Retired U.S. Coast Guard Adm. Thad Allen, national incident commander for the Deepwater Horizon response, addresses volunteers at the Hammond Bird Rehabilitation Facility, Aug. 12, 2010. After birds affected by the oil spill are brought into the facility, they are cleaned, fed, monitored and released back into the wild once they have been rehabilitated and strong enough to survive on their own.
