Bird-X Sparrow Free Magic Halo
In general, the songbirds we know and love approach feeders from the bottom, swooping in from below, coming up to their feeding spot. Pest and predatory birds like sparrows approach feeding spots from above, swooping down on on top of where they feed. The Sparrow Free Magic Halo allows you to take advantage of these natural tendencies to deter pest birds while keeping the beautiful and harmonious songbirds at your feeder.  Simply install it on any feeder birdhouse and you should see instant results.
