I just don't like seeing magpies and nothing else in a 10 mile radius!!! Cant be a natural balance??
Natural balances are what you get when humans don't interfere. If you're looking for natural balance, prehaps Birmingham isn't the best place to look If there are only magpies & nothing else as you say, which I doubt, then there won't be anything for them to eat so they will either move elsewhere or die. Your problem is solved, well part of it at least. I trust they do have shrinks in Brummie.
