Summary
Description
The winter feeding ecology of oldsquaw, whitewinged scoters, common murres and marbled murrelet was studied on Kachemak Bay, Alaska, from November 1977 through April 1978. The birds together ate a minimum of 79prey species. The sea ducks ate mostly benthic bivalves and gastropods, with fish and crustaceans sometimes important, while the alcids ate mostly pelagic and demersal crustaceans and fish. Birds wintering in Kachemak Bay appear to be at high risk from both acute and chronic oil spills.
