Unlocking the Secrets Behind the Hummingbird's Frenzy - A captive Anna’s hummingbird feeds while hovering before an optical illusion in a reenactment of an experiment that illustrates just how heavily hummingbird flight depends on the bird’s visual perceptions. When this spiral rotates to create the illusion that the bird is moving forward, the bird shifts into “reverse gear”—and its beak slips out of the feeder.
