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

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.

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.
The North American Bird Banding Program is jointly administered by the United States Department of the Interior and the Canadian Wildlife Service . Their respective banding offices have similar functions and policies and use the same bands, reporting forms and data formats. Joint coordination of the program dates back to 1923.
The Atlantic Seaduck Project is being conducted to learn more about the breeding and molting areas of seaducks in northern Canada and more about the feeding ecology of seaducks on wintering areas, especially Chesapeake Bay. Satellite telemetry is being used to track surf scoters wintering in Chesapeake Bay, Maryland, and black scoters on migrational staging areas in New Brunswick, Canada, to breeding and molting areas in northern Canada
On 24 March 1989, the T/V Exxon Valdez ran aground on Bligh Reef in Prince William Sound, Alaska, spilling approximately 41 million liters of crude oil (Piatt and Lensink 1989, Piatt et al. 1990). Subsequent wind and ocean currents spread the oil southwest through Prince William Sound (PWS), along the Kenai and Alaska Peninsulas, and along the Kodiak Archipelago. Much of the oil was deposited in nearshore intertidal and subtidal habitats (ADEC 1992, Neff et al. 1995), which are of importance to a large number of vertebrates including molting and wintering waterfowl.
