Population justification: Based on PRISM surveys, the population in the Canadian Arctic was estimated to number c.600,000 breeding birds (Bart et al. in prep.). In Alaska, USA, similar surveys found 31,000, but large portions of both countries were not surveyed. Bart et al. (in prep.) used a total estimate of 800,000 but conceded that this 'may represent an overestimate if key habitats were not searched uniformly', and in any instance this total represents a considerable increase on the 200,000 estimated by Andres et al. (2012). To account for these uncertainties, the global population size is estimated to be 500,000-1,000,000.

Trend justification: Considering its population trend over three generations (c. 11 years), the data presented in Smith et al. (2023) indicate a 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 There is some evidence of similarly slow declines from the Pacific coast (Migratory Shorebird Project, unpublished data) and from the Breeding Bird Survey (Ziolkowski et al. 2022), although the latter also suggests stability in recent years, while the Christmas Bird Count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. Overall the trend is precautionarily determined to be declining.
