On a heat morning in October 2024, Dave Willard, the retired chook collections curator for Chicago’s Area Museum of Pure Historical past, walked briskly alongside a glassy façade on the Lake Michigan shoreline, searching for fallen birds. The constructing product of glass is McCormick Place, the conference middle notorious to birders for being the place the place near 1,000 migrating songbirds met their deaths on Oct. 5, 2023.
Willard has taken walks like this one practically each morning in the course of the spring and fall migration seasons for the final 40 years, documenting the birds that crash into the constructing’s home windows. He usually collects practically 1,000 lifeless birds at McCormick Place over the course of a yr. This previous autumn, nonetheless, Willard says he discovered solely six.
The distinction seems to be the tiny white circles spaced each two inches alongside everything of McCormick Place’s 120,000 sq. toes of glassy floor. The markers had been utilized as a part of a $1.2 million challenge final summer time carried out by the Metropolitan Pier and Exposition Authority, which owns and operates McCormick Place, to keep away from one other avian disaster.
“Each migration is completely different,” Willard says, “however the prognosis is sweet.”
The markers look like doing what they’re meant to do—hold birds from slamming into the glass. On a number of heavy migration days in late August and early September, when effectively over 100 lifeless birds had been collected on the base of skyscrapers throughout town by the nonprofit group Chicago Hen Collision Screens, Willard discovered just one or two lifeless birds at McCormick Place. One of many volunteers in Willard’s survey effort even reported seeing a chook fly close to the constructing and veer away because it obtained nearer.
“If this actually works right here, and I’m ready till migration is over to say if it actually works, then let’s go on to the following worst constructing, proper?” says Willard.
McCormick Place has lengthy had a popularity as one of many worst bird-killing buildings in Chicago. The constructing’s location proper on the lakeshore, in the midst of a migratory pathway, makes it significantly lethal to migrating American Tree Sparrows, juncos, Yellow-rumped Warblers, and dozens of different migratory species that journey by town by night time.
For a number of years MPEA has participated in Chicago’s Lights Out program, a voluntary effort to cut back chook strikes by turning lights off throughout migration, however the conference middle solely went darkish when no employees, customer, or purchasers had been current. After final October’s catastrophe, McCormick Place officers drew the curtains contained in the conference middle to cowl up the inside lights throughout chook migration. The markers are a extra everlasting resolution.
“MPEA has at all times strived to be a great neighbor and environmental steward, each inside and out of doors our campus,” stated MPEA CEO Larita Clark in a press launch. “Once we discovered of the reported mass collision occasion final yr, we knew that we wanted to shortly make extra enhancements to guard native and migratory birds as they cross McCormick Place.”
The MPEA labored with Feather Pleasant, a Toronto-based firm that makes scientifically examined bird-deterrent merchandise for glass, on the challenge. Installers labored from June to August, rigorously transferring the markers from the movie to the home windows throughout everything of the outside glassy floor on McCormick Place. Feather Pleasant executives now say that different constructing homeowners in Chicago are coming to the corporate to ask concerning the product that MPEA placed on McCormick Place.
“Once we first began, it was laborious to get anybody to even take into consideration doing one thing like this,” says Feather Pleasant vp Paul Groleau, who notes that the corporate sells merchandise for residential buildings as effectively. “Consciousness is at an all-time excessive.” Extra about methods to make your house’s home windows safer for birds.
That recognition comes not a second too quickly, says Chicago Hen Collision Screens director Annette Prince. She notes that town’s municipal codes presently don’t require constructing homeowners and designers to make buildings chook pleasant, and {that a} new growth deliberate alongside the Chicago River—a brand new Bally’s On line casino—contains plans for an enormous glass façade.
Prince says that any new buildings in Chicago ought to incorporate bird-friendly glass from the beginning.
“Different cities are doing it, and so they haven’t collapsed right into a pile of mud as a result of they’re being chook pleasant,” she says. “I feel that we will have enticing structure and chook security. They don’t should be mutually unique.”
