Thank you so much for the interest everyone. I stopped production of the Halo device just for the Summer as we recollect parts and build inventory again. We tend to discourage Summer (July & Aug) mix-seed feeding in any case, since juvenile House Sparrows are generally immune to the wires and carry this into adulthood. This is where halo efficacy is somewhat lower in the Summer as seen in the U of Neb paper. Everything about this device is contained in my blog. Start home and scroll down, or at least check out these two: https://www.magichalo.org/2022/01/magic-halo-3-years-in-review.html https://www.magichalo.org/2022/01/magic-halo-3-years-in-revi... https://www.magichalo.org/2022/01/as-we-enter-our-4th-year.html https://www.magichalo.org/2022/01/as-we-enter-our-4th-year.h... We find that, overall, the Halo is about 85% effective according to those surveyed. Cheers, -Francis
