in table 6 are probably somewhat misleading as many immatures may have been recorded as Herring Gull type. California Gulls are abundant along the coast. Due to easy confusion with Herring Gulls, all sightings were grouped with Herring-type. Ring-billed Gulls were not identified on any part of the survey, but their presence in good numbers at Port Hueneme suggests that they are a regular bird along the coast. Bonaparte Gulls were abundant in some coastal areas and absent from others. Both adults and immatures were noted. Heerman's Gulls are easily identified. Most were seen off Point Conception and seemed to be attracted to large patches of sargassum. None were seen far off shore. Black-legged Kittiwakes were abundant along the coast north of Pt. Concept- ion, but scarce to the south. Whether this was due to land being closer in the southern area or due to some other factor is not suggested. Alcids Cassin's Auklets, Xantus Murrelets, and Rhinoceros Auklets were all noted in the coastal areas. As suggested in the grid discussion, numbers are probably higher than observations suggest.
