But that's just the beginning: the researchers also plan to train flocks of birds to fly in the tunnel to determine if the turbulence created by multiple pairs of wings affects each individual's flight. Plus, they're planning to install equipment that can visualize how the birds' muscles and bones move. Lentink believes that the data they'll gather can provide the necessary information to build better flying robots. In the future, he wants to use the wind tunnel to test the bird-like machines he's aiming to build, ones with wings that morph based on the current wind conditions.
