Population justification: The species has a large estimated population size of 190,000 mature individuals (Partners in Flight 2023).

Trend justification: Considering its population trend over three generations (c. 10 years), the data presented in Smith et al. (2023) indicate a rapid decline of c. 50%, albeit with interannual fluctuations. Conversely, the Breeding Bird Survey (Ziolkowski et al. 2022) recorded a c. 5% increase over the same period, as part of a slow long-term increase. This is mirrored by data from the Christmas Bird Count (Meehan et al. 2022), which indicate an increase of c. 17% in the non-breeding population in the southern USA (following a slow long-term increase there, possibly an artefact of short-stopping because of climate change). Partners in Flight (2023) infers that the most likely overall trend is a c. 11% increase. Overall, because of discrepancies in the data, the trend is set to unknown.
