Preventing Bird Collisions in NYC
Right now, millions of birds are migrating south. But for many woodcocks, warblers, and sparrows, their journeys will tragically end here in NYC. Up to a quarter million birds die each year after crashing into New York’s reflective windows. Thankfully, there are easy solutions we can all do to make the City safer for birds.
Turn off the lights at night. Nighttime light pollution disrupts birds’ navigational cues.
To protect migrating birds from crashing into windows in New York City, several effective strategies can be implemented.
Bird-Friendly Window Treatments
Installing specific window treatments can significantly reduce the risk of collisions:
• Decals: Use bird-safe decals that break up reflections.
• Screens: Install screens on windows to create a barrier.
• Films: Apply window films designed to reduce reflections.
Additional Measures
In addition to window treatments, consider these practices:
• Keep Windows Clean: Regularly clean windows to minimize reflections that can confuse birds.
• Minimize Indoor Lighting: Reduce indoor lighting at night, especially during migration seasons, to prevent attracting birds to buildings.
