We find that, overall, the Halo is about 85% effective according to those surveyed. Cheers, -Francis

Another observation: Because of the number of sparrows, I did pull the whole feeder down and kept it down for months. Then, when winter approached, I put the feeder and the halo back up, and no house sparrows made it through again. Did the adults who were defeating it before forget? Move on? Die? Who knows!
