with a continuing decline estimated to be over 10% in ten years or three generations, or with a specified population structure). The population trend is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds under the population trend criterion (over 30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern.
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).
