I don’t know if you’ve ever driven through Atlanta but this building sits right along the 75/85 connector through downtown Atlanta. This stretch of road is 8-10 lanes on each side. I’m not a pigeon expert and they certainly the birds could still sit on the building but I’d say with all of the traffic, noise, smog could also detour the pigeons. Atlanta even posts smog alerts on the local news. This is not a typical owl to distract the birds IMO, and why gold? Can birds even see gold? According to my 2 minute internet research, yellow attracts birds. Just saying some variables to consider.
