The bird was rescued after being exposed in an oil spill in the Gulf of Mexico caused by the explosion of BP's Deepwater Horizon oil platform more than three weeks ago. At nearly every step since the Deepwater Horizon exploded more than a month ago, causing the worst oil spill in U.S. history, rig operator BP PLC has downplayed the severity of the catastrophe in the Gulf of Mexico.
