No Stone Unturned

While I was walking near the Union Canal, I spotted those anti-roosting spikes on a ledge under the arch of a bridge. The constant deposition of wind-blown dirt and leaves from overhanging trees over the spikes had created a layer thick enough to allow the pigeons to nest on it. What used to be a deterrent was now providing a firm anchor for the nest's foundation. One day the next generation will hatch, ready to storm our cities and target the statues of our beloved heroic general, or proud statesman, or the occasional brilliant artist.
