Pigeons are really sensitive to infrasound. It causes them to take flight immediately.
I built a device that created a ~1cm arc to scare away pigeons. You don't need to electrocute them, the sound alone does the job. I don't believe they can develop a tolerance as it is a survival instinct from living in cliff faces.
