We have a customer from Fort Wayne IN mounting our Magic Halo over a Bluebird nest box. As many of you know, HOSP invading birdhouses and terrorizing native birds already using them is very disheartening, to say the least. Victims most often include Swallows and Bluebirds.
While we cannot guarantee positive results in birdhouse applications, our "test" customer is having wonderful success using the halo, having tried a "sparrow spooker" first without luck. Stay tuned for more updates as we learn of them!
