Pelagic distribution of Tufted Puffins—air and ship surveys: September-November. Miscellaneous alcids (Alie, Cepphus, Brachyramphus, Synthliboramphus, Ptychoramphus, Aethia, and Cerorhinca) Sixteen species of alcids, of which seven have al- ready been discussed in this paper, have been record- ed in the eastern Bering Sea. Distribution patterns of the remaining nine species are highly varied. All alcids feed primarily by pursuit diving, and euphau- siids, shrimp, and other crustaceans are the favored prey. The larger species include small fish in their diets. The Dovekie (Alle alle) and Black Guillemot (Cep- phus grylle), rare in the Bering Sea, are generally found only from St. Lawrence Island northward (Kes- sel and Gibson 1978). Pigeon Guillemots (Cepphus columba) and Kittlitz's Murrelets (Brachyramphus breuirostris) breed throughout the eastern Bering Sea. The former is fairly abundant and the latter uncom- mon. Both species tend to remain in bays and near- shore areas. Marbled Murrelets (Brachyramphus marmoratus). Rhinoceros Auklets (Cerorhinca monocerata), Cas- sin's Auklets (Ptychoramphus aleuticus). Whiskered Auklets (Aethia pygmaea), and Ancient Murrelets (Synthliboramphus antiquus) breed only on the Aleu- tian Islands, and their pelagic distribution rarely ex- tends north of 54-58° Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Hood, D.
