Abstract: In a study of contents of the western gulls' regurgitation pellets, Pollicipes polymerus, the gooseneck barnacle, was shown to be the most abundant material. The chiton Nuttalina californica was also found to occur in the pellets in relatively high frequency, indicating that the western gull is a major predator on Nuttalina, perhaps taking 15% of the population around the study site per breeding season.
