For the first time, the tracking data of the Pacific common eider Somateria mollissima v-nigrum breeding in the Asian part of the range was obtained. Usage of light geolocators makes it possible to determine the migration periods and main wintering grounds. Chukotka breeding eiders spread to winter over the Bering Sea: two females wintered offshore of the Chukotka Peninsula (Russia) and one female – offshore the Yukon–Kuskovim Delta (Alaska, USA).
