Update.
Well, I decided to go a different way altogether. I'm approaching this situation from another angle since yesterday, when I noticed the pigeons were actually nesting in one of our large planters. There was an egg. I scared away the mother and there it was. A lone egg.
Well.
This changed everything. It was now a family thing. The pigeons have begun muscling in on my turf. Just assuming that this is now their fuckin' home! Like shitting all over my deck up to this point hasn't been enough disrespect in itself? Fuckers. This is now personal. So, I decide to go mafia-style and off the kid. There's mom, on the next building over, maybe 20 feet away.I picked up the egg and threw it at her. (I missed). Maybe now they'll get the fuckin' message!
A little footnote to the above: The mom later came back and sat where the egg had been. I went out to scare her away, and she wouldn't budge. Like she didn't care if I just killed her or not. Just sat there and stared right at me. So I started beatin' at her with a stick...
