Hundreds of thousands of sandhill cranes stop along the Platte River in the midwestern U.S. to rest and refuel on their annual migrations. They often travel at night, so the ACAS system's aim is to help cranes and other birds see power lines and other human structures in the dark, enabling them to safely reach their destinations.
