Named in honor of the lost space shuttle crew, Challenger has performed free-flights during the USA's National Anthem at hundreds of events coast to coast, raising substantial public awareness for the Bald Eagle protection cause. He is the first Bald Eagle in American history trained to free-fly during the singing of the Star Spangled Banner. He has helped educate millions of people about the need to protect the USA's National Bird. — Challenger is a non-releasable Bald Eagle cared for by the non-profit American Eagle Foundation. Since 1991, this majestic bird has been a free-flying educational ambassador for his recovering species in the wild. He was blown from his Louisiana nest in a storm at five weeks of age — was rescued and hand-raised by well-meaning people. As a result, he became human-imprinted for life.
