Spring Migration of Eiders and Other Waterbirds at Point Barrow, Alaska
Birds migrating along the flaw lead at Point Barrow, Alaska were observed from 6 May to 4 June 1976. Little migration occurred until 25 and 26 May, when winds shifted from northeasterly to southwesterly and widened the lead. King Eiders (Somateria spectabilis) were the most abundant migrant; their m...
