I don't know if this will pique anyone's interest, but this is the Lounge ...
I work in an interesting neighborhood. I recently changed jobs, and my building has a shower. Partly for the exercise and partly to avoid traffic, I come in early, walk 2 or 3 miles around the neighborhood and then shower. A couple of weeks ago I noticed a woman tossing something on the sidewalk in front of a building. When I came up I saw it was par-boiled rice (it looked like Uncle Ben's rather than Minute Rice). I'd noticed quite a few pigeons roosting in the area, and figured it was an attempt to kill a few pigeons (supposedly rice can swell in their digestive tract and kill them). I've seen the rice re-scattered every week. I've seen pigeons eating the rice occasionally, but I've not seen any carcasses. Yesterday I notice that a corner of the nearby building had wire spikes along the roof edge, and 7 papier mache owls at intervals as well. yesterday the pigeons were roosting on a street light arm across the street; today some were on the edge of that building, but not among the spikes or owls.
Much as I sympathize, I don't think the anti-pigeon measures are working.
