Justification of Red List category
This species has a large geographic range size (extent of occurrence >8 million km² in both the breeding and non-breeding seasons), and so does not approach Criterion B thresholds. It also has a large estimated population size (460,000 mature individuals; Partners in Flight 2023), and so does not approach Criteria C or D thresholds. Considering its population trend over three generations (c. 14 years), the data presented in Smith et al. (2023) indicate a slow decline of c. 16% (with a wide confidence interval), although the underlying interannual trend data suggest a fluctuating population. There is some evidence of recent declines from the western USA and Mexico (Migratory Shorebird Project, unpublished data) and from eBird (Fink et al. 2023), but also consistent evidence of a modest overall recent increase in North America from both the Christmas Bird Count (Meehan et al. 2022) and the Breeding Bird Survey (Ziolkowski et al. 2022). The population trend is therefore considered unknown, but there is little evidence the species is declining at a rate that approaches Criterion A thresholds. The species is therefore listed as Least Concern.
