Setting up a bird feeder at my place would be a deathrap for all birds, squirrels, and mice who try and take advantage of it. Why you ask?
One word: Cat
Our barn cat is barley a barn cat since we have almost no mice (she brought one home yesterday, so there are still some) Which means she does a good job but now that they don’t populate at all she dives in head first to any other creature she can find. This means if we ever planned to set up a bird feeder there would be no birds to feed from it after day 1.
