Windows are deadly for birds.
More birds die each year from crashing into homes and buildings than are killed by wind turbines and vehicles combined. In Canada it's the third leading cause of wild bird death, after cats (domestic and feral) and power lines, collisions and electrocutions. Window strikes kill about 100 million birds in North America each year.
Birds can't see glass. And they fly so fast, any collision is usually fatal.
Here are some simple, affordable changes you can make at home or work to prevent these deaths:
- Close blinds and curtains
- Move indoor plants away from windows
- Hang old CDs, aluminum pie plates or chimes to break up the expanse of exposed glass
- Plant a shade tree to cut down on reflection
- Dim or turn off lights, especially during spring and fall migration
- Install special screens to cushion impact
- Source bird-friendly tape

Do you feed birds in winter?
Your bird feeder can be an important source of calories for wild birds. Be sure any feeders and bird baths are a half a metre (or less) away from glass surfaces. This will stop birds from building up too much momentum.
