Pink-footed Shearwater, Puffinus creatopus
Pink-footed Shearwaters are larger and slower-flying than the more numerous Sooty Shearwaters, and seem to be willing to approach boats more confidently, and so are the most-photographed species of this family of splendid ocean flyers off the central California coast.
A Buller's Shearwater, second from the left, flying with six Pink-footed. Buller's are smaller, have a plain gray bill where the Pink-footed's is pink with a dark tip, and have more sharply outlined pure white underparts. Look down the linked Buller's page for another image of Pink-footed and Buller's flying together.
