I have used my voice to owl call for probably the last 30 years, but I don't have a recording of it. I think it's the volume that works for me. My buddies will often make fun of how loud I owl hoot, but when it's crunch time they always turn to me and say hoot for us. My buddy in Ky one year had some gobblers roosting in an area and we went in one morning and he suggested we stop and locate them before moving on. Well he pulled out and tried two owl hooters and one crow call and promptly stated, they're not here, I guess. At that announcement I owl hooted with my voice and 4 gobblers opened up about 150 yards in front of us, we sat down and called them right to us. After that day he won't even pull out his owl hooter, he'll just ask me to do it. I think its a good quality, but not really sure as I've never heard it recorded, all that counts is I can make turkeys gobble. So don't worry about perfection, just go for it and make it loud. Well I have to confess I once done a breeding birds survey quadrant when i worked for DNR and listened to hours of recorded owl calls for the night raptor segment. I think that got me in tune. So see if there are any bird recordings of owls online. By the end of that survey I could get more responses from owls then the recordings, I even had owls come land right by me in the woods. I used to love doing a challenge sequence and the barred owls would be dive bombing me.
