Xema
Sabine’s Gull (Xema sabini)
A distinctive species breeding in the arctic and subarctic: along the coasts of western and northern Alaska east across arctic Canada to the high-arctic zone in Greenland. From there further east to Spitsbergen and to Siberia. Winters much further south in subtropical and tropical coastal upwelling zones.
While this species is considered monotypic by the IOC, BoW recognised four subspecies: palaeartica from Spitsbergen east to the Taymyr Peninsula and Lena Delta; tschuktschorum on the Chukotskiy Peninsula; woznesenskii from northeast Siberia to Alaska; and sabini from arctic Canada to eastern Greenland.
