I wonder if the Tom Austin with the foxpro team is related to the Bill Austin from Wy . Bill has been gone for a lot of years now but he was one of the first people that talked of the coyote language and marketed a coyote howler . Actually he had two howlers a male and female at first then a pup howler latter on . I still have one of the male howlers he made and if I looked hard enough I probably can dig up his instructional tape where he talked of the different sounds coyote make why and how . Now that guy was a wealth of coyote knowledge as was Vern Dorn , Bill Nelson and others that have passed on . There are still others out there that are as well like Craig O-Gorman and a few others they are all getting up in years now and have taken far more coyote then me . I only averaged 216 coyote a year for 36 years some years more some years less my best day was 19 called and killed , but I have had a lot of no coyote days also . I never counted the pups as coyote taken nor did I include the ones shot from the chopper as they were counted by the pilot as his take , he got paid per coyote also . I did once take 4 dens in one day when I was locating for the Gov. plane that averaged 7 pups per den , that was a long day starting before day break and ending after sunset with a lot of miles on my truck and feet . I liked to use my hand held howler to locate as so many of the other guys used the siren or group howls from their Foxpro callers and often the local coyote didn't want to talk for them any more . I kept changing my methods for taking coyote but they still nearly always fell to the sounds that Bill Austin had taught me as well as the sounds that the coyote them selves taught me . Some of the best scents for trapping that I found over the years for trapping were wily red 500 from Hawbecker and set freshener #6 from O Gorman and not a lot of it per set a small drop on a cotton ball with a wire pushed through it so it could be held in place made a scent holder and sight attraction . I have on trap educated coyote used a small cow pie as both put near a small sage brush backing on the up wind side of a cow trail maybe up to 5 feet from the trail . I also have used just blood from another coyote as lure for trap shy coyote and at times the back end parts of a coyote as a small tuft of fur and scent after I had skinned them out , it seemed to work best if it was a coyote from that area as they knew it's smell . The size of your imagination is your limiting factor as well as your desire to study and learn from them when it comes to animals they know more about them selves and others of their own kind then any body else does .
