How can I stop a male robin bird from tapping on my window all day long?
He is probably fighting with the “other bird” he sees there – his reflection. He sees it as an invader in his territory. Here is an excellent website that explains why birds peck at windows, and fly into windows and doors, and how to prevent it. http://www.sialis.org/windowstrikes.htm Also, if a bird gets injured flying into your windows, here is what you should do: Place the bird in a box lined with paper towels, not cloth, as the bird’s nails could get caught in the material. Cover the box and place it in a warm, dark, quiet area. Do not allow any animals, children or excitable adults near it. In about 45 minutes to an hour, take the box outside, open it and see if the bird will leave on its own. If it is still stunned, or showing other signs of injury, keep it in the box and contact a licensed wildlife rehabilitator. You should be able to find one here:
