Three times I've had grizzlies come when I was calling for something else, and one came at a fast ground-eating lope to a cow moose in heat sound. The others came more slowly and surreptitiously. None persisted when they discovered that a human was making the sound but I'd hate to bet my life on that. None of them ran away. One hid nearby, one stayed unmoving while I left and one moseyed away.
Making any kind of prey sound in bear country without considering that a bear might come is kind of short sighted. We've had a good many black bears come to rodent, rabbit and hoofed critter sounds, and had a cougar come to antler rattling, all incidental and separate from stands when we were intentionally calling bears or cougars. Engage brain, then make the call sound...
