Cats are the No. 1 source of human-caused mortality in birds at an estimated four billion birds per year in the United States alone. The No. 2 cause is birds striking windows, with an estimated 365 to 988 million birds dying annually in the United States. One of the best ways to keep birds from hitting windows is to put a sticker or decal on the outside to break up the reflective pattern on it. ~ Doug Hitchcox, Maine Audubon Staff Naturalist
