A girl in a city rescues a sparrow confused by the city's night lights and learns how she can help: turn off lights, write letters, and put up window decals. The girl convinces her friends to help write to neighbors and business owners to explain the problem and "[ask] them to turn off their lights at night so the birds can see the starry map." The kids make art to hang in windows to keep birds from crashing into the glass. By the time the sparrows return north, the kids' campaign has worked and the birds have a safe trip.

Back matter includes more information about "birds, migration, and the dangers of light pollution," the Lights Out movement, and how to help. Even small actions can help! ( )
