The rabbit, jack or cottontail, has called in more coyotes through the years than any other. And, don't be fooled into thinking that just because there are no jack rabbits with-in 1000 miles off your hunting area that it won't work, because it will.
We are also coming into the part of the year that howling will produce action well. Might try woodpecker distress also, it seems to produce well for a lot of callers.
