Very interesting. Last March when I was is Arizona, I called a Dawg in, directly behind me and to the right about a 100 yrds, I would of had to turn completely to shoot at it but I decided to wait, it would of seen me otherwise. I didnt want to move. There was a bird in a shrub about 15 feet behind me making all kinds of noise, and the dawg wouldnt present itself, it just kept on going out of site and I never saw it again. I am convinced that bird had something to do with it.
