Yesterday, nearly 1,000 migrating birds died after colliding with windows at Chicago's McCormick Place Lakeside Center, marking the most significant bird-fatality event in forty years of bird monitoring, as reported by the Chicago Tribune.
Experts have attributed the incident to a combination of factors including weather patterns and unfavorable rain timing. Further, the Lakeside Center's lit windows played a role in precipitating the disaster.
A massive migratory wave, declared as a once-in-a-generation event, had been observed by bird enthusiasts with extreme excitement as documented by WTTW News. To their dismay though, countless birds met fatal clashes with the city's lakefront buildings.
The event, described by Edward Warden, President of the Chicago Ornithological Society, as one of the biggest bird migrations in decades, saw a significant number of birds getting driven closer to the city by intense migration patterns and poor flying conditions, leading to the disastrous outcome at McCormick Place and potentially other lakefront buildings.
David Willard, a retired bird division collections manager at the Field Museum, speaks out on the colossal scale of the problem, stating estimated fatalities from bird/building collisions in the U.S. are around a billion annually. Following the incident, Annette Prince, Director of Chicago Bird Collision Monitors, has called for immediate action to mitigate the fatalities, underlining the urgency of addressing declining bird populations.
Certain corrective measures have been suggested but have yet to be widely executed. In spite of the Chicago City Council's 2020 ordinance asking newer buildings to incorporate bird safety measures, the required action is still missing. Notably, the "Lights Out" initiative, long recommended by bird activists and building managers, has been resisted by McCormick Place, resulting in persistent bird fatalities per reports from WTTW News.
The dedicated efforts of the Chicago Bird Collision Monitors, who have been rescuing avian crash victims across the city for over two decades, were needed the day of the incident when they discovered about 450 dead birds and saved nearly 300 injured birds, as noted in another Chicago Tribune article. Birds with minor injuries were sent to the Willowbrook Wildlife Center for a chance to recover and continue their migration journey.
