A bald eagle soars over the Lower Klamath Wildlife Refuge in Oregon. The national bird of the United States, the eagle was critically endangered by hunting and pesticide poisoning. Its recovery from the 417 nesting pairs in 1963 to an estimated 9,789 pairs is a conservation success. It was taken off the USFWS endangered species list in June 2007. It will continue to be protected by law and monitored for at least five years. (© AP Images)
