I have been useing strickly slate calls for most of my turkey hunting carreer, but for the last two years I wanted to try somthing different. I was interested in trying to make my own wing bone call and kill a bird with it. So I made one out of the wing bones of a bird a couple years ago and after practiceing all year I got pretty good. The only sound I could do though was a yelp. Not sure if you can make any other sounds with it or not? But I ended up calling in a bird opening day with it and shot it within the first hour of my hunt. Around here, after a few days of people chaseing birds around the birds got wise and call shy. Well, my friend wanted me to take him and I told him I was going to try to use a wingbone call and he didnt like that idea so we stuck to the slate call for awhile. After two hours of nothing, I told him I wanted to give my wing bone call a chance at our next calling location. I called three times a bird gobbled back in the timber about 75 yards away. So we hurried up and sat up and while trying to find a spot I lost my call. Then the bird started getting gobble crazy so out of nowhere I decided to cuff my hands and attempt to try to make a yelp and I ant going to lie, It sounded good. I stopped calling and the was in hour face and down stone cold before I had any idea what had just happend. I think that this call can be very effective when Birds have heard most every other call and this call has a sound of its own that most birds have never heard. Anybody outhere have any luck with this call, and can make other sounds besides a yelp.
