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.
- University developed
- 99% effective in studies
- Any feeder: hanging, tube, stationary or hopper

The Magic Halo was developed after decades of research into risk aversion and foraging habits of birds by Dr. R.J. Johnson, professor of Wildlife Biology and Extension Wildlife Specialist in the School of Natural Resources at the University of Nebraska, Lincoln.

*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."
