I’ve seen the results of that syndrome, my neighbour who loved his flowerbeds, was suffering the depredations of squirrels, which he trapped, and relocated to the other end of the woods, about half a mile away. The traps were successively stolen, or smashed, by folks who “knew better” (or perhaps some Godzilla species of squirrel of which we remain to this day unaware). He gave up in the end, so everybody lost out. Some smug pillock probably still feels holier than my neighbour about it.
We were inundated with pigeons when they discovered they could nest under the solar panels. We had mesh fitted around the edges to keep them out, and fitted spikes on all the ridge tiles. Otherwise sleep was nigh impossible. I was astonished that the pigeons pretty much excluded the local seagulls, once they’d taken up residence. The seagulls don’t seem to like the spikes much so we didn’t get them back as residents, though they do still visit.
