The first birds of the spring migration season have already been observed in Chicago. These birds are unable to perceive glass, are confused by foliage in buildings, and see sky reflected in building glass. During migration, as they fly North to their breeding grounds, some birds strike windows and land on the sidewalks and streets. If you observe an injured bird, you may call the Chicago Bird Collision Monitors (CBCM) hotline at 773-988-1867. Hotline staff will respond and send someone quickly to retrieve the bird wherever it has been found, and there is helpful info at their webpage: https://www.birdmonitors.net/
Be aware that after birds strike windows they can remain unconscious but ALIVE for up to eight hours, so DO NOT assume they are dead. They may need immediate rescue to prevent further injury or being attacked by a predator. They may need medical assessment by federally licensed wildlife rehabilitators who will treat and release them upon recovery.
ALWAYS call the CBCM hot line first at 773-988-1867 – even if it appears the bird is not alive. Consider having this number listed in your mobile phone so it’s always at your fingertips! Leave a detailed voice message if they don’t pick up immediately, and leave your return phone number.
