Migrations are a particularly dangerous time for birds, which pass through Evanston in large numbers, risking collisions with windows. Between 500 million and 1 billion birds annually die in the United Statesfrom flying into windows, according to ornithologists. Window collisions are a leading cause of bird mortality and of population declines for once-common species.
Evanston is a stopover point for around 280 species – and millions of birds – that migrate through Evanston and Chicago, and stop at our lakefront every spring and fall. Tens of thousands of dead and injured birds have been found over the past 10 years in Evanston, at lakefront buildings, high-rise buildings downtown and at residences.
Here are ways to think through which of your windows might be dangerous and which solution work best for you.
Maybe you know a window where birds have hit. If you have heard a bird hit, other birdsmight have hit as well. Many times raccoons, gulls and other animals remove or eat dead birds so there is no evidence of a bird casualty.
If you do not know which windows are a particular threat, walk outside your house and look at your windows. Pay special attention to the first three floors. Here are some likely trouble spots:
Solutions are easy and inexpensive. If birds hit your windows, consider:
From things on-hand.

American Bird Conservancy shares brochures on bird-friendly design.
Bird friendly design strategies to reduce bird collisions and death, including consideration of overall architectural design to reduce hazards, the use of bird friendly materials, especially glass, exterior and interior lighting provisions and consideration of site planning and landscape design to reduce potentially hazardous situations."

Northwestern students Petition for Bird-Friendly Films at Mudd Library. Mudd Library accounts for over 14% of bird deaths and injuries on campus each year. Applying patterned window film to a portion of the building would dramatically reduce collisions that are fatal to birds.
