This is the prime time of year for calling predators. The carnivores are lean and winter-hungry, and young varmints from last year will fall all over themselves trying to get to a squealing-rabbit call. A little later on, as the females get closer to whelping time, they get harder to fool, but for now, calling can be exciting sport.
