Population justification: The species has a large estimated population size of 660,000 mature individuals (Partners in Flight 2023).

Trend justification: Considering this species' population trend over three generations (c. 11 years), the data presented in Smith et al. (2023) indicate a slow decline of c. 4%, albeit with interannual fluctuations. This is broadly consistent with the c. 11% decline recorded by the Breeding Bird Survey (Ziolkowski et al. 2022), as part of a long-term decline. Conversely, data from the Christmas Bird Count (Meehan et al. 2022) indicate a stable non-breeding population in the southern USA (following a slow long-term increase there, possibly due to short-stopping under climate change), while eBird (Fink et al. 2023) suggests a c. 6% increase on the breeding grounds. Overall the trend is suspected to be probably stable.
