Contact: Pam Sanfilippo, 314-503-0184ST. LOUIS—The National Park Service has announced it will not illuminate the Gateway Arch at night throughout the month of May 2023 due to the spring bird migration season.
“St. Louis sits right beneath the Mississippi Flyway, a major migration highway,” said Jeremy Sweat, Superintendent, of Gateway Arch National Park. “For over a decade Gateway Arch’s exterior lights have been turned off for two weeks each May and September to help minimize the possible disorienting effect the lights may have on birds that migrate at night. As migration patterns have changed, this year the park will extend the lights off for the entire month of May.”
Gateway Arch National Park is both a building and program partner with Lights Out Heartland, an organization that works with partners to provide migrating birds safe passage through the Mississippi Flyway during the high-intensity migration months of May and September. According to the St. Louis Audubon Society, sixty percent of North American songbirds and forty percent of waterfowl (over 325 species) are anticipated to migrate this spring and fall.
The National Park Service began turning the Gateway Arch’s exterior lights off to protect migrating birds in 2002. The Arch’s exterior lights will be turned back on beginning the evening of Thursday, June 1, 2023, and the monument will be lit nightly thereafter.
