Prevent birds from hitting your windows

According to The Cornell Lab, "Up to about 1 billion birds die from window strikes in the U.S. each year, according to a 2014 study."  To help combat this problem, they have compiled a list of ways to treat your windows to prevent collisions.  This is especially important if bird feeders are positioned near windows.  They recommend markings or netting to deter birds from seeing reflections and instead see a barrier to their flight path.  Furthermore, "to deter small birds, vertical markings on windows need to be spaced no more than 4 inches apart and horizontal markings no more than 2 inches apart across the entire window."*  Tempera paint, soap, decals (although hawk silhouettes are not effective), and dotted bird tape are among the suggested remedies for treating windows.
