Fly Like an Eagle?

Like many people, I am fascinated by bird flight. Unlike most people, I get to study flight of Golden Eagles for a living. These large birds move through the landscape primarily by soaring—a style of flying where they hold their wings outward and rarely flap, saving them considerable energy. Instead of flapping, they rely on rising air currents to gain altitude.
