A female Golden Eagle flies from her rocky perch as an early season snowfall blankets Wyoming’s sagebrush steppe. At liftoff, the bird spreads her wings and takes a leap. It takes the eagle the first few wingbeats to tuck her legs under and achieve the streamlined shape needed for efficient flight. Once airborne the bird repeats a flap-flap-glide sequence in an impressive example of powered flight. As she battles the crosswind, she uses her fully fanned tail to steer.
