The U.S. is currently experiencing a peak in south-north bird migration, with Indiana seeing millions of birds flying over the state each night.

BirdCast, an interactive map of bird migration, reported over half a billion birds in the sky at once on Sunday night, with a high concentration over the Midwest.

The Indiana DNR urges you to support migrating birds by minimizing light pollution.

Birds migrate at night to avoid overheating and predators.

Turning off outdoor lights helps them navigate safely.
