Justification of Red List category
This species has a large geographic range size (extent of occurrence >17 million km² in both the breeding and non-breeding seasons), and so does not approach Criterion B thresholds. It also has a large population size estimated at 500,000-1,000,000 mature individuals, and so does not approach Criteria C or D thresholds. Considering its population trend over three generations (c. 11 years), the data presented in Smith et al. (2023) indicate a slow decline of c. 14%, although the underlying interannual trend data suggest that numbers at the end of that study period (in 2019) were similar to the medium-term average. There is some evidence of similar slow declines from the Pacific coast (Migratory Shorebird Project, unpublished data) and from the Breeding Bird Survey (Ziolkowski et al. 2022), although the latter also suggests stability in recent years, while the Christmas Bird Count (Meehan et al. 2022) has recorded a sustained increase. While the population is precautionarily suspected to be declining, there is no evidence that the population is declining at a rate approaching Criterion A thresholds. Hence, the species continues to warrant listing as Least Concern.
