I've only hunted crows a couple of times and each time we used an electronic call (my hunting partner's call) Electronic calls seem to work the best. It does kinda depend on how much you want to spend to hunt crows. I actually just bought a cheaper Johnny Stewart electronic call to hunt predators with. I'm guessing if I can find memory card with a crow call it should work just fine. I wasn't even thinking crows when I bought it. So if you also predator hunt or maybe you already have anelectronic call this would be an option if you want to spend the extra money. I know electronic calls work, but amouth call may work just fine also. I hope this helps.
