The blue tape on our glass sliding door is at human eye level. The lower tape is at dog eye level. We did have a human walk into the door and break it years ago, and the dogs tend to go crazy when they see birds in the backyard and I don’t want them slamming into the glass (plate glass BTW; outlawed for this use in the USA 50 years ago).
Unfortunately, the pigeon paid no attention to either. RIP.
Poor pigeon!

As pigeons can see color (Tetrachromatic Vision Pigeons possess a remarkable tetrachromatic vision, which means they perceive four primary colors – ultraviolet, blue, green, and red), your pigeon was lacking in other skills – like thinking.
I actually ran over one of the smaller varieties. I wasn’t going fast, at all. It simply – apparently – didn’t think getting out of the middle of the road was a worthwhile expenditure of energy. I was sure it would.
