Every year, two to three million starlings meet in the Italian city of Rome to spend the winter. It is slightly warmer in the city than in the surrounding countryside, which is why the birds fly toward the city center each evening to roost. During the day, they forage for food around town. Peregrine falcons hunt the starlings as they circle over their roosting site before dusk in huge swarms, called murmurations. To confuse the predators, they twist, turn, swoop, and swirl in spectacular flight formations. Ingo captured the rapidly changing shapes within aesthetic images.
