They group has one American Bald Eagle in their possession, named Chapin. It was born into captivity in the Netherlands so U.S. Fish and Wildlife Service agents need not worry about the legality. We were able to watch it fly a number of times, and due to the rather brisk winds, it seemed to take almost no effort to fly. It merely had to open it's wings and the wind would propel it into the sky. I can tell you it was a thrilling sight to see it soar down through the valley below, disapear, and suddenly reapear behind you at a great height, all the while seldom even flapping it's wings. And then it would gracefullybegin it's descent, legs outstretched, tailfeathers moving like a rudder to guide him to the waiting arm of his handler. There he would receive a reward of a raw chicken leg.
Above, you can see one of the two falcons landing on the arm of his handler.
And again, same thing, different handler. These falcons, perhaps because of the high winds and effortless nature of their flight, did not return as expected. You could see the concern on the faces and in the voices of the handlers. It was "C'est pas normal." They appeared when the eagle was flying, and did not reappear by the end of the show. The handlers indicated that they would just have to go and find them. It looked like to me that each bird had a GPS unit attached and would be able to be tracked down eventually.
