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 and has flown in front of 4 American Presidents.
He has helped educate millions of people about the need to protect the USA's National Bird.
Challenger's nest was blown from the tree (in Louisiana) about 20 years ago -- a fisherman happened by in a boat, saw the nest down with the parents flying up above. At that time, Challenger was about 5 weeks old. The fisherman rescued the baby, cared for him and then tried to release him when he was old enough, but Challenger did not know how to take care of himself because he was human-imprinted.
Osceola is one of the birds at the American Eagle Foundation. Challenger and Osceola live at the same facility (the American Eagle Foundation) in Pigeon Forge, TN along with many other non-releasable eagles and other birds of prey.
