Population justification: The global population is estimated to number over 340,000 mature individuals (Wetlands International 2015, Partners in Flight 2019). The European population is estimated at 1,100-2,100 pairs, which equates to 2,100-4,100 mature individuals (BirdLife International 2015).

Trend justification: The overall population trend is stable, although some populations have unknown trends (Wetlands International 2015, Partners in Flight 2019). The small European population (c.10% of global range) is estimated to be increasing (BirdLife International 2015). Increases of Sabine's Gull have also been observed in Alaska (Swaim 2017, Amundson et al. 2019).
