Volunteers and staff from Northwestern University conducted a search of downtown Chicago and the university's Evanston campus after more than a thousand birds were discovered dead or injured from striking buildings during the recent fall migration.
The search occurred over the weekend preceding October 20, 2026, and highlights the danger that the city's high-rise structures present to migrating birds each autumn.
