Magic Halo

Magic Halo Disclaimer

Please Read First

We cannot guarantee that the Magic Halo is House Sparrow-proof for all bird feeders, given the myriad of designs on the market. Though our survey data is largely favorable, it is also limited to just 15% of our customers who choose to participate. Some of them do report House Sparrows (HOSP) overcoming the Magic Halo and its hanging wires - particularly in times of poor weather and/or desperation. Factors may include nearby structures, the desirability of the food, visibility conditions that sharpen/blur perception of the hanging wires, availability of other food nearby, harshness of Winters, etc. 


The original Paper from the University of Nebraska published in 1994 did confirm that Juvenile HOSP are Halo-tolerant, and it is poorly understood at what point they turn adult and how many there are at any given time. HOSP can have multiple broods through August. The study cited 2-11% of HOSP visiting feeders with Halos did manage to breach, including juveniles, leaving an approx 90% success rate. Juveniles are much fewer than adults, but it further confuses the results that one might expect because they can be more abundant in some areas over others.


Before deciding to purchase a Magic Halo, we strongly advise potential customers to read the following from FeederWatch and Sialis first. Attention should also be paid to recommended seed type(s), and to avoid mixing, especially with known HOSP-friendly varieties such as millet.


We appreciate your understanding.


Feed-on, HOSP-free!
