Clearly a Pane

Are we all killing more birds than we know? Window strikes kill and maim a lot of birds every year. Exact numbers are hard to come by, but estimates based on over forty years of data range from 365 million to one billion birds killed every year in the US alone. The low estimate equals an average of one million day and this is happening day after day, year after year!

Is there a solution? Yes, technically this is solved. Dr. Daniel Klem figured out that horizontal markers (any visible pattern) every two inches or vertical markers every four inches does the trick. This has been coined the 2” x 4” Rule.

There are lots of easy ways we can prevent birds from colliding with our windows and below are some links to help guide you.
