Hello all! I've been a birder for years, but I have a question I'm hoping someone can help me with. My place of work has a window about 5 ft up our wall, and in a nook between tha window and a concrete pillar, a robin has built her nest. She currently has 4 eggs. Sometimes when people come into the room and they notice the nest, they approach quickly. So far we've managed to keep anyone from scaring her away, but it's probably only a matter of time, and we're worried it will happen when the eggs hatch. We can't block the window, and we ourselves would like to be able to watch the nestlings grow, so I'm trying to find some sort of film cling that will block the bird from seeing us, but let us see the nest. Is there anything out there that is non-reflective (mirror like)? I assume a mirror appearance would cause her to think it was another bird and attack?
