Sparrow-Free Magic Halo
If you enjoy feeding wild birds, but find house sparrows, grackles, and bluejays have a tendency to "take over" at the feeders, discouraging smaller or less aggressive birds, and making a mess of your feeding stations, now you can dramatically improve your feeding program with the Sparrow-Free Magic Halo.
The Sparrow-Free Magic Halo is a patented wire hoop device with vertical extension wires that attaches easily to the top of a feeder. Studies have shown that certain bird species, including house sparrows, will not fly under these wires. Studies have shown the Sparrow-Free Magic Halo to be 99% effective in discouraging house sparrows, blue jays and common grackles.

*Sialis.org recommends the following: "TO PREVENT ENTANGLEMENT: Use very fine (28-30) gauge wire (e.g., for model airplanes) instead; or tie the line/wire to ground stakes or a second ring on the ground; or tie the line to springs attached to a stake or nail in the ground. If hobby wire lines are hanging free, use something heavy (a metal nut or fishing weight) to weight them down."
