Regulations have existed in Chicago for over 50 years. The building predates it, and has been adding mitigations such as changing lighting and applying stickers for some time now.
This is not a common occurrence for the building in question.
Not just birds, but with everything else in life, I tend to first check if regulations exist before advocating for (more) regulation.
It’s not a binary question. Effective regulation (including timely updates such as mandating seat belts or airbags once they become possible) very much is a living ongoing project.
