FILE - In this Sunday, May 9, 2010 file picture, an oil-soaked bird struggles against the side of the HOS Iron Horse supply vessel at the site of the BP Deepwater Horizon oil spill in the Gulf of Mexico off the coast of Louisiana. An April 20, 2010 explosion at the offshore platform killed 11 men, and the subsequent leak released an estimated 172 million gallons of petroleum into the gulf. (AP Photo/Gerald Herbert) less
