BirdBustersBirdsGottaGo Distress & Predator Calls CD - Starling Crows Grackle Red Tail Goshawk​- Scare Away starlings Crows and grackles

Our yard at our prior house about 250 miles southwest of Washington, DC, was overrun by crows who scared off the song birds. We hate crows.We brought this on June 3, 2020, after our son-in-law told us that a bird buster style of CD was played on the loud speaker system before his football games in northern NJ to scare away pigeons. We have tried this one for crows at least 7-8 times. It has worked every time. So each time it has worked and the time in between has lengthened. Today we tried it to scare off the crows in the yard behind us. It worked for that too.But we live within the I-495 Capital Beltway and our yard is only about .3 of an acre.I will post an update if anything changes. But so far it beats Cornell University's suggestion of shining reflective CD disks or other such items that could clang together and scare away crows. Of course I haven't taken those down. But they hadn't worked until this CD.My only wish is I wanted it to be a little bit louder. But I am playing it through an old CD player with no amplification.Hope this is worthwhile in your decision.Tom LeggetteAuthor Consumer Contract Law in VirginiaVA. Continuing Legal Education
