The Sooty Shearwater (Puffinus griseus) is the most abundant, and perhaps the most conspicuous seabird off the coast of California during the spring – summer. The shearwater’s affinity for highly productive coastal waters influenced by upwelling often leads to predictable, and extremely aggregated flocks. Flocks range in size from several 1,000s to over a 100,000. The arrival of millions of shearwaters to California each year is a seasonal phenomenon that is well observed by thousands of people living in and visiting coastal communities in California. The distribution of high concentrations of shearwaters between the populated coast and heavily traveled offshore shipping lanes, place this species at a high risk from chronic oiling (urban runoff), catastrophic oiling (spills), and pollution.
