The Quaker Boy Howler Pack contains three separate mouth calls. As with people, coyotes have voices that differ with sex and age. This family pack will enable you to make all the different sounds a pack of coyotes may make. This is done by varying the thickness of the reeds and in the configuration of the sound chambers. The Alpha Male call will be the courser males. The Female call reproduces their yips and the Pup call will be the higher pitched juvenile.
