Obviously dont howl...i dont use jack sounds, lots of bird and pup sounds, occasional cottontail. they love pup whimpers and lip squeaksand mouse squeakers. They like high pithced shrill sounds, I have found the tweety psycho to be very good. i dont beleive they use thier nose as much as coyotes but they do use thier ears, maybey more, they can key in on low frequency underground digging and i believe they can hear you moving as well. I am the only one hunting the population i go after and they usually come in in about 20 minutes. In a few weeks the prego females will be in thier dens for a month or so and the males and helper females will be hunting to keep her and the kits fed.
