Hereabouts, every business had trouble with pigeons, and some even had bb guns around and folks would shoot every one they could. Thousands of them. In the last few weeks I've looked for them, haven't found a one.
I'm not fond of them, it's just a point of curiosity.
Yes, we have some peregrines about, and a lot of hawks, but they would have had to eat about ten thousand pigeons each to get rid of all these.....
