Peak Spring Bird Migration Sends 201 Million Birds Northward Across Arkansas and the Central United States Tonight April 21
ARKANSAS — Peak spring bird migration is officially underway across the United States, with forecasters predicting that approximately 201 million birds will take to the skies and migrate northward on the night of April 21, 2026.
The migration intensity map shows the highest concentration of bird activity sweeping across Arkansas, the central plains, and extending into the eastern United States, marking one of the most significant single-night migration events of the spring season. Residents across the region are being asked to turn off outdoor and porch lights tonight to help birds complete their journey safely.
Scale and Scope of Tonight’s Migration Event
With 201 million birds predicted to be in flight simultaneously across the country, tonight ranks as a peak migration event by any measure. The migration intensity map shows the highest activity levels concentrated across a broad corridor stretching from Texas and Arkansas northward through the central plains and into the upper Midwest.
A second area of elevated migration activity is also visible across the southeastern United States, indicating a wide geographic footprint for tonight’s movement. Two primary northward migration pathways are active tonight, with one corridor tracking through the central plains and another sweeping through the eastern portion of the country.
Why Arkansas Is a Key Migration Corridor
Arkansas sits directly within one of the most heavily traveled bird migration corridors in North America. The state’s location along the Mississippi Flyway and its abundance of forests, wetlands, and river systems make it a critical passage zone for hundreds of species traveling northward from wintering grounds in Central and South America.
Forecasters specifically called out Arkansas by name in tonight’s migration alert, urging residents statewide to participate in the Lights Out initiative. Artificial lights are known to disorient migratory birds, causing them to veer off course, collide with buildings, or exhaust themselves circling lit areas during the critical overnight flight window.
How Residents Can Help Migrating Birds Tonight
The most impactful action residents can take is to turn off all non-essential outdoor lighting, including porch lights, decorative lighting, and bright interior lights visible through large windows.
Keeping pets indoors overnight and reducing window reflection hazards can also contribute to safer conditions for the hundreds of millions of birds passing through tonight across the region.
