On 10 January 1977, while conducting marine bird and mammal surveys in the Southern California Bight, we observed a Blue-faced Booby (Sula dactylatra). To our knowledge this represents the first record of this species from the Pacific coast of the United States. All other Blue-faced Booby records over coastal waters of the U.S. are from the southern Atlantic coast and along the coast of the Gulf of Mexico (Palmer 1975).
