All over Seattle you see spikes and wires added to the tops of lights to discourage perching seagulls, crows, and pigeons. It’s an only somewhat successful idea as I’ve seen plenty of birds carefully standing amongst the sharp points. At least in this case the wires are part of the design in an attempt to make it more attractive, unlike the majority where it’s added as an ugly afterthought. Still looks a bit silly though.
Cee’s B&W Challenge this week has the topic of lights.
