"Chicago Buildings Prove Deadly for Migrating Birds: Preventing Collisions During Migration"

A record number of bird deaths from window collisions occurred in Chicago this week, with nearly 1,000 birds dying after striking the windows at McCormick Place convention center. This incident has alarmed the birding community, as it is the highest number of bird deaths documented in the past 40 years. The high-intensity rate of migrating birds passing over the city, combined with adverse flying conditions, led to an overwhelming number of birds near Chicago's Lake Michigan beachfront. Climate change has also been identified as a factor affecting birds, with evidence showing that birds in the Americas are getting smaller as the planet warms. Measures to prevent bird collisions include making windows more visible, reducing light pollution, and advocating for bird-safe building standards.
