It's peak spring migration season in Chicago, and residents can help birds arrive safely by turning their lights off at night
CHICAGO (WGN) — As the weather warms and summertime approaches in Chicagoland, you'll hear the chirping of more and more birds. That's because millions are coming to the area during the peak spring migration season. And to help them arrive safely, area residents can turn their lights off at night. According to BirdCast's migration dashboard, most birds pass through the contiguous U.S. from mid-April to mid-May. For our area, the peak migration time is right now. An estimated 2,270,400 birds passed into Cook County overnight Monday into Tuesday, according to BirdCast. The peak was reached around 2:30 a.m. Tuesday, when an estimated 425,100 birds crossed into Cook County, flying at an altitude of 2,200 feet and a speed of 30 miles per hour. Magnitude 3.3 earthquake reported in Illinois overnight BirdCast says nearly 31 million birds have been estimated to have migrated into Cook County from March 1 through the overnight hours of Monday into Tuesday. The highest nightly traffic thus far was recorded on Friday, May 9, when an estimated 346,900 birds were in flight, on average, at one time. These high traffic totals will keep Chicago on 'high migration alert' this week. You can check HERE on BirdCast for alert details. Birds usually begin to migrate 30 to 45 minutes after sunset, according to BirdCast, with the greatest number in flight two to three hours later. So with such large numbers of birds migrating at night, area residents are asked to help protect them by turning off all non-essential lighting from 11 p.m. until 6 a.m. while the 'high migration alert' is in effect, which includes overnight Tuesday into Wednesday. According to BirdCast, bright lights attract and disorient nocturnally migrating birds, potentially causing fatal collisions with buildings or exposure to additional day-time hazards. In cities like Chicago, for example, the windows of high-rise buildings can pose great danger for migrating birds, a problem that's come into focus during the fall migration, when birds sweep south following the Lake Michigan shoreline. About 1,000 migrating songbirds were killed over a single night on Oct. 4-5, 2023, after flying into the windows of McCormick Place. In response, McCormick Place installed bird-safe window film over its two football fields' worth of glass windows, which was in place in time for the 2024 fall migration season.

Why are there no lights on at the Gateway Arch?
ST. LOUIS – If you're driving down the highway towards the city and notice you don't say to yourself, 'Look, there's the Arch!' because you can't see it in the skyline, don't worry—it's still there. But throughout the month of May, the Arch will be dark. May marks the peak of bird migration when they travel north for the summer time. The Gateway Arch is located directly in the pathway these birds use, so lights are turned off to help protect them as they travel through. According to the Arch, more than 320 different bird species utilize the Mississippi Flyway—where the Arch is located—during the migration seasons in May and September. Close Thanks for signing up!

It wasn't until May 2023 when the Arch started going dark for the entire month, the National Park Service said. Last fall, crews installed an acoustic logger with the help of the organization Lights Out Heartland. This technology catches the nocturnal flight calls while on Arch grounds. Throughout a two-week period set up, the logger caught nearly 600 potential bird calls. At least ten bird species were able to be identified through the sounds, with the most common being the Least Sandpiper and American Redstart. Lights at the Arch will be back on June 1.

Nearly 600 bird calls detected at Arch during migration period
ST. LOUIS – As another migration period is approaching, the Gateway Arch National Park shared details of what birds are flying through St. Louis during these times Thursday. According to a social media post from the park, crews installed an acoustic logger this past fall with the help of the organization Lights Out Heartland. This technology catches the nocturnal flight calls while on Arch grounds. Throughout a two-week period set up, the logger caught nearly 600 potential bird calls. At least ten bird species were able to be identified through the sounds. The park also stated that the most common bird call came from the Least Sandpiper and American Redstart. Every May and September, birds make their migration north for the summer and south for the winter. During these times of high activity, the Arch shuts off its lights to remove any potential disorientation it could cause to the birds. Copyright 2025 Nexstar Media, Inc. All rights reserved.
