<ul><li>Researchers have created a robotic bird model with real pigeon feathers to understand how birds manage to fly without a vertical tailfin.</li><li>The robot, PidgeonBot II, replicates avian movements by adjusting the shape of its wings and tail using real pigeon feathers and servo motors.</li><li>The bird-inspired control principles can inform the design of rudderless airplanes with minimal radar signature and elevated maneuverability and efficiency.</li></ul>
