Population justification: The population was estimated as c.1.7 million in 2012 (Andres et al. 2012) but was recently substantially revised upwards to c.6.2 million (3.27-9.07 million) (Bart et al. in prep.), with the latter covering almost the entire species' breeding range and therefore accepted here. This value is based on the Program for Regional and International Shorebird Monitoring (PRISM) surveys on the breeding grounds (Bart and Smith 2012, Smith et al. in prep.). These surveys target breeding pairs in suitable breeding habitat, hence the values derived are considered to relate to mature individuals.
Trend justification: Not well understood, but recent migration count data from the Atlantic coast indicate potentially rapid declines, albeit with high uncertainty. Smith et al. (2023) estimated a population reduction equivalent to 49.0% over three generations, though with wide confidence intervals between a reduction of 2.4% and 74.6%. However, in sixty years of monitoring of breeding populations at a site in Alaska (where it must be acknowledged only a very small minority of the global population breeds), Taylor et al. (2018) found no change in breeding density between 1951 and 2012. The rate of reduction is here estimated to fall within the wide band of 0-75%, with the best estimate of 40-49% over three generations to cover the median rate of reduction estimated by Smith et al. (2023). This data is also used in the Avian Conservation Assessment Database December 2023 update (Partners in Flight 2023).
