I've been feeding the local magpies and had them coming in every day on the deck about but at an angle so there was window glare for pictures, I moved the feeder table about 5 feet one day and they haven't been back since. There was other food in the yard they had claim to till 3 ravens showed up and ran them off. Now the ravens are guarding the food and teasing the magpies. Maggies are pacing back and forth cursing at them. Funny in the summer , Sparky the cat will be laying outside trying to take a nap or walking in the yard and the magpies have a blast teasing and pecking at him and chattering . They sure are fun to watch .
