3. When we moved into a new building, birds did this a lot

9. Dubious

Animals don't have out ability of abstraction. They rarely can look at something in 2-D and recognize it as the 3-D object. And since these aren't moving, they probably don't really recognize it as a "bird in flight". It's just a "black spot on a window".

had a good article about this a few years back. There is a company in Germany that makes special non-reflective glass to stop bird strikes. Hopefully more manufacturers will start producing it.
