This is an interesting and well researched article about a problem that I am sure each and every one of you have encountered over the years--birds flying into your window.

Each season, we have a different set of static clings on the windows (which are floor to ceiling) in an attempt to keep the birds from committing suicide--this article might help out her feats--and any of you who have a similar issue at your house.
