I have had crows, hawks and owls 'investigate' rabbit distress calls when coyote hunting. So, I'm going to (in the near future when school allows /ubbthreads/images/graemlins/confused1.gif) mix some crow calls in with some rabbit distress as a confidence builder for coyote calling. I'm gonna go easy on the crow sounds not too loud or too frequent.
I mix some of my own sounds and use a homemade electronic caller.
My results have been mixed so far as I am just getting into coyote calling. And, my hunting (thus my learning) time has been very limited since March.
Stay in touch and I'll let 'ya know what happens.
I hope this helps.
Best of luck
Don
