Chicago is known to be dangerous for migrating birds, with a glassy conference center posing a significant threat.
During peak spring migration in April, many birds were at risk due to confusion with glass reflections and city lights.
Volunteers were called upon to rescue injured birds in Chicago, where a conference venue caused harm to many birds.
The conference center at McCormick Place in Chicago implemented new protections after causing the death of nearly a thousand birds in a single day in October 2023.
