SPRING MIGRATION OF SPECTACLED EIDERS AT CAPE ROMANZOF, ALASKA

Abstract

The Spectacled Eider (Somateria fischeri) was described for science from St. Michael, Alaska, over 150 years ago. However, its nonbreeding range remained unknown until recently, when concentrations of molting and wintering eiders in the Bering and Chukchi Seas were finally revealed by satellite telemetry (Petersen et al. 1995, 1999).
