Justification of Red List category
This species has a large geographic range size (extent of occurrence >16 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 (250,000 mature individuals; Partners in Flight 2023), and so does not approach Criteria C or D thresholds. Considering its population trend over three generations (c. 18 years), the data presented in Smith et al. (2023) indicate a slow decline of c. 10%, albeit with large confidence intervals. This is broadly consistent with evidence of similar rates of decline from the Breeding Bird Survey (c. 7%; Ziolkowski et al. 2022), eBird (c. 6%; Fink et al. 2023) and Partners in Flight (2023; c. 15%). In recent years, a steeper decline has been recorded on the Pacific coast by the Migratory Shorebird Project (unpublished data), although this covers a relatively small proportion of the population. Conversely, data from the Christmas Bird Count (Meehan et al. 2022) indicate a stable population. Although the population is declining, it does not currently appear to be declining at a rate approaching Criterion A thresholds. Hence, the species continues to warrant listing as Least Concern.
