Californian brown pelicans fly over contaminated ocean waters and oil covered rocks near Refugio State Beach on the Californian coast in Goleta, California, United States, May 21, 2015. An oil pipeline that burst along the California coast, fouling pristine beach and stretch of ocean near Santa Barbara, is believed to have spilled up to 2,500 barrels of crude petroleum, about five times more than initially estimated, the pipeline company said on Wednesday.
