Species: Delphinapterus leucas

A series of beluga whale (Delphinapterus leucas) sightings in southern Puget Sound in October 2021, added a new set of records for the species in this region. The 2021 event represents the longest period of time a beluga has been observed so far south of Alaska, in the eastern North Pacific. This may have just been an isolated event of a single extralimital individual. Alternatively, it may suggest a potential range expansion that could portend future increased visits by this species in the Pacific Northwest, especially if warming of Arctic waters continues.
