Does It Feel Like Alfred Hitchcock's The Birds At Your Windows?

Does it seem like you are stuck in the horror movie The Birds with random birds hitting your home windows? Why causes this? The birds see the reflections of the sky and trees in the windows and think it is open territory to fly into. If this happens often a good solution is to put a window decal reprensenting the silhouette of a hawk which warns the birds that it is dangerous, stay away!
