Population justification: The species has a large estimated population size, with at least 1,200,000-1,400,000 mature individuals in Arctic Canada alone (Smith et al. in prep., Bart et al. in prep.).The European population (exclusively individuals breeding in Greenland) is estimated at 500-1,000 pairs, which equates to 1,000-2,000 mature individuals (BirdLife International 2015). The population in Russia has been estimated at < c.100,000 breeding pairs and < c.1,000 individuals on migration (Brazil 2009). The population in Alaska has not been estimated but is said to be 'small' (Bart et al. in prep.). The global population is estimated at 1,200,000-1,500,000 mature individuals to account for birds breeding outside of Canada.

Trend justification: Considering its population trend over three generations (c. 13 years), the data presented in Smith et al. (2023) indicate broad stability, albeit with some interannual fluctuations. This is consistent with the recent trend based on data from the non-breeding season by eBird during 2014-2021 (Fink et al. 2023).
