I call ALOT, Bearmanric called in my sons first bear.
Rabbit call will work, more like a jack then a cotten tail, a little deeper sound. Ever heard abear cub? thats what I try to sound like.
Calf elk calls or fawn sounds too. or you could try to sound like a big bucket of honey or pan of bacon

Bears are not allowed to sneak up and eat you here, that would be baiting.
