First wrong move: Hating them. If you chase a magpie with a broom, you’ve just given it a game. It will remember you, and it will tell its friends. Suddenly, you’re the target of a feathered mafia. Not a good look.
Second wrong move: Using poison or traps. Aside from being cruel (and often illegal), it’s just bad karma. Plus, magpies are so smart they’ll probably just watch you set the trap and then use it as a jungle gym.
Third wrong move: Shiny objects everywhere. I know the myth says magpies steal shiny things for their nests. But science says they’re actually a bit scared of new, shiny objects. So if you hang reflective tape, they’ll just find a new perch—one that’s right above your car. Congratulations, you played yourself.
