On 5 January 1996, at about 09:45, Weintraub, Carolyn Raynesford, Lucy Lee, and Irene Horiuchi found an immature Ivory Gull (Pagophila eburnea) on a gravelly beach at Doheny State Beach, Dana Point, Orange County, California (33°27'33"N, 117°40'31"W). Later, the bird flew to the nearby mouth of San Juan Creek, where it was subsequently seen by approximately 25 observers, including San Miguel.
