Fall migration is underway for many birds, including Common Nighthawks. These agile fliers can be seen now at dusk, wending their way south over fields and rivers in loose flocks of five to five-hundred. Most will spend eight months or so of their year in South America, which might more appropriately be called their "home" despite the fact that they nest and raise their young here in the U.S.
