Chicago, IL (April 1, 2019) - Comprehensive study by Cornell Lab of Ornithology finds Chicago the most dangerous city for exposing migrating birds to the growing threat caused by light from large metropolitan areas.

In the words of the study, “The combination of large amounts of nocturnal illumination and their location in the most trafficked air space across the US elevate metropolitan Chicago, Houston, and Dallas to the top…. While all urban areas should take care to minimize ALAN (artificial light at night), our analysis indicates that actions taken in these particular cities would benefit the largest numbers of birds.”

Editorial: Bird populations face other threats, including climate change and habitat loss, that are much harder to solve than lethally transparent windows. No one set out to build perfect bird death traps, but expanses of reflective glass have turned out to be just that. Giving winged creatures a helping hand is the right response.

Chicago building managers and owners can take pride in participating in the nation’s most successful light reduction program for migratory birds. Lights Out! Chicago asks buildings to turn off or dim bright antenna, rooftop and display lights from 11pm to sunrise every spring and migration season. This act saves the lives of thousands of birds that would otherwise be attracted from their nightly travels towards the confusing city lights.

Shiny glass buildings are a hallmark of modern architecture, but for birds, that shimmer can be deadly. Every year, an estimated 100 million to 1 billion birds die by flying into glass windows. By studying how birds interact with buildings, architects and ornithologists are trying to create special features designed to keep birds alive.

Below, click around to see architectural features that can make buildings safer for birds — or more deadly.

The solutions to help reduce daytime bird collisions center on how buildings are designed. While a large amount of reflective glass may be aesthetically pleasing, it is more harmful to our feathered friends. Designing buildings with birds in mind would be one small part of the larger movement toward “greener” building design and construction
