Migratory bird motion remains in full speed, and professionals are advising Chicagoans to switch off their lights in the evening to help secure the birds over the next couple of days from deadly window crashes.
Thousands of birds carpeted the sky last night, according to Annette Prince, director and president of Chicago Bird Collision Monitors, a not-for-profit committed to the break and security of migratory birds through everyday rescue efforts, when on Thursday Chicago experienced an extreme shift in wind patterns going up from the south, triggering waves of birds to travel through downtown searching for green space to settle.
Chicago lies on the Mississippi flyway, and birds travel through the city on their journey north towards Canada looking for a good location to nest and breed for the summertime.
On her method to work today, Prince discovered a little bird in the street, shocked.
“He couldn’t even move, he just sat there blinking and hurt,” she said. “It would have been just a matter of seconds before a car came and ran him over.”
Birds fly at night to secure themselves from predators. They browse utilizing the moon and stars, however synthetic light from city structures can alter their flight and make them crash into glass.
This early morning, the CBCM hotline was overloaded with calls from individuals around the city. Prince said after a night like Thursday, it’s not unusual for individuals to keep an eye out onto roofs from their downtown workplaces and discover them cluttered with dead and passing away birds.
During essential migration months — spring and fall — CBCM leads volunteer groups varying in between 8 and 20 individuals to walk high-rise buildings and scoop up fallen leaflets. They take the hurt ones to the Willowbrook Wildlife Center in Glen Ellyn for rehab and care, and take countless dead birds each year to the Field Museum, where they are contributed to the collection for documents and research study.
Using weather condition monitoring radar methods, real-time bird migration numbers can be discovered online at BirdCast. Researchers from the Field Museum are now likewise heading out throughout Illinois to perform a spring types count from the ground.
CBCM volunteer groups gather approximately 7,000 birds each year, about a quarter of which are hurt, said Prince.
“And that’s just the tip of the iceberg. That’s just what we’ve found, and what people report to us,” she said.
A study published in June discovered that bird accident death might be minimized by about 60% if synthetic light was halved. This would have international ramifications, as birds are a crucial part of managing pests, dispersing seeds, and pollinating plants.

Thrushes, orioles, woodpeckers, yellow-bellied sapsuckers and herons are amongst the types of birds she and her volunteers detect any provided early morning.
“The glass confuses them — because it’s clear and they think they can fly into it, or they think it’s a tree and it’s really the reflection of a tree,” said Prince.
Prince said often she discovers birds that weigh just 2 cents. They’re magnificent, she said. Bright orange, yellow and red.
