I lived in a building which was "affected" by pigeons, they filled the nearby balconies with their feces. It was disgusting. I complained to management, nothing was done. They were loud and annoying early in the morning, crapped all over everything, it was maddening. Although pigeons are pretty smart, you can teach them to fear you and even to fear coming anywhere near your balcony, which is what I did. By constantly scaring the bejeesus out of them every time they came near. They eventually decided that the pleasure of crapping on my balcony wasn't worth the terror I would inflict on them.

I had a pigeon problem at one of my previous gigs. The fire escape (where we’d frequently go out to smoke/vape, or try to) was a biohazard area. There was an inches-thick layer of fecal matter coating the ground, it was crackling if you attempted to walk on there, and the smell was toxic. Nevertheless, the pigeons appreciated this situation and were nesting in there. Something was regularly killing them (either a predator or disease) and so someone had to undertake the perilous task of disposing of the bodies otherwise they’d stink up the place even more. I still remember sending an invoice with a “dead pigeon removal” line item.
