Abstract

Marbled Murrelets (Brachyramphus marmoratus) vary in the frequency with which they are associated with mixed species foraging flocks of seabirds. When foraging in the exposed waters of the outer coasts, murrelets are almost invariably found in pairs or small monospecific flocks. In protected waters, they are frequently associated with other species. The reasons for these differences are unknown. An increase in the number of gulls foraging in association with murrelets could be detrimental to the murrelets if it resulted in an increased rate of kleptoparasitism.
