If you don't want Dastardly Rodebirds or Gray Squirrel birds at your feeders, move them away from any branch or other structure. Squirrel bafflers sometimes work, but keep this feeder less than 5 feet away from a window, so birds aren't going fast enough to seriously injure themselves if they fly off the feeder and into your window.
