How Lasers and a Goggle-Wearing Parrot Could Aid Flying Robot Designs

As the bird flaps its way through the water particles, its wings generate disruptive waves, tracing patterns that help scientists understand how animals fly. In a new study, a team of scientists measured and analyzed the particle trails that were produced by the goggle-wearing parrot's test flights, and showed that previous computer models of wing movement aren't as accurate as they once thought. When animals fly, they create an invisible "footprint" in the air, similar to the wake that a swimme
