Well, since you may not be able to replace your current window panes with bird-safe glass, I refer you to research by Daniel Klem, Department of Zoology, Southern Illinois University at Carbondale, 1990.  He found that the only effective way to keep birds from striking windows was to place objects or patterns, 5-10 cm apart, uniformly over the whole window.  Another effective way, if you have, say, a bird feeder, was to place it almost right against the window, no more than 30cm away -- because birds will fly more slowly as they approach or leave it, and will be able to avoid the glass in time.  http://www.jstor.org/discover/10.2307/4513512?sid=21106110260513&uid=3739256&uid=2&uid=3739960&uid=4
