Spectacled Eider x King Eider Hybrid

Spectacled Eider x King Eider Hybrid

-
Not yet spotted on Fladder
Spotted
This rare hybrid occurs between the Spectacled Eider (Somateria fischeri) and the King Eider (Somateria spectabilis), two large arctic sea ducks. Such a hybrid would exhibit a blend of the unique head patterns and body plumage characteristic of both parent species.
Where to spot
Potentially found in their overlapping breeding grounds in the Arctic, particularly northern Alaska and Siberia, or during migration along their shared coastal routes.
How to spot
Look for a mix of the Spectacled Eider's eye patches and the King Eider's distinctive frontal shield or knob, along with intermediate body plumage and bill coloration. Careful attention to head shape and bill structure is vital.
When to spot
Most likely observed during breeding season (summer) or migration periods (spring/fall) along their arctic migratory routes, when individuals are more dispersed and potentially encountering other species.
Hybrids between different eider species are extremely rare but can occur where their breeding ranges overlap, leading to unique and often puzzling individuals that challenge identification.
