I've called in a pack of coyotes while squirrel hunting with my squirrel call. They came in looking for a squirrel, eyes in the trees, and not on my .22. The only 'yotes I've killed with a .22, they were only around 10-15 yards and had no idea I was there. The first one was hit right between the eyes. The second was hit in the base of the skull at around 20 yards while he was running off. So, yeah, squirrel calls get coyotes.
