When I first started using the FoxPro ecallers, it seemed like I was calling a coyote in every time I went out. I was using rabbit sounds most of the time. If I was targeting a bobcat, then I'd mix the sounds up, using bird calls as well. The past 2 years, the predator hunting here has flat sucked. I blame most of it on there being more hunters, and they're using more ecallers. Coyotes are smart, and they quickly get educated by the sounds from callers....especially so if the hunter doesn't know what he's doing. If someone goes out, and doesn't have an understanding of coyotes and their habits, then just starts playing rabbit in distress sounds, he's likely to educate at least 10 coyotes for the one he might kill. I am trying to call less, and use more sounds. including more coyote sounds. Last year, most of my success came during the coyote mating season, using howls. Watch the wind, set up in places where a coyote feels comfortable coming to a call, and don't overdo it.
