At Sea Distribution of Spectacled Eiders: A 120-Year-Old Mystery Resolved

ABSTRACT.-The at-sea distribution of the threatened Spectacled Eider (Somateria fischeri) has
remained largely undocumented. We identified migration corridors, staging and molting areas, and
wintering areas of adult Spectacled Eiders using implanted satellite transmitters in birds from
each of the three extant breeding grounds (North Slope and Yukon-Kuskokwim Delta in Alaska and
arctic Russia). Based on transmitter locations, we conducted aerial sur­ veys to provide visual

Sea Duck Research at the Centre for Wildlife Ecology

The Centre for Wildlife Ecology has several studies underway that address conservation issues affecting sea ducks along the Pacific coast. The issues, species, and populations being studied are shared concerns of the Centre for Wildlife Ecology, the Canadian Wildlife Service, and agency and academic collaborators throughout North America.

Alaska-Yukon Waterfowl Breeding Population Survey 2010

Waterfowl breeding conditions within the survey area depend largely on the timing of spring
phenology. A very mild spring breakup occurred in Interior Alaska, due to very low winter snow
fall resulting in lower than normal water levels across the Interior. Spring breakup, while
initially delayed, occurred normally throughout the majority of Coastal Alaska.
