As a former professional window cleaner, I know that there is almost nothing more pleasing for a homeowner than to have nice, clean windows. Windows so clean it’s like they are not even there. Unfortunately, windows so clean present a very clear danger to birds. Windows, clean or otherwise, can act as a mirror capturing the reflections of their surroundings. Birds will often see these reflections and mistake them as a part of their environment, often resulting in injury or death. Other times birds will see windows as open space, thus being a safe space to travel, again resulting in unfavorable outcomes. According to a 2014 study, up to 1 billion birds die each year from window strikes. Now, I’m not going to suggest that we all stop cleaning or neglecting our windows, but there are things we can do to lower the chances of bird strikes occurring at our homes.
Put things in your windows. Hanging plants, decals, or sun-catchers can be both attractive and deterring to birds. You can also get creative and use tempera paint or soap to draw or paint designs on your windows. Both will remain during rains but will wash off when scrubbed. Keep curtains closed when not using a room, this will help cut down on reflections and remove the appearance of dark spaces. Another idea is using ABC Bird Tape to break up the appearance of windows.
Additions to your windows could start with full window screens. Not always an option with old windows, but new windows will often support them. Installing sunshades or awnings help shelter windows making strikes less likely. Even placing netting in front of windows is an option in extreme cases. All things we can do to lessen our impact on the natural world.
