I cleaned out the part of the carport that was befouled by those pidges. A mountain of shit, twigs and broken eggs.
I had to fling one of them off the air conditioner the other night. They get very docile when it is dark and they are sleepy. It wouldn't fly off even when I was prodding it with the rake. I had to scoop and yeet it.
I think they have finally got the message and won't be back.
