Over 470 Million Birds Migrating North Across the United States on the Night of May 14 2026 With Doppler Radar Capturing Massive Movement and Lights Out Alert Issued Nationwide
WASHINGTON, D.C. — A major bird migration event is underway across the United States on the night of May 14, 2026, with over 470 million birds currently moving northward in one of the largest single-night migration pulses recorded this season. The scale of the movement is so significant that Doppler radar networks across the country are actively depicting the birds in flight, distinguishing this as a landmark migration night for the region.
Doppler Radar Captures Unprecedented Bird Movement Across the Midwest
Radar imagery captured at 11:40 PM ET shows widespread green returns blanketing a large portion of the central and eastern United States, with the signatures confirmed as migrating birds rather than precipitation. The heaviest concentration of radar returns is visible across a north-south corridor through the central Midwest, with intense red and yellow signatures indicating the densest clusters of bird activity overhead.
The circular bloom patterns visible across multiple radar sites are a well-documented phenomenon during peak migration nights, occurring as birds take flight simultaneously from roosting areas after darkness falls. These blooms expand outward from their origin points as the birds gain altitude and disperse into their northward flight paths.
City-Level Bird Forecast Highlights Scale of the Migration Event
Bird forecast data for major cities underscores the volume of migration activity passing through populated areas on this night. Kansas City is tracking approximately 90,200 birds in migration, while Chicago is seeing an estimated 73,500 birds moving through its corridor. Des Moines is recording around 34,300 birds as part of the broader northward push across the Midwest.
These city-level figures represent only a fraction of the 470 million total birds in flight nationwide, reflecting the extraordinary geographic breadth of this migration pulse as species move en masse toward northern breeding grounds during peak spring migration season.
Lights Out Alert Issued to Protect Migrating Birds Through the Night
A Lights Out Alert has been issued urging residents across affected areas to dim or turn off all non-essential outdoor lighting between 11:00 PM and 6:00 AM. Artificial light is known to disorient migrating birds, causing them to veer off course, collide with structures, or exhaust themselves circling illuminated areas rather than continuing their northward journey.
Public cooperation with the Lights Out Alert during peak migration nights significantly reduces bird mortality across urban and suburban areas. Residents are encouraged to take simple steps such as turning off decorative exterior lights, closing blinds to reduce indoor light spill, and postponing any non-essential outdoor lighting use until after the migration window passes at 6:00 AM.
