At least 1,000 birds died from colliding with one Chicago building in one day
From: The Guardian
At least 1,000 birds died from colliding into a single building in Chicago on Thursday, 5 October, as they migrated south to their wintering grounds. Volunteers are still recovering bird carcasses within 1.5 miles of McCormick Place, the largest convention center in North America, which is largely covered with glass.
“It's the tip of an iceberg but it's it's a huge, huge amount of birds we found both dead and injured,” said Annette Prince, director of Chicago Bird Collision Monitors, adding that this was the highest number of bird strikes that the group recorded from the grounds of one building in a single day.
From late Wednesday, 4 October, through early Thursday, 5 October, a peak estimate of 1.5 million birds were in the air over Cook county, home to the Chicago metropolitan area. Carcasses of Tennessee warblers, hermit thrush, American woodcocks and other varieties of songbirds were recovered.
“Not every bird that hits the window is going to leave behind a body,” said Brendon Samuels, who researches bird window collisions at the University of Western Ontario.
He noted that the true extent of affected birds will unravel over a couple of days as people continue to pick up birds around downtown Chicago.
“In fact, we often see birds collide with glass and they continue flying some distance away, seriously injured in ways that ultimately they won't survive past a few hours,” Samuels added.
Birds dying in large numbers in a small geographic area tends to occur during peak migration periods in spring and fall. Weather conditions like opposing wind, rain and fog can make it difficult for birds to orientate themselves, in addition to light pollution from cities that can draw them in and trap them among deadly structures.
“Anywhere you've got glass, you're gonna have birds hitting the windows,” said Bryan Lenz at the American Bird Conservancy. Annually, up to a billion birds die due to collisions, and in the case of Chicago, the dead and injured birds were most likely flying from Canada en route to South and Central America.
Everywhere birds visit, they perform essential ecosystem services that have economic value and are necessary for the functioning of ecosystems. Following major wildfires like those in Canada, birds that return to burned areas can disperse seeds and aid forest landscape regeneration. Global increases in temperatures contribute to the increase in insect populations, and birds that feed on them can help curb the issues that pose a threat for humans and food systems.
Of all cities in the US, Chicago's light pollution poses the greatest risk for migrating birds. Turning off building lights is one way to reduce fatalities. A 2021 study done in McCormick Place, the same site of Thursday's bird deaths, found that shutting off half the lights in large buildings can reduce collisions by six to 11 times. McCormick Place is a participant of the Lights Out Chicago program, which has buildings voluntarily switch off or dim lights at night unless someone is inside.
“It is important to understand that there is an event going on at Lakeside Center [part of McCormick Place] this week, so, therefore, the lights have been on when occupied. Once the space is unoccupied, the lights have been turned off,” said a representative from McCormick Place.
“It's a known hazard, and yet we still can't see action being taken about it,” says Prince.

“It is important to understand that there is an event going on at Lakeside Center [part of McCormick Place] this week, so, therefore, the lights have been on when occupied. Once the space is unoccupied, the lights have been turned off,” said a representative from McCormick Place.
麦考密克会展中心一名代表表示：“要知道，湖滨中心（Lakeside Center，麦考密克会展中心的一部分）本周正在举行一场活动，因此，当有人在场时，灯光一直是亮着的。一旦没有人，灯光就会被关闭。”

hazard
hazard /ˈhæz.əd/表示“危险（物），危害（物）”，英文解释为“something that is dangerous and likely to cause damage”如：a fire/safety hazard 火灾/安全隐患，举个🌰：The busy traffic entrance was a hazard to pedestrians. 那个繁忙的车辆入口处对行人来说很不安全。
