Okay, time for the fun stuff. You can scare pigeons away with objects that look like predators. Fake owls and snakes are classic choices, but here’s the secret: pigeons are not idiots. If the owl sits in the same spot for a week, they’ll start posting memes about it.

Move the decoy around every few days. Change its location, tilt its head, give it a sunglasses upgrade. Make it look alive. Or better yet, get a wind-up one that moves—pigeons hate dance moves.
