I’m lucky I live on the edge of the city locally we have more wood pigeon than Feral/ Rock pigeon. I see the feral pigeons in the city centre and tbh I’d be hard pressed to eat one, I supposed boil then roast and lots of hot sauce………… maybe if I was starving.

There are several videos on youtube of people hunting birds in the city with airguns and some really good catapult/ slingshot/ wrist rocket hunting videos.

If at first you don't succeed, excessive force is usually the answer.
