The Wisconsin Humane Society has recently launched the campaign WIngs: Wisconsin Night Guardians for Songbirds. The campaign focuses on the prevention of bird window collisions.
Birds may be confused by reflected landscapes in windows and crash into them. They might also see through a building’s windows on both sides and think they can fly through as if going through a tunnel. Night-migrating birds also may be confused by brightly lit buildings and fly towards them or around them until they become exhausted.
Here are some tips on how to prevent needless bird injuries and deaths from window collisions.
1. Close curtains to prevent the tunnel effect.
2. Apply window clings or ribbons to windows.
3. Install bird feeders very close or very far from windows.
There are more practical tips to be found on the WIngs website.
